Abstract
Background
The use of high-throughput analytical techniques has enabled the description of acute lymphoblastic leukaemia (ALL) subtypes. The TCF3-HLF translocation is a very rare rearrangement in ALL that is associated with an extremely poor prognosis. The TCF3-HLF fusion gene in the described case resulted in the fusion of the homeobox-related gene of TCF3 to the leucine zipper domain of HLF. The TCF3-HLF fusion gene product acts as a transcriptional factor leading to the dedifferentiation of mature B lymphocytes into an immature state (lymphoid stem cells). This process initiates the formation of pre-leukaemic cells. Due to the rarity of this chromosomal aberration, only a few cases have been described in the literature. The advantage of this work is the presentation of an interesting case of clonal evolution of cancer cells and the cumulative implications (diagnostic and prognostic) of the patient’s genetic alterations.

Case presentation
This work presents a patient with diagnosed with TCF3-HLF-positive ALL. Moreover, the additional genetic alterations, which play a key role in the pathogenesis of ALL, were detected in this patient: deletion of a fragment from the long arm of chromosome 13 (13q12.2-q21.1) containing the RB1 gene, intragenic deletions within the PAX5 gene and NOTCH1 intragenic duplication.

Conclusions
A patient with coexistence of chromosomal alterations and the TCF3-HLF fusion has not yet been described. Identifying all these chromosomal aberrations at the time of diagnosis could be sufficient to determine the cumulative effects of the described deletions on the activity of other oncogenes or tumour suppressors, as well as on the clinical course of the disease. On the other hand, complex changes in the patient’s karyotype and clonal evolution of cancer cells call into question the effectiveness of experimental therapy.

Abstract
Background
Newly identified lncRNA zinc finger protein, FOG family member 2 antisense RNA 1 (ZFPM2-AS1) is identified as an oncogenic gene. However, the role of ZFPM2-AS1 in small cell lung cancer (SCLC) is poorly comprehended.

Methods
The expression of genes in SCLC tissues and cells was measured by qRT-PCR. Colony formation, EdU, CCK-8, transwell and wound healing as well as in vivo assays revealed the function of ZFPM2-AS1 in SCLC. ChIP, luciferase reporter, RIP and RNA pull down assays demonstrated the binding relation among genes.

Results
ZFPM2-AS1 was significantly upregulated in SCLC tissues and cells. ZFPM2-AS1 deficiency attenuated SCLC cell proliferation, invasion and migration. In addition, ZFPM2-AS1 was transcriptionally activated by Yin Yang 1 (YY1) factor. Further, miR-3612 was confirmed as downstream miRNA of ZFPM2-AS1. Moreover, TNF receptor associated factor 4 (TRAF4) was the target gene of miR-3612 in SCLC. ZFPM2-AS1, miR-3612 and TRAF4 jointly constituted a competing endogenous RNA (ceRNA) network in SCLC. Finally, TRAF4 could countervail ZFPM2-AS1 downregulation-mediated function on SCLC cell proliferation and invasion in vitro and tumor growth in vivo.

Conclusion
Our study elucidated the oncogenic effect of ZFPM2-AS1 in SCLC progression, indicating it may be a therapeutic target for SCLC.
Diet and nutrient status of legume consumers in Sweden: a descriptive cross-sectional study
Authors: Steib Céline A. , Johansson Ingegerd , Hefni Mohammed E. , Witthöft Cornelia M. 
Published: April 2020

AbstractBackgroundLegumes are nutrient-dense foods and can be an environmentally sustainable alternative to meat consumption. Data on legume intake are scarce and data on legume consumption in Sweden are lacking. This study investigated dietary intake and dietary patterns, together with iron, vitamin D, and folate status, in relation to legume consumption in Sweden.MethodsCross-sectional dietary and biomarker data (n 1760) from the 2011 Riksmaten national survey were analyzed. All legume foods (including soy) were identified from 4-day dietary records and ferritin, folate, and vitamin D status in a subgroup (n 280). Participants were classified into non-consumers and quartiles of legume intake. Principal Component Analysis (PCA) was performed to uncover dietary patterns associated with legume intake. Partial Least Square (PLS) regression was used to identify variables associated with variations in legume consumption.ResultsLegumes were consumed by 44% of the population, with mean (SD) intake of 138 (84) g/d in the highest and 11 (5) g/d in the lowest quartiles. Among consumers, 6% reported being vegetarian, compared with 0.9% among non-consumers. Legume consumers drank less alcohol, but had higher intakes of energy, dietary fiber, folate, thiamin, and several minerals, and more often met recommended intake levels for folate and fiber, critical nutrients in Sweden. Biomarker status did not differ with legume intake. PCA revealed multiple loadings on legumes that generally reflected healthier eating habits for legume-consuming women. PLS revealed that vegetarianism was most influential for high legume intake. Other influential variables were high fruit, tea, nut, and seed intakes. High intake of meat, sodas, fast foods, and sweet foods, together with omnivorism, were influential for low legume intake. The associations were similar for men and women.ConclusionsThis study supports dietary recommendations on inclusion of legumes in a healthy diet. Greater focus on assessment of legume intake is necessary to explore the population-wide health effects of legumes as sustainable meat alternatives, and to reinforce national nutritional guidelines.

