Abstract
INTRODUCTION Research in to the pathophysiology of the complex layers of retinal and sub-retinal cells is hampered by inadequate recognition of particular cells and tissues. A comprehensive panel of antibodies recognising retinal tissues is lacking. Our purpose was to determine the value of a panel of antibodies labelling various cells in the human retina. METHOD Five groups of antibodies labelled frozen sections of retinas: (1) protein kinase C-α, Glutamine Synthetase (GS) and ionized calcium-binding adapter molecule 1 (Iba1); (2) Parvalbumin, Calretinin and glial fibrillary acidic protein (GFAP); (3) Thy1, GS and Iba1; (4) Rhodopsin, GS and Iba1; and (5) Brn3a, Rhodopsin and protein kinase C-α. The distribution of these antigens were determined by confocal microscopy and calculated grey value of each antibody in each layer of the retina by Image J. RESULTS Different antibodies determined certain retinal layers. Thy 1 is a good determinant of the ganglion cell layer, whilst GS is present in all layers except the photoreceptor layer. Brn3a is specific for the ganglion cell layer whilst parvalbumin marks the ganglion cell layer and the outer plexiform layer. Rhodopsin strongly marks the photoreceptor layer, but this is also marked weakly by GFAP. CONCLUSION The multiple labelling of human retinal cells brings further understanding of the biological characteristics and functions of these cells, and provides a theoretical basis for their possible role in diseases. In the growing field of human retina research, our data may provide a point of reference for future studies of the human retina.

Abstract
Toxoplasma gondii is a world-widely spread zoonotic parasite. However, scarce knowledge is known about the prevalence of T. gondii infection in people in Hubei province, China. This study herein was to perform epidemiological investigation of T. gondii infection in people in this region. A total 12527 blood samples were obtained during 2015-2018, and were assayed for T. gondii antibodies of IgG and IgM, respectively by employing an indirect hemagglutination test (IHA). The results discovered that the prevalence of T. gondii in people was 2.44% and 6.1%, respectively based on antibodies of IgG and IgM, respectively. The prevalence was ranged from 0.3% to 5.4% during 2015-2018 based on IgM antibodies. For genders, the prevalence was 0.7% and 2.6% in males and females, respectively based on IgM antibodies. In different years, the prevalence was ranged from 4.9% to 14.0% based on IgG antibodies. The prevalence of T. gondii was 4.9% and 6.6% in males and femalesy based on IgG antibodies. The current results may be helpful for the implementation of preventive measures against Toxoplasma infection among people living in this region.

Abstract
OBJECTIVES Antibodies against carbamylated protein (anti-CarP) were found to be a promising marker to evaluate joint damage and disease activity in patients with rheumatoid arthritis (RA). However, whether anti-CarP antibodies were present in systemic lupus erythematosus (SLE) remained ambiguous. We have therefore undertaken this study to assess the levels of serum anti-CarP antibodies and to evaluate their clinical value in SLE. METHODS Serum levels of antibodies against carbamylated-vimentin (anti-Carp) were measured by enzyme immunosorbent assay in 100 patients with SLE, 76 with RA, 17 with primary Sjögren syndrome (pSS), and 68 healthy controls. Data analyses between anti-Carp antibodies and other laboratory measures were performed using SPSS 24 software for Windows. RESULTS The levels of serum anti-CarP antibodies in patients with SLE were significantly higher than those in healthy controls. In addition, anti-CarP antibodies were present in SLE patients lacking the disease-specific antibodies, including anti-Smith-negative patients (24.4%, 21/86), anti-dsDNA-negative patients (29.3%, 12/41), anti-nucleosome-negative patients (21.4%, 9/42), and antiribosomal P protein antibody-negative patients (23.7%, 18/76). There were significant differences between the anti-CarP-positive and anti-CarP-negative SLE patients in clinical and laboratory features, such as age, erythrocyte sedimentation rate (ESR), C-reactive protein, rheumatoid factor, third-generation cyclic citrullinated peptide (CCP3), anticardiolipin, D-dipolymer, complement 3, immunoglobulin G (IgG), red blood cell count (RBC) and hemoglobin. After adjusting for age and disease duration, the high levels of anti-CarP antibodies were still correlated with low RBC, hemoglobin and high ESR, IgG and CCP3. Active SLE patients demonstrated higher anti-CarP IgG than inactive patients. Moreover, the levels of anti-CarP were significantly higher in SLE patients with arthralgia and/or arthritis than in those without joint involvement. CONCLUSIONS Anti-CarP antibodies were present in SLE patients and associated with the disease severity. These might provide a potential supplement to other specific autoantibodies for diagnosis of SLE and serve as a promising marker for measuring joint damage in the disease.

