Efficacy of a Structured Yoga Intervention Integrated with Routine Care versus Exercise on Pulmonary Function and Quality of Life of Asthma Patients: A Randomized Controlled Trial.

Context: Asthma is a chronic disease and its chronicity demands therapy with minimal harm and a good impact on the quality of life of asthmatics. Objective: This study evaluates the efficacy of structured yoga intervention integrated with routine care on asthma patients in improving their pulmonary function and quality of life. Design: The study was a single-blind (outcome assessor) hospital-based randomized controlled trial. Participants: Adults between 18 to 60 years, diagnosed with mild to moderate asthma as per Global Initiative for Asthma guidelines, with no exacerbation in the past month before screening, were included in the study. Intervention: A thirty-minute structured yoga intervention was delivered daily by a qualified yoga instructor through a virtual platform. Outcome measures: Questionnaires were utilized to assess the quality of life, and Breath-o-meter equipment was used to measure peak expiratory flow rate (PEFR). It was tested at baseline and then at 15 days, 45 days, and 90 days, whereas the quality of life was evaluated once a month. Statistical analysis: Intention to treat analysis was performed to compare the mean outcome between the yoga and control groups using an independent sample t test and repeated measures analysis of variance. Results: The yoga group significantly improved their PEFR and asthma-related quality of life scores compared to the control group (P < .001). A significant difference (F = 539.72, degree of freedom = 1.1618; P < .001) was detected between PEFR values at several time intervals (baseline, day 15, day 45, day 90) in the intervention group on repeated measures analysis of variance. The difference in quality-of-life scores between yoga and control was also statistically significant (P < .001), with an improvement in the quality-of-life domain of external stimuli. Conclusion: When combined with normal asthma treatment, the findings of this study show that structured yoga intervention integrated with routine care is more beneficial than traditional breathing exercises in increasing PEFR and quality of life.

Clinical, radiological and histopathological profile of patients with endobronchial lesions on fibreoptic bronchoscopy.

Various pulmonary diseases, both benign as well as malignant, manifest in the form of endobronchial lesions on bronchoscopy. Malignancy is frequently the provisional diagnosis in the mind of a chest physician undergoing an endobronchial biopsy. Other benign diseases, however, may present similarly on bronchoscopy and computerized tomography (CT) scan. This observational study was conducted to better understand why there is such a wide range of endobronchial lesions with even more diverse radiological and pathological presentations. The research was carried out at the Department of Respiratory Medicine, Himalayan Institute of Medical Science (HIMS), Swami Ram Nagar, Dehradun. Subjects were recruited from HIMS, Dehradun patients over a 12-month period (August 2020 to July 2021). The study included patients (over the age of 18) who had a fibreoptic bronchoscopy and were found to have an endobronchial lesion. After a thorough history, examination, and application of the inclusion and exclusion criteria, 120 patients were enrolled. The majority of patients were between the ages of 56 and 65, with males outnumbering females. The majority of the patients were smokers, and the most common complaint was shortness of breath. Poorly differentiated carcinoma and squamous cell carcinoma were the most common endobronchial lesions in men, while small cell carcinoma was the most common in women. A mass lesion was the most common radiological finding, followed by mediastinal lymphadenopathy, and an exophytic lesion was the most common endobronchial lesion detected in bronchoscopy. We looked at the diseases that cause endobronchial lesions and their clinico-radiological and histopathological profiles. This study clearly demonstrates the importance of studying the histopathological profiles of patients with endobronchial growth, which can mimic malignancy in rare cases.

Neutrophil-to-lymphocyte ratio in community-acquired pneumonia: Diagnostic potential and its limitations in the COVID era.

Objective: To determine the diagnostic potential of neutrophil-to-lymphocyte ratio (NLR) as a POC marker to discriminate tuberculous from non-tuberculous CAP and identify limitations if any at a tertiary care centre in Uttarakhand, India. Methods: 225 patients presenting with respiratory complaints were recruited from the General Medicine clinics and investigated. NLR was noted at onset and correlated with final diagnosis. Results: NLR from both groups did not exhibit a statistically significant difference. The area under curve (AUC) exhibited an accuracy of 49.1% in differentiating tuberculous from non-tubercular CAP, and an anomalous effect of prior steroid exposure on NLR was noted as a limitation. Conclusion: The disparity of our results from previous studies warranted a review of literature which rendered a significant limitation of NLR. The NLR is affected by catecholamines, which makes the marker unreliable in patients with exogenous steroid exposure. This was not noted in the previous studies. We presume indiscriminate steroid usage in the pandemic confounded our findings. We propose that this limitation be accounted for in future studies so that NLR's true utility may be identified.

Sarcoidosis associated with Trastuzumab in a young female with carcinoma of breast.

Trastuzumab is a humanized monoclonal antibody against human epidermal growth factor, useful in breast cancer. It is well tolerated but sometimes may associate with significant adverse effects. Sarcoidosis is a granulomatous disease involving multiple organs with poorly understood aetiology. Mediastinal lymphadenopathy is the most common presenting feature of Sarcoidosis. Reported cases of Sarcoidosis associated with Trastuzumab are quite less in number. High degree of suspicion of the above is thought of in a scenario of malignancy patients receiving chemotherapy. Newly appearing FDG avid lymph node in PET scan may give first impression of metastasis and treatment failure or infection. However correct diagnosis is a must (differentiating metastasis, treatment failure or infection) to provide correct treatment and avoid side effects of inappropriate therapies. Correct diagnosis also helps in appropriate prognostication and unnecessary stoppage of Trastuzumab. Here we are describing Sarcoidosis associated with Trastuzumab in a patient with breast cancer.

