Management of post-COVID antral gastritis associated with hiatal hernia as Urdhwaga-amlapitta through Ayurveda: A case report
Authors: Bhatted Santosh Kumar , Malhotra Nishant 
Published: July 2023

Abstract:
Gastroesophageal Reflux Disease (GERD) is a condition where the gastric contents come back up into the esophagus. Hiatal hernia is a condition, in which the upper part of the stomach or other internal organs bulges through the hiatus of the diaphragm. When there is a laxity in the hiatus, there may be acid reflux, and the symptoms of GERD may arise. In the present case, a 40-year-old female after recovering from COVID-19 in May 2021 started complaining of symptoms such as severe acid reflux, nausea, vomiting, unsatiety/increased appetite, and gradual weight gain. She consulted general physicians/surgeons who diagnosed the condition as mild antral gastritis and hiatus hernia. After getting allopathic treatment for about three months, no significant relief was observed. After that, the patient visited Ayurveda Hospital in November 2021 and was diagnosed as a case of Urdhwaga-amlapitta (~upward hyperacidity). She was treated with Pitta (~Dosha responsible for regulating body temperature and metabolic activities) pacifying medicines (Avipattikara churna, Madhuyashti churna, Shatavari churna, and Kamadudha rasa) for 42 days along with diet and lifestyle modifications. All the symptoms were reduced during the treatment and after follow-up on the 56th day, the patient completely recovered. This case report gives insight that Ayurveda management can be effective for the management of antral gastritis associated with hiatal hernia.

Published: July 2023

ABSTRACT

Aims and Objectives:
The aim of this study is to study the efficacy of simvastatin in bone regeneration following the local application in third molar extraction sockets.

Materials and Methods:
This is a randomized controlled trial done on 50 patients involving 100 third molar teeth extraction sockets. The patients were randomly divided based on the placement of simvastatin. Extraction sockets which were treated with simvastatin were considered study sockets and without simvastatin were considered control sockets. The study socket was assigned for the placement of simvastatin (10 mg) powder along with gelfoam as carrier moistened with normal saline solution and control socket was assigned for the placement of gelfoam moistened with saline. Intraoral periapical radiographs were taken on the 1st, 4th, 8th, and 12th weeks, and mean gray scale values indicating bone density were evaluated for both the groups. Cone-beam computed tomography (CBCT) was taken by the end of the 12th week to further evaluate the osseous regeneration. Patients were compared and evaluated for bone density, pain, and swelling. Pain and swelling were evaluated on postoperative days 1 and 7.

Results:
The mean gray-level histogram values (bone density) were statistically highly significant in the study group compared to the control group in the 1st, 4th, 8th, and 12th weeks, and CBCT also showed statistically significant difference between the control and study group by the end of the 12th week.

Conclusion:
The present data suggest that the local application of simvastatin promotes and enhances bone formation in the extraction sockets, which provides a very cost-effective way for faster bone regeneration.

Authors: Mishra Madan , Singh Gaurav , Gaur Amit , Mondal Shubhamoy , Singh Abhishek , Bharti Pallavi 
Published: July 2023

ABSTRACT

Background:
Anterior segmental Bi-jaw orthognathic surgery is indicated primarily for the correction of dentoalveolar protrusion. They are also indicated for correcting apertognathia, closing interproximal spaces between segments and can be incorporated with other osteotomies to obtain better results.

Aim:
The aim of this study was to analyze and compare the soft- and hard-tissue changes in patients who underwent combined anterior segmental bi-jaw orthognathic surgery.

Settings and Design:
To compare and evaluate soft- and hard-tissue changes before and after combined anterior segmental bi-jaw orthognathic surgery by assessing (a) parameters in vertical dimension and (b) parameters in horizontal dimension and patient satisfaction was also assessed following surgery at 6 months’ time interval.

Materials and Methods:
It is a prospective, single center and analytical study with sample size of 20 patients. It required routine setup for orthognathic surgery and manual tracing of lateral cephalograms. The surgical outcomes were assessed by hard tissue (Sella Nasion Point A (SNA) angle, Sella Nasion Point B (SNB) angle, Point A Nasion Point B (ANB) angle, NAPg, U1-NF, L1-MP angles; NA, NB, B-Pg, Nasion-Anterior nasal spine (N-ANS) distance, Anterior nasal spine-Gnathion (ANS-Gn) distance, and overjet and overbite) and soft tissue (facial convexity, NL, LM angles; LM fold, UL and LL protrusions, Upper lip length (ULL), Lower lip length (LLL), Sn-A, Si-B, Pg-Pg*, Ls-U1, Li-L1 distances, interlabial gap, and U1 exposure) variables pre and postsurgery.