Abstract
Objective: To explore the differences in epidemiology and clinical features of Guillain- Barré syndrome (GBS) between rural and urban areas of southern China. Methods: The clinical data of 759 hospitalized GBS patients from 31 hospitals of 13 provinces/cities in southern China, between January 1st, 2013 and September 30th, 2016, were collected and analyzed retrospectively. Results: The risk of GBS was higher for males than females in rural and urban areas and the median age was 49 and 48 years, respectively. Seasonal clustering in winter and spring was noted in both rural and urban areas, and the seasonal trend was more markedly in rural areas, but the differences showed no statistical significance. There were 70.37% of patients in rural areas and 73.69% in urban areas who had antecedent respiratory infection. The median time from onset to nadir was 7 days, and Hughes Disability Scale at admission, nadir and discharge were (2.95±1.10 vs 2.84±1.15), (3.25±1.11 vs 3.14±1.21), (2.02±1.24 vs 2.00±1.31) in rural and urban areas respectively. Albuminocytologic dissociation was present in 84.34% of patients in rural areas and 84.62% of cases in urban areas. There were 8.65% and 10.94% of cases in rural and urban areas who required mechanical ventilation during hospitalization, respectively. Demyelinating GBS accounted for 53.29% and 48.77%, respectively, in patients with findings of nerve conduction studies available in rural and urban areas. Conclusions: GBS in rural areas of southern China showed male predominance and a peak of spring and winter occurrence, with respiratory infection as the predominated preceding events and demyelinating GBS being main clinical subtype. Winter and spring showed a higher incidence of GBS in rural and urban areas. There were no significant differences of sex, age, preceding events, season trend, progression of disease, clinical subtypes and cerebrospinal fluid investigations in GBS patients between rural and urban areas.

Abstract
OBJECTIVE To understand the situation of Schistosoma japonicum infections in wild animals in transmission-controlled schistosomiasis-endemic areas in Jiangxi Province, so as to provide scientific evidence for implementing precision control interventions and achieving the goal of transmission interruption and elimination of schistosomiasis. METHODS Five endemic villages from Ruichang City and Pengze County that were heavily endemic for schistosomiasis in Jiangxi Province, were selected as the study villages. Wild animals like wild mice were captured, and the livers of wild animals were purchased from the snail habitats in the study villages for detection of S. japonicum infections. In the study villages, S. japonicum human infections were screened using indirect hemagglutination assay (IHA) followed by parasitological examinations with miracidial hatching test and Kato-Katz method, and the S. japonicum infection in livestock was tested using a miracidial hatching test with a plastic tube. In addition, snail survey was conducted in the study villages by means of systematic sampling combined with environmental sampling, and the S. japonicum infection in snails was detected using a loop-mediated isothermal amplification (LAMP) assay. RESULTS A total of 240 liver specimens were sampled or purchased from 5 species of wild animals in the study villages, including wild mice, weasels, pigs, deer and rabbits. A total of 172 wild mice were captured, with a 2.91% rate of S. japonicum infection, and there was no S. japonicum infection detected in other wild animals. The prevalence of Capillaria hepatica infection was 12.21%, 1.96% and 12.50% in wild mice, deer and pigs, respectively. In addition, there was no S. japonicum infection found in either humans or livestock in the study villages, and the mean snail density varied from 0.13 to 0.80 snails/0.1 m2 in the study villages. LAMP assay detected S. japonicum infection in 2 tubes in a study village. CONCLUSIONS The role of wild animals in schistosomiasis transmission and their potential risks can not be neglected in hilly schistosomiasis-endemic areas of Jiangsu Province after transmission control. Intensified surveillance and targeted control measures should be implemented to consolidate schistosomiasis control achievements.

