The Geo-mapping for Energy and Minerals (GEM) program was funded between 2008 and 2020 with the aim of advancing geological knowledge of the North to reduce risk for mineral exploration and inform land-use decisions and future management of the North. Twenty-one
regional activities were undertaken across Canada's northern shield, spanning northern Prairie Provinces, northern Quebec, Labrador, along with much of Nunavut and Northwest Territories. A further five activities were thematic in nature. Bulletin 612 presents results from 12 of these endeavours,
including integrated regional bedrock geoscience studies, geophysical surveys, and basin analyses, as well as thematic thermochronology, geochemistry and large igneous province syntheses. The results highlight that GEM has contributed to new era of understanding of the northern Canadian Shield,
expanding its framework substantially and developing an increasingly complex model of Archean cratons, Archean/Proterozoic microcontinents, and juvenile Paleoproterozoic crust that highlights the existence of a dozen new pericratonic to exotic ribbon microcontinents within a mosaic once considered
as mostly large cratonic masses welded by Paleoproterozoic orogens. This emerging picture brings additional questions for future northern studies - particularly in the granularity of subdivision of the largest blocks, the impact of enigmatic earliest Paleoproterozoic orogens, and dynamics of
assembly of exotic and little-known terranes.

This short contribution describes the Archean and Proterozoic history of the central Rae Craton in the Tehery Lake-Wager Bay area, Nunavut. The study area comprises six lithotectonic domains separated by large-scale structures: the Gordon Domain, Lunan Domain,
Daly Bay complex, Douglas Harbour Domain, Kummel Lake Domain, and Ukkusiksalik Domain. These domains can be differentiated on the basis of metamorphic assemblages, Nd model and U-Pb ages, absence or presence of specific lithologies, and/or geophysical characteristics. Links between these domains and
neighbouring areas of the central Rae Craton, the timing of assembly of domains and terranes, and the effects of the Snowbird and Trans-Hudson orogenies are briefly described.

Published: March 2024

The geophysical data sets available for the western Churchill Province have had a bearing on the understanding of its structure, evolution, and metal endowment. New data were acquired and interpreted during the Geo-mapping for Energy and Minerals (GEM) program
(2008-2020). Regional, high-resolution aeromagnetic, and targeted gravity and magnetotelluric surveys were collected in GEM, in conjunction with geological mapping projects, in order to provide control on bedrock features beneath widespread glacial overburden and flat-lying sedimentary basins.
Quantitative estimates of three-dimensional geometry were obtained in key areas through geophysical models, integrating the geophysical characteristics with local rock-property measurements. These geophysical data sets contributed to new knowledge and interpretations in three related research
fields: location and nature of Rae Craton's boundaries within the western Churchill Province; definition of internal Rae architecture; and identification of reactivated structures controlling gold and uranium mineralization. The new data, models, and emerging tectonic and metallogenic frameworks
will serve as guides for future exploration in this remote, complex, challenging region.
Summary of GEM results: Manitoba Far North Geomapping Initiative
Authors: Böhm C , Rayner N
Published: March 2024

The far north of Manitoba is endowed with potential for base and precious metals, diamonds, uranium, and rare metals. The goal of a collaborative project between the Manitoba Geological Survey and the Geological Survey of Canada was to provide an advanced
framework of geoscience knowledge for mineral exploration and land-use management.
Bedrock mapping, geophysical surveys, and geochemical and geochronological analyses carried out in 2005 to 2011 in the far north of Manitoba showed diverse and complex rocks that record nearly two billion years of Earth history. Key advancements in understanding include a new stratigraphy and
chronology of at least four metasedimentary cover sequences in the Seal River Domain, some with high potential for economic uranium, gold, and/or rare-metal mineralization; and the identification of a Neoarchean greenstone belt in the Great Island area with known gold occurrences. The discovery of
remnants of ancient (3.5 Ga) cratonic lithosphere in the Seal River area also renders the region favourable for diamond exploration.
The Rae Province at 2.6 Ga: a sanukitoid storm on the Canadian Shield, Nunavut

