Graft-versus-host disease (GVHD) prophylaxis based on post-transplant cyclophosphamide (PTCy) or antithymocyte globulin (ATG) is widely used in allogeneic hematopoietic stem cell transplantations (allo-HCT). The differential impacts of PTCy and ATG on transplantation outcomes are not well characterized. Here we report a meta-analysis of PTCy versus ATG in allo-HCT. Ten studies were eligible, and a total of 1871 patients were included. The incidence of II-IV aGVHD, III-IV aGVHD, and NRM were significantly lower in PTCy arm (HR = 0.63, 95% CI 0.45-0.89; HR = 0.35, 95% CI 0.16-0.77; HR = 0.59, 95% CI 0.48-0.73). PTCy was associated with a better OS and PFS (HR = 0.62, 95% CI = 0.53-0.73; HR = 0.76, 95% CI 0.62-0.93). The relapse rate and cGVHD incidence were not significantly different between PTCy and ATG (HR = 0.85, 95% CI 0.68-1.07; HR = 0.65, 95% CI 0.38-1.12). Thus, compared with ATG, PTCy has a better aGVHD control and OS benefit, without increasing relapse risk, which needs further validation in prospective randomized trials.Epithelioid hemangioma of the bone is a rare kind of vascular neoplasm posing a diagnostic challenge because of its ability to mimic malignant tumors. We report a case of a fast-growing, talofibular joint-involving epithelioid hemangioma, which was suspectedly initiated by vascular damage due to trauma and arthroscopy. The ankle mass appeared as a lytic lesion on the CT images and as a T1 hypo-, T2 mildly hyperintense, lobulated structure on the MRI scans. The contrast enhancement pattern was typical to vascular neoplasms. Histologically the lesion consisted of well-formed vessels lined with epithelioid cells with a slightly atypical nuclear morphology, inflammation with a significant number of eosinophils, and low mitotic rate. Immunohistochemistry analysis showed the presence of vascular markers but no rearrangements characteristic of soft tissue sarcomas were registered by the next-generation sequencing. The surgical treatment was curative. The report presents current imaging methods and summarizes the imaging findings of transarticular spreading tumors.

Correct diagnosis of the epithelioid hemangioma is essential, as the treatment of more malignant entities is substantially different. An added value of the report is that to the best of our knowledge, a transarticular spreading epithelioid hemangioma of the ankle has never been described before.<br /><br /> Multimodal therapy incorporating cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) improve survival for selected patients with colorectal peritoneal metastases (CPMs). Many countries have centralised management of these patients, aiming to improve outcomes. There is ongoing debate on the need for and complications associated with HIPEC administration. We report indications and outcomes after CRS/HIPEC treated in a national centre in the modern era.<br /><br /> A retrospective review of all CPM patients who underwent CRS and HIPEC since the initiation of an Irish national program in 2013. The primary endpoint was the overall survival associated with CRS/HIPEC.<br /><br /> During the study period (April 2013-June 2020), 123 patients proceeded to planned CRS/HIPEC for CPM. Median age was 58 (IQR 47-67) and 55 patients (44.7%) were male. In 65 patients (52.8%), CPM was synchronous. In 7/123 (5.8%), disease was unresectable. The median peritoneal cancer index (PCI) was 10 (IQR 5-17). Overall, 104/123 (84.5%) underwent a complete cytoreduction (CC0/CC1). Thirteen out of 123 (10.5%) patients also had a synchronous liver resection. Forty out of 123 (32.5%) patients had adverse pathological features (poorly differentiated or signet ring cells). The median survival in patients after CC0, CC1 and CC2/3 resection was 50, 18 and 11months respectively (*p= &lt; 0.0001, Log-rank Mantel-Cox). In total, 14/123(11.4%) had a major post-operative complication and 4/123 (3.3%) required re-operation. There was one (0.8%) post-operative death. The median length of stay was 14days (IQR 9-19).<br /><br /> This study reports encouraging outcomes in patients with CPM undergoing CRS and HIPEC, especially when complete cytoreduction is achieved.<br /><br />This study reports encouraging outcomes in patients with CPM undergoing CRS and HIPEC, especially when complete cytoreduction is achieved.In the ongoing pandemic, death statistics influence people's feelings and government policy. But when does COVID-19 qualify as the cause of death? As philosophers of medicine interested in conceptual clarification, we address the question by analyzing the World Health Organization's rules for the certification of death. We show that for COVID-19, WHO rules take into account both facts (causal chains) and values (the importance of prevention).This study is aimed at investigation of various potential contaminants (arsenic, mercury and polycyclic aromatic hydrocarbons) content in soils of different landscapes of Eastern Antarctica ice-free areas. Our data not only showed that intensive human impact might result in significant direct contamination of surrounding landforms, but also revealed a specific role of ornithogenic transport in distribution of contaminants. Analysis revealed that the contents of investigated elements were 0.100-8.055 mg kg-1 (arsenic), 0.025-0.027 mg kg-1 (mercury) in Larsemann Hills and 0.100-1.213 mg kg-1 (arsenic), 0.023-0.593 mg kg-1 (mercury) in vicinities of Mirny station and Fulmar Island. Accumulation of some elements in guano-derived and moss materials lead to higher values of other soil pollution indices at natural sites. Results of our study revealed the predominance of light molecular weight PAHs (fluorene and acenaphthylene) in studied soils. Results of our study are not completely in agreement with the idea of an practically uncontaminated Antarctic ecosystem which was previously reported for Eastern Antarctica ice-free areas. Various human activities carried out at local scale have been found to be responsible for increase of metal levels in studied Antarctic environments.
