Abstract
Objective: To investigate the effects of sirolimus combined with anti-CD20 monoclonal antibody desensitization on the prognosis of patients with haploidentical stem cell transplantation (haplo-SCT). Methods: Fifteen consecutive patients who received haplo-SCT and pre-transplant donor specific anti-human leukocyte antigen (HLA) antibody (DSA) positive [mean fluorescence intensity (MFI)≥2 000] in the Institute of Hematological Diseases from November 2021 to March 2023 were retrospectively recruited into the desensitized group. There were 4 males and 11 females, with a median age [M(Q1, Q3)] of 48 (37, 59) years. All patients were desensitized with sirolimus combined with anti-CD20 monoclonal antibody. The non-desensitized group included 29 patients with haplo-SCT who had not received desensitization treatment from August 2012 to June 2016. There were 12 males and 17 females with a median age of 42 (26, 50) years. Up to October 1, 2023, the median follow-up time was 13 (9, 18) months in the study group and 23 (14, 29) months in the control group. The changes of MFI before and after desensitization treatment and the prognosis of patients in the desensitized group were compared, including the incidence of primary implantation failure (pGF), neutrophil implantation time, platelet implantation time, grade Ⅱ-Ⅳ acute graft-versus-host disease (GVHD) and chronic GVHD incidence, non-recurrence related mortality, event-free survival rate, disease-free survival rate and overall survival rate. The survival curve was drawn by Kaplan-Meier method, and the survival rate between groups was compared with Log-rank test. Results: After desensitization treatment, the level of DSA MFI in the desensitized group decreased from 8 879 (7 544, 11 495) to 3 781 (1 638, 4 165) after desensitization treatment (P<0.01). All of the patients achieved hematopoietic recovery, and the median time for neutrophil and platelet engraftment were 14 (11, 15) and 20 (18, 25) days, respectively. The incidence of pGF in the desensitized group was 0, which was lower than that in the non-desensitized group (34.5%, 10/29) (P=0.011). The expected 1-year disease-free survival rate and overall survival rate in the desensitized group were 100% (15/15) and 100% (15/15) respectively, while those in the non-desensitized group were 75.9% (22/29) and 75.9% (22/29) respectively, the difference was not statistically significant (both P>0.05). The one-year event-free survival rate in the desensitized group was expected to be 100% (15/15), which was higher than that in the non-desensitized group (51.3%, 15/29) (P=0.002). Conclusion: Sirolimus combined with anti-CD20 monoclonal antibody desensitization therapy can reduce the DSA level of haplo-SCT recipients, promote hematopoietic engraftment after transplantation, and avoid the occurrence of pGF after transplantation.

Abstract
Objective: This study aimed to observe the dynamic changes of NUP98::NSD1 expression before and after allogeneic hematopoietic stem cell transplantation (allo-HSCT) . Moreover, the clinical value of measurable residual disease (MRD) was analyzed. Methods: Sixteen AML patients who were diagnosed with the NUP98::NSD1 fusion gene and received allo-HSCT at Peking University People's Hospital were included. The NUP98::NSD1 fusion gene and leukemia-associated immunophenotype (LAIP) were monitored before and after transplantation to evaluate their MRD status. Results: The median follow-up time for all patients was 526 days (139-1136 days) , with four patients (25.0%) experiencing hematological recurrence at a median of 474 days (283-607 days) after transplantation. Three patients (18.8%) died, two of whom (12.5%) died of leukemia recurrence. The median expression level of NUP98::NSD1 in newly diagnosed patients with complete data was 78.5% (18.9%-184.4%) at the time of initial diagnosis. The recurrence rate was higher in NUP98::NSD1-positive patients after transplantation, with 44.4% of patients experiencing recurrence, whereas no recurrence occurred in NUP98::NSD1-negative patients after transplantation. The area under the receiver operating characteristic curve predicted by the NUP98::NSD1 level after transplantation was 1.000 (95% confidence interval: 1.000-1.000, P=0.003) . Among the four patients with recurrence, NUP98::NSD1 was more sensitive than flow cytometry residual (FCM) and Wilms' tumor gene 1 (WT1) . Conclusions: The NUP98::NSD1 fusion gene can be used to evaluate the MRD status of allo-HSCT. NUP98::NSD1-positive patients after transplantation have a high relapse rate and poor prognosis. NUP98::NSD1 was more sensitive than FCM and WT1 in predicting posttransplant relapse.

Abstract
Changes in daylight amount (photoperiod) drive pronounced alterations in physiology and behaviour1,2. Adaptive responses to seasonal photoperiods are vital to all organisms - dysregulation is associated with disease, from affective disorders3 to metabolic syndromes4. Circadian rhythm circuitry has been implicated5,6 yet little is known about the precise neural and cellular substrates that underlie phase synchronization to photoperiod change. Here we present a previously unknown brain circuit and novel system of axon branch-specific and reversible neurotransmitter deployment that together prove critical for behavioural and sleep adaptation to photoperiod change. We found that the recently defined neuron type called mrEn1-Pet17 located in the mouse brainstem Median Raphe Nucleus (MRN) segregates serotonin versus VGLUT3 (here proxy for the neurotransmitter glutamate) to different axonal branches innervating specific brain regions involved in circadian rhythm and sleep/wake timing8,9. We found that whether measured during the light or dark phase of the day this branch-specific neurotransmitter deployment in mrEn1-Pet1 neurons was indistinguishable; however, it strikingly reorganizes on photoperiod change. Specifically, axonal boutons but not cell soma show a shift in neurochemical phenotype upon change away from equinox light/dark conditions that reverses upon return to equinox. When we genetically disabled the deployment of VGLUT3 in mrEn1-Pet1 neurons, we found that sleep/wake periods and voluntary activity failed to synchronize to the new photoperiod or was significantly delayed. Combining intersectional rabies virus tracing and projection-specific neuronal silencing in vivo, we delineated a Preoptic Area-to-mrEn1Pet1 connection responsible for decoding the photoperiodic inputs, driving the neurochemical shift and promoting behavioural synchronization. Our results reveal a previously unrecognized brain circuit along with a novel form of periodic, branch-specific neurotransmitter deployment that together regulate organismal adaptation to photoperiod changes.

Abstract
BACKGROUND Currently there is limited information to guide health professionals regarding the optimal time frame to initiate safe and effective oral feedings to preterm infants. The study aims to revise and validate a streamlined version of the Traditional Chinese-Preterm Oral Feeding Readiness Assessment Scale, the TC-POFRAS®, and evaluate its construct validity in the clinical decisions regarding feeding readiness of preterm infants. METHODS Eighty-one clinically stable preterm infants were assessed using the TC-POFRAS for oral feeding readiness. Item-total correlation analysis was used to check if any item was inconsistent with the averaged TC-POFRAS scores. Cronbach's α coefficient was used to evaluate the inter-item consistency. Exploratory factor analysis was used to determine the coherence of variables to reorganize assessment domains. The revised version of TC-POFRAS (TC-POFRAS®) was developed and a new cut-off score based on discriminant accuracy was established. RESULTS Based on the results from statistical analysis, five items ("lips posture," "tongue posture," "biting reflex," "gag reflex," and "tongue cupping") were deleted from the original TC-POFRAS to form the TC-POFRAS®. The TC-POFRAS®'s global accuracy was 92.1%. The cut-off value of 19 was the one that presented the most optimization of sensitivity based on specificity. The TC-POFRAS® was reconstructed into corrected gestational age and five behavioral domains. CONCLUSIONS The TC-POFRAS® is considered a valid, safe, and accurate objective instrument to assist health professionals to initiate oral feeding of preterm infants.