Published: March 2024

Between 2.62 and 2.58 Ga, Rae Province was intruded from Lake Athabasca to Melville Peninsula (more than 1700 km) by mafic to felsic plutons (Snow Island Suite), and overlain by volcanic rocks that are now mostly preserved beneath Paleoproterozoic basins. The
Snow Island Suite was preceded by offshore arc volcanism and possible back-arc basin activity, with a U-Pb age peak at 2.635 Ga (Marjorie peak). About 50% of the Snow Island Suite is an infracrustal granitoid with K-enriched and tonalitic subtypes; the remainder lies on a sanukitoid spectrum.
The sanukitoidal rocks are dominantly orthopyroxene-bearing magnesian diorite and monzodiorite with Mesoarchean Nd model ages. Some isotopically juvenile Snow Island Suite and Marjorie peak mafic rocks also have strong sanukitoid or adakite trace-element signatures. Four important features in the
data are: 1) Marjorie peak mafic assemblages are prominent on the southeastern edge of Rae Province. Related nickel showings are present in south Rae Province Marjorie peak and early Snow Island Suite rocks; 2) U-Pb ages in the Snow Island Suite young toward the west edge of the province; 3) the
Committee Bay Block (north-central Rae Province) is distinctively rich in infracrustal Snow Island Suite migmatite and poor in Snow Island Suite sanukitoid rocks and in tonalite of any age; and 4) there is a marked shift from tonalite-rich infracrustal sources in south Rae Province to more
tonalite-poor sources in central Rae Province. The data are consistent with the Snow Island Suite, representing a continental magmatic arc segment, verging westward, with ponding of mafic magmas, inducing melting in the lower lithosphere to generate intermediate melts that ascended and induced
additional melting in the middle to upper crust to generate granite.
La longue vie du Batholite de Decelles, Pontiac, Québec: les grenats à notre rescousse!

Published: March 2024

Les granites peralumineux sont reconnus à l'échelle mondiale comme le produit magmatique final des cratons archéens. Cependant, leur durée, les conditions thermiques de leur mise en place, leur séquence de cristallisation, ainsi que les
liens avec l'évolution tectonométamorphique des roches encaissantes et les systèmes minéralisés en métaux précieux, de base, et rares sont peu connus. Le Batholite de Decelles (c. 2670-2620 Ma) exposé dans le sud-est du craton du Supérieur au Québec,
Canada est l'un des plus volumineux de la région, offrant une opportunité unique dmp;gt;'améliorer notre compréhension des conditions thermiques et de la mobilité des magmas et des fluides dans la croûte moyenne et supérieure. Nous présentons des nouvelles
datations Lu-Hf et des cartes dmp;gt;'éléments traces sur grenat de trois échantillons de granite du Batholite de Decelles. Les nouvelles dates de 2668 ± 4 Ma, 2663 ± 5 Ma, 2656 ± 7 Ma sont indifférenciables (considérant les incertitudes) des dates Lu-Hf sur
grenat et U-Pb sur monazite des unités métasédimentaires encaissantes. La cartographie des éléments traces in situ par LA-ICP-MS révèle une zonation compositionnelle systématique. Les grenats présentent un cur avec une zonation oscillatoire concentrique
en Li, P, Sc, Ti, Y, Zr, REE, Hf, Th et U; et une surcroissance marquée par des concentrations relativement élevées en MREE, HREE et V, et de faibles concentrations en Li, Ti, P, Sm, Zr, Hf et U par rapport aux curs. Les résultats indiquent une origine magmatique des grenats par
opposition aux grenats métamorphiques de la source avec une histoire de cristallisation complexe. Le contenu en éléments traces du grenat semble être contrôlé par des variations cinétiques de croissance et de diffusion à l'interface grenat-matrice, ainsi que
par la cristallisation de phases majeures et accessoires telles que la muscovite, la monazite, l'apatite et le zircon. Dans l'ensemble, le grenat du Batholite de Decelles date le début de la cristallisation magmatique et son contenu en éléments traces enregistre son histoire
complète. Les archives géochronologiques régionales indiquent une évolution commune des niveaux de croûte moyenne et supérieure avec un refroidissement progressif entre c. 2640 et c. 2620 Ma, associé à la migration et au refroidissement de fluides

Rhenium-rich molybdenite and Re-Os age of the Archean porphyry-style Don Rouyn deposit, Abitibi greenstone belt, Rouyn-Noranda, Québec
Authors: Mercier-Langevin P , Creaser R A , Goutier J , Kjarsgaard I
Published: March 2024

This report presents Re-Os dating of molybdenite from the Don Rouyn deposit and St. Jude breccia prospect in the Rouyn-Noranda mining district in the southern Abitibi greenstone belt, Quebec. Both have been described as porphyry-style, magmatic-hydrothermal
Cu-(Au-Mo) deposits associated with the Flavrian and Powell subvolcanic plutons based on the nature of the mineralized zones, their setting and available U-Pb age constraints. To further constrain the timing of mineralization, molybdenite was sampled at both sites for Re-Os geochronology. Although
the analyzed sample from the St. Jude prospect did not yield a realistic age, a molybdenite mineral separate sample from the Don Rouyn deposit yielded a reliable age of 2689 ± 11 Ma. Interestingly, the Don Rouyn molybdenite is distinguished by extremely high Re content (>5200 ppm Re)
that compares with that of the world's richest porphyry deposits. Based on the Re-Os age obtained in this study and limited descriptions of the deposit available in the literature, the Don Rouyn deposit is most likely associated with the emplacement of the Flavrian-Powell intrusive complex at
~2700 Ma, as suggested in previous studies. However, a younger timing of emplacement, comparable to other ca. 2682-2680 sub-alkaline to alkaline magmatic-hydrothermal Cu-(Au-Mo) deposits in the southern part of Blake River Group, although less likely, cannot be entirely ruled out based on the
available constraints and the molybdenite Re- Os age presented here.

