Anti-racism training for healthcare professionals: A critically appraised topic
Authors: DAnnibale Kaitlyn , Russ Anne C. , Tierney Ryan T , Mansell Jamie L
Published: March 2022

Context There is documented presence of racism in health care, resulting in negative health outcomes for minoritized people.  While there is a focus on anti-racism and anti-bias training for providers, it is unknown whether these programs are beneficial. Therefore, the clinical question is “Does anti-racism training increase knowledge of racism in health care professionals? “ Methods PubMed was searched in July of 2021 using a specific Boolean phrase of (racism*[tiab] OR "anti racism"[tiab] OR "racism"[MeSH Terms]) AND (train*[tiab] OR educat*[tiab]) AND (("health personnel"[MeSH Terms] OR ("health*"[All Fields] AND "personnel"[All Fields]) OR "health personnel"[All Fields] OR ("healthcare"[All Fields] AND "professional"[All Fields]) OR "healthcare professional*"[tiab] OR "healthcare provider*"[tiab] OR physician*[tiab] OR "athletic trainer*"[tiab] OR "physical therapist*" OR dentist*[tiab] OR "dental hygienist*"[tiab] OR doctor*[tiab] OR "medical professional*"[tiab] OR "medical provider*"[tiab] OR nurs*[tiab] OR "physician assistant*"[tiab])).  For inclusion, a study had healthcare professionals who completed anti-racism training and self-assessment surveys providing measurable outcomes. Only articles from the previous 5 years were considered. Titles were reviewed for relevance, followed by abstract and full text, when needed. The STROBE checklist for cross-sectional studies was used for appraisal. Results The search yielded 274 articles. Of those, 259 were eliminated based on title and 12 were eliminated based on reading the full text. 3 were selected for inclusion.  The first study utilized a clinical workshop developed to decrease the likelihood of clinicians expressing bias and stereotypes in interactions with patients of color. The average Likert scale for survey items included 4.8/5 for “information relevance and delivery”, 4.8 for “introduction to culture”, and 4.7/5 for “introduction to communication”.  In the second study, cultural awareness training was aimed at increasing clinicians’ ability to provide culturally safe care using authentic personal stories. The average percentage of improvement was 27% for “attitude toward minorities”, 23.8% for “Inclusion of other in self”, and 23.8% for “interaction closeness.”  The third study deployed an 8-hour training adapted to an online setting. Results demonstrated scores of 4.5/5 for “found training valuable”, 4.3/5 for “training will improve clinical care”, and 3.9/5 for “ability to create inclusive environment post-training”. The STROBE scores for these articles were 18/22, 20/22, and 21/22. Conclusion There is consistent self-reported evidence that anti-racism training is beneficial to clinicians. It is important to note that these studies were only conducted on the provider side, there is a need for information collected from the patient’s experience post-training. Due to the consistent, limited quality of evidence, a SORT score of B is recommended.
Archaeological Research in the Našlaičiai Cemetery (Vilnius City) – Searches for the Remains of Lithuanian Partisans
Authors: Vėlius Gintautas
Published: March 2022

The article describes the archaeological research of the Našlaičiai (Orphans’) Cemetery in Vilnius carried out over the period of 2017–2020. The remains of the Lithuanian post-war partisans shot in the KGB Internal Prison between 1956 and 1963 had been searched for more than a decade. Only in 2016 the historian D. Indrišionis suggested a solid hypothesis, based on archival documents and documented facts, that the remains of the partisans could be hidden together with the bodies of the executed criminals in the Našlaičiai Cemetery, then operating in the suburbs of Vilnius. Performed archaeological research confirmed this version, and the remains of all the partisans shot in the Vilnius KGB Internal Prison during the mentioned time period were found in the cemetery. The article presents a brief history of the Našlaičiai Cemetery, analyses the archival sources and methodology used in the research, and provides a detailed description of the course and the results of the archaeological research.

