RESUMEN

PURPOSE OF REVIEW: Benzodiazepines, due to their anxiolytic properties, are prescribed to reduce anxiety and insomnia. They might have hypotensive effect via potentiation of the inhibitory effect of gamma-amino butyric acid (GABA) in the central nervous system and vasodilatory properties. However, studies comparing the effect of benzodiazepines in lowering blood pressure (BP) are equivocal. This systematic review and meta-analysis was planned to assess the efficacy of benzodiazepines in reducing blood pressure in short term among hypertensive patients. RECENT FINDINGS: Various trials and retrospective analysis conducted previously have reported that benzodiazepines cause short- as well as long-term BP reduction in patients with increased anxiety with hypertension. On the other hand, several studies investigating the efficacy of benzodiazepines in patients with hypertension have reported inconclusive results. The primary question about the effect of benzodiazepines in lowering BP remains unanswered. In this meta-analysis of seven studies, benzodiazepines were found comparable to standard drugs in reducing systolic and diastolic BP in patients having hypertension. Although, the mean difference in systolic BP with benzodiazepines and placebo was statistically not significant, the difference can be considered as clinically meaningful. The current review offers preliminary evidence that benzodiazepines may have antihypertensive properties and may be used as add-on antihypertensive in a subset of patients in short term. The existing data are encouraging, but more clinical trials and mechanistic research are required to ascertain the long-term benefits.

RESUMEN

Two convolution neural network (CNN) models are introduced to accurately classify event-related potentials (ERPs) by fusing frequency, time, and spatial domain information acquired from the continuous wavelet transform (CWT) of the ERPs recorded from multiple spatially distributed channels. The multidomain models fuse the multichannel Z-scalograms and the V-scalograms, which are generated from the standard CWT scalogram by zeroing-out and by discarding the inaccurate artifact coefficients that are outside the cone of influence (COI), respectively. In the first multidomain model, the input to the CNN is generated by fusing the Z-scalograms of the multichannel ERPs into a frequency-time-spatial cuboid. The input to the CNN in the second multidomain model is formed by fusing the frequency-time vectors of the V-scalograms of the multichannel ERPs into a frequency-time-spatial matrix. Experiments are designed to demonstrate (a) customized classification of ERPs, where the multidomain models are trained and tested with the ERPs of individual subjects for brain-computer interface (BCI)-type applications, and (b) group-based ERP classification, where the models are trained on the ERPs from a group of subjects and tested on single subjects not included in the training set for applications such as brain disorder classification. Results show that both multidomain models yield high classification accuracies for single trials and small-average ERPs with a small subset of top-ranked channels, and the multidomain fusion models consistently outperform the best unichannel classifiers.

RESUMEN

Background: Anterior Cruciate Ligament (ACL) injuries are common in the active population of the Armed Forces. Symptomatic instability prompts individuals to seek a cure or a sheltered appointment. Despite the increasing numbers of ACL reconstructions performed, the outcomes have not been so spectacular with only a meager percentage of our patients returning to preinjury levels of activity. With the premise that an all-inside ACL reconstruction is likely to result in better functional outcomes, the aim of this study was to compare the short-term functional outcomes of a large consecutive series of patients undergoing ACL reconstruction using the translateral all-inside ACL reconstruction technique (AI) and standard anteromedial portal technique (AM) with a minimum follow-up of one year. Methods: A total of 240 patients with isolated ACL tear underwent ACL reconstruction via the AI or AM technique. Their preoperative and postoperative scores were compared to look for any significant differences in functional outcomes. Results: The two groups were matched for age, BMI, mechanism of injury, and interval from injury to surgery. There was no difference in their preoperative scores. Postoperatively, although there were significant improvements across both groups, there was no significant difference between the groups at any point of time. Conclusion: The AI technique has garnered interest in recent literature in addressing ACL injuries. This study found no discernible benefit of the AI technique when compared to the AM technique in terms of functionality following an ACL reconstruction at any point of time up to 1 year following surgery.

