Abstract
It has been 30 years since Photofrin-PDT was approved for the treatment of bladder cancer in Canada. However, Photofrin-PDT failed to gain popularity due to bladder complications. The PDT with red light and IV-administered Photofrin could permanently damage the bladder muscle. We have been developing a new combination strategy of PpIX-PDT with singlet oxygen-cleavable prodrugs for NMIBC with minimal side effects, avoiding damage to the bladder muscle layer. PpIX can be excited by either green (532 nm) or red (635 nm) light. Red light could be more efficacious in vivo due to its deeper tissue penetration than green light. Since HAL preferentially produces PpIX in tumors, we hypothesized that illuminating PpIX with red light might spare the muscle layer. PpIX-PDT was used to compare green and red laser efficacy in vitro and in vivo. The IC50 of in vitro PpIX-PDT was 18 mW/cm2 with the red laser and 22 mW/cm2 with the green laser. The in vivo efficacy of the red laser with 50, 75, and 100 mW total dose was similar to the same dose of green laser in reducing tumor volume. Combining PpIX-PDT with prodrugs methyl-linked mitomycin C (Mt-L-MMC) and rhodamine-linked SN-38 (Rh-L-SN-38) significantly improved efficacy (tumor volume comparison). PpIX-PDT or PpIX-PDT + prodrug combination did not cause muscle damage in histological analysis. Overall, a combination of PpIX-PDT and prodrug with 635 nm laser is promising for non-muscle invasive bladder cancer treatment.

Abstract
Mitochondria play an essential role in cancer treatment by providing apoptotic signals. Hexyl aminolevulinate, an FDA-approved diagnosis for non-muscle invasive bladder cancer, induces the production of protoporphyrin IX (PpIX) preferentially by mitochondria in cancer cells. Photosensitizer PpIX upon illumination can release active chemotherapy drugs from singlet oxygen-activatable prodrugs. Prodrugs placed close enough to PpIX formed in mitochondria can improve the antitumor efficiency of PpIX-PDT. The preferred uptake of prodrugs by cancer cells and tumors can further enhance the selective damage of cancer cells over non-cancer cells and surrounding normal tissues. Mitochondriotropic prodrugs of anticancer drugs, such as paclitaxel and SN-38, were synthesized using rhodamine, a mitochondrial-targeting moiety. In vitro, the mitochondrial targeting helped achieve preferential cellular uptake in cancer cells. In RT112 cells (human bladder cancer cells), intracellular prodrug concentrations were 2-3 times higher than the intracellular prodrug concentrations in BdEC cells (human bladder epithelial cells), after 2 h incubation. In an orthotopic rat bladder tumor model, mitochondria-targeted prodrugs achieved as much as 34 times higher prodrug diffusion in the tumor area compared to the nontumor bladder area. Overall, mitochondria targeting made prodrugs more effective in targeting cancer cells and tumors over non-tumor areas, thereby reducing nonspecific toxicity.

Abstract
INTRODUCTION Dental caries remains one of the most prevalent but preventable diseases among children worldwide and especially affects children with a lower socioeconomic status or ethnic minority background. It is important that all groups of children are reached by preventive interventions to reduce oral health inequalities. So far, it is unknown whether children from different social and ethnic groups benefit equally from potentially effective oral health interventions. OBJECTIVES This scoping review aimed to identify European public health interventions that report their effect on dental caries across different social groups. METHODS Four databases were searched for studies evaluating the effect of oral health interventions on dental caries among children from 0 to 12 y, and studies were included when results were presented by children of different social groups separately. RESULTS A total of 14 studies were included, representing 4 different countries: 3 randomized and 11 nonrandomized studies. Most studies were performed at schools. Six studies showed results indicative of a reduction in oral health inequalities, 4 studies showed results that potentially widen oral health inequalities, and 5 studies showed results that were indicative of no impact on oral health inequalities. Interventions that contain early approaches, with a high frequency, approaching multiple levels of influence, and including at least the broader organizational or public policy level, may have the potential to reduce oral health inequalities among children from birth to young adolescence. CONCLUSION We recommend researchers to perform high-quality intervention studies and to evaluate the effectiveness of oral health intervention always in different socioeconomic or ethnic groups separately, to better understand their contribution toward oral health (in)equalities. KNOWLEDGE TRANSFER STATEMENT This review offers insight in the differential effects that oral health interventions might have across different social groups. Its results can be used to develop interventions that might reduce oral health inequalities among children. Also, we recommend future researchers to always evaluate the effects of any preventive oral health measure in different social groups separately.

Abstract
PURPOSE/OBJECTIVE(S) Palliative management of large, symptomatic pulmonary lesions, either as primary lung cancers or metastases, can be challenging due to need to balance effective radiation doses for cytoreduction with safety. Spatially Fractionated Radiation Therapy (SFRT), or GRID Therapy, is an emerging technique, which delivers ablative doses of radiotherapy to small, selected areas of tumor, while sparing organs-at-risk (OARs), and has been shown to debulk large lesions in preliminary studies. Conventionally, an alloy GRID block is manufactured to deliver GRID therapy. However, this delivery technique poses a challenge due to need for block, and dosimetrically when the tumor is deep-seated as excess dose may be delivered to OARs, such as skin and chest wall. This study aims to develop a fast, automatic planning solution using multi-focal dynamic conformal arcs (DCA) on modern Linear Accelerator. MATERIALS/METHODS One late-stage lung cancer patient with simulated sphere target grid was included in this study. The sphere targets are 1.5cm in diameter and 4.3cm spacing. Four co-planar full arcs were used for optimization. The problem is formalized as finding optimal multi-leaf collimator (MLC) sequencing to cover N targets with K control points (CPs) for each arc. The state of each target's MLC opening at each CP is binary. In order to solve this NP-hard problem, the optimal solution was approximated by eliminating projection collision at each CP. MLC motion continuity and maximum speed were included in the cost function to ensure deliverability. The optimization started with randomized initial CP apertures, followed by solving state-transition equations for following CPs. Two grid arrays (9 and 10 targets respectively) were tested for plan quality. For each grid of target, the arc collimator angle was planned with 0 and 30 degrees for comparison. Prescription was 20 Gy per fraction. Monte Carlo simulation dose engine from matRad toolkit was used for dose calculation. Key dosimetric endpoints including target mean dose, D5%(Gy) and D95%(Gy), were reported. RESULTS Average calculation time on the AMD Ryzen 5 5600 × 6-Core 3.7GHz CPU and 32GB RAM platform varied from 31 to 44 minutes. One zero-degree collimator and one thirty-degree collimator were generated for each target array. For nine-target array, mean target dose from both plans ranged from 23.41 to 26.55 Gy, while D5%(Gy) and D95%(Gy) ranged from 25.45 to 30.16 Gy, and 20.00 to 22.21 Gy, respectively. For ten-target array, the range of target mean, D5%(Gy) and D95%(Gy) were 23.82 to 28.74 Gy, 26.50 to 33.11 Gy, and 20.00 to 22.49 Gy. CONCLUSION A fast, automatic planning solution for multi-focal DCA GRID therapy was developed. It provides clinically feasible plans with high efficiency for small target arrays for the late-stage cancer patient. The implementation provides excellent coverage for deep-seated tumors where alloy grid solution could fail to meet coverage objectives. Additional patients are needed in the future to further refine the technique.

Abstract
OBJECTIVE This study aimed to analyze the effectiveness of acupuncture combined with Chinese herbal medicine (CHM) on mood disorder symptoms for menopausal women. METHODS A total of 95 qualified Chinese participants were randomly assigned to one of three groups: 31 in the acupuncture combined with CHM group (combined group), 32 in the acupuncture combined with CHM placebo group (acupuncture group) and 32 in the CHM combined with sham acupuncture group (CHM group). The patients were treated for 8 weeks and followed up for 4 weeks. The data were collected using the Greene Climacteric Scale (GCS), self-rating depression scale (SDS), self-rating anxiety scale (SAS) and safety index. RESULTS The three groups each showed significant decreases in the GCS, SDS and SAS after treatment (p < 0.05). Furthermore, the effect on the GCS total score and the anxiety domain lasted until the follow-up period in the combined group (p < 0.05). Within the three groups, there was no difference in GCS and SAS between the three groups after treatment (p > 0.05). However, the combined group showed significant improvement in the SDS, compared with both the acupuncture group and the CHM group at 8 weeks and 12 weeks (p < 0.05). No obvious abnormal cases were found in any of the safety indexes. CONCLUSIONS The results suggest that either acupuncture, or CHM or combined therapy offer safe improvement of mood disorder symptoms for menopausal women. However, the combination therapy was associated with more stable effects in the follow-up period and a superior effect on improving depression symptoms.

