Published: June 2022

Introduction

Early mobility (EM), initiating and advancing physical activity in the earliest days of critical illness, has been described as the most difficult component of the ABCDEF bundle to implement and coordinate. Successful implementation of EM in clinical practice requires multiple targeted implementation strategies.

Objective

Describe the associations of nurses’ EM attitudes, subjective norms, perceived behavioural control, intention, and implementation climate and leadership with self-reported and documented EM behaviour in the intensive care unit (ICU).

Design

This was a two-site, descriptive, cross-sectional study to explore nurses’ perception of the factors influencing EM adherence.

Setting

Three ICUs (medical, surgical and cardiovascular) in an academic medical centre and two ICUs (medical/surgical and cardiovascular) in a regional medical centre in middle Tennessee.

Patients

Critically ill adults.

Interventions

None.

Main outcome measures

A 34-item investigator-developed survey, Implementation Leadership Scale, and Implementation Climate Scale were administered to ICU nurses. Survey development was informed by a Theory of Planned Behavior based elicitation study and implementation science frameworks.

Results

The academic medical centre had markedly lower EM documentation. We found no difference in nurses’ EM attitudinal beliefs, social influence, facilitators, and barriers at both sites. Nurses perceived moderate social influence to perform EM similarly across sites and considerable control over their ability to perform EM. We did note site differences for implementation climate and leadership and objective EM adherence with the regional community medical centre demonstrating statistically significant relationships of implementation climate and leadership with self-report and documented EM behaviours.

Conclusions

We identified contextual differences in implementation climate and leadership influence when comparing nurse EM behaviours. Streamlined documentation, leadership advocacy for interprofessional coordination and manpower support, and multicomponent context-based implementation strategies could contribute to better EM adherence.

The use of steel flexible barriers to mitigate landslide risk on natural hillsides is becoming common in the past decade in Hong Kong. The current design approach for this kind of barrier structure involves the adoption of the hydrodynamic load model to predict dynamic impact forces, followed by non-linear structural analyses of flexible barriers using numerical programs based on the pseudo-static force method. From local design guidelines, the dynamic pressure coefficient, a critical input parameter in the hydrodynamic load model, is taken as 2.0. This empirically considers the effect of impacts from boulders up to 2.0 m in diameter. With a view to rationalising the design approach, a series of physical impact tests and numerical analyses was conducted to investigate the dynamic debris impact on flexible barriers and the resulting barrier response. The physical impact tests involved up to 9 m3 of debris resisted by a 1.5 m high steel ring-net barrier. The tests were conducted in the 28 m long large-scale flume facility at the Kadoorie Centre in Hong Kong. Numerical modelling using computer programs LS-DYNA and NIDA-MNN was conducted to analyse the dynamic response of flexible barriers with different structural forms. The study aims to evaluate the dynamic pressure coefficient and to verify the current design approach based on the suggested dynamic pressure coefficient from this study. Results indicate that a dynamic pressure coefficient of 1.0 is, in general, appropriate for design purposes if the debris comprises primarily water and fine-grained particles.

Published: June 2022

As Canada's vast Boreal Plains are extensively managed, predictive soil mapping could be used as an effective tool to generate high-resolution soil information for the region to inform sustainable resource management. This study aimed to investigate the use of multi-temporal remote sensing data and terrain derivatives to map soil types in the region. A method of constraining subgroup and great-group soil-type predictions based on the predictions at higher-order levels (great-group and order, respectively) was tested. Sentinel time series median values obtained by using Google Earth Engine were tested in combination with first- and second-order digital elevation model derivatives for use as predictor variables in the predictive models. A recursive feature selection process was implemented to reduce the number of predictor variables used in model training. Soil classes were predicted at the order, great-group, and subgroup levels and two approaches were tested. In the first approach, models were unconstrained based on previous predictions. In the second approach, models were constrained to predict only soil great-group classes that occur within the predicted soil order for a given location and similarly predict only soil subgroup classes that occur within the predicted soil great group for a given location. Determined through independent validation testing, the most probable predicted soil maps had overall accuracies ranging from 42% to 68% and kappa scores ranging from 0.33 to 0.48. Overall, the constrained models had the best performance of the approaches tested.

