Authors: Morshed Mohammed Mamun
Published: August 2023

Background: In a location apart from the regular intensive care unit (ICU), the postanaesthetic care unit (PACU) provides postoperative high-dependency or intense care for high-risk surgical patients. Therefore, it meets the population's well-documented need for better postoperative care. Objectives: The aim of the study was to Assess the risk variables in the post-anesthesia care unit of a tertiary care hospital in Dhaka. Methods: This cross-sectional descriptive study was carried out in the Department of anesthesiology, Uttara Adhunik Medical College Hospital, during October 2020 to September 2021. A total of 100 patients were participate in this study. Patients underwent tonsillectomy, hysterectomy, caesarean section, and laparoscopic cholecystectomy, both male and female were included in this study. Patients who have not given consent to participate in the study were excluded from the study. Statistical Packages for Social Sciences (SPSS-26), where required. Results: About 40% patients were male and 60% were female. 80% of the patients were under ASA classification-1, 15% under ASA classification-2 and 5% were under ASA classification ≥3. Here, 22.22% patients had pre-exixting co-morbidity of respiratory, CVS neurological disease respectively. 30% had DM. Only 3.33% and more than 1 pre-exixting co-morbidity. 94.20% patients had no risk of surgery and only 5.80% patients were under risk of surgery. About 40% patients stayed 60-120 minutes in the post anesthesia care unit, 30% patients stayed 120-180 minutes in the post anesthesia care unit, 20% patients stayed 180-240 minutes in the post anesthesia care unit and 10% patients stayed ≥240 minutes in the post anesthesia care unit. 5% patients had develop complication in the post anesthesia care unit for 1-2 hours, 32% for 2-3 hours, 20% for 3-4 hours and 25% for more than 4 hours.

Published: August 2023

Background: There are recent advances in the management of COVID19 infection, but there is still a need to develop methods of predicting the course of the illness which are reliable yet easy to perform. Determining the rate and timing of detection of total SARSCoV2 anti-nucleocapsid antibodies may help to predict the course of illness in COVID19. Methodology: Patients with COVID19 infection admitted at Ramaiah medical college hospital were categorized based on clinical severity into asymptomatic, mild-moderate and severe/critical illness. Their blood samples were collected at three different time intervals with respect to onset of clinical symptoms to test for the presence of total Anti SARSCoV2 N antigen antibodies (IgG and IgM) and the rate of seroconversion. Results: The findings of this prospective study on the antibody response to COVID19 infection failed to demonstrate a significant difference with respect to anti-nucleocapsid antibody titers among those with mild and severe categories of infection. However based on the results of the present study, it appears that the virus is able to suppress the generation of antibodies and in the process, escape the clutches of the host immune system. Conclusion: The progression or recovery from COVID19 disease can be possibly determined by the rate of seroconversion of total COVID19 anti-nucleocapsid antibodies.

Introduction: The management of children with invasive ventilation in developing countries with limited resources is challenging. A large number of infants in intensive care unit require mechanical ventilation due to various conditions and have a high mortality. Aim of the study: To identify the predictors of mortality among ventilated young infant up to 2 months age in Intensive Care Unit of Bangladesh Shishu Hospital & Institute. Methodology: The prospective observational study was conducted in the Department of Intensive Care Unit of Bangladesh Shishu Hospital & Institute, from January 2020 to December 2020. Critically ill young infants upto 2 months age who required mechanical ventilation in Intensive Care Unit were included in this study. Data was collected on a structured proforma and included the basic demographic profile, presenting complaints, preliminary diagnosis, investigation results, mode of ventilation and initial ventilator parameters & hospital stay and outcome. Permission from ethical review committee of the hospital was taken. Results: From 50 critically ill patients, mortality rate was 74.0%. Mean age was 14±10.1 days. Significant relation was found between the ventilated patients having FiO2, PIP, PEEP, HCO3, BE, serum sodium level, duration of ventilation and outcome respectively. Severe respiratory distress before death was found significantly related with outcome. Metabolic acidosis was found significant in death patients before ventilation and before death (75.7% & 51.4%). Conclusion: The rate of mortality in the ICU was high. Initial high PIP, low HCO3, severe respiratory distress and prolong duration of ventilation (>5days) were significant independent predictors of mortality.
Fault Detection Method based on Local and Global Attention Mechanisms
Authors: Jie LU Zhen
Published: August 2023