Abstract
Photodynamic therapy (PDT) initially employed red light, which caused some patients to experience permanent bladder contractions. PDT using the FDA-approved drug hexaminolevulinate (HAL), which produces protoporphyrin IX (PpIX) in the tumor, showed some promise but has low efficacy in treating non-muscle-invasive bladder cancer (NMIBC). We developed singlet oxygen-activatable prodrugs of two anticancer drugs, paclitaxel and mitomycin C, to enhance the antitumor effect of PpIX-PDT without producing systemic side effects, by promoting only local release of the active chemotherapeutic agent. Orthotopic NMIBC model was used to compare the efficacy of prodrugs only, PpIX-PDT, and prodrugs + PpIX-PDT. 532 nm laser with a total power of 50 mW for 20 min (60 J, single treatment) was used with HAL and prodrugs. Histology and microscopic methods with image analysis were used to evaluate the tumor staging, antitumor efficacy, and local toxicity. Prodrug + PpIX-PDT produced superior antitumor efficacy than PpIX-PDT alone with statistical significance. Both PpIX-PDT alone and combination therapy resulted in mild damage to the bladder epithelium in the normal bladder area with no apparent damage to the muscle layer. Overall, SO-cleavable prodrugs improved the antitumor efficacy of PpIX-PDT without causing severe and permanent damage to the bladder muscle layer.

Abstract
Gamma-glutamyl transferase 1 (GGT1) is a critical enzyme involved in the hydrolysis and/or transfer of gamma-glutamyl groups of glutathione, which helps maintain cysteine levels in plasma. In this study, we synthesized L-ABBA analogs to investigate their inhibitory effect on GGT1 hydrolysis and transpeptidase activity, with the goal of defining the pharmacophore of L-ABBA. Our structure-activity relationship (SAR) study revealed that an α-COO- and α-NH3+ group, as well as a two-CH2 unit distance between α-C and boronic acid, are essential for the activity. The addition of an R (alkyl) group at the α-C reduced the activity of GGT1 inhibition, with L-ABBA being the most potent inhibitor among the analogs. Next, we investigated the impact of L-ABBA on plasma levels of cysteine and GSH species, with the expectation of observing reduced cysteine levels and enhanced GSH levels due to its GGT1 inhibition. We administered L-ABBA intraperitoneally and determined the plasma levels of cysteine, cystine, GSH, and GSSG using LCMS. Our results showed time- and L-ABBA dose-dependent changes in total plasma cysteine and GSH levels. This study is the first to demonstrate the regulation of plasma thiol species upon GGT1 inhibition, with plasma cystine levels reduced by up to ∼75% with L-ABBA (0.3 mg/dose). Cancer cells are highly dependent on the uptake of cysteine from plasma for maintaining high levels of intracellular glutathione. Thus, our findings suggest that GGT1 inhibitors, such as L-ABBA, have a potential to be used for GSH reduction thereby inducing oxidative stress in cancer cells and reducing their resistance to many chemotherapeutic agents.

Abstract
Bladder cancer is the first cancer for which PDT was clinically approved in 1993. Unfortunately, it was unsuccessful due to side effects like bladder contraction. Here, we summarized the recent progress of PDT for bladder cancers, focusing on photosensitizers and formulations. General strategies to minimize side effects are intravesical administration of photosensitizers, use of targeting strategies for photosensitizers and better control of light. Non-muscle invasive bladder cancers are more suitable for PDT than muscle invasive and metastatic bladder cancers. In 2010, the FDA approved blue light cystoscopy, using PpIX fluorescence, for photodynamic diagnosis of non-muscle invasive bladder cancer. PpIX produced from HAL was also used in PDT but was not successful due to low therapeutic efficacy. To enhance the efficacy of PpIX-PDT, we have been working on combining it with singlet oxygen-activatable prodrugs. The use of these prodrugs increases the therapeutic efficacy of the PpIX-PDT. It also improves tumor selectivity of the prodrugs due to the preferential formation of PpIX in cancer cells resulting in decreased off-target toxicity. Future challenges include improving prodrugs and light delivery across the bladder barrier to deeper tumor tissue and generating an effective therapeutic response in an In vivo setting without causing collateral damage to bladder function.

Abstract
Fine-tuned ion transport across nanoscale pores is key to many biological processes, including neurotransmission. Recent advances have enabled the confinement of water and ions to two dimensions, unveiling transport properties inaccessible at larger scales and triggering hopes of reproducing the ionic machinery of biological systems. Here we report experiments demonstrating the emergence of memory in the transport of aqueous electrolytes across (sub)nanoscale channels. We unveil two types of nanofluidic memristors depending on channel material and confinement, with memory ranging from minutes to hours. We explain how large time scales could emerge from interfacial processes such as ionic self-assembly or surface adsorption. Such behavior allowed us to implement Hebbian learning with nanofluidic systems. This result lays the foundation for biomimetic computations on aqueous electrolytic chips.

Abstract
Neuroimaging studies of autism spectrum disorder (ASD) have been predominantly unimodal. While many fMRI studies have reported atypical activity patterns for diverse tasks, the MEG literature in ASD remains comparatively small. Our group recently reported atypically increased event-related theta power in individuals with ASD during lexicosemantic processing. The current multimodal study examined the relationship between fMRI BOLD signal and anatomically-constrained MEG (aMEG) theta power. Thirty-three adolescents with ASD and 23 typically developing (TD) peers took part in both fMRI and MEG scans, during which they distinguished between standard words (SW), animal words (AW), and pseudowords (PW). Regions-of-interest (ROIs) were derived based on task effects detected in BOLD signal and aMEG theta power. BOLD signal and theta power were extracted for each ROI and word condition. Compared to TD participants, increased theta power in the ASD group was found across several time windows and regions including left fusiform and inferior frontal, as well as right angular and anterior cingulate gyri, whereas BOLD signal was significantly increased in the ASD group only in right anterior cingulate gyrus. No significant correlations were observed between BOLD signal and theta power. Findings suggest that the common interpretation of increases in BOLD signal and theta power as 'activation' require careful differentiation, as these reflect largely distinct aspects of regional brain activity. Some group differences in dynamic neural processing detected with aMEG that are likely relevant for lexical processing may be obscured by the hemodynamic signal source and low temporal resolution of fMRI.

Abstract
Inhibitors of gamma-glutamyl transpeptidase (GGT1, aka gamma-glutamyl transferase) are needed for the treatment of cancer, cardiovascular illness and other diseases. Compounds that inhibit GGT1 have been evaluated in the clinic, but no inhibitor has successfully demonstrated specific and systemic GGT1 inhibition. All have severe side effects. L-2-amino-4‑boronobutanoic acid (l-ABBA), a glutamate analog, is the most potent GGT1 inhibitor in vitro. In this study, we have solved the crystal structure of human GGT1 (hGGT1) with ABBA bound in the active site. The structure was interrogated to identify interactions between the enzyme and the inhibitor. Based on these data, a series of novel ABBA analogs were designed and synthesized. Their inhibitory activity against the hydrolysis and transpeptidation activities of hGGT1 were determined. The lead compounds were crystalized with hGGT1 and the structures solved. The kinetic data and structures of the complexes provide new insights into the critical role of protein structure dynamics in developing compounds for inhibition of hGGT1.