ABSTRACT

Background:

Breast cancer awareness and early detection are critical for reducing the global burden of the disease. This study assessed breast cancer awareness among women in a high-altitude sub-Himalayan region of North India.

Materials and Methods:

A cross-sectional survey was conducted among women attending the gynecology outpatient clinic in a district hospital. A structured questionnaire was used to collect data on breast cancer knowledge, attitudes, and practices. Participants received posttest health education and counseling on breast cancer prevention strategies.

Result:

The study included 188 participants with a mean age of 31.0 ± 8.8 years. The findings revealed inadequate knowledge about breast cancer among a significant portion of the cohort. Misconceptions about risk factors, such as breastfeeding, oral contraceptive use, and past wrongdoings, were observed. Only half of the participants believed early-stage breast cancer could be effectively treated. Limited awareness of screening methods, including self-breast examination and mammography, was noted. Barriers to breast self-examination (BSE) included considering it unnecessary and lacking knowledge about its execution.

Conclusion:

This study highlights insufficient breast cancer awareness in the high-altitude sub-Himalayan region. Targeted interventions, including health campaigns and electronic media, should be prioritized to improve knowledge and promote early detection practices.

Authors: Bahadur Anupama , Mundhra Rajlaxmi , Pathak Anjali , Kumar Mukesh , Rundla Shri Ram , Suresh Gayatri
Published: March 2024

ABSTRACT

Background and Objectives:

Scrub typhus is an acute febrile illness transmitted by the bite of trombiculid mite in the larval stage. Scrub typhus is rare in pregnancy and there is paucity of data on the clinical outcome of scrub typhus during pregnancy.

Material and Methods:

We present five cases of scrub typhus complicating pregnancy who were admitted in the obstetric ward at AIIMS Rishikesh, India during the antenatal period for management.

Results:

The first patient presented at term pregnancy in semiconscious state while the rest were preterm between 31 and 34 weeks period of gestation. The age at presentation was 21–31 years. All five had febrile illness of >5 days’ duration along with cough. Fever investigations like blood culture, peripheral smear for malarial parasite, dengue serology, widal test, and urine culture were negative. Serology for scrub typhus was positive in all. Once diagnosis was confirmed for scrub typhus, patients were given the drug of choice azithromycin 500 mg twice daily for five days. Scrub typhus complicating pregnancy led to maternal mortality in one patient. It resulted in one preterm delivery, one intrauterine fetal death, and rest three were delivered at term with good perinatal outcome.

Conclusion:

Scrub typhus is common in endemic areas like Uttarakhand, India. It has a poor fetal outcome. If diagnosed early and treatment started, maternal and fetal prognosis can be favorable. As large case series are unavailable in literature, it is difficult to predict the course of disease which at times may be fulminant.

Published: March 2024

ABSTRACT

Background:

Ageing is a universal process. It is influenced by a person’s genetic makeup, lifestyle, and environmental factors. Nutrition plays a significant role in modulation of ageing. In developing countries like India, the health and nutritional status of the elderly population is not satisfactory.

Objectives:

The current study was done to assess undernutrition amongst the elderly population and to find the various associations with sociodemographic factors and social determinants.

Materials and Methods:

This cross-sectional study was done from February 2023 to July 2023 in rural area of District Gautam Buddha Nagar, Uttar Pradesh. The elderly participants who were 60 years of age and more and who met the inclusion criteria were selected by simple random sampling technique for the study. Undernutrition was assessed by Mini Nutritional Assessment Tool (MNA).

Result:

Out of the total of 400 elderly persons, 18% were found to be undernourished and 38% were at risk of undernutrition. The association between undernutrition and age group, gender, occupation, family type, living arrangements that is staying with family or not, financial dependence, any co-morbid illness, smoking, and physical activity was found to be significant.

Conclusion:

The present findings reveal that undernutrition is not an uncommon problem in the elderly, and further studies are needed in this regard.

ABSTRACT

Purpose/Background:

Nasal obstruction is a significant issue influencing the patient’s quality of life. Chronic nasal obstruction is frequently associated with other symptoms such as headache, sleep disturbance, and daytime sleepiness. This study aims to investigate the prevalence of nasal obstruction in Saudi Arabia and examine its effect on patients’ quality of life.

