Scientific approach and attitudes among clinically working physiotherapists in Sweden -a cross sectional survey
Authors: Eek Frida , Åsenlöf Pernilla , Stigmar Kjerstin
Published: October 2023

Background

Evidence based medicine (EBM) should be an endeavor within all healthcare professions. Knowledge and understanding of science are important prerequisites of EBM.

Objective

The aim was to examine and compare perspectives on science and perceived inhibiting and facilitating factors for the assimilation and implementation of scientific information among clinically working specialist- and non-specialist physiotherapists in Sweden.

Methods

A cross-sectional survey study was conducted via a web-based questionnaire. Clinically active physiotherapists in Sweden were invited to participate. Attitudes and perspectives were compared between physiotherapists with completed or on-going specialist training, and non-specialists.

Results

In total, 1165 physiotherapists responded to the survey (75.5%, (n = 870) women, mean age 44.8 (SD 12.1), whereof 25.5% (n = 319) with completed or ongoing specialist training). The majority of participants had a high interest in science but did not consider a general scientific approach to be applied within physiotherapy. The main perceived inhibiting factor for a clinical practice more based on scientific evidence was lack of time. Specialists had in general higher interest and ability to interpret and evaluate science, and prioritized scientific evidence to a higher extent.

Conclusion

Among respondents, a scientific approach was considered valuable within physiotherapy but not considered fully applied in practice. The higher interest and perceived ability to interpret science among specialists indicates that further education and specialist training can increase both interest and understanding of science among physiotherapists.
Spatial transcriptomics in development and disease
Authors: Zhou Ran , Yang Gaoxia , Zhang Yan , Wang Yuan
Published: October 2023

The proper functioning of diverse biological systems depends on the spatial organization of their cells, a critical factor for biological processes like shaping intricate tissue functions and precisely determining cell fate. Nonetheless, conventional bulk or single-cell RNA sequencing methods were incapable of simultaneously capturing both gene expression profiles and the spatial locations of cells. Hence, a multitude of spatially resolved technologies have emerged, offering a novel dimension for investigating regional gene expression, spatial domains, and interactions between cells. Spatial transcriptomics (ST) is a method that maps gene expression in tissue while preserving spatial information. It can reveal cellular heterogeneity, spatial organization and functional interactions in complex biological systems. ST can also complement and integrate with other omics methods to provide a more comprehensive and holistic view of biological systems at multiple levels of resolution. Since the advent of ST, new methods offering higher throughput and resolution have become available, holding significant potential to expedite fresh insights into comprehending biological complexity. Consequently, a rapid increase in associated research has occurred, using these technologies to unravel the spatial complexity during developmental processes or disease conditions. In this review, we summarize the recent advancement of ST in historical, technical, and application contexts. We compare different types of ST methods based on their principles and workflows, and present the bioinformatics tools for analyzing and integrating ST data with other modalities. We also highlight the applications of ST in various domains of biomedical research, especially development and diseases. Finally, we discuss the current limitations and challenges in the field, and propose the future directions of ST.

Graphical Abstract
CT and MR imaging of patients with a dilated right ventricle due to congenital causes and their treatment
Authors: Salgado Rodrigo , Budde Ricardo PJ , Saba Luca
Published: October 2023

A variety of both acquired and congenital conditions can significantly affect the right ventricle, with a variety of potential origins that can have substantial clinical ramifications. These conditions can range from the impact of diseases like pulmonary arterial hypertension and ischaemic heart disease to valvular deficiencies resulting in heart failure. Moreover, the right ventricle response to factors like abnormal loading conditions, and its subsequent clinical effects, are influenced by factors such as age, disease progression, potential interventions, and their immediate and long-term clinical outcomes. Therefore, a readily available and reproducible non-invasive imaging assessment can aid in diagnosing the underlying condition of a dilated right ventricle, track its evolution, and help devising the most appropriate treatment strategy and optimal timing for its implementation throughout the patient’s life.

In this review, our primary focus will be on the non-invasive imaging with CT and MR of an enlarged right ventricle resulting from congenital causes and their treatment.

