Abstract
Chronic myeloid leukemia (CML) is a clonal hematopoietic stem cell disorder resulting from a balanced translocation leading to BCR::ABL1 oncogene with increased tyrosine kinase activity. Despite the advancements in the development of tyrosine kinase inhibitors (TKIs), the T315I gatekeeper point mutation in the BCR::ABL1 gene remains a challenge. We have previously reported in a Drosophila CML model an increased hemocyte count and disruption in sessile hemocyte patterns upon expression of BCR::ABL1p210 and BCR::ABL1T315I in the hemolymph. In this study, we performed RNA sequencing to determine if there is a distinct gene expression that distinguishes BCR::ABL1p210 and BCR::ABL1T315I. We identified six genes that were consistently upregulated in the fly CML model and validated in adult and pediatric CML patients and in a mouse cell line expressing BCR::ABL1T315I. This study provides a comprehensive analysis of gene signatures in BCR::ABL1p210 and BCR::ABL1T315I, laying the groundwork for targeted investigations into the role of these genes in CML pathogenesis.

Abstract
Colorectal cancer (CRC) is one of the most common cancer types, ranking third after lung and breast cancers. As such, it demands special attention for better characterization, which may eventually result in the development of early detection strategies and preventive measures. Currently, components of bodily fluids, which may reflect various disease states, are being increasingly researched for their biomarker potential. One of these components is the circulating extracellular vesicles, namely, exosomes, which are demonstrated to carry various cargo. Of importance, the non-coding RNA cargo of circulating exosomes, especially long non-coding RNAs (lncRNAs), circular RNAs (circRNAs), and micro RNAs (miRNAs), may potentially serve as significant diagnostic and prognostic/predictive biomarkers. In this review, we present existing evidence on the diagnostic and prognostic/predictive biomarker value of exosomal non-coding RNAs in CRC. In addition, taking advantage of the miRNA sponging functionality of lncRNAs and circRNAs, we demonstrate an experimentally validated CRC exosomal non-coding RNA-regulated target gene axis benefiting from published miRNA sponging studies in CRC. Hence, we present a set of target genes and pathways downstream of the lncRNA/circRNA–miRNA–target axis along with associated significant Gene Ontology (GO) terms and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathways, which may collectively serve to better characterize CRC and shed light on the significance of exosomal non-coding RNAs in CRC diagnosis and prognosis/prediction.

Abstract
Abstract
Introduction
Type 2 diabetes mellitus (T2DM) is a chronic disease of persistent elevation in blood glucose level. Several antidiabetic drugs (ADDs) with different features are currently available for T2DM management (1). The selection of appropriate ADDs is crucial for preventing/attenuating diabetes-related complications(1). All guidelines agreed on metformin to be an initial therapy for patients diagnosed with T2DM, yet the selection of an intensifying therapy or alternative initial therapy are lacking any agreements (1). Consequently, the selection of ADDs could be linked to multiple factors (2). Since obesity is a risk factor for T2DM and ADDs have variable effect on body weight, obesity is an important factor that could be associated with ADDs’ selection.
Aim
This systematic review (SR) and meta-analysis (MA) aimed to overview and quantify obesity association with the selection of ADDs among type 2 diabetic patients.
Methods
A systematic literature search was conducted on multiple databases. Eligible studies were selected based on the following inclusion criteria: quantitative observational studies, evaluated obesity association with ADDs’ prescription, in outpatient setting, and published in English over the period of Jan/2009-April/2021. Studies on other types of diabetes, about switching therapy, or published before 2009 were excluded. The following items were extracted from identified articles: study details as author, year, and method, participants’ characteristics as age and gender, type of investigated ADDs, comparison group, and stage of treatment, as well as type of analysis test. Extracted data was synthesized quantitively utilising a three-level MA approach as some studies reported more than one effect-size because of examining multiple ADDs. It was based on odds ratio and 95%confidence interval.
Results
A total of 21 studies evaluated the association of obesity with ADDs’ prescription was identified. All except one were included in the MA which contributed to a total of 66 effect sizes from all investigated ADDs. The pooled estimate of obesity association with the prescription of ADDs including all groups was 1.19[0.85 -1.67]. A subgroup analysis showed a significant difference according to the type of ADDs (p< .0001). A positive significant association was found with glucagon-Like peptide receptor agonist (GLP1-RA), sodium glucose transporter 2 inhibitors (SGLT2-I), and metformin prescriptions (pooled estimate: 2.35 [1.54-3.59], 1.89[1.33-2.68], and 1.22[1.08-1.37], respectively). Whereas a negative significant association was found with sulfonylurea prescription (pooled estimate: 0.76 [0.62-0.93]). The pooled estimate of thiazolidinedione, dipeptidyl-peptidase 4 inhibitors, and insulin showed a non-significant association with obesity. None of the investigated variables showed significant influence on the overall result including stage of treatment and quality of study (p >0.05).
Conclusion
Obesity is an important factor influencing ADDs’ prescription. Patients with higher weight were more likely to get ADDs with weight losing or neutral effect as GLP1-RA, SGLT2-I, and metformin. This reflects some adherence of clinical practice to the variability in drugs’ features as indicated from the consistent findings of obesity as a factor affecting ADDs’ selection with the weight effect of ADDs. Yet, further studies are required because of limited number of studies examined each antidiabetic group.

