Abstract
Objective: To evaluate the relationship between serum folate and the prognosis of cervical intraepithelial neoplasia grade I (CIN1) and the interaction between folate and high risk human papillomavirus (HR-HPV) infection. Methods: From a community-based married women cohort established in Jiexiu and Yangqu County of Shanxi Province from June to December 2014, a total of 564 eligible women with CIN1 by pathologically diagnosed were recruited. The pathological examination was performed again 12 months later. According to the prognosis of CIN1, participants were divided into CIN1 regression group, persistence and progression group, respectively. Nested case-control study was used to explore the relationship between serum folate and CIN1 prognosis, and additive model was used to analyze the interaction between serum folate and HR-HPV infection. Results: Among 564 CIN1 patients, 479 cases underwent pathological examination again, 331 were divided in CIN1 regression group and other 148 in persistence and progression group. The levels of serum folate in CIN1 regression group and persistence and progression group were (18.890±8.360) and (15.640±5.550) nmol/L, respectively, and the difference was statistically significant (Z=-6.937, P<0.001). HPV infection was detected in 154 patients, including 148 cases of HR-HPV infection and 6 cases of low risk human papillomavirus (LR-HPV) infection. Univariate analysis showed that there were significant differences in the age, passive smoking, frequency of pudendal cleaning, frequency of cleaning after sex, frequency of changing underwear, serum folate and HR-HPV infection between regression group and persistence and progression group (P<0.05). Multivariate logistic regression analysis showed that the frequency of pudendal cleaning (OR=0.422, 95%CI: 0.238-0.750), frequency of changing underwear (OR=0.574, 95%CI: 0.355-0.928), serum folate (13.06-16.78nmol/L: OR=4.806, 95%CI: 2.355-9.810; ≤13.05nmol/L: OR=8.378, 95%CI: 4.024-17.445), HR-HPV infection (OR=1.852, 95%CI: 1.170-2.933) were the independent influencing factors of CIN1 prognosis. Interaction analysis showed that the relative excess risk of low serum folate level and HR-HPV infection for the CIN1 persistence and progression was 4.992 (95%CI: 0.189-9.796), attributable proportion due to interaction was 0.552 (95%CI: 0.279-0.824), synergy index was 2.632 (95%CI: 1.239-5.588), aOR of serum folate≤16.78 nmol/L and HR-HPV infection positive was 9.055 (95%CI: 4.878-16.807). Conclusion: Low serum folate level could increase the risk of CIN1 persistence and progression, and might enhance the risk when combined with HR-HPV infection.

Background
We examined changes in quality of life (QOL) of patients after transcatheter aortic valve implantation (TAVI).
Methods
We conducted an observational cohort study of consecutive patients who had TAVI between 2016-2019 in British Columbia, Canada. QOL was measured at baseline, 30-day and 1-year using the Kansas City Cardiomyopathy Questionnaire (KCCQ-OS). We used linear regression modelling to examine factors associated with 30-day changes in QOL, logistic regression modelling to identify predictors of having a poor outcome, and Cox regression modelling to ascertain risk estimates of the effect of QOL on 1-year mortality.
Results
The cohort included 1,706 patients [742 women (43.5%)]; median [interquartile range, IQR] age 83 (77,86). Median (IQR) baseline KCCQ-OS was 45 (28.2,67), indicating severe impairment. Patients alive at 1-year (91.3%) reported a mean improvement of 24.1 (95% CI, 22.7-25.6) points in the KCCQ-OS at 30-day, which was sustained at 1-year (25.3; 95% CI, 23.8,26.8). Older age, lower baseline health status, lower aortic valve gradient, lower hemoglobin, atrial fibrillation and non-transfemoral access were associated with worse 30-day QOL. At 1-year, 65% of patients had a favourable outcome; additional risk factors for 1-year mortality (8.7%) were male sex, NYHA Class IV, severe pulmonary and renal disease, diabetes, and in-patient status.
Conclusions
TAVI is associated with significant early improvement in QOL which is sustained at 1 year in a "real world" registry. The inclusion of QOL can support treatment decision and the patient-centred evaluation of TAVI