Abstract
Background
Malaysia has the highest rate of diabetes mellitus (DM) in the Southeast Asian region, and has ongoing air pollution and periodic haze exposure.

Methods
Diabetes data were derived from the Malaysian National Health and Morbidity Surveys conducted in 2006, 2011 and 2015. The air pollution data (NOx, NO2, SO2, O3 and PM10) were obtained from the Department of Environment Malaysia. Using multiple logistic and linear regression models, the association between long-term exposure to these pollutants and prevalence of diabetes among Malaysian adults was evaluated.

Results
The PM10 concentration decreased from 2006 to 2014, followed by an increase in 2015. Levels of NOx decreased while O3 increased annually. The air pollutant levels based on individual modelled air pollution exposure as measured by the nearest monitoring station were higher than the annual averages of the five pollutants present in the ambient air. The prevalence of overall diabetes increased from 11.4% in 2006 to 21.2% in 2015. The prevalence of known diabetes, underdiagnosed diabetes, overweight and obesity also increased over these years. There were significant positive effect estimates of known diabetes at 1.125 (95% CI, 1.042, 1.213) for PM10, 1.553 (95% CI, 1.328, 1.816) for O3, 1.271 (95% CI, 1.088, 1.486) for SO2, 1.124 (95% CI, 1.048, 1.207) for NO2, and 1.087 (95% CI, 1.024, 1.153) for NOx for NHMS 2006. The adjusted annual average levels of PM10 [1.187 (95% CI, 1.088, 1.294)], O3 [1.701 (95% CI, 1.387, 2.086)], NO2 [1.120 (95% CI, 1.026, 1.222)] and NOx [1.110 (95% CI, 1.028, 1.199)] increased significantly from NHMS 2006 to NHMS 2011 for overall diabetes. This was followed by a significant decreasing trend from NHMS 2011 to 2015 [0.911 for NO2, and 0.910 for NOx].

Conclusion
The findings of this study suggest that long-term exposure to O3 is an important associated factor of underdiagnosed DM risk in Malaysia. PM10, NO2 and NOx may have mixed effect estimates towards the risk of DM, and their roles should be further investigated with other interaction models. Policy and intervention measures should be taken to reduce air pollution in Malaysia.

Abstract
Backgrounds
Intolerable toxicity and unsatisfactory therapeutic effects are still big problems retarding the use of chemotherapy against cancer. Nano-drug delivery system promised a lot in increasing the patients’ compliance and therapeutic efficacy. As a unique nano-carrier, supermolecular aggregation nanovehicle has attracted increasing interests due to the following advantages: announcing drug loading efficacy, pronouncing in vivo performance and simplified production process.

Methods
In this study, the supermolecular aggregation nanovehicle of bortezomib (BTZ) was prepared to treat breast cancer.

Results
Although many supermolecular nanovehicles are inclined to disintegrate due to the weak intermolecular interactions among the components, the BTZ supermolecules are satisfying stable. To shed light on the reasons behind this, the forces driving the formation of the nanovehicles were detailed investigated. In other words, the interactions among BTZ and other two components were studied to characterize the nanovehicles and ensure its stability.

Conclusions
Due to the promising tumor targeting ability of the BTZ nanovehicles, the supermolecule displayed promising tumor curing effects and negligible systemic toxicity.

Abstract
Introduction
The impact of advanced laryngeal cancer and its extensive surgical treatments cause significant morbidity for these patients. Total laryngectomy impacts essential functions such as breathing, communication and swallowing, and may influence the quality of life as well as affecting the social life of laryngeal cancer patients.

Objective
Describe the quality of life and analyze the factors associated with the reduced quality of life in patients who have undergone total laryngectomy.

Method
Observational cross-sectional study was carried out to evaluate the quality of life of patients who had undergone total laryngectomy due to laryngeal cancer. The fourth version of the UW-QOL Quality of Life Assessment Questionnaire from Washington University, validated for Portuguese, was used.

