Published: June 2024

The structure of vascular bundles and the mechanical properties of fibers are crucial factors determining the utilization of bamboo. This study investigated the structure of vascular bundles and evaluated the morphological and micromechanical properties of the fibers in Oligostachyum sulcatum. The results showed that the fiber length and width of O. sulcatum meet the requirements of raw materials for the papermaking process. However, the fiber content in O. sulcatum is relatively low, which may increase the cost of papermaking. The vascular bundle growth exhibited non-uniformity, especially at the top part, with no discernible pattern in bundle area changes. The nanoindentation testing demonstrated that the bamboo’s indentation modulus of elasticity (IMOE) and hardness values were comparable to those of moso bamboo (Phyllostachys edulis), suggesting its potential as a substitute in engineering applications.

Published: June 2024

Static life cycle assessment (LCA) methodologies fail to consider the temporal profiles of system inputs and outputs (including emission timing), such that they underestimate the benefits of temporarily stored biogenic carbon in bioproducts, such as cotton. This research focuses on greenhouse gas emission timing and applies dynamic emission accounting to the life cycle of cotton woven pants. The significance of temporary biogenic carbon storage and emission timing is illustrated by converting the 2017 Cotton Incorporated static LCA to a dynamic model using the Dynamic Carbon Footprinter (baseline scenario). A reduction in cumulative radiative forcing for dynamic relative to static modeling of 22%, 5%, and 2% are observed at 10-years, 30-years, and 100-years, respectively. Alternative scenarios analyzed include converting cotton woven pants at end of life to bioenergy, to compost, or to building insulation, an alternative cotton production scenario using regenerative agricultural practices, and two pants extended lifetime scenarios. The regenerative agricultural practice scenario provides reductions in cumulative impacts compared to the baseline scenario of 96%, 69%, and 105% after 10, 30, and 100-years, respectively. A 3x extension in the lifetime of pants provides a benefit in reduced cumulative impacts of 31%, 40%, and 41%, after 10, 30, and 100-years, respectively. This case study with cotton demonstrates that dynamic LCA is a useful tool for assessing the benefits of biobased products, and it allows for more nuanced analysis of reductions in climate impacts in both the short- and long-term time horizons.
Review of performance, marketing and milk processing of dairy cattle production system in Ethiopia
Authors: Kassa Awoke
Published: June 2024

Ethiopia has a huge potential to be one of the key countries in dairy production for various reasons. It includes a large population of milk cows, a huge potential for production of high quality feeds under rain fed and irrigated conditions, existence of a relatively large human population with a long tradition of consumption of milk and milk products and hence a potentially large domestic market. Despite its potential for dairy development, productivity of indigenous livestock genetic resources in general is low, and the direct contribution it makes to the national economy is limited. The main source of milk production in Ethiopia is cattle but small quantities of milk are also obtained from goat and camel in pastoralist areas of the country. Based on the system of production, Milk production can be viewed at three different sources. These include: Pastoral milk Production, The highland smallholder milk production and Urban and peri-urban milk production. Milk and milk products are channeled to consumers through both formal and informal marketing systems. Ethiopia has a low level of milk consumption compared to other countries in the region (Kenya=90lt/cap; Uganda=50lt/cap). Challenges and problems for dairying vary from one production system to another and/or from one location to another. Underdevelopment and lack of market-oriented production, lack of adequate information on livestock resources, inadequate permanent trade routes and other facilities like feeds, water, holding grounds, lack or non-provision of transport, ineffectiveness and inadequate infrastructural and institutional set-ups, prevalence of diseases, illegal trade and inadequate market information (internal and external) are generally mentioned as some of the major reasons for the poor performance of this sector.