Abstract
Objective: To explore the effect of dietary water-soluble vitamins on the poor prognosis of low-grade cervical intraepithelial neoplasia (CINⅠ). Methods: A total of 564 participants with CINⅠ were selected from a community-based married women cohort established in 2014. The general baseline information was collected, and HPV genotyping was detected. A food frequency questionnaire was used to investigate dietary water-soluble vitamins' consumption and determine their exposure levels. The follow-up program was carried out for 12 months, and the regression, persistence, and progression of CINⅠ was determined according to histopathological results at 12-month. Results: The low-levels of dietary water-soluble vitamins could promote CINⅠ's persistence and progression, showing the increasing tendency of CINⅠ poor prognosis with the decrease of water-soluble vitamin levels. Especially folate, VB1, VB2, VB6, niacin, biotin, and VC (RR values were 15.22, 1.86, 1.92, 2.11, 2.98, 2.14, 2.19, respectively) played an important role. Considering the status of high-risk human papillomavirus (HR-HPV) infection, our results showed that the low levels of folate, niacin, biotin could promote the poor prognosis of CINⅠ. Conclusions: The low-level of dietary water-soluble vitamins could facilitate the poor prognosis of CINⅠ. In addition, folate, niacin, biotin were more effective on HR-HPV positive women.

Abstract
Objective: To investigate the diagnostic value of different vaginal micro-environmental factors in low-grade cervical intraepithelial neoplasia (CIN Ⅰ) and determine the optimal model in high-risk human papillomavirus (HR-HPV) infection. Methods: A total of 926 women, including 623 with normal cervical (NC) condition and 303 CINⅠ patients, had undergone pathological examinations, and were enrolled in the study. All the women were from a community previously established cohort. Vaginal cleanliness, pH, H2O2, β-glucuronidase, coagulase, sialidase, and leukocyte esterase (LE) were detected by the combined detection method aerobic vaginitis/bacterial vaginosis in vaginal secretions. HPV genotyping was performed by using the flow-through hybridization technology. The data were analyzed by SAS 9.2 and SPSS 23.0. Results: The vaginal cleanliness, pH, sialidase, and LE were determined as the representative vaginal micro-environment factors by principal component analysis. Based on logistic regression theory to analyze the ROC curve, the results showed that the highest sensitivity was with pH value (76.2%), and the highest specificity was with sialidase (90.9%). The area under ROC curve were higher in combination detection modes of sialidase+LE (0.714), pH+sialidase+LE (0.719), vaginal cleanness+sialidase+LE (0.713) and pH+vaginal cleanness+sialidase+LE (0.709). According to HR-HPV infection status, the TOPSIS method was used to analyze the combined detection optimal model. Specifically, we found that the best diagnostic model was pH+sialidase +LE (Ci=0.585) in the HR-HPV positive group and vaginal cleanness+sialidase+LE (Ci=0.641) in the negative group. Conclusions: The combined detection of vaginal microenvironment factors could be used for auxiliary diagnosis for CINⅠ. It would be more effective when detecting pH, sialidase, and LE in HR-HPV positive women while vaginal cleanness, sialidase, and LE in HR-HPV negative women at the same time.

Abstract
Objective: To describe the characteristics of high-risk human papillomavirus (HR-HPV) infection and its influences by vaginal micro-environmental factors. Methods: A total of 421 women with HR-HPV infection and normal cervix diagnosed by pathology were selected from a community cohort established earlier by our research group for a 24-month follow-up. The baseline data were collected at enrollment. The vaginal micro-environmental factors were detected by using the combined detection kit of aerobic vaginitis and bacterial vaginosis. And the HPV was detected by using the flow-through hybridization technology. According to the HR-HPV infection status in baseline and 24 months of follow-up, with the prognosis characteristics of HR-HPV infection described, the impact of vaginal micro-environmental factors on the prognosis of HR-HPV infection was explored as well. Results: Among 390 HR-HPV infected women who completed 24 months of follow-up, the top five types of persistent HR-HPV infection rate appeared as HPV16 (24.1%), HPV58 (22.2%), HPV53 (21.7%), HPV52 (20.0%), and HPV39 (11.8%), respectively. The results showed that women with abnormal vaginal pH (aOR=1.74, 95%CI: 1.08-2.80), abnormal neuraminidase (aOR=2.70, 95%CI: 1.52-4.83), or abnormal leucocyte esterase (aOR=3.41, 95%CI: 2.13-5.44), the risk of HR-HPV persistent infection increased. The abnormalities of neuraminidase and leukocyte esterase could increase the risk of persistent infection of homotype and heterotypic HR-HPV. Conclusions: HPV16 was prone to persistent infection. Abnormalities of vaginal pH, neuraminidase, and leukocyte esterase might increase the risk of HR-HPV persistent infection. Both the abnormalities of neuraminidase and leukocyte esterase play an essential role in the HR-HPV persistent infection.

