OCLC Number/Unique Identifier: 9124702324

Introduction: Suicidal behavior in teenagers constitutes a health problem that, given the necessary measures of social isolation taken by the global emergency of the COVID-19 pandemic, must generate timely actions for its prevention and control from the public health services. Objective: To propose an action plan for the prevention of suicide in teenagers of the Remedios municipality, subjected to voluntary home confinement during the COVID-19 pandemic. Methods: an observational, descriptive, cross-sectional study was carried out in the “XXX Anniversary” Teaching Community Polyclinic of the municipality Remedios. We worked with the population of 25 teenagers between 12 and 19 years old who made suicide attempts in the period 2019-2021. The empirical methods used were: bibliographic and documentary review, participant observation, focus group, semi-structured interview and questionnaire. Results: The suicide attempt was common in female teenagers aged 17 to 19 years not identified as risk, the lack of motivation due to the study activity and the previous suicide attempts by ingesting psychotropic drugs without serious intention of dying predominated. The most frequent psychological disorders were emotional disorders, stress, depression, irritability, apathy and insomnia. Actions are presented for the prevention of suicide and promote behaviors that contribute to mental health in the context of COVID-19. Conclusion: The prevention of suicidal behavior in teenagers in conditions of social isolation due to COVID-19, must include actions that facilitate the coping with stress, intra-family communication and resilience.

Institutional capacity of health care institutes for diagnosis and management of common genetic diseases - A study from a north coastal district of Andhra Pradesh

Published on: 28th June, 2021

OCLC Number/Unique Identifier: 9124855034

Background: In India, the genetic disease is a disregarded service element in the community health- protection system. This study aims to gauge the accessibility of services for treating genetic disorders and also to evaluate the practices on deterrence and management services in the district health system. Methods: A cross-sectional survey of selected health amenities from 454 medical officers (MO’s), 94 accredited social health activist (ASHAs) workers, 86 multipurpose health assistant-female (MPHA-F), 34 multipurpose health assistant-male (MPHA-M), 14 multipurpose health supervisors-female (MPHS-F), 10 multipurpose health supervisors-male (MPHS-M), 6 multipurpose health extension officer/ community health officer (MPHEO/CHO), 10 public health nurse (PHN), 45 lab technicians (LT’s) working in the government health sector and 254 in the private health sector, 409 nursing staff working in the government health sector and 995 in the private health sector, 15 primary health centers (PHC’s), 4 community health centers (CHC’s), 1 district government hospital (DGH), 3 referral hospitals (RH’s). From the side of private health institutions 25 corporate hospitals (CH’s), 3 medical colleges (MC’s), and 25 diagnostic laboratories (DL’s) were conducted. Results: The findings show that adequate staff was in place at more than 70% of health centers, but none of the staff have obtained any operative training on genetic disease management. The largest part of the DH’s had rudimentary infrastructural and diagnostic facilities. However, the greater part of the CHC’s and PHC’s had inadequate diagnostic facilities related to genetic disease management. Biochemical, molecular, and cytogenetic services were not available at PHC’s and CHC’s. DH’s, RH’s, and all selected medical colleges were found to have offered the basic Biochemical genetics units during the survey. In 24% of CH’s, the basic biochemical units are available and 32% (8 out of 25) of DL’s have the advanced biochemical genetics units by study. Molecular genetics units were found to be available in 28% (7 out of 25) of DL’s during the study. About 6 (24%) diagnostic centers of cytogenetic laboratories were located in the Visakhapatnam district under the private sector. Conclusion: The district health care infrastructure in India has a shortage of basic services to be provided for the genetic disorder. With some policy resolutions and facility strengthening, it is possible to provide advanced services for a genetic disorder in the district health system.

