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.

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.

The forgotten player in the surgical history

Published on: 13th May, 2019

OCLC Number/Unique Identifier: 8164026356

The research concerning a preventive treatment of an osteoporitic femoral neck fracture started in 1990 because the surgical procedure of unstable femoral neck fractures is difficult. After effects are frequent and their number will increase in the next decade. The goal is to reinforce the femur with a biomaterial acting as a bone graft. Natural coral is bioresorbable and biocompatible. It acts as an autofocus bone graft for reconstruction of either cortex or cancellous bone and increases their mechanical resistance. This work shows evidence of new bone formation in an osteoporotic unbroken femoral neck femur. Consequently, the preventive surgical treatment of osteoporosis should be taken in consideration [1]. The purpose of this work is to show the results on the mineralization of the cancellous bone of an upper femoral metaphyses when a natural biomaterial is set in an unbroken osteoporotic femoral neck. Summary: Mrs. L is an 84 years old lady. Her osteoporotic unbroken right hip was grafted preventively with a biomaterial in order to prevent the high risk of break in case of fall. The biomaterial used is beads of natural coral. The reasons of this preventive treatment is discussed, as well as the choice of the biomaterial. The results are shown including a two years follow up. Brief History: Before going further, few words of history. Three centuries BC, an Aristote’s follower, Théophraste thinks that Natural coral is a petrified plant. For Ovide natural coral is a soft alga air-hardening. Al Biruni classes it among animals, because that respond to touch. At the beginning of the XVIIth century, Marsigli thinks that they are flowers which open out there in aquarium. The French Jean-André Peyssonnel, a young naturalist, says as Biruni, that in fact, corals are animals. At last, Buffon claims: These marine plants, were classified first in the rank of minerals, then in those of plants, and finally in that of animals. Natural coral is obviously an animal. After the Second World War, coral samples were analyzed by American scientists. Among 800 corail species, 3 where specially analyzed: Acropora, Porites and Libophylia. Mrs Nane Guillemin did in France her PHD on natural coral and with her team made a complete fundamental analysis (physical, chemical and biological properties) of the material, while the American scientists worked on the chemical bone’s properties. In France, Pr Ohayoun and his team worked on the surgical application in the dental field, Dr. Yves Cirotteau in the orthopedic surgery, specifically for osteoporotic disease and for the traumatologic field

Vigour of CRISPR/Cas9 Gene Editing in Alzheimer’s Disease

Published on: 5th October, 2018

Ailment repairing regiments has turn out to be arduous, despite a plenty of understanding and knowledge acquired in the past relating to the molecular underpinnings of Alzheimer’s disease (AD. Umpteen clinical experiments targeting the fabrication and accumulation have been turned fruitless to fit potency standards. The tests aiming beta-amyloid hypothesis also turned futile making it exigent for further handling tactics. The new emanation of a comparably candid, economical, and punctilious system known as gene editing have showed light in path of cure for AD by CRISPR/Cas9 gene editing. Being a straight approach this procedure has already shown assurance in other neurological disorders too such as Huntington’s disease. This review standpoint the immanent service of CRISPR/Cas9 as a remedial option for AD by aiming on specific genes inclusive of those that induce early-onset AD, as well as those that are substantial risk components for late-onset AD such as the apolipoprotein E4 (APOE4) gene.

Serum MicroRNA-155 in Acute Graft-Versus-Host-Disease (aGVHD)

Published on: 16th August, 2019

OCLC Number/Unique Identifier: 9059393117

Allogeneic hematopoietic stem cell transplant (alloHSCT) is a curative treatment for many hematologic malignancies. Unfortunately, about 30-50% of all recipients undergoing alloHSCT develop acute graft-versus-host-disease (aGVHD), which is associated with high morbidity and mortality [1,2]. Treatment of aGVHD involves the use of immune suppressive drugs such as high dose of steroids that leads to further immunosuppression and risk for opportunistic infections. Often patients are refractory to steroids therapy making the prognosis dismal. Thus, it is critical to identify robust biomarkers to detect aGVHD before onset of clinical symptoms so that therapeutic strategies can be implemented that may result in better treatment responses and less toxicity.