Methods:

This is a cross-sectional study conducted in Saudi Arabia. Data were collected using a self-administered combination of two previously validated questionnaires (the NOSE scale and the WHOQOL-BREF) translated into Arabic. The Mann–Whitney test was used to investigate the association between nasal obstruction prevalence and the participants’ QOL.

Results:

The study included 1039 participants from different regions of Saudi Arabia. The prevalence of nasal obstruction was 60.3% among the participants. Several factors significantly affected the prevalence of nasal obstruction, including sex, suffering from a chronic disease, having a family member with nasal obstruction, and using medications (P < 0.001 for all factors). A better score was shown in the four domains of the WHOQOL-BREF questionnaire by the participants who had no nasal obstruction: the physical health domain, psychological health, social relationships, and environment (P < 0.001 for all factors).

Conclusions:

Quality of life is affected by nasal obstruction. The subjective assessment is essential in evaluating the severity of nasal obstruction disease. It is recommended that healthcare providers use subjective tools combined with objective tools to assess the degree of nasal obstruction severity.

Authors: Moosavi Abdoulreza S. , Mahboobi Ashraf , Arabzadeh Farzin , Ramezani Nazanin , Moosavi Helia S. , Mehrpoor Golbarg
Published: March 2024

ABSTRACT

Background:

Artificial intelligence (AI) techniques have been ascertained useful in the analysis and description of infectious areas in radiological images promptly. Our aim in this study was to design a web-based application for detecting and labeling infected tissues on CT (computed tomography) lung images of patients based on the deep learning (DL) method as a type of AI.

Materials and Methods:

The U-Net architecture, one of the DL networks, is used as a hybrid model with pre-trained densely connected convolutional network 121 (DenseNet121) architecture for the segmentation process. The proposed model was constructed on 1031 persons’ CT-scan images from Ibn Sina Hospital of Iran in 2021 and some publicly available datasets. The network was trained using 6000 slices, validated on 1000 slices images, and tested against the 150 slices. Accuracy, sensitivity, specificity, and area under the receiver operating characteristics (ROC) curve (AUC) were calculated to evaluate model performance.

Results:

The results indicate the acceptable ability of the U-Net-DenseNet121 model in detecting COVID-19 abnormality (accuracy = 0.88 and AUC = 0.96 for thresholds of 0.13 and accuracy = 0.88 and AUC = 0.90 for thresholds of 0.2). Based on this model, we developed the “Imaging-Tech” web-based application for use at hospitals and clinics to make our project’s output more practical and attractive in the market.

Conclusion:

We designed a DL-based model for the segmentation of COVID-19 CT scan images and, based on this model, constructed a web-based application that, according to the results, is a reliable detector for infected tissue in lung CT-scans. The availability of such tools would aid in automating, prioritizing, fastening, and broadening the treatment of COVID-19 patients globally.

Authors: Swetha Pavuluri Sai , Gupta Kavita , Saha Swarnatrisha , Panda Sandip K. , Behera Bijayini
Published: March 2024

ABSTRACT

Introduction:

Infections in haemodialysis (HD) patients are an important cause of morbidity, hospitalization, and mortality. Patients undergoing HD are more prone to develop bacterial infections by multidrug-resistant organisms (MDROs).

Objectives:

This study is aimed to detect MDROs colonization in HD patients and its associated risk factors and outcome.

Methodology:

A total of 62 nasal swabs and 124 rectal swabs were collected from 62 patients coming to the haemodialysis unit from of March to May 2021 and were further screened for MRSA, VRE and CRE.

Results:

Out of 62 patients, 22.59% showed the presence of methicillin-resistant staphylococcus aureus (MRSA) while VRE was present in four patients (4/62). CRE was found as 24.2% (15/62). Duration of dialysis was found as a significant risk factor-associated MRSA carriage, Whereas Charlson index and drug and medication were found as significant risk factor for VRE carriage.

Discussion & Conclusion:

HD patients are particularly vulnerable to life threatening infections. Therefore, continuous epidemiological surveillance for these MDROs, including genotypic analysis and implementation of adequate decolonization strategies, is crucial and will reduce the possibility of autoinfection as well as disrupt transmission of multi-resistant isolates to others.

Published: March 2024

ABSTRACT

Context:

Literature regarding hydatid disease in children is sparse.

Aims:

To highlight the peculiarities in the clinical pattern of pediatric hydatid disease (PHD).

Settings and Design/Materials and Methods:

Data were collected retrospectively from all children aged <18 years who presented to our tertiary care institute from July 2021 to June 2023 with hydatid disease involving any organ.

Statistical Analysis Used:

Simple statistical analysis involving sums, means, averages, and percentages.