The study also shows that A. galli is common health problem in poultry chicken so suggest the need of proper poultry management.
Pediatric brainstem glioma: a rare childhood cancer - clinical profile, treatment, and challenges of management - a single-center experience from a developing country
Authors: Kumar Ghosh Dr. Ashis , Zahangir Kabir Dr. SM Rashed , Kumar Saha Dr. Sanat
Published: June 2024

Introduction: Brainstem gliomas (BSGs) occur in the brainstem, located at the base of the brain. BSGs account for 10-20% of all primary CNS tumors. In a hospital-based study conducted at NICRH, BSGs constituted 7.69% of all childhood brain tumors. Objective: To determine the clinical profiles of childhood BSGs and assess the outcomes of pediatric BSGs while addressing the challenges of management. Methodology: It was a cross-sectional prospective study with a sample size of 44. We included all children during the study period and analyzed their data.The children were under 18 years of age. The study period was January 2020 and October 2022 at the Department of Pediatric Hematology and Oncology at the National Institute of Cancer Research and Hospital (NICRH), Bangladesh. Results: There were 44 patients, comprising 29 males and 15 females. The mean age of onset was 7 years. The majority (43.2%) of children fell within the 5-9 years age group. The most common symptoms were limb weakness, ataxia, and vision defects. The duration of symptoms varied from 10 days to 2 years. Sixteen of the patients experienced intracranial hypertension, which led to the development of hydrocephalus. The lesions were pontine in 18 cases, involving the entire brainstem in 13 cases, both pons and medulla in 7 cases, and medulla in 3 cases. Six patients underwent surgical intervention with histological evaluation, revealing astrocytoma (9.1%), oligodendroglioma (2.3%), and ependymoma (2.3%). Twenty-four (54.5%) patients received treatment, while others were unable to do so. The follow-up period extended to 12 months from the last enrollment. Only 8 patients completed both chemotherapy and radiotherapy treatments; other children discontinued or abandoned treatment due to financial constraints or the unavailability of 3D radiotherapy. Out of 44 children, a total of 41 patients passed away, with a mean survival period of 3.9 months. This is due to the high treatment cost in the private sector and disorganized government medical services for children with cancer. Conclusion: Most of the tumors in this series were located in the pons and demonstrated aggressive characteristics. The majority of our patients did not have access to radiotherapy due to their poor economic condition and the inadequate management of our government health system.

Generic and simplified approaches for the structural analysis of precast concrete sandwich panels
Authors: Hamed Ehab
Published: June 2024

This paper presents a comparison between three numerical models developed for the structural analysis of composite precast concrete sandwich panels under lateral loading. The first model is based on a full finite element analysis where “slip” between the layers is obtained from the elastic deformability of the various components. The second model is based on a simplified finite element analysis where the effect of the shear connectors is smeared and modeled through an effective shear stiffness of the insulation layer. The third approach provides closed-form expressions for evaluating the deflection and is based on the classical sandwich beam theory where the shear connectors are considered through the effective stiffness of the insulation, similar to the second model. The structural response obtained from the three models was compared for various panel configurations and good correlation was obtained. A reasonable agreement with test results from the literature was also demonstrated. Therefore, both the simplified finite element model and the classical sandwich beam theory (closed-form solution) are recommended for the elastic structural analysis and for estimating the degree of composite action at the serviceability limit state of precast concrete sandwich panels.

Knock out aryl hydrocarbon receptor gene in adipose-derived mesenchymal stem cell line (PT-5006) by CRISPR/Cas9
Authors: Duc Le Hoang , Tien Vu Thi , Nam Nguyen Trung
Published: June 2024

Mesenchymal stem cells (MSCs) have garnered significant attention in biomedical studies due to their remarkable properties, such as self-renewal, differentiation into diverse cell types and immune responses. The proliferation and differentiation of MSCs are significantly influenced by the ligand-dependent transcription factor known as the aryl hydrocarbon receptor (AhR). In order to understand the roles of Ahr in adipose-derived MSCs (AD-MSCs), we disrupted the Ahr gene in this work using CRISPR/Cas9 gene editing technology. The gRNA/Cas9 dual vector and donor vector were introduced into the AD-MSC cell line (PT-5006). Green fluorescent protein (GFP) expression and puromycin resistance were used to identify the transfected cells. AhR-KO cells were cloned and confirmed by PCR and sequencing. By using RT-qPCR, the expression levels of AhR and the Ahr-related gene Cyp1B1 were investigated. The results showed that the knocked out of AhR using CRISPR/Cas9, resulting significantly decreased expression of 7.69-fold for AhR and 3.70-fold for Cyp1B1 in the cells. These cell clones and CRISPR/Cas9 vectors could be used as tools to investigate the functions of AhR in both AD-MSCs and other cell types.

