Female rats exhibit greater susceptibility to early alcohol-induced liver injury than males.

It is known that women develop hepatic injury more rapidly and with exposure to less ethanol than men; however, mechanisms remain unclear. The purpose of this study was to determine if an enteral alcohol delivery model could be used to study susceptibility of females to alcohol-induced liver injury. Male and female Wistar rats (age- or weight-matched) were given ethanol (11-12 g.kg-1.day-1) continuously for up to 4 wk via intragastric feeding, and control rats received a high-fat diet without ethanol. There were no significant differences in body weight among the groups studied. Furthermore, mean ethanol concentrations, their cyclic pattern in urine, and rates of ethanol elimination were also not different between the genders under these conditions. Ethanol treatment elevated serum aspartate aminotransferase levels in male rats to 126 +/- 10 IU/l after 4 wk. In females, however, values increased more rapidly and reached significantly higher values at 4 wk (168 +/- 18 IU/l). Steatosis, inflammation, and necrosis assessed histologically also developed more rapidly and were more severe in females than males. Steatosis due to ethanol exposure, which was localized in centrilobular areas in males, was panlobular in the female. Moreover, endotoxin in plasma, intercellular adhesion molecule 1 expression in hepatic sinusoidal-lining cells, and the number of infiltrating inflammatory cells in the liver were 2-2.5-fold greater in females than males. These changes possibly account for increased hepatic injury due to ethanol in the female.
Bayesian parameter inference for models of the Black and Scholes type

In this paper, we describe a general method for constructing the posterior distribution of the mean and volatility of the return of an asset satisfying dS=SdX for some simple models of X. Our framework takes as inputs the prior distributions of the parameters of the stochastic process followed by the underlying, as well as the likelihood function implied by the observed price history for the underlying. As an application of our framework, we compute the value at risk (VaR) and conditional VaR (CVaR) measures for the changes in the price of an option implied by the posterior distribution of the volatility of the underlying. The implied VaR and CVaR are more conservative than their classical counterpart, since it takes into account the estimation risk that arises due to parameter uncertainty.

Acanthamoeba meningoencephalitis in immunocompetent: A case report and review of literature

A 30-year-old manual laborer from Karnataka, India presented with intermittent low grade fever and diffuse headache for 1 month. On examination, patient had enlarged supraclavicular and cervical lymph nodes. Patient had positive Kernig′s sign and neck stiffness. Motor, sensory and cranial nerve examinations were within the normal limits. Abdominal, cardiovascular and chest examination did not yield any positive findings. Contrast enhanced computed tomography head was normal. Patient was suspected to have extrapulmonary tuberculosis. Patient was started on antitubercular drugs. Diagnostic lumbar puncture was performed. Wet mount and Giemsa smear preparation of cerebrospinal fluid (CSF) showed trophozoites suggestive of Acanthamoeba. CSF was cultured onto non-nutrient agar with an overlay of Escherichia coli. Wet mount made from the culture media yielded cysts and trophozoites of Acanthamoeba spp. Patient was diagnosed with Acanthamoeba meningitis and was started on specific therapy with Rifampicin 600 mg once a day, Cotrimoxazole 960 mg twice-a-day and Fluconazole 400 mg once daily for 2 weeks. Patient had a complete recovery and was discharged from the hospital.
Multislice helical CT of focal and diffuse lung disease: comprehensive diagnosis with reconstruction of contiguous and high-resolution CT sections from a single thin-collimation scan.