Abstract
Budd-Chiari syndrome (BCS) is a rare disease characterized by obstruction of hepatic venous outflow tract with diversified etiologies. Sea-blue histiocytosis (SBH) is a kind of storage diseases defined by the deposition of abundant sea-blue histiocytes in various organs and can lead to hepatosplenomegaly, cirrhosis, or even liver failure. The association between BCS and SBH has never been reported before. Here, we report a patient with BCS presenting with hepatosplenomegaly, portal hypertension, and pancytopenia who was later confirmed to also have SBH.

Abstract
van der Waals (vdW) heterostructures, which are produced by the precise assemblies of varieties of two-dimensional (2D) materials, have demonstrated many novel properties and functionalities. Here we report a nanoplasmonic study of vdW heterostructures that were produced by depositing ordered molecular layers of pentacene on top of graphene. We find through nanoinfrared (IR) imaging that surface plasmons formed due to the collective oscillations of Dirac Fermions in graphene are highly sensitive to the adjacent pentacene layers. In particular, the plasmon wavelength declines systematically but nonlinearly with increasing pentacene thickness. Further analysis and density functional theory (DFT) calculations indicate that the observed peculiar thickness dependence is mainly due to the tunneling-type electron transfer from pentacene to graphene. Our work unveils a new method for tailoring graphene plasmons and deepens our understanding of the intriguing nano-optical phenomena due to interlayer couplings in novel vdW heterostructures.

Abstract
Objective: To evaluate the influence of antiretroviral prophylaxis on the growth and development of HIV-exposed uninfected infants in Guangzhou. Methods: Data were from the national information system for prevention of mother-to-child transmission of HIV infection, syphilis and hepatitis B. After excluding death and perinatal HIV infection cases, 564 HIV-exposed uninfected infants were included. The infants were divided into three groups, nevirapine (NVP) group, zidovudine (AZT) group and untreated group. The influences of antiretroviral prophylaxis on the body weight and height of the HIV-exposed uninfected infants were analyzed by using generalized estimating equations. Results: The HIV-exposed uninfected infants at 1-month old had lower Z scores of body weight-for-age and body height-for-age than the World Health Organization's reference standard. The prevalence of wasting in AZT group (17.5%) was higher than that in NVP group (6.2%) for 1-month old infants. Taking NVP or AZT was a protective factor for Z score of body length-for-age (P<0.05). Intrauterine exposure to triple antiviral drugs was a risk factor for the Z scores of body weight-for-age and body length-for-age (P<0.05). Conclusion: The physical growth and development of HIV-exposed uninfected infants at 1-month old was not well, and HIV-exposed uninfected infants who taking AZT had a higher incidence of wasting. Attention should be paid to these infants.

Abstract
Objective: To investigate the association of both maternal pre-pregnancy body mass index (BMI) and gestational weight gain (GWG) with childhood overweight and adiposity in preschool children. Methods: A total of 4 303 preschool children aged 3-5 years were enrolled in our study during June and November 2016 in Guangzhou. Children defined as overweight and obesity were according to the criteria of WHO while weight status during maternal pre-pregnancy was using the China Adult Reference. Gestational weight gain was defined according to the Institute of Medicine guidelines. Results: After adjusting the possible confounding factors, results from the logistic regression analysis showed that both maternal pre-pregnancy overweight and obesity would increase the risk for both childhood overweight and obesity (OR=1.820, 95%CI: 1.368-2.422). The analysis of covariance results also showed that both maternal overweight and obesity before pregnancy and excessive maternal weight gain during pregnancy increased the BMI Z-score in children. Maternal GWG over the recommended level were associated with both the childhood overweight and obesity (OR=1.296, 95%CI: 1.007-1.667). Joint associations of pre-pregnancy BMI and inappropriate GWG were also noticed in the study. Stratified analysis was conducted in three groups according to the pre-pregnancy BMI of the mothers. Result showed that there was no statistical difference in the risks of either overweight or obesity in children (P>0.05). However, when compared to mothers with adequate pre-pregnancy higher BMI and adequate GWG, under the combination of high pre-pregnancy BMI and excessive GWG, their adverse effects on childhood overweight and obesity were much higher (OR=1.574, 95%CI: 1.029-2.409). Conclusions: Both high pre-pregnancy BMI and inappropriate GWG were associated with greater BMI of their offspring. Pregnant women should follow the appropriate weight gain program and help their children to prevent from becoming obese.

