Abstract
In this work, the effect of adding Magnesium Oxide (MgO) and Titanium Dioxide (TiO2) nanoparticles to enhance the properties of the bone cement used for hip prosthesis fixation. Related to previous work on enhanced bone cement properties utilizing MgO and TiO2, samples of composite bone cement were made using three different ratios (0.5%:1%, 1.5%:1.5%, and 1%:0.5%) w/w of MgO and TiO2 to determine the optimal enhancement ratio. Hardness, compression, and bending tests were calculated to check the mechanical properties of pure and composite bone cement. The surface structure was studied using Fourier transform infrared spectroscopy (FTIR) and Field emission scanning electron microscopy (FE-SEM). Setting temperature, porosity, and degradation were calculated for each specimen ratio to check values matched with the standard range of bone cement. The results demonstrate a slight decrease in porosity up to 2.2% and degradation up to 0.17% with NP-containing composites, as well as acceptable variations in FTIR and setting temperature. The compression strength increased by 2.8% and hardness strength increased by 1.89% on adding 0.5%w/w of MgO and 1.5%w/w TiO2 NPs. Bending strength increases by 0.35% on adding 1.5% w/w of MgO and 0.5% w/w TiO2 NPs, however, SEM scan shows remarkable improvement for surface structure.

Abstract
INTRODUCTION Cataract is a major condition characterized by ocular lens opacification, resulting from alteration in the lens architecture, lens proteins or both. It is responsible for about one-third of infants' blindness worldwide. Variants in the FYCO1 gene have been associated with autosomal recessive infantile cataract. MATERIAL AND METHODS We conducted whole exome sequencing (WES) in a nine months old male patient who was referred for genetic investigation because of infantile cataract. WES analysis revealed the presence of a homozygous pathogenic variant (c.2365C>T) in exon 8 of the FYCO1 gene. RESULTS AND DISCUSSION This is the first report on a Lebanese infant with infantile cataract and cortical atrophy which was not previously reported, resulting from a novel homozygous FYCO1 variant; thus expanding the clinical phenotypic spectrum of FYCO1 involvement.

Abstract
Digital labour platforms have been widely promoted as a solution to the unemployment crisis sparked by the COVID-19 pandemic. However, the pandemic has also highlighted the harms to gig workers-who are exposed either to income loss, or to infection while carrying out essential work, but excluded from labour protections. We examine the COVID-19 policies of 191 platforms in 43 countries to understand how the crisis has shifted the conventions of the gig economy. Using a typology of "fair platform work" we report the introduction of some positive worker protections, but also significant shortfalls, including entrenchment of precarious work as platforms leverage the opportunities arising from the crisis.

Abstract
The reported incidence rate of venous and arterial thrombotic events in critically ill patients with COVID‐19 infections is high, ranging from 20% to 60%. We adopted a patient‐tailored thromboprophylaxis protocol based on clinical and laboratory presentations for these patients in our institution. We hypothesised that patients who received high‐intensity thromboprophylaxis treatment would experience fewer thrombotic events. The aims of our study were to explore the incidence of thrombotic events in this population; to assess independent factors associated with thrombotic events and to evaluate the incidence of haemorrhagic events. A retrospective review of all adult patients with confirmed SARS‐CoV‐2 infection admitted to the intensive care unit (ICU) between 1 March and 29 May 2020 was performed. The primary outcome was a composite of venous and arterial thrombotic events diagnosed during the ICU stay. Multivariable logistic regression was used to identify the independent factors associated with thrombotic events. A total of 188 patients met the inclusion criteria. All received some type of thromboprophylaxis treatment except for six patients who did not receive any prophylaxis. Of the 182 patients who received thromboprophylaxis, 75 (40%) received high‐intensity thromboprophylaxis and 24 (12.8%) were treated with therapeutic anticoagulation. Twenty‐one patients (11.2%) experienced 23 thrombotic events (incidence rate of 12.2% (95%CI 7.9–17.8)), including 12 deep venous thromboses, 9 pulmonary emboli and 2 peripheral arterial thromboses. The multivariable logistic regression analysis showed that only D‐dimer (OR 2.80, p = 0.002) and high‐intensity thromboprophylaxis regimen (OR 0.20, p = 0.01) were independently associated with thrombotic events. Thirty‐one patients (16.5%) experienced haemorrhagic events; among them, 13 were classified as major bleeding according to the International Society on Thrombosis and Haemostasis criteria. Therapeutic anticoagulation, but not the high‐intensity thromboprophylaxis regimen, was associated with major bleeding. A proactive approach to the management of thromboembolism in critically ill COVID‐19 patients utilising a high‐intensity thromboprophylaxis regimen in appropriately selected patients may result in lower thrombotic events without increasing the risk of bleeding.