Results
The study population was 95 patients, and the mean composite score of the QOL was 80.4. In the subjective domains the majority of the patients (38.9%) reported they felt much better at present compared to the month before being diagnosed with cancer. When questioned about how they evaluated their health-related quality of life, there was a predominance of those who considered it good (43.2%), and most considered they had a good quality of life (46.3%) considering personal well-being. The overall quality of life was considered good to excellent by 83.2% of the patients. Patients with tracheoesophageal prosthesis reported a better quality of life, compared to patients using an electrolarynx or esophageal voice.

Conclusion
The high mean value of the composite score for quality of life revealed that the patients assessed their quality of life positively. The absence of vocal emission was the only variable associated with a lower quality of life within the composite score according to the UW-QOL questionnaire.

Published: April 2020

Abstract
Background
As advances in oncological treatment continue to prolong the survival of patients with non-resectable pancreatic ductal adenocarcinoma (PDAC), decision-making regarding palliative surgical bypass in patients with a heavy disease burden turns challenging. Here we present the results of a pancreatic surgery referral center.

Methods
Patients that underwent palliative gastrojejunostomy and/or hepaticojejunostomy for advanced, non-resectable PDAC between January 2010 and November 2018 were retrospectively assessed. All patients were taken to a purely palliative surgery with no curative intent. The postoperative course as well as short and long-term outcomes was evaluated in relation to preoperative parameters.

Results
Forty-two patients (19 females) underwent palliative bypass. Thirty-one underwent only gastrojejunostomy (22 laparoscopic) and 11 underwent both gastrojejunostomy and hepaticojejunostomy (all by an open approach). Although 34 patients (80.9%) were able to return temporarily to oral intake during the index admission, 15 (35.7%) suffered from a major postoperative complication. Seven patients (16.6%) died from surgery and another seven within the following month. Nine patients (21.4%) never left the hospital following the surgery. Mean length of hospital stay was 18 ± 17 days (range 3–88 days). Mean overall survival was 172.8 ± 179.2 and median survival was 94.5 days. Age, preoperative hypoalbuminemia, sarcopenia, and disseminated disease were associated with palliation failure, defined as inability to regain oral intake, leave the hospital, or early mortality.

Conclusions
Although palliative gastrojejunostomy and hepaticojejunostomy may be beneficial for specific patients, severe postoperative morbidity and high mortality rates are still common. Patient selection remains crucial for achieving acceptable outcomes.
“Children are a blessing from God” – a qualitative study exploring the socio-cultural factors influencing contraceptive use in two Muslim communities in Kenya

Published: April 2020

Abstract
Background
Family planning (FP) is one of the high impact public health interventions with huge potential to enhance the health and wellbeing of women and children. Yet, despite the steady progress made towards expanding access to family planning, major disparities across different regions exist in Kenya. This study explored the socio cultural factors influencing FP use among two Muslim communities in Kenya.

Methods
A qualitative study involving Focus Group Discussions (FGDs) and In-depth Interviews (IDIs) was conducted (from July to October 2018) in two predominant Muslim communities of Lamu and Wajir counties. Open ended questions explore key thematic areas around knowledge, attitudes and understanding of contraception, perceived FP barriers, and decision making for contraceptives, views on Islam and contraception, and fertility preference. All interviews were conducted in the local language, recorded, transcribed verbatim and translated into English. Data was analyzed using thematic content analyses.

Results
Although Islam is the predominant religion the two communities, perceptions and belief around FP use were varied. There were differing interpretations of Islamic teaching and counter arguments on whether or not Islam allows FP use. This, in addition to desire for a large family, polygamy, high child mortality and a cultural preference for boys had a negative impact on FP use. Similarly, inability of women to make decisions on their reproductive health was a factor influencing uptake of FP.

Conclusion
Misinterpretation of Islamic teaching on contraception likely influences uptake of family planning. Cultural beliefs and lack of women’s decision power on fertility preferences were a key inhibitor to FP use. Countering the negative notions of FP use requires active engagement of religious leaders and Muslim scholars who are in position of power and influence at community level.