RESUMEN

BACKGROUND: Acute seizure activity might cause complications including bodily harm, progression to status epilepticus, and poor quality of life in children. The introduction of a venous line may be difficult in children with seizures which would delay the initiation of treatment. Rectal drug administration can be socially awkward for patients and providers. Intranasal (IN) midazolam offers a valuable substitute that is easier and faster to administer. OBJECTIVE: To assess the efficacy, safety, and acceptability of intranasal midazolam in children with acute seizure when compared to conventional IV or rectal benzodiazepine (BDZ). METHODS: PubMed, google scholar, websites clinicaltrials.gov and the WHO-international clinical trials registry platform, were searched. Randomized controlled/prospective randomized trials comparing IN midazolam against IV/rectal BDZ in the treatment of acute seizures in pediatric patients were included in the meta-analysis. RESULTS: Data of 10 studies were quantitatively analyzed. Intranasal midazolam (n = 169) when compared to IV/rectal BDZ (n = 161) has a shorter interval between hospital arrival and seizure cessation {(mean difference = -3.51; 95% CI [-6.84, -0.18]) P = 0.04}. Regarding time to seizure cessation after midazolam (n = 326) or BDZ (n = 322) administration, there is no significant difference between the two groups {(mean difference = -0.03; 95% CI [-1.30, 1.25]), P = 0.97} and both are equally effective for controlling acute seizures (odds ratio = 1.06; 95% CI [0.43, 2.63]; n = 737). CONCLUSION: In children with acute seizures, IN midazolam is equally effective in aborting seizure and decreases the total time from hospital arrival and cessation of seizures, eventually leading to faster cessation of seizure as compared to IV/rectal BDZ.

RESUMEN

It is often difficult to predict seizure recurrence in subjects who have suffered a first-ever epileptic seizure. In this study, the predictive value of physiological signals measured using Electroencephalography (EEG) and functional MRI (fMRI) is assessed. In particular those patients developing epilepsy (i.e. a second unprovoked seizure) that were initially evaluated as having a low risk of seizure recurrence are of interest. In total, 26 epilepsy patients, of which 8 were initially evaluated as having a low risk of seizure recurrence (i.e. converters), and 17 subjects with only a single seizure were included. All subjects underwent routine EEG as well as fMRI measurements. For diagnostic classification, features related to the temporal dynamics were determined for both the processed EEG and fMRI data. Subsequently, a logistic regression classifier was trained on epilepsy and first-seizure subjects. The trained model was tested using the clinically relevant converters group. The sensitivity, specificity, and AUC (mean ±â€¯SD) of the regression model including metrics from both modalities were 74 ±â€¯19%, 82 ±â€¯18%, and 0.75 ±â€¯0.12, respectively. Positive and negative predictive values (mean ±â€¯SD) of the regression model with both EEG and fMRI features are 84 ±â€¯14% and 78 ±â€¯12%. Moreover, this EEG/fMRI model showed significant improvements compared to the clinical diagnosis, whereas the models using metrics from either EEG or fMRI do not reach significance (p > 0.05). Temporal metrics computationally derived from EEG and fMRI time signals may clinically aid and synergistically improve the predictive value in a first-seizure sample.

RESUMEN

We introduce a set of input models for fusing information from ensembles of wearable sensors supporting human performance and telemedicine. Veracity is demonstrated in action classification related to sport, specifically strikes in boxing and taekwondo. Four input models, formulated to be compatible with a broad range of classifiers, are introduced and two diverse classifiers, dynamic time warping (DTW) and convolutional neural networks (CNNs) are implemented in conjunction with the input models. Seven classification models fusing information at the input-level, output-level, and a combination of both are formulated. Action classification for 18 boxing punches and 24 taekwondo kicks demonstrate our fusion classifiers outperform the best DTW and CNN uni-axial classifiers. Furthermore, although DTW is ostensibly an ideal choice for human movements experiencing non-linear variations, our results demonstrate deep learning fusion classifiers outperform DTW. This is a novel finding given that CNNs are normally designed for multi-dimensional data and do not specifically compensate for non-linear variations within signal classes. The generalized formulation enables subject-specific movement classification in a feature-blind fashion with trivial computational expense for trained CNNs. A commercial boxing system, 'Corner', has been produced for real-world mass-market use based on this investigation providing a basis for future telemedicine translation.