Drug abuse and its ramifications on skeletal system

Published on: 5th November, 2019

OCLC Number/Unique Identifier: 8330461480

The purpose of this study is to highlight the drug abuse hazards and preventive aspects. From a public health perspective, substance abuse has long been a source of major concern, both for the individual’s health and for wider society as a whole. The UK has the highest rates of recorded illegal drug misuse in the western world. In particular, it has comparatively high rates of heroin and crack cocaine use. Substances that are considered harmful are strictly regulated according to a classification system that takes into account the harms and risks of taking each drug. The adverse effects of drug abuse can be thought of in three parts that together determine the overall harm in taking it. Some addictive substances are more damaging to the skeletal system along with the others. In this review article, an effort has been taken to elaborate the effects of addictive drugs on human highlighting these most problematic substances for bones and also the promising potential prevention aspects of drug abuse.

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.

Comparative study of carboxylate and amide forms of HLDF-6 peptide: Neuroprotective and nootropic effects in animal models of ischemic stroke

Published on: 24th July, 2019

OCLC Number/Unique Identifier: 8195621281

Aim:The work was to perform a comparative study of the neuroprotective and nootropic activities of two pharmaceutical substances, the HLDF-6 peptide and its amide form (HLDF-6-NH2). Materials and Methods: We used in the study healthy adult male Wistar rats aged 180–200 days weighing 280–300 g. We modelled ischemic stroke in rats by chronical occlusion of carotid arteries. Solutions of the HLDF-6-NH2 and HLDF-6 peptides were administered intranasally. Cognitive functions we assessed with Novel object recognition test and Morris maze. Results: The amide form of HLDF-6 peptide is more efficient: the neuroprotective activity of HLDF-6-NH2, evaluated by improvement of cognitive functions in animals, surpassed that of the native HLDF-6 peptide. A dose of 250 µg/kg of HLDF-6-NH2 peptide resulted in practically complete restoration of the disturbed functions. In the model of ischemic stroke, the amide form of the peptide significantly excelled the reference substance mexidol both in the effective dose and biological activity. Conclusion: The results of study of the agent allow hoping for its success in further clinical investigation. In view of high demand for the agent and in case of successful clinical trials, it will surely become widely used in clinical practice in treatment of IS.

Gastrointestinal stromal tumor resulting in recurrent colic in a arabian horse gelding a report of case

Published on: 2nd November, 2020

OCLC Number/Unique Identifier: 8697203989

Background: A Grey 12-year-old Arabian endurance horse gelding was referred to the SHS Veterinary Center for anorexia, mild colic of 5 days duration, and melena of 1 day duration. The owner reported recurring colic, 12 episodes of mild colic in the previous year. Methods: On admission, vital signs were within normal limits and body condition score was estimated to be 3/9. Results: Packed cell volume (PCV) was 28% [reference range (RR): 31% to 47%] and plasma total protein was 58 g/L (RR: 60 to 80 g/L). Hematochezia was observed. Abdominal ultrasound examination detected no abnormalities. Over the next 12 h, the horse experienced hematochezia and several mild episodes of colic and death. A necropsy was performed. A mass arising from the right dorsal ascending colon near the base of the cecum and extending transmurally from the colonic mucosa into the mesocolon was a 8 cm × 5 cm × 8 cm firm, homogenous, tan mass. The portion of the mass that extended into the colonic lumen was pedunculated, with an ulcerated surface. The adjacent segments of colon were markedly reddened and edematous. Histologically, the mass was comprised of large interweaving sheets of small, spindle cells with ill-defined cell borders embedded in abundant myxomatous matrix. Tumor cells contained scant eosinophilic cytoplasm and oval to elongate nuclei with finely stippled chromatin and inconspicuous nucleoli. Mitotic figures were rare (1/10) high power fields. Tumor infiltrated between the muscularis interna and the muscularis externa at the myenteric plexi. Conclusion: Gross and histologic appearance, were consistent with a diagnosis of gastrointestinal stromal tumor.

