Aging is a natural process through which all living things pass. It has been defined as the sum of the alterations that occur in an organism with the passage of time, which can lead to functional and mental losses; It is also known as a natural phenomenon of the life cycle, starts from the moment of conception and ends with death, however, despite being identified as a process of being, it is difficult to accept it as a reality. Today, the population index of the elderly is high, added to this, the number of pathologies of old age generates an overflow of needs related to health services, in which Colombia has a deficit, which causes abandonment and neglect in the medical care, giving way to this becoming a national health issue. In the same way, the government and its res- pective entities are not prepared to assume the physical, psychological and health consequences that this implies, which is why social deterioration is evidenced in the face of comprehensive care for the elderly. On the other hand, the elderly are also victims of helplessness originating in their direct family nucleus, due to various factors that alter the emotional bond and their parental responsibility.

Economic law incorporates the normative and principles framework that surrounds the various activities where legal foundation is required, due to legal order and reference when the economic agents or sectors know the legal framework that characterizes the action of the companies. The legal stipulation detached from economic law has reached its limit, since circumstances continue to appear that are not contemplated and that are conceived as atypical, little illustrative appreciation of the reality that companies that in no case are prescribed or confined have in front. One of the legal theories created in recent decades is the economic analysis of Law: the legal phenomena explained from the Economy. For his avant-garde, he had more critics than followers.

Traumatic Peroneal Nerve Injuries
Authors: Mackay Matthew J. , Ayres Jack M. , Harmon Ian P. , Tarakemeh Armin , Brubacher Jacob , Vopat Bryan G.
Published: January 2022

Background:

The common peroneal nerve (CPN) is the most commonly injured peripheral nerve of the lower extremity in patients with trauma. Traumatic CPN injuries have historically been associated with relatively poor outcomes and patient satisfaction, although improved surgical technique and novel procedures appear to improve outcomes. Given the variety of underlying injury modalities, treatment options, and prognostic variables, we sought to evaluate and summarize the current literature on traumatic CPN injuries and to provide recommendations from an analysis of the included studies for treatment and future research.

Methods:

A systematic review was performed using PubMed, Embase, and Cochrane databases per the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Search terms consisted of variations of “peroneal nerve” or “fibular nerve” combined with “injury,” “laceration,” “entrapment,” “repair,” or “neurolysis.” Information with regard to treatment modality, outcomes, and patient demographic characteristics was recorded and analyzed.

Results:

The initial search yielded 2,301 articles; 42 met eligibility criteria. Factors associated with better outcomes included a shorter preoperative interval, shorter graft length when an interposed graft was used, nerve continuity, and younger patient age. Gender or sex was not mentioned as a factor affecting outcomes in any study. Motor grades of ≥M3 on the British Medical Research Council (MRC) scale are typically considered successful outcomes. This was achieved in 81.4% of patients who underwent neurolysis, 78.8% of patients who underwent end-to-end suturing, 49.0% of patients who underwent nerve grafting, 62.9% of patients who underwent nerve transfer, 81.5% of patients who underwent isolated posterior tibial tendon transfer (PTTT), and 84.2% of patients who underwent a surgical procedure with concurrent PTTT.

Conclusions:

Studies included in this review were heterogenous, complicating our ability to perform further analysis. It is not possible to uniformly advocate for the best treatment option, given diverse injury modalities and patient presentations and a variety of prognostic factors. Many studies do not show outcomes with respect to injury modality. Future studies should show preoperative muscle strengths and should clearly define outcomes based on the injury modality and surgical treatment option. This would allow for greater analysis of the most appropriate treatment option for a given mechanism of injury. Newer surgical techniques are promising and should be further explored.