Abstract
Gastric cancer (GC) is the fourth leading cause of gynecological malignancies worldwide. 5-fluorouracil (5-FU)-mediated chemotherapy is the adjuvant treatment for patients with GC following surgical resection. Many studies have indicated the cancer-type specific roles of forkhead box protein A1 (FOXA1) and keratin 7 (KRT7) in human malignancies. However, the potential mechanism underlying the involvement of FOXA1 and KRT7 in the pathogenesis and chemoresistance of GC are still not entirely clear. In our study, gain- and loss-of-function experiments proved that FOXA1 promoted cell proliferation, migration and invasion in AGS and SGC-7901 cells. Consequently, KRT7 was identified to be transcriptional activated by FOXA1 using Dual luciferase reporter assay. Our results also indicated that FOXA1 exerted its functions in enhancing viability and invasion of AGS and SGC-7901 cells through activating KRT7. Finally, interference of FOXA1 or KRT7 increased the chemosensitivity of AGS and SGC-7901 cells to 5-fluorouracil (5-Fu) treatment by suppressing cell proliferation. In conclusion, these data indicate that FOXA1 promoted proliferation, migration, invasion, and decreased chemosensitivity of GC cells to 5-Fu treatment through transcriptional activator KRT7. The present study provides a novel therapeutic strategy for the enhancement of efficacy in GC treatment and provides important insights into the molecular mechanism underlying 5-FU-mediated chemoresistance.

Abstract
BACKGROUND Patients with chronic liver diseases (CLDs) often suffer from lipidosis or siderosis. Proton density fat fraction (PDFF) and R2* can be used as quantitative parameters to assess the fat/iron content of the liver. The aim of this study was to evaluate the influence of liver fibrosis and inflammation on the 3D Multi-echo Dixon (3D ME Dixon) parameters (MRI-PDFF and R2*) in patients with CLDs and to determine the feasibility of 3D ME Dixon technique for the simultaneous assessment of liver steatosis and iron overload using histopathologic findings as the reference standard. METHODS Ninety-nine consecutive patients with CLDs underwent T1-independent, T2*-corrected 3D ME Dixon sequence with reconstruction using multipeak spectral modeling on a 3T MR scanner. Liver specimen was reviewed in all cases, grading liver steatosis, siderosis, fibrosis, and inflammation. Spearman correlation analysis was performed to determine the relationship between 3D ME Dixon parameters (MRI-PDFF and R2*) and histopathological and biochemical features [liver steatosis, iron overload, liver fibrosis, inflammation, alanine aminotransferase (ALT), aspartate aminotransferase (AST), total bilirubin (TBIL)]. Multiple regression analysis was applied to identify variables associated with 3D ME Dixon parameters. Receiver operating characteristic (ROC) analysis was performed to determine the diagnostic performance of these parameters to differentiate liver steatosis or iron overload. RESULTS In multivariate analysis, only liver steatosis independently influenced PDFF values (R2=0.803, P<0.001), liver iron overload and fibrosis influenced R2* values (R2=0.647, P<0.001). The Spearman analyses showed that R2* values were moderately correlated with fibrosis stages (r=0.542, P<0.001) in the subgroup with the absence of iron overload. The area under the ROC curve of PDFF was 0.989 for the diagnosis of steatosis grade 1 or greater, and 0.986 for steatosis grade 2 or greater. The area under the ROC curve of R2* was 0.815 for identifying iron overload grade 1 or greater, and 0.876 for iron overload grade 2 or greater. CONCLUSIONS 3D Multi-Echo Dixon can be used to simultaneously evaluate liver steatosis and iron overload in patients with CLDs, especially for quantification of liver steatosis. However, liver R2* value may be affected by the liver fibrosis in the setting of CLDs with absence of iron overload.

Abstract
LD chips, combined with phosphor converters, are considered as optimum candidates for high brightness lighting. In this work, Al2O3-YAG:Ce composite ceramics were prepared as the phosphor converters. The sintering temperature and the sintering additives were optimized to obtain the highest quantum efficiency. The effect of the molar ratio of Al2O3 to YAG:Ce on the performance of the ceramics that were excited by the LD chips was studied. The results show that the light extraction efficiency from the ceramic surfaces increases with the increasing molar ratio of Al2O3 to YAG:Ce. Moreover, the improved thermal conductivity caused the ceramics with higher molar ratio of Al2O3 to YAG:Ce show alleviative luminescence saturation and improved reliability.

