Effect of home based pulmonary rehabilitation on health related quality of life in COPD patients

Background: Pulmonary rehabilitation is a proven strategy in the management of COPD, it’s a neglected area in our part of world and there are very few studies on home based pulmonary rehabilitation in COPD in our scenario and hence we evaluated the effectiveness of such a strategy. Aim of the research work was to study the effectiveness of home based pulmonary rehabilitation on health related quality of life, exercise tolerance, depression levels and perceived dyspnea as assessed by SGRQ (St. George Respiratory Questionnaire), 6MWTD (Six-Minute Walk Test distance), PHQ-9 (Patient Health Questionnaire-9), Modified Borg scale respectively.Methods: Patients attending the Department of Pulmonary Medicine, Medical College Trivandrum, diagnosed as COPD based on GOLD guidelines who fulfil the inclusion and exclusion criteria were studied from January 2013 to June 2014. Patients were educated about the disease and need for rehabilitation, advised smoking cessation, nutritional modification. Breathing exercise, upper limb and lower limb exercises given for 6 weeks in a structured manner and followed up in every second week and analyzed using paired t- test. Pre and post rehabilitation assessment included the SGRQ, 6MWTD, PHQ-9, Modified Borg dyspnea scale was done.Results: Around 40 patients had completed 6weeks of rehabilitation. There was a statistically and clinically significant improvement in quality of life, exercise tolerance, perceived dyspnoea was seen along with decrease in level of depression.Conclusions: Home based pulmonary rehabilitation is a feasible alternative to institution based rehabilitation in the management of COPD and is associated with significant benefit

Application of artificial neural networks for prokaryotic transcription terminator prediction

Artificial neural networks (ANN) to predict terminator sequences, based on a feed-forward architecture and trained using the error back propagation technique, have been developed. The network uses two different methods for coding nucleotide sequences. In one the nucleotide bases are coded in binary while the other uses the electron-ion interaction potential values (EIIP) of the nucleotide bases. The latter strategy is new, property based and substantially reduces the network size. The prediction capacity of the artificial neural network using both coding strategies is more than 95%

Experiences of survivors of commercial sexual exploitation availing rehabilitation at R&P homes in India

Background: Sex trafficking constitute as the primary form of human trafficking involving predominantly young girls and women. Rehabilitation of rescued victims of commercial sexual exploitation is critical in efficient reintegration into society. Aims: The main aim of the study is to explore the narratives of the victims of commercial sexual exploitation in understanding various factors towards eventual Rehabilitation within Rehabilitation & Protection (R&P) homes in India. Method: The study involves participatory action research at R&P homes in India. In total, 30 victims of commercial sexual exploitation, aged 29-50 years, participated in the study. Results:  The result through thematic analysis reflected the initiators and detrimental factors towards Rehabilitation in R&P homes. The analysis also reflected various internal and external factors contributing to effective Rehabilitation. Conclusion: The results provide insight into various factors for critical action by practitioners on the field through intervention, policies, and other mechanisms. The research also emphasizes the employment of participatory action research for research with the critical and marginalized population

Utilization of bedside ultrasound in the diagnosis and management of massive pulmonary embolism: a case report

AbstractThe prompt diagnosis and treatment of massive pulmonary embolism is a well-known challenge for physicians. We report a case of a 61-year-old hemodynamically unstable man who presented to the emergency department with complaints of acute dyspnea. After performing a focused history and physical, we used bedside ultrasound to diagnose significant right heart strain, which suggested massive bilateral pulmonary embolisms. This diagnosis was further supported by the visualization of deep venous thrombosis in the left lower extremity. The patient was treated with IV tissue plasminogen activator in the emergency department and survived to discharge in his usual state of health

Identification of CD4-Binding Site Dependent Plasma Neutralizing Antibodies in an HIV-1 Infected Indian Individual