Abstract
Abstract
Introduction
The emergence of the COVID-19 pandemic presented unprecedented challenges for healthcare systems, including patients with chronic pain. The COVID-19 lockdown has resulted in limited access to most of the conventional chronic pain management services. Subsequently, changes in opioid utilisation could be expected (1).
Aim
To assess the impact of the first COVID-19 lockdown on opioid utilisation using aggregated-level, community dispensing dataset covering the whole English population.
Methods
This repeated cross-sectional study applied a segmented-linear regression analysis to monthly dispensed opioid prescriptions using the Prescription Cost Analysis database (PCA), from March 2019-March 2021. Opioid utilisation was measured using number of items dispensed/1000 inhabitants and Defined Daily Dose (DDD)/1000 inhabitants/day during 12-months pre and post the COVID-19 lockdown introduced in England in March 2020, stratified by strong and weak opioids.
Results
There were insignificant changes in the number of items dispensed/1000 inhabitants trend pre-COVID-19 lockdown for total, strong, and weak opioids (β1=-0.064, β1=-0.055, β1=0.009, p>0.05, respectively). Immediately post-lockdown, there were small increases in the level of total, strong, and weak opioids (β2=0.494, β2=0.448, β2=0.045) albeit non-significant. There was a non-significant decline in the trend post-lockdown for all opioids’ classes.
Similarly, a non-significant reduction in the DDD/1000 inhabitants/day baseline trend was observed pre-lockdown for total, strong, and weak opioids (β1=-0.028, β1=-0.027, β1=-0.001, p>0.05, respectively). There were immediate increases in the level post-lockdown (β2=0.386, β2=0.360, β2=0.026, p>0.05) for total, strong, and weak opioids respectively. Subsequently, a decline in the trend post-lockdown for all opioids’ classes was observed.
Discussion/conclusion
Unexpectedly, the study’s findings showed an overall stable trend in the utilisation of opioids pre and post COVID-19 in England. The stable trends observed in our study could be due to multiple factors. Firstly, patient level data and information about the specific indication were unavailable in the PCA dataset. This is a limitation as we were unable to examine the trend between the existing and new (incident) patients to obtain more accurate data for opioid utilisation. Moreover, the guidelines and strategies that have been implemented with regard to opioid prescription in the UK (2), to help regulate and minimize the harm from their use in chronic pain management may have had an impact.
To our knowledge, this is the first study to estimate and quantify the impact of the COVID-19 pandemic on opioid utilisation using a segmented regression analysis. This was facilitated by the study focusing on opioid prescription over a 25-month period, i.e. 12 months either side of the pandemic, to predict a trend line for opioid prescription. This duration was beneficial as it gave us adequate time to investigate if COVID-19 had affected prescribing volumes. The limitations include lacking patient level data and specific indications for prescribing opioids. Also, over-the-counter codeine products were not included in the study as the datasets we used included only prescription medicines in ambulatory care
Our findings support the further monitoring and investigation of patient level data to explore the impact of the pandemic on opioid prescription and to continue promoting the safe and effective use of opioids.

