Linear Birefringence in Single-Mode Optical Fiber
Authors: Mohammed M.
Published: October 2023

The components of linear birefringence are essentially linear frequency dependence, Shape birefringence depends strongly on the frequency, for lower frequencies the value of Bc increases slowly with increasing ν, is an approximately constant, and give maximum value (0.46) for frequencies within the region 1.8 <V< 2.2. In contrast, when v increases at higher frequencies, the value of Bc steadily decreases. While it was shown that stress-related birefringence closely correlates with frequency, Bs has the same value as Bc and is (0.307) in the frequency value (5). This indicates that Bs contributes to Bc for large v values when the majority of the guided mode is contained inside the core. The minor axis of the core should align with the highest compressive stress, causing more power travel in the cladding and widening the mode size as the v value decreases. The fact that changes take place in that regime and that the cladding’s stress-induced birefringence is the opposite of that of the core, that is, the main axis of the core elliptical experiences the greatest extent of the core compressive stress.
Vulnerable Patients with Inflammatory Bowel Disease
Authors: Potlach Tomas , Zimmermann Ellen
Published: October 2023

Crohn’s Disease and ulcerative colitis, collectively known as Inflammatory Bowel Disease (IBD), are conditions characterized by inflammation and ulceration of the intestines. This work aims to highlight disparities among vulnerable IBD populations using the OneFlorida Clinical Research Consortium, a data network housing claims and electronic health record information for more than 15 million patients in Florida. A retrospective analysis using data collected between 01/01/2012 and 06/30/2020 was performed using OneFlorida, and patients were identified using diagnosis and pharmacy codes for IBD. 10,578 patients met the inclusion criteria. Healthcare utilization (emergency department visits, inpatient stay, medications, procedures), disease severity (c-reactive protein, white blood cell count, hemoglobin, albumin), and outcomes (i.e., abdominal surgery) were assessed for patients of different ages, gender, ethnicities, races, and locations. Notably, adolescent and young adult (AYA) patients (ages 17-25) use significantly more corticosteroids than both the pediatric and older adult groups (p-values 0.005 and 0.0007). Contrary to prior literature, Hispanic IBD patients used more biologic medications compared to non-Hispanic White patients (p<0.0001), whereas non-Hispanic Black patients used more steroids (p=0.0004). These findings illustrate a need for targeted educational interventions to support these vulnerable populations.
Moral Guilt, Dirty Hands Dilemmas, and the Dark Ghetto
Authors: Dzubin Nephtali
Published: October 2023

The non-ideal conditions of the dark ghetto can force residents into dirty hands dilemmas: dilemmas in which a moral agent must weigh between two courses of action that are both wrong but not equally wrong. For instance, one might have to decide between stealing and survival. The moral remainder of having done such acts invokes feelings of guilt, shame, or regret within the moral agent who has committed the infraction, even if it was the right thing to do all things considered. Philosophers such as John Rawls, Tommie Shelby, Allan Gibbard, Bernard Williams, and Patricia Greenspan have analyzed theories of justice, political philosophy, morality, moral emotions, and moral dilemmas. However, it has not yet been researched how moral remainder, specifically moral guilt, from dirty hands dilemmas are experienced by residents of the dark ghetto. Given that deontology, or duty ethics, is an ethical system that validates dirty hands dilemmas as genuine cases, a deontological approach is used to argue that guilt is appropriate for agents who emerge from dirty hands dilemmas having done things that are usually considered wrong.
Feminine Knowledge in the Digital Age
Authors: Ray Gabrielle
Published: October 2023

Members of Generation Z are bombarded daily with new innovations in technology within a rapidly globalizing world, leading to a constant shift in modes of connectivity and communication. The new wave of social media, especially TikTok and Instagram, arrives in parallel to increasing social awareness of previously taboo topics, like the focus of this research—pregnancy and childbirth. Women’s health issues, especially including the topics of menstruation, sex, pregnancy, and childbirth, were hardly spoken about publicly less than a decade ago. However, this is changing, and there is a growing number of women influencers using internet platforms to normalize conversations surrounding women’s health. Using an interview-based methodology, this research seeks to gather a better understanding of opinions on social media as an avenue for women’s health knowledge, and to answer questions about how the sharing of women’s health content on social media affects young women along with what this content reveals about the societal understanding of pregnancy and childbirth. This article primarily includes opinions and commentary from young female students at the University of Florida, in addition to some supplemental viewpoints from women’s healthcare providers. These diverse perspectives produce a more multifaceted understanding of how social media can be so impactful and therefore why it is able to shape perceptions of a condition such as pregnancy.

