Objective To study morphological and radiological parameters of facet joints depending on the grade of the intervertebral disk degeneration. Materials and methods To study the facet joints of the lumbar spine in 145 patients with various grades of degeneration according to Pfirrmann and treated using rigid fixation and TLIF technology, MSCT in 2-energy mode and morphological investigation of the intraoperative material were performed. Results In Pfirrmann grade 2, an increase in the volumetric content of chondrocytes, Hounsfield density of the cartilage plate, and the level of Ca in the facet joints was visualized. They indicate that the joint remains functional. In Pfirrmann grade 5, deep pathological changes occurred with violation of the architectonics of the cartilage formations of the facet joints, formation of bone elements and connective tissue growth into the cartilage and bone structures of the joint, which correlated with the results of MSCT. Conclusion The data obtained show that there is a close relationship between morphological and radiological changes in the facet joints. Modulating the data obtained allows us to obtain objective criteria for evaluating the grade of pathological processes in facet joints and use them as a diagnostic component when planning decompression and stabilizing operations in patients with degenerative diseases of the lumbar spine.

Introduction This article describes a clinical case of a stress fracture of the distal tibial metaepiphysis following a high-energy tibial shaft fracture stabilized with interlocking intramedullary (IM) nail to identify an underlying cause of the traumatic event. Objective To demonstrate the occurrence of a stress fracture after adequate interlocking IM nailing of a traumatic fracture due to systemic osteoporosis that presented no clinical manifestations prior to injury. Material and methods Magnetic resonance imaging was performed to diagnose the stress fracture. Bone mineral density and laboratory markers of bone metabolism were measured to identify underlying causes of the stress fracture. Consolidation of the traumatic fracture fixed with interlocking IM nail was re-evaluated with a radiograph of the fracture site. Results The stress fracture was seen off the IM nail on MRI scans. Osteoporosis was diagnosed with bone densitometry using dual energy X-ray absorptiometry, and deoxypyridinoline, a bone resorption marker and vitamin D deficiency were identified with laboratory tests. No signs of fracture union were seen radiologically. Conclusion A stress fracture of the distal tibial metaepiphysis detected 3 months after a tibial shaft fracture fixed with interlocking IM nail can be considered an insufficiency fracture caused by primary (idiopathic) systemic osteoporosis that was asymptomatic prior to the high-energy injury.

Objective Review emerging trends within healthcare sectors internationally to care for spinal conditions in developed Western European and North American countries. Material and methods An explorative review of electronic bibliographic (Scopus, Pubmed, etc.), thesis and dissertation database, organization websites, grey literature resources and reference lists of relevant papers was undertaken to identify the key publication outlets for relevant content between 2016 to 2020. In the present review, the depth of the search was 27 years (post 1994). This review utilized a methodology structured using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA-ScR and PRISMA-S preprint) checklist with the description available on https://doi. org/10.17605/OSF.IO/5JGN4. Results The researchers explored the conditions for strong primary spine care providing effective measures and strategies in streamlining patients and examined the appropriateness of referrals for high-technology imaging assessment. Primary care with its integrative function is provided by professionals with specialized training including general practitioners and nurses. Guidance on the management and standards of inpatient care for a diverse and complex range of conditions are of concern with a focus on specialized spinal services providing invasive management strategies for traumatic spinal cord injuries, in particular. Direct access to diagnostic procedures is essential at specialised spinal services providing conservative and surgical management for a acute spinal diseases with the decision making process and care for this group of patients being very complex with little support of evidence based medicine sources. Conclusion Significant input from clinical and support services is required to provide clinical practice guidelines based upon the best available research evidence and practice experience with a greater range of approaches and techniques.
Clinical correlation of glaucoma with systemic hypertension and its effect on visual morbidity
Authors: Anamalai Radha , Priyadharshini P , Muthayya M
Published: December 2020

Glaucoma and hypertension share a common pathophysiology of altered sodium transport in the renal and ciliary epithelium and can co exist. High blood pressure is a significant risk factor for glaucoma progression due to intraocular pressure spikes.

