Metal plating frequently employs nickel (Ni) and copper (Cu) as anodes. Cu/ Cu-Ni film formed has many advantages, such as better corrosion resistance and high hardness characteristics. This study aims to assess the properties of Cu/Cu-Ni film, such as phase, surface morphology, crystallographic orientation, hardness, corrosion analysis, and contact angle, which were fabricated using electrodeposition with various Ni salt additions (0.3, 0.5 and 0.7 M). In addition, the cathode current efficiency (CCE) and deposition rate of the Cu/Cu-Ni electrodeposition were also investigated. An increase in Ni salt in the plating bath could enhance the pH, promoting higher CCE and depleting hydrogen evolution at the cathode, leading to the presenting Ni phase in the alloy. The higher concentration of Ni salt in the solution could also enhance the deposition rate due to a shift to a pH value, which affects the roughening of the surface morphology, promoting a higher contact angle. All crystal structures generated by Cu/Cu-Ni electrodeposition were FCC, with the preferred orientation of the (111) plane. Crystallite size and lattice strain depend on the deposition rate. Less crystallite size and lattice strain affect the film’s hardness and corrosion resistance. Moreover, the third bath had the resulting Cu-Ni layer with the best hardness and corrosion rate of around 136 HV and 0.081 mmpy.

Published: July 2024

Pillarization of bentonites (from East Java) with ZnO semiconductors has been synthesized using co-precipitation methods into a ZnO/Bentonite composite and applied as a catalyst in a photocatalytic process to remove Methyl Orange (MO) dyes. The optimum pH condition of MO dyes is at pH 2 with a degradation rate of 22.91% (from 15 mg/L to 11.523 mg/L). The optimum ZnO/Bentonite catalyst weight condition is 200 mg, with a degradation rate of 29.11% (from 15 mg/L to 10.596 mg/L). The optimum time condition for UV lamp irradiation is 60 minutes, with a degradation rate of 64.92% (from 15 mg/L to 5.244 mg/L). The kinetics of MO photocatalytic reaction using ZnO/Bentonite catalyst follows the pseudo-first-order Langmuir Hinshelwood-Santosa kinetic model with photocatalytic reaction rate constant (k1) of 0.014 and photocatalytic equilibrium constant (K) of 0.012.

Published: July 2024

Increasing bacterial resistance to antibiotics has become a serious threat to global public health. In this context, this study aims to evaluate the antimicrobial activity of titanium dioxide nanoparticles (TiO2 NPS) synthesized using the sol-gel method. TiO2 NPS samples were prepared and characterized for morphology via field-emission scanning electron microscopy (FESEM) and X-ray diffraction (XRD) analysis. Kirby-Bauer disc diffusion method was used to test the antimicrobial activity of TiO2 NPS against Gram positive bacteria Staphylococcus aureus, Gram negative bacteria Escherichia coli, and pathogenic fungus Aspergillus penicillioides. The results showed that TiO2 NPS effectively inhibited the growth of microorganisms, with significant inhibition zones especially against fungi. The antimicrobial mechanism of TiO2 NPS involves the formation of hydroxyl radicals and superoxide ions that damage the cell membrane of microorganisms. The implications of this study are the development of potential antimicrobial nanomaterials for biomedical and environmental applications, as well as the importance of considering the physical and chemical properties of TiO2 NPS in designing effective infection treatment strategies.

