ABSTRACT

Objective@#This study aimed to investigate the impact of baseline values and temporal changes in body composition parameters, including skeletal muscle index (SMI) and visceral adipose tissue area (VAT), measured using serial computed tomography (CT) imaging on the prognosis of operable breast cancers in Asian patients. @*Materials and Methods@#This study retrospectively included 627 Asian female (mean age ± standard deviation [SD], 53.6 ± 8.3 years) who underwent surgery for stage I–III breast cancer between January 2011 and September 2012. Body composition parameters, including SMI and VAT, were semi-automatically calculated on baseline abdominal CT at the time of diagnosis and follow-up CT for post-treatment surveillance. Serial changes in SMI and VAT were calculated as the delta values. Multivariable Cox regression analysis was used to evaluate the association of baseline and delta SMI and VAT values with disease-free survival. @*Results@#Among 627 patients, 56 patients (9.2%) had breast cancer recurrence after a median of 40.5 months. The mean value ± SD of the baseline SMI and baseline VAT were 43.7 ± 5.8 cm2 /m2 and 72.0 ± 46.0 cm2 , respectively. The mean value of the delta SMI was -0.9 cm2 /m2 and the delta VAT was 0.5 cm2 . The baseline SMI and VAT were not significantly associated with disease-free survival (adjusted hazard ratio [HR], 0.983; 95% confidence interval [CI], 0.937–1.031; p = 0.475 and adjusted HR, 1.001; 95% CI, 0.995–1.006; p = 0.751, respectively). The delta SMI and VAT were also not significantly associated with disease-free survival (adjusted HR, 0.894; 95% CI, 0.766–1.043; p = 0.155 and adjusted HR, 1.001; 95% CI, 0.989–1.014; p = 0.848, respectively). @*Conclusion@#Our study revealed that baseline and early temporal changes in SMI and VAT were not independent prognostic factors regarding disease-free survival in Asian patients undergoing surgery for breast cancer.

ABSTRACT

Background@#The purpose of this study was to evaluate the clinical and radiologic outcomes of reverse total shoulder arthroplasty (RTSA) using a small glenoid baseplate in patients with a small glenoid and to analyze the contributing factors to scapular notching. @*Methods@#A total of 71 RTSAs performed using a 25-mm baseplate were evaluated at a mean of 37.0 ± 3.3 months. Shoulder function was evaluated using American Shoulder and Elbow Surgeons (ASES) score, visual analog scale (VAS) for pain, Single Assessment Numeric Evaluation (SANE) for satisfaction, and active range of motion. Scapular neck angle (SNA), prosthesis-scapular neck angle (PSNA), peg glenoid rim distance (PGRD), and sphere bone overhang distance (SBOD) were measured to assess the effects on scapular notching. @*Results@#Shoulder function (ASES: 39.4 ± 13.8 preoperative vs. 76.2 ± 9.5 at last follow-up, p< 0.001), VAS for pain (6.1 ± 1.8 vs. 1.7 ± 1.4, p < 0.001), SANE for satisfaction (7.0 ± 11.8 vs. 83.4 ± 15.3, p < 0.001), and active forward flexion (115.6° ± 40.1° vs. 141.6° ± 17.2°, p< 0.001) were significantly improved. The mean diameter of the inferior glenoid circle was 26.0 ± 3.0 mm and the mean glenoid vault depth was 24.0 ± 4.5 mm. Scapular notching was found in 13 patients (18.3%) and acromial fracture in 2 patients (2.8%). There were no significant differences in preoperative SNA and PSNA at postoperative 3 years between patients with and without scapular notching (101.6° ± 10.5° and 110.8° ± 14.9° vs. 97.3° ± 13.3° and 104.9° ± 12.4°; p = 0.274 and p= 0.142, respectively). PGRD and SBOD were significantly different between patients with scapular notching and without scapular notching (24.8 ± 1.6 mm and 2.6 ± 0.5 mm vs. 21.9 ± 1.9 mm and 5.8 ± 1.9 mm; p < 0.001 and p < 0.001, respectively). @*Conclusions@#RTSA using a 25-mm baseplate in a Korean population who had relatively small glenoids demonstrated low complication rates and significantly improved clinical outcomes. Scapular notching can be prevented by proper positioning of the baseplate and glenosphere overhang using size-matched glenoid baseplates.

