Published: February 2020

Nowadays, developing contraception methods were mostly addressed to women. The development of male contraception was still limited. There were condoms, vasectomies, and interrupted intercourse, which used in male contraception. The condom method and interrupted intercourse have a high failure rate and inconvenience in its use. The vasectomy method is invasive and expensive. The development of molecular-based contraceptive methods with minimal impacts on health is expected to be a good breakthrough in the context of population control and improving the quality of health. The study aims to summarize and analyze the early development of contraception until the invention of molecular contraception through immunologic, proteomic, and metabolomics science. This article review was done by studying literature in the PubMed Central (PMC), Springer, and Open Access ScienceDirect databases. The search was performed with the keywords "Contraception", "Molecular Contraception", "Male Contraception", and "Immunocontraception". Journal articles that fit the theme of the review are then reviewed by paraphrasing the core of the research. The conclusion drawn from the review is that male contraception using the molecular method is still being developed at a pre-clinical experimental stage using animal laboratory technique and in vitro technique. The key to the success of this molecular method is that the more specific the molecular target at male fertility levels, the better of contraceptive effect. The molecular- based contraception is expected to be a breakthrough in terms of population control that have more effective, safe, and comfortable, especially for male contraception

Fault analysis is an important aspect in the successful operation of a power utility grid. The occurrence of faults in the system is not avoidable as causes of faults are not particularly one but of many with different causes and nature. It is one of the most important as well as it one of the most complex tasks in power engineering. The studies and discovery of faults in electric power systems is essential in ensuring the consistency and the stability if the power grid. Another importance of carrying out fault analysis gives a fair idea of the voltages and the current magnitudes under faulty conditions for different scenarios. This is helpful in the design of protection devices such as fuses, circuit breaker ratings, over current protection relays and other devices that are used for the protection of the system. Protection devices are important features of the power system grid mainly because their role in saving equipment and also human lives. In this paper, we investigate and analyze the behavior of electric power systems under fault conditions and then evaluate various practical scenarios.

Published: February 2020

Production cost is important in determining selling price and as a basis for management decision making to decide whether products manufacturing will be continued or discontinued. In addition, production cost has influence on firm’s profitability level; the smaller production cost, it will be inversely in proportion to its profitability.

The purpose of this study is to see how far the role of production cost affects profitability. By making some adjustments in production cost such as making efficiency, total number of the company’s profitability can be increased compared to production cost which is still high. The research done at PT Sakti Kandakawana, located in Bogor.

The result shows that PT Sakti Kandakawana is still be able to improve profitability by making some corrections on productionn cost. The assumption is the same number of selling will get higher profitability if it’s used lower production cost. Due to ineffective cost decreases more and more, the company has fund by efficiency without affecting products quality. 

Based on the evaluation, it shows that the production cost applied so far is still wasteful caused by raw materials used are expensive. In addition, it appears that cost for overtime work is not effective campare to cost for regular work. Thereby, when more efficient production cost is determined, the company’s profitability can be increased.

Evaluation of diagnostic utility of imprint cytology in paediatric renal tumours with special references to Ki 67 proliferative marker
Authors: Maity Namrata , Das Chhanda , Mukhopadhyay Madhumita , Parvin Tamanna , Saha Ashis Kumar , Mukhopadhyay Biswanath
Published: February 2020

BACKGROUND: Pediatric renal neoplasms comprise about 7%–8% of all neoplasms in children. Wilms tumour (WT) is the most common among pediatric renal tumours.

AIMS AND OBJECTIVES: The study was undertaken to study the epidemiological occurrence of pediatric renal tumours in a tertiary care hospital and to ascertain the validity and reliability of touch smear imprint cytology in intraoperative diagnosis of renal tumours and correlate with subsequent histopathological diagnosis and to assess the expression of proliferation marker Ki-67 in different components and stages of WT.

MATERIALS AND METHODS: It was a single-institution-based prospective and observational study, conducted for 2 years (from October 2013 to September 2015) in the department of pathology at our hospital. A total of fifty cases were enrolled in this study, all were below 15 years of age.