How the El Sistema Inspired Programs, Miami Music Project and the Youth Orchestra of Los Angeles, Directly Impact the Underserved Youth of Miami and LA
Authors: Florez Juan
Published: October 2023

This research is in the form of a collective case study focused on the Miami Music Project (MMP) and the Youth Orchestra of Los Angeles (YOLA). This study explores the various functions and goals of these El Sistema-inspired programs, and how they directly serve and impact under-represented communities. It also highlights the impact on the youth’s future and what these experiences tangibly and indiscriminately provide for their futures, be it beneficial or detrimental. This will also briefly touch on how MMP and YOLA’s approach to training young musicians subverts the idea of instrumental training typically being perceived as an activity only for those with few social and financial restrictions. Through virtual, individual interviews with various people that were either current alumni of these programs, recent graduates of college age, or adults in the field, their responses were recorded. This allowed for a holistic view of how these programs serve their students, thus resulting in answers that are representative of a larger population. Results showed commonalities between responses that trended towards highly positive results from being students in MMP/YOLA. In conclusion, this study clearly demonstrates that these programs have left positive, tangible impacts on their current and former students.
Féar Gortach
Authors: DeLeon Sophia
Published: October 2023

Folklore, as an ever-changing set of stories and traditions, provides valuable insight into the emotional and cultural impact of historical events. In Ireland, one can find an excellent case study in the evolving stories of the Féar Gortach. Also known as Hungry Grass, this particular Irish legend centers around patches of earth that instill intense feelings of hunger in those who cross it. Traditionally characterized as the doing of fairies, the legend began to see a cultural shift in the latter half of the nineteenth century following the tragedy of the Great Hunger. Beginning in 1845, the Great Hunger, otherwise known as the Irish Potato Famine, was a period of mass starvation and emigration in Ireland, brought about by the repeated failure of the potato crop due to agricultural disease. In the wake of this national tragedy, the legend of the Féar Gortach began to change. This paper examines how stories of the Féar Gortach were used to memorialize and process the Great Hunger in Ireland, drawing upon the imagery of funerary rites and nineteenth century famine walls in order to produce a uniquely Irish means of grappling with the tragedy.
Designing, Making, and the Body Intuitive
Authors: Castaño Urrea Catalina , Hailey Charlie
Published: October 2023

Embodied thinking, also termed ‘corporeal intuition,’ is the ability of the body to hold knowledge, be creative, and be active participants in the making process. This model challenges the idea that to make is to translate something that exists only in the mind into something that exists tangibly outside of the human body. Rather, the experience of making is an integral relationship between mind and body, the body and object of work, and the hand and material. Through a series of ceramic and woodworking exercises, each with increasing scales and complexities, this research explores experiences of making to understand how the material is an active part of the thinking and making process and then speculates how this process relates to architectural education. Research methodology tracks each exercise’s steps from beginning to end, and then rigorously analyzes the roles that each material’s properties play in the process. Thinking through making raises architecture students’ awareness of all the forces that are part of a design project from concept through to final built work, and the final phase of this research looks at how specific exercises (derived from this project’s methodology) foster embodied thinking for a more holistic design process.
Loss of Progranulin Results in Increased Pan-Cathepsin Activity
Authors: Abigail Anderson  , Drew Gillett  , Jakes Boles  , Rebecca Wallings  , Malú Tansey
Published: October 2023

