The article in Respirology addresses the challenges facing healthcare in Sudan due to the ongoing conflict, particularly focusing on the impact on tuberculosis (TB) and mental health. The conflict has exacerbated the burden of TB, leading to treatment interruptions and an increased risk of multidrug-resistant TB. The lack of healthcare access in overcrowded camps has further fueled the spread of TB, while the mental health impact of the conflict, including anxiety and depression, is often overlooked but critical for holistic crisis response. Immediate action is needed to address both the physical and mental health needs of those affected in Sudan. [Extracted from the article]

Hepatobiliary surgery through laparoscopic approach is becoming a routine. Knowledge of extrahepatic arterial tree is essential for surgical and imaging procedures. Anatomical complexity is expected since the liver is developed by mergingof lobules with its separate blood supply. This makes a wide range of variations in the pattern of vascular arrangement and so reinforces the need for an accurate understanding of full spectrum of variations. This study aimed to investigate the variations in origin and distribution of extrahepatic arterial supply. Fifty volunteers (32 males and 18 females) aged 20–70 years were randomly recruited from the department of CT scan in Al Amal Hospital, Khartoum North, Sudan. The patients were already candidates for CT angiography with contrast for conditions other than hepatobiliary diseases. The reported data is related to those who accepted to participate in the study. Patients with history of hepatobiliary disease were excluded. 3D views of the scans were treated and the extrahepatic arterial tree was traced in a computer-based software. Key findings suggest that Michel’s classification was considered the standard template for description – 76% of them showed Michel’s type I classification. Types III and V constituted about 2%. About 4% of the cases were represented by types VI and IX. Other types of variations constituted about 12%. To conclude, although type I classification which describes the textbook pattern of hepatic artery distribution was significantly detected among the Sudanese population, other variants were to be considered since they are related to major arteries like aorta and superior mesenteric.

The recently cloned glucose regulated protein 78 (GRP78) of Leishmania donovani has been suggested as a new and promising Leishmania vaccine candidate. We assessed antibody and T-cell reactivity to GRP78 in an enzyme-linked immunosorbent assay (ELISA) and in lymphoproliferative assays. Serological evaluation of plasma samples obtained in Sudan revealed that 89% of patients with visceral leishmaniasis (VL), 78% with post kala-azar dermal leishmaniasis (PKDL), and 85% with cutaneous leishmaniasis (CL) had antibody reactivity to this Leishmania antigen. Plasma from healthy Sudanese individuals living in an area endemic for malaria but free of leishmaniasis and plasma from healthy Danes was negative in the assay. GRP78 antibody was detected in 10% and 5% of plasma samples from Sudanese and Ghanaian malaria patients, respectively, whereas 35% of plasma samples from otherwise healthy Sudanese individuals with a positive leishmanin skin test showed antibody reactivity to recombinant GRP78 (rGRP78). In lymphoproliferative assays, 9 of 13 isolates of peripheral blood mononuclear cells (PBMC) from individuals previously infected with L. donovani and one of three individuals previously infected with L. major showed a response to rGRP78, whereas PBMC isolates from Danish control individuals did not respond. These findings, in addition to our previous observations in experimental CL (Jensen et al. 2001), confirm GRP78 as a possible vaccine antigen.