Abstract
Objective: To analyze the association of the cadmium internal exposure with chronic kidney disease (CKD) in Chinese adults aged 18 and older. Methods: A total of 9 821 adults aged 18-79 from the China National Human Biomonitoring (CNHBM) from 2017 to 2018 were included. Blood and urine cadmium exposure levels were measured by inductively coupled plasma mass spectrometry (ICP-MS), and urine cadmium levels were adjusted with urine creatinine; CKD were defined by estimated glomerular filtration (eGFR) using the chronic kidney disease epidemiology collaboration (CKD-EPI). Weights were considered due to complex sampling process for in statistical analysis. Logistic regression is used to analyze the association of blood cadmium, urine cadmium, and urine cadmium adjusted with creatinine exposure levels with CKD, and restricted cube spline (RCS) was used to assess the exposure-response curve of blood cadmium, urine cadmium and urine cadmium adjusted with creatinine with CKD. Results: The weighted age was 44.75 and males accounted for 61.1%. The prevalence rate of CKD was 12.7%. The geometric mean values of blood cadmium, urine cadmium, and urine cadmium adjusted with creatinine were 0.96 μg/L, 0.61 μg/L, and 0.58 μg/g. After adjusting for confounding factors, the weighted logistic regression showed that the lowest quintile (Q1) was compared with the odds ratio (OR) of the highest quintile (Q5) of blood cadmium, urine cadmium, and urine cadmium adjusted with creatinine and the 95% confidence interval (CI) was 1.80 (1.02-3.20), 1.77 (0.94-3.31) and 1.94 (1.11-3.37) respectively. In the restricted cubic spline regression model, non-linear association of blood cadmium, urine cadmium, and urine cadmium adjusted with creatinine with CKD were observed after adjusting for related confounding factors (P<0.001, 0.018, 0.031 respectively). The risk of CKD increased with the increment of cadmium exposure without risk threshold, and the exposure response curve was steeper at low cadmium exposure. Conclusions: Among Chinese adults aged 18 and older, cadmium exposure is positively associated with the risk of chronic kidney disease.

Abstract
Diffuse large B-cell lymphoma (DLBCL) is the most frequent and commonly diagnosed subtype of NHL, which is characterized by high heterogeneity and malignancy, and most DLBCL patients are at advanced stages. The serine/threonine kinase NEK2 (NIMA-related kinase 2), a member of NIMA-related kinase (NEK) family that regulates cell cycle, is upregulated in a variety of malignancies, including diffuse large B-cell lymphoma. However, the role and underlying mechanisms of NEK2 in DLBCL have seldom been discussed. In this study, we identified that NEK2 is upregulated in DLBCL compared to normal lymphoid tissues, and overexpression of NEK2 predicted a worse prognosis of DLBCL patients. Gene set enrichment analysis indicates that NEK2 might participate in regulating glycolysis. Knockdown of NEK2 inhibited growth and glycolysis of DLBCL cells. The interaction between NEK2 and PKM2 was discovered by tandem affinity purification and then was confirmed by immunofluorescence staining, coimmunoprecipitation, and immunoprecipitation. NEK2 bounds to PKM2 and regulates PKM2 abundance via phosphorylation, which increases PKM2 stability. The xenograft tumor model checks the influence of NEK2 on tumor growth in vivo. Thus, NEK2 could be the novel biomarker and target of DLBCL, which remarkably ameliorates the diagnosis and treatment of DLBCL.