Authors: Kowalska Małgorzata , Dębek Wojciech , Matuszczak Ewa
Published: October 2023

Infantile Hypertrophic Pyloric Stenosis (IHPS) is the most common cause of gastric outlet obstruction in children, usually manifesting between 2 and 6 weeks of age by non-bilious vomiting. Although the COVID-19 pandemic has dominated the world since the beginning of 2020 causing the restructuring of healthcare delivery, patients still require high-quality medical care concerning other diseases. We report a 6-week infant with confirmed COVID-19 infection, who developed mild symptoms after a successful pyloromyotomy. Our aim is to encourage other professionals not to delay the necessary treatment in asymptomatic COVID-19 patients, considering the proper use of personal protective equipment, as it may worsen the course of the underlying disease.
Novel diagrammatical analyses of turnover of patients with cancer
Authors: Gandy Rob , Warburton Christopher J , Hayes Jon , Shahgholian Azar
Published: October 2023

Background/Aims

The Inverted Nomogramma di Gandy is a diagrammatical method for evaluating staff turnover in large organisations. This exploratory research investigated whether it could be applied to cohorts of ‘active’ patients with cancer (those within the first 5 years of diagnosis) and provide additional insights into the underlying dynamics of cancer incidence and prevalence.

Methods

The Inverted Nomogramma di Gandy method was applied using relevant data for all clinical commissioning groups in England in 2017. This article details the data and results for breast and lung cancer. To evaluate the method's usefulness to healthcare practitioners, a report was circulated throughout the Cheshire and Merseyside Cancer Alliance, with readers asked to respond to a 15-item survey about their perceptions of the method and its usefulness. Results were analysed using descriptive statistics.

Results

There were wide variations in incidence and prevalence of breast and lung cancer across England. The diagram showed dispersed patterns for cancer alliances and identified the locations of individual outliers, revealing the underlying dynamics. The patterns for breast cancer and lung cancer were very different; even within the Cheshire and Merseyside Cancer Alliance there were some marked variations between locations. Survey respondents were generally neutral or positive about the method.

Conclusions

This diagrammatical method provided useful analyses that were complementary to incidence and prevalence data, and potentially useful for practitioners. Because the method uses existing available data, it could be rapidly introduced to services.
Gender and Muslim philanthropy: the role of prosociality in women’s giving intention during COVID-19
Authors: Noor Zeeshan , Schwoerer Kayla , Siddiqui Shariq
Published: October 2023

Drawing on prosocial motivation and social identity theory, this study uses an original survey (n=653) of Muslims in the United States to explore gender differences in charitable giving amongst Muslims during COVID-19. We use a series of regression models to determine the effect of gender on giving intentions to Muslims (in-group) and non-Muslims (out-group) and find evidence of gender differences. Specifically, Muslim women were more likely than Muslim men to report intentions to give to non-Muslim individuals and causes. To probe this further, we tested the mediating effect of prosocial motivation on gender and willingness to give Zakat to non-Muslim causes. The findings indicate that gender differences in Muslims’ giving intentions are driven by higher levels of prosocial motivation among Muslim women. This study contributes to the limited literature on Muslim Americans’ charitable giving by examining how gender influences Muslims’ giving intentions, more specifically in times of crisis.
Complex marital paradigms: divergence between the importance of getting married and being married
Authors: Hall Scott S. , Knox David
Published: October 2023

Marital paradigm theory (MPT) asserts that societal and cultural norms and values contribute to marital beliefs. The current research examines a tenet of MPT that marital salience – a belief about the importance of getting married – and marital centrality – a belief about the importance or weight assigned to the spousal role once married – are related but distinct concepts such that individuals can diverge in their endorsement of each (for example, highly endorse one but not the other). Data from an online, anonymous survey of 4,060 emerging adults were used to group participants into a typology of low salience-low centrality, high salience-high centrality, low salience-high centrality, and high salience-low centrality. Groups were compared across background characteristics and marital meaning beliefs. Several patterns of differences among predictors were identified and discussed in the context of how the high salience-low centrality group compared with the other groups. Overall findings were consistent with MPT.
Modeling the short wavelength infrared laser radiance reflection on the sea surface
Authors: Issa Vivian , Piché Michel , Chateauneuf Marc , Theberge Francis , McTaggart Kevin
Published: October 2023

