Abstract
Post-operative cognitive dysfunction (POCD) is a debilitating clinical phenomenon in elderly patients. Management of pain in elderly is complicated because analgesic opiates elicit major side effects. In contrast, paracetamol (acetaminophen) has shown analgesic efficacy, no impact on cognition, and its side effects are well tolerated. We investigated the efficacy of paracetamol, compared to the opioid analgesic buprenorphine, in a model of POCD by investigating cognitive decline, allodynia, peripheral and hippocampal cytokines levels, and hippocampal microtubule dynamics as a key modulator of synaptic plasticity. A POCD model was developed in middle-aged (MA) rats by inducing a tibia fracture via orthopaedic surgery. Control MA rats did not undergo any surgery and only received isoflurane anaesthesia. We demonstrated that cognitive decline and increased allodynia following surgery was prevented in paracetamol-treated animals, but not in animals which were exposed to anesthesia alone or underwent the surgery and received buprenorphine. Behavioral alterations were associated with different peripheral cytokine changes between buprenorphine and paracetamol treated animals. Buprenorphine showed no central effects, while paracetamol showed modulatory effects on hippocampal cytokines and markers of microtubule dynamics which were suggestive of neuroprotection. Our data provide the first experimental evidence corroborating the use of paracetamol as first-choice analgesic in POCD.

Abstract
Background: Colorectal cancer (CRC) incidence is progressively increasing in Egypt. Unfortunately, there is inadequate knowledge of the acquired somatic mutations in Egyptian CRC patients which limit our understanding of its progression. To the best of our knowledge, our study is the first to sequence multiple-gene panel to identify the somatic mutation pattern associated with CRC disease progression in a cohort of Egyptian patients. Custom 72 genes, which are frequently associated with CRC, were sequenced using Qiaseq UMI-based targeted DNA panel in 120 fresh tissues classified into; inflammatory bowel disease (IBD; n=20), colonic polyp (CP; n=38) and CRC (n=62) as well as 20 biopsies with non-specific colitis served as a control group (n=20). Results: Using Ingenuity Variant Analysis (IVA), we revealed that APC, TP53 & ATM genes harbored the highly frequent CRC-specific somatic mutations (15, 11 & 6, respectively). We also identified common somatic mutations (predictors) that were associated with disease progression from colitis to CRC; APC (c.1742delA (65%)), TP53 (c.121delG (58%), c.215C>G (52%)), ATM (c.640delT (16%)), IGF2 (c.677delG (56%)), RET (c.2071G>A (37%)), ACVR2A (c.1310delA (26%)), PIK3CA (c.1173A>G (16%)) & KIT (c.1621A>C (13%)). Furthermore, pathway analysis using Ingenuity Pathway Analysis (IPA) showed that Wnt/βcatenin, ATM signaling, RTK-RAS and TGF-β were the most altered pathways in the CRC group (73%. 72%, 40% & 36%, respectively).Conclusion: In this data set, we shed the light on the most frequent somatic mutations and the most altered pathways that are crucial for understanding colorectal cancer predisposition and developing personalized therapies for the Egyptian CRC patients.

Abstract
Introduction: Many studies have reported the role of vitamin D in rheumatoid arthritis (RA) which is related to several serum autoantibodies such as RF and Anti CCP. It also has been shown that vitamin D deficiency affect the DAS28 and VAS score inversely. Therefore, we aim to assess the relationship between vitamin D deficiency and RA-related autoantibodies including Anti CCP and RF levels and also evaluate the association between these parameters and the severity of disease.Methods: In this cross-sectional study, RA patients over 16 years of age were enrolled. The severity of diseases was assessed via the DAS28 scoring system. Serum levels of 25(OH) vitamin D were determined by the ELISA method, along with other rheumatoid related laboratory evaluations including Anti CCP, RF and CRPResults: A total of 100 patients with a mean age of 45.27± 14.14 were included and evaluated; of them, 75% were female and 77% lived in the city. Most of the patients (66%) had moderate DAS28 levels; however, no substantial relationship was observed between DAS28 and vitamin D levels. A significant positive relation between serum 25(OH)D level and disease duration, as well as the level of education, was observed. There was also no significant correlation between RA-related autoantibodies and inflammatory serum marker with 25(OH)D.Conclusion: Due to vitamin deficiency in the majority of cases (73%) and the relationship between serum 25(OH)D levels and the duration of disease, it can be concluded that vitamin D levels should be checked in those patients.