AbstractBackgroundPorcine epidemic diarrhea virus (PEDV) infection causes an acute enteric tract infectious disease characterized by vomiting, anorexia, dehydration, weight loss and high mortality in neonatal piglets. During PEDV infection, the spike protein (S) is a major virion structural protein interacting with receptors and inducing neutralizing antibodies. However, the neutralizing B-cell epitopes within PEDV S protein have not been well studied.MethodsTo accurately identify the important immunodominant region of S1, the purified truncated S1 proteins (SA, SB, SC, SD and SE) were used to immunize BALB/c mice to prepare polyclonal antibodies. The antisera titers were determined by indirect ELISA, western blot and IFA after four immunizations to find the important immunodominant region of S1, and then purified the immunodominant region of S1 protein and immunized mice to generate the special antibodies, and then used recombinant peptides to determine the B-cell epitopes of monoclonal antibodies.ResultsFive antisera of recombinant proteins of the spike protein region of PEDV were generated and we found that only the polyclonal antibody against part of the S1 region (signed as SE protein, residues 666–789) could recognize the native PEDV. Purified SE protein was used to immunize BALB/c mice and generate mAb 2E10. Pepscan of the SE protein demonstrated that SE16 (722SSTFNSTREL731) is the minimal linear epitope required for reactivity with the mAb 2E10. Further investigation indicated that the epitope SE16 was localized on the surface of PEDV S protein in the 3D structure.ConclusionsA mAb 2E10 that is specifically bound to PEDV was generated and identified a specific linear B-cell epitope (SE16,722SSTFNSTREL731) of the mAb. The epitope region of PEDV S1 localized in the different regions in comparison with the earlier identified epitopes. These findings enhance the understanding of the PEDV spike protein structure for vaccine design and provide a potential use for developing diagnostic methods to detect PEDV.

Abstract
Background
Low back pain is a common condition among older adults that significantly influences physical function and participation. Compared to their younger counterparts, there is limited information available about the clinical course of low back pain in older people, in particularly those presenting for chiropractic care. Improving our understanding of this patient population and the course of their low back pain may provide input for studies researching safer and more effective care than is currently provided.

Objectives
The primary objectives are to examine the clinical course over one year of pain intensity, healthcare costs and pain, functional status and recovery rates of low back pain in people 55 years and older who visit a chiropractor for a new episode of low back pain.

Methods
An international prospective, multi-center cohort study with one-year follow-up. Chiropractic practices are to be recruited in the Netherlands, Sweden, United Kingdom and Australia. Treatment will be left to the discretion of the chiropractor. Inclusion/Exclusion criteria: Patients aged 55 and older who consult a chiropractor for a new episode of low back pain, meaning low back pain for the first time or those patients who have not been to a chiropractor in the previous six months. This is independent of whether they have seen another type of health care provider for the current episode. Patients who are unable to complete the web-based questionnaires because of language restrictions or those with computer literacy restrictions will be excluded as well as those with cognitive disorders. In addition, those with a suspected tumor, fracture, infection or any other potential red flag or condition considered to be a contraindication for chiropractic care will be excluded. Data will be collected using online questionnaires at baseline, and at 2 and 6 weeks and at 3, 6, 9 and 12 months.

Discussion
This study, to our knowledge, is the first large-scale, prospective, multicenter, international cohort study to be conducted in a chiropractic setting to focus on older adults with low back pain consulting a chiropractor. By understanding the clinical course, satisfaction and safety of chiropractic treatment of this common debilitating condition in the aged population, this study will provide input for informing future clinical trials.

Published: April 2020

AbstractBackgroundSeveral studies reported that history of alcohol use among prisoners is higher than the prevalence in the general population. Criminality is found to be associated with alcohol use disorder (AUD) in previous studies. In Ethiopia, there is limited information on the prevalence and associated factors of AUD among prisoners. Therefore, this study aimed to assess the prevalence and associated factors of AUD among prisoners of Debre Berhan Prison.MethodsA cross-sectional survey was conducted to assess history of AUD among prisoners at Debre Berhan Prison, before imprisonment. We selected 347 prisoners with a systematic sampling technique and interviewed using Alcohol Use Disorder Identification Test (AUDIT) to screen for AUD in May 2017. Data entry was done using Epi-Data version 3.1 software, and bivariate and multivariate analyses were done using Stata version 13 software. Crude and adjusted odds ratios, with 95% confidence intervals andp-values are reported.ResultsAbout six out of ten prisoners (59.1%) had AUD before imprisonment. Factors associated with increased odds of AUD were perception that the current offence is related to using substances (AOR = 4.2; 95% CI = 2.3, 7.8), and family history of substance use (AOR = 8.7; 95% CI = 1.7, 44.9). Being married had lower odds of AUD compared to the unmarried (AOR = 0.5; 95% CI = 0.2, 0.9).ConclusionWe found that the prevalence of AUD 1 year before imprisonment in this population is high. AUD is found to be associated with a family history of substance use and perception that the current offence is related to using a substance. We recommend community-based study with different kind of study designs to see the relationship between AUD and crime for planning interventions.
