Abstract
Context Though many arrangements had been made during the first wave, multiple complaints were reported regarding the arrangements made for COVID patients. The control room was set up as a 24 × 7 administrative coordination center to attend to issues after the initial setup of COVID units. Aim To identify the major problems reported to the control room during the second wave of COVID-19 and find the related cause for the same. Methods and Materials Issues reported to the control room were recorded from April to June (2021). The control room residents were asked to allocate each problem into six categories. Next, the residents allotted a frequency score to each of the problems depending on how regularly it was reported. Secondary data from various reports were also considered. Statistical Analysis Used Data were analyzed using MS Excel software. Results Various administrative issues were identified to be due to issues in communication and coordination (23%), policy and procedures (22%), human resource and training (16%), administration and implementation (15%), infrastructure (14%), and HMIS and IT (10%). Conclusion Most frequent problems reported to the control room were related to infrastructure, policy implementation, and manpower training. After the initial implementation of new processes, there was a requirement for regular follow-up and coordination. This model of setting up an administrative control room and evidence-based approach will serve as a template for public hospitals to ensure coordination of hospital operations.

Abstract
Background Obstructive sleep apnea is a highly prevalent disorder, characterized by recurrent events of upper airway obstruction during sleep and associated with recurrent cycles of desaturation and re-oxygenation, sympathetic hyperactivity, and intra-thoracic pressure fluctuations, resulting in fragmentation of sleep and subsequent daytime fatigue with excessive sleepiness. Obstructive sleep apnea-induced bilateral tonic-clonic seizures are unheard of. We aimed to report 3 patients with previously undiagnosed obstructive sleep apnea who presented to the emergency department with new onset bilateral tonic-clonic seizure without any evidential neurological or metabolic cause. Methods Patient data were obtained from medical records from the Department of Internal Medicine, IPGMER and SSKM Hospital, Kolkata, and Belle Vue Clinic, Kolkata, India. Results Three male patients (67, 58, and 44 years old) presented with bilateral tonic-clonic seizure disorder without any underlying cause of seizures after rigorous investigations except for moderate to severe obstructive sleep apnea on polysomnography. All 2 patients were seizure-free after being treated with levetiracetam, chronic continuous positive airway pressure therapy in 2, and only continuous positive airway pressure in the other. The patients remained seizure-free on continuous positive airway pressure, even when levetiracetam was withdrawn, suggesting obstructive sleep apnea's causality in their new-onset acute seizures. Conclusion Although further investigation is required to clarify this association, underlying obstructive sleep apnea should be ruled out in patients with a first-ever bilateral tonic-clonic seizure. Whether or not continuous positive airway pressure alone could effectively treat hypoxia and deranged cortical excitability, which may lead to seizures in cases with longstanding obstructive sleep apnea, is yet to be explored.

Abstract
Recent research focused on novel aspects of sulphur and sulphur-containing molecules in fundamental plant processes has highlighted the importance of these compounds. Currently, the focus has shifted to the efficacy of hydrogen sulphide (H2 S) as signalling compounds that regulate different development and stress mitigation in plants. Accordingly, we used an in silico approach to study the differential expression patterns of H2 S metabolic genes at different growth/development stages and their tissue-specific expression patterns under a range of abiotic stresses. Moreover, to understand the multilevel regulation of genes involved in H2 S metabolism, we performed computation-based promoter analysis, alternative splice variant analysis, prediction of putative miRNA targets and co-expression network analysis. Gene expression analysis suggests that H2 S biosynthesis is highly influenced by developmental and stress stimuli. The functional annotation of promoter structures reveales a wide range of plant hormone and stress responsive cis-regulatory elements (CREs) that regulate H2 S metabolism. Co-expression analysis suggested that genes involved in H2 S metabolism are also associated with different metabolic processes. In this data-mining study, the primary focus was to understand the genetic architecture governing pathways of H2 S metabolism in different cell compartments under various developmental and stress signalling cascades. The present study will help to understand the genetic architecture of H2 S metabolism via cysteine metabolism and the functional roles of these genes in development and stress tolerance mechanisms.