Abstract
Objective: To investigate the dynamic change and clinical impact of DEK-NUP214 fusion gene in patients with acute myeloid leukemia (AML) receiving allogeneic hematopoietic stem cell transplantation (allo-HSCT). Methods: Real-time quantitative polymerase chain reaction (RQ-PCR) and multicolor flow cytometry (FCM) were used to detect DEK-NUP214 gene expression and leukemia-associated immunophenotype (LAIP) in 15 newly diagnosed patients with positive DEK-NUP214 and receiving allo-HSCT from September 2012 to September 2017 at Peking University People's Hospital. The clinical outcome was analyzed using Kaplan-Meier survival curves. The impact of DEK-NUP214 expression was analyzed by log-rank test. Results: The subjects were followed-up with a median period of 657 (62-2 212) days. The median DEK-NUP214 expression level at diagnosis was 488% (274%-1 692%). Thirteen patients achieved complete remission before allo-HSCT. Thirteen patients had a residual DEK-NUP214 expression of 0.38% (0.029%-738.9%) before allo-HSCT. After allo-HSCT, DEK-NUP214 expression in 9/13 patients remained positive, which dropped by around 500 folds (5.7-5 663.0 folds) within a month post-transplant. Five patients died and 2 patients relapsed. The 3-year cumulative incidence of relapse in patients with positive DEK-NUP214 before transplant was 17.5%±11.3% and the 3-year overall survival was 60.5%±13.8%. After allo-HSCT, DEK-NUP214-negative patients had a better outcome. Conclusion: Quantitative monitor of DEK-NUP214 fusion gene could be a sensitive indicator of MRD status after allo-HSCT.

Abstract
BACKGROUND The study aimed to assess the correlation between long-term survival and treatment in very young women with breast cancer. METHODS Data on women with breast cancer were retrieved from the Taiwan Cancer Registry between 2004 and 2014. Patients who did not undergo surgery or who had stage 0 or IV disease were excluded. Survival analysis was conducted. The participants were divided into very young (20-29.9 years), young (30-39.9 years), and adult (40-50.0 years) groups. RESULTS Among 104 115 women, 24 474 (572 very young, 5565 young, and 18 337 adult) were eligible for the study. Median follow-up was 79.5 (range 24-158) months. The mortality rates in the very young, young, and adult groups were 12.9, 10.0, and 8.2 per cent respectively (P < 0.001). Very young patients had higher histological grade, unfavourable subtype, higher TNM stage, and received more breast-conserving surgery (BCS). Kaplan-Meier survival analysis showed that very young patients had the poorest long-term survival. Very young patients with stage II disease had the worst prognosis. In the multivariable regression model, radiotherapy was associated with decreased local recurrence but not with improved overall, cancer-specific, or disease-free survival for stage II disease in the very young group. Surgery type and chemotherapy were not associated with significant improvement in overall survival. CONCLUSION Very young patients with stage II disease had poor long-term outcomes. BCS had no detrimental effects on long-term outcomes.

Abstract
Objective: To investigate the incidences and risk factors of poor hematopoietic reconstitution (PHR) in patients with hematological diseases who underwent haploidentical allograft and were treated with rituximab for desensitization. Methods: Eight-three donor specific anti-HLA antibody (DSA, 2000 ≤MFI<10 000) positive patients who underwent haploidentical allograft were prospectively enrolled. Rituximab (375 mg/m2) was used for desensitization day-3 of conditioning regimen. Incidence and factors associated with PHR, including primary poor graft function and prolonged thrombocytopenia, were investigated. Results: There were 22 males and 61 females with a median age of 39(range: 1-65) years. Kaplan-Meier analysis showed that the 100 day cumulative incidences of neutrophil and platelet engraftment were 93.0% and 90.7%, respectively. The incidences of PHR were 14.7%. The 3-year relapse rate, non-relapse mortality (NRM) rate, event-free survival (EFS), leukemia-free survival (DFS) and overall survival (OS) were 6.5%, 15.1%, 70.8%, 79.4% and 79.4%, respectively. Patients with DSA MFI<5 000 (group A, n=46) experienced lower PHR (4.4% vs. 27.5%, P=0.003), and higher 3-year EFS (79.5% vs. 59.8%, P=0.020) compared to those with DSA MFI≥5 000 (group B, n=37). Multivariate analysis showed that DSA MFI≥5 000 was correlated with PHR (HR=6.101, P=0.021). PHR was associated with higher NRM (HR=4.110, P=0.026), lower DFS (HR=3.656, P=0.019) and OS (HR=3.656, P=0.019). Conclusion: Our data suggest that high pre-transplant DSA level is a risk factor for PHR in patients with hematological diseases receiving haploidentical allograft and rituximab for desensitization.

Abstract
目的 探讨多参数流式细胞术(MFC)与实时定量聚合酶链反应技术(RQ-PCR)两种方法检测费城染色体阳性(Ph+)急性B淋巴细胞白血病(B-ALL)患者异基因造血干细胞移植(allo-HSCT)前微小残留病(MRD)的预后意义。 方法 回顾性分析2014年7月至2018年2月在北京大学血液病研究所接受allo-HSCT的280例Ph+ B-ALL患者,同时用MFC和RQ-PCR法(检测BCR-ABL融合基因表达)检测移植前MRD。 结果 RQ-PCR与MFC检测MRD具有相关性(rs=0.435,P<0.001)。MFC、RQ-PCR法检测移植前MRD的阳性率分别为25.7%(72/280)、60.7%(170/280)。移植前MFC-MRD阳性组患者移植后白血病3年累积复发率(CIR)明显高于MFC-MRD阴性组(23.6%对8.6%,P<0.001)。RQ-PCR检测BCR/ABL融合基因阳性组(RQ-PCR MRD阳性组)的3年CIR、非复发死亡(NRM)、无白血病生存(LFS)、总生存(OS)与BCR/ABL融合基因阴性组(RQ-PCR MRD阴性组)相比差异均无统计学意义(P>0.05)。移植前RQ-PCR MRD≥1%组比<1%组具有更高的3年CIR(23.1%对11.4%,P=0.032)、更低的LFS率(53.8%对74.4%,P=0.015)与OS率(57.7%对79.1%,P=0.009)。多因素分析显示,移植前MFC-MRD阳性是影响移植后CIR的危险因素(HR=2.488,95%CI1.216~5.088,P=0.013),移植前RQ-PCR MRD≥1%是影响LFS(HR=2.272,95%CI 1.225~4.215,P<0.001)、OS(HR=2.472,95% CI 1.289~4.739,P=0.006)的危险因素。MFC检测MRD预测复发的敏感性、特异性、阳性预测值(PPV)、阴性预测值(NPV)分别为48.50%、77.56%、23.62%、87.16%。以RQ-PCR MRD≥1%预测复发的敏感性、特异性、PPV、NPV分别为23.00%、88.59%、17.15%、91.84%。移植前MFC-MRD阳性或RQ-PCR MRD≥1%二者任一成立为指标预测移植后复发的敏感性、特异性、PPV、NPV分别为54.29%、73.88%、45.70%、91.87%。 结论 MFC和RQ-PCR法检测移植前MRD水平均可预测Ph+ B-ALL患者移植预后。移植前MFC-MRD阳性是移植后复发的危险因素。联合使用两种方法(移植前MFC-MRD阳性状态或RQ-PCR MRD≥1%成立)可提高预测移植后复发的敏感性、阳性预测值与阴性预测值,有助于更好筛选出高危患者。

