Anterior capsular reconstruction with acellular dermal allograft for subscapularis deficiency: a report of two cases
Authors: Mirzayan Raffy , Korber Shane
Published: December 2023

Anterior glenohumeral instability with an irreparable subscapularis tear is a challenging problem for the orthopedic shoulder surgeon. Current techniques, including tendon transfers, yield inconsistent results with high rates of recurrent instability. Acellular dermal allografting has been used in young patients with massive superior rotator cuff tears with early success, but acellular dermal allografting is comparatively unstudied in anterior deficiency. We present two cases of anterior capsular reconstruction with an acellular dermal allograft in patients ages 66 and 58 years with irreparable subscapularis tendon tears. Follow-up for both patients exceeded 4 years, with forward flexion >140°, external rotation exceeding 60°, a Single Assessment Numeric Evaluation score >90 points, a visual analog scale score of 0 points, and an American Shoulder and Elbow Score of 98 points. In conclusion, acellular dermal allografting can be used to reconstruct the anterior capsule in patients with massive irreparable subscapularis tears, similar to its use in superior capsular reconstruction in patients with massive posterosuperior rotator cuff tears.

Published: December 2023

The aim of this systematic review was to collect evidence on the following 10 technical aspects of glenoid baseplate fixation in reverse total shoulder arthroplasty (rTSA): screw insertion angles; screw orientation; screw quantity; screw length; screw type; baseplate tilt; baseplate position; baseplate version and rotation; baseplate design; and anatomical safe zones. Five literature libraries were searched for eligible clinical, cadaver, biomechanical, virtual planning, and finite element analysis studies. Studies including patients >16 years old in which at least one of the ten abovementioned technical aspects was assessed were suitable for analysis. We excluded studies of patients with: glenoid bone loss; bony increased offset-reversed shoulder arthroplasty; rTSA with bone grafts; and augmented baseplates. Quality assessment was performed for each included study. Sixty-two studies were included, of which 41 were experimental studies (13 cadaver, 10 virtual planning, 11 biomechanical, and 7 finite element studies) and 21 were clinical studies (12 retrospective cohorts and 9 case-control studies). Overall, the quality of included studies was moderate or high. The majority of studies agreed upon the use of a divergent screw fixation pattern, fixation with four screws (to reduce micromotions), and inferior positioning in neutral or anteversion. A general consensus was not reached on the other technical aspects. Most surgical aspects of baseplate fixation can be decided without affecting fixation strength. There is not a single strategy that provides the best outcome. Therefore, guidelines should cover multiple surgical options that can achieve adequate baseplate fixation.

Alternative to mesh repair for ventral hernias: Modified rectus muscle repair
Authors: Naraynsingh Vijay , Cawich Shamir O , Hassranah Samara
Published: December 2023

BACKGROUND

Mesh utilization for ventral hernia repair is associated with potential complications such as mesh infections, adhesions, seromas, fistula formation and significant postoperative pain. The modified rectus muscle repair (RMR) is as an option to repair midline ventral hernias without mesh.

AIM

To evaluate the short term outcomes when the modified RMR was used to repair ventral hernias.

METHODS

This was a 5-year prospective study that examined the outcome of all consecutive patients with ventral abdominal wall hernias > 5 cm in maximal diameter who underwent repair using the modified RMR technique in a single surgeon unit. Patients were reviewed in an outpatient clinic at 3, 6 and 12 mo and evaluated for hernia recurrence on clinical examination. Each patient’s abdominal wall was also assessed with using ultrasonography at 24 mo to detect recurrences. All data were examined with SPSS ver 18.0.

RESULTS

Over the 5-year study period, there were 52 patients treated for ventral hernias at this institution. Four patients were excluded and there were 48 in the final study sample, at a mean age of 56 years (range 28-80). The mean maximal diameter of the hernia defect was 7 cm (range 5-12 cm). There were 5 (10.4%) seromas and 1 recurrence (2.1%) at a mean of 36 mo follow-up.

CONCLUSION

The authors recommend the modified RMR as an acceptable alternative to mesh repair of ventral hernias. The seroma rate can be further reduced with routine use of drains. The modified RMR also has the benefit of eliminating all mesh-specific complications.