Characterization of Salmonella spp. isolated from small turtles and human in Republic of Korea

Published on: 11th December, 2020

OCLC Number/Unique Identifier: 8873196747

In 2013, the World Health Organization (WHO) reported that small, pet turtles had caused multistate Salmonella outbreaks in the United States, from where small turtles were subsequently exported into the Republic of Korea. We investigated cases of salmonellosis in South Korea associated with domestic small turtles and analysed genetic characteristics of Salmonella isolates in commercially-available small turtles. We traced six Salmonella serovars, known to have caused human infection in the United States (S. Sandiego, S. Pomona, S. Poona, S. Newport, I 4,(5),12:i:-, and S. Typhimurium), in isolates from suspected Salmonella infection cases in Korea from 2006 to 2015. Additionally, we conducted a pilot study of isolates from small turtles being sold in Korean markets, and performed molecular genetic analysis on the identified strains. S. Pomona was identified in one Salmonella infection case, while all strains isolated from small turtles belonged to either subspecies I (enterica, n = 10, 71.4%) or subspecies IIIb (diarizonae, n = 4, 28.6%). Two serovars (S. Pomona and S. Sandiego) that were highly associated with turtle-to-human transmission were identified with 100% homology to human isolates. Previous to this study, turtle-associated human S. Pomona infections were not well reported in Korea. We report Salmonella infection in small turtles in Korea, and confirm that small turtles should be considered the first infectious agent in S. Pomona infection. We therefore suggest quarantine measures for importing small turtles be enhanced in Korea.

Tamsulosin and Dementia in old age: Is there any relationship?

Published on: 1st October, 2019

OCLC Number/Unique Identifier: 8280929913

Tamsulosin is used to treat Benign Prostatic Hyperplasia (BPH), prescribed annually to about 12.6 million patients worldwide. It is an alpha-adrenergic antagonist that reduces the tone of the prostate smooth muscle involved in the pathophysiology of BPH. By acting on alpha 1A receptors, predominant in the prostate, tamsulosin also acts on receptors present in the brain. This study consisted of a literature review aimed at disseminating scientific knowledge about the relationship between the use of tamsulosin and the onset of dementia. PubMed, Scopus, Scielo, Embase, and Web of Science studies involving dementia in patients using tamsulosin in the last five years were selected. The review showed a risk correlation and a higher incidence of dementia in treated patients. The risk ratio, when compared to other medicines, approached 1.20. In conclusion, it was identified the need for clinical trials with higher sampling power to increase relational significance due to the high prevalence of BPH and the extensive use of tamsulosin in elderly patients with the disease.

Protection from the Pathogenesis of Neurodegenerative Disorders, including Alzheimer’s Disease, Amyotrophic Lateral Sclerosis, Huntington’s Disease, and Parkinson’s Diseases, through the Mitigation of Reactive Oxygen Species

Published on: 4th November, 2019

OCLC Number/Unique Identifier: 8302209826

The biological changes caused by oxidative stress (OS) are known to be involved in the etiology of neurodegenerative disorders, including Alzheimer’s disease, amyotrophic lateral sclerosis, Huntington’s disease, and Parkinson’s disease. The brain is particularly vulnerable to OS due to its high lipid content and extensive consumption of oxygen. OS processes, particularly the excessive production of reactive oxygen species (ROS), play a critical role in how neurodegenerative disorders develop. This is evidenced by in vivo studies investigating various biomolecules related to OS, such as products of lipid and DNA oxidation. Accordingly, ROS can also cause oxidative-related damage in neurodegenerative disorders, including dopamine auto-oxidation, mitochondrial dysfunction, glial cell activation, α-synuclein aggregation, excessive free iron, and changes in calcium signaling. Furthermore, excessive levels of cellular oxidants reduce antioxidant defenses, which in turn propagate the cycle of OS. As such, it is increasingly important to determine the linkage between a high intake of antioxidants through dietary interventions and a lower risk of developing neurodegenerative diseases. Indeed, in addition to modulating the immune system, optimal nutritional status is capable of changing various processes of neuroinflammation known to be involved in the pathogenesis of neurodegeneration. Accordingly, a better understanding of the role ROS plays in the etiology of neurodegeneration is needed, along with the identification of dietary interventions that may lead to improved therapeutic strategies for both the treatment and prevention of neurodegenerative disorders. Therefore, this review presents a comprehensive summary of the role of ROS in the pathogenesis of neurodegenerative disorders. In addition, nutrients believed to be useful for mitigating and counteracting ROS are discussed.