Published: July 2024

In this study, we conducted the extraction of silver nitrate (AgNO3) using the chemical reduction evaporation method, involving silver metal (Ag) with a molarity of 7.716 M and nitric acid (HNO3). The heating process via evaporation was carried out at 85oC for 2 hours. Subsequently, the synthesis of silver nanowires (AgNWs) was performed using a 0.3 M of AgNO3 solution in ethylene glycol (EG), polyvinyl pyrrolidone (PVP), and Iron (III) Chloride hexahydrate (FeCl36H2O). XRD analysis of the AgNO3 sample revealed an orthorhombic crystal structure with a single AgNO3 phase peak. In AgNWs, three crystalline phases were observed, with the Ag phase being the most dominant. The average crystal size of AgNO3 and AgNWs was 109.42 nm and 22.06 nm, respectively. The average crystal size of the AgNO3 sample may be influenced by the aggregation between crystal nuclei during the heating process. XRF analysis indicated a 98.84% Ag concentration in AgNO3. SEM-EDS analysis showed that the AgNO3 sample had a non-aggregated morphological structure, with particle size measuring 49.46 μm and an overall AgNO3 purity of 92.68%. The SEM image of the AgNWs sample displayed a very homogeneous diameter of ∼200 nm with a length of around 10-20 μm. Meanwhile, AgNWs exhibited a morphology resembling rod-shaped wires with a purity of 68% for Ag.

Published: July 2024

This article outlines the development of a Fiber Bragg Grating (FBG) intended for use as a sensor for CH4 and CO2 gases. Following fabrication, the FBG was effectively treated with a layer of Graphene Material through a modified RF Sputtering process. This coating procedure involved introducing argon gas into the chamber and subjecting the FBG, securely held by two vacuum stages, to a temperature range of 27°C to 600°C by adjusting the power supplied to the cathode and anode, ranging from 0 to 125 Watts. Subsequently, the FBG was employed as a key sensing element within an experimental setup aimed at measuring gas concentrations within a confined space. The assessment involved analyzing the reflected signal of the FBG using an Optical Interrogator System, which demonstrated a shift in the Bragg wavelength of the reflected signal corresponding to varying gas concentrations. This study indicates promising outcomes for the Graphene-coated FBG as a gas sensor. The sensor’s sensitivity was evaluated based on the Bragg wavelength shift resulting from gas presence within the chamber. The Graphene-coated FBG exhibited sensitivities of 3.3 ppm for CH4 and 3.7 ppm for CO2, surpassing those reported in prior research efforts.

Published: July 2024

This study aims to evaluate the biocompatibility of a novel filler material intended to improve the longevity of polymer systems used in prosthetics in respect of cytotoxicity and skin irritation. RTV50F silicone elastomer incorporated with various percentages of hexagonal boron nitride (H-BN) (0.1, 0.3, 0.5, 0.7, and 1 wt%) have been tested. Silicone without H-BN was utilized as the control for comparison. The in vitro cytotoxicity test includes specimens (n=18) with 10 mm in diameter and 2 mm in thickness applied directly to the normal human fibroblast cell line (NHF) and incubated for 72 hours, then 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay was used to determine the cell viability. The skin irritation test was conducted in vivo, in which specimens (n=12) with 25 mm × 25 mm dimensions were applied on the back of 5 different rabbits for 4 hours, then the skin response was evaluated after 24, 48, and 72 hours. The acquired in vitro data were statically analyzed using one-way ANOVA and post-hoc Tukey’s tests with GraphPad Prism 8, where P-value < 0.05 was considered statistically significant. The H-BN powder and silicone specimens were studied via field emission scanning electron microscopy (FE-SEM). The results revealed a negligible effect of maxillofacial silicone on cell viability after 72 hours of incubation, only one group (1wt%) showed a significant difference compared to the control group but the toxicity percentage didn’t exceed 30% of cell viability and there was no skin irritation during the in vivo test.

Published: July 2024

Ketoprofen is a non-steroidal anti-inflammatory drug (NSAID) whose formulation options are limited due to its low dissolution rate in aqueous media. This research aimed to enhance the solubility of ketoprofen in distilled water and to compare the anti-inflammatory and analgesic effects of its resulting multicomponent crystal with tromethamine. The binary phase diagram of ketoprofen-tromethamine was created across molar ratios ranging from 1:9 to 9:1. The multicomponent crystal comprising ketoprofen and tromethamine in the selected ratio was synthesized using a solvent drop grinding method and subjected to further characterization for thermal properties, crystallinity, chemical groups, and morphology. The dissolution rate assessments were evaluated in CO2-free distilled water. Pharmacological analyses examined the anti-inflammatory and analgesic effects of the multicomponent crystal. The binary phase analysis identified the 5:5 (1:1) molar ratio as optimal in forming a multicomponent crystal. Thermograms and diffractograms revealed crystalline alterations attributed to a new crystalline phase. The new multicomponent crystal exhibited approximately 2.7 times higher dissolution rate after 30 minutes, outperforming pure ketoprofen. Pharmacological assessments demonstrated superior analgesic effects of the multicomponent crystal. In summary, the ketoprofen-tromethamine cocrystal in 1:1 molar ratio offers enhanced dissolution rate and provides better analgesic activity than ketoprofen alone.

