Abstract
Background: Perioperative cerebral hypoperfusion (CH) is common, although the underlying mechanism of cognitive impairment that results due to perioperative cerebral hypoperfusion remains to be determined. Isoflurane anaesthesia induces neuronal injury via endoplasmic reticulum (ER) stress, whereas a sub-anaesthetic dose of propofol improves postoperative cognitive function. However, the effects of the combination of isoflurane plus propofol, which is a common aesthetic combination administered to patients, on ER stress and cognition remain unknown.
Methods: We sought to determine the effects of isoflurane plus propofol on ER stress and cognitive function in rats insulted by cerebral hypoperfusion. Ligation of the bilateral common carotid arteries (CCA) was adopted to develop the cerebral hypoperfusion rat model. A second surgery, open reduction and internal fixation (ORIF), requiring general anaesthesia, was performed 30 days later so that the effects of anaesthetics on the cognitive function of CH rats could be assessed. Rats received isoflurane alone (1.9%), propofol alone (40 mg·kg-1·h-1) or a combination of isoflurane and propofol (1% and 20 mg·kg-1·h-1 or 1.4% and 10 mg·kg-1·h-1). Behavioural studies (fear conditioning [FC] test), histological analyses (Nissl staining) and biochemical analyses (western blotting of the harvested rat brain tissues) were employed.
Results: The combination of 1% isoflurane plus 20 mg·kg-1·h-1 propofol did not aggravate cognitive impairment or ER stress in ageing rats with CH that were further subjected ORIF surgery.
Conclusions: These data suggest that ER stress contributes to the underlying mechanism of cognitive impairment and that the combination of isoflurane and propofol did not aggravate cognitive impairment and ER stress in ageing rats with CH that were further subjected ORIF surgery.

Abstract
Background: Hospital Information System implementation is complex and costly compared to other information systems. Therefore, the present study was conducted with the aim of designing and evaluating technical HIS requirements.
Methods: This study was conducted in 2016 in two parts: designing technical requirements and evaluating the HIS. The first part of the study was performed through the Delphi technique. In the second part of the study, evaluation of systems was done using a checklist based on the approved requirements.
Results: In the first part of the study, the final list of technical HIS requirements was designed with 73 items in four domains including ‘communication service’, ‘system architecture’, ‘security service’, and ‘system response time’. In the second part, the results of the evaluation indicated that the approved requirements had been observed in 63.8%, 65.5%, 72.4%, and 76.3% of the HIS software programs in the dimensions of ‘communication service’, ‘system architecture’, ‘security service’, and ‘system response time’, respectively.
Conclusions: The technical HIS evaluation tool was designed to be used in the evaluation and selection of the system. The evaluation results also indicated that the studied HISs were weaker in ‘communication service’ and ‘system architecture’ domains compared to the other two domains under study.

Abstract
Background
Esophageal squamous cell carcinoma (ESCC) is a highly malignant neoplasm. Glucocorticoid(GC)-Glucocorticoid receptor (GR) pathway plays pivotal roles in cellular response to various stresses of tumor cells including chemotherapy. However, the status of GC-GR pathway in ESCC, including its correlation with chemotherapeutic responses has remained largely unknown.
Method
GR, serum-and glucocorticoid-regulated kinase 1(Sgk1), and N-myc down regulation gene 1(NDRG1) were immunolocalized in 98 ESCC patients who had undergone esophagectomy following neoadjuvant chemotherapy(NAC) with 2 courses of 5-Fluorouracil(5-FU) + Cisplatin (CDDP). We also examined biopsy specimens before NAC in 42 cases and compared the results between those before and after NAC.
Results
Overall survival (OS) of the patients treated with surgery following NAC was significantly shorter in the group with high GR than that with low GR ( P = 0.0473). Both OS and disease-free survival (DFS) were significantly shorter in both Sgk1- and NDRG1-high groups than low groups (OS: Sgk1, P = 0.0055; NDRG1, P = 0.0021; DFS: Sgk1, P = 0.0240; NDRG1, P = 0.0086). When evaluating the findings in biopsy specimens before NAC, DFS was significantly shorter in the high Sgk1 group ( P = 0.0095), and both OS and DFS was shorter in high NDRG1 group (OS, P = 0.0233; DFS, P = 0.0006) than respective low groups. Among high NDRG1 group of biopsy specimens before NAC, the tumor reduction rate by NAC was significantly attenuated ( P = 0.021).
Conclusions
High status of GR, Sgk1, and NDRG1 in ESCC after NAC was significantly associated with over all worse prognosis and there were no significant changes in the status of those above before and after NAC. Therefore , increased activity of GC-GR pathway with enhanced induction of Sgk1 and NDRG1 in carcinoma cells plays pivotal roles in tumor progression and development of chemoresistance in ESCC patients undergoing NAC.