Abstract
Omega-3 long-chain polyunsaturated fatty acids (LCPUFAS) modulate immune cells in vitro and in vivo. This study investigated the effects of enriching the maternal diet with the n-6 and n-3 LCPUFAs, arachidonic (20:4n-6, 0.6%wt ARA) and docosahexaenoic acid (22:6n-3, 0.32%wt DHA), or 1:1 and 2:1 ratios (ARA: DHA) on total lipids in milk, total lipids, and immunophenotypes in plasma, lymph nodes, and spleen from isolated immune cells from 28d old pups. From day 15 of gestation to day 3 pp, Sprague-Dawley dams were fed a commercial chow. On day 3 pp litters were culled and pups (4 males and 2 females) randomly cross-fostered to dams who were randomized to one of the 5 experimental diets resulting in 20 male and 10 female pups/diet group. Dams fed ARA or ARA: DHA had 28-36% more 20:4n-6 in milk and feeding DHA or ARA: DHA doubled 22:6n-3 in milk lipids (P<0.05). Feeding 1:1 or 2:1 ARA: DHA resulted in greater pup weight at weaning (P<0.05). Compared to the control pups, ARA + DHA fed pups had a lower proportion of splenic CD45RA+ lymphocytes. In summary, postpartum supplementation with a combination of ARA + DHA, compared to ARA or DHA alone, resulted in a higher content of ARA and DHA in dam's milk and tissues and had positive effects on growth, accompanied by evidence of progression toward a mature immune phenotype, and suggests a need for ARA when DHA is supplemented in the early diet. Additional investigations are needed of ARA immunomodulation to better understand and estimate nutritional requirements for LCPUFAs during early development.

Abstract
The aging population is growing increasingly more diverse, with one in four older adults from an ethnic minority group by 2050, while the nursing force will largely remain members of a single race White population. The purpose of this review is to appraise the state of nursing knowledge in relationship to meeting the needs of elders in unique racial/ethnic groups using two approaches: evaluating the efficacy of current knowledge and evaluating the state of nursing knowledge about ethnocultural gerontological nursing based on an integrative review of nursing literature. Thirty-four articles were reviewed. Most articles used qualitative methodology focused on a single ethnic group, with several articles focused on health promotion/prevention. Cultural perspectives were better addressed than aging concepts and few articles integrated ethnocultural and gerontological nursing concepts. This evaluation indicates many gaps in the knowledge base about ethnocultural gerontological nursing. Specific areas for future knowledge development are identified.

Abstract
In this study, we completed the whole genome sequence of a new tobamovirus isolated from tomato plants grown in greenhouses in Jordan during the spring of 2015. The 6393-nt single-stranded RNA (ssRNA) genome encodes four proteins, as do other tobamoviruses: two replication-related proteins of 126 kDa and 183 kDa, a 30-kDa movement protein (MP) and a 17.5-kDa coat protein (CP). Phylogenetic analysis showed that this virus does not group with either the tomato mosaic virus (ToMV) or the tobacco mosaic virus (TMV) clades. Instead, it stems from a branch leading to the TMV clade. Analysis of possible recombination events between this virus and representative isolates of closely related tomato-infecting tobamoviruses showed that at least one region originated by recombination. We provide evidence that we have identified a new tobamovirus, for which we propose the name "tomato brown rugose fruit virus".

Abstract
The steady state compositions of omega-6 and omega-3 polyunsaturated fatty acids (PUFA) throughout the various viscera and tissues within the whole body of rats have not previously been described in a comprehensive manner. Dams consumed diets containing 10wt% fat (15% linoleate and 3% α-linolenate). Male offspring (n=9) at 7-week of age were euthanized and dissected into 25 compartments. Total lipid fatty acids for each compartment were quantified by GC/FID and summed for the rat whole body; total n-6 PUFA was 12wt% and total n-3 PUFA was 2.1% of total fatty acids. 18:2n-6 accounted for 84% of the total n-6 PUFA, 20:4n-6 was 12%, 18:3n-3 was 59% of the total n-3 PUFA, 20:5n-3 was 2.1%, and 22:6n-3 was 32%. The white adipose tissue contained the greatest amounts of 18:2n-6 (1.5g) and 18:3n-3 (0.2g). 20:4n-6 was highest in muscle (60mg) and liver (57mg), while 22:6n-3 was greatest in muscle (46mg), followed by liver (27mg) and carcass (20mg). In terms of fatty acid composition expressed as a percentage, 18:2n-6 was the highest in the heart (13wt%), while 18:3n-3 was about 1.3wt% for skin, white adipose tissue and fur. 20:4n-6 was highest (21-25wt%) in the circulation, kidney, and spleen, while 22:6n-3 was highest in the brain (12wt%), followed by the heart (7.9wt%), liver (5.9wt%), and spinal cord (5.1wt%). Selectivity was greatest when comparing 22:6n-3 in brain (12%) to white adipose (0.08%) (68-fold) and 22:5n-6 in testes (15.6%) compared to white adipose (0.02%), 780-fold.