Abstract
OBJECTIVES Data on antimicrobial consumption among the paediatric population in public hospitals in South Africa is limited. These needs to be addressed to improve future use and reduce antimicrobial resistance rates. Consequently, the objective is to quantify antimicrobial usage;and identify and classify which antimicrobials are used in the peadiatric population in public sector hospitals in South Africa according to World Health Organiosation (WHO) AWaRe list of antimicrobials METHODS: Conduct a point prevalence survey among 18 public sector hospitals from nine provinces using a newly developed web-based application. The data will be analysed according to the WHO AwaRe list to guide future quality improvement programmes. RESULTS 1261 paediatric patient files were reviewed with 49.7% (627/1261) receiving at least one antimicrobial, with 1013 antimicrobials prescribed overall. The top five antimicrobials included ampicillin (16.4%), gentamycin (10.0%), amoxicillin and enzyme inhibitor (9.6%), ceftriaxone (7.4%), and amikacin (6.3%). Antimicrobials from the Access classification were the most used (55.9%) with 3.1% being from the Reserve classification. The most common infectious conditions were pneumonia (21.3%; 148/1013) and clinical sepsis (16.0%; 111/1013). Parenteral administration (75.6%) and prolonged surgical prophylaxis (66.7%; 10/15) were common and concerns. 28% of the paediatric patients had cultures requested for them before antimicrobial treatment (284/1013) however only 38.7% (110/284) of culture results were available in the files. CONCLUSION Overall, antimicrobial prescribing is common among paediatric patients in South Africa. Interventions should be targeted at improving antimicrobial prescribing, including surgical prophylaxis, and encouraging greater use of oral antibiotics.

Abstract
Objectives: Antimicrobial use is growing, driven mainly by rising demands in developing countries. Knowing how antimicrobials are prescribed is important. Consequently, we undertook a point prevalence survey (PPS) quantifying antimicrobial consumption among 18 public sector hospitals across South Africa.Method: A purpose-built web-based application was used to collect PPS data.Results: Out of 4407 adult patients surveyed, 33.6% were treated with an antimicrobial. The most frequently prescribed groups were a combination of penicillins including β-lactamase inhibitors. Amoxicillin combined with an enzyme inhibitor accounted for 21.4% total DDDs. In the medical and surgical wards, Access antimicrobials (54.1%) were mostly used, while in the ICU, Watch antimicrobials (51.5%) were mostly used. Compliance with the South African Standard Treatment Guidelines and Essential Medicines List was 90.2%; however, concerns with extended use of antimicrobials for surgical prophylaxis (73.2% of patients).Conclusion: The web-based PPS tool was easy to use and successful in capturing PPS data since the results were comparable to other PPS studies across Africa. High use of amoxicillin combined with an enzyme inhibitor, possibly because it was among the broad-spectrum antimicrobials in the Access group. The findings will assist with future targets to improve antimicrobial prescribing among public sector hospitals in South Africa.

