Abstract
BACKGROUND The selection of the most appropriate treatment combinations requires the balancing of benefits and harms of these treatment options as well as the patients' preferences for the resulting outcomes. OBJECTIVE This research aimed at estimating and comparing the utility weights between elderly women with early stage hormone receptor positive (HR+) breast cancer receiving a combination of radiotherapy and hormonal therapy after breast conserving surgery (BCS) and those receiving a combination of BCS and hormonal therapy. METHODS The Surveillance, Epidemiology, and End Results (SEER) linked with Medicare Health Outcomes Survey (MHOS) was used as the data source. Health utility weights were derived from the VR-12 health-related quality of life instrument using a mapping algorithm. Descriptive statistics of the sample were provided. Two sample t-tests were performed to determine potential differences in mean health utility weights between the two groups after propensity score matching. RESULTS The average age at diagnosis was 72 vs. 76 years for the treated and the untreated groups, respectively. The results showed an inverse relationship between the receipt of radiotherapy and age. Patients who received radiotherapy had, on average, a higher health utility weight (0.70; SD = 0.123) compared with those who did not receive radiotherapy (0.676; SD = 0.130). Only treated patients who had more than two comorbid conditions had significantly higher health utility weights compared with patients who were not treated. CONCLUSIONS The mean health utility weights estimated for the radiotherapy and no radiotherapy groups can be used to inform a comparative cost-effectiveness analysis of the treatment options. However, the results of this study may not be generalizable to those who are outside a managed care plan because MHOS data is collected on managed care beneficiaries.

Abstract
Low birth weight (LBW) is a health concern in developing countries. Leptin and insulin-like growth factor-I (IGF-I) are factors that influence LBW. A case-control study was conducted at Medani hospital, Sudan. Cases were women who had LBW deliveries ( 2,500 g) and controls were women with normal-weight babies ( 2.500 – 4,000 g). Sociodemographic and obstetrical characteristics were gathered from both groups and leptin and IGF-I levels were measured by ELISA. Cases and controls (45 in each arm) were matched in their basic data. The median (interquartile) of maternal leptin levels [9.9 (1.9 – 21.8) vs. 16.0 (9.6 – 20.8), ng/ml; P0.001] and IGF-I [1.6 (0.7 – 20.0) vs. 6.1 (4.3 – 7.1) ng/ml ; P 0.001] were significantly lower in cases than in controls. Likewise, cord serum leptin [5.8 (2.1 – 12.6) vs. 20.0 (5.1 – 37.8) ng/ml; P0.001] and cord serum IGF-I [1.7 (1.3 – 2.0) vs. 6.9 (5.9 – 7.4) ng/ml; P0.001] levels were significantly lower in cases than in controls. Significant positive correlation was found between birth weight and cord leptin ( r0.398), maternal ( r0.795) and cord ( r0.863) IGF-I levels. Maternal and cord leptin and IGF-I levels were significantly lower in LBW babies.

Abstract
To examine the association of major types of comorbidity with late-stage prostate cancer, a random sample of 11,083 men diagnosed with prostate cancer during 2002-2007 was taken from the Florida Cancer Data System. Individual-level covariates included demographics, primary insurance payer, and comorbidity following the Elixhauser Index. Socioeconomic variables were extracted from Census 2000 data and merged to the individual level data. Provider-to-case ratio at county level was alsocomputed. Multilevel logistic regression was used to assess associations between these factors and late-stage diagnosis of prostate cancer. Higher odds of late-stage diagnosis was significantly related to presence of comorbidities, being unmarried, current smoker, uninsured, and diagnosed in not-for-profit hospitals. The study reported that the presence of certain comorbidities, specifically 10 out of the 45, was associated with late-stage prostate cancer diagnosis. Eight out of 10 significant comorbid conditions were associated with greater risk of being diagnosed at late-stage prostate cancer. On the other hand, men who had chronic pulmonary disease, and solid tumor without metastasis, were less likely to be diagnosed with late-stage prostate cancer. Late-stage diagnosis was associated with comorbidity, which is often associated with increased health care utilization. The association of comorbidity with late-stage prostate cancer diagnosis suggests that individuals with significant comorbidity should be offered routine screening for prostate cancer rather than focusing only on managing symptomatic health problems.

