Objective. Endometriotic tissue implants rarely transform to malignant tissue, especially in a patient with a hysterectomy and bilaterally salpingo-oophorectomy. However, several cases with cancer arising from endometriosis after hysterectomy were reported in the literature. Hormone replacement therapy only with estrogen is a crucial risk factor for malignant transformation of persistent endometriotic tissue. Case Report. The present case demonstrates an endometrioid adenocarcinoma arising from persistent endometriosis tissue in a patient who was performed hysterectomy with bilateral salpingectomy 3 years ago. The histopathologic specimens of the previous surgery did not include any malignant tissue. After 3 years, she applied to the hospital with abnormal vaginal bleeding, and her histopathologic examination result found an ulcerated mass at the upper one-third of the vagina that is compatible with endometrioid adenocarcinoma. Conclusion. It is crucial to keep in mind the endometriosis history of the patient, to be able to diagnose cancer arising from endometriosis while evaluating the patient with a hysterectomy.

The old unreduced elbow dislocation is not very frequent, but when it is found, it is a challenge for every surgeon. We present a case of 65 years old man who came to the hospital with a dislocated elbow. After the first attempt to reduce, the elbow was mobilized in sling for 2 weeks, but during a small effort, the joint dislocated again. Another two orthopedic reduction were tried, followed by cast immobilization, but the elbow dislocated again. The patient presented in our service after two months from the injury with stiff joint in a vicious position. On imagistic examinations (Rx, CT, MRI), it was found comminuted fracture of coronoid process, posterior dislocation of olecranon and both collateral ligaments were torn. An open reduction was performed during which the joint surface was cleaned up, the anterior capsule was reattached to the coronoid process with an anchor, and then, collateral ligament was restored with the help of autograft, a gracilis muscle (bone fixed with two anchors). Postoperatively, the patient slowly began to mobilize the elbow with splint protection. After a year, the patient returned for follow-up; the function was completely restored and he had no pain.

Objective. Delirium is a temporary neuropsychiatric syndrome characterized by fluctuations in cognition and attention. Delirium is one of the most common complications seen in old individuals after orthopaedic surgery. With a high incidence, the clinical picture of delirium increases the length of hospital stay and increases healthcare-related costs. This study has aimed to systematically review the national and international studies that investigated the risk factors leading to delirium in geriatric patients after orthopaedic surgery and to perform a meta-analysis using the data reported by those studies. Materials and Methods. A preliminary literature review was performed on six databases. The following English keyword combinations were used including 'Orthopaedic Surgery', 'Geriatrics', 'Elderly', and 'Delirium'. The results of trials were evaluated with random or fixed effect model according to the heterogeneity. Statistical evaluation was performed by using Comprehensive Meta Analysis version 3 programme. Results. The total sample size of the studies included in the analysis was 892. In geriatric patients; who had undergone orthopaedic surgery and developed delirium, the random-effects model revealed a high-level, in the positive direction, and statistically significant (p<0.05) overall effect size of 5.21 (CI; 1.33-20.33) for gender, 1.33 (CI; 0.58-2.06) for age, 11.30 (CI; 4.70-27.12 for polypharmacy, and a low-level, in the positive direction, and statistically significant (p<0.05) overall effect size of 0.12 (CI; 0.05-0.27) for mini-mental state examination as the risk factors leading to the development of delirium. Conclusions. Advanced age, female gender, polypharmacy, and a mini-mental state examination score of 17-23 are major risk factors for the development of delirium after orthopaedic surgery.

Published: November 2021

Introduction. Gastric cancer remains among the top three digestive diseases with the highest mortality rates in the world. Treatment of gastric cancer is multidisciplinary, gastric resection being essential for the best result. Anemia is one of the most common comorbidities present in patients diagnosed with gastric cancer. Materials and Methods. This is a retrospective analytical study over a period of 6 years (2014-2019). It is based on 114 consecutive gastric resections for cancer performed by a single team using exclusively resection and reconstruction stapling methods. The study aims to investigate a correlation between the presence of preoperative anemia and the incidence of postoperative morbidity and mortality. Results. Preoperative anemia was found in 70% of patients, with about half of these patients presenting with mild anemia. Most postoperative complications were grade I and II according to the Clavien Dindo scale. Anemia was correlated with an increase in infectious complications, anastomotic leaks and secondary peritoneal abscesses, pancreatic complications after multivisceral resection and length of hospital stay. Conclusions. Preoperative anemia is a risk factor that exposes the cancer patient to an increased incidence of life-threatening postoperative complications. In addition, it also extends the length of hospital stay and costs. Therefore, special attention should be paid to the identification and reduction of anemia before extensive gastric surgery in order to obtain the best possible therapeutic result.