Abstract
Objective Determining antimicrobial utilization patterns in hospitals can be a challenge given personnel and resource constraints with paper-based systems. A web-based application (APP) was developed in South Africa to address this, building on a recent point prevalence survey (PPS) using a paper-based system. Consequently, there was a need to test and evaluate the ease of use of a newly developed app and potential time saving versus paper-based methods for PPS. The findings can be used to further refine the APP. Methods The developed app was tested in a large academic public hospital in a PPS in South Africa. During data collection, the app was evaluated for functionality on 35 variables and subsequently refined. After data collection, the app was evaluated in terms of its time-saving potential and ease of use. Results 181 patient’s files were surveyed across 13 wards in the hospital, with the antimicrobial usage findings similar to the previous paper-based study in the same hospital. The median age for males was 45.5 years and 42 years for females. Overall 80 out of 181 (44%) patients received antibiotics. Whilst 38% (12 out of 31) of patients in the adult surgical ward received antimicrobials, the prevalence was the highest (78%) in the pediatric medical wards. All the data collectors were confident in using the app after training and found the tool is not complex at all to use. In addition, the time taken to plan for the study and to collect data was considerably reduced. Reduced time spent in data collection and analysis is important for timely instigation of quality improvement programs in resource limited settings. Conclusions All data collectors would recommend the app for future PPSs. Several concerns with data entry were identified, which have now been addressed. The app development has been successful and is now being deployed across South Africa as part of a national PPS as well as wider.

Abstract
Abstract
Objective
World Health Organization/International Network of Rational use of Drugs (WHO/INRUD) indicators are widely used to assess medicine use. However, there is limited evidence on their validity in Namibia’s primary health care (PHC) to assess the quality of prescribing. Consequently, our aim was to address this.
Design, setting, participants and interventions
An analytical cross-sectional survey design was used to examine and validate WHO/INRUD indicators in out-patient units of two PHC facilities and one hospital in Namibia from 1 February 2015 to 31 July 2015. The validity of the indicators was determined using two-by-two tables against compliance to the Namibian standard treatment guidelines (NSTG). The receiver operator characteristics for the WHO/INRUD indicators were plotted to determine their accuracy as predictors of compliance to agreed standards. A multivariate logistic model was constructed to independently determine the prediction of each indicator.
Main outcomes and results
Out of 1243 prescriptions; compliance to NSTG prescribing in ambulatory care was sub-optimal (target was >80%). Three of the four WHO/INRUD indicators did not meet Namibian or WHO targets: antibiotic prescribing, average number of medicines per prescription and generic prescribing. The majority of the indicators had low sensitivity and/or specificity. All WHO/INRUD indicators had poor accuracy in predicting rational prescribing. The antibiotic prescribing indicator was the only covariate that was a significant independent risk factor for compliance to NSTGs.
Conclusion
WHO/INRUD indicators showed poor accuracy in assessing prescribing practices in ambulatory care in Namibia. There is need for appropriate models and/or criteria to optimize medicine use in ambulatory care in the future.

Abstract
A total of 54 166 mothers delivered at the Riyadh Armed Forces Hospital between 1990 and 1997, including 6119 (11.3%) caesarean sections. Emergency peripartum hysterectomy for obstetric haemorrhage was carried out in 16 cases (0.3/1000 deliveries). The operation followed major degrees of placenta praevia in 12 (75%) cases and atonic postpartum haemorrhage in four (25%). All patients required blood transfusion. There was one neonatal death and no maternal deaths. Although the operation was straightforward, bladder injury occurred in five (31%) cases which was repaired with no residual damage. Placenta accreta was confirmed histologically in 12 (75%) patients. In conclusion, all obstetricians should be aware of the strong association between a scarred uterus, placenta praevia and placenta accreta which can be very adherent and difficult to remove causing bleeding and necessitating hysterectomy. The operation should be performed by an experienced obstetrician before the patient's condition is extreme.