Results:

Four of the 10 cases (40%) involved the lung, while only 2 (20%) involved the liver. There were five females and four males with an age range of 2–17 years. Four of the cases had primary extrahepatic extrapulmonary hydatid disease (40%), two involving the pancreas, one in the rectouterine pouch, and one intracranial.

Conclusions:

The clinical pattern of PHD is different from that of adults. Pulmonary echinococcosis is more common than hepatic involvement. Primary extrahepatic extrapulmonary hydatid disease is also more common in children than previously thought. A cystic lesion anywhere in a child warrants a differential of hydatid disease.
Glycopyrrolate as an Adjunct in the Management of Anastomotic Leak Following Repair of Esophageal Atresia: A Clinicoradiological Perspective
Authors: Gupta Rahul , Chopra Ashok K. , Dogra Neelam
Published: March 2024

ABSTRACT

Context:

Anastomotic leak after primary repair of esophageal atresia (EA) with tracheoesophageal fistula (TEF) is a well-known complication and can represent a challenging clinical scenario.

Aims:

The present study aimed to evaluate the role of glycopyrrolate as an adjunct in the treatment of anastomotic leak after primary repair of EA Vogt type 3b.

Settings and Design:

A retrospective study was carried out in our tertiary care teaching institute from January 2015 to December 2022.

Materials and Methods:

Neonates with EA with distal TEF with primary repair who had developed anastomotic leak, managed by the author(s), were studied. The study included patients with major, minor, and radiological leaks. Glycopyrrolate was administered in the dose of 4 μg/kg 8 hourly. The outcomes of the study were either resolution or progression of the leak.

Results:

There were 21 patients who were managed with glycopyrrolate in addition to the classical treatment of the anastomotic leak following repair of EA with distal TEF. The male: female ratio was 1:1.1. All the cases had anastomotic leaks with either clinically detectable in the chest tube (15) or radiological leak (6). The leaks were detected early in patients with major leak (mean = 3.2 ± 0.84 days) compared to minor leak (mean =4.9 ± 1.29 days). Radiological leaks were detected in all the neonates on postoperative day 7. In five patients with major leak, there was a negligible reduction in the amount of chest tube output, and were subjected to diversion procedures. There were a total of three deaths out of five in this group. In 10 patients with minor leak, there was complete resolution of anastomotic leak in eight patients (80%); there was one patient each with mortality and diversion procedure. The patients with a radiological leak (6) did not show any deterioration, and they were fed 1–5 days after the esophagogram.

Conclusions:

Glycopyrrolate may be an advantageous postoperative adjunct in the management of minor and radiological leak after tracheoesophageal repair.
Ovulation induction in polycystic ovarian syndrome: A review to contemporary approaches
Authors: Chouhan Preeti , Garg Ayush Kumar
Published: March 2024

Polycystic ovarian syndrome (PCOS) is an endocrine condition that impacts women’s reproductive capabilities and causes them to be infertile. Anovulation is the most common cause of PCOS infertility, although it is not alone. The ongoing hormonal imbalance causes complications such as cysts and an abnormal menstrual cycle, leading to infertility. A few of the reasons for PCOS have been discovered as several potential genes. PCOS is a heterogeneous syndrome that primarily affects women between the ages of 18 and 44 years. There are several methods of ovulation induction (OI) that can be made to make females fertile. Recent research has been conducted on OI using mediation, surgery, lifestyle changes, symptom, and treatment. On the other hand, each of these methods was limited to single or single-pathway research. Because PCOS is complex involving a gene regulatory milieu, it may be prone to the transient, self-limiting occurrence of endometrial receptivity. To induce ovulation in PCOS patients, genomic-based assessment is needed for therapeutic purposes.

Authors: Al-Khikani Falah Hasan Obayes , Al-Hussainy Ahmed Danbous Obayes , Hussein Aliaa Zaraa Allah , Alshamary Rasha Salih Mahdi
Published: March 2024

Background:

The SARS-CoV-2 associated with bacterial infection represents a serious public health challenge. Recently, there is a remarkable increase in the number of researches that confirms the effect of Helicobacter pylori on pulmonary diseases.

Aim:

The goal of this research was to see how H. pylori affected the presentation of COVID-19 infections as a prospective risk factor.

Materials and Methods:

This research was conducted in Babylon, Iraq, from January 1, 2022, to March 5, 2022. A total of 180 people were engaged in this study, with 90 patients identified with SARS-CoV-2 by polymerase chain reaction testing and 90 people serving as a control group. Antibody screening assays on blood samples were used to look for antibodies against H. pylori. The samples were processed for complete blood count and ABO blood group.

