ACE2-Fc and DPP4-Fc decoy receptors against SARS-CoV-2 and MERS-CoV variants: a quick therapeutic option for current and future coronaviruses outbreaks.

The severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) and the Middle East respiratory syndrome coronavirus (MERS-CoV) are highly pathogenic human coronaviruses (CoVs). Anti-CoVs mAbs and vaccines may be effective, but the emergence of neutralization escape variants is inevitable. Angiotensin-converting enzyme 2 and dipeptidyl peptidase 4 enzyme are the getaway receptors for SARS-CoV-2 and MERS-CoV, respectively. Thus, we reformatted these receptors as Fc-fusion decoy receptors. Then, we tested them in parallel with anti-SARS-CoV (ab1-IgG) and anti-MERS-CoV (M336-IgG) mAbs against several variants using pseudovirus neutralization assay. The generated Fc-based decoy receptors exhibited a strong inhibitory effect against all pseudotyped CoVs. Results showed that although mAbs can be effective antiviral drugs, they might rapidly lose their efficacy against highly mutated viruses. We suggest that receptor traps can be engineered as Fc-fusion proteins for highly mutating viruses with known entry receptors, for a faster and effective therapeutic response even against virus harboring antibodies escape mutations.

Causes and Pattern of Chest Trauma Among Adults: A Scoping Review of Studies From the Middle East.

Chest trauma incidence is increasing worldwide, and it requires attention as it is a major cause of morbidity and mortality. Worldwide, chest trauma is the second most common cause of mortality and a major cause of disability and hospitalization. Our main aim is to systematically review the prevalence, pattern, causes, manner, morbidity, and mortality of chest trauma in the Middle East among adults. This scoping review was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Screening of the relevant articles was done by using databases, including PubMed, Scopus, and Web of Science. A total of 128 articles were found as a result of searching the databases and reviewing the reference lists. Finally, nine articles met the inclusion criteria. Most of the victims were males, as reported by all studies in this systemic review. The most common cause of chest trauma was road traffic accident (RTA), as described in seven out of the nine included studies. The pattern of chest trauma included pneumothorax, hemothorax, hemopneumothorax, lung contusion, flail chest, rib fracture, and diaphragmatic injury. The rate of mortality and morbidity following chest trauma varied among the studies. However, most of the studies revealed higher rates of morbidity than mortality. Chest trauma carries economic and social burdens, and it is a serious issue, especially in males in the second to third decades. Preventive measures should be considered to decrease the prevalence of chest trauma and its related complications.

COVID-19 in patients with rheumatological diseases in the Eastern Province of Saudi Arabia.

The severity of the 2019 coronavirus disease (COVID-19) and its effects remain unpredictable. Certain factors, such as obesity, hypertension, and type 2 diabetes mellitus, may increase the severity of the disease. Rheumatology experts suggest that patients with active autoimmune conditions and controlled autoimmune diseases on immunosuppressive therapy may be at higher risk of developing severe COVID-19. In this retrospective observational study, we aimed to examine the patterns of COVID-19 in patients with underlying rheumatological diseases and their association with disease severity and hospital outcomes. A total of 34 patients with underlying rheumatological diseases who tested positive for severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) by polymerase chain reaction (PCR) were included between March 2020 and April 2021 at King Fahd Hospital of the University. The study population consisted of 76.47% female and 23.53% male patients, with a mean age ranging from 20 to 40 years. Female gender (p=0.0001) and younger age (p=0.004) were associated with milder disease. The most frequent rheumatological disease was systemic lupus erythematosus (SLE) (38.24%), which was associated with a milder infection (p=0.045). Patients treated with mycophenolate mofetil (MMF) had a milder disease course (p=0.0037). Hypertension was significantly associated with severe COVID-19 disease (p=0.037). There was no significant relationship between SLE and the need for ICU admission. Patients on hydroxychloroquine and MMF tended to develop milder disease, and there was no association between the severity of the infection and the treatment with steroids.

Construction of VSVΔ51M oncolytic virus expressing human interleukin-12.