OBJECTIVE We tested breath-held 1-mm multislice helical CT for obtaining both contiguous and high-resolution CT sections of the chest from a single set of raw data. SUBJECTS AND METHODS Seventy patients with suspected focal and diffuse lung disease were allocated into two groups for comparison. The first group (n = 35) underwent multislice helical CT of the chest with 1-mm collimation and a pitch of 6. From the raw data, 5-mm contiguous and 1.25-mm high-resolution CT sections were reconstructed. The second group (n = 35) underwent conventional single-slice helical CT and high-resolution CT. High-resolution CT sections and 5-mm scans were rated for overall image quality, spatial resolution, subjective signal-to-noise ratio, diagnostic value, depiction of bronchi and parenchyma, and motion and streak artifacts. The 5-mm scans were also rated for contrast resolution and depiction of the heart and vessels. Radiation dose was calculated. RESULTS We rated 5-mm multislice helical CT superior to 5-mm single-slice helical CT, having a significantly higher total score (p = 0.0001). No significant difference (p = 0.986) was found between multislice and single-slice high-resolution CT sections. Radiation dose was 5.55 mSv for multislice helical CT and 5.50 mSv for single-slice helical CT. CONCLUSION Contiguous chest scans of superior quality and high-resolution CT sections of equal image quality compared with single-slice helical CT can be obtained using multislice helical CT. Therefore, a comprehensive diagnosis is feasible in patients with suspected focal and diffuse lung disease by obtaining a single scan.
Muscle size, activation, and coactivation in adults with cerebral palsy

Introduction: Muscle weakness is present in the paretic limbs of individuals with cerebral palsy (CP). We aimed to determine what neuromuscular factors contribute to weakness in adults with CP during isometric maximal voluntary contractions (iMVCs). Methods: Gastrocnemius anatomical cross‐sectional area (ACSA) and agonist and antagonist activation were measured in 11 CP and 11 control adult men during plantarflexion iMVC. Results: Plantarflexion iMVC torque of the paretic leg was 42% and 52% less than in the non‐paretic and control limbs, respectively. The paretic gastrocnemius ACSA was smaller than in the control group only. Paretic agonist activation was less than the non‐paretic and control groups, whereas antagonist coactivation was higher. Multiple regression analysis revealed muscle activation accounted for 57% of variation in paretic plantarflexion iMVC torque. Conclusions: In individuals with CP, muscle weakness in the paretic limb is attributed primarily to impaired neural activation and, to a lesser degree, ACSA. Muscle Nerve 49: 76–83, 2014
A Prospective, Randomized Trial of Tacrolimus in Combination with Sirolimus or Mycophenolate Mofetil in Kidney Transplantation: Results at 1 Year

Background. This is the 1-year report of a randomized, multicenter, clinical trial comparing the combination of sirolimus or mycophenolate mofetil (MMF) with tacrolimus-based immunosuppression in kidney transplantation. Methods. Prior to transplantation, recipients were randomized to receive tacrolimus plus corticosteroids with either sirolimus (n=185) or MMF (n=176). The incidence of biopsy-confirmed acute rejection at 6 months was the primary endpoint of the study. Patient and graft survival, renal function, study drug dosing and discontinuations were evaluated at 1 year. Results. At 1 year, there was no difference in patient survival (95.7% sirolimus vs. 97.2% MMF; P=0.45) or graft survival (90.8% sirolimus vs. 94.3% MMF; P=0.22). Patients without delayed graft function (DGF) receiving MMF had significantly better graft survival (99% vs. 93%; P=0.01). Patients receiving a transplant from a live donor had a trend towards better graft survival with MMF as compared to sirolimus (98% vs. 91%; P=0.07). Patients receiving sirolimus had a significantly higher incidence of study drug discontinuation (26.5% vs. 14.8% MMF; P=0.006). Patients receiving MMF had significantly better renal function as shown by median serum creatinine levels (1.3 mg/dL vs. 1.5 mg/dL; P=0.03) and a trend towards higher calculated creatinine clearance (CrCl), (58.4 ml/min vs. 54.3 ml/min; P=0.06). More patients in the sirolimus group had a serum creatinine >2.0 mg/dL, (20.4% vs. 11.0%; P=0.02). Conclusions. Tacrolimus is safe and effective in live and deceased donor kidney transplantation when given in combination with sirolimus or MMF. Patient and graft survival were excellent in both arms. Renal function is superior for patients treated with tacrolimus + MMF combination.
Auditors' going‐concern judgments: rigid, adaptive, or both?

