Abstract
PURPOSE Professionalism is a core physician competency and identifying students at risk for poor professional development early in their careers may allow for mentoring. This study identified indicators in the preclinical years associated with later professionalism concerns. METHODS A retrospective analysis of observable indicators in the preclinical and clinical years was conducted using two classes of students (n = 226). Relationships between five potential indicators of poor professionalism in the preclinical years and observations related to professional concerns in the clinical years were analyzed. RESULTS Fifty-three medical students were identified with at least one preclinical indicator and one professionalism concern during the clinical years. Two observable preclinical indicators were significantly correlated with unprofessional conduct during the clinical years: Three or more absences from attendance-required sessions (odds ratio 4.47; p=.006) and negative peer assessment (odds ratio 3.35; p=.049). CONCLUSIONS We identified two significant observable preclinical indicators associated with later professionalism concerns: excessive absences and negative peer assessments. Early recognition of students at risk for future professionalism struggles would provide an opportunity for proactive professional development prior to the clinical years, when students' permanent records may be affected. Peer assessment, coupled with attention to frequent absences, may be a method to provide early recognition.

Abstract
This study assesses the extent to which children under five years of age attending a growth-monitoring program are representative of the population as a whole. Bias in the prevalence of underweight estimated through growth-monitoring is assessed by comparing data from the program with prevalence estimates from the community-based Demographic and Health Surveys of 1988 and 1994. Geographic patterns of attendance at growth-monitoring are also examined through a comparison with census data, and trends in growth-monitoring data are also assessed. Provincial and national estimates of the prevalence of underweight from the two sources were not significantly different in 1988, but significant differences in prevalence estimates were identified in 1994. This suggests that growth-monitoring attendees were less representative of the general population in 1994 than at the start of the study period. The methodology used is transferable elsewhere, since the same data sets exist for many other African countries.

Abstract
BACKGROUND Cancer survivors may experience posttraumatic growth (PTG), positive psychological changes resulting from highly stressful events; however, the longitudinal course of PTG is poorly understood. PURPOSE The purpose of the present study was to determine trajectories of PTG in breast cancer survivors and associated characteristics. METHODS Women (N = 653) participating in a longitudinal observational study completed questionnaires within 8 months of breast cancer diagnosis and 6, 12, and 18 months later. Group-based modeling identified PTG trajectories. Chi-square tests and ANOVA detected group differences in demographic, medical, and psychosocial variables. RESULTS Six trajectory groups emerged. Three were stable at different levels of PTG, two increased modestly, and one increased substantially over time. Trajectory groups differed by age, race, receipt of chemotherapy, illness intrusiveness, depressive symptoms, active-adaptive coping, and social support. CONCLUSIONS This first examination of PTG trajectories in US cancer survivors elucidates heterogeneity in longitudinal patterns of PTG. Future research should determine whether other samples exhibit similar trajectories and whether various PTG trajectories predict mental and physical health outcomes.

