Association of vaspin rs2236242 with type 2 diabetes mellitus and obesity: a meta-analysis of case-control studies. J Diabetes Metab Disord 2023; 22:237-243. [PMID: 37255815 PMCID: PMC10225408 DOI: 10.1007/s40200-022-01119-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/05/2022] [Revised: 07/19/2022] [Accepted: 08/26/2022] [Indexed: 06/01/2023]
Abstract
Background Elevated circulating vaspin levels is linked with type 2 diabetes mellitus (T2DM) and obesity. The genetic basis of the association between vaspin rs2236242 and T2DM and obesity is still being investigated. We executed a meta-analysis to evaluate the magnitude of effect caused by vaspin rs2236242 on T2DM and obesity. Methods We searched Pubmed, Embase, MEDLINE, Scopus, Web of Science, and Google Scholar for relevant articles published up to 19 February 2022. Data were extracted and summary estimates of the association between vaspin rs2236242 and T2DM and obesity were assessed. Odds ratios (ORs) and confidence intervals (CIs) were used to measure the effect. Results This meta-analysis included 2206 cases and 2715 controls in the T2DM cohort, meanwhile 271 cases and 444 controls in the obesity cohort. The pooled estimates revealed no link between vaspin rs2236242 and T2DM, but allele-A was significantly higher in the controls of the obesity cohort, showing that this single nucleotide polymorphism (SNP) has a reduced obesity risk effect. Sensitivity analysis revealed no studies that would modify the estimates or the heterogeneity. Begg and Mazumdar's and Egger's tests indicated no substantial publication bias. Conclusion Our meta-analysis provides evidence of significant association between vaspin rs2236242 and reduced risk of obesity but not T2DM.

Impact of urinary calcium excretion on kidney, bone, and cardiovascular systems in patients with bone biopsy proven osteoporosis: a longitudinal long-term follow-up study. Osteoporos Int 2023; 34:763-774. [PMID: 36790470 DOI: 10.1007/s00198-023-06686-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/21/2022] [Accepted: 01/23/2023] [Indexed: 02/16/2023]
Abstract
UNLABELLED The impact of urine calcium on kidney, bone, and cardiovascular systems in osteoporosis is not well-known. In this 7-year-follow-up study, high urine calcium did not affect kidney function but increased risk of kidney stones, while low urine calcium increased cardiovascular diseases. Maintaining normal urine calcium is beneficial for bone health. PURPOSE Hypercalciuria is common in patients with osteoporosis. However, the long-term effect of urinary calcium excretion (UCaE) on patients' health is not well-examined. The current study aims to assess the impact of UCaE on kidney, bone, and cardiovascular outcomes in patients with bone biopsy proven osteoporosis. METHODS Longitudinal study of all patients with osteoporosis who underwent bone biopsy and 24-h urine collection between 2008 and 2015 in the University of Kentucky. DXA scans, serum markers, kidney function, and cardiovascular events were recorded until last clinic visit in 2021. Exclusion criteria were secondary osteoporosis or conditions that might substantially impact UCaE. The significant results in univariate analysis were confirmed in multi-variable regression models involving clinically important covariates that might impact patients' outcomes. RESULTS Study included 230 patients with mean follow-up of 7.2 ± 2.9 years. The mean age was 61 years, and the mean eGFR at baseline was 85 ± 19 ml/min/1.73 m2. Low bone turnover (LBT) was present in 57% and high bone turnover (HBT) in 43% of patients. Hypercalciuria was found in one-third of patients with no difference between LTB and HTB. UCaE correlated positively with eGFR but did not affect the rate of eGFR decline over time. Higher UCaE predicted kidney stones development. We observed U-shaped effect of UCaE on bone health. Hypercalciuria predicted loss of BMD at all sites, but also hypocalciuria was associated with higher loss in total hip BMD. Upper limb fractures were the most observed fractures, and their incidence was higher in patients with hyper- or hypo-calciuria. Lower UCaE independently predicted development of major adverse cardiac events (MACE) and cardiovascular disease (CVD). CONCLUSION UCaE correlated with eGFR but it did not affect the change of eGFR over time. Patients with normal UCaE had lower incidence of upper limb fractures and less reduction in BMD. Low UCaE predicted MACE and CVD.

