ABSTRACT

Serous cystic neoplasm (SCN) represents 10–16% of cystic pancreatic lesions, first classified by Compagno and Oertel at 1978. In contrast to mucinous cystic neoplasm or intraductal papillary mucinous neoplasm of pancreas which have malignant potential, SCN is thought to be exclusively benign as solitary lesion in nearly all cases. There has been rare reported association between the SCN and pancreatic ductal adenocarcinoma, and few cases were documented their coexistence. In this report, we present the case of SCN of the pancreas with literature review in which synchronous pancreatic ductal adenocarcinoma and pancreatic intraepithelial neoplasm coexist together.

ABSTRACT

BACKGROUND: There has been no practical guidelines for the management of patients with central nervous system (CNS) tumors in Korea for many years. Thus, the Korean Society for Neuro-Oncology (KSNO), a multidisciplinary academic society, started to prepare guidelines for CNS tumors from February 2018. METHODS: The Working Group was composed of 35 multidisciplinary medical experts in Korea. References were identified through searches of PubMed, MEDLINE, EMBASE, and Cochrane CENTRAL using specific and sensitive keywords as well as combinations of keywords. RESULTS: First, the maximal safe resection if feasible is recommended. After the diagnosis of a glioblastoma with neurosurgical intervention, patients aged ≤70 years with good performance should be treated by concurrent chemoradiotherapy with temozolomide followed by adjuvant temozolomide chemotherapy (Stupp's protocol) or standard brain radiotherapy alone. However, those with poor performance should be treated by hypofractionated brain radiotherapy (preferred)±concurrent or adjuvant temozolomide, temozolomide alone (Level III), or supportive treatment. Alternatively, patients aged >70 years with good performance should be treated by hypofractionated brain radiotherapy+concurrent and adjuvant temozolomide or Stupp's protocol or hypofractionated brain radiotherapy alone, while those with poor performance should be treated by hypofractionated brain radiotherapy alone or temozolomide chemotherapy if the patient has methylated MGMT gene promoter (Level III), or supportive treatment. CONCLUSION: The KSNO's guideline recommends that glioblastomas should be treated by maximal safe resection, if feasible, followed by radiotherapy and/or chemotherapy according to the individual comprehensive condition of the patient.

ABSTRACT

BACKGROUND: There was no practical guideline for the management of patients with central nervous system tumor in Korea in the past. Thus, the Korean Society for Neuro-Oncology (KSNO), a multidisciplinary academic society, developed the guideline for glioblastoma successfully and published it in Brain Tumor Research and Treatment, the official journal of KSNO, in April 2019. Recently, the KSNO guideline for World Health Organization (WHO) grade III cerebral glioma in adults has been established. METHODS: The Working Group was composed of 35 multidisciplinary medical experts in Korea. References were identified by searches in PubMed, MEDLINE, EMBASE, and Cochrane CENTRAL databases using specific and sensitive keywords as well as combinations of keywords. Scope of the disease was confined to cerebral anaplastic astrocytoma and oligodendroglioma in adults. RESULTS: Whenever radiological feature suggests high grade glioma, maximal safe resection if feasible is globally recommended. After molecular and histological examinations, patients with anaplastic astrocytoma, isocitrate dehydrogenase (IDH)-mutant should be primary treated by standard brain radiotherapy and adjuvant temozolomide chemotherapy whereas those with anaplastic astrocytoma, NOS, and anaplastic astrocytoma, IDH-wildtype should be treated following the protocol for glioblastomas. In terms of anaplastic oligodendroglioma, IDH-mutant and 1p19q-codeletion, and anaplastic oligodendroglioma, NOS should be primary treated by standard brain radiotherapy and neoadjuvant or adjuvant PCV (procarbazine, lomustine, and vincristine) combination chemotherapy. CONCLUSION: The KSNO's guideline recommends that WHO grade III cerebral glioma of adults should be treated by maximal safe resection if feasible, followed by radiotherapy and/or chemotherapy according to molecular and histological features of tumors.