Feature-Based Correspondence Filtering Using Structural Similarity Index for Visual Odometry
Authors: Kenye Lhilo , Kala Rahul
Published: June 2022

The stereo correspondence problem is one of the most pre-eminent problems in a stereo vision system. With the right correspondence, a stereo vision system can help cap over diverse problems, while on the other hand, a wrong correspondence can be costly. While the performance of a feature-based correspondence approach is exceptional, the method can still produce wrong correspondences. This work presents an amalgam of feature-based and correlation-based correspondence, where the local pixels around a feature pair are compared using Structural SIMilarity index (SSIM), enhancing the correspondences, and a semantic-based filtering module, which further filters the obtained corresponding features using semantic data whenever detected in both the stereo image pair. While approaches in the literature are focused towards finding better features and their representation, the proposed approach advocates that correlation-based verification of the features can filter out bad correspondences, and in addition, aided by semantic-level filtering. These two modules establish the novelty of the work. The proposed correspondence matching algorithm is used to solve the problem of Visual Odometry to let a low-cost robot compute its pose in a novel environment. The experimental results show adequate filtering of wrong feature correspondence wherein, different environments with different lighting conditions were also considered. The proposed approach outperformed numerous state-of-the-art approaches available in the literature. The visual odometry algorithm using the proposed correspondence matching is compared against classical methods and a deep learning method, and it is observed that the proposed approach delivers lower trajectory error values in most scenarios on the KITTI dataset sequences.

Authors: Maiti Kousik , Kayal Suchandan
Published: June 2022

This paper considers the estimation of the stress-strength parameter [Formula: see text] under progressive type-II censored samples, where [Formula: see text] is the strength and [Formula: see text] is the stress follow extended Chen distribution. It is assumed that [Formula: see text] and [Formula: see text] are independent. Two cases are studied. The uniformly minimum variance unbiased estimator is derived when a common scale parameter and a common shape parameter are known. In both the cases, the maximum likelihood estimates are computed using numerical iteration technique. Sufficient conditions are derived under which the MLEs of [Formula: see text] exist and unique. The Bayes estimates with respect to the squared error loss function are evaluated using Lindley’s and MCMC methods. Interval estimates are also constructed using asymptotic and bootstrap techniques. A simulation study is carried out to compare the proposed methods. Finally, data analysis has been performed on two real-life data sets for the purpose of illustration.

Existing topographical microstructure analyses obtain information based on surface properties of the analyzed material, such as scanning electron microscopy (SEM) and atomic force microscopy (AFM). However, these methods cannot provide quantitative topographical data, such as fractal analysis. In this paper, we present the relationship between two different methods in the obtaining the fractal dimension using electrochemical impedance spectroscopy (EIS) and AFM image analysis based on statistics and behavior of roughness and porosity properties of four other coating systems obtained by RF-magnetron sputtering. Our results demonstrated that the [Formula: see text] bilayer system is the best since it presented a lower porosity–roughness percentage and means. At least one of the fractal dimension values has a nonnormal distribution. However, the hypothesis testing showed no significant difference between the medians of both method’s fractal dimension values. The correlation coefficient showed a strong relationship between the roughness and porosity properties with a typical regular distribution pattern. According to the statistical data results, researchers can use both the methods due to their outstanding data precision.

Published: June 2022

A region ℛ is a dwell region for a moving objectOif, given a threshold distancerqand duration τq, every point of ℛ remains within distancerqfromOfor at least time τq. Points within ℛ are likely to be of interest toO, so identification of dwell regions has applications such as monitoring and surveillance. We first present a logarithmic-time online algorithm to find dwell regions in an incoming stream of object positions. Our method maintains the upper and lower bounds for the radius of the smallest circle enclosing the object positions, thereby greatly reducing the number of trajectory points needed to evaluate the query. It approximates the radius of the smallest circle enclosing a given subtrajectory within an arbitrarily small user-defined factor and is also able to efficiently answer decision queries asking whether or not a dwell region exists. For the offline version of the dwell region problem, we first extend our online approach to develop the ρ-Index, which indexes subtrajectories using query radius ranges. We then refine this approach to obtain the τ-Index, which indexes subtrajectories using both query radius ranges and dwell durations. Our experiments using both real-world and synthetic datasets show that the online approach can scale up to hundreds of thousands of moving objects. For archived trajectories, our indexing approaches speed up queries by many orders of magnitude.
The Semiotics of Cooperation
Authors: Duranti Alessandro , La Mattina Nicco A.
Published: June 2022

In this article, we suggest that in starting from dialogical, interactive studies of human discourse, we can uncover properties of cooperation that have otherwise been missed or have remained underappreciated by scholars trying to account for cooperation from an evolutionary point of view or from the point of view of its mental representation (i.e., by means of collective intentions or goals). Before uncovering these properties, we argue that a distinction must be drawn between intersubjectivity, understood as an ever-present empathic sensitivity to others, and intersubjective attunement, the process of adjusting one's actions to the ever-changing contextual conditions of interaction. It is by attending to intersubjective attunement that cooperative activities are shown to be inherently vulnerable to breach, failure, and all kinds of interactional glitches, while also being open to modifications, e.g., repairs, that allow for their successful completion. Unpacking these conditions for cooperation allows us to reveal five general properties that guide its semiotic constitution, namely, sensorial access, distributed intentionality, fluctuation of attention, improvisation, and negotiable role ascription. Attention to the semiotics of cooperation across communities and within particular activities can add a sixth general property, namely, variability in how and the extent to which cooperation is acknowledged. We introduce the term cryptocooperation to describe joint activities where the cooperative role by certain participants is underrecognized and thereby remains hidden.