Authors: Khalil Hadeel Hazim , Raoof Saad M.
Published: November 2021

Textile-Reinforced Cement (TRC) was used in structural retrofitting and strengthening existing structures. While at present, recent studies have turned around using TRC as an independent structural element. This research presented an experimental study on the flexural behavior of TRC plates. Several parameters were taken into account, specifically, (a) the number layer of textile fiber materials (1, 2, and 3); (b) the configuration of the reinforcement (together or interface); (c) thickness of TRC plate (50, 70) mm. This study included preparing and testing twelve specimens; two specimens were un-reinforced, whereas the rest ten specimens were reinforced by dry carbon fiber textile. The results found that increasing the number of layers for both reinforcement configurations led to increased flexural capacity. Increasing the thickness of the plate has a negative effect on the flexural capacity for both reinforcement configurations. Finally, the interface reinforcement configuration with thickness 50 mm or 70 mm had higher flexural capacity than the specimens with together reinforcement configuration.

Authors: Pooja More
Published: November 2021

Coronavirus disease 2019 (COVID-19) is caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) which is a novel coronavirus. There is a constant increase in number of positive cases for COVID-19. The objective of this review is to study technology tools and sensors available for detection and diagnosis of COVID-19. COVID -19 pandamic has created surge demand for essential health care instrumentation, medicines along with technology and tools for proper control and management of corona virus. Diagnosing and screening of COVID-19 is possible using nucleic acid testing and CT scans. In this study, we have described Field-effect transistorbased graphene sensor and Plasmonic Photothermal(PPT) biosensor for highly accurate SARS-CoV-2 detection. A dual-functional localized surface plasmon resonance (LSPR) biosensor combining the photothermal effect and plasmonic sensing transduction is used for SARS-CoV-2 viral nucleic acid detection. FET based sensor for COVID- 19 used a graphene channel coupled to the SARS-CoV- 2 spike antibody with the efficient gating effect of the FET through phosphate -buffered saline (PBS; pH 7.4) buffer as the electrolyte covering. The aqueous solution-gated FET system detects SARS-CoV-2 based on electrical signal due to changes in channel surface potential. Industry 4.0 technologies such as Artificial Intelligence (AI), Internet of things(IOT) have helped in early detection and diagnosis. AI can build an intellegent platform with neural network for automatic monitoring and prediction of the spread of virus.IOT can assist in diagnosis and treatment of COVID-19 patients and can help in setting in advanced clinical work. Industry 4.0 technologies improve the working efficiency of the health care professional and provide better solution.

Authors: Sinha Shruti , Chaitanya K.V.
Published: November 2021

Folding eukaryotic DNA by chromatin is a vital process necessary for the proper function of DNA. This is achieved by the fundamental unit of chromatin, known as a nucleosome. The position of a nucleosome and its interaction with DNA plays a crucial role in regulating the vital processes involved in DNA function. Factors such as variations in nucleosome and its core structure and histone fold variations will help to understand nucleosome functions and their role in DNA replication, transcription, translation, posttranslational modifications, re-combinations and repair. The present review focuses on recent findings in understanding the variations in the structure and functions of nucleosomes across eukaryotes. Variations in the nucleosome organization and its assembly have also been discussed by stating the contribution of histone binding factors and chromatin assembly factors.

Authors: Goswami Rachna , Mishra Vijay Kumar , Dasu Veeranki Venkata
Published: November 2021

L-asparaginase (EC 3.5.1.1) is used for the treatment of acute lymphocytic leukemia and food processing of starch rich foods for reducing the acrylamide formation. In our current efforts, we have immobilized the purified glutaminase-free recombinant Lasparaginase II of Pectobacterium carotovorum MTCC 1428 from Escherichia coli BL21 (DE3) on glutaraldehyde activated chitosan beads. The purified recombinant L-asparaginase II has no partial glutaminase activity which is a pre-requisite to reduce the possibility of side effects during the course of anticancer therapy. In order to study the best conditions for the performance of free enzymes and immobilized enzymes, response surface methodology was used to optimize the pH and temperature of the process conditions. It was found that the most favorable pH and temperature for the free enzyme were pH 7.83 and 47.64°C while for the immobilized enzyme, the optimum pH and temperature levels were found to be 7.88 and 48.07 °C. Furthermore, the thermal and pH studies of free and immobilized enzymes were studied under various combinations of pH and temperature and finally the thermodynamic parameters of free and immobilized glutaminase-free recombinant asparaginase were evaluated.

