Prevalence of Salmonella typhi and intestinal parasites among food handlers in Bahir Dar Town, Northwest Ethiopia.

Background: Food borne diseases are a global public health problem. Food handlers play a major role for the transmission of food borne diseases. Objectives: This study was aimed at exploring the prevalence of intestinal parasites, S. typhi carrier rate and risk factors among food handlers at Bahir Dar town. Methods: A cross -sectional survey was conducted among food handlers working in different kitchens. A pre-tested structured questionnaire was used for collecting data. Stool samples were investigated for intestinal parasites and S. typhi as per the standard laboratory methods. Results: Among 384 food handlers, females comprised 300 (78%). The majority 371 (96.6%) were young adults (12-40 years). The median year of service was 1 year (1 month to 24 years). All food handlers had no previous medical checkup and 54 (14%) were certified as food handlers. One hundred fifty eight (41.1%) food handlers had intestinal parasites and 6 (1.6%) were found positive for S. typhi. Of these, 25 (6.5%) were suffering from diarrhoea. Nine species of intestinal parasites, 2 protozoa (E. histolytica/dispar 12.76% and G. lamblia 7. 0%) and 7 helminthes (A. lumbricoides, 11.7%, Hookworm, 8.1%, S. stercoralis, 2.86%, S. mansoni, 1.8%, Taenia species, 1.3%, H. nana, 0.5% and T. trichiuria, 0.5%) were detected. Conclusion: Inexperienced and poor personal hygienic food handlers play a role for transmission of food borne infections. Local health authorities should implement food handler’s training on food safety, institute periodic focused medical check up for food handlers and improve human waste disposal. [Ethiop. J.

A Guide to Applying the Sex-Gender Perspective to Nutritional Genomics

Precision nutrition aims to make dietary recommendations of a more personalized nature possible, to optimize the prevention or delay of a disease and to improve health. Therefore, the characteristics (including sex) of an individual have to be taken into account as well as a series of omics markers. The results of nutritional genomics studies are crucial to generate the evidence needed so that precision nutrition can be applied. Although sex is one of the fundamental variables for making recommendations, at present, the nutritional genomics studies undertaken have not analyzed, systematically and with a gender perspective, the heterogeneity/homogeneity in gene-diet interactions on the different phenotypes studied, thus there is little information available on this issue and needs to be improved. Here we argue for the need to incorporate the gender perspective in nutritional genomics studies, present the general context, analyze the differences between sex and gender, as well as the limitations to measuring them and to detecting specific sex-gene or sex-phenotype associations, both at the specific gene level or in genome-wide-association studies. We analyzed the main sex-specific gene-diet interactions published to date and their main limitations and present guidelines with recommendations to be followed when undertaking new nutritional genomics studies incorporating the gender perspective.
MCMC-Based Detection for Random Access With Preambles in MTC

Random access has been considered for machine-type communication (MTC). In particular, a random access scheme with a pool of preambles is widely studied, which is similar to multichannel ALOHA, to support a number of MTC devices. In this paper, we study optimal approaches for user activity detection in random access with preambles over fading channels. Since the computational complexity grows exponentially with the number of preambles, a low-complexity detector is derived using Markov chain Monte Carlo (MCMC) approaches that can approximately solve an optimal maximum a posteriori detection problem. The resulting MCMC detector can enjoy a trade-off between performance and complexity, while its complexity to obtain a sample is linearly proportional to the number of preambles. A performance analysis for optimal detection is also studied to see the optimal performance. Simulation results confirm that the MCMC detector performs better than compressive sensing-based approaches and can provide a near optimal performance under certain conditions with a reasonable computational complexity.
Feedback and Key Discrimination on Membrane Keypads

This study investigated the effects of visual and tactile key discrimination and kinesthetic and auditory feedback on membrane keypads. More specifically, metal domes, embossed key edges and tone were examined. Fortyeight subjects were used in a 2 × 2 × 2 factorial design with two levels of key discrimination (with and without embossed key edges), two levels of kinesthetic feedback (with and without metal domes), and two levels of auditory feedback (with and without a 1000 Hz tone). Several types of preference scales along with keying time and error rate were used as comparative measures. Results indicated that key discrimination provided by embossed key edges and feedback provided by metal domes and auditory tones had significant effect on keying performance and operator ratings of membrane keypads. Auditory feedback paired with tactile and/or kinesthetic feedback yielded the best performance and preference scores.
The Role of Self-Compassion Factors in Predicting the Marital Satisfaction of Staff at Kermanshah University of Medical Sciences