A retrospective review of the factors that negatively influenced the eradication of polio in South-South, Nigeria

Published on: 30th July, 2021

OCLC Number/Unique Identifier: 9186964198

Background: The endemic nature of poliomyelitis in Nigeria was a source of concern to many given the global efforts aimed at eradicating the scourge. In this study, the factors that influenced the eradication of this malady in South-South Nigeria (Akwa Ibom and Cross River State) were investigated. Four null hypotheses, drawn on these factors (including culture belief, religious difference, language and the prevalence of ethnic conflict) guided the investigation. The main thrust of this study was to examine how socio-cultural factors negatively influenced the eradication of polio in the study area. Methods: Through stratified random and purposive sampling techniques, 600 adult men and women who had children were selected for the study. A structured questionnaire constructed by the researcher was used in data collection. Data analysis was carried out using one-way ANOVA and independent t-test statistical tools. Results: The findings were that cultural belief and religious affiliation exerted significant influence on the people’s effort towards polio eradication. Conclusion: The study indicated that the low use of health services by the people was brought about by variation in these variables. Among other things, it was suggested that continuous awareness campaigns be carried out to educate the people on the need for immunization anchored in science and technology.

State Department had evacuated a number of Americans from the U.S. consulate in Guangzhou, China after they experienced unexplained health issues. A group of U.S. diplomats stationed in China have been brought back to the states after being inflicted by a mystery illness that reportedly resembles the brain injuries previously suffered by staff in Cuba. At the end of the December 2018 we have found a medicine fully treating the damages caused the Frey Effect of Microwave and other types of Sonic Weapons in Human’s internal, endogenous organs. I am proposing to use Naphasoline nitrate, (former) nasal decongestant, to treat Carcinogenesis of the Human’s internal, endogenous organs caused by Sonic Weapons through the release and cleaning of the Lymphatic ways in patients with colorectal, colon, pancreatic, breast, etc., cancer. I have proved this healing effect of the Naphazoline nitrate on myself during treatment in last months of the year 2018.

Synthesis of NaYF4:Yb,Er@SiO2@Ag core-shell nanoparticles for plasmon-enhanced upconversion luminescence in bio-applications

Published on: 12th October, 2019

OCLC Number/Unique Identifier: 8278640404

The present report highlights our results on synthesis of NaYF4:Yb,Er@SiO2@Ag core–shell nanoparticles (CSNPs) for plasmon-enhanced upconversion luminescence (UCL). Hydrophilic surface UCL nanoparticles (UCLNPs) as cores were obtained by precipitation of Rare Earth Elements (REE) chlorides from water-alcohol solutions. The formation of a hydrophobic surface of α-NaYF4:Yb,Er NPs was achieved by thermolysis method at 280 °C and β-NaYF4:Yb,Er by precipitation method in nonpolar medium at 320 °C. Silica shell was formed by the modified Stöber method on the surfaces of UCLNPs with different polarity and phase composition. A mixture of hexane-cyclohexane-isopropyl alcohol was used as a medium for the formation of mononuclear CSNPs on hydrophobic surfaces of cores with different thicknesses of the silica shell: 5 nm and 14 nm. Formation of a predetermined thickness of silica shell was carried out by introducing a precise quantity of TEOS taking into account the size of core NPs with molar ratio TEOS: H2O equal to 1:6. The morphology and phase composition of cores and CSNPs were examined by transmission electron microscopy and selected area electron diffraction, respectively. The insertion of Ag NPs into the structure of NaYF4:Yb,Er@SiO2 was carried out in parallel at the stage of shell formation, which made this synthesis a one-step process. The control of the size of Ag NPs was implemented through the use of a colloidal solution of NPs of the cluster structure by changing the polarity of the medium. The highest intensity enhancement of 85-fold with 5 nm and 29-fold with 14 nm shell thickness was recorded, respectively. For the first time, tests on bioimaging of neutrophil cells by those CSNPs are demonstrated.