Authors: White Roger J. , Olds Margie , Cadogan Angela , Betteridge Sarah , Sole Gisela
Published: March 2022

Patient-reported shoulder pain, function and psychosocial status inform physiotherapy intervention. Central nervous system sensitisation may also need to be considered. The aim of this retrospective chart review was to establish and compare patient-reported outcome measures and psychosocial factors across diagnostic categories for people with should symptoms attending two shoulder physiotherapy specialist clinics. We analysed data of 445 patients including demographics, duration of pain and patient-reported outcome measures for shoulder pain and disability, central sensitivity and psychosocial factors. The physiotherapists defined diagnostic groups following the clinical assessment. The Instability group had lower pain scores (Shoulder Pain and Disability Index) compared to the Subacromial Pain (p < 0.001) and the Stiff Shoulder (p < 0.001) groups. The Stiff Shoulder group had worse disability scores than all other groups (Subacromial Pain group, p < 0.001; Instability group, p < 0.001; Acromioclavicular group, p < 0.001; Other group, p = 0.044). The Stiff Shoulder group had higher ‘Optimal Screening for Prediction of Outcome’ scores (pain associated psychological distress) than the Instability group (p = 0.040). The two-item ‘Pain Self-efficacy Questionnaire’ scores were lower for the Other group than for the Subacromial Pain group (p = 0.035). Physiotherapists should screen psychosocial factors as part of their assessment of patients with shoulder pain, regardless of diagnostic category.
Subacromial bursitis and shoulder pain: Exploring the predictors for a negative anaesthetic response
Authors: Betteridge Sarah , Cadogan Angela , Devan Hemakumar
Published: March 2022

The aim of this retrospective cross-sectional study was to (1) investigate the association between the presence of subacromial bursal pathology and response to subacromial anaesthetic injection; (2) identify variables that are predictive of a negative anaesthetic response; and (3) calculate diagnostic accuracy of these predictors. A total of 208 people with shoulder pain referred from primary care received an ultrasound guided local anaesthetic injection into the subacromial bursa following standardised clinical examination. Pain was recorded on a visual analogue scale immediately prior to and within 15 min post-anaesthetic injection. No difference in pain reduction post injection was found between those with and without bursal pathology (p < 0.05). Five potential predictors of a negative anaesthetic response were identified, but did not reach statistical significance. Clusters of three of the five predictors (high occupational shoulder demands; high or low sport/recreational shoulder demands; no current history of night pain; loss of passive external rotation range of motion of more than 30° and shoulder pain reproduced on cervical spine testing) may have clinical relevance despite not reaching statistical significance. Use of a cluster of any three predictors results in post-test probability of 93% (pre-test probability 69%). The identified predictors may inform clinical decisions regarding the use of injection therapy in those with bursal pathology observed with ultrasound and therefore potentially reduce unnecessary and costly healthcare utilisation.

Published: March 2022

The objective of this study was to quantify physical activity undertaken by patients in the acute setting following elective lower limb joint replacement and determine the relationship between physical activity and hospital outcomes (length of stay [LOS] and discharge destination). This prospective observational study included 74 adults with osteoarthritis who underwent lower limb arthroplasty (total hip replacement n = 38, total knee replacement n = 36). Participants were fitted with an accelerometer and inclinometer-based device (activPAL3TM) post-operatively prior to first mobilisation for the duration of the acute hospital admission. Physical activity data collected were steps, sit-to-stand transitions and upright time (standing and stepping). The relationship between each physical activity variable and hospital outcomes was calculated using logistic regression (for discharge destination) and linear regression (for LOS). Potential confounding factors considered in multivariable models included age, sex, body mass index, Risk Assessment Prediction Tool, American Society of Anesthesiologists Score and surgical procedure. Analyses for the relationship with these outcomes used physical activity data from day two as these comprised the largest dataset for a single day. Participants’ mean (SD) age was 67 (10) years and 53% were female. Participants performed a median (IQR) of 136 (50–294) steps, 17 (11–75) transitions and 52 (32–94) upright minutes per day. All physical activity variables were significantly negatively associated with LOS (steps p = 0.016, transition p = 0.025, upright time p = 0.024). There was a significant association between discharge to inpatient rehabilitation for steps (p = 0.010) and transitions (p = 0.005).