Results:

COVID-19 infection was more frequent in females than in males, especially between 31 and 45 years. When compared to healthy people, COVID-19 patients had a higher white blood cell count (P = 0.0001) and a lower lymphocyte count (P = 0.0001). H. pylori and COVID-19 have been found to have a strong relationship, especially in females. When comparing patients to healthy people, blood group A is the most common.

Conclusion:

People with H. pylori infections are considerably more sensitive to COVID-19 than people without H. pylori infections (P = 0.011). In combination with SARS-CoV-2, IgG for H. pylori might be a risk factor.

Influence of subclinical hypothyroidism on cardiovascular disease risk in geriatric population: A cross-sectional study
Authors: Nitha N. S. , Rao Satish B. , Shenoy Ramya , Sowndarya K. , Hegde Anupama
Published: March 2024

Background:

Changes in thyroid function are common in geriatric population. Thyroid-stimulating hormone (TSH) concentration increases in healthy elderly individual, whereas total and free thyroxine (FT4) concentrations remain unchanged presenting like subclinical hypothyroidism (SCH). Thyroid hormones influence the normal functioning of heart and vascular physiology. Changes in cardiac function and lipid parameters due to alteration in thyroid function could predispose the elderly population to increased cardiovascular disease (CVD) risk.

Materials and Methods:

The present cross-sectional study included 75 apparently healthy elderly patients who were grouped as SCH (n = 30) or euthyroid (ET) (n = 45) based on their thyroid profile. Serum high-sensitivity C-reactive protein (hsCRP) was evaluated by immunoturbidimetric method. The laboratory data of thyroid profile and lipid profile were collected, and the demographic features of the patients were noted from the case sheet. CVD risk score was calculated using Framingham 10-year CVD risk calculator (Atherosclerotic-CVD).

Results:

There was no significant difference in age between cases and controls. Body mass index was found to be elevated in SCH. T4 was found to be slightly higher in the cases when compared to that of controls. The median value of TSH was found to be higher in patients with SCH. CVD risk score increased significantly in SCH group. A significant positive correlation was found between the hsCRP and CVD risk in subclinical hypothyroid as well as in ET group. A significant negative correlation was found between TSH and CVD risk scores in ET patients.

Conclusion:

SCH is associated with an increased risk of CVD risk among the older adults with an elevated level of TSH.

Authors: Rajkumari Bigyabati , Rajkumar Victor , Chingakham Debeshwar Singh , Bishwalata Rajkumari
Published: March 2024

Background:

There are various studies on coronavirus disease-2019 (COVID-19) from globally which are mainly focused on respiratory and other medical manifestations of the disease. There are few studies on ocular manifestations in COVID-19 and post-COVID-19 patients.

Objectives:

We aim to investigate the ocular manifestations of hospitalized post-COVID-19 patients at a tertiary care institute in the North Eastern part of India.

Materials and Methods:

This cross-sectional study was conducted among hospitalized post-COVID-19 patients 18 years and above during July 1, 2021–December 31, 2021. A universal sampling method was employed. A structured pro forma was used for data collection along with detailed ocular examination. Descriptive statistics were generated from collected data. Approval of the study was obtained from the institutional ethics committee.

Results:

A total of 105 patients were included in the study with ages ranging from 18 to 85 years and males constituting 63.8%. Around two-thirds of the patients (70, 66.7%) had not received any vaccination. Chest X-ray showed bilateral moderate consolidation in 59 (56.2%) patients. Twelve (11.4%) patients developed ocular signs and symptoms. Dry eye, redness of the eye, dimness of vision, itching, blurring of vision, and discharge from the eyes are some of the symptoms encountered. Two patients developed subconjunctival hemorrhage, one patient had a retinal hemorrhage and exposure keratopathy was detected in one patient.

Conclusion:

In this study, 11.4% of hospitalized post-COVID-19 patients have ocular manifestations. Post-COVID-19 syndrome could affect the eyes thus necessitating meticulous follow-up of patients who recovered from COVID-19.
Morphometric Analysis of the Mental Foramen and Mandibular Canal Using Orthopantomogram and Cone-Beam Computed Tomography: A Comparative Radiographic Study
Authors: Pauly Geon , Ashok Navami , Kashyap Roopashri Rajesh , Kini Raghavendra , Rao Prasanna Kumar
Published: March 2024

Purpose:

A pre-operative radiographic evaluation of the morphometry of the mental foramen (MF) and its true relationship to the alveolar crest (AC) and the mandibular canal (MC) and its true relationship to the roots of the mandibular third molar (M3) would help in negating possible sensory impairment during surgical procedures.

Materials and Methods:

A retrospective study of 50 cone-beam computed tomography (CBCT) and orthopantomogram (OPG) images of the same patients were selected. The diameters of MF, MC, distance between AC-MF and distance between apices of 3rd molar-MC were measured.