Mesoscopic irreversible thermodynamics of morphological evolution kinetics of helical conformation in bioproteins ‘DNA’ under the isothermal isobaric conditions

Published on: 11th March, 2020

OCLC Number/Unique Identifier: 8570215259

The morphological evolution kinetics and instabilities of alpha helical peptide 3.613, which involves large amount of stored torsional elastic deformation energy (3-40 eV/molecule), is formulated by the variational method based on the connection between the rates of internal entropy production and the changes in the global Gibbs free energy, assuming that one has isobaric irreversible processes under the isothermal conditions. The present mesoscopic nonequilibrium thermodynamic approach relies on the fact that the global Gibbs free energy of helical conformation involves not only the bulk Gibbs free energy of the amino-acid back bone structure but also the interfacial Gibbs free energy of the enclosing cylindrical shell or the cage associated with the side-wall molecular branches, and their interactions with the immediate surroundings. The proposed variational analysis applied directly on the proposed macro-model has furnished a nonlinear integral equation in terms of the normalized and scaled internal and external variables. This allows us to track down the motion of the total pitch height of the alpha polypeptide along the well-defined trajectories in the displacement-time space, dictated not only by the initial configuration of the helix but also through the gradients of the global Gibbs free energy of the strained helical conformation as the main driving force. In the negative manifold, there is a well-defined region below the dynamic instability regime, in which the helical conformation can evolve towards the nonequilibrium stationary states by expanding, or contracting, depending upon whether the interfacial free energy and/or the applied stress system are below or above the well-defined thresholds level dictated by the initial pitch height. The highest life time may be realized along that trajectory, which follows up the threshold level of the interfacial specific Gibbs free energy, which is gs = -315 erg/cm2. In the upper region of the negative manifold, the helical conformations are driven by the very large applied uniaxial tension or the negative pressure induced by the thermal expansion, in the range of p > 1GPa and/or the strong negative interfacial free energies [3-4 pH] or their combinations, they show strong kinematic instabilities, which can cause not only the accelerated unfolding phenomenon but also cause large extensions that end up with the catastrophic decimations by ruptures and fragmentations. In the positive manifold, the aging behavior of the polypeptide follows up a S-shape path having rather speedy aging behavior compared to the negative manifold, which is separated from by a well-defined boundary, which represents the isochoric path having longest relaxation times, which can be achieved with great stability. Finally, one could attempt to estimate the upper limit of the relaxation time of aging for the modern hominin, from samples of exceptional preservations, relying on the present nonequilibrium theory as well as on the very limited knowledge on the post-mortem DNA and the present pitch heights of the modern hominin, which is found to be about 25,840 yrs, with a life expectation of 451,800 yrs. These figures are very close to those calculated for Neanderthals (SH), which are found to be 31,820 yrs and 499,100 yrs, respectively.

The Trans-zoonotic Virome interface: Measures to balance, control and treat epidemics

Published on: 9th April, 2020

OCLC Number/Unique Identifier: 8870064677

The global virome: The viruses have a global distribution, phylogenetic diversity and host specificity. They are obligate intracellular parasites with single- or double-stranded DNA or RNA genomes, and afflict bacteria, plants, animals and human population. The viral infection begins when surface proteins bind to receptor proteins on the host cell surface, followed by internalisation, replication and lysis. Further, trans-species interactions of viruses with bacteria, small eukaryotes and host are associated with various zoonotic viral diseases and disease progression. Virome interface and transmission: The cross-species transmission from their natural reservoir, usually mammalian or avian, hosts to infect human-being is a rare probability, but occurs leading to the zoonotic human viral infection. The factors like increased human settlements and encroachments, expanded travel and trade networks, altered wildlife and livestock practices, modernised and mass-farming practices, compromised ecosystems and habitat destruction, and global climate change have impact on the interactions between virome and its hosts and other species and act as drivers of trans-species viral spill-over and human transmission. Zoonotic viral diseases and epidemics: The zoonotic viruses have caused various deadly pandemics in human history. They can be further characterized as either newly emerging or re-emerging infectious diseases, caused by pathogens that historically have infected the same host species, but continue to appear in new locations or in drug-resistant forms, or reappear after apparent control or elimination. The prevalence of zoonoses underlines importance of the animal–human–ecosystem interface in disease transmission. The present COVID-19 infection has certain distinct features which suppress the host immune response and promote the disease potential. Treatment for epidemics like covid-19: It appears that certain nutraceuticals may provide relief in clinical symptoms to patients infected with encapsulated RNA viruses such as influenza and coronavirus. These nutraceuticals appear to reduce the inflammation in the lungs and help to boost type 1 interferon response to these viral infections. The human intestinal microbiota acting in tandem with the host’s defence and immune system, is vital for homeostasis and preservation of health. The integrity and balanced activity of the gut microbes is responsible for the protection from disease states including viral infections. Certain probiotics may help in improving the sensitivity and effectivity of immune system against viral infections. Currently, antiviral therapy is available only for a limited number of zoonotic viral infections. Because viruses are intracellular parasites, antiviral drugs are not able to deactivate or destroy the virus but can reduce the viral load by inhibiting replication and facilitating the host’s innate immune mechanisms to neutralize the virus. Conclusion: Lessons from recent viral epidemics - Considering that certain nutraceuticals have demonstrated antiviral effects in both clinical and animal studies, further studies are required to establish their therapeutic efficacy. The components of nutraceuticals such as luteolin, apigenin, quercetin and chlorogenic acid may be useful for developing a combo-therapy. The use of probiotics to enhance immunity and immune response against viral infections is a novel possibility. The available antiviral therapy is inefficient in deactivating or destroying the infecting viruses, may help in reducing the viral load by inhibiting replication. The novel efficient antiviral agents are being explored.