The use of oncolytic viruses (OVs) in combination with cytokines, such as IL-12, is a promising approach for cancer treatment that addresses the limitations of current standard treatments and traditional cancer immunotherapies. IL-12, a proinflammatory cytokine, triggers intracellular signaling pathways that lead to increased apoptosis of tumor cells and enhanced antitumor activity of immune cells via IFN-γ induction, making this cytokine a promising candidate for cancer therapy. Targeted expression of IL-12 within tumors has been shown to play a crucial role in tumor eradication. The recent development of oncolytic viruses enables targeted delivery and expression of IL-12 at the tumor site, thereby addressing the systemic toxicities associated with traditional cancer therapy. In this study, we constructed an oncolytic virus, VSVΔ51M, based on the commercially available VSV wild-type backbone and further modified it to express human IL-12. Our preclinical data confirmed the safety and limited toxicity of the modified virus, VSV-Δ51M-hIL-12, supporting its potential use for clinical development.

Emergence of Post COVID-19 Vaccine Autoimmune Diseases: A Single Center Study.

Introduction: Severe acute respiratory syndrome coronavirus 2 (SARS CoV-2) became a major concern since the announcement that it is a pandemic in early 2020. Vaccine trials were started in November 2020, and completed rapidly due to the urgency to get over the infection. Side effects to vaccines started to be reported. There were minor side effects including site of injection pain and heaviness and constitutional symptoms like fever which are considered minor. One of the rare adverse events is post vaccine new onset autoimmune diseases. Methods: Data were obtained from one center in the eastern province of Saudi Arabia (King Fahd Hospital of University). All patient events reported occurred in the study period March 2021 to February 2022. We identified patients presenting with autoimmune diseases with exclusively new onset presentations. Results: We identified 31 cases of immune-mediated disease: 18 females (58%); 13 males (42%). Only 4 of them (13%) had an autoimmune background before COVID-19 vaccination. The average time between vaccination and new-onset disease symptoms was 7 days. Among all the cases in our study, 7 patients (22.5%) had new-onset vasculitis, 2 cases had IgA vasculitis and 5 cases had ANCA vasculitis, 6 cases had neurological diseases (19.3%), 4 cases (12.9%) had new-onset systemic lupus erythematosus (SLE), 3 cases (9.6%) presented with new-onset inflammatory arthritis, and one had Sjogren's syndrome (3.2%). Conclusion: Our study is unique as it is the first study to include the largest number (31 patients) of new onsets of confirmed autoimmune diseases related to Covid-19 vaccines.

The association between serum ferritin and bilirubin with glycemic control among patients with type 2 diabetes mellitus.

Previous evidence has shown an association between serum ferritin and bilirubin levels in the development of type 2 diabetes mellitus (T2DM) and glycemic control. However, the evidence is scarce in Saudi Arabia. In this study, we aimed to evaluate the association between serum ferritin and bilirubin levels with glycemic control in patients with T2DM. This was a cross-sectional study that involved 153 patients with T2DM recruited from outpatient diabetes clinics. Participants were categorized into two groups: well-controlled and uncontrolled T2DM, based on their glycemic status. We focused on comparing the iron profile and bilirubin levels between these two groups and examining the influence of antidiabetic medications on these parameters. A total of 153 patients with T2DM were included (58.2% women and 41.8% men). In both univariate and multivariate analyses, ferritin levels did not have a statistically significant association with glycemic control. However, patients with well-controlled T2DM had a significantly higher median level of total bilirubin and direct bilirubin than those with uncontrolled T2DM. Only direct bilirubin showed a statistically significant association with FBG less than 130 mg/dl and HbA1c level less than 7.0%. Ferritin level was not associated with glycemic control in patients with T2DM. On the other hand, direct bilirubin level was an independent predictor of better glycemic control. Monitoring direct bilirubin levels could aid in predicting glycemic control in T2DM and could be a potential target for developing antidiabetic medications.

Hepatobiliary manifestations of COVID-19 and their impact on severity and outcomes in a single center in Saudi Arabia.