Finalmente, se estudia la decisión del Consejo de la Judicatura de Ecuador, de crear dependencias judiciales especializadas en delitos de crimen organizado y corrupción, cuyas funciones iniciaron en diciembre de 2022, así como los desafíos de formación continua que tienen las y los nuevos jueces para llevar a cabo el juzgamiento de dichos delitos con la experticia requerida.
Prioridad macroeconómica del gasto público en la administración de justicia en Panamá
Authors: Ríos Vielsa
Published: December 2023

La asignación presupuestaria es el instrumento que permite establecer la distribución más equitativa e intenta asignar los recursos nacionales disponibles mediante planes estratégicos a corto y largo plazo para contribuir al bienestar general. Este trabajo aborda la relación entre el presupuesto y algunas variables de la administración de justicia, así como un acercamiento con el Producto Interno Bruto (PIB) para comprender el impacto del sistema judicial panameño en el crecimiento económico. Para esto, se realiza un diseño de investigación no experimental, ya que no se realizó control sobre las variables objeto de estudio y se observaron los hechos tal como se manifestaron para el período 2012-2022, con un enfoque cuantitativo, descriptivo, correlacional y longitudinal. El objetivo del trabajo consiste en examinar en qué medida la asignación presupuestaria incide en los resultados de la administración de justicia mediante el uso de variables independientes, tales como el Presupuesto Ley designado al Órgano Judicial, el porcentaje del gasto público destinado al Órgano Judicial, el presupuesto del Órgano Judicial por habitante; y como variables dependientes se pueden considerar los indicadores de resultados tales como audiencias realizadas, los casos pendientes al culminar cada período, tiempo promedio de respuesta (en años), la pendencia o casos por resolver al culminar el período, la tasa de congestión, la tasa de descongestión y la tasa de resolución. Al concluir el análisis estadístico, se estableció que, si aumenta el presupuesto asignado al Órgano Judicial, se producen dos efectos: las audiencias realizadas aumentan y, por tanto, existe una relación positiva; y hay una relación inversa con la carga laboral y los casos pendientes, porque estos disminuyen. Por consiguiente, las asignaciones presupuestarias inciden en los resultados de la gestión de justicia, mejorando su eficiencia y productividad, y contribuyendo al incremento del PIB.

Anistia e ruptura: Rememorar, julgar, responsabilizar para não repetir
Authors: Manso de Barros Rita Maria
Published: December 2023

Como a palavra anistia voltou a circular no Brasil, referente aos supostos, e até mesmo prováveis, crimes cometidos por seus inúmeros atores durante os quatro anos do governo de extrema-direita (2018-2022), fugindo da responsabilização pelos efeitos de seus atos e omissões, este artigo discute, a partir do referencial teórico psicanalítico, os mecanismos que levam à reprodução do mesmo e suas consequências íntimas e coletivas quando uma situação traumática não é superada. Expõe o pensamento freudiano sobre o trauma e a necessidade de romper com a compulsão a repetir que ele impulsiona. Toma o pensamento lacaniano sobre tyché e automaton e o destino peculiar que Ferenczi confere ao conceito de negação do fato traumático. Destaca os momentos mais recentes de trauma coletivo vivido no Brasil e o tratamento deliberadamente displicente dado à pandemia e o sufocamento de manifestações artísticas, intelectuais, científicas. Vários países da América do Sul sofreram golpes militares e viveram sob o jugo de ditadores no século XX. Contudo, o Brasil foi o único que não apurou e julgou os crimes perpetrados durante a ditadura (1964-1985), o que causa apreensão que isso se repita após os quatro anos de destruição e terror vividos sob o regime fascista de Bolsonaro e seus asseclas. O artigo propõe a orientação psicanalítica que coloca a necessidade de romper com a reprodução do mesmo para superação de traumas, construção de memória para continuidade da vida.

ICU Nurses’ attitudes and Perceptions towards COVID-19 Patients is crucial because it illuminates challenges regarding caring these patients in the critically ill. This cross-sectional descriptive correlational study employed 85 Saudi ICU nurses worked with critically ill COVID-19 patients since 2020 until present in the government hospitals affiliated in the Ministry of Health (MOH) in Hail Region. These hospitals included King Khalid Hospital, King Salman Specialist Hospital, Hail general Hospital, Maternity and Child Hospital, and Sharaf Hospital, as they all have intensive care units in different specialties. A self-administered questionnaire through online survey was used and composed of three parts, (1) socio-demographic profile of the respondents, (2) the attitudes of the respondents in Caring for COVID-19 Patients and (3) perceptions of the respondents in Caring for COVID-19 Patients. The tool was adopted from Al-Dossary et al. (2020). The majority of nurses participated in the study aged between 25-34 years old, hold bachelor’s degree, and had between 2-5 years clinical experience. Nurses’ perception and attitude were moderately positive. However, male and females were differed in respect to attitude and perception. Likewise, education, age, and length of hospital experience were also influential to the attitudes and perception. In conclusion, healthcare organizations should evaluate ICU nurses attitudes and perception of pandemics to ensure safer and optimal practice.