Published: June 2022

Over the past few decades, ammonia (NH3) is commonly used in the petrochemical and semiconductor industries. Exposed to NH3 is dangerous to life and continuous monitoring of NH3 becomes vital. Sensitive and stable ammonia gas sensors with low-power consumption have gained increasing attention. This study uses a through-silicon via (TSV) technology and atomic layer deposition (ALD) to fabricate a three-dimensional (3D) TSV-structured room temperature TiO2 gas sensor. For various NH3 concentrations, the sensor response for the 3D TiO2 gas sensor increased if the NH3 concentration is increased. In terms of the stability and the reproducibility of the 3D room temperature TiO2 NH3 gas sensor at 10 ppm NH3 gas, the sensor response is about 9.35% on average, with an inaccuracy of <± 0.8%. For various gas measurements, the sensor also exhibits good selectivity for NH3 gas. This gas sensor of good stability, reproducibility, and selectivity with low power consumption can be used in various applications.

Published: June 2022

The study was undertaken to isolate, screen, and identify actinomycetes with antimicrobial metabolites. Twenty-one composite soil samples were randomly collected from various unique agroecological niches in the Rift Valley of Ethiopia. The soil samples were serially diluted and spread on starch casein agar medium supplemented with 50 μg/ml cycloheximide and 25 μg/ml nalidixic acid. Two hundred and forty-nine (249) actinomycetes cultures were isolated and screened by cross streaking against various human pathogens. Twenty-four isolates with pronounced antimicrobial activity were selected for identification and further screening. Among the isolates, 172 (69.1%) showed antimicrobial activities against tested pathogens. The inhibition zone of the isolates ranged from 5 ± 0.31 to >40 mm during primary screening. The antimicrobial activity of the crude extracts of promising isolates showed a statistically significant difference

. aeruginosa, almost comparable to the standard drug streptomycin (24 ± 0.58 mm). Crude extract from the isolates RVE129 and RVE187 showed higher inhibition zones of 22 ± 0.6 mm and 16 ± 0.33 mm against A. niger ATCC10535, which, however, were smaller than those obtained with the standard drug amphotericin B (29 ± 0.6 mm). Twenty-four actinomycete strains with remarkable bioactivity were characterized using various cultural, morphological, physiological, and biochemical characteristics and assigned under the genus Streptomycetes. The finding of the current study indicates that Streptomyces sp. isolated from the Rift Valley of Ethiopia was found to possess a broad spectrum of bioactivity against a range of human pathogens.

Published: June 2022

Ectopic liver tissue represents a rare entity and is mostly attributed to events occurring during embryogenesis. Previous case reports documented the presence of fetal liver parenchyma within temporarily developed organs during pregnancy, such as the placenta or the umbilical cord. Moreover, the terminology of these benign findings varies from “ectopic liver” to “hepatocellular adenoma-like neoplasm” or “hepatocellular adenoma”. Ancillary tests performed on these lesions have shown positive immunohistochemical staining for hepatocellular origin marker HepPar-1. Only one recent case report comprising molecular analysis showed no beta-catenin gain-of-function mutation. We report a case of ectopic liver in one placenta of a twin pregnancy, with an updated review of literature.

Published: June 2022

This study was aimed at exploring the transmission and drug resistance characteristics of acquired immunodeficiency syndrome (AIDS) caused by human immunodeficiency virus-1 (HIV-1). The query expansion algorithm based on Candecomp Parafac (CP) decomposition was adopted to construct a data information retrieval system for semantic web and tensor decomposition. In the latent variable model based on tensor decomposition, the three elements in the triples generated feature vectors to calculate the training samples. The HIV patient data set was selected to evaluate the performance of the system, and then, the HIV gene resistance of 213 patients was retrospectively analyzed based on the electronic medical records. 43 cases showed failure of ribonucleic acid drug resistance, the ART virological failure rate was 24.43% (43/213), and one case was not reported. There was 1 case of RNA hemolysis that could not be detected. There were 50 resistant cases of nonnucleotide reverse transcriptase inhibitors (NNRTI), accounting for 29.94% (50/167), and there were 17 resistant cases of nucleotide reverse transcriptase inhibitors (NRTI), accounting for 10.18% (17/167) of all mutation cases. Among the HIV-1 strains, 19 cases failed the detection of drug resistance sites in the integrase region, and mutations in the integrase region were significantly more than those in the protease region. There were 12 types of HIV-1 strains with drug-resistant mutations. The fusion technical scheme constructed in this study showed excellent performance in medical information retrieval. In this study, the characteristics of HIV-1 of AIDS patients were analyzed from different directions, and effective treatment was performed for patients, so as to provide reference for clinical diagnosis of AIDS patients.