Abstract
BACKGROUND: Early diagnosis of drug-resistant TB (DR-TB) is crucial in preventing the spread of the disease in the community. Introduction of upfront decentralised drug susceptibility testing to district-level as part of universal drug susceptibility testing (UDST) policy increased the feasibility of rapid and early testing for drug resistance closer to the patient and has resulted in reduced circumstances for transmission. The introduction of the first-line line-probe assay (FL-LPA), GenoType® MTBDRplus v2, has had an extensive impact on the management of multidrug-resistant TB (MDR-TB) in India.MATERIALS and METHODS: Sputum samples of patients with presumptive TB and DR-TB from selected districts of Tamil Nadu received through National TB Elimination Programme (NTEP) were subjected to FL-LPA as per programme guidelines. In this study, we present trends in genotypic resistance to isoniazid (INH) and rifampicin (RIF) during the 4 years (2016-2019) among these patients. Band patterns were analysed as per the updated GLI (Global Laboratory Initiative) LPA interpretation and reporting guidelines.RESULTS: A total of 26,349 samples were received during the study period. Smear-positive samples (n = 20231) were directly subjected to FL-LPA; smear-negative samples were cultured in liquid media and M. tuberculosis-positive cultures were tested using FL-LPA. A total of 18,441 were MTB-positive on FL-LPA. INH monoresistance, RIF monoresistance and MDR-TB was observed in respectively 8.7%, 1.1% and 3.3% of the samples. There was a decreasing trend in all types of resistance observed particularly after 2017 (P < 0.001). MDR-TB showed a steady decrease from 5.6% to 1.8%. S531L (19.5%) and S315T (61.1%) were the most common mutations identified in the rpoB and katG genes, respectively. The percentage of inhA-c-15t promoter mutation, indicating low-level INH resistance, showed a consistent increase (P < 0.001).CONCLUSION: The impact of the UDST policy on the NTEP may have led to this decreasing trend in RIF and INH resistance observed in the study period. The increase in low-level INH resistance mutation inhA-c-15t may be associated with ethionamide/prothionamide resistance, and this should be taken into account when designing DR-TB regimen.

Abstract
The whole world was shaken with the pandemic of Coronavirus Disease (COVID-19) in end of the year 2019. Due to its novel origin, it was required to follow all precautions possible. Dealing with the massive amount of infectious healthcare waste became an enormous challenge. This review identifies the impacts of the pandemic on biomedical waste management. This systematic review was made by using keywords “biomedical waste” and “COVID 19” in open access databases like PubMed, Science Direct, Scopus, Google Scholers etc. 2124 articles downloaded and 765 found duplicate and 634 not related to the topic. after scrutiny with inclusion criteria 102 articles were considered to analyze the practices related to biomedical waste management during pandemic using PRISMA guideline.. The COVID-19 waste segregation, collection, storage, transportation, and disposal are a big challenge with all stakeholders. In order to control the virus spread, strict monitoring of the complete waste management cycle is required. Adoption of appropriate guidelines is paramount to worker safety and containment of infection. Sustainable recycling methods are needed to deal with the ever-increasing plastic waste resulting from mandatory personal protective equipment (PPE) usage. The situation also demands a rethinking of the healthcare system. Overall, there was an increase in BMW generation, and municipal waste had increased globally. Pandemic preparedness requires a global public health strategy and long-term investments. This will be vital for making a robust community capable enough to fight against any public health pressures in the future, as well as the pandemic tremors. Systematized efforts from all stakeholders, at all levels, not only refines epidemic preparation but also helps to attain a sustainable development of health for a healthier future.

