Abstract

Background
The purpose of this study was to assess the role of hypophosphatemia in major clinical outcomes of patients treated with low- or high-intensity continuous renal replacement therapy (CRRT).

Methods
We performed a retrospective analysis of data collected from 492 patients. We divided patients into two CRRT groups based on treatment intensity (greater than or equal to or less than 40 mL/kg/hour of effluent generation) and measured serum phosphate level daily during CRRT.

Results
We obtained a total of 1,440 phosphate measurements on days 0, 1, and 2 and identified 39 patients (7.9%), 74 patients (15.0%), and 114 patients (23.1%) with hypophosphatemia on each of these respective days. In patients treated with low-intensity CRRT, there were 23 episodes of hypophosphatemia/1,000 patient days, compared with 83 episodes/1,000 patient days in patients who received high-intensity CRRT (P < 0.01). Multiple Cox proportional hazards analysis showed that Acute Physiology and Chronic Health Evaluation (APACHE) III score, utilization of vasoactive drugs, and arterial pH on the second day of CRRT were significant predictors of mortality, while serum phosphate level was not a significant contributor to mortality. Conclusion APACHE score, use of vasoactive drugs, and arterial pH on the second CRRT day were identified as significant predictors of mortality. Hypophosphatemia might not be a major risk factor of increased mortality in patients treated with CRRT.

Abstract

Background:
Obstructive sleep apnea is a prevalent disorder associated with cognitive dysfunction and cardiovascular and metabolic morbidity and is characterized by recurrent episodes of hypoxia during sleep. Bone marrow-derived very small embryonic-like (VSEL) pluripotent stem cells represent a recruitable pool that may play an important role in organ repair after injury. We hypothesized that exposure to intermittent hypoxia (IH) can mobilize VSELs from the bone marrow (BM) to peripheral blood (PB) in mice and can activate distinct transcriptional programs.

Methods:
Adult mice were exposed to IH or normoxia for 48 hours. VSELs were sorted from BM and PB using flow cytometry. Plasma levels of stem cell chemokines, stromal cell derived factor-1 (SDF-1), hepatocyte growth factor (HGF), and leukemia inhibitory factor (LIF) were measured. Transcriptional profiling of VSELs was performed, and differentially expressed genes were mapped to enriched functional categories and genetic networks.

Results:
Exposure to IH elicited migration of VSELs from BM to PB and elevations in plasma levels of chemokines. More than 1100 unique genes were differentially expressed in VSELs in response to IH. Gene Ontology and network analysis revealed the activation of organ-specific developmental programs among these genes.

Conclusions:
Exposure to IH mobilizes VSELs from the BM to PB and activates distinct transcriptional programs in VSELs that are enriched in developmental pathways, including central nervous system development and angiogenesis. Thus, VSELs may serve as a reserve mobile pool of pluripotent stem cells that can be recruited into PB and may play an important role in promoting end-organ repair during IH.

Abstract

Deserts, even those at tropical latitudes, often have strikingly low levels of plant diversity, particularly within genera. One remarkable exception to this pattern is the genus Petalidium (Acanthaceae), in which 37 of 40 named species occupy one of the driest environments on Earth, the Namib Desert of Namibia and neighboring Angola. To contribute to understanding this enigmatic diversity, we generated RADseq data for 47 accessions of Petalidium representing 22 species. We explored the impacts of 18 different combinations of assembly parameters in de novo assembly of the data across nine levels of missing data plus a best practice assembly using a reference Acanthaceae genome for a total of 171 sequence datasets assembled. RADseq data assembled at several thresholds of missing data, including 90% missing data, yielded phylogenetic hypotheses of Petalidium that were confidently and nearly fully resolved, which is notable given that divergence time analyses suggest a crown age for African species of 3.6-1.4 Ma. De novo assembly of our data yielded the most strongly supported and well?resolved topologies; in contrast, reference?based assembly performed poorly, perhaps due in part to moderate phylogenetic divergence between the reference genome, Ruellia speciosa, and the ingroup. Overall, we found that Petalidium, despite the harshness of the environment in which species occur, shows a net diversification rate (0.8-2.1 species per my) on par with those of diverse genera in tropical, Mediterranean, and alpine environments.
