Pre Processing of Twitter's Data for Opinion Mining in Political Context

AbstractIn the wake of political activism among youth in particular and the whole population in general, everyone is not only eager to share their political orientation but equally curious regarding the voice of the masses. As a known notion, the perfect orifice to this emerging need of political activism can be found on social media platforms, from where the numerous aspects of public opinion can be captured easily. These sites have begun to have a large impact on how people think and act. It is a known phenomenon that public opinion is the largest indicator of success and failure of political parties and is a direct reflection of the party's reign. Where increased sharing of public feedback has increased awareness and promoted accountability, it has also created chaos and confusion for many. Using Twitter, the most popular micro blogging platform, this paper aims to give a method to ease and smooth the task of opinion mining with the help of linguistic analysis and opinion classifiers, which will together determine positive, negative and neutral sentiments for the political parties of Pakistan. A method is provided which pre-processes the raw data of twitter and comparison of two classification techniques to classify this data. That will aspire to capture a snapshot of current political scenario to promote the spirit of accountability, self-analysis and improvement in among Pakistani politicians. Moreover, with this we aim to give general public an important consolidated voice in the realm of politics

Establishing normal range of fetal renal artery RI and PI values in singleton pregnancies during 18-38 weeks of gestation

INTRODUCTION: Human kidney constitutes an integral organ during the period of embryogenesis. The use of regular ultrasound during antenatal follow ups not only assesses structural aspects of fetal body but can also evaluate functional integrity of developing organs to some extent. Unfortunately, fetal renal hemodynamics has been studied more in western population which have better socio-economic status as well as good antenatal care. Our study aims at establishing a normal reference range for fetal renal artery indices in healthy Pakistani pregnant population which has not been done before. METHODOLOGY: This is a nonprobability convenient study investigating 130 healthy pregnant women during 18-38weeks of gestation. Resistivity and pulsatility indices (RI and PI) of the fetal renal arteries were evaluated dividing the patients in four groups as per their gestational age. Normal reference ranges of RI and PI values were established. P values for RI and PI were also being calculated. RESULTS: Mean values of the RI and PI of the fetal renal arteries were calculated. P value for RI is 0.05 and PI is 0.69. Hence the values remain unaltered with advancing gestational age. CONCLUSIONS: These reference ranges demonstrate the minimal change of the fetal renal hemodynamics during healthy pregnancies pertinent to our reference population. These may be applicable in antenatal practice to identify deviations from these reference ranges and will be beneficial in further studies related to prediction of fetal renal function.  

A Case Report on Reverse Tokotsubo Cardiomyopathy: Diagnosis and Path toward Treatment

Reverse takotsubo cardiomyopathy (rTTC), also known as inverted takotsubo syndrome, is an acute cardiac syndrome that mimics myocardial infarction and accounts for a smaller proportion of cases compared to the classic takotsubo syndrome. While the exact prevalence is not well-established, studies suggest that the proportion of patients with the rTTC variant out of all Takotsubo Cardiomyopathy (TTC) according to different literature ranges from 1-23%. This variant of TTC is characterized by basal and/or mid-akinesis/hypokinesis associated with apical hyperkinesis that resolves spontaneously. We report a case of a 30-year-old male patient who presented with complaints of sudden crushing chest pain and shortness of breath. After conducting a thorough examination, the patient’s diagnostic workup confirmed reverse takotsubo cardiomyopathy, elucidating the underlying cardiac patholog