Published: March 2022

Highly luminescent CdTe quantum dots (QDs) are the most widely used nanoparticles for making fluorescent biosensors and optoelectronic devices. In this paper, we present the successful synthesis of CdTe QDs in the aqueous phase using mercaptosuccinic acid (MSA) as a capping ligand. The CdTe QDs were formed by the reaction of the Te precursor (in TeO2) with Cd2+/MSA in solution at 80 oC for 30 min, then annealing in an autoclave at different temperatures (110 - 150 oC) and time intervals (60 - 180 min). The synthesis of QDs in water has many advantages such as the simplicity, environmental friendliness, and using cheap chemical agents, and particularly make the CdTe QDs suitabble for bioapplications because of the biocompatibility. The high quality of the synthesized CdTe QDs was confirmed by X-ray diffraction (XRD) and their optical properties. The XRD pattern shows the cubic zinc blende structure of the synthesized CdTe QDs. Additionally, the influences of the synthesis parameters, namely the annealed temperature, time to the optical properties of the obtained QDs were systematically investigated with regard to the growth rate and particle size. As a result, CdTe QDs become bigger causing the red-shifted of peaks in their absorption and photoluminescence spectra with increasing annealed temperature and time. This provides evidence for the quantum confinement effect.

Published: March 2022

The synthesis of silver doped zinc selenium nanoparticles (ZnSe:Ag NPs) in aqueous medium using mercaptopropionic acid (MPA) as a surface stabilizer was carried out with the aim of having potential applications in luminescence and medicine. The optimal percentage of Ag dopant was found to be 1 %. The luminescence properties of the ZnSe:Ag particles was initially evaluated by using UV light. The UV spectrum was used to investigate the absorption of ZnSe:Ag Nanoparticles, and the interaction of ZnSe:Ag/MPA quantum dots with amino acid was investigated to determine the biocompatibility of the particles for applying to potential applications. The results showed that the fluorescence intensity of the particles was effectively improved. The photoluminescence (PL) of quantum dots (QDs) increased significantly as the amino acid concentration increased (Poly-L-Lysine). Moreover, ZnSe:Ag nanoparticles were successfully prepared with a green method of precipitation in aqueous solutions and using MPA as a stabilizer. The X-ray photoelectron spectroscopy and fourier-transform infrared spectroscopy had proved the formation of ZnSe:Ag particles and the interaction between them and the MPA stabilizer. TEM image was used to measure the size of the ZnSe:Ag (1 %) luminescent nanoparticles synthesized by green method. Besides, the XPS spectrum shows elements present in the ZnSe:Ag nanoparticle crystals.

Published: March 2022

In the case of plane deformation, the stress-strain of the workpiece can be calculated analytically with some simplifications without losing the generality of the problem. Numerical simulation by DEFORM software  can be used to analyze most thermo-mechanical forming processes, and many heat treatment processes. The sequentially simulate each process that is to be applied to the workpiece of Constrained Grooved Pressing (CGP) plastic deformation process by finite element method allows to determine technological parameters such as pressure force, stress field, strain field and risk of failure or destruction. The stress-strain has been analyzed at the characteristic points of the plastic deformation region including on the surface, at the center of the workpiece and at the transition regions, the results are consistent with the theoretical study. The unique feature of CGP technology compared to other types of severe plastic deformation (SPD) is that the plastic deformation zone is not in a direct contact with the mold surface, but subjected to indirect forces, and has a small hydrostatic stress. The hydrostatic force and stress parameters only come into play at the end of the back elastic compression stroke. Through numerical simulation, it is possible to visually determine the state of stress and strain on the entire workpiece at all times of the stroke. Therefore, it is possible to determine the stress in the principle axis system.
A multi-parameter Generalized Farlie-Gumbel-Morgenstern bivariate copula family via Bernstein polynomial
Authors: SUSAM Selim Orhun
Published: March 2022

