Clinical presentation,management, screening and surveillance for colorectal cancer during the COVID-19 pandemic

Management of colorectal cancer (CRC) was severely affected by the changes implemented during the pandemic, and this resulted in delayed elective presentation, increased emergency presentation, reduced screening and delayed definitive therapy. This review was conducted to analyze the impact of the coronavirus disease 2019 (COVID-19) pandemic on management of CRC and to identify the changes made in order to adapt to the pandemic. We performed a literature search in PubMed, Medline, Index Medicus, EMBASE, SCOPUS, Reference Citation Analysis (https://www.referencecitationanalysis.com/) and Google Scholar using the following keywords in various combinations: Colorectal cancer, elective surgery, emergency surgery, stage upgrading, screening, surveillance and the COVID-19 pandemic. Only studies published in English were included. To curtail the spread of COVID-19 infection, there were modifications made in the management of CRC. Screening was limited to high risk individuals, and the screening tests of choice during the pandemic were fecal occult blood test, fecal immunochemical test and stool DNA testing. The use of capsule colonoscopy and open access colonoscopy was also encouraged. Blood-based tests like serum methylated septin 9 were also encouraged for screening of CRC during the pandemic. The presentation of CRC was also affected by the pandemic with more patients presenting with emergencies like obstruction and perforation. Stage migration was also observed during the pandemic with more patients presenting with more advanced tumors. The operative therapy of CRC was altered by the pandemic as more emergencies surgeries were done, which may require exteriorization by stoma. This was to reduce the morbidity associated with anastomosis and encourage early discharge from the hospital. There was also an initial reduction in laparoscopic surgical procedures due to the fear of aerosols and COVID-19 infection. As we gradually come out of the pandemic, we should remember the lessons learned and continue to apply them even after the pandemic passes.

The impact of cytogenetic risk on the outcomes of allogeneic hematopoietic cell transplantation in patients with relapsed/refractory acute myeloid leukemia: On behalf of the acute leukemia working party (ALWP) of the European group for blood and marrow transplantation (EBMT)

Karyotypic analysis at time of diagnosis has an important value in determining initial response to treatment, remission duration and overall survival (OS) in acute myeloid leukemia (AML). Less is known about its value before allogeneic hematopoietic cell transplantation (allo‐HCT) in patients transplanted with active disease, either relapsed or primary refractory (Rel‐Ref) AML. We explored the impact of cytogenetic risk (stratification according to MRC‐UK) in 2089 patients with either Ref (n = 972) or Rel AML (n = 1117) transplanted during the period 2000‐2017. Overall, 154 patients had a favorable risk, 1283 had an intermediate risk and 652 had an adverse cytogenetic risk. Median follow‐up was 49 months. Compared to the favorable risk group, intermediate and adverse risk patients were associated with worse leukemia‐free survival and OS and also with a higher incidence of relapse. In a subgroup analysis of patients in the intermediate risk group harboring Fms‐like tyrosine kinase 3‐internal tandem duplication (FLT3‐ITD), this remained an important prognostic factor, being associated with worse outcomes. When analyzing patients according to the intensity of the conditioning regimen, no differences were observed for the main transplant outcomes. In conclusion, in patients diagnosed with AML and transplanted with active disease, karyotype remains an important prognostic factor, allowing splitting patients into different risk groups according to their cytogenetics. Similarly, FLT3‐ITD mutation also remains a negative prognostic factor in this population.     