Mutations in the progranulin (PGRN) encoding gene, GRN, cause familial frontotemporal dementia (FTD) and neuronal ceroid lipofuscinosis (NCL) and PGRN is also implicated in Parkinson’s disease (PD). These mutations result in decreased PGRN expression. PGRN is highly expressed in peripheral immune cells and microglia and regulates cell growth, survival, repair, and inflammation. As well, PGRN is implicated in regulating lysosome function, however, the exact role of PGRN in lysosomal function and how this contributes to inflammation and degeneration is not entirely understood. To better understand the role of PGRN in regulating lysosome function, this study examined how loss of GRN impacts lysosomal and cathepsin activity. Using mouse embryonic fibroblasts (MEFs), immunocytochemistry and immunoblotting assays were performed to analyze fluorescent signal from LAMP1 (lysosomal marker) and BMV109 (marker for pan-cathepsin activity). GRN-/- MEFs exhibit increased expression of pan-cathepsin activity relative to GRN+/+ MEFs, and significantly impacts expression of LAMP1. The significant increase in pan-cathepsin activity in the GRN-/- MEFs confirms that PGRN loss does alter cathepsin expression, which may be a result of compensatory mechanisms happening within the cell. Further investigations will include assessing LAMP1 and BMV109 expression in microglia from GRN-/- mice, in the hopes of understanding the role of PGRN in lysosomal function in immune cells of the central nervous system and the diseases in which it is implicated.

Objectives This study aims to determine the factors affecting the sense of dignity in patients with psychiatric disorders during hospitalization in a psychiatric hospital in Tehran, Iran. Methods This is a cross-sectional study. Participants were 253 adult patients with psychiatric disorders admitted to Iran Psychiatry Hospital, who were selected by a convenience sampling method. A researcher-made questionnaire was used to assess the patients’ sense of dignity. To analyze the collected data, independent t-test, Pearson’s correlation test, ANOVA, and linear regression analysis were used. Results There was a significant correlation between age and a sense of dignity (r=0.266, P<0.001). Patients with an educational level above a diploma had a lower sense of dignity than those with a diploma or lower (3.01 vs. 3.15, P=0.023). Patients who were aware of their own disease diagnosis had a lower sense of dignity than those who were not aware (3.06 vs. 3.17, P<0.001). The linear regression model showed the significant ability of age, knowledge of own disease diagnosis, and educational level to predict the sense of dignity. Conclusion Psychiatric patients’ age, educational level, and knowledge of own disease diagnosis can predict their sense of dignity during hospitalization. Healthcare providers and policy makers should consider these factors during interventions to improve the sense of dignity in these patients

Background: Clinical evidence supports the influential role of genetic factors and intracellular signaling pathways in physiological cardiac hypertrophy. This study aimed to assess the response of the PI3K/mTORc1 signaling pathway in cardiac tissue to resistance training in obese rats with Type 2 Diabetes (T2D). Materials and Methods: A total of 21 male Wistar rats (Mean±SD weight: 220±20 g) were obese by 6 weeks High-Fat Diet (HFD) and randomly assigned to 1) non-diabetic, 2) control T2D, and 3) exercise diabetic groups. T2D was induced by intraperitoneal injection of streptozotocin (30 mg/kg) for diabetic groups. The exercise group did the resistance exercise program (5 times per week for 6 weeks). After exercise training, PI3K and mTORc1 expression in the left ventricle and the ratio of the left ventricle to heart and heart to body weight were compared between groups. The obtained data were compared by 1-way Analysis of Variance (ANOVA) (P<0.05). Results: Induction of diabetes resulted in significant decrease in all mentioned variables in control diabetic to non-diabetic rats (PI3K; P=0.021, mTORc1; P=0.004, left ventricle/heart weight; P=0.045, heart/body weight; P=0.035). Significant increase was observed in all variables (PI3K; P=0.028, mTORc1; P=0.015, left ventricular/heart weight; P=0.002, heart/body weight; P=0.001) in response to resistance training compared to the control rat. Conclusion: Based on our results, cardiac hypertrophy in studied diabetic rats can be attributed to improved PI3K/mTORc1 signaling in response to resistance training. Exploring the exact mechanisms responsible for these changes in response to exercise requires further molecular-cellular studies.
Procedure for the seismic analysis of reinforced concrete tunnels using the finite elements method
Authors: Felix-López Nelson  Saint , Aguilar Jorge  Rondón
Published: October 2023

