Published: October 2023

Natural fiber reinforced polymeric composites perform poor in mechanical and thermal properties at elevated temperatures due to the cellulose and hemicellulose contents of natural fiber start degrading at elevated temperature. In this research work, flame retardancy and thermal stability of treated and untreated kenaf fiber reinforced epoxy composites have been experimentally investigated and reported. Two composite laminates, one with 6 % NaOH Alkali treated and another with untreated woven kenaf mats, were fabricated by hand lay-up technique followed by compression molding with 40 % fiber weight fractions. Flame retardancy test and various thermal characteristics studies such as thermogravimetric analysis (TGA), differential scanning calorimetry (DSC), heat deflection temperature (HDT), and morphological analysis via scanning electron microscopy (SEM) tests were carried out. The results showed that alkali treated kenaf fiber composite achieved V0 fire retardancy grade. The major weight losses, 86 % and 75.5 % for untreated and treated composites respectively were recorded between 300 °C and 450 °C. 13.6 % increase in HDT was noted for treated composite with 0.25 mm deflection at 0.45 MPa pressure condition. Thus the composite laminate with 6 % NaOH alkali-treated kenaf fiber achieved the best thermal stability with less degradation which is more suitable for automobile and aerospace applications.
The structural human and semiotic animal: between pride and humiliation
Authors: Švantner Martin
Published: October 2023

The main theme of the article, which by genre falls into the area of semiotically influenced philosophy, is a reflection on the relationship between the human and the non-human, using two partial but parallel discourses. The first discourse is the perspective of general semiotics, which is defined in the article on the basis of two distinct forms of rationality that, in different guises, still intervene in debates about the nature of the humanities and social sciences today. The first form of this rationality is semiological, which can be classified under the encyclopaedic rubric of structuralism, and which has its main source of inspiration in general linguistics and its continuation in philosophical anti-humanism. The second perspective has its origins in Peirce’s logicist theory of the sign and his pragmatist metaphysics, and opens up thinking about the sign, the human, and the non-human to a non-language-centric view of the world. Despite their demonstrable theoretical and methodological incompatibility, the present text treats them as incompatible but largely complementary perspectives. It is in their mutual exposition that one can see the moments in which the view of modern human as a semiological and semiotic animal takes shape. The text brings this fundamental and founding theoretical schism into focus by examining two images from post/modern art: Ted Chiang’s “The Great Silence” and Jorge Luis Borges’ “Averroës’s Search.”

A series of new benzoxazole-hydrazone and benzoxazole-1,3,4-oxadiazole derivatives have been designed, synthesized and evaluated as cytotoxic agents toward human A549 lung cancer cells. Compounds 3d, 3e, 5b, 5c, 5d and 5e were the most potent compounds with IC50 values of <3.9, 10.33, 11.6, 5.00, <3.9 and 4.5 μg/mL, respectively, which are higher than reference drug cisplatin (IC50 = 19.00 μg/mL). The flow cytometry-based apoptosis detection assay was performed to determine their effects on apoptosis in A549 cells. All tested compounds induced apoptosis in A549 cell line.
Teachers’ professional development for cooperative learning: A constructive controversy between long-term versus short-term professional development
Authors: Liebech- Lien Beathe , Hammar Chiriac Eva , Davidson Neil
Published: October 2023

Abstract:

Previous scientific research has recognised the pedagogical model of cooperative learning (CL) as a best-practice pedagogy, which facilitates students’ academic and social learning. Teachers are crucial for implementing CL in the classroom. While they value the method, they often find it complex and challenging to use. Thus, it is crucial to support effective CL professional development (PD) for teachers. Various approaches, forms and lengths of PD in CL are available for teachers, and long- and short-term approaches have been debated in the literature. Based on the perspective of constructive controversy, the goal of this study is to examine teachers’ PD in CL, with a particular focus on long- and short-term PD. Drawing on our different perspectives and experiences with long- and short-term PD in CL, we aim to contribute knowledge that can support teachers’ learning and implementation of CL. To provide insights and reflections along with theoretical findings, we utilise a narrative approach, with one narrative on long-term PD and one on short-term PD. One issue that becomes clear is the lack of a consensus on what counts as PD for teachers, as PD is a holistic multidimensional construct. We propose four common characteristics that should be considered in developing successful PD regardless of the CL approach or the length of the PD: 1) It enables participating teachers to acquire a shared understanding and knowledge of the theoretical framework of CL; 2) It supports teachers in taking ownership of CL; 3) It involves collaboration (in different forms); and 4) It includes support structures. While both long- and short-term PD can support teacher learning, how the time is used is the most important factor for a successful outcome. Hence, short-term PD is better than no PD at all.