C3D data based on 2-dimensional images from video camera

Published on: 13th January, 2021

OCLC Number/Unique Identifier: 8899341920

The Human three-dimensional (3D) musculoskeletal model is based on motion analysis methods and can be obtained by particular motion capture systems that export 3D data with coordinate 3D (C3D) format. Unique cameras and specific software are essential for analyzing the data. This equipment is quite expensive, and using them is time-consuming. This research intends to use ordinary video cameras and open source systems to get 3D data and create a C3D format due to these problems. By capturing movements with two video cameras, marker coordination is obtainable using Skill-Spector. To create C3D data from 3D coordinates of the body points, MATLAB functions were used. The subject was captured simultaneously with both the Cortex system and two video cameras during each validation test. The mean correlation coefficient of datasets is 0.7. This method can be used as an alternative method for motion analysis due to a more detailed comparison. The C3D data collection, which we presented in this research, is more accessible and cost-efficient than other systems. In this method, only two cameras have been used.

Fecal storage condition induces variations of microbial composition and differential interpretation of metagenomic analysis

Published on: 17th March, 2021

OCLC Number/Unique Identifier: 8999916387

Advances in metagenomics have facilitated population studies of associations between microbial compositions and host properties, but strategies to minimize biases in these population analyses are needed. However, the effects of storage conditions, including freezing and preservation buffer, on microbial populations in fecal samples have not been studied sufficiently. In this study, we investigated metagenomic differences between fecal samples stored in different conditions. We collected 46 fecal samples from patients with lung cancer. DNA quality and microbial composition within different storage Methods were compared throughout 16S rRNA sequencing and post analysis. DNA quality and sequencing results for two storage conditions (freezing and preservation in buffer) did not differ significantly, whereas microbial information was better preserved in buffer than by freezing. In a metagenomic analysis, we observed that the microbial compositional distance was small within the same storage condition. Taxonomic annotation revealed that many microbes differed in abundance between frozen and buffer-preserved feces. In particular, the abundances of Firmicutes and Bacteroidetes varied depending on storage conditions. Microbes belonging to these phyla differed, resulting in biases in population metagenomic analysis. We suggest that a unified storage Methods is requisite for accurate population metagenomic studies.