Abstract
Respiratory tract infection is a major cause of hospitalization in children. Although most such infections are viral in origin, it is difficult to differentiate bacterial and viral infections, as the clinical symptoms are similar. Multiplex polymerase chain reaction (PCR) methods allow testing for multiple pathogens simultaneously and are, therefore, gaining interest. This prospective case-control study was conducted from October 2013 to February 2014. Nasopharyngeal (NP) and oropharyngeal (throat) swabs were obtained from children admitted with severe acute respiratory infection (SARI) at a tertiary hospital. A control group of 40 asymptomatic children was included. Testing for 16 viruses was done by real-time multiplex PCR. Multiplex PCR detected a viral pathogen in 159/177 (89.9 %) patients admitted with SARI. There was a high rate of co-infection (46.9 %). Dual detections were observed in 64 (36.2 %), triple detections in 17 (9.6 %), and quadruple detections in 2 (1.1 %) of 177 samples. Seventy-eight patients required intensive care unit (ICU) admission, of whom 28 (35.8 %) had co-infection with multiple viruses. AdV, HBoV, HRV, HEV, and HCoV-OC43 were also detected among asymptomatic children. This study confirms the high rate of detection of viral nucleic acids by multiplex PCR among hospitalized children admitted with SARI, as well as the high rate of co-detection of multiple viruses. AdV, HBoV, HRV, HEV, and HCoV-OC43 were also detected in asymptomatic children, resulting in challenges in clinical interpretation. Studies are required to provide quantitative conclusions that will facilitate clinical interpretation and application of the results in the clinical setting.

Abstract
BACKGROUND Use of perioperative chemotherapy had significantly improved prognosis of localized gastric cancer. Two studies have validated this approach using cisplatin based chemotherapy despite important toxicities. We conducted this study with the aim to evaluate efficacy and toxicity of FOLFOX regimen in this setting. MATERIAL AND METHODS This is a retrospective study including patients followed for gastric cancer in the Oncology Department of the military hospital Mohamed V in Rabat, Morocco over a period of 7 years from 2007 to 2013. Patients received 4 cycles of mFOLFOX as perioperative regimen. Assessment of tumor response after completion of preoperative chemotherapy was granted by comparative CT scan, tumor markers measurements and R0 surgery rate.Adverse events were graded according to classification of the National Cancer Institute Common Toxicity Criteria version 4.0. RESULTS Thirty-one patients were included in this study. Use of preoperative chemotherapy showed partial response in fourteen patients (45.1%), stabilization in fifteen patients (48.4%). Tumor markers CEA and CA 19- 9 were significantly decreased. R0 resection rate was 83.87%. Only 2 (6.45%) cases of grade 3/4 hematologic toxicity were reported in our study. Achieving programmed postoperative chemotherapy was possible in 72.41% of patients. CONCLUSIONS Our study is limited by the retrospective design and small sample size but FOLFOX chemotherapy seems effective and well tolerated in this setting and its place deserves to be studied in a larger study.

Abstract
The aim of this study was to investigate the seasonal variation and hypertensive disorders of pregnancy in eastern Sudan, in the period between January 2008 and December 2010. The medical files of women attending at Kassala hospital, eastern Sudan with hypertension, with or without proteinuria were retrospectively retrieved. The data of patients with hypertensive disorders of pregnancy were compared with a similar number of controls that were normotensive and non-proteinuric. During the study period, there were 9,578 deliveries; 153 patients had hypertensive disorders of pregnancy, yielding an incidence rate of 1.6%. Of all cases and controls (306), there were 183 (59.8%) deliveries in winter, 84 (27.5%) in summer and 39 (12.7%) in autumn. The highest rate of pre-eclampsia was in winter (1.1%) (CI = 1.1-2.7, OR = 1.7, p = 0.004) and the lowest rate was in autumn (0.2%) (CI = 0.4-1.8, OR = 0.8, p = 0.758.). Our study revealed significant association between the incidence of hypertensive disorders of pregnancy and the winter season (103 (67.3%) vs 80 (52.3%), p = 0.001). Thus, more attention in the winter season might reduce the morbidity and mortality of hypertensive disorders of pregnancy.

