Prevalence of non-communicable disease risk factors among nursing staff in a low and middle-income country: A cross-sectional digital survey-based study.

AIM: To assess the prevalence of non-communicable disease risk factors among the nursing staff and educate them on prevention. BACKGROUND: Nursing staff is integral to the Indian community healthcare systems. Recent studies report a high prevalence of non-communicable diseases in Indian nursing staff. Therefore, data on the prevalence of non-communicable disease risk factors among nursing staff are crucial for education on prevention. DESIGN: A cross-sectional digital survey-based study. METHOD: We invited 4435 nursing staff to attend our online survey. We used a customized questionnaire for data collection, including a digitized version of the Community-Based Assessment Checklist form. A score of >4 was considered high risk and warranted screening. RESULT: Among 682 nursing staff who attended, 70% had never undergone screening for non-communicable diseases. The prevalence of non-communicable disease risk factors was significantly higher in male nursing staff. In addition, logistic regression analysis showed that age, tobacco and alcohol use, increased waist circumference, physical inactivity and family history of non-communicable diseases were significant risk factors among nursing staff. CONCLUSION: The study findings suggest that the nursing staff have suboptimal self-health concerns on non-communicable diseases. This situation warrants continued medical education, awareness campaigns on adopting a healthy lifestyle and health promotion.

Partial genomic characterization of Chromobacterium piscinae from India reveals multi drug resistance.

Species of genus Chromobacterium have been isolated from diverse geographical settings, which exhibits significant metabolic flexibility as well as biotechnological and pathogenic properties. This study describes the isolation, characterization, draft assembly, and detailed sequence analysis of Chromobacterium piscinae strain W1B-CG-NIBSM isolated from water samples from multi use community pond. The organism was characterized by biochemical tests, Matrix Assisted Laser Desorption/Ionization Time of Flight Mass Spectrometry (MALDI TOF-MS) and partial genome sequencing. The partial genomic data of Chromobacterium pisciane isolate W1B NIBSM strain was submitted to GenBank with Bio project number PRJNA803347 and accession no CP092474. An integrated genome analysis of Chromobacterium piscinae has been accomplished with PATRIC which indicates good quality genome. DNA sequencing using the illumina HiSeq 4000 system generated total length of 4,155,481 bp with 63 contig with G + C content is 62.69%. This partial genome contains 4,126 protein-coding sequences (CDS), 27 repeats region and 78 transfer RNA (tRNA) genes as well as 3 ribosomal RNA (rRNA) genes. The genomic annotation of Chromobacterium W1B depicts 2,925 proteins with functional assignments and 1201 hypothetical proteins. A repertoire of specialty genes implicated in antibiotic resistance (45 genes), drug target (6 genes), Transporter (3 genes) and virulence factor (10 genes). The genomic analysis reveals the adaptability, displays metabolic varied pathways and shows specific structural complex and various virulence factors which makes this strain multi drug resistant. The isolate was found to be highly resistant to ß-lactam antibiotics whereas it showed sensitivity towards aminoglycosides and fluoroquinolone antibiotics. Hence, the recovery of Chromobacterium piscinae from community pond evidenced for uncertain hidden source of public health hazard. To the best of authors knowledge this is first report of isolation and genomic description of C. piscinae from India.

Case report of SARS-CoV-2 with secondary Clostridioides difficile infection.

There has been an overuse of antibiotics in most patients suffering from COVID-19 which predisposes patients to hospital acquired C. difficile Infection (CDI). Also, COVID infection of the gastrointestinal tract also predisposes the patient to CDI. We here present a fatal case of SARS-CoV-2 coinfection with CDI.

AutomAted RepeaT Identifier (AARTI): A tool to identify common, polymorphic, and unique microsatellites.

Here we are presenting an automated computational pipeline used to mine 5976 mitochondrial genomes to identify common, polymorphic, and unique microsatellites also known as simple sequence repeats (SSRs). Microsatellites are repetitive motifs of 1-6 bases in a DNA sequence. Due to their abundance and highly polymorphic nature, microsatellites have become one of the widely used molecular/genetic markers valuable for many studies including gene tagging, genetic diversity, and species identification. Several computational tools dedicated to mine and categorize microsatellites in nucleotide sequences were developed; however, there is no tool which can identify unique, common and polymorphic microsatellites between each pair of nucleotide sequences. To explore such microsatellites, we have developed a fully automated computational pipeline named AutomAted RepeaT Identifier (AARTI). The AARTI is the only tool till date, which identifies common, polymorphic, and unique microsatellites between each pair of nucleotide sequences. The computational pipeline was constructed using the PERL programming language and the web server for the pipeline was developed with the help of PHP, HTML, CSS, and JavaScript. It was successfully tested to reproduce the results of previous study on 7 mitochondrial genomes of genus Orthotrichum. Moreover, the pipeline was also applied on 5846 (Metazoa) and 130 (Viridiplantae) mitochondrial genomes. The AARTI is freely available at https://lms.snu.edu.in/aarti/ and will certainly accelerate the studies of length variation in microsatellites between species. Additionally, it will be useful in comparative genomic studies, for the computational characterization of microsatellites, and has the potential to be a routine genome analysis pipeline for mitochondrial genomes.