Abstract
BACKGROUND Paternal depressive symptoms are associated with children's emotional and behavioural problems, which may be mediated by negative parenting. But there is no research on the influence of paternal depressive symptoms on children's emotion regulation and limited literature investigating fathers' parenting as a mediator in the pathway between paternal depressive symptoms and children's externalizing and internalizing problems. We aimed to investigate the mediating role of father-child conflict (at 3 years) in the association between postnatal paternal depressive symptoms (at 9 months) and children's emotional and behavioural problems (at 7 years) (aim 1). We also examined whether mediation pathways were more pronounced for boys or for girls (aim 2). METHOD Secondary data analysis was conducted on the Millennium Cohort Study, when children were 9 months, 3 years and 7 years old (n = 3520). Main study variables were measured by self-report questionnaires. Fathers completed the Rutter Scale (depressive symptoms) and the Parent-Child Relationship Questionnaire (father-child conflict), while mothers completed the Strengths and Difficulties Questionnaire and the Social Behaviour Questionnaire (child emotional and behavioural problems, emotion regulation). We used structural equation modelling to estimate direct, indirect and total effects of paternal depressive symptoms on child outcomes, mediated by father-child conflict whilst adjusting for relevant covariates (maternal depressive symptoms, child temperament, marital conflict, and socio-economic factors such as poverty indicator and fathers' education level). Multi-group and interaction analysis was then conducted to determine the differential effect by gender of the association between paternal depressive symptoms on child outcomes via father-child conflict. RESULTS Father-child conflict mediated the association between paternal depressive symptoms and emotion regulation problems [standardized indirect effect (SIE) 95% confidence interval (CI) -0.03 to -0.01, p < 0.001; standardized total effect (STE) 95% CI -0.05 to -0.01, p < 0.05] (aim 1). Father-child conflict mediated a larger proportion of the effect in boys (SIE 95% CI -0.03 to -0.01, p < 0.001; STE 95% CI -0.05 to 0.00, p = 0.063) than it did in girls (SIE 95% CI -0.02 to -0.01, p < 0.001; STE 95% CI -0.04 to 0.01, p = 0.216) (aim 2). CONCLUSIONS Father-child conflict may mediate the association between postnatal paternal depressive symptoms and children's emotion regulation problems. Paternal depressive symptoms and father-child conflict resolution may be potential targets in preventative interventions.

Abstract
The human embryonic stem cell line RCe013-A (RC-9) was derived under quality assured compliance with UK regulation, European Union Directives and International guidance for tissue procurement, processing and storage according to Good Manufacturing Practice (GMP) standards. The cell line was derived from a failed to fertilise oocyte voluntarily donated as unsuitable and surplus to fertility requirements following informed consent. RCe013-A (RC-9) shows normal pluripotency marker expression and differentiation to the three germ layers in vitro and in vivo. It has a normal 46XY male karyotype and microsatellite PCR identity, HLA and blood group typing data are available.

Abstract
Introduction. Diabetic retinopathy (DR) is a sight-threatening complication of diabetes. Telemedicine tools can prevent blindness. We aimed to investigate the patients' satisfaction when using such tools (fundus camera examination) and the effect of demographic and socioeconomic factors on participation in screening. Methods. Pilot study involving fundus camera screening and self-administered questionnaire on participants' experience during fundus examination (comfort, reliability, and future interest in participation), as well as demographic and socioeconomic factors was performed on 89 patients with known diabetes in Csongrád County, a southeastern region of Hungary. Results. Thirty percent of the patients had never participated in any ophthalmological screening, while 25.7% had DR of some grade based upon a standard fundus camera examination and UK-based DR grading protocol (Spectra™ software). Large majority of the patients were satisfied with the screening and found it reliable and acceptable to undertake examination under pupil dilation; 67.3% were willing to undergo nonmydriatic fundus camera examination again. There was a statistically significant relationship between economic activity, education and marital status, and future interest in participation. Discussion. Participants found digital retinal screening to be reliable and satisfactory. Telemedicine can be a strong tool, supporting eye care professionals and allowing for faster and more comfortable DR screening.