Assessment and sensitive analysis of biological water risks in water resources with application of classical mass transfer computations

Published on: 9th June, 2021

OCLC Number/Unique Identifier: 9124650394

Due to the urgent need for water in all parts of industrial or developing societies, water supply, and transmission facilities are suitable targets for biological risks. Given that even a short interruption in water supply and water supply operations has a great impact on daily activities in the community, the deliberate contamination of urban water resources has irreparable consequences in the field of public health, and the economy of society will follow. Unfortunately, most officials in the public health control departments in our country have received limited training in detecting accidental or intentional contamination of water resources and dealing with the spread of waterborne diseases both naturally and intentionally. For this reason, there is low preparedness in the responsible agencies to deal with waterborne diseases during biological risks. In the first step of this research, a review study has been conducted on water biological risks and operational strategies to deal with them. In the following, it has studied how Escherichia coli (E. coli) bacteria spread in aqueous media. In this regard, the kinetic model of the studied microorganism was analyzed based on the implementation of (Fick Law) in polar coordinates and the combination of (Dirac Distribution) with (Legendre polynomial) distribution. Finally, after studying the factors affecting the microbial pollutant emission coefficient, the effects of all three factors of linear velocity, linear motion time period, and angle of motion on the pollutant emission flux and biofilm diffusion time in the water supply network environment were investigated. Studies have shown that the linear velocity parameter of Escherichia coli with a nonlinear relationship has the greatest effects on the release of microbial contaminants.

Simulating the dispersion of poisonous organic chemical compounds in wastewater treatment process through the active sludge method using the TOXChem model

Published on: 24th June, 2021

OCLC Number/Unique Identifier: 9124851637

Naturally, microorganisms decompose the organic material existing in nature, both in the presence or absence of oxygen. The majority of materials such as poisonous chemical compounds, heavy metals, would prevent the treatment process from taking place, lead to the entry of these contaminants into the environment results in the emergence of numerous diseases. In the present study, using the TOXChem4.1 simulation model, attempts were made to simulate a wastewater treatment plant and then assess the dispersions of contaminants including 1,2-Dimethylnaphthalene, 1,3-Dinitropyrene, 1,6-Dimethylnaphthalene, 1,6-Dinitropyrene, and 17a-ethinylestradiol (EE2) in concentrations of a common scenario. The results of computer simulations showed that the EE2 contaminant is of the highest percentage of decomposition among others, due to its wider chemical structure. Consequently, it is clear that such contaminant is of the highest mass in the sludge exiting the treatment plant. In addition, the results of the simulations demonstrated that the highest volumes of gaseous pollutants take place in the modulation and initial sedimentation units.

The PVSG/WHO versus the Rotterdam European clinical, molecular and pathological diagnostic criteria for the classification of myeloproliferative disorders and myeloproliferative neoplasms (MPD/MPN): From Dameshek to Georgii, Vainchenker and Michiels 1950-2018

Published on: 17th April, 2019

OCLC Number/Unique Identifier: 8164019922

The present article extends the PVSG-WHO criteria into a simplified set of Rotterdam and European Clinical, Molecular and Pathological (RCP/ECMP) criteria to diagnose and classify the myeloproliferative neoplasms (MPNs). The crude WHO criteria still miss the masked and early stages of ET and PV. Bone marrow histology has a near to 100% sensitivity and specificity to distinguish thrombocythemia in BCR/ABL positive CML and ET, and the myelodysplastic syndromes in RARS-T and 5q-minus syndrome from BCR/ABL negative thrombocythemias in myeloproliferative disorders (MPD). The presence of JAK2V617F mutation with increased erythrocytes above 6x1012/L and hematocrit (>0.51 males and >0.48 females) is diagnostic for PV obviating the need of red cell mass measurement. About half of WHO defined ET and PMF and 95% of PV patients are JAK2V617F positive. The combination of molecular marker screening JAK2V617F, JAK2 exon 12, MPL515 and CALR mutations and bone marrow pathology is 100% sensitive and specific for the diagnosis of latent, early and classical ECMP defined MPNs. The translation of WHO defined ET, PV and PMF into ECMP criteria have include the platelet count above 350 x109/l, mutation screening and bone marrow histology as inclusion criteria for thrombocythemia in various MPNs. According to ECMP criteria, ET comprises three distinct phenotypes of true ET, ET with features of early (“forme fruste” PV), and ET with a hypercellular erythrocythemic, megakaryocytic granulocytic myeloproliferation (EMGM or masked PV). The ECMP criteria clearly differentiate early erythrocythemic, prodromal and classical PV from congenital polycythemia and idiopathic or secondary erythrocytosis. The burden of JAK2V617F mutation in heterozygous ET and in homozygous PV is of major clinical and prognostic significance. JAK2 wild type MPL515 mutated normocellular ET and MF lack PV features in blood and bone marrow. JAK2/MPL wild type hypercellular ET associated with primary megakaryocytic granulocytic myeloproliferation (PMGM) is the third distinct CALR mutated MPN. The translation of WHO into ECMP criteria for the classification of MPNs have a major impact on prognosis assessment and best choice for first line non-leukemogenic approach to postpone potential leukemogenic myelopsuppressive agents as long as possible in ET, PV and PMGM patients.

