The contribution of vaccination to global health, from the past to the present: mandatory or social duty?

Vaccines have saved millions of lives and reduced the severity of many infections, but today the reduction in vaccine coverage has been reflected in the resurgence of epidemics of mumps, whooping cough, measles and chickenpox. This has happened because many people do not recognize the effectiveness of vaccination and fear the side effects, in other words, the main concern is the safety of the vaccines. As a consequence, the greater responsibility of the individual and respect for his will can lead authorities to less vigorously promote the “duty of vaccination”, which is also a social duty. Unfortunately, however, the attitude of individuals is guided by their beliefs about health, which are often supported by an erroneous perception of risk arising from false news.

Effects of Trichoderma asperellum BV10 and Bacillus amyloliquefaciens BV03 in Meloidogyne incognita Control Considering Three Different Management Systems

Crop yield decrease is the main concern when a pathogen or plague is identified in an agriculture field. Thus, part of this issue can be attributed to plant-parasitic nematodes (PPNs), such as Meloidogyne species, due to, most of the time, the hard diagnosis, and non-specific symptoms. Its management is mainly based on chemical pesticides, followed by a few potential biological control agents, and the management system. Therefore, this study aimed to evaluate the effects of biological agents in Meloidogyne incognita control in different soil systems. For that, two biological products were chosen, Trichoderma asperellum BV10 and Bacillus amyloliquefaciens BV03, and soils were sampled from three different managements systems: (i) soybean no-tilled system at Goiás state, Brazil; (ii) forest soil at Goiás state, Brazil, and (iii) soybean conventional managed system at Mato Grosso do Sul state, Brazil. Biocontrol and growth promotion effects, volatile organic compounds (VOCs) and soil respiration were determined in vegetation house and laboratory, respectively. As a result, both BV10 and BV03 had significant nematode control activity, comparing to control treatment, in all the three soils systems. Plus, the number of immobile nematodes by potential VOCs had significant increase when BV03 was applied, while the application of BV10 agent raised the soil respiration rate. In conclusion, both biocontrol agents presented great efficiency in control M. incognita, with better performance of BV03. Lastly, more studies must be done to elucidate how the resident soil microbiome can influence on biocontrol agent establishment and performance, as well as the consequence of the application of biological products on soil microbiome network.

Soil loss estimation and severity mapping using RUSLE model and GIS: a case study in Megech Watershed, Ethiopia

AbstractBackground: Soil erosion is the most serious problem that affects economic development, food security, and ecosystem services which is the main concern in Ethiopia. This study focused on quantifying soil erosion rate and severity mapping of the Megech watershed for effective planning and decision-making processes to implement protection measures. The RUSLE model integrated with ArcGIS software was used to conduct the present study. The six RUSLE model parameters: erosivity, erodibility, slope length and steepness, cover management, and erosion control practices were used as input parameters to predict the average annual soil loss and identify erosion hotspots in the watershed. Results: The RUSLE estimated 1,399,210 tons yr-1 total soil loss from the watershed with a mean annual soil loss of 32.84 tons ha-1yr-1. The soil erosion rate was varied from 0.08 to greater than 500 tons ha-1yr-1. A severity map with seven severity classes was created for 27 sub-watersheds: low (below 10), moderate (10-20), high (20-30), very high (30-35), severe (35-40), very severe (40-45) and extremely severe (above 45) in which the values are in tons ha-1yr-1. The area coverage was 6.5%, 11.1%, 8.7%, 22%, 30.9%, 13.4%, and 7.4% for low, moderate, high, very high, severe, very severe, and extremely severe erosion classes respectively. Conclusion: About 82 % of the watershed was found in more than the high-risk category which reflects the need for immediate land management action. This paper could be important for decision-makers to prioritize critical erosion hotspot areas for comprehensive and sustainable management of the watershed.

PLANT BASED BIOAVAILABILITY ENHANCERS

Many of the synthetic as well as herbal drugs despite of their notable in vitro finding demonstrate insignificant in vivo activity majority of times due to poor bioavailability. As per Biopharmaceutical Classification System (BCS) one of the main concern is low solubility and/or permeation of drugs resulting in reduced absorption and poor bioavailability. To overcome these issues the various strategies have been adopted including use of permeation enhancers which are also known as bioenhancers. Bioenhancers are synthetic or natural compounds that increases the bioavailability of drugs and nutrients such as vitamins, amino acids, minerals, etc. into the systemic circulation and at the site of action for exhibiting improved therapeutic action. By improving bioavailability, bioenhancers can lead to reduction in drug dose, decrease in the treatment period and can circumvent the problem of drug resistance. Numerous studies have reported application of synthetic bioenhancers. On the other hand, owing to the natural origin, plant based bioenhancer can serve as better alternative. Literature review have revealed that the plant-based bioenhancers have been used in with a wide varieties of drugs including antibiotics, antiviral and anti-cancer. These can be categorized based on their sources and the mechanism of activity. This review will provide a systematic and detailed overview of the various plant based bioenhancers and applications.