Abstract
Abstract
Introduction/Objective
Granular cell tumors (GCTs) are neoplasms with neuroectodermal (Schwann cell) differentiation that is typically benign and cured by surgical excision. These tumors characteristically display strong expression of S-100 protein. Similar tumors without expression of S-100 protein are called “S-100 negative granular cell tumors.” The few reported cases of S-100 negative GCT in the oral cavity describe indolent clinical behavior. We report a case of a 49-year-old male with recurrent S-100 negative GCT in the oral cavity.
Methods/Case Report
The patient presented initially with a mass in the hard palate, which was resected and diagnosed as an S-100 negative GCT. One year later, the patient developed severe epistaxis and anemia (hemoglobin 7.2 g/dL). A large tumor of the hard palate was the source of bleeding. It was resected and diagnosed as recurrent S-100 negative GCT. Histologically, this tumor consists of small nests of epithelioid to spindled cells with moderately abundant granular eosinophilic cytoplasm, round central nuclei with vesicular chromatin and distinct eosinophilic nucleoli, and significant mitotic activity. The cells are immunoreactive for SOX10 and negative for S-100, melan-A, keratin AE1/AE3, p40, synaptophysin, smooth muscle actin, desmin, and myogenin.
Results (if a Case Study enter NA)
N/A
Conclusion
S-100 negative GCTs are rare, and only a few case reports describe their involvement in the oral cavity. We report this case because of its rarity and aggressive clinical behavior. Recognition of this entity and its potential for locally aggressive growth is important. Management of this tumor by complete excision seems advisable.

Abstract
552 Background: Serum vitamin D levels have been linked to breast cancer development; however, the impact on breast cancer features and outcomes remains unclear. The present study aimed at investigating the prognostic value of baseline vitamin D level among non-metastatic breast cancer patients. Methods: In this study; we prospectively assessed female patients presenting to our department with non-metastatic breast cancer during the period from October 2018 to December 2019 for their baseline serum vitamin D levels measured by ELISA test before starting systemic therapy, in addition to other clinicopathological factors. Low Vit-D was defined as Vit-D level less than 30 ng /l. Chi-square test (Fisher’s exact test) was used to examine the relation between qualitative variables. Survival analysis was done using Kaplan-Meier method and comparison between two survival curves was done using log-rank test. Multivariate analysis was done using Cox-regression hazard model for the significant factors affecting survival on univariate analysis. Results: We enrolled 221 patients with non-metastatic breast cancer as they matched our eligibility criteria. Median age at diagnosis was (50.7± 10.9). About two thirds of the patients (64.7%) were post menopause. Median vitamin D level was (23.1 ng/l) with a range of (4-62.46 ng/liter). Around half of the patients (56.5%) had vitamin D level lower than 30 ng/liter, with higher numbers of low vitamin D levels among HER2 positive and triple negative (TNBC) patients compared to hormonal receptor positive (HR+ve) patients (P=<0.001). There was a significant negative correlation between vitamin D levels and tumor size, lymph node positivity and stage at diagnosis (the lower the vitamin D level, the larger the tumor size, and the higher the number of positive lymph nodes and the stage; r= -0.414, r= -0.586, r= -0.674; respectively; p<0.001). On follow up, the number of local recurrences, bone metastases and liver metastases were significantly higher among the low vitamin D level group, however; there was no significant difference between the two groups in terms of development of brain and lung metastases. Disease free survival (DFS) and overall survival (OS) was significantly worse among the low vitamin D level group (p<0.001). Conclusions: Low serum vitamin D in breast cancer patients negatively correlates with tumor size, lymph node positivity and stage at diagnosis. It is linked to HER-2 positive and TNBC, and is significantly associated with worse DFS and OS.

Abstract
Abstract
Introduction/Objective
Malignant gastrointestinal neuroectodermal tumor (GNET) is a rare soft tissue tumor arising in the wall of the gastrointestinal tract. The GNET was first described as an osteoclast rich tumor of the gastrointestinal tract with features resembling clear cell sarcoma, with only few cases reported in the literature.
Methods/Case Report
We report a case of a 71-year-old man with a past medical history of hypertension, hyperlipidemia, and benign prostatic hyperplasia presented with complaints of dyspnea, dizziness, fatigue, black stools, and a recent syncopal episode. Laboratory testing revealed anemia (HB 5.4 g/dL). Esophagogastroduodenoscopy demonstrated a submucosal gastric mass. An abdominal CT scan confirmed a 7.8 cm mass along the gastric cardia and fundus.
Results (if a Case Study enter NA)
Biopsy rendered a gastrointestinal neuroectodermal tumor (GNET). Microscopically, the tumor cells were spindle with eosinophilic cytoplasm and arranged in fascicules. They were positive for CD56, CD99, and Fli-1, synaptophysin, and negative for chromogranin, TTF-1, SMA, desmin, CD34, EMA, pan-cytokeratin, and lymphoid markers. Two months later, further imaging confirmed metastasis to the liver and spleen. GNETs typically arise within the muscularis propria of the gastrointestinal tract and often extend into the submucosa and subserosa.
Conclusion
The most important differential of GNET is the clear cell sarcoma of the gastrointestinal tract (CCS-GI). Both share similar morphological as well as molecular features and show S100 positivity; however, the lack of melanocytic differentiation in GNET distinguishes it from CCS-GI. Both typically show rearrangements of the EWSR1 gene, with t(12;22) (q13;q12) EWSR1-ATF1 or t(2;22)(q34;q12) EWSR1-CREB1 fusions. Pathologists should be aware of GNET diagnostic entity due to its aggressive behavior and high rate of recurrence and mortality even after complete resection.