Abstract
OBJECTIVES To examine the impact of health insurance type on treatment of early-stage breast cancer using breast-conserving surgery (BCS) with radiation therapy (RT) among women in Florida and identify factors that contribute to the variations in receiving the treatment in women with the same health insurance type. STUDY DESIGN AND METHODS Breast cancer cases diagnosed during 1997 to 2002 were obtained from the Florida Cancer Data System. Women 40 years and older diagnosed with localized breast cancer were included. Demographic, insurance, and treatment information were extracted and linked with 2000 census data. χ² and multilevel logistic regression analyses were used. RESULTS A total of 33,706 women were diagnosed with localized breast cancer in Florida during 1997 to 2002. The average age of the women was 66 years, 58.62% had BCS while 38.61% had mastectomy, and only 2.77% had no surgical treatment. Type of health insurance plays a significant role in receiving BCS with RT. Furthermore, we found significant variations in the use of BCS with RT among women who have the same type health insurance by marital status, age, tumor size, year of diagnosis, level of education, and poverty level. CONCLUSIONS Although clinical practice guidelines recommend BCS with RT to treat women with localized breast cancer, significant differences in receiving the recommended treatment is found between and within types of health insurance. Identifying cultural barriers and educating the public about available treatment options are the major policy implications of this study. These observed differences require further study.

Abstract
OBJECTIVE To evaluate the bond strength durability of a single-step self-etch adhesive to dentin pretreated with either ethanol-based chlorhexidine (ECHX) or water-based chlorhexidine (WCHX) after storage in artificial saliva and under intrapulpal pressure simulation (IPPS). METHODS The occlusal enamel of 30 freshly extracted premolars was trimmed to expose midcoronal dentin. Roots were sectioned to expose the pulp chamber. Specimens were distributed over three groups (n=10) according to the dentin pretreatment used. In the first group, Adper Easy One (3M ESPE) was applied to the dentin surfaces according to the manufacturer's instructions (control group). In the second group, dentin was pretreated before bonding with 1 mL of 2% CHX diacetate dissolved in 100% ethanol (ECHX). The third group received the same pretreatment; however, CHX was dissolved in distilled water (WCHX). Pretreatment and bonding were carried out while the specimens were subjected to IPPS. Resin composite (Valux Plus, 3MESPE) buildups were made. After curing, specimens were stored in artificial saliva and under IPPS at 37°C in a specially constructed incubator (n=5/group) either for 24 hours or six months prior to testing. Thereafter, bonded specimens were sectioned into sticks with a cross section of 0.9 ± 0.01 mm(2) and subjected to microtensile bond strength (μTBS) testing (n=25/subgroup) using a universal testing machine. Data were statistically analyzed using two-way analysis of variance (ANOVA) with repeated measures, one-way ANOVA , and Bonferroni post hoc tests (p≤0.05). Failure modes were determined using a scanning electron microscope. RESULTS After 24 hours of storage, control and WCHX groups revealed significantly higher μTBS than the ECHX group. After six-month storage in artificial saliva and IPPS, only the WCHX group maintained its μTBS value. The predominant mode of failure was the mixed type, except for the ECHX group, which was mostly adhesive. CONCLUSION Pretreatment of the dentin with ECHX had a negative effect on bonding of the tested single-step self-etch adhesive; however, WCHX showed bond stability under IPPS.

Abstract
In prospective study, the various reasons for conversion in laparoscopic cholecystectomy were shown and recommended various measures to decrease the incidence of conversion and associated complications with this procedure. Fifty cases of conversion in laparoscopic cholecystectomy were studied in Dhaka Medical College Hospital & Bangabandhu Sheikh Mujib Medical University from July 2002 to July 2004. The commonest cause of conversion was dense pericholecystic adhesion or unclear anatomy (24%). Next common cause was accidental injury to surrounding structures (18%) and uncontrolled bleeding (14%) and thick fibrosed gall bladder (14%). Other causes were gall bladder wall perforation (6%), carcinoma gall bladder (6%) and choledocholithiasis (6%), anatomic variation (4%), equipment failure (4%), cholecystoduodenal fistula (2%) and choledochal cyst (2%). Proper case selection, good laparoscopic skill and adequate experience of the surgeon are the prerequisites for safe laparoscopic cholecystectomy and thereby reducing conversion rate.

