Summary
In Brazil, high-yield soybean [Glycine Max (L). Merrill] – corn (Zea mays L.) double cropping system might be nitrogen (N)-limited and additional N fertilization can be beneficial. Early application of N in soybean reduces the symbiotic N fixation (SNF) efficiency and/or establishment. One alternative to avoid SNF impairment is to apply N between the beginning pod (R3) and seed-fill (R5) stages through the use of controlled release fertilizers. In this study, N was applied at 50 kg ha−1 as common urea (CU) or controlled release urea (CRU) with different lag periods until N release starts (30 days, 60 days, or 1:1 mix of both lag times) in a randomized complete blocks design with six treatments and four replicates under tropical and subtropical conditions. CU was applied after soybean emergence (VE) or at the beginning pod (R3), and CRU only at VE. Using urea labeled with 15N isotope, we analyzed the N source used by soybean (fertilizer, soil, or SNF) and SNF parameters. On average, CRU – 30 days, CRU – 1:1 mix (30 + 60 days) and CU applied at the R3 stage increased grain yield by 9.2% (354 kg ha−1) compared to the control. N derived from all fertilizer treatment were almost 35 kg N ha−1, a high N recovery efficiency of 68%. The SNF was not impaired by CU and CRU and accounted for 71% (220 kg N ha−1) of total N uptake. In the conditions of the experiments, fertilization of 50 kg N ha−1 as CRU was shown to be effective to supply N in late soybean demand (R3 stage), increasing yield without damaging the SNF process in high-yield environments.

AbstractThe oceans store a substantial fraction of carbon as calcium carbonate (CaCO3) and organic carbon (Corg) and constitute a significant component of the global carbon cycle. The Corgand CaCO3flux depends on productivity and is strongly modulated by the Asian monsoon in the tropics. Anthropogenic activities are likely to influence the monsoon and thus it is imperative to understand its implications on carbon burial in the oceans. We have reconstructed multi-decadal CaCO3and Corgburial changes and associated processes during the last 4.9 ky, including the Meghalayan Age, from the Gulf of Mannar. The influence of monsoon on carbon burial is reconstructed from the absolute abundance of planktic foraminifera and relative abundance ofGlobigerina bulloides. Both Corgand CaCO3increased throughout the Meghalayan Age, except between 3.0–3.5 ka and the last millennium. The increase in Corgburial during the Meghalayan Age was observed throughout the eastern Arabian Sea. The concomitant decrease in the Corgto nitrogen ratio suggests increased contribution of marine organic matter. Although the upwelling was intense until 1.5 ka, the lack of a definite increasing trend suggests that the persistent increase in Corgand CaCO3during the early Meghalayan Age was mainly driven by higher productivity during the winter season coupled with better preservation in the sediments. Both the intervals (3.0–3.5 ka and the last millennium) of nearly constant carbon burial coincide with a steady sea-level. The low carbon burial during the last millennium is attributed to the weaker-upwelling-induced lower productivity.

Published: January 2023

AbstractSALTMED model performance was evaluated by comparing simulated and observed soil water content, dry matter (DM) yield, yield and water productivity (WP) data of field-grown bell pepper (Capsicum annuum L.) under Mediterranean climatic conditions irrigated with surface and subsurface drip systems. Simulation data were obtained from field experiments performed in 2016 and 2017. Treatments were full irrigation (I100), conventional deficit irrigation at 75 and 50% actual crop evapotranspiration (ETa; I75 and I50), regulated-deficit irrigation (RDI) and partial root-zone drying (PRD) at 50% ETa using surface (SfDI) and subsurface drip systems (SbDI) on a clay-loam soil, in a split-plot with four replications. Results showed that 56 and 29 mm less irrigation water was applied to SdDI100 in 2016 and 2017, respectively, than SfDI100; RDI used 27 and 77 mm less irrigation water than SfDI100 in experimental years, respectively. SbDI and SfDI performed similarly for bell pepper yield, DM and WP. However, the effect of irrigation treatments on yield, DM and WP was significant. I100 showed the highest yield (74.9 and 71.1 t/ha in 2016 and 2017, respectively), followed by RDI in 2016; I100, RDI and I75 produced greater yield than other treatments in 2017. PRD50 and I50 produced the least yield (49.8 and 45.9 t/ha in 2016 and 2017, respectively). SbPRD50 and SbI50 had the greatest WP value under SbDI in the experimental years. Results showed that the SALTMED model simulated yield, DM, soil water content and WP reasonably well (R2 = 0.95, 0.97, 0.98 and 0.74, respectively).

