Response to: The Ongoing Debate about the Impact of the 150-Hour Education Requirement on the Supply of Certified Public Accountants
Authors: Allen Arthur C. , Woodland Angela M. 
Published: June 2012

ABSTRACT
In an earlier paper in this journal, Allen and Woodland (2006; hereafter AW) provided evidence that the 150-hour education requirement for licensure significantly reduced the number of candidates taking and passing the CPA exam, but had little effect on pass rates. Gramling and Rosman (2009; hereafter GR) extended AW by examining the number of candidates based on whether the 150-hour requirement applies to the exam or for licensure, concluding that the 150-hour requirement does not reduce the number of candidates taking and passing the exam. In this paper, we reopen the discussion of whether the 150-hour education requirement affects entrants into the accounting profession by comparing the AW and GR research designs and conclusions. We conclude that the GR research design yields results about whether differences in 150-hour implementation methods affect the number of candidates taking and passing the exam, but does not directly provide evidence about whether the 150-hour education requirement itself affects the number of candidates.

Published: June 2012

AbstractObjectives:To assess the reporting quality of Cochrane and non-Cochrane systematic reviews (SR) in orthodontics and to compare the reporting quality (PRISMA score) with methodological quality (AMSTAR criteria).Materials and Methods:Systematic reviews (n  =  109) published between January 2000 and July 2011 in five leading orthodontic journals were identified and included. The quality of reporting of the included reviews was assessed by two authors in accordance with the PRISMA guidelines. Each article was assigned a cumulative grade based on fulfillment of the applicable criteria, and an overall percentage score was assigned. Descriptive statistics and simple and multiple linear regression analyses were undertaken.Results:The mean overall PRISMA score was 64.1% (95% confidence interval [CI], 62%–65%). The quality of reporting was considerably better in reviews published in the Cochrane Database of Systematic Reviews (P &lt; .001) than in non-Cochrane reviews. Both multivariable and univariable analysis indicated that journal of publication and number of authors was significantly associated with the PRISMA score. The association between AMSTAR score and modified PRISMA score was also found to be highly statistically significant.Conclusion:Compliance of orthodontic SRs published in orthodontic journals with PRISMA guidelines was deficient in several areas. The quality of reporting assessed using PRISMA guidelines was significantly better in orthodontic SRs published in the Cochrane Database of Systematic Reviews.

Abstract
Objective—To estimate the prevalence of canine parvovirus (CPV) strains among dogs with enteritis admitted to a referral hospital in the southwestern United States during an 11-month period and to compare diagnostic test results, disease severity, and patient outcome among CPV strains.
Design—Prospective observational study.
Animals—72 dogs with histories and clinical signs of parvoviral enteritis.
Procedures—For each dog, a fecal sample or rectal swab specimen was evaluated for CPV antigen via an ELISA. Subsequently, fecal samples (n = 42 dogs) and pharyngeal swab specimens (16) were obtained and tested for CPV antigen via an ELISA and CPV DNA via a PCR assay. For specimens with CPV-positive results via PCR assay, genetic sequencing was performed to identify the CPV strain.
Results—56 dogs tested positive for CPV via ELISA or PCR assay. For 42 fecal samples tested via both ELISA and PCR assay, 27 had positive results via both assays, whereas 6 had positive PCR assay results only. Ten pharyngeal swab specimens yielded positive PCR assay results. Genetic sequencing was performed on 34 fecal or pharyngeal swab specimens that had CPV-positive PCR assay results; 25 (73.5%) were identified as containing CPV type-2c, and 9 (26.5%) were identified as containing CPV type-2b. No association was found between CPV strain and disease severity or clinical outcome.
Conclusions and Clinical Relevance—CPV type-2b and CPV type-2c posed similar health risks for dogs; therefore, genetic sequencing of CPV does not appear necessary for clinical management of infected patients. The diagnostic tests used could detect CPV type-2c.