In this paper, we are proposing a flexible method for constructing a bivariate generalized Farlie-Gumbel-Morgenstern (G-FGM) copula family. The method is mainly developed around the function $\phi(t)$ ($t\in [0,1]$), where $\phi$ is the generator of the G-FGM copula. The proposed construction method has useful advantages. The first of which is the direct relationship between the $\phi$ function and Kendall's tau. The second advantage is the possibility of constructing a multi-parameter G-FGM copula which allows us to better harmonize empirical instruction with the model. The construction method is illustrated by three real data examples.
Pirates of the haemoglobin

Published: March 2022

Not all treasure is silver and gold; for pathogenic bacteria, iron is the most precious and the most pillaged of metallic elements. Iron is essential for the survival and growth of all life; however free iron is scarce for bacteria inside human hosts. As a mechanism of defence, humans have evolved ways to store iron so as to render it inaccessible for invading pathogens, such as keeping the metal bound to iron-carrying proteins. For bacteria to survive within humans, they must therefore evolve counters to this defence to compete with these proteins for iron binding, or directly steal iron from them. The most populous form of iron in humans is haem: a functionally significant coordination complex that is central to oxygen transport and predominantly bound by haemoglobin. Haemoglobin is therefore the largest source of iron in humans and, as a result, bacterial pathogens in critical need of iron have evolved complex and creative ways to acquire haem from haemoglobin. Bacteria of all cell wall types have the ability to bind haemoglobin at their cell surface, to accept the haem from it and transport this to the cytoplasm for downstream uses. This review describes the systems employed by various pathogenic bacteria to utilise haemoglobin as an iron source within human hosts and discusses their contribution to virulence.

Abstract Termites are known as social insects worldwide. Presently in China 473 species, 44 genera and 4 families of termites have been reported. Of them, 111 Reticulitermes species are widely spread in different zones of China. The dispersion flight season of these Chinese Reticulitermes species are usually started from February to June, but in some regions different species are distributed, sharing their boundaries and having overlapping flight seasons. These reasons become important sources of hybridization between two different heterospecific populations of termites. It was confirmed that the fertilized eggs and unfertilized eggs of some Reticulitermes termites have the capacity of cleavage. While the unfertilized eggs of R. aculabialis, R. chinensis and R. labralis cleaved normally and the only R. aculabialis unfertilized eggs develop in embryos. While, the R. flaviceps and R. chinensis were observed with their abnormal embryonic development, and not hatching of eggs parthenogenetically. They were reported more threatening to Chinese resources as they propagate with parthenogenesis, hybridization and sexual reproduction. Eggshell and macrophiles of eggs play important roles in species identification and control. Although, they are severe pests and cause a wide range of damages to wooden structures and products in homes, buildings, building materials, trees, crops, and forests in China’s Mainland.

Published: March 2022

Abstract: Mineral nutrients play an important role in the composition of seeds, influencing the germination rate and the production of vigorous seedlings, which is fundamental for the establishment of the plant stand and crop yield. This work aimed to evaluate the effect of phosphate fertilization on phosphorus (P) content and the physiological quality of seeds of wheat cultivars. A 2 × 16 split plot design was used, with two rates of P (0 and 140 kg.ha-1) and 16 wheat genotypes (cultivars BR 18, BR 23, BRS 208, BRS 254, BRS 264, BRS 404, BRS Graúna, BRS Pardela, BRS Sabiá, WT 15025, CD 118, IPR Catuara, Ocepar 14, Supera, TBIO Bandeirante and TBIO Iguaçu). The evaluation includes: first count, germination, accelerated aging, seedling emergence and length, electrical conductivity, emergence speed index, P content in seeds, and thousand-seed weight. The data of P rates and wheat genotypes were subject to analysis of variance and to the comparison of means by the F-test and Scott-Knott test, respectively. The seeds of BR 18 and Ocepar 14 showed higher physiological quality, whereas the seeds of TBIO Iguaçu, CD 118, and BRS Sabiá showed lower vigor. Phosphate fertilization provides the production of wheat seeds with higher P content and physiological quality, but it does not influence the thousand-seed weight of most wheat cultivars.