Abstract
Background: Hyperkalemia is a potentially life-threatening condition that is common in kidney disease patients. Insulin is used to treat hyperkalemia, but may cause hypoglycemia, especially in kidney disease when insulin may be metabolized more slowly. Objective: We compared the rates of hypoglycemia in patients with low estimated glomerular filtration rate (eGFR) using high versus low doses of insulin for hyperkalemia to determine if lower doses of insulin would decrease the incidence of hypoglycemia. Methods: This was a retrospective study of hospitalized patients receiving intravenous insulin for hyperkalemia during a 6-month period. Patients with low eGFR were analyzed based on how much insulin they received: high dose (10 units, n = 78) versus low dose (5 units, n = 71). Postdose nadir blood glucose values were examined for up to 8 hours after the dose. The percentage of hypoglycemia (blood glucose ≤70 mg/dl) and a subset of severe hypoglycemia (blood glucose <50 mg/dl) were then reported for each dose group. Results: A total of 149 doses were identified in patients with low eGFR. The rates of hypoglycemia were 16.7% and 19.7% ( P = 0.79), respectively, among high-dose (n = 78) and low-dose (n = 71) groups. Rates of severe hypoglycemia were 8.9% and 7.0%, respectively ( P = 0.90). More than 28% of hypoglycemic episodes with high doses occurred after 4 hours (median = 2.5 hours) compared with 14.3% with low doses (median = 2.38 hours). Conclusion: There was no difference in the rate of hypoglycemia or severe hypoglycemia between high or low doses of insulin in patients with low eGFR. We recommend monitoring up to 6 hours after insulin use in hyperkalemia.

Abstract
Objective To validate a mathematical algorithm that calculates risk of diabetic retinopathy progression in a diabetic population with UK staging (R0–3; M1) of diabetic retinopathy. To establish the utility of the algorithm to reduce screening frequency in this cohort, while maintaining safety standards. Research design and methods The cohort of 9690 diabetic individuals in England, followed for 2 years. The algorithms calculated individual risk for development of preproliferative retinopathy (R2), active proliferative retinopathy (R3A) and diabetic maculopathy (M1) based on clinical data. Screening intervals were determined such that the increase in risk of developing certain stages of retinopathy between screenings was the same for all patients and identical to mean risk in fixed annual screening. Receiver operating characteristic curves were drawn and area under the curve calculated to estimate the prediction capability. Results The algorithm predicts the occurrence of the given diabetic retinopathy stages with area under the curve =80% for patients with type II diabetes (CI 0.78 to 0.81). Of the cohort 64% is at less than 5% risk of progression to R2, R3A or M1 within 2 years. By applying a 2 year ceiling to the screening interval, patients with type II diabetes are screened on average every 20 months, which is a 40% reduction in frequency compared with annual screening. Conclusions The algorithm reliably identifies patients at high risk of developing advanced stages of diabetic retinopathy, including preproliferative R2, active proliferative R3A and maculopathy M1. Majority of patients have less than 5% risk of progression between stages within a year and a small high-risk group is identified. Screening visit frequency and presumably costs in a diabetic retinopathy screening system can be reduced by 40% by using a 2 year ceiling. Individualised risk assessment with 2 year ceiling on screening intervals may be a pragmatic next step in diabetic retinopathy screening in UK, in that safety is maximised and cost reduced by about 40%.

Abstract
INTRODUCTION Survival of patients after cytoreductive surgery (CRS) and heated intraperitoneal chemotherapy for appendiceal neoplasms is projected by conventional overall survival (OS) curves that do not address the survival time a patient has already accrued. We sought to study the conditional survival (CS) after CRS, contingent on patients surviving a fixed duration of time after surgery. METHODS A retrospective analysis of 493 appendiceal cancer patients from a prospective database was performed. OS was calculated for patients who achieved a complete CRS. CS was estimated based on Kaplan-Meier curves to determine what the patient's long-term survival (3-, 5-, 7-, or 10-year) would be if they were alive at 1, 2, or 3 years from surgery. RESULTS OS at 5 and 10 years for 137 low-grade patients with complete resections was 83.3 and 74.2 %, respectively. For low-grade patients still alive at 3 years, 5- and 10-year CS was 93.4 and 83.2 %, respectively. For the 35 high-grade patients with complete CRS who survived to 3 years, CS at 10 years was 41.7 %, while their 10-year conventional OS was 24.6 %. CONCLUSIONS Conventional analysis underestimates OS due to unpredictable variations in tumor biology. When adjusted for time already elapsed since surgery, improvements in survival estimates are more pronounced with high-grade tumors. CS outcomes can be used in determining the optimal frequency of long-term follow-up of these patients.