Abstract
By 2050, for the first time in U.S. history, almost half of elders will be from ethnic minority groups. To meet the needs of this rapidly diversifying population, nurses need to be able to marry transcultural nursing knowledge with gerontological nursing knowledge. The purpose of this article is to propose a new theoretical model for explaining health outcomes and health responses for older individuals in unique ethno-cultural groups and to discuss implications and applications of the model to transcultural gerontological nursing practice and research. The discussion will include (1) an overview of currently available theoretical knowledge in the area, (2) a description of the theory development process, (3) presentation of the proposed ethno-cultural gerontological nursing theoretical model, and (4) discussion of how this model can enhance nursing’s contributions to reducing health disparities. This model is presented not as a finished product but as a basis for future discussion and refinement.

Abstract
As ethnic diversity increases in the United States with the anticipated increase in dementia, it is critical to understand the implications of dementia and culturally appropriate communication for ethnic minority older adults with dementia. Utilizing the Ethno-Cultural Gerontological Nursing model and the Progressively Lowered Stress Threshold model, this article describes the relationship between nursing assistants’ communication style and behavioral symptoms of dementia, focused on Korean American older adults with dementia residing in nursing homes. The discussion includes reviewing currently available studies, nursing implications, and suggestions for future studies.

Abstract
Fusarium wilt or Panama disease of banana, caused by Fusarium oxysporum f. sp. cubense (Foc), is among the most destructive plant diseases (3). Race 1 ravaged 'Gros Michel'-based export trades until the cultivar was replaced by resistant Cavendish cultivars. However, a new variant of Foc, tropical race 4 (TR4), was identified in Southeast Asia in 1992 and has spread throughout the region (3). Cavendish clones, which are most important in subsistence and export production, are among the wide range of cultivars that are affected, and there is a huge concern that TR4 will further disseminate in Africa since its presence was announced in November 2013 and move into Latin America, thereby threatening other vital banana-growing regions. In Jordan, Cavendish bananas are produced on 1,000 to 1,500 ha in the Jordan Valley (32°N, 35.5°E). In 2006, symptoms of Fusarium wilt were observed and sampled for the isolation of Foc. On half-strength PDA amended with 100-ppm streptomycin sulfate, pale salmon-colored colonies with floccose mycelia developed consistently from surface-disinfested xylem. Single microconidia from these colonies were transferred to half-strength PDA, and conidia and mycelia from these monospore colonies were stored at -80°C in 15% glycerol. On banana leaf agar (Co60-irradiated leaf tissue on water agar), isolates resembled F. oxysporum phenotypically by producing infrequent three- to five-celled macroconidia, copious, usually aseptate microconida on monophialides, and terminal and intercalary chlamydospores after 2 weeks (2). With nitrate-nonutilizing (nit) mutants and testers for different vegetative compatibility groups (VCGs), each of seven examined monospore isolates were placed in VCG 01213, which contains only strains of TR4 (3). Total DNA was extracted from six isolates and PCR analyses, which confirmed their identity as TR4 (1). Subsequently, one of the isolates (JV11) was analyzed for pathogenicity. Inoculum production and inoculation were according to (1) by dipping (30 min) root-wounded 10-week-old plants of the Cavendish cv. Grand Naine in 2 liters of spore suspension (1.0 × 106 spores/ml). Inoculated plants were then placed in sand in 3-liter pots under 28°C, 70% relative humidity, and a 16/8-h light/darkness photoperiod. Sets of three plants were each treated with either JV11 or two TR4 controls (isolate II-5 and a strain isolated from an affected Cavendish plant in Mindanao, Philippines, both of which were diagnosed as TR4 by PCR and pathogenicity analyses). Control sets were either treated with race 1 originating from Cruz das Almas, Bahia, Brazil (1), or water. After 2 weeks, plants inoculated with JV11 and TR4 controls produced typical symptoms of Fusarium wilt. After 4 weeks, tissue was collected from all plants and plated on Komada's medium. TR4 was directly confirmed by PCR (1), either directly from symptomatic plants (JV11 and TR4 controls), or from isolates that were recovered from these plants. Nothing was re-isolated from race 1 inoculated plants and water controls, which remained asymptomatic. This is the first report of TR4 affecting Cavendish outside Southeast Asia, is its northernmost outbreak, and represents a dangerous expansion of this destructive race. Currently, 80% of the Jordan Valley production area is affected by Fusarium wilt, and 20 to 80% of the plants are affected in different farms. References: (1) M. A. Dita et al.