Plectranthus scutellaroides is a plant with attractive colored leaves. It contains secondary metabolite compounds such as flavonoids and phenolics, which provide skin protection against ultraviolet rays from the sun. The research aims to investigate the activity of P. scutellarioides leaf extract from various variants and different solvents on sunscreen, skin lightening, and anti aging activities. The best extract is formulated in gel dosage form. Each P. scutellaroides leaf was extracted using ethanol, ethyl acetate, and hexane as solvents. The obtained extract was assessed for Sun Protecting Factor (SPF), UVA Protection grade (PA), antioxidant activity, and inhibition of tyrosinase, collagenase, elastase, and hyaluronidase. Determination was conducted in vitro using spectrophotometric methods. The highest sunscreen activity was observed in the ethanol extract Va (Va-ET), which exhibited SPF and PA values of 25.618±0.265, and 0.681±0.007 (star 3), respectively at a concentration of 100 ug/mL. The most significant skin-lightening activity was observed in the ethanol extract Vc (Vc-ET), with an IC50 value inhibiting tyrosinase of 39.059 ug/mL. Regarding the anti-aging activity of the extracts, as determined by their antioxidant activity and inhibition of collagenase, elastase, and hyaluronidase, the most promising extracts were obtained from ethanol extract Va (Va-ET) and ethyl acetate extract Va (Va-EA), with IC50 values of 79.734, 76.838, 143.384, and 122.467 ug/ mL, respectively. The Va-ET was formulated into a gel dosage form, and there was a significant effect of the gelling agent on the SPF value of the extract after formulation (p < 0.05). All extracts exhibit activity as sunscreen, skin lightening, and anti-aging, with the Va-ET showing the highest efficacy. Gelling agents significantly influence the SPF value of extracts after formulation into the gel dosage form. Among them, F3, formulated from the Va-ET of P. scutellaroides using Carbopol-940 as a gelling agent, exhibits the highest efficacy.

Authors: Psota Tetiana
Published: July 2024

Introduction. The article considers historical and legal origins of the foundations of the legal status of an individual in the European system of protection of human rights and freedoms as part of international legal reality of the region. The work examines the phenomenon of the legal status of a person in the European international legal reality in view of its modern normative regulation, protection mechanisms at the regional level and worldview sources of the evolution of its foundations.

Summary of the main research results. It was determined that the European international legal reality is a regional phenomenon of international law and includes universal and European regional norms and principles, sub-regional European international legal acts, legal culture and legal consciousness, moral value characteristics and institutions of European international law. The latter is closely related to the phenomenon of the European international legal reality in terms of reflecting the objective legal realm in Europe. The main purpose of the functioning of the European international legal reality is the protection of human rights and freedoms in the region. The regional system of protection of human rights and freedoms is an integral part of the European international legal reality and guarantees the fundamentals of the legal status of a person in Europe. The main principles of the legal status of a person in the European international legal reality are the general principles and standards of law, the moral, value and ideological characteristics of European international law. The genesis of the foundations of the legal status of a person in Europe and European identity in general is ancient Roman law, Christian dogmas and Germanic customs. It was the preservation of the main system-forming components of the Roman legal complex of principles and norms, the influence of Christian spirituality concept on the general European attitude towards the individual and the separation of the Romano-Germanic legal family features on the basis of Germanic phenomenon that became the basis of the modern European legal reality and laid the foundations of the individual's legal position.