Abstract
Background

Outbreaks of norovirus infection can have detrimental impacts on long-term care facilities. This study investigated the incidence, clinical picture, treatment, resource use, and costs of norovirus gastroenteritis in long-term care facilities.

Methods

Nineteen facilities in Osaka and Kyoto, Japan participated in questionnaire surveys conducted between 2009 and 2011 regarding the incidence of norovirus gastroenteritis. From clinical charts, the characteristics, symptoms, and treatment of infected residents were analyzed. Total drug cost per infected resident was calculated by multiplying the unit price for each drug by the daily dose and the number of days administered and summing the costs for each drug (USD 1 = JPY 100).

Results

Over the 3-year period, 8 outbreaks of norovirus gastroenteritis occurred in 6 facilities. The mean clinical course of 107 infected residents in five facilities that granted permission to examine patients’ medical records was 4 days, with all but one resident presenting with vomiting and/or diarrhea, and 84 (79%) also presenting with associated symptoms. Of 107 infected residents, 72 (67%) were isolated. The proportion of infected residents isolated varied from 50% to 100% depending on the facility. Of the infected residents, 81 (76%) received some type of medication, the most common being infusion (67 patients, 63%) and antibiotics (30 patients, 28%). The median total cost of all drugs administered was USD 4.4, and the median drug cost per infected resident per day was USD 2.0. Total drug cost over the entire treatment period was the highest for antibiotics, at USD 8.6.

Conclusion

Clinical course was similar to those of norovirus cases examined at other facilities. The majority of infected residents received some type of medication. Although the economic burden was not large, not a few infected residents were given antibiotics, which are ineffective for norovirus.
Facilitators and Barriers of Managing Patients with Multiple Chronic Conditions in the Community: A Qualitative Study
Authors: Foo Kah Mun , Sundram Meena , Legido-Quigley Helena 
Published: February 2020

Abstract
Background
Approximately one-third of all adults worldwide are diagnosed with multiple chronic conditions (MCCs). The literature has identified several challenges facing providers and patients coping with managing MCCs in the community, yet few studies have considered their viewpoints in combination. A qualitative study involving healthcare providers and users was thus conducted to examine facilitators and barriers of managing patients with MCCs in the community in Singapore.
Methods
This study involves 26 semi-structured interviews with 10 physicians, 2 caregivers and 14 patients seeking treatment in the polyclinics that provide subsidised primary care services. Topic guides were developed with reference to the literature review, Chronic Care Model (CCM) and framework for patient-centred access to healthcare.
Results
Despite the perceived affordability and availability of the support system, some patients still encountered financial difficulties in managing care. These include inadequacy of the nation-wide medical savings scheme to cover outpatient treatment and medications. Half of healthcare users did not know where to seek help. While patients could access comprehensive services in polyclinics, those who did not visit the clinics might not receive timely care. Furthermore, patients reported long consultation waiting time.
Physicians were able to propose and drive quality improvement projects to improve care quality. However, there were challenges to delivering safe and quality care with limited consultation duration due to the need to manage high patient load and waiting time, inadequate communication with specialists to coordinate care, and resource constraints in managing complex patients.
Although providers could equip patients with self-management and lifestyle-related guidelines, patients’ actions are influenced by multiple factors, including work requirements, beliefs and environment.
Conclusions
There were barriers on care access, delivery and self-management. It is crucial to adopt a whole-of-society approach involving individuals, community, institutions and policymakers to improve and support MCC management. This study has also highlighted the importance of considering the different viewpoints of healthcare providers and users in policy formulation and community care planning.

Published: February 2020

Abstract
Background
Potato is the third most consumed crop in the world. Breeding for traits such as yield, product quality and pathogen resistance are main priorities. Identifying molecular signatures of these and other important traits is important in future breeding efforts. In this study, a progeny population from a cross between a breeding line, SW93-1015, and a cultivar, Désirée, was studied by trait analysis and RNA-seq in order to develop understanding of segregating traits at the molecular level and identify transcripts with expressional correlation to these traits. Transcript markers with predictive value for field performance applicable under controlled environments would be of great value for plant breeding.