Published: June 2022

Allergic bronchopulmonary aspergillosis is an uncommon condition characterized by airway hypersensitivity to Aspergillus fumigatus, resulting in worsening asthma control and bronchiectasis progression. It is associated with various radiological features. Here, we describe a 53-year-old lady with atypical CT chest finding as soft tissue density masses in both lungs evaluated initially as a lung tumour. The diagnosis was particularly challenging given the history of undiagnosed asthma. Nevertheless, bronchoscopy findings of mucus impaction and blood eosinophilia redirect the clinical thinking toward ABPA. Laboratory examination showed elevated total IgE, Aspergillus fumigatus IgE, and Aspergillus niger IgE. Shortly after treatments with systemic steroids, our patient showed a symptomatic improvement. Moreover, subsequent follow-up showed a resolution of the radiological opacities.

Published: June 2022

Kidney transplantation is the ideal treatment for end-stage renal disease (ESRD). Chronic antibody-mediated rejection (CAMR) is the main cause of graft failure. Tfh and B cells are key immune cells that play important roles in CAMR. In this study, the populations of different Tfh cell phenotypes and B cell subsets in CAMR were investigated in a total of 36 patients. Based on Banff-2019, 15 patients were diagnosed with CAMR (CAMR group), 11 recipients were diagnosed with recurrent or de novo IgA nephropathy (IgAN group), and 10 patients displayed stable renal function (stable group). The Tfh and B cell subsets were analyzed by flow cytometry. The percentage and absolute number of PD-1+ICOS+Tfh cells were significantly higher in CAMR (

p
<
0.05

), as was the ratio of CD226+Tfh cells to TIGIT+Tfh cells (

p
<
0.05

). Compared with stable recipients, CAMR patients had lower naïve B cells and higher unswitched memory B cells, which were also significantly related to renal function (

p
<
0.05

). Using the logistic regression model, we concluded that the estimated glomerular filtration rate (eGFR), absolute number of PD-1+ICOS+Tfh cells, and ratio of CD226+Tfh cells to TIGIT+Tfh cells were independent risk factors for CAMR. The combination of eGFR, PD-1+ICOS+Tfh cells, and the ratio of CD226+Tfh cells to TIGIT+Tfh cells showed better diagnostic efficacy for CAMR than each single parameter. The collective findings show that monitoring different Tfh phenotypes and B cell subsets is beneficial to kidney transplant recipients and implicate the combination of eGFR, number of PD-1+ICOS+Tfh cells, and ratio of CD226+Tfh cells to TIGIT+Tfh cells as a biomarker for diagnosing CAMR. The findings may also inform new strategies to identify and treat CAMR.

Published: June 2022

In this work, we inspect and analyze a two dimensional, unsteady mixed convectional hybrid nanofluid hydromagnetic flow (Al2O3-Cu/H2O) over a convectional heated an extending/contracting surface with the influence of thermal radiation. Hybrid nanofluid (Al2O3-Cu/H2O) flows with magnetohydrodynamic and heat source or sink. Brownian motion and thermophoresis were incorporated using the Buongiorno model. Hybrid nanofluid with vol. fraction range limited to 1.5% and within the higher temperature range of 50°C to 70°C is considered for thermal conductivity and viscosity analysis. The proposed model is then converted into ODEs through similarity transformation with the help of homotopy analysis. The effect of embedded input factors on the temperature, velocity, and concentration profiles is visually demonstrated and explained. The magnetic field has inverse impact on velocity and temperature profiles. Velocity profile increases for both mixed convection and buoyancy ratio parameters. It has been noticed that the temperature profile increases with thermal radiation. For increasing values of Lewis number, the concentration of hybrid nanoparticles is considerably lowered. Moreover, we observed an increase in the concentration of hybrid nanoparticles through a destructive chemical reaction, whereas a generative chemical reaction has the reverse effect. It has been proved that skin friction is increasing function of