Abstract
Objective: To evaluate the efficacy of consolidation chemotherapy combined with allogeneic natural killer (NK) cell infusion in the treatment of low or intermediate-risk (LIR) acute myeloid leukemia (AML) . Methods: A cohort of 23 LIR AML patients at hematologic complete remission (CR) received NK cell transfusion combined with consolidation chemotherapy after 3 consolidation courses from January 2014 to June 2019 were reviewed. Control group cases were concurrent patients from Department of Hematology, and their gender, age, diagnosis, risk stratification of prognosis, CR and the number of courses of consolidate chemotherapy before NK cell transfusion were matched with LIR AML patients. Results: A total of 45 times of NK cells were injected into 23 LIR AML patients during 4 to 7 courses of chemotherapy. The median NK cell infusion quantity was 7.5 (6.6-8.6) ×10(9)/L, and the median survival rate of NK cells was 95.4% (93.9%-96.9%) . Among them, the median CD3(-)CD56(+) cell number was 5.0 (1.4-6.4) ×10(9)/L, accounting for 76.8% (30.8%-82.9%) ; The number of CD3(+) CD56(+) cells was 0.55 (0.24-1.74) ×10(9)/L, accounting for 8.8% (4.9%-20.9%) . Before NK cell infusion, the number of patients with positive MRD in the treatment and control groups were 9/23 (39.1%) and 19/46 (41.3%) (χ(2)=0.030, P=0.862) respectively. After NK infusion, There was no significant difference in terms of MRD that went from negative to positive between the treatment and the control groups (14.3% vs 22.2%, χ(2)=0.037, P=0.847) . In the treatment group, 66.7% (6/9) of the MRD were converted from positive to negative, which was significantly higher than that in the control group (10.5%, 2/19) (χ(2)=6.811, P=0.009) . Morphological recurrence occurred in 1 case of MRD negative in the treatment group and 2 cases of MRD positive in the control group. By the end of follow-up, the median follow-up was 35 (10-59) months, the number of patients with morphological recurrence in the treatment group was 30.4% (7/23) , which was significantly lower than that in the control group (50.2%, 24/46) (χ(2)=2.929, P=0.087) , although there was no statistically significant difference between the two groups. There was no significant difference on MRD-negative between the treatment and the control groups (43.5% vs 43.5%, χ(2)=1.045, P=0.307) . The 3-year leukemia-free survival was better in the treatment group [ (65.1±11.1) %] than that in the control group [ (50.0±7.4) %] (P=0.047) . The 3-year overall survival in the treatment and control groups were (78.1±10.2) % and (65.8±8.0) % (P=0.212) , respectively. Conclusion: The consolidation of chemotherapy combined with allogeneic NK cell infusion contributed to the further remission of patients with LMR AML and the reduction of long-term recurrence.

Abstract
Length and mass data for 1260 (536 females, 683 males, 41 sex unknown) striped marlin Kajikia audax were collected at the fish markets of Tungkang, Singkang and Nanfangao from July 2004 to September 2010. Of these samples, 534 gonads (236 females and 298 males) ranging from 95 to 206 cm in eye-to-fork length (LEF ) and 8 to 88 kg in round mass (MR ), were collected. Chi-square tests indicated sex ratios were homogeneous among months in 2004 and 2006-2008, but not in 2005, 2009 and 2010; and there were significant differences in sex ratio by size. The overall sex ratio (RS ) differed significantly from the expected 0·5. Kajikia audax are sexually dimorphic and the proportions of females increased with size between 140 and 210 cm LEF . Reproductive activity was assessed using a gonado-somatic index (IG ), external appearance of the gonads and histological examination and results indicated that the spawning season occurred from April to August with a peak in June to July. Based on histological observations and the distribution of oocyte diameters, K. audax are multiple spawners and their oocytes develop asynchronously. The estimated length-at-50% maturity (LEF50 ) was c. 181 cm (c. 4·8 years of age) for females. The proportion of reproductively active females in the spawning season with ovaries containing postovulatory follicles (0·27) indicated that they spawned every 3·7 days on average. The hydrated oocyte method estimated mean ± S.D. batch fecundity (FB ) to be 4·4 ± 2·02 million eggs; average relative fecundity was 53·6 ± 13·9 oocytes g-1 MR ; and the average annual fecundity was 181·3 ± 48·3 million eggs. The parameters estimated in this study are key information for stock assessments of K. audax in the north-western and central Pacific and will contribute to the conservation, management and sustainable yield of this species.

Abstract
Current anti-epidermal growth factor receptor (EGFR) therapy for oral cancer does not provide satisfactory efficacy due to drug resistance or reduced EGFR level. As an alternative candidate target for therapy, here we identified an oncogene, ROS1, as an important driver for oral squamous cell carcinoma (OSCC) metastasis. Among tumors from 188 oral cancer patients, upregulated ROS1 expression strongly correlated with metastasis to lung and lymph nodes. Mechanistic studies uncover that the activated ROS1 results from highly expressed ROS1 gene instead of gene rearrangement, a phenomenon distinct from other cancers. Our data further reveal a novel mechanism that reduced histone methyltransferase EZH2 leads to a lower trimethylation of histone H3 lysine 27 suppressive modification, relaxes chromatin, and promotes the accessibility of the transcription factor STAT1 to the enhancer and the intron regions of ROS1 target genes, CXCL1 and GLI1, for upregulating their expressions. Down-regulation of ROS1 in highly invasive OSCC cells, nevertheless, reduces cell proliferation and inhibits metastasis to lung in the tail-vein injection and the oral cavity xenograft models. Our findings highlight ROS1 as a candidate biomarker and therapeutic target for OSCC. Finally, we demonstrate that co-targeting of ROS1 and EGFR could potentially offer an effective oral cancer therapy.

Abstract
OBJECTIVES The study aimed to determine the long-term Staphylococcus aureus colonization patterns and strain relatedness, and the association between maternal and infant colonization in infancy. METHODS A birth cohort study was conducted from January 2012 to November 2014. Nasopharyngeal swabs for S. aureus detection were collected from infants at the age of 1, 2, 4, 6 and 12 months and from mothers when their children were 1-month-old. RESULTS In total, 254 samples were collected at each planned visit during the first 12-month study. The prevalence of S. aureus colonization decreased in the first year of life, ranging from 61.0% (155/254) at the age of 1 month to 12.2% (31/254) at 12 months. Persistent colonization, defined as a positive culture on four or five occasions, was detected in only 13.8% (35/254) of carriers. Most of the persistent carriers were colonized with methicillin-resistant S. aureus (MRSA) only, and among persistent MRSA carriers, 61.1% (11/18) had indistinguishable genotypes. Of the mothers with MRSA colonization, 77.1% (27/35) had infants who were concomitantly colonized at the age of 1 month; 70.4% (19/27) of the infant-mother paired isolates belonged to indistinguishable or related subtypes, which suggests that surrounding carriers, probably their mothers, may be the possible source for MRSA acquisition in early infancy. CONCLUSIONS Staphylococcus aureus colonization including MRSA was commonly observed in our cohort. Strains of persistent MRSA among infant-mother pairs were usually of indistinguishable genotypes. Therefore, horizontal spread within households is possibly an important factor related to infant MRSA colonization.