Abstract
BACKGROUND Psoriasis is a chronic immune-mediated inflammatory skin disease that often leads to a diminished quality of life. Goals of treating patients with psoriasis have shifted with more focus on achieving near or complete clearance of the skin. Guselkumab, a fully human monoclonal antibody targeting interleukin-23, is effective in treating moderate-to-severe psoriasis. OBJECTIVE To describe the baseline characteristics of patients with moderate-to-severe psoriasis achieving super-response (Psoriasis Area and Severity Index [PASI] 100 response at Weeks 20 and 28) after commencing guselkumab treatment. METHODS Pooled data from VOYAGE-1 and VOYAGE-2 studies identified super-response; baseline demographic, disease, and pharmacokinetic characteristics were compared with non-super-response. A stepwise logistic regression analysis identified which factors were potentially predictive of super-response status, with significance level of 0.1. RESULTS A subset of patients randomized to guselkumab comprised this post hoc analysis (n=664); 271 patients achieved super-response vs 393 with non-super-response. Patient age at study entry and baseline body weight (≤90 kg vs >90 kg), PASI, and Investigator's Global Assessment (IGA) score were significant predictors of super-response status, with odds ratios (95% confidence intervals) of 0.98 (0.967-0.993; p=0.003), 1.42 (1.026-1.977; p=0.034), 0.97 (0.955-0.993; p=0.007), and 0.66 (0.433-0.997; p=0.048), respectively. More patients with super-response achieved an early response: Week 2 PASI 75 (5.5% vs 1.8%) and Week 8 PASI 100 (22.5% vs 3.3%) vs non-super-response. Median serum guselkumab concentrations through Week 28 were slightly greater in patients with super-response vs non-super-response. CONCLUSION Guselkumab was more likely to achieve early clinical responses (complete skin clearance) in younger patients, less obese patients, and patients with less severe psoriasis.

Abstract
BackgroundGuselkumab (GUS) demonstrated efficacy and a favorable safety profile in active PsA in the Phase (Ph) 21 and Ph3 DISCOVER-1&2 trials2,3 and in moderate-to-severe plaque psoriasis (PsO) in the Ph3 VOYAGE-1&2 trials.4,5ObjectivesTo assess long-term safety of GUS across PsA/PsO trials.MethodsUsing pooled safety data through 2 years (yrs) from PsA trials (N=1229; GUS 100 mg every 4/8 weeks [Q4W/Q8W])1-3 and through 5 yrs from PsO trials (N=1721; GUS 100 mg Q8W),4,5 incidences of serious adverse events (SAEs); gastrointestinal (GI)-related SAEs and other targeted AEs; including candidiasis, uveitis, and opportunistic infections (OIs) were evaluated. Incidence rates (IRs) were calculated as the number of events per 100 pt-yrs (PY) of follow-up with 95% CI. Patients (pts) with an IBD history were not excluded in PsA/PsO trials. Max exposure duration was W100 for PsA trials and W252 for PsO trials.ResultsThe PsA and PsO populations had comparable mean age and BMI. IRs of SAEs and GI-related SAEs were generally similar between GUS- and PBO-treated pts during PBO-controlled periods, and between PsA pts receiving GUS Q4W/Q8W for up to 2 yrs and PsO pts receiving GUS Q8W for up to 5 yrs (Table 1). IRs of other targeted AEs of interest were low. OIs did not occur in PsO pts and were infrequent in PsA pts (Table 1). Candidal infections were infrequent and non-serious. Iridocyclitis was reported in 1 PBO- and 1 GUS Q8W-treated PsA pt. No exacerbations or new onset of IBD or active tuberculosis was reported in GUS-treated PsA/PsO pts.Table 1.Targeted AEs of InterestPooled PsA*Pooled PsOThrough 2 YrsThrough 5 YrsGUS 100 mg Q4W (N=373)GUS 100 mg Q8W (N=475)PBO→GUS 100 mg Q4W (N=352)aPBO→GUS 100 mg Q8W (N=29)aGUS Combined (N=1229)GUS 100 mg Q8W (N=1221)bADA→GUS 100 mg Q8W (N=500)cGUS Combined (N=1721)Total PY645748461171871525419127166Mean PY1.71.61.30.61.54.33.84.2Events/100 PY (95% CI)Overall SAEs4.65(3.14, 6.64)6.42(4.73, 8.51)5.86(3.86, 8.52)0.00(0.00, 17.24)5.61(4.59, 6.79)5.18(4.58, 5.83)4.55(3.64, 5.61)5.01(4.50, 5.56)GI-related SAEs0.46(0.10, 1.36)0.27(0.03, 0.97)0.00 (0.00, 0.65)0.00(0.00, 17.24)0.27(0.09, 0.62)0.44(0.28, 0.66)0.42(0.18, 0.82)0.43(0.29, 0.61)OIsd0.00(0.00, 0.46)0.27(0.03, 0.97)0.22(0.01, 1.21)0.00(0.00, 17.24)0.16(0.03, 0.47)0.00(0.00, 0.06)0.00(0.00, 0.16)0.00(0.00, 0.04)Candida infections0.31(0.04, 1.12)0.00(0.00, 0.40)0.00(0.00, 0.65)0.00(0.00, 17.24)0.11(0.01, 0.39)0.49(0.32, 0.73)0.52(0.25, 0.96)0.50(0.35, 0.70)Non-pathogen specific fungal infections, suspicious for candida0.00(0.00, 0.46)0.27(0.03, 0.97)0.00(0.00, 0.65)0.00(0.00, 17.24)0.11(0.01, 0.39)0.11(0.04, 0.25)0.16(0.03, 0.46)0.13(0.06, 0.24)Uveitis/ Iridocyclitis0.00(0.00, 0.46)0.13(0.00, 0.75)0.00(0.00, 0.65)0.00(0.00, 17.24)0.05(0.00, 0.30)0.00(0.00, 0.06)0.00(0.00, 0.16)0.00(0.00, 0.04)*In PsA Ph2, data after early escape at W16 were excluded.

Abstract
A 25-year-old women was admitted to the department of Neurology in Affiliated 2nd Hospital of Hainan Medical University due to recurrent syncope for 8 years and return for 2 months. She had multiple episodes of syncope at onset. She presented with the feeling of weakness in both lower limbs, and fatigue in the past year. She experienced pain in the waist and limbs joint in recent three months. Physical examination showed joint hyperactivity in metacarpophalangeal joints of both upper limbs, increased skin elasticity. Active-standing transcranial Doppler (TCD) test showed that the average heart rate (HR) and the average middle cerebral artery (MCA) blood flow velocity in the supine position were 79 beats/min and 62 cm/s, respectively; while the average HR and the average MCA blood flow velocity in the standing position were 126 beats/min, 47 cm/s. Meanwhile,the blood pressure was normal during the test of supine-to-standing TCD. Genetic testing indicated LDB3 transgenation. The patient was diagnosed as postural tachycardia syndrome (joint-hypermobility-related), Ehlers-Danlos syndrome, and relieved by fluid infusion and rehabilitation therapy.

Abstract
BackgroundThe VOYAGE-1 and VOYAGE-2 phase 3 studies evaluated efficacy and safety of guselkumab (GUS) in patients with moderate-to-severe plaque psoriasis.ObjectivesTo assess the five-year efficacy of GUS by baseline disease characteristics and treatment history.MethodsThis study evaluated 1829 patients randomized to GUS, placebo (PBO)→GUS, and adalimumab (ADA) →GUS from the VOYAGE-1 and VOYAGE-2 trials. All patients received open-label GUS 100 mg every 8 weeks (Q8W) during Week (W) 52 to W252 in VOYAGE-1 and during W76 to W252 in VOYAGE-2. The proportions of combined GUS patients (including PBO→GUS and ADA→GUS) achieving Investigator’s Global Assessment of cleared or minimal (IGA-0/1) and Psoriasis Area and Severity Index (PASI) 90 response were evaluated from W100 to W252 by baseline PASI (<20/≥20) and IGA (<4/=4) scores, body surface area (BSA; <20%/≥20%), and prior psoriasis treatments. Analysis was performed using observed data after applying treatment failure rules.ResultsAt W252, proportions of combined GUS patients achieving IGA 0/1 or PASI 90, respectively, were comparable or numerically greater for patients with baseline PASI < 20 (85.4%; 81.1%) vs PASI ≥ 20 (81.4%; 83.8%); IGA < 4 (85.1%; 82.7%) vs IGA = 4 (78.9%; 81.1%); BSA < 20% (85.1%; 82.7%) vs BSA ≥ 20% (82.6%; 82.0%); no prior phototherapy (83.3%; 84.0%) vs prior phototherapy (83.8%; 81.1%); no prior non-biologic systemic therapy (84.5%; 83.0%) vs prior non-biologic systemic therapy (83.2%; 82.0%); and no prior biologics (85.3%; 83.8%) vs prior biologics (76.7%; 76.3%). This trend was consistent at each timepoint evaluated from W100 to W252.ConclusionThis analysis demonstrated that the high degree of efficacy of GUS treatment is durable through 5 years among broad subpopulations of patients with varying disease severity characteristics and previous psoriasis treatments.ReferencesNoneDisclosure of InterestsKenneth Gordon Grant/research support from: AbbVie, Almirall, Amgen, BMS, Celgene, Dermira, Dermavant, Eli Lilly, Janssen, LEO Pharma, Novartis, Ortho Dermatologics, Pfizer, Sun Pharma, and UCB Pharma, Joseph F.