Purpose - The purpose of this paper is to examine when auditors' decision behavior is rigid and adaptive in the going-concern judgment. Because rigid behavior has been found to produce inappropriate outcomes, understanding when decision behavior is rigid or adaptive can lead to improved decision making. Design/methodology/approach - An experiment is conducted using cases based on real companies to produce information search traces as dependent measures that are studied in the ill-structured and structured parts of the going-concern task. Findings - Auditors are adaptive in ill-structured tasks and rigid in structured tasks as predicted by theory. Evidence of flawed decision making commonly found in studies of fixation and related concepts was not found. Research limitations/implications - The findings suggest the importance of explicitly accounting for task structure when studying decision behavior in situated contexts. Future research could assess whether task structure similarly impacts behavior in non-auditing contexts. Practical implications - Researchers and practitioners have long been concerned about inappropriate rigid behavior. This paper helps practitioners better understand when rigid or adaptive behavior is likely to occur to improve decision making. Originality/value - Taking a novel approach to reconcile two well established but conflicting bodies of literature by focusing on “when” not “whether” people are rigid or adaptive, this paper resolves a long-standing paradox. The implication for the literature is that reframing the question and directly measuring behavior demonstrates that individuals are neither rigid nor adaptive, but can be both as they follow behavior that is consistent with the demands of the task when the demands are defined in terms of task structure.
The Vietnam Provincial Competitiveness Index 2005

Funded by US-AID, Provincial Competitiveness Index (PCI) is an effort to explain why some parts of the country perform better than others in terms of private sector dynamism, job creation and economic growth. Using new survey data from businesses that describe their perceptions of their local business environments, as well as credible and comparable data from official and other sources regarding local conditions, the PCI rates provinces on a 100-point scale. In 2005, the overall index is comprised of nine sub-indices that explain much of the variation in performance across provinces in Vietnam. In 2006, two new sub-indices were developed to capture other aspects of Provincial Government efforts to enhance the business environment. In addition, a number of the existing indices were strengthened by modifying certain indicators. Sub-indices and indicators are described in detail under the caption “PCI Sub-Indices” below.The research has a number of important design elements that make the results easily translated into governance reforms:First, by separating out the growth that is generated by initial conditions (i.e. the fundamental underlying factors that contribute to growth but that are very difficult or impossible to address in the short-term), the research was able to determine that good governance practices are possible at the provincial level and that these practices explain why some areas outperform others or why some areas have similar economic outcomes despite having very different initial conditions. The focus on governance practices should lead to improvements in economic performance, even without significant changes in the physical and human infrastructure in a region.Second, by normalizing the scores around the best practices already found in Vietnam, the index directs provincial governments to improve their performance, not against some ideal standard of good governance but rather against the best performance already practiced by their peers within the same national political framework. Therefore, any province in theory could attain a perfect score by adopting the best practices already found in Vietnam. The implication is that there are no easy explanations for poor performance – every provincial government can do better to generate a more favorable economic environment within their borders.Third, by comparing governance practices against actual economic performance, the PCI provides initial estimates of how important governance practices are to attracting investment and generating growth. The research provides a compelling demonstration of the association between business-friendly governance practices, business responses and, importantly, welfare improvements. This last connection is critical as it makes clear that business-friendly policies and practices benefit not just entrepreneurs but also the broader society that relies upon private sector dynamism to provide the jobs that raise household living standards.Research results from the work of the Vietnam Competitiveness Initiative and the Vietnam Chamber of Commerce and Industry.
Human polymorphonuclear leukocytes lack detectable nitric oxide synthase activity.

Nitric oxide regulates polymorphonuclear leukocyte (PMN) function, but whether or not human PMNs express nitric oxide synthase (NOS) activity is controversial. We studied NOS activity in human PMNs by using human aortic endothelial cells (HAECs) for comparison. The conversion of L-arginine to L-citrulline, a relatively specific measure of NOS activity, was easily measured and inducible in fractionated HAECs, and > 90% of all L-arginine conversion was blocked by the NOS inhibitor, N omega-amino-L-arginine (L-NAA). In fractionated PMNs, L-arginine conversion was low and was unaffected by L-NAA. In addition, NOS activity was not induced in PMNs by LPS, IL-1 beta, or IFN-gamma. In a whole-cell assay, total L-arginine conversion was much lower in human PMNs compared with HAECs (3.38 +/- 0.21 vs 157.5 +/- 10.28 pmol/h/10(6) cells, respectively; p < 0.01). This conversion in whole PMNs was not increased in vitro by LPS, IFN-gamma, IL-1 beta, or TNF-alpha nor decreased by W13, a calmodulin inhibitor. Furthermore, PMNs isolated from four volunteers before and after challenge with i.v. LPS (4 ng/kg) showed no increase in L-arginine to L-citrulline conversion. Nitrite and nitrate release from human PMNs was 35-fold lower than for HAECs and was not inhibited by L-NAA. These data suggest that human PMNs do not express NOS activity.
Adoption of integrated water resources management principles and its impacts: lessons from Ferghana Valley