Abstract
Objective—To compare time to loss of consciousness (LOC) and effective maintenance of anesthesia following intraosseous (IO) and IV administration of propofol in rabbits.
Design—Evaluation study.
Animals—24 New Zealand White rabbits.
Procedures—Rabbits were selected to receive IO (n = 6) or IV (6) bolus administration of 1% propofol (12.5 mg/kg [5.67 mg/lb]) only or an identical bolus of propofol IO (6) or IV (6) followed by a constant rate infusion (CRI; 1 mg/kg/min [0.45 mg/lb/min]) by the same route for 30 minutes. Physiologic variables were monitored at predetermined time points; time to LOC and durations of anesthesia and recovery were recorded.
Results—Following IO and IV bolus administration, mean time to LOC was 11.50 and 7.83 seconds, respectively; changes in heart rate, respiratory rate, oxygen saturation (as measured by pulse oximetry), and mean arterial blood pressure values were evident, but findings did not differ between groups. For the IO- and IV-CRI groups, propofol-associated changes in heart rate, oxygen saturation, and mean arterial blood pressure values were similar, and although mean arterial blood pressure decreased significantly from baseline, values remained > 60 mm Hg; respiratory rate decreased significantly during CRI in both groups, but remained higher in the IO-CRI group. Anesthesia and recovery time did not differ between the IO- and IV-CRI groups.
Conclusions and Clinical Relevance—In all evaluated aspects of anesthesia, IO administration of propofol was as effective as IV administration in rabbits. Results suggested that total IO anesthesia can be performed in rabbits with limited vascular access.

Published: June 2012

Abstract
Objective—To describe the relationship between veterinarian and client genders and veterinarian-client-patient communication.
Design—Cross-sectional descriptive study.
Sample—Random sample of 50 companion animal practitioners in southern Ontario and a convenience sample of 300 clients and their pets.
Procedures—For each practitioner, 6 clinical appointments were videotaped, and the resulting 300 videotapes were analyzed with the Roter interaction analysis system (RIAS). Linear regression was conducted to study the relationship between demographic factors, measures of veterinarian-client-patient communication, and gender of the veterinarian and client.
Results—Female veterinarians conducted more relationship-centered appointments, provided more positive and rapport-building statements, talked more to the patient, and were perceived as less hurried or rushed, compared with male veterinarians. Clients were more likely to provide lifestyle-social information to female veterinarians. Same-gender veterinarian-client interactions were relationship centered and included client provision of more lifestyle-social information.
Conclusions and Clinical Relevance—Gender influenced veterinarian-client-patient communication, and previously described physician gender differences in medical communication were largely replicated in the veterinary context.
Generalised elliptic functions
Authors: England Matthew , Athorne Chris 
Published: June 2012

Abstract
We consider multiply periodic functions, sometimes called Abelian functions, defined with respect to the period matrices associated with classes of algebraic curves. We realise them as generalisations of the Weierstraß ℘-function using two different approaches. These functions arise naturally as solutions to some of the important equations of mathematical physics and their differential equations, addition formulae, and applications have all been recent topics of study.
The first approach discussed sees the functions defined as logarithmic derivatives of the σ-function, a modified Riemann θ-function. We can make use of known properties of the σ-function to derive power series expansions and in turn the properties mentioned above. This approach has been extended to a wide range of non hyperelliptic and higher genus curves and an overview of recent results is given.
The second approach defines the functions algebraically, after first modifying the curve into its equivariant form. This approach allows the use of representation theory to derive a range of results at lower computational cost. We discuss the development of this theory for hyperelliptic curves and how it may be extended in the future. We consider how the two approaches may be combined, giving the explicit mappings for the genus 3 hyperelliptic theory. We consider the problem of generating bases of the functions and how these decompose when viewed in the equivariant form.

Published: June 2012

Abstract
The refractive index (RI) of light propagating in a medium of quark-gluon plasma (QGP) is studied. The weakly coupled QGP is studied in the framework of hard-thermal-loop (HTL) perturbation theory, and the strongly coupled one is treated based on the holographic approach. In more realistic setups, the feasibility of observing the optical phenomenon related to the RI of QGP is also discussed.

Soot in Cretaceous-Paleogene boundary clays worldwide: is it really derived from fossil fuel beds close to Chicxulub?
Authors: Premović Pavle 
Published: June 2012

Abstract
High soot contents have been reported in Cretaceous-Paleogene boundary (KPB) clays worldwide. One of the interpretations suggests this material comes from combustion of fossil fuels such as crude oil, coal or oil shales near the Chicxulub impact site. Combustion was triggered by the KPB impactor. In this Note, I show that the estimated mass of crude oil (or fossil hydrocarbons in general) burned (ca. 1017–1019 g), based on the average amount of soot (0.0022–0.012 g cm−2) or elemental carbon (0.011 g cm−2) found at the marine KPB sites, contradicts the fossil hydrocarbons hypothesis.