Authors: Cao Chengjun , Bing Jian , Liao Guojian , Nobile Clarissa J , Huang Guanghua
Published: October 2023

Candida species, the most common fungal pathogens affecting humans, cause not only superficial infections but also life-threatening invasive infections, particularly in immunocompromised individuals. Although Candida albicans remains the most frequent cause of candidiasis, infections caused by non-albicans Candida species have been increasingly reported in clinical settings over the past two decades. Recently, species of the Metschnikowiaceae clade including the “superbug” Candida auris and other members of the Candida haemulonii species complex have attracted substantial attention for their multidrug resistance and high rates of transmission in clinical settings. In this review, we summarize the epidemiology, biology, virulence, and drug resistance of the C. haemulonii species complex and discuss potential reasons for the recent increase in the prevalence of infections caused by non-albicans species in clinical settings.

doppelganger symbolism at the dawn of French Cinema
Authors: Martins Ana Taís , Fantinel Danilo
Published: October 2023

The pioneers of French cinema founded the audiovisual language which allows narratives with moving images, while developing techniques of capture and editing, recording and representation, sequence and superposition of shots, multiple exposure frames, of appearance or disappearance. For Morin, this ghostly duplication of the world by the cinematographic image is motivated by the symbolic image of the double, which brings together dreams and cinema. In this article we discuss such symbolism in empirical reference objects of this initial moment of the Seventh Art.

Published: October 2023

Any state-of-the-art integrated development environment (IDE) should provide software developers with services for quick and correct code transformation. Such services can be used both for program refactoring to improve its quality and for quick fixing of syntax errors in source code. This paper presents the method of constructing a subsystem that makes it possible to create the services described above and also has the property of fast extensibility to support different programming languages. The method of transformation of Program Structure Interface (PSI) - a special data structure, which provides API for development of IDE-services, is proposed. Besides, a method of generating types for PSI in accordance with the syntax of the supported programming language is proposed. The approach is developed for a multi-language platform of a large telecommunications company. Refactoring and Quick Fix features are implemented using on the proposed generator for two IDEs: a Python IDE and a Java IDE.

Published: October 2023

Gymnotiform electric knifefishes are an important yet undersampled component of the Neotropical aquatic biota. We report on the gymnotiform fauna of the Tres Fronteras region located at the triple border of Brazil, Colombia, and Peru in the biodiverse western Amazon. The presence of at least 33 species of gymnotiforms in the Tres Fronteras region is validated from recent sampling efforts and the review of previously collected materials. A key is provided for the identification of the species that have been collected from the region. We comment on the diversity of habitat utilization and intraspecific colour variation of some species.

Published: October 2023

Coliform bacteria are essential variables for assessing riverine water quality. In this study, the faecal indicator bacteria (FIB) in relationship with some physico-chemical variables were investigated during the period 2020-2022 for four urban rivers (To Lich, Lu, Set, and Kim Nguu) in the inner Hanoi city to provide the updated water quality of these rivers. The results demonstrated severe faecal coliforms contamination in riverine waters compared to the permissible values of the Vietnam technical regulation for surface water quality, QCVN08-MT:2015/BTNMT column B1. Nutrients (ammonium and phosphate) concentrations and dissolved oxygen (DO) values exceeded the permissible values, whereas pH was within the standard. The Pearson analysis demonstrated the significant positive correlation between total coliforms (TC) and Escherichia coli (EC) densities and ammonium concentration in the riverine water. Besides, these variables were higher in the dry season than the rainy one for all sites observed. All these reflect the critical role of the point sources, notably domestic wastewater inputs in the four river basins. Considering these rivers' deteriorating condition, developing an effective wastewater treatment system is necessary for the rivers in Hanoi.
The activities of Priest Peter Nortamo on the reunification of the Finnish and Russian Orthodox Churches
Authors: Simonov V. V. , Nikitin S. S.
Published: October 2023