The sea surface is a complex dynamic structure dependent on atmospheric conditions, and for which physical and chemical properties change from water to foam. Its roughness determines how the surface reflects, absorbs, and emits radiance, and depends on multiple parameters such as wind speed and direction, and foam and turbulence induced from natural waves or from object displacement. In this paper, a model description is given for laser reflection on the sea surface in open water driven by the wind. The model allows calculation of the reflected laser radiance from the sea surface toward a receiver as a function of the incoming laser radiance with a known beam intensity profile. Each subarea of the sea surface seen by one pixel of the receiver is considered as an ensemble of facets, where each facet is defined by its x and y directional slopes. The wind speed and orientation determine the probability density function of the sea surface facet slope occurrence. In this paper, we have analytically expressed the reflected radiance on the sea surface as a function of the wind speed, receiver range, receiver heading, laser position, laser output aperture, and laser incoming radiance. Using the tolerance ellipse, the reflected radiance expression was approximated, and both direct and approximated results were compared. The richness in behavior of the reflected radiance and its dependence on the geometry of the problem were studied showing the impact of the receiver position, the laser position, heading, and beam divergence.
Periodic diffractive optical element for high-density and large-scale spot array structured light projection
Authors: Zhao Yanbo , Tan Qiaofeng
Published: October 2023

Structured light projection has been widely used for depth sensing in computer vision.
Diffractive optical elements (DOEs) play a crucial role in generating
structured light projected onto objects, and spot array is a common
projection pattern. However, the primary metrics of the spot array,
including density and field of view, are restricted by the principle
of diffraction and its calculation. In this paper, a novel, to the
best of our knowledge, method is proposed to achieve high-density
periodic spot array on a large scale. Further, periodic DOEs, for the
first time, are optimized to increase the density of the spot array
without decreasing the periods of the DOE. Simulation and experimental
results of high-density and large-scale spot array structured light
projection are presented, demonstrating the effectiveness of the
proposed method.

Published: October 2023

We present what is, to our knowledge, the first detailed study of thermal and population lensing in cryogenically cooled Yb:YLF. Using a rod-shaped a-cut Yb:YLF crystal, the thermal lens strength is measured as a function of absorbed pump power for both E//a and E//c polarizations for pump power levels up to 600 W. Our experiments revealed that the thermal lensing behavior in Yb:YLF is quite asymmetric. For the E//a polarization, the thermal lens is rather strong and always converging for both horizonal and vertical axes. For the E//c configuration, thermal lensing is rather weak, and its sign could be different in different axis, and furthermore, the sign of thermal lensing is observed to be dependent on the absorbed pump power level. Simulations and detailed experimental measurements show that the observed peculiar behavior is a result of competition between the photo-elastic effect and thermo-optic effect: as their relative strength varies at different pump power levels. We have also measured the contribution of surface bulging into thermal lensing and found it to be relatively small in our crystals with un-doped end caps. Lastly, the population lensing is measured in Yb:YLF for the first time, and it is found to be quite weak as well, and the polarizability difference parameter of Yb:YLF is determined as (3 ± 1.5) x 10−34 m3.
Compressive Video via IR-Pulsed Illumination
Authors: Guzmán Felipe , Brady David , Vera Esteban , Skowronek James
Published: October 2023

We propose and demonstrate a compressive temporal imaging system based on pulsed illumination to encode temporal dynamics into the imaging sensor during exposure time. Our approach enables >10x increase in effective frame rate without increasing camera complexity. To mitigate the complexity of the inverse problem during reconstruction, we introduce two keyframes: one before and one after the coded frame. We also craft a novel deep learning architecture for improved reconstruction of the high-speed scenes. Simulation and experimental results clearly demonstrate the reconstruction of high-quality, high-speed videos from the compressed data.
Help-seeking behavior among miscarrying women with and without post-miscarriage health problems in Ghana
Authors: Essien Samuel Kwaku , Chireh Batholomew , Essien Peter Kwabena
Published: October 2023