Recognizing hepatic manifestations of COVID-19 and their impact on the severity and outcome is crucial in managing this emerging pandemic. However, we lack such reported data in Saudi Arabia regarding this clinical entity. This is a retrospective observational study conducted on 387 patients with COVID-19 disease who were hospitalized at King Fahad Hospital of the University from March-September 2020. The total cohort was divided into two groups: liver and non-liver involvement. Then, the frequency of hepatic manifestations was determined, followed by comparing severity and outcome among the two study groups. A total of 387 patients were included, of which 72.87% had hepatic manifestations. The most prevalent abnormalities were high LDH in 308 (79.58%) followed by AST 205 (52.97%), GGTP 124 (31.26%), ALT 74 (19.12%), PT/INR 66 (17.05%), direct bilirubin 51 (12.40%), total bilirubin 46 (11.88%), and low albumin 48 (12.4%). Univariate analyses showed that liver involvement was significantly associated with severe (31.91%) and critical (34.75%) presentation (P<0.001). Multivariate regression analysis showed that the presence of liver involvement was an independent risk factor for severe or critical COVID-19 disease (OR 2.44; P<0.001), longer hospitalization (OR 2.27; P=0.001), and ICU admission (OR 2.27; P=0.006). The current study showed that liver involvement is common in the setting of COVID-19 disease. Such patients had a higher disease severity and a worse clinical outcome.

Clinical outcome of pre-operative blood transfusion for sickle cell disease patients in post-operative complications.

BACKGROUND: Preoperative blood transfusion for patients with sickle cell disease is a debatable topic and it can be lifesaving. Sickle cell disease patients are at high risk for vaso-occlusive crisis due to the large concentration of sickle hemoglobin (HgbS) in their blood. Despite the current extensive research into this disease, there is still no consensus over whether blood transfusion is a preferable preoperative modality among patients undergoing elective surgical procedures. METHOD: A retrospective observational study, which enrolled 204 patients with Sickle cell disease who underwent surgery at King Fahad Hospital of the University (KFHU) over the last five years. The primary objective was to determine whether there is evidence that preoperative blood transfusion for SCD patients undergoing surgical procedures will reduce postoperative complications related to SCD. RESULTS: A total of 204 patients were included, of which 30% had preoperative blood transfusion. Majority of patient 44% had undergone cholecystectomy. On multivariate logistic regression analysis, patients who did not undergo blood transfusion had significantly higher risk to develop post-operative SCD complications (OR = 3.07, P value = 0.002). In addition, they had significantly prolonged hospitalization (OR = 2.22, P value = 0.08). In contrast, patients who received blood transfusion had lower risk for developing post-operative SCD-related complications (OR = 1.87, P value = 0.29), and decrease in the duration of hospitalization by (OR = 0.49, P value = 0.045). CONCLUSION: Our study showed that patients who had not undergone preoperative blood transfusion had higher risk to develop postoperative complications and prolonged hospital stay compared to those who underwent blood transfusion.

The Impact of Vaccination Against SARS-CoV-2 Virus on the Outcome of COVID-19 Disease.