Conclusions. At the current stage of the European international legal reality development, the legal status of a person is a fundamental category that emerged and evolved on the basis of centuries-old legal traditions of the region. Current regulatory and legal consolidation and functioning of regional mechanisms for the protection of human rights and freedoms is the result of historical and legal evolution of the foundations of the legal status of a person in Europe.

Published: July 2024

Background/Aim: The effect of surgical intervention on the quality of life and survival of patients presenting with metastatic breast cancer is a controversial issue. In this study, we aimed to reveal the survival, clinical, and pathological differences in patients with breast cancer who had metastatic disease at diagnosis and who underwent and did not undergo surgery for the primary tumor in our clinic and to evaluate the efficacy of surgical approach on the course of the disease.
Methods: In this retrospective cohort study, the data of patients with metastatic breast cancer in our clinics between January 2000 and June 2021 were retrospectively analyzed. The study included those with primary metastatic disease. The study did not include male patients, patients with primary non-breast tumors, those who died of causes unrelated to breast cancer, those who underwent surgery for metastatic foci other than the primary tumor, and those who could not be followed up regularly for various reasons. In our study, there were two groups; those who received only systemic therapy were assigned to Group 1, while those who underwent surgical treatment for the primary tumor were assigned to Group 2. The clinicopathological and survival data of the groups were examined.
Results: Surgical intervention was performed on 62 of our patients. The 4-year survival rates were higher than those who did not undergo surgery (Group 1: 59.6 [14.7%], Group 2: 83.5 [6%]). The comparison of the two groups showed a longer median survival in patients in Group 2 who underwent surgery, albeit not statistically significant (77 [11.23] months in Group 1 and 84 [18.91] months in Group 2 [P=0.16]).
Conclusion: In conclusion, our study showed that surgical treatment may have positive effects on survival.
Product Design Cost Estimation for Make-to-Order Industry: A Machine Learning Approach
Authors: Ma'ruf Anas , Leuveano Raden A. C. , Utama Rizky
Published: July 2024

This research addresses the need for accurate design cost estimation in the Make-To-Order (MTO) industry. The complexity of product customization is key to differentiation. While many studies focus on manufacturing cost estimation, few explore design cost estimation. To improve the accuracy of design cost estimation, this research proposes a new cost driver based on design features available in Computer-Aided Design (CAD) data. The design feature is analyzed to the actual industry cost using machine learning methods, including Artificial Neural Networks (ANNs) and Support Vector Regression (SVR). The cost drivers identified as significant consisted of twenty-six 3D CAD features and four 2D CAD features. The results showed that the ANN models outperformed the SVR models in correctly estimating product design costs, as evidenced by the high R2values in the training and testing phases. The proposed method allows early identification of cost drivers, a significant advantage at the order initiation stage when detailed design features are often ambiguous. The novelty of this research is the use of 3D CAD technology for cost estimation, which quantifies costs based on product design complexity, providing valuable insights into the impact of design adjustments on costs early in the design process. Doi: 10.28991/ESJ-2024-08-03-022 Full Text: PDF

Authors: Wijitkosum Saowanee , Sriburi Thavivongse , Krutnoi Luechai
Published: July 2024

Biochar is a value-added product that can be used for many purposes, particularly for environmental and agricultural purposes. In this study, pyrolysis at 450–500 °C was used to upgrade urban waste such as disposable bamboo chopsticks (DBCs) into biochar. The properties of DBC biochar were analyzed, and the biochar was subsequently used to cultivate Romaine lettuce to assess its potential as a soil amendment. Its properties, including specific surface area (SSA), pore size, pore volume, pH, cation exchange capacity (CEC), contents of carbon (C), hydrogen (H), nitrogen (N), oxygen (O), macronutrient content, and the atomic ratio of H/C, O/C, (O+N)/C, and C/N, were analyzed. The experimental pots consisted of four treatments, each with ten replicates: unamended soil (TC), soil amended with 10% (w/w) vermicompost (TV), soil amended with 10% vermicompost mixed with 1.5% biochar (TVB1.5), and soil amended with 10% vermicompost mixed with 2.5% biochar (TVB2.5). Fundamental physicochemical soil properties and plant yield (plant height, leaf width, number of leaves, and fresh weight) were investigated. The results indicated that the DBC biochar was neutral (pH 6.80) and had a high CEC (10.86 cmol/kg), 66.80% C, 3.76% H, 25.93% O, and 0.61% N. It had mesopores (39.077 Å), a large SSA (0.542 m2/g), and a pore volume of 0.005 cc/g. The biochar exhibited high aromaticity and hydrophobicity. Based on these results, the DBC biochar has the potential to be used as a soil amendment: it significantly enhances soil quality and increases plant yields. The application of 2.5% biochar resulted in the highest yield. Doi: 10.28991/ESJ-2024-08-03-07 Full Text: PDF