ABSTRACT

OBJECTIVE@#To study the risk factors and treatment for neutropenia of late newborns (NLN).@*METHODS@#Related clinical data were collected from the preterm infants and critically ill neonates who were admitted to the neonatal intensive care unit from July 2019 to January 2020. A total of 46 newborns with a blood absolute neutrophil count (ANC) of 37 weeks. There was no significant difference between the two groups in the incidence rates of gestational hypertension, premature rupture of membranes > 18 hours and intrauterine distress, 5-minute Apgar score, the duration of positive pressure ventilation, the incidence rate of early-onset sepsis, and the type of initially used antibiotics (@*CONCLUSIONS@#The risk of NLN increases with the presence of late-onset sepsis and the increase in the duration of antibiotic use. NLN is generally a benign process. G-CSF appears to be safe and effective for NLN with severe disease conditions or severe reduction in ANC.

ABSTRACT

We aimed to assess the effect of plate hook bending in treatment of acromioclavicular (AC) dislocation by analyzing clinical and radiological results according to the angle of the plate hook (APH). Methods: This was a retrospective, observational, case-control study including 76 patients with acute AC joint dislocation that were divided into two groups according to treatment with bent or unbent plate hook. The visual analog scale (VAS), the American Shoulder and Elbow Surgeons (ASES) shoulder score, and range of motion (ROM) were evaluated as clinical outcomes. Comparative coracoclavicular distance (CCD) was measured to evaluate radiological outcomes. Results: While the VAS and ASES of the bending group at 4 months after surgery were significantly higher (p=0.021 and p=0.019), the VAS and ASES of the bending group at other periods and ROM of the bending group showed no significant difference. The initial CCD decreased from 183.2%±25.4% to 114.3%±18.9% at the final follow-up in the bending group and decreased from 188.2%±34.4% to 119.1%±16.7% in the non-bending group, with no statistical difference (p=0.613). The changes between the initial and post-metal removal CCD were 60.2%±11.2% and 57.3%±10.4%, respectively, with no statistical difference (p=0.241). The non-bending group showed greater subacromial osteolysis (odds ratio, 3.87). Pearson’s coefficients for the correlation between APH and VAS at 4 months after surgery and for that between APH and ASES at 4 months after surgery were 0.74 and –0.63 (p=0.027 and p=0.032), respectively. Conclusions: The APH was associated with improved postoperative pain and clinical outcomes before implant removal and with reduced complications; therefore, plate hook bending is more useful clinically during plate implantation.