ABSTRACT

BACKGROUND: There was no practical guideline for the management of patients with central nervous system tumor in Korea for many years. Thus, the Korean Society for Neuro-Oncology (KSNO), a multidisciplinary academic society, has developed the guideline for glioblastoma. Subsequently, the KSNO guideline for World Health Organization (WHO) grade II cerebral glioma in adults is established. METHODS: The Working Group was composed of 35 multidisciplinary medical experts in Korea. References were identified by searching PubMed, MEDLINE, EMBASE, and Cochrane CENTRAL databases using specific and sensitive keywords as well as combinations of keywords regarding diffuse astrocytoma and oligodendroglioma of brain in adults. RESULTS: Whenever radiological feature suggests lower grade glioma, the maximal safe resection if feasible is recommended globally. After molecular and histological examinations, patients with diffuse astrocytoma, isocitrate dehydrogenase (IDH)-wildtype without molecular feature of glioblastoma should be primarily treated by standard brain radiotherapy and adjuvant temozolomide chemotherapy (Level III) while those with molecular feature of glioblastoma should be treated following the protocol for glioblastomas. In terms of patients with diffuse astrocytoma, IDH-mutant and oligodendroglioma (IDH-mutant and 1p19q codeletion), standard brain radiotherapy and adjuvant PCV (procarbazine+lomustine+vincristine) combination chemotherapy should be considered primarily for the high-risk group while observation with regular follow up should be considered for the low-risk group. CONCLUSION: The KSNO's guideline recommends that WHO grade II gliomas should be treated by maximal safe resection, if feasible, followed by radiotherapy and/or chemotherapy according to molecular and histological features of tumors and clinical characteristics of patients.

ABSTRACT

OBJECTIVES: The aim of this study was to compare root canal volume change and canal transportation by Vortex Blue (VB; Dentsply Tulsa Dental Specialties), ProTaper Next (PTN; Dentsply Maillefer), and ProTaper Universal (PTU; Dentsply Maillefer) nickel-titanium rotary files in curved root canals. MATERIALS AND METHODS: Thirty canals with 20°–45° of curvature from extracted human molars were used. Root canal instrumentation was performed with VB, PTN, and PTU files up to #30.06, X3, and F3, respectively. Changes in root canal volume before and after the instrumentation, and the amount and direction of canal transportation at 1, 3, and 5 mm from the root apex were measured by using micro-computed tomography. Data of canal volume change were statistically analyzed using one-way analysis of variance and Tukey test, while data of amount and direction of transportation were analyzed using Kruskal-Wallis and Mann-Whitney U test. RESULTS: There were no significant differences among 3 groups in terms of canal volume change (p > 0.05). For the amount of transportation, PTN showed significantly less transportation than PTU at 3 mm level (p = 0.005). VB files showed no significant difference in canal transportation at all 3 levels with either PTN or PTU files. Also, VB files showed unique inward transportation tendency in the apical area. CONCLUSIONS: Other than PTN produced less amount of transportation than PTU at 3 mm level, all 3 file systems showed similar level of canal volume change and transportation, and VB file system could prepare the curved canals without significant shaping errors.

ABSTRACT

This study investigated the effects of ombuoside, a flavonol glycoside, on dopamine biosynthesis in PC12 cells. Ombuoside at concentrations of 1, 5, and 10 µM increased intracellular dopamine levels at 1 – 24 h. Ombuoside (1, 5, and 10 µM) also significantly increased the phosphorylation of tyrosine hydroxylase (TH) (Ser40) and cyclic AMP-response element binding protein (CREB) (Ser133) at 0.5 – 6 h. In addition, ombuoside (1, 5, and 10 µM) combined with L-DOPA (20, 100, and 200 µM) further increased intracellular dopamine levels for 24 h compared to L-DOPA alone. These results suggest that ombuoside regulates dopamine biosynthesis by modulating TH and CREB activation in PC12 cells.

ABSTRACT

PURPOSE: Posthepatectomy liver failure is a serious complication and considered to be caused by increased portal pressure and flow. Splanchnic vasoactive agents and propranolol are known to decrease portal pressure. The aim of this study was to identify optimal candidates with potential for clinical use among somatostatin, terlipressin, and propranolol using rats with 90% hepatectomy. METHODS: Rats were divided into 5 groups: sham operation (n = 6), control (n = 20), propranolol (n = 20), somatostatin (n = 20), and terlipressin group (n = 20). Seven-day survival rates and portal pressure change were measured, and biochemical, histologic, and molecular analyses were performed. RESULTS: Portal pressure was significantly decreased in all 3 treatment groups compared to control. All treatment groups showed a tendency of decreased liver injury markers, and somatostatin showed the most prominent effect at 24 hours postoperatively. Histologic liver injury at 24 hours was significantly decreased in propranolol and terlipressin groups (P = 0.016, respectively) and somatostatin group showed borderline significance (P = 0.056). Hepatocyte proliferation was significantly increased after 24 hours in all treatment groups. Median survival was significantly increased in terlipressin group compared to control group (P < 0.01). CONCLUSION: Terlipressin is considered as the best candidate, while somatostatin has good potential for clinical use, considering their effects on portal pressure and subsequent decrease in liver injury and increase in liver regeneration.