Aim. To assess the prevalence of traditional risk factors and analyze the predictors of recurrent cardiovascular events in patients with acute coronary syndrome (ACS).

Material and methods. A total of 482 patients with ACS were included. The follow-up lasted three years. The composite endpoint (CE) included recurrent unstable angina, nonfatal myocardial infarction, repeated percutaneous coronary intervention (PCI), nonfatal ischemic stroke, hospitalization for decompensated heart failure, and cardiovascular death.

Results. A high prevalence of traditional risk factors was revealed (dyslipidemia — 467 (96,9%), hypertension — 464 (96,3%), consumption of junk food — 450 (93,4%), sedentary lifestyle — 416 (86,3%)). During the three-year follow-up period, 90 patients had CE. Compared with patients without CE (n=392), patients with CE were significantly more likely to have a long-term CAD (69 (76,7%) vs 241 (61,5%), p=0,007), ACS accompanied by shortness of breath (50 (55,6%) vs 160 (40,9%), p=0,013); they had previously undergone myocardial revascularization (38 (42,2%) vs 116 (29,6%), p=0,024), often by PCI (36 (40,0%) vs 100 (25,5%), p=0,009), especially in the left main coronary artery (LMCA) (6 (6,7%) vs 3 (0,8%), p=0,002); they were more likely to develop in-hospital acute left ventricular failure (11 (12,2%) vs 18 (4,6%), p=0,012), had a lower hemoglobin level and hematocrit (p<0,05 for all); they more often required intensification of lipid-lowering therapy (86 (100%) vs 334 (85,2%), p=0,002), compliance with which was lower (6 (6,7%) vs 105 (26,8%), p<0,001) than in patients without CE. Previous intervention on the left coronary artery, non-compliance with lipidlowering therapy, hematocrit level 3 months and hemoglobin level 1 year after ACS were predictors of recurrent events. The combination of surgery on left coronary artery and non-compliance with lipid-lowering therapy demonstrated significantly less freedom from CE compared with other patients (77,4% vs 94,6%, p<0,001).

Conclusion. A high prevalence of traditional risk factors in the population of patients with ACS was revealed, and potential predictors of recurrent cardiovascular events were identified.

Aim. To analyze the readiness of the professional medical community for changes in the classification and implementation of novel approaches to heart failure (HF) treatment based on an online survey.

Material and methods. Anonymous online survey of physicians on the official website of the Russian Society of Cardiology (www.scardio.ru) "Chronic heart failure. Unsolved issues" was held from September 30 to October 4, 2023. The survey involved 1015 doctors with an average length of work >10 years, mainly cardiologists (n=810, 83,2%).

Results. The majority (n=591, 58,2%) of respondents considered it necessary to identify the HF prestage in the classification, similar to prediabetes or prehypertension, while only 2,2% (n=22) of respondents did not consider it necessary to indicate the HF risk in the classification. Simplifying the HF classification based on the left ventricular ejection fraction (LVEF) values with the identification of only two gradations of LVEF <50% and LVEF ³50% was supported by 60,3% (n=612) of specialists.

The majority (80,8%) of respondents supported increasing the time of admission of a patient with HF to 30 minutes to ensure the healthcare quality. According to the survey, only 32% of respondents have the ability to determine the brain natriuretic peptide level in patients with HF without restrictions, which indicates insufficient material security for the implementation of clinical guidelines in practice. Quadruple therapy is prescribed to every patient with HF by only 37% of respondents who took part in the survey, which may indicate clinical inertia regarding following the guidelines.