OBJECTIVES This study aims to investigate the prevalence of vitamin D deficiency in Chinese centenarians and to identify the factors associated with vitamin D deficiency. DESIGN Cross-sectional population-based study. SETTING Hainan province in the south of China. PARTICIPANTS 943 subjects aged 100 years old and older. METHODS Details on sociodemographics and lifestyle characteristics were collected using a structured questionnaire. Anthropometrics and blood samples were obtained. Vitamin D deficiency was defined as serum 25-hydroxyvitamin D concentration < 20ng/mL (50nmol/L). RESULTS The overall prevalence of vitamin D deficiency among these 943 centenarians was 39.9% (376 subjects) and the mean serum vitamin D concentrations were 22.7±9.5 (ng/mL). Female centenarians had higher prevalence of vitamin D deficiency than male (44.0% vs. 21.7%, P <0.001). Multivariate logistic regression analyses showed that being female, urban residency, lower body mass index, higher serum parathyroid hormone levels, no fish consumption, and less sun exposure time were all significant and independent determinants of vitamin D deficiency. No significant associations of vitamin D deficiency with ethnic, education, geographic location, tea drinking, alcohol use, or smoking were found in this study. CONCLUSION Vitamin D deficiency was common in Chinese centenarians, especially in women. Given that vitamin D deficiency is linked to numerous adverse health outcomes, dietary, outdoor activities and other intervention measures are needed to correct vitamin D deficiency in this population.

Abstract
INTRODUCTION It is urgent to find an effective method to diagnose and prognose early hepatocellular carcinoma (HCC). The purpose of this study was to investigate the correlation between HCC histological degree and water percentage (WP) obtained from magnetic resonance imaging 3D-VIBE multiecho Dixon, and to evaluate the feasibility of WP in the postoperative prediction of early HCC recurrence. METHODS AND MATERIALS From June 2016 to July 2017, 76 patients with diagnostic HCC all underwent 3D-VIBE Multiecho Dixon and ultrahigh b value diffusion-weighted imaging (DWI) examination. Freehand regions of interests were placed to measure the WP and apparent diffusion coefficient (ADC) value. The Edmondson-Steiner (E-S) grades proved by histopathological results were acquired from all patients. Comparisons between mean WP and ADC with E-S grades I-IV were performed using Kruskal-Wallis test and one-way ANOVA. Least Significant Difference t-test (LSD-t test) was applied to compare particular pairs of mean ADC value between every two E-S groups. Correlations between WP, ADC, and E-S grades were assessed by Spearman's rank correlation test. The Mann-Whitney U test was utilized to compare the difference of mean WP between recurrence and nonrecurrence group. The receiver operating characteristic (ROC) curves were calculated to estimate the diagnostic effect of 3D-VIBE Multiecho Dixon and ultrahigh b value DWI to HCC. Kaplan-Meier method was used to evaluate the recurrence free survival (RFS) after surgical resection. RESULTS Mean WP values among groups E-S I to IV were 91.8%, 95.2%, 96.4%, and 97.7%, respectively. A positive correlation was exhibited between the WP and histopathological E-S grades (r = 0.480, p < 0.01). The ADC values based on E-S grades were 0.93, 0.82, 0.74, and 0.62 × 10-3 mm2/s, respectively. Significant differences were found between every two E-S groups (p < 0.01), and a negative correlation between ADC and E-S grades (r = -0.784, p = 0.000) was observed. Mean value of WP was 97.2% in recurrence group and 94.6% in nonrecurrence group (p < 0.01). The optimal cutoff value was 95.7%. The maximal area under the ROC curve was 0.747 ± 0.06 for WP, 0.631 ± 0.07 for ADC, and 0.753 ± 0.06 for the combination of WP and ADC. Mean RFS was 18.1 months in the lower WP and 10.7 months in higher WP group (p < 0.01). CONCLUSIONS WP can be used as a potential biomarker for the diagnosis and prognosis of HCC. A lower value of WP may imply a better outcome in patients after surgical resection.