Results:

On OPG and CBCT, the mean values of the vertical diameter of MF were found as 3.044 mm and 2.948 mm, whereas the mean horizontal diameters obtained were 3.033 mm and 3.023 mm, respectively. The mean values of the diameter of MC were measured at 2.750 mm and 2.894 mm, respectively. The mean values of distance from M3 apex to MC and distance from AC to MF were obtained as 1.371 mm and 1.748 mm and 14.715 mm and 13.656 mm, respectively.

Conclusion:

The difference in the mean values of the diameter of the MF was statistically insignificant. The rest of the parameters gave us values which were statistically significant (P < 0.05). Therefore, in an era of steadfast increased use of dental implants and frequent need for planning disimpactions, the use of CBCT can truly help us dislodge the limitations of two-dimensional imaging and thereby help us carry out such surgical procedures more efficiently and with no or minimal complications.

Published: March 2024

Aim:

The survey aims to assess the degree of awareness and knowledge of periodontal plastic and aesthetic surgery amongst house surgeons.

Materials and Methods:

A questionnaire-based study was conducted to assess the degree of awareness and knowledge of periodontal plastic and aesthetic surgical procedures amongst 80 house surgeons in KMCT Dental College, Manassery, Kerala. A questionnaire containing 10 questions in English was prepared for data collection and distributed to 80 interns through Google form. Questions were formulated based on basic knowledge about mucogingival problems and their treatment modalities, understanding of various terminologies, indications for mucogingival procedures and awareness about prognosis and treatment outcome after mucogingival procedure. The possible options chosen by the participants were tabulated and the percentile for each question was represented using pie charts.

Results:

Amongst the 80 participants, around 80% of participants were having basic knowledge about mucogingival problems and their treatment modalities. About 48% of participants were aware of the indications of periodontal plastic and aesthetic surgical procedures and 85% of the participants knew about the prognosis and treatment outcome of these surgical procedures.

Conclusion:

Mucogingival procedures or periodontal plastic surgery involves the correction of soft-tissue defects involving the periodontium and frenum. The present study was able to assess the degree of knowledge of periodontal plastic surgical procedure amongst house surgeons. The awareness and knowledge of periodontal plastic and aesthetic surgery amongst house surgeons were good however it could be improved.

Authors: Lesmanawati Fanny Evasari , Windura Carolus Aldo , Saputro Iswinarno Doso , Hariani Lynda
Published: March 2024

Objectives:

The objective of this study was to analyze all available research on the application of autologous fat grafting (AFG) and adipose-derived stem cells (ADSC) to present evidence-based recommendations, particularly in the clinical treatment of acute burns and burn-related scars.

Materials and Methods:

We conducted a systematic search of PubMed, COCHRANE, and EMBASE, as well as a manual search of previous reviews’ reference lists up. The risk of bias (RoB) was assessed using RoB 2.0 and ROBINS-I, where appropriate.

Results:

Six eligible studies were selected (2 randomized clinical trials [RCT], 1 retrospective cohort, and 3 experimental studies) with subjects ranging from 3 to 100. Only one study evaluated the use of AFG for acute burns. Improvements in wound healing, vascularization, scar characteristics, and tissue architecture were generally observed in some studies, supported by molecular markers, while one study reported nonsignificant results. Subjective patient satisfaction was reported to have improved. Functional outcomes improvement in the treated regions was minimal. However, study heterogeneity arose mainly from treatment protocols. Cautious results interpretation due to potential bias, especially in selection and confounding domains, and limited clinical trials are important to note. More studies are needed to evaluate.

Conclusion:

AFG and ADSC hold potential as valuable treatment options for burn-related scars, supported by a body of evidence, but further well-designed RCT are needed. The efficacy of acute burn settings is yet to be further evaluated since evidence is limited.

Published: March 2024

In precision agriculture, one of the major problems is the need for a dense sampling grid. A solution to this problem has been the generation of management zones and the correlation between them. This work aims at defining management zones for a papaya culture using the fuzzy C-means grouping method, based on the following soil attributes: phosphorus, calcium, magnesium and potassium; and base saturation. The work was conducted in an approximately 1.2 ha area planted with a commercial culture of Carica papaya L. cultivated in typical Argisol found on the coastal terraces, in the municipality of São Mateus, ES, Brazil. The management zones were defined by the proposed method, based on the following analyses: soil chemical parameters P, Ca, Mg, and base saturation (V), analyzed together; soil chemical parameters P, Ca, Mg, and V, analyzed separately; and, the following combinations of soil chemical attributes Ca-Mg, Ca-V, Ca-Mg-V, P-Ca, P-Mg, P-V, P-Ca-Mg, P-Ca-V, Mg-V, and P-Ca-Mg-V. The generated management zones facilitated an understanding of the spatial variability of the attributes in the study area and the observed similarities between management zones generated from different attributes. In addition, the data were influenced especially by the P and V% attributes.
Keywords: Carica papaya L, geostatistics, grouping analysis, precision agriculture.
Smooth DG algebras and twisted tensor product
Authors: Orlov Dmitri Olegovich
Published: March 2024