Considering the sensitivity of reinforced concrete tunnels moving on soft soil foundations to earthquake action, some degree of damage to earthquake action, and the uncertainty of tunnel dynamic performance under earthquake action, an analysis procedure based on the finite element method is proposed, which considers ground deformation caused by earthquake action. The analysis can obtain the stress-strain states produced in the tunnel structure as a consequence of the seismic action, which are compared with the kinematic procedure for the seismic analysis of tunnels.
Data mining to aquifer vulnerability assessment

Published: October 2023

The vulnerability map of aquifer pollution is a part of the early warning system to prevent the deterioration of groundwater quality. The weighted index overlay methods are commonly used to map aquifer vulnerability, but they have a series of drawbacks, indicating the need to apply alternative methods that introduce the least number of a priori considerations in the parameters processing and allow a more accurate interpretation of the final results. The purpose of this study is to use data mining techniques for cluster analysis to evaluate the vulnerability of groundwater pollution in the Almondarez Vento Karst Basin in Havana Province, Cuba, and compare the results with those obtained using the RISK method, which is a weighted index overlay method to study karstic aquifers. The variables selected to apply this unsupervised classification technique were: aquifer lithology, topographic slope of the terrain, soil attenuation index to pollutants, fault density per km2 and presence of direct infiltration zones. The cluster analysis achieved greater spatial discrimination and definition of areas with different degrees of vulnerability, demonstrating its high resolution power.

In Mexico, one of the main sources for agricultural irrigation is groundwater, which irrigates approximately 2 million hectares, accounting for 75% of the country's rural and urban water volume. These water resources are affected by industrial waste and residual pollutants, as well as the leaching of chemical substances from agricultural soils. In order to evaluate the physical and chemical characteristics of groundwater, this study was conducted in Zacoalco de Torres and Autl á n de Navarro. Sampling was conducted during the dry and rainy seasons in 2017. The sampling locations were deep wells and water wheels. A total of 48 samples were obtained from two sites. In each sample, pH value, anion and cation, electrical conductivity (EC), residual sodium carbonate (CSR), sodium adsorption ratio (SAR) and hydrogeochemical classification were analyzed. The underground water of Zacoalco is mostly chlorinated-magnesic and in Autlán it is bicarbonate-magnesic with medium and low concentrations, so it is recommended for irrigation. With respect to salinity, Zacoalco has 40% high salinity water in dry conditions and 66% medium salinity water in rains; Autlan has 75% high salinity water in dry and 75% medium salinity water in rainfall, so its use shows moderate restrictions.

Published: October 2023

Apresenta esse caso, um interesse particular pois simulou blastoma ósseo do tipo malígno, diagnóstico que o exame histopatológico modificou, dando nova orientação terapêutica permitindo outro prognóstico. Permanecerá o doente em observação o que se justifica principalmente pelo fato já referido de se considerar tal lesão, no adulto, com aspécto local de retículo-endoteliose, que poderá se generalizar e se acompanhar ou não de síndrome de Hand-Christian-Shüller. Histologicamente o nosso caso recapitula o quadro verificado em tôdas as observações publicadas, não tendo sido encontradas no entanto, células xantelasmizadas. Áreas de necrose, fibras de reticulina e mesmo as lesões vasculares descritas nas manifestações cutâneas, foram verificadas. Chamou-nos a atenção a imagem de alguns elementos que se mostram muito semelhantes às células de Steinherg, da linfogranulomatose maligna.  O fato de não se verificarem modificações imediatas da lesão após o tratamento pelas irradiações já foi assinalado em outras observações. Aparecem, no entanto, algum tempo depois, determinando a cura. Serve essa observação para confirmação da conduta acertada e moderna que orienta e ressalta a importância da patologia, companheira inseparável da clínica, no diagnóstico e tratamento das enfermidades. Somente com esse trabalho de colaboração pode-se assegurar orientação científica com resultados melhores para os pacientes.
Tumores das Glândulas Salivares