This study was performed to evaluate the association of hypertension with glaucoma and to assess the extent of optic disc damage, the role of anti hypertensive medications and visual morbidity.

This is a prospective, multidisciplinary study performed on a cohort of118 hypertensive patients over 1 year. Ophthalmic examination, ancillary ocular investigations, systemic tests and multi speciality referrals were obtained for all patients.

Among 118 hypertensive patients, 64 (54.8%) had glaucoma. 65 patients (55.1%) were female and 53 patients (44.1%) male. Age group most frequently affected was between 60 and 70 years. There was increased incidence of ocular hypertension which was statistically significant (p value of 0.02). The range of IOP in those on anti hypertensive medications was 10-16 mmHg which was statistically significant (p value = 0. 03).

Risk of glaucoma in hypertension was higher in women. An elevation of diastolic blood pressure is more significant than systolic BP in raising IOP. Decreased IOP was highest among patients taking calcium channel blockers.

: Hypertension can cause both reduction and elevation in IOP. Treatment of hypertension does lower the IOP and prevent further progression of glaucoma and prevent any visual loss.

To study the prevalence of dry eye in a hospital-based population and to study the tear film parameters in dry eye patients presenting with symptoms of grittiness and foreign body sensation attending the ophthalmology outpatient department of Karpaga Vinayaka Institute of Medical Sciences, Chengalpattu, Tamil Nadu.

Cross Sectional study conducted in the out patient department of our department among patients presenting with symptoms suggestive of dry eyes both male and female patients consenting to the study were included.

A total of 125 participants were enrolled, of these 38 had dry eye, 67 had long duration of work. 86 patients had complaints suggestive of dry eye. 38 had all 3 parameters tested abnormal. Tear film was evaluated with Schirmer test, TBUT, TMH and a proforma to record patient demographic details, symptoms, test values and dry eye diagnosis.

our study showed 86 participants with symptoms such as grittiness, foreign body sensation, dryness, burning sensation and 38 patients had dry eye and required treatment such as lubricants. Poor quality and function of tears, combined with subnormal ocular surface, makes patients symptomatic and on evaluation show ocular surface disease dry eye which can be treated accordingly to relieve the patient of symptoms and improve the quality of life. Thus routine and early examination of tear function and ocular surface parameters should form a part of the workup of all patients with symptoms of dry eye.

Authors: Mirmosayyeb Omid , Barzegar Mahdi , Nehzat Nasim , Najdaghi Soroush , Ansari Behnaz , Shaygannejad Vahid
Published: December 2020

Background: Multiple sclerosis (MS) is a common autoimmune inflammatory disease in the central nervous system (CNS) without exact pathology. Environmental factors such as infections have a causal or protective role in MS. Helicobacter pylori (HP) is one of the infections in digestive diseases and previous studies reported controversial findings of this infection role in MS. So, we conducted this study to assess the frequency of HP infection in patients with MS in comparison to the healthy population.
Methods: This cross-sectional study was undertaken between 2015 and 2019. 191 participants including 58 patients with clinically isolated syndrome (CIS), 57 patients with relapsing-remitting MS (RRMS), 39 patients with secondary progressive MS (SPMS), and 39 age- and sex-matched healthy controls (HCs) were tested for the presence of HP immunoglobulin G (IgG) and IgM antibodies (Abs) in their serum sample.
Results: The frequency of HP IgG seropositivity in patients with SPMS was significantly higher than patients with CIS [Odds ratio (OR): 6.333, 95% confidence interval (CI): 2.522-15.906, P < 0.001], patients with RRMS (OR: 4.583, 95% CI: 1.842-11.407,  P = 0.001), and HCs (OR: 8.485, 95% CI: 3.058-23.540,  P < 0.001). We did not find a significant difference among other study groups regarding IgG seropositivity. No significant difference among groups regarding HP IgM seropositivity was evident. On univariate model, Expanded Disability Status Scale (EDSS) score (OR: 1.038, 95% CI: 1.038-1.460, P = 0.017) and SPMS (OR: 4.583, 95% CI: 1.842-11.407, P = 0.001) were predictor for HP IgG seropositivity. On multivariate model, only SPMS had higher risk for HP IgG seropositivity compared to RRMS (OR: 5.554, 95% CI: 1.327-23.253, P = 0.019). We did not find a significant association between clinical and demographic variables with HP IgM seropositivity.
Conclusion: Based on our findings, progressive MS and HP infection may have association. Further longitudinal studies with large sample size are needed to determine the role of HP infection in MS.