In recent years, due to the wide application of Distributed control system, a large number of production process data can be collected and stored, which provides a solid data foundation for process monitoring technology based on deep learning. The Transformer model is a fully connected attention mechanism model that captures the global dependencies of data by calculating the correlation between any two items. This paper proposes a Transformer model based on local and global attention mechanisms. Firstly, after the data is standardized to eliminate the impact of different dimensions, positional encoding is used to mark the position information. Then, the data is divided into two equal parts from the feature dimension. One part enters the standard attention mechanism to capture the global information of the sequence, and the other part enters the local attention mechanism to capture the local information of the sequence, Then, the captured local information and global information are fused to reduce computational complexity and compensate for the shortcomings of the Transformer model in capturing local information. By applying the model proposed in this paper to the penicillin fermentation process for fault detection, it has been experimentally verified that the proposed model has an improved fault detection accuracy compared to the standard Transformer model.
Dropout & Prevention in Fitness Sports
Authors: Tokarski Walter , Tosounidis Antonis , Zarotis George F.
Published: August 2023

High drop-out rates in sports programmes, both health and therapeutic sports, are not exceptional. Long-term retention of active athletes is a problem. This is equally true for fitness training in fitness clubs, where about half of the active individuals drop out prematurely. The aim of this study is to create a comprehensive inventory of the dropout problem and the prevention of it in fitness sports. From the results obtained, recommendations for action can be derived to increase customer satisfaction in fitness facilities and thus reduce the dropout rate in the long term. Methodologically, a review of the relevant literature was conducted in this study. When analysing various research results, it was found that dropping out of a sports programme always depends on several factors. Characteristics of dropping out of sports activity can be personal as well as situational and structural. While it is often possible to identify individual reasons that ultimately tip the balance in favour of quitting, this is usually influenced by a complex set of factors. The reason that fitness club membership fees are too expensive is found at the top of the list in all known studies, followed by the statement that the time spent on sport is too much. Relocation, job and family reasons, other hobbies and, last but not least, health reasons are then usually found in the further course of the lists of dropout reasons. All these reasons seem plausible, but they may also be feigned. They are often difficult to verify by those responsible in the fitness clubs and usually have to be accepted as such. They are rather unsuitable for use in successful dropout prevention. At most, stated health reasons can play a role for preventive measures, but not if serious diseases are involved. Essential demands on the management of a fitness club are therefore the creation of a good social atmosphere during training, time-efficient training programs, fun during the training, fulfilment of training goals and intensive support mechanisms. Only sensible innovations, market-oriented behaviour and flexibility can lead to future success in the fast-moving fitness market.

Published: August 2023

Triage is the first process of assessment and prioritization of all patients who present to emergency departments (EDs) into categories according to their condition and level of urgency. In this study, a systematic review of the literature on the effectiveness of triage systems was conducted in Saudi Arabia. Following PRISMA guidelines, six large databases were searched for relevant articles published between 2003 and 2023. Three authors reviewed the titles, abstracts, and full texts. The databases were searched using the following keywords: triage systems, CTAS, emergency department overcrowding, non-urgent or inappropriate visits to the ED, ED overutilization, and triage and ED overcrowding in the Middle East. A total of 1,051 articles were identified, of which 245 met our inclusion criteria. From the findings of these studies, in relation to the factors that reduce triage efficacy in the Middle East and specifically in Saudi Arabia, it can be argued that there is a need for more studies and solutions to address these issues. Patients are in need of health education, and alternative solutions must be considered to address the high percentage of non-urgent visits to the ED. Emergency department triage is the first screening step that sorts patients in emergency situations by categorizing their urgency levels to prioritize patients for evaluation and treatment. Because the ED is an integral hospital department and a complicated, fast-paced environment, ED healthcare services have evolved to be delivered through effective triage systems to reduce waiting times and overcrowding.

TRATAMENTO NÃO CIRÚRGICO DA PERI IMPLANTITE: UMA REVISÃO DE LITERATURA
Authors: Botelho Bruna Andraus , Lobo Leandro Cecim , Campos Bernardo Oliveira de , De Moura Guilherme Bianchine
Published: August 2023

A doença peri-implantar é uma condição inflamatória que afeta os tecidos ao redor de um implante dentário. As condições peri implantares são divididas em mucosite peri implantar e peri implantite. Mucosite peri-implantar é uma inflamação dos tecidos moles ao redor dos implantes dentários. Já a peri implantite é uma forma de periodontite que afeta os tecidos de suporte ao redor de implantes dentários, resultando em perda óssea ao redor do implante. É causada pela presença de bactérias nocivas que se acumulam na superfície do implante, resultando em inflamação e perda óssea ao redor do implante. O objetivo deste estudo foi realizar uma revisão de literatura sobre o tratamento não cirúrgico da peri implantite que geralmente envolve a remoção das bactérias acumuladas e a descontaminação da superfície do implante. O tratamento não cirúrgico é feito através de procedimentos como raspagem com dispositivos ultrassônicos e abrasivos a ar, terapia com laser, aplicação de agentes antimicrobianos locais, utilização de antibióticos sistêmicos e probióticos. Como conclusão, o tratamento não cirúrgico da peri implantite pode não ser suficiente para casos avançados da doença, sendo necessária a intervenção cirúrgica para restaurar a saúde do implante e evitar a perda do implante.