Statistical Analysis:
Descriptive statistics involved the mean and standard deviation, and recorded data were subjected to the statistical analysis using IBM SPSS 20 statistical package. The paired t-test, Pearson correlation coefficient were used. The level of significance P < 0.05 was taken as statistically significant and P < 0.01 as very significant.

Results:
Overall improvement after surgery in both hard- and soft-tissue parameters was observed and significant changes were seen in every variable, except Si-B (P > 0.05). Correlations between soft- and hard-tissue changes were significant in both sagittal and vertical planes. Patients’ satisfaction score showed that all patients had the high overall rate of satisfaction.

Conclusions:
Our study concludes that combined anterior segmental bimaxillary orthognathic surgery is a simple technique with minimal postoperative complications and limited relapse. The changes in facial esthetics and occlusion following orthognathic surgery depend highly on the stability achieved during the postoperative period.
Clinical indications for radical resection of odontogenic keratocyst: A systematic review
Authors: Bushabu Fidele N. , Titinchi Fadi , Bing Liu , Davda Latha 
Published: July 2023

ABSTRACT
The aim of this study was to identify clinico pathological indications for radical resection of odontogenic keratocysts (OKCs) in the literature and formulate clinical guidelines for the management of OKCs based on these findings. A systematic review of the literature was undertaken in September 2021 in PubMed/Medline, Scopus, Web of Science, Google Scholar, and Cochrane databases. The following MeSH Keywords terms were used in the search strategies: (odontogenic keratocyst) OR (keratocystic odontogenic tumor) OR (primordial cyst) AND (treatment) OR (Radical resection) OR (Resection of OKC) OR (Treatment methods). Eligibility criteria included publications of clinical studies on histologically confirmed OKCs which underwent radical resection. Studies with less than 5 OKCs, experimental studies, epidemiological studies, studies that included orthokeratinized odontogenic cyst, and review papers were excluded. Ten studies on OKCs reporting on segmental or marginal resections were identified and analyzed qualitatively. Of the total of 221 OKCs that underwent radical resection, 67 OKCs were primary, 30 were recurrent, and the remaining were unclear whether they were primary or recurrent. Segmental mandibulectomy was performed in 131 OKCs, marginal mandibulectomy in 87 OKCs, and 3 OKCs were treated by partial maxillectomy. The main indications for radical resection were multilocular appearance, large OKCs (> 5 cm), multiple recurrent OKCs with or without cortical perforation, and malignant transformation. In conclusion, radical resection has its place in the management of OKC. It is indicated when there is an aggressive lesion with bony perforation, involvement of the pterygoid musculature or skull base, and malignant transformation. The surgeon should aim to identify these features to manage OKC appropriately and to prevent multiple recurrences. Clinical guidelines for the management of OKCs are proposed.

Web browsers are the applications that the majority of computer users utilize the most. Users carry out a wide range of tasks, including accessing the internet, downloading files, and using social media programs, using a web browser to access email accounts. Many crimes committed using digital resources need to be investigated by looking at online browser history. Such information must be included in the reports of the examiners that will generate one of the data gathered, particularly about crimes involving entering the URL, downloaded files, access times, search phrases browser type, and times. Different methods are used by web browsers to store user data. Additionally, the locations where data is stored vary depending on the operating system being used. The analysis of web browsers on digital resources that are subject to criminal activity, data from various browsers on various operating systems, storage types, and data types that can be retrieved are all demonstrated in this study. Also, we demonstrated the capabilities and tools used in the web browser to review the records.