Abstract
Chronic obstructive pulmonary disease (COPD) represents a chronic inflammatory disorder of the airways induced mainly by cigarette smoking. In the current study, cigarette smoke extract (CSE) was used to develop an in vitro COPD model using human bronchial epithelium (HBE) cells to expound the possible role of microRNA-29b (miR-29b) in COPD. Firstly, miR-29b and interleukin (IL)-22 expression was assessed in serum of 20 healthy non-smokers, 20 healthy smokers and 20 COPD patients as well as CSE-treated HBE cells. Then, miR-29b and IL-22 expression was altered to evaluate their functions in Th17/Treg ratio. miR-29b inhibited Th17/Treg ratio and levels of IL-22; whereas overexpression of IL-22 reversed these trends. Moreover, rescue experiments found that IL-22 neutralized the repressive effects of miR-29b on Th17/Treg ratio and inflammatory response. Finally, we found that miR-29b blocked the JAK/STAT3 pathway in CSE-treated HBE cells. These data highlighted that miR-29bs modulated Th17/Treg imbalance in CSE-induced experimental COPD through inhibition of IL-22-dependent JAK/STAT3 pathway.

Abstract
Objective: To explore the effects of hnRNP E1 on the expression of early genes E2, E6 of HPV16 and the biological function in cervical cancer SiHa cell lines. Methods: The cell experiments in vitro were carried out in cervical cancer cell lines SiHa. The expression levels of E2, E6 mRNA and protein of HPV16 were detected by Real-time PCR and Western blot, respectively, before and after up-regulating hnRNP E1. Meanwhile, the cell proliferation, cycle and apoptosis were evaluated by CCK-8 and flow cytometry. Data analyses were performed using SPSS 22.0 and Graphpad Prism 7.0 software. Results: Compared with the blank and the blank plasmid group, the cells activity and proliferation decreased at 24, 48 and 72 h after up-regulating hnRNP E1 (P<0.05), while the percentage of cells in G0/G1 phase increased and the percentage in S and G2/M phase and proliferation index decreased (P<0.05). Moreover, the late apoptotic rate and the total apoptotic rate increased (P<0.05). The expression levels of E6 mRNA and protein of HPV16 in hnRNP E1 up-regulated group were significantly lower than that in both blank group and blank plasmid group, the differences were significant (P<0.05), showing the tendency of cells proliferation index decrease and total apoptotic rate increase with decreased HPV16 E6 expression. There were no significant differences in the expression of E2 mRNA of HPV16 among the three groups (P=0.427), and no E2 protein of HPV16 was detected. Conclusions: hnRNP E1 could inhibit the transcription and translation of E6 oncogene of HPV16 and further inhibit the proliferation and promote apoptosis of cervical cancer cells, suggesting that hnRNP E1 might be a potential target marker to prevent cervical lesions. But no association between hnRNP E1 and HPV16 E2 was found in SiHa cells.

Abstract
Objective: To study the relations of human papillomavirus (HPV) infection, vaginal micro-environmental disorder with cervical lesion. Methods: A total of 1 019 women including 623 with normal cervical (NC), 303 with low-grade cervical lesion (CIN Ⅰ) and 93 with high-grade cervical lesion (CIN Ⅱ/Ⅲ) were enrolled in this study from the communities in Shanxi province, China. Case-control method was adopted, with NC as the control group and CIN as the case group. Related information was collected including demographic characteristics and relevant factors related to cervical lesions. HPV genotypes were detected by flow-through hybridization technology. Vaginal pH was detected by the pH test paper. Vaginal H(2)O(2) was detected by the combined detection kit of aerobic vaginitis and bacterial vaginosis. Vaginal cleanliness was detected by smear method. Results: Data from the unconditional logistic regression analysis showed that HPV infection (CINⅠ: aOR=1.39, 95%CI: 1.01-1.90; CINⅡ/Ⅲ: aOR=11.74, 95%CI: 6.96-19.80), H(2)O(2) (CINⅠ: aOR=2.09, 95%CI: 1.47-2.98; CINⅡ/Ⅲ: aOR=4.12, 95%CI: 2.01-8.43), cleanliness (CIN Ⅱ/Ⅲ: aOR=2.62, 95%CI: 1.65-4.14), and composite indicators (CINⅠ: aOR=1.67, 95%CI: 1.24-2.25; CINⅡ/Ⅲ: aOR=4.24, 95%CI: 2.30-7.81) all had increased the risk of cervical lesion and the trend on the severity (P<0.001) of cervical lesions. Additionally, we observed a synergic effect between HPV infection and vaginal micro-environmental composite indicator in CINⅡ/Ⅲ. With or without HPV infection, the ORs value of CINⅠ caused by vaginal micro-environment disorder remained close. Conclusions: Results from our study revealed that vaginal micro-environmental composite indicator could increase the risk for cervical lesion, in particular with the high-grade ones which all posed stronger risks when combined with HPV infection. However, the role of vaginal micro-environment disorder in the occurrence of CIN Ⅰ should not be ignored.

