Patients newly diagnosed with metastatic pancreatic ductal adenocarcinoma generally have poor survival, with heterogeneous rates of progression. Biomarkers that could predict progression and/or survival would help inform patients and providers as they make care decisions. In a previous retrospective study, we discovered that circulating thrombospondin-2 (THBS2) could, in combination with CA19-9, better distinguish patients with PDAC versus healthy controls. Here we evaluated whether THBS2 levels, previously not known to be prognostic, were associated with outcome in 68 patients at time of diagnosis of metastatic PDAC. Specifically, we interrogated the association of THBS2 level, alone or in combination with CA19-9, with progression by 90 days and/or survival to 180 days. The results indicate that elevated THBS2 levels alone, at the time of a metastatic PDAC diagnosis, can identify patients with a shorter time to death and thus help patients and providers when planning treatment.

Collective migration of cancer cells is often interpreted using concepts derived from the physics of active matter, but the experimental evidence is mostly restricted to observations made in vitro. Here, we study collective invasion of metastatic cancer cells injected into the mouse deep dermis using intravital multiphoton microscopy combined with a skin window technique and three-dimensional quantitative image analysis. We observe a multicellular but low-cohesive migration mode characterized by rotational patterns which self-organize into antiparallel persistent tracks with orientational nematic order.

Significance: Epidemiological information about the epiretinal membrane is important for better clinical management and understanding of the nature and burden of this disease. There are some gaps in our understanding of the epidemiology of epiretinal membranes, particularly in Africa and the Middle East.
Purpose: This study aimed to determine the prevalence and risk factors of epiretinal membrane using spectral-domain optical coherence tomography (OCT) in an Iranian elderly population.

Many visualisations used in the climate communication field aim to present the scientific models of climate change to the public. However, relatively little research has been conducted on how such data are visually processed, particularly from a behavioural science perspective. This study examines trends in visual attention to climate change predictions in world maps using mobile eye-tracking while participants engage with the visualisations.

Rationale: The occurrence of refractory small cell lung cancer (rSCLC) with pancreatic metastasis is a relatively rare clinical condition, which is typically accompanied by a poor prognosis and rapid disease progression.
Patient Concerns: A 65-year-old male farmer from China was diagnosed with limited-stage small cell lung cancer (SCLC) 8 months ago. Following 6 cycles of EP chemotherapy, the patient's tumor response showed partial relief.
Disseminated organ and tissue infection secondary to carbapenem-resistant Klebsiella pneumoniae bloodstream infection for acute lymphoblastic leukemia treated with ceftazidime-avibactam: Two case reports.

Department of Hematology, Tongde Hospital of Zhejiang Province, Hangzhou, P.R. China.
Rationale: Carbapenem-resistant Klebsiella pneumoniae (CRKP) bloodstream infections are a severe complication resulting from granulocyte deficiency following chemotherapy for hematologic malignancies and have a high mortality rate. However, reports of disseminated organ infections secondary to bloodstream infections are rare.
Patient Concerns And Diagnoses: We report 2 cases of patients with acute lymphoblastic leukemia who both developed CRKP bloodstream infections during the granulocyte deficiency stage following chemotherapy, with 1 case of secondary bacterial liver abscess and 1 case of secondary septic arthritis.