Abstract
Introduction Advances in neonatal care have led to the increasing survival of preterm/low birth weight infants worldwide. However, there is limited data on growth outcomes following preterm births especially in low and middle income countries. We assessed the catch-up growth, nutritional status and associated factors of Ugandan children who were born preterm/ low birth weight at Mulago National Referral Hospital.Methods: We enrolled children aged 22-38 months who had been born as preterm with low birth weight and their mothers. Participants were identified and recruited from the follow up clinic for preterm babies discharged from the neonatal unit of Mulago Hospital. Anthropometric measurements for mothers and children were taken. The children’s weight for height z-scores, height for age z-scores, weight for age z-scores, head circumference and mid upper arm circumference (MUAC) were taken and the mothers’ body mass index were generated based on the World Health Organization standards. Results: Of the 251 children and mother pairs recruited, 129 children (51.4%) were male, the mean age was 29.7 months (SD±4.5) and the mean maternal age was 29.9 (SD±5.3). 101(40.1%) of the children enrolled had attained catch up growth on the normal anthropometric measurements for their age. Among the participants, the prevalence of wasting, underweight and stunting was: 8 (3.2%), 36 (14.4%) and 106 (42.2%) respectively. Factors associated with stunting were male sex (AOR 2.36, 95% CI 1.42 to 3.95); p=0.001), maternal age ≤ 25years: AOR 2.27 (95%CI 1.13, 4.52); p= 0.020, and maternal height <150cm: AOR 5.57(95%CI 1.90, 16.94); P=0.002. Associations with underweight in the children were; birth weight ≤1500 gms: AOR 2.38(95%CI 1.14, 4.95); p=0.020 and post-natal hospitalization of more than 14 days: AOR 5.93(95%CI 1.96, 17.90); p=0.002. For 246 (98.8%) participants, MUAC was normal (≥ 12.5 cm) and for 216 (86.8%) the head circumference was within normal range for age.Conclusion: Of the children born preterm/LBW 40.1% of the participants had attained the expected catch up growth at 2 to 3 years of age, 42.2% were observed to be stunted while 14.4% were underweight both higher than the national levels. Targeted interventions are specifically needed for children born with very low birth weight, those requiring long postnatal hospitalization, males and those born to short or young mothers.

Abstract
Background: Stroke is a devastating and debilitating disease and is a leading cause of death worldwide, including intracerebral hemorrhage (ICH) and ischemic stroke. Emerging evidence indicates that inflammatory cascades after hemorrhagic or ischemic stroke makes a great contribution to brain damage, mainly are involved in neuronal cell death, blood-brain-barrier (BBB) destruction and development of vasogenic edema. However, the features and direct effect of brain inflammation following stroke is still unknown. Methods: We adopted the ICH model by injection of collagenase and used a mouse model of transient cerebral ischemia and reperfusion. And pertussis toxin was used to create a pro-inflammatory milieu. Neurodeficits, lesion volume, production of reactive oxygen species (ROS) and inflammatory factors, brain-infiltrating leukocytes and blood-brain-barrier (BBB) destruction were assessed in mice model treated with pertussis toxin or vehicle.Results: Adopting collagenase induced intracerebral hemorrhage mouse model, we show that pertussis toxin-induced systemic inflammation exacerbated neurological deficits, enlarged lesion size and brain perihematomal edema after intracerebral hemorrhage. Pertussis toxin promoted leukocyte infiltration and inflammatory cytokine release in the brain. Moreover, the integrity of the BBB was further disrupted after receiving pertussis toxin in ICH mice. Furthermore, we demonstrated that pertussis toxin increased stroke severity and enhanced brain inflammation in middle cerebral artery occlusion (MCAO) mouse model. Conclusion: Our results suggest that pertussis toxin increases inflammatory response that exacerbates brain injury after intracerebral hemorrhage or ischemic stroke in mouse model.