Abstract
In this study, a rabbit endometritis model was developed to study cow endometritis. In addition, the protective effects of baicalin (a flavonoid) against endometritis were investigated. Clinical symptoms, differential leukocyte counting, uterine secretion smear microscopy and chemical examination, urine testing, and signs of necropsy showed abnormal changes and inflammatory responses in the uterus of rabbits. Histopathological results revealed visible inflammatory exudates and blood spots between intercellular spaces which confirmed that the rabbit endometritis model was successfully developed. Most importantly, these inflammatory signs were partially attenuated with baicalin treatment. The data revealed that the increased body temperature and leukocyte cells, pus, and the detachment of epithelial cells were alleviated with baicalin administration in a dose-dependent manner. Histopathological tissue changes such as inflammatory cells infiltrates, hyperemia, hemorrhages, and shedding of epithelial cells were partially attenuated with baicalin treatment. In addition, the mRNA expression of inflammation-related genes (iNOS, IL-1β, TNF-α, IL-10, IL-4, and IL-6) was significantly altered in RAW264.7 cells after LPS treatment. Further, the phosphorylated protein expression of JNK, p65, and IκBα were significantly reduced with LPS treatment. Intriguingly, baicalin pretreatment reversed the alteration in mRNA expression of inflammation-related genes and significantly reduced the phosphorylation of JNK, p65, and IκBα. In summary, our results suggest that baicalin has protective effects on bacterial-induced endometritis in rabbits that involve the suppression of NF-κB and JNK signaling pathways and pro-inflammatory cytokines.

Abstract
OBJECTIVES To examine the diagnostic performance of the Tilburg Frailty Indicator (TFI), 11-factor modified frailty index (mFI-11), and 5-factor modified frailty index (mFI-5) for frailty defined by Frailty Phenotype (FP), as well as to compare the predictive ability of TFI, mFI-11, and mFI-5 for adverse outcomes in hospital among elderly patients undergoing gastric cancer surgery. DESIGN A prospective cohort study. SETTING Hospitalization setting, Nanjing, China. PARTICIPANTS We recruited 259 elderly patients undergoing gastric cancer surgery from a tertiary hospital. MEASUREMENTS Frailty was assessed by the FP, TFI, mFI-11, and mFI-5 before surgery, respectively. The receiver operating characteristic (ROC) curves were plotted to compared the diagnostic performance of TFI, mFI-11, and mFI-5 using FP as the reference. ROC curves were used to examine the performance of TFI, mFI-11, and mFI-5 in predicting adverse outcomes. The area under the curve (AUC)>0.70 was regarded as an indicator of good performance. RESULTS The prevalence of frailty ranged from 8.5% (mFI-11) to 45.9% (TFI). The AUCs of TFI (AUC: 0.764, p<0.001) was significantly greater than that of mFI-11 (AUC: 0.600, p=0.033) and mFI-5 (AUC: 0.600, p=0.0311) in the detection of frailty defined by FP, with quite different sensitivity and specificity at their original cutoffs. TFI and mFI-11 both had statistically significant but similarly inadequate predictive accuracy for adverse outcomes in hospital, including total complications (AUCs: 0.618; 0.621), PLOS (AUCs: 0.593; 0.639), increased hospital costs (AUCs: 0.594; 0.624), and hypoproteinemia (AUCs: 0.573; 0.600). For the mFI-5, only the predictive ability for hypoproteinemia was statistically significant, with poor accuracy (AUC: 0.592, p<0.0055). CONCLUSION The TFI performed slightly better than mFI-11 and mFI-5 in our study. Moreover, future studies are needed to further determine an optimal frailty instrument with great diagnostic and predictive accuracy.

