Background

Although there is growing demand for hospice care in China due to its aging population and increasing cancer rates, the sector remains slow to expand. Oncology nurses are the primary providers of hospice care, but little is known about their behaviors towards hospice care and related factors.

Methods

This cross-sectional study conveniently sampled 933 oncology nurses from six grade A tertiary hospitals in Hubei Province between January to March 2022. The questionnaire was composed of seven parts: general information (including sociodemographic and work-related information), hospice care behaviors, hospice care knowledge, hospice care attitudes, hospice care self-efficacy, hospice care outcome expectancy, and hospice care environment. Data were analyzed using descriptive analysis, independent sample t-tests, one-way ANOVA, Pearson’s correlation, multiple linear regression, random forest regression, and BP neural network model analysis.

Results

A total of 852 questionnaires were valid. The mean score of hospice care behaviors was 50.47 ± 10.56, with a mean item score of 3.61 ± 0.75. The three highest scoring behaviors were “pain assessment of patients (4.21 ± 0.91)”, “satisfying the physical and mental needs of dying patients (4.04 ± 0.92)”, and “creating good relationships between the medical staff and family members (4.02 ± 0.87)”. The two lowest-scoring behaviors were “proactively recommending medical institutions for hospice care to terminally ill patients and their families (2.55 ± 1.10)” and “proactively talking to patients and families about death-related topics for patients who are critically ill and cannot be reversed (2.87 ± 1.03).” Multiple linear regression, random forest regression, and BP neural network models all showed that the frequency of sharing hospice care experiences with colleagues, hospice care attitudes, hospice care self-efficacy, and hospice care environments were positively associated with hospice care behaviors.

Conclusions

The frequency of hospice care behaviors among Chinese oncology nurses is generally at a moderate to high level. The results provide a basis for promoting hospice care behaviors among oncology nurses in order to improve the quality of life for terminally ill cancer patients.
Endothelial and mural laminin-α5 contributes to neurovascular integrity maintenance
Authors: Nirwane Abhijit , Kang Minkyung , Adithan Aravinthan , Maharaj Vrishni , Nguyen Felicia , Santaella Aguilar Elliot , Nasrollahi Ava , Yao Yao
Published: February 2024

Background

Laminin-α5, a major component of the basal lamina, is predominantly synthesized by endothelial and mural cells (pericytes and vascular smooth muscle cells) in the CNS. Loss of laminin-α5 in either population fails to induce any abnormalities due to functional redundancy. Thus, the functional significance of laminin-α5 in neurovascular integrity remains unknown. Here, we hypothesize that ablation of laminin-α5 in both endothelial and mural cells increases neurovascular permeability.

Methods

The compound knockout mice were generated by crossing laminin-α5 floxed mice with Tie2-Cre and PDGFRβ-Cre, which target endothelial cells and mural cells, respectively. Neurovascular permeability in these mutants was determined with both exogenous and endogenous tracers. Endothelial paracellular and transcellular permeability was assessed by examining the expression of tight junction proteins and transcytosis-associated proteins. In addition, transmission electron microscopy (TEM) was used to visualize tight junction ultrastructure and endothelial caveolae vesicles. Defects in pericytes and astrocytes were investigated by examining pericyte coverage/contact and astrocyte polarity.

Results

Elevated neurovascular permeability was observed in the mutants. Subsequent studies found increased Caveolin-1 and decreased major facilitator superfamily domain-containing protein 2a (MFSD2A) expression, but unaltered Claudin-5 or zonula occludens-1 (ZO-1) expression. Consistent with these results, mutant mice exhibited increased endothelial caveolae vesicle number with intact tight junction structure under TEM. Additionally, pericyte coverage and contact were also decreased in the mutant mice, while astrocyte polarity was unaffected.

Conclusions

These results strongly indicate that endothelial and mural cell-derived laminin-α5 actively maintains neurovascular integrity via the transcellular rather than paracellular mechanism.

Published: February 2024

The operative mechanisms and advantageous synergies existing between the rhizobiome and the wild plant species Abutilon fruticosum were studied. Within the purview of this scientific study, the reservoir of genes in the rhizobiome, encoding the most highly enriched enzymes, was dominantly constituted by members of phylum Thaumarchaeota within the archaeal kingdom, phylum Proteobacteria within the bacterial kingdom, and the phylum Streptophyta within the eukaryotic kingdom. The ensemble of enzymes encoded through plant exudation exhibited affiliations with 15 crosstalking KEGG (Kyoto Encyclopaedia of Genes and Genomes) pathways. The ultimate goal underlying root exudation, as surmised from the present investigation, was the biosynthesis of saccharides, amino acids, and nucleic acids, which are imperative for the sustenance, propagation, or reproduction of microbial consortia. The symbiotic companionship existing between the wild plant and its associated rhizobiome amplifies the resilience of the microbial community against adverse abiotic stresses, achieved through the orchestration of ABA (abscisic acid) signaling and its cascading downstream effects. Emergent from the process of exudation are pivotal bioactive compounds including ATP, D-ribose, pyruvate, glucose, glutamine, and thiamine diphosphate. In conclusion, we hypothesize that future efforts to enhance the growth and productivity of commercially important crop plants under both favorable and unfavorable environmental conditions may focus on manipulating plant rhizobiomes.
An FSCEEMD method for downhole weak SNR signal extraction of near-bit attitude parameters
Authors: Mao Yanhui , Yang Longhan , Huo Aiqing , Li Fei , Gao Yi
Published: February 2024