Abstract
The proband was an 8-year-old boy, complaining of progressively decreased vision in both eyes for 3 years. The electroretinogram was characterized by supernormal rod response. While the responses of the rod and cone system were reduced, the amplitudes of dark-adapted electroretinogram responses at a high intensity were supernormal. A homozygous non-frameshift deletion variant c.1002-1004del (p. L335del) in KCNV2 was found by the Next Generation Sequencing using a custom designed panel. His father was a heterozygous carrier of this variant. In silico analysis indicated the variant was harmful. The proband was diagnosed as cone dystrophy type 3B which also known as cone dystrophy with supernormal rod response.

Abstract
We established a light-activatable prodrug strategy that produces the combination effect of photodynamic therapy (PDT) and site-specific chemotherapy. Prodrugs are activated by singlet oxygen (SO), generated from PS and visible or near IR light, in either intra- or inter-molecular manner. The goal of this study is to evaluate cytotoxic effects of non-mitochondria targeted prodrugs of a number of anticancer drugs with different mechanisms of action. They were tested in both 2D and 3D in vitro conditions via inter-molecular activation of prodrugs by SO generated in mitochondria by protoporphyrin IX-PDT (PpIX-PDT). Prodrugs of anticancer drugs (paclitaxel, SN-38, combrestatin A4, and mitomycin C) were synthesized using facile and high yielding reactions. Non-mitochondria targeted prodrugs showed limited dark toxicity while all of them showed greatly enhanced phototoxicity compared to PpIX-PDT in the 2D culture model. Prodrugs generated up to about 95% cell killing at 2.5 μM when administered with hexyl-aminolevulinate (HAL) to produce Protoporphyrin IX in cancer cells in both 2D monolayer and 3D spheroids model. The data demonstrate that mitochondria-targeting of prodrugs is not fully essential for our inter-molecular activation prodrug strategy. The prodrug strategy also worked for anticancer drugs with diverse MOAs.

Abstract
OBJECTIVE To compare the efficacy of a novel rotary file system (EZ Pass) with two well-established rotary file systems(ProTaper Gold and ProTaper Next)for removal of Enterococcus faecalis from infected root canals in extracted maxillary central incisors. METHODS Models of root canal infection with Enterococcus faecalis were constructed in 51 extracted singlerooted maxillary central incisors.One of the incisor model with infected root canal was demineralized, sectioned, and stained with Brown & Brenn technique for microscopic observation; The remaining 50 models were randomly divided into 5 groups(n=10) for treatment with EZ Pass, ProTaper Gold, ProTaper Next, 0.9% NaCl or 2% NaOCl.Samples were collected from the infected root canals before and after the treatments to assess the percent reduction and logarithmic reduction value of CFU in the root canals. RESULTS The incisors with root canal infection by Enterococcus faecalis showed obvious biofilms on the surface of the root canals and massive bacterial invasion deep into the dentinal tubules, with a maximum invasion depth of about 475 μm.The percent reduction of the CFU did not differ significantly after treatments with EZ Pass, ProTaper Gold, ProTaper Next and 2% NaOCl (P > 0.05), but all these treatments resulted in significantly greater reduction than 0.9% NaCl (P < 0.01).The logarithmic reduction of CFU were comparable after treatments with EZ Pass (1.47±0.12), ProTaper Gold (1.74±0.14) and ProTaper Next (1.63±0.17;P > 0.05). CONCLUSION EZ Pass can significantly reduce the bacterial load in infected root canals with an equivalent bacterial elimination capacity to ProTaper Gold and ProTaper Next.

Abstract
BACKGROUND Psoriasis is a chronic disease requiring long-term therapy. OBJECTIVES Physician- and patient-reported outcomes were evaluated through week 252 in VOYAGE 1 and VOYAGE 2. METHODS In total, 1829 patients were randomized at baseline to receive guselkumab 100 mg every 8 weeks, placebo or adalimumab. Patients receiving placebo crossed over to guselkumab at week 16. Patients receiving adalimumab crossed over to guselkumab at week 52 in VOYAGE 1, and randomized withdrawal and retreatment occurred at weeks 28-76 in VOYAGE 2; all patients then received open-label guselkumab through week 252. Efficacy and health-related quality of life (HRQoL) endpoints were analysed through week 252. Safety was monitored through week 264. RESULTS The proportions of patients in the guselkumab group who achieved clinical responses at week 252 in VOYAGE 1 and VOYAGE 2, respectively, were 84·1% and 82·0% [≥ 90% improvement in Psoriasis Area and Severity Index (PASI)]; 82·4% and 85·0% [Investigator's Global Assessment (IGA) 0 or 1]; 52·7% and 53·0% (100% improvement in PASI) and 54·7% and 55·5% (IGA 0). HRQoL endpoints were achieved as follows: 72·7% and 71·1% of patients (Dermatology Life Quality Index 0 or 1: no effect on patient's life); 42·4% and 42·0% [Psoriasis Symptoms and Signs Diary (PSSD) symptom score = 0] and 33·0% and 31·0% (PSSD sign score = 0). As measured in VOYAGE 2 only, approximately 45% of patients achieved ≥ 5-point reduction in Short Form-36 physical and mental component scores, and 80% reported no anxiety or depression (Hospital Anxiety and Depression Scale scores < 8). Similar findings were reported for adalimumab crossovers. These effects were maintained from week 52 in VOYAGE 1 and week 100 in VOYAGE 2. No new safety signals were identified. CONCLUSIONS Guselkumab maintains high levels of clinical response and improvement in patient-reported outcomes through 5 years in patients with moderate-to-severe psoriasis.