Published: December 2020

Background: Migraine is a neurologic disorder. Although, based on previous evidence, migraine is related with inflammation and oxidative stress, its relationship with the inflammatory potential of the diet is still unknown. Thus, the aim of this study was to show the correlation between Dietary Inflammatory Index (DII) and severity and duration of migraine headache.
Methods: In this cross-sectional study, 266 women who suffered from migraine, were included. Demographic and anthropometric data were collected form all participants. 147-item semiquantitative food frequency questionnaire (FFQ) was collected to assess dietary intake and consequently, DII scores were calculated. Migraine Disability Assessment (MIDAS) questionnaire, Visual Analog Scale (VAS), and a 30-day headache diary were also completed by each participant.
Results: The DII score ranged between -4.22 and 5.19 and its median [interquartile range (IQR)] was 0.003  (-1.48-1.55). There was no meaningful association between age, occupation, physical activity (PA), weight, height, Body Mass Index (BMI), waist circumference (WC), hip circumference, waist-to-hip ratio (WHR) and DII score classifications (P > 0.050). Subjects with more than 20 days of headache had higher DII score compared to those with less than 10 days per month [odds ratio (OR) = 1.60, 95% confidence interval (CI) = 1.12-2.08, P = 0.001]. There was no association between DII and migraine severity (VAS and MIDAS) in the crude and adjusted model of logistic regression. Although there was a significant association between headache duration and DII  (P = 0.020), this relationship was not meaningful after adjusting for age, PA, BMI, and job status (OR = 0.53, 95% CI = 0.28-1.00, P = 0.052).
Conclusion: The present study showed a direct association between headache frequency and DII. Nevertheless, any relationship was not found between headache duration or migraine severity and DII score. Future large and prospective studies are needed to explore the effect of inflammatory potential of diet in migraine characteristics.

Published: December 2020

The problem of studying the problems of improving legal mechanisms for protecting public health and supporting business in the context of the COVID-19 coronavirus pandemic is very relevant. The pandemic has raised questions for several governments not only about the effectiveness of the health system, but also about the performance of the entire public administration system. Some aspects of possible legislation reform in the field of public protection and business support in emergency situations caused by the spread of dangerous infectious diseases are investigated. The article summarizes and analyzes the main provisions of the documents regulating the introduction of restrictive measures for the population during the coronavirus pandemic. It is shown that in the conditions of a pandemic, the population and small and medium-sized businesses could expect to be compensated for part of the damage on the basis of the decree of the Government of the Russian Federation No. 1928 of December 28, 2019 on the rules of transfer in emergency situations. The authors believe that in reality, when an emergency situation was introduced in Russia, the victims could be automatically provided with minimal payments and transfers. The authors of the article showed that the pandemic has increased society's dependence on digital technologies. The authors reviewed the experience of France, where the government has taken several large-scale and immediate support measures to help overcome the difficulties for small and medium-sized businesses that are most affected by the pandemic. The article is aimed at developing legal mechanisms to mitigate the threat to the population and business consequences of possible global disasters.

Published: December 2020

Personal data has become an important type of information for Chinese society. The risks and problems of protecting personal data have increased due to the rapid build-up of information. The protection of personal data is not only a sphere of private law, but also part of administrative law in cases where administrative authorities collect, process and use personal data. Administrative legislation is developing rapidly. However, the administrative and legal protection of personal data has even some legal basis, but still faces many difficulties in its implementation. In this regard, it is necessary to establish a special law on the protection of personal data, form a mechanism for strict supervision and improve the legal protection system.