Background: Coronavirus disease 2019 (COVID-19) is a rapidly spreading infection that is on the rise. New variants are continuously appearing with variable degrees of lethality and infectivity. The extensive work since the start of the pandemic has led to the evolution of COVID-19 vaccines with varying mechanisms. We aim to determine real-world data by looking at the different clinical outcomes associated with COVID-19 vaccination, focusing on the rate of hospitalization, severity, and mortality. Methodology: A retrospective observational study included 624 patients with COVID-19 infection who were hospitalized at King Fahad Hospital of the University and King Fahad Military Medical City between April and July 2021. The cohort was divided into 3 groups: unvaccinated, partially vaccinated (PV), and fully vaccinated (FV). The severity and outcome of COVID-19 disease were compared among the three groups. Among the vaccinated group, we studied the effect of vaccine type on the severity and outcome of COVID-19 disease. Results: We found that 70.4% of patients with COVID-19 disease who required hospitalization were unvaccinated. Un-vaccination was a significant predictor of critical COVID-19 disease (OR 2.31; P <0.001), whereas full vaccination was associated with significantly milder disease severity (OR 0.36; P 0.01). Moreover, un-vaccination status was an independent predictor of longer hospitalization (OR 3.0; P <0.001), a higher requirement for ICU admission (OR 4.7; P <0.001), mechanical ventilation (OR 3.6; P <0.001), and death (OR 4.8; P <0.001), whereas the FV group had a lower risk of ICU admission (OR 0.49; P 0.045). Unvaccinated patients with comorbidities had worse severity and outcome of COVID-19 infection (P<0.05). Both vaccine types (Pfizer and AstraZeneca) had similar protective effects against the worst outcomes of COVID-19 disease. Conclusion: COVID-19 vaccination has been shown to be effective in reducing hospitalization, the severity of COVID-19 infection, and improving outcomes, especially in high-risk group patients. COVID-19 vaccination programs should continue to improve the outcome of such a disease.

Amplifying Lateral Flow Assay Signals for Rapid Detection of COVID-19 Specific Antibodies.

Rapid lateral flow immune-assays are point-of-care diagnostic tools that are easy to use, cheap, and do not need centralized infrastructure. Therefore, these devices are appealing for rapid detection of the humoral immune responses to infections, particularly severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The novel technique introduced here uses a complex of anti-SARS-CoV-2 N-protein antibodies conjugated to gold nanoparticles that are bound to five SARS-CoV-2 N protein conjugated to gold nanoparticles to amplify the signals obtained from the conjugated SARS-CoV-2 N protein and to enhance the assay detection limit. To validate the performance of the adopted lateral flow, serum from SARS-CoV-2 seropositive individuals and prepandamic negative samples are tested and compared to a validated enzyme-linked immunosorbent assay (ELISA) for the detection of SARS-CoV-2 N protein specific IgG and IgM antibodies. The data shows that the designed lateral flow assay has an excellent sensitivity and specificity upon detecting IgM and IgG antibodies by applying only 2 µL from the serum sample to the adopted strips. Taken together, the developed lateral flow immunoassay assay provides a rapid, specific, and highly sensitive means to detect the immune responses against SARS-CoV-2 with only 2 µL from the serum sample.

Gastrointestinal manifestations of COVID-19 in a single center in the Eastern Province of Saudi Arabia.

Background: Several gastrointestinal (GI) symptoms have been associated with novel coronavirus disease-2019 (COVID-19). Their prevalence and relation to the severity and hospital outcome of COVID-19 have not been well reported in the Middle East and Saudi Arabia. We aimed to examine the GI manifestations of COVID-19 and their association with the severity and hospital outcome of COVID-19 infection. Methods: We conducted a retrospective observational study of hospitalized COVID-19 patients who had a positive SARS-COV2 PCR test and were admitted at a university hospital in Saudi Arabia, from March to September 2020. The primary objective of the study was to describe the GI manifestations of COVID-19. The secondary objective was to investigate the association of GI manifestations with severity and outcome of COVID-19 infection. Results: We included 390 patients, of which 111 (28.5%) presented with GI manifestations. The most common presentation was diarrhea followed by nausea, vomiting, and abdominal pain. Patients without GI manifestations had a higher risk of severe-critical COVID-19 infection evident by the development of lung infiltration in more than 50% of lung fields within 24-48 h, acute respiratory distress syndrome, altered mental status, multiorgan failure, and cytokine storm syndrome (P < 0.05). These patients had a higher mortality rate compared to patients with GI manifestations (P = 0.01). A lower odds of death was seen among patients with GI symptoms (AOR 0.36; 95% CI, 0.158-0.82; P = 0.01). Conclusion: COVID-19 infection presents commonly with GI manifestations. Patients with GI manifestations have less severe COVID-19 disease and lower mortality rates.

Delayed Hemolytic Transfusion Reaction in Sickle Cell Disease: A Case Series.