Abstract
BACKGROUND This study aimed to assess long-term survival after liver resection for huge hepatocellular carcinoma (HCC). METHODS Patients with stage I-III HCC who underwent hepatectomy from 2002 to 2010 were identified retrospectively from prospective national databases and followed until December 2012. Patients were assigned into four groups according to tumour size: less than 3·0 cm (small), 3·0-4·9 cm (medium), 5·0-10·0 cm (large) and over 10·0 cm (huge). The primary endpoint was overall survival. The Kaplan-Meier method and Cox proportional hazards model were used for survival analysis. RESULTS A total of 11 079 patients with HCC (mean(s.d.) age 59·7 (12·0) years) were eligible for this study. Median follow-up was 72·5 months. Patients with huge HCC had the worst prognosis; overall survival rates for patients with small, medium, large and huge HCC were 72·0, 62·1, 50·8 and 35·0 per cent respectively at 5 years, and 52·6, 41·8, 35·8 and less than 20·0 per cent at 10 years (P < 0·001). Multivariable analysis showed that tumour size affected long-term survival (hazard ratio (HR) 1·31, 1·55 and 2·38 for medium, large and huge HCC respectively versus small HCC). Prognostic factors for huge HCC were surgical margin larger than 0·2 cm (HR 0·70; P = 0·025), poor differentiation (HR 1·34; P = 0·004), multiple tumours (HR 1·64; P < 0·001), vascular invasion (HR 1·52; P = 0·008), cirrhosis (HR 1·37; P = 0·013) and the use of nucleoside analogues (HR 0·69; P = 0·004). CONCLUSION Huge HCCs have a worse prognosis than smaller HCCs after liver resection. A wide resection margin and antiviral therapy with nucleoside analogues may be associated with favourable long-term survival.

Abstract
Background Allogeneic hematopoietic stem cell transplantation (allo-HSCT) has been established as an effective treatment for patients with hematological malignancies. Disease relapse remains a major cause of transplant failure. T cell homeostasis is critical to determine the potency of the GVT effect. Recent studies have shown the association of the CTLA-4 polymorphisms with the outcome after HLA-identical sibling allogeneic HSCT. Methods In this study, we focused on four CTLA-4 polymorphisms, and analyzed the impact of donor genotypes and haplotypes on the conditions of 152 acute leukemia patients (ALL 83) after related HLA-haplotype- mismatched transplantation. The four SNP genotypes (−1661, −318, CT60 and +49) were determined by TaqMan SNP genotyping assays. Results ALL recipients of donors with +49 GG showed significantly lower OS (67.7 vs. 90.3 %, P = 0.015) than those with GA+AA. Multivariate analyses showed that +49 GG was an independent risk factor for OS (HR: 0.306, 95 % CI 0.111–0.842, P = 0.022) .23 ALL patients receiving mDLI showed significantly lower OS with +49 GG donor than those with GA+AA (30.0 vs. 83.1 %, P = 0.003). The haplotype analysis revealed only three haplotypes in the donor population −1661/−318/CT60/+49 i.e., ACGG, ACAA and GTGA, the frequencies were 64.1, 19.4 and 16.5 %, respectively. Donors with and without the ACGG/ACGG haplotype had the same effect on transplant outcomes as those with +49 GG and +49 GA+AA. Conclusion In summary, the CTLA-4 +49 GG and the haplotype ACGG/ACGG reduced the overall survival in ALL after allo-HSCT from the related HLA-haplotype-mismatched donor, knowledge of the CTLA-4 polymorphism and haplotype may provide useful information for donor selection and individual application of immunosuppressive agents and immunotherapy.

Abstract
BACKGROUND Chronic obstructive pulmonary disease (COPD) is associated with poor prognosis and a high health care burden. The incidence of asthma and COPD overlap syndrome is increasing, and contributes to a high financial burden and poor prognosis. OBJECTIVE To investigate clinical features of the overlap syndrome among Asian patients and to analyse its impact on hospitalisation due to respiratory problems or death compared to COPD alone. DESIGN We performed a retrospective cohort analysis of 2933 COPD patients presenting at the Asan Medical Center from 1 January 2000 to 31 December 2009. Kaplan-Meier and Cox proportional hazard models were used to analyse the significance of clinical parameters, including age, sex, smoking history, body mass index (BMI), severity of airflow limitation, airway obstruction reversibility and overlap syndrome with hospitalisation due to respiratory problems or death. RESULTS Overlap syndrome patients were older, included smaller proportions of males and of smokers and had lower forced expiratory volume in 1 s (FEV1) (% predicted). Shorter hospitalisation-free and survival periods were noted among overlap syndrome patients. Overlap syndrome was significantly associated with risk of hospitalisation due to respiratory problems after adjusting for age, smoking history, BMI, FEV1 (% predicted) and changes in FEV1 (P < 0.001). CONCLUSION Asthma and COPD overlap syndrome is associated with a higher risk of hospitalisation due to respiratory problems than COPD alone.

Abstract
BACKGROUND The association of the donor characteristics with the immune cell composition in second allografts remains poorly understood. In this study, we investigated retrospectively the effects of the donor characteristics on the immune cell composition in second allografts. STUDY DESIGN AND METHODS The immune cell composition in second allografts of granulocyte colony-stimulating factor (G-CSF) mobilized peripheral blood harvests from 100 healthy donors (male, 47, female, 53; median age, 39 years old) who underwent a second-time donation were correlated with their donor characteristics. RESULTS The median counts of CD3(+) T cells, CD4(+) T cells, CD8(+) T cells, CD3(+) CD4(-) CD8(-) T cells and monocytes in allografts were 150·17 × 10(6) /kg, 82·57 × 10(6) /kg, 48·02 × 10(6) /kg and 24·97 × 10(6) /kg, respectively. Multivariate analysis showed that the number of lymphocytes and platelets pre-first collection of G-CSF mobilized blood (FM) was strongly associated with the number of total lymphocytes (for lymphocytes, P = 0·003; for platelets, P = 0·012), CD3(+) T cells (for lymphocytes, P = 0·009; for platelets, P = 0·004) and CD3(+) CD4(+) T cells (for lymphocytes, P = 0·035; for platelets, P = 0·004) in the second allograft. The donor's BMI was negatively related to the number of CD3(+) T cells (P = 0·022) and CD3(+) CD4(+) T cells (P = 0·026) in the second allograft. The donor weight was negatively associated with the number of CD3(+) CD4(-) CD8(-) T cells (P = 0·015) in the second allograft, while the pre-FM white blood cell count showed a positive correlation (P = 0·009). CONCLUSION The results demonstrate the impact of the donor characteristics, including pre-FM platelet count and lymphocyte count, donor BMI and weight, on the immune cell composition in the second allograft.

Abstract
Cytokinesis, the physical separation of daughter cells at the end of cell cycle, is commonly considered a highly stereotyped phenomenon. However, in some specialized cells this process may involve specific molecular events that are still largely unknown. In mammals, loss of Citron-kinase (CIT-K) leads to massive cytokinesis failure and apoptosis only in neuronal progenitors and in male germ cells, resulting in severe microcephaly and testicular hypoplasia, but the reasons for this specificity are unknown. In this report we show that CIT-K modulates the stability of midbody microtubules and that the expression of tubulin β-III (TUBB3) is crucial for this phenotype. We observed that TUBB3 is expressed in proliferating CNS progenitors, with a pattern correlating with the susceptibility to CIT-K loss. More importantly, depletion of TUBB3 in CIT-K-dependent cells makes them resistant to CIT-K loss, whereas TUBB3 overexpression increases their sensitivity to CIT-K knockdown. The loss of CIT-K leads to a strong decrease in the phosphorylation of S444 on TUBB3, a post-translational modification associated with microtubule stabilization. CIT-K may promote this event by interacting with TUBB3 and by recruiting at the midbody casein kinase-2α (CK2α) that has previously been reported to phosphorylate the S444 residue. Indeed, CK2α is lost from the midbody in CIT-K-depleted cells. Moreover, expression of the nonphosphorylatable TUBB3 mutant S444A induces cytokinesis failure, whereas expression of the phospho-mimetic mutant S444D rescues the cytokinesis failure induced by both CIT-K and CK2α loss. Altogether, our findings reveal that expression of relatively low levels of TUBB3 in mitotic cells can be detrimental for their cytokinesis and underscore the importance of CIT-K in counteracting this event.