RESUMEN

Background: Periostin is an extracellular matrix protein, and its expression is upregulated in airway epithelial cells in patients with bronchial asthma. Periostin may be a key molecule linked to type 2 T-helper cell inflammation. Inhaled corticosteroids (ICS) may suppress periostin-induced asthmatic inflammation. This study estimated the serum periostin levels in patients with asthma and evaluated the effect of ICS on the levels of periostin, peak expiratory flow rate (PEFR), and quality of life (QOL). Methods: The study design was prospective, open label, and observational. Forty adults with mild-to-moderate bronchial asthma started on ICS and matched healthy controls were enrolled. The patients were evaluated for their serum periostin, PEFR, and QOL by using asthma QOL questionnaire scores at baseline and after 4 weeks. Results: The mean ± standard deviation (SD) serum periostin concentration in patients with asthma was 90.36 ± 19.81 ng/mL, which was significantly higher (p < 0.01) compared with healthy controls (31.88 ± 8.71 ng/mL). ICS treatment for 4 weeks reduced the mean ± SD serum periostin levels to 58.78 ± 14.53 ng/mL. The mean ± SD PEFR increased significantly, from 225.25 ± 60.79 L/min to 292.5 ± 59.18 L/min (p < 0.01), after 4 weeks. Similarly, the mean ± SD when using asthma QOL questionnaire scores significantly increased, from 40.7 ± 7.84 at baseline to 59.33 ± 11.0 on day 28 after ICS therapy (p < 0.01). Conclusion: The serum periostin level, a marker of allergic inflammation and remodeling, increased in bronchial asthma and was reduced with ICS therapy. ICS improved QOL scores and PEFR in patients with asthma.

RESUMEN

Networked operation of unmanned air vehicles (UAVs) demands fusion of information from disparate sources for accurate flight control. In this investigation, a novel sensor fusion architecture for detecting aircraft runway and horizons as well as enhancing the awareness of surrounding terrain is introduced based on fusion of enhanced vision system (EVS) and synthetic vision system (SVS) images. EVS and SVS image fusion has yet to be implemented in real-world situations due to signal misalignment. We address this through a registration step to align EVS and SVS images. Four fusion rules combining discrete wavelet transform (DWT) sub-bands are formulated, implemented, and evaluated. The resulting procedure is tested on real EVS-SVS image pairs and pairs containing simulated turbulence. Evaluations reveal that runways and horizons can be detected accurately even in poor visibility. Furthermore, it is demonstrated that different aspects of EVS and SVS images can be emphasized by using different DWT fusion rules. The procedure is autonomous throughout landing, irrespective of weather. The fusion architecture developed in this study holds promise for incorporation into manned heads-up displays (HUDs) and UAV remote displays to assist pilots landing aircraft in poor lighting and varying weather. The algorithm also provides a basis for rule selection in other signal fusion applications.

RESUMEN

High-flow nasal oxygen therapy warms and humidifies gases, allows better clearance of secretions, along with providing added benefits like preventing dehydration of airway surface, while decreasing atelectasis and thereby, offering comfort to the patient. While its effect on critically ill patients is still in its pioneering phase, there is lack of substantial evidence on the use of high-flow nasal cannula in cardiac patients with type I respiratory failure. We found it worthwhile to share our experience of its use in elderly and postpartum patients with moderate-to-severe pulmonary hypertension, with associated comorbidities and type I respiratory failure, with do-not-intubate or defer intubation status. In patients with pulmonary hypertension (PHT) and respiratory failure, endotracheal intubation followed by initiation of mechanical ventilation may have detrimental hemodynamic effects. Increase in lung volumes and decrease in functional residual capacity lead to increase in pulmonary hypertension and right ventricle afterload. If a patient has right heart failure, lung hyperinflation can fatally reduce cardiac output. High-flow nasal oxygen therapy may be of an advantage in these scenarios.

