Nitrogen dioxide (NO2 ) is one of the harmful pollutants in ambient air and predominantly occurs in urban areas. Vehicular emission is one of the major sources of NO2 pollution in urban areas and can impact human health to a larger extent. This re view examines the temporal variations in NO₂ concentrations in Delhi's atmosphere from 2020 to 2023 and its implications for ambient air quality. Over the past few years, NO₂ levels in Delhi have shown significant fluctuations due to numerous factors including seasonal changes, traffic patterns, industrial activities, and the impacts of lockdown during COVID -19 pandemic. The analysis of air quality data reveals a correlation between increased NO₂ concentrations and the deterioration of air quality, leading to increasing health risks. This review underscores the need for continuous monitoring and more stringent regulatory measures to manage NO₂ emissions, aiming to improve air quality and mitigate the associated health impacts in Delhi

Recently the UK Infected Blood Inquiry (IBI) headed by Sir Brian Langstaff, a distinguished judge, completed his extensive six year investigation into the circumstances that unnecessarily caused many avoidable infections with the viruses HIV and HCV. Being involved myself with HIV/AIDS research since 1983, I was invited by the Inquiry to testify in 2018. I then wrote and pub lished in two papers what I told the Inquiry [1, 2].

Hookworm infection is a major public health concern and is the major cause of anemia in pregnant women. e aim of this study was to assess the prevalence and risk factors of hookworm and anemia among pregnant women attending antenatal care at Dabat Primary Hospital and Debark General Hospital, northern Ethiopia. A cross-sectional hospital-based study in volving 384 pregnant women was conducted from March to June 2023. Stool samples were collected and analyzed for the presence of hookworm infection using wet-mount and formol-ether sedimentation techniques. A blood sample was also col lected and analyzed for the hemoglobin (Hb) level of pregnant women. List of Abbreviations: ANC: Antenatal care; AOR: Adjusted odds ratio; CI: Con dence interval; COR: Crude odds ratio; IPI: Intestinal parasitic infection; SPSS: Statistical package for social science; STH: Soil transmitted helmenth e overall prevalence of hookworm infections was 21.4%, and the prevalence of anemia in this study was 17.7%. e mean Hb value was 14.2 ± 0.07 g/dl, with a range of 7.3–19.6 (Hb) levels. Of the anemic pregnant women, 82.3%, 67.6%, and 7.4% had mild, moderate, and severe anemia, re spectively. e result of multivariate logistic regression analysis revealed that residence, monthly income, gestation period, being unable to wear shoes, and soil eating habits were signi cant predictors of hookworm infection. In addition to this, monthly income, gestation period, and being unable to wear shoes were signi cant predictors of anemia in pregnant wom en in the study area. A relatively high prevalence of hookworm infections and anemia was observed among pregnant wom en. erefore, the study showed that it needs high work to increase the nutritional requirements of pregnant women since they increase during pregnancy and to help them wear shoes during pregnancy. An integrated hookworm prevention and control program should be designed as an important intervention program for women in general and pregnant women who participated in the study area.

This paper reports a case of a 10-year-old patient who had their upper right central incisor avulsed due to trauma while en gaging in a sporting activity. A er 72 hours, the patient sought medical attention, revealing the absence of the tooth in the socket, pain, and swelling. e chosen treatment was delayed dental replantation with stabilization in the socket using a ex ible splint. Following maintenance, endodontic treatment was performed, with intracanal medication change a er 15 days, followed by clinical and radiographic follow-up. e conducted treatment allowed the tooth to remain in the oral cavity for 60 months without infections, albeit in the presence of progressive resorptive processes. is case report suggests that de layed replantation of a permanent incisor a er avulsion can be a bene cial treatment option for pediatric patients, preserv ing stomatognathic functions and the patient's quality of life until the possibility of de nitive rehabilitation