Published: August 2023

El estudio tuvo como objetivo registrar las barreras socioculturales de la regulación emocional en adolescentes andinos postulantes a un instituto superior pedagógico de Áncash. La investigación de diseño mixto transformativo secuencial se desarrolló en la zona andina de la región Áncash (Perú). La unidad de estudio fueron adolescentes varones (N = 24), entre 16 y 18 años, postulantes de un instituto pedagógico particular, que interactúan en un contexto de internado homosocial. Se diseñó un programa de regulación de emociones que constó de 12 sesiones de 90 minutos. El instrumento de recolección de datos cuantitativos (pre y post test) fue la Escala de Dificultades de Regulación Emocional (DERS) de Gratz y Roemer (2004), adaptada por Huamaní y Saravia (2017) para la población arequipeña, validada por criterio de jueces para la población andina de la región Áncash. Para los datos cualitativos, se aplicaron dos entrevistas semiestructuradas individuales, y registros de la observación de la dinámica de los participantes en cada una de las sesiones del programa. Se evidenció una mejora de la conciencia emocional. No hubo cambios en el rechazo emocional, estrategias y metas, debido a barreras socioculturales producto de una socialización basada en el modelo de masculinidad tradicional vigente en la región andina Fuller (2001). Se recomienda que los programas de educación emocional para varones deben considerar las variables socioculturales y de género.

Conway and Lagarias showed that certain roughly triangular regions in the hexagonal grid cannot be tiled by shapes Thurston later dubbed tribones. Here we introduce a two-parameter family of roughly hexagonal regions in the hexagonal grid and show that a tiling by tribones exists if and only if the two parameters associated with the region are the paired pentagonal numbers $k(3k \pm 1)/2$.
Distribution of External Branch Lengths in Yule Histories
Authors: Disanto Filippo , Fuchs Michael
Published: August 2023

The Yule branching process is a classical model for the random generation of gene tree topologies in population genetics. It generates binary ranked trees -also called histories- with a finite number $n$ of leaves. We study the lengths $\ell_1 > \ell_2 > \cdots > \ell_k > \cdots$ of the external branches of a Yule generated random history of size $n$, where the length of an external branch is defined as the rank of its parent node. When $n \rightarrow \infty$, we show that the random variable $\ell_k$, once rescaled as $\frac{n-\ell_k}{\sqrt{n/2}}$, follows a $\chi$-distribution with $2k$ degrees of freedom, with mean $\mathbb E(\ell_k) \sim n$ and variance $\mathbb V(\ell_k) \sim n \big(k-\frac{\pi k^2}{16^k} \binom{2k}{k}^2\big)$. Our results contribute to the study of the combinatorial features of Yule generated gene trees, in which external branches are associated with singleton mutations affecting individual gene copies.

Transformation of Styrene Oxide on Bi-Functional Ni, Co and Cu Catalysts Supported on Zirconia-Alumina: Effect of Depositing Zirconia on Alumina
Authors: Pathan Ruhi H. , K. Modi Chetan , Basrur Arun G.
Published: August 2023

2-phenyl ethanol (2-PEA) and 2-phenylacetaldehyde (PAA) are important perfumery chemicals which are prepared by hydrogenation and isomerization of styrene oxide (SO) respectively. Activities of Ni, Co and Cu supported on a set of zirconia-alumina supports with varying ZrO2:Al2O3 molar ratio are compared for these reactions. Zirconia was deposited on γ-alumina by deposition-precipitation. All catalysts were characterized by XRD, NH3-TPD, H2-TPR, N2 physisorption, XPS and Raman spectroscopy. Increasing the zirconia content significantly influenced catalyst characteristics. These are correlated with reactivity: i) surface concentration of Ni, Co and Cu (XPS) decreased, which affected conversion of styrene oxide and selectivity to 2-PEA ii) 1 1 1 plane of Cu (XRD) was suppressed which enhanced selectivity of styrene by-product relative to 2-PEA iii) acidity (NH3-TPD) decreased, which adversely affected yield of PAA. Product space time yields (STY) of 2-PEA and PAA correlated well with surface concentration of active metals (XPS) and acidity (NH3-TPD) respectively. Various by-products were identified. Styrene appeared to form by deoxygenation of SO. TPR and Raman spectroscopy indicated strong interaction of Co and Ni with alumina while Cu showed strong interaction with zirconia. This reflected in their XRD crystallite size. Cu has different electronic properties than Co and Ni, which reflected in differences in their behavior. This study directly compares the performance of these transition metals in continuous flow studies and correlates catalyst characteristics with reactivity.