RESUMEN

BACKGROUND: Glioma grade along with patient's age and general health are used for treatment planning and prognosis. PURPOSE: To characterize and quantify the spontaneous blood oxygen level-dependent (BOLD) fluctuations in gliomas using measures based on T2*-weighted signal time-series and to distinguish between high- and low-grade gliomas. STUDY TYPE: Retrospective. SUBJECTS: Twenty-one patients with high-grade and 13 patients with low-grade gliomas confirmed on histology were investigated. FIELD STRENGTH/SEQUENCE: Dynamic T2*-weighted (multislice single-shot echo-planar-imaging) magnetic resonance imaging (MRI) was performed on a 3T system with an 8-element receive-only head coil to measure the BOLD fluctuations. In addition, a dynamic T1 -weighted (3D fast field echo) dynamic contrast-enhanced (DCE) perfusion scan was performed. ASSESSMENT: Three BOLD measures were determined: the temporal shift (TS), amplitude of low frequency fluctuations (ALFF), and regional homogeneity (ReHo). DCE perfusion-based cerebral blood volume (CBV) and time-to-peak (TTP) maps were concurrently evaluated for comparison. STATISTICAL TESTS: An analysis-of-variance test was first used. When the test appeared significant, post-hoc analysis was performed using analysis-of-covariance with age as covariate. Logistic regression and receiver-operator characteristic curve analysis were also performed. RESULTS: TS was significantly advanced in high-grade gliomas compared to the contralateral cortex (P = 0.01) and low-grade gliomas (P = 0.009). In high-grade gliomas, ALFF and CBV were significantly higher than the contralateral cortex (P = 0.041 and P = 0.008, respectively) and low-grade gliomas (P = 0.036 and P = 0.01, respectively). ReHo and TTP did not show significant differences between high- and low-grade gliomas (P = 0.46 and P = 0.42, respectively). The area-under-curve was above 0.7 only for the TS, ALFF, and CBV measures. DATA CONCLUSION: Advanced and amplified hemodynamic fluctuations manifest in high-grade gliomas, but not in low-grade gliomas, and can be assessed using BOLD measures. Preliminary results showed that quantification of spontaneous fluctuations has potential for hemodynamic characterization of gliomas and distinguishing between high- and low-grade gliomas.

RESUMEN

PURPOSE: To assess the wavelet entropy for the characterization of intrinsic aberrant temporal irregularities in the time series of resting-state blood-oxygen-level-dependent (BOLD) signal fluctuations. Further, to evaluate the temporal irregularities (disorder/order) on a voxel-by-voxel basis in the brains of children with Rolandic epilepsy. MATERIALS AND METHODS: The BOLD time series was decomposed using the discrete wavelet transform and the wavelet entropy was calculated. Using a model time series consisting of multiple harmonics and nonstationary components, the wavelet entropy was compared with Shannon and spectral (Fourier-based) entropy. As an application, the wavelet entropy in 22 children with Rolandic epilepsy was compared to 22 age-matched healthy controls. The images were obtained by performing resting-state functional magnetic resonance imaging (fMRI) using a 3T system, an 8-element receive-only head coil, and an echo planar imaging pulse sequence ( T2*-weighted). The wavelet entropy was also compared to spectral entropy, regional homogeneity, and Shannon entropy. RESULTS: Wavelet entropy was found to identify the nonstationary components of the model time series. In Rolandic epilepsy patients, a significantly elevated wavelet entropy was observed relative to controls for the whole cerebrum (P = 0.03). Spectral entropy (P = 0.41), regional homogeneity (P = 0.52), and Shannon entropy (P = 0.32) did not reveal significant differences. CONCLUSION: The wavelet entropy measure appeared more sensitive to detect abnormalities in cerebral fluctuations represented by nonstationary effects in the BOLD time series than more conventional measures. This effect was observed in the model time series as well as in Rolandic epilepsy. These observations suggest that the brains of children with Rolandic epilepsy exhibit stronger nonstationary temporal signal fluctuations than controls. LEVEL OF EVIDENCE: 2 Technical Efficacy: Stage 3 J. Magn. Reson. Imaging 2017;46:1728-1737.

RESUMEN

OBJECTIVE: The diagnosis of epilepsy cannot be reliably made prior to a patient's second seizure in most cases. Therefore, adequate diagnostic tools are needed to differentiate subjects with a first seizure from those with a seizure preceding the onset of epilepsy. The objective was to explore spontaneous blood oxygen level-dependent (BOLD) fluctuations in subjects with a first-ever seizure and patients with new-onset epilepsy (NOE), and to find characteristic biomarkers for seizure recurrence after the first seizure. METHODS: We examined 17 first-seizure subjects, 19 patients with new-onset epilepsy (NOE), and 18 healthy controls. All subjects underwent clinical investigation and received electroencephalography and resting-state functional magnetic resonance imaging (MRI). The BOLD time series were analyzed in terms of regional homogeneity (ReHo) and fractional amplitude of low-frequency fluctuations (fALFFs). RESULTS: We found significantly stronger amplitudes (higher fALFFs) in patients with NOE relative to first-seizure subjects and healthy controls. The frequency range of 73-198 mHz (slow-3 subband) appeared most useful for discriminating patients with NOE from first-seizure subjects. The ReHo measure did not show any significant differences. SIGNIFICANCE: The fALFF appears to be a noninvasive measure that characterizes spontaneous BOLD fluctuations and shows stronger amplitudes in the slow-3 subband of patients with NOE relative first-seizure subjects and healthy controls. A larger study population with follow-up is required to determine whether fALFF holds promise as a potential biomarker for identifying subjects at increased risk to develop epilepsy.