Abstract
Central venous catheterization is a common diagnostic and therapeutic procedure in modern clinical practice. Pseudoaneurysms of the subclavian artery are rare and usually occur immediately after the causative event, whether the cause was trauma or a medical procedure. Here, we report a case of a 71-year-old woman with delayed presentation of catheter-related subclavian pseudoaneurysm. The patient’s symptoms began two weeks after the initial catheterization, probably because of slow leakage of blood from the injured subclavian artery caused by incomplete compression of the puncture site and uremic coagulopathy. She was successfully treated with ultrasound-guided thrombin and angiography-guided histoacryl injection without stent insertion or surgery.
Keywords: butyl 2-cyanacrylate; pseudoaneurysm; subclavian; thrombin.

Abstract
BACKGROUND In this study, we aimed to identify demographic and clinical variables that correlate with perceived information provision among cancer patients and determine the association of information provision with decisional conflict (DC). PATIENTS AND METHODS We enrolled a total of 625 patients with cancer from two Korean hospitals in 2012. We used the European Organization for Research and Treatment of Cancer (EORTC) quality-of-life questionnaire (QLQ-INFO26) to assess patients' perception of the information received from their doctors and the Decisional Conflict Scale (DCS) to assess DC. To identify predictive sociodemographic and clinical variables for adequate information provision, backward selective logistic regression analyses were conducted. In addition, adjusted multivariate logistic regression analyses were carried out to identify clinically meaningful differences of perceived level of information subscales associated with high DC. RESULTS More than half of patients with cancer showed insufficient satisfaction with medical information about disease (56%), treatment (73%), other services (83%), and global score (80%). In multiple logistic regression analyses, lower income and education, female, unmarried status, type of cancer with good prognosis, and early stage of treatment process were associated with patients' perception of inadequate information provision. In addition, Information about the medical tests with high DCS values clarity [adjusted odds ratio (aOR), 0.54; 95% confidence interval (CI) 0.30-0.97] and support (aOR, 0.53; 95% CI 0.33-0.85) showed negative significance. For inadequate information perception about treatments and other services, all 5 DCS scales (uncertainty, informed, values clarity, support, and effective decision) were negatively related. Global score of inadequate information provision also showed negative association with high DCS effective decision (aOR, 0.43; 95% CI 0.26-0.71) and DCS uncertainty (aOR, 0.46; 95% CI 0.27-0.77). CONCLUSION This study found that inadequate levels of perceived information correlated with several demographic and clinical characteristics. In addition, sufficient perceived information levels may be related to low levels of DC.

Abstract
Objectives A carbapenem-resistant Acinetobacter calcoaceticus-Acinetobacter baumannii complex (CRA complex) infection is one of most the difficult infections to control worldwide. We evaluated the long-term effects of infection control interventions on the incidence densities of healthcare-associated infection (HAI) and CRA complex infection, and the rates of Acinetobacter calcoaceticus-Acinetobacter baumannii complex bacteremia (AB). Patients and methods We performed a cross-sectional analysis at the Changhua Christian Hospital from January 2002 to December 2013. Interventions for infection control were implemented from 2002 to 2009 (period 1). From 2010 to 2013 (period 2), infection control programs were improved by in-service education and a hand hygiene campaign to prepare for international and national hospital accreditation. The effectiveness of infection and antibiotic control programs was assessed according to the incidence densities of HAI and CRA complex, rates of CRA complex and of AB, chlorhexidine consumption density, and defined daily dose of antibiotics. Results The incidence density of HAI decreased from 4.56‰ to 1.52‰ from periods 1 to 2 (P < 0.001). Likewise, the incidence of AB decreased from 177.79 to 137.76 per person-years per 100,000 admissions (P < 0.001). The incidence density of CRA complex ranged from 3.17–7.38‰. The chlorhexidine consumption density increased from 5.5 to 45.5 L per 1000 patient-days (P < 0.001). The consumption of piperacillin-tazobactam was lower in period 2 than in period 1 (P < 0.001). Conclusion Education for infection control programs, hand hygiene campaigns, and antibiotics control programs may decrease the incidence density of AB and HAI, and may help control CRA complex infection.

Abstract
Relapse of Ph chromosome-positive ALL (Ph(+)ALL) results from the persistence of leukemia-propagating cells (LPCs). In Ph(+)ALL, a xenograft assay recently determined that LPCs are enriched in the CD34(+)CD38(-)CD58(-) fraction. Therefore, the prognostic significance of LPCs in Ph(+)ALL subjects after allogeneic hematopoietic SCT (allo-HSCT) was investigated. A total of 80 consecutive adults with Ph(+)ALL who underwent allo-HSCT were eligible. A multi-parameter flow cytometry analysis examining CD58-FITC/CD10-PE/ CD19-APC-Cy7/CD34-PerCP/CD45-Vioblue/ CD38-APC on gated leukemia BM blasts was performed at diagnosis. Based on the original blast phenotypes, subjects were stratified into the CD34(+)CD38(-)CD58(-)group (N=15) and other phenotype group (N=65). During minimal residual disease monitoring, significantly higher levels of BCR/ABL transcripts were detected in subjects in the CD34(+)CD38(-)CD58(-) group than in other phenotype group, especially at 3 months post HSCT. In addition, CD34(+)CD38(-)CD58(-)LPCs are directly correlated with a higher 3-year cumulative incidence of relapse (CIR) and worse leukemia-free survival (LFS) and OS. Multivariate analyses indicated that presence of CD34(+)CD38(-)CD58(-) LPCs at diagnosis, and BCR-ABL reduction at 3 months post HSCT were independent risk factors for relapse, LFS and OS. Our data suggest that presence of CD34(+)CD38(-)CD58(-) LPCs at diagnosis allows rapid identification of high-risk patients for relapse after allo-HSCT.

Abstract
BACKGROUND AND PURPOSE Inflammatory processes including autoimmune diseases which ignite endothelial dysfunction and atherosclerosis may promote development of cardiovascular diseases including ischaemic stroke. This study aimed to evaluate whether multiple sclerosis (MS) increases stroke risk. METHODS A national insurance claim data set of 22 million enrollees in Taiwan was used to identify 1174 patients with MS and 4696 randomly selected age- and gender-matched controls from 1 January 1997 to 31 December 2010. Both cohorts were followed up until the occurrence of stroke or censor. Relevant covariates, such as age, gender, hypertension, diabetes, hyperlipidaemia, coronary artery disease, congestive heart failure and pregnancy, were included for further survey. The hazard ratio (HR) of stroke was assessed using a Cox proportional hazards regression model. RESULTS After adjusting for the relevant covariates, the MS cohort had an increased risk of stroke (adjusted HR = 12.1 for 1 year; adjusted HR = 4.69 for 2-5 years) compared with the control cohort within 5 years of follow-up. Amongst participants without comorbidities, the MS cohort was still at a greater stroke risk than the control cohort [HR 4.93, 95% confidence interval (CI) 2.85-8.55]. Moreover, in the population aged ≤40, MS was associated with a significantly increased risk of stroke (HR 12.7, 95% CI 3.44-46.7). CONCLUSIONS Multiple sclerosis is declared to be associated with an increased risk in developing stroke, which requires closer attention to this group of patients for stroke prevention, especially in the younger population.