ABSTRACT

Objective:To investigate the role of polyomavirus enhancer activator 3 (PEA3) in hyperoxia-induced injury of type Ⅱ alveolar epithelial cells (AEC Ⅱ) and the underlying mechanism.Methods:AEC Ⅱ cells were cultured in vitro and divided into hyperoxia group and normoxia group.After 24 h, 48 h and 72 h of hyperoxia or air treatment, cells were collected and the best treatment time was selected at 48 h. AEC Ⅱ cells were divided into 3 groups: control group, negative control group (transfected with negative control) and PEA3 over expression group (transfected with PEA3 overexpression plasmid). Each group was further divided into hyperoxia subgroup and normoxia subgroup.Cells were harvested at 48 h after hyperoxia or normoxia treatment.Reactive oxygen species (ROS), Nod-like receptor domain 3 (NLRP3), monocyte chemoattractant protein-1 (MCP-1), interleukin(IL)-1β, IL-6, IL-8, IL-18, surfactant protein C (SP-C), aquaporins 5 (AQP5), PEA3 and manganese superoxide dismutase (MnSOD) levels were detected.Differences were compared by the t-test and repeated measures analysis of variance using SPSS 20.0 statistical software. Results:The interaction of grouping and treatment duration had significant effects on ROS, IL-1β, IL-6, IL-8, IL-18, SP-C and AQP5 levels in AEC Ⅱ cells ( F=19.857, 20.132, 23.133, 18.673, 28.341, 27.333 and 34.217, respectively, all P<0.05). At 24 h, 48 h and 72 h, ROS level in hyperoxia group was 1.78, 1.94 and 2.26 times higher than that in normoxia group ( t=18.649, 17.486 and 19.385, respectively all P<0.05). NLRP3 and MCP-1 levels were significantly upregulated in hyperoxia group.IL-1β level was 1.33, 1.69, and 1.65 times higher in hypoxia group at 24 h, 48 h and 72 h than that of normoxia group; IL-6 level was 1.26, 1.56 and 2.12 timers higher; IL-8 level was 1.13, 1.47 and 2.34 times higher; and IL-18 level was 1.46, 1.72 and 1.95 times higher, respectively (all P<0.05). The protein expression of SP-C was downregulated, while that of AQP5 was significantly upregulated in hypoxia group.The RNA expression of SP-C was 22%, 63% and 72% lower in hypoxia group than that in normoxia group at 24 h, 48 h and 72 h ( t=3.982, 16.328 and 20.259, P<0.05, respectively), and that of AQP5 was 1.92, 5.23 and 7.36 times higher ( t=14.631, 18.945 and 19.521, respectively, all P<0.05). There were significant differences in ROS, IL-1β, IL-6, IL-8, IL-18, SP-C and AQP5 levels at 24 h, 48 h and 72 h in hyperoxia group ( F=22.343, 20.566, 23.701, 19.222, 32.146, 40.278 and 37.107, respectively, all P<0.05). After 48 h of PEA3 overexpression, compared with the hyperoxic negative control group, ROS level in hyperoxic AEC Ⅱ cells overexpressing PEA3 decreased by 34% ( t=14.635, P<0.05). NLRP3 and MCP-1 were downregulated in hyperoxic AEC Ⅱ cells after overexpression of PEA3.IL-1β, IL-6, IL-8 and IL-18 levels decreased by 29%, 22%, 27% and 18%, respectively ( t=15.895, 17.872, 18.749 and 15.274, all P=0.000). SP-C was upre-gulated and AQP5 was downregulated by overexpression of PEA3 in hyperoxic AEC Ⅱ cells.In addition, PEA3 and MnSOD levels were significantly enhanced. Conclusions:Overexpression of PEA3 can alleviate the increase of ROS level in AEC Ⅱ cells, block the activation of various inflammatory pathways and reduce the transformation from AEC Ⅱ to AEC Ⅰ cells via enhancing MnSOD level.

ABSTRACT

Objective:To evaluate the correlation, consistency and safety of an smartphone application (APP) in screening neonatal jaundice using the smartphone based on the image-based bilirubin (IBB) and transcutaneous bilirubin (TcB).Methods:From July to October 2018, neonates with the age ≤28 d and gestational age ≥35 weeks who were admitted to Department of Neonatal and Obstetrics, Xuzhou Central Hospital without blue light phototherapy were recruited.They were randomly divided into two groups to measure the jaundice value of skin in front of sternum by a cross-control analysis.Jaundice level in group Ⅰ was first measured using the Nezhabaobei? APP in iPhone 6, and then measured using the JM-103 transcutaneous jaundice instrument as the control device.In group Ⅱ, jaundice level was sequencially measured by the control device and the Nezhabaobei? APP.Sex, age, gestational age, birth weight and the mean value of three consecutive tests were recorded.The Pearson′s correlation analysis, Bland-Altman plots consistency analysis, t test and receiver operating characteristic (ROC) curve were used for statistical analysis. Results:A total of 185 eligible neonates were enrolled, including 99 males and 86 females, with the median age of 5 d (3-8 d), gestational age of (37.6 ± 1.7) weeks, and birth weight of (2 950 ± 645) g. There were good correlation ( r=0.860, P<0.05) and consistency (95.1% of the samples fall within the 95% consistency interval) between IBB and TcB.Good correlation and consistency were also yielded in subgroup analyses based on the sex, age, gestational age and birth weight.The consistency was better in subgroups of ≤7 d, >37 weeks and>2 500 g. The ability of IBB to predict TcB>256.5 μmol/L was better than that of TcB>171.0 μmol/L.The area under the ROC curve was 0.93, the cut-off value was 232.6 μmol/L, the sensitivity was 96.7%, and the specificity was 82.6%.The difference of the mean values of IBB and TcB detected for 3 times was significantly lower than that obtained in the first measurement of IBB and TcB [(12.0 ± 34.4) μmol/L vs.(14.4 ± 38.6) μmol/L, P=0.038]. There were no adverse events and no defects in the device itself. Conclusions:There are good correlation and consistency between IBB and TcB.The ability of IBB to predict TcB>256.5 μmol/L is better than that of TcB>171.0 μmol/L, which is safe in clinical use.