ABSTRACT

OBJECTIVE: Tumor necrosis factor-alpha (TNF-alpha) inhibitors are used as a treatment in various immune-mediated inflammatory diseases (IMIDs). Tuberculosis (TB) risk is reported in several meta-analyses in patients treated with TNF-alpha inhibitors. The purpose of this study is to collect, review, and evaluate the TB risk in TNF-alpha inhibitors according to IMIDs indications and between soluble-receptor TNF-alpha inhibitor and monoclonal-antibody TNF-alpha inhibitors. METHODS: A systematic literature search on systematic reviews and meta-analyses was performed in PubMed, MEDLINE, Cochrane library, and EMBASE. We identified meta-analyses that evaluated TB infection risk of TNF-alpha inhibitors in IMIDs patients. RESULTS: Thirteen meta-analyses including 41 study results were included in this umbrella review. IMIDs patients treated with TNF-alpha inhibitors had an increased risk of TB than control group (placebo with or without standard therapy patients) (relative risk ratio (RR) 2.057, 95% confidence interval (CI) 1.697 to 2.495). Among them, RA patients with TNF-alpha inhibitors had a higher risk of TB than control group (RR 1.847, 95% CI 1.385 to 2.464), and non-RA patients with TNF-alpha inhibitors had an increased risk of TB (RR 2.236, 95% CI 1.284 to 3.894). In subgroup analysis on TB risk between soluble-receptor TNF-alpha inhibitor and monoclonal-antibody TNF-alpha inhibitors in RA patients, the analysis indicated that monoclonal-antibody TNF-alpha inhibitors had higher risk of TB than solublereceptor TNF-alpha inhibitor (RR 2.880, 95% CI 1.730 to 4.792). CONCLUSION: This umbrella review confirms that the risk of TB is significantly increased in TNF-alpha inhibitor treated patients compared to control group.

ABSTRACT

OBJECTIVE: This study was aimed to evaluate the effectiveness of the diabetes education program implemented in a community hypertension and diabetes education center. METHODS: Participants were thirty nine diabetic patients who received the education program in the center from May 2014 through May 2015. The education program consisted of two sessions for 2 days (45 minutes per session) regarding clinical information, nutrition and exercise for type 2 diabetes patients. Initially, they were assessed for general characteristics, knowledge on diabetes, self-efficacy and self-care behaviors. Reassessment was performed on their knowledge and self-efficacy directly after the program, and on self-care behaviors at 12 weeks after the program. RESULTS: The mean score of diabetes knowledge was significantly increased from 5.27±2.10 to 8.21±1.20 (p < 0.001) between before and after the program. The self-efficacy score was also significantly increased from 6.88±1.72 to 8.16±1.47 (p < 0.001). The self-care behavior score was significantly increased from 3.59±1.89 before the program to 4.35±1.29 (p < 0.001) at 12 weeks after the program. CONCLUSION: The diabetes education program may be effective on the improvement of knowledge, self-efficacy and self-care behaviors in type 2 diabetic patients.