Published: July 2023

Objective: The objective was to evaluate depressant effects on central nervous system (CNS) and behavioral effects of ethanol extract of clitoria annua and to find the phytochemical responsible for these activities with possible mode of action. Materials & Method: The central nervous system (CNS) depressant activity of C. annua was evaluated by the classical models of depression as Rota rod method, Actophotometer test, tail suspension, and thiopental sodium induced sleeping time tests in Rat. The Rats were divided into Normal, Standard, and two test groups containing five rats each. The test groups received extract at the doses of 200, and 400 mg/kg body weight orally where as the Normal group received distilled water (0.1 ml/mice, p.o.). Diazepam (2 mg/kg, i.p.) was used as standard drug. Results: It is clear that the plant extract significantly decreased the locomotor activity of rats in Rota rod method and Actophotometer test when compared to the normal (p < 0.05). It is observed that the extract showed significantly (p < 0.05) increased in immobility time in tail suspension test in mice. In addition, the extract produced prolongs the sleeping time with onset of action in contrast to the normal group. Conclusions: The present work depicts the evaluation of possible CNS depressant activity of C. annua in mice models. EECA can be a safe and effective approach/alternative for the treatment of number of CNS depressant disorders. More extensive study is required to fractionate, purify, and identify the exact mechanism of action CNS Depressant activity present in ethanolic extract of Clitoria annua with its active ingredients.

Published: July 2023

The effect of H2S on the aqueous corrosion behavior of mild steel was evaluated at high-pressure and high-temperature (HPHT) conditions at a partial pressure of CO2 of 12 MPa and a temperature of 160°C. The corrosion rate of steel samples was determined by electrochemical and weight loss measurements. The surface and cross-sectional morphology and the composition of the corrosion product layers were analyzed by using surface analytical techniques (scanning electron microscopy, energy-dispersive x-ray spectroscopy, and x-ray diffraction). Results showed that the corrosion rate decreased with time and no significant difference was observed in the presence of 1,000 ppm and 2,000 ppm of H2S at HPHT CO2 conditions. Surface and cross-sectional analyses revealed that the corrosion process was governed by the formation of FeCO3 regardless of the presence of H2S. Furthermore, the corrosion behavior of mild steel in these conditions did not depend significantly on flow velocity.
Evaluating precipitation distributions at regional scales: a benchmarking framework and application to CMIP5 and 6 models

Published: July 2023

Abstract. As the resolution of global Earth system models increases, regional-scale evaluations are becoming ever more important. This study presents a
framework for quantifying precipitation distributions at regional scales and applies it to evaluate Coupled Model Intercomparison Project (CMIP) 5 and 6 models. We employ the Intergovernmental Panel on Climate Change (IPCC) sixth assessment report (AR6)
climate reference regions over land and propose refinements to the oceanic regions based on the homogeneity of precipitation distribution
characteristics. The homogeneous regions are identified as heavy-, moderate-, and light-precipitating areas by K-means clustering of Integrated Multi-satellitE Retrievals for Global Precipitation Measurement (GPM) version 6 final run product (IMERG)
precipitation frequency and amount distributions. With the global domain partitioned into 62 regions, including 46 land and 16 ocean regions, we
apply 10 established precipitation distribution metrics. The collection includes metrics focused on the maximum peak, lower 10th percentile, and
upper 90th percentile in precipitation amount and frequency distributions; the similarity between observed and modeled frequency distributions; an
unevenness measure based on cumulative amount; average total intensity on all days with precipitation; and number of precipitating days each
year. We apply our framework to 25 CMIP5 and 41 CMIP6 models, as well as six observation-based products of daily precipitation. Our results indicate that
many CMIP5 and 6 models substantially overestimate the observed light-precipitation amount and frequency, as well as the number of precipitating
days, especially over midlatitude regions outside of some land regions in the Americas and Eurasia. Improvement from CMIP5 to 6 is shown in some
regions, especially in midlatitude regions, but it is not evident globally, and over the tropics most metrics point toward degradation.

Abstract. Coastal floods, driven by extreme sea levels, are one of the most dangerous
natural hazards. The people at highest risk are those living in low-lying
coastal areas exposed to tropical-cyclone-forced storm surges. Here we
apply a novel modelling framework to estimate past and/or present and future storm-surge-level and extreme-sea-level probabilities along the coastlines of southern
China, Vietnam, Cambodia, Thailand, and Malaysia. A regional hydrodynamic
model is configured to simulate 10 000 years of synthetic tropical cyclone
activity, representative of a past/present (1980–2017) and high-emission-scenario future (2015–2050) period. Results show that extreme storm surges, and therefore total water levels, will increase substantially in the coming decades, driven by an increase in the frequency of intense tropical
cyclones. Storm surges along the southern Chinese and northern and southern Vietnamese
coastlines increase by up to 1 m, significantly larger than expected changes in mean sea-level rise over the same period. The length of coastline that is presently exposed to storm surge levels of 2.5 m or greater will more than double by 2050. Sections of Cambodian, Thai, and Malaysian coastlines are projected to experience storm surges (at higher return periods) in the
future, not previously seen, due to a southward shift in tropical cyclone
tracks. Given these findings, coastal flood management and adaptation in
these areas should be reviewed for their resilience against future extreme
sea levels.
Post-Little Ice Age rock wall permafrost evolution in Norway