RESULTS: Imprint cytology showed sensitivity, specificity, and diagnostic accuracy of 83%, 98%, and 95.74%, respectively, in diagnosing benign and malignant renal tumours. There was statistically significant correlation of imprint cytology with confirmatory histopathological examination of excision specimen (P < 0.001). Immunohistochemical analysis of Ki-67 was done in all WT cases. Epithelial component had higher proliferative index than blastemal component with P = 0.0082, which was highly statistically significant.

CONCLUSION: Imprint cytology is found to be a less expensive, simple, and rapid method, which can be used as an adjunct to histopathology. Correlation between proliferation index as measured with Ki-67 antibody and tumour stage was found. Ki-67 is thus a relevant marker for assessing the proliferative activity.
Correlation of expression of aberrant immunophenotypic markers in T-ALL with its morphology: A pilot study
Authors: Garg Neha , Kotru Mrinalini , Kumar Dilip , Pathak Rajesh , Sikka Meera
Published: February 2020

INTRODUCTION: Aberrant expression of immunophenotypic markers is commonly found in patients of acute leukemia. T-ALL also shows aberrant markers such as CD13, CD33, CD117, CD10, and CD79a. Morphologically, T-ALL has been categorized into L1, L2, and L3 subtypes. Till now, no study has been done to correlate these markers with morphological features of T-ALL. This study aimed to correlate the expression of aberrant immunophenotypic markers with morphology in T-ALL.

MATERIALS AND METHODS: All the cases of T-ALL diagnosed by flow cytometry over a period of 2½ year were taken out from the records of Hematology Section of Department of Pathology of University College of Medical Science and Guru Teg Bahadur Hospital and Max Hospital, Saket. Their peripheral blood smear was screened to correlate the morphology of blasts with the expression of aberrant markers.

RESULTS: A total of 40 cases of T-ALL were identified during 2½ year period of our study. Morphological correlation was available for 23 cases. Aberrant expression of CD10 was present in 6 (35.3%) cases, CD79a in 9 (47.36%) cases, CD117 in 5 (42.28%) cases and myeloid antigen CD33 in 5 (38.46%) cases. CD117 and CD33-positive cases showed L2 morphology with the presence of convolutions, while cases with expression of CD79a had L1 morphology with absent-slight convolutions. CD10-positive cases had L1/L2 morphology with absent occasionally present convolutions.

CONCLUSION: There seems to be an association of aberrant markers with L1 and L2 morphology. However, this needs to be tested for statistical significance on a larger sample size.

Authors: Sultan Sadia , Irfan Syed Mohammed , Ali Navaira , Nawaz Neesha
Published: February 2020

BACKGROUND: Pakistan has a population of over 198 million making it the world’s sixth populous country. However, operational population-based cancer registries in Pakistan are lacking. Limited data are available based on institutional or Karachi Cancer Registry from Karachi; however, no exclusive registry for hematological malignancies is established till date. Hence, we decided to conduct a database analysis to determine the frequencies of various hematological cancers in our tertiary care center in Karachi.

PATIENTS AND METHODS: Retrospective assessment of 366 patients presented to Hematology Department, Liaquat National Hospital and Medical College from May 2012 to May 2016 with confirmed diagnosis of hematological cancers was performed. Data were retrieved from hospital-based tumor registry. All pro forma was filled by qualified medical research officer, which included demographic data as age, gender, history, disease type, and its stage at presentation.

RESULTS: Male gender was predominant and accounted for 69.9% (n = 256) and female accounted for 30.0% (n = 110) of the total cases with the male-to-female ratio of ~2:1. The mean ages of female and male patients were 42.9 ± 20.7 and 49.7 ± 18.1 years with the median age of 45 and 51.5 years, respectively. In males, the three most frequent malignancies were chronic myeloid leukemia (CML) (16%), acute lymphoblastic leukemia (ALL), and acute myeloid leukemia (AML) (12.8% of each). In females, AML was the most common cancer accounting for 21.8% followed by CML (18.1%) and ALL (10%).

