Malocclusion: Prevalence and Determinants among Adolescents of Karachi, Pakistan.

OBJECTIVES: The aim of this study was to determine the prevalence of malocclusion and its associated demographic and clinical factors in young adolescents (13-15 years) of Karachi, Pakistan. MATERIALS AND METHODS: An epidemiological survey included 500 young adolescents of registered schools, madrassas (Islamic education system), and shop workers of Gulshan-e-Iqbal Town. It was a cross-sectional analytical study design. Multistage random sampling technique was used to enroll participants. The pattern of occlusion was recorded with other related features using Angle's classification. Health status was recorded through World Health Organization-guided indices (decayed, missing, and filled permanent teeth [DMFT], community periodontal index of treatment needs [CPITN], and body mass index [BMI]). The information, thus, obtained was analyzed through SPSS using the chi-squared test and regression models. RESULTS: Forty four percent of the participants were female, while overall estimated prevalence of malocclusion in young adolescents of Karachi was 57.4%. After adjustments, participants going to any kind of education system had less malocclusion in comparison to those who were not going to any education system (adjusted odds ratio [aOR] = 0.305, 95% confidence interval [CI] = 0.12-0.73); mother's education especially higher level (aOR = 2.02, 95% CI = 1.08-3.75) and presence of periodontal disease (aOR = 1.57, 95% CI = 1.06-2.33) were significantly associated with malocclusion. CONCLUSION: This study showed that the class I malocclusion is prevalent in the local community. Demographic factors like gender, age, self-reported ethnicity, and BMI did not show any significant role. Education or knowledge of parents and young adolescents does play an influential role in decreasing malocclusion. Young adolescents, who are more prone to oral health problems at an early age, would have more chances to develop occlusal discrepancies.

Common misconceptions regarding COVID-19 among health care professionals: an online global cross-sectional survey / Conceptos erróneos comunes sobre COVID-19 entre los profesionales de la salud: una encuesta transversal global en línea

Background: The COVID-19 pandemic has taken the world by storm, with cases continuously increasing by the hour and with a shortage of information regarding the virus available to the general public. Despite the availability of trusted online sources, there are still misconceptions relating to the virus floating around. This study aimed to find out the level of misconceptions among healthcare professionals (HCPs) worldwide about the ensuing COVID-19 pandemic. Materials and Methods: A descriptive cross sectional study was conducted through a global online survey. The self-administered questionnaire was designed and registered at an online website (Kwiksurveys). A total of 652 participants from 35 different countries across the world responded. Statistical analysis was performed using SPSS version 23. Socio-demographic and discipline characteristics were compared with the help of the chi-square test and univariate and multivariate logistic regression to find significant relationships. Results: Among all HCPs, general physicians (61.2%) were the most common respondents. The responses from females (63.3%) almost doubled those of men, and nearly half of the participants were working in private institutes (49.2%). Additionally, the major source of information used by HCPs about COVID-19 was social media (55.4%). Regarding misconception assessment, 71.6% of participants had correct concepts regarding COVID-19. However, 28.4% had incorrect information. Female HCPs were 1.49 times more likely to have correct concepts compared to males (OR=1.49, 95% CI=1.04-2.14). Conclusions: The majority of the HCPs were keeping themselves up-to-date with current information concerning the knowledge, prevention, and hygiene practices of COVID-19 infection. However, some misconceptions are deeply rooted in the mindsets of HCPs worldwide and need to be addressed by the continuous professional development of HCPs. The availability of reliable sources of information on the pandemic should be encouraged, with adequate explanations also available to the general public in simple terms.

Antecedentes: la pandemia de COVID-19 ha asolado al mundo, con casos que aumentan continuamente y con una escasez de información sobre el virus disponible para el público en general. A pesar de la disponibilidad de fuentes confiables en línea, todavía hay conceptos erróneos relacionados con el virus. Este estudio tuvo como objetivo dilucidar el nivel de ideas erróneas entre los profesionales de la salud (PS) en todo el mundo sobre la pandemia de COVID-19. Material y Métodos: Se realizó un estudio descriptivo de corte transversal a través de una encuesta global en línea. El cuestionario autoadministrado fue diseñado y registrado en un sitio web en línea (Kwiksurveys). Respondieron un total de 652 participantes de 35 países. El análisis estadístico se realizó con el programa SPSS versión 23. Las características sociodemográficas y disciplinarias se compararon con la ayuda de la prueba de chi-cuadrado y la regresión logística univariada y multivariada para encontrar relaciones significativas. Resultado: Entre todos los profesionales de la salud, los médicos generales (61,2%) fueron los que más respondieron. Las respuestas de las mujeres (63,3%) casi duplicaron las de los hombres, y casi la mitad de los participantes trabajaban en institutos privados (49,2%). Además, la principal fuente de información utilizada por los profesionales de la salud sobre COVID-19 fueron las redes sociales (55,4%). En cuanto a los conceptos erróneos, el 71,6% de los participantes tenían conceptos correctos con respecto a COVID-19. Sin embargo, el 28.4% poseía información incorrecta. Los profesionales de la salud mujeres tenían 1.49 veces más probabilidades de tener conceptos correctos en comparación con los hombres (OR = 1.49, IC 95% = 1.04 2.14). conclusión: La mayoría de los profesionales de la salud se mantuvieron actualizados con la información actual sobre el conocimiento, la prevención y las prácticas de higiene de la infección por COVID-19. Sin embargo, algunos conceptos erróneos están profundamente arraigados en la mentalidad de los PS en todo el mundo y deben abordarse mediante el continuo desarrollo profesional de los PS. Se debe alentar la disponibilidad de fuentes confiables de información sobre la pandemia, con explicaciones adecuadas también disponibles para el público en general en términos simples.

Dynamic relationship among economic growth, energy, trade openness, tourism, and environmental degradation: fresh global evidence.

This study analyzes the impact of economic growth, energy consumption, trade openness, and tourism on environmental degradation measured by CO2 emissions by using annual data of 112 countries for the period 1995 to 2017. Furthermore, the study also analyzes the relationship of the variables as mentioned above in four income and five regional groups of the world. The findings confirm the existence of environmental Kuznets curve (EKC), and level of income (turning point) is also determined, which helps in the improvement of the environmental quality of selected sample countries. The results of the overall sample show that economic growth, use of energy, and tourism are proved to be harmful to the environment, whereas the result of trade openness is not statistically robust. Results of sub-samples are mixed. Findings of this study highlight some essential steps which must be taken by the government and international environmental agencies for the protection of the environment through efficient utilization of energy and sustainable tourism.