Abstract
Breast cancer is one of the most reported cancers that can lead to death. Despite the advances in diagnosis and treatment procedures, the possibility of cancer recurrences is still high in many cases. With that in consideration, researchers from all over the world are showing interest in the unique features of Graphene oxide (GO), such as its excellent and versatile physicochemical properties, to explore further its potential and benefits towards breast cancer cell treatment. In this study, the cell viability and electrical response of GO, in terms of resistivity and impedance towards the breast cancer cells (MCF7) and normal breast cells (MCF10a), were investigated by varying the pH and concentration of GO. Firstly, the numbers of MCF7 and MCF10a were measured after being treated with GO for 24 and 48 h. Next, the electrical responses of these cells were evaluated by using interdigitated gold electrodes (IDEs) that are connected to an LCR meter. Based on the results obtained, as the pH of GO increased from pH 5 to pH 7, the number of viable MCF7 cells decreased while the number of viable MCF10a slightly increased after the incubation period of 48 h. Similarly, the MCF7 also experienced higher cytotoxicity effects when treated with GO concentrations of more than 25 µg/mL. The findings from the electrical characterization of the cells observed that the number of viable cells has corresponded to the impedance of the cells. The electrical impedance of MCF7 decreased as the number of highly insulating viable cell membranes decreased. But in contrast, the electrical impedance of MCF10a increased as the number of highly insulating viable cell membranes increased. Hence, it can be deduced that the GO with higher pH and concentration influence the MCF7 cancer cell line and MCF10a normal breast cell.

Abstract
Abstract
Aim
Preoperative OGD in patients undergoing bariatric surgery, has been a subject for debate for decades. The aim of this study is to evaluate the pathology pick up rate in routine preoperative endoscopy in patients undergoing Gastric Bypass surgery (LRYGB) in our unit.
Method
Retrospective review of patients’ records who underwent LRYBG in our unit from February 2009 to March 2020. Patients were divided into two groups according to the presence or absence of symptoms prior to bariatric surgery: Group A (Asymptomatic) and Group B (Symptomatic). Data from prospectively kept electronic OGD reports, CLO test results, histology reports and the changes in management plan were collected and analysed.
Results
114 patients were included in the analysis, 85 (74.56%) were in group A and 29 in group B. OGD detected pathology in 34 patients in group A and 21 in group B (p = 0.004). Those included hiatus hernia (HH) (17.65% group A, 44.83% group B, p = 0.006); stomach ulcer (7.06% group A, 3.45% group B, p = 0.676), H.pylori infection (12.86% group A, 29.41% group B). This led to change of management in 22 patients in group A and 12 of group B (p = 0.157) excluding PPI prescription. Those changes included H.pylori eradication (10.59% group A, 17.24% group B, p = 0.153), HH repair (3.53% group A, 24.14% group B, p = 0.002). There was no cancellation or change in bariatric surgery offered in both groups.
Conclusions
Preoperative OGD has only significantly impacted the bariatric patient’s pathway in symptomatic patients. However, in Asymptomatic patients, OGD could be replaced by cheaper and non-invasive alternatives.

Abstract
Granulomatosis with polyangiitis formerly known as Wegener's granulomatosis was first described by German pathologist Friedrich Wegener in 1936. It is a multi-system necrotizing noncaseating granulomatous vasculitis which affects small to medium-sized vessels. It can involve any organ system, most commonly the lungs and kidneys. American College of Rheumatology requires 2 of 4 criteria for diagnosis: Positive biopsy for granulomatous vasculitis, urinary sediment with red blood cells, abnormal chest radiograph and oral/nasal inflammation. Here we present a case of Granulomatosis with polyangiitis with brief review of literature.

Molecular Analysis of ZNF71 KRAB in Non-Small-Cell Lung Cancer. Int J Mol Sci 2021; 22:ijms22073752.