Dissecting antibody specificities in the plasma of HIV-1 infected individuals that develop broadly neutralizing antibodies (bNAbs) is likely to provide useful information for refining target epitopes for vaccine design. Several studies have reported CD4-binding site (CD4bs) antibodies as neutralization determinants in the plasma of subtype B-infected individuals; however there is little information on the prevalence of CD4bs specificities in HIV-infected individuals in India. Here, we report on the presence of CD4bs antibodies and their contribution to virus neutralization in the plasma from a cohort of HIV-1 infected Indian individuals. Plasma from 11 of the 140 HIV-1 infected individuals (7.9%) studied here exhibited cross-neutralization activity against a panel of subtype B and C viruses. Analyses of these 11 plasma samples for the presence of CD4bs antibodies using two CD4bs-selective probes (antigenically resurfaced HXB2gp120 core protein RSC3 and hyperglycosylated JRFLgp120 mutant ΔN2mCHO) revealed that five (AIIMS 617, 619, 627, 642, 660) contained RSC3-reactive plasma antibodies and only one (AIIMS 660) contained ΔN2mCHO-reactive antibodies. Plasma antibody depletion and competition experiments confirmed that the neutralizing activity in the AIIMS 660 plasma was dependent on CD4bs antibodies. To the best of our knowledge, this is the first study to report specifically on the presence of CD4bs antibodies in the plasma of a cohort of HIV-1 infected Indian donors. The identification of CD4bs dependent neutralizing antibodies in an HIV-1 infected Indian donor is a salient finding of this study and is supportive of ongoing efforts to induce similar antibodies by immunization

Effects of bidi smoking on all-cause mortality and cardiorespiratory outcomes in men from south Asia: an observational community-based substudy of the Prospective Urban Rural Epidemiology Study (PURE)

Background: Bidis are minimally regulated, inexpensive, hand-rolled tobacco products smoked in south Asia. We examined the effects of bidi smoking on baseline respiratory impairment, and prospectively collected data for all-cause mortality and cardiorespiratory events in men from this region.Methods: This substudy of the international, community-based Prospective Urban Rural Epidemiology (PURE) study was done in seven centres in India, Pakistan, and Bangladesh. Men aged 35–70 years completed spirometry testing and standardised questionnaires at baseline and were followed up yearly. We used multilevel regression to compare cross-sectional baseline cardiorespiratory symptoms, spirometry measurements, and follow-up events (all-cause mortality, cardiovascular events, respiratory events) adjusted for socioeconomic status and baseline risk factors between non-smokers, light smokers of bidis or cigarettes (≤10 pack-years), heavy smokers of cigarettes only (\u3e10 pack-years), and heavy smokers of bidis (\u3e10 pack-years).Findings: 14 919 men from 158 communities were included in this substudy (8438 non-smokers, 3321 light smokers, 959 heavy cigarette smokers, and 2201 heavy bidi smokers). Mean duration of follow-up was 5·6 years (range 1–13). The adjusted prevalence of self-reported chronic wheeze, cough or sputum, dyspnoea, and chest pain at baseline increased across the categories of non-smokers, light smokers, heavy cigarette smokers, and heavy bidi smokers (p\u3c0·0001 for association). Adjusted cross-sectional age-related changes in forced expiratory volume in 1 s (FEV1) and FEV1/forced vital capacity (FVC) ratio were larger for heavy bidi smokers than for the other smoking categories. Hazard ratios (relative to non-smokers) showed increasing hazards for all-cause mortality (light smokers 1·28 [95% CI 1·02–1·62], heavy cigarette smokers 1·59 [1·13–2·24], heavy bidi smokers 1·56 [1·22–1·98]), cardiovascular events (1·45 [1·13–1·84], 1·47 [1·05–2·06], 1·55 [1·17–2·06], respectively) and respiratory events (1·30 [0·91–1·85], 1·21 [0·70–2·07], 1·73 [1·23–2·45], respectively) across the smoking categories.Interpretation: Bidi smoking is associated with severe baseline respiratory impairment, all-cause mortality, and cardiorespiratory outcomes. Stricter controls and regulation of bidis are needed to reduce the tobacco-related disease burden in south Asia

Bilateral Transplantation of Allogenic Adult Human Bone Marrow-Derived Mesenchymal Stem Cells into the Subventricular Zone of Parkinson's Disease: A Pilot Clinical Study

The progress of PD and its related disorders cannot be prevented with the medications available. In this study, we recruited 8 PD and 4 PD plus patients between 5 to 15 years after diagnosis. All patients received BM-MSCs bilaterally into the SVZ and were followed up for 12 months. PD patients after therapy reported a mean improvement of 17.92% during “on” and 31.21% during “off” period on the UPDRS scoring system. None of the patients increased their medication during the follow-up period. Subjectively, the patients reported clarity in speech, reduction in tremors, rigidity, and freezing attacks. The results correlated with the duration of the disease. Those patients transplanted in the early stages of the disease (less than 5 years) showed more improvement and no further disease progression than the later stages (11–15 years). However, the PD plus patients did not show any change in their clinical status after stem cell transplantation. This study demonstrates the safety of adult allogenic human BM-MSCs transplanted into the SVZ of the brain and its efficacy in early-stage PD patients