CONCLUSIONS: Our institution-based tumor registry indicates CML and AML were the most common cancers in males and females, respectively, followed by ALL. Chronic lymphoid leukemia, unlike in the West, is seen infrequently in our population. National and provisional hematological tumor registry will be beneficial for future health planning and research.
Pattern of antimicrobial resistance of Gram-negative bacilli in surgical site infections in in-patients and out-patients at an apex trauma Center: 2013–2016
Authors: Bhardwaj Nidhi , Khurana Surbhi , Kumari Minu , Malhotra Rajesh , Mathur Purva
Published: February 2020

INTRODUCTION: Antimicrobial resistance is an increasing problem worldwide especially
among the surgical site infections (SSIs). SSI is becoming more serious due to hospital-acquired
infections/nosocomial infections, which further leads to the overuse of broad-spectrum antibiotics.
To investigate the antimicrobial resistance patterns among Gram-negative bacteria in SSI in in- and
out-patients the present study was designed.

METHODOLOGY: During the 4 years (January 2013–December 2016), the antimicrobial resistant
pattern was studied in the admitted patients and in the patients who were followed up to the outpatients
department (OPD) after discharge. Antimicrobial resistance pattern testing was done by the disk
diffusion method on Mueller-Hinton agar and by E-test for ten antibiotics according to The Clinical
and Laboratory Standards Institute guidelines for Gram-negative bacilli.

RESULTS: A total of 2,447 strains were isolated from the studied population on over the period of 4 years. Of 2447, 1996 (81%) were isolated from patients who had SSI during the hospital stay, and 451 (18%) were from patients who attended the OPD after discharge. In the outpatients, who followed up in the OPD for the SSI, Escherichia coli (148), and Pseudomonas aeruginosa (93), whereas in the patients who develop SSI during their hospital stay, Acinetobacter baumannii (622), E. coli (424), and Klebsiella pneumoniae (315) were found to be common. A very high resistance pattern was observed in both the studied groups; however, a higher resistance pattern was seen in in-patients as compared to outpatients.

CONCLUSION: In our study, we have reported resistance pattern in Gram-negative bacteria isolated from the patients who were came for the follow as well as in the inpatients. For the outpatients, it can be concluded that it could be a community-acquired infection which is also an alarming condition for our society.

Spatial Dependency in Nonstationary GEV Modelling of Extreme Precipitation over Great Britain
Authors: Wang Han , Xuan Yunqing
Published: February 2020

Abstract. This paper presents a study on extreme precipitation using both stationary and non-stationary Generalized Extreme Value (GEV) models over a large number of samples distributed over Great Britain (GB) for the last century, aiming to gain insights in the spatial dependency of the GEV distribution. Not only L-Moments (LM) and Maximum Likelihood (ML) estimation methods but a Bayesian Markov-Chain Monte Carlo (B-MCMC) method are incorporated into the GEV models to characterize the uncertainty in the nonstationary risk-based assessment. The samples are generated using a toolbox of spatial random sampling for grid-based data analysis (SRS-GDA). The results show that a markedly large proportion (70 %) of the samples are favour nonstationary assumption GEV models as far as the annual maximum daily rainfall (AMDR) is concerned. The most frequent AMDR, as represented by the location parameter tend to be increasing over the time for more than half of the samples and in contrast, only 8 % have a downward trend. A spatially clustering pattern is also clearly present. For rarer (with 0.1 probability) AMDR, they are shown to have a tendency of becoming more extreme over time, for more than half of the samples. For the three methods, the LM method with stationary GEV maintain best results but for AMDR values with higher probability (5-year return level); the B-MCMC method with nonstationary GEV, however, outperform other combinations by a large margin for more extreme events (50-year return level). The findings suggest that an overhaul of the current engineering design storm practice may be needed in view of environmental change impact on natural processes.
The whole is greater than the sum of its parts: a holistic graph-based assessment approach for natural hazard risk of complex systems
Authors: Arosio Marcello , Martina Mario L. V. , Figueiredo Rui
Published: February 2020