In practice, the near-bit drilling tool confronts with strong vibrations and high-speed rotation. Therein the original signal amplitude of the tool attitude measurements is relatively feeble, and the signal-to-noise ratio (SNR) is exceptionally low. To handle this issue, this paper proposes a weak SNR signal extraction method, frequency selecting complementary ensemble empirical mode decomposition, which is based on ensemble empirical mode decomposition combining with complementary noise and frequency selecting. This method firstly adds different positive and negative pairs of auxiliary white noise to the original near-bit weak SNR signal, secondly adopts empirical mode decomposition on each pair of noise-added signals, then performs ensemble averaging on the obtained multiple sets of intrinsic mode function (IMF) to output more stable IMF of each order and set suitable weights according to designed frequency threshold, and finally reconstructs the original useful signal through weighted summing IMFs. Simulation results show that the extraction accuracy of well inclination angle ranges about ± 0.51°, and the extraction accuracy of tool face angle ranges about ± 1.35°, and meanwhile experimental results are provided compared with other advanced methods, which verifies the effectiveness of our method.
Views of German mental health professionals on the use of digital mental health interventions for eating disorders: a qualitative interview study
Authors: Mayer Gwendolyn , Lemmer Diana , Michelsen Ina , Schrader Pauline , Friederich Hans-Christoph , Bauer Stephanie
Published: February 2024

Introduction

Digital mental health interventions (DMHIs) are getting increasingly important for mental health care. In the case of eating disorders (EDs), DMHIs are still in early stages. Few studies so far investigated the views of mental health professionals for EDs on the integration of DMHIs in routine care.

Objective

To gain insights into the experiences, perspectives, and expectations of mental health professionals for EDs regarding DMHIs and to identify requirements for the future integration of DMHIs into routine care.

Methods

Semi-structured qualitative telephone interviews with 24 German mental health professionals treating patients with EDs were conducted. A content analysis following a deductive-inductive approach asked for experiences, advantages and chances, disadvantages and boundaries, desired functions and properties, target groups, and general conditions and requirements for DMHIs for patients with EDs.

Results

Only few professionals reported experiences with DMHIs besides video-based psychotherapy during the pandemic. From the therapists’ point of view, DMHIs have the potential to deliver low-threshold access for patients with EDs. Useful functionalities were seen in digital meal records, skills training, and psychoeducation. However, a stable therapeutic alliance was reported as an important prerequisite for the successful integration into care. Therapists expressed concerns in case of severe anorexia nervosa or suicidality. The participants felt to be informed inadequately on recent developments and on the evidence base of DMHIs.

Conclusions

Mental health professionals for EDs show positive attitudes towards DMHIs, however many barriers to the integration in routine care were observed. The highest potential was seen for the use of DMHIs in addition to outpatient care and in aftercare. Specific requirements for DMHIs are related to different areas of the healthcare spectrum and for the different symptom profiles in anorexia nervosa, bulimia nervosa and binge eating disorder. Targeted DMHIs are needed and appropriate especially for concepts of blended care.

The prevalence of mental disorders in adolescents has a considerable impact on daily life, restricting tasks and diminishing overall quality of life while potentially leading to stigmatization. This study aims to measure the impact of a mental health literacy intervention program, called “Bicho de 7 Cabeças” project, in b-learning format, on the increase of knowledge and the decrease of stigma in young people from Póvoa de Varzim, in Portugal. A quasi-experimental study was conducted, from November 2022 to May 2023, involving an experimental group (“Bicho de 7 Cabeças” protocol) and an active control group (informational brochures), utilizing a pre-test/post-test design. Mental Health Literacy Measure-MHLM, Mental Health Promoting Knowledge Scale-MHPK-10, Mental Illness Knowledge Schedule-MAKS, Reported and Intended Behaviour Scale-RIBS, and Community Attitudes toward People with Mental Illness-CAMI were used. A total of 504 young students from the 9th grade enroll in this study, with a mean age around 14 years old. There is a significant difference between stigma (p <.001) and knowledge (p <.001) scores at baseline and follow-up. The results of this study shows that interventions aimed at young people for the promotion of mental health literacy and stigma reduction are needed and more initiatives should be implemented in schools to address these problems.