Int J Equity Health 2020; 19:212. [PMID: 33246477 PMCID: PMC7694412 DOI: 10.1186/s12939-020-01323-z] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/13/2020] [Accepted: 11/11/2020] [Indexed: 12/24/2022] Open
Abstract
Background Breast cancer (BC) is the most common cancer in women in the developed world. In order to find developing cancers in an early stage, BC screening is commonly used. In Flanders, screening is performed in and outside an organized breast cancer screening program (BCSP). However, the determinants of BC screening coverage for both screening strategies are yet unknown. Objective To assess the determinants of BC screening coverage in Flanders. Methods Reimbursement data were used to attribute a screening status to each woman in the target population for the years 2008–2016. Yearly coverage data were categorized as screening inside or outside BCSP or no screening. Data were clustered by municipality level. A generalized linear equation model was used to assess the determinants of screening type. Results Over all years and municipalities, the median screening coverage rate inside and outside BCSP was 48.40% (IQR: 41.50–54.40%) and 14.10% (IQR: 9.80–19.80%) respectively. A higher coverage rate outside BSCP was statistically significantly (P < 0.001) associated with more crowded households (OR: 3.797, 95% CI: 3.199–4.508), younger age, higher population densities (OR: 2.528, 95% CI: 2.455–2.606), a lower proportion of unemployed job seekers (OR: 0.641, 95% CI: 0.624–0.658) and lower use of dental care (OR: 0.969, 95% CI: 0.967–0.972). Conclusion Coverage rate of BC screening is not optimal in Flanders. Women with low SES that are characterized by younger age, living in a high population density area, living in crowded households, or having low dental care are less likely to be screened for BC in Flanders. If screened, they are more likely to be screened outside the BCSP.

Abstract
Background Host response diffuse large B-cell lymphoma (HR DLBCL) shares features of histologically defined T-cell/histiocyte-rich B-cell lymphoma, including fewer genetic abnormalities, frequent splenic and bone marrow involvement, and younger age at presentation. HR DLBCL is inherently less responsive to the standard treatment for DLBCL. Moreover, the mechanism of infiltration of HR DLBCL with preexisting abundant T-cells and dendritic cells is unknown, and their associated underlying immune responses incompletely defined. Here, hub genes and pathogenesis associated with HR DLBCL were explored to reveal molecular mechanisms and treatment targets. Methods Differentially expressed genes were identified in three datasets (GSE25638, GSE44337, GSE56315). The expression profile of the genes in the GSE53786 dataset was used to constructed a co-expression network. Protein-protein interactions analysis in the modules of interest identified candidate hub genes. Then screening of real hub genes was carried out by survival analysis within the GSE53786 and GSE10846 datasets. Expression of hub genes was validated in the Gene expression profiling interactive analysis, Oncomine databases and human tissue specimens. Functional enrichment analysis and Gene set enrichment analysis were utilized to investigate the potential mechanisms. Tumor Immune Estimation Resource and The Cancer Genome Atlas were used to mine the association of the hub gene with tumor immunity, potential upstream regulators were predicted using bioinformatics tools. Results A total of 274 common differentially expressed genes were identified. Within the key module, we identified CXCL10 as a real hub gene. The validation of upregulated expression level of CXCL10 was consistent with our study. CXCL10 might have a regulatory effect on tumor immunity. The predicted miRNA (hsa-mir-6849-3p) and transcription factor (IRF9) might regulate gene expression in the hub module.

Abstract
Abstract
Introduction/Objective
Schistosomiasis is extremely rare in the United States. Most patients diagnosed in the US have an international travel history or recently immigrated from endemic areas. We report a case of a 9-year-old boy who presented with a three-month history of daily abdominal pain, decreased appetite, weight loss, and microcytic anemia. The patient had alternating symptoms of constipation and diarrhea mimicking Irritable Bowel Syndrome (IBS).
Methods
CT scans showed distal sigmoid colon with wall thickening and hyperenhancement. Stool Helicobacter pylori antigen test was positive and hemoglobin levels were low (11 g/dL). The blood eosinophil count was initially within the normal range but was significantly elevated three months later (2,115 cells/µL).
Esophagogastroduodenoscopy and colonoscopy were performed, which showed patchy areas of erythema and punctate bleeding within the descending and sigmoid colon.
Results
Gastrointestinal tract biopsies revealed focal, prominent eosinophilic infiltrates in the lamina propria. There were multifocal granulomas and fibrosis surrounding Schistosoma ova in the lamina propria and submucosa of duodenum, cecum, colon, and rectum. Acid-fast stain highlights the shell and spine of the ova. A retrospective chart review revealed that the patient had traveled to Yemen one month before the onset of symptoms. Schistosomiasis is among the top differentials for marked, sustained eosinophilia, especially with relevant travel history. Distortions caused by processing and sectioning can make speciation difficult on tissue sections. Acid-fast staining of the shell would favor S. mansoni over S. intercalatum; however, the S. intercalatum-S. hematobium hybrid also has an acid fast–positive shell. The duodenum is an uncommon location to find Schistosoma ova, which are usually found in the rectum and sigmoid colon.
Conclusion
The symptoms of gastrointestinal schistosomiasis may mimic IBS, and eosinophilia may initially be not evident as in this case. However, a high degree of suspicion is required in diagnosing schistosomiasis in patients from endemic areas.