This interaction either reduced the effect or no effect or increased drug effect. Patient in intensive care unit (ICU) are highly susceptible to drug interactions because of the complexity of the drugs regimens they receive. Drugs may affect the Pharmacokinetics of the critical ill patients and subsequently altered the pharmacological response, which potentially lead to serious adverse drug events. Drug-drug interaction (DDI) are considered predictable and thus avoidable and manageable.
El (invisible) papel de los traductores e intérpretes durante la COVID-19: estudio de las publicaciones de El País
Authors: Cedillo Corrochano Carmen Mª
Published: January 2022

Resumen: El (re)conocimiento social y mediático de los traductores e intérpretes ha sido un objeto de estudio de interés en los últimos años dentro del propio colectivo. Varios han sido los trabajos (Campos y Fernandes, 2011; Cedillo, 2017; Sldl Bah, 2015) dedicados a la investigación de la presencia mediática en España de los traductores e intérpretes y todos ellos han concluido que su tratamiento por parte de los medios de comunicación, masivos y sociales, es muy limitado. Tal y como subrayan, los periódicos españoles, en concreto, no conceden grandes espacios a las actividades traslativa e interpretativa. Sin embargo, ambas actividades se han puesto especialmente a prueba en los últimos meses. Durante la pandemia mundial ocasionada por la COVID-19, los traductores e intérpretes han sido (y son) responsables de salvaguardar el derecho a la comunicación /información en igualdad de condiciones de todas las sociedades actuales, multiculturales y multilingües. La función que han desempeñado (y aún desempeñan), derribando las barreras comunicativas en un periodo de crisis sanitaria mundial, ha sido (y sigue siendo) esencial para la comprensión de lo acontecido por parte de los alófonos. Así pues, el presente estudio persigue evaluar el protagonismo que se le ha otorgado ante este escenario a los traductores e intérpretes en el periódico más popular de España. A este fin, se analizarán cuanti-cualitativamente las publicaciones de El País sobre los traductores e intérpretes desde el 14 de marzo de 2020 al 14 de marzo de 2021. El corpus textual, extraído de la hemeroteca digital del periódico, permitirá descubrir los escasos contenidos publicados por El País durante un año sobre los traductores e intérpretes y el invisible papel que han desempeñado durante la COVID-19 para este medio.

Vibrational Data Communication Tools and Methods for Mining and Oil and Gas Extraction
Authors: Islam Md Shahriar , Berscheid B. , Wiens T.
Published: January 2022

For the purpose of exploration and extraction, the drilling process in the mining and oil and gas industries is very complicated because of the obvious invisibility of the operation of the drill bit. Acoustic/vibrational telemetry has been of keen interest because it is so far the only method that allows a high data transfer rate as well as less data loss, over other methods. The method certainly depends on the use of the right communication tools and efficient communication schemes to achieve the highest data transfer rate. Although the acoustic method provides a very high data transmission rate, it also has its limitations. However, limitations can be overcome through certain approaches and the use of technologies. The proper use of a communication device with the steel pipe is the most important factor to consider so that the transducer works as the right actuator for the pipeline. The type of sensor that is used to pick up the data also plays a major role because signals are most likely to attenuate, and a sensitive sensor is necessary to collect these attenuated signals. This research demonstrates the use of a transducer as a communication device and oil and gas pipe as the medium of data transmission. The transducer can be used both as an actuator driver and as a receiver sensor. A new piezoelectric transducer was manufactured for this research, which was used with a test setup of a total 184 ft length of six oil and gas pipes. The test setup performed well and data were sent through this setup successfully. A communication scheme is developed using novel theories to achieve the highest data transfer rate. The scheme is tested with the transfer function data obtained from the experimental system. The communication scheme developed outputs a signal, which is a type of binary phase-shift keying signal data along with an equalizer filter. Then the signals developed from the scheme are used in the actual experimental setup to test the speed of the transmission and bit error rate (BER). For the six oil and gas pipes setup, the scheme provides a data transmission of 153 bits/sec (bps) with zero error percentage, which is high enough to use in any oil and gas industry.
The air pollution tradeoff in India: Saving more lives versus reducing the inequality of exposure