RESUMEN

BACKGROUND: CD28 is a 44 kDa glycoprotein that is important in initiating T-cell responses and that results in increased T-cell proliferation and interleukin-2 production. This study estimated the serum CD28 levels in patients with asthma and evaluated the effect of inhaled corticosteroids (ICS) on the levels of CD28, the peak expiratory flow rate (PEFR), and quality of life (QOL). METHODS: This prospective, open-label, observational study enrolled 40 adult patients with asthma of mild-to-moderate severity who were started on ICS and 40 healthy controls. Patients with bronchial asthma were evaluated for their serum CD28 level and QOL by using Mini Asthma Quality of Life Questionnaire scores, severity of symptoms, and PEFR at baseline and after 4 weeks. RESULTS: The mean (standard deviation [SD]) serum CD28 concentration in patients with asthma was 107 ± 4.98 ng/mL, which was significantly elevated (p < 0.01) compared with the healthy individuals (37.67 ± 18.28 ng/mL). ICS treatment for 4 weeks reduced the mean (SD) serum CD28 levels to 40.9 ± 2.82 ng/mL. PEFR increased significantly, from 190.75 ± 10.55 to 263 ± 10.69 L/min (p < 0.01) after 4 weeks. Similarly, the mean (SD) Mini Asthma Quality of Life Questionnaire scores significantly increased, from 36.90 ± 10.31 on day 0 to 70.63 ± 11.56 on day 28 after ICS therapy (p < 0.01). A negative correlation between the elevations of serum CD28 levels was seen with QOL. CONCLUSION: The serum CD28 concentration, a marker of inflammation, is increased in bronchial asthma and reduced by ICS therapy. ICS also improved QOL scores and objective clinical outcomes in patients with asthma.

RESUMEN

OBJECTIVE: Good biomarkers are important to guide decisions in the clinical management of rheumatoid arthritis (RA). RA patients harbor antibodies directed against carbamylated proteins which may predict joint damage. This study investigated whether antibodies against carbamylated proteins (anti-CarP) may serve as surrogate prognostic markers. MATERIAL AND METHODS: Fifty-three patients with a diagnosis of rheumatoid arthritis according to ACR 1987 criteria were included. Blood samples were analyzed for CarP antibody levels using the ELISA method. Quality of life (QoL) was assessed by the WHO SF-36 questionnaire, and disease activity was assessed using the DAS28 calculator. Newly diagnosed patients were assessed at the first visit and at 12 weeks of treatment, while a single assessment was made for patients already on maintenance therapy. RESULTS: Out of 53 patients, 22 had titers of anti-CarP above the cut-off range and considered as positive for anti-CarP antibodies. Anti-CarP antibody serum level was significantly higher in patients with deformity of joints and with erosions in comparison to those without any destructive changes (p < 0.05). There was a weak positive correlation between anti-CarP and DAS 28 (p > 0.05). Also there was a weak negative correlation in all domains of quality of life with anti-CarP antibody titers (p > 0.05). There was no significant correlation between titers of anti-CarP antibodies and presence or absence of rheumatoid factor. CONCLUSIONS: Serum levels of anti-CarP antibodies in RA patients with joint erosions/deformities were much higher than in those without any joint damage. Anti-CarP antibodies may have good prognostic value in RA patients with erosions. Disease activity and QoL of RA patients improved during treatment, but no correlation was found between DAS 28/QoL and anti-CarP antibody serum levels.

