Survey on Automated Bugs Triage System

Nowadays IT companies is spending more than 40 percent of their cost in fixing software bugs, traditonally these bugs are fixed by manual assignement to a particular developer , this approach causes too much dependency, the new and alternative approach is the bug triage system which fix the bug automatically , which automatically assign the reported bug to a develop which decreases the time and cost in in manual work, different classification techniques are used to conduct automatic bug triage. In this paper, we propose to apply machine learning techniques to assist in bug triage to predict which developer should be assigned on the bug based on its description by applying text categrorization . We will address the problem of data reduction for bug triage, i.e. How the quality of bug data would be improved

Unusual case of non-resolving necrotizing pneumonia: a last resort measure for cure.

Abstract To our knowledge, this is an unusual case of a community-acquired pneumonia (CAP) with sepsis secondary to Streptococcus pneumoniae that required lung resection for a non-resolving consolidation. A 74 year old previously healthy woman, presented with acute fever, chills and pleuritic chest pain in Emergency Department (ED). A diagnosis of CAP was established with a Pneumonia Severity Index CURB-65 score of 5/5. In the ER, she was promptly and appropriately managed with antibiotics and aggressive supportive therapy. She remained on ten days of intravenous antibiotics. However, 48 hours post antibiotic course, she returned to ER with fever and signs of sepsis. Despite timely and appropriate management, the consolidated lobe remained the focus of sepsis for over four weeks. The patient recovered after the offending lobe was resected. Histopathology of the lung tissue revealed acute and chronic inflammation. However, no malignancy, bacterial infection or broncho-pleural fistula was found. Eighteen months post-surgery, the patient remains well

Influence of Near Fault Earthquakes with Forward Directivity and Fling Step on Seismic Response of Steel Box-Girder Bridge

The existing bridge seismic design guidelines that rely on the ground acceleration in the far fault zone, ignore the potential impact of near fault forward directivity and fling-step effects on the bridge structures. In the current study probabilistic seismic damage evaluation of a continuous four-span box girder bridge under the impact of near-fault forward directivity and fling step effect is studied employing the fragility analysis. The incremental dynamic analysis is used to construct the fragility curves which shows a range of damage states from minor to collapse for the different damage metrics and for the considered peak ground acceleration varying between 0.1g and 1.2g. Damage metrics such displacement pier ductility, rotational pier ductility and displacement of girder are used to develop the fragility curves and the probabilistic seismic damage model. To evaluate the bridge vulnerability, a probabilistic seismic damage assessment is performed using an ensemble of forward directivity and an ensemble of fling-step comprising permanent ground offset. The suggested probability-based earthquake damage framework is anticipated to be a well-versed model able to estimate the seismic damages to the continuous box girder bridges while taking into account the variation of near fault earthquakes. The findings show that, even at low PGA values the forward directivity and the fling-step ground motions represent a significant risk to the bridge

STUDY ON PREVALENCE OF ADVERSE DRUG REACTIONS IN PATIENTS SUFFERING FROM TUBERCULOSIS IN A TERTIARY CARE HOSPITAL

Objective: To study the prevalence of ADRs associated with the use of anti-tubercular drugs in patients with tuberculosis in a tertiary care hospital.Methods: A prospective observational and active surveillance study was conducted in the department of pulmonology and DOTS Centre in Owaisi Hospital and Research Centre over a period of 6 mo after the study was approved by IRB. The patients who gave informed consent were included in the study and their information was analysed after being recorded in a data collection form.Results: Descriptive statistical analysis was carried out to generate results, the continuous measurement being presented as mean standard deviation (min-max) and categorical measurement presented in number (%). The results showed the prevalence of ADRs to be 69%. The prevalence of ADRs was more in females (55%) than in males (45%) and 75.9% of them reporting more than 1 ADR. ADR's affecting the skin and appendages were high (23.56%) while ADR's affecting gastrointestinal system (19.28%), the hepatic system (4.28%), the musculoskeletal system (15.7%), Central and peripheral nervous system (7.85%), Vision (0.7%) were comparatively less.Conclusion: The study highlighted the importance of developing strategies to ameliorate ADRs both to improve the quality of patient care and to control TB safely.Â

Infantile haemangioendothelioma of the parotid gland: Case report and review of literature

Haemangioendotheliomas (HAE), although rare but are the most common parotid gland tumours in children. We report a 4-month-old girl who presented with a progressively enlarging right sided facial swelling overlying the angle of the mandible. An Ultrasound of the lesion and a computed tomography (CT) scan of the head and neck was carried out which revealed a large lesion within the right parotid gland. CT scan further demonstrated a direct communication with the right external carotid artery and external jugular vein. Considering the clinical course and radiological findings, there was sufficient evidence to avoid any invasive testing. Due to the self-limiting nature of the disease, patient was managed expectantly

Development and validation of sunlight exposure measurement questionnaire (SEM-Q) for use in adult population residing in Pakistan