Published: June 2022

The minimal-degree distributed denial-of-service attack takes advantage of flaws in the adaptive mechanisms of network protocols, which could have a big impact on network service quality. It is very hard to find, has a low attack rate, and comes at a set time. Detection methods that have been used before have problems because they only use one type of detection and are not very good at identifying the object. In the end, a way to detect many sorts of minimal DDoS assaults that use deep hybrid learning is suggested. To construct multi-type limited DDoS threat data sets and mimic diverse sorts DDoS assaults and legitimate traffic in varying situations in the 5G setting, collect congestion at the networking entry and extract flow feature info are considered. From a statistical threshold and feature engineering point of view, these data sets show how many sorts of minimal DDoS assaults are there. This study aims to develop a deep hybrid learning-based multi-type low-rate DDoS attack detection solution for 5G networks which is the novel model that is recently deployed, and a hybrid deep learning algorithm was used to train the algorithm offline, and the algorithm’s performance was compared to that of the LSTM-Light GBM and LSTM-RF algorithms. The CNN-RF revealing model was then used to detect minimal DDoS assaults at the gateway, so that multiple attacks could be detected at the same time. It can identify 4 sorts of low-rate DDoS assaults like Slow-Headers, Slow-Body, Slow-Read, and Shrew assaults, in a 120-second window. The false intercept rate is 11.03 percent. This means that 96.22 percent of traffic could be found. Using the strategy suggested can help cut down on the traffic concentration of minimal DDoS attacks at the net ingress. It can also be used in real-world situations.

Published: June 2022

The patient was an 81-year-old man who had received subtotal esophagectomy for esophageal cancer reconstructed by a gastric tube via a posterior mediastinal route. He presented to our emergency room with a complaint of epigastric pain and a small amount of hematemesis. Thoracoabdominal computed tomography showed that the reconstructed gastric tube was filled fluid and had irregular wall thickening. We suspected upper gastrointestinal bleeding, and we started to treat with administration of proton pump inhibitors (PPIs) since the anemia was mild and his vitals were stable. However, his anemia was rapidly progressed to Hb 6.0 with a large amount of old blood melena. The emergency gastroscopy showed an A2 stage ulcer with active oozing at middle esophagus reconstructed by a gastric tube. Therefore, we applied thrombin spray to treat the bleeding. Fortunately, his recovery was progressing nicely with medical treatments for a week. In this study, we experienced a case in which early administration of PPIs might be a key player to prevent his medical condition worsened further.
Vascular Anomaly Associated with Ectopic Pancreas in the Pylorus
Authors: Sato Shota , Shoji Tuyoshi , Sato Hiroshi , Maruo Hirotoshi
Published: June 2022

The ectopic pancreas is a relatively rare congenital condition, defined as pancreatic tissue lacking anatomical or vascular continuity with the normal pancreatic body. The ectopic pancreas is most frequently found in the stomach, usually asymptomatic and discovered incidentally. We report the case of a 72-year-old man who was diagnosed with cancer in the gastric vestibule. Distal gastrectomy was performed, and 3 cm of the ectopic pancreas was found on the anterior surface of the pylorus intraoperatively. The gastroduodenal artery was not found by approaching the inferior border of the pancreas but by following the branches from the common hepatic artery. Posterior view CT confirmed that the GDA terminated in the ectopic pancreas. An ectopic pancreas may be associated with vascular anomalies. Clinicians must consider the possibility of vascular anomalies when operating on patients with an ectopic pancreas. If the gastroduodenal artery cannot be found intraoperatively, identification should be attempted by following the common hepatic artery.
Hyperreflective Foci in Diabetic Macular Edema with Subretinal Fluid: Association with Visual Outcomes after Anti-VEGF Treatment
Authors: Tang Lei , Luo Dawei , Qiu Qinghua , Xu Guo-Tong , Zhang Jingfa
Published: June 2022