Abstract
Background:DISCOVER 1&2 (PsA) and VOYAGE 1&2 (PsO) are Phase 3 trials of guselkumab (GUS).Objectives:Compare safety results through up to 1yr of GUS in PsA and PsO pts.Methods:In DISCOVER, 1120 pts with active PsA despite standard therapy were treated. Most pts were biologic-naïve; ~30% in DISCOVER 1 had previous exposure to 1-2 TNFi. Concomitant MTX (57%), oral corticosteroids (17%), and NSAIDs (64%) were permitted. Pts were randomized to SC GUS 100mg at W0, W4, then Q8W; GUS 100mg Q4W; or PBO. At W24, PBO patients were switched to GUS 100mg Q4W. In VOYAGE, in which concomitant MTX use was prohibited, 1245 pts with moderate to severe PsO were treated and randomized to SC GUS 100 mg at W0, W4, W12, then Q8W; or PBO at W0, W4, W12, with crossover to GUS at W16, W20, then Q8W. AEs and laboratory parameters, analyzed by National Cancer Institute-Common Terminology Criteria for AEs [NCI-CTCAE] toxicity grades, were summarized through the PBO-controlled periods and 1yr.Results:Safety profiles were generally consistent across the GUS PsO and PsA clinical programs (Table 1). Time-adjusted incidence rates for numbers of AEs, serious AEs, serious infections, malignancy, MACE and AEs leading to d/c were generally similar between PsO and PsA. No cases of anaphylaxis or opportunistic infections were reported. Proportions of pts with decreased neutrophil counts and elevations in hepatic transaminases were slightly higher in PsA vs PsO. These abnormalities were mostly of NCI-CTCAE Grade 1 or 2 (<LLN-1000/mm3 for neutrophils; <5.0 x ULN for AST/ ALT), generally transient, required no medical interventions, resolved spontaneously, and did not lead to interruption or d/c of treatment. Through 1yr, proportions of pts with ALT/AST elevations in PsA trials were slightly higher for GUS Q4W than Q8W and in pts with vs without baseline MTX use.Conclusion:The GUS safety profile was generally consistent in PsA and PsO GUS-treated pts through 1yr of the DISCOVER and VOYAGE trials.Table 1.Treatment-Emergent AEs During PBO-controlled Period and Through 1Yr: VOYAGE & DISCOVER TrialsPooled VOYAGE 1&2Pooled DISCOVER 1&2Time PeriodW0-16Through 1YrW0-24bThrough 1Yr(N=)PBO(422)GUS Q8W(823)Combined GUSa(1221)PBOc(372)GUS Q8W(375)GUS Q4W (373)GUS Q8W(375)GUS Q4W (373)Combined GUS† (1100)Total pt-yrs of follow-up128255974173173172384385973Incidence/100 pt-yrs (95% CI)dAEs317 (287,349)330 (308,353)259 (249, 270)219 (198,243)256 (232,281)221 (200, 245)218 (203,233)177 (164,191)191 (182, 199)SAEs5 (2, 10)6 (4, 10)6 (5, 8)9 (5, 15)4 (2, 8)5 (2, 10)6 (4, 9)4 (2, 7)6 (4, 7)AEs leading to study agent d/c3 (0.9, 8)4 (2, 8)2 (2, 4)4 (2, 8)3 (1, 7)7 (4, 12)2 (1, 4)4 (2, 6)3 (2, 5)Infections86 (71, 104)98 (86, 111)98 (92, 104)58 (48, 71)58 (47, 71)63 (51, 76)58 (50, 66)53 (46, 61)55 (50, 60)Serious Infections0. 8 (0, 4)0.4 (0, 2)1 (0.5, 2)4 (2, 8)0.6 (0, 3)2 (0.4, 5)2 (0.6, 3)1 (0, 2)2 (0.9, 3)All Malignancy0 (0, 2)0.4 (0, 2)1 (0.4, 2)0.6 (0, 3)1 (0, 4)0 (0, 2)0.5 (0, 2)0 (0, 0. 8)0 (0, 1)MACE0 (0, 2)0.4 (0, 2)0.4 (0, 1)0.6 (0, 3)0 (0, 2)0.6 (0, 3)0 (0, 0.8)0.3 (0, 1.4)0.1 (0, 0.6)% pts with ≥1 injection site rxn3.14.55.00.31.31.11.62.41.7aPlacebo crossover pts were included in the combined GUS column after crossover to GUSbFor all pts who d/c study treatment early with the last dose of PBO/GUS prior to W24 and who did not receive any PBO/GUS at or after Wk24, all data including the final safety follow-up visit collected through 1yr were includedcFor pts in PBO group who switched to GUS due to cross-over or inadvertently, only data prior to first administration of GUS were included.dCI based on an exact method assuming observed number of events follows a Poisson distributionDisclosure of Interests:Alice B Gottlieb Consultant of: Anaptyps Bio, Avotres Therapeutics, Beiersdorf, Boehringer Ingelheim, Bristol-Myers-Squibb, Eli Lilly, Janssen, LEO Pharma, Novartis, Sun Pharmaceuticals, UCB, and Xbiotech, Grant/research support from: Boehringer Ingelheim, Janssen, Novartis, Sun Pharmaceuticals, UCB, and Xbiotech, Joseph F.

Abstract
Background:Guselkumab (GUS), a human monoclonal antibody that specifically binds to the p19-subunit of interleukin (IL)-23, demonstrated efficacy in the Phase 3 VOYAGE 1&2 trials of patients (pts) with moderate to severe plaque psoriasis (PsO)1,2 and in the DISCOVER 1&2 trials of pts with active psoriatic arthritis (PsA).3,4 IL-17 inhibitors used to treat PsO and PsA have been associated with exacerbation or new onset of inflammatory bowel disease (IBD) (e.g., Crohn’s disease or ulcerative colitis).5Objectives:Evaluate the incidence of gastrointestinal (GI)-related and overall serious adverse events (SAEs) from pooled safety data through 1-year of GUS 100 mg treatment from the VOYAGE 1&2 and DISCOVER 1&2 trials.Methods:Using pooled safety data from the VOYAGE 1&2 PsO trials and DISCOVER 1&2 PsA trials, SAEs related to GI disorders were identified using the Medical Dictionary for Regulatory Activities (MedDRA) system-organ class “GI disorders”. Pts with a previous history of IBD were not excluded in these trials; medical history of IBD was collected at baseline in DISCOVER 1&2. Rates of overall SAEs and GI-related SAEs were calculated as the number of SAEs per 100 pt-years (PY) of follow-up (95% confidence intervals). Data are presented for the placebo (PBO)-controlled period (Weeks 0-16 for VOYAGE 1&2; Weeks 0-24 for DISCOVER 1&2) and through 1-year (defined as through Week 48 for VOYAGE 1&2; through Week 60 for DISCOVER 1, and through Week 52 for DISCOVER 2). Events of uveitis and opportunistic infections were also analyzed.Results:Through the PBO-controlled period, the overall rates of GI-related SAEs per 100 PY for pooled VOYAGE 1&2 were: PBO 0.78 (0.02, 4.34), GUS q8w 0; and for pooled DISCOVER 1&2: PBO 0.58 (0.01, 3.23), GUS q8w 0.58 (0.01, 3.21), GUS q4w 0. The GI-related SAEs included: gastrointestinal hemorrhage (PBO; n=1) for pooled VOYAGE 1&2; and inflammatory bowel disease (PBO; n=1) and mechanical ileus (GUS q8w; n=1) for pooled DISCOVER 1&2. Through 1-year, the overall rates of GI-related SAEs for pooled VOYAGE 1&2 were: Combined GUS group (GUS q8w and PBO→GUS groups) 0.51 (0.17, 1.20); and for pooled DISCOVER 1&2: GUS q8w 0.52 (0.06, 1.88), GUS q4w 0, Combined GUS group (GUS q8w, GUS q4w, and PBO→GUS groups) 0.21 (0.02, 0.74). The GI-related SAEs in the Combined GUS group for pooled VOYAGE 1&2 included: gastritis, hemorrhoids, inguinal hernia, pancreatitis, and umbilical hernia (0.10/100PY [0.00, 0.57]; n=1 for each); and in the Combined GUS group for pooled DISCOVER 1&2: mechanical ileus and pancreatitis chronic (0.10/100PY [0.00, 0.57]; n=1 for each). Overall, no cases of exacerbation or new onset of IBD were reported in GUS-treated pts, including 2 pts with a prior history of IBD in DISCOVER 1&2 (total PY of follow-up for the Combined GUS groups in VOYAGE and DISCOVER were 974 and 973, respectively). Through the PBO-controlled period, rates of overall SAEs for GUS-treated pts were comparable to PBO-pts and SAE rates remained low through 1-year of follow-up in the VOYAGE 1&2 and DISCOVER 1&2 trials. There were no reported cases of uveitis, opportunistic infections, or tuberculosis in GUS-treated pts through 1-year.Conclusion:Through 1-year of follow-up with GUS treatment in pooled VOYAGE 1&2 and DISCOVER 1&2, GI-related SAE rates were low. There were no reported cases of uveitis, opportunistic infections, or new onset/exacerbation of IBD in GUS-treated pts. No new safety concerns were identified through 1-year.References:[1]Blauvelt A., et al. J Am Acad Dermatol. 2017;76:405-17.[2]Reich K., et al. J Am Acad Dermatol. 2017;76:418-31.[3]Deodhar A., et al.