Chronic exposure to ambient fine particulate matter (PM2.5) represents one of the largest global public health risks, leading to millions of premature deaths annually. For a country facing high and spatially variable exposures, prioritizing where to reduce PM2.5 concentrations leads to an inherent tradeoff between saving the most lives and reducing inequality of exposure. This tradeoff results from the shape of the concentration-response function between exposure to PM2.5 and mortality, which indicates that the additional lives saved per unit reduction in PM2.5 declines as concentrations increase. We estimate this concentration-response function for urban areas of India, finding that a 10 unit reduction in PM2.5 in already-clean locations will reduce the mortality rate substantially (4.2% for a reduction from 30 to 20 µgm-3), while a 10 unit reduction in the dirtiest locations will reduce mortality only modestly (1.2% for a reduction from 90 to 80 µgm-3). We explore the implications of this PM2.5/mortality relationship by considering a thought experiment. If India had a fixed amount of resources to devote to PM2.5 concentration reductions across urban areas, what is the lives saved/inequality of exposure tradeoff from three different methods of employing those resources? Across our three scenarios—1) which reduces exposures for the dirtiest districts, 2) which reduces exposures everywhere equally, and 3) which reduces exposures to save the most lives—scenario 1 saves 18,000 lives per year while reducing the inequality of exposure by 65%, while scenario 3 saves 126,000 lives per year, but increases inequality by 19%.

This study aimed to investigate the prognostic factors related to overall survival (OS) and cancer-specific survival (CSS) in patients with de novo metastatic nasopharyngeal carcinoma (NPC) aged ≥65 years in non-endemic areas. The Surveillance, Epidemiology, and End Results (SEER) database was queried for elderly patients with M1 stage NPC at initial diagnosis between 2004 and 2016. This study examined 100 patients and evaluated the relationship of gender, age, race, pathological grade, T stage, N stage, number of primary tumors, site of metastasis, number of metastatic organs, and other related factors with OS and CSS. The median survival and follow-up time were 10 and 48 months, respectively. The survival curves of race, N stage, bone metastasis, radiation, and chemotherapy significantly affected OS on the log-rank test. Race, bone metastasis, and chemotherapy were independent prognostic factors of OS. Bone metastasis was associated with poor survival. The survival curves of CSS were significantly differed between races, the number of primary tumors, and bone metastasis. In Cox regression multivariate analysis, only the number of primary tumors had an independent effect on prognosis. This study revealed that chemotherapy prolonged survival in elderly patients with metastatic NPC, whereas bone metastasis shortened survival.

Background: Compound Dragon's blood capsule (CDC) is a patent medicine mainly composed of dragon’s blood (Dracaena cochinchinensis (Lour.) S. C. Chen), notoginseng (Parmx notoginseng (Burk.) F. H. Chen) and borneol (C10H18O) for the treatment of stabilize coronary heart disease (CHD) and myocardial ischemia (MI). This paper is to investigate the anti-myocardial ischemia properties of CDC both in vivo and vitro.Methods: The fingerprint of CDC was established by UPLC-Q/TOF-MS. The hypoxia/reoxygenation (H/R) model was established by using H9c2 cells. The levels of LDH, SOD and MDA were detected by colorimetric method. Moreover, the MI model of rats was established by isoprenaline hydrochloride (ISO), the mortality rate was recorded, the changes in J point of electrocardiogram were determined, the expressions of the myocardial markers, oxidative stress markers (CK, CK-MB, LDH and SOD) and inflammatory mediators (TNF-α, IL-6, IL-10, IL-1β and NO) in serum were detected. Results: The fingerprint of CDC was established and 10 mainly active components were identified: 7,4'-dihydroxyflavone, resveratrol, loureirin A, loureirin B, pterostilbene were identified from Dragon's blood, notoginsenoside R1, ginsenoside Rg1, ginsenoside Rb1, oleanolic acid, ginsenoside Rd were identified from notoginseng. In vitro study, CDC significantly improved H9c2 cell viability and SOD level (P < 0.05), decreased LDH and MDA level (P < 0.05). In vivo study, CDC increased survival rate and SOD level of serum, decreased J-point of ECG, CK-MB, LDH, TNF-α, IL-6, IL-10 level (P < 0.05).Conclusions: CDC had a significant anti-myocardial ischemia effect by alleviating inflammation and oxidative stress, suggesting that CDC is a suitable adjuvent to treat CHD, dragon’s blood has the prospect of developing other new drugs.
Arabidopsis cyclophilins direct plasmodesmata-targeting of mobile mRNA via organelle hitchhiking