Russian Orthodox Diocese of Finland, taking advantage of the church and international policy, illegally transferred to the Patriarchate of Constantinople in 1923 and its relations with the Russian Church were interrupted for two decades. At the end of the Great Patriotic War, a movement for the reunification of the two churches began, but there was no unity within the Finnish Church on this issue, and the efforts of the Moscow Patriarchate’s hierarchy led to limited results. The article reveals the history of the participation of Petter Nortamo, a Finnish pastor who converted to Orthodoxy and tried to speed up the process of the return of the Finnish Archdiocese to the Russian Orthodox Church, unknown to Russian scientists. One of the characteristic features of his activity was the active involvement in this process of political parties and associations of socialist orientation, as well as the press (in particular, the Democratic Union of the People of Finland). The article disputes the reading of this story by the Finnish historian Juha  Riikonen,  who  sees  this  primarily  as  a  political  background.  Nortamo’s  active  contacts  with  Metropolitan Grigory (Chukov) and Patriarch Alexy I, his ordination to holy orders in Leningrad indicate that the church component was decisive in his activities. However, Nortamo’s efforts were not enough to solve the problem of the relationship between the Finnish and Russian Orthodox Churches, and his death coincided with the end of such attempts. The Patriarchate of Constantinople played a significant role in freezing the process of church reunification. To this day, the figure of Nortamo remains unknown in Russian historical science.
Synodic of the Studenitsa Monastery as a historical source
Authors: Beliankin Yu. S.
Published: October 2023

The article analyzes the content of the handwritten Synodic, which has belonged to one of the most important Serbian monasteries — Studenica — since the middle of the XVII century. Such manuscripts are known in single copies in the repositories of the Balkan Peninsula and Greece, all of them reflect the history of Russia’s relations with the South Slavic and other Orthodox peoples of southern Europe during the reign, mainly, of the Romanov dynasty.

The value of this manuscript is that it marks the beginning of the establishment of the regular practice of the clergy of the Studenitsa for alms in Russia, which lasted a century. Synodic contains a wealth of material on the genealogy of many Russian, Ukrainian, Serbian and other families that played a historical role in the events of Southern and Eastern Europe in the second half of the XVII-XVIII centuries.
The Use of Shear-Wave Ultrasound Elastography in the Diagnosis and Monitoring of Musculoskeletal Injuries
Authors: Horvat Urša , Kozinc Žiga
Published: October 2023

Ultrasound elastography is a valuable method employed to evaluate tissue stiffness, with shear-wave elastography (SWE) recently gaining significance in various settings. This literature review aims to explore the potential of SWE as a diagnostic and monitoring tool for musculoskeletal injuries. In total, 15 studies were found and included in the review. The outcomes of these studies demonstrate the effectiveness of SWE in detecting stiffness changes in individuals diagnosed with Achilles tendinopathy, Achilles tendon rupture, rotator cuff rupture, tendinosis of the long head of the biceps tendon, injury of the supraspinatus muscle, medial tibial stress syndrome, and patellar tendinopathy. Moreover, SWE proves its efficacy in distinguishing variations in tissue stiffness before the commencement and after the completion of rehabilitation in cases of Achilles tendon rupture and patellar tendinopathy. In summary, the findings from this review suggest that SWE holds promise as a viable tool for diagnosing and monitoring specific musculoskeletal injuries. However, while the field of ultrasound elastography for assessing musculoskeletal injuries has made considerable progress, further research is imperative to corroborate these findings in the future.

Authors: Babu Ravi Mahesh , Satamraju Krishna Prasad , Gangothri Bellagubbala Neeharika , Malarkodi Balakrishnan , Suresh Chintalapudi Venkata
Published: October 2023

The Internet of Things (IoT) is a promising technology inspiring industries and the public alike with
its broad spectrum of applications adding intelligence to real-life objects. Due to its resource-limited
nature and heterogeneity of the devices in IoT networks, data security and energy consumption is
an important issue. Security for sensitive data in the network is paramount, and privacy and access
control mechanisms should be in force. Also, for reliable application services, optimized network
operations in terms of energy are demanding needs. This paper proposes a novel energy optimization
and node deployment strategy by amalgamating genetic algorithm (GA) for energy optimization and
mixed integer linear programming (MILP) for strategic node replacement. GA-based optimization
focuses on improving residual energy of the nodes in the network, thereby enhancing the network
lifetime. The MILP-based node deployment strategy focuses on selecting a minimum node set while
still servicing the entire network area. The potentiality of the blockchain is used in the model to provide
data privacy and access control to sensitive data. The proposed model is then compared with state-ofthe-
art models to validate the performance in terms of network lifetime and throughput. It is evident
from the results that the proposed method outperforms existing models and provides reliable and viable
solutions for many applications running on IoT networks.