Published: October 2023

Nêste artigo focalizamos aspectos importantes dos tumores das glândulas salivares. No Serviço Nacional de Câncer, em 10.664 doentes ali registrados com ou sem lesão maligna, verificamos 45 casos de tumor de glândula salivar, distribuídos do seguinte modo: Parótidas: 25; Sub-maxilares: 10; Sub-lingual: 4; Glândulas salivares do lábio: 5; Glândulas da abóbada palatina: 1. Essa estatística supera a da Clínica Cirúrgica do Prof. José Arce, de Buenos Aires, que só encontrou 4 casos de tumores mixtos de glândula sub-maxilar em 25 mil doentes ali operados, bem assim a da Clínica Dockerty e Mayo, que em 1 milhão de doentes examinados encontraram tão somente 51 casos de idêntica localização. Entre nós, há registros de alguns casos de tumores das glândulas salivares, como os de Alfredo Monteiro, Jorge Morais Grey, Mariano de Andrade e Pedro Moura, tendo este publicado os que observou no Serviço do Prof. Brandão Filho. Pelos dados acima referidos, fica realçada a pouca frequência dos tumores das glândulas salivares.

Effets des Polysaccharides sur le Sarcôme de la Souris
Authors: Gosselin W.
Published: October 2023

Depuis assez longtemps, les chercheurs avaient remarqué Tantagonisme, en même temps qui raffinité, qui semblent exister entre la cellule cancéreuse et rinfection. Chez Tanimal, les greffes s’infectent facilement avec nécrose consécutive; on était justifié de penser que les bactéries sont porteuses d’une substance qui mise en présence de la cellule cancéreuse provoque sa nécrose. En 1943, Shear et ses collaborateurs (1) parvenaient à isoler dans une culture de bacille prodigiosus (Serratia Marcesceus) un facteur qui, injecté à des souris porteuses de sarcôme, produisait dans un délai de 24 heures, une nécrose hémorragique considérable au niveau de la tumeur. L’analyse chimique et électrophorétique de ce produit ont révélé qu’il s’agissait de polysaccharides renfermant du glucose, méthylpentose, du glucosamine et des traces de phospholipides (2-3-4). Une méthode de dosage fut établie avec comme résultat qu’une dose de 25 à 50 microgrammes est nécessaire pour produire um résultat positif chez la souris porteuse du sarcome 37 d’une semaine. A cette dose la mortalité chez la souris varie entre 25 et 50 %, en dedans de 24 heures. A la suite d’expériences cliniques chez des patients atteints de cancers incurables, il a été donné de constater que la souris pouvait tolérer une dose mille fois plus forte que Têtre humain, si on se base sur le poids (5-6). Si nous pouvions réduire la toxicité actuelle des polysaccharides de façon telle que les patients puissent supporter une dose égale quant au poids, à celle qui est effective chez la souris, nous aurions peut-être en main une arme contre le cancer. C’est pourquoi depuis septembre 1948, nous avons entrepris des travaux afin de savoir s’il serait possible d’obtenir une réduction de la toxicité des polysaccharides, sans leur enlever leur pouvoir nécrotique et hémorragique sur la cellule néoplasique.

El uso del mantenedor de espacio en la dentición decidua y mixta es de relevante importancia, ya que ayuda a prevenir la instalación de maloclusiones, incluidas aquellas derivadas de la pérdida temprana de dientes, manteniendo el espacio necesario para la erupción de los elementos permanentes. Este trabajo tiene como objetivo relatar un caso clínico en una paciente de sexo femenino de 10 años de edad. La paciente acudió a la Clínica Odontológica Infantil de la Facultad de Odontología de la UFAM con la queja principal de insatisfacción con su sonrisa. Durante la anamnesis, la madre relató un trauma en los elementos 51 y 61, y el examen clínico demostró una retención prolongada de dichos elementos y maloclusión. Después de la exodoncia de los elementos retenidos, debido al retraso en la erupción de los elementos permanentes, se indicó la fabricación de un aparato mantenedor de espacio, con fines estéticos y de prevención parafuncional. Para ello, se utilizó una Placa de Hawley y, con fines estéticos, se agregó un diente de acrílico. Después de un período de 5 meses de uso del aparato, los incisivos centrales y laterales irrumpieron de forma natural en la boca. A partir de este enfoque de tratamiento, se logró mantener el perímetro del arco superior, el espacio necesario para que los elementos permanentes erupcionen, evitando inclinaciones dentales y pérdida de espacio, sin la aparición de hábitos bucales deletéreos y parafuncionales, y maloclusiones futuras más complejas, así como el bienestar estético de la paciente.