Abstract
Background Because parents with young children access primary health care services frequently, a key opportunity arises for Maternal and Child Health (MCH) nurses to actively work with families to support healthy infant feeding practices and lifestyle behaviours. However, little is known regarding the extent to which MCH nurses promote obesity prevention practices and how such practices could be better supported. Methods This mixed methods study involved a survey of 56 MCH nurses (response rate 84.8 %), 16 of whom participated in semi-structured qualitative interviews. Both components aimed to examine the extent to which nurses addressed healthy infant feeding practices, healthy eating, active play and limiting sedentary behavior during routine consultations with young children 0–5 years. Key factors influencing such practices and how they could be best supported were also investigated. All data were collected from September to December 2013. Survey data were analysed descriptively and triangulated with qualitative interview findings, the analysis of which was guided by grounded theory principles. Results Although nurses reported measuring height/length and weight in most consultations, almost one quarter (22.2 %) reported never/rarely using growth charts to identify infants or children at risk of overweight or obesity. This reflected a reluctance to raise the issue of weight with parents and a lack of confidence in how to address it. The majority of nurses reported providing advice on aspects of infant feeding relevant to obesity prevention at most consultations, with around a third (37 %) routinely provided advice on formula preparation. Less than half of nurses routinely promoted active play and only 30 % discussed limiting sedentary behaviour such as TV viewing. Concerns about parental receptiveness and maintaining rapport were key barriers to more effective implementation. Conclusion While MCH nurses are well placed to address obesity prevention in early life, there is currently a missed public health opportunity. Improving nurse skills in behaviour change counseling will be key to increasing their confidence in raising sensitive lifestyle issues with parents to better integrate obesity prevention practices into normal MCH service delivery.

Abstract
PURPOSE Since the Centers for Medicare & Medicaid Services implemented the End-Stage Renal Disease Prospective Payment System, dialysis providers have increasingly focused on balancing resource utilization and quality outcomes for the treatment of anemia in patients undergoing peritoneal dialysis. Limited data exist regarding anemia management outcomes for these patients in US-based dialysis centers after the implementation of the new payment system. METHODS This was a retrospective, observational, cohort study of stable PD patients with end-stage renal disease who received darbepoetin alfa for anemia management over a 15-month period (April 1, 2011-June 29, 2012). The medication was administered by staff in the home-training unit instead of being self-administered at home. The primary end point was mean quarterly hemoglobin (Hb) levels. Variability in Hb levels was assessed over the 5 quarters by using repeated measures ANOVA to test for differences in the observed mean SDs. FINDINGS In the 139 adult patients on stable peritoneal dialysis and meeting the eligibility criteria, mean (SD) Hb level by quarter was 10.8 (1.2) g/dL in quarters 2 and 3 of 2011, 10.5 (1.1) g/dL in quarter 4 of 2011, and 10.4 (1.1) g/dL in quarters 1 and 2 of 2012. Hb levels were stable (mean SDs, 0.58-0.72) over the 5 quarters of the study. Patient compliance with attendance for all scheduled home training unit visits was 84%. IMPLICATIONS PD patients who underwent darbepoetin alfa administration and twice-monthly laboratory testing in the home-training unit had stable Hb levels. Despite more frequent center visits compared with a home-administered approach, patient compliance was high.

