Combining rules and dialogue: exploring stakeholder perspectives on preventing sexual boundary violations in mental health and disability care organizations
Authors: Kröger Charlotte , van Baarle Eva , Widdershoven Guy , Bal Roland , Weenink Jan-Willem 
Published: May 2022

Abstract
Background
Sexual boundary violations (SBV) in healthcare are harmful and exploitative sexual transgressions in the professional–client relationship. Persons with mental health issues or intellectual disabilities, especially those living in residential settings, are especially vulnerable to SBV because they often receive long-term intimate care. Promoting good sexual health and preventing SBV in these care contexts is a moral and practical challenge for healthcare organizations.

Methods
We carried out a qualitative interview study with 16 Dutch policy advisors, regulators, healthcare professionals and other relevant experts to explore their perspectives on preventing SBV in mental health and disability care organizations. We used inductive thematic analysis to interpret our data.

Results
We found three main themes on how healthcare organizations can prevent SBV in mental health and disability care: (1) setting rules and regulations, (2) engaging in dialogue about sexuality, and (3) addressing systemic and organizational dimensions.

Conclusion
Our findings suggest that preventing SBV in mental health and disability care organizations necessitates setting suitable rules and regulations and facilitating dialogue about positive aspects of sexuality and intimacy, as well as about boundaries, and inappropriate behaviors or feelings. Combining both further requires organizational policies and practices that promote transparency and reflection, and focus on creating a safe environment. Our findings will help prevent SBV and promote sexual health in mental health and disability care organizations.

AbstractBackgroundPeople living with chronic conditions and physical disabilities face many challenges accessing healthcare services. In Lebanon, in 2020, the COVID-19 pandemic and concomitant economic crisis further exacerbated the living conditions of this segment of the population. This study explored the barriers to accessing healthcare services among people living with diabetes and lower-limb amputation during the pandemic.MethodsWe conducted semi-structured, in-depth phone interviews with users of the Physical Rehabilitation Program, offered by the International Committee of the Red Cross. We used a purposive sampling technique to achieve maximum variation. Interviews were audio-recorded, transcribed, translated, and analyzed using thematic analysis following the “codebook” approach. Transcripts were coded and grouped in a matrix that allowed the development of themes and sub-themes inductively and deductively generated.ResultsEight participants (7 males, 1 female) agreed to be interviewed and participated in the study between March and April, 2021. Barriers to healthcare services access were grouped according to five emerging themes: (1) economic barriers, included increasing costs of food, health services and medications, transportation, shortage of medications, and limited income; (2) structural barriers: availability of transportation, physical environment, and service quality and availability; (3) cultural barriers: marginalization due to their physical disabilities; favoritism in service provision; (4) personal barriers: lack of psychosocial support and limited knowledge about services; (5) COVID-19 barriers: fear of getting sick when visiting healthcare facilities, and heightened social isolation due to lockdowns and physical distancing.ConclusionThe underlying economic crisis has worsened the conditions of people living with diabetes and lower-limb amputation. The pandemic has made these individuals more vulnerable to external and contextual factors that cannot be addressed only at an individual level. In the absence of a protective legal framework to mitigate inequalities, we provide recommendations for governments and nongovernmental institutions to develop solutions for more equitable access to healthcare for this segment of the population.
Spontaneous closure of an isolated congenital perimembranous ventricular septal defect in two dogs
Authors: van de Watering Anne , Szatmári Viktor 
Published: May 2022

Abstract
Background
Though spontaneous closure of isolated congenital ventricular septal defects in humans is very common, it has been rarely reported in dogs.

Case presentation
A 4 month old Havanese dog and a 4.5 month old Chihuahua x Jack Russell terrier cross were presented for murmur evaluation to the authors’ institution. Both puppies were clinically healthy and had a loud systolic murmur on the right hemithorax. Echocardiography in both dogs revealed a small, isolated, restrictive perimembranous congenital ventricular septal defect. No echocardiographic signs of left ventricular volume overload or pulmonary hypertension were present. Re-check auscultation in both dogs revealed the absence of a murmur, and echocardiography showed no flow through the interventricular septum. In the 9 kg Havanese dog and the 4 kg mixed breed dog, spontaneous closure occurred at 13–17 months and 12–30 months, respectively.

Conclusions
In both dogs the spontaneous closure of a congenital perimembranous ventricular septal defect took place in a young adult age. The mechanism of closure remains unclear.