Since its first launching, the ability of satellite Altimetry in providing reliable and accurate ocean geophysical information of the sea surface height (SSH), significant wave height (SWH), and wind speed has been proven by numerous researchers, as it was designed for observing the ocean dynamics through nadir range measurement between satellite and the sea surface. However, to achieve high level accuracy, environmental and geophysical effects on the range measurement must be accurately determined and corrected, particularly the effects from the atmospheric water vapor which can divert altimeter range up to 3–45 cm. Thus, satellite Altimetry is originally equipped with the on-board microwave radiometer to measure the water vapour content for correcting the range measurement. To our knowledge, no one has attempted to apply the on-board radiometer for atmospheric studies. In this present work, we attempt to optimize the on-board radiometer data for studying the atmosphere variability due to the El Niño–Southern Oscillation (ENSO) phenomena. We convert the on-board water vapor data into the precipitable water vapour (PWV), and we then investigate whether the derived PWV can capture the variability of ocean–atmosphere phenomena due to ENSO as accurate as the conventional Altimetry-derived sea level anomaly (SLA). Based on our analysis using the empirical orthogonal function (EOF), the results show convincing argument that Altimetry-derived PWV are reliable in examining the atmospheric fluctuation as the correlation of its primary principal component time series (PC1) with Oceanic Nino Index (ONI) is higher (0.87) than SLA (0.80). These results may reinforce the confidence in the ability of satellite Altimetry for ocean–atmospheric studies.

Published: February 2024

Background

Scleral buckling is typically implemented to repair rhegmatogenous retinal detachments (RRD) in young patients. Therefore, there is limited data on post-pars plana vitrectomy (PPV) cataract formation in this cohort. We report the rates and risk factors of cataract progression after PPV for RRD repair in young eyes.

Methods

Retrospective single-center cohort study. Medical records of patients between the ages of 15 to 45 undergoing PPV for uncomplicated RRD between 2014 and 2020 were reviewed.

Results

Twenty-eight eyes from 26 patients met inclusion criteria. Cataracts developed in 20/28 (71%) eyes after PPV. After PPV, nuclear sclerotic cataract (NSC) rates were higher in patients above 35 (65%) compared to below 35 years (18%) (p = 0.024). Cataracts developed more frequently after macula-off RRDs (88%) compared to macula-on RRDs (50%) (p = 0.044) with NSC more common in macula-off detachments (p = 0.020). At postoperative month 2, all eyes with C3F8 gas developed cataracts compared to 59% of eyes with no gas (p = 0.040).

Conclusions

Cataract formation was common and frequent after PPV. After PPV, young eyes and macula-on detachments developed cataracts less frequently than older eyes and macula-off detachments. If appropriate, a shorter acting gas tamponade should be considered in young eyes to minimize cataract formation.
A large type I right pulmonary artery to left atrium fistula: underwent successful percutaneous device closure with duct occluder—a rare case report
Authors: Vinothkumar S. P. , Mandava Satya Sahitya , Mallick Abhishek , Singhal Manphool , Rohit Manoj Kumar
Published: February 2024

Background

Pulmonary artery to left atrium fistula is an unusual structural cause of silent cyanosis. Only less than 100 cases have been reported so far. A high index of clinical suspicion and proper evaluation with bubble contrast echocardiography and cardiac computed tomography (CT) will help to detect this treatable anomaly. The advent of safer percutaneous closure methods has replaced the need for more invasive surgical closure.

Case presentation

We report an adolescent boy, who presented with long-standing cyanosis and progressive dyspnea with normal clinical cardiovascular examination. On evaluation, echocardiography and bubble contrast study revealed a large right pulmonary artery (RPA) to left atrium (LA) fistula. Cardiac CT confirmed the same with normal pulmonary venous drainage s/o a large 20 mm Type I RPA LA Fistula. He underwent successful percutaneous closure of the fistula tract with a 22 × 24 mm Cera™ duct occluder via transseptal approach uneventfully.

Conclusion

Our case enlightens the methodological approach to diagnosing this rare anomaly as well as the feasibility of percutaneous intervention in such cases as it is one of the largest fistula tracts closed percutaneously to date.
Takotsubo cardiomyopathy in India and its electrocardiography (ECG) comparison to myocardial infarction
Authors: Mishra Tanisha , Saha Rijushree , Paramasivam Ganesh
Published: February 2024

Background

Owing to the limited research on Takotsubo Cardiomyopathy (TCM) in Asia, we aim to evaluate in detail the clinical profiles, lab parameters, investigations, and major adverse cardiovascular events (MACE) seen in patients with TCM in the Indian subcontinent. Additionally, we have compared the electrocardiographic findings of patients with TCM to those of patients with myocardial infarction (MI).