Anxiety: An ignored aspect of Parkinson's disease lacking attention.

Parkinson's disease (PD) is a progressive neurodegenerative disease which affects millions of population worldwide. It is characterized by motor symptoms such as excessive tremor, bradykinesia, rigidity, postural instability and non-motor symptoms include neuropsychiatric complications like anxiety, depression, insomnia and cognitive impairment, orthostatic hypotension, sexual dysfunction and gastrointestinal complications. Treatment of anxiety in PD poses extensive challenge to global healthcare which makes it urgent to develop innovative treatment for the better management of the disease. The gold standard treatment by Levodopa provides symptomatic relief and its effect on neuropsychiatric complications like anxiety is elusive. Presence of anxiety worsens the condition and challenges therapeutic management of the PD. The in-depth analysis and understanding the molecular mechanism and pathophysiological pathways associated with the onset of anxiety in PD is essential. The disturbances in serotonergic, adrenergic and GABAergic neurons and hypothalamic pituitary adrenal axis play a significant role in the pathophysiology of anxiety. The drugs like Selective Serotonin Reuptake Inhibitors, tricyclic antidepressants and benzodiazepines are useful in the management of anxiety but due to severe side effects and progression of the disease it results in the failure of treatment. The present review imparts an insight in the management of anxiety in PD by understanding molecular mechanism and application of alternative treatment options which can enlighten the perception of researchers towards better therapeutic management of the disease.

Proteotoxicity and mitochondrial dynamics in aging diabetic brain.

Impaired neuronal proteostasis is a salient feature of both aging and protein misfolding disorders. Amyloidosis, a consequence of this phenomena is observed in the brains of diabetic patients over the chronic time period. These toxic aggregates not only cause age-related decline in proteostasis, but also dwindle its ability to increase or restore the chaperones in response to any stressful condition. Mitochondria acts as the main source of energy regulation and many metabolic disorders such as diabetes have been associated with altered oxidative phosphorylation (OxPhos) and redox imbalance in the mitochondria. The mitochondrial unfolded protein response (UPRmt) acts as a mediator for maintaining the mitochondrial protein homeostasis and quality control during such conditions. Over a long time period, these responses start shutting off leading to proteotoxic stress in the neurons. This reduces the buffering capacity of protein network signalling during aging, thereby increasing the risk of neurodegeneration in the brain. In this review, we focus on the proteotoxic stress that occurs as an amalgamation of diabetes and aging, as well as the impact of mitochondrial dysfunction on the neuronal survival affecting the diabetic brain and its long term consequences on the memory changes.

Experiences of Living with Intestinal Ostomy: A Qualitative Meta-Synthesis.

AIMS AND OBJECTIVES: The aim and objective of the study was to identify, compare, and synthesize published qualitative evidence to have in-depth understanding of experiences of patients living with intestinal ostomy. BACKGROUND: Over the past two decades, there have been numerous qualitative studies published depicting intense experiences of stoma patients brought about by the need to adapt with changing conditions following stoma creation. Synthesizing the findings of these studies can improve the understanding among health-care providers of needed support and care for ostomates. DESIGN: This was a qualitative meta-synthesis. METHODS: Published articles were identified from the Medline, CINAHL, SciELO, PsycINFO, PubMed, WOS, Google Scholar and a hand search through selected journals published since 2000, and from references lists. Thirteen articles were selected using the predefined criteria. RESULTS: A total of 222 patients, aged between 14 and 83 years from 13 studies, were identified for data collection. Ninety-seven were male and the rest of them were female. The themes identified were physical problems, psychological issues, social relations, environmental impact, and coping and adaptation to stoma. CONCLUSIONS: The findings of the study identified numerous challenges and limitations in the life of patients with stoma. However, improving their skills of using problem-solving coping strategies and their interactions with other ostomates can help them to live a better and well-adjusted life.

Detection and genetic characterization of porcine circovirus 3 (PCV3) in pigs in India.

Porcine circovirus type 3 (PCV3), a novel circovirus, has been reported recently from major swine growing countries globally, and the virus is associated with diseases like porcine dermatitis, nephropathy syndrome and reproductive failure. This report describes the identification of PCV3 associated with reproductive failure in sows and piglet mortality and circulation of the virus in healthy pigs in India. The pathological changes in various tissues from stillborn piglet and characterization of the virus genomes were reported. The genome sequences of Indian PCV3 strains showed 91.4%-99.8% nucleotide identity with other sequences of PCV3 strains circulating worldwide. The phylogenetic analysis showed clustering of Indian strains into a separate group with the isolate from USA (MN/2016) under PCV3a genotype. The results confirmed the circulation of PCV3 in Indian pigs and its association with clinical cases. This study speculates emergence of PCV3 as an important pig pathogen in the country, which warrants the thorough investigation on PCV3 epidemiology, pathogenesis and to implement the control measures.

Cultivable microbiota and pulmonary lesions in polymicrobial bovine pneumonia.