Bei der Bestimmung der Konzentration von chemischen Arbeitsstoffen in der Luft am Arbeitsplatz existieren grundlegende Anforderungen an die Leistungsfähigkeit von Messverfahren und somit auch an ihre Messunsicherheit. Um die Qualität und Eignung eines solchen Messverfahrens beurteilen zu können, ist es notwendig, die Messunsicherheit der eingesetzten Messverfahren zu ermitteln. Um die Messunsicherheit überhaupt berechnen zu können, müssen zunächst relevante Einflussfaktoren auf den Messwert zusammengetragen werden. Die Einflussfaktoren umfassen verschiedene Schritte der Verfahrensvalidierung, vor allem die Probenahme und die Analytik. Im nächsten Schritt müssen zu den Abweichungen jedes relevanten Schritts der Probenaufarbeitung und Validierung Unsicherheiten berechnet werden, um letztendlich die kombinierte Standardabweichung bestimmen zu können. Im zweiten Teil dieses Artikels werden die relevanten Einflussfaktoren beschrieben, eine Einteilung der zugehörigen Abweichungen in systematische und zufällige Effekte vorgenommen und Unsicherheiten berechnet. Diese Schritte werden als Vorbereitung zum Erstellen eines verfahrensspezifischen mathematischen Modells zur Berechnung der Messunsicherheit benötigt, das im folgenden dritten Teil des Artikels anhand eines Beispiels erläutert wird.

Läkare och läkande
Authors: Bergqvist Johanna
Published: August 2023

I samband med sjukdom och ohälsa blir människans litenhet och sårbarhet, men också hennes livsvilja och vilja att förbättra, tydlig. Läkekonst är ett uttryck för människans försök att bemöta och betvinga det oacceptabla som livet ställer henne inför i form av fysiskt och mentalt lidande. Det är också en kulturprodukt. Hur man inom ett samhälle eller en kultur hanterar umbäranden i form av sjukdomar och skador säger därför mycket om ett samhälle i stort; om dagens, såväl som om medeltidens och renässansens. Genom att studera medeltidens och renässansens läkekonst kommer vi en liten bit närmare de människor som levde då.
Med hjälp av arkeologiska fynd och skriftliga källor från det medeltida och renässanstida Sverige och Norden undersöker Johanna Bergqvist hur man under dessa perioder förstod sjukdomar och skador, vad man tänkte sig orsakade dem, hur man behandlade och vårdade dem som drabbats och vilka som arbetade med detta. Under medeltiden och renässansen skedde flera förändringar inom såväl läkekonsten som inom berörda yrken, men utvecklingen gick inte ständigt framåt. Från mitten av 1300-talet och genom 1400-talet innebar Digerdöden och efterföljande epidemier bokstavligen ett dråpslag för äldre kunskaper, traderade genom generationer, som det tog tid att återhämta sig ifrån.

Published: August 2023

Artificial Intelligence (AI) has made significant progress in drug discovery and drug delivery and has become an active area of research. The use of AI in drug delivery has gained significant attention, with the development of new technologies and algorithms that enable more efficient drug delivery. The history of AI in drug discovery can be traced back to the 1960s, and since then, AI has been used in various stages of drug discovery, including target identification, lead optimization, and drug design. AI can aid in different stages of drug development, including drug discovery, formulation, and optimization. AlphaFold is an AI-powered deep learning system that uses neural networks to predict the structure of proteins to design drug molecules. The ultimate goal of using AI in pharmaceuticals is to minimize cost and time and achieve exceptional results without the need for laboratory presence. However, experimental validation is still necessary to verify the accuracy and reliability of the AI-generated results.