Multidrug-Resistant Musculoskeletal Tuberculosis: An Aggressive Clinical, Radiological and Molecular Confirmation With Genotypic Drug Susceptibility Testing Approach.

Introduction Increasing evidence suggests that musculoskeletal tuberculosis (MSTB) causes significant morbidity due to the late presentation of symptoms and lack of accurate diagnosis. We aimed to assess the utility of two modalities, viz. radiology and molecular methods, in the early diagnosis of MSTB. Also, the rate of resistance to two basic first-line antitubercular drugs in musculoskeletal TB cases among clinically suspected patients was analyzed. Methods Samples from 119 patients with clinical suspicion of musculoskeletal TB were included. A radiological workup of patient and smear microscopy, mycobacterial culture, real-time multiplex polymerase chain reaction (PCR), cartridge based nucleic acid amplification test (CBNAAT), and line probe assay (LPA) of samples were carried out. Results Maximum positivity (69.74%) was observed by real-time multiplex, followed by CBNAAT and LPA (68.9%), mycobacterial culture (40.3%), and smear microscopy (19.3%). One additional advantage of using multiplex PCR was the detection of non-tuberculous mycobacteria (NTM) isolate. Forty-five strains (54.9%) on LPA were susceptible to rifampicin and isoniazid, eight (9.8%) were rifampicin mono-resistant, seven (8.5%) were isoniazid (INH) mono-resistant, and 22 (26.8%) were multidrug resistant. Conclusions MSTB diagnosis can be expedited by the combination of radiology and molecular methods. The positivity rate escalates, turnaround time improves, and the additional advantage of detection of drug resistance is added when this algorithm is included for clinching the diagnosis of MSTB.

Clinical profile and in-hospital outcomes of COVID-19 patients: Findings from secondary data analysis.

Background: Uttarakhand, a hilly state in north India, reported the first coronavirus disease (COVID) case on 15 March 2020. Since then, the case numbers rose multiple folds. As Uttarakhand has been on a 'war-footing' amidst the recent second wave and is gearing up to fight against the third wave, the present study aims to uncover baseline clinical profile and in-hospital outcomes of COVID patients in Dehradun district (Uttarakhand) during the first wave. Methods: A record-based descriptive analysis was carried out for 671 COVID patients admitted to a private dedicated COVID hospital in Dehradun district between August 2020 and February 2021. Data was collected from medical records on a standardized abstraction form. Data was entered and analyzed using Statistical Package for Social Sciences (SPSS) version 20. Results: The present study showed most admitted COVID patients were males, aged 40 years and above, moderately ill, had co-morbidities with about one-fourth lately succumbed to death. The proportions of deaths, moderate-to-severe and severe category of illness were invariably high for those with co-morbidities irrespective of the gender. Females, age <60 years, and absence of co-morbidities had overall high mean survival estimates from COVID. Conclusion: Females, younger age group, and absence of co-morbidities are more likely to survive from COVID than males, older age groups, and those with co-morbidities.

Dry eye disease and retinal nerve fiber layer changes in chronic smokers.

Purpose: To study the effect of smoking on tear film parameters and retinal nerve fiber layer thickness (RNFL) in chronic smokers. Methods: This was a cross-sectional study, which included 60 (120 eyes) smokers who have smoked at least 10 pack-year and an equal number of healthy subjects as a control for comparison. In addition to history, a detailed slit-lamp examination was done to evaluate the anterior and posterior segments. All patients underwent Schirmer's I test (SIT) with Whatman-41 filter paper, tear meniscus height (TMH), and RNFL with a Fourier-domain optical coherence tomography (OCT) and tear film breakup time (TBUT) with 2% fluorescein and cobalt blue filter using slit-lamp biomicroscopy. Results: The (mean ± SD) age of the participants was 56.48 ± 10.38 years. There was a statistically significant reduction in tear film parameters in smokers compared to nonsmokers (P = 0.000). The incidence of MGD was found to be higher in smokers when compared to nonsmokers with a P value of 0.000. RNFL in all four quadrants was also significantly reduced in smokers compared to nonsmokers (P = 0.00). Conclusion: This study shows that chronic smoking leads to an increased incidence of dry eye disease and is associated with RNFL thinning. Smoking can result in cumulative RNFL loss in patients with ocular neurodegenerative disorder and OCT of these patients may have to be interpreted keeping this in mind.

Combating COVID-19 pandemic in India: Demystifying the concept of herd immunity.

The concept of Herd immunity is a key factor for epidemic control. According to it only a proportion of entire population needs to be immune either via natural infection or vaccination. The idea of herd immunity via natural infection rather than vaccination is a bit controversial, as it is not clear how long will the antibodies last, and whether re-infection or re-activation of the virus can occur after the antibodies starts weaning from the body. It has been suggested that coronavirus will likely become similar to a seasonal flu once the herd immunity is attained. Till then, it will continue causing outbreaks year-round and there could be multiple waves of virus transmission before achieving herd immunity. Therefore, the public needs to learn to live with it, and continue practising the best prevention measures, including wearing of masks, physical distancing, hand hygiene, and avoidance of gathering.

Drug-resistant tuberculosis coexisting with invasive candidiasis in an immunocompetent 30-year-old woman: A case report.

Invasive candidiasis coexisting with drug-resistant Mycobacterium tuberculosis (DR-TB) in the immunocompetent patient is a rare entity. We report a 30-year-old woman, nondiabetic, who presented to us with complaints of acute onset cough, breathlessness, and fever since 20 days. On thorough investigations, she was diagnosed to be suffering from coexisting drug-resistant tuberculosis and invasive candidiasis. Prompt treatment initiated at right time helped us in saving her life. The unique presentation of this case and that too in an immunocompetent female makes it an interesting case.