ABSTRACT

BACKGROUND: Sorbus rufopilosa, a tsema rowan, is a species of the small ornamental trees in the genus Sorbus and the family Rosaceae found in East Asia. The bioactivities of S. rufopilosa have not yet been fully determined. The objective of this study is to evaluate the antioxidant and anticancer effects of ethanol extract of S. rufopilosa (EESR) and to determine the molecular mechanism of its anticancer activity in human colon carcinoma HT29 cells. METHODS: To examine the antioxidant activity of EESR, 2,2-diphenyl-1-picrylhydrazyl radical scavenging activity assay was performed. Inhibitory effect of EESR on cancer cell growth and proliferation was determined by water-soluble tetrazolium salt assay. To investigate the mechanism of EESR-mediated cytotoxicity, HT29 cells were treated with various concentrations of EESR and the induction of cell cycle arrest and apoptosis was analyzed by flow cytometry, 4,6-diamidino-2-phenylindole staining, and Western blot analysis. RESULTS: EESR showed significant antioxidant activity and inhibitory effect on HT29 cell growth in a dose-dependent manner. EESR induced cell cycle arrest at G2/M phase in a dose-dependent manner by modulating cyclin B, cyclin-dependent kinase 1 (CDK1), and CDK inhibitor p21 expression. EESR-induced apoptosis was associated with the upregulation of p53, a death receptor Fas, and a pro-apoptotic protein Bax and the activation of caspase 3, 8, and 9, resulting in the degradation of PARP. CONCLUSIONS: EESR possessing antioxidant activity efficiently inhibits proliferation of HT29 cells by inducing both cell cycle arrest and apoptosis. EESR may be a possible candidate for the anticancer drug development.

ABSTRACT

The goal of this study was to determine whether gypenosides (GPS) exert protective effects against dopaminergic neuronal cell death in a 6-hydroxydopamine (OHDA)-lesioned rat model of Parkinson's disease (PD) with or without long-term 3,4-dihydroxyphenylalanine (L-DOPA) treatment. Rats were injected with 6-OHDA in the substantia nigra to induce PD-like symptoms; 14 days after injection, groups of 6-OHDA-lesioned animals were treated for 21 days with GPS (25 or 50 mg/kg) and/or L-DOPA (20 mg/kg). Dopaminergic neuronal cell death was assessed by counting tyrosine hydroxylase (TH)-immunopositive cells in the substantia nigra and measuring levels of dopamine, norepinephrine, 3,4-dihydroxyphenylacetic acid (DOPAC), and homovanillic acid (HVA) in the striatum. Dopaminergic neuronal cell death induced by 6-OHDA lesions was ameliorated by GPS treatment (50 mg/kg). L-DOPA treatment exacerbated 6-OHDA-induced dopaminergic neuronal cell death; however, these effects were partially reversed by GPS treatment (25 and 50 mg/kg). These results suggest that GPS treatment is protective against dopaminergic neuronal cell death in a 6-OHDA-lesioned rat model of PD with long-term L-DOPA treatment. Therefore, GPS may be useful as a phytotherapeutic agent for the treatment of PD.

ABSTRACT

BACKGROUND: Osmanthus matsumuranus, a species of Oleaceae, is found in East Asia and Southeast Asia. The bioactivities of O. matsumuranus have not yet been fully understood. Here, we studied on the molecular mechanisms underlying anti-cancer effect of ethanol extract of O. matsumuranus (EEOM). METHODS: Inhibitory effect of EEOM on cell growth and proliferation was determined by WST assay in various cancer cells. To investigate the mechanisms of EEOM-mediated cytotoxicity, HepG2 cells were treated with various concentration of EEOM and analyzed the cell cycle arrest and apoptosis induction by flow cytometry, Western blot analysis, 4,6-diamidino-2-phenylindole (DAPI) staining and DNA fragmentation. RESULTS: EEOM showed the cytotoxic activities in a dose-dependent manner in various cancer cell lines but not in normal cells, and HepG2 cells were most susceptible to EEOM-induced cytotoxicity. EEOM induced G2/M arrest in HepG2 cells associated with decreased expression of cyclin-dependent kinase 1 (CDK1), cyclin A and cylcin B, and increased expression of phospho-checkpoint kinase 2, p53 and CDK inhibitor p21. Immunofluorescence staining showed that EEOM-treated HepG2 increased doublet nuclei and condensed actin, resulting in cell rounding. Furthermore, EEOM-mediated apoptosis was determined by Annexin V staining, chromatin condensation and DNA fragmentation. EEOM caused upregulation of FAS and Bax, activation of caspase-3, -8, -9, and fragmentation of poly ADP ribose polymerase. CONCLUSIONS: These results suggest that EEOM efficiently inhibits proliferation of HepG2 cells by inducing both G2/M arrest and apoptosis via intrinsic and extrinsic pathways, and EEOM may be used as a cancer chemopreventive agent in the food or nutraceutical industry.