Bothrops colombiensis es una especie de serpiente venenosa de importancia médica en Venezuela. El envenenamiento por esta especie implica el desarrollo de coagulopatías, miotoxicidad y hemorragias, consecuencia de la presencia en sus venenos de una mezcla de enzimas hidrolíticas como fosfolipasas A2, serino y metaloproteasas. Sin embargo, estudios previos han demostrado una importante variabilidad bioquímica, inter e intraespecie entre los venenos de serpiente, factor asociado a las características ontogenéticas y a la localización geográfica de los ejemplares, siendo necesaria su caracterización. Este estudio evaluó comparativamente los venenos de especímenes de B. colombiensis, colectados en Barlovento, Maracay y Paracotos, mediante el análisis de sus perfiles electroforéticos y sus actividades: procoagulante, hemolítica indirecta y proteolítica sobre fibrinógeno, BAEE (N-benzoil-L-arginina etil éster) y gelatina, además del reconocimiento antigénico por el antiveneno comercial venezolano empleando el método de Ouchterlony. Los resultados evidenciaron una importante variabilidad intraespecie, la cual se relacionó a los constituyentes más relevantes del género Bothrops (proteasas y fosfolipasas A2) y fue más marcada entre los venenos de las regiones más cercanas. El ensayo de Ouchterlony mostró en todos los casos reactividad inmunológica cruzada, aunque con variaciones en los perfiles de reconocimiento. Los datos obtenidos permitirán ampliar la información disponible en la literatura sobre la variabilidad geográfica de los venenos de la especie B. colombiensis, aspecto de relevancia para la comprensión y el manejo de sus envenenamientos e incluso la producción de antivenenos, al contribuir con la selección controlada de los venenos que constituirán los inóculos de producción y venenos de referencia.

La dopamina (DA) está relacionada con los trastornos neurodegenerativos que afectan al sistema nervioso central (SNC) tales como la enfermedad de Parkinson. Con el propósito de contribuir en la búsqueda de nuevos fármacos capaces de restablecer la homeostasis de la transmisión dopaminérgica en la enfermedad de Parkinson, en estudios previos se realizó la síntesis y evaluación farmacológica de los compuestos clorhidratos de N-[(2,4-diclorofenil)-1-metiletil]-2-aminoindano 2, N-[(3,4-diclorofenil)-1-metil-etil]-2-aminoindano 3 y N-[(2,6-diclorofenil)-1-metil-etil]-2-aminoindano 4, los cuales mostraron actividad como agonistas dopaminérgicos centrales al inducir respuestas conductuales estereotipadas propias de los ganglios basales y del sistema límbico. El compuesto 4 presentó mayor selectividad hacia las respuestas de los ganglios basales que las límbicas. En el presente trabajo se realizó el estudio conformacional y electrónico de los compuestos 2-4, a través del programa GAUSSIAN-09 (G-09) y la Teoría del Funcional de la Densidad (DFT), empleando el funcional híbrido de rango separado ωB97XD con el conjunto base 6-31+G**. El compuesto 4 presentó una significativa disminución del momento dipolar, lo que explicaría su afinidad hacia los ganglios basales, y dejando entredicho que son más hidrofóbicos que las estructuras límbicas. Este estudio permite incluir al compuesto 4 como potencial agente capaz de contrarrestar la enfermedad de Parkinson.

Fully understanding factors that are related to teachers’ behavioural intentions to use and acceptance of Educational Robotics (ER) in their classes, particularly among students with disabilities, is a big challenge. In particular, social psychology models may be used more consistently to inform scholars about the paths and the strength of interrelated factors influencing learning support teachers’ acceptance of ER. In this study, the Almere model, an evolution and adaptation of the Unified Theory of Acceptance and Use of Technology (UTAUT) as used in Conti and colleagues was validated. The model is directed to measure acceptance of ER in a sample of 319 learning support teachers via structural equation modeling. Results showed a model explaining a good percentage of variance. In the learning support teachers’ intentions to use ER with students with disabilities, positive and direct effects were exerted by teachers’ positive attitudes toward robotics, and by their perception of the enjoyment and usefulness of robotics. Furthermore, results showed that perception of enjoyment in using ER was strongly and positively associated with perceived sociability and this, in turn, was positively associated with levels of trust. Finally, perceived sociability was positively associated with social presence perceptions.