Abstract
Na+/H+ antiporters comprise a super-family (CPA) of membrane proteins that are found in all kingdoms of life and are essential in cellular homeostasis of pH, Na+ and volume. Their activity is strictly dependent on pH, a property that underpins their role in pH homeostasis. While several human homologues have long been drug targets, NhaA of Escherichia coli has become the paradigm for this class of secondary active transporters as NhaA crystal structure provided insight into the architecture of this molecular machine. However, the mechanism of the strict pH dependence of NhaA is missing. Here, as a follow up of a recent evolutionary analysis that identified a 'CPA motif', we rationally designed three E. coli NhaA mutants: D133S, I134T, and the double mutant D133S-I134T. Exploring growth phenotype, transport activity and Li+-binding of the mutants, we revealed that Asp133 does not participate directly in proton binding, nor does it directly dictate the pH-dependent transport of NhaA. Strikingly, the variant I134T lost some of the pH control, and the D133S-Il134T double mutant retained Li+ binding in a pH independent fashion. Concurrent to loss of pH control, these mutants bound Li+ more strongly than the WT. Both positions are in close vicinity to the ion-binding site of the antiporter, attributing the results to electrostatic interaction between these residues and Asp164 of the ion-binding site. This is consistent with pH sensing resulting from direct coupling between cation binding and deprotonation in Asp164, which applies also to other CPA antiporters that are involved in human diseases.

Abstract
Diseases due to pathogenic mycobacteria cause significant health and economic impact on humans worldwide. Although mycobacterial diseases primarily affect the lungs, the involvement of extrapulmonary organs has also gained ground, particularly among individuals with co-existing medical conditions. Besides Mycobacterium tuberculosis complex organisms, non-tuberculous mycobacteria (NTM) are also known to cause pulmonary and extrapulmonary diseases. Primary and disseminated extrapulmonary mycobacterial infections affect the brain, eye, mouth, tongue, lymph nodes of the neck, spine, bones, muscles, skin, pleura, pericardium, gastro-intestinal, peritoneum and genito-urinary system. The clinical presentation of extrapulmonary mycobacterial diseases, including systemic symptoms, of M. tuberculosis-infected cases and NTM-infected cases is similar. Moreover, extrapulmonary mycobacterial diseases are complicated by the involvement of diverse bacterial species as aetiological agents. Culture and molecular techniques are used to differentiate NTM from Mycobacterium tuberculosis and to classify sub-species of the pathogens. As sub-speciation and drug susceptibility profiling are critical factors in treating extrapulmonary NTM diseases, there are often significant delays in initiating treatment and customising the therapeutic regimen. Here, we summarise the clinical symptoms of NTM diseases in various extrapulmonary organs, and discuss the recent trends in diagnosing and treating these diseases. We also highlight the complications associated with the management of extrapulmonary NTM disease.

Abstract
This is a cross sectional study to establish that Magnetic resonance cholangiopancreatography (MRCP) could be accepted as the most effective imaging modality for the diagnosis of cholangiocarcinoma. Cholangiocarcinoma is the most common malignant tumor of the bile duct. It is much less common than hepatocellular carcinoma, accounting for 5-30% of all hepatic malignancies. Clinically suspected patients with obstructive jaundice due to cholangiocarcinoma were referred to the Department of Radiology and Imaging, Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka, Bangladesh. The study was carried out in 60 patients, of which 38(63%) were male and 22(37%) were female. Out of 60 cases 56 cases were truly diagnosed by MRCP, 4 were normal, among these 1 case was diagnosed as cholangiocarcinoma as compared with histopathology. Forty four (44) patients (73.2%) of the patients were in sixth decade of life. The overall sensitivity and specificity were found to be 98.2% and 75%. The diagnostic accuracy was 96.7% & positive predictive value was about 98%.

Abstract
Determination of age is one of the most important and vital demand in legal affairs, court and young sports, especially from 7-21 years. There is no established age determination table in our county. So we are dependent upon Galstaun, Bashu & Bashu and other European tables, which sometimes provide misinterpretation and variation of opinion. We should have our own table suitable for our nation. So, this prospective study was carried out in the Department of Radiology and Imaging of Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka, Bangladesh from July 2010 to June 2014 (five years) to assess the general skeletal maturity. Three hundred boys and girls of known date of birth were selected on random basis from Dhaka. Ages were limited within 7 to 21 year. Every 20 person for each age group, of them 10 were male and 10 were female. To observe the bony maturity, radiographs were taken at the end of their age belongs to. Thus a growth table is to be prepared for further evaluation.