AbstractDeployment of artificial wreck reefs (AWRs) near natural reefs can influence fish assemblages on both reefs. Here, we assessed fish attitudes (abundances, biomass and species richness) according to different level complexity areas of wrecks, feeding guilds of fish and body size of fish of two identical AWRs deployed at the same depth (36.6 m) and different distances from natural reefs. Scuba divers used visual census method to sample fish communities at wrecks for two years. An average of 2346 individuals per dive belonging to 52 species were observed on wrecks combined. Both mean fish abundance and mean biomass did not differ significantly between wrecks. Mean species richness was significantly greater at9 EylülthanAlaybey. Planktivore was the most abundant feeding guild on wrecks, and its abundance statistically differed between AWRs. The comparisons of fish assemblages at the different level complexity areas of the wrecks show differences, the highest mean abundances were recorded at the areas of low complexity of the wrecks. The results of this study show that although deploying artificial wreck reefs near to natural rocky reefs catalyses fish colonization, it does not present an exact influence on the fish communities of AWRs. We have not known yet how creating an artificial wreck reef affects fish community of natural reefs. With giving extra importance to the choice of deployment area, AWR applications may transform to win-win projects for both the marine environment and recreational users, such as divers and anglers.
Antidepressant medications in dementia: evidence and potential mechanisms of treatment-resistance

Published: January 2023

AbstractDepression in dementia is common, disabling and causes significant distress to patients and carers. Despite widespread use of antidepressants for depression in dementia, there is no evidence of therapeutic efficacy, and their use is potentially harmful in this patient group. Depression in dementia has poor outcomes and effective treatments are urgently needed. Understanding why antidepressants are ineffective in depression in dementia could provide insight into their mechanism of action and aid identification of new therapeutic targets. In this review we discuss why depression in dementia may be a distinct entity, current theories of how antidepressants work and how these mechanisms of action may be affected by disease processes in dementia. We also consider why clinicians continue to prescribe antidepressants in dementia, and novel approaches to understand and identify effective treatments for patients living with depression and dementia.

AbstractIn the seventeenth and eighteenth centuries, new patterns of knowledge, credit, and capital were created by global expansion. These, in turn, created new opportunities for groups of people who previously had little access to global trade. These individuals—women as well as men—increasingly engaged in commercial transactions, some of them relatively autonomous, others challenged and hindered by various forms of institutional control and constraint. Emphasising the intimate nature of networks means examining the quality rather than the quantity of certain networks, which ultimately facilitates a shift away from well-known historical agents such as influential merchants, powerful politicians, and various nobility and royals. The Gender, Intimate Networks, and Global Commerce in the Early Modern Period forum seeks to add to our knowledge of the diverse ways that intimate economic networks developed in both the Atlantic and Indian Ocean worlds, in Europe as well as en route elsewhere, among the well-off as well as the relatively poor, and among free people as well as the enslaved.

Published: January 2023

AbstractThis paper’s content focuses on designing and prototyping a robotic brace dedicated to treating scoliosis. Scoliosis is an abnormal spinal curvature affecting 1–3% of children and constitutes a major therapeutic problem. In moderate cases of deformity, passive brace treatment is performed. However, this approach can lead to important patient discomfort. So, we propose a robotic solution providing greater mobility and the possibility of adapting the procedure to each patient. The robotic brace we built and tested is composed of three specific rings adapted to the patient’s torso. Each independent module of two consecutive rings is movable through a Stewart–Gough platform-type mechanism. As the robotic brace is lightweight, it brings better portability and improves the patient’s comfort.The first part of the paper shows the state of the art of bracing techniques: from passive to active orthoses. Next, the mechatronics of the device is detailed, and the robot’s kinematic models are developed. The motion control principle is given. In the last part, motion tests were administered with a healthy human to validate the brace architecture choice and its position and motion control strategies.
Persisting while changing over time: modelling the historical biogeographic of cave crickets (Orthoptera, Grylloidea) in Neotropics