BACKGROUND Transfusion therapy has a well-established role in the management of several sickle cell disease (SCD)-related complications. Nevertheless, the benefits of transfusion must outweigh the possible risks, including iron overload, infections, and transfusion reactions. Alloimmunization is the underlying etiology of most delayed hemolytic transfusion reactions (DHTR). DHTR is often underestimated and underdiagnosed in sickle cell disease patients as it mimics a vaso-occlusive crisis in presentation. Alloimmunization to RBC antigens can be a serious complication of transfusion, which is of particular interest in individuals with SCD, as the occurrence rate is higher in this population. This complication represents a secondary immunological phenomenon that typically arises after the emergence of an alloantibody to which the patient had been previously sensitized to. CASE REPORT Here, we report 2 cases of delayed hemolytic transfusion reaction (DHTR) in which the patients showed evidence of alloimmunization from previous blood transfusions. The patients were managed with a variety of medications, including supportive treatments, utilization of immunosuppressive agents, and enhancement of erythropoiesis. Both patients had evidence of clinical and laboratory improvement following the management. CONCLUSIONS DHTR is considered one of the most deleterious complications of transfusion in SCD patients. The diagnosis and management of DHTR is very challenging, especially because it can present differently in this population. A high index of clinical suspicion is needed in addition to the laboratory criteria.

Delayed presentation of massive haemoptysis from aortic aneurysm after aortic coarctation repair (a case report).

INTRODUCTION: Massive haemoptysis refers to coughing and losing a huge amount of blood in a 24-hour period. It's a life-threatening condition with high mortality rate. CASE PRESENTATION: We report a rare case of massive haemoptysis in a 60-year-old female patient who had aortic coarctation repair 30 years ago. Her Computed tomography (CT) angiography showed huge aneurysmal dilatation and dissection of the descending thoracic aorta at the site of the repair. Thoracic endovascular aortic repair (TEVAR) was done, but the patient had recurrent massive haemoptysis due to extension of the aneurysm to the aortic arch. The patient then underwent one stage surgical right to left carotid artery shunt followed by TEVAR to the aortic arch covering the left common carotid artery. The procedure was successful, and haemoptysis was controlled without any complications. DISCUSSION: In this case the high index of suspicion for thoracic aortic aneurysm in patients presenting with haemoptysis and prior history of coarctation repair were demonstrated. CONCLUSION: massive haemoptysis in patients who had aortic coarctation repair is an alarming sign, and surgical intervention is required. TEVAR has become one of the best approaches for managing aortic aneurysm and has replaced open repair.

Gene therapy for spinal muscular atrophy: the Qatari experience.

Spinal muscular atrophy (SMA) is an autosomal recessive neuromuscular disorder characterized by hypotonia, progressive muscle weakness, and wasting. Onasemnogene abeparvovec (Zolgensma®) is a novel gene therapy medicine, FDA-approved in May 2019 for the treatment of SMA. This study aimed to describe Qatari experience with onasemnogene abeparvovec by reviewing the clinical outcomes of 9 SMA children (7 SMA type 1 and 2 with SMA type 2) aged 4‒23 months treated between November 2019 and July 2020. Children <2 years with 5q SMA with a bi-allelic mutation in the SMN1 gene were eligible for gene therapy. Liver function (aspartate aminotransferase [AST], alanine aminotransferase [ALT], and total bilirubin), platelet count, coagulation profile, troponin-I levels, and motor scores (Children's Hospital of Philadelphia Infant Test of Neuromuscular Disorders [CHOP INTEND]), were regularly monitored following gene therapy. All patients experienced elevated AST or ALT, two experienced high prothrombin time, and one experienced elevated bilirubin; all of these patients were asymptomatic. Furthermore, one event of vomiting after infusion was reported in one patient. Significant improvements in CHOP INTEND scores were observed following therapy. This study describes the short-term outcomes and safety of onasemnogene abeparvovec, which is well tolerated and shows promise for early efficacy.

DNA Based Vaccine Expressing SARS-CoV-2 Spike-CD40L Fusion Protein Confers Protection Against Challenge in a Syrian Hamster Model.