Published: June 2012

Background High sex ratios at birth (SRB) are seen in China, Taiwan, South Korea, parts of India and Vietnam. The imbalance is the result of son preference, accentuated by declining fertility. Prenatal sex determination and female feticides are common in many countries. It is reflected in sex ratio Objective To determine reasons for the preferences for different sex; to find out whether there is altered sex ratio at birth and to find out whether female feticide are common among women who had abortion. Method It is a prospective study. Women who had previous history of abortion and had delivered at Patan Hospital in the year 2066 were interviewed as per questionnaires. Results Among 560 women with total live births of 965, (462 male and 503 female) during their life time the overall sex ratio was 92 male per 100 female birth; total abortions were 663. Preferences for male were 10%, female 15.4% and either was for 74%. The reason for male preference was to continue family lineage, to bring honor, old age security, and performing funeral rites while the reasons for daughter preferences were that they understand mother’s pain, help in household work. The sex ratio of the babies born during the study period was 113 male per 100 female births. The Sex ratio at birth from 1st to 6th deliveries was 61, 79, 101, 210, 286 and 1100 male per 100 female birth respectively. Prenatal sex selection was 8% (by USG) but none had sex selected abortion. ConclusionSex ratio of those delivered during the study period was skewed (136 boys per 100 girls) towards male. There was shift in SRB in 4th and subsequent pregnancies in favor of boys. As the male sex ratio increased the number of induced abortion decreased in subsequent pregnancies.DOI: http://dx.doi.org/10.3126/kumj.v9i4.6334 Kathmandu Univ Med J 2011;9(4):229-232

Published: June 2012

Background Smoking among health care personnel such as medical students is an important public health issue. More effective measures to reduce tobacco smoking among medical students are needed worldwide. Very few studies had been conducted in past in India and other developing countries to understand the magnitude of problem. Objectives To determine the prevalence and associated factors of current smoking among medical students. Methods Cross sectional study was conducted during January and February 2009 among 333 study subjects selected randomly from four batches of a teaching institution. Subjects were administered a self administered pre tested questionnaire and smoking status was assessed as per the criteria laid down by WHO. Proportion, chi square test and multiple logistic regression analysis were used for statistical analysis. Results The prevalence of current smoking was found to be 22.4% (67). There were widespread deficiencies in knowledge of smoking among students of different classes, as an important causal factor in many diseases like gastro intestinal malignancy, heart problems, asthma, and emphysema. It was found that only half of them were willing to quit smoking (33). Fourth year students (OR=2.54) and presence of peer pressure (OR=21.91) had independent significant association with current smoking. Conclusion Prevalence of smoking among medical students is high that warrants adoption of comprehensive smoking control interventions among them.DOI: http://dx.doi.org/10.3126/kumj.v9i4.6335 Kathmandu Univ Med J 2011;9(4):233-7

Authors: Shrestha G S , Marhatta M N , Amatya R 
Published: June 2012

Background Laryngoscopy and intubation increases blood pressure and heart rate. Objective The study aims to investigate the effect and safety of gabapentin, esmolol or their combination on the haemodynamic response to laryngoscopy and intubation. Methods A total of 72 patients undergoing elective surgery were randomly allocated to one of the four groups. First study drug was administered orally as gabapentin 1200mg or placebo. Second study drug was administered intravenously as esmolol 1.5mg/kg or normal saline. Heart rate, rate pressure product, systolic blood pressure and mean arterial pressure were recorded at baseline and at zero, one, three and five minutes after tracheal intubation. Results Baseline values were compared with the values at various time intervals within the same group. In group PE (placebo, esmolol), there was significant decrease in heart rate and rate pressure product at five minutes. In group GN (gabapentin, normal saline), there was significant decrease in systolic blood pressure and mean arterial pressure at five minutes. In group GE (gabapentin, esmolol), there was significant decrease in heart rate at zero, three and five minutes. Systolic blood pressure, mean arterial pressure and rate pressure product was significantly lower at three and five minutes. In group PN (placebo, normal saline), there was significant increase in heart rate at zero, one, three and five minutes; systolic blood pressure at zero and one minutes; mean arterial pressure at zero and one minutes & rate pressure product at zero, one and three minutes. In group GN (gabapentin, normal saline), there was significant increase in heart rate at zero, one and three minutes & rate pressure product at zero, one and three minutes. In group PE (placebo, esmolol), there was significant increase in systolic blood pressure at zero and one minutes & mean arterial pressure at zero and one minutes. However, in group GE (gabapentin, esmolol) none of the variables showed statistically significant increase at any time. Inter-group comparison was made for each time point. At zero minute, there was significant difference in heart rate between groups PN and GE, GN and PE & GN and GE Significant difference was also noted in rate pressure product between PN and GE at zero minute. At one minute there was difference in heart rate between PN and PE, PN and GE, GN and PE & between GN and GE. Significant difference was observed in rate pressure product between PN and PE & between PN and GE at one minute. No significant side effects of the study drugs were observed. ConclusionsCombination of gabapentin and esmolol in this study design is safe and better attenuates both the pressor and tachycardic response to laryngoscopy and intubation, than either agent alone.DOI: http://dx.doi.org/10.3126/kumj.v9i4.6336 Kathmandu Univ Med J 2011;9(4):238-43