Abstract
237 cattle of a dairy herd in Syria were tested for anti-BLV antibody by the ELISA. 194 animals were additionally examined by the agar gel immunodiffusions test (AGID) on BLV antibodies and 100 by polymerase chain reaction (PCR) for BLV provirus. BLV specific antibodies were determined by means of AGID and ELISA at 62.9% and 69.2% of the examined animals, respectively. Using the PCR method the BLV provirus was detected in 89% of the investigated cattle. Only one ELISA seropositive animal was negative for BLV provirus. The results show the high BLV contamination of this herd and lead to the presumption of wide spread enzootic bovine leukosis in Syria. In the case of the diagnosis of BLV-infection, the PCR-technique compared to the serological tests proved to be much more sensitive. By the detection of BLV antibody, the ELISA showed a higher sensitivity than the AGID and in this way, is advisable as a method of choice for screening investigations. Restriction enzyme and sequence analysis of PCR-amplificates demonstrate that different BLV provirus variants (A, B and C) in the examined herd occur, where the variant C which a high similarity to an Australian BLV provirus isolates showed, occurred most frequently at 92.5%.

Abstract
In a 2-year hospital-based study in Jordan 131 Arab multiple sclerosis patients were identified including 84 Palestinians and 36 Jordanians. Based on MS/ALS case ratio, multiple sclerosis was found to be twice as common among Palestinians than Jordanians. Other than the less marked female preponderance among Jordanian patients, the disease had the same clinical and paraclinical characteristics in both groups. It was more likely for Palestinian and Jordanian patients to originate from the northern parts of their countries, to be Rh negative and to be HLA-DR2 positive than their controls. Palestinians (patients and controls) did not show significant differences from Jordanians (patients and controls) in relation to their eye color, ABO and Rh blood groups distribution nor the HLA-DR or HLA-DQ (apart from HLA-DQ3) epitopes frequency, thus not offering any significant difference in the genetic-racial markers studies to explain the difference in the observed disease susceptibility. Previous studies demonstrated that 2 racially different populations sharing the same environment can have different risk of developing multiple sclerosis, but this study has shown that this can also be true for 2 racially similar populations sharing the same environment.

Abstract
In a 2-year hospital-based study (1992 and 1993), there were 131 multiple sclerosis patients attending 2 large referral hospitals in Jordan. Based on MS/ALS case ratios an overall rate of 32.1 (95% CI 19.7-55.2) was estimated. There were 126 Arabs of whom 84 were Palestinians and 36 indigenous Jordanians. Comparison of these subgroups, which had a similar age distribution revealed that the disease was twice as frequent in Palestinians (estimated 42.0/100,000 (CI 2.8-90.8)) among Jordanians (estimated 20.0/100,000 (CI 9.5-47.2)). Clinical presentation, pattern of disease, disability and HLA association were similar to that in the disease reported in Caucasians in the West. All investigations including neurophysiology and imaging were also very similar to Western reports.

Abstract
Eleven patients with acute diphtheritic neuritis were studied clinically and electrophysiologically. Decreased conduction velocity and increased distal motor latency were present in most patients within two weeks of the onset of neurological symptoms. Velocities later fell to approximately 45% of mean normal values. Wasting with electrophysiological evidence of denervation was present in 3 patients. Nerve conduction studies had returned to normal within 3 months in 8 patients. There was a striking dissociation between the time course of the clinical and the neurophysiological abnormalities: early in the illness, peripheral nerve conduction was normal in some patients despite the presence of severe weakness, and later, the maximum electrophysiological abnormalities were sometimes found after clinical recovery had commenced. The nature and sequence of the clinical and electrophysiological changes are in accord with the known pattern and distribution of the pathological changes in the disease.

Abstract
The frequencies of HLA and B-lymphocyte alloantigens were investigated in 32 Arab patients with clinically definite or early probable multiple sclerosis (M.S.) and compared with those found in 43 healthy Arab controls. A significant association was found between M.S. and the B-lymphocyte alloantigen, BT 102; this contrasts with previous findings of an association between the B-lymphocyte alloantigen BT 101 and M.S. in North Europeans. It is suggested that this difference is due to the involvement of different environmental agents, possibly viruses, in the pathogenesis of M.S. in these populations.