Understanding how frequently women seek assistance after experiencing a miscarriage could potentially help address unmet needs in managing post-miscarriage health problems (PMHP). However, most studies focus primarily on the causes and effects of PMHP and neglect the influence of help-seeking behavior on PMHP. This study examined help-seeking behavior among women who have experienced a miscarriage in Ghana, whether they sought help from healthcare professionals or not, and the impact it had on post-miscarriage health problems (PMHP). The study analyzed subsample data (N = 1,843) from the 2017 Ghana maternal health survey of miscarrying women aged 15–49 years who answered questions on help-seeking after a miscarriage from 900 clusters in ten administrative regions of Ghana, using a two-stage stratified cluster probability sampling design. The study used chi-square and modified Poisson with Generalized Estimating Equations (GEE) to examine help-seeking behavior among miscarrying women in Ghana and its impact on post-miscarriage health. The PMHP prevalence was 13.5% (95% CI: 12.0–15.1). Of the 1,843 women, 76.2% (95% CI: 74.3–78.2) sought help following a miscarriage, with 73.6% receiving help from healthcare professionals, 4.6% from non-healthcare professionals, and 21.8% receiving help from both groups. Help-seeking behavior was associated with factors such as education, place of residence, marital status, distance to a health facility, and money for treatment. Women who sought help had a 3.0% (Adjusted Prevalence Ratio, (aPR = 0.97, 95% Cl: 0.95–0.99) reduced prevalence of PMHP compared to those who did not seek help after controlling for other factors. Encouraging more women to seek help following a miscarriage could play a critical role in reducing PMHP, which can substantially improve their physical well-being. This finding highlights the need for more health education programs that address potential barriers in women at higher risk of miscarriage-related complications, including those aged ≥ 31 years, from seeking help after a miscarriage.

Published: October 2023

Background

In developing countries, most women want to avoid pregnancy for two years after giving birth. However, 70% do not use contraceptives during this time. Unintended pregnancies may occur for couples who delay contraceptive use during the postpartum period. The most effective form of contraceptive methods for postpartum women is long-acting reversible contraceptive (LARC). Therefore, this study aimed to assess long-acting reversible contraceptive use and associated factors among postpartum women in Sub-Saharan Africa.

Methods

Secondary data analysis was performed using the recent Demographic and Health Surveys (DHS). Stata version 14 was used to analyze the data. A multilevel mixed-effect logistic regression model was used to identify factors associated with long-acting reversible contraceptive use. Variables with a p-value < 0.05 in the multilevel mixed-effect logistic regression model were declared significant factors associated with long-acting reversible contraceptives.

Results

The magnitude of long-acting reversible contraceptive use among postpartum women was 12.6% (95% CI: 12.3, 12.8). Women primary (aOR = 1.51; 95% CI: 1.41, 1.63) and secondary education (aOR = 1.62; 95% CI: 1.32, 1.71), media exposure (aOR = 1.73; 95% CI: 1.51, 1.85), place of delivery (aOR = 1.54; 95% CI: 1.43, 1.67), number of ANC visit; 1–3 (aOR = 2.62; 95% CI: 2.31, 2.83) and ≥4 (aOR = 3.22; 95% CI: 2.93, 3.57), received PNC (aOR = 1.34; 95%CI: 1.13, 1.58), and income level; low middle income (aOR = 2.41; 95% CI: 2.11, 2.88) and upper middle income (aOR = 1.83; 95% CI: 1.56, 1.24) were significantly associated with long-acting reversible contractive use.

Conclusion

Nearly one in 10 postpartum women used long-acting reversible contraceptives. Hence, we suggest that the concerned bodies should promote family planning messages in mass media and give the well-documented benefits of postpartum long-acting contraceptive use. Promote the integration of postpartum LARC methods into maternal health care services and give better attention to postpartum women living in low-income countries and uneducated women.
The value of utility payment history in predicting first-time homelessness
Authors: Middleton Colin D. , Boynton Kim , Lewis David , Oster Andrew M.
Published: October 2023