Abstract
Background:VOYAGE 1, a phase-3, double-blinded, placebo- and active comparator-controlled study evaluated the efficacy and safety of guselkumab (GUS; a fully human anti-interleukin-23 monoclonal antibody) in patients with moderate-to-severe plaque psoriasis.1,2,3Objectives:To assess the efficacy and safety through 5 years of continuous GUS treatment.Methods:In VOYAGE 1, patients were randomized to GUS 100 mg at Weeks 0, 4, 12, then every 8 weeks (q8w); placebo at Weeks 0, 4, 12 followed by GUS 100 mg at Weeks 16, 20 then q8w; or adalimumab 80 mg at Week 0, 40 mg at Week 1, then 40 mg every 2 weeks (q2w) through Week 47. At Week 52, all patients continued open-label GUS through Week 252. Efficacy assessments included proportions of patients achieving ≥90% or 100% improvement in Psoriasis Area and Severity Index (PASI 90, PASI 100), and Investigator’s Global Assessment scores of cleared/minimal or cleared (IGA 0/1, IGA 0). Three statistical methods were used to analyze efficacy: prespecified Treatment Failure Rules (TFR), Nonresponder Imputation (NRI), and As Observed (OBS). For TFR analyses, patients who discontinued study agent due to lack of efficacy, worsening of psoriasis, or use of a protocol-prohibited psoriasis treatment were considered nonresponders. For NRI analyses, patients with missing efficacy data (regardless of the reason) after application of TFR were counted as nonresponders. For OBS analyses, missing data were not imputed. Safety was assessed through Week 264.Results:Among a total of 494 patients randomized to GUS at Week 0 (N=329) and placebo patients who crossed over to GUS at Week 16 (N=165), 76.9% (380/494) continued study agent through Week 252. PASI 90 responses were well-maintained with up to 5 years of continuous GUS use. At Week 52, PASI 90 response rates were 79.7%, 75.5%, and 80.6% based on TFR, NRI, and OBS analyses, respectively; corresponding rates at Week 252 were 84.1%, 66.6%, and 86.6%. Likewise, PASI 100, IGA 0/1, and IGA 0 responses were maintained from Week 52 through Week 252 (Table 1). Efficacy was also maintained through Week 252 in patients randomized to GUS at Week 0 (N=329). Through the end of the study for all patients (GUS group and adalimumab→GUS crossover group; N=774), the proportion of patients reporting at least one adverse event (AE), serious AE, or discontinuation due to AEs were 87.7%, 16.4%, and 6.1%, respectively. Rates of AEs of interest through Week 264 were as follows: serious infections (2.8%), malignancies (nonmelanoma skin cancer [1.7%]; cancer other than nonmelanoma skin cancer [2.3%]), major adverse cardiovascular events (1.0%), and suicidal ideation and behavior (0.6%).Conclusion:High efficacy response rates were maintained (regardless of the method used to analyze data) and no new safety concerns were identified through 5 years of continuous GUS treatment in VOYAGE 1.References:[1]Blauvelt A et al.

Abstract
A 57-year-old man was admitted to hospital with diarrhea for 10 months and dizziness for 4 months. The patient had 1-2 liters watery stool per day, without pyogenic blood or abnormality in gastroenteroscopy examination. The level of hemoglobin and albumin was generally normal, and fasting test was positive. At the same time, he was accompanied with hyperalgesia of lower limbs and orthostatic hypotension. After the discussion of multiple disciplinary teams, the patient was diagnosed with amyloidosis by sural nerve biopsy, myocardial MRI, and the assays of urine immunoelectrophoresis and serum free light chain. Light chain amyloidosis was confirmed after excluded the diagnosis of familial amyloidosis. The patient was improved after courses of chemotherapy with melphalan and dexamethasone.

Abstract
Overexpression of γ-glutamyl transpeptidase (GGT1) has been implicated in an array of human diseases including asthma, reperfusion injury, and cancer. Inhibitors are needed for therapy, but development of potent, specific inhibitors of GGT1 has been hampered by a lack of structural information regarding substrate binding and cleavage. To enhance our understanding of the molecular mechanism of substrate cleavage, we have solved the crystal structures of human GGT1 (hGGT1) with glutathione (a substrate) and a phosphate-glutathione analog (an irreversible inhibitor) bound in the active site. These are the first structures of any eukaryotic GGT with the cysteinylglycine region of the substrate-binding site occupied. These structures and the structure of apo-hGGT reveal movement of amino acid residues within the active site as the substrate binds. Asn-401 and Thr-381 each form hydrogen bonds with two atoms of GSH spanning the γ-glutamyl bond. Three different atoms of hGGT1 interact with the carboxyl oxygen of the cysteine of GSH. Interactions between the enzyme and substrate change as the substrate moves deeper into the active site cleft. The substrate reorients and a new hydrogen bond is formed between the substrate and the oxyanion hole. Thr-381 is locked into a single conformation as an acyl bond forms between the substrate and the enzyme. These data provide insight on a molecular level into the substrate specificity of hGGT1 and provide an explanation for seemingly disparate observations regarding the enzymatic activity of hGGT1 mutants. This knowledge will aid in the design of clinically useful hGGT1 inhibitors.

Abstract
Every choice we make in health professions education has a cost, whether it be financial or otherwise; by choosing one action (e.g., integrating more simulation, studying more for a summative examination) we lose the opportunity to take an alternative action (e.g., freeing up time for other teaching, leisure time). Economics significantly shapes the way we behave and think as educators and learners and so there is increasing interest in using economic ways of thinking and approaches to examine and understand how choices are made, the influence of constraints and boundaries in educational decision making, and how costs are felt. Thus, in this article, we provide a brief historical overview of modern economics, to illustrate how the core concepts of economics-scarcity (and desirability), rationality, and optimization-developed over time. We explain the important concept of bounded rationality, which explains how individual, meso-factors and contextual factors influence decision making. We then consider the opportunities that these concepts afford for health professions education and research. We conclude by proposing that embracing economic thinking opens up new questions and new ways of approaching old questions which can add knowledge about how choice is enacted in contemporary health professions education.

Abstract
AIMS Immunocompromised mice are extensively used in the screening of vaccines and drugs for Cryptosporidium, but this study model does not reflect the real status of infection in immunocompetent animals. This study aimed to provide an optimized animal model for future studies of Cryptosporidium vaccine. METHODS AND RESULTS Three mouse strains (ICR, BALB/c and KM) with or without immunosuppression were compared after challenge with Cryptosporidium tyzzeri (C tyzzeri). The results indicated that ICR mice shed a greater number of faecal oocysts (20 346 ± 203 oocysts/g) compared with BALB/c (2077 ± 142 oocysts/g) and KM mice (3207 ± 431 oocysts/g) after experimental infection with C tyzzeri (P < .001). However, ICR mouse model is uniquely effective for C tyzzeri, not for other Cryptosporidium spp. such as C parvum. ICR mice were then used to determine the immunoreactions and immunoprotection of P23-DNA vaccine (pVAX1-P23) to C tyzzeri experimental infection. The results showed that a significant increase in anti-P23 antibody levels was induced by the pVAX1-P23 vaccine. Compared to pVAX1, TB and blank control mice, pVAX1-P23 immunized mice produced specific spleen cell proliferation as well as enhanced IL-5, IL-12p70 and IFN-γ production in sera. After challenge with 5 × 106 C tyzzeri oocysts, the oocyst shedding of the pVAX1-P23 immunized group was reduced by 69.94% comparing to the infection control. CONCLUSION These results provide an optimized animal model for the study of prophylactic vaccines and this model might be applied to other candidates against Cryptosporidium, not only for pVAX1-P23.