Introduction: Objectives of the study were to describe the hyperreflective foci (HRF) on optical coherence tomography angiography in diabetic macular edema (DME) with subretinal fluid (SRF) and explore the association of HRF in the outer retina with photoreceptor integrity and visual outcomes after anti-vascular endothelial growth factor (anti-VEGF) treatment. Methods: We retrospectively reviewed 46 eyes (36 patients) with DME treated with anti-VEGF drugs. The following parameters, including best-corrected visual acuity (BCVA), central macular thickness (CMT), the height of SRF, the number of HRF in the superficial capillary plexus, deep capillary plexus, and the outer retina, as well as the integrity of external limiting membrane (ELM) and ellipsoid zone (EZ), were evaluated and compared between the baseline and after 2 monthly injections of anti-VEGF drugs. The relationship between the HRF in the outer retina and the integrity of ELM and EZ, as well as BCVA, was analyzed. Results: BCVA was significantly improved in DME after anti-VEGF treatment; however, for the subgroup of DME patients with SRF, visual acuity remained unchanged after anti-VEGF treatment (p < 0.05 vs. p = 0.375). The number of HRF (p < 0.05), CMT (p < 0.001), and SRF height (p < 0.001) were significantly reduced, accompanied with partial restoration of ELM and EZ integrity after anti-VEGF injection. The HRF in the outer retina was correlated with the final ELM (p = 0.036) and EZ (p = 0.004) status. The final BCVA was significantly better in eyes with intact ELM (p = 0.002) and EZ at final visit (p < 0.001). Conclusion: The number of HRF in outer retina was negatively associated with the microstructural restoration of ELM and EZ, as well as the visual outcome in DME patients with SRF after anti-VEGF treatment.
Aktinische Keratose: Photodynamische Therapie durch Vorbehandlung verbessern
Authors: Lehmann Percy
Published: June 2022

Background: To enhance the efficacy of photodynamic therapy (PDT) for actinic keratosis (AKs), physical and chemical pre-treatments, such as calcipotriol (CAL) have been suggested. Objectives: To compare the long-term 12-month efficacy and safety between methylaminolevulinate (MAL)-PDT and prior application of topical CAL versus conventional MAL-PDT for AKs of the scalp. Materials & Methods: Twenty patients with multiple AKs on the scalp were randomized to receive conventional PDT on one side of the scalp and CAL-assisted PDT, in which CAL was applied daily for 15 days beforehand, on the other side. Patients were evaluated for AK clearance at three, six and 12 months thereafter. Results: All 20 patients completed the study. At three months, overall AK clearance was 92.07% and 82.04% for CAL-PDT and conventional PDT, respectively (p < 0.001). Similar results were found at six and 12 months: 92.07% and 81.69% (p < 0.001), and 90.69% and 77.46% (p < 0.001) for CAL-PDT and conventional PDT, respectively. Grade I AKs showed a similar response rate for both sides (p  =  0.055) at three months and significant differences were obtained at six (p  =  0.001) and 12 months (p < 0.001) for CAL-PDT and conventional PDT. Grade II AKs showed greater improvement on the CAL-PDT side (89.55% vs 62.90%) (p < 0.001) at three months. No difference was found at six and 12 months. Conclusion: CAL-PDT proved to be safe and more effective than conventional PDT for the treatment of AKs on the scalp after 12 months. CAL pre-treatment may have enhanced the efficacy of PDT for AK treatment, however, larger trials are needed to corroborate our findings.

Coloured as a racial calegory in Soulh Africa stands for a residual element that subverts and potentially threatens the essentialist system of race classification. Differently to Brazil, where mestiço was conceived as the point at which the racial system would be transcended through the ideology of "whitening", coloured (mestiços counterpart in South Africa) was everything the essentialist system could not classify. Instead of being the foundation of nationality as mestiço in Brazil , in South Africa coloured became a compartmentalized category justas "white" and "black". However, essentialist classification cannot deal satisfactorily with that category, for coloured can potentially subvert the whole system of classification. This article attempts to show the meaning of the category in present times as well as its origin in the colonial period.

Jorge Amado, one of lhe most renowned brazilian writers, has in many of his novels focused thc afrobrazilian cult named candomblé, as it is practised in Bahia. We can say that a great deal of the more generalized ideas about bahian candomblé owe to Amado's novels their world widespread diffusion. But of course Amado's presentation of this cult is not a documentary, ethnographic report. His literary interpretation of candomblé symbolic system deserves anthopological consideration; particulary Amado's personal envolvement with lhe candomblé's world is to be studied from an anthropological point of view: though he defines himself as an atheist, Amado has taken a firm stand as a champion of the synchretim between catholic and afrobrazilian rites. This paper deals with Amado's treatment of catholic and afrobrazilian synchretism in his novels Tenda dos milagres and O sumiço da santa.
Spirit possession and cultural innovation: the case of two Japanese femane religious leaders

lt's usual to consider religion as a conservative institution. Nonetheless , this article shows that it may also have a great transfoming potential. The history of two Japanese religious founders, Miki Nakayama (1789-1887) and Nao Deguchi (1836-1918) is taken to discuss three leve is of religious experience: (I) the person' s personality reintegration level, (II) the person's social status change, and (III) this "transformed" person's chance of interfering or changing lhe sociocultural system. More than the change itself what really matters here is the possibility of change created by special states of consciousness (possession, oneiric visions, hallucinations, etc.)
Fisiopatologia da fibromialgia
Authors: Riberto Marcelo , Pato Thais Rodrigues
Published: June 2022