Background: Ankle sprain is the most frequent sports trauma. After repeated sprains, Chronic Instability (CAI) occurs and usually requires a surgical procedure. New surgical strategies to treat symptomatic CAI are evolving. In this article we describe a fully arthroscopic technique for CAI treatment. Methods: January 2017 to January 2020, we arthroscopically treated 26 patients for CAI, 21 of these were included in the study. The patient’s average age was 33, 43 years. Median Follow-Up (FU) was 22, 38 months. Using a suture passer or a grasper and knotless anchors, the ligaments were repaired with an arthroscopic technique and reinforced with arthroscopic plication technique. Results: At FU the AOFAS mean was 96, 29; FADI mean was 131, 38; VAS mean was 1, 00. All patients reported subjective improvement in their ankle instability after the arthroscopic repair. Conclusion: Chronic ankle instability can be successfully treated by an arthroscopic repair reinforced with arthroscopic plication technique. It is possible obtain significant functional outcomes with high patient satisfaction.

Published: August 2023

Background: Rotavirus is a type of virus that lacks the membranous layer (envelope); belonging to the family Reoviridae. Rotavirus derived its name from its characteristic appearance of a wheel like structure, as revealed by electron microscopy. This virus has been known for many years as the causative agent of inflamed stomach and intestines among children, which can spread by fecal-oral transmission and clearly exhibit itself with abdominal pains, increased urge to vomit, headache, feeling of discomfort, fever  and severe diarrhea. Therefore, treatment of the infection is primarily targeted. There are two vaccines; Rotarix and RotaTeq, have been developed to stop the viral infection. The administration of Lactobacillus spp. is an additional treatment regime, to reduce the time of the severe stooling.

Objectives: To review and compare the public health consequences of rotavirus gastroenteritis around various communities.

Methodology: Detailed analysis of existing literature on rotavirus gastroenteritis together information on its structure, symptoms, pathology and treatment have been generated. All the relevant articles published from 1962 to 2020 were looked over numerous sources like Google Scholar, Medline, PubMed, Research Gate, Science Direct, Scopus and Web of Science.

Results: After due review, it was observed that rotavirus associated gastritis is most prevalent amongst infants and young children who come in contact with reservoirs and contaminants. The replacement of fluids and electrolytes remain the mainstay for its treatment. Vaccination, along with improved personal hygiene both for the infected and their care givers are the most important methods of preventing the transmission of rotavirus infections. It was also seen that some parts of Africa contributes the highest occurrence rates of rotavirus infections and that infant mortalities recorded annually that are associated with diarrhea are mostly caused by rotavirus.

Conclusion: Rotavirus is the most isolated agent associated with inflamed stomach and intestine (gastroenteritis) in infants and young children with high fatality rate, and it is very contagious. Frequent washing of hands must be encouraged especially in schools, day care facilities, hospitals and other public places to reduce its spread.

Background: Mango is known as the king of fruits. It has several varieties however, some are more popular in the country including Sindhri. Each variety has its significance when used in different food products. The pulp of mango is used for developing jams, beverages, chutney (dips) etc., and sometimes preserved with some additives to be used for the production of mango leather. In general, the application of drying techniques to fruit puree yields a stable shelf-life product called fruit leather, which is of soft rubbery texture with a sweet taste and especially dehydrated.

Objectives: To analyze the effect of various drying techniques (i.e. sun drying, oven drying, and dehydration) on the organoleptic quality (i.e. quality that affects how a consumer experiences the food via their senses e.g. look, taste, smell, and touch) of mango leather.

Methodology: A drying experiment was performed like sun drying, hot air oven drying, and commercial dehydrator to determine the effect of drying times on the quality of mango leathers using these techniques. The effect of the storage period was also studied for the quality of mango leathers. The dried mango leathers were sensory analyzed by the trained panelists.

Results: A minimum drying time of 8-10hours was achieved in a commercial dehydrator for mango fruit leather at 70°C. It was also observed that despite the longer dehydration time, the mango leathers produced remained equally acceptable compared to other dehydration techniques. The mango leathers dried in dehydrater at 70°C ± 2°C gave the highest score of color (6.20), texture (6.13), flavour/taste (5.88), appearance (5.88), and overall acceptability (5.85), while mango leather dried in an oven at 70°C ± 2°C has recorded a score of color (5.93), texture (5.87), flavour/taste (5.77), appearance (5.53), and overall acceptability (5.70). The storage of mango leathers had also a significant effect (p < 0.05) in the storage period of mango leathers as compared to control. A non-significant difference was also observed in all the organoleptic parameters after 10-12 weeks of storage.

Conclusion: It is obtained from the current study that for the production of mango leather, the commercial dehydrator based drying techniques results in acceptable sensory characteristics as well as longer storage period by comparing other drying techniques, as it has a controlled environment.