Homelessness is a costly and traumatic condition that affects hundreds of thousands of people each year in the U.S. alone. Most homeless programs focus on assisting people experiencing homelessness, but research has shown that predicting and preventing homelessness can be a more cost-effective solution. Of the few studies focused on predicting homelessness, most focus on people already seeking assistance; however, these methods necessarily cannot identify those not actively seeking assistance. Providing aid before conditions become dire may better prevent homelessness. Few methods exist to predict homelessness on the general population, and these methods use health and criminal history information, much of which may not be available or timely. We hypothesize that recent financial health information based on utility payment history is useful in predicting homelessness. In particular, we demonstrate the value of utility customer billing records to predict homelessness using logistic regression models based on this data. The performance of these models is comparable to other studies, suggesting such an approach could be productionalized due to the ubiquity and timeliness of this type of data. Our results suggest that utility billing records would have value for screening a broad section of the general population to identify those at risk of homelessness.

Published: October 2023

Objective

We study factors affecting neutrophil-to-lymphocyte ratio (NLR) and its changes throughout the treatment (ΔNLR) of nasopharyngeal carcinoma (NPC) underwent chemoradiotherapy (CCRT) followed by adjuvant chemotherapy (AC) and oncological outcomes including overall survival (OS) and disease-free survival (DFS).

Methods

Data from 81 NPC patients was retrospectively evaluated. NLRs were obtained from first week of CCRT (pre-CCRT), last week of CCRT (end-CCRT), and at last cycle of AC (end-AC). Pre-CCRT NLR was categorized into “low” and “high”. End-CCRT and end-AC ΔNLRs were divided into “increased” and “decreased” based on NLR at these two timepoints relative to the value at pre-CCRT. Associations between sex, age, cancer stage and NLR, ΔNLRs were investigated. OS and DFS were reported.

Results

Median NLR at pre-CCRT (2.47) was lower than NLR at end-CCRT (6.29) and end-AC (3.77) (P-value = 0.043). Advanced cancer stage associated with high pre-CCRT NLR (P-value = 0.047). Male gender was associated with "increased" end-CCRT ΔNLR, whereas male gender and age ≤51 were associated with "increased" end-AC ΔNLR. Three-year OS and DFS rates were 85.25% and 76.39%, respectively. There were no statistically significant differences observed in OS and DFS among groups categorized by pre-CCRT NLR, ΔNLRs, gender, age, and cancer stage.

Conclusions

NLR increases during NPC treatment. Advanced staging is associated with higher baseline NLR. Increased ΔNLR is associated with male gender at end-CCRT and male gender with age ≤51 years at end-AC. No relation between NLR and its dynamic change with either OS or DFS was demonstrated.

Published: October 2023

The complex network topology, deployment unfriendliness, computation cost, and large parameters, including the natural changeable environment are challenges faced by fruit detection. Thus, a Simplified network topology for fruit detection, tracking and counting was designed to solve these problems. The network used common networks of Conv, Maxpool, feature concatenation and SPPF as new backbone and a modified decoupled head of YOLOv8 as head network. At the same time, it was validated on a dataset of images encompassing strawberry, jujube, and cherry fruits. Having compared to YOLO-mainstream variants, the params of Simplified network is 32.6%, 127%, and 50.0% lower than YOLOv5n, YOLOv7-tiny, and YOLOv8n, respectively. The results of mAP@50% tested using test-set show that the 82.4% of Simplified network is 0.4%, -0.2%, and 0.2% respectively more accurate than 82.0% of YOLOv5n, 82.6% of YOLOv7-tiny, and 82.2% of YOLOv8n. Furthermore, the Simplified network is 12.8%, 17.8%, and 11.8% respectively faster than YOLOv5n, YOLOv7-tiny, and YOLOv8n, including outperforming in tracking, counting, and mobile-phone deployment process. Hence, the Simplified network is robust, fast, accurate, easy-to-understand, fewer in parameters and deployable friendly.
Making a difference: Design-driven intrapreneurship at the UN Refugee Agency
Authors: van den Broek Antonius , Koria Mikko , Saarelainen Emilia , Dunlop Connor
Published: October 2023

