Abstract
Objectives This study aimed to explore real-world data on the long-term survival of cancer patients using historical records from the Surveillance, Epidemiology, and End Results (SEER) Programme. Long-term survival is an important endpoint in the management of different malignancies. It is rarely assessed due to the unfeasibility of follow-up for a long duration of time. Besides reporting the five-year relative survival, the 10- and 20-year survival rates for different types of cancers were analysed. Additionally, survival trends as a function of time, age and tumour type were reviewed and reported. Methods The study used SEER*Stat (Version 8.3.6.1) for data acquisition from the SEER 9 Regs (November 2019) database. Data from patients diagnosed with cancer between 1975 and 2014 were retrieved and included in the analysis. Results For patients diagnosed with any malignant disease (N = 4,412,024), there was a significant increase in median overall survival over time (P <0.001). The 20-, 10-, and 5-year survival rates were higher in solid tumours compared to haematological malignancies (50.8% versus 38%; 57% versus 47.4%; and 62.2% versus 57.4%, respectively). The highest 20-year relative survival rates were observed in thyroid cancer (95.2%), germ cell and trophoblastic neoplasms (90.3%), melanoma (86.8%), Wilms' tumour (86.2%) and prostate cancer (83.5%). Conclusion Long-term follow-up data were suggestive of high 20-year relative survival rates for most tumour types. Relative survival showed an improving trend over time, especially in solid tumours.

Abstract
BACKGROUND Medical undergraduates' (UGs) involvement in research activities is thought to be mutually beneficial to students, their mentors and the scholarly productivity of their universities. However, most evidence in favor of such assumption relies on subjective measures such as the self-reported gains in skills or knowledge rather than robust objective estimates for assessing impact. AIM We aimed to objectively track and describe publications with UG co-authors-their proportion to the total publication output of world's top universities, their characteristics and their potential impact on biomedical literature. METHODS We contacted the corresponding authors of the 2013's Medline-indexed publications affiliated to world's top 10 universities to investigate if any of their co-authors was an UG. Articles with UG co-authors were further assessed to determine, along with other variables: the type of study design, field of the article, publishing journal and its impact factor (IF), and number of received citations. RESULTS Out of 25 152 publications, 2537 articles (10.1%) contained at least one UG co-author who was the first author in 635 papers (25%). Articles with UG co-authors were published in 1114 journals with a median IF of 3.661. Most UGs' co-authored publications (82.7%, n = 2098) were cited at least once within 1 year, for a median of three citations per article. CONCLUSION UGs contributed to one in every 10 publications affiliated to top universities. Their papers were published in journals with good IFs and received a fair number of citations, which would reflect the relatively good quality and impact of these articles.

Abstract
A malaria vaccine targeting Plasmodium falciparum remains a strategic goal for malaria control. If a polyvalent vaccine is to be developed, its subunits would probably be chosen based on immunogenicity (concentration of elicited antibodies) and associations of selected antigens with protection. We propose an additional possible selection criterion for the inclusion of subunit antigens; that is, coordination between elicited antibodies. For the quantitative estimation of this coordination, we developed a malaria serological map (MSM). Construction of the MSM was based on three categories of variables: (i) malaria antigens, (ii) total IgG and IgG subclasses, (iii) different sources of plasma. To validate the MSM, in this study, we used four malaria antigens (AMA1, MSP2-3D7, MSP2-FC27 and Pf332-C231) and re-grouped the plasma samples into five pairs of subsets based on age, gender, residence, HbAS and malaria morbidity in 9 years. The plasma total IgG and IgG subclasses to the test antigens were measured, and the whole material was used for the MSM construction. Most of the variables in the MSM were previously tested and their associations with malaria morbidity are known. The coordination of response to each antigens pair in the MSM was quantified as the correlation rate (CR = overall number of significant correlations/total number of correlations × 100 %). Unexpectedly, the results showed that low CRs were mostly associated with variables linked with malaria protection and the antigen eliciting the least CRs was the one associated with protection. The MSM is, thus, of potential value for vaccine design and understanding of malaria natural immunity.

Abstract
Schistosomiasis is a widespread helminthic disease. Treatment of schistosomiasis is based on chemotherapy with praziquantel, which is the drug of choice. Since resistance to praziquantel has been demonstrated, alternative drugs must be considered. Myrrh is an oleo-gum resin from the stem of the plant Commiphora molmol. This study was carried out on 204 patients with schistosomiasis. The drug was given at a dose of 10 mg/kg of body weight/day for three days, and induced a cure rate of 91.7%. Re-treatment of cases who did not respond with a dose of 10 mg/kg of body weight/day for six days gave a cure rate of 76.5%, increasing the overall cure rate to 98.09%. The drug was well tolerated, and side effects were mild and transient. Twenty cases provided biopsy specimens six months after treatment and none of them showed living ova.

Abstract
BACKGROUND/AIMS Since pharmacotherapy of portal hypertension has always been a subject of wide interest, we decided to study the effects of different angiotensin-converting enzyme inhibitors and endoscopic sclerotherapy on portal hemodynamics in patients with portal hypertension and bleeding esophageal varices. METHODOLOGY The study included 72 patients with portal hypertension divided into 6 equal groups. Endoscopic sclerotherapy was done to all patients every 2 weeks for 3 months. In addition, the first 5 groups of patients were maintained on angiotensin-converting enzyme inhibitors for 3 months as follows: group I on perindopril, II on ramipril, III on fosinopril, IV on lisinopril and V on captopril. Portal hemodynamics were determined before and after therapy (using an ultrasonic duplex system). New Doppler portal indices were derived and portal vein kinetic pressure was estimated for the first time by using data derived from the ultrasonic duplex system. RESULTS 1) Short-term endoscopic sclerotherapy alone resulted in significant elevation of portal vein kinetic pressure, wall stress index and flow volume (P < 0.01) and non-significant increase in the total portal circulation resistance index (P > 0.05) and significantly decreased portal vein compliance and distensibility indices (P < 0.05); 2) Angiotensin-converting enzyme inhibitors reduced the maximum and average portal velocities, the portal flow volume, total portal circulation resistance index and increased portal vein compliance and distensibility indices, hence they reduced the portal vein kinetic pressure significantly in group IV (P < 0.05 for the flow volume and P < 0.01 for other indices); 3) The only side effect encountered was allergic cough (in 8.33% of patients). No effects were noticed on the pulse, systolic, diastolic or mean blood pressures or Child-Pugh Score of liver disease. CONCLUSIONS 1) Angiotensin-converting enzyme inhibitors when added to endoscopic sclerotherapy can ameliorate the effects of the latter on portal hemodynamics in patients with portal hypertension; 2) Portal vein kinetic pressure, total portal circulation resistance index, portal vein wall stress index, compliance and distensibility indices are new Doppler portal indices that proved to be of value in the follow-up of patients with portal hypertension under sclerotherapy alone or in conjunction with pharmacotherapy; 3) Angiotensin-converting enzyme inhibitors are safe drugs that can be used for portal decompression with endoscopic sclerotherapy. Their use as sole portal anti-hypertensive agents still awaits further studies.