ABSTRACT

Objective:To explore the effect of chemical compound of aconitum alkaloid on the lipopolysaccharide (LPS)-induced inflammatory response of RAW264.7 macrophages and investigate its mechanism. Method:The chemical compounds of Aconitum Kusnezoffii Reichb were collected from TCMSP database with consideration of oral bioavailability (OB)≥30% and drug-likeness (DL)≥0.18. The potential targets of each chemical component were predicted with use of Pubchem database and Swiss Target Prediction database. Rheumatoid arthritis (RA) targets were collected from GeneCards database and selected by intersection screening. Gene ontology (GO) classification enrichment and Pathway enrichment analysis were carried out with use of DAVID database. Cytoscape was used to construct "Chemical Compound-Potential Targets-Pathway-Disease" network. Protein-protein interaction (PPI) network was constructed by using STRING database and Cytoscape software. RAW264.7 macrophages were stimulated by LPS to establish macrophage inflammation model <italic>in vitro</italic>. Western blot was used to detect the effects of chemical compounds on the expression of tumor necrosis factor-<italic>α</italic> (TNF-<italic>α</italic>) and cyclooxygenase-2 (COX-2) in RAW264.7 cells induced by LPS, as well as on the expression of JAK kinase and nuclear transcription factor- kappa B (NF-<italic>κ</italic>B) signal pathway. Result:A total of 27 chemical compounds were obtained by searching TCMSP database and consulting literature (OB≥30%, DL≥0.18). 12 chemical compounds were obtained after screening. 177 potential targets were obtained after database prediction and screening, and 97 targets were obtained as potential targets for the treatment of RA after intersection between 177 potential targets and 4 329 RA targets. A total of 32 biological processes (BP), 5 cellular components (CC), and 12 molecular functions (MF) were enriched by DAVID database. The construction of network topology map showed that different chemical compounds can act on the same target and the same chemical compound can also act on different targets in the treatment of RA. Aconitum alkaloid can be connected with the same pathway through different targets or with different pathways through the same target, indicating that different targets may have synergistic effect, which fully reflected the complex multi-compound, multi-targets and multi-pathways mechanism. Different concentrations of LPS in stimulation (0-200 μg·L<sup>-1</sup>) can significantly up-regulate the expression of COX-2 protein in RAW264.7 macrophages (<italic>P</italic><0.05), indicating that the inflammatory model was successful. Compared with the normal group, the expression of TNF-<italic>α</italic> and COX-2 protein in the inflammatory model of RAW264.7 cells increased significantly(<italic>P</italic><0.05), while the expression of TNF-<italic>α</italic> and COX-2 protein in bulleyaconitine A(BLA), songorine, yunaconitine and karacoline groups decreased in varying degrees compared with the model group (<italic>P</italic><0.05). Compared with the normal group, the expression of IRAK4, NF-<italic>κ</italic>B, JAK1 and STAT3 in the inflammatory model of RAW264.7 cells were significantly increased (<italic>P</italic><0.05), while such levels in BulleyaconitineA, songorine, yunaconitine and Karacoline groups were significantly lower than those in the model group(<italic>P</italic><0.05). Conclusion:Based on systematic pharmacology and <italic>in vitro</italic> experiments, the related targets and signal pathways were analyzed to provide new insights into the pathogenesis of RA, reveal the molecular mechanism of aconitum alkaloid in the treatment of RA, and provide new ideas for the application of Mongolian medicine in modern medicine.