Abstract
BACKGROUND Cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) used to treat peritoneal surface disease (PSD) from appendiceal cancer have shown variability in survival outcomes. The primary goal of this study was to determine predictors of surgical morbidity and overall survival. The secondary goal was to describe the impact of nodal status on survival after CRS/HIPEC for PSD from low-grade appendiceal (LGA) and high-grade appendiceal (HGA) primary lesions. METHODS A retrospective analysis of 1,069 procedures from a prospective database was performed. Patient characteristics, tumor grade, nodal status, performance status, resection status, morbidity, mortality, and survival were reviewed. RESULTS The study identified 481 CRS/HIPEC procedures: 317 (77.3 %) for LGA and 93 (22.7 %) for HGA lesions. The median follow-up period was 44.4 months, and the 30-day major morbidity and mortality rates were respectively 27.8 and 2.7 %. Major morbidity was jointly predicted by incomplete cytoreduction (p = 0.0037), involved nodes (p < 0.0001), and comorbidities (p = 0.003). Multivariate negative predictors of survival included positive nodal status (p = 0.003), incomplete cytoreduction (p < 0.0001), and preoperative chemotherapy (p = 0.04) in LGA patients and incomplete cytoreduction (p = 0.0003) and preoperative chemotherapy (p = 0.0064) in HGA patients. After complete cytoreduction, median survival was worse for patients with positive nodes than for those with negative nodes in LGA (85 months vs not reached [82 % alive at 90 months]; p = 0.002) and HGA (30 vs 153 months; p < 0.0001). CONCLUSIONS Positive nodes are associated with decreased survival not only for HGA patients but also for LGA patients even after complete cytoreduction. Nodal status further stratifies histologic grade as a prognostic indicator of survival. Patients with node-negative HGA primary lesions who receive a complete cytoreduction may experience survival comparable with that for LGA patients.

Abstract
Significance of signet ring cells in mucinous adenocarcinoma of the peritoneum from appendiceal origin has never been specifically studied. We retrospectively reviewed cases of mucinous adenocarcinoma of the peritoneum from appendiceal origin (n = 55) and collected clinical follow-up data. Signet ring cells were identified in 29 of 55 cases. No low-grade mucinous adenocarcinoma case (n = 11) had signet ring cells, whereas 29 of 44 high-grade mucinous adenocarcinoma cases did. Cases of high-grade mucinous adenocarcinoma were subdivided into 3 groups: (1) high-grade mucinous adenocarcinoma without signet ring cells (n = 15), (2) high-grade mucinous adenocarcinoma with signet ring cells only within mucin pools (n = 20), and (3) high-grade mucinous adenocarcinoma with signet ring cells invading tissue (n = 9). Overall survival (OS) and progression-free survival were subsequently evaluated. Five-year OS for cases of high-grade mucinous adenocarcinoma without signet ring cells and high-grade mucinous adenocarcinoma with signet ring cells within mucin pools were similar at 31.8% (SE, 14.4%) and 35.8% (SE, 13.9%), respectively. A significant survival difference was seen for cases of high-grade mucinous adenocarcinoma with signet ring cells invading tissue with a median OS of 0.5 years versus 2.9 and 2.4 years (P = .04 and P = .03), respectively, for cases of high-grade mucinous adenocarcinoma without signet ring cells and high-grade mucinous adenocarcinoma with signet ring cells within mucin pools. Finding signet ring cells floating in extracellular mucin pools made no prognostic difference when compared with cases of high-grade mucinous adenocarcinoma without signet ring cells. In contrast, high-grade mucinous adenocarcinoma with signet ring cells invading tissue was significant for worse survival, and thus, we propose reporting signet ring cell tissue invasion particularly when extensive.

Abstract
OBJECTIVE Posttraumatic growth (PTG) is defined as 'positive psychological change experienced as a result of a struggle with highly challenging life circumstances'. The current study examined change in PTG over 2 years following breast cancer diagnosis and variables associated with PTG over time. METHODS Women recently diagnosed with breast cancer completed surveys within 8 months of diagnosis and 6, 12, and 18 months later. Linear mixed effects models were used to assess the longitudinal effects of demographic, medical, and psychosocial variables on PTG as measured by the Posttraumatic Growth Inventory (PTGI). RESULTS A total of 653 women were accrued (mean age = 54.9, SD = 12.6). Total PTGI score increased over time mostly within the first few months following diagnosis. In the longitudinal model, greater PTGI scores were associated with education level, longer time since diagnosis, greater baseline level of illness intrusiveness, and increases in social support, spirituality, use of active-adaptive coping strategies, and mental health. Findings for the PTGI domains were similar to those for the total score except for the Spiritual Change domain. CONCLUSION PTG develops relatively soon after a breast cancer diagnosis and is associated with baseline illness intrusiveness and increases in social support, spirituality, use of active-adaptive coping strategies, and mental health.