Abstract
OBJECTIVE Little is known about the transfer of essential fatty acids (FAs) across the human blood-brain barrier (BBB) in adulthood. In this study, we investigated whether oral supplementation with omega-3 (n-3) FAs would change the FA profile of the cerebrospinal fluid (CSF). METHODS A total of 33 patients (18 receiving the n-3 FA supplement and 15 receiving placebo) were included in the study. These patients were participants in the double-blind, placebo-controlled randomized OmegAD study in which 204 patients with mild Alzheimer's disease (AD) received 2.3 g n-3 FA [high in docosahexaenoic acid (DHA)] or placebo daily for 6 months. CSF FA levels were related to changes in plasma FA and to CSF biomarkers of AD and inflammation. RESULTS At 6 months, the n-3 FA supplement group displayed significant increases in CSF (and plasma) eicosapentaenoic acid (EPA), DHA and total n-3 FA levels (P < 0.01), whereas no changes were observed in the placebo group. Changes in CSF and plasma levels of EPA and n-3 docosapentaenoic acid were strongly correlated, in contrast to those of DHA. Changes in DHA levels in CSF were inversely correlated with CSF levels of total and phosphorylated tau, and directly correlated with soluble interleukin-1 receptor type II. Thus, the more DHA increased in CSF, the greater the change in CSF AD/inflammatory biomarkers. CONCLUSIONS Oral supplementation with n-3 FAs conferred changes in the n-3 FA profile in CSF, suggesting transfer of these FAs across the BBB in adults.

Abstract
BACKGROUND Sunitinib is a tyrosine kinase inhibitor approved for the treatment of renal cell carcinoma (RCC). Few data evaluated severe buccodental adverse events. The aim of this study was to evaluate sunitinib buccodental toxicity in patients with metastatic RCC and to compare it with that of standard chemotherapy in patients with other solid cancers. METHODS Patients with RCC treated with sunitinib and patients with other solid tumours treated with chemotherapy were followed for 3 months. Data on dental appliances, oral hygiene/care practices before and during treatment were collected. RESULTS A total of 116 patients were included (58 RCC treated by sunitinib: group S, and 58 treated by chemotherapy: group C). No differences in dental care habits were noted before treatment. In group S, patients reported significantly more frequent pain (P<0.01), teeth instability (P=0.01), gingival bleeding (P=0.01) and change in teeth colour (P=0.02). In all, 58% of patients in this group had to modify their diet (P<0.01). Frequency of dentist visits for teeth removal was increased (25% vs 8%, P=0.01). CONCLUSION Sunitinib seems to increase buccodental toxicity as compared with chemotherapy. This finding emphasises the need for optimal dental care and standardised dental follow-up in patients treated with sunitinib.

Abstract
The immunodeficiency, centromeric instability and facial anomalies (ICF) syndrome is a rare autosomal recessive disease characterized by targeted chromosome breakage, directly related to a genomic methylation defect. It manifests with phenotypic and clinical variability, with the most consistent features being developmental delay, facial anomalies, cytogenetic defects and immunodeficiency with a reduction in serum immunoglobulin levels. From the molecular point of view, ICF syndrome was always divided into ICF type I (ICF1) and ICF type 2 (ICF2). Mutations in DNMT3B gene are responsible for ICF1, while mutations in ZBTB24 have been reported to be responsible for ICF2. In this study, we describe a Lebanese family with three ICF2 affected brothers. Sanger sequencing of the coding sequence of ZBTB24 gene was conducted and revealed a novel deletion: c.396_397delTA (p.His132Glnfs*19), resulting in a loss-of-function of the corresponding protein. ZBTB24 belongs to a large family of transcriptional factors and may be involved in DNA methylation of juxtacentromeric DNA. Detailed molecular and functional studies of the ZBTB24 and DNMT3B genes are needed to understand the pathophysiology of ICF syndrome.