“Cameralism” or “patrimonialism”: at the origins of Peter the Great’s reformation of higher management in Russia
Authors: Omelchenko N. A.
Published: November 2021

The article presents the author’s interpretation of Petrine reforms of higher management in Russia. The author of the article asks the question, how successful was the attempt made by Peter I to create a rational system of public administration in Russia according to Western models? Among the main features of Peter’s reformation, the author highlights the lack of a clear and well-thought-out plan for the reforms carried out by Peter I, most of which were mainly “experimental” in nature, were carried out hastily and were subordinated to the tasks of the ongoing war with Sweden. Based on the analysis of the transformations carried out at the beginning of the XVIII century in the system of higher administration, the author of the article concludes about the strengthening of the personal principle in public administration during the reign of Peter I, which casts doubt on the widespread opinion about the formation of a rational system of public administration during the reforms carried out by Peter I. According to the author of the article, the use of Weber’s concept of “patrimonialism” (“patrimonial bureaucracy”) as a special type of domination based on the principle of personal loyalty to the patrimonial ruler (monarch) may become more correct in this regard when describing the Peter’s administrative system.

Published: November 2021

The ability to exploit energy autonomously is one of the hallmarks of Life. Mastering such processes in artificial nanosystems can open unforeseen technological opportunities. In the last decades, light- and chemically-driven autonomous systems have been developed in relation to conformational motion and self-assembly. On the contrary, the autonomous exploitation of electrical energy remains essentially unexplored, despite being an attractive energy source. Herein we demonstrate the autonomous operation of an electrochemically-powered self-assembling nanomachine. Threading and dethreading motions of a pseudorotaxane take place autonomously in solution, between the electrodes of a scanning electrochemical microscope. This innovative actuation mode allows operating a molecular machine with an energy efficiency of 9%, unprecedented in autonomous systems. The strategy is general and can be applied to any redox-driven system, including molecular pumps that perform work repetitively. Ultimately, our study brings molecular nanoscience one step closer to everyday technology.
Social process in a voluntary organisation: a study of adult membership in the Scout Association of New Zealand
Authors:   , Kitay Gerald Bennett
Published: November 2021

This thesis examines social processes in a large, voluntary organisation. The investigation was concerned with the activities and retention of lower-level adult members in the Scout Association of New Zealand. The demographic, socio-economic and organisational background of members, their attitudes, and the organisational context within which activity occurs were examined with reference to the relationship of these variables with the satisfaction, commitment and participation of members. Particular attention was given to five organisational variables: size, communication, control, support and effectiveness. Attitudinal variables such as solidarity, ideology, prestige and orientation were also examined. It was found that the organisational variables were most clearly related to differences in satisfaction, commitment and participation. This was described firstly in terms of an association between larger size, better and more frequent communication, and higher levels of control, support, and effectiveness. The latter in turn was related to higher levels of satisfaction, commitment, and participation. Background variables, particularly age, also proved important. This suggested that the life cycle plays a part in voluntary association membership and activity. It was concluded that the main organisational variables are affected by the peripheral structural position of voluntary associations in New Zealand society. The sanctions available to senior officials are few and generally weak, and there is often little pressure to pursue some of the more intangible formal goals. Adherence to official procedures varies, with frequent blockages of control, communication and support. This results in considerable differences in the organisational environment within which members operate. The study was carried out over two years. Observation, semi-structured and unstructured interviews were used, as well as a lengthy questionnaire.
The Prevalance of Depression amongst People with Chronic Obstructive Pulmonary Disease on Long Term Oxygen Therapy
Authors:   , Mold Emma
Published: November 2021