Published: October 2023

This study aimed to reveal resistance levels of Aphis gossypii Glover, 1877 (Hemiptera: Aphididae) populations against dimethoate, λ-cyhalothrin and chlorpyrifos-ethyl used in cotton fields in Çukurova region in Adana province in Türkiye. Populations were collected from 16 locations between 2020 and 2021. Bioassay, biochemical and molecular methods were used to determine resistance. Six populations were resistant according to the susceptible (Toktamış) population with leaf dip discriminating dose bioassays. Compared to the susceptible population, four populations were found at decreased susceptibility (DS) resistance levels to dimethoate and one population to chlorpyrifos-ethyl. . Only two populations resistance ratio were detected in MR (Moderate resistance) category to chlorpyrifos-ethyl. Resistance levels of other populations were observed as S (susceptible) category. Resistant populations had higher acetylcholinesterase, glutathione-S transferase and cytochrome P450 monooxygenase enzyme activities in biochemical analysis. The carboxylesterase gene transcription levels were higher in resistant populations. S431F and Kdr (knockdown) mutation were determined by the PCR-RLFP method, which is effective in organophosphate and pyrethroid insecticides resistance and 17% and 100% recessive alleles were detected in populations. The biochemical and mutation-induced resistance to dimethoate and chlorpyrifos-ethyl was detected. These results will contribute to developing strategies for resistance management of A. gossypii.
Treatment of postural headache occurred 26 days after spinal pain procedure - A case report -
Authors: Park Seoyoung , Lim Yun-Hee , Yoo Byung Hoon
Published: October 2023

Background: Cerebrospinal fluid (CSF) leakage may cause intracranial hypotension and postural headache. Secondary intracranial hypotension may result from an iatrogenic dural puncture or traumatic injury associated with pain procedures.Case: A 45-year-old man developed a headache 26 days after spinal pain procedure. Headache was characterized as postural, worsening with standing or sitting and improving while lying down. The pain did not resolve despite the administration of oral and intravenous analgesics. A spinal magnetic resonance imaging revealed epidural venous congestion and a suspicious CSF leak around the left L4/5 level. The patient received an epidural blood patch (EBP), the headache improved dramatically, and the patient was discharged.Conclusions: Delayed postural headaches may not be directly related to pain management. Nevertheless, intracranial hypotension related to pain management should be suspected even in this case. If confirmed, quickly applying an EBP is an effective treatment option.
Most Online Resources for Home Suture Removal are Poor in Quality
Authors: Fan Emily , Ho Bao Vincent K. , Seger Edward W. , McClure Spencer P. , Rajpara Anand
Published: October 2023

Introduction. At home suture or staple removal can be stressful for patients and may lead some to seek out additional instruction via online resources as an adjunct to what was explained to them by their provider. The purpose of this study was to examine the existing online resources available to patients who may be interested in or have been instructed to remove sutures at home after a simple procedure such as a skin biopsy or excision.
Methods. A systematic search was conducted using internet search engines to identify videos and webpages targeting at home suture removal instruction. The DISCERN instrument was used to evaluate the information quality of each included resource.
Results. There was no statistically significant difference between average DISCERN scores for videos and webpage resources, and the majority were rated poor in quality.
Conclusions. The online resources for at home suture and staple removal are often not comprehensive and are below the standard quality for written information. Healthcare providers should consider referring their patients to validated online sources for suture removal to prevent misinformation and improve patient safety.

The Concept of Health Systems Science and Educational Needs in the Korean Context
Authors: Yang Eunbae B. , Lee Danbi , Lee Jong Tae
Published: October 2023