ABSTRACT

This study assessed main pulmonary artery diameter of patients with anthracofibrosis. Patients with anthracofibrosis and CT scans were evaluated after exclusion of patients with co-existing disease. We measured the diameter of the main pulmonary artery (PAD) and ascending aorta (AD) and calculated the pulmonary artery to aorta ratio (APR). The upper reference limit for comparison of PAD was 29 mm. Cut-off values for PAD and APR indicating pulmonary hypertension were 33 mm and 1. We correlated the CT parameters with echocardiographic results. Total 51 patients were included in the analysis. The mean PAD, AD, and APR were 33 mm, 38 mm, and 0.87 respectively. The PAD was larger than the upper reference limit, 29 mm (P33 mm in 30 (65%) and the APR was >1 in 9 patients (18%). Of 21 patients with echocardiography, 11 (52%) were found to have pulmonary hypertension. There was no statistical difference in the diagnosis of pulmonary hypertension between echocardiography and CT (P=1.000). In conclusion, main pulmonary artery is dilated in patients with anthracofibrosis more than in the healthy population.

ABSTRACT

BACKGROUND/AIMS: Our aim was to assess the long-term data regarding efficacy and safety of infliximab (IFX) treatment for refractory Crohn's disease (CD) patients in our tertiary teaching hospital. METHODS: We have retrospectively analyzed the medical records of 89 CD patients who underwent IFX treatment between March 2003 and February 2011 at Kyung Hee University Hospital (Seoul, Korea). The primary outcome measurements were the rates of initial clinical response (CR) at 10 weeks after the 1st IFX infusion and sustained CR at the end of the follow-up. Overall adverse events related to IFX treatment were also evaluated. RESULTS: The mean (SD) follow-up period of eligible 80 patients was 33.7 (21.9) months. A total of 77 patients (96%) showed initial clinical response, but 8 patients showed loss of response to IFX during the follow-up. Finally, 59 patients (59/77, 76.6%) showed sustained CR at the end of the study. Logistic regression analyses showed that an initial CR at 10 weeks was the independent predictor associated with sustained CR (OR 22.286, 95% CI 2.742-132.717, p=0.001). Overall adverse events reported in 18 patients (18/80, 23.3%), including 3 serious infection (pulmonary tuberculosis and herpes zoster). CONCLUSIONS: Treatment with IFX was efficacious and relatively safe for refractory CD patients in Korea. An initial CR at 10 weeks was significantly associated with sustained CR.

ABSTRACT

BACKGROUND/AIMS: The aim of this study was to investigate outcomes and current status of the National Liver Cancer Screening Program in a single healthcare center. METHODS: Subjects received abdominal ultrasonography (US) and/or serum alpha-fetoprotein (AFP) testing from January 2011 to December 2012. The clinical characteristics of the subjects, detection rate of liver cancer, and direct medical costs were investigated. RESULTS: Among 621 subjects, five (0.8%) were newly detected with hepatocellular carcinoma. Four underwent curative treatment, and all were detected by US (two surgical resections and two radiofrequency ablations). The remaining patient, whose disease was detected by an elevated AFP level, was infiltrative type with a poor prognosis. Of 492 subjects whose medical history was revealed, 45% had hepatitis B, 5% had hepatitis C, 1% had both, and 3% had other liver cirrhosis including alcoholic cirrhosis. The remaining 46% of subjects had no risk factors for liver cancer. Direct medical costs were estimated at 8,420,000 Won for detecting a single case of liver cancer, which was much lower than that of stomach cancer at 45,060,000 Won. If the non-high risk subjects were excluded, the cost for a single case of liver cancer decreased to 5,560,000 Won. CONCLUSIONS: The high-risk group should be more accurately defined by appropriate screening tests to optimize liver cancer surveillance. The detection rate by the liver cancer surveillance program was about 1%, and most tumors could be detected at the early stage by US. The role of AFP seemed to be small for early defection of liver cancer.