Published: May 2022

AbstractPlasmodium knowlesiis a zoonotic malaria parasite that has gained increasing medical interest over the past two decades. This zoonotic parasitic infection is prevalent in Southeast Asia and causes many cases with fulminant pathology. Despite several biogeographical restrictions that limit its distribution, knowlesi malaria cases have been reported in different parts of the world due to travelling and tourism activities. Here, breakthroughs and key information generated from recent (over the past five years, but not limited to) studies conducted onP. knowlesiwere reviewed, and the knowledge gap in various research aspects that need to be filled was discussed. Besides, challenges and strategies required to control and eradicate human malaria with this emerging and potentially fatal zoonosis were described.
The accumulation of Vγ4 T cells with aging is associated with an increased adaptive Vγ4 T cell response after foodborne Listeria monocytogenes infection of mice

Abstract
Background
It is generally accepted that aging has detrimental effects on conventional T cell responses to systemic infections. However, most pathogens naturally invade the body through mucosal barriers. Although mucosal sites are highly enriched in unconventional immune sentinels like γδ T cells, little is currently known about the impact of aging on unconventional mucosal T cell responses. We previously established that foodborne infection with a mouse-adapted internalin A mutant Listeria monocytogenes (Lm) generates an adaptive intestinal memory CD44hi CD27neg Vγ4 T cells capable of co-producing IL-17A and IFNγ. Therefore, we used this model to evaluate the impact of aging on adaptive Vγ4 T cell responses elicited by foodborne infection.

Results
Foodborne Lm infection of female Balb/c and C57BL/6 mice led to an increased adaptive CD44hi CD27neg Vγ4 T cell response associated with aging. Moreover, Lm-elicited CD44hi CD27neg Vγ4 T cells maintained diverse functional subsets despite some alterations favoring IL-17A production as mice aged. In contrast to the documented susceptibility of aged mice to intravenous Lm infection, mice contained bacteria after foodborne Lm infection suggesting that elevated bacterial burden was not a major factor driving the increased adaptive CD44hi CD27neg Vγ4 T cell response associated with mouse age. However, CD44hi CD27neg Vγ4 T cells accumulated in naïve mice as they aged suggesting that an increased precursor frequency contributes to the robust Lm-elicited mucosal response observed. Body mass did not appear to have a strong positive association with CD44hi CD27neg Vγ4 T cells within age groups. Although an increased adaptive CD44hi CD27neg Vγ4 T cell response may contribute to foodborne Lm resistance of C57BL/6 mice aged 19 or more months, neither anti-TCRδ or anti-IL-17A treatment impacted Lm colonization after primary infection. These results suggest that γδTCR signaling and IL-17A are dispensable for protection after primary foodborne Lm infection consistent with the role of conventional T cells during the early innate immune response to Lm.

Conclusions
Lm-elicited adaptive Vγ4 T cells appear resistant to immunosenescence and memory Vγ4 T cells could be utilized to provide protective immune functions during enteric infection of aged hosts. As such, oral immunization might offer an efficient therapeutic approach to generate unconventional memory T cells in the elderly.

Published: May 2022

Abstract
Background
Cerebrospinal fluid (CSF) provides a close representation of pathophysiological changes occurring in the central nervous system (CNS); therefore, it has been employed in pathogenesis research and biomarker development for CNS disorders. CSF obtained from valid mouse models relevant to CNS disorders can be an important resource for successful biomarker and drug development. However, the limited volume of CSF that can be collected from tiny intrathecal spaces and the technical difficulties involved in CSF sampling has been a bottleneck that has hindered the detailed analysis of CSF in mouse models.

Methods
We developed a novel chronic dural port (CDP) method without cannulation for CSF collection of mice. This method enables easy and repeated access to the intrathecal space in a free-moving, unanesthetized mouse, thereby enabling continuous long-term CSF collection with minimal tissue damage and providing a large volume of high-quality CSF from a single mouse. When combined with chemical biosensors, the CDP method allows for real-time monitoring of the dynamic changes in neurochemicals in the CSF at a one-second temporal resolution in free-moving mice. Moreover, the CDP can serve as a direct access point for the intrathecal injection of CSF tracers and drugs.

Results
We established a CDP implantation and continuous CSF collection protocol. The CSF collected using CDP was not contaminated with blood and maintained physiological concentrations of basic electrolytes and proteins. The CDP method did not affect mouse’s physiological behavior or induce tissue damage, thereby enabling a stable CSF collection for up to four weeks. The spatio-temporal distribution of CSF tracers delivered using CDP revealed that CSF metabolism in different brain areas is dynamic. The direct intrathecal delivery of centrally acting drugs using CDP enabled real-time behavioral assessments in free-moving mice.