Abstract
The objective of this study was to analyze the oncological and functional outcomes after the surgical treatment of parotid cancer. We reviewed 80 primary parotid carcinomas retrospectively. A superficial parotidectomy was performed in 10 patients; 27 patients underwent total parotidectomy and 43 patients underwent radical parotidectomy. A facial-facial nerve anastomosis was chosen for the facial nerve reconstruction in eight patients, while an interpositional graft was selected in 24 patients. The overall N-positive rate of pathology was 21.3%. The rate of occult metastasis was 8.1%. High-grade carcinoma and lymphovascular emboli were independent factors for nodal metastasis. The 5-year disease-free survival and overall survival rates were 79.7% and 78.8%, respectively. Preoperative facial nerve palsy and extraparenchymal invasion were the independent factors associated with poor disease-free survival. Of the 41 patients in the facial nerve preservation group, 13 (31.7%) had transient facial nerve paresis. In the facial nerve sacrifice group of 39 cases, (sub)total recovery (House-Brackmann grade I/II) occurred in 14 (35.9%), partial recovery (House-Brackmann grade III/IV) in 13 (33.3%), and no recovery (House-Brackmann grade V) in 12 (30.8%). Facial nerve palsy upon presentation and extraparenchymal invasion indicate a grave prognosis. Facial nerve function after proper reconstruction is tolerable.

Abstract
We investigate by angle-resolved photoemission the electronic structure of in situ grown tetragonal CuO, a synthetic quasi-two-dimensional edge-sharing cuprate. We show that, in spite of the very different nature of the copper oxide layers, with twice as many Cu in the CuO layers of tetragonal CuO as compared to the CuO(2) layers of the high-T(c) cuprates, the low-energy electronic excitations are surprisingly similar, with a Zhang-Rice singlet dispersing on weakly coupled cupratelike sublattices. This system should thus be considered as a member of the high-T(c) cuprate family, with, however, interesting differences due to the intralayer coupling between the cupratelike sublattices.

Abstract
Porphyromonas gingivalis is a bacterial species that causes destruction of periodontal tissues. Additionally, previous evidence indicates that GroEL from P. gingivalis may possess biological activities involved in systemic inflammation, especially inflammation involved in the progression of periodontal diseases. The literature has established a relationship between periodontal disease and cancer. However, it is unclear whether P. gingivalis GroEL enhances tumor growth. Here, we investigated the effects of P. gingivalis GroEL on neovasculogenesis in C26 carcinoma cell-carrying BALB/c mice and chick eggs in vivo as well as its effect on human endothelial progenitor cells (EPC) in vitro. We found that GroEL treatment accelerated tumor growth (tumor volume and weight) and increased the mortality rate in C26 cell-carrying BALB/c mice. GroEL promoted neovasculogenesis in chicken embryonic allantois and increased the circulating EPC level in BALB/c mice. Furthermore, GroEL effectively stimulated EPC migration and tube formation and increased E-selectin expression, which is mediated by eNOS production and p38 mitogen-activated protein kinase activation. Additionally, GroEL may enhance resistance against paclitaxel-induced cell cytotoxicity and senescence in EPC. In conclusion, P. gingivalis GroEL may act as a potent virulence factor, contributing to the neovasculogenesis of tumor cells and resulting in accelerated tumor growth.

Abstract
INTRODUCTION Cerebral infarction in tuberculous meningitis is a major risk factor for permanent disability. This study assessed the clinical presentation of tuberculous meningitis and risks factors for cerebral infarction. OBSERVATION Thirty-eight adult patients with tuberculous meningitis were studied between 2002 and 2006. Clinical, radiological, and laboratory data of patients with cerebral infarction were compared with those of patients without cerebral infarction. Patients with cerebral infarction were significantly older (65.1 vs 52.1years), had higher risk assessment scores (3.7 vs 2.2), and more often had basal meningeal enhancement on imaging (92.3% vs 60.0%), mild to moderate sequelae (69.2% vs 4%), an overall poor brain outcome (69.2% vs 8%), aspirin prescription (84% vs 8%), and neurosurgical intervention for hydrocephalus (54.0% vs 16.0%). Cerebral infarction patients were also more likely to have experienced doctor-related delays in antituberculosis (61.5% vs 36%) and corticosteroid (61.5% vs 32%) therapy. DISCUSSION AND CONCLUSION The Framingham risk score would be an option for tuberculous meningitis patients to access cerebral infarction risk. Contrast-enhanced brain imaging is helpful for exploring basal meningeal enhancement, in order to obtain an early diagnosis. Antituberculosis, corticosteroid, and aspirin therapies should be started immediately when tuberculous meningitis is suspected.

Abstract
Background: Conflicting results have been reported regarding the predicative roles of alloreactive natural killer (NK) cells on the outcomes of transplantation in leukaemia patients. Methods: We prospectively analysed the human leukocyte antigen (HLA) typing of donor–recipient pairs and the KIR typing of the donors in 97 CML patients to address the predictive roles of NK cells in relapse undergoing T-cell-replete haploidentical transplantation. Results: Patients with class I ligands for the donor-inhibitory KIR gene exhibited decreased molecular and haematologic relapse rates (P=0.003 and P=0.015, respectively). There was a significantly reduced risk of molecular and haematologic relapse in patients with HLA-C1C2 or C2C2 who accepted donors with KIR2DS1 or in patients with HLA-Bw4 who accepted donors with KIR3DS1 (‘recipient with relevant KIR ligand for donor-activating KIR', n=25), compared with the remaining transplants (n=72, P=0.009 and P=0.009, respectively). In addition, the presence of class I ligand in the recipients of donor-activating KIR contributed to a decreased relapse rate in patients lacking class I ligand in the recipient of donor-inhibitory KIR (P=0.04 and P=0.03, respectively). Conclusions: This study suggests that the presence of class I ligands for the donor-activating or donor-inhibitory KIR gene in the recipient might confer some protection against leukaemic relapse in T-cell-replete haploidentical transplantation.

Abstract
BACKGROUND We explore whether cardiologist service volume, hospital level and percutaneous coronary intervention (PCI) are associated with medical costs and acute myocardial infarction (AMI) mortality. METHODS From the 1997-2010 Taiwan National Health Insurance Research Database of the National Health Research Institute, we identified AMI patients and performed multiple regression analyses to explore the relationships among the different hospital levels and treatment factors. RESULTS We identified 2942 patients with AMI in medical centers and 4325 patients with AMI in regional hospitals. Cardiologist service volume, performing PCI and medical costs per patient were higher in medical centers than in regional hospitals (P < 0.0001). However, the two hospital levels did not differ significantly in in-hospital mortality (P = 0.1557). Post hoc analysis showed significant differences in in-hospital mortality rate and in medical costs among the eight groups subdivided on the basis of hospital level, cardiologist service volume, and whether PCI was performed (P < 0.001 and P = 0.001, respectively). CONCLUSIONS These results highlight the importance of encouraging hospitals to develop PCI capability and increase their cardiologist service volume after taking medical costs into account. Transferring AMI patients to hospitals with higher cardiologist service volume and PCI performed can also be very important.

