Relation of Vitamin D levels with positive and negative symptoms of schizophrenia – A hospital based cross-sectional comparative study
Authors: Ghosh Soumitra , Deka Bikashita 
Published: September 2023

ABSTRACT

Background:
The association between altered serum Vitamin D levels and schizophrenia has been an area that has evoked a recent fervor. The neurohumoral and neuro immunomodulatory functions of Vitamin D might have a role to play in understanding the causation of the disease and thus appear promising in the diagnostic and therapeutic frontiers of the disease.

Aims and Objectives:
We aimed to estimate and compare serum Vitamin D levels in drug-free cases of schizophrenia and in healthy control groups. The comparison was also made among the subgroups of positive and negative schizophrenia.

Materials and Methods:
The study, a hospital-based cross-sectional comparative study was carried out in the Department of Psychiatry, in a hospital in Assam over a period of 1 year. Fifty drug-free subjects of schizophrenia (Group A) diagnosed and confirmed according to International Classification of Diseases 10 were selected by consecutive sampling and 50 age and sex frequency-matched subjects (Group B) were selected from the healthy population. The cases (Group A) were divided into positive and negative groups (Group A1 and A2) based on the composite scoring of the Positive and Negative Syndrome Scale. After approval from the institutional ethics committee and obtaining written informed consent, Vitamin D levels were assessed in both groups of cases and controls and comparison was made.

Results:
After statistical analysis, it was seen that males were more in proportion and mostly in the age group of 20-39 years. The median Vitamin D level among the cases was 12.45 ng/mL and that among controls was 20.03 ng/mL which was statistically significant (P value .00932). Among the positive and negative schizophrenia subgroup, there was no statistically significant difference in Vitamin D levels at means of 16.54 ng/mL and 16.25 ng/Ml, respectively. The variation in Vitamin D levels in schizophrenics and the healthy population is thus discernible.

Conclusion:
It can be said that serum Vitamin D levels were significantly low in people with schizophrenia compared to the general population. Furthermore, it is seen that mean Vitamin D status is similar in both the groups of positive and negative schizophrenia negating the possibility of alteration of Vitamin D levels depending on the differences in symptomatology or in pathophysiology of the two groups.

ABSTRACT
We estimated prevalence and severity of substance use in college students from three cities in North India and explored demographic correlates of substance use. This was a cross-sectional online survey. We used Alcohol, Smoking, and Substance Involvement Screening Test (ASSIST). We contacted respondents through social groups. We performed analyses from the original sample, bootstrapped samples, and random subsamples. A total of 229 (58.3%) respondents reported any lifetime substance use. A third of substance-using respondents were female. Alcohol (54.7%), tobacco (40.2%), and cannabis (15%) use were most commonly reported. Prevalence estimates did not differ between original and subsample analyses. A significant proportion of respondents (alcohol 29.7% and amphetamines 66.7%) were at moderate risk level. Male gender, family history of substance use, and commerce stream correlated with substance use. There were positive correlations between tobacco and alcohol and licit and illicit substance use. The study highlights the need for a comprehensive college substance misuse prevention policy.

ABSTRACT

Introduction:
Mental health at the workplace (WMH) is an important indicator for the optimum functioning of a medical institute. To establish an effective WMH, it is essential to understand the level of awareness, perceptions, and felt needs of students and staff of a medical institute regarding mental health services within the campus.

Material and Methods:
A cross-sectional web-based survey was conducted in an institution of national importance in Central India using a semistructured questionnaire based on Kobo Toolbox. Felt need for periodic mental health screening within the institutional campus (FN-S) and felt need of having a separate cell for mental healthcare of students and employees (FN-C) were analyzed using univariable and multivariable logistic regression.

Results:
A total of 526 out of 2190 eligible students and staff completed the survey (response rate 24.1%). About half of the participants were not aware, of whom to contact on campus in case of mental health concerns (MHCs), more than three-fourths were not aware of the rights for seeking treatment, and three-fourths thought that getting diagnosed with an MHC would negatively impact their academic course or work. There was a high felt need for mental health screening services (91.1%), and almost two-thirds felt the need for a separate mental health cell. The FN-S was higher among those from rural areas, those not using social media, those without a preexisting MHC, and those without FN-C. FN-C was higher in those not using social media, those having sleep disturbances, those with unawareness of the rights of a mentally ill person, those without any MHC, and those not having FN-S.