Abstract
BACKGROUND Cytoreductive surgery (CRS)/Hyperthermic Intraperitoneal Chemotherapy (HIPEC) is associated with prolonged survival in selected patients with peritoneal surface disease. Yet, for elderly patients (older than 70 years of age) CRS/HIPEC is controversial, due to associated morbidity. METHODS A retrospective analysis of a prospective database of 950 procedures was performed. Type of malignancy, demographics, performance and resection status, hospitalization, morbidity, mortality, and survival were reviewed. RESULTS A total of 81 patients (median age 73, range 70-87) underwent CRS/HIPEC between 1991 and 2011. Median follow-up was 48.1 months. Complete cytoreduction was achieved in 44 %. Median survival was 31.8 months for appendiceal cancer, 41.5 for mesothelioma, 54.0 for ovarian cancer, 13.2 for colon cancer, and 7.6 for gastric cancer. The 30-day mortality was 13.6 %. The combined grade III and IV morbidity was 38 %. Median ICU and hospital stay for uncomplicated patients was 1 and 8 days, respectively. The 3-month mortality was 27.4 %. There were no deaths in the octogenarian group. In stepwise multivariate analysis, type of primary (p = 0.03), albumin (p = 0.02), and R status (p = 0.007) were predictive of survival only in the absence of complications. Splitting the data at the midpoint of surgical experience, there was a drop in 1- and 3-month mortality over time to 9.5 and 19.3 %, respectively, while the median survival increased from 11.2 (N = 39) to 46.9 months (N = 42). CONCLUSIONS HIPEC in the elderly is associated with a steep learning curve and considerable morbidity and mortality. However, age alone is not a contraindication for the procedure. Institutional experience and stringent patient selection are key factors for prolonged survival.

Abstract
Perioperative chemotherapy has been shown to improve disease-free survival compared with surgery alone for resectable colorectal liver metastases (CLM). We examined our experience with systemic chemotherapy in this clinical setting. A prospectively collected liver surgery database identified 210 patients treated for resectable CLM from 1996 to 2010. Results were correlated to four treatment groups: posthepatectomy adjuvant only, prehepatectomy preoperative only, perioperative (preoperative and adjuvant), and surgery only. Seventy-nine (37.6%) patients received posthepatectomy adjuvant only treatment, 33 (15.7%) received prehepatectomy preoperative only treatment, 46 (21.9%) received perioperative (preoperative and adjuvant) treatment, whereas 52 (24.8%) received surgery alone. Preoperative and adjuvant systemic chemotherapy regimens were as follows: 23 (29.1%) and 18 (14.4%) received a 5-fluorouracil monotherapy regimen, 19 (24.1%) and 31 (24.8%) received an irinotecan-based regimen, and 28 (35.4%) and 37 (29.6%) received an oxaliplatin-based regimen. Nine (11.4%) and 12 (9.6%) received some other unknown combination. Treatment groups showed no difference in gender, mean tumor size, number of tumors, margin status, or postoperative complications with the only difference being a higher incidence of metachronous tumors in the preoperative only and perioperative groups (P = 0.01). Median follow-up and overall survival were 25 and 41 months, respectively. The adjuvant, preoperative, perioperative, and surgery only groups had a median survival time of 48, 35, 39, and 29 months, respectively (log-rank P = 0.04). Independent predictors of overall survival on multivariate analysis included treatment algorithm used and postoperative complication status. Adjuvant only systemic therapy was associated with an improved survival in resectable CLM. Prospective randomized trials are needed to confirm these findings.

