ABSTRACT
BACKGROUND: Adolescents are more prone to depression, which needs early identification. AIM: The aim of the study is to assess the prevalence of depression in school-going adolescents and its association with their scholastic performance. MATERIALS AND METHODS: This questionnaire-based cross-sectional study was conducted on 473 students, among whom 271 girls and 202 boys with an age group of 12-17 years, who were selected through simple random sampling from four high schools located in and around Kolar city, Karnataka, India, from January 2023 to March 2023, were included in the study after obtaining three informed consents from adolescents. A questionnaire was given to all the study participants, and the depression was assessed according to the Centre for Epidemiological Studies Depression Scale for Children (CES-DC) score. The severity of depression among the children was assessed by the Patient Health Questionnaire-A (PHQ-A). Further, these children were assessed for their scholastic performance based on their final examination scores. The data were entered into an Excel sheet, and statistical analysis was performed. RESULTS: A total of 473 subjects were included in the present study; 177 had depression, which represents 37% of the total population. According to PHQ-A, 31% had mild depression, 5% had moderate depression, and 1% had severe depression. The association between depression and scholastic performance was not significant. CONCLUSION: In the current study sample, depression was found to be mild to moderate, which reflects the overall performance of adolescents. All students were treated accordingly. Hence, active measures are to be initiated to prevent depression.
ABSTRACT
AIM: Most dental procedures are aerosol-generating and hence highly risky for spreading SARS-CoV-2 (COVID-19) infection. This can lead to sufficient psychological distress, avoidance of risky procedures, and impact on dental practice. We intend to examine the effect of the COVID-19 pandemic on dental practice and psychological distress among dental practitioners. METHODS: An online survey was conducted by an email-based survey link; 1257 registered dental practitioners were contacted across the country. RESULTS: Most dental practitioners continue to practice during the COVID-19 pandemic (81.08%). Postgraduate specialists significantly outnumber undergraduates in performing dental procedures (p=.001). Career-related anxiety was considerably high among postgraduates (61.96%; p=.036) during the initial phase of the SARS-CoV-2 pandemic in India. In contrast, self-efficacy was significantly better among postgraduates than undergraduates (p=.027). CONCLUSION: Dental practitioners suffered considerable impact due to the COVID-19 pandemic. It is important to enhance coping and self-efficacy strategies among dental practitioners.
ABSTRACT
Infection of the pebrine disease has been found to be highly virulent and harm the cocoon yield as well as characters of silkworm Anthereae mylitta. Therefore, an attempt was made to evaluate the impact of parasite Nosema species on the ecorace (Sukinda) of A. mylitta in respect of transovarial transmitted (T1), secondary infection (T2) and healthy silkworm (T3). In comparison to T3, the number of larval mortality was 16 and 11 in T1 and T2 respectively; whereas as number of pupal mortality was 6 and 5 in T1 and T2 respectivelyThe larval weight, number of moths emerged, number of eggs laid and percent hatchability were reduced in T1 and T2 in comparison to T3.The infected layings were high in T1 (51%) and T2 (42%) as against T3 (0%). Similarly, the infected moths were 34% in T1 and 15% in T2 as against 0 percent in T3. All the characteristics parameters of cocoon were reduced in T1 and T2 against T3. The study explains that there was no significant variation between T1 and T2 on different parameters of larva, pupa and cocoon characters.

The tasar silkworm, Antheraea mylitta Drury, Andhra local ecorace is an exclusive race of Andhra Pradesh. It is on the verge of extinction due to difficulty of acclimatisation at breeding and rearing stages. As an attempt to protect this race, a method of total indoor rearing has been done. In this context, the estimation of free amino acids, excretory products- urea and uric acid were compared during the fourth and fifth instars of tasar silkworm, reared under outdoor and indoor conditions. The study has revealed that amino acids decreased in the fat body in outdoor and indoor reared larvae in contrast to that in the haemolymph where it has gradually increased from first to third crops. This is an important finding as it reveals that indoor worms seem to adopt proteolytic activity in the haemolymph. Secondly, in the fifth instar the excretory products are more compared to fourth instar in the indoor reared worms. During fifth instar, formation of nitrogenous products lessens as silk synthesis enhances. The present study reveals that decrease in uric acid in fifth instar implies increase in growth rate and silk synthesis in both outdoor and indoor worms. The findings of the present investigation is helpful in the conservation and protection of the A. mylitta, Andhra local ecorace.
