Malunions following lower extremity fractures in veterans with a spinal cord injury/disorder.

Background: Nearly 50% of all persons with a spinal cord injury/disorder (SCI/D) will sustain an osteoporotic fracture sometime in their life, with lower extremity fractures being the most common. There are a number of complications that can occur post fracture, including fracture malunion. To date, there have been no dedicated investigations of malunions among persons with SCI/D.

Bilateral Subluxation of Microspherophakic Lens in a Child with Cohen Syndrome.

Cohen Syndrome is a rare autosomal recessive condition characterized by facial abnormalities with or without microcephaly, non-progressive intellectual delay, hypotonia, ophthalmic abnormalities, and neutropenia. Due to its low incidence and variable presentation, much about the disorder, including ophthalmic manifestations, is not fully understood. Here, we present the first documented case of a 5-year-old Amish child with Cohen Syndrome who presented with bilateral subluxation of microspherophakic lenses - rare findings themselves, let alone coexisting in a patient with a rare genetic syndrome.

Risk Factors and Consequences of Lower Extremity Fracture Nonunions in Veterans With Spinal Cord Injury.

We used Veterans Health Administration (VHA) national administrative data files to identify a cohort (fiscal years 2005-2014) of veterans with spinal cord injuries and disorders (SCID) to determine risk factors for and consequences of lower extremity fracture nonunions. Odds ratios (OR) for fracture nonunion were computed using multivariable-adjusted logistic regression models. We identified three risk factors for nonunion: (i) older age (OR = 2.

Nicotinamide-Ponatinib Analogues as Potent Anti-CML and Anti-AML Compounds.

Ponatinib is a multikinase inhibitor that is used to treat chronic myeloid leukemia patients harboring mutated ABL1(T315I) kinase. Due to the potent inhibition of FLT3, RET, and fibroblast growth factor receptors (FGFRs), it is also being evaluated against acute myeloid leukemia (AML), biliary, and lung cancers. The multikinase inhibition profile of ponatinib may also account for its toxicity, thus analogs with improved kinase selectivity or different kinase inhibition profiles could be better tolerated.

Epiploic appendagitis: A rare cause of acute abdomen.

Epiploic appendagitis is a rare cause of acute abdomen that often manifests with acute onset of pain in the left or right lower quadrant. Its symptoms can mimic and be mistaken for acute diverticulitis, appendicitis, or omental infarction. In this case report, we discuss a 65-year-old woman who presented with sharp right upper and lower quadrant abdominal pain, for which she had an emergent abdominal computed tomography (CT) scan.

Functional compensation between hematopoietic stem cell clones .

In most organ systems, regeneration is a coordinated effort that involves many stem cells, but little is known about whether and how individual stem cells compensate for the differentiation deficiencies of other stem cells. Functional compensation is critically important during disease progression and treatment. Here, we show how individual hematopoietic stem cell (HSC) clones heterogeneously compensate for the lymphopoietic deficiencies of other HSCs in a mouse.

Transplantation Dose Alters the Differentiation Program of Hematopoietic Stem Cells.

Hematopoietic stem cell (HSC) transplantation is the most prevalent stem cell therapy, but it remains a risky procedure. To improve this treatment, it is important to understand how transplanted stem cells rebuild the blood and immune systems and how this process is impacted by transplantation variables such as the HSC dose. Here, we find that, in the long term following transplantation, 70%-80% of donor-HSC-derived clones do not produce all measured blood cell types.

Nonadherence to Antihypertensive Medication Among Hypertensive Adults in the United States─HealthStyles, 2010.

Nonadherence, or not taking medications as prescribed, to antihypertensive medications has been associated with uncontrolled hypertension. The authors analyzed data from HealthStyles 2010 to assess medication nonadherence among adults with hypertension. The overall prevalence of hypertension was 27.

Polyploidy road to therapy-induced cellular senescence and escape.

Therapy-induced cellular senescence (TCS), characterized by prolonged cell cycle arrest, is an in vivo response of human cancers to chemotherapy and radiation. Unfortunately, TCS is reversible for a subset of senescent cells, leading to cellular reproliferation and ultimately tumor progression. This invariable consequence of TCS recapitulates the clinical treatment experience of patients with advanced cancer.

Survivin and escaping in therapy-induced cellular senescence.

Therapy-induced accelerated cellular senescence (ACS) is a reversible tumor response to chemotherapy that is likely detrimental to the overall therapeutic efficacy of cancer treatment. To further understand the mechanism by which cancer cells can escape the sustained cell cycle arrest in ACS, we established a tissue culture model, in which the p53-null NCI-H1299 cells can be induced into senescence by an abbreviated exposure to a chemotherapeutic agent. Previously, we have reported that senescent cells overexpress Cdc2/Cdk1 when they bypassed the prolonged arrest and their viability is dependent on Cdc2/Cdk1 kinase activity.

Putative association of the single nucleotide polymorphisms in RASSF1A promoter with Korean lung cancer.

The RASSF1 gene, a putative tumor suppressor gene located on human chromosome 3p21, has attracted a great deal of attention because of frequent allelic loss and gene silencing via promoter hypermethylation in a variety of human malignancies. To evaluate the role of RASSF1A gene in lung cancer risk, genotypes of the RASSF1A promoter region (-710 C>T and -392T>C) were determined in 410 lung cancer patients and 410 normal subjects. Furthermore, to examine potential effects of the common haplotypes (C-C, T-T and C-T haplotypes) on RASSF1A transcription, luciferase reporter assays were performed in H2009 and H358 non-small cell lung cancer (NSCLC) cell lines.

Storytelling in person-centred care.

Storytelling is a powerful tool that can be used successfully to pass on knowledge, wisdom and expertise from educators to students. A story is more easily remembered and new concepts in nursing taught in story form are understood more readily. By the same token, the story of a resident's history allows caregivers to really understand who that person is and was, and in turn provide the care that will suit the unique needs of that resident.