Results

The average age of the patients affected was found to be 60 ± 11 years. Women (87.5%) and patients with hypertension (40%) were found to be at an increased risk of developing the syndrome. The most common presenting symptom was dyspnea (48%) following a trigger most commonly emotional (45%). ST elevation and significant T wave inversions were observed in 40% of patients with TCM. Echocardiography revealed a low left ventricular ejection fraction of 43 ± 9%. Coronary angiography was normal in 60%, the rest had mild/subcritical stenoses. The 6-month MACE was 20% and the mortality rate was 7.5%. Follow-up echocardiography of patients with TCM showed improvement in EF in 75% patients.

Conclusions

TCM was majorly seen in postmenopausal women following an emotional trigger, but a variety of other triggers were noted. T-wave inversions in TCM follow a diffuse pattern in contrast to specific leads seen in MI. Normal or subcritical stenosis in coronaries at presentation, along with a low EF which improves on follow up provide greater evidence for the diagnosis of TCM.

Published: February 2024

Aim of work

To determine the relationship between the gestational age and the (PSV, RI and PI) of the ductus arteriosus and lung maturity and to determine the effect of pregnancy-induced hypertension on these parameters.

Material and methods

A prospective cohort study was carried out, in which 90 pregnant women at gestational age 34–40 weeks were selected, 50 as a control and 40 with pregnancy-induced hypertension (PIH). They underwent measurement of ductus arteriosus (DA) (PSV, RI and PI) and observing the percentage of the development of neonatal RDS in control and PIH cases.

Results

There was a direct correlation between the PSV, PI, RI of ductus arteriosus and development of neonatal RDS. A cutoff value for GA, PSV, RI and PI for prediction of the subsequent development of RDS was determined in control ((35.7, 89.9, 0.80, 2.14), with sensitivity (71.4, 100, 85.7, 85.7%) and specificity (93, 97.7, 97.7, 93%), respectively), and PIH (35.7, 91.1, 0.80, 2.14), with sensitivity (71.4, 100, 85.7, 100%) and specificity (71.7, 100, 85.7, 100%), respectively).

Conclusions

We concluded from our study that for the detection of fetal lung maturity in fetuses of GA from 34 to 40 weeks, it is better to combine GA, PSV, RI and PI of DA to detect lung maturity in control and PIH groups to get more accurate results.
Development of an Artificial Intelligence–Based Image Recognition System for Time-Sequence Analysis of Tracheal Intubation
Authors: Wu Yu-Hwa , Huang Kun-Yi , Tseng Alex Chia-Chih
Published: February 2024

BACKGROUND:

Total intubation time (TIT) is an objective indicator of tracheal intubation (TI) difficulties. However, large variations in TIT because of diverse initial and end targets make it difficult to compare studies. A video laryngoscope (VLS) can capture images during the TI process. By using artificial intelligence (AI) to detect airway structures, the start and end points can be freely selected, thus eliminating the inconsistencies. Further deconstructing the process and establishing time-sequence analysis may aid in gaining further understanding of the TI process.

METHODS:

We developed a time-sequencing system for analyzing TI performed using a #3 Macintosh VLS. This system was established and validated on 30 easy TIs performed by specialists and validated using TI videos performed by a postgraduate-year (PGY) physician. Thirty easy intubation videos were selected from a cohort approved by our institutional review board (B-ER-107-088), and 6 targets were labeled: the lip, epiglottis, laryngopharynx, glottic opening, tube tip, and a black line on the endotracheal tube. We used 887 captured images to develop an AI model trained using You Only Look Once, Version 3 (YOLOv3). Seven cut points were selected for phase division. Seven experts selected the cut points. The expert cut points were used to validate the AI-identified cut points and time-sequence data. After the removal of the tube tip and laryngopharynx images, the durations between 5 identical cut points and sequentially identified the durations of 4 intubation phases, as well as TIT.

RESULTS:

The average and total losses approached 0 within 150 cycles of model training for target identification. The identification rate for all cut points was 92.4% (194 of 210), which increased to 99.4% (179 of 180) after the removal of the tube tip target. The 4 phase durations and TIT calculated by the AI model and those from the expert exhibited strong Pearson correlation (phase I, r = 0.914; phase II, r = 0.868; phase III, r = 0.964; and phase IV, r = 0.949; TIT, r = 0.99; all P < .001). Similar findings were obtained for the PGY’s observations (r > 0.95; P < .01).