Published: July 2023

Abstract. The ground thermal regime and permafrost development have an important influence on geomorphological processes in periglacial regions and ultimately
landscape development. About 10 % of unstable rock slopes in Norway are potentially underlain by widespread permafrost. Permafrost thaw and
degradation may play a role in slope destabilisation, and more knowledge about rock wall permafrost in Norway is needed to investigate possible links
between the ground thermal regime, geomorphological activity and natural hazards. We assess spatio-temporal permafrost variations in selected rock
walls in Norway over the last 120 years. Ground temperature is modelled using the two-dimensional ground heat flux model CryoGrid 2D along nine
profiles crossing instrumented rock walls in Norway. The simulation results show the distribution of permafrost is sporadic to continuous along the
modelled profiles. Results suggest that ground temperature at 20 m depth in steep rock faces increased by 0.2 ∘C per decade on average
since the 1980s, and rates of change increase with elevation within a single rock wall section. Heat flow direction is primarily vertical within
mountains in Norway. Nevertheless, narrow ridges may still be sensitive to even small differences in ground surface temperature and may have
horizontal heat fluxes. This study further demonstrates how rock wall temperature increase rates and rock wall permafrost distribution are
influenced by factors such as surface air temperature uncertainties; surface offsets arising from the incoming shortwave solar radiation; snow
conditions on, above and below rock walls; and rock wall geometry and size together with adjacent blockfield-covered plateaus or glaciers.
Reflections: Rethinking Engagement and Student Persistence
Authors: Tinto Vincent 
Published: July 2023

We are delighted to feature this timely reflective article on Rethinking Engagement and Student Persistence by Professor Vincent Tinto, Distinguished University Professor Emeritus at Syracuse University, United States of America (USA). It’s timely because six years ago Professor Tinto reflected in this Journal on Student Persistence – and that was pre-COVID, and the associated mass transition to online, flexible and hybrid learning modalities. We are delighted because during the STARS 2023 Conference, it was apparent that Professor Tinto’s work continues to inspire and guide practice as he generously offers his thoughts to practitioners and researchers who share his passion for improving student outcomes. In this article, Vincent explores the role that social networks have in fostering student engagement, leading to persistence. As he puts it ’engagement matters’ and indeed it does, although its impact as he says remains relatively under-explored. Vincent considers social networks using the classroom and curriculum as contexts for understanding how different forms of networks: tight or loose, dense or sparse can engender different outcomes for students noting that the mere existence of a network will not always lead to positive student engagement. He gives attention to the formation of networks and notes that some of these connecting relationships are less visible, especially for online students and for those students whose networks exist in virtual social spaces that are outside the realm of our institution. Acknowledging that staff cannot and should not seek to be involved in all student networks, he implores us to do what we can to foster productive networks within our spheres of influence, because put simply ‘student engagement cannot be left to chance.’

Authors: Barja Amusquivar Mirian Gabriela , Casso Arias Marcela Geovana 
Published: July 2023

El presente trabajo pretende dar impulso al uso de aulas interactivas con las características tecnológicas con las que deben contar para generar espacios de enseñanza y desarrollo dentro de los talleres de diseño. Al hablar de características tecnológicas se hace referencia a internet de banda ancha, proyectores para tercera dimensión de 360 grados, pizarrones digitales y tabletas o celulares con acceso a plataformas de enseñanza y con posibilidades de conectarse unas con otras mediante dispositivos móviles. Es importante dentro de esta estrategia considerar la práctica docente y el buen manejo de todas estas tecnologías de enseñanza para habilitarlos a planificar y enseñar en entornos interactivos (pero esto corresponde a una segunda fase). El componente principal de esta propuesta se basa en el diseño del aula, que debiera gozar de las instalaciones necesarias para poder contar con los elementos anteriormente mencionados; constructivamente debe constar de muros perfectamente enlucidos, pisos blancos de materiales de primera calidad para la proyección propicia y la dotación de rieles en el cielo falso o losa para el movimiento de los proyectores. Estos y otros detalles más persiguen la intención de lograr espacios propicios para que se dé la interacción dentro del aula.