Abstract
BACKGROUND Several studies have shown that diabetes confers a higher relative risk of vascular mortality among women than among men, but whether this increased relative risk in women exists across age groups and within defined levels of other risk factors is uncertain. We aimed to determine whether differences in established risk factors, such as blood pressure, BMI, smoking, and cholesterol, explain the higher relative risks of vascular mortality among women than among men. METHODS In our meta-analysis, we obtained individual participant-level data from studies included in the Prospective Studies Collaboration and the Asia Pacific Cohort Studies Collaboration that had obtained baseline information on age, sex, diabetes, total cholesterol, blood pressure, tobacco use, height, and weight. Data on causes of death were obtained from medical death certificates. We used Cox regression models to assess the relevance of diabetes (any type) to occlusive vascular mortality (ischaemic heart disease, ischaemic stroke, or other atherosclerotic deaths) by age, sex, and other major vascular risk factors, and to assess whether the associations of blood pressure, total cholesterol, and body-mass index (BMI) to occlusive vascular mortality are modified by diabetes. RESULTS Individual participant-level data were analysed from 980 793 adults. During 9·8 million person-years of follow-up, among participants aged between 35 and 89 years, 19 686 (25·6%) of 76 965 deaths were attributed to occlusive vascular disease. After controlling for major vascular risk factors, diabetes roughly doubled occlusive vascular mortality risk among men (death rate ratio [RR] 2·10, 95% CI 1·97-2·24) and tripled risk among women (3·00, 2·71-3·33; χ2 test for heterogeneity p<0·0001). For both sexes combined, the occlusive vascular death RRs were higher in younger individuals (aged 35-59 years: 2·60, 2·30-2·94) than in older individuals (aged 70-89 years: 2·01, 1·85-2·19; p=0·0001 for trend across age groups), and, across age groups, the death RRs were higher among women than among men. Therefore, women aged 35-59 years had the highest death RR across all age and sex groups (5·55, 4·15-7·44). However, since underlying confounder-adjusted occlusive vascular mortality rates at any age were higher in men than in women, the adjusted absolute excess occlusive vascular mortality associated with diabetes was similar for men and women. At ages 35-59 years, the excess absolute risk was 0·05% (95% CI 0·03-0·07) per year in women compared with 0·08% (0·05-0·10) per year in men; the corresponding excess at ages 70-89 years was 1·08% (0·84-1·32) per year in women and 0·91% (0·77-1·05) per year in men. Total cholesterol, blood pressure, and BMI each showed continuous log-linear associations with occlusive vascular mortality that were similar among individuals with and without diabetes across both sexes. INTERPRETATION Independent of other major vascular risk factors, diabetes substantially increased vascular risk in both men and women. Lifestyle changes to reduce smoking and obesity and use of cost-effective drugs that target major vascular risks (eg, statins and antihypertensive drugs) are important in both men and women with diabetes, but might not reduce the relative excess risk of occlusive vascular disease in women with diabetes, which remains unexplained.

Abstract
BACKGROUND The spread of carbapenem-resistant Klebsiella pneumoniae (CR-KPN) is a major concern, but data on CR-KPN infection/colonization in paediatric populations are limited. AIM To analyse epidemiologic and clinical characteristics, and therapeutic options for CR-KPN infections in neonates in China. METHODS A retrospective study was performed at the Children's Hospital of Fudan University, including 88 neonates with CR-KPN admitted between November 2015 and October 2016. Forty-seven CR-KPN isolates were chosen at random for further study, including antimicrobial susceptibility testing, potential β-lactamase screening and homology analysis. FINDINGS In total, 44.3% (39/88) of the neonates with CR-KPN were infected, and 71.8% (28/39) were nosocomial infections. Of these, pneumonia and urinary tract infection accounted for 50.0% (14/28) and 42.9% (12/28), respectively. All infected patients were cured or improved with fosfomycin and/or carbapenem-containing combination therapy, except one case in whom treatment was withdrawn. All 47 cases of CR-KPN were resistant to ertapenem and 95.7% were resistant to imipenem/meropenem. Overall, 87.2% (41/47) were positive for blaNDM-1, and belonged to 11 pulsed-field gel electrophoresis types; 53.7% (22/41) were designated as ST278 and 17.1% (7/41) were designated as ST2735 by multi-locus sequence typing. CONCLUSIONS Most of the CR-KPN isolated from neonates produced New Delhi metallo-beta-lactamase-1 and were highly homologous. Fosfomycin-containing regimens and meropenem-/panipenem-containing combination therapy were efficient for CR-KPN infection in neonates.