Introduction: Marital satisfaction is one of the effective factors in job satisfaction. Therefore, the present study aimed to investigate the role of selfcompassion factors in predicting the marital satisfaction of staff at Kermanshah University of Medical Sciences. Material and Methods: In this descriptive, correlational and analytical study, the statistical population consisted of all staff at Kermanshah University of Medical Sciences, of which 280 staff (140 males and 140 females) were selected from both morning and evening shifts through convenience sampling according to the inclusion and exclusion criteria. Further, for data collection, a demographic questionnaire, the Enrich marital satisfaction scale and Neff self-compassion scale were utilized. Then data were analyzed through the descriptive and inferential statistics in the SPSS Statistics Software Version 21.0. Results: The results of the present study revealed that marital satisfaction correlated with self-kindness (0.89), common humanity and mindfulness (0.89), isolation (-0.85) and over-identified items (-0.42) (p<0.01). The results of regression analysis also demonstrated that the items of self-kindness (β=0.89), common humanity and mindfulness (β=0.45) and isolation (β=0.37) could predict marital satisfaction, while the over-identified items could not (β=0.04). Conclusion: Some effective steps can be taken towards improving marital satisfaction among staff using the results of studies and their application in relations between spouses, thereby resulting in satisfaction with life, improved quality of life, and job satisfaction.
Estrogen receptor co-regulators as prognostic and predictive markers of endocrine therapy in early breast cancer: the role of SMRT and p160 family

Background: The estrogen receptor (ER) signaling pathway is the dominant driver of cell proliferation and survival in the majority of human breast cancers. Not surprisingly, endocrine treatment, such as the anti-estrogen tamoxifen, represents the most effective and widely used therapy for ER positive breast cancer patients. Unfortunately not all patients respond to endocrine treatment and a wide proportion of patients ultimately develop resistance and die. Selecting patients with an increased risk of recurrence and identifying those that might benefit from a particular therapy is of great value in order to personalize breast cancer therapies. A minority of breast cancers does not express ER and displays features of aggressiveness and poor prognosis. Prognostic markers are urgently needed for this subset of patients as well. The p160 family of ER co-activator is composed of three different members: SRC1, SRC2 and AIB1. SRC1 and AIB1 are frequently overexpressed in breast cancer and appear to be linked to hormone resistance, particularly in HER2 positive breast cancer. SMRT is an ER co-repressor that has been implicated in tamoxifen resistance. Data on p160 family members and SMRT expression in human breast cancer samples and its prognostic and predictive significance in endocrine treated patients are controversial or lacking altogether. Moreover, the role of these co-regulators in ER negative disease is poorly understood. Methods: SRC1, SRC2, AIB1 and SMRT expression was determined by immunohistochemistry on tissue microarrays derived from two fully documented cohorts of 1812 and 1424 patients. Results: HER2 and AIB1 dual-positive tumors were associated with markedly worse outcome compared to tumors overexpressing either HER2 or AIB1 alone, irrespective of ER status. In ER negative disease both SRC1 and AIB1 were linked to early relapse and death. Additionally, we found that co-expression of two or more SRCs were significantly associated with worse outcome in ER positive endocrine-treated patients. However, expression of any SRC alone was not a significant predictor of resistance to endocrine therapy. Low nuclear SMRT expression was associated with a significantly better outcome in untreated patients but not in tamoxifen-treated patients. Conclusions: The SRC family of ER co-activators and nuclear SMRT are markers of early relapse in both ER negative and ER positive breast cancer. Evaluation of multiple markers co-expression (i.e. AIB1/HER2, multiple SRCs) rather than single markers allows a better assessment of breast cancer prognosis.
Predictors of Nursing Home Admission for Older Black Americans