Published: June 2012

Background Stroke is usually end result of predisposing conditions that originated years before the ictus. Identification of its modifiable risk factors can help in planning preventive strategies. Objective To study the risk factors of stroke in adult patients. Methods A hospital based prospective cross sectional study was carried out in 160 stroke patients admitted in Manipal Teaching Hospital, Pokhara from November 2007- October 2010. Diagnosis of stroke was confirmed by CT scan of brain. Patients were then investigated for presence of conventional risk factors. The data was statistically analysed using Epi-Info. Results The mean age of stroke patients was 65.98 years ± 10.69 with 126 (78.8%) of patients belonging to age group ? 60 years. It afflicted higher percentage of males 104 (65%) than females 56 (35%). Analysis of stroke subtypes showed preponderance of haemorrhagic stroke in 85 (53.1%) as against infarction in 75 (46.9%) of cases. Other conventional modifiable risk factors were seen as follows: hypertension 98 (61.2 %), cigarette smoking 95 (59.4%), alcohol use 43 (26.9%), left ventricular hypertrophy 44 (27.5%), atrial fibrillation 37(23%), elevated triglyceride 37(23%), diabetes mellitus 15 (9.3%) and elevated total cholesterol 12 (7.5%). Multiple risk factors (? 2) were seen in 122 (76.5 %) cases. ConclusionsThe maximum occurrence of stroke was seen in patients > 60 years. Overall male preponderance and higher occurrence of haemorrhagic stroke was seen in our study. Significant risk factors in order of descending order were hypertension, cigarette smoking, left ventricular hypertrophy, alcohol use, atrial fibrillation and elevated triglycerides.DOI: http://dx.doi.org/10.3126/kumj.v9i4.6337 Kathmandu Univ Med J 2011;9(4):244-7
C–reactive Protein and Early Mortality in Acute Ischemic Stroke
Authors: Dewan K R , Rana P V S 
Published: June 2012

Background There is growing evidence that inflammation plays an important role in atherogenesis. Several studies have shown that C-reactive protein (CRP), an inflammatory marker, is associated with stroke severity and outcome. But limited studies are there which show the relationship of CRP with early mortality i.e within seven days. Objective To study the association of CRP within 24 hours after acute ischemic stroke onset with severity during admission, types of ischemic stroke and outcome. Methods This cross sectional study was done including 100 consecutive cases of acute ischemic stroke admitted to Neurology center of College of Medical Sciences, Bharatpur (Chitwan), Nepal. The cases were classified as per TOAST classification and severity at admission assessed using National Institutes of Health Stroke Scale. C-reative protein (CRP) level was estimated by latex particle agglutination test. Result Thirteen percent patients expired by 7th day. In the expired group, CRP was positive in 15.3 percent, 15.3 percent and 61.5 percent in patients with lacunar, cardioembolic and large artery atherosclerotic infarction respectively (p 0.19). CRP was positive in all 7 patients (53.8%) who had expired with severe NIHS scale (p 0.004). ConclusionHigh CRP level is associated with stroke severity at admission and is an independent predictor of early seven day mortality after ischemic strokeDOI: http://dx.doi.org/10.3126/kumj.v9i4.6339 Kathmandu Univ Med J 2011;9(4):252-5
