Endocrinal assessment of chronic obstructive pulmonary disease patients as compared to control groups
Background: Hormones also take part in respiratory control via peripheral chemo receptors or by their local effects on the lungs and the airways. In chronic obstructive pulmonary disease patients, respiratory muscles are required to work efficiently than normal individuals to establish a sufficient respiration. Changes in serum hormone levels of COPD patients adversely affect functioning of respiratory muscles. Objective of the study was to assess endocrinal profile in COPD patient with comparable control groups.Methods: A Hospital based Case control study conducted at Department of Pulmonary Medicine, Late B.R.K.M Government Medical College, Jagdalpur, Chhattisgarh, India during July 2016 to January 2017. Study included 75 diagnosed cases of COPD in which moderate, severe, very severe COPD was 25 in each of this group (per GOLD âs guideline) and compared to age matched 25 healthy control.Results: In this study serum growth hormone and serum testosterone showed significant difference between COPD cases and control group and fair significant difference in serum FSH between COPD cases and control groups. There was no significant correlation between serum growth hormone, serum testosterone and serum FSH with COPD grading. There was no statistically difference observed in serum LH (p=0.425) level between COPD cases and control groups. Present study showed there was statistically difference in FT3, FT4 and TSH level between COPD cases and control groups. There was significant negative correlation between FT4 levels between COPD grading. But no correlation seen between COPD grading and control with respect to serum FT3 and TSH level.Conclusions: Endocrinal assessment in present study showed significant decrease in serum growth hormone and serum testosterone in COPD patients, which are anabolic hormones. Early detection and correction of such an anabolic hormonal abnormality may prevent skeletal and diaphragmatic muscle weakness, and improve respiratory drive of COPD patients
A case control study on s. uric acid and s. creatinine level in pre-eclampsia patients of a tertiary care hospital in Jabalpur district of Central India
Background: Pre-eclampsia is a multisystem disorder of pregnancy which is characterized by hypertension with proteinuria after 20 weeks of gestation in previously normotensive and non proteinuric pregnant women. Pre-eclampsia associated with intrauterine growth retardation, preterm birth, maternal and perinatal death. Serum creatinine and uric acid has been shown to play a significant role in the pathogenesis of the disease and often precede clinical manifestations. This study compares the serum creatinine and uric acid in pre -eclampsia case and normal pregnant women and to assess its role in pre-eclampsia.Methods: 158 patients of which 79 pre-eclampsia (cases) and 79 (controls) were selected randomly and were matched with their gestational age in patient who Attending ANC clinic at Department of Obstretics and Gynecology in March 2016 to August 2017. Lipid profile was estimated by the Randox imola is a compact fully automated clinical chemistry analyser.Results: Authors observed that pre-eclampsia is more common in young age pregnant women with low socioeconomic status with strenuous activities. The mean age was 24.51±3.707 years. The mean serum creatinine and urice acid value is analysed in pre-eclampia cases and compared with control group showing significantly increase (p<0.0001).Conclusions: Young age, nullyparity, low socio economic status specially labour occupation, with derangment of Serum creatinine in pregnant women were found to be more prone to develop pre-eclampsia. Proper history tacking, examination and estimation of serum creatinine and uric acid may be helpful for early diagnosis and management of preâeclampsia in order to prevent fetal and maternal complications especially in nulliparous women
Mapping assessments instruments for headache disorders against the icf biopsychosocial model of health and disability
Headache disorders have a strong impact on sufferersâ lives. However, the âcontentâ of assessment instruments addressing concepts, such as disability and quality of life (QoL), has not comprehensively been addressed. We searched SCOPUS for research papers in which outcome measures were used in adult populations of patients with migraine, tension-type headache (TTH), and cluster headache (CH). The content of single instruments was then mapped against the International Classification of Functioning, Disability, and Health. A total of 150 papers and 26 instruments were included: 15 addressed disability or impact, two addressed work-related difficulties, and nine addressed QoL. Few instruments were commonly used across the conditions and covered domains of functioning were impact on daily life activities, homework, school, and work-related tasks, leisure time, informal and family relations, pain, emotional difficulties, energy level, and impulse control. Most of the research is based on instruments that were developed for migraine, which is critical for CH, and the impact of headache disorders on work-related activities is poorly acknowledged. Further research is needed to expand the scope of headaches impact on daily life activities, and on environmental factors relevant to headache disorders to raise knowledge on the less represented areas, e.g., TTH impact