A fibromialgia é caracterizada por dor crônica, generalizada e pela presença de pontos dolorosos à palpação de regiões específicas do corpo. Estudos concordam quanto à concentração de pacientes na quinta década de vida, associação com o sexo feminino e fatores socioeconômicos como baixos níveis educacionais, baixa renda e estar divorciado. As hipóteses de alterações anatomopatológicas para a fisiopatologia desta síndrome foram descartadas e os achados nesses sentido foram creditados ao sedentarismo. Os mecanismos mais aceitos para o entendimento fisiopatológico da fibromialgia no momento envolvem o desequilíbrio entre a percepção dolorosa e os mecanismos de modulação dessas vias aferentes. Níveis elevados de substância P em líquor e níveis reduzidos de serotonina e seus precursores em líquor, soro e plaquetas são sugestivos desses desequilíbrios, uma vez que a substância P é mediadora das vias aferentes enquanto a serotonina medeia a inibição da dor. Outra explicação para a alteração da atividade da serotonina seria o polimorfismo dos receptores de serotonina, o que pode explicar também o agrupamento familiar desses pacientes. Alterações cerebrais em porções rostrais ao tálamo poderiam ser responsáveis pela percepção elevada de estímulos ambientais, com a conseqüente perversão de informações proprioceptivas, térmicas e táteis ou pressórica em sensações dolorosas. Finalmente, os mecanismos reducionistas de explicação fisiopatológica da fibromialgia não têm encontrado respaldo na literatura e explicações multicausais são as mais aceitas, incluindo os mecanismos psicossociais, que não foram abordados neste artigo.
Identidade, é possível esquecê-la?
Authors: Schewinsky Sandra Regina
Published: June 2022

O presente trabalho tem como objetivo uma reflexão sobre as dificuldades e sofrimentos impingidos à pessoa que apresenta prejuízos de memória, principalmente no tocante a sua identidade, em função de um acometimento mórbido cerebral que acarretou déficits cognitivos, além da instalação da Hemiplegia. Para adentrar este percurso utilizarei o referencial teórico da Psicologia Sócio-Histórica, pois o indivíduo desenvolve-se com suas peculiaridades e singularidades em um processo dialético na interação com o meio e com o outro. Será discutido porque os déficits de memória podem ser tão dramáticos, interferindo na consciência, na atividade, afetividade e identidade da pessoa. Finalmente como o atendimento de reabilitação pode facultar o processo de metamorfose da identidade do paciente.
Esclerose múltipla e exercício físico
Authors: Furtado Otávio Luis Piva da Cunha , Tavares Maria da Consolação Gomes Cunha Fernandes
Published: June 2022

A esclerose múltipla é uma doença neurológica crônica de origem desconhecida, caracterizada por lesões axonais e áreas de desmielinização do sistema nervoso central. Nessa doença, a incapacidade física e uma série de sintomas estão relacionados ao comprometimento de sistemas funcionais e ao desuso. O tratamento geralmente inclui o uso de imunomoduladores e imunossupressores, que são capazes de retardar, mas não interromper sua progressão. Nas duas últimas décadas, programas incluindo exercícios de fortalecimento muscular, exercícios aeróbios, atividades em meio aquático e ioga têm se mostrado seguros e eficazes para pessoas com esclerose múltipla. A partir de revisão bibliográfica, discutiremos essas pesquisas e seu impacto em aspectos relevantes da doença como as alterações da força muscular, fadiga, espasticidade, depressão e a reação anormal ao calor.

O conhecimento do desempenho do idoso em suas atividades é de grande importância na assistência domiciliar, pois é o que norteia os profissionais e o cuidador no monitoramento dos cuidados prestados. O objetivo deste estudo foi avaliar a evolução da independência funcional de idosos inclusos em um programa de assistência domiciliária, sob a ótica do cuidador pela Medida de Independência Funcional (MIF), em dois momentos, com intervalo de um ano entre eles. Foi realizado estudo de seguimento, no qual os dados foram obtidos pelos prontuários de 22 pacientes, que continham a avaliação da MIF nos dois momentos estudados (outubro de 2003 e outubro de 2004). Foram excluídos os prontuários que apresentaram mudança de cuidador entre as avaliações, exclusão do programa e óbito. Realizou-se análise descritiva simples e para verificar as diferenças estatísticas o teste t-pareado e teste de Wilcoxon. A associação dos resultados da MIF com as variáveis de gênero, idade e comorbidades dos idosos foram analisadas por meio do test t - pareado e correlação de Pearson. A amostra caracterizou-se por uma maioria feminina, com idade avançada e múltiplas doenças associadas. Não foram encontradas diferenças significantes entre as avaliações, das médias da MIF motor, cognitivo e total, das medianas das seis áreas e das dezoito atividades da MIF. A manutenção na atividade expressão se associou com o gênero feminino, enquanto que a atividade interação social e a área cognição com o número de comorbidades. Observou-se manutenção da independência funcional dos pacientes no período estudado. Os resultados sugerem que no período de um ano os idosos foram capazes de manter ou retardar seu declínio funcional.