Conclusion. In general, the survey demonstrated high awareness of physicians about the problem of HF and readiness to assess the risk and diagnose HF at preclinical stages, as well as a positive attitude towards changing the classification.

Abstract The aim of this clinical, prospective, randomized, and parallel study was to evaluate different in-office treatments for dentin hypersensitivity (DH). One hundred ninety-two teeth with non-cavitated root exposures were treated using different desensitizers: fluoride varnish (Duraphat - FLU); bioactive ceramic solution (Biosilicate - BIOS); universal self-etching adhesive (Single Bond Universal - SBU); bioactive photoactivated varnish (PRG filler - SPRG). The degree of DH was analyzed using a visual analog scale (VAS) and computerized visual scale (CoVAS), before treatments and after 7, 15, and 30 days from the first session. Comparisons among desensitizers were performed using the Kruskal-Wallis and Dunn's tests. Friedman test was used to compare between times (p ≤ 0.05). Comparing desensitizers FLU presented a higher value of DH than BIOS using VAS at 7 days, however, no differences were found using CoVAS analysis. Comparing times, BIOS and SBU showed a reduction in DH after 7 days and SBU showed a reduction at 30 days compared to 7 days using VAS. FLU and SPRG groups reduced DH from 15 days to 30 days using VAS. There was a reduction in DH for FLU, BIOS, and SBU after 7 days and for BIOS this reduction also occurred at 30 days when compared to 15 days using CoVAS. SPRG group showed a reduction from 15 to 30 days. All desensitizers tested were able to reduce the initial sensitivity. The bioactive ceramic solution reduced the DH gradually after 30 days using computerized analysis.

ABSTRACT Introduction: Desmoid Tumors (DT) are rare neoplasms with higher incidence in younger women. Methods: Retrospective, single-center analysis of patients with DT. Variables were age, sex, biopsy, treatment and recurrence. The disease-free survival (DFS) was calculated with the Kaplan-Meier method. Results: 242 patients were evaluated, mean age was 34 years, 70.7% women, 44.4% originated in the trunk/abdomen and 54.5% had size > 5cm. Surgery was performed in 70.2%, 31% with negative margin and only 57% with previous biopsy. Recurrence rate was 38% and 1,2,5-year DFS was 75.3%, 64.2%, 57.8%, respectively. Size (p = 0.018) and tumor location in the dorsum (p = 0.001), extremities (p = 0.003) and pelvis (p = 0.003) were related to higher relapse rate. Conclusion: our data reinforces the need to gather data from real world practice and the importance of awareness of DT and medical education about DT behavior and best approach due to the high rates of surgery and elevated number of patients treated without biopsy.

Published: June 2024

ABSTRACT Objective: To evaluate patients with arthrogryposis submitted to extensive surgical treatment with a minimum of 10 years of follow-up regarding the clinical and radiological aspects and the quality of life, using the 36-Item Short Form (SF-36) and the Disease-Specific Instrument (DSI). Methods: A retrospective study selected 33 patients, totaling 64 operated feet. Results: The mean age of the patients was 17.9 years (12-39 years), and the mean follow-up time was 14.8 years (11-17). Amyoplasia represented 78.7% of syndromic diagnoses. Isolated posteromedial lateral release (PMLR) was performed in 21.8% of the feet, 27.2% of which required additional bone surgery, and about 50 feet (78.1%) were submitted to PMLR, lateral column shortening, and/or talectomy. In total, 46 talectomies were performed (71.8% of the feet), out of which 44 were the first procedure of choice. SF-36 questionnaire was evaluated and showed that 93.9% of the patients did not have restrictive and disabling pain, and the same percentage considered themselves as healthy and had good expectations for the future. Conclusion: Arthrogrypotic feet are difficult to treat, require many recurrent surgical procedures, and relapses are the rule. Stiffness is a common feature of these feet, and residual deformities were frequent. Level of Evidence IV; Case Series, Therapeutic Studies.
Efficacy of microbiological and chemical insecticides as alternatives for control of Myochrous armatus (Baly, 1865) (Coleoptera: Chrysomelidae)

