Comparative studies on mobile forensic evidence extraction open source software for android phone

The Android Forensic software grows in numbers, and increased awareness of the data they process have also grown day to day basis, but much of the interest from cybercriminal to successfully attack the device and also the careless of the human being itself have placed the android phone content at the risk. Forensic examiner have always gone for an expensive forensic toolkit to meet the industry standards, but normal people have been always tent to lose the direction when they experience this type of attack or the data lost as it may cost a few thousand to fix it back. Therefore, the purpose of this paper is suggesting a reliable open source mobile forensic tool based on experiments conducted to retrieve deleted data and also extract other important content from android mobile phone

Predictors of Tuberculosis Treatment Outcome in an Urban Setting: A Retrospective Cohort Study

Abstract This is a retrospective cohort study on tuberculosis in 286 patients aged between 18-60 years who had completed anti-tuberculosis treatment for a minimum of six months for patients diagnosed with pulmonary tuberculosis and nine months for patients diagnosed with extra-pulmonary tuberculosis in an out-patient government clinic in Johor Bahru. Patients were analysed by age group, gender, ethnicity, occupation, types of tuberculosis, smear results, presenting chest X-Ray, presenting clinical symptoms, duration of symptoms, comorbidities and relevant social history. Treatment outcomes of patients were assessed based on clinical symptoms resolution, chest x-ray resolution and smear clearance at two months, four months and six months after commencement of treatment. The data was analyzed using SPSS version 16.0. Male gender, weight loss, night sweats, moderate to severe chest XRay findings, involvement of both lungs, smear positivity and smoking history were significant predictors of poor anti-tuberculosis treatment outcomes. On the other hand, smear negativity is a significant predictor of good treatment outcomes. Males, middle aged groups, ethnicity, lower social status and homemakers were at a higher risk of developing tuberculosis and thus further studies on these population groups are required.

Estimulação elétrica nervosa transcutânea após cirurgia de revascularização miocárdica Transcutaneous electrical nerve stimulation after coronary artery bypass graft surgery

INTRODUÇÃO: Após a cirurgia cardíaca, os pacientes apresentam limitação na força muscular respiratória, o que favorece a instalação de complicações pulmonares. OBJETIVO: Analisar a eficácia da estimulação elétrica nervosa transcutânea sobre o processo doloroso e força muscular respiratória em pacientes submetidos à cirurgia de revascularização do miocárdio (CRM). MÉTODOS: Foram inclusos pacientes em pós-operatório de CRM por meio de esternotomia, com uso de circulação extracorpórea, anestesia geral, sem estar sob efeito de bloqueio neuromuscular, uso de drenos de tórax e mediastino, extubados até 6 horas pós-procedimento e apresentando índice igual ou superior a três na escala analógica visual da dor (EVA), estando no primeiro dia de pós-operatório (1º DPO). Foram recrutados 20 pacientes, divididos em dois grupos, sem predomínio de sexo: Grupo Controle (n=10), que recebeu terapia analgésica mais fisioterapia; e Grupo TENS, que recebeu terapia analgésica, fisioterapia e TENS. A TENS foi aplicada por 30 minutos, três vezes ao dia, num intervalo de 3 horas cada aplicação. RESULTADOS: Para o grau de dor, houve uma média inicial e final, respectivamente, de 7,0 e 1,0 para o Grupo TENS e 7,0 e 8,0 para o Grupo Controle. Para a Pimáx, a média inicial e final foi de, respectivamente, -102,5 cmH2O e -141,17 cmH2O para o Grupo TENS e -97,0 cmH2O e -100,3 cmH2O para o Controle. Quanto a Pemáx, a média inicial e final foi de, respectivamente, 63 cmH2O e 125 cmH2O para o Grupo TENS e 55,3 cmH2O e 53,2 cmH2O para o Grupo Controle. CONCLUSÃO: A TENS demonstrou eficácia significativa na redução da algia e no aumento das forças musculares respiratórias no 1º DPO de CRM.<br>INTRODUCTION: After cardiac surgery, patients have a limitation in respiratory muscle strength, which favors the appearing of pulmonary complications. OBJECTIVE: To evaluate the effectiveness of transcutaneous electrical nerve stimulation (TENS) on the painful process and respiratory muscle strength in patients undergoing coronary artery bypass graft (CABG). METHODS: The study included patients after on-pump CABG through sternotomy, general anesthesia, without being under the influence of neuromuscular blockade, with use of chest and mediastinal tubes, and extubation within 6 hours after the procedure and presenting index equal to or greater than three visual analog scale (VAS) of pain being on the first day after surgery. We recruited 20 patients divided into two groups with no predominance of sex: the control group (n = 10), who received more physiotherapy analgesic therapy, and TENS group received analgesic therapy, physiotherapy and TENS. The TENS was applied for 30 minutes, three times a day, a 3-hour period each application. RESULTS: For the degree of pain, there was an average start and end, respectively, 7.0 / 1.0 for the TENS group and 7.0 / 8.0 for the control group. For inspiratory muscle strength, - 102.5 cmH2O / - 141.17 cm H2O to the TENS group and - 97.0 cmH2O / - 100.3 cm H2O for control. The expiratory muscle strength, 63cmH2O/125 cmH2O for the TENS group and 55.3 cmH2O/53, 2 cmH2O for the control group. CONCLUSIONS: TENS has shown significant effectiveness in reducing pain, and the increase in respiratory muscle strength at first-day after CABG surgery