Abstract This study examines the assumption that including Black-Americans with larger samples of White-Americans produce an accurate picture of the predictors of nursing home use by Black-Americans. Using the Longitudinal Study of Aging (1984-1990), Cox proportional hazard models are estimated for Black-Americans and White-Americans. This study finds that in fact the models for Black-Americans are not the same as for White-Americans. For Black-Americans, living below the poverty line, problems of functional status, age, and not having the potential for care for a few weeks from relatives (in or out of the home) are predictive of a higher risk of nursing home use while, for White-Americans, age, lower versus higher income, being female versus male, poor evaluation of self health care, poor functional status, lower levels of community activity, and living alone compared to living with a spouse or children were predictive of a higher risk of nursing home admission. The implications for policy and case manag.
Current Treatment Options for Human Epidermal Growth Factor Receptor 2-Directed Therapy in Metastatic Breast Cancer: An Indian Perspective

Abstract Human epidermal growth factor receptor 2 (HER2)-positive is an aggressive subtype of breast cancer and has historically been associated with poor outcomes. The availability of various anti-HER2 therapies, including trastuzumab, lapatinib, pertuzumab, and trastuzumab emtansine (TDM-1), has remarkably improved the clinical outcomes in patients with HER2-positive metastatic breast cancer (mBC). However, there is a need to optimize treatment within this population, given the wide variability in clinical presentation. Additionally, geographical and socio-economic considerations too need to be taken into account. To clarify and collate evidence pertaining to HER2-positive metastatic breast cancer, a panel of medical and clinical oncologists from across India developed representative clinical scenarios commonly encountered in clinical practice in the country. This was followed by two meetings wherein each clinical scenario was discussed in detail and relevant evidence appraised. The result of this process is presented in this manuscript as evidence followed by therapeutic recommendations of this panel for management of HER2-positive mBC in the Indian population.
Reconstructing the spatio-temporal traffic dynamics from stationary detector data

We present a new method to obtain spatio-temporal information from aggregated data of stationary traffic detectors, the "adaptive smoothing method". In essential, a nonlin-ear spatio-temporal lowpass filter is applied to the input detector data. This filter exploits the fact that, in congested traffic, perturbations travel upstream at a near-constant speed, while in free traffic, information propagates downstream. As a result, one obtains velocity, flow, or other traffic variables as smooth functions of space and time. Applications include traffic-state visualization, reconstruction of traffic situations from incomplete information, fast identifica-tion of traffic breakdowns (e.g., in incident detection), and experimental verification of traffic models, and even a short-term traffic forecast. We apply the adaptive smoothing method to observed congestion patterns on several German freeways. It manages to make sense out of data where conventional visualization techniques fail. By ignoring up to 65 % of the detectors and applying the method to the reduced data set, we show that the results are robust. The method works well if the distances between neighbouring detector cross sections do not exceed 3 km.
An evaluation of the metabolic effects of antipsychotic medications in patients suffering from psychiatric illness

Article history: Received on: 23/01/2014 Revised on: 17/02/2014 Accepted on: 11/03/2014 Available online: 28/04/2014 Present study evaluates the effects of antipsychotic medications on metabolic parameters in patients suffering from psychiatric illness. The study was carried out at tertiary care teaching hospital, department of psychiatry after obtaining written informed consent from the patients. They were randomized into three groups Group I (n=31) (haloperidol 10 mg/day, orally), Group II (n=34) (risperidone 4-6 mg/day, orally) and Group III (n=38) (olanzapine 10 mg/day, orally). Metabolic parameters [fasting blood sugar (FBS), post prandial blood sugar (PP2BS), glycosylated haemoglobin (HbA1c), serum cholesterol, triglyceride, low density lipoprotein (S.LDL) and high density lipoprotein (S.HDL)] were measured at the end of 3 and 6 months. Data was analysed using a suitable statistical tests. In group II significant changes (p<0.05) were observed in FBS, HBA1C, cholesterol, S.LDL and S.HDL while in group III significant changes (p<0.05) were observed in all the metabolic parameters at the end of 6 months. In group III, FBS, PP2BS, HbA1C, Serum cholesterol, triglyceride and S.LDL levels were increased 9.41%, 7.09%, 8%, 6.25%, 7.68% and 9.92% respectively, at the end of 6 months. Patients treated with haloperidol showed minimum changes in metabolic parameters at the end of 6 months. Olanzapine is associated with more disturbances in metabolic parameters as compared to risperidone and haloperidol.
Stage-Dependent Efficacy of Intra-arterial Fibrinolysis in Central Retinal Artery Occlusion (CRAO)