Abstract
INTRODUCTION Identifying clinically relevant comorbid conditions might lead to effective control of prostate cancer- specific risk factors and provide opportunities to improve patient care and outcomes. There are challenges in assessing comorbidity using linked databases such as statewide hospital administrative data and state cancer registry. The objective was to compile a comprehensive list of clinically relevant comorbid conditions for patients with prostate cancer using registry and statewide diagnosis databases. METHODS Florida Cancer Data System cases were linked with the inpatient/ outpatient diagnosis information. The Elixhauser Comorbidity Index was used as a reference. Conditions not captured by Elixhauser were identified, and grouped into clinically meaningful categories. Descriptive analysis was performed on comorbidity conditions and major study population variables. Associations of comorbidity with selected demographic and disease characteristics were examined. RESULTS Twenty-nine Elixhauser and 16 additional categories were examined within the 1 record per patient data set. Statistically significant association was found between comorbidity with race, stage, and age. Blacks had a higher mean number of conditions compared to whites. A higher proportion of blacks had at least 1 comorbid condition compared to whites. Additional conditions identified by this research capture more comorbidities for white men. Distinct trends towards larger number of comorbidities with older age at diagnosis and advanced disease stage were observed. CONCLUSIONS The Elixhauser Comorbidity Index captured the majority of comorbidities in the study population while the additional conditions identified by this research add more information. This study offers important insights into the challenges and process to identify relevant comorbidities for prostate cancer patients.

Abstract
A method was developed to categorize prostate cancer treatments for epidemiologic and outcomes studies. A total of 60,497 prostate cancer cases from the Florida Cancer Data System diagnosed between 2001 and 2007 were used. The classification has the following properties. First, the treatments classified in the same group are clinically comparable and capture all prostate cancer treatments or combinations of treatments (exhaustive classification). Second, the grouping was set up in a way that each patient is captured in only 1 treatment category without leaving out any patient due to treatment type (mutually exclusive categories). The prostate cancer cases were initially categorized into 14 combinations of treatment, which were then collapsed into 8 broader groups in order to maintain a large sample size for all groups, with treatments remaining clinically comparable within a group.

Abstract
The association between thyroid autoimmunity and thyroid cancer was carried out in a series of solitary thyroid nodules submitted to fine-needle aspiration cytology and subsequent histopathology. US guided FNACs were obtained from 295 unselected consecutive patients with single thyroid nodules and positive (98) or negative (197) serum anti-thyroid antibody. Cytological results were classified in three classes of increased risk of malignancy: low risk (class II); indeterminate risk (class III); and suspect or malignant (class IV). A higher prevalence of class III (29.6%, p<0.05) and class IV (17.34%, p<0.05) and lower prevalence of class II (52.06%, p<0.01) were found in ATA+ nodules respectively. By multivariate logistic regression analysis ATA+ conferred a significant risk (odds ratio: 1.97 & 95% confidence interval: 0.97-3.97) for class IV cytology independently for age and sex. In 53 patients where thyroidectomy was carried out, thyroid cancer was found in (86.66%) patients with class IV nodules, in (19.4%) of class III nodules (all ATA-) and in none of 7 class II nodules. Histologically proven thyroid cancer (mostly papillary) was then observed in a higher proportion (13.2%) of ATA+, when compared with ATA- nodules (8.1%, p>0.01), but the significance of this finding is limited by the low number of class II nodules operated on. The presence of ATA+ confers an increased risk of suspicious or malignant cytology in solitary thyroid nodules.

Abstract
Medical files of women delivered at Kassala Hospital, Eastern Sudan in the period of January-December 2009 were reviewed retrospectively. Out of 4,689 delivered women, 14.7% were teenagers, 67.1% had no antenatal care and 12.6% were grandmultiparous. Obstetric complications included: pre-term birth (2.6%); pre-eclampsia/eclampsia (4.2%); haemorrhage (2.9%); malpresentation (5.5%); obstructed labour (1.9%) and ruptured uterus (0.6%). Caesarean delivery rate was 31.1%. While 89.4% of the newborn babies were taken home, 6% were admitted to the nursery, 4.4% were stillbirths, and 0.2% immediate neonatal deaths. There were 26 maternal deaths (550 per 100,000 live births), mainly due to septicaemia (38.4%), haemorrhage (19.2%), embolism (15.3%) and malaria (11.5%). Thus, there is a high frequency of maternal morbidities and mortality which needs improvement in obstetric care. It is important to make visits from a tertiary hospital to the region to collect statistics and discuss management of the problems they reveal, with the local staff.