CONCLUSIONS:

YOLOv3 is a powerful tool for analyzing images recorded by VLS. By using AI to detect the airway structures, the start and end points can be freely selected, resolving the heterogeneity resulting from the inconsistencies in the TIT cut points across studies. Time-sequence analysis involving the deconstruction of VLS-recorded TI images into several phases should be conducted in further TI research.
Pudgy mouse rib deformities emanate from abnormal paravertebral longitudinal cartilage/bone accumulations
Authors: Shapiro Frederic , Wang Jamie , Flynn Evelyn , Wu Joy Y.
Published: February 2024

The pudgy (pu/pu) mouse, caused by a recessive mutation in the Notch family Delta like-3 gene (Dll3), has severe rib, vertebral body and intervertebral disc abnormalities. Using whole-mount preparations and serial histologic sections we demonstrate: 1) localized paravertebral longitudinal cartilage/bone accumulations (PVLC/BAs) invariably associated with branched, fused and asymmetrically spaced ribs that emanate from it laterally; 2) abnormal rib formation immediately adjacent to abnormal vertebral body and intervertebral disc formation in asymmetric right/left fashion; and 3) patterns of rib deformation that differ in each mouse. Normal BALB/c embryo and age-matched non-affected pu/+ mice assessments allow for pu/pu comparisons. The Dll3 Notch family gene is involved in normal somitogenesis via the segmentation clock mechanism. Although pathogenesis of rib deformation is initially triggered by the Dll3 gene mutation, these findings of abnormal asymmetric costo-vertebral region structure imply that differing patterns cannot be attributed to this single gene mutation alone. All findings implicate a dual mechanism of malformation: the Dll3 gene mutation leading to subtle timing differences in traveling oscillation waves of the segmentation clock and further subsequent misdirection of tissue formation by altered chemical reaction-diffusion and epigenetic landscape responses. PVLC/BAs appear as primary supramolecular structures underlying severe rib malformation associated both with time-sensitive segmentation clock mutations and subsequent reactions.

Η παρούσα διατριβή ανήκει στον κλάδο της Εκπαιδευτικής Ψυχολογίας. Συγκεκριμένα, εξετάζει το ζήτημα της ψυχικής ανθεκτικότητας θεωρητικά και ερευνητικά και καταλήγει σε συγκεκριμένα αποτελέσματα και εκπαιδευτικές προεκτάσεις σχετικά με το σχολικό συγκείμενο.Αρχικά, εξετάζει την πορεία της έννοιας στον χρόνο, βασικές έρευνες που σηματοδότησαν και διαμόρφωσαν τη μελέτη της συγκεκριμένης έννοιας και τέλος, διερευνά την ψυχική ανθεκτικότητα σε σχέση με τον εκπαιδευτικό και τη σχέση εκπαιδευτικού-μαθητή. Ιδιαίτερη αναφορά γίνεται στη σημασία της ψυχικής ανθεκτικότητας των μαθητών στην περίοδο της πανδημίας covid-19 η οποία έθεσε ένα νέο και σημαντικό πρόβλημα σε ολόκληρη την ανθρωπότητα. Σε ερευνητικό επίπεδο, χρησιμοποιήθηκαν στοιχεία και μέθοδοι ποιοτικής και ποσοτικής έρευνας. Η ποσοτική έρευνα συμπεριέλαβε 576 μαθητές από 18 σχολεία του νομού Ηρακλείου αλλά και 58 εκπαιδευτικούς. Οι μαθητές απάντησαν σε ερωτηματολόγια αυτοαναφοράς σχετικά με την ψυχική τους ανθεκτικότητα, τη σχέση με τον εκπαιδευτικό του τμήματος και το κατά πόσο ένιωσαν να τους επηρεάζει η τηλεκπαίδευση στις παρέες και στο αίσθημα μοναξιάς που βίωσαν. Οι εκπαιδευτικοί των τμημάτων που έλαβαν μέρος στην έρευνα συμπλήρωσαν δικά τους ερωτηματολόγια ψυχικής ανθεκτικότητας, ενώ 13 εκπαιδευτικοί έδωσαν συνεντεύξεις αναλύοντας περισσότερο τις απόψεις και τις γνώσεις τους πάνω στο συγκεκριμένο θέμα. Πραγματοποιήθηκαν απλές και σύνθετες στατιστικές αναλύσεις λαμβάνοντας υπόψη όλες τις μεταβλητές. Μέσα από την ανάλυση των αποτελεσμάτων φάνηκε ο σπουδαίος ρόλος του εκπαιδευτικού στην ψυχική ανθεκτικότητα των παιδιών αλλά και το πώς οι μαθητές με υψηλά επίπεδα ψυχικής ανθεκτικότητας είναι σε θέση να διαχειρίζονται καλύτερα τις απρόβλεπτες και δύσκολες καταστάσεις όπως αυτές της τηλεκπαίδευσης και της απομάκρυνσης από την παρέα τους. Παράλληλα, μέσα από την ανάλυση των συνεντεύξεων φάνηκαν οι γνώσεις που κατέχουν οι εκπαιδευτικοί σε θεωρητικό επίπεδο γύρω από την έννοια της ψυχικής ανθεκτικότητας και τονίστηκε η ανάγκη τους για υποστήριξη και ενδυνάμωση στο πλαίσιο του σχολείου. Όλα αυτά τα ευρήματα υπενθυμίζουν τον ήδη γνωστό ρόλο του σχολείου και του εκπαιδευτικού στην προαγωγή της ψυχικής υγείας των μαθητών και θα πρέπει να αποτελέσουν αφορμή για την υιοθέτηση αντίστοιχων πρακτικών σε όλο το εκπαιδευτικό σύστημα και μέσα από κάθε μάθημα και όχι μόνο σε συγκεκριμένες δράσεις και παρεμβάσεις. Φυσικά, η έρευνα αυτή έχει αρκετούς περιορισμούς που αφορούν το μεθοδολογικό πλαίσιο αλλά αποτελεί μια έρευνα σε μεγάλο δείγμα μαθητών του νομού Ηρακλείου και για αυτό τον λόγο είναι σημαντική ως προς τα ευρήματα και τις προεκτάσεις της.
A study on awareness of breast cancer and breast self-examination practices among women above 35 years of age in rural areas of Wardha District, Maharashtra: a protocol
Authors: Koreti Mithila , Muntode Pramita
Published: February 2024