Physicians should be able to address health-related issues of patients and populations from a multidimensional perspective. Therefore, medical schools have a social responsibility to develop and implement curricula that enable trainees to acquire the competencies needed to improve all aspects of patient care and healthcare delivery. This study explored the concept of health systems science concept as the third pillar of medical education (the other two are basic science and clinical medicine) in the Korean context, as well as related educational needs. The theoretical foundation of health systems science is the biopsychosocial conceptual model, which emphasizes the biological, psychological, and social factors surrounding patients. We concluded that the three domains (core functional, foundational, linking) and 12 subcategories of health systems science proposed by the Association of American Medical Colleges could be applied to Korean medical education. Health systems science education must be emphasized to solve the various healthcare problems facing Korea today and to train physicians to provide medical services in line with society’s needs. Introducing a health systems science curriculum will be challenging in the Korean medical environment, which has traditionally emphasized basic science and clinical medical education. Health systems science education should begin in the basic medical education phase, where physicians’ professional identity is formed, and continue through graduate medical education. It is essential to understand related educational needs, develop curricular content, conduct faculty development programs, and provide financial resources for the development of an integrated curriculum.
The Impact of Student Engagement and Motivation in the Statistics Learning Process
Authors: Halomoan Lumbantoruan Jitu
Published: October 2023

The aim of the present exploratory study was to examine students’ situational engagement and motivation in the statistics classroom at Zayed University, in Dubai, United Arab Emirates (UAE). Two instruments were used for this purpose: a) experience sampling method (ESM), and b) the validated Mathematics Motivation Questionnaire (MMQ). This study employed two samples, at undergraduate level (2nd and 4th Semesters). Participants consisted of 100 students enrolled in Statistics I and Statistics II (Probability and Structure of Randomness). The results indicate that, apart from challenge and effort, emotional engagement is not significantly different across different activities. The results also indicate increases in intrinsic value and utility value and decreases in test anxiety. Finally, results indicate higher engagement and effort when social interaction is purposely planned and fostered, such as in small groups. On the contrary, individual class activities seem to generate slightly lower levels of engagement and effort. These findings have significant implications for educators and researchers who seek to enhance students' engagement and motivation in their statistics courses

Published: October 2023

Background: The coronavirus disease 2019 (COVID-19) pandemic, caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), is increasingly drawing worldwide attention. Among multiple risk factors, obesity is one of the factors that can influence the disease severity. This study aimed to explore the impact of obesity on the severity of COVID-19 infection.
Methods: This cross-sectional study was conducted in the Department of Respiratory Medicine, Bangabandhu Sheikh Mujib Medical University, Dhaka from September 2020 to February 2021. The Adult (Aged ≥18 years) patients of both genders, who were COVID-19 positive, were included in this study. Ninety-one COVID-19 patients with BMI≥25 kg/m2 were set as case and another ninety-one patients with BMI<25 kg/m2 were selected as control. The patient's BMI and waist circumference (WC) were recorded. Disease severity was evaluated by the management of COVID-19 disease guidelines by the World Health Organization (WHO) 2020.
Results: The maximum patients were male (65.38%), in the sixth and seventh decades. The proportion of severe illness was higher in the obese group 69.2% compared to the non-obese 47.3%. Patients with obesity require more ICU support (15.4% versus 5.5%) and invasive mechanical ventilation (9.9% versus 2.2%) compared to non-obese patients. In multivariate logistic regression analysis, after adjusting age, diabetes mellitus, and hypertension, obesity (BMI>25 kg/m2) was an independent risk factor for severe illness.
Conclusions: Obese patients are associated with severe COVID-19 pneumonia.  As BMI increases, disease severity increases, needs more ICU support, and needs more invasive mechanical ventilation.

Published: October 2023

Background: Genital herpes is caused predominantly by Herpes simplex virus type 2 (HSV-2) and less commonly by HSV-1. Genital HSV-1 infection results from oral sex, with fewer recurrences, mild symptoms, less asymptomatic shedding and poor genital transmission. The present study was undertaken to identify frequency of occurrence of HSV-1 and HSV-2 in genital herpes by microscopy, serology and Real Time Polymerase Chain Reaction (RT-PCR).
Methods: Genital ulcer swabs and serum were collected at regional STI centre, Govt Medical College and Hospital, Nagpur.  A total of 53 patients of Genital Ulcer Disease from December 2020 -22 were examined for etiology by microscopy, serum IgM and IgG against HSV-1 and 2 by ELISA and HSV-1 and 2 DNA by RT- PCR.
Results: Out of 53 genital swabs processed, 6 (11.3%) and 28 (52.8%) samples were positive for HSV-1 and 2 DNA respectively. Of the 6 HSV-1 DNA positive samples, seropositivity for HSV-1 IgM was in 2 (33.3%) samples and for HSV-1 IgG in 4 (66.7%) samples. Of the 28 HSV-2 DNA samples, HSV-2 IgM was positive in 4 (14.3%) samples and HSV-2 IgG was positive in 7 (25%) samples, multi nucleated giant cells were seen in 2 (7.14%) samples. The remaining 15 (53.6%) HSV-2 DNA positive samples were seronegative.
Conclusions: HSV-1 was detected in 6 (11.3%) samples. Though these genital ulcers may be mild, it is important to counsel the patients for abstinence or safe sex practices to prevent their partners from acquiring painful non-genital ulcers due to HSV-1.