Background: Vitamin D deficiency has been identified as a major public health problem worldwide. Sunlight is the main source of vitamin D and its measurement using dosimeters is expensive and difficult for use in population-based studies. Hence, the aim of this study was to develop and validate questionnaires to assess sunlight exposure in healthy individuals residing in Karachi, Pakistan. Methods: Two questionnaires with seven important items for sunlight exposure assessment were developed. Fifty four healthy adults were enrolled based on their reported sunlight exposure (high = 17, moderate = 18, low = 19) from Aga Khan University, Karachi. Over four days, study participants were asked to wear a dosimeter between sunrise and sunset and report time spent and activities undertaken in the sun for questionnaire validation. Algorithm for item weightage was created as an average score based on ultraviolet B percentage received. Blood samples were obtained for serum vitamin D. Results: The mean time (minutes) spent in sun over 4 days (±SD) was 69.5 (±32) for low, 83.5 (±29.7) for moderate and 329 (±115) for high exposure group. The correlation between average time (minutes) spent in sun over 4 days and mean change in absorbance of UV dosimeters for 4 days was 0.60 (p \u3c 0.01). Correlation between average score and vitamin D levels was found to be 0.36 (p = 0.01) for short term questionnaire score, 0.43 (p = 0.01) for long term questionnaire score in summers and 0.48 (p = 0.01) in winters. Conclusions: The sunlight exposure measurement questionnaires were valid tools for use in large epidemiological studies to quantify sunlight exposure

Impact of Maternal Education about Complementary Feeding on Their Infants\u2019 Nutritional Outcomes in Low- and Middle-income Households: A Community-based Randomized Interventional Study in Karachi, Pakistan

This cluster-randomized interventional trial at peri-urban settings of Karachi was conducted to evaluate the impact of maternal educational messages regarding appropriate complementary feeding (CF) on the nutritional status of their infants after 30 weeks of educational interventions delivered by trained community health workers. Mothers in the intervention group received three education modules about breastfeeding (BF) and appropriate CF at a baseline visit and two subsequent visits 10 weeks apart. The control group received advice about BF according to national guidelines. Infants\u2019 growth [weight, length, and mid-upper arm-circumference (MUAC), stunting, wasting, and underweight] were measured at four time points. At the end of the study, infants in the intervention group had a higher mean weight of 350 g (p=0.001); length of 0.66 cm (p=0.001), and MUAC of 0.46 cm (p=0.002) compared to the controls; proportionate reduction of stunting and underweight were 10% (84% vs 74%; ORadj 8.36 (5.6-12.42) and 5% (25% vs 20%; ORadj 0.75 (0.4-1.79) in the intervention compared to the control group. For relatively food-secure populations, educational interventions about appropriate CF to mothers had a direct positive impact on linear growth of their infants

Assessment of hospital pharmacists' clinical knowledge and practical skill levels for pharmaceutical care in Madinah, Saudi Arabia

Purpose: To evaluate hospital pharmacists’ clinical knowledge and practical skill levels for pharmaceutical care.Methods: A quasi-experimental prospective longitudinal study design was used to evaluate the level of clinical skills with problem-based learning (PBL) sessions. Pharmacists’ in three different government hospitals in Madinah, Saudi Arabia recorded their responses or assessments in their work manuals for preparing reports. Instructors encouraged interactive learning by presenting case studies, in which pharmacists had to interpret medical history and clinical assessments of various body systems. Course learning design also focused on drug use evaluation, monitoring plans, and reaching clinical evidencebased decision-making.Results: A total of two hundred and fifty-five (255) hospital pharmacists participated in the study. The study sample was comprised of 128 (50.9 %) males and 127 (49.1 %) females. A significant (p < 0.01) difference was noticed between genders (male: 47.91 ± 7.15, female: 50.31 ± 4.88) for total mean scores of clinical skills. Cronbach’s alpha reliability coefficient for case data recitation was 0.91, while clinical assessment skills coefficient was 0.89. Overall, pharmacists reported that they “agree” (4.01 ± 0.67) that they acquired the ability to use case data recitation taught in the PBL; they also reported a positive evaluation (4.48 ± 0.58) of their ability to perform clinical data assessment.Conclusion: The findings indicate that pharmacist’s self-confidence to perform clinical assessment activities is low. Lack of confidence remains a critical education issue among pharmacists in the study setting.Keywords: Clinical pharmacy, Problem-based learning, Clinical skills, Pharmacist focus group, Therapeutics, Pharmaceutical car

Exploring the impact of gender inequities on the promotion of cardiovascular health of women in Pakistan

Cardiovascular disease exerts an enormous burden on women\u27s health. The intake of a healthy diet may reduce this burden. However, social norms and economic constraints are often factors that restrain women from paying attention to their diet. Underpinned by critical realism, this study explores how gender/sex influences decision-making regarding food consumption among women of low socioeconomic status (SES). The study was carried out at two cardiac facilities in Karachi, Pakistan, on 24 participants (male and female from different ethnic backgrounds), who had received health education. Using an interpretive descriptive approach, the study identified major barriers to a healthy diet: proscribed gender roles and lack of women\u27s autonomy, power, male domination, and abusive behaviours. Cardiovascular risk and disease outcomes for the Pakistani women of low SES are likely to further escalate if individual and structural barriers are not reduced using multifactorial approaches