RESUMEN

BACKGROUND: This study evaluated the clinical efficacy of mirtazapine and its effect on serum brain-derived neurotrophic factor (BDNF) and tumor necrosis factor-α (TNF-α) levels in patients of major-depressive disorder (MDD) with severe depression. METHODS: Patients (aged 18-60) with MDD diagnosed by DSM-IV criteria, and Hamilton Rating Scale for Depression (HAM-D) score ≥25 were included (n = 30). Mirtazapine was given in the doses of 30 mg/day. All patients were followed up for 12 weeks for the evaluation of clinical efficacy, safety along with serum BDNF and TNF-α levels. RESULTS: HAM-D score at the start of treatment was 30.1 ± 1.92, which significantly (p < 0.05) reduced to 13.47 ± 1.77 at 12 weeks of treatment. In responders, mean serum BDNF levels at the start of treatment were 2.32 ± 0.3 ng/ml, which significantly (p < 0.05) increased to 2.79 ± 0.33 ng/ml at 12 weeks of treatment and mean serum TNF-α levels at the start were 5.18 ± 0.67 pg/ml, which significantly decreased to 4.36 ± 0.72 pg/ml (p < 0.05) at 12 weeks of treatment. CONCLUSION: Our results suggest that mirtazapine is effective and well tolerated in severely depressed patients and treatment response is associated with an increase in serum BDNF and a decrease in serum TNF-α levels.

RESUMEN

An open label randomized controlled study was conducted to compare the quality of life (QoL) and safety of newly diagnosed stage I hypertensive patients randomized into two groups of 30 receiving either enalapril 5 mg or losartan 50 mg per-oral once daily for three months. QoL was assessed at the baseline and at the end of study using SF-36v2 health care questionnaire. Adverse drug reactions (ADRs) were monitored. Investigations at baseline were compared with those after intervention. Pre & post-intervention QoL transformed scores within each group and change in the same between two groups were analyzed using paired and unpaired t-test respectively. Transformed scores of role limitation due to energy/fatigue, emotional well being and general health domains improved significantly in both treatment groups. Scores of bodily pain improved significantly (p=0.0008) in losartan group only. Results were not significantly different between two groups (except for bodily pain). No serious ADR was reported.

RESUMEN

BACKGROUND: Acne scarring is a common sequela of acne for which no single treatment method is uniformly effective. The chemical reconstruction of skin scars (CROSS) therapy using high-concentration trichloroacetic acid (TCA) has shown promise as a cheap, safe, and effective modality of treatment in acne scars. OBJECTIVE: To assess the therapeutic response of 70% TCA CROSS on atrophic acne scars and to evaluate the adverse effects of this therapy. MATERIALS AND METHODS: Fifty-three patients with postacne atrophic scars were treated with 70% of TCA focal application every 2 weeks by the CROSS technique and results evaluated on 3 parameters: physician assessment, patient assessment, and satisfaction level of patients, after a follow-up of 3 months. RESULTS: Good or excellent improvement (>50%) was seen in 66% of patients on physician and patient assessments. The patients were either very satisfied or satisfied in 81.1% of cases. Patients with predominantly boxcar scars and higher pretreatment scar severity were associated with better treatment outcomes. Age, sex, duration of scars, or type of skin did not significantly influence the treatment outcome and adverse effects. CONCLUSION: The study showed that 70% of TCA is a safe and effective treatment option in all types of atrophic acne scars, especially in severe boxcar scars.

RESUMEN

Despite corticosteroids being the first line drug treatment for asthma symptom control, the mechanisms of action of corticosteroids in asthma are still poorly understood. The current study aimed to evaluate the effect of systemic corticosteroids on serum level of apoptotic markers Survivin (for inflammatory cells) and M30 apoptosense (for bronchial epithelial cells) in patients of acute exacerbation of bronchial asthma. The study involved 60 patients with acute exacerbation of bronchial asthma who were prescribed systemic corticosteroids. Patients were evaluated for their serum levels of apoptotic markers (Survivin and M30 apoptosense) and their quality of life (QOL), before and after treatment with oral prednisolone. Paired t-test was used to compare the change in the serum values. The mean baseline serum Survivin and M30 apoptosense levels were 224.10 ± 42.76 and 123.00 ± 18.79 U/L, respectively, which decreased significantly (p < 0.05) to 111.20 ± 32.26 and 29.67 ± 7.53 U/L after seven days of oral prednisolone treatment. Systemic corticosteroids also significantly improved QOL scores and peak expiratory flow rate % (PEFR%) in the asthma patients. This improvement was seen irrespective of the initial severity score. Results from the study suggest that systemic corticosteroids administration decreases the survival of inflammatory cells and increases that of bronchial epithelial cells in patients with acute exacerbation of bronchial asthma. The study has been registered with Clinical Trials Registry-India. Registry database number CTRI/2014/08/00483.