Conclusions
The CDP method enables the collection of a large volume of high-quality CSF and direct intrathecal drug administration with real-time behavioral assessment in free-moving mice. Combined with animal models relevant to CNS disorders, this method provides a unique and valuable platform for biomarker and therapeutic drug research.
“The climate itself must have hidden some medicines”: traditional veterinary medicine of indigenous and non-indigenous campesinos of the southern Andes
Authors: Olivares Fernanda , Marchant Carla , Ibarra José Tomás 
Published: May 2022

Abstract
Background
Traditional veterinary medicine (TVM) or ethnoveterinary medicine comprises knowledge, practices, and beliefs about farm animals. Its study serves to offer ecologically and culturally appropriate strategies for the management of animals and their health in a context marked by the increased use of synthetic pharmaceuticals, social–environmental degradation, pollution, and climate change. In this study, we examine the TVM that Mapuche and non-Mapuche campesinos in the southern Andes have about the management of animals and their health. In addition, we investigate the main factors influencing the current use of TVM.

Methods
Between December 2020 and March 2021, we undertook participant observation and conducted 60 semi-structured and informal interviews with Mapuche and non-Mapuche campesinos from the Pucón and Curarrehue municipal districts in the southern Andes of Chile.

Results
We identified a set of knowledge about cycles and manifestations of nature used in planning 14 animal management practices related to a Mapuche kosmos expressed in living with respect for and in dialogue with non-human elements. On health management, we recorded knowledge about 30 plant species, whose use for different categories of wounds and parasites has the highest informant consensus factors. The use of these plant species is governed by a kosmos associated with respect and reciprocity in their gathering. Nonetheless, 70% of the campesinos interviewed prefer to use synthetic pharmaceuticals. We found that the growing use of synthetic pharmaceuticals, the processes of reduction and change in the structure of land ownership, and climate change are perceived as the main factors behind processes of assimilation of new praxis and hybridization as well as the reduction and/or loss of the use of TVM.

Conclusion
Our results reveal the presence of ethnoveterinary knowledge, practices, and beliefs that are safeguarded by Mapuche and non-Mapuche campesinos in the southern Andes. However, in the context of different social–environmental changes, it is imperative to document, visibilize, and revitalize TVM since it provides new perspectives for bioculturally diverse and sustainable animal production.
Plant trait measurement in 3D for growth monitoring
Authors: Paturkar Abhipray , Sen Gupta Gourab , Bailey Donald 
Published: May 2022

Abstract
Background
There is a demand for non-destructive systems in plant phenotyping which could precisely measure plant traits for growth monitoring. In this study, the growth of chilli plants (Capsicum annum L.) was monitored in outdoor conditions. A non-destructive solution is proposed for growth monitoring in 3D using a single mobile phone camera based on a structure from motion algorithm. A method to measure leaf length and leaf width when the leaf is curled is also proposed. Various plant traits such as number of leaves, stem height, leaf length, and leaf width were measured from the reconstructed and segmented 3D models at different plant growth stages.

Results
The accuracy of the proposed system is measured by comparing the values derived from the 3D plant model with manual measurements. The results demonstrate that the proposed system has potential to non-destructively monitor plant growth in outdoor conditions with high precision, when compared to the state-of-the-art systems.

Conclusions
In conclusion, this study demonstrated that the methods proposed to calculate plant traits can monitor plant growth in outdoor conditions.
Wheat grain width: a clue for re-exploring visual indicators of grain weight
Authors: Haghshenas Abbas , Emam Yahya , Jafarizadeh Saeid 
Published: May 2022

Abstract
Background
Mean grain weight (MGW) is among the most frequently measured parameters in wheat breeding and physiology. Although in the recent decades, various wheat grain analyses (e.g. counting, and determining the size, color, or shape features) have been facilitated, thanks to the automated image processing systems, MGW estimations have been limited to using few number of image-derived indices; i.e. mainly the linear or power models developed based on the projected area (Area). Following a preliminary observation which indicated the potential of grain width in improving the predictions, the present study was conducted to explore more efficient indices for increasing the precision of image-based MGW estimations. For this purpose, an image archive of the grains was processed, which were harvested from a 2-year field experiment carried out with 3 replicates under two irrigation conditions and included 15 cultivar mixture treatments (so the archive was consisted of 180 images including more than 72,000 grains).