Conclusion:
Active efforts are needed to roll out a mental health screening policy and separate mental health cells within the medical institute. Future research should focus on a qualitative inquiry into the details of the above findings.
A model for competency-based training of undergraduate medical students to perform screening and brief intervention in alcohol use disorder—Findings from a study in a medical college in Delhi
Authors: Bhattacharyya Debajyoti , Timothy Anurag 
Published: September 2023

Background:
Alcohol use disorder (AUD) is a major cause of prolonged disability and an economic burden on communities across the world. The undergraduate (UG) curriculum in medical school in India does not allow adequate time to a structured learning about alcohol use disorder, its treatment, and prevention. The screening and brief intervention module (SBI) developed by the World Health Organisation (WHO) is an effective way to reduce drinking among risky drinkers. Training of undergraduates in SBI may go a long way in early intervention among problem drinkers. Hence, there is a felt need to incorporated the module in the clinical training schedule to enhance SBI skills among UGs to provide appropriate intervention at the primary healthcare level.

Methodology:
50 final year UG students of a medical college in Delhi were exposed to a competency-based training in alcohol SBI comprised of lectures, focused group discussions (FGD), and role-play during their 2-week clinical posting in psychiatry along with a hands-on training under supervision of faculty. Subsequently, they were assessed for knowledge and skills gained through objective-structured clinical examination (OSCE) and feedback taken from students about changes in their knowledge and attitudes towards alcohol use disorder SBI.

Results:
Pre- and post-self-reported outcome variables revealed significant positive impact (p < 0.001) of SBI module on competency of students in implementing SBI on patients. Assessment of knowledge on OSCE revealed mean scores of 9.48 ± 1.20 on 10 MCQs (of 01 mark each) with 47 students scoring 80% or above. On integrated OSCE assessment of competencies, 94% students made satisfactory demonstration at a desired level. Attendance in lectures and supervised SBI, attitudes pre- and post-intervention and confidence level post-intervention were found to be predictors of a high MCQ score. All faculty agreed about the feasibility of implementing competency-based SBI in existing clinical posting schedule.

Conclusion:
The study has demonstrated the feasibility of teaching competency-based alcohol SBI to undergraduate medical students in existing clinical posting curriculum in psychiatry and its efficacy in having a positive impact on the perception and approach of the students towards patients with alcohol use disorder.

Published: September 2023

Background:
This in vitro study investigated the time-dependent bactericidal effects of cold atmospheric argon plasma treatment of periodontal hand scalers as well as the scanning electron microscopic view of the scaler tip surfaces before and after plasma treatment.

Materials and Methods:
The study used 34 periodontal hand scalers which were divided into test and control groups. The scaler tips were inoculated with Escherichia coli and Staphylococcus aureus bacteria, following which the scalers in the control and test groups were subjected to conventional sterilization and argon plasma sterilization, respectively. Varying exposure times of plasma treatment were done on the test group samples to evaluate the minimum time required for complete sterilization. Subsequently, streaks were made on plate count agar using each of these instruments. The agar plates were then kept in an incubator for 24 h, following which bacterial colony count was assessed (colony-forming units/mL). Furthermore, the scanning electron microscopic (SEM) view of the scaler tip was studied before and after plasma treatment.

Results:
A complete elimination of bacterial load (Gram-positive as well as Gram-negative) from the instrument surface was achieved by the plasma exposure time of 15–20 s. SEM analysis did not show a significant difference before and after plasma treatment as not many organic residues were present on the scaler tip.

Conclusion:
Cold atmospheric pressure plasma is an efficient and time-saving method of sterilization, capable of destroying both Gram-positive and Gram-negative bacteria.
Three-dimensional-printed scaffolds for periodontal regeneration: A systematic review
Authors: Figueiredo Tarsila De Moura , Do Amaral Guilherme Castro Lima Silva , Bezerra Gabriela Neiva , Nakao Lais Yumi Souza , Villar Cristina Cunha 
Published: September 2023

Background:
As current ethical codes preclude determining whether the clinical improvements obtained with the use of three-dimensional (3D)-printed scaffolds represent true periodontal regeneration, the histological proof of evidence for regeneration must be demonstrated in animal models. Thus, this systematic review investigated the regenerative potential of 3D-printed scaffolds in animal models of periodontal defects.