ABSTRACT

Purpose@#This study examined whether mirror therapy could improve the balance, gait, and motor function of patients with subacute stroke. @*Methods@#Thirty-three patients with subacute stroke were divided randomly into three groups: experimental group1, experimental group2, and the control group. The patients in experimental group1 performed a mirror therapy program on the unaffected side of the lower extremities, and the patients in experimental group2 performed mirror therapy on the affected side of the lower extremities. Both groups performed the exercise for 30 minutes per session, five times a week for four weeks. The control group did not receive mirror therapy. BBS, POMA, 10MWT, and the BRS were used to evaluate the balance, the quality of gait, gait speed, and the motor function before and after the intervention. @*Results@#The gait speed increased significantly in the experimental groups1 and 2 after the intervention. The control group showed no significant difference in the gait speed after the intervention. The change in gait speed before and after the intervention showed a significant difference among the groups. Experimental group1 showed a significant increase in the gait speed compared to that of the control group. @*Conclusion@#This study suggests that mirror therapy could be an effective intervention to improve the gait speed of patients with subacute stroke. On the other hand, there was no difference in the effectiveness of mirror therapy and therapeutic exercise on the balance, gait, and motor function.

ABSTRACT

Purpose@#The purpose of this study was to analyze research trends and find whether Post-Traumatic Stress Disorder (PTSD) of refugees could affect structural or functional changes of brains of those under MRI, focusing on volumes, functional connectivities, and metabolites. @*Methods@#A literature search was done using PubMed, Embase, RISS, and KMBase to identify studies that matched our research purpose. A total of eight studies were identified using Prisma flow diagram by two reviewers independently. @*Results@#Eight studies were identified. Three studies were on North Korean defectors as subjects. The number of studies that observed structural changes, functional changes, and metabolite changes in brains was 2, 5, and 2, respectively. Although each study observed various parts of the brain, anterior cingulate cortex (ACC) was observed commonly in three studies. The PTSD group showed reduction of ACC volume and N-acetyl-aspartate (NAA) metabolite in ACC compared to the non- PTSD group. When exposed to negative stimuli, the PTSD group showed higher neural activity than the non-PTSD group, but not vice versa. @*Conclusion@#ACC showed significant difference in volume, neural activity, and NAA metabolite between the PTSD and the non-PTSD group, resulting in significant differences in structural changes, functional changes, metabolite changes, respectively. This study showed the need for conducting more research using various biomarkers to clarify the relationship between PTSD of refugees and their brain changes.

ABSTRACT

OBJECTIVES@#This work aimed to evaluate the ability of two kinds of antioxidants, namely, grape-seed extract and sodium ascorbate, in restoring bond strength at the resin-enamel interface after bleaching.@*METHODS@#Ten groups of samples with 15 teeth per group were prepared for shear-bond-strength test at the resin-enamel interface after bleaching. The groups were as follows: control; no antioxidant; 2.5%, 5%, 10%, or 15% grape-seed extract; and 2.5%, 5%, 10%, or 15% sodium ascorbate. The peak values of shear bond strength when resin was debonded from teeth and the failure modes under a microscope were recorded. Ten other groups of teeth with two teeth per group were prepared and treated in a similar approach before resin bonding. The samples were cut vertically to the bonding interface. The structures of the bonding interface were compared by scanning electron microscopy.@*RESULTS@#No statistically significant difference in shear bond strength was found among the no-antioxidant, 2.5% grape-seed extract, and 2.5%, 5%, or 10% sodium ascorbate groups (@*CONCLUSIONS@#Immediately after bleaching, the bond strength of dental enamel significantly decreased. Bond strength can be restored by 5% grape-seed extract or 15% sodium ascorbate in 5 min.