Abstract
INTRODUCTION Bilateral central serous chorio-retinopathy is an unusual presentation. OBJECTIVE To report a case of pregnancy-induced bilateral central serous chorio-retinopathy. CASE A thirty-year-old woman complaining of reduced vision in both the eyes was referred for ophthalmoscopic evaluation in her third trimester of pregnancy. The best-corrected visual acuity was 6/60 in the right eye and finger counting at four meters in the left. The funduscopic examination revealed serous macular detachment with white sub-retinal exudates in both the eyes. Optical coherence tomography sections through the macula demonstrated serous elevation of the retina and retinal pigment epithelial detachment in both the eyes. The serous macular detachment resolved and the patient recovered to the visual acuity of 6/6 in both the eyes after twelve weeks of delivery. The OCT showed resolution of the sub-retinal fluid and disappearance of the sub-macular exudate in the right eye, but the resolution was partial in the left eye. CONCLUSION Pregnancy is a risk factor for CSCR and it can present with severe bilateral visual diminution.

Abstract
Extended spectrum β-lactamase producing bacteria are potential emerging pathogens and continue to be a major challenge in clinical setup worldwide. In the present study an attempt was made to study the prevalence of extended spectrum β-lactamase producing Escherichia coli and Klebsiella species from clinical isolates in a rural tertiary care hospital in West Bengal, India with their antimicrobial susceptibility as well as co-resistance pattern to different antimicrobials. A total of 179 Escherichia coli and 62 Klebsiella isolates recovered from various clinical samples of urine, pus, aural swabs and respiratory secretions (including sputum) for a period of six months were subjected to routine antimicrobial susceptibility testing and also tested for extended spectrum β-lactamase production as per NCCLS recommendations. Extended spectrum β-lactamase was detected in 32.40% of Escherichia coli and 40.32% of Klebsiella species isolates. Urine, pus and respiratory samples were common source of extended spectrum β-lactamase producers and resistance rate of these organisms to third generation cephalosporins were more than 30 to 40%. Co-resistance pattern of these extended spectrum β-lactamase producers to other commonly used antimicrobials were also statistically significant (p≤0.05). From the study it is concluded that indiscriminate use of third generation cephalosporins may be responsible for the selection of extended spectrum β-lactamase producing multidrug resistant strains in hospital setup and amikacin is a reliable drug against them.

Abstract
BACKGROUND The use of objective structured clinical examination in pediatrics is not common in undergraduate evaluation process. OBJECTIVE To evaluate the effectiveness of objective structured clinical examination as compare to conventional examination as formative assessment tool in Pediatrics. METHODS We conducted a cross sectional comparative study in defined population of 9th semester MBBS students to evaluate the effectiveness of objective structured clinical examination as comparison to conventional examination as formative assessment tool in Pediatrics. We analyzed the perception of objective structured clinical examination among the students. RESULTS Fifty-two students appeared for the objective structured clinical examination evaluation on the first day and 42 turned up for conventional examination on the next day. The 42 students who turned up for both examinations were asked to respond to the perception evaluation questionnaire. Comparison of the two examination styles showed that students fared better in objective structured clinical examination than in conventional examination both with respect to mean total score (p less than 0.001) as well as mean percentage score. Out of the 42 subjects who appeared in both examinations, all passed in objective structured clinical examination and 35 passed in conventional examination, this difference was significant by McNemar chi-square test (p = 0.016). 73.8% of the students opined in favor of objective structured clinical examination as a better formative assessment tool whereas 9.5% students preferred conventional examination. CONCLUSIONS Objective structured clinical examination a statistically significant better evaluation tool with comparison to conventional examination.