An Examination of Moroccan EFL Teachers' Use of Digital Tools in the Classroom: The Case of Teachers and School Related Factors
Authors: Laachir Abdelouahed , Bousmaha Ghita , El KARFA Abderrahim
Published: October 2023

The aim of the present study is to examine the extent to which teachers’ attitudes and beliefs, access, training, and support influence the integration of computers in the classroom. Since this study deals with the variables that affect the incorporation of computers in the classroom, a cross-sectional research design was adopted to describe the relationship between those variables. A questionnaire was administered to 61 Moroccan high school teachers of English. The results of this study illustrate that teachers’ beliefs and attitudes did not seem to be an obstacle because the vast majority of teachers have positive attitudes towards computer use in the classroom; (b) access to computers and technological tools was found to be the most factor that stopped teachers from using computers in the classroom; (c) in addition, training was explored to be another factor that affects the integration of computers. A very small minority of teachers reported that they were offered training opportunities; (d) this study continued to prove that support was another obstacle to computer use. Most teachers reported the absence of technical support to fix technical problems by the school system.
L’antiquaire comme discours politique : représentations et emplois de l’État des origines chez François Hotman et ses critiques
Authors: Paoli Lorenzo
Published: October 2023

En discutant de l’usage des sources et de leurs implications politiques à l’intérieur de la Francogallia de François Hotman, l’auteur propose de rejoindre la problématique de la représentation de la communauté protestante au travers de l’usage du passé pendant le conflit civil. Les instruments techniques et extra-techniques qui sembleraient dénoncer une histoire moderne, voire critique, peuvent être compris comme des moyens idéologiques pour imposer une représentation de la communauté nationale qui dépasse les factions : une communauté nationale ancienne qui soutiendrait toutefois les positions du parti protestant. Grâce à l’antiquaire, les interrogations sur les polices, les langues et les institutions des origines gauloises, franques et germaniques du Royaume sont également des propos politiques.

El presente estudio investiga la integración de la Inteligencia Artificial (IA) en la Educación para el Desarrollo Sostenible (EDS), evaluando oportunidades y desafíos. La convergencia de la IA y la EDS ofrece oportunidades clave, como la personalización del aprendizaje, eficiencia en la gestión educativa y el desarrollo de contenido adaptativo. El propósito fundamental de este estudio consistió en examinar y evaluar las percepciones de los alumnos de una Institución de Educación Superior en relación con el uso, las potencialidades y las dificultades asociadas con la IA en su formación y proceso de enseñanza. Para esto, se implementó una metodología con un enfoque cuantitativo, utilizando un diseño no experimental descriptivo a través de una encuesta. Este diseño metodológico proporciona la capacidad de explorar de manera detallada las prácticas existentes, las percepciones de los actores principales y el análisis de los datos para determinar el impacto de la IA en la educación para el desarrollo sostenible. Los resultados identificaron desafíos, como la brecha de conocimiento entre estudiantes y la resistencia a la adopción de la IA en el ámbito de la educación para el desarrollo sostenible, además de la falta de conciencia sobre las capacidades reales de la IA, lo cual destaca la necesidad de programas educativos. En conclusión, se observó la necesidad de reducir la brecha de desconocimiento mediante la realización de capacitaciones centradas en la IA, con el objetivo de que los estudiantes adquieran un mayor conocimiento sobre las ventajas que esta tecnología puede aportar a su formación académica. Asimismo, se recomienda que los profesores utilicen, aunque sea de manera limitada, herramientas basadas en IA en su proceso de enseñanza. Este enfoque contribuirá no solo a ampliar el conocimiento de los estudiantes, sino también a enriquecer la calidad y la efectividad de la educación proporcionada.