Background: To find indications for intra-arterial fibrinolysis of CRAO. Method: A total of 46 patients with CRAO were treated with intra-arterial fibrinolysis (IF) using a microcatheter. The signs of CRAO were allotted to three different stages: I. incomplete CRAO; II. subtotal CRAO; III: CRAO with choroidal hypoperfusion (or with choroidal infarction). Results: Of the 46 patients treated with IF, 11 (24%) recovered their vision completely or showed a marked improvement after IF, and 17 (37%) showed a partial improvement. No remarkable changes were observed in 14 patients (30.4%), while visual acuity deteriorated in four patients (8.7%). In 30 of 46 patients (65.2%), urokinase was administered into the ophthalmic artery; in nine patients (19.6%), urokinase was injected into the internal maxillary artery (I Max); and in seven patients (15.2%), recombinant tissue plasminogen activator (r-TPA) was administered into the I Max. Almost all patients who showed a distinct or partial visual improvement were treat.
Effects of a mobile self-regulated learning approach on students’ learning achievements and self-regulated learning skills

Abstract The purpose of this study was to examine the effectiveness of the proposed mobile self-regulated learning approach in higher education settings. A mobile self-regulated learning system was developed to improve students’ learning achievements and self-regulated learning skills. An experiment was conducted to evaluate the effectiveness of the proposed approach by 60 undergraduates. The experiment group adopted the mobile self-regulated learning approach to read English passages, whereas the control group was not supported by the self-regulated learning mechanism while reading English passages. The results suggested that the mobile self-regulated learning approach significantly enhanced students’ learning achievements and self-regulated learning skills. Furthermore, it was found that the proposed approach did not increase students’ cognitive load. Participants also revealed that the mobile self-regulated learning system was very useful and effective according to the interview results and questionnaires.

Black Middle-class Masculinities in Postapartheid South Africa: Consumerism, Fashion and the Portrayal of Masculine Identities in Destiny Man Magazine

Abstract This article examines the state of middle-class black South African masculinity in the postapartheid era as presented in Destiny Man, a popular lifestyle magazine targeted at accomplished, stylish, and affluent black men in South Africa. The magazine offers a blend of compelling and relevant business and lifestyle content, including articles on fashion, grooming, sport, technology, and motoring. This article’s focus on consumerism, fashion, and masculinity as represented and featured in the magazine offers a vital contribution to fashion studies in general and to the African diaspora’s dress sense in particular, as well as to the contemporary intersections of wealth associated with masculine identification Articles published in the 2014 issues of the magazine were selected for an in-depth multimodal discourse analysis of how factors such as fashion, access to economic resources, status, and wealth play a significant role in masculine black identity formation. Visuals were also analysed to understand the representation of black middle-class men in the magazine. The findings indicate that Destiny Man’s characterization of middle-class black South African masculinity is based on the acquisition of material goods, on perceptions of power and on the ability to transition into formerly white-only spheres.
Security Analysis of Mobile Device-to-Device Network Applications

Mobile device-to-device (D2D) network has now become a standardized feature in many mobile devices, by which mobile devices can communicate with each other even when commercial Internet access is not available. Because D2D network is expected to be an intrinsic part of the Internet of Things (IoT) and mobile device is the smartest and the most advanced commercial device in everyday usage, the D2D feature and related security protocols it adopts influences the design and implementation of many other IoT devices. While D2D network provides tangible benefits to users, it also raises the security risks of information leaking. This paper presents an in-depth empirical security analysis on mobile D2D network among Android devices. Android apps could establish a mobile D2D network in various ways, including Wi-Fi hotspot, Wi-Fi Direct, and Bluetooth. Those mobile D2D protocols normally take different protection mechanisms, which makes security investigation considerably challenging. In this paper, we focus on most popular apps in the Google Play Store, with aggregated downloads more than 500 million. Our analysis reveals some critical vulnerabilities. The key findings are bi-fold. First, the current mobile D2D network framework enabled by Android has significant flaw of overprivilege issue. Second, we have identified that most data transfer over mobile D2D network is unencrypted. Furthermore, we exploit the identified Android framework flaws to construct three proof-of-concept attacks and we conclude this paper with security lessons and suggestions of possible solutions against the identified security issues.