Results
A total of 34 progeny lines from SW93-1015 and Désirée were phenotyped for 17 different traits in a field in Nordic climate conditions and controlled climate settings. A master transcriptome was constructed with all 34 progeny lines and the parents through a de novo assembly of RNA-seq reads. Gene expression data obtained in a controlled environment from the 34 lines was correlated to traits by different similarity indices, including Pearson and Spearman, as well as DUO, which calculates the co-occurrence between high and low values for gene expression and trait. Our study linked transcripts to traits such as yield, growth rate, high laying tubers, late and tuber blight, tuber greening and early flowering. We found several transcripts associated to late blight resistance and transcripts encoding receptors were associated to Dickeya solani susceptibility. Transcript levels of a UBX-domain protein was negatively associated to yield and a GLABRA2 expression modulator was negatively associated to growth rate.

Conclusion
In our study, we identify 100’s of transcripts, putatively linked based on expression with 17 traits of potato, representing both well-known and novel associations. This approach can be used to link the transcriptome to traits. We explore the possibility of associating the level of transcript expression from controlled, optimal environments to traits in a progeny population with different methods introducing the application of DUO for the first time on transcriptome data. We verify the expression pattern for five of the putative transcript markers in another progeny population.

Abstract
Background Microalgae, due to its well-recognized advantages have been gained renewed interest as potentially good feedstock for biodiesel. Production of fatty acid methyl esters (FAMEs) as a type of biodiesel was carried out from Chlorella vulgaris bio oil. Biodiesel was produced in the presence of nano-biocatalysts composed of immobilized lipase on functionalized superparamagnetic few-layer graphene oxide via a transesterification reaction. A hybrid of few-layer graphene oxide and Fe 3 O 4 (MGO) was prepared and characterized. The MGO was functionalized with 3-aminopropyl triethoxysilane (MGO-AP) as well as with a couple of AP and glutaraldehyde (MGO-AP-GA). The Rhizopus oryzae lipase (ROL) was immobilized on MGO and MGO-AP using electrostatic interactions as well as on MGO-AP-GA using covalent bonding. The supports, MGO, MGO-AP, and MGO-AP-GA, as well as Nano-biocatalyst, ROL/MGO, ROL/MGO-AP, and ROL/MGO-AP-GA, were characterized using FESEM, VSM, FTIR, and XRD. The few-layer graphene oxide was characterized using AFM and the surface charge of supports was evaluated with the zeta potential technique. The nano-biocatalysts assay was performed with an evaluation of kinetic parameters, loading capacity, relative activity, time-course thermal stability, and storage stability. Biodiesel production was carried out in the presence of nano-biocatalysts and their reusability was evaluated in 5 cycles of transesterification reaction. Results: The AFM analysis confirmed the few-layer structure of graphene oxide and VSM also confirmed that all supports were superparamagnetic. The maximum loading of ROL (70.2%) was related to MGO-AP-GA. The highest biodiesel conversion of 71.19% achieved in the presence of ROL/MGO-AP-GA. Furthermore, this nano-biocatalyst could maintain 58.77% of its catalytic performance after 5 cycles of the transesterification reaction and was the best catalyst in the case of reusability. Conclusions: In this study, the synthesized nano-biocatalyst based on bare and functionalized magnetic graphene oxide was applied and optimized in the process of converting microalgae bio-oil to biodiesel for the first time and compared with bare lipase immobilized on magnetic nanoparticles. Results showed that the loading capacity, kinetic parameters, thermal stability, and storage stability improved by the functionalization of MGO. The biocatalysts, which were prepared via covalent bonding immobilization of enzyme generally, showed better characteristics.

Published: February 2020

Abstract
Background: Overwhelmingly, women in Middle Eastern countries experience birth as dehumanising and disrespectful.Aim: To examine Jordanian women’s experiences and constructions of labour and birth in different settings (home, public and private hospitals in Jordan, and Australian public hospitals), over time and across generations. Method: A qualitative interpretive design was used. Data were collected by face-to-face semi-structured interviews with 27 Jordanian women. Of these women, 20 were living in Jordan (12 had given birth in the last five years and eight had birthed over 15 years ago) while seven were living in Australia (with birthing experience in both Jordan and Australia). Interview data were transcribed verbatim and analysed thematically.Results: Women’s birth experiences differed across settings and generations and were represented in the four themes: ‘Home birth: a place of comfort’; ‘Public Hospital: it’s what you do’; ‘Private Hospital: buying control’ and ‘Australian maternity care: a mixed experience’. In each theme, the concepts: Pain, Privacy, the Personal and to a lesser extent, Purity (cleanliness), were present but experienced in different ways depending on the setting (home, public or private hospital) and the country.Conclusions: The findings demonstrate how meanings attributed to labour and birth, particularly the experience of pain, are produced and reproduced in different settings, providing insights not only into the medical and institutional management of birth, but also the social context influencing decision-making around birth in Jordan and other Middle Eastern countries. In the public hospital environment in Jordan, women were treated in a dehumanised way with no privacy, no support for people and no access to the pain relief they wanted. This was in stark contrast to women birthing at home only one generation before. Change is urgently needed to offer humanised birth in the Jordanian maternity system,