Kazakhstan’s renewable energy policy and development potential: Focus on Solar Energy
Authors: Yoon Youngmin ,   The Korean Association Of Area Studies
Published: July 2024

Expanding the development of renewable energy sources is recognized as one of the most important tasks in terms of responding to climate change and sustainable development. In addition, the increasing instability of the energy supply chain due to the Ukraine war emphasizes the importance of renewable energy in terms of energy security. Kazakhstan, a leading energy exporter among the FSU countries, has been promoting renewable energy development as a national policy for a long time, but has not shown significant results. In this study, Kazakhstan's strengths and limitations in the renewable energy sector, as well as opportunities for development, were examined by evaluating Kazakhstan's renewable energy development potential in three aspects - natural resources, institutions, and technology - with a focus on solar energy. Kazakhstan has relatively abundant solar energy resources, but the technological/industrial level for the development of the solar energy sector appears to be lagging significantly. However, the institutional level related to renewable energy appears to be higher than the world average, and some areas are higher than the OECD average. In order to expand solar energy development in Kazakhstan, cooperation between countries and attraction of investment are needed, which will be an opportunity for Kazakhstan.

Diversifikasi  Olahan  Ikan  merupakan  motivasi baru untuk memperkenalkan kepada masyarakat bahwa ikan yang biasanya dikonsumsi dalam bentuk digoreng, dibakar atau dimasak dalam keadaan utuh dapat dibuat makanan  yang  lebih  menarik  dan  tetap  bergizi  yang dapat  dikonsumsi  mulai  dari  anak-anak,  dewasa, sampai usia lanjut. Beberapa produk diversifikasi hasil perikanan antara lain: bakso ikan, nugget ikan, abon ikan, dan sosis ikan. Kampung Tablasupa Terletak di Distrik Depapre Kabupaten Jayapura, Provinsi Papua. Kampung Tablasupa termasuk kampung yang cukup berkembang di Kabupaten Jayapura dibandingkan dengan kampung-kampung lain. Kampung Tablasupa memiliki Industri Rumah Tangga Pangan (IRTP) yang di kerjakan oleh ibu-ibu dalam kelompok usaha. Usaha yang di jalankan adalah usaha diversifikasi produk ikan seperti nugget ikan. Usaha ini sudah di kembangkan sejak kurang lebih dua tahun. Dalam menjalankan produksi kelompok ibu-ibu IRTP Kampung Tablasupa masih menggunakan sarana prasana sederhana. Hal ini dapat memberikan dampak bagi kesehatan dan lingkungan. Tujuan dilakukan penelitian ini adalah untuk mengetahui Sanitasi dan Hygiene pada Pengolahan Nugget Ikan Industri Rumah Tangga (IRT) di Kampung Tablasupa Distrik Depapre, Kabupaten Jayapura, Papua. Data diperoleh dari hasil wawancara terhadap ibu-ibu pelaku usaha menggunakan angket dan pengamatan langsung proses pembuatan nugget ikan. Hasil penelitian menunjukkan bahwa usaha nugget ikan ini masih dalam skala industri rumah tangga yang pengolahannya dilakukan sendiri oleh ibu-ibu dalam kelompok usaha. Industri ini masih sederhana dan pengolahan nugget ikan yang dilakukan masih belum memenuhi standar karena tidak di dukung dengan sarana prasarana yang baik, seperti lokasi dan lingkungan yang sesuai, gedung yang permanen, ketersedian air bersih yang cukup, dan kesehatan para karyawan. Sehingga usaha yang dilakukan ini belum memenuhi standar sanitasi dan higiene baik dari segi sarana prasarana dan karyawan atau pekerja.