Abstract
SETTING Risk of pneumonia in chronic obstructive pulmonary disease (COPD) patients due to comorbid pulmonary disease is not well understood. OBJECTIVE To compare factors associated with risk of community-acquired pneumonia (CAP) in COPD patients for those with and without lung cancer, bronchiectasis and/or history of active tuberculosis. DESIGN Retrospective chart review of patients diagnosed with COPD (forced expiratory volume in 1 second/forced vital capacity < 0.70) between 2006 and 2010, including patient characteristics, occurrence of CAP and type of inhalation treatment. Pneumonia-free survivals were assessed using Kaplan-Meier curves. Factors associated with CAP were assessed using Cox's proportional hazard regression and expressed as adjusted hazard ratios (aHRs) with 95% confidence intervals (CIs). RESULTS Of 2630 patients, 402 (15.3%) developed CAP during follow-up. The likelihood of CAP increased with increased age (aHR 1.03, 95%CI 1.02-1.04), lower body mass index (BMI; aHR 0.97, 95%CI 0.95-1.00), lung cancer (aHR 3.81, 95%CI 2.88-5.05), bronchiectasis (aHR 2.46, 95%CI 1.70-3.55) and inhaled corticosteroid (ICS) containing treatment (aHR 1.60, 95%CI 1.30-1.96). ICS-containing treatment was associated with increased risk of CAP only for patients without comorbid pulmonary disease (aHR 1.68, 95%CI 1.30-2.17). CONCLUSION For COPD patients: 1) increased age, low BMI, lung cancer and bronchiectasis may increase the risk of CAP, and 2) without respiratory comorbid disease, ICS use increases the risk of CAP.

Abstract
We report a unique approach for the inclusion of size-tunable (7-50 nm), spherical Ge quantum dots (QDs) into gate stacks of metal-oxide-semiconductor (MOS) diodes, through selective oxidation of SiGe layers over the buffer layer of Si3N4 deposited over the Si substrate. In this complementary MOS (CMOS)-compatible approach, we successfully realized high performance nm scale Ge-QD MOS photodetectors with high figures of merit of low dark current density (1.5 × 10(-3) mA cm(-2)), superior photo-current-to-dark current ratio (13 500), high photoresponsivity (2.2 A W(-1)), and fast response time (5 ns), which are ready for direct integration with Si CMOS electronic circuits. Most importantly, the detection wavelength of the Ge QDs is tunable from near infrared to near ultraviolet by reducing the QD size from 50 to 7 nm as well as the optimal photoresponsivity is tailored by the Ge QD size and the effective thickness of gate dielectrics.

Abstract
Chronic inflammation is a well-known risk factor for type 2 diabetes mellitus (T2DM). The influence of chronic osteomyelitis (COM), an inflammatory disease, on the risk of developing T2DM remains unknown. This study investigated the risk of developing T2DM among COM patients. Using a retrospective cohort study, we identified 20,641 patients with COM and 82,564 age- and sex-matched controls for comparison from the Taiwan National Health Insurance Database (NHIRD) from 1997 to 2010. We followed up the COM cohort and the comparison cohort to compare the incidences of diabetes (ICD-9-CM code 250) until the end of 2010 or until the patients were censored because of death or withdrawal from the insurance program. The diabetes risk was analyzed using the Cox proportional hazards regression model. The incidence of T2DM was 1.6-fold higher in the group of COM patients than in the comparison group (29.1 vs. 18.2 per 10,000 person-years). The COM patients exhibited a higher diabetes risk [adjusted hazard ratio (aHR) = 1.64, 95 % confidence interval (CI) = 1.44-1.87] after controlling for the baseline and comorbidities. Younger and higher income patients exhibited a higher COM-to-reference incidence rate ratio (IRR) for T2DM compared with that of their counterparts. We also observed an increased risk of T2DM in COM patients with comorbidities (aHR = 1.70, 95 % CI = 1.47-1.96) compared with that of their non-COM counterparts. This is the first study to report the association between COM and an increased risk of developing T2DM, particularly among younger and higher income patients.

Abstract
BACKGROUND AND PURPOSE Our aim was to investigate the influence of admission dehydration on the discharge outcome in acute ischaemic and hemorrhagic stroke. METHODS Between January 2009 and December 2011, 4311 ischaemic and 1371 hemorrhagic stroke patients from the stroke registry of Chang Gung healthcare system were analyzed. The eligible patients were identified according to inclusion/exclusion criteria. In total, 2570 acute ischaemic and 573 acute hemorrhagic stroke patients were finally recruited. According to the blood urea nitrogen (BUN) to creatinine (Cr) ratio (BUN/Cr), these patients were divided into dehydrated (BUN/Cr ≥ 15) and non-dehydrated (BUN/Cr < 15) groups. Demographics, admission costs and discharge outcomes including modified Rankin scale (mRS) and Barthel index (BI) were examined. Data were analyzed using multivariate analysis of two-stage least squares including logistic and linear regression. RESULTS Acute ischaemic stroke with admission dehydration had higher infection rates (P = 0.006), worse discharge BI (62.8 ± 37.4 vs. 73.4 ± 32.4, P < 0.001, adjusted P < 0.001), worse mRS (2.7 ± 1.6 vs. 2.3 ± 1.5, P < 0.001, adjusted P = 0.009) and higher admission costs (2470.8 ± 3160.8 vs. 1901.2 ± 2046.8 US dollars, P < 0.001, adjusted P = 0.013) than those without dehydration. However, acute hemorrhagic stroke with or without admission dehydration showd no difference in admission costs (P = 0.618) and discharge outcomes (BI, P = 0.058; mRS, P = 0.058). CONCLUSION Admission dehydration is associated with worse discharge outcomes and higher admission costs in acute ischaemic stroke but not in hemorrhagic stroke.

Abstract
AIM Periodontal disease encompasses gingivitis and periodontitis, which exerts systemic effects. We conducted a population-based study to evaluate the association between periodontal disease and the risk of cancer. METHODS We used insurance claims data from 1997 to 2010, accessing a database of 1 million randomly selected insurants in Taiwan. All patients were older than 20 and newly diagnosed with periodontitis between 1 January 1997 and 31 December 2010. The comparison cohort comprised patients older than 20, who were newly diagnosed with gingivitis in the same period. Both cohorts were followed until a cancer diagnosis, lost to follow-up, death, termination of insurance, or the end of 2010. RESULTS The incidence rate of cancer was 1.14 times higher in the study cohort than in the comparison cohort [confidence interval (CI) = 1.11-1.17]. The adjusted hazard ratio (HR) was 1.05 (95% CI = 1.00-1.11). A multivariable analysis showed that the periodontitis patients exhibited an elevated risk of developing oral cancer (adjusted HR = 1.79, 95% CI = 1.42-2.25). CONCLUSION The findings indicated that patients in the periodontitis cohort exhibited a higher risk of developing oral cancer than those in the gingivitis cohort.

Abstract
This retrospective population-based study aimed to investigate associations between erectile dysfunction (ED) and the irritable bowel syndrome (IBS) using a Taiwanese cohort. We identified 17 608 male patients who were newly diagnosed with IBS from 1997 to 2010. The date that the diagnosis of IBS had been made was the index date. IBS patients with a history of ED before the index date or with incomplete demographic information were excluded. 70 432 age-matched subjects without IBS were selected as comparison cohort. Both cohorts were followed until the end of 2010 or censored. Cox proportional hazard regression model was used to estimate the effects of IBS on ED risks. The incidence rate ratio of ED in the IBS cohort was 2.92 times higher than that in the non-IBS cohort (29.5 vs. 10.1 per 10 000 person-years), with an adjusted hazard ratio (aHR) of 2.58 (95% confidence interval [CI]: 2.24-2.98). The risk of ED increased with increasing age and number of comorbidities. Patients with depression were at a higher risk of ED (aHR: 1.97; 95% CI: 1.49-2.63) compared with the subjects without depression. IBS patients had a higher risk of developing ED compared with non-IBS subjects. Ageing and comorbidities including diabetes, cardiovascular disease, chronic kidney disease and depression were associated with the risk of ED.