The UN Refugee Agency (UNHCR), a large, global organization, provides vital services and advocacy for millions of displaced persons around the world within a complex and unique mandate. To meet increasing demands in creative ways while fostering a culture of intrapreneurship, the organization has set up the Innovation Fellowship Programme, a learning initiative. This article examines how design may be used to foster intrapreneurship within large organizations. Through this single-case study we examine capabilities identified through mixed-methods within the context of an intrapreneurial process. Mapping abilities between individual vs. collective and exploration vs. exploitation dimensions enabled building a design-driven, stepwise intrapreneurial process model based on effectuation principles, recognizing the causation factors at play. Enabling structures and early, deep embeddedness of the design approaches, tools and methods have been found to enable success in developing intrapreneurial capabilities. Recognizing the importance of processes in applying design within organizations, this article maps out identified intrapreneurial capabilities to individual and collective orientations and the continuum between exploration and exploitation. Through a stepwise, design-driven process modelling, the article joins the competing logics and practices of effectuation and exploration of new opportunities with causation and the exploitation of existing resources, building on individual and collective capabilities and ambidexterity. Large, global and complex organizations have multiple challenges in suffusing design practices within their structure, capabilities and processes. While unleashing the potential of individual intrapreneurs is seen as important, the knowledge of how to create conducive structures, enable organizational processes and attend to individual capability build-up remains elusive, warranting attention. The article contributes to understanding how design can enable and enhance intrapreneurship in large global organizations through facilitating structures, developing intrapreneurial capabilities and modelling conducive processes.

Published: October 2023

A Teoria Triangular do Amor do psicólogo Robert Sternberg compreende e caracteriza os relacionamentos amorosos a partir de três componentes: paixão, intimidade e decisão/ compromisso. Este artigo tem o objetivo de apresentar propriedades psicométricas da Escala Triangular do Amor Reduzida (ETAS-R) para uma amostra de 1.380 pessoas homossexuais brasileiras (966 homens). Diferentes modelos foram testados a partir de análises exploratórias e confirmatórias e o modelo teórico original de três fatores apresentou os melhores índices de ajuste, embora a retenção fatorial e os índices de unidimensionalidade da medida tenham indicado a plausabilidade de um fator geral. As evidências apresentadas acrescentam à discussão em curso sobre a estrutura fatorial e teórica da medida e inserem os relacionamentos homoafetivos no campo de pesquisa do amor na psicologia cientifica de maneira mais robusta. Em geral, os resultados apresentaram similaridades com dados analisados em outros estudos com amostras de heterossexuais, permitindo ampliar o constructo teórico sobre o amor de Sternberg para pessoas homossexuais.

Trajectory Tracking of a Wheeled Robotic Group Connected with Virtual Spring-Damper Mesh
Authors: Wiech Jakub
Published: October 2023

The article presents the solution to the problem of trajectory tracking of a self-organized group of wheeled robots in the environment without obstacles. The group of robots is tracking a trajectory realized as following a reference point by the geometric center of the group, as well as simultaneously, reaching and maintaining a given distance between neighboring robots. The proposed method is based on virtual forces from virtual spring-damper connections between robots, which allows for the trajectory tracking of the previously self-organized group while maintaining its desired shape. The presented method of control is described in detail with the description of i-th robot dynamics and was tested numerically and experimentally. The paper presents the results of numerical tests and experimental research and ends with discussion and conclusions. The paper’s results could be expanded for applications related to robotic group trajectory tracking.

A IDEIA DE SERTÃO NA FORMAÇÃO SOCIOTERRITORIAL BRASILEIRA, E NA REGIÃO DA GUERRA DO CONTESTADO
Authors: Fraga Nilson Cesar , Bueno Victória Jandira
Published: October 2023