ABSTRACT

BACKGROUND/AIMS: Some clinical and laboratory parameter are predictors to determine steroid treatment failure in patients acute severe ulcerative colitis. We aimed to validate previous models in the Korean patients. METHODS: This study was conducted retrospectively with 70 patients who were diagnosed with severe ulcerative colitis (UC) between January 2001 and June 2011. The rate of treatment failure was investigated using predictors or numerical scoring systems from prior studies. RESULTS: Twelve (17.2%) patients failed to respond to steroid therapy. The logistic regression analysis revealed that stool frequency on the fifth day and colonic dilatation were the only independent predictive factors related to treatment failure. Formulated numerical risk scores based on mean stool frequency, colonic dilatation, and hypoalbuminemia were significantly higher in the non-responding group than those in the responding group (P8 than in the group with a score 8 plus CRP >4.5 mg/dL or bloody stool plus CRP >4.3 mg/dL) than those of the other group at the third day (40% vs. 7.3%, P=0.004; 33.3% vs. 5.2%, P=0.014, respectively). CONCLUSIONS: Stool frequency and CRP level were the meaningful parameters among the predictors for steroid treatment response. Furthermore, several predictive models for steroid treatment failure in western countries seem to be of value for use in the Korean population.

ABSTRACT

PURPOSE: To compare clinical and radiological results between closed reduction followed by percutaneous K-wire fixation and volar locking compression plate fixation in the treatment of AO type-C1, 2 fractures of the distal radius. MATERIALS AND METHODS: The subjects of this study were 61 patients who had a AO type-C1,2 fracture of the distal radius treated from March 2006 to January 2010, and were followed up for over 12 months. Clinical evaluations included disabilities of arm, shoulder and hand score (DASH) score, patient-rated wrist evaluation questionnaires (PRWE) score, the Grip strength, and the range of joint motion at the last follow-up, and radiological assessment included the presence of bony union, the dorsal tilt angle of the radius, the inclination of the radius, and the radial shortening. RESULTS: The range of joint motion, the grip strength, DASH and PRWE demonstrated no significant difference between the two groups. Radiological results revealed that the patients treated with percutaneous K-wire fixation showed greater radial shortening than those treated with locking compression plate fixation. CONCLUSION: Although clinical results are similar between volar locking plating and percutaneous pinning in the treatment of AO C1, 2 distal radius fractures, volar locking plating is more effective in preventing radial shortening during fracture healing.

ABSTRACT

In recent years, Acinetobacter baumannii has become an increasingly common nosocomial pathogen. It causes rare, but severe, central nervous system (CNS) infection, especially in patients undergoing neurosurgical procedures or with head trauma. Multi-drug-resistant A. baumannii (MDR-AB) has emerged as a pathogen causing CNS infection. We describe A. baumannii CNS infections seen during the last 5 years and focus on MDR-AB CNS infection. Seven patients were admitted to the neurosurgical intensive care unit with serious head injuries. Imipenem-susceptible A. baumannii was identified in all four cases seen from 2003 to 2006, whereas the three cases seen from 2007 to 2008 were MDR-AB CNS infections. Two cases of MDR-AB CNS infection were cured with intraventricular or intrathecal colistin without any side effects. Therefore, intraventricular or intrathecal colistin should be considered for MDR-AB CNS infection. Studies of the dose and duration of intraventricular and intrathecal administration are needed.

ABSTRACT

A 55-year-old man underwent a posterior decompression and fusion under general anesthesia. Near the end of the operation, the pressure waveform from the radial artery became flat, and his oxygen level could not be measured using pulse oximetry. Palpation of the carotid artery revealed no heart rate, and ventricular asystole was diagnosed. The patient was given cardiovascular drugs, but his hemodynamic status deteriorated, leading to severe hypotension, with sinus bradycardia, sinus tachycardia, sinus arrest, and paroxysmal supraventricular tachycardia. The patient had hypothermia based on an axillary temperature of 31.9degrees C. After active warming, his cardiovascular status stabilized.

ABSTRACT

OBJECTIVES: This study examined the use of health impact assessment (HIA) as a tool for intersectoral collaboration using the case of an HIA project conducted in Gwang Myeong City, Korea. METHODS: A typical procedure for rapid HIA was used. In the screening step, the Aegi-Neung Waterside Park Plan was chosen as the target of the HIA. In the scoping step, the specific methods and tools to assess potential health impacts were chosen. A participatory workshop was held in the assessment step. Various interest groups, including the Department of Parks and Greenspace, the Department of Culture and Sports, the Department of Environment and Cleansing, civil societies, and residents, discussed previously reviewed literature on the potential health impacts of the Aegi-Neung Waterside Park Plan. RESULTS: Potential health impacts and inequality issues were elicited from the workshop, and measures to maximize positive health impacts and minimize negative health impacts were recommended.