Materials and Methods:
A systematic search was performed in four databases (Medline, Embase, Web of Science, and Scopus) to identify preclinical controlled studies that investigated the use of 3D-printed scaffolds for periodontal regeneration. Studies limited to periodontal defects treated with 3D scaffolds were eligible for inclusion. The primary outcome was periodontal regeneration, assessed histologically as new bone, cementum, and periodontal ligament (PDL). This systematic review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Quality was assessed according to the SRYCLE score.

Results:
Six studies met the inclusion criteria. Scaffolds were designed using computer-aided design software. While the absence of a scaffold resulted in defects repaired mainly with fibrous connective tissue, the use of nonguiding 3D scaffolds promoted some bone formation. Notably, the regeneration of cementum and functional PDL fibers perpendicularly inserted into the root surface and the alveolar bone was limited to the defects treated with multi-compartment fiber-guiding or ion-containing 3D scaffolds. Nevertheless, the quality of the evidence was limited due to the unclear risk of bias.

Conclusions:
Despite the limitations of the available evidence, the current data suggest that the use of printed multi-compartment fiber-guiding or ion-containing 3D scaffolds improves periodontal regeneration in animal models.
A clinical investigation to assess the regenerative potential of Biostite® (hydroxyapatite, type-I collagen and chondroitin-sulphate) with or without Paroguide® type-I collagen and chondroitin sulphate) membrane in the treatment of periodontal intrabony defects appraised with surgical re-entry and computer-assisted densitometric image analysis

Published: September 2023

Background:
The traditional treatment procedures which aimed at treating periodontal disease did not result in true periodontal regeneration. Unpredictability about osseous defect fill after periodontal flap surgery has stemmed in the research of a variety of regenerative materials. This randomized clinical trial was conducted to compare regenerative potential of Biostite® bone graft material with and without Paroguide® a bioresorbable membrane in the treatment of periodontal osseous defects.

Materials and Methods:
Twenty sites from a total of from ten patients were chosen for the study. Those sites were divided into experimental site A (Biostite®) and experimental site B (Biostite® with Paroguide®) at random. Plaque index and gingival index (GI) were the clinical parameters noted at baseline, 3rd, 6th and 9th months, whereas the probing pocket depth, clinical attachment level and gingival recession were noted at baseline, 6th and 9th months. Radiographic evaluation was made by using computer-assisted densitometric analysis. Intrasurgical measurements were done at baseline and 9 months. Statistical analysis was done using paired t-test and un-paired t-test.

Results:
Both experimental site A and B showed a significant reduction in plaque and GI. All clinical parameters as well as radiographic image analysis showed highly significant improvement from baseline to 9 months for both sites. Inter-group comparison does not show statistically significant improvement.

Conclusion:
The results of this study suggested that both Biostite® bone graft and Paroguide® membrane have promised encouraging results in the management of periodontal intrabony defects, however, the groups did differed to each other statistically.
PERBAIKAN INTERFERENSI GELOMBANG RF ANTARA VHF APP DAN VHF ER MENGGUNAKAN CAVITY FILTER (STUDI KASUS BANDARA SULTAN SYARIF KASIM II PEKAN BARU)
Authors: Sitopu Mutiara Widasari , Indra Cahyadi Catra 
Published: September 2023

This study describes the improvement of radio frequency VHF APP and VHF ER caused by bandwidth widening. VHF is the frequency used to transmit data that is transmitted in all directions. VHF A/G is an equipment used for communication between air traffic control (ATC) and pilot with a frequrncy range of 117.9 MHz – 137 MHz. To overcome the widening of the bandwidth, re-setting is done by using a cavity filter with a resonant frequency of 132.3 MHz and passing frequencies above the cut-off frequency. With the re –setting using a cavity filter, the bandwidth can be narrowed again so as to eliminate interference between VHF APP radios and VHF ER, but as a result the transmit power distance on VHF is reduced but does not reduce the performance of the radio.