Abstract
BACKGROUND Pseudofolliculitis barbae (PFB) is an inflammatory condition of the face with a clinical presentation of papules in the beard area with occasional pustules or hypertrophic scarring, all of which develop in response to shaving. Prevalent in African American men, a limited amount of data have been published on the shave outcomes as they relate to clinically measurable responses and patient satisfaction scoring. The primary purpose of this study is to evaluate the impact of a daily shaving regimen and advanced shaving products on exacerbation of lesions and symptoms in patients with PFB. METHODS Ninety African American men were randomized to 1 of 3 treatment groups shaving 2 to 3 times per week with standard products (control group), shaving daily with standard products (daily standard group) or shaving daily with advanced products (daily advanced). The number of pustules, papules, ingrown hairs, and investigator's assessment of severity and subjective symptoms of itching and burning/stinging were assessed at baseline, week 6, and week 12. The response to treatment was also assessed by the investigator and the subject at weeks 6 and 12. Secondary measures including questionnaires regarding baseline shave practices were also correlated with outcomes variables. RESULTS There were no significant differences noted between the 3 groups for papule (P=.32) or pustule (P=.46) count for the 12-week study. However, there was a significant mean papule reduction from baseline detected for both the control and daily advanced groups. In addition, compared to baseline, there was a significant reduction in ingrown hairs for the control group, and a directional reduction in ingrown hairs for the daily advanced group. There were significant group differences between the control group and both daily shaving groups, with the control group seeing significantly fewer ingrown hairs (P=.005 for control vs daily standard group and P=.04 for control vs daily advanced group). There were no significant group differences among the 3 groups for investigator-graded severity (P=.43) and response to treatment (P=.51). There was a significant perceived improvement in the response to treatment (P=.007) and itching (P=.002) for the daily advanced group vs the control group.

Abstract
BACKGROUND Cytoreductive surgery and hyperthermic intraperitoneal chemotherapy is a promising modality for peritoneal carcinomatosis. Splenectomy is frequently required, however effect upon hematotoxicity is unknown. METHODS 195 patients undergoing the procedure were evaluated and granulocyte colony stimulating factor administered for white blood cell counts <4.0. RESULTS 52% of 195 underwent splenectomy; average white blood cell and platelet nadirs were 6.1,172. Non-splenectomy patients averaged white blood cell nadir 4.6, platelet nadir 164.1. Granulocyte colony stimulating factor administered in 29% of splenectomy, 43% of non-splenectomy (P=0.043). CONCLUSION Splenectomy ameliorates hematotoxicity of hyperthermic intraperitoneal chemotherapy and significantly reduces post-operative granulocyte colony stimulating factor requirements.

Abstract
The role of the major histocompatibility complex (MHC) in the immune response makes it an attractive candidate gene for associations with disease resistance and susceptibility. This study describes genetic variability in the BoLA-DRB3 in Iranian buffaloes. Heminested PCR-RFLP method was used to identify the frequency of BoLA-DRB3 alleles. The BoLA-DRB3 locus is highly polymorphic in the study herd (12 alleles). Almost 63.50% of the alleles were accounted for by four alleles (BoLA-DRB3.2 ∗48, ∗20, ∗21, and obe) in Iranian buffalo. The DRB3.2 ∗48 allele frequency (24.20%) was higher than the others. The frequencies of the DRB3.2 ∗20 and DRB3.2 ∗21 are 14.52 and 14.00, respectively, and obe and gbb have a new pattern. Significant distinctions have been found between Iranian buffalo and other cattle breed studied. In the Iranian buffaloes studied alleles associated with resistance to various diseases are found.

Abstract
A new finite difference (FD) method for calculating the time evolution of complex transverse magnetization in diffusion-weighted magnetic resonance imaging and spectroscopy experiments is described that incorporates periodic boundary conditions. The new FD method relaxes restrictions on the allowable time step size employed in modeling which can significantly reduce computation time for simulations of large physical extent and allow for more complex, physiologically relevant, geometries to be simulated.