Immunohistochemical expression of Nestin as Cancer Stem Cell Marker in gliomas

Published on: 11th November, 2019

OCLC Number/Unique Identifier: 8457474432

Background: Gliomas represent the most frequent primary tumors of central nervous system (CNS), contributing to more than half of the incidence of brain tumors. Cancer stem cell markers (CSC) identify a group of patients at high risk for progression. Nestin is an intermediate filament (IF) protein was first described as a neural stem cell/progenitor cell marker. Nestin-positive neuroepithelial stem cells are detected in the subventricular zone of the human adult brain and they remain mitotically active throughout adulthood. The expression of Nestin in gliomas has been suggested to be related to dedifferentiation, improved cell motility, invasive potential and increased malignancy. This study aims to investigate Nestin immunohistochemical expression in different types of glioma and its correlation with different clinicopathological parameters. Materials and Methods: Nestin immunostaining was studied in 60 specimens of glioma using avidin-biotin peroxidase method. Results: Nestin was strongly expressed in 11/60 (18.33%), moderately expressed in 29/60 (48.33%) and weekly expressed in 15/60 (25%) of studied gliomas. A significant positive correlation was found between Nestin expression and histologic type (p < 0.001) and increasing grade of gliomas (p < 0.001). Conclusion: Increased Nestin expression is correlated with tumor progression, increasing grade and poor prognostic parameter of glioma. Nestin is a useful marker for detection of CSC in high-grade glioma which is responsible for resistance to chemo-radiotherapy and may serve as a predictor for patient outcomes.

Obesity may increase the prevalence of Parkinson’s Disease (PD) while PD may reduce obesity index in patients

Published on: 6th April, 2020

OCLC Number/Unique Identifier: 8589557020

Objective: Currently, Parkinson’s disease (PD) is becoming more common among younger people of ages from 30 – 40 years. The incidence is higher among patients with higher body mass index (BMI), and some reports had it that Obesity is a risk factor for PD while some reported that there is no relationship between obesity and PD. PD patient at the time of diagnosis has an above-normal BMI but which goes below normal as the disease progresses. Therefore, it is essential to explore the relationship between PD and Obesity. Methods: 349 outpatients and inpatients with PD were selected from Jiangsu University Affiliated People’s Hospital from January 2014 to December 2018, while 74 inpatients with non-cerebrovascular illness in the same period were selected as the control group. According to Hoehn-Yahr grade, Parkinson’s patients were divided into three groups. The height, weight, waist and hip circumference, total cholesterol (TC), Total Glycerol (TG), high-density lipoprotein cholesterol (HDL-C) and low-density lipoprotein cholesterol (LDL-C) were measured and recorded. The relationship between the severity of Parkinson’s disease and blood lipids was evaluated. Results: The BMI of patients with PD in the early stage was higher than that of the control group, but lower than that of the control group in the late stage, and the level of blood lipid in the patients with early PD was significantly higher than that in the control group and patients with advanced PD, especially in TG. The waist circumference and hip circumference of the patients with early PD were higher than those in the control group, but there was no statistical difference. Conclusion: i) Obesity may increase the prevalence of PD. ii) The BMI of patients with PD shows two-way changes in different periods. iii) The BMI is higher and cholesterol is more elevated in the early stage of patients with PD, while at the advanced stage of the disease, the BMI and lipid levels of the patients showed a downward trend, which may be associated with a metabolic syndrome associated with dopamine depletion.