Proses budidaya perikanan memerlukan daya dukung untuk menjaga kualitas air agar menghasilkan hasil yang maksimal dalam proses budidaya. Budidaya perikanan mulai berkembang pada skala kecil (urban farming) yang dimana bertujuan untuk ketahanan pangan mandiri. Hal tersebut memerlukan solusi untuk menjaga kualitas air yang bertujuan meningkatkan pertumbuhan, kelangsungan hidup dan mencegah aroma yang tidak sedap muncul dari kegiatan budidaya. Menjaga kualitas air bisa dengan penggunaan filtrasi atau sistem resirkulasi pada kegiatan budidaya. Artikel ilmiah ini menggunakan metode studi kepustakaan (library research) dengan pendekatan deskriptif kualitatif yaitu dengan menggunakan metode analisis isi. Media filter terbagi dalam mekanis (kapas, dacron), biologis (bio ball, ceramic ring), dan kimiawi (karbon aktif, batu zeolite). Penggunaan berbagai jenis media filter berpengaruh terhadap kualitas air, pertumbuhan, dan kelangsungan hidup ikan. Penggunaan sayur sebagai filtrasi tambahan juga berpengaruh terhadap kualitas air.
“RESOLVI APRENDER ITALIANO DE VERDADE”: COMPLEXIDADE E AQUISIÇÃO DE SEGUNDA LÍNGUA POR UMA FALANTE NATIVA DE VÊNETO
Authors: Queiroz Marília Mesquita
Published: July 2024

Neste trabalho, busca-se verificar evidências de teorias de aquisição de segunda língua (ASL) na narrativa de uma falante nativa de Vêneto sobre suas experiências de aprendizagem de italiano e português. Partindo da ideia de língua como um sistema adaptativo complexo (Larsen-Freeman, 1997; Larsen-Freeman e Long, 2014; Paiva, 2013; Rokoszewska, 2014) e entendendo a ASL como um processo que pode ser explicado a partir de teorias aparentemente antagônicas, são destacados, na narrativa, pontos que envolvem aspectos como língua e prestígio social (Bagno, 2006), parâmetros linguísticos, aprendizagem formal versus informal, afeto (Krashen e Terrell, 1998) e uso de artefatos culturais (Vygotsky, 2007). A análise mostra que, em seu processo de aquisição, a aprendiz utiliza estratégias que podem ser caracterizadas como típicas de teorias ambientalistas, inatistas e sociointeracionistas, cujos preceitos surgem, a princípio, em oposição umas às outras. Dessa maneira, o processo de aprendizagem da narradora pode ser caracterizado como complexo, visto que envolve elementos típicos dessas diferentes teorias de aquisição de segunda língua.
Brasil CEM Covid