Abstract
Our previous study found that zinc finger protein 71 (ZNF71) mRNA expression was associated with chemosensitivity and its protein expression was prognostic of non-small-cell lung cancer (NSCLC). The Krüppel associated box (KRAB) transcriptional repression domain is commonly present in human zinc finger proteins, which are linked to imprinting, silencing of repetitive elements, proliferation, apoptosis, and cancer. This study revealed that ZNF71 KRAB had a significantly higher expression than the ZNF71 KRAB-less isoform in NSCLC tumors (n = 197) and cell lines (n = 117). Patients with higher ZNF71 KRAB expression had a significantly worse survival outcome than patients with lower ZNF71 KRAB expression (log-rank p = 0.04; hazard ratio (HR): 1.686 [1.026, 2.771]), whereas ZNF71 overall and KRAB-less expression levels were not prognostic in the same patient cohort. ZNF71 KRAB expression was associated with epithelial-to-mesenchymal transition (EMT) in both patient tumors and cell lines. ZNF71 KRAB was overexpressed in NSCLC cell lines resistant to docetaxel and paclitaxel treatment compared to chemo-sensitive cell lines, consistent with its association with poor prognosis in patients. Therefore, ZNF71 KRAB isoform is a more effective prognostic factor than ZNF71 overall and KRAB-less expression for NSCLC. Functional analysis using CRISPR-Cas9 and RNA interference (RNAi) screening data indicated that a knockdown/knockout of ZNF71 did not significantly affect NSCLC cell proliferation in vitro.

Abstract
Abstract
Background
Choledocholithiasis (CDL) is a common clinical entity and can lead to serious complications, such as pancreatitis or ascending cholangitis. Endoscopic retrograde cholangio-pancreatography (ERCP) is generally the first-line procedure for definitive management of CDL. ERCP has well-established adverse events. Given the risks, patients can be stratified by likelihood of finding CDL on ERCP, thus potentially avoiding an unnecessary procedure in low probability patients. There are three commonly used criteria for this – the American Society for Gastrointestinal Endoscopy (ASGE) 2010 criteria, the ASGE 2019 criteria, and the European Society of Gastrointestinal Endoscopy (ESGE) 2019 criteria. These criteria use a mixture of biliary imaging, clinical condition, and liver biochemistry to stratify patients into low, intermediate, and high probability for CDL.
Aims
To test the performance characteristics of the ASGE 2010, ASGE 2019, and ESGE 2019 criteria for probability of CDL on a real-world sample.
Methods
We identified all adult patients who had ERCP done at our local centre for suspected CDL between 2012/01/01 and 2018/10/07. A sample of 1000 cases were chosen. We obtained the patients’ pre-procedural liver biochemistries, pre-procedural imaging in the preceding 6 months, and their ERCP reports. We used a semi-automated algorithm to determine confirmation of CDL. We inferred clinical gallstone pancreatitis using the surrogate of serum lipase at or greater than three times upper limit of normal. We could not capture clinical ascending cholangitis from the collected data. We stratified each patient according to the three guidelines and calculated their performance characteristics.
Results
After manually reviewing visits with incomplete ERCP or repeat ERCP, we analyzed 879 ERCP visits. There were 622 with stone or sludge found on ERCP. The performance characteristics of the high-probability and intermediate-probability criteria of the three guidelines are listed in the table below.
Conclusions
Our results for the 2010 ASGE guidelines high probability patients are in keeping with previous validation studies. There have been only one validation study each of the 2019 ASGE guidelines and the 2019 ESGE guidelines, and our results are different in sensitivity and negative predictive value. Future directions in refining these risk stratification tools are needed, and our project in ongoing in assessing the additional value of trends in liver biochemistry.

Abstract
Supply chain operations are disrupted due to natural disasters or epidemics. In the recent period, the supply chain suffers from obstacles and major challenges that affect its stages directly due to the spread of the COVID-19 epidemic around the world. The impact of this epidemic on supply chain performance is clear in terms of supply, demand, or logistics. This epidemic is characterized by a rapid spread, so countries have taken preventive policies in an attempt to limit its spread. These policies are direct impacts on the performance of the supply chain in all scopes. The extent of its impact varies from one supply chain to another, according to the activities that the supply chain provides. In order to provide a more accurate study of the impact of the measures taken to limit the spread of the epidemic, this research presents a proposed framework that evaluates the impact of these policies on the three main aspects of the supply chain (supply, demand, and logistics). The proposed framework is build using BWM and TOPSIS based on plithogenic set. Plithogenic set provides a more accurate evaluation result that addresses the uncertainty problem. Supply chain aspects were evaluated for the food industry, electronics industry, pharmaceutical industry, and textile industry.