El rol de los sistemas de control en el desarrollo de la confianza organizacional
Authors: Farías Landabur Antonio
Published: December 2020

Distintos autores sostienen la idea de que la mera presencia de sistemas de control en una organización genera desconfianza entre sus miembros. En la práctica, sin embargo, es posible observar distintas organizaciones donde operan sistemas de control y, al mismo tiempo, existe un elevado nivel de confianza organizacional.A partir de una investigación bibliográfica, el presente estudio postula que esta aparente contradicción puede ser superada si se toma en consideración el posible rol que desempeñan los sistemas de control cuando se aplican en las distintas etapas del proceso de desarrollo de la confianza. Más específicamente, el estudio postula que, en la primera etapa de la relación entre un líder y sus colaboradores, el líder debe aplicar el control haciendo un uso más intenso del control sobre el comportamiento; en la segunda etapa, utilizando de manera más intensa el control por resultados; y en la tercera etapa, haciendo un uso más intensivo del control cultural.
Apuntes para un esbozo del valor de la tragedia para el akratḗs
Authors: Román Molero Massiel
Published: December 2020

En el pasaje 1147b6-9 de la Ética Nicomáquea, Aristóteles subraya que el akratḗs es capaz de arrepentimiento sin indicar cómo, pues ello debe ser escuchado de los fisiólogos. Este trabajo, no obstante, sostiene que Aristóteles no deja este problema sin respuesta: dado que la educación es el marco en el que el hombre se ejercita, a lo largo de su vida, en el buen vivir, la construcción de la acción trágica en la Poética puede verse como una herramienta pedagógica que permite una profundización en el conflicto entre la razón y las pasiones del akratḗs, y cuyo genuino aporte estriba en su capacidad de explotar sus páthē para él y encauzarlas hacia una reflexión, a través de un ejercicio deductivo, sobre su propia condición.
Crecimiento postraumático, rumiación y estrategias de afrontamiento en niños, niñas y adolescentes expuestos al terremoto de Coquimbo de 2015
Authors: Andrades Mariela , García Felipe E.
Published: December 2020

El objetivo del presente estudio fue identificar las estrategias de afrontamiento y estilos rumiativos que se relacionan con Crecimiento Postraumático (CPT), en una muestra de 105 participantes de 12 a 16 años, encuestados 12 meses después del terremoto del año 2015 en la ciudad de Coquimbo, Chile. Los resultados muestran que la rumiación deliberada y las estrategias de afrontamiento productivas predijeron significativamente el CPT. Además, se observó que cuando los participantes sienten amenazas importantes a su integridad, aumentan sus niveles de CPT. Estos resultados permitirían diseñar estrategias de intervención que ayuden a enfrentar las consecuencias de un desastre natural en niños, niñas y adolescentes.

Published: December 2020

The aim of the study is to develop and substantiate the method of recreational activities of adolescents with I-II degree obesity. We assumed that the technique we developed will contribute to reducing this pathology and, in turn, reducing the occurrence of diseases of the cardiovascular, respiratory, digestive and urinary systems. We presented the results of investigation of influence of the proposed technique on morphofunctional state of adolescents with obesity of I-II degree. The entire range of recreational activities consisted of three stages and was complex. The first stage of the technique included general development, health-corrective exercises, which were performed in alternation with respiratory exercises. In the second stage, cyclical exercises were used, and the third stage of the technique included exercises aimed at reducing the fat component, which led to normalization of body weight. Relaxation exercises were used as restorative. Special attention in the methodology we proposed we gave to the sequence of increasing the load and its control during physical exercises, as well as taking into account the degree of obesity of a teenager. We used anthropometry, caliperometry, and body mass index methods to assess the physical development of obese adolescent children. We noted positive dynamics of the influence of the method of recreational activities of adolescents with I-II degree obesity.