Comparison of resting-state functional and effective connectivity between default mode network and memory encoding related areas

Published on: 24th April, 2020

OCLC Number/Unique Identifier: 8589567444

Currently brain connectivity modelling, constructed from data acquired by non-invasive technique such as functional magnetic resonance imaging (fMRI), is a well-received approach to illustrate brain function. However, not all connectivity models contains equal amount of information. There are two types of connectivity model that could be constructed from fMRI data, functional and effective connectivity. Effective connectivity includes information about the direction of the connection, while functional connectivity does not. This makes interpretation of effective connectivity more meaningful than functional connectivity. The objective of this study is to show the improvement in interpretability of effective connectivity model in comparison to functional connectivity model. In this study, we show how the difference in the information contained within these two model impacts the interpretation of the resulting connectivity model by analyzing resting-state fMRI data on episodic memory-related cognitive function using CONN Toolbox bivariate correlation measurement for functional connectivity analysis and Tigramite causal discovery framework for effective connectivity analysis on an episodic memory related resting-state fMRI dataset. The comparison between functional and effective connectivity results show that effective connectivity contains more information than the functional connectivity, and the difference in the information contained within these two types of model could significantly impact the intepretation of true brain function. In conclusion, we show that for the connectivity between specific pair of brain regions, effective connectivity analysis reveals more informative characteristic of the connectivity in comparison to functional connectivity where the depicted connectivity lack any additional characteristic information such as the direction of the connection or whether it is a unidirectional or bidirectional. These additional information improve interpretability of brain connectivity study. Thus, we would like to emphasis the important of brain function study using effective connectivity modelling to obtain valid interpretation of true brain function as currently a large body of research in this field focuses only on functional connectivity model.

Role of yoga in Parkinson’s disease-A comprehensive update of the literature

Published on: 26th May, 2020

OCLC Number/Unique Identifier: 8605987262

Parkinson’s disease (PD) is a neurodegenerative disorder characterized by progressive degenerative motor symptoms (e.g., tremors, impaired balance and gait) and nonmotor symptoms (e.g., fatigue, sleep disturbances, pain) that can negatively influence health and mental wellbeing by decreasing quality of life. It affects nearly 10 million people and more and more cases are diagnosed because of the advancement seen in movement disorder clinics and diagnostic tools worldwide. Individuals with PD also complain about anxiety arising out of these symptoms of postural instability, low back pain etc., which may lead to increased risk of falls and fall related injuries of brain, bone or other organ systems. Stress is one factor which has been shown to directly correlate to neurodegenerative pathology. Ways to reduce stress at a given point of time and across one’s life span is considered to be a prime necessity in today’s world. Various body-mind exercises like yoga, tai chi, qi gong, tango, ballet etc., has been in research for quite some time now, which has shown benefits in PD patients. In this article evidences related to yoga and its role in PD will be reviewed in a detailed fashion.

Atlantoaxial subluxation in the pediatric patient: Case series and literature review

Published on: 26th November, 2020

OCLC Number/Unique Identifier: 8799428362

Objective: Atlantoaxial subluxation (AAS) occurs when there is misalignment of the atlantoaxial joint. Several etiologies confer increased risk of AAS in children, including neck trauma, inflammation, infection, or inherent ligamentous laxity of the cervical spine. Methods: A single-center, retrospective case review was performed. Thirty-four patients with an ICD-10 diagnosis of S13.1 were identified. Demographics and clinical data were reviewed for etiology, imaging techniques, treatment, and clinical outcome. Results: Out of thirty-four patients, twenty-two suffered cervical spine trauma, seven presented with Grisel’s Syndrome, four presented with ligamentous laxity, and one had an unrecognizable etiology. Most diagnoses of cervical spine subluxation and/or instability were detected on computerized tomography (CT), while radiography and magnetic resonance imaging (MRI) were largely performed for follow-up monitoring. Six patients underwent cervical spine fusion, five had halo traction, twelve wore a hard and/or soft collar without having surgery or halo traction, and eight were referred to physical therapy without other interventions. Conclusion: Pediatric patients with atlantoaxial subluxation may benefit from limited 3D CT scans of the upper cervical spine for accurate diagnosis. Conservative treatment with hard cervical collar and immobilization after reduction may be attempted, but halo traction and halo vest immobilization may be necessary. If non-operative treatment fails, cervical spine internal reduction and fixation may be necessary to maintain normal C1-C2 alignment.