Abstract
Using species distribution modelling (SDMs) techniques, we predicted the biogeographic history of crickets commonly found in Neotropical caves as a way to detect potential long-term environmental refuges in South America. Our models were built based on a thorough investigation of existing database regarding the genus Endecous Saussure, 1878 (Ensifera: Phalangopsidae) occurrences. The predictions of their distribution were obtained for two paleoclimate scenarios (LGM — 21 ka and Mid-Holocene — 6 ka), the current climate scenario (0 ka) and one future global warming climate scenario (RCP8.5, 2080–2100). Our findings suggest that in the past, the potential distribution of the crickets was wider, with potential forest corridors connecting different karst areas with caves within their occupancy area. The future prediction indicates a drastic reduction in their spatial distribution with an increased potential for isolation in subterranean ecosystems. Atlantic humid forest patches and caves represent the main environmental refuges for these crickets. Considering the ongoing impacts on surface environments and future climate change, the conservation of caves and karst landscapes has become one of the main strategies for the maintenance of these crickets and all the correlated subterranean communities.

AbstractReproductive strategies for specific populations are closely related to environmental factors. Consequently, they are fundamental for conservation plans and the management of threatened habitats like salt marshes. From this viewpoint, germination strategy under different temperatures and salt conditions, voltammetric parameters and molecular analysis were performed and compared in six Halocnemum populations (four of H. cruciatum and two of H. strobilaceum) growing on Mediterranean (Balearic, Tyrrenic and Adriatic) and Red Sea coasts to establish the relation to environmental variables. Significant interpopulation differences were found in all the evaluated parameters. The Mediterranean populations showed a variable opportunistic germination strategy that was directly related to the drought period length at the studied sites. Consequently, potential environmental predictors of seed response were identified. The most noteworthy were bioclimate, soil texture, continentality index, winter temperatures and summer precipitations. Additionally, voltammetric parameters were evidenced as indicators of maternal plant stress levels and, thus, as potential determinants of future seed responses. The phylogenetic analyses showed a split into two species that did not correspond to germination response. The phylogeographic analyses showed interpopulation differences in haplotype composition for H. cruciatum, but not for H. strobilaceum. In conclusion, the tight connection between seed responses and the ecological parameters of natural populations as an adaptation for successful seedling emergence was proved regardless of its phylogenetic relations.
Anarchy and Its Overlooked Role in Health and Healthcare
Authors: Essex Ryan 
Published: January 2023

AbstractIn this paper, I will argue that a number of well-known health interventions or initiatives could be considered anarchist, or at the very least are consistent with anarchist thinking and principles. In doing this I have two aims: First, anarchism is a misunderstood term—by way of example, I hope to first sketch out what anarchist solutions in health and healthcare could look like; second, I hope to show how anarchist thought could stand as a means to improve the health of many, remedying health inequalities acting as a buffer for the many harms that threaten health and well-being. On this second point, I will argue that there are a number of theoretical and instrumental reasons why greater engagement with anarchism and anarchist thinking is needed, along with how this could contribute to health and in addressing broader injustices that create and perpetuate poor health.

Published: January 2023

AbstractObjective:Stunted children have an increased risk of diminished cognitive development, diabetes, degenerative and CVD later in life. Numerous modifiable factors decrease the risk of stunting in children. This study aimed to assess the role of the individual, household and social factors on stunting in Zimbabwean children.Design:A 1:2 unmatched case–control study.Setting:This study was conducted in two predominantly rural provinces (one with the highest national prevalence of stunting and one with the lowest prevalence) in Zimbabwe.Participants:Data were obtained from the caregivers of 150 children aged between 6 and 59 months with stunting and from the caregivers of 300 children without stunting.Results:Multiple (39) correlates of stunting were identified. Child’s age, birth length, birth weight, and weight-for-age outcome (child-related factors), caregiver’s age, maternal HIV status, occupation, and education (parental factors), breast-feeding status, number of meals, and dietary quality (dietary factors), child’s appetite, diarrhoeal and worm infection (childhood illnesses), income status, access to safe water, access to a toilet, health clubs and maternal support in infant feeding (household, socio-cultural factors) were all found to be significant predictors of childhood stunting.Conclusion:Nearly all aspects under review from the individual-, household- to social-level factors were significantly associated with childhood stunting. These findings add to the growing body of evidence supporting the WHO stunting framework and strengthen the need to focus interventions on a multi-sectoral approach to effectively address stunting in high prevalence countries.

Abstract

Background:
Due to additional responsibilities and uncertainties during the COVID-19 pandemic, primary healthcare (PHC) workers are at increased risk of burnout.

