Evaluation of pedometry as a patient-centered outcome in patients undergoing hematopoietic cell transplant (HCT): A comparison of pedometry and patient-reports of symptoms, health, and quality of life.
Aims We evaluated pedometry as a novel patient-centered outcome because it enables passive continuous assessment of activity and may provide information about the consequences of symptomatic toxicity complementary to self-report. Methods Adult patients undergoing hematopoietic cell transplant (HCT) wore pedometers and completed PRO assessments during transplant hospitalization (4 weeks) and 4 weeks post-discharge. Patient reports of symptomatic treatment toxicities (single items from PROCTCAE, http://healthcaredelivery.cancer.gov/pro-ctcae) and symptoms, physical health, mental health, and quality of life (PROMIS Global-10, http://nih.promis.org), assessed weekly with 7-day recall on Likert scales, were compared individually with pedometry data, summarized as average daily steps per week, using linear mixed models. Results Thirty-two patients [mean age 55 (SD = 14), 63 % male, 84 % white, 56 % autologous, 43 % allogeneic] completed a mean 4.6 (SD = 1.5, range 1–8) evaluable assessments. Regression model coefficients (β) indicated within-person decrements in average daily steps were associated with increases in pain (β = -852; 852 fewer steps per unit increase in pain score, p<0.001), fatigue (β = -886, p<0.001), vomiting (β = -518, p<0.01), shaking/chills (β = -587, p<0.01), diarrhea (β = -719, p<0.001), shortness of breath (β = -1018, p<0.05), reduction in carrying out social activities (β = 705, p<0.01) or physical activities (β = 618, p<0.01), and global physical health (β = 101, p<0.001), but not global mental health or quality of life. Conclusions In this small sample of HCT recipients, more severe symptoms, impaired physical health, and restrictions in the performance of usual daily activities were associated with statistically significant decrements in objectively measured daily steps. Pedometry may be a valuable outcome measure and validation anchor in clinical research
K-Ras4A splice variant is widely expressed in cancer and uses a hybrid membrane-targeting motif
The KRAS oncogene is mutated more frequently in human cancer than any other. The KRAS transcript is alternatively spliced to give rise to two products, K-Ras4A and K-Ras4B, both of which are oncogenic when KRAS is mutated. We detected significant amounts of each transcript in human tumor cells and colorectal carcinomas. We found that K-Ras4A is targeted to the plasma membrane by dual targeting motifs distinct from those of K-Ras4B. Because interfering with membrane association of Ras proteins remains one of the most attractive approaches to anti-Ras therapy, efforts in this direction will have to disrupt both the K-Ras4A and the K-Ras4B membrane-targeting pathways

Thiopurine monotherapy is effective in ulcerative colitis but significantly less so in Crohn’s disease: long-term outcomes for 11 928 patients in the UK inflammatory bowel disease bioresource
Objective: Thiopurines are widely used as maintenance therapy in inflammatory bowel disease (IBD) but the evidence base for their use is sparse and their role increasingly questioned. Using the largest series reported to date, we assessed the long-term effectiveness of thiopurines in ulcerative colitis (UC) and Crohn’s disease (CD), including their impact on need for surgery. Design: Outcomes were assessed in 11 928 patients (4968 UC, 6960 CD) in the UK IBD BioResource initiated on thiopurine monotherapy with the intention of maintaining medically induced remission. Effectiveness was assessed retrospectively using patient-level data and a definition that required avoidance of escalation to biological therapy or surgery while on thiopurines. Analyses included overall effectiveness, time-to-event analysis for treatment escalation and comparison of surgery rates in patients tolerant or intolerant of thiopurines. Results: Using 68 132 patient-years of exposure, thiopurine monotherapy appeared effective for the duration of treatment in 2617/4968 (52.7%) patients with UC compared with 2378/6960 (34.2%) patients with CD (p<0.0001). This difference was corroborated in a multivariable analysis: after adjusting for variables including treatment era, thiopurine monotherapy was less effective in CD than UC (OR 0.47, 95% CI 0.43 to 0.51, p<0.0001). Thiopurine intolerance was associated with increased risk of surgery in UC (HR 2.44, p<0.0001); with a more modest impact on need for surgery in CD (HR=1.23, p=0.0015). Conclusion: Thiopurine monotherapy is an effective long-term treatment for UC but significantly less effective in CD

PICA
"PICA" means perverted appetite for substances not fit as food or of no nutritional value such as, bricks, clay, soil, ice, laundry starch, etc. The word ′′PICA′′ is derived from Latin word for Magpie, a species of bird that feeds on whatever it encounters. ′′PICA′′ has been observed in ethnic groups worldwide in primitive and modern cultures, in both sexes and in all age groups. The case presented here reports a 30 year old female patient who had craving for ingestion of gravel and brick fragments since the age of 13 years. Iron deficiency anemia was found after complete blood count and iron studies. The diagnosis of "PICA" requires that the patient is persistently eating non-food substances for at least 1 month and such behavior is appropriate for the child′s stage of development
McGibbon Syndrome: A report of three siblings
Amelogenesis Imperfecta (AI) is a collective term for a number of developmental conditions characterized by abnormal enamel formation. Only a few cases of AI have been reported to occur in association with syndromes and metabolic conditions. McGibbon Syndrome or AI and Nephrocalcinosis Syndrome are such disorders with defective enamel and renal calcifications. Early diagnosis of this condition is essential to prevent renal failure and death of the patient