SARS-CoV-2 infections present a tremendous threat to public health. Safe and efficacious vaccines are the most effective means in preventing the infections. A variety of vaccines have demonstrated excellent efficacy and safety around the globe. Yet, development of alternative forms of vaccines remains beneficial, particularly those with simpler production processes, less stringent storage conditions, and the capability of being used in heterologous prime/boost regimens which have shown improved efficacy against many diseases. Here we reported a novel DNA vaccine comprised of the SARS-CoV-2 spike protein fused with CD40 ligand (CD40L) serving as both a targeting ligand and molecular adjuvant. A single intramuscular injection in Syrian hamsters induced significant neutralizing antibodies 3-weeks after vaccination, with a boost substantially improving immune responses. Moreover, the vaccine also reduced weight loss and suppressed viral replication in the lungs and nasal turbinates of challenged animals. Finally, the incorporation of CD40L into the DNA vaccine was shown to reduce lung pathology more effectively than the DNA vaccine devoid of CD40L. These results collectively indicate that this DNA vaccine candidate could be further explored because of its efficacy and known safety profile.

Early Humoral Response Correlates with Disease Severity and Outcomes in COVID-19 Patients.

The Coronavirus Disease 2019 (COVID-19), caused by SARS-CoV-2, continues to spread globally with significantly high morbidity and mortality rates. Antigen-specific responses are of unquestionable value for clinical management of COVID-19 patients. Here, we investigated the kinetics of IgM, IgG against the spike (S) and nucleoproteins (N) proteins and their neutralizing capabilities in hospitalized COVID-19 patients with different disease presentations (i.e., mild, moderate or severe), need for intensive care units (ICU) admission or outcomes (i.e., survival vs death). We show that SARS-CoV-2 specific IgG, IgM and neutralizing antibodies (nAbs) were readily detectable in almost all COVID-19 patients with various clinical presentations. Interestingly, significantly higher levels of nAbs as well as anti-S1 and -N IgG and IgM antibodies were found in patients with more severe symptoms, patients requiring admission to ICU or those with fatal outcomes. More importantly, early after symptoms onset, we found that the levels of anti-N antibodies correlated strongly with disease severity. Collectively, these findings provide new insights into the kinetics of antibody responses in COVID-19 patients with different disease severity.

SARS-CoV-2 S1 and N-based serological assays reveal rapid seroconversion and induction of specific antibody response in COVID-19 patients.

As the Coronavirus Disease 2019 (COVID-19), which is caused by the novel SARS-CoV-2, continues to spread rapidly around the world, there is a need for well validated serological assays that allow the detection of viral specific antibody responses in COVID-19 patients or recovered individuals. In this study, we established and used multiple indirect Enzyme Linked Immunosorbent Assay (ELISA)-based serological assays to study the antibody response in COVID-19 patients. In order to validate the assays we determined the cut off values, sensitivity and specificity of the assays using sera collected from pre-pandemic healthy controls, COVID-19 patients at different time points after disease-onset, and seropositive sera to other human coronaviruses (CoVs). The developed SARS-CoV-2 S1 subunit of the spike glycoprotein and nucleocapsid (N)-based ELISAs not only showed high specificity and sensitivity but also did not show any cross-reactivity with other CoVs. We also show that all RT-PCR confirmed COVID-19 patients tested in our study developed both virus specific IgM and IgG antibodies as early as week one after disease onset. Our data also suggest that the inclusion of both S1 and N in serological testing would capture as many potential SARS-CoV-2 positive cases as possible than using any of them alone. This is specifically important for tracing contacts and cases and conducting large-scale epidemiological studies to understand the true extent of virus spread in populations.

Cancer genetics program: Follow-up on clinical genetics and genomic medicine in Qatar.

This article presents an overview of the cancer genetics program in Qatar. In addition to summarizing clinical, research, educational, and other aspects, data related to testing outcomes (over the course of approximately 5.5 years) are presented.