Published: June 2024

Abstract Myochrous armatus (Baly, 1865) (Coleoptera: Chrysomelidae) causes considerable losses to soybean crops in Brazil and several other South American countries. Applying biological insecticides can be an effective alternative to suppressing this pest. The objective of this study was to assess the efficacy of microbiological insecticides formulated from the fungi Beauveria bassiana + Metarhizium anisopliae (Bometil) and B. bassiana alone (Ballvéria), and the bacterium Bacillus thuringiensis (Acera) alone and in combination with the chemical insecticides fipronil, ethiprole and chlorpyrifos, against M. armatus adults. The insecticides based on B. bassiana + M. anisopliae were found to be more pathogenic than those based on B. bassiana, causing cumulative mortality rates in the ten days of 85.0 and 65.0% respectively. In contrast, B. thuringiensis caused 92.5% mortality. These products alone and in combination were effective for control at their lowest concentrations. Therefore, the use of microbiological insecticides individually or in combination with chemical insecticides is a promising alternative for the integrated management of M. armatus.

ABSTRACT This study evaluated whether there were differences in vaccination coverage rates between municipalities with different vaccination strategies regarding the species and the coverage rates during different day periods. The vaccination period was categorized as M1 (morning; 09h00 am - 11h00 am), M2 (morning/afternoon; 11h00 am - 01h00 pm), M3 (afternoon; 01h00 pm - 03h00 pm), and M4 (afternoon; 03h00 pm - 05h00 pm). A repeated measures model compared the vaccination rate between periods and municipalities. The interaction between time and municipality was statistically significant (P < 0.01), indicating that the vaccination rate difference between periods depended on the municipality analyzed. Results of the difference between proportions analysis revealed that municipality B vaccinated 3.3% (2.2%-4.4%, 95% confidence limits) less dogs and 20.1% (17.9%-22.4%, 95% confidence limits) less cats than the municipality A. In municipality A, the vaccination rate in period M1 was higher than in periods M3 (P = 0.07) and M4 (P < 0.01). The vaccination rate was higher in M2 than in M4 (P < 0.01). In municipality B, the vaccination rate in period M1 was higher than in M2 (P = 0.01). The vaccination rate in M2 was lower than that observed in M3 (P = 0.01) and M4 (P = 0.01). Based on these results, mass vaccination campaigns have better results during the week, with the highest vaccination rate at lunchtime.

ABSTRACT This study aims to describe the effects of stabling on thermographic characteristics of adult equine limbs, to compare the level of animal welfare between horses kept loose and those under continuous stabling and to investigate whether the Infrared Thermography (IRT) can be an effective tool to evaluate the welfare of equines. 24 gelding horses of Brazilian Sport Horse breed, aged between 5 and 9 years and weighing 500 ± 50kg were used in a 6-week trial. They were divided into 2 groups: 1) Paddock - equines kept in paddocks and ridden exclusively on urban patrol; 2) Stall - animals that ridden exclusively on urban patrol, but were kept in continuous stabling, housed in 12m² with concrete and bedless stables. Every animal was evaluated once a week over six weeks. Animal behavior and temperature of the eyes and distal extremities of the limbs as well as blood samples were collected. The confined horses showed stereotyped behavior and higher serum cortisol, indicating lower animal welfare when compared to those managed in a pasture. Limb IRT showed predictive potential for identifying chronic stress as the discriminating analysis showed 74.5% hits while eye temperature was not efficient for this purpose.

ABSTRACT Intramedullary nails are the focus of scientific studies in small animal orthopedic surgery because the use of these materials in fractures of immature, small-sized patients, and in proximal bone regions is challenging. In this context, elastic osteosynthesis has been strongly advocated for the treatment of patients under four months of age. Therefore, the objective of this study was to report two cases of non-exposed complete fractures of proximal femurs in felines, resulting from trauma, both patientes under six months of age, treated with the elastic technique using a locked intramedullary nail. Both cases were treated through a surgical approach to the fracture site using the "open, but don't touch" method. In both cases, the bone consolidation process occurred in less than 60 days, along with satisfactory and early patient ambulation. Given the advocated osteosynthesis technique in the two patients and the promising results obtained, it is admitted that the use of locked intramedullary nails is a viable alternative for the treatment of proximal bone fractures in young felines.