Background Breast cancer is a major cause of morbidity and mortality in women and a global health issue. Breast self-examination (BSE) is a recommended breast cancer screening technique that a woman can use on her own, in the privacy of her home. Hence, awareness regarding it and knowledge to identify any changes will be a boon to the early identification and promotion of treatment. This study aimed to increase awareness and educate women about breast self-examination (BSE) to facilitate the early detection of breast cancer in rural areas of Wardha District. Methods A community-based cross-sectional study was conducted on rural women in Wardha district. Women older than 35 years of age will be included in the study and assessed using a ‘pre-designed’ and ‘pre-structured’ questionnaire inquiring about their socio-demographic profile, awareness of breast cancer, and breast self-examination. Research implications Most studies show how to self-examine breasts, but awareness and knowledge regarding the subject are not well demonstrated and applied in many studies. Although we now understand that women do not always need to use a specific BSE technique, they should still be taught and encouraged to recognize breast changes. BSE for early detection of breast cancer has undergone a paradigm change or development into breast awareness. The progression towards breast awareness is a concept where a woman is familiar with her breasts so that she detects any change that might emerge and brings this to the attention of her healthcare practitioner right away, whereas BSE is monthly palpation of the breasts in a specific manner in which women are professionally taught. Early detection of breast cancer relies heavily on breast awareness, which is why it should be covered in general breast health education.
Vaiadel kuhjalava ja selle ehitamine Matsalu rahvuspargis / Constructing a haystack base in Matsalu national park
Authors: Jürgens Allan
Published: February 2024

Haymaking is a traditional craft that began to fade in the second half of the 20th century. The gradual disappearance of the traditional ways of making hay was due to the rapid development of modern agricultural techniques, which made the need for older techniques obsolete.
Before the advent of hay packers, hay was mainly stored in barns or haystacks. As barns became more common beginning in the early 20th century, haystacks were the most common way of preserving hay (photos 1, 3, 4). To help structure the haystack and prevent the bottom of the pile from rotting, it was first necessary to build a haystack base (photo 2). In the case of wetlands and flooded meadows, haystacks had to be built on tall wooden poles to protect them against flooding (photos 5, 6).
Although some descriptions of the construction of a traditional haystack have survived in the archives, there is no written information on haystack bases built on poles. Fortunately, there are some local people who still remember such haystack structures as well as some historically valuable photographs that have survived. Based on these old photos and local people’s memories, we organised a workshop on making a haystack base in Matsalu National Park, aimed at preserving and presenting the local heritage.
In this article, we will look at the haystack, and in particular at the haystack base needed to build it on. The first part of the article gives an overview of the necessity and importance of the haystack in farm and folk culture. A separate section is devoted to the construction of the haystack bed on poles. The second part of the article is an auto-ethnographic overview of a workshop on the building of a haystack base on the Kasari riverbank in the village of Kelu. Along with photographic material, the article also gives an overview of the different stages of the build and some details about the construction.