Em 8 de janeiro de 2021, eu e um grupo de valorosos médicos tomamos posse como os novos diretores da Associação Médica Brasileira (AMB). Eram tempos difíceis, por conta do advento da Covid-19. A doença já tinha matado quase 195 mil brasileiros em 2020, e os números alavancaram dia após dia.
Naquele dia, os gestos efusivos, típicos de uma solenidade de posse, foram substituídos por um visível ar de preocupação. A situação exigia. Na mesa solene, além de mim – na condição de novo presidente da AMB – só estavam Miguel Roberto Jorge, representando a antiga diretoria, e José Luiz Gomes do Amaral, presidente da Associação Paulista de Medicina (APM). De forma on-line, outros 300 médicos acompanhavam a cerimônia. E eu, encabeçando uma entidade de tamanha representatividade, como é a AMB, só tinha um pensamento: “É preciso fazer alguma coisa”. E tinha a convicção de que, como médicos e como instituição, podíamos fazer.
Diante do caos em que se encontrava o Brasil no princípio de 2021, se fazia necessário ter a capacidade de enxergar sem filtros a nossa realidade, considerar as consequências de nossas palavras e ações e fazer bons julgamentos e escolhas. Assim, colocando a Ciência como norte, nasceriam, a partir dali, muitas iniciativas promissoras.
Uma das primeiras foi a Força-Tarefa AMB, que atuou em Manaus (AM) e Porto Velho (RO), em um dos momentos mais emblemáticos da pandemia, marcado pela falta de oxigênio hospitalar e colapso do sistema de saúde na capital amazonense. Em seguida, tive a ideia de criar o Comitê Extraordinário de Monitoramento Covid-19 (CEM COVID_AMB), ação realizada em conjunto com as Sociedades de Especialidade do País, que, de tão marcante, foi levado ao título deste livro.
O CEM COVID_AMB se tornou um farol naqueles dias sombrios, compartilhando informações seguras e alinhadas à Ciência, aos médicos e à população. A nossa meta era o paciente e a sua segurança, sempre embasando nossas declarações nas melhores evidências científicas. Foram muitos encontros semanais, muitos especialistas atuando em várias frentes e muitas declarações oficiais dadas aos mais diferentes veículos de comunicação. A Ciência era a nossa maior arma para combater as milhares de fake news que surgiram pelo País, envolvendo questões como vacinação, cloroquina e hidroxicloroquina. Daí a importância deste trabalho, que revisita esse momento recente de nossa história e ainda de tão vívida memória, visto a partir do olhar e das ações da Associação Médica Brasileira. Temos o dever de não esquecer aqueles dias de luta e de luto. Portanto, que esta obra, escrita quase no calor dos acontecimentos, seja um antídoto e este esquecimento.

Published: July 2024

Ischemic Heart Disease (IHD) remains a significant cause of morbidity and mortality worldwide. We present a case report of a 54-year-old individual presenting with symptoms suggestive of IHD, including palpitations and chest heaviness. Utilizing a Spandan device at home, the patient detected anteroseptal and lateral wall ischemia, prompting consultation with a cardiologist. Subsequent diagnostic evaluations revealed Left Ventricular Hypertrophy (LVH), concentric LVH, regional wall motion abnormality, and Grade I diastolic dysfunction. Hypertension and dyslipidemia were identified as prominent risk factors, with additional findings of carotid artery disease. Management strategies included antihypertensive medications, lipid-lowering therapy, and lifestyle modifications. This case underscores the complexity of diagnosing and managing IHD, highlighting the importance of comprehensive assessment and multidisciplinary care in optimizing patient outcomes.
Comparison between abdominal core muscle strength in males with and without frozen shoulder: A pilot study
Authors: Juwayriah Nadim Dalvi  , Bharati Dileep Asgaonkar
Published: July 2024

Background: The impact of adhesive capsulitis starts from the structures surrounding the shoulder complex and extends to overall deconditioning and affects neuromuscular control due to reduced daily living activities which may be passed along further in the kinetic chain. Context: Studies show there may be a certain link between core muscle activation and shoulder function, however, the literature is scanty in this regard. Aims: To compare the abdominal core muscle strength in males with and without frozen shoulder. Settings and Design: In this observational comparative study, 20 males (40-60 yrs) from a tertiary care hospital visiting the physiotherapy department for the treatment of frozen shoulder were included along with age, Body Mass Index (BMI) and Waist to Hip Ratio (WHR) matched healthy controls. Methods and Material: Abdominal core muscle strength was measured using a pressure biofeedback unit while progressive limb loading was performed. Statistical analysis used: The ordinal data was compared using SPSS Version 24 and Man Whitney U and Wilcoxon W were obtained. Results: The abdominal core muscle strength of male patients with frozen shoulder was weaker compared with healthy controls (p > 0.0001) Conclusions: The abdominal core muscle strength was significantly weaker in the males with frozen shoulder compared to age, BMI and WHR matched healthy controls. Thus Inclusion of core muscle strengthening in the rehabilitation of patients with frozen shoulder may lead to better outcomes in rehabilitation.