ABSTRACT

Objective:To observe the effect of combining transcranial direct current stimulation (tDCS) with functional electrical stimulation-assisted cycling (FES-cycling) on lower limb motor function early after a stroke.Methods:Thirty-seven survivors of a recent stroke were divided into a tDCS treatment group ( n=18) and a pseudo-stimulation group ( n=19). While receiving routine rehabilitation training and clinical drug treatment, the tDCS treatment group also cycled in response to functional electrical stimulation while simultaneously receiving tDCS anode stimulation of the motor cortex M1 area. The pseudo-stimulation group followed the same protocol but with the tDCS stimulation inactivated. Both groups were treated for 20min daily, 5 days weekly for 4 weeks. Before and after the 4 weeks of treatment, the lower limb motor function, walking ability and ability in the activities of daily living of both groups were evaluated using the Fugl-Meyer assessment scale for the lower extremities (FMA-LE), the timed up and go test (TUGT) and the modified Barthel index (MBI) respectively. Transcranial magnetic stimulation was used to detect each subject′s cerebral cortex motor threshold (CMT) , cortical latency (CL) and central motor conduction time (CMCT) as well as the amplitude (Amp) of the motor evoked potential of the lower limb primary motor cortex (M1 area). Results:After 4 weeks of treatment, the average FMA-LE and MBI scores and TUGT times of the two groups had improved significantly compared with those before treatment. The average FMA-LE score and TUGT time of the tDCS group were significantly better than those of the pseudo-stimulation group. The average CMT, CL and CMCT in both groups were significantly lower than those before the intervention, while the average Amp had increased significantly, but there were significant differences in the average CMT, Amp, CL and CMCT between the two groups after the 4 weeks of treatment.Conclusions:Transcranial direct current stimulation combined with cycling assisted by functional electrical stimulation can effectively stimulate excitability in the motor cortex soon after a stroke. That should promote the recovery of nerve activity and lower limb function.

ABSTRACT

Background and Objectives@#Polylactic-co-glycolic acid (PLGA) plate has been recognized for its biocompatibility and biomechanical properties and used widely in various clinical fields. The aim of this study was to evaluate the usefulness and reliability of PLGA plate as a graft material in septorhinoplasty.Subjects and Method Medical records were retrospectively analyzed for patients who underwent septorhinoplasty including extracorporeal septoplasty from January 2017 to June 2020. We evaluated demographics, diagnosis, operation techniques, and complications of PLGA plate as a graft material used in these patients. @*Results@#A total of 33 patients were enrolled in this study. Twenty-eight were male and 5 were female. The median age was 32 years old. The follow-up period after surgery was 6-32 months, and the mean follow-up period was 18.03 months. The PLGA plate was used in unilateral spreader graft (n=17), bilateral spreader graft (n=10), batten graft (n=3), strengthening of septal extension graft (n=2) and columellar strut graft (n=3), and fixing L-strut during extracorporeal septoplasty (n=12). During the follow-up period, no patient experienced extrusion or exposure of the grafts. Mild complications, such as redness of the columella skin, granulation in the marginal incision site, and pain on the nasal dorsum were observed in three patients; these complications were temporary and patients improved with conservative treatments. @*Conclusion@#The PLGA plate may be a useful graft material in correcting deviated nose especially when the harvested septal cartilage is insufficient and if used carefully in limited locations such as L-strut and columella.

ABSTRACT

BACKGROUND/OBJECTIVES@#Obesity is associated with the impaired regulation of T cells characterized by increased numbers of Th1 and Th17 cells and the dysregulation of vitamin D metabolism. Both obesity and vitamin D have been reported to affect autophagy; however, a limited number of studies have investigated the effects of vitamin D on T cell autophagy in obese mice. Therefore, we aimed to determine whether in vitro treatment with vitamin D affects the proliferation, function, and autophagy of T cells from obese and control mice.MATERIALS/METHODS: Five-week-old male C57BL/6 mice were fed control or high-fat diets (10% or 45% kcal fat: CON or HFDs, respectively) for 12 weeks. Purified T cells were stimulated with anti-CD3 and anti-CD28 monoclonal antibodies and cultured with either 10 nM 1,25(OH)2D3 or 0.1% ethanol (vehicle control). The proliferative response; expression of CD25, Foxp3, RORγt, and autophagy-related proteins (LC3A/B, SQSTM1/P62, BECLIN-1, ATG12); and the production of interferon (IFN)-γ, interleukin (IL)-4, IL-17A, and IL-10 by T cells were measured. @*RESULTS@#Compared with the CON group, T cell proliferation tended to be lower, and the production of IFN-γ was higher in the HFD group. IL-17A production was reduced by 1,25(OH)2D3 treatment in both groups. The LC3 II/I ratio was higher in the HFD group than the CON group, but P62 did not differ. We observed no effect of vitamin D treatment on T cell autophagy. @*CONCLUSIONS@#Our findings suggest that diet-induced obesity may impair the function and inhibit autophagy of T cells, possibly leading to the dysregulation of T cell homeostasis, which may be behind the aggravation of inflammation commonly observed in obesity.