Microwave Irradiated Synthesis of Pyrimidine Containing, Thiazolidin-4-ones: Antimicrobial, Anti-tuberculosis, Antimalarial, and Anti-protozoa evaluation

Aim: This study aims to synthesize thiazolidine-4-one compounds with a pyrimidine nucleus and evaluate against different species of bacteria, fungi, protozoa, and the malaria parasite. Background: Microwave irradiation was the best method for synthesizing the thiazolidin-4-one ring system. It took only 15 minutes for synthesizing thiazolidin-4-one while the conventional method required 12 hours. The rapid reaction was the main concern of this research. Objective: Pyrimidine and Thiazolidin-4-one nucleus have broad-spectrum biological activity and when it is introduced with other hetero atoms containing moiety, many types of biological activities have been found; antimicrobial, anti-tuberculosis, anti-protozoa, antimalarial are the main activities. The activity of these compounds inspired us to do extra research on Thiazolidin-4-one fused pyrimidines with different functional groups. The aim of this is to synthesize a combination of these two ring systems in less time by using a microwave irradiation method and to evaluate new compounds for different bioactivity. Method: 2-(4-Chlorophenyl)-3-(4-(substituted phenyl)-6-(substituted aryl) pyrimidin-2-yl) thiazolidin-4-ones (6A-J) were synthesized by microwave irradiation to save energy and time. The structure of all newly synthesized motifs was characterized by spectral analysis (1H NMR, 13C NMR, IR, spectroscopy) and screened for antibacterial activity against Escherichia coli, Pseudomonas aeruginosa, Staphylococcus aureus, and Streptococcus pyogenes, antifungal activity against Candida albicans, Aspergillus niger, Aspergillus clavatus, anti-tuberculosis activity against M. tuberculosis H37RV, antimalarial activity against Plasmodium falciparum and anti-protozoa activity against L. mexicana and T. cruzi. Result: Because of microwave irradiation synthesis, time period is very less for preparing the new compound. Biological response given by compounds 6B, 6C, 6D, 6E, 6G, 6H, and 6J was found excellent. Conclusion: Good yield with purity of the newly synthesized thiazolidine-4-one compounds obtained in less time by using microwave irradiation. The biological response of some of the compounds of this series was found excellent

Optimist, Pessimist or Engineer - Conductivity Based on Need Not Fashion

An optimist says the glass is half-full, a pessimist half-empty, whereas a good engineer says that the glass is twice as big as it needs to be. There has been much debate over the years about the relative functionality, application and even necessity of proppant in delivering effective hydraulic fractures. Often these debates have been directly linked to major changes in core frac applications, more recently in the dominant North American onshore unconventional market. However, the debates have all too often used broad or unclear brush strokes to describe shifting fracture requirements. Meanwhile, the developing oilfield in the rest of the world resides in more permeable areas of the resource triangle, great care must be taken to ensure that conventional lessons hard learned are not lost, but also that unconventional understanding develops. Over recent years there have been many debates and publications on the relative value of the use of proppant (and associated conductivity), although the true question was about appropriate fracture design in different rock/matrix qualities and environments. Certainly, the vast majority of fracturing engineers appreciate the difference between continuous proppant-pack conductivity and other techniques, such as infinite conductivity, pillar fracturing or duning designs. However, there is increasing evidence that conventional fracturing is suffering from populist attitudes, leading to ineffective fracturing. Additionally, and just as impactful, that unconventional fracturing continues to rely on the lessons learned and physics derived directly from our conventional experience but applying this in an entirely different environment. Primarily, the main concern is with the transfer of recent lessons learned and techniques utilised in one rock quality and environment, to an entirely different scenario, resulting in the misapplication, reduced IP30, poorer NPV or reduced long term EUR and IRR. Examples will be referenced where appropriate proppant selection and frac design can be the difference between success and failure. Fundamentally, we have not sufficiently developed our understanding of the role of proppant and conductivity, for application in unconventionals and thereby rely far too much on our previous conventional thinking. While at the same time we are exporting often inappropriate unconventional populist practice into very conventional environments, thereby potentially achieving the abhorrence of the worst of both worlds. This paper will describe and address scenarios where appropriate engineering selection, rather than popularity-based decision making, has resulted in a successful outcome. It will also attempt to ensure that we show the importance of studying your rock, in anticipation of engineering design, and that this should be a key consideration. The paper will also suggest that as an industry we urgently need to address our approach to consideration of conductivity, placement and importance and ensure that unconventional knowledge and learning progresses with a beneficial outcome for all.