ABSTRACT The purpose of the present study was to evaluate the effects of spineless cactus species in diets of feedlot lambs on intake, apparent absorption and retention of macrominerals. Thirty-six uncastrated male Santa Inês lambs presenting an average body weight of 22.0±2.87 kg were distributed in a completely randomized design with three treatments [diet containing Tifton-85 hay as exclusive roughage (control), Miúda cactus cladodes-based diet or Orelha de Elefante Mexicana (OEM) cactus cladodes-based diet] and twelve replicates. The calcium (Ca) and magnesium (Mg) intakes (from feed and total) were higher (P=0.001) for animals fed diets supplemented with Miúda spineless cactus. The spineless cactus, regardless of species, caused a mean decrease of 45.4% in sodium intake (P=0.001). There was a net loss of Ca by lambs fed OEM spineless cactus (P=0.001). The absorption and retention of P was higher in control diet compared to the OEM diet (P<0.05). The amount apparently absorbed, and body retention of Mg were higher for lambs fed Miúda spineless cactus-diet (P=0.001). Therefore, the diet containing Miúda spineless cactus increases the intake and body retention of Ca and Mg in lambs. However, the use of OEM spineless cactus may be unsuitable for a long-term.

ABSTRACT Hysterothylacium species are perhaps the most abundant and diverse group of marine ascaridoids. Identification of larval stages at specific levels is very problematic. This study describes the occurrence of Hysterothylacium larvae parasitizing the peritoneal cavity and mesenteries of Saurida tumbil purchased from fish markets in Saudi Arabia. Fish were visually inspected for nematodes using micro- and macroscopic examinations. Nematodes were assigned to genus level based on morphology and identified at specific level by sequence analyses of 18S rRNA and COI genes. Morphological examination by light microscopy showed that worms identified as third-stage larvae (L3) belonged to genus Hysterothylacium Ward and Magath, 1917. COI sequences from host confirmed identity of host as S. tumbil as it resulted in identical sequences from S. tumbil in GenBank. Identity of L3 based on 18S rDNA sequences confirmed their identity as H. thalassini and showed high similarity to sequences in GenBank. A unique hitherto sequences of L3 related to COI region have been reported herein. This is the first record of Hysterothylacium L3-stage parasitizing lizardfish in Saudi Arabia. Therefore, this study represents the importance of a combination of morphological and molecular tools for taxonomy and systematics of ascaridoids at specific level and confirming its host identity.

Published: June 2024

ABSTRACT Objective The aim of this study was examined the effects of sociodemographic characteristics and health status of adults on nutritional literacy. Methods This cross-sectional study was conducted among adults (aged >20 years) in Ankara, Turkey between April to June 2022. The first part of the survey consisted ofquestions aimed at determining the socidemographic characteristics and health status of the individuals. In the second part, the Nutrition Literacy Instrument adopted in Turkish was utilized to assess the nutrition literacy status of the participants. Based on this scale, a score above 38 was classified as “adequate”, a score between 29 and 38 as “borderline” and a score below 29 as “inadequate”. Results In this study 676 individuals was participated, among whom 50.6% (n=342) were women and 49.4% (n=334) were men. The average total nutritional literacy score of the individuals was 33.06±3.49. It was found 9.3% of Individuals had inadequate nutrition literacy, 87.4% had borderline nutrition literacy, and 3.3% had adequate nutrition literacy. Nutrition literacy levels were found to be statistically significant between genders, with women exhibiting greater levels of nutrition literacy than men (p<0.05). Furthermore, a significant relationship was found between education levels and nutritional literacy (p<0.05). Specifically, individuals who graduated from high school and university demonstrated higher levels of nutritional literacy compared to those who graduated from primary and secondary school. Conclusion It has been determined that gender and education among socio-demographic characteristics have a significant effect on nutritional literacy.