Abstract
BACKGROUND Sunitinib is a standard of care for metastatic renal cell carcinoma (mRCC). Hypothyroidism is frequently observed under sunitinib therapy. This study was conducted to prospectively determine the correlation between thyroid function and progression-free survival (PFS) in this population. PATIENTS AND METHODS One hundred and eleven mRCC patients treated with sunitinib were evaluated for serum thyroid-stimulating hormone (TSH) and T4 levels before treatment and every 6 weeks during treatment. Survival was analysed according to a landmark method with a cut-off of 6 months, excluding early progressive or early-censored patients. RESULTS Out of the 102 patients with normal baseline thyroid function, 53% developed thyroid dysfunction, including 95% hypothyroidisms out of which 90.9% received L-thyroxine replacement. Median time to TSH alteration was 5.4 months. Median PFS was 11.7 months for the entire population. Median PFS was not different between the groups with abnormal or normal thyroid function after 6 months of treatment (18.9 and 15.9 months, respectively, log-rank P = 0.94, hazard ratio = 1.02, 95% confidence interval = 0.54-1.93). There was no difference even after adjustment for Memorial Sloan-Kettering Cancer Centre classification and therapy line. CONCLUSIONS Abnormal thyroid function with hormonal substitution did not increase survival in our population, independent of initial prognosis and previous treatments. Larger comparative studies are deserved to validate these conclusions.

Abstract
Abstract
Objectives: Mastectomy (Mt) is considered standard treatment for isolated local recurrence (LR) of breast carcinoma. The aim of our study was to evaluate a second conservative treatment (defined as lumpectomy followed by interstitial brachytherapy (LpIB)) and to determine if it compares favorably with the current standard treatment. Materials and methods: Between January 1981 and December 2009, 348 patients were treated to the Paoli Calmettes Institute (IPC) for an isolated LR: 232 (66,7 %) underwent Mt, 62 (17,8 %) received a second radio-surgical conservative treatment (LpIB) and 54 (15,5 %) a 2nd single surgical treatment (Lp).
We classified each population according to the well known prognosis factors.
Then, populations Mt and LpIB were matched taking into account these criteria to compare the overall survival (OS), metastasis free survival (MFS) and 2nd local recurrence free survival according to the treatment delivered.
Results: On 348 reviewed patients, with a median follow-up of 73,3 months, 65 patients died (42/232 Mt, 8/62 TecCur, 15/54 Tec) and 100 presented metastasis (64/232 Mt, 15/62 TecCur, 21/54 Tec). There was no difference in MFS for the 2 groups, LpIB and Mt (80 % at 5 years) and the OS was non significantly better in the group LpIB compared to the group Mt (90 % and 82 % at 5 years respectively, p=0,28), whereas in the LpIB group 17% and 30% presented a relapse at 5 years and 10 years respectively.
They subsequently underwent a salvage mastectomy.
Worse results were obtained with lumpectomy alone (OS = 72 % and MFS = 68 % at 5 years) compared with 2 other option treatments.
Conclusion: A second conservative treatment for breast cancer recurrence, i.e. lumpectomy and interstitial brachytherapy, is possible for selected patients, without any negative impact on overall survival, nor metastasis free survival.
Keywords: Local recurrence, interstitial brachytherapy, lumpectomy, conservative treatment, mastectomy, overall survival, metastasis free survival, breast carcinoma.

Abstract
Abstract
Background. The aim of this retrospective study was to determine by which way was diagnosed any breast cancer recurrence after the end of the adjuvant treatment and to draw guidelines for exams for the follow-up. Materials and methods. Between January 1995 to December 2005, 5419 patients were treated for non metastatic breast cancer in our institute, out of which 662 experienced a relapse either local or metastatic. The charts of 608 of these patients were analysable, and retrospectively reviewed. For each case, we looked at the exams or clinical symptom which revealed the recurrence.
Results. Among the 608 patients who recurred, 173 patients (28%) experienced an isolated local relapse, while 12 experienced a contralateral breast cancer (2%), 423 experienced either a metastatic or metastatic plus local relapse (65% and 5%, respectively). Local relapses were detected in most of cases either clinically (42%) or on mammography and mammary ultrasound (US) (55%). An isolated increase of blood tumor marker (CA 15.3) revealed the relapse in 24% of cases (in 33% of cases for distant relapses and 3% for isolated local relapses). The remaining 67% of cases with metastases were diagnosed by clinical symptoms in 47% of cases, imaging in 22% of cases (bone scan in 6%, liver US 5%, mammography 1%, TDM 5%, chest X-ray 2%). In these cases of radiographically detected metastases clinical exam and/or tumor markers levels were abnormal in 42% of cases.
Conclusion. A follow-up with a systematically clinical exam, mammography and mammary US, and blood tumor markers assessment permits the diagnosis of 100 percent of local relapse, 100% of contralateral breast cancer, and 89% of metastatic disease. Thus imaging exams could be avoided routinely, with less stress for the patient and improvement of the health cost.