Abstract
Background: Tuberculosis (TB) is the leading infectious cause of mortality worldwide. In the last years, resistant strains of the etiological agent, Mycobacterium tuberculosis, have emerged, thus demanding more triage tests to identify active pulmonary TB (PTB) patients and to evaluate their disease severity. Therefore, acute-phase reaction serum tests are required for monitoring TB patients, among WHO symptoms screening recommendations. C-reactive protein (CRP) is a non-specific inflammatory biomarker that has been recently proposed for TB screening and can be quantitatively analyzed through cost-effective point-of-care assays. A previous meta-analysis found CRP high sensitive and moderate specific for active pulmonary TB with confirmed HIV infection. Methods: We performed an update meta-analysis of diagnostic tests, pooling sensitivities and specificities in order to assess the accuracy of CRP as a potential test for the screening of HIV-associated PTB in outpatients. We searched MEDLINE, Web of Science, and SCOPUS, for eligible articles before April 1st, 2020. Results: We identified 9 eligible studies with HIV-positive patients with PTB. At CRP threshold of 10mg/L, CRP pooled sensitivity was 86% and pooled specificity was 73%. Using CRP threshold of 8mg/L, pooled sensitivity was 81% and pooled specificity was 88%. We found that CRP has a high sensitivity in screening of PTB in HIV-positive outpatients, consistent with findings reported previously. Conclusions: Regardless of pooled specificity, better results were found using the CRP threshold of 8mg/L as a test screening of PTB, meeting the need of evaluation of antituberculosis treatment outcomes and reducing resource consumption.

Published: December 2020

Abstract
Background: Currently, social media has been used to disseminate contents of scientific articles. In order to measure this type of impact a new tool named Altmetric was created. Altmetric aims to quantify the impact of each article through the media online. This overview of methodological reviews aims to describe the associations between the publishing journal and the publishing articles variables with Altmetric scores. Methods: Search strategies on MEDLINE, EMBASE, CINAHL, CENTRAL and Cochrane Library. We extracted data related to the publishing trial and the publishing journal associated with Altmetric scores. Results: A total of 11 studies were considered eligible. These studies summarized a total of 565,352 articles. The variables citation counts, journal impact factor, access counts, papers published as open access and press release generated by the publishing journal were associated with Altmetric scores. The magnitudes of these correlations ranged from weak to moderate. Conclusion: Citation counts and journal impact factor are the most common associators of high Altmetric scores. Other variables such as access counts, papers published in open access journals and the use of press releases are also likely to influence online media attention.Systematic Review registrations: Not applicable

Published: December 2020

Abstract
Background: Seeds are the economic basis of oilseed crops, especially for soybean, thus far the most widely cultivated oilseed crop worldwide. Seed development is accompanied with a multitude of diverse cellular processes and revealing the underlying regulatory activities is critical for seed improvement. Results: Here, we profiled transcriptomes of developing seeds (20, 25, 30, 40 days after flowering) representing key points of seed development from early to full development. We identified a set of highly-abundant genes and highlighted the importance of these genes to support nutrient accumulation and transcriptional regulation in developing seeds. We identified 8,925 differentially expressed genes that exhibited temporal expression patterns over the course and had expression specificities in distinct tissues including seeds and non-seed tissues (roots, stems, leaves). Genes with specificities to non-seed tissues have tissue-specialized roles while remain relatively low transcript abundance in developing seeds, exhibiting their supportive roles spatially for seed development. Co-expression network analysis identified several under-explored genes in soybean that bridge tissue-specific gene modules. Conclusions: Our study provides a global view of gene activities and biological processes critical for seed formation in soybean and prioritizes a set of genes for further study. The results shed insight into the mechanism controlling seed development and storage reserves.