Abstract
The rapid spread of the COVID-19 virus around the world poses a real threat to public safety. Some COVID-19 symptoms are similar to other viral chest diseases, which makes it challenging to develop models for effective detection of COVID-19 infection. This article advocates a model to differentiate between COVID-19 and other four viral chest diseases under uncertainty environment using the viruses primary symptoms and CT scans. The proposed model is based on a plithogenic set, which provides higher accurate evaluation results in an uncertain environment. The proposed model employs the best-worst method (BWM) and the technique in order of preference by similarity to ideal solution (TOPSIS). Besides, this study discusses how smart Internet of Things technology can assist medical staff in monitoring the spread of COVID-19. Experimental evaluation of the proposed model was conducted on five different chest diseases. Evaluation results demonstrate that the proposed model effectiveness in detecting the COVID-19 in all five cases achieving detection accuracy of up to 98%.

Abstract
Abstract
Background
Previous studies have demonstrated that many graduating trainees may not have all of the skills needed to independently practice endoscopic retrograde cholangiopancreatography (ERCP) safely and effectively. As a part of competency-based learning curriculum development, it is essential to provide formative feedback to trainees and ensure they acquire the knowledge and skills for independent practice.
Aims
To assess the performance of advanced endoscopy trainees across Canada using the Canadian Direct Observation of Procedural Skills (CanDOPS) ERCP assessment tool. Procedural items evaluated include both technical (cannulation, sphincterotomy, stone extraction, tissue sampling, and stent placement) and non-technical (leadership, communication and teamwork, judgment and decision making) skills.
Methods
We conducted a prospective national multi-centre prospective study. Advanced endoscopy trainees with at least two years of gastroenterology training or five years of general surgery in North America and minimal experience performing ERCPs (less than 100 ERCP procedures) were invited to participate. The CanDOPS tool was used to measure every fifth ERCP performed by trainees over a 12-month fellowship training period. ERCPs were evaluated by experienced staff endoscopists at each study site under standard clinical protocol. Cumulative sum (CUSUM) analyses were used to generate learning curves.
Results
The data from five Canadian sites and 11 trainees participated in the study. A total of 261ERCP evaluations were completed. Median number of evaluations by site and trainee was 49 (IQR 31–76) and 15 (IQR 11–45). Median number of cases trainees performed prior to their ERCP training was 50 (IQR 25–400). There was a significant improvement in almost all scores over time, including selective cannulation, sphincterotomy, biliary stenting and all non-technical skills (P<0.01). CUSUM analyses using acceptable and unacceptable failure rates of 20% and 50% demonstrated trainees achieved competency for most measures in their final month of their training. Competency in tissue sampling was not achieved within a one-year training period.
Conclusions
This is the first ERCP performance evaluation tool that examines multiple technical and non-technical aspects of the procedure. Although trainee ERCP skills do improve during their training period, there exists a notable variability in time to competency for the different skills measured using the CanDOPS tool. Large prospective research is required to determine if competency is achieved using more stringent definitions of ERCP competency and to determine factors associated with reaching competency.

Abstract
Abstract
Background
Endoscopic ultrasound-guided biliary drainage (EUS-BD) is a promising alternative to endoscopic retrograde cholangiopancreatography (ERCP) in malignant distal biliary obstruction (MDBO). Recent small randomized controlled trials comparing EUS-BD with ERCP suggest that EUS-BD achieves a similar technical success rate and safety profile while potentially being associated with lower rates of stent dysfunction However, its application in clinical practice has been impeded by various undefined barriers.
Aims
To evaluate the current practice of EUS-BD and the determinants for its clinical implementation in MDBO.
Methods
An online survey was generated using Google Forms. Five endoscopy societies have distributed the survey as of October 10th, 2019. Survey questions measured participant characteristics, EUS-BD in different clinical scenarios, and potential barriers to implementation. Descriptive statistics were calculated using frequencies, chi-square statistics were used for inferential analysis, and a standard step-wise multivariable analysis was performed to identify independent variables for and against the use of EUS-BD.
Results
To date, 102 physicians have participated in the survey (response rate 7.97%). The majority of participants are from North America (39.2%), Asia (31.4%), and Europe (19.6%). Most participants are gastroenterologists with formal therapeutic endoscopy training (66.7%), though only 28.4% have received EUS-BD training. In unresectable cancer, 85.1% of respondents favoured EUS-BD over percutaneous biliary drainage following ERCP failure (p<0.0001), while in borderline resectable disease, 72.3% preferred EUS-BD. On multivariable analysis, male gender, formal training in EUS-BD, and unresectable cancer were independent variables for the use of EUS-BD. Conversely, independent discouraging factors for EUS-BD included fear of adverse events, limited high-quality data, lack of local expertise, and inadequate access to EUS technology.
Conclusions
In this international survey, it appears that EUS-BD is gaining traction, especially in the setting of unresectable disease following ERCP failure. However, barriers to implementation include the lack of high-quality data, fear for adverse events, limited experts in the field, and inadequate access to EUS technology. This suggest the need for high-quality clinical trials, increased endoscopist training in this field, and further technology development in EUS-BD in order to increase its uptake in clinical practice.