Published: October 2023

Background: India has experienced an unprecedented heave of mucormycosis (MCR) cases during second wave of COVID-19. Possible mechanisms may involve immune and inflammatory processes. The aim of the study is to estimate the role of inflammatory markers for triaging patients of COVID-19 associated rhino-orbital-cerebral mucormycosis (CAROCM) at tertiary care hospital in north India.
Methods: A retrospective observational study was conducted between September 2021 to December 2021, at Government medical college and hospital, Patiala (Pb), 83 CAROCM patients admitted in ENT department were evaluated for serum ferritin, D-dimer and PCT.
Results: The median age of the patients was 50 years. The number of male patients were 45 and female patients were 38. Based upon the medical history and associated comorbidities involved, 83 CAROCM patients were divided into three groups. 43 diabetic patients in group I, 33 patients with multiple risk factors in group II and 7 patients with no comorbidity in group III. The mean D-dimer levels were 702 ng/ml in group 1, 831ng/ml in group II and 399 ng/ml in group III, and ferritin levels were 522 ng/ml, 711 ng/ml and 426 ng/ml in group I, II and III respectively. Mean PCT levels in group I were 0.27 ng/ml, 1.32 ng/ml in group II and 0.42 ng/ml in group III.
Conclusions: Our study concluded that a significant association was observed between levels of inflammatory markers and susceptibility factors. Serum ferritin, D-dimer and procalcitonin, can be used for assessing the severity of infection and decreases the mortality and morbidity in CAROCM patients.

Background: Ultrasound guided measurement of optic nerve sheath diameter (ONSD) is an emerging non invasive bedside tool that is being used to detect raised intracranial pressure (ICP) in patients with traumatic brain injury(TBI). Early detection of raised ICP can guide in the timely management of such patients with raised ICP due to TBI.
Methods: A prospective, observational, open labelled study planned with a 30 patients of TBI of both genders, aged between 18 to 70 years. ONSD readings were taken 3 times a day for three days from the time of admission with portable SonoSite ultrasound machine. Data was expressed as mean ±standard deviation. Values were compared using T test and P value was calculated.
Results: Highest reading recorded in patients with GCS <8 was 6.26±0.73 in comparison to 5.38±0.56 (p=0.001) in patients with GCS >8. Highest reading of ONSD  correlating  with a positive CT finding at admission was 6.22±.81 and was 5.46±.57 (p=0.006)  in patients with negative findings on CT. ROC curve with average cut off of 6 mm  correlated with positive CT findings with sensitivity of 80%, specificity of 70%  and negative predictive value of 87% was found.
Conclusions: Ultrasound-guided ONSD monitoring shows promise for diagnosing intracranial hypertension in traumatic brain injury. Correlations with CT, GCS, and outcomes emphasize its clinical relevance, warranting further validatio.

Authors: Khan Javid Ahmed , Ashraf Aadil , Fayaz Faizana , Qureshi Waseem
Published: October 2023

Background: Hypertensive disorders of pregnancy are a major cause of poor pregnancy outcome and complicate ~6-11% of all pregnancies. When diagnosed during pregnancy, hypertension disorders escalate the maternal risk of placental abruption, cerebrovascular accident and disseminated intravascular coagulation, as well as fetal risk of intrauterine growth restriction, intrauterine death and prematurity. Interpretation of the ECG is an important component in the assessment of cardiovascular adaptations during pregnancy.
Methods: In this study, 105 pregnant women (gestational age >20 weeks) with hypertensive disorders of pregnancy (HDP) in the range of 18 to 45 years of age were recruited and compared with the equal number of age matched normotensive pregnant women. ECG parameters were compared with those of normotensive pregnant women.
Results: There was left axis deviation in 28.6% in HDP group as compared to 10.5% in control group, while as 71.4% and 84.8% had normal axis in HDP and control group respectively, 4.85% in control group had right axis deviation there was statistical significant difference between the two (p<0.05). There was statistically significant difference between the two groups in ECG characteristics of T wave flattening or inversion in lead III, T wave in lead V1, V2 and V3, (p<0.05). The mean QTc interval was found to be 440.28±43.62 msec in HDP women and 417.42±21.74 msec in normotensive control pregnant women and there was statistically significant difference between the two groups (p=0.000).
Conclusions: ECG abnormalities seen in patients with hypertensive disorders of pregnancy (HDP) include left axis deviation, T wave abnormalities, an alteration of ventricular repolarization as evidenced by prolongation of ECG parameters, such as QTc.
Unsafe abortions: the plight of the womb
Authors: Kaur Harpreet , Nandrajog Anchal , Shivanna Nischitha , Kaur Sarvjeet