O objetivo desse trabalho foi analisar quantitativamente a resposta ao tratamento dos pacientes com dor lombar crônica atendidos pela “Escola de Postura” da DMR-HCFMUSP no período de outubro de 2001 a julho 2004, usando os questionários Roland-Morris (RM) e Short Form Health Survey (SF-36). A intensidade da queixa dolorosa foi avaliada pela Escala Visual Analógica (EVA). A amostra inicial foi composta por 244 prontuários de pacientes encaminhados e avaliados para a Escola de Postura no período de outubro de 2001 a julho de 2004, tendo completado o programa 110 pacientes desse total. Algum dados referentes a estes pacientes foram coletados, tais como: diagnósticos etiológico, tempo de evolução da doença e origem do encaminhamento; dados sócio-demográficos como sexo, idade, escolaridade, estado civil, ocupação; e, também, o comparecimento aos retornos após o primeiro mês, quarto mês, e um ano a contar da avaliação inicial. Observou-se que os indivíduos que concluíram a Escola de Postura apresentaram melhora significativa nos domínios do SF-36 para Capacidade Funcional, Aspectos Físicos, Dor, Estado Geral de Saúde, Vitalidade, bem como na avaliação pela EVA e questionário RM. Não foram observados ganhos estatisticamente significantes nos domínios Aspectos Sociais, Emocionais e Saúde Mental. Cabendo ressaltar que o período de alcance da Escola de Postura, não possibilita afirmar mudanças significativas quanto a aspectos afetivo-emocionais e novas posturas em seu relacionamento social. Novos estudos, quantitativos e qualitativos devem ser realizados de maneira a oferecer subsídios á equipe multiprofissional da Escola de Postura que permitam operar mudanças e ampliar recursos terapêuticos se necessário.
A interferência dos aspectos percepto-cognitivos nas atividades de vida diária e nas atividades instrumentais de vida diária, em clientes com sequelas por lesão neurológica
Authors: Conti Juliana
Published: June 2022

Este artigo é um levantamento bibliográfico sobre a interferência dos aspectos percepto-cognitivos durante a realização das atividades de vida diária (AVDs) e atividades instrumentais de vida diária (AIVDs) em clientes com seqüelas por lesão neurológica. Com o objetivo de indicar o quanto esses déficits interferem na reabilitação do cliente e no retorno às atividades cotidianas, o artigo mostra que essas atividades — que aparentemente são simples e já conhecidas por eles — têm de ser aprendidas outra vez. Por outro lado, o artigo revela que não apenas esses aspectos interferem nessas tarefas durante o tratamento e no final dele (no qual o cliente apresentará uma maior ou menor independência), mas também há fatores — como os motores, emocionais, culturais, sociais, econômicos e principalmente a família — que influenciarão de maneira positiva ou negativa o cliente e seu processo de reabilitação. Para ilustrar esta pesquisa, foram apresentados três casos clínicos atendidos no serviço de Terapia Ocupacional.

A disfunção motora mais evidente do acidente vascular encefálico (AVE) é a hemiparesia. Os pacientes hemiparéticos apresentam uma tendência em manter-se em uma posição de assimetria postural. O objetivo deste trabalho foi avaliar e tratar as alterações posturais em um paciente portador de hemiparesia após um acidente vascular encefálico utilizando a técnica de Reeducação Postural Global (RPG). O participante foi um paciente hemiparético à direita, devido a um AVE há cinco anos, com boa cognição segundo o Mini Exame do Estado Mental e comprometimento motor moderado. Para avaliação postural foi utilizado o software Fisiologic. Foram aplicadas dez sessões com a técnica de RPG durante oito semanas. Embora o tratamento tenha sido enfatizado na inclinação pélvica e posicionamento da escápula os resultados apresentaram evoluções também quanto à base de apoio e segundo o relato do paciente, melhora no equilíbrio e na marcha. Concluiu-se que a técnica de RPG proporcionou resultados positivos em relação ao padrão postural do paciente hemiparético.