Abstract
Acquired aplastic anemia (AA) is a rare hematologic disease characterized by a profound pancytopenia and hypocellular bone marrow. To comprehensively compare the efﬁcacy and safety of allogeneic hematopoietic stem cell transplantation (allo-HSCT) with immunosuppressive therapy (IST) as a front-line treatment for patients with AA. We searched the Medline, Embase, and Cochrane Registry of Controlled Trials databases from January 2000 to March 2019. Studies comparing allo-HSCT with IST as a first-line therapy for patients with AA were included. Fifteen studies including a total of 5336 patients were included in the meta-analysis. The pooled hazard ratio (HR) for overall survival (OS) was 0.4 (95% CI 0.074–0.733, P = 0.016, I2 = 58.8%) and the pooled HR for failure-free survival (FFS) was 1.962 (95% CI 1.43–2.493, P = 0.000, I2 = 0%). The pooled relative risk (RR) for overall response rate (ORR) was 1.691 (95% CI 1.433–1.996, P = 0.000, I2 = 11.6%). Although survival was significantly longer among AA patients undergoing first-line allo-HSCT compared to those undergoing first-line IST, the selection of initial treatment for patients with newly diagnosed AA still requires comprehensive evaluation of donor availability, patient age, expected quality of life, risk of disease relapse or clonal evolution after IST, and potential use of adjunctive eltrombopag.

Abstract
Objective: Low birth weight (LBW) is a major public health issue as it increases the risk of noncommunicable diseases throughout life. However, the genome-wide DNA methylation patterns of full-term LBW infants (FT-LBWs) are still unclear. This exploratory study aimed to analyze the DNA methylation differences in FT-LBWs compared with those in full-term normal birth weight infants (FT-NBWs) whose mothers were nonsmokers and had no complications. Initially, 702 Japanese women with singleton pregnancies were recruited. Of these, four FT-LBWs and five FT-NBWs were selected as references for DNA methylation analysis, and 862,260 CpGs were assessed using Illumina Infinium MethylationEPIC BeadChip. Gene ontology enrichment analysis was performed using DAVID v6.8 software to identify the biological functions of hyper- and hypomethylated DNA in FT-LBWs.
Results: 483 hyper-differentially methylated genes (DMGs) and 35 hypo-DMGs were identified in FT-LBW promoter regions. Hyper-DMGs were annotated to 11 biological processes; “macrophage differentiation” (e.g., CASP8), “apoptotic mitochondrial changes” (e.g., BH3), “nucleotide-excision repair” (e.g., HUS1), and “negative regulation of inflammatory response” (e.g., NLRP12 and SHARPIN). EREG was classified into “ovarian cumulus expansion” within the “organism growth and organization” category. Our data imply that LBW might be associated with epigenetic modifications, which regulate the immune system and cell maturation.

Abstract
Background: To evaluate the efficacy of submucosal injection of triamcinolone acetonide for the treatment of type II/III interstitial cystitis/bladder pain syndrome.
Methods: A retrospective analysis of the clinical data of type II/III interstitial cystitis/bladder pain syndrome patients treated in our department from April 2016 to August 2018 was conducted, and changes in International Prostate Symptom Scores and the Pelvic Pain and Urgency/Frequency symptom scale after surgery were evaluated to explore factors that may affect patient outcomes.
Results: A total of 27 female patients and 8 male patients were enrolled, with type II patients accounting for 62.9% of the sample, and the median follow-up duration was 31 months (range: 12-40 months). Twenty-two patients (74.3%) had significantly improved questionnaire scores at 4 weeks postoperatively. Treatment efficacy was sustained for at least 1 year in 15 patients, and persistent effectiveness was noted in 10 (28.6%) patients. Patients with an advanced age (p=0.015), high pain scores (p=0.040), and higher International Prostate Symptom Scores (p=0.037) and Pelvic Pain and Urgency/Frequency symptom scale scores (p=0.020) were more likely to benefit from submucosal injection of triamcinolone acetonide. Gender, disease duration, and the presence of Hunner’s lesions had no predictive value for treatment outcomes.
Conclusion: Submucosal injection of triamcinolone acetonide can improve the clinical symptoms and quality of life in both men and women with type II/III interstitial cystitis/bladder pain syndrome. Patients with an advanced age and more severe interstitial cystitis/bladder pain syndrome related symptoms may benefit more from triamcinolone acetonide injection.