Глобальный переход к экологически чистой энергии продвигается очень быстро. По мере роста спроса на экологически чистые технологии, такие как электромобиль, солнечные батареи, ветровая энергия, и кабели передачи растет и потребность в меди, которая проводит электричество, обеспечивая переход источников энергии на альтернативные и возобновляемые. Переход на технологии альтернативной энергетики есть драйвер для роста меди в долгосрочной перспективе. Этот рост связан с переходом на экологически чистые виды транспорта, солнечные и ветровые станции. В процессе этого перехода резко возрастет потребление меди. Медь используется в 2/3 технологических решений для сокращения выбросов парниковых газов. По прогнозам, к 2050 году объем потребления меди в мире может увеличиться вдвое. В работе представлены данные по производству меди и изменению ее стоимости, приведены диаграммы спроса на медь по отраслям и изменение стоимости меди за последние годы. Исторический металл становится инновационной точкой движения для перехода на новый технологический уклад. За последнее время медь увеличила свой спрос в разы, особенно в промышленном секторе. Например, больницы меняют многие поверхности на медь, к которым можно прикасаться, поскольку вирусы и бактерии не могут жить на металле. В данной работе анализируются риски и способы инвестирования в медь, изучены возможности и положительные стороны применения инвестиций в медь.

The global transition to clean energy is moving very quickly. As demand for clean technologies such as electric vehicles, solar panels, wind power and transmission cables grows, so does the need for copper, which conducts electricity, enabling the transition of energy sources to alternative and renewable ones. the transition to alternative energy technologies is a driver for copper growth in the long term. this growth is associated with the transition to environmentally friendly modes of transport, solar and wind power plants. During this transition, copper consumption will increase sharply. Copper is used in 2/3 of technological solutions to reduce greenhouse gas emissions. According to forecasts, by 2050, global copper consumption could double. the work presents data on copper production and changes in its value, provides diagrams of demand for copper by industry and changes in the cost of copper in recent years. Historical metal becomes an innovative point of movement for the transition to a new technological structure. Recently, copper has increased its demand significantly, especially in the industrial sector. For example, hospitals are replacing many touchable surfaces with copper because viruses and bacteria cannot live on the metal. this paper analyzes the risks and methods of investing in copper, and examines the possibilities and positive aspects of investing in copper.

Авторы в статье постарались системно изложить сущность и содержание инвестиционных мероприятий в предприятия российского машиностроения, показали их значимость для экономической безопасности страны. Представлены факторы, действующие на инвестиционную политику правительства страны. Приведены подходы к формированию «длинных» инвестиций в производство по сравнению с «короткими» инвестициями в торговлю и банковский сектор. Высказано предположение о наличии инвестиционных и кредитных ресурсов в российском экономическом поле в виде временно свободных денежных средств для кредитования юридических и физических лиц, несмотря на отток средств физических лиц из банков в 2022 и 2023 гг. из-за ожиданий неустойчивости в экономике. Сделан вывод о том, что инвестиции в машиностроительную отрасль тормозятся денежно-кредитной политикой, проводимой банковским сектором экономики, что затрудняет развитие этой отрасли в условиях действующих регламентов банковского, налогового и внебюджетного институтов. Показана необходимость снижения ключевой ставки Центробанка России для роста и развития предприятий машиностроения. Сделан вывод о главном инвестиционном ресурсе для машиностроения - государственных средствах, а также - о необходимости налогового, оффшорного, кредитного стимулирования этих предприятий со стороны государства.

Approaches to the formation of “long” investments in production compared with “short” investments in trade and the banking sector are presented. It is suggested that there are investment and credit resources in the Russian economic field in the form of temporarily free funds for lending to legal entities and individuals, despite the outflow of funds from banks in 2022 and 2023 due to expectations of instability in the economy. It is concluded that investments in the machine-building industry are hindered by the monetary policy pursued by the banking sector of the economy, which complicates the development of this industry in the conditions of the current regulations of banking, tax and extra-budgetary institutions. the necessity of reducing the key rate of the Central Bank of Russia for the growth and development of machine-building enterprises is shown. the conclusion is made about the main investment resource for mechanical engineering - public funds, as well as about the need for tax, offshore, credit incentives for these enterprises from the state.