Abstract
Background: High tibial osteotomy (HTO) is an effective treatment for varus knee osteoarthritis. However, obese patients require reinforced internal fixation materials to prevent internal fixation fractures and hardware failure after osteotomy. Thus, the purpose of our study was to evaluate the clinical efficacy of distal tibial tuberosity high tibial osteotomy (DTT-HTO) using the new patented π-plate in obese patients with varus knee osteoarthritis.Methods: Thirty-four obese patients (39 knees) with varus knee osteoarthritis who underwent DTT-HTO with the π-plate and second-look arthroscopy when implant removal occurred from September 2017 to June 2020 were retrospectively reviewed. There were 9 males and 25 females, with body mass index (BMI) values ranging from 30.3 to 38.5 kg/m2 and ages ranging from 50 to 75 years old. The radiological assessment was performed with the weight-bearing line ratio (WBLR). The clinical outcomes were evaluated by the Hospital for Special Surgery (HSS) knee score and the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC). The status of the cartilage was evaluated by the International Cartilage Repair Society (ICRS) grading system. Results: All patients were followed up for 18-30 months. The WBLR significantly increased from 16.85±2.20 to 55.41±2.46% from before surgery to the last follow-up after surgery (P<0.001). The HSS score significantly improved from 56.65±5.27 preoperatively to 68.79±2.61, 77.82±2.15, and 86.12±2.78 at the 6-month, 12-month, and last follow-up after surgery (P<0.001). The WOMAC score significantly decreased from 105.47±3.89 preoperatively to 80.50±4.20, 71.44±4.65, and 52.44±3.14 at the 6-month, 12-month, and last follow-up after surgery (P<0.001). During implant removal, no internal fixation fractures occurred in any patient. The articular cartilage grade in the medial compartment of the knee were significantly higher in the second arthroscopy than in the first arthroscopy, according to the ICRS grading system (P < 0.001). The articular cartilage grade in the lateral compartment of the knee showed no statistical differences from the first- to the second-look arthroscopy (p > 0.05).Conclusions: The new patented π-plate is an effective internal fixation material to provide good structural stability in DTT-HTO. And DTT-HTO using the π-plate can yield excellent clinical results in obese patients with varus knee osteoarthritis.

Published: December 2020

Abstract
Background: This study was performed to develop and validate machine learning models for the early detection of ventilator-associated pneumonia (VAP) in patients 24 h before the diagnosis that enables VAP patients to receive early intervention and reduces the occurrence of complications.Patients and Methods: This study was based on the MIMIC-III dataset, which was a retrospective cohort. The random forest algorithm was applied to construct a base classifier, and the area under the receiver operating characteristic (ROC) curve (AUC), sensitivity and specificity of the prediction model were evaluated. Meanwhile, a Clinical Pulmonary Infection Score (CPIS)-based model (threshold value≥3) using the same training and test data set was used as the control model.Results: A total of 38,515 ventilation durations occurred in 61,532 ICU admissions. VAP occurred in 212 of these durations. We incorporated 42 VAP risk factors on admission and routinely measured vital characteristics and laboratory results. Five-fold cross-validation was performed to evaluate the model performance, and the model achieved an AUC of 84.4%±1.7% on validation, 74.3%±2.5% sensitivity and 70.7.6%±1.2% specificity 24 h before the gold standard time (at least 48 h after ventilation). Our VAP machine learning model improved the AUC of the CPIS-based model by almost 25%, and the sensitivity and specificity were also improved by almost 14% and 15%, respectively.Conclusions: We developed and internally validated an automated model of VAP prediction in the MIMIC-III cohort. The VAP prediction model achieved high performance for AUC, sensitivity and specificity. and its performance was superior to that of the CPIS model. External validation and prospective interventional or outcome studies using this prediction model are envisioned as future work.

Abstract
Background: Targeted lung denervation (TLD) is a novel bronchoscopic therapy that disrupts parasympathetic pulmonary nerve input to the lung reducing clinical consequences of cholinergic hyperactivity. The AIRFLOW-1 study assessed safety and TLD dose in patients with moderate-to-severe, symptomatic COPD. This analysis evaluated the long-term impact of TLD on COPD exacerbations, pulmonary function, and quality of life over three years of follow up.Methods: TLD was performed in a prospective, energy-level randomized (29 W vs 32 W power), multicenter study (NCT02058459). Additional patients were enrolled in an open label confirmation phase to confirm improved gastrointestinal safety after procedural modifications. Durability of TLD was evaluated at one, two, and three years post-treatment and assessed through analysis of COPD exacerbations, pulmonary lung function, and quality of life. Results: Three-year follow-up data were available for 73.9% of patients (n=34). The annualized rate of moderate to severe COPD exacerbations remained stable over the duration of the study. Lung function (FEV1, FVC, RV, and TLC) and quality of life (SGRQ-C and CAT) remained stable over three years of follow-up. No new gastrointestinal adverse events and no unexpected serious adverse events were observed. Conclusion: TLD in COPD patients demonstrated a positive safety profile out to three years, with no late-onset serious adverse events related to denervation therapy. Clinical stability in lung function, quality of life, and exacerbations were observed in TLD treated patients over three years of follow up.