A APRENDIZAGEM DE REGRAS DO SISTEMA MATEMÁTICO ESCOLAR NA MODELAGEM MATEMÁTICA
Authors: Gomes Souza Elizabeth , Cerqueira Barbosa Jonei
Published: February 2024

Este artículo tiene como objetivo analizar el aprendizaje de las matemáticas que se constituyen en la modelización matemática en el aula, entendiendo a la modelización matemática como la organización de situaciones empíricas. Analizamos el tema a partir de la comprensión de las matemáticas como sistema normativo regido por reglas. Se trata de una comprensión desarrollada por los análisis de las delimitaciones filosóficas de Ludwig Wittgenstein y de las interpretaciones teóricas de Anna Sfard. Los discursos producidos por un grupo de alumnos y de una profesora, obtenidos mediante la observación de situaciones empíricas, fueron utilizados como material para el análisis del tema. Los usos que los alumnos y la profesora atribuyeron a las palabras nos permitieron identificar que el juego discursivo de modelización es jugado bajo las reglas instituidas en la forma de vida de las matemáticas desarrolladas en el contexto escolar.

El apoyo estadístico al área de la salud creció mucho en los últimos 50 años y continúa avanzando, principalmente después de la popularización de las computadoras y de los softwares específicos. Los términos como práctica basada en evidencias y epidemiología tienen a la estadística como uno de sus pilares y son comunes en el área de la salud. Dada su importancia, muchos esfuerzos de mejora de la enseñanza y aprendizaje de Estadística se han diseminado en el medio académico. Este trabajo muestra y analiza los caminos que la enseñanza de Estadística tomó, considerando la revisión de bibliografía hecha por Garfield (1995), retomada por Garfield y Ben-Zvi (2007) y enfocándose en el caso específico del área de la salud a través de la revisión propia la literatura, que contempló artículos publicados de 2007 a 2017 en revistas del área de la salud y de la enseñanza. La revisión propia de literatura analizó 26 artículos que se clasificaron en dos categorías: aspectos psicológicos y metodologías de enseñanza. La enseñanza de estadística evolucionó como área de estudio e investigación, los esfuerzos puntuales y particulares pasaron a contar con instrucciones y directrices institucionales específicas para la enseñanza de estadística. Sin embargo, faltan instrumentos para la evaluación de lo que los alumnos aprenden y el uso de las teorías de aprendizaje es ínfimo, lo que impacta en metodologías aún muy basadas solamente en la práctica de los profesores.

Este artículo relaciona nociones de la Matemática Educativa con la transversalidad de los saberes matemáticos en situaciones de pandemia por coronavirus. Se analiza un fenómeno social en el ámbito de la salud desde una mirada académica para la construcción de diálogos sobre las implicaciones de las acciones de política pública que la población lleva a cabo. Las reflexiones propuestas dejan ver el papel que juega el pensamiento matemático en la comprensión de la situación, las medidas de carácter preventivo y los problemas que de este se deriven; todo ello conlleva a la consideración de la noción de aula extendida. Así, el desarrollo del pensamiento habrá de entenderse más allá que la capacidad de resolución de problemas.

Introduction: Cysticercosis leads to a cyst formation known to occur due to the Taenia solium parasite. Patients normally present with seeding and formation of the cysts in the central nervous system (CNS) as neurocysticercosis (NCC). Intramuscular cysts are rare presentations and are mostly incidental findings in NCC patients. We present a rare case of a rapidly progressing isolated cysticercosis of the flexor digitorum profundus (FDP) muscle leading to a pseudotumor and presenting with pseudo-Volkmanns contracture and a positive Volkmanns sign. Case report: A 26-year-old right-hand dominant vegetarian female presented with a 3-month-old progressive swelling on her right forearm with no antecedent trauma history. A positive Volkmann’s sign was present. Radiographs were normal, and ultrasonography showed a cysticercus cyst in the FDP muscle belly with a multiseptated abscess around the tendons of the middle, ring, and little fingers at the musculotendinous junction. Bones and nerves were spared. After ruling out CNS involvement and providing oral antiparasitic cover, she underwent a successful surgical exploration with cyst excision, debridement, and freeing of the involved tendons. Immediately post-operatively, she was able to completely extend the three involved fingers without flexion at the wrist joint (resolving Volkmann’s sign). She reported significant improvements in the functions of daily life. She was protected with a splint for 2 weeks. There was no recurrence, and the swelling subsided. Histo-pathology reports depicted cysts with visible scolices. Conclusion: It is important to consider the possibility of ‘Myoparasitism’ in atraumatic cases showing contractures. Clinching the right diagnosis is essential and best done with a multidisciplinary approach with ultrasonography, magnetic resonance imaging, electromyography, and nerve conduction velocity studies. It is essential to rule out life-threatening NCC beforehand and offer prophylaxis. Surgical exploration is generally indicated to regain normal function and free the involved structures. Keywords: Volkmanns contracture, cysticercosis, pseudotumor, cyst.
Crisis management in English local government: the limits of resilience
Authors: Arrieta Tania , Davies Jonathan S.
Published: February 2024

Research on local government in the UK during the era of austerity has shown that the decisions taken by local councils to cope with financial stresses were often narrated through the discourse of ‘resilience’, referencing their capacity to innovate and transform services, while protecting service provision in core areas. This emphasis on ‘resilience’ focused on the deployment of strategies to overcome funding challenges. However, this earlier research did not question the longer-term risks, trade-offs and negative social implications associated with such decisions, and how, even in circumstances where these practices provided some ‘breathing space’, in the longer-term they risked adding even more strain to the system as a whole.