Background: Pressure sores are an ancient medical problem; were even found in autopsies of Egyptian mummies. Sacral pressure sore is more common among paraplegic and bedridden patients. The principle of treatment is excision of all dead & devitalized tissue including scars, underlying bursa, and the involved bone, followed by durable coverage with Flap. Various flaps have been used to reconstruct the pressure sore, including Fasciocutaneous flaps, muscle flaps and free flaps. Among various local flaps, perforators based V-Y advancement fasciocutaneous flap is a reasonable and flexible option with good outcomes for sacral pressure sores reconstruction.
Objectives: The purpose of this study was to evaluate the outcome of perforator based V-Y advancement fasciocutaneous flap for sacral pressure sores reconstruction concerning the sociodemographic characteristics of the patients, defect size, and outcome of surgery.
Methods: This was a prospective observational study, conducted in the Burn & Plastic Surgery department of Rangpur Medical College Hospital, Rangpur over a period of three years from August 2018 to September 2021 through purposive sampling. Patients of all ages and sexes having grade IV sacral pressure sores were included in this study. In all cases, perforator- based V-Y advancement fasciocutaneous flaps were used. Surgical technique, patient demographics, and outcome were evaluated.
Results: A total of 30 patients were operated on. The age range was 18 – 65 years, among them 43.33% of patients were in the age range of 31 – 40 years. 80% of patients in this series were male. Traumatic paraplegia was the main cause of sacral pressure sore, and it was 70%. This study showed that in context to the length and breadth of the wound, a majority (30%) of the patients had a wound dimension of 71–90cm2. The smallest wound dimension was (5x6) = 30cm2 and largest wound dimension was (10x16) = 160cm2. Twenty-one sores that ranged from 6cm to 10cm were reconstructed with unilateral flaps and 09 sores that ranged from 11cm to 16cm were reconstructed with bilateral flaps. In this study, 06 (20%) patients had complications and all were managed conservatively. Three patients had infections and were treated according to the culture sensitivity report. Two patients had marginal flap necrosis at the vertical limb of Y which healed conservatively. One patient developed a seroma due to a blockage of the drain tube, which was resolved spontaneously. There was no flap loss in our study. The average follow-up period was one year. No recurrence of pressure sore during this period.
Conclusion: The simplicity of the surgical procedure, minimum or no morbidity in the donor area, and satisfactory outcome in terms of recurrence make this a reasonable option for the reconstruction of the sacral pressure sore.

Background: Type 2 diabetes Mellitus is a major growing health issue worldwide. There is a strong relation between iron parameters and type 2 diabetes mellitus. Iron metabolism can directly or indirectly affect the occurrence and development of type 2 diabetes.
Objectives: To observe serum levels in Type 2 Diabetes Mellitus patients.
Methods: This cross sectional study was conducted from to in the Department of Physiology, Rangpur Medical College, Rangpur. For this study, total number of 150 subjects were selected among them 75 non-diabetic healthy subjects were included in group-A and 75 Type 2 Diabetes Mellitus patients were included in group-B. The subjects of group-A were selected from surrounding community of Rangpur district and subjects of Group-B were selected from Diabetic Association and from Outdoor of Endocrinology Department, Rangpur Medical College and Hospital, Rangpur. For statistical analysis independent sample “t”test was performed by computer based software SPSS- 23.0 version for windows.
Results: Mean serum free iron concentration in Group A and Group B were 12.29±3.1 μmol/l and 15.24±6.8 respectively. Mean TIBC in Group A and Group B were 68.06±7.3 μmol/l and 56.89 ± 8.6 respectively. Mean serum ferritin concentration were 131±12.90 mg/ml and 170.50±15.1 respectively. The difference between serum iron, TIBC and ferritin between Group A and Group B were highly significant ( p _ 001 ).
Conclusion: The results obtained from this study suggests that serum iron and serum ferritin were increased and TIBC was decreased in T2DM patients as compared to healthy control.