Abstract
To evaluate the effect of the different doses of antithymocyte globulin (ATG) on the incidence of acute GVHD among patients receiving hematopoietic SCT without ex vivo T-cell-depletion from haploidentical donors, 224 patients with standard-risk hematological malignancy were randomized in this study. One hundred and twelve patients received 6 mg/kg ATG, whereas the remaining patients received 10 mg/kg ATG. This study was registered at http://www.chictr.org as No. ChiCTR-TRC-11001761. The incidence of grade III-IV acute GVHD was higher in the ATG-6 group (16.1%, 95% confidence interval (CI), 9.1-23.1%) than in the ATG-10 group (4.5%, CI, 0.7-8.3%, P=0.005, 95% CI for the difference, -19.4% to -3.8%). EBV reactivation occurred more frequently in the ATG-10 group (25.3%, 17.1-33.5%) than in the ATG-6 group (9.6% (4.0-15.2%), P=0.001). The 1-year disease-free survival rates were 84.3% (77.3-91.3%) and 86.0% (79.2-92.8%) for the ATG-6 group and ATG-10 groups, respectively (P=0.88). In conclusion, although 6 mg/kg ATG applied in haploidentical transplantation decreased the risk of EBV reactivation compared with 10 mg/kg ATG, this treatment exposes patients to a higher risk for severe acute GVHD.

Abstract
UNLABELLED Chronic use of morphine is a risk factor for endocrinopathy and osteoporosis. Bisphosphonates accentuated the protective effect to develop osteoporosis in female patients with malignancy with morphine treatment. INTRODUCTION This study investigates the risk of osteoporosis associated with morphine use by comparing the incidence of osteoporosis in female cancer patients treated with and without morphine. METHODS A population-based nested case-control retrospective analysis was performed using the Longitudinal Health Insurance Database 2000 and Registry for Catastrophic Illness Patients of Taiwan. A malignancy cohort of 12,467 female patients without a history of osteoporosis during 1998-2010, and then 639 patients who subsequently developed osteoporosis as the osteoporosis group, were evaluated. Control-group patients were selected from the malignancy cohort without osteoporosis and frequency matched to each osteoporosis case 2:1 for age, year of cancer diagnosis, and index year. Logistic regression was used to estimate the odds ratios and 95% confidence intervals, and the multivariable model was applied to control for age. RESULTS Female cancer patients who received morphine had a 10% lower risk of developing osteoporosis than non-morphine users, but this risk reduction was not significant. For patients treated with bisphosphonates, the morphine group had significantly lower odds in developing osteoporosis than the non-morphine group. CONCLUSION Morphine treatment is not associated with the incidence of osteoporosis, and bisphosphonates accentuated the protective effect of morphine in the development of osteoporosis in female patients with malignancy in Taiwan.

Abstract
The reproductive biology of female bigeye tuna Thunnus obesus was assessed by examining 888 fish (ranging from 84·9 to 174·4 cm fork length, LF ) caught by Taiwanese offshore longliners in the western Pacific Ocean from November 1997 to November 1998 and November to December 1999 and 258 gonad samples from these fish. The overall sex ratio of the catch during the sampling differed significantly from 0·5, but males were predominant in sizes >140 cm LF . Reproductive activity (assessed by histology), a gonado-somatic index, and the size-frequency distributions of whole oocytes indicated that spawning occurred throughout the year and the major spawning season appeared to be from February to September. The estimated sizes at 50% maturity (LF50 ) of females was 102·85 cm (95% c.i.: 90·79-110·21 cm) and the smallest mature female was 99·7 cm LF . They are multiple spawners and oocytes develop asynchronously. The proportion of mature (0·63) and reproductively active (0·70) females with ovaries containing postovulatory follicles indicated that they spawn almost daily. Batch fecundity for 15 females with the most advanced oocytes (>730 µm) ranged from 0·84 to 8·56 million eggs (mean ± s.d. = 3·06 ± 2·09). The relationships between batch fecundity (FB , in millions of eggs) and LF (cm) and round mass (MR , kg) were FB=9·91×10-14LF6·38 (r(2) = 0·84) and FB=8·89×10-4MR2·05 (r(2) = 0·80), respectively. The parameters estimated in this study are key information for stock assessments of T. obesus in the western Pacific Ocean and will contribute to the conservation and sustainable yield of this species.

Abstract
BACKGROUND Functional outcome and the risk factors for stroke survivors have explored in previous study. However, a comprehensive understanding of the patterns and critical risk factors of functional recovery is limited. AIM To explore the trajectory groups and determinants of functional recovery for ischemic stroke patients during 1 year after stroke. DESIGN Longitudinal study. SETTING Inpatient. POPULATION First-time stroke patients. METHOD A total of 367 first-time ischemic stroke patients from the Stroke Registry in the Chang Gung Hospital (SRICH) database were analyzed in this study. Study variables comprised demographic and disease characteristics, laboratory data, and functional outcome. The Latent Class Growth Analysis (LCGA) was used to identify various trajectory clusters and multinomial logistic regression was used to identify the predictors of functional recovery. RESULT Five trajectory clusters of functional recovery were identified using the Barthel Index. Among five clusters of functional recovery, nearly 18% of first-ever ischemic stroke patients maintained functional dependence, whereas 82% of stroke patients demonstrated functional recovery; and the significant recovery time totaled three months after the stroke. Determinants for various trajectory clusters of functional recovery were body mass index and serum albumin level, especially a higher serum albumin concentration predicted a more favorable functional recovery. CONCLUSION Our findings suggest that diverse functional recovery clusters persisted and serum albumin concentration at admission was a critical assessment factor. CLINICAL REHABILITATION: Such information could be useful for identifying the different rehabilitation needs of varying trajectory groups and for effectively improving functional ability among the ischemic stroke population.

Abstract
This paper presents a population-based retrospective cohort study to identify the differences in secondary primary cancer (SPC) among hypopharyngeal, laryngeal, and other sites of head and neck cancer (HNC). Data were collected from the Taiwan National Health Insurance Research Database (NHIRD) for the period 1979-2010. The study cohort comprised 5914 newly diagnosed hypopharyngeal and laryngeal patients from the registry of the Catastrophic Illness Patients Database (CIPD). The comparison cohort comprised 5914 patients with other sites of HNC. We used a multivariate Cox proportional-hazards regression model to assess the risk of developing SPC. The incidence of SPC in the study cohort was 68% higher compared with the comparison cohort (23.9 vs. 14.2 per 1000 person-years, Incident Rate Ratio = 1.68). The study cohort had a higher adjusted hazard ratio (HR) in oesophageal cancer (HR = 3.47) and lung cancer (HR = 1.89). The difference in SPC incidence between the study and comparison cohort was significant.

Abstract
Oxygen vacancies created in anatase TiO(2) by UV photons (80-130 eV) provide an effective electron-doping mechanism and induce a hitherto unobserved dispersive metallic state. Angle resolved photoemission reveals that the quasiparticles are large polarons. These results indicate that anatase can be tuned from an insulator to a polaron gas to a weakly correlated metal as a function of doping and clarify the nature of conductivity in this material.