Background and objectives: Acute pancreatitis is a major cause of hospitalizations in the United States. Imaging is often unwarranted in early, uncomplicated pancreatitis however can prove to be useful in specific clinical scenarios. This study aimed to investigate whether our institution overutilizes abdominal imaging in diagnosis of pancreatitis. Methods: Patients with acute pancreatitis admitted to our institution between 2015 and 2020 were identified using the International Classification of Diseases diagnosis codes. A total of 669 patients met the criteria for acute pancreatitis according to the revised Atlanta Classification. The data was presented using frequencies and percentages and patients with abdominal imaging were compared to those without. Mann Whitney U test and chi-square test were used to compare continuous and categorical variables respectively. Univariable and multivariable regression analysis was used to analyze factors associated with the performance of abdominal imaging. Results: Our results found that 495 patients (74%) had an abdominal computerized tomography (CT) scan, while 363 patients (52%) had an abdominal ultrasound. More than half of the patients who already met 2 out of 3 clinical and laboratory criteria of the revised Atlanta classification still underwent abdominal imaging, even though it was not necessary. However, we found no significant difference in outcomes between patients who underwent imaging and those who did not, including the need for mechanical ventilation, intensive care unit admission, and inpatient death. Conclusion: A significant number of patients admitted for acute pancreatitis undergo abdominal imaging even after fulfilling clinical and laboratory diagnostic criteria.

Published: December 2023

The exploration of Biochemistry research has been expanded by artificial intelligence (AI) and its ability to analyse immense and intricate datasets in a way that would be unattainable by human effort alone. This review delves into the most recent examples of AI breakthroughs that had a transformative impact on key aspects of biochemistry. AI has now led to the creation and improvement of drug molecules and the capability to predict which new proteins could be targeted for repurposing with current drugs. When it comes to protein structures, algorithms such as AlphaFold have made great strides in resolving the protein folding problem that has been a challenge for so long. Reliably identifying proteins and metabolites from spectral data is now possible with deep learning models. Meanwhile, AI can classify sequences and spot gene expression patterns in massive genomics and transcriptomics datasets with ease. The remarkable capabilities of AI to automate the analysis of medical images and natural language descriptions of patient symptoms have a promising potential for transforming disease diagnosis and treatment. Nevertheless, obstacles such as data availability, interpretability of AI models, ethical considerations, and generalization must be tackled as these technologies evolve. The collaboration between AI and biochemistry appears to be optimistic, with biochemical data powering the development of more robust AI systems that can extract new knowledge from vast datasets beyond human reach. Thus, this mutually beneficial relationship has the potential to vastly expedite discovery across molecular biology.

Published: December 2023

Concrete is one of the most widely used construction material in the world. Increase in population growth is leading to increase in various demands like cultivation, transportation, construction etc. Nowadays, there is a tremendous increase in the demand for construction works like residential buildings, bridges, dams, roads etc. and because of this increase in demand the availability of sources for concrete ingredients is getting difficult. Hence people are looking for alternative sources for the concrete ingredients in order to full fill their requirements. This dissertation work deals with the study of strength of concrete incorporating Recycled Aggregate concrete(R.A.C).The main objective of this investigation is to find out up to what percentage the Natural Coarse Aggregate(N.C.A) can be replaced by recycled coarse aggregate(R.C.A) in the concrete mix and to find out the extra quantity of cement to be added for each percentage replacement byR.C.A. to achieve its target mean strength. In this ongoing project work it is concentrated only on the use of R.C.A. A series of tests were carried out to determine the compressive strength, split tensile strength, flexural strength with and without recycled aggregates. Natural coarse aggregates in concrete were replaced with 0%, 20%, 40%, 60%, 80% and 100% of crushed concrete coarse aggregates. For the strength characteristics, the result showed a gradual decrease in compressive strength, split tensile strength, flexural strength and modulus of elasticity as the percentage of recycled aggregate is increased. Key Words: Natural Coarse Aggregate, Recycled coarse aggregate, compressive strength, split tensile strength, flexural strength.