Abortion is a common health care intervention in women of reproductive age group. It is reported that 6 out of 10 unintended pregnancies and 3 out of 10 of all pregnancies end up in induced abortion. Developing countries bear the burden of 97% of unsafe abortion and they account for 5-13% of maternal mortality. We have attempted to present a case series on unsafe abortions dealt with in our facility. It was a prospective observational study conducted over patients admitted in the department of OBG, GGSMCH, Faridkot over a period of 14 months. The patients presenting with post abortal complications constituted the study population. Out of the total 100 patients, 40 patients gave history of unsafe abortion; of whom 18 patients with grade 4 sepsis were included in study. Laparotomy was done in 12 patients, out of which there were 3 uterine repair, 1 intestinal repair and only peritoneal washings in the rest. Despite best efforts 5 patients succumbed to the sequelae of sepsis. Unsafe abortions and maternal mortality has a downward trend over the years, but still is a substantial burden on the economy. Regulations that force women to travel to attain legal care and face waiting periods lead to loss of income and other financial costs, and can make abortion inaccessible to women of low socio economic status. Therefore, availability of trained personnel and subsidized comprehensive abortion care services at the community health care centre level is the need of the hour.
Collet Sicard syndrome secondary to granulomatosis with polyangiitis
Authors: Francisco Pineda Galindo Luis , Gòmez-Piña Juan Josè , Prado Alejandro Esteban , Hernández Adriana Elizabeth Vázquez , Gallegos Fernando Méndez
Published: October 2023

Granulomatosis with polyangiitis (GPA) is a systemic vasculitis that affects small to medium-sized blood vessels. Although uncommon, cranial nerve (CN) involvement can result in CN palsy. We present a clinical case of a female with collet Sicard syndrome (CSS), displaying left-sided CN IX, X, XI, and XII involvement, which we determined to be caused by GPA. Our patient met 7 points on the American College of Rheumatology 2018 (ACR) criteria for GPA with positive ANCA, bilateral mastoiditis, and decreased sensorineural hearing. Early identification of GPA is crucial due to systemic CN involvement, as it can lead to dysphonia, dysphagia, and other complications. Early treatment can improve the functional prognosis of patients, requiring intensive induction immunosuppression due to frequent bilateral progression and worse prognosis. Despite its infrequency, timely diagnosis is critical for better patient outcomes.

Published: October 2023

Background: Adolescent girls often lack adequate knowledge and comfort when accessing reproductive health care and information. A woman’s health at different stages in her life is interconnected, such that the state of her menstrual health at present can influence her reproductive, sexual, and maternal health in the future. Therefore, possessing adequate understanding and awareness regarding menstruation and recognizing the significance of seeking healthcare will help in managing menstruation hygienically and with dignity.
Methods: A school-based cross-sectional study was conducted in a tribal welfare residential school in a rural setting among female adolescent girls in classes 6th, 7th, 8th, 9th, 10th, during September 2022 for 10 days, with objectives to assess knowledge about menstruation and to determine the health-seeking behaviour for menstrual health among them.
Results: In our study of 73 adolescent tribal girls (mean age: 13.86±1.33), 73.9% had a high knowledge level about menstruation. Self-medication was reported by 26%, while only 9.6% consulted a doctor. Higher menstrual pain was linked to a 3.25 times higher likelihood of consulting a doctor and a 5.5 times higher likelihood of self-medication.
Conclusions: While a majority of tribal adolescent girls demonstrated a good level of knowledge regarding menstruation, only 9.6% of them sought medical consultation from a doctor. A comprehensive approach that combines health education, challenging cultural taboos, and improving access to healthcare services is necessary to promote better healthcare-seeking behaviour among adolescent girls regarding menstruation.