Penelitian ini diarahkan untuk mendapatkan informasi kelayakan ekonomis berbagai cara semai serta melakukan analisis usahatani budidaya true shallot seed (TSS). Percobaan dilakukan di Brebes, Jawa Tengah, April–September 2017. Rancangan yang digunakan adalah Rancangan Acak Kelompok dengan enam kombinasi perlakuan metode semai (sebar, garit, dan soil-block) dan umur semai (30 dan 45 hari). Hasil penelitian menunjukkan bahwa cara semai soil-block umur 30 hari menghasilkan bobot umbi tertinggi. Produksi per hektar semai soil-block umur 30 hari adalah 29,3 ton/ha (bobot segar) atau 17,7 ton/ha (bobot kering). Indikator B/C ratio tertinggi (0,75) dan tingkat pengembalian marjinal tertinggi (27,769%) mengindikasikan bahwa cara soil-block umur 45 hari merupakan perlakuan yang paling ekonomis. Harga per semaian berkisar antara Rp37,6 – 42,6 sehingga biaya total semaian adalah Rp24,4 – 27,7 juta per hektar. Biaya sebesar ini berpotensi menghapus salah satu advantage penggunaan TSS karena tidak lebih murah dibanding biaya benih umbi per hektar. Walaupun menunjukkan potensi hasil cukup tinggi (18–29 ton/ha), namun karena efisiensi lahan rendah (54%) serta susut bobot tinggi (56%) maka probabilitas mengalami kerugian masih cukup tinggi. Hasil studi menyarankan penelitian lanjutan yang diarahkan untuk menekan biaya produksi semaian, meningkatkan produktivitas, meningkatkan efisiensi lahan, dan menurunkan susut bobot umbi.

Abstract

The study aimed to assess the economic feasibility of sowing methods and farm-budget of TSS cultivation. A trial was conducted in Brebes, Central Java (April–September 2017). RCBD with six treatment combinations of sowing method and sowing age, and four replications was employed. Results indicate that seedlings from soil block (30 days) produce the highest tuber weight. The fresh yield of using soil-block (30 days) is 29.3 tons/ha, while the dry yield is 17.7 tons/ha. Based on the highest B/C ratio and highest marginal rate of return, the soil-block (45 days) is assessed as the most feasible sowing method. The cost per seedling ranges from IDR 37.6 – 42.6, thus the total seedling cost is  IDR 24.4 – 27.7 millions/ha. This may potentially eliminate one advantage of using TSS because the seedling cost is not lower than the cost of purchasing seed bulbs. Producing high fresh yield (18 – 29 tons/ha) could not compensate low land efficiency (54%) and high weight loss (56%), so that the loss probability is still quite high. The study recommends further works needed to lower seedling cost, increase yield, increase land efficiency, and reduce the bulb weight loss.

Background: Solanum dasyphyllum is a plant with several ethno-medicinal uses as food and medicine in treatment of fever, skin diseases, inflammation, stomach ache and some systemic infections. To date there is little scientific validation of the folkloric claims of S. dasyphyllum compared to other species of the Solanaceae family. This study determined the antimicrobial and antioxidant potential of methanol extract and fractions of the leaves of S. dasyphyllum and analysed the phyto-constituents using GC-MS technique.Methods: The dried leaves of S. dasyphyllum were extracted by Soxhlet apparatus with 80% methanol and the crude extract subjected to Phytochemical screening and liquid-liquid fractionation. Crude extract and fractions were subjected to antimicrobial screening, minimum inhibitory concentrations (MICs) and minimum bactericidal/fungicidal concentrations (MBC/MFC) determination and time-kill kinetics study. Crude extract was assayed for antioxidant activity and analysed by GC-MS.Results: Percentage yield of S. dasyphyllum was 12.5% and tested positive for flavonoids, alkaloids, saponins, cyanogenic glycosides, tannins and reducing sugars. The crude extract and fractions were active on all the isolates at concentrations >0.5 mg/mL. MICs of the crude extract and fractions ranged between 0.25 and >4 mg/mL, MBC ranged between 1 and >4 mg/mL and MFC ranged between 0.5 and >4 mg/mL. The MBC/MIC ratio was >4 for dichloromethane fractions against S. aureus (ratio 8) and MFC/MIC ratio ethylacetate fraction against the fungi isolates (ratio 8). The time-kill kinetics study showed dichloromethane and ethylacetate fractions to be bactericidal with zero viable count at 4 - 6hours against the isolates. The crude extract displayed moderate antioxidant with weak DPPH radical scavenging activity. The GC-MS analysis showed 29 metabolites including the phenols and polyphenols derivatives, eucalyptol, levomenthol, benzofuranone derivative, diethyl phthalate, neophytadiene, 1-Docosene, 17-Pentatriacontene, Phytol, Thunbergol and esters of decanoic acid derivatives all of which are known to have anti-infective and anti-oxidant properties.Conclusion: This study therefore confirmed the ethno-medicinal claim of S. dasyphyllum and thus elucidates the potentials of the plant as a good source of bioactive compounds including those with strong anti-infective and antioxidant properties.