An assessment of cerebral venous thrombosis risk factors and associated clinical outcomes in Jazan region,Saudi Arabia

Objectives:To assess cerebral venous thrombosis risk factors, and associated clinical outcomes in Jazan region, Kingdom of Saudi Arabia.Methods:This study is a retrospective review of the medical records of patients diagnosed with cerebral venous thrombosis and admitted to King Fahad Central Hospital in Jazan between 2010 and 2019. Data concerning socio-demographics, clinical features, risk factors, laboratory, and imaging investigations were retrieved. Furthermore, data about cases management, and outcomes, including death, were collected and analysed.Results:A total of 51 medical records were identified. The majority of the patients were females (68.6%), and the mean age of the patients was 33.3 years, of which three patients were under 18 years old. The most frequently recorded symptom was headache (76.5%), followed by seizure (45.1%). The most commonly recorded risk factor was protein S deficiency (57%), followed by anaemia (51%). Venous infarction and haemorrhage were the most common acute complications (13.7%). The majority of the patients had a favourable prognosis where only 27.5% recovered with disability and only one patient died due to the disease.Conclusion:Clinical presentation of cerebral venous thrombosis in Jazan region is similar to other local and international studies. However, anaemia was recorded as a main risk factor for the disease, which might require further investigation to assess the possible association between prevalence of anaemia in Jazan region and the incidence of cerebral venous thrombosis.

Cerebral venous thrombosis (CVT) is a rare form of cerebrovascular disease in comparison with arterial stroke. CVT cases represent approximately 0.5-1% of all types of stroke which mainly occur in young and middle-aged adults.1 The data concerning the global epidemiology of CVT is currently limited.2 However, the incidence of CVT has been reported to vary between countries where the incidence might be higher as in Asian and the Middle Eastern countries in comparison to Australia and European countries.3According to a recent study conducted in Australia, the incidence of CVT was reported to reach 15.7 per 1,000,000 persons on a yearly basis. The incidence was higher among women and among those between 31-50 years old.4 In the Middle East, an Iranian study looked at the frequency of CVT between 2001 and 2004, and the annual frequency of CVT was 12.3 per one million.5 An older study, conducted in the city of Riyadh in Saudi Arabia between 1985 and 1994, identified 40 cases of CVT. Those identified were aged between 16 and 40.6 In addition, in a more recent study conducted in Jeddah and Al-Baha between 1990 and 2010, the number of detected cases of CVT was 111 where 19 of these were detected among children.7The CVT occurs when a thrombus develops as a result of a disturbance of the balance between the process of prothrombosis and thrombolysis.8,9 Risk factors for CVT can be categorised into transient and permanent risk factors. Permanent risk factors are hereditary thrombophilia, systemic diseases or miscellaneous factors, such as obesity. Transient risk factors can be subcategorised into sex-specific, iatrogenic, or miscellaneous risk factors, such as infection, head trauma or anaemia.8 The prevalence of CVT risk factors differs between countries. Infection, pregnancy, post-partum period, and dehydration have been reported to be more common in Asia and the Middle Eastern countries in comparison to European countries.8Patients with CVT exhibit variable clinical manifestations and complications, some of which can be life threatening. The most common clinical presentation is a headache, while some patients exhibit other signs and symptoms, such as seizure, decreased level of consciousness, vomiting, focal neurological deficit, or visual symptoms.8-10 Venous infarction and haemorrhage are frequently reported complications of CVT.11 Late presentation of CVT patients can increase the risk of disability and death. The mortality rate among CVT patients has been reported to vary between 4.3% and 6.8%.12Since CVT risk factors and vulnerable groups can vary between different populations, assessment of the distribution of risk factors among local populations can be clinically valuable. Studies assessing CVT prevalence and associated risk factors and clinical outcomes in Saudi populations are currently limited. Furthermore, data about CVT in Jazan region is currently lacking. This investigation aims to identify cases diagnosed with CVT in Jazan region and to evaluate the risk factors and associated clinical outcomes.

The influence of polymorphisms in the drug transporter,ABCB1 on the toxicity of glucocorticoids in Saudi children with acute lymphoblastic leukaemia

Background

Glucocorticoids play essential roles in the treatment of childhood acute lymphoblastic leukaemia (ALL); however, treatment with these agents can result in severe side-effects. This study, the first of its kind in a Saudi population, investigates associations of ABCB1 gene polymorphisms (pharmacodynamics and pharmacokinetic) with the development of toxicity and side effects (glucose abnormality, liver toxicity and infection) in a small population of Saudi children with ALL.