Perceived causes and prevention of catheter-associated urinary tract infections among spinal cord injured patients

Published on: 27th November, 2019

OCLC Number/Unique Identifier: 9272371774

Catheter-associated urinary tract infection (CAUTI) is among the most common nosocomial infections especially in acute care settings. Its economic and unanticipated health implications make it burdensome for the healthcare providers and patients. The paper examined the perceived causes and mode of preventing urinary tract infections in patients with spinal cord injury. Qualitative research approach was utilized; the study site was a Tertiary Hospital in Nigeria. Eight (8) in-depth interviews (IDI) were conducted with healthcare providers managing patients with spinal cord injured in the hospital. The major risk factors causing urinary tract infection identified include financial problems, organization of care, human error, hospital environment and patient-related factors. To prevent urinary tract infections among patients in the hospital, a number of suggestions were made by the participants such as training of caregivers and educating patients and relations. The authors concluded that the incidence of CAUTI could be reduced in the hospital if the opinions of stakeholders are fairly considered.

SGLT2 Inhibitors and nephroprotection in diabetic kidney disease: From mechanisms of action to the latest evidence in the literature

Published on: 21st August, 2020

OCLC Number/Unique Identifier: 8651234199

Type 2 Diabetes Mellitus constitutes a major problem in public health worldwide. The disease poses a high risk of severe microvascular and macrovascular complications. Diabetic kidney disease is the most common cause of end-stage chronic kidney disease and contributes to the increasing morbidity and mortality associated to diabetes. Sodium-glucose contransporter-2 inhibitors (SGLT2 inhibitors) are the latest oral diabetic medications, which exhibit a great nephroprotective potential, not only by improving glycemic control, but also by glucose-independent mechanisms, such as decreasing blood pressure and other direct renal effects. We conduct a literature review based on the most recent scientific evidence with the goal to elucidate the postulated mechanisms of action of SGLT2 inhibitors in diabetic kidney disease, which are the base of the beneficial clinical effects that are seen in the condition.

Acute kidney injury in Colombian patients with COVID-19 who received kidney support therapy with genius® 90 technology

Published on: 11th September, 2020

OCLC Number/Unique Identifier: 8665847570

Introduction: Acute kidney injury (AKI) is one of the complications associated with severe COVID-19 infection, and it can present in up to 20% to 40% of the cases; of these, approximately 20% will require renal replacement therapy (RRT). Objective: To establish clinical and laboratory characteristics in a group of patients from Colombia with COVID-19 infection and AKI that received intermittent and prolonged RRT with the GENIUS® 90 technology in between March and July 2020. Design: Cross-sectional study. Results: 78.9% of participants were men and 21.1% were women. The main comorbidities were the following: Hypertension (65.3%), diabetes mellitus (38.9%), obesity (26.3%), cancer (5.3%), Chronic obstructive pulmonary disease (11.6%), cardiovascular disease (23.2%), active smoking (11.6%). 33.7% had chronic kidney disease (CKD) in the average serum creatinine on admission was 4.4 mg/dl. The following inflammatory markers were elevated: C-reactive protein (CRP), d-dimer and ferritin (20.3 mg/dl, 931mcg/l and 1174 ng/ml, respectively). 63.5% of patients underwent sustained low-efficiency dialysis (SLED) (6 to 12 hours) and the rest of the patients (36.35%) underwent conventional hemodialysis (less than 4 hours). The mortality of the total patient sample was 36.9%, lower in patients with CKD than in patients with no previous renal disease history (18.7% and 40.1%, respectively). Conclusion: Renal complications are frequent in patients with severe COVID-19. The development of AKI could be an isolated prognostic marker associated with an increase in mortality in patients with COVID-19, and one of the options is intermittent and prolonged RRT with the GENIUS® 90 system.