Authors: Costa Octavio Pennella Fenelon , Dalcim Maria Luiza , Smaira Sumaia Inaty , Lovadini Gustavo Bigaton
Published: June 2024

ABSTRACT Musical hallucinations and musical obsessions are distinct phenomena. The first can be understood as a manifestation of the musical ear syndrome, which produces deafferentation auditory hallucinations, while the latter is an obsessive symptom of obsessive-compulsive disorders. Both symptoms are often poorly understood and mistaken for one another or for signs of psychotic disorders. We report two cases, one characterized by musical hallucinations and the other by musical obsessions, both with comorbid hearing impairment, which is the main confounding factor in their differential diagnosis. We critically compare the two cases and their key features, allowing diagnostic differentiation and a targeted therapeutic approach.

Published: June 2024

ABSTRACT The world's population is experiencing an aging process, which is resulting in an increase in diseases such as Alzheimer's disease. Consequently, more and more people need care, which can lead to overload and harm to their family's quality of life. Objective: Identify the psychosocial factors affected by the burden on family caregivers of people with Alzheimer's disease. Methods: Forty-nine family caregivers of people with Alzheimer's disease, from a city in Minas Gerais, Brazil, participated in the study. They filled out a form of sociodemographic variables, and answered the Burden Interview Scale (BI-Zarit), Quality of Life in Alzheimer's Disease Caregiver version (CQoL-AD), the Depression, Anxiety and Stress Scale (DASS-21), the Mindfulness and Awareness Scale (MAAS) and the Clinical Dementia Rating Scale (CDR). Results: All participants were female with an average age of 54.26 (±8.99). Daughters comprised 77.55% of the sample, and 34.69% were sole caregivers. The Bi-Zarit scale positively and significantly correlated with DASS-21 Depression (r=0.440; p=0.002), DASS-21 Anxiety (r=0.415; p=0.003), DAAS-21 Stress (r=0.583; p<0.001). On the other hand, it showed a negative correlation with MAAS (r=-0.429; p=0.002) and CQoL-AD (r=-0.533; p<0.001). Conclusion: This study demonstrates that family caregivers of people with Alzheimer's disease may be overloaded, and that the heavier the burden, the lower level of attention, the worse quality of life and the greater the possibility for the caretaker to present symptoms of depression, anxiety, and stress.
Memória. Entre Tailândia, Colômbia, Escócia. Ponto de escuta e sons ambientes
Authors: Costa Fernando Morais da
Published: June 2024

Resumo Este artigo, como apresentamos em sua versão de apresentação oral, tem por objetivo analisar a interação entre o conceito de ponto de escuta, os ruídos e os sons ambientes. Para tanto, teremos como centro o longa-metragem Memória (Apichatpong Weerasethakul, 2021). Nos interessa demonstrar a relação possível entre a personagem principal e nós, como espectadores, pela partilha de um incerto ponto de escuta que transita entre sonoridades subjetivas e objetivas. Temos como hipótese que tal incerteza sobre o ponto de escuta, por parte da personagem e estendida aos espectadores, relativiza dicotomias da teoria do cinema sobre a localização espacial ou subjetiva dos sons. Nossa análise tem a intenção de abrir possiblidades de diferentes resultados quanto à recepção e identificação sonoras.

ABSTRACT Objective: To identify the learning needs and the orientations received by patients in the preoperative period of coronary artery bypass surgery (CABG). Method: Descriptive study, with a qualitative approach. Data collection took place from January to April 2021, through interviews carried out with 13 pre-operative patients admitted to the cardiovascular unit of a university hospital in Northeastern Brazil. The data was analyzed using descriptive statistics and the content of the interviews was processed in the software Interface de R pour les Analyses Multidimensionnelles de Textes et de Questionnaires. Next, an analysis of textual and similarity classes was carried out. Results: The learning needs that were analyzed were divided in five classes: events that precede the surgery in the hospital; instructions received about the surgery; sites and recovery time after surgery; general questions about the surgery and content for the educational resource. Patients reported needs related to the process of disease, surgical procedures, and care before and after surgery. With regard to orientation, 53.85% reported not having received any. Final considerations: The study identified that patients seldom received orientation. They need education on topics related to the process of the illness, the heart, surgical procedures, exams, care environments, risks, benefits, results, and changes in lifestyle to maintain health and quality of life.