Abstract
Objective: To compare the clinical efficacy of different doses of rabbit antithymocyte globulin (rATG) in haplo-HSCT in the treatment of hematologic malignancies. Methods: Malignant hematological patients treated at our hospital from March 2013 to December 2018 were retrospectively analyzed. These patients were divided into three groups as per three doses of ATG (6 mg/kg, 7.5 mg/kg, and 9 mg/kg) in the conditioning regimens. The transplant outcomes were compared in terms of the occurrence of acute graft versus host disease (GVHD) , infection, and survival. Results: ①Total 288 patients were enrolled in the study, including 182 men and 106 women, with a median age of 18 (6-62) years. Total 110 patients were diagnosed with acute lymphoblastic leukemia (ALL) , 128 with acute myelogenous leukemia (AML) , 8 with chronic myeloid leukemia (CML) , 28 with myelodysplastic syndrome (MDS) , and 14 with mixed cell leukemia (MAL) . There were 159 patients in the ATG-6 group, 72 in the ATG-7.5 group, and 57 in the ATG-9 group. The median follow-up time of post transplantation was 14 (0.2-74) months. ②The incidence of neutrophil engraftment (96.9% , 97.2% , and 96.5% , respectively) and platelet engraftment (92.5% , 87.5% , and 86% , respectively) did not significantly differ among the ATG-6, ATG-7.5, and ATG-9 groups (P=0.972, P=0.276) . The incidence of grades 2-4 acute GVHD was 14.5% , 11.1% , and 8.8% in the three groups, respectively (P=0.493) , chronic GVHD incidence in the three group was 8.8% , 14.3% and 12.0% , respectively (P=0.493) . The infection rates of CMV and EBV in the ATG-9 group (77.2% and 12.5% ) were significantly higher than those in the ATG-6 (43.3% and 3.5% ) , and ATG -7.5 group (44.4% and 1.5% ) (P<0.001 and P=0.033, respectively) . ③Among the three groups, there were no significant difference in the 3-year overall survival [68.5% (95% CI 60.3% -77.9% ) , 60.1% (95% CI 48.3% -74.8% ) , 64.7% (95% CI 51.9% -80.7% ) ], cumulative incidences of relapse [34.6% (95% CI 34.3% -35.1% ) , 38.0% (95% CI 37.3% -38.7% ) , 20.6% (95% CI 20.0% -21.3% ) ], disease-free survival [53.3% (95% CI 44.9% -63.4% ) , 51.9% (95% CI 41% -65.8% ) , 63.9% (95% CI 51.9% -78.7% ) ] and non-relapse mortality [24.2% (95% CI 23.8% -24.5% ) , 26.0% (95% CI 25.4% -26.6% ) , 23.6% (95% CI 26.3% -28.2% ) ] (P=0.648, P=0.165, and P=0.486 and P=0.955) . Conclusion: Low dose (6 mg/kg) of rATG may increase the risk of grade Ⅱ-Ⅳ aGVHD, and a high dose (9 mg/kg) of ATG could significantly increase the risk of CMV and EBV infection. Median dose (7.5 mg/kg) of ATG is expected to reduce the incidence of moderate to severe aGVHD and viral infections without increasing the mortality.

Abstract
Parotid lymph node (PLN) metastasis greatly worsens the prognosis of patients with oral squamous cell carcinoma (OSCC) and poses a great challenge for further treatment of OSCC. The clinicopathological characteristics and treatment strategies for PLN metastasis from OSCC need to be comprehensively elucidated. A retrospective review of OSCC patients who experienced postoperative PLN metastasis in our department between 2000 and 2018 was performed in this study. A total of 47 OSCC patients with postoperative PLN metastasis were identified. PLN with metastasis were divided into three groups based on the location: parotid tail (PLN-t), superficial lobe (PLN-sl), and deep lobe (PLN-dl). Most of the patients experienced PLN metastasis within less than 12 months after the primary surgery for OSCC. Comparatively, patients with PLN-sl metastasis were more prone to have infiltration of the facial nerve. The tongue and buccal mucosa were the most frequent primary sites associated with PLN metastasis from OSCC. PLNs in the parotid tail were most commonly affected by the metastasized OSCC. Consequently, we recommend a series of strategies for the prevention and treatment of PLN metastasis for OSCC patients. In conclusion, PLNs should not be overlooked during preoperative evaluation and postoperative follow-up examinations for OSCC patients.

Abstract
Objective: To clarify the endoscopic changes prior to corticosteroid therapy in Cronkhite-Canada syndrome (CCS) patients and to explore the correlation between endoscopic features and clinical characteristics. Methods: A total of 24 CCS patients who were hospitalized in Peking Union Medical College Hospital from January 1999 to June 2019 and underwent gastroscopy and colonoscopy before corticosteroid therapy were retrospectively enrolled. The endoscopic images were re-interpreted. The demographic characteristics, clinical manifestations, laboratory tests and histopathological data were collected and analyzed. Results: Of all 24 patients, 15 (62.5%) were male and 9(37.5%) were female, with an average age of (59±10) years and disease course of 6 (1~36) months. Based on the endoscopic findings, the percentages of stomach, colon, duodenum, rectum and terminal ileum involvement were 100%, 100%, 95.7%, 66.7% and 50.0% respectively. Gastric involvement was more severe in the lower part of the body and the antrum of the stomach, while the cardia and the fundus were spared in 5 (20.8%) cases. Colonic involvement was more severe in the right colon. No patient showed remarkable esophageal involvement. The typical appearance under endoscopy were diffuse mucosal hyperemia and edema with polyps or nodular changes. The lesions may have mulberry-like or imbricate changes in severe cases. Lymphatic dilation in the duodenum was found in 47.8% patients. Most of the polyps were pedunculated or sub-pedunculated, with occasionally seen sessile polyps in the colon. The pit patterns of the 12 resected colon polyps in 11 patients could be classified as Kudo type Ⅲ(S), Ⅲ(L), Ⅳ and Ⅴ(I), among which 2 tubular adenomas had the Kudo type Ⅲ(L). Other resected polyps were hyperplastic polyps or CCS polyps. The disease duration prior to diagnosis was positively correlated with the maximum diameter of colon polyps (r=0.625, P=0.006). Serum albumin levels in patients with whole stomach involvement were significantly lower than those in patients with cardia spared [(29±8) g/L vs (37±5) g/L, P=0.034]. Conclusions: The typical initial endoscopic finding of CCS is multiple polyps or nodular changes on the background of diffuse hyperemia and edema lining the gastric, duodenal and colonic mucosa. Lymphatic dilatation in the duodenum could also be found. Some endoscopic features are correlated to clinical characteristics.

Abstract
Squamous cell carcinoma (SCC) of the parotid gland is a rare aggressive malignancy with a poor prognosis. The clinical behaviour, histopathological characteristics, and treatment strategies for parotid SCC still need to be comprehensively demonstrated. In this study, a retrospective review of patients diagnosed with parotid SCC was performed, covering the past two decades. Twenty-nine patients with primary parotid SCC and 10 patients with recurrent parotid SCC were identified. The clinicopathological characteristics of parotid SCC were summarized. Imaging records were used to determine the extent of invasion of the parotid SCC. Histopathological alterations in the parotid resulting from the infiltration of SCC were demonstrated. A set of treatment strategies was developed, involving parotidectomy, neck dissection, facial nerve treatment, defect repair, adjuvant radiotherapy, and chemotherapy/targeted therapy. The median patient survival was 24 months for those with primary parotid SCC and 14.5 months for those with recurrent parotid SCC. Comparatively, patients with a larger tumour size of primary parotid SCC experienced poorer overall survival (hazard ratio 8.986; P=0.013). Great efforts have been made over the past two decades to identify and treat parotid SCC. Consensus regarding therapeutic options for parotid SCC has not been widely achieved and there is still a great need for well-designed prospective studies.

Abstract
Objective: To investigate the clinicopathological characteristics and outcomes of a series of ovarian metastases of pancreatic ductal adenocarcinoma. Methods: Data of clinical manifestation, pathological characteristic, treatment and follow-up result from ten patients with ovarian metastases of pancreatic ductal adenocarcinoma confirmed by pathology were retrospectively analyzed. Results: The median age of onset was 46 years (38~79 years). The primary tumors were located in the body and tail of the pancreas in 8 cases. Bilateral ovarian metastasis occurred in 8 patients at the time of diagnosis. The median time from patients with clinical symptom to ovarian metastases was 2.5 months (0~12 months). Peritoneal metastasis was found in all of 10 cases. Nine cases were accompanied by CA125 elevation. The major features of metastatic carcinoma in the ovary were cystic-solid appearance (8 cases) and mucinous adenocarcinoma (6 cases) with no obvious immunohistochemical features in pathological observation. All patients underwent palliative ovariectomy at onset, and one patient underwent primary tumor resection simultaneously. Seven patients received chemotherapy. The median survival time of the 10 patients was 10.3 months. Conclusions: Ovarian metastases of pancreatic ductal adenocarcinoma are easily misdiagnosed. The final diagnosis depends on clinical manifestations, imaging and histopathological observation. Ovariectomy may be associated with better outcome.