Detection of Crimean-Congo Haemorrhagic Fever cases in a severe undifferentiated febrile illness outbreak in the Federal Republic of Sudan: A retrospective epidemiological and diagnostic cohort study. PLoS Negl Trop Dis 2019; 13:e0007571. [PMID: 31291242 PMCID: PMC6645580 DOI: 10.1371/journal.pntd.0007571] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/25/2019] [Revised: 07/22/2019] [Accepted: 06/22/2019] [Indexed: 01/12/2023] Open
Abstract
Background Undifferentiated febrile illness (UFI) is one of the most common reasons for people seeking healthcare in low-income countries. While illness and death due to specific infections such as malaria are often well-quantified, others are frequently uncounted and their impact underappreciated. A number of high consequence infectious diseases, including Ebola virus, are endemic or epidemic in the Federal Republic of Sudan which has experienced at least 12 UFI outbreaks, frequently associated with haemorrhage and high case fatality rates (CFR), since 2012. One of these occurred in Darfur in 2015/2016 with 594 cases and 108 deaths (CFR 18.2%). The aetiology of these outbreaks remains unknown. Methodology/Principal findings We report a retrospective cohort study of the 2015/2016 Darfur outbreak, using a subset of 65 of 263 outbreak samples received by the National Public Health Laboratory which met selection criteria of sufficient sample volume and epidemiological data. Clinical features included fever (95.8%), bleeding (95.7%), headache (51.6%) and arthralgia (42.2%). No epidemiological patterns indicative of person-to-person transmission or health-worker cases were reported. Samples were tested at the Public Health England Rare and Imported Pathogens Laboratory using a bespoke panel of likely pathogens including haemorrhagic fever viruses, arboviruses and Rickettsia, Leptospira and Borrelia spp. Seven (11%) were positive for Crimean-Congo haemorrhagic fever virus (CCHFV) by real-time reverse transcription PCR. The remaining samples tested negative on all assays. Conclusions/Significance CCHFV is an important cause of fever and haemorrhage in Darfur, but not the sole major source of UFI outbreaks in Sudan. Prospective studies are needed to explore other aetiologies, including novel pathogens. The presence of CCHFV has critical infection, prevention and control as well as clinical implications for future response. Our study reinforces the need to boost surveillance, lab and investigative capacity to underpin effective response, and for local and international health security. The Federal Republic of Sudan has had at least 12 outbreaks of febrile illness of unknown cause associated with symptoms of haemorrhage and high case fatality rates since 2012. Outbreaks without clear diagnosis are concerning, particularly in countries such as Sudan where a range of high consequence diseases, including viral haemorrhagic fevers, are endemic or epidemic, and local laboratory capacity is limited. We transferred historical samples stored in the National Public Health Authority from one of these outbreaks that occurred in Darfur 2015–2016 to the Public Health England Laboratory at Porton, UK, and tested them against a wide range of infectious diseases to try to identify the cause, and to help the Sudanese Federal Ministry of Health to develop and target their limited laboratory capacity. We found that Crimean-Congo Haemorrhagic Fever was an important cause but not the only source of cases in this outbreak. This has implications for prevention and control as well as for treating cases. Our study also highlighted the need for future studies to explore other possible causes, including new pathogens, and reinforced the need to boost surveillance, lab and investigative capacity for more timely and complete outbreak response.