Published: June 2024

ABSTRACT Type I Chiari malformation (MCI) is a generally congenital condition of herniation of the cerebellar tonsils below the foramen magnum, which can lead to compression of structures close to the posterior cranial fossa or obstruction of the flow of ventral cerebrospinal fluid. Type I, although rare, is the most commonly found in the population. This study aimed to report the findings of video endoscopy of swallowing, speech assessment, level of oral intake, nutritional risk and therapeutic planning in three cases of Type I Chiari malformation. Data were collected regarding the assessment of mobility and strength of tongue, Maximum Phonation Time (MPT), cough efficiency and the Eichner Index. The level of oral intake and pharyngeal signs of dysphagia were analyzed in four food consistencies, according to the International Dysphagia Diet Standardization Initiative (IDDSI) classification, using swallowing video endoscopy. For analysis and classification of pharyngeal residues, the Yale Pharyngeal Residue Severity Rating Scale (YPRSRS) was used, while the Malnutrition Screening Tool (MST) was used to track nutritional risk. Reduced tongue mobility and strength and reduced MPT were observed, while pharyngeal signs varied between cases, with the presence of incomplete glottic closure, posterior oral escape, multiple swallows, pharyngeal residues and laryngeal penetration.

ABSTRACT This study aims to analyze exposure to pesticides and harm to the health of workers on sugarcane plantations in Pernambuco. This participatory research was conducted in rural territories of five municipalities with a strong presence in sugarcane-planted areas. The primary data were produced in workshops with rural workers to construct a participatory rural diagnosis, analyzed through condensation of meanings, and interpreted in light of the theoretical framework of Latin American critical epidemiology. The results are presented in three sections: i) Flowchart of work on sugarcane plantations; ii) Exposure to pesticides used on crops; iii) Harm to worker’s health. We conclude that permanent exposure to pesticides involves working on sugarcane plantations and emerges from a historical and socio-environmental construct in which the ways of life of the territories under the control of sugarcane agribusiness are subsumed. Public policies are recommended to promote family farming with diversification, flow, distribution of agroecological production, and strengthening primary health care and integrated epidemiological, health, environmental, and worker surveillance actions.

RESUMO Objetivou-se analisar a Frente pela Vida (FpV), um ator da sociedade civil organizado no campo da saúde, que buscou incidir politicamente diante da crise sanitária da pandemia da covid-19 no contexto do governo Bolsonaro. As informações foram obtidas por meio de revisão documental de publicações da FpV, bem como pela observação participante de reuniões, manifestações, lives e eventos nos quais participou ou organizou, além de entrevistas com participantes do seu grupo operativo. A análise considerou as categorias origem, trajetória, atores, gestão, relação entre a FpV e movimento sanitário, sustentabilidade, desafios e perspectivas da FpV. Os resultados evidenciam que a FpV capitaneou uma grande rede de políticas formada por sujeitos individuais e coletivos, entidades científicas e organizações representativas de diversos segmentos da sociedade civil, conformando uma atualização do movimento sanitário com ampliação de sua base de sustentação social. Sua trajetória contemplou, principalmente, a ação técnico-científica e política em múltiplas arenas, tendo nos Poderes Executivo, Legislativo e Judiciário, e na sociedade civil, espaços privilegiados de inserção. Conclui-se que a FpV se revelou importante ator social na conjuntura recente, tensionando o Estado na defesa da vida, do direito universal à saúde e da expansão e fortalecimento do Sistema Único de Saúde.