Abstract
World-wide epidemiological studies have shown that cancer of the uterine cervix is the second most common malignant disease in women. Virtually every cervical cancer (99.7%) is HPV-positive, indicating that the presence of HPV is an obligatory element in their development. The present study was conducted by Fast-PCR (within 15 min.) based diagnosis of HPV 16 and HPV 18 infection amongst patients of suspected cervical cancer, confirmed by cytological methods. Twelve women, out of a total of fifty studied cases who had positive cervical pap smears (24%) were found to be positive for HPV 16/HPV 18 infection when PCR based technique was applied. The results indicate, perhaps, a greater specificity of PCR based diagnosis, or presence of other HPV subtypes as etiological factors in the present study group confined to Southern Assam.

Abstract
OBJECTIVES We have been done the detailed deletion mapping of chromosome (chr.) 8p21.3-23 to localize the candidate tumor suppressor gene(s) (TSGs) loci as well as studied the mechanism of activation of c-myc gene, located at chr.8q24.1, by analyzing the amplification/rearrangement/HPV integration within approximately 580 kb of c-myc locus in uterine cervical carcinoma (CaCx) of Indian patients. The association between the deletions in chr.8p21.3-23 and alterations in the c-myc locus has also been analyzed. METHODS The deletion mapping of chr.8p21.3-23 was done by 15 microsatellite markers and the alterations in the c-myc locus were analyzed by Southern hybridization using the pal-1/c-myc/mlvi-4/HPV 16/18 probes in seven cervical intraepithelial neoplasia (CIN) and 55 primary uterine cervical carcinoma. The alterations in chr.8p/q have been correlated with the different clinicopathological parameters. RESULTS Three discrete minimal deleted regions with high frequencies of loss of heterozygosity (LOH) (37-43%) were identified in the chr.8p23.1-23.2 (D1), 8p23.1 (D2), and 8p 21.3-22 (D3) regions within 0.41-4.62 Mb. The deletion in the D1 region was significantly associated with the deletion in the D2 region (P = 0.03), whereas the deletion in D2 was marginally associated with the deletion in the D3 region (P = 0.07). The alterations in the c-myc locus were seen in 43% of the samples. About 35% of the samples showed coalterations in both arms of chr.8. No significant association was observed with the alterations in chr.8p/q as well as with the different clinicopathological parameters. CONCLUSIONS The deletions in chr.8p21.3-23 and the alterations in the c-myc locus are independently associated with the development of CaCx. The D1-D3 regions in chr.8p21.3-23 could harbor candidate TSGs associated with the development of this tumor. The c-myc gene was activated by amplification/rearrangement at the pal-1/c-myc/mlvi-4 loci as well as HPV integration in the pal-1 locus in this tumor.

Abstract
Of the six species of Trichosporon known to cause human infections, T. asahii is the main agent of invasive trichosporonosis. We describe an unusual case of generalized lymphadenopathy due to T, asahii in a 10-year-old boy with Job's syndrome (markedly elevated IgE with eosinophilia). The diagnosis was based on the presence of blastic conidia and hyphal elements breaking into arthroconidia in biopsied tissue of the cervical lymph node and isolation of the causal agent T, asahii in pure culture. The patient responded initially to amphotericin B therapy, but the infection recurred within 4 weeks and did not respond to therapy of liposomal amphotericin B and 5-fluorocytosine for 10 days. The patient left the hospital against medical advice.

Abstract
Phosphate solubilizing bacteria NBRI0603, NBRI2601, NBRI3246 and NBRI4003 were isolated from the rhizosphere of chickpea and alkaline soils. All four strains demonstrated diverse levels of phosphate solubilization activity under in vitro conditions in the presence of various carbon and nitrogen sources. Acid production may have contributed to phosphate solubilization, but was not the only reason for phosphate release into the medium. Among the four strains, NBRI2601 was the most efficient strain in terms of its capability to solubilize phosphorus in the presence of 10% salt, pH 12, or 45 degrees C. The strains showed varied levels of phosphate solubilization when the effects of different sources of nitrogen were examined during growth. The presence of low levels of Ca(2+) and EDTA in the medium enhanced phosphate solubilization.