Abstract. Assessing the risk of complex systems to natural hazards is an important but challenging problem. In today's intricate socio-technological world,
characterized by strong urbanization and technological trends, the connections and interdependencies between exposed elements are crucial. These
complex relationships call for a paradigm shift in collective risk assessments, from a reductionist approach to a holistic one. Most commonly, the
risk of a system is estimated through a reductionist approach, based on the sum of the risk evaluated individually at each of its elements. In
contrast, a holistic approach considers the whole system to be a unique entity of interconnected elements, where those connections are taken into
account in order to assess risk more thoroughly. To support this paradigm shift, this paper proposes a holistic approach to analyse risk in complex
systems based on the construction and study of a graph, the mathematical structure to model connections between elements. We demonstrate that
representing a complex system such as an urban settlement by means of a graph, and using the techniques made available by the branch of mathematics
called graph theory, will have at least two advantages. First, it is possible to establish analogies between certain graph metrics (e.g. authority,
degree and hub values) and the risk variables (exposure, vulnerability and resilience) and leverage these analogies to obtain a deeper knowledge of
the exposed system to a hazard (structure, weaknesses, etc.). Second, it is possible to use the graph as a tool to propagate the damage into the
system, for not only direct but also indirect and cascading effects, and, ultimately, to better understand the risk mechanisms of natural hazards in
complex systems. The feasibility of the proposed approach is illustrated by an application to a pilot study in Mexico City.

El bienestar familiar adquiere importancia en la calidad de vida que una persona, familia o comunidad percibe. El ODS 3, relacionado con gozar de bienestar, es el centro del desarrollo humano. Al explorar la percepción de calidad de vida, se utilizó la escala QLI-Sp en una muestra de 1.810 participantes que representan a familias que residen en los 20 municipios salvadoreños que tienen salida al océano Pacífico. Se aplicó la técnica de encuesta utilizando el software de QuestionPro para dispositivos móviles. La data se trabajó en el software de SSPS 19 para analizar la información recabada. Entre los resultados se encontró que la calidad de vida percibida por las familias costeñas, en El Salvador, es deficiente porque no se superan, en más del 50 % de sus miembros, las condiciones intrínsecas y extrínsecas que facilitan la percepción de una buena salud. Al no satisfacer sus necesidades materiales, las estructuras que sostienen la pobreza como los bajos salarios, las ocupaciones laborales, el tipo de actividad productiva, la falta de tenencia de la tierra, la práctica de actividades colectivas que integran a la familia, la inseguridad comunitaria, el poco acceso a la información y los obstáculos financieros para invertir en producción económica limitan la percepción de un mejor bienestar psicológico y emocional, reportando una deficiencia en el bienestar emocional, intrapersonal, en la plenitud personal y en el apoyo social/emocional. Las acciones de protección social para familias vulnerables presentan poca cobertura e inciden en la presencia de bienestar interpersonal.

Introduction:

Opioids remain the most prescribed medication after total hip arthroplasty (THA) despite the potential for abuse and adverse effects. Given the high rates of opioid abuse and potential adverse effects, the reporting of controlled substances is now mandatory in many statewide databases. This study aimed to use a mandatory statewide database to analyze opioid prescription patterns in postoperative THA patients and identify independent risk factors for those patients who need a second prescription and/or require prolonged use (>6 months).

Methods:

We retrospectively reviewed a consecutive series of 619 primary THAs. Demographic and comorbidity information were collected for all patients. Narcotic prescription data (converted to morphine milligram equivalents) as well as prescription data for sedatives, benzodiazepines, and stimulants were collected from the State's Controlled Substance Monitoring websites 6 months before and 9 months after the index procedure. Bivariate and multivariate analyses were done for second prescription and continued use.