Keywords: interference; cavity filter

Deputations of the Kazakh Ruling Elite to the Court of the Russian Emperors (mid – second half of the 19th century)
Authors: Gundova Olga E. 
Published: September 2023

The article explores the history of Kazakh deputations to the Russian imperial court in the mid-to-late 19th century. For the first time in historiography, we have analyzed the deputative missions of the Kazakhs during this period as a mechanism for interaction between the imperial ruling circles and the steppe elite. The article aims to scrutinize the goals and objectives of sending deputations, the composition of participants, and the characteristics of this practice throughout its existence.
Amidst the social transformation of Kazakh society – spurred by the integration of the steppe region into the broader imperial space – the status of the local elite began to be determined more by personal merits to the empire than by class origin. The Russian authorities viewed the practice of deputations as a means of bolstering the loyalty of the steppe aristocracy, and also to draw them in as participants in the empire’s civilizing mission in the East.
For the Kazakh elite, this practice provided an opportunity to solidify the authority among their peers, served as recognition of their merits at the highest level, and offered a path to integrate into the pan-Russian administrative class. Over the period in question, the number of petitions submitted by representatives of the Kazakh elite has consistently dwindled. By the end of the 19th century, the practice of deputations had ultimately degenerated and began to assume a mostly symbolic role.
This article is intended for specialists studying the policy of the Russian Empire in Kazakhstan.
Films “of Eastern Life” of the 1920s in the Light of Intercultural Communication among the Peoples of the USSR
Authors: Dianova Elena V. 
Published: September 2023

The article explores various films “about Eastern life” of the 1920s, conducting a historical and anthropological analysis of the content of these films and their reviews from the perspective of intercultural communication. The research methodology is grounded in the semiotic tradition and the communicative model proposed by Yu. M. Lotman. Printed media texts and visual sources (films) were used in the composition of this article. The aim of this piece is to expose the communicative functions of cinematography as a medium for information exchange and to ascertain the cognitive possibilities of silent cinema for the communicative interaction of the peoples of our country.
Films “from Eastern life” had to conform to certain criteria, taking into account the idiosyncrasies of the national mentality of the inhabitants of the eastern outskirts. The study revealed that legends were employed in scriptwriting as a phenomenon of folk spiritual culture. Films inspired by folklore depict architectural masterpieces and the diverse nature of different regions. The harem theme popular in Western Europe found its way into Soviet films “about Eastern life”, but the quest for the “false exotic of the East” often resulted in communication breakdowns. The “inauthentic” portrayal of the East did not resonate with viewers and film critics.
Nevertheless, silent films of the 1920s introduced the ethno-confessional characteristics of peoples, their history, traditional way of life, mores, and customs. These films contributed to the broadening of the national worldview, thereby confirming the high cognitive potential and significance of cinema in the intercultural communication within the multi-ethnic landscape of the USSR.

¿Existe un umbral glucémico para las complicaciones microvasculares?
Authors: Commendatore Víctor 
Published: September 2023

En un editorial de la Revista de la Sociedad Argentina de Diabetes, en 1997, el Dr. Juan José Gagliardino nos decía que “los nuevos valores para el diagnóstico de la diabetes mellitus (DM) buscan una mejor correlación con la aparición de lesiones microangiopáticas en retina”1, planteando la existencia de un umbral por encima del cual la retinopatía diabética (RD) aumentaba substancialmente su frecuencia, haciendo referencia al nuevo valor de la glucemia en ayunas (GA) para el diagnóstico de DM de 126 mg/dL, anunciado por el Comité Internacional de Expertos convocados por la American Diabetes Association (ADA) que reevaluó la clasificación y los criterios de diagnóstico establecidos por el National Diabetes Data Group en 19792,3.
Pero, ¿existe realmente un umbral? Los valores de corte actuales para el diagnóstico de DM de la GA, la glucemia poscarga (GPC) y la HbA1c, ¿descartan que un paciente con 122 mg/dL en ayunas y 189 mg/dL a los 120 minutos o una HbA1c de 6,0% pueda desarrollar lesiones microangiopáticas?
Un subestudio del Diabetes Prevention Program (National DPP) menciona que el examen más cuidadoso de la glucemia a largo plazo en esta cohorte y la documentación de la RD durante la prediabetes respaldan la idea de que la retinopatía puede ocurrir en un continuo más amplio de glucemia que el que abarcan los criterios diagnósticos actuales, planteando que estos parámetros, basados en el riesgo asociado de RD, deberían reconsiderarse4.
Existen numerosos estudios en los que aparecen complicaciones microvasculares durante la prediabetes, por lo cual la idea de un umbral debería cuestionarse severamente5,6,7.