Abstract Serrasalmus maculatus is a species of piranha which, despite being abundant in a reservoir environment, has few studies related to its parasitological and diet aspects. Thus, we aimed to document the parasitic fauna and diet of the S. maculatus in a hydroelectric reservoir in Brazil. In addition, we perform two literature reviews for the Neotropical region, recording the parasitic fauna already associated with S. maculatus and the occurrence of parasite genera identified in this study parasitizing Characiformes from other aquatic systems. Thirty-one hosts were collected with gillnets, from August 2014 to September 2016. Serrasalmus maculatus had a piscivorous feeding habit and a low richness parasitic component community, including two taxa of monogeneans, Anacanthorus lepyrophallus and Mymarothecium sp.; no endohelminths were observed. Data from the literature review, together with the findings of the study, showed that S. maculatus in the Neotropical region harbors 25 helminth taxa, with the monogenean being the most prevalent parasitic group and Brazil is the country with the most reports of the parasitic genera. These findings provide information on the relationships between diet, social behavior, and parasitic fauna of S. maculatus and on the patterns of distribution and infection of the observed parasite rates.
O FRACASSO DA REFORMA ESCOLANOVISTA: ATALIBA DE OLIVEIRA INTERPRETANDO A RENOVAÇÃO ESCOLAR PAULISTA (DÉCADAS DE 1930 E 1940)
Authors: De Oliveira Marcus Aldenisson , Valdemarin Vera Teresa
Published: March 2022

Sob uma perspectiva de análise orientada por Darnton (1986), este artigo objetivou capturar as interpretações de Ataliba Antonio de Oliveira acerca do movimento da escola nova. Trata-se de um professor paulista que acompanhou e resistiu de perto e por dentro as investidas e tentativas da renovação pedagógica em curso do aparelho escolar paulista. Ao escrever mais de duas centenas de crônicas, interpretando entre outros temas as iniciativas dos escolanovistas em São Paulo,  Ataliba de Oliveira apontou os erros que caracterizaram “o fracasso da reforma escolanovista”. Após inventariar e analisar essas crônicas, este artigo buscou responder a seguinte problemática: Como Ataliba de Oliveira interpretou o movimento da escola nova e as tentativas de inserção dessa doutrina pedagógica no aparelho escolar paulista, entre as décadas de 1930 e 1940? A lógica comparativa estrutura a maior parte das crônicas e, por meio dela, revelam-se os pontos sobre os quais incidem críticas mais contundentes do autor à reforma, aos reformadores e às consequências educacionais dessas ações, bem como o padrão de trabalho que ele desejava preservar. Tomados em conjunto, os textos de Ataliba de Oliveira construíram a interpretação de que “o fracasso da reforma escolanovista” ocorreu porque os seus apologistas não souberam ler o exemplo do passado.
Evaluation of self-consolidating concrete shear strength by means of push-off test

Self-consolidating concrete (SCC) can be characterised by its flowability, stability and passing ability. Although SCC tends to have a more uniform microstructure in the concrete–reinforcement interfacial transition zone, the reduction of the nominal size and coarse aggregate content in the concrete mix may adversely affect its shear strength. Therefore, the aim of this research was to evaluate the shear strength of SCC by means of push-off tests of 45 specimens, produced with one conventional concrete and two SCC mixtures, with two different coarse aggregate contents (reference and reduced by 30%). The transverse reinforcement ratio ranged from 0.46% to 2.28%, using closed stirrups crossing the shear plane. The increase of reinforcement ratio resulted in improvements in shear strength for specimens with one, two and three stirrups, while specimens with four and five stirrups had a premature failure owing to concrete crushing near the notch. No significant difference in shear strength was identified owing to concrete type or coarse aggregate. The experimental results were also compared with codes estimates, and Eurocode 2 presented the best fit to experimental results when compared with the American code ACI 318 and the Canadian standard CSA A23.3.