The Ferghana Valley Project, initiated in 2001, has promoted institutional change in the post-Soviet irrigation sector in this part of Kyrgyzstan, Tajikistan and Uzbekistan. This paper presents the short-term (5-year) impacts of integrated water resources management project activities focused on water user participation in the South Ferghana Canal of Ferghana Province in Uzbekistan on irrigation water delivery and crop productivity. Irrigation performance assessment indicators indicate only slight improvements in water delivery and crop yields. Although water was important, larger changes in the agricultural sector of Uzbekistan dominated outcomes in this relatively short time span.
Unappreciated epidemiology: the churn effect in a regional HIV care programme

High levels of geographic mobility in and out of HIV care centres (i.e. the churn effect) can disrupt the continuity of patient care, misalign prevention services, impact local prevalence data perturbing optimal allocation of resources, and contribute to logical challenges in repeated transfer of health records. We report on the clinical, demographic, and administrative impact of high population turnover within HIV populations.
Clinicopathologic Features of Ameloblastoma in Kenya: A 10-Year Audit

This study describes the clinical and pathologic features of ameloblastomas seen in the 2 main craniofacial treatment centers in Kenya in the 10-year period between January 1995 and December 2005. A total of 184 patient records were analyzed for this study. Eighty-two (44.6%) of the patients were male, and 102 (55.4%) were female with an overall age range of 10 to 80 years (mean, 30.2 years; SD, 14.1 years). There was no significant difference in gender presentation of ameloblastomas, although females presented at a slightly older age. The mean age for males was 29.9 years, and for females, it was 30.5 years. Patients generally tended to seek medical advice late, with the mean duration at first presentation of 46.3 months for males and 44.4 months for females. Most of the ameloblastomas (n = 172; 93.5%) were located in the mandible, 11 (6.0%) were in the maxilla, and 1 (0.5%) was in the soft tissues. Presenting symptoms included swelling (n = 182; 98.9%), pain (n = 64; 36.0%), mobile teeth/history of extraction (n = 104; 57.5%), purulent discharge (n = 39; 21.7%) and paresthesia (n = 10; 5.6%). The posterior mandible was the most commonly affected site, whereas maxillary ameloblastomas tended to occur in anterior sites. One hundred fifty-three ameloblastomas (83.2%) were of the solid/multicystic subtype; 8 (5.3%) were unicystic; 1 (0.5%) was of extraosseous origin; 1 (0.5%) was desmoplastic; 9 (6.0%) were malignant, and 12 of the records had no histopathologic pattern specified.
Do Underwriters Certify Value? Evidence from UK Rights Issues and Open Offers

Eckbo and Masulis (1992) and Slovin, Sushka and Lai (2000) have proposed that underwriters of seasoned equity offers certify issuer value. The study tests predictions resulting from these papers and finds little evidence from UK rights issues and open offers that underwriting banks certify. The main purpose of underwriting appears to be simply to guarantee the proceeds. There is a positive reaction to open offers (a type of private placing) but this is unlikely to be due to underwriter certification. There is a large loss of value for companies announcing deeply discounted offers, which is attributed to release of bad news on announcement Copyright Blackwell Publishers Ltd 2002.
Interleukin-18 as a Predictor of Future Events in Patients With Acute Coronary Syndromes