Bone marrow histology in CALR mutated thrombocythemia and myelofibrosis: Results from two cross sectional studies in 70 newly diagnosed JAK2/MPL wild type thrombocythemia patients

Published on: 21st June, 2019

OCLC Number/Unique Identifier: 8180078896

The clinical phenotypes in 268 JAK2V617F mutated MPN patients in the Seoul study were PV in 101, ET in 95 and MF in 78 and 56 CALR mutated MPN consisted of PV in none, ET in 40 and MF in 16 cases. CALR mutated MPN patients were younger than JAK2V617F mutated MPN patients (mean ages 57.5 and 66 years), had lower values for values for leukocytes (8.6 vs 11.9x109/L) and higher values for platelets (898 vs 643x109/L respectively). Bone marrow histopathology in 268 JAK2V617F mutated MPN patients in the Seoul study was featured by an increased erythropoiesis and megakaryopoiesis (EM) in 13.5%, an increased erythropoiesis, megakaryopoiesis and granulopoiesis (EMG) in 31.3%, a normocellular megakaryocytic (M) proliferation in 29,1%, a megakaryocytic and granulocytic (MG) proliferation with a relative reduction of erythropoiesis in post-ET and Post-PV myelofibrosis in 26.2%. The bone marrow histology in 56 cases of CALR mutated MPN show a predominantly increased megakaryopoiesis (M) in two thirds and an increased megakaryopoiesis and granulopoiesis (MG) with a decreased erythropoiesis in one third. Thirteen consecutive CALR MPN patients in the Belgian & Dutch cross sectional study presented with thrombocythemia associated with a typical PMGM bone marrow histology in 11 and myelofibrosis in 2 cases. All 11 thrombocythemia and 2 myelofibrosis CALR mutated MPN patients did not have constitutional symptoms and did not suffer from microvascular erythromelalgic disturbances, major thrombosis at platelet counts between 400 and 1000x109/L. There was an occurrence of hemorrhages at platelet counts above 1000x109/L in two CALR thrombocythemia cases. Bone marrow histology of CALR mutated thrombocythemia in the Seoul and Belgian/Dutch study showed loose clusters of large megakaryocytes (M) with bulky, cloud-like nuclei with a normal or a minor reduction of erythropoiesis and no increase in reticulin fibers grade 0 or 1 (RF 0 or 1). CALR thrombocythemia patients show various degrees of increased bone marrow cellularity due to dual megakaryocytic and granulocytic (MG) proliferation featured by large megakaryocytes with roundish bulky nuclear forms and cloud-like clumsy nuclei, which are almost never seen in JAK2V617F ET and PV. Assessment of allele burden is an independent and most important factor for all molecular variants MPN disease burden. Overt myelofibrosis with advanced post PV and or ET myelofibrosis at the bone marrow level occurred in one third (30%) of 208 evaluable JAK2 MPN patients and in 8 (14%) of 56 CALR MPN patients in the Seoul study.