Abstract
Due to the introduction of newer, more efficacious treatment options, there is a pressing need for policy makers and public health officials to develop or adapt national hepatitis C virus (HCV) control strategies to the changing epidemiological landscape. To do so, detailed, country-specific data are needed to characterize the burden of chronic HCV infection. In this study of 17 countries, a literature review of published and unpublished data on HCV prevalence, viraemia, genotype, age and gender distribution, liver transplants and diagnosis and treatment rates was conducted, and inputs were validated by expert consensus in each country. Viraemic prevalence in this study ranged from 0.2% in Hong Kong to 2.4% in Taiwan, while the largest viraemic populations were in Nigeria (2 597 000 cases) and Taiwan (569 000 cases). Diagnosis, treatment and liver transplant rates varied widely across the countries included in this analysis, as did the availability of reliable data. Addressing data gaps will be critical for the development of future strategies to manage and minimize the disease burden of hepatitis C.

Abstract
Factors influencing the morbidity and mortality associated with viremic hepatitis C virus (HCV) infection change over time and place, making it difficult to compare reported estimates. Models were developed for 17 countries (Bahrain, Bulgaria, Cameroon, Colombia, Croatia, Dominican Republic, Ethiopia, Ghana, Hong Kong, Jordan, Kazakhstan, Malaysia, Morocco, Nigeria, Qatar and Taiwan) to quantify and characterize the viremic population as well as forecast the changes in the infected population and the corresponding disease burden from 2015 to 2030. Model inputs were agreed upon through expert consensus, and a standardized methodology was followed to allow for comparison across countries. The viremic prevalence is expected to remain constant or decline in all but four countries (Ethiopia, Ghana, Jordan and Oman); however, HCV-related morbidity and mortality will increase in all countries except Qatar and Taiwan. In Qatar, the high-treatment rate will contribute to a reduction in total cases and HCV-related morbidity by 2030. In the remaining countries, however, the current treatment paradigm will be insufficient to achieve large reductions in HCV-related morbidity and mortality.

Abstract
The hepatitis C virus (HCV) epidemic was forecasted through 2030 for 17 countries in Africa, Asia, Europe, Latin America and the Middle East, and interventions for achieving the Global Health Sector Strategy on viral hepatitis targets-"WHO Targets" (65% reduction in HCV-related deaths, 90% reduction in new infections and 90% of infections diagnosed by 2030) were considered. Scaling up treatment and diagnosis rates over time would be required to achieve these targets in all but one country, even with the introduction of high SVR therapies. The scenarios developed to achieve the WHO Targets in all countries studied assumed the implementation of national policies to prevent new infections and to diagnose current infections through screening.

Abstract
Worldwide, some 240 million people have chronic hepatitis B virus (HBV), with the highest rates of infection in Africa and Asia. Our understanding of the natural history of HBV infection and the potential for therapy of the resultant disease is continuously improving. New data have become available since the previous APASL guidelines for management of HBV infection were published in 2012. The objective of this manuscript is to update the recommendations for the optimal management of chronic HBV infection. The 2015 guidelines were developed by a panel of Asian experts chosen by the APASL. The clinical practice guidelines are based on evidence from existing publications or, if evidence was unavailable, on the experts' personal experience and opinion after deliberations. Manuscripts and abstracts of important meetings published through January 2015 have been evaluated. This guideline covers the full spectrum of care of patients infected with hepatitis B, including new terminology, natural history, screening, vaccination, counseling, diagnosis, assessment of the stage of liver disease, the indications, timing, choice and duration of single or combination of antiviral drugs, screening for HCC, management in special situations like childhood, pregnancy, coinfections, renal impairment and pre- and post-liver transplant, and policy guidelines. However, areas of uncertainty still exist, and clinicians, patients, and public health authorities must therefore continue to make choices on the basis of the evolving evidence. The final clinical practice guidelines and recommendations are presented here, along with the relevant background information.

Abstract
Increased susceptibility of diabetics to melioidosis, a disease caused by the Burkholderia pseudomallei bacterium is believed to be attributed to dysfunction of the innate immune system. However, the underlying mechanism of the innate susceptibility is not well-understood. Glycogen synthase kinase-3β (GSK3β) plays an important role in the innate inflammatory response caused by bacterial pathogens. The present study was conducted to investigate the effects of GSK3β inhibition by LiCl on levels of pro- and anti-inflammatory cytokines; and the activity of transcription factor NF-κB in B. pseudomallei-infected peripheral blood mononuclear cells (PBMC) derived from diabetic-induced and normal Sprague Dawley rats. In addition, the effects of LiCl on intracellular bacterial counts were also investigated. Infection of PBMC from diabetic and normal rats with B. pseudomallei resulted in elevated levels of cytokines (TNF-α, IL-12 and IL-10) and phosphorylation of NF-κB in both cell types. Intracellular bacterial counts decreased with time in both cell types during infection. However bacterial clearance was less prominent in diabetic PBMC. Burkholderia pseudomallei infection also caused inactivation (Ser9 phosphorylation) of GSK3β in normal PBMC, an effect absent in infected diabetic PBMC. Inhibition of GSK3β by LiCl lowered the levels of pro-inflammatory cytokines (TNF-α and IL-12) in both normal and diabetic PBMC. Similarly, phosphorylated NF- κB (pNF-κB) levels in both cell types were decreased with LiCl treatment. Also, LiCl was able to significantly decrease the intracellular bacterial count in normal as well as diabetic PBMC. Interestingly, the levels of anti-inflammatory cytokine IL-10 in both normal and diabetic PBMC were further elevated with GSK3β inhibition. More importantly, GSK3β in infected diabetic PBMC was inactivated as in their non-diabetic counterparts upon LiCl treatment. Taken together, our results suggest that inhibition of dysregulated GSK3β in diabetic PBMC resulted in the inactivation of NF-κB and modulation of inflammatory cytokine levels. This is evidence that dysregulation of GSK3β is a contributing factor in the molecular basis of innate dysfunction and susceptibility of diabetic host to melioidosis infection.