O artigo em questão teve como objetivo investigar o papel desempenhado pela ideia de sertão na formação socioterritorial brasileira, desde as abordagens teóricas até o mundo real, vivido por populações sertanejas no país, com destaque para a região sertaneja da Guerra do Contestado. O processo histórico-cultural de formação brasileira carrega consigo uma gama de relações no cerne das ideias atribuídas ao sertão, permitindo por meio da pesquisa dos conflitos existentes ao longo dos séculos, compreender o dinamismo de composição do território nacional. Nesse sentido, a categoria espacial de sertão oriunda a partir do olhar geográfico, propõe uma dialética entre o pensamento eurocêntrico, de expansão e domínio do espaço nacional, com o modo diametralmente oposto adotado por aqueles que foram e continuam sendo expulsos dessas terras, e que enxergam no “sertão” um sinônimo de liberdade e esperança em relação a uma sociedade que desde o início os oprime. Metodologicamente foram realizados levantamentos em bibliografias relacionadas a discussão de sertão, tanto em textos geográficos, quanto nos da sociologia, história e antropologia. Para a inserção geográfica da região sertaneja do Contestado, esta ocorreu por meio da ampla produção de Fraga, que vem estudando e geografizando a região do Contestado, desde 1994.

O objetivo deste artigo foi avaliar o Indicador de Salubridade Ambiental (ISA) das Áreas com Concentração das Doenças (ACD) dengue, chikungunya e zika no território do Distrito Sanitário Oeste (DSO) da Cidade de Natal-RN. A metodologia está dividida em duas estratégias: teórica-conceitual e operacional. A primeira etapa apresenta os principais levantamentos documentais e bibliográficos que ajudaram na reflexão e discussão sobre o processo saúde-doença, homem-ambiente e salubridade para a Geografia da Saúde. A segunda etapa aborda os procedimentos operacionais que definiram: as escalas espaciais, temporais, formulários, banco de dados e a adaptação do Indicador de Salubridade Ambiental em Áreas com Concentração de Doenças (ISA/ACD). No resultado, essa pesquisa demonstrou que o uso do Sistema de Informação Geográfica (SIG) e das técnicas de análise espacial, contribuíram na identificação e análise espacial dos lugares com condições de salubridade ambiental baixa e insalubre, que estão contidas nas áreas com casos das doenças dengue, chikungunya e zika.

O Sudeste da América do Sul apresenta complexa variabilidade climática, que acarreta no estabelecimento de anomalias positivas e negativas de precipitação. Nesse cenário, o objetivo foi identificar Regiões Homogêneas de Anomalias de Precipitação na região (1961-2020) e caracterizar suas climatologias. Aplicou-se estatística multivariada e descritiva nos dados mensais de chuva do Climatic Research Unit (CRU). Para a regionalização das anomalias das chuvas empregou-se Análise de Agrupamento Hierárquico. Após a determinação das regiões, foram elaboradas séries temporais dos totais mensais. Sequencialmente, calcularam-se as médias mensais e as normais climatológicas (1961-1990/1991-2020). Foram identificados seis clusters, sendo que as regiões 1-2 localizam-se entre 32º-40ºS; as regiões 3-4 entre 24º-32ºS; e as regiões 5-6 entre 20º-27ºS. As regiões 1-2-4-5-6 são influenciadas pela circulação regional, favorecendo a configuração de períodos secos (úmidos) no inverno (verão). As regiões 4-5-6 apresentam aspectos climatológicos característicos das monções. A região 3 não apresenta predominância de períodos secos e úmidos. A comparação das normais climatológicas mostrou predominância de maiores magnitudes entre 1991-2020. Adicionalmente, diferenças ocorreram, especialmente, durante a primavera, o verão e o outono. Os resultados contribuem para o melhor entendimento dos padrões da precipitação na região e podem servir de suporte para investigações acerca da variabilidade e mudança climática.
A ESPACIALIDADE DE FLUORETO NAS ÁGUAS SUBTERRÂNEAS DA PORÇÃO NORTE DA BACIA HIDROGRÁFICA DO RIO DAS CINZAS-PR: INDICADORES DE UMA EXTENSÃO FLUORANÔMALA E OS POTENCIAIS EFEITOS À SAÚDE BUCAL