Results:

Of the 619 patients who underwent THA, 34.9% (216/619) used preoperative opioids, 36.2% (224/619) filled a second opioid prescription, and 10.5% (65/619) had continued use past 6 months. Patients with preoperative opioids were at an approximately 4-fold increased odds of requiring a second script and 12 times odds of continued opioid use. In the multivariate analysis, independent risk factors for requiring a second prescription, in descending order of magnitude, included the use of any sedative or sleep aid prescription and preoperative narcotic use. Independent risk factors for continued narcotic use longer than 6 months after THA included preoperative narcotic use and increased length of stay.

Discussion:

Several risk factors and their relative weight have been identified for continued narcotic consumption after THA. It is important for surgeons to consider these predisposing factors preoperatively during the informed consent process and for managing postoperative pain expectations.

Authors: Gayatri Maria
Published: February 2020

Long-acting reversible contraceptives (LARCs), consist of IUD and implats, were effective and efficient methods in preventing the pregnancy. However, the used of these methods in Indonesia was still low. This study sought to explore LARC utilization trends and the factors influencing LARC used among reproductive women in Indonesia. This research analyzed data from the Indonesia Demographic and Health Survey 2017. Respondents in this study were women who currently used modern contraceptive methods. A total of 20,409 women who used modern methods were included in the analysis. Descriptive analysis was performed using chi-square and percentages. Logistic regression with complex sample design was used to determine the associated factors in LARC utilization. Among women in reproductive age who currently used modern contraception, IUDs and implants were viewed particularly unfavorably which only 16.5% of women used LARC. Findings highlighted that higher LARC use among reproductive age women in Indonesia correlated with higher parity, older women, higher education, working women, desire to limit the pregnancy in the future and more visited by fieldworkers in the last 12 months. This study underscored that even though only 4% of respondents were visited by fieldworkers, the utilize of LARC was higher among women who visited by fieldworkers. This study suggests that communication skills among fieldworker need to be enhanced to do counselling and work closely with the community member.

The purpose of this paper is to explore the effective factors in attracting outbound tourists to choose Iran as a traveling destination. This survey has been done in China. The total number of respondents was 406, where 95% of respondents filled an online questionnaire and 5% filled it manually. The exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) were used to analyze the questionnaire, and logistic regression was deployed to explore the effective factors in this survey. The questions were defined based on the theory of planned behavior (TPB) and the role of culture, custom, the source of traveling information, and perceived traveling risks in choosing Iran as a traveling destination. The outcome of this survey on Chinese people suggested that the attractions of Iran, environment, and political risks are the main factors which play an important role in choosing Iran as a traveling destination. The experience of traveling abroad also revealed a significant effect in decision making on traveling destination.
Lo que no dicen los estudios sobre las transiciones formativas-laborales de los jóvenes
Authors: Moreno Almudena
Published: February 2020

En la última década se han multiplicado los estudios sobre las transiciones formativo-laborales como consecuencia de las cicatrices generadas por el desempleo y la precariedad entre los jóvenes durante la crisis económica. Por lo general se ha adoptado un enfoque reduccionista para estudiar las transiciones centrado en analizarlas como un proceso lineal y homogéneo extensible a todos los jóvenes, como un lugar común. Esto se debe a que las fuentes de datos disponibles no nos permiten profundizar y llegar a otros lugares donde quizás estén transitando esos jóvenes. La propuesta que aquí se presenta parte del diagnóstico descriptivo sobre el estado de la transiciones formativo-laborales en España para reflexionar a continuación sobre las limitaciones que tienen estos estudios y la necesidad de desarrollar nuevas herramientas analíticas y explorar nuevas fuentes de datos que nos permitan llegar a todas las transiciones formativas-laborales que están realizando los jóvenes. Esto nos permitirá hacer un mejor diagnóstico de la situación actual en la que se encuentran los jóvenes en sus diferentes biografías personales, familiares y culturales como base para proponer políticas de empleo y formativas eficaces que pueden afrontar el reto de un mercado laboral cada vez más complejo capaz de integrar a todos los jóvenes sin exclusión.