Abstract
UNLABELLED We aimed to evaluate long-term treatment outcomes and toxicity profile of postoperative radiotherapy (PORT) in Saudi women with uterine cancers. METHODS AND MATERIALS Medical records of patients with histopathologically proven uterine cancers were reviewed and identified those who received PORT (45-50.4 Gy in 25-28 fractions) followed by vaginal brachytherapy (15-20 Gy in 3 to 4 sessions) after total abdominal hystrectomy and bilateral salpingo-oophorectomy (TAHBSO) in our center between August 2007 and April 2012. Data regarding the safety profile, locoregional control (LRC) or distant metastases control (DMC) and overall survival (OS) rates were analyzed. RESULTS Median follow-up period was 60 months (range, 12-70) for 89 patients. Predominant histological type was endometrial (59 patients), followed by carcinosarcoma (17 patients) and leiomyosarcoma (13 patients). Median age at time of diagnosis was 57.6, 56 and 51.1 years for endometrial, carcinosarcoma and leiomyosarcoma respectively. LRC rates were 80.9%, 87.1% and 100% for leiomyosarcoma, carcinosarcoma and endometrial carcinoma respectively (p 0.4). DMC rates were 69.3%, 45% and 16.3% for endometrial, leiomyosarcoma and carcinosarcoma respectively (p 0.0001). Five-year OS rates were 71.1%, 60% and 16.3% for endometrial, leiomyosarcoma and carcinosarcoma respectively (p 0.001). Coxproportional hazard ratio model showed body mass index, FIGO stage, lymphovascular invasion in endometrial carcinoma, tumor size in leiomyosarcoma and histology in carcinosarcoma important prognostic factors for LRC. Acute grade 3 and 4 proctitis/enteritis seen only in 4 patients (4.5%) and late toxicities were minimal. CONCLUSION PORT in Saudi women with uterine cancers showed better LRC, DMC and OS rates with minimal toxicity.

Abstract
A novel low temperature crystallization process called eutectic freeze crystallization (EFC) can produce both salt(s) and ice from a reverse osmosis (RO) stream by operating at the eutectic temperature of a solution. The EFC reject stream, which is de-supersaturated with respect to the scaling component, can subsequently be recycled back to the RO process for increased water recovery. This paper looks at the feasibility of using EFC to remove calcium sulfate from an RO retentate stream and compares the results to recovery rates at 0 and 20 °C. The results showed that there was a greater yield of calcium sulfate obtained at 0 °C as compared with 20 °C. Operation under eutectic conditions, with only a 20% ice recovery, resulted in an even greater yield of calcium sulfate (48%) when compared with yields obtained at operating temperatures of 0 and 20 °C (15% at 0 °C and 13% at 20 °C). The theoretical calcium recoveries were found to be 75 and 70% at 0 and 20 °C respectively which was higher than the experimentally determined values. The EFC process has the added advantage of producing water along with a salt.

Abstract
An all-optical generation of a microwave carrier at 21 GHz that incorporates a double-Brillouin frequency shifter is presented. The frequency shift of approximately 21 GHz is achieved by generating the second-order Brillouin Stokes signal from the Brillouin pump. This is accomplished through the circulation and isolation of its first-order Stokes signal in the optical fiber. The Brillouin pump signal is heterodyned with its second-order Brillouin Stokes signal at a high-speed photodetector, and the output beating frequency is equal to the offset between these two signals. The generated microwave carrier is measured at 21.3968 GHz, and the carrier phase noise as low as -58.67 dBc/Hz is achieved.