Abstract
Abstract
Introduction/Objective
Lupus podocytopathy (LP), featured by nephrotic syndrome, is a unique subtype of lupus nephritis that mimics minimal change disease or primary focal segmental glomerulosclerosis (FSGS) on renal biopsy with diffuse podocyte foot process effacement and no capillary-loop immune deposits. LP usually presents on a background of ISN/RPS class I or class II lupus nephritis, and very rarely may present without immune deposits.
Diagnosis of LP, when confounded by other glomerular diseases associated with nephrotic syndrome, can be very challenging and requires thorough clinical and pathology correlations.
Methods
Here we report a case of LP in a patient with nephrotic syndrome and multiple comorbidities affecting kidneys. A 24-year-old female with type-I diabetes, psoriasis, and intermittent arthritis/rash of unknown etiology, presented with abrupt onset of nephrotic proteinuria attributed to recent low dose prednisone therapy, and renal insufficiency. A renal biopsy showed nodular glomerulosclerosis and FSGS. No immune deposits were identified by immunofluorescence or electron microscopy. Ultrastructurally there was also diffuse glomerular basement membrane thickening and over 90% podocyte foot process effacement. With no established systemic lupus erythematosus (SLE), the case was initially diagnosed as diabetic nephropathy with coexistent FSGS as the etiologies for nephrotic proteinuria, and the patient was put on ACEI and diuretics. However, massive proteinuria persisted, and the patient also developed pancytopenia. Serology concurrent with the biopsy came out later showing positive autoantibodies against dsDNA, Smith, and Histone. With continued worsening of creatinine, a renal biopsy was repeated revealing essentially similar findings to the first biopsy.
Results
Integrating the serology results and clinical presentation, SLE was favored. The pathology findings were re- evaluated and considered to be most consistent with LP and coexistent diabetic nephropathy, with FSGS either a component of LP or an independent lesion secondary to diabetes or hypertension. The patient was started with high dose prednisone at 60 mg/day. One month later, her proteinuria, serum creatinine, pancytopenia, skin rash, and arthritis were all significantly improved.
Conclusion
LP can be easily masked by coexistent glomerular diseases. Sufficient awareness of the entity is necessary for the appropriate diagnosis and treatment.

Abstract
Abstract
Introduction/Objective
Histiocytic necrotizing lymphadenitis, also known as Kikuchi-Fujimoto disease (KFD), is a rare and benign self-limiting process primarily affecting 20~35-year-old Asian women with spontaneous remission after weeks to months of illness. Although the involvement of T cell-mediated immune response, infections, and HLA class II gene have been proposed as possible etiologies, the detailed pathogenesis has not been elucidated. Very few literatures exhibited KFD displaying chromosomal abnormality such as t(2:16).
Methods
Here, we report a rare case of KFD with novel karyotype abnormalities in a 24-year-old African American male. It presented as painless cervical lymphadenopathy for one month without fever, night sweats, or weight loss. An excisional biopsy of the lymph node (LN) was performed.
Results
Tissue culture for bacteria and flow cytometry of the LN were negative. Histopathology revealed numerous pale circumscribed foci composed of lymphocytes, histiocytes, plasmacytoid dendritic cells, and abundant karyorrhectic debris in the background of coagulative necrosis. No neutrophils or hematoxylin bodies are seen.
Immunohistochemical studies showed CD3+/CD4+ T lymphocytes, CD68+ histiocytes, and CD123+ plasmacytoid dendritic cells. Abnormal karyotype was observed as: 46, XY, del(6) (q?16q?22).
Conclusion
We present this case to demonstrate that 1. Although KFD is most prevalent in young Asian females, it may occur in both genders and other ethnical groups and perhaps represents an underdiagnosed process. 2. KFD can mimic a variety of diseases such as rheumatologic, infectious, and hematologic malignancies; a thorough workup including serology, culture, and flow cytometry is needed to exclude serious diseases such as systemic lupus erythematosus and malignancy to render an early diagnosis which may avoid unnecessary diagnostic and therapeutic interventions. 3. Cytogenic abnormalities, although observed in many malignancies, should not be used as a sole determinant of malignancy, and the interpretation needs to be in a relevant clinical and histopathological context in a multidisciplinary setting to avoid misdiagnosis and inappropriate treatment.