In the present study, the spectrum of bacterial pathogens in the nasal shedding during disease process and in pneumonic lungs of dead animals was studied. A total of 288 clinical samples from cattle and buffaloes comprising of nasal swabs, blood, tracheal swabs, heart blood and lung tissue samples were collected from diseased (n = 190) and dead animals (n = 98). The recovered bacterial isolates were characterized by biochemical reactions, Matrix Assisted Laser Desorption/Ionization Time of Flight Mass Spectrometry (MALDI TOF-MS) and the 16S rRNA sequence analysis. The predominant bacterial isolates associated were Pasteurella multocida, Pseudomonas aeruginosa, Escherichia coli, Klebsiella pneumoniae and Staphylococcus aureus. The emerging pathogens causing bovine pneumonia identified were Leclercia spp., Stenotrophononas maltophila and Staphylococcus sciuri. Bacteriological examination of pneumonic lungs samples revealed 96.9% samples to be positive for polymicrobial isolation. Macroscopical lesions of lungs exhibited various stages and types of pneumonia with variable degree of haemorrhages, oedema and emphysema. Histopathologically, the fibrinous bronchopneumonia was observed to be the most frequent lesions seen in bovine pneumonia. Multi-drug resistance (MDR) was observed in 10% of P. multocida isolates. The resistance was seen for penicillin, cephalosporins and fluoroquinolones. Multi-drug resistance was seen in 90% of the E.coli tested. K. pneumoniae, E. hormaechei, E. cloacae, P. putida and Leclercia spp. identified were found to be multi-drug resistant. Understanding the etiological diversity of bacterial pathogens of bovine pneumonia may provide information for the better choice of therapeutics and health management.

Apparent prevalence and risk factors associated with occurrence of Coxiella burnetii infection in goats and humans in Chhattisgarh and Odisha, India.

Coxiella burnetii is one of the most contagious pathogen associated with Q fever in humans, while, ruminants act as important source of infection for humans. In the present cross sectional study, a total of 464 samples were collected from 218 goats comprising of 218 sera, 218 blood and 28 milk from various parts of Chhattisgarh and Odisha region, India. Besides, environmental (33; soil- 4, faecal- 10, feed-6, drainage water- 6, drinking water- 7) and rodent (38) samples were also collected from the premises of the animals. Human sera samples (93) were collected from same sampling area comprised of workers at an organized dairy farm (43), and farmers (50). The samples were subjected to PCR targeting the trans and com1 genes and detection of antibodies using commercial ELISA kits. An overall 14.22% (95% CI: 10.2-19.47%) of the goat samples were positive using either PCR or ELISA. While, by using PCR and ELISA, 11.93% (26/218) and 9.63% (21/218) of the samples were positive for C. burnetii. A higher seropositivity (46.24%; 95% CI: 36.46-56.32%) was observed for antibodies against C. burnetii in samples collected from humans. None of the human, environmental and rodent samples were positive for C. burnetii using PCR. This seems to be the first cross sectional study to focus the hidden threat of coxiellosis among goat population and associated risk factors in India.

Detection of Mycoplasma pneumoniae and Legionella pneumophila in Patients Having Community-Acquired Pneumonia: A Multicentric Study from New Delhi, India.

Atypical pathogens including Mycoplasma pneumoniae and Legionella pneumophila are increasingly recognized as important causes of community-acquired pneumonia (CAP). Mycoplasma pneumoniae accounts for 20-40% of all CAP and L. pneumophila is responsible for 3-15% of cases. The paucity of data from India in this regard prompted us to conduct this prospective multicentric analysis to detect the prevalence of M. pneumoniae and L. pneumophila in our geographical region. A total of 453 patients with symptoms of pneumonia and 90 controls with no history of lower respiratory tract infections were included in the study. A duplex polymerase chain reaction (PCR) targeting 543 bp region of P1 adhesin gene of M. pneumoniae and 375 bp region of macrophage infectivity potentiator (mip) gene of L. pneumophila was standardized for simultaneous detection of these atypical pathogens. Respiratory secretions, blood, and urine samples were collected from each patient and control and were subjected to duplex PCR, culture and serology for M. pneumoniae and L. pneumophila. Urine samples were subjected for detecting L. pneumophila antigen. Among the 453 patients investigated for M. pneumoniae, 52 (11.4%) were positive for IgM antibodies, 17 were positive by culture, and seven tested positive by PCR (P1 gene). Similarly for L. pneumophila, 50 cases (11%) were serologically positive for IgM antibodies, one was positive by PCR (mip gene) and urine antigen detection. A total of eight samples were positive by duplex PCR for M. pneumoniae P1 gene (N = 7) and L. pneumophila mip gene (N = 1). Of the 90 controls, two samples (2.2%) showed IgM positivity, and 15 (16.7%) showed IgG positivity for M. pneumoniae. For L. pneumophila, three samples (3.3%) tested positive for IgM, and 12 (13.3%) tested positive for IgG antibodies. The study findings indicate the presence of M. pneumoniae and L. pneumophila in our geographical region, and a combination of laboratory approaches including PCR, culture, and serology is required for effective detection of these agents.