Abstract
A 55 years old male was admitted in the surgical unit of Dhaka Medical College & Hospital with the complaints of pain and discomfort in the upper abdomen for 1 day and hiccough and vomiting for several episodes for same duration. He had history of abdominal operation 10 years back for his peptic ulcer disease probably due to pyloric stenosis. On examination a linear scar mark was present along the upper midline region & visible peristalsis was seen on the left hypochondriac region. A palpable diffuse lump was present in the left hypochondriac region which was intraperitoneal seemed to be distended gut and the peristaltic wave moved from left to right. Endoscopy of upper GIT Showed loops of small intestine (evidenced by valvulae conneventes) protruded through a stoma suggestive of jejunogastric intussusception. Laparotomy revealed a portion of adherent small gut already become gangrenous so the whole portion of the intussuscepted gut was resected. After that revision and take-down of the anastomosis was done with vicryl stitches. The post operative period was uneventful. The patient underwent regular follow up.

Abstract
Cardiac transplantation is in decline, in contrast to other solid organs where the number of solid organ transplants from donors after circulatory death (DCD) is increasing. Hearts from DCD donors are not currently utilized due to concerns that they may suffer irreversible cardiac injury with resultant poor graft function. Using a large animal model, we tested the hypothesis that hearts from DCD donors would be suitable for transplantation. Donor pigs were subjected to hypoxic cardiac arrest (DCD) followed by 15 min of warm ischemia and resuscitation on cardiopulmonary bypass, or brainstem death (BSD) via intracerebral balloon inflation. Cardiac function was assessed through load-independent measures and magnetic resonance imaging and spectroscopy. After resuscitation, DCD hearts had near normal contractility, although stroke volume was reduced, comparable to BSD hearts. DCD hearts had a significant decline in phosphocreatine and increase in inorganic phosphate during the hypoxic period, with a return to baseline levels after reperfusion. After transplantation, cardiac function was comparable between BSD and DCD groups. Therefore, in a large animal model, the DCD heart maintains viability and recovers function similar to that of the BSD heart and may be suitable for clinical transplantation. Further study is warranted on optimal reperfusion strategies.

Abstract
Bovine tuberculosis (BTB) is a considerable health threat to livestock keepers and general communities in many developing countries. Information on genetic resistance or susceptibility because of polymorphisms of candidate genes could be used in making selection decisions for breeding disease tolerant/resistant animals. Here, we investigated associations between polymorphisms at the solute carrier family 11 (proton-coupled divalent metal ion transporters), member 1 gene (SLC11A1, previously known as natural resistant associated macrophage protein 1, NRAMP1), with BTB phenotypes in Chadian cattle. Phenotypes were (i) single intradermal comparative cervical tuberculin test (SICCT) outcome, (ii) presence of gross visible lung lesions, (iii) a bacteriological culture test outcome and (iv) a predicted true BTB infection status using a Bayesian model. All traits were recorded as binary (presence or absence) traits. A total of 211 cattle were genotyped for a microsatellite within the SLC11A1 candidate gene. Standard linear and threshold-liability models regressing BTB traits on copy number of SLC11A1 alleles revealed statistically significant effects of SLC11A1 alleles (P < 0.001) on most BTB traits. Polymorphisms (alleles 211, 215 and 217) are significantly related to lower incidence of BTB traits in Chadian cattle. This is the first study to report the association of SLC11A1 gene polymorphisms with BTB traits in Chadian or any other African cattle breeds.

Abstract
New nano-blue ceramic pigments of Co(x)Mg(1-x)Al(2)O(4) (0< or =x< or =0.1) have been prepared by co-precipitate-combustion as a hybrid method using urea as a fuel at 500 degrees C in open furnace in air atmosphere. The structure of pigment is assigned based on TGA/DTA/DrTGA analyses, X-ray diffraction (XRD) and transmission electron microscopy (TEM). Also, electronic spectra, infrared (IR) and diffuse reflectance spectroscopy (DRS) using CIE L*a*b* parameter measurement techniques were used. The results revealed that the nano-particle size of pigments were obtained in the range 30-38 nm as well as the varying colors and particle size as a result of different calcinations temperatures within the range of 500-1200 degrees C for 2h.

Abstract
A cross-sectional hospital-based study was carried out at Tikrit teaching hospital, Iraq, from October 2004 to September 2005, to identify the prevalence and etiology of nosocomial infectious diarrhoea among children under 5 years of age. Of 259 children admitted to the paediatric ward for reasons other than diarrhoea and hospitalized for more than 3 days, clinical and laboratory analysis of stool samples showed nosocomial diarrhoea in 84 children (32.4%). The most common causative agents were enteropathogenic Escherichia coli (25.9%), Clostridium difficile (21.0%) and rotavirus (18.5%). Single infectious agents caused 63.1% of the cases, while mixed infections were detected in 16.7%; in 20.2% of children the cause remained unknown.