Neurobiology of Common Sleep Disorders

Published on: 14th August, 2018

OCLC Number/Unique Identifier: 7844539109

Sleep disorders in human are common and detrimental to general health of all age groups. While the neurobiological mechanisms of sleep disorders are not yet fully understood, recent advances in research on the sleep-wake regulation mechanism, genetic and epigenetic factors, cognitive, emotional and physiological changes related to sleep have shed light on the mechanistic basis of sleep disorders. Over the past two decades, studies in Drosophila have yielded new insights into basic questions regarding sleep function and regulation. More recently, powerful genetic approaches in the fly have been applied toward studying primary human sleep disorders and other disorders associated with dysregulated sleep. In this review, we discussed recent advances in neurobiology of sleep-wave cycle and common sleep disorders. Understanding these mechanisms are important in the diagnosis, treatment and prevention of these common disorders.

Correlation of plasma protein from MDS, young and elderly patients by SDS-page

Published on: 11th November, 2019

OCLC Number/Unique Identifier: 8330254423

Summary: Myelodysplastic Syndrome (MDS) is a heterogeneous group of clonal hematopoietic malignancies characterized by progressive cytopenias, ineffective hematopoiesis, bone marrow hypercellularity and transformation to acute myeloid leukemia (AML). Objectives: Identify plasma proteins from MDS patients and from two healthy controls groups (young and elderly) by SDS-Page. Methods: Plasma from 08 healthy young, 08 healthy elderly and 08 MDS patients were used for this study. Proteins were fractionated, precipitated, used for SDS-PAGE gel analysis, stained with comassie brilliant blue, scanned and bands were analyzed. Results: It was possible to identify in both, 20% fraction and supernatant, proteins that were differentially expressed in each group. The ones that have showed some clinical relevance. Fibronectin was highly expressed only in the young control group. α2-Macroglobulin was also expressed in both control groups, but it was not expressed in the MDS group. Haptoglobin was highly expressed only in the elderly control and SMD groups. Conclusion: Protein expression in plasma can be a biomarker for MDS, and may play a key role in the process of aging and hematologic malignancies development.

The motivational factors and adverse events experienced by healthy volunteers donating bone marrow for research

Published on: 5th December, 2019

OCLC Number/Unique Identifier: 8479094098

Background: With the advancement of cell therapy research, there is an increasing need for healthy volunteers (HV) to donate small volumes (30 ml) of human bone marrow (BM). The BM procedure required to procure small volumes is invasive, although short-lived (25 seconds), is not without risk. To ensure a sustainable supply of BM for research and cell therapy, greater information of the risks and factors that motivate HV to donate small volumes of BM will help optimize the procedure and HV enrolment, ensuring donors are fully informed of the potential risks. Objective: To identify the adverse events (AE) experienced by HV during and after small volume BM procedure and understand the motivating factors that influence HV to donate BM for research. Method: HV (n = 55) who donated BM (30 ml) for scientific research and provided informed consent were administered a questionnaire to identify the type, duration and severity of AE experienced during and post-BM aspiration; and to determine the motivating factors that influenced their willingness to donate BM. Results: Pain was experienced by 89% of participants during the BM procedure with moderate grade reported by 40%. One/more of the following AE were experienced by 73% of the volunteers post-BM procedure: pain, fatigue, site reaction, nausea and transient hypotension. AE resolved within an average of three days. The reported motivational factors ranked in the following order: first, to advance research for the benefit of future patients; compensation for participation; free medical check-up; lastly, the research question was interesting. Conclusion: Young HV, motivated primarily by altruism and financial compensation, risk the occurrence of transient AE following donation of small-volume BM for research.