Aim:
To determine and compare the burnout levels and related factors in PHC nurses and family physicians (FPs) during the COVID-19 pandemic.

Methods:
An online survey was delivered to PHC workers. Non-random sampling method was used. To evaluate burnout, the Maslach Burnout Inventory was used, which investigates burnout in three categories: emotional exhaustion (EE), depersonalization (DP) and reduced personal accomplishment (PA). Multivariate linear regression was used to analyze factors associated with burnout for FPs and nurses separately.

Findings:
Among the participants, 55.7% were nurses, the mean age was 42.34. FPs and nurses experienced similar levels of burnout in terms of EE. Family physicians had higher levels of low PA and DP. Based on the results of the multivariate analysis, while higher EE levels were significantly associated with unequal distribution of workload and communication problems within the Family Health Center for physicians, the unequal distribution of PPE, lack of appreciation by patients or colleagues and restrictions on work-related rights were relevant factors for nurses. Lack of appreciation and restrictions of the rights were associated with increased DP scores in both groups. Unequal distribution of workload was also associated with reduced PA among FPs.

Conclusion:
PHC physicians and nurses are affected by burnout in different ways under the conditions of the COVID-19 pandemic based on gender, socioeconomic status and working conditions. To protect the mental health of PHC workers in the next public health emergency, clarification in the organization of services, empowering PHC workers in emergency risk communication and provision of timely, adequate and free PPE is essential. It is also crucial to ensure the rights of health workers through macro policy changes especially during emergencies.
Primary care trainee nursing associates in England: a qualitative study of higher education institution perspectives

Published: January 2023

Abstract

Aim:
To explore higher education institution (HEI) perspectives on the development and implementation of trainee nursing associates (NAs) in the primary care workforce in England.

Background:
Current shortages of primary health care staff have led to innovative skill mix approaches in attempts to maintain safe and effective care. In England, a new level of nursing practice, NAs, was introduced and joined the workforce in 2019. This role was envisaged as a way of bridging the skills gap between health care assistants and registered nurses and as an alternative route into registered nursing. However, there is limited evidence on programme development and implementation of trainee NAs within primary care settings and HEI perspectives on this.

Methods:
This paper draws from a larger qualitative study of HEI perspectives on the trainee NA programme. Twenty-seven staff involved in training NAs, from five HEIs across England, were interviewed from June to September 2021. The interview schedule specifically included questions relating to primary care. Data relating to primary care were extracted and analysed using a combined framework and thematic analysis approach.

Findings:
Three themes were developed: ‘Understanding the trainee role and requirements’, ‘Trainee support in primary care’ and ‘Skills and scope of practice’. It is apparent that a more limited understanding of the NA programme requirements can lead to difficulties in accessing the right support for trainees in primary care. This can create challenges for trainees in gaining the required competencies and uncertainty in understanding what constitutes a safe scope of practice within the role for both employers and trainees. It might be anticipated that as this new programme becomes more embedded in primary care, a greater understanding will develop, support will improve and the nature and scope of this new level of practice will become clearer.

AbstractPc1 geomagnetic pulsations correspond to electromagnetic ion cyclotron (EMIC) waves in the magnetosphere and are excited there with frequencies of 0.2–5 Hz. The instantaneous longitudinal extent of Pc1 waves on the ground has not been estimated yet. In this study, we analyze the Pc1 pulsations observed at seven longitudinally‐distributed ground stations at subauroral latitudes at ∼60° magnetic latitude for 1 year from July 2018 to June 2019. The hourly occurrence rates of Pc1 pulsations at all 7 stations have a peak (14%–39.6%) in the post‐noon sector and a local minimum (4.1%–8.1%) at midnight. The average frequencies become highest (0.6–1.1 Hz) after midnight and lowest (0.3–0.5 Hz) after noon at all 7 stations. An increasing tendency of total Pc1 occurrence with respect to magnetic latitude was observed. Based on these observations, we obtained a peak of probability distribution of the instantaneous Pc1 longitudinal extent as ∼82.5° with a half maximum at ∼114°, though this probability distribution can be affected by the limitation of the number of the stations. We also made model calculations on the possible longitudinal extent using artificial random Pc1 waves with fixed extents. The comparison of the model results with the observation suggests longitudinal extent of 70°–86° comparable to the peak of probability distribution (∼82.5°). A superposed epoch analysis shows that the longitudinal extent of Pc1 waves tends to increase during recovery phase of geomagnetic storms.