O fluoreto possui ações preventivo-terapêuticas no controle do desenvolvimento da cárie dentária em concentrações adequadas, considerado uma importante estratégia de saúde pública, entretanto, o consumo de teores acima dos parâmetros estabelecidos pode acarretar efeitos colaterais como a fluorose dentária. O objetivo deste artigo visa ampliar o conhecimento dos teores de fluoreto em águas subterrâneas para o consumo em quatorze municípios da porção norte da bacia hidrográfica do Rio das Cinzas - PR via amostras em poços tubulares. Pela análise química e espacialização detectaram-se áreas particularmente hiperfluoradas (>0,8 mg/L) em espaços contínuos (cinturões fluoranômalos), áreas de concentração adequada (0,6 – 0,8 mg/L) e hipofluoradas (< 0,6 mg/L), áreas naturalmente ineficientes no controle da doença cárie. Conclui-se necessária vigilância das águas de abastecimento público de maneira contínua pelos órgãos responsáveis quanto aos teores de fluoreto e um olhar enfático à manifestação do efeito colateral a ele associado na população residente.

O aproveitamento de água pluvial consiste em uma tecnologia com potencial de desafogar as fontes de abastecimento pública, minimizando as problemáticas urbanas de demanda hídrica. Nesse contexto, este trabalho tem como objetivo verificar o potencial econômico e a viabilidade de implementação de sistema de aproveitamento de água pluvial em residenciais de programas sociais, em Igarassu, Pernambuco. Com isso, foi utilizado o software Netuno 4.0 para realização de simulações de captação de água pluvial, para verificar o referido potencial econômico, em que a água pluvial poderia substituir parte da demanda de água proveniente das fontes de abastecimento, visando a utilização em fins não nobres. Os resultados revelam uma relativa e possível redução no consumo de água potável e, uma consequente economia na conta de água que se torna considerável ao longo dos anos. A média do potencial anual para uso da água pluvial, para uso em fins não potáveis, pode variar de 5% a 9%, dependendo do reservatório adotado para armazenamento e da demanda per capita de água considerada. Portanto, os custos para implementação do sistema de aproveitamento de água pluvial para residenciais de Igarassu, se mostraram pertinentes, com um retorno financeiro de aproximadamente 6 a 7 anos.

O regime excepcional das chuvas pode condicionar prejuízos de ordem econômica e social, especialmente relacionados ao abastecimento humano, à produção de alimento e à geração de energia. De modo a contribuir com a compreensão da variabilidade das chuvas,  objetiva-se analisar as influências do ENOS e da ODP nos totais anuais de chuva em Goiás e no Distrito Federal, a partir dos dados pluviométricos de 40 estações da Agência Nacional de Águas (ANA) e do Instituto Nacional de Meteorologia (INMET), entre os anos hidrológicos de 1975/1976 a 2015/2016. Os dados pluviométricos foram organizados e tratados de modo a retratar a frequência absoluta dos padrões de chuva que foram relacionados com as fases do ENOS e da ODP, sendo aplicado o Teste t de Student e realizada a Análise de Variância (ANOVA) para averiguar o nível de significância estatística. Os resultados evidenciaram que houve maior frequência do padrão chuvoso durante os anos considerados neutros e na condição de El Niño durante a fase quente da ODP. Houve maior frequência do padrão seco nas regiões pluviométricas ao norte da área de estudo e na região de Jataí durante a condição de La Niña em ambas as fases da ODP.

Eucalyptus oil is a superior regional commodity in Buru Regency. In addition to the relatively high selling price, oil derived from the eucalyptus plant is needed by various industrial sectors to be used as an essential ingredient for medicine. However, when we examine the daily lives of eucalyptus oil farmers, we will find that the economic situation is quite worrying, and the socio-economic environment lags behind the workers in other sectors. If natural resources are abundant, eucalyptus oil workers should be able to have a decent life, especially amid the Covid-19 pandemic, which severely limits the social and economic space of workers. This study uses a phenomenological approach, the determination of informants using a purposive sampling technique based on predetermined criteria and determined based on the research objectives. Field findings show that farmers use physical adaptation strategies to meet production targets, negatively impacting labor and land sustainability. Excessive time and work patterns result in the emergence of physical insecurity among farmers, as well as land degradation, which endangers the survival of farmers. We propose that intensive and constant rehabilitation of production can reduce the detrimental impact of the physical approach of eucalyptus oil farmers during the pandemic, ensuring the sustainability of farmers and land.Keywords: Adaptation; Land, Farmers; Strategy