Depression, Hopelessness and Social Support among Breast Cancer Patients: in Highly Endogamous Population

Aim: The aim of this study was to assess the relationship between different demographic variables, hopelessness, depression and social support of Breast cancer patients in Qatari's population. Design: This is an observational cohort hospital based study. Subjects and Methods: The study included 678 breast cancer patients. The questionnaires included a demographic questionnaire, the Beck Hopelessness Scale (BHS), Back Depression Scale (BDS) and Multidimensional Scale of Perceived Social Support (MSPSS). The demographic questionnaire was used to assess patients' basic information including gender, age, marital status, education, family size, and place of residence. Medical information regarding cancer stage, the time passed since diagnosis, treatment, and duration of disease were recorded. Results: The mean age of the studied women was 47.7±10.2 years. Among the studied patients, 34.7% were Qataris and 65.3% were Arab expatriates. Nearly 39.2% of the patients were in pre-menopausal status and 60.8% in post-menopausal status. 86.1% of women were married. 14.6% were illiterate women, 20.9% were university graduates and 37.2% were housewives. Smoking habit was less common in studied Arab women (9.1%), but, sheesha smoking was more common, 17.7%. Daily physical activity indicated 25.7% were walking 30 minutes per-day and 14% were walking 60 minutes per day. 30.4% of them had consanguineous parents. Breast feeding was practiced among 67.7% of women and over 73% were considered overweight and obese. Furthermore, over 75% of breast cancer women were at the Stage 3 (40.9%) and Stage 4 (35.8%) of cancer. The percentage of patients who underwent mastectomy and lumpectomy were 49.3 % and 50.7%, respectively. It was observed that 27.7% of BDI patients had moderate depression and 19.5% of the BDI patients had severe depression and with mean and standard deviation 25.1±7.7. Also, the mean and SD of BDI for consanguineous has showed statistically significant 28.4±5.7 than non- consanguineous 23.2± 8.0 (p<0.001). All socio-demographic variables showed statistically significant differences with the total BHS score. The highest score belongs to the family sub-dimension. Conclusion: The present study indicates that hopelessness of the patients with breast cancer decreased with the increase in their social support. Therefore, activating patient social support systems is of importance in increasing their levels of hope. The present study revealed the coexistence of the socio-demographic, physical, psychological, and cognitive problems faced by patients with cancer.

An assessment of reliability and validity of the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire C30 among breast cancer patients in Qatar.

INTRODUCTION: Breast cancer has been the most common cancer type that affects women worldwide and subsequent treatment is often associated with considerable psychological and quality of life (QoL). AIM: This study aimed to assess psychometric properties of the Arabic version of the European Organization for Research and Treatment of Cancer (EORTC) general QoL questionnaire (QLQ-C30) for breast cancer patients in Qatar. MATERIALS AND METHODS: This is a cross-sectional hospital-based study conducted on 678 breast cancer patients using Arabic version of the EORTC QLQ-C30 tool. RESULTS: The mean age of women was 47.7 ± 10.2 years and 33.4% of women had consanguineous parents. Six subscales out of the nine met the standards of reliability with coefficients ranging from 0.55 to 0.89. The mean score of all functioning scales was high >55. Advanced breast cancer stages of III-IV had higher symptomatic scores significantly than those in early stages for the physical function, cognitive, fatigue, insomnia, appetite loss, constipation, and financial difficulties. Correlation coefficients between each item ranged from -0.113 to 0.960, and item 21 (tense) and item 23 (irritable) had strongest negative correlations with their corresponding emotional functioning subscale, whereas items 29 (physical condition) and 30 (overall QoL) had the strongest positive correlation with Global Health/QoL subscale. Item 6 (limited work) showed a higher correlation with fatigue (r = 0.749). Likewise, item 19 (pain interfered with daily activities) of the pain subscale had higher correlations with physical functioning, role functioning, and fatigue subscales. CONCLUSION: Qatari Arabic version of the EORTC QLQ-C30 showed acceptable psychometric properties, which is a reliable and valid instrument, that can be used by oncologists.