This article fills an important research gap by considering four resilience strategies of two local authorities in England: Leicester and Nottingham. These four strategies are: savings, reserves, collaboration and investment. Applying a meso-level perspective and exploring resilience through the lens of crisis management, it asks in what ways and for whom resilience generates positive, zero and negative-sum outcomes.

This research enhances our understanding of the resilience concept by reflecting on its limitations and the risks it poses for local government. It also reveals that, while the concept of ‘resilience’ has been much criticised for normalising crises and generally operating as part of a de-politicising vocabulary, research is lacking on how the practices of resilience produce positive, zero or negative-sum outcomes.

Las personas sin hogar son ciudadanos que sufren la discriminación social y legal de la sociedad. El sistema capitalista cataloga a las personas en función de su poder adquisitivo y comporta que las personas pobres queden excluidas del conjunto de la ciudadanía. La violencia estructural ejercida hacia las personas sin hogar debe erradicarse y enmarcarse dentro de un contexto de lucha por los derechos humanos básicos ya que la calidad de la democracia depende del trato que se le brinde a los colectivos más desfavorecidos. En el presente artículo se ha elegido a la ciudad de Barcelona como centro del análisis práctico debido a su importancia y dimensiones dentro de las ciudades del entorno europeo y debido a la disponibilidad de información rigurosa sobre la cantidad y distribución de recursos orientados a las personas sin hogar.
«Por qué se escribe»: Zambrano e il bordo della fenditura
Authors: Mignucci Vanessa
Published: February 2024

Partendo dall’analisi del saggio giovanile "Por qué se escribe" (1934), l’articolo intende indagare la scrittura zambraniana, mostrando come attorno ad essa gravitino e si agglutinino questioni esplicitamente percorse e ripercorse dal suo pensiero — si vedano la passivité, la solitudine, il vuoto, la parola come agente creatore — e questioni meno esplicite e meno insistite ma nondimeno interessanti e stimolanti — si vedano l’impersonale e l’identificazione come gesto agito e subito di fenditura interna/esterna al sé.
Educar para el devenir. Desarrollo de la resiliencia generativa y la mentalidad de crecimiento en la educación primaria: estrategias y buenas prácticas basadas en el currículo actual.
Authors: Montesinos Alabau Beatriz
Published: February 2024

Vivimos en un mundo que cambia aceleradamente. El transhumanismo o post humanismo, la posverdad, el auge de la inteligencia artificial, la crisis climática, etc.…, nos sitúan en un momento clave de la historia de la humanidad, con grandes desafíos y cambios complejos que no pueden ser abordados de una forma simplista.

            Ante este panorama, desde el ámbito educativo, no sabemos hacia dónde nos dirigimos exactamente, pero si hay algo por lo que podemos seguir abogando es por cuidar y cultivar en las aulas el tipo de personas y personalidades que puedan abordar estos cambios de la mejor manera posible.

           La etapa de educación primaria, junto con la etapa de educación infantil, conforman la base sobre la que se sustentan los cimientos de las personas que llegarán a ser los alumnos. Además de las destrezas y competencias instrumentales básicas que componen los currículos de estas etapas, son claves también un adecuado desarrollo socioemocional, una correcta maduración del autoconcepto y de la autoestima, así como la motivación hacia el aprendizaje a lo largo de toda la vida.

            El propósito de este artículo es desarrollar una propuesta pedagógica que incluya la resiliencia generativa y la mentalidad de crecimiento como elementos vertebradores de las competencias personales y sociales que deben adquirir los alumnos.

            Esta propuesta se basa científicamente en aquellos aspectos que la neurociencia y la psicología han aportado en los últimos años acerca del funcionamiento de nuestro cerebro. Además, curricularmente se fundamenta en los descriptores operativos de las competencias clave que definen el perfil de salida del alumnado cuando finaliza la etapa de educación primaria, tal y como se recoge en el RD 157/2022 de 1 de marzo, por el que se establecen la ordenación y las enseñanzas mínimas de la Educación Primaria.

            Tras el marco teórico que justifica la propuesta se presenta la base curricular de la misma, y como experiencia didáctica se proponen una serie de estrategias educativas para implementarla, así como un ejemplo concreto de programación de aula a partir de una situación de aprendizaje transversal para un nivel de 6º de primaria.