ABSTRACT

Purpose@#This retrospective study was aimed to evaluate the clinical characteristics and treatment outcomes in patients with osteonecrosis of the jaw who were receiving oral versus intravenous (IV) bisphosphonate (BP). @*Materials and methods@#This retrospective study enrolled subjects who had been diagnosed with medicationrelated osteonecrosis of the jaw (MRONJ) during the period from July 2010 to June 2014. Information regarding the following demographic and clinical characteristics was collected: demographic data, administration route and type of BP, duration of BP medication, primary disease, number of involved sites, location of the lesion, number of surgeries, outcome of treatments, and laboratory test. All the patients were divided into oral and IV BP groups; and the between-group differences were compared. @*Results@#Total 278 patients were divided into two groups as per the route of BP administration. The proportion of oral BP-related MRONJ group were more dominant over IV BP group (oral BP, n = 251; IV BP, n = 27). In the IV BP group, the average dosing duration (31.4 months) was significantly shorter than that in the oral BP group (53.1 months) (P < 0.001). The average number of involved sites in the oral BP group (1.21 ± 0.48) was smaller than that in the IV BP group (1.63 ± 0.84) (P < 0.001). The average number of surgeries was higher in the IV BP group (1.65 ± 0.95) as compared to that in the oral BP group (0.98 ± 0.73) (P < 0.001). Outcome after the surgery for MRONJ after IV BP was poor than oral BP group. @*Conclusion@#IV administration of BP causes greater inhibition of bone remodeling and could lead more severe inflammation. Therefore, even if the duration of IV administration of BP is shorter than that of oral BP, the extent of the lesion could be more extensive. Therefore, the result suggests that the MRONJ after IV BP for cancer patients needs to be considered as different characteristics to oral BP group for osteoporosis patents.

ABSTRACT

Background/Aims@#There has been growing evidence on the utility of neoadjuvant FOLFIRINOX in borderline resectable (BR) or locally advanced (LA) pancreatic cancer. However, factors predicting survival in these patients remain to be identified, and we aimed to identify these prognostic factors. @*Methods@#Between January 2013 and April 2017, patients with BR or LA pancreatic cancer who received FOLFIRINOX as their initial treatment were identified. Demographic data and clinical outcomes, including the chemotherapy response, conversion to resection, and survival, were reviewed. @*Results@#A total of 117 patients with BR (n=39) or LA (n=78) pancreatic cancer were included. Of these patients, 29 (24.8%) underwent curative surgery, and R0 resection was achieved in 21 patients (72.4%). The median progression-free survival and overall survival time of all patients were 11.6 and 19.0 months, respectively. In resected patients, the median relapse-free survival and overall survival times were 14.8 and 28.6 months, respectively. In the multivariate Cox model, the lowest level of serum carbohydrate antigen 19-9 (CA 19-9) and resection after FOLFIRINOX were independent factors for improved overall survival. In the subgroup analysis of patients with initial 18 F-fluorodeoxyglucose-positron emission tomography (FDG-PET) images, the maximum standardized uptake value (SUVmax) of the pancreatic mass was also shown as an independent factor for improved overall survival. @*Conclusions@#In patients with BR or LA pancreatic cancer, FOLFIRINOX is a valuable neoadjuvant treatment that enables curative surgery in approximately one-quarter of patients and significantly improves overall survival. In these patients, the prognosis can be estimated using the lowest level of serum CA 19-9, operative status, and initial FDG-PET SUVmax.