Abstract
OBJECTIVE Increasing evidence indicated that microRNAs (miRNAs) are crucial regulators for cancer development. Bladder cancer (BCa) is a major threat to human health. The aim of this study was to analyze the roles of miR-652-3p in BCa, and to explore the associated mechanisms. MATERIALS AND METHODS MiR-652-3p expression in BCa cell lines was explored using Real Time-quantitative Polymerase Chain Reaction (RT-qPCR) method. MiR-652-3p expression level in BCa tissues was explored at StarBase. Cell Counting Kit-8 (CCK-8) assay, wound-healing assay, and transwell invasion assay were conducted to investigate the biological roles of miR-652-3p. The underlying mechanisms of miR-652-3p in NSCLC were investigated using luciferase activity reporter assay and rescue experiments. RESULTS We showed that miR-652-3p expression level was upregulated in both BCa tissues and cell lines. The knockdown of miR-652-3p significantly inhibited BCa cell proliferation, migration, and invasion in vitro. Moreover, we showed that potassium intermediate/small conductance calcium-activated channel, subfamily N, member 3 (KCNN3) was a functional target for miR-652-3p. Besides, the expression of KCNN3 in BCa tissues was negatively correlated with miR-652-3p. CONCLUSIONS Collectively, these results showed that miR-652-3p could promote BCa cell proliferation, migration, and invasion via directly regulating KCNN3, which may provide a novel therapeutic target for BCa treatment.

Abstract
Abstract
Poly ADP ribose polymerase (PARP) inhibitors have shown promising clinical activities for patients with BRCA mutations and are changing the landscape of ovarian cancer treatment. However, the therapeutic mechanisms of action for PARP inhibition in the interaction of tumors with the tumor microenvironment and the host immune system remain unclear. We recently reported that inhibition with a PARP inhibitor (olaparib) triggers robust local and systemic antitumor immunity involving both adaptive and innate immune responses through a STING-dependent antitumor immune response in Brca1-deficient ovarian tumors. This effect is further augmented when olaparib is combined with PD-1 blockade. However, all PBM-bearing mice treated with olaparib alone or in combination with PD-1 blockade eventually succumbed to the disease. These data indicate that although multiple PARP inhibitors have been approved for the treatment of BRCA-deficient ovarian cancers, eradication of this type of cancer remains a challenge. I will discuss our recent efforts on identifying resistance mechanisms to PARP inhibition and developing potential therapeutic strategy that overcomes the resistance to improve the treatment outcome.

Abstract
Extensive use of titanium alloys is partly hindered by a lack of ductility, strain hardening, and fracture toughness. Recently, several β-metastable titanium alloys were designed to simultaneously activate both transformation-induced plasticity and twinning-induced plasticity effects, resulting in significant improvements to their strain hardening capacity and resistance to plastic localization. Here, we report an ultra-large fracture resistance in a Ti-12Mo alloy (wt.%), that results from a high resistance to damage nucleation, with an unexpected fracture phenomenology under quasi-static loading. Necking develops at a large uniform true strain of 0.3 while fracture initiates at a true fracture strain of 1.0 by intense through-thickness shear within a thin localized shear band. Transmission electron microscopy reveals that dynamic recrystallization occurs in this band, while local partial melting is observed on the fracture surface. Shear band temperatures of 1250–2450 °C are estimated by the fusible coating method. The reported high ductility combined to the unconventional fracture process opens alternative avenues toward Ti alloys toughening. Specific titanium alloys combine transformation-induced plasticity and twinning-induced plasticity for improved work hardening. Here, the authors show that these alloys also have an ultra-large fracture resistance and an unexpected fracture mechanism via dynamic recrystallization and local melting in a deformation band.