The response of law enforcement agencies and police officers' experiences under the Covid-19 state of alarm in Catalonia, Spain

PurposeLaw enforcement agencies and police officers' efforts were crucial to oversee the public health measures and legal regulations introduced during the Covid-19 pandemic. The study had two objectives: to examine the strategies implemented by law enforcement agencies in Catalonia (Spain) to monitor the pandemic and to explore the adverse working conditions of police officers and their personal difficulties during the state of alarm.Design/methodology/approachA total of 96 experienced police officers completed a closed-ended, anonymous online survey. In addition, complementary information was collected about the management of law enforcement agencies through open interviews. A descriptive analysis was carried out and the association between variables was explored.FindingsIn general terms, law enforcement agencies managed the uncertainty of the situation, with a focus on official information and communication channels between officers. However, many difficulties were reported by the police officers, such us inconsistency between rules, lack of preventive material or changes in work schedules. Besides, the officers' main concern, beyond the emotional impact suffered during this period, was the possibility of being infected or infecting others.Practical implicationsThe congruence between the job requirements and resources, as well as the increase of communication channels during situations of high risk are important variables to assure good job development and personal satisfaction of police officers.Originality/valueTo the knowledge of the authors, at the time of writing this paper, this is the first study in Spain to explore the management of law enforcement agencies and police officers' personal experiences during the Covid-19.

Do the Child Welfare and Protection Services Involve Children in Cases With Parental Mental Health Problems? A Norwegian Case-File Study

Background: Parental mental health problems is a common source of concern reported to child welfare and protection services (CWPS). In this study we explored to what extent the child was invited to participate in the investigation process. We aimed to study: (a) what was the current practice in the child protection service in Norway when the CWPS received a report of concern about children whose parents were affected by mental health problems or substance abuse, (b) to what extent were children involved and consulted, (c) which factors predicted the decision to involve the children, and (d) in cases in which conversations with children were conducted: what was the main content of the conversations.Method: The study was a cross-sectional case file study (N = 1,123). Data were collected retrospectively from case records in 16 different child protection agencies. The cases were randomly drawn from all referrals registered in the participating agencies. Differences in how investigations were conducted in cases with and without concerns about parental mental health were analyzed using t-tests and chi-square testes. Predictors of child involvement in cases with parental mental health problems (N = 324) were estimated by logistic regression analyses.Results: When the referral to the CWPS contained concerns about parental mental health, there were more consultations with parents, more frequent home visits and the investigation took longer to conclude. The children, however, were less likely to be involved. Children in such cases were consulted in 47.5% of cases. Predictors for involving the children in those cases were child age, concern about the child's emotional problems and if the child was known from previous referrals.Conclusion: In Norwegian child protection investigations, in which there were concerns about the parent's mental health, conversations with children were conducted to a significantly lower degree compared to cases where the child's problem was the main concern. In such cases, the CWPS workers have to overcome a threshold before they consult with the child. The threshold decreases with child age and when case worker already knows the child.

Triple dislocation around the knee joint: a case report

Background Dislocation of the knee is a serious and potentially limb-threatening injury. There are three types of dislocation around the knee joint: patellofemoral, tibiofemoral, and tibiofibular. Tibiofemoral dislocation is the variant that is deemed the most serious, with a higher risk of compromise to the popliteal artery and common peroneal nerve. Although simultaneous dislocations of two types have been described, there has been no such description of all three types occurring simultaneously. Case presentation We present a case of a 40-year-old hairdresser who suffered a fall off her moped in Spain, and simultaneously dislocated all three articulations around the knee. Diagnosis was achieved with clinical examination, plain films, and computed tomography and magnetic resonance imaging scans. Management consisted of initial surgical debridement and reduction with stabilization of the affected joints. Conclusion Dislocation of the knee is an uncommon but life changing and potentially limb-threatening injury. It should always be suspected in trauma patients who present with multiligamentous knee injuries. The main concern is of neurovascular compromise to the lower leg, namely, the popliteal artery and common peroneal nerve. The treatment of multiligamentous knee injuries for most patients is surgical treatment with physiotherapy and adequate stabilization of the knee joint. Close monitoring of progress of the knee in terms of persistent laxity, range of movement, and functional status is required for at least 1-year post injury. Current evidence suggests that, despite good functional outcomes for knee dislocations in the short term, the prevalence of post-traumatic osteoarthritis is high in the long term.