Significance Statement

Hematopoietic stem cell transplant (HSCT) is a treatment for certain hematologic malignancies and immune disorders. A complication of HSCT is membranous nephropathy (MN), which results from antibodies targeting an antigen in the glomerular basement membrane (GBM). The antigen in most cases of HSCT-associated MN is not known. Laser microdissection and mass spectrometry identified a novel protein, protocadherin FAT1 (FAT1), in HSCT-associated MN. Kidney biopsy specimens showed granular staining for FAT1 along the GBM in HSCT-associated MN. Antibodies to FAT1 were detected in serum and in kidney biopsy tissue in HSCT-associated MN, but not in controls. FAT1-associated MN appears to be a unique type of MN associated with HSCT. FAT1-associated MN represents the majority of MN associated with HSCT.

Background

Membranous nephropathy (MN) is a common cause of proteinuria in patients receiving a hematopoietic stem cell transplant (HSCT). The target antigen in HSCT-associated MN is unknown.

Methods

We performed laser microdissection and tandem mass spectrometry (MS/MS) of glomeruli from 250 patients with PLA2R-negative MN to detect novel antigens in MN. This was followed by immunohistochemical (IHC)/immunofluorescence (IF) microscopy studies to localize the novel antigen. Western blot analyses using serum and IgG eluted from frozen biopsy specimen to detect binding of IgG to new 'antigen'.

Results

MS/MS detected a novel protein, protocadherin FAT1 (FAT1), in nine patients with PLA2R-negative MN. In all nine patients, MN developed after allogeneic HSCT (Mayo Clinic discovery cohort). Next, we performed MS/MS in five patients known to have allogeneic HSCT-associated MN (Cedar Sinai validation cohort). FAT1 was detected in all five patients by MS/MS. The total spectral counts for FAT1 ranged from 8 to 39 (mean±SD, 20.9±10.1). All 14 patients were negative for known antigens of MN, including PLA2R, THSD7A, NELL1, PCDH7, NCAM1, SEMA3B, and HTRA1. Kidney biopsy specimens showed IgG (2 to 3+) with mild C3 (0 to 1+) along the GBM; IgG4 was the dominant IgG subclass. IHC after protease digestion and confocal IF confirmed granular FAT1 deposits along the GBM. Lastly, Western blot analyses detected anti-FAT1 IgG and IgG4 in the eluate obtained from pooled frozen kidney biopsy tissue and in the serum of those with FAT1-asssociated MN, but not from those with PLA2R-associated MN.

Conclusions

FAT1-associated MN appears to be a unique type of MN associated with HSCT. FAT1-associated MN represents a majority of MN associated with HSCT.

FLASH-seq protocol v3
Authors: Picelli Simone
Published: March 2022

The single-cell RNA-sequencing (scRNA-seq) field has evolved tremendously since the first paper was published back in 2009. While the first methods analysed just a handful of cells, the throughput and performance rapidly increased over a very short timespan. However, it was not until the introduction of emulsion droplets methods, that the robust and reproducible analysis of thousands of cells became feasible. Despite generating data at a speed and a cost per cell that remains unmatched by full-length protocols like Smart-seq, scRNA-seq in droplets still comes with the drawback of addressing only the terminal portion of the transcripts, thus lacking the required sensitivity for comprehensively analyzing the transcriptome of individual cells. Building upon the existing Smart-seq2/3 workflows, we developed FLASH-seq (FS), a new full-length scRNA-seq method capable of detecting a significantly higher number of genes than both previous versions, requiring limited hands-on time and with a great potential for customization.