The twisted tensor product of DG algebras is studied and sufficient conditions for smoothness of such a product are presented. It is shown that in the case of finite-dimensional DG algebras, applying this operation offers great possibilities for constructing new examples of smooth DG algebras and algebras. In particular, examples are given of families of algebras of finite global dimension with two simple modules that have non-trivial moduli spaces.

Introduction: The Google Chrome extension Protractor (GCE-P) by Ben Burlingham is a small software application where it can be used in a telerehabilitation setting by physical therapists and clinicians to measure active range of motion (AROM). This study
is directed to determine the concurrent validity, intra- and interrater reliability of the GCE-P as compared to the universal goniometer (UG), in measuring the hip internal rotation (IR) and external rotation (ER) in a seated position.

Methods: This study is a descriptive validation study with crossover design of 54 recruited healthy participants. The hip AROM IR & ER were first measured with a UG to set a standard, and then was digitally measured via Google Meet using GCE-P, all were done in 3 trials. The following were used for data analyses: Pearson moment correlation coefficient, intraclass correlation coefficient and Blant-Altman analysis in sitting IR and ER, with alpha set at 0.05.

Results: The GCE-P had a high agreement with the UG, with values of concurrent validity in hip IR (r=0.92) and ER (r=0.88). With a minimal mean difference of (3.44o) in hip IR and (0.30o) in hip ER, using Blant-Altman analysis. The GCE-P also had good intra-rater reliability, measured via intraclass correlation coefficient (ICC), with values for hip IR of (ICC=0.92, 95%CI=0.87-0.95), and for hip ER of (ICC=0.94, 95%CI=0.90-0.96). Interrater reliability was also shown to be excellent with values of ICC=0.91 (95%CI=0.84-0.94) in hip IR, and ICC=0.88 (95%CI=0.81-0.93) in hip ER.

Discussion: The Google Chrome extension Protractor is accurate and reliable for measuring hip joint AROM in IR & ER. This is valid to be used in a telerehabilitation setting during consultations, and initial evaluations within the context of quarantine protocols.

A JUDICIALIZAÇÃO DA SIMETRIA
Authors: Baia Breno , Santos Gabriela Sena dos
Published: March 2024

O objetivo do artigo é analisar a jurisprudência mais recente do STF sobre a simetria com base no viés institucionalista que tem marcado a investigação sobre judicialização da política no Brasil. Procedimentalmente, o trabalho caracteriza-se como uma pesquisa de natureza empírica que emprega o marco teórico da judicialização da política, popularizado por Werneck Vianna (1999/2007), bem como o da intepretação da simetria proposto por Araújo (2009), para analisar 60 ADIs propostas em face de normas constitucionais estaduais durante os anos de 2007 e 2020. O estudo conclui que não há uma mudança significativa no que diz respeito à tese da simetria, que continua forte na jurisprudência do STF, uma vez que a maioria dos casos foi julgada procedente e com quase nenhum voto divergente. Ademais disso, foi possível identificar o uso estratégico da simetria como veículo de oposição política formulada por partidos, a regionalização da judicialização da simetria no Norte e Nordeste e uma concentração temática no sentido da moralização da política regional.
Descentralización político-administrativa y democracia en México
Authors: Pérez Ramírez Rigoberto
Published: March 2024

El presente trabajo tiene como objetivo analizar la relación causal entre la descentralización político-administrativa y la democracia en México, como un proceso histórico-dinámico que busca fortalecer la autonomía regional y local a través de reformas que legitimen un nuevo orden democrático, el cual depende múltiples y variados factores que acompañan muchos planteamientos que originan una realidad empírica confusa. Para dilucidar sobre esta confusión, se emplea el método descriptivo-analítico revisando la literatura clásica y contemporánea sobre la base de la idea de democracia y descentralización, así como, el estudio empírico que proporciona el Índice de Desarrollo Democrático de México 2022, el cual vincula la calidad de la democracia y la capacidad institucional de la gestión democrática en la provisión de servicios públicos. A pesar del avance procedimental democrático del país las dificultades que los gobiernos subnacionales y locales para consolidar instituciones y mecanismos que propicien cambios en sus respectivas administraciones subsisten por las restricciones financieras y administrativas determinadas por la agenda de la política nacional.