Novel European Asiatic Clinical, Laboratory, Molecular and Pathobiological (2015-2020 CLMP) criteria for JAK2V617F trilinear polycythemia vera (PV), JAK2exon12 PV and JAK2V617F, CALR and MPL515 thrombocythemias: From Dameshek to Constantinescu-Vainchenker, Kralovics and Michiels

The Myeloproliferative Neoplasms (MPN) of trilinear polycythemia vera (PV) and megakaryocytic leukemia (ML = primary megakaryocytic granulocytic myeloproliferation: PMGM) and Essential Thrombocythemia (ET) in the studies of Dameshek and Michiels are caused by the MPN driver mutations JAK2V617F, JAK2exon12, CALR and MPL515 discovered by Constantinescu-Vainchenker, Green and Kralovics. The JAK2V617F mutated trilinear myeloproliferative neoplasms (MPN) include a broad spectrum of clinical laboratory and bone marrow features in essential thrombocythemia (ET), prodromal PV and erythrocythemic PV, classical PV and advanced stages of masked PV and PV complicated by splenomegaly and secondary myelofibrosis (MF). Heterozygous JAK2V617F mutated ET is associated with low JAK2 allele and MPN disease burden and normal life expectance. In combined heterozygous and homozygous or homozygous JAK2V617F mutated trilinear PV, the JAK2 mutation load increases from less than 50% in prodromal PV and classical PV to above 50% up to 100% in hypercellular PV, advanced PV and PV with MF. Bone marrow histology show diagnostic features of eryhrocytic, megakaryocytic and granulocytic (EMG) myeloproliferation in JAK2V617F mutated trilinear MPN, which clearly differs from monolinear megakaryocytic (M) myelproliferation in MPL and CALR thrombocythemia and dual megakaryocytic granulocytic (MG) myeloproliferation in CALR mutated thrombocythemia. The morphology of clustered large pleomorphic megakaryocytes with hyperlobulated nuclei are similar in JAK2V617F thrombocythemia, prodromal PV and classical PV patients. Monolinear megakaryocytic (M) myeloproliferation of large to giant megakaryocytes with hyperlobulated staghorn-like nuclei is the hallmark of MPL515 mutated normocellular thrombocythemia. CALR mutated thrombocythemia usually presents with high platelet count around 1000x109/l and normocellular megakaryocytic (M) proliferation of immature megakaryocytes with cloud-like hyperchromatic nuclei followed by dual megakaryocytic granulocytic (MG) myeloproliferation followed by various degrees of bone marrow fibrosis. Natural history and life expectancy of MPN patients are related to the response to treatment and the degree of anemia, splenomegaly, myelofibrosis and constitutional symptoms. The acquisition of epigenetic mutations at increasing age on top of MPN disease burden independently predict unfavorable outcome in JAK2V617F, MPL515 and CALR mutated myeloproliferative neoplasms (MPNs, which mutually exclude each other).

A Three approach at one stage to surgical management of Cervical Spondyloptosis after Failed Primary anterior fusion

Published on: 31st December, 2018

OCLC Number/Unique Identifier: 7970377562

A 35-year-old female, known case of complete spinal cord injury, presented with cervical pain and neck deformity that interfere with her physiotherapy and occupational therapy. Two years before admission, she had a car accident which result in a complete quadriplegia. That time at another center, she underwent surgery to anterior cervical fixation of C6-C7 through insertion of cage and plate without corpectomy. Based on current radiologic images, spondyloptosis was detected at the C6-C7 with bilateral locked facet, due to hardware failure. A three approaches in one stage was performed to maintain cervical alignment that includes posterior, anterior and again posterior approach. With this manner, anterior fusion through corpectomy and insertion of expandable cage and plate as same as instrumental posterolateral fusion were done. After surgery, she was pain free and the alignment of cervical spine was maintained so she could come back to ordinary rehabilitation programs.

Role of plants, environmental toxins and physical neurotoxicological factors in Amyotrophic lateral sclerosis, Alzheimer Disease and other Neurodegenerative Diseases

Published on: 4th March, 2019

OCLC Number/Unique Identifier: 8056301487

Aim of this work is to verify the effect of some neurotoxins, physical factors and geography in presentation of some Relevant Neurological disorder like some form of ASL, PD, AD. The geographic diffusion of the ASL/PD in west pacific (GUAM foci), and mutation of SOD 1 and other mutations are interesting facts to verify the recent literature about the neurotoxic process. Related to the references presented a global conclusion about the pathogenetic progression of some neurological disease will be produced as instrument for new hypothesis and for the introduction of new innovative therapeutic strategies.