Objective—The aim of this study was to assess the short- and long-term prognostic significance of interleukin-18 (IL-18) levels in patients with acute coronary syndromes (ACS). Methods and Results—In patients hospitalized with ACS (median age, 66 years; 30% females), we evaluated associations of serum IL-18 levels from day 1 (n=1261) with the short- (<3 months) and long-term (median, 7.6 years) risk of death, development of congestive heart failure (CHF), and myocardial infarction (MI). IL-18 was not significantly associated with short-term mortality. In the long term, IL-18 levels were significantly related to all-cause mortality, even after adjustment for clinical confounders (hazard ratio [HR], 1.19; 95% confidence interval, 1.07 to 1.33; P=0.002). Long-term, cardiovascular mortality was univariately related to IL-18, and the adjusted relation between noncardiovascular mortality and IL-18 was highly significant (HR, 1.36; 95% confidence interval, 1.11 to 1.67; P=0.003). IL-18 independently predicted CHF, MI, and cardiovascular death/CHF/MI in both the short and long term. Measurements from day 1 of ACS and 3 months after ACS had a similar power to predict late outcome. Conclusion—The addition of the measurement of IL-18 to clinical variables improved the prediction of risk of all-cause and noncardiovascular mortality. The association between IL-18 and noncardiovascular mortality is intriguing and warrants further study.
Infection with high‐risk HPV types among female sex workers in northern Vietnam

Vaccines against two high‐risk human papillomavirus (HPV) types, HPV‐16, and HPV‐18, are in use currently, with high efficacy for preventing infections with these HPV types and consequent cervical cancers. However, circulating HPV types can vary with geography and ethnicity. The aim of this study was to investigate the prevalence of HPV types and the association between HPV types and abnormal cervical cytology among female sex workers in Northern Vietnam. Cervical swabs and plasma samples were collected from 281 female sex workers at two health centers in Hanoi and Hai Phong in 2009. The HPV L1 gene was amplified by PCR using original and modified GP5+/6+ primers. Amplified PCR products were genotyped by the microarray system GeneSquare (KURABO) and/or clonal sequencing. Of the 281 women, 139 (49.5%) were positive for HPV DNA. Among the HPV‐positive samples, 339 strains and 29 different types were identified. Multiple‐type and high risk‐type HPV infections were found in 85 (61.2%) and 124 (89.2%) women, respectively. The most common genotype was HPV‐52, followed by HPV‐16, HPV‐18, and HPV‐58. Abnormal cervical cytology was detected in 3.2% (9/281) of the women, and all of these samples were positive for HPV‐DNA. Age ≤25 years and infection with human immunodeficiency virus were associated positively with HPV infection among the women while ever smoking was associated negatively. These results show that HPV‐52 is most prevalent among female sex workers in Northern Vietnam, most of whom had normal cervical cytology. This information may be important for designing vaccination strategies in Vietnam. J. Med. Virol. 85:288–294, 2013. © 2012 Wiley Periodicals, Inc.
Readmission to the intensive care unit after liver transplantation

ObjectiveWe undertook this study to understand the factors at our transplant center that contribute to patients’ return to the ICU after their liver transplant and their initial discharge from that unit. Patients who, after liver transplantation, fail discharge from the Intensive Care Unit (ICU) and must be readmitted to that unit may well utilize many more resources than those patients who are well enough to stay out of the ICU. DesignA retrospective review of a prospectively maintained liver transplant research database followed by a retrospective review of (a subgroup) patient charts and contemporaneous controls. SettingA large metropolitan tertiary care center and adult liver transplant center. PatientsA total of 1,197 consecutive adult patients who underwent their initial liver transplantation from 1984 to 1996. InterventionReadmission to the intensive care unit after adult liver transplantation and discharge from that unit. Main ResultsOnly recipient age, pretransplant synthetic function labs (protime and albumin), bilirubin levels, and intraoperative blood product requirements could be statistically linked to the group requiring ICU readmission. The primary etiology for ICU readmission was cardiopulmonary deterioration. Readmission was associated with significantly lower patient and graft survivals. A detailed review of 23 patients transplanted from October 1994 to June 1996 was made, with special emphasis on cardiopulmonary status (hemodynamics, respiratory variables, and chest radiograph findings). This subgroup was compared with 30 temporally matched controls who were not readmitted to the ICU. Intravascular fluid overload and lower inspiratory capacity were significant factors related to ICU readmission. Readmitted patients had a longer hospitalization with higher hospital charges than the control group. ConclusionsWe conclude that the most important means of preventing ICU readmission in liver transplantation patients is to optimize cardiopulmonary function and status. Close monitoring of fluid balance to avoid hypervolemia is essential. Readmitted patients have a greater resource utilization and have lower survival rates.