Published: January 2022

Plants selectively transport mobile mRNAs through intercellular pores, plasmodesmata (PD), to distribute spatial information for synchronizing meristematic differentiation with environmental dynamics. However, how plants recognize and deliver mobile mRNAs to PD remains unknown. Here, by using RNA-live cell imaging, we show that mobile mRNAs hitchhike on organelle trafficking to transport to PD. Perturbed cytoskeleton organization or organelle trafficking severely disrupts the subcellular distribution of mobile mRNAs. We further show that Arabidopsis rotamase cyclophilins (ROCs), which are organelle-localized RNA-binding proteins (RBPs), specifically bind mobile mRNAs on the surface of organelles to direct PD-targeting. Arabidopsis roc quadruple mutants showed reduced in PD-targeting of mobile mRNAs, along with phenotype alterations. ROCs can move intercellularly and form RNA-protein complexes in phloem, suggesting the roles of ROCs in delivery of mobile mRNAs through PD. Our results highlight that an RBP-mediated hitchhiking system is purposely recruited to orient plant-mobile mRNAs to PD for intercellular transport.

Published: January 2022

Background: The number of cluster Randomized Controlled Trials (cRCTs) have been increasing and application in pediatrics is also growing. However, we did not know the quality of cRCTs in pediatrics and no previous study has comprehensively analyzed cRCTs in pediatrics. To investigate the status of cRCTs in pediatrics and analyzed influencing factors of the methodological quality.Methods: Through a search of 10 highest-impact-factor journals from PEDIATRICS and MEDICINE, GENERAL & INTERNAL, we identified cRCTs published from 1 January 2015 to 7 June 2020. The associations between study factors and grade of ROB (Risk of Bias) quality were analyzed by Pearson’s chi-squared test.Results: A total of 73 cRCTs were included. For the number of cRCTs, it has fluctuated in the past five years. For the International Classification of Diseases Eleventh Revision (ICD-11), 34.2% cRCTs could not be classified, of which more focused on vaccines; 15.1% cRCTs were classified into "X Extension Codes", of which more focused on vaccines and school bullying. For research settings, studies were concentrated in schools, communities, hospitals, clinics, and kindergartens, of which schools (36.5%) were the most. The number of clusters ranged from 1 to 1533 (M=28) and the participants ranged from 135 to 190,238 (M=1903). For the results of ROB assessment, 31 cRCTs were in high-quality, 28 were in low-quality, and 14 were unclear. The majority of cRCTs provided flow diagrams (87.8%), registered (98.6%), and made a distinction between primary and secondary outcomes (86.5%).Conclusions: The further improvement of the quality of cRCTs in pediatrics is needed, particularly in the terms of randomization, allocation concealment, and blinding. Writing and publishing the protocol can enhance transparency. Comply with of CONSORT statement for future studies is needed.

Based on meteorological and dust devil intensification observation data in the desert transition zone of the Xiaotang region in the northern margin of the Taklimakan Desert, and combined with GPS sounding in the hinterland of the Taklimakan Desert, this study investigated the improvement and evaluation of the dust devil parameterization scheme. The results indicate that the thermodynamic efficiency of dust devils after improvement was significantly higher than that before improvement, improving the values by 84.7%, 63.9%, 25.6%, 13.3%, 12.5%, 22.7%, 26.6%, 26.9%, and 21.4% for the hourly intervals from 09:00–17:00, respectively. The annual occurrence of dust devils after improvement was 431 times, 55.2% more than before improvement. The correlation coefficients of convective boundary layer height after improvement was 0.96, higher than that before improvement (0.908). After the improvement, the total annual dust emission time was 181.3 h, 95.9% less than that calculated using the day length before improvement, and 31.8% more than that calculated using sunshine time before improvement. After the improvement, the average vertical dust flux of a single dust devil was 0.25 m2/s, 68.8% less than that before improvement. After the improvement, the average annual dust emission from dust devils per square kilometer was 15.3 t/km2, significantly lower than the value of 320.5 t/km2 before the improvement, approximately one-twentieth of the value.