Background

Latrine is one of many emergency responses essential for people’s dignity, safety, health and well-beings. It is a major priority, and the coverage needs to be addressed with as much speed and effort as possible. This study finds out the latrine coverage and associated risk factors in Ambo town, Ethiopia.
Methods

A survey was conducted from December 2015 to April 2016 among the community found in Ambo town. About 321 households were recruited in the study. Data on latrine coverage and associated risk factors like socio-demographic characteristics, behavioral and environmental factors were collected using pretested questionnaire. Risk factors related to latrine coverage were tested to determine the potential of these factors to limit latrine availability in Ambo town.
Results

This study results showed that 265(82.3%) of subjects had a latrine. Among these majority of latrines 194(60.2%) were traditional pit latrines. About 123 (38.2%) of latrines found in this study, had a hand washing facility whereas, 142 (44.1%) had not these facilities. Factors like: religion, family size, and educational level of respondents were significantly associated with availability of latrines (P < 0.05).
Conclusions

Based on this study finding, the latrine coverage in ambo town is very good though the coverage of improved latrines still needs attention at all level of stakeholders. Most of latrines were traditional pit latrines. Enhancing the awareness level of the community about sanitation and its benefit would facilitate the coverage and the quality of latrines.

Purpose: To investigate dose escalation for brain metastases (BM) subvolumes with low cerebral blood flow (CBF) using dose-painting technology based on MR 3D arterial spin labeling (3D-ASL) images.Methods: A total of 50 patients with single BM were selected for this study. CT and MR simulation images, including contrast-enhanced T1-weighted (T1W) images and CBF images, were obtained. The gross tumor volume (GTV) was determined by fusion of contrast-enhanced CT and T1W images, and this volume was divided into high- and low-perfusion areas according to the difference in CBF. Sub-volume with less than 25% of the maximum CBF was defined as hypoxic region GTVH which was settled for dose escalation. The planning target volume (PTV) and PTVH were calculated from the GTV and the GTVH, respectively. The PTVN was calculated by subtracting the PTVH from the PTV. Plan 1 was defined as the conventional plan with a prescription dose of 60 Gy for the PTV. Plan 2 and Plan 3, respectively, escalated the prescription dose for the PTVH to 72 Gy with and without the maximum dose constrained based on Plan 1. Dosimetric indices were compared among the three plans.Results: On average, the GTV volume was 34.53 cm3, and the GTVH volume was 16.95 cm3, accounting for 49.09% of the GTV. Compared to Plan 1, the D2%, D98% and Dmean values of the PTVH escalated by 20.50%, 19.32%, and 19.60%, respectively, in Plan 2 and by 24.05%, 6.77%, and 17.00%, respectively, in Plan 3 (all P<0.05). The doses administered in Plans 2 and 3 were 73.67±0.34 Gy and 72.37±0.61 Gy, respectively (both P<0.05). In Plans 2 and 3, respectively, the conformity index of PTVH was increased by 45.45% and 63.64%; meanwhile, the homogeneity index was sacrificed, increasing from 0.04 to 0.05 and 0.11 (all P<0.05). Plan 2 achieved better values of D98% and Dmean, as well as a smaller increase in the homogeneity index, than Plan 3. The doses received by organs at risk (OARs) did not significantly differ between the conventional plans and the boost plans (all P >0.05).Conclusions: Targeted dose escalation guided by the 3D-ASL-based CBF differences in BM effectively escalated the dose delivered to low-CBF subvolumes without increasing the dose to OARs.