VOYAGE 1 and VOYAGE 2 are two ongoing Phase 3, randomized, double-blind, placebo (PBO)/active comparator-controlled clinical trials of GUS in patients (pts) with moderate-to-severe psoriasis (PsO).Objectives:This post-hoc analysis reports pooled results through 4 years among a subgroup of moderate-to-severe PsO pts with self-reported psoriatic arthritis (PsA) at baseline.Methods:1829 pts were randomized to GUS 100 mg at Weeks (Wks) 0, 4, and 12, then every 8 wks (q8wk); PBO at Wks 0, 4, and 12, GUS at Wks 16 and 20 then q8wk; or adalimumab (ADA) 80 mg at Wk 0, 40 mg at Wk 1, then 40 mg q2wk until Wk 47 (VOYAGE 1) or Wk 23 (VOYAGE 2). In VOYAGE 1, all pts received open-label GUS 100 mg q8wk during Wks 52-204. VOYAGE 2 incorporated a randomized withdrawal study design, followed by open-label GUS during Wks 76-204. Pooled subgroup analyses using the combined GUS group were conducted based on self-reported PsA status at baseline. Efficacy based on Investigator Global Assessment (IGA) score and Psoriasis Area and Severity Index (PASI) response was assessed using prespecified treatment failure rules (nonresponder status for all time points after discontinuing due to lack of efficacy, worsening of PsO, or use of a prohibited treatment).Results:For pooled VOYAGE 1 and VOYAGE 2 pts (N=1721), combined GUS and ADA to GUS response rates at Wks 100, 156, and 204 were: PASI 90 80.6%, 80.0%, and 80.4%; PASI 100 50.1%, 49.9%, and 52.2%; IGA 0/1 83.6%, 83.3%, and 81.7%; and IGA 0 54.3%, 52.9%, and 53.9, respectively. In the pooled subgroup analysis of pts with and without PsA, response rates were similar across the Wk 100, Wk 156, and Wk 204 evaluations (Table). Rates of adverse events through Wk 204 were comparable for pts with PsA vs those without PsA at baseline.Conclusion:Among GUS-treated pts with moderate-to-severe PsO with and without self-reported PsA at baseline, stable, durable, and high levels of skin responses, as well as comparable safety outcomes, through 4 years were observed.Table.Pooled GUS Response RatesWithout PsA at BaselineWith PsA at BaselineWk 100Wk 156Wk 204Wk 100Wk 156Wk 204N=1301N=1239N=1191N=289N=276N=264PASI 901049(80.6%)1001(80.8%)964(80.9%)233(80.6%)211 (76.4%)206(78.0%)PASI 100648(49.8%)631(50.9%)635(53.3%)149(51.6%)125 (45.3%)125 (47.3%)N=1300N=1235N=1189N=288N=276N=264IGA 0/11086(83.5%)1042(84.4%)979(82.3%)241(83.7%)217 (78.6%)208(78.8%)IGA 0702(54.0%)664(53.8%)649(54.6%)160(55.6%)135 (48.9%)134(50.8%)Acknowledgments:NoneDisclosure of Interests:Kristian Reich Grant/research support from: Janssen Research & Development, LLC, Jan Dutz Grant/research support from: Janssen Research & Development, LLC, Peter Foley Grant/research support from: Janssen Research & Development, LLC, Diamant Thaçi Grant/research support from: Janssen Research & Development, LLC, Ronald Vender Grant/research support from: Janssen Research & Development, LLC, Michael Song Employee of: Janssen Research & Development, LLC, Megan Miller Employee of: Janssen Research & Development, LLC, Yin You Employee of: Janssen Research & Development, LLC, Shu Li Employee of: Janssen Research & Development, LLC, Yaung-Kaung Shen Employee of: Janssen Research & Development, LLC, April Armstrong Grant/research support from: Janssen Research & Development, LLC

Abstract
We demonstrated that a large primary and a small untreated distant breast cancer could be controlled by local treatment with our light-activatable paclitaxel (PTX) prodrug. We hypothesized that the treated tumor would be damaged by the combinational effects of photodynamic therapy (PDT) and locally released PTX and that the distant tumor would be suppressed by systemic antitumor effects. Syngeneic rat breast cancer models (single- and two-tumor models) were established on Fischer 344 rats by subcutaneous injection of MAT B III cells. The rats were injected with PTX prodrug (dose: 1 umole kg-1 , i.v.), and tumors were treated with illumination using a 690-nm laser (75 or 140 mW cm-1 for 30 min, cylindrical light diffuser, drug-light interval [DLI] 9 h). Larger tumors (~16 mm) were effectively ablated (100%) without recurrence for >90 days. All cured rats rejected rechallenged tumor for up to 12 months. In the two-tumor model, the treatment of the local large tumor (~16 mm) also cured the untreated tumor (4-6 mm) through adaptive immune activation. This is our first demonstration that local treatment with our PTX prodrug produces systemic antitumor effects. Further investigations are warranted to understand mechanisms and optimal conditions to achieve clinically translatable systemic antitumor effects.

Abstract
BACKGROUND AND PURPOSE Hereditary sensory and autonomic neuropathies (HSANs) are a group of clinically and genetically heterogeneous neurological disorders characterized by sensory dysfunctions. Here, 21 affected Chinese families are reported, including 19 with congenital insensitivity to pain with anhidrosis (CIPA; namely HSAN IV) and two with congenital insensitivity to pain (CIP; namely HSAN IID) caused by biallelic variations in NTRK1 and SCN9A, respectively, aiming to identify causative variants in these families and compare how different variants in NTRK1 affect the function of tropomyosin receptor kinase A (TrkA). METHODS Recombinant plasmids harboring the wild-type and six mutant alleles (p.Gln216*, p.Glu584Lys, p.Leu595Arg, p.Pro684Leu, p.Val709Leu and p.Arg765Cys) of NTRK1 cDNA were constructed and transfected into HEK293 cells. RESULTS The results suggested that the five missense variants only presented a subtle influence on the expression level and glycosylation of TrkA but compromised the receptor phosphorylation. Our findings also suggested that a synonymous variant c.219C>T in NTRK1 may cause aberrant splicing, indicating a potential novel pathogenic mechanism of CIPA. Furthermore, gross deletion of SCN9A was first associated with CIP. CONCLUSIONS This study identified multiple forms of variants responsible for CIPA/CIP in the Chinese population and might provide new insights into the pathogenesis of CIPA.

Abstract
Background: Work productivity loss (WPL) is a major contributor to the indirect costs of psoriasis. Newer biologic therapies are effective at reducing disease symptoms and improving quality of life, but their impact on WPL and associated indirect cost savings compared to previously approved biologic therapies is largely unknown.Objectives: To compare the effects of guselkumab and adalimumab on WPL and associated indirect cost savings in patients with moderate-to-severe psoriasis.Methods: Using data from the VOYAGE 1 (NCT02207231) trial, improvements from baseline in Dermatology Life Quality Index (DLQI) work/study domain scores were compared for patients receiving guselkumab or adalimumab at 24 and 48 weeks of treatment. Improvements in WPL and associated cost savings were calculated using a previously established DLQI-WPL algorithm.Results: Among patients who could not work/study at baseline (DLQI work/study domain score = 3), a significantly greater proportion of guselkumab-treated patients could work/study without problems (DLQI work/study domain score = 0) than adalimumab-treated patients at Weeks 24 and 48. Improvements from baseline in WPL and associated cost savings were greater with guselkumab than with adalimumab at Week 48.Conclusions: Guselkumab was superior to adalimumab for improvement in WPL and associated indirect cost savings, and its use may reduce the economic burden of psoriasis.

Abstract
Photodynamic therapy (PDT) has become an effective treatment for certain types of solid tumors. The combination of PDT with other therapies has been extensively investigated in recent years to improve its effectiveness and expand its applications. This focused review summarizes the development of a prodrug system in which anticancer drugs are activated locally at tumor sites during PDT treatment. The development of a singlet-oxygen-sensitive linker that can be conveniently conjugated to various drugs and efficiently cleaved to release intact drugs is recapitulated. The initial design of prodrugs, preliminary efficacy evaluation, pharmacokinetics study, and optimization using quantitative systems pharmacology is discussed. Current treatment optimization in animal models using physiologically based a pharmacokinetic (PBPK) modeling approach is also explored.