Copper/Zinc Superoxide Dismutase from the Crocodile Icefish Chionodraco hamatus: Antioxidant Defense at Constant Sub-Zero Temperature
In the present study, we describe the purification and molecular characterization of Cu,Zn superoxide dismutase (SOD) from Chionodraco hamatus, an Antarctic teleost widely distributed in many areas of the Ross Sea that plays a pivotal role in the Antarctic food chain. The primary sequence was obtained using biochemical and molecular biology approaches and compared with Cu,Zn SODs from other organisms. Multiple sequence alignment using the amino acid sequence revealed that Cu,Zn SOD showed considerable sequence similarity with its orthologues from various vertebrate species, but also some specific substitutions directly linked to cold adaptation. Phylogenetic analyses presented the monophyletic status of Antartic Teleostei among the Perciformes, confirming the erratic differentiation of these proteins and concurring with the theory of the "unclock-like" behavior of Cu,Zn SOD evolution. Expression of C. hamatus Cu,Zn SOD at both the mRNA and protein levels were analyzed in various tissues, highlighting the regulation of gene expression related to environmental stress conditions and also animal physiology. The data presented are the first on the antioxidant enzymes of a fish belonging to the Channichthyidae family and represent an important starting point in understanding the antioxidant systems of these organisms that are subject to constant risk of oxidative stress
Phylogeography and genomic epidemiology of SARS-CoV-2 in Italy and Europe with newly characterized Italian genomes between February-June 2020
: The aims of this study were to characterize new SARS-CoV-2 genomes sampled all over Italy and to reconstruct the origin and the evolutionary dynamics in Italy and Europe between February and June 2020. The cluster analysis showed only small clusters includingâ<â80 Italian isolates, while most of the Italian strains were intermixed in the whole tree. Pure Italian clusters were observed mainly after the lockdown and distancing measures were adopted. Lineage B and B.1 spread between late January and early February 2020, from China to Veneto and Lombardy, respectively. Lineage B.1.1 (20B) most probably evolved within Italy and spread from central to south Italian regions, and to European countries. The lineage B.1.1.1 (20D) developed most probably in other European countries entering Italy only in the second half of March and remained localized in Piedmont until June 2020. In conclusion, within the limitations of phylogeographical reconstruction, the estimated ancestral scenario suggests an important role of China and Italy in the widespread diffusion of the D614G variant in Europe in the early phase of the pandemic and more dispersed exchanges involving several European countries from the second half of March 2020
Whole genome sequencing and phylogenetic analysis of West Nile virus lineage 1 and lineage 2 from human cases of infection, Italy, August 2013.
A human outbreak of West Nile virus (WNV) infection caused by WNV lineage 2 is ongoing in northern Italy. Analysis of six WNV genome sequences obtained from clinical specimens demonstrated similarities with strains circulating in central Europe and Greece and the presence of unique amino acid changes that identify a new viral strain. In addition, WNV lineage 1 Livenza, responsible for a large outbreak in north-eastern Italy in 2012, was fully sequenced from a blood donor during this 2013 outbreak
Argot2: a large scale function prediction tool relying on semantic similarity of weighted Gene Ontology terms
Background: Predicting protein function has become increasingly demanding in the era of next generation sequencing technology. The task to assign a curator-reviewed function to every single sequence is impracticable. Bioinformatics tools, easy to use and able to provide automatic and reliable annotations at a genomic scale, are necessary and urgent. In this scenario, the Gene Ontology has provided the means to standardize the annotation classification with a structured vocabulary which can be easily exploited by computational methods.Results: Argot2 is a web-based function prediction tool able to annotate nucleic or protein sequences from small datasets up to entire genomes. It accepts as input a list of sequences in FASTA format, which are processed using BLAST and HMMER searches vs UniProKB and Pfam databases respectively; these sequences are then annotated with GO terms retrieved from the UniProtKB-GOA database and the terms are weighted using the e-values from BLAST and HMMER. The weighted GO terms are processed according to both their semantic similarity relations described by the Gene Ontology and their associated score. The algorithm is based on the original idea developed in a previous tool called Argot. The entire engine has been completely rewritten to improve both accuracy and computational efficiency, thus allowing for the annotation of complete genomes.Conclusions: The revised algorithm has been already employed and successfully tested during in-house genome projects of grape and apple, and has proven to have a high precision and recall in all our benchmark conditions. It has also been successfully compared with Blast2GO, one of the methods most commonly employed for sequence annotation.