Results
It was observed that among the more than 30 evaluated indices of grain size and shape, indicators of grain width (i.e. Minor & MinFeret) along with 8 other empirical indices had a higher correlation with MGW, compared with Area. The most precise MGW predictions were obtained using the Area × Circularity, Perimeter × Circularity, and Area/Perimeter indices. Furthermore, it was found that (i) grain width and the Area/Perimeter ratio were the common factors in the structure of the superior predictive indices; and (ii) the superior indices had the highest correlation with grain width, rather than with their mathematical components. Moreover, comparative efficiency of the superior indices almost remained stable across the 4 environmental conditions. Eventually, using the selected indices, ten simple linear models were developed and validated for MGW prediction, which indicated a relatively higher precision than the current Area-based models. The considerable effect of enhancing image resolution on the precision of the models has been also evidenced.

Conclusions
It is expected that the findings of the present study, along with the simple predictive linear models developed and validated using new image-derived indices, could improve the precision of the image-based MGW estimations, and consequently facilitate wheat breeding and physiological assessments.
High throughput analysis of leaf chlorophyll content in sorghum using RGB, hyperspectral, and fluorescence imaging and sensor fusion
Authors: Zhang Huichun , Ge Yufeng , Xie Xinyan , Atefi Abbas , Wijewardane Nuwan K. , Thapa Suresh 
Published: May 2022

Abstract
Background
Leaf chlorophyll content plays an important role in indicating plant stresses and nutrient status. Traditional approaches for the quantification of chlorophyll content mainly include acetone ethanol extraction, spectrophotometry and high-performance liquid chromatography. Such destructive methods based on laboratory procedures are time consuming, expensive, and not suitable for high-throughput analysis. High throughput imaging techniques are now widely used for non-destructive analysis of plant phenotypic traits. In this study three imaging modules (RGB, hyperspectral, and fluorescence imaging) were, separately and in combination, used to estimate chlorophyll content of sorghum plants in a greenhouse environment. Color features, spectral indices, and chlorophyll fluorescence intensity were extracted from these three types of images, and multiple linear regression models and PLSR (partial least squares regression) models were built to predict leaf chlorophyll content (measured by a handheld leaf chlorophyll meter) from the image features.

Results
The models with a single color feature from RGB images predicted chlorophyll content with R2 ranging from 0.67 to 0.88. The models using the three spectral indices extracted from hyperspectral images (Ration Vegetation Index, Normalized Difference Vegetation Index, and Modified Chlorophyll Absorption Ratio Index) predicted chlorophyll content with R2 ranging from 0.77 to 0.78. The model using the fluorescence intensity extracted from fluorescence images predicted chlorophyll content with R2 of 0.79. The PLSR model that involved all the image features extracted from the three different imaging modules exhibited the best performance for predicting chlorophyll content, with R2 of 0.90. It was also found that inclusion of SLW (Specific Leaf Weight) into the image-based models further improved the chlorophyll prediction accuracy.

Conclusion
All three imaging modules (RGB, hyperspectral, and fluorescence) tested in our study alone could estimate chlorophyll content of sorghum plants reasonably well. Fusing image features from different imaging modules with PLSR modeling significantly improved the predictive performance. Image-based phenotyping could provide a rapid and non-destructive approach for estimating chlorophyll content in sorghum.

Published: May 2022

Abstract
Background
Anterior cruciate ligament plays a significant role in knee joint stability. It is claimed that the incidence of knee osteoarthritis increases in individuals with anterior cruciate ligament (ACL) rupture. The aim of this study was to evaluate the knee joints reaction force in ACL rupture group compared to normal subjects.

Method
Fifteen patients with acute ACL rupture and 15 healthy subjects participated in this study. The ground reaction force (GRF) and kinematic data were collected at a sampling rate of 120 Hz during level-ground walking. Spatiotemporal parameters, joint angles, muscle forces and moments, and joint reaction force (JRF) of lower extremity were analyzed by OpenSIM software.

Results
The hip, knee and ankle joints reaction force at loading response and push-off intervals of the stance phase during walking was significantly higher in individuals with ACL rupture compared to healthy controls (p value < 0.05). Walking velocity (p value < 0.001), knee (p value = 0.065) and ankle (p value = 0.001) range of motion in the sagittal plane were significantly lower in the patients with ACL rupture compared to healthy subjects. The mean value of vertical GRF in the mid-stance, the peak of the hip adduction moment in loading response and push-off phases, the hip abductor, knee flexor and vastus intermedius part of quadriceps muscle forces were significantly higher compared to healthy subjects (p < 0.05) while vastus medialis and vastus lateralis produced significantly lower force (p < 0.001).

Conclusions
Based on results of this study, lower limb JRF was higher in those with ACL rupture compared to healthy subjects may be due to the compensatory mechanisms used by this group of subjects. An increase in knee JRF in patients with ACL rupture may be the reason for the high incidence of knee OA.