Aim: To determine the prevalence of depression amongst people with chronic obstructive pulmonary disease (COPD) on long term oxygen therapy (LTOT) and examine the differences and relationships between depressed and not depressed patients to inform clinical practice. Methods: In September 2009 a cross-sectional point prevalence study of the total District Health Board (DHB) population of COPD patients on LTOT oxygen in a large urban area in New Zealand (NZ) was conducted. Depression was assessed using the self-completed Patient Health Questionnaire (PHQ-9). Additional clinical and demographic characteristics were obtained from hospital records and a self-completed questionnaire. Results: Sixty three patients (36 females, mean age 72) from the total population of 73 with severe COPD (forced expiratory volume in one second [FEV1] 37% predicted) completed the survey. PHQ-9 results indicate the total prevalence of depression was 54%; 95% CI 41.71-65.87. Twenty five percent of patients had mild depression and 29% had moderate to severe depression. One in six patients of those who screened positively was being treated for depression. No significant correlations or differences were found between the depressions scores and the demographic (age, gender, lives alone) or clinical (portable oxygen, time on oxygen, hospital admissions, pulmonary rehabilitation and FEV1) characteristics. Conclusion: This study provides new evidence regarding the prevalence of depression in NZ COPD LTOT populations. Depression symptoms and depression are highly prevalent in this patient population and there is evidence depression is undertreated. The PHQ-9 is a simple and effective tool community nurses can use for the initial screening of depression, which could improve the recognition and possible uptake of effective interventions to lessen the impact of depression in this population. The PHQ-9 is validated screening tool that should be used in further depression prevalence research with NZ COPD and other long-term condition populations to determine homogeneity across studies.
Megacolon tóxico, diagnóstico y tratamiento
Authors: Narváez Álvarez Carolina Misshell , Suazo Suárez Luis Felipe , Mera Morales Paulina Vanessa , Salazar Vásquez Natalia Marina
Published: November 2021

El megacolon tóxico es una grave complicación de las enfermedades inflamatorias intestinales que altera el funcionamiento del intestino grueso. Aunque los raros reportes del origen de esta condición deriven del mal control de patologías como la de Crohn; o por infecciones del colon, por lo general, su causa radica en una colitis inflamatoria, isquémica o infecciosa. El trastorno consiste en el ensanchamiento del intestino grueso originado en pocos días que, aun siendo infrecuente, no deja de ser potencialmente fatal. El objetivo del presente estudio se centra en la aportación de un material bibliográfico actualizado que sirva no solo para el fortalecimiento del conocimiento científico académico en relación al megacolon tóxico, su diagnóstico y tratamiento, sino también, como fundamento de futuras investigaciones. En razón de ello, se ha decidido adelantar un estudio de diseño bibliográfico con el cual recopilar varios criterios de tratadistas y expertos, mediante una metodología de revisión. La evidencia plasmada en los resultados incluye definiciones de megacolon tóxico, mención de sus principales síntomas y causas, y algunos los criterios diagnósticos y terapéuticos. Se concluye que el fundamento que determina el MT esta apoyado en tres aspectos: la historia clínica, los datos de respuesta inflamatoria sistémica y la evidencia imagenológica, principalmente radiográfica, de la dilatación colónica. En cuanto al tratamiento, las principales recomendaciones se centran en el bordaje multidisciplinar y el ingreso a la unidad de cuidados intensivos; mientras que el protocolo terapéutico se enfocará fundamentalmente en el tratamiento de la causa subyacente, la aplicación de medidas generales y, por último, en la cirugía.

Authors: Sulistiyono Edy , Missriani Missriani , Fitriani Yessi
Published: November 2021

This study aims to determine the success of implementing constructivism-based and contextual learning systems in Indonesian language learning, in particular, the five-grade first semester at SD Negeri 44 OKU with on-line learning techniques in the midst of the Covid-19 pandemic. This study uses qualitative research methods. The data collection techniques used were participant observation, structured interviews, and documentation. The results showed several recommendations for distance learning designs by viewing teaching as a process of interaction between learning actors. Interactions that are mediated by this technology need to be carefully designed and implemented based on the needs of students. Apart from what has been shared here, the spaces for innovation are still very wide open in the design and implementation of distance learning, with learning spaces to continuously improve teaching. The vast space for innovation and learning is what frees educators to continue to observe, ask, try, find, and reflect on what forms of distance learning are most appropriate to the context of their students.
