Determinants of delayed healthcare access and stigma associated with pandemic SARS-CoV-2 infec-tion: findings from a pilot study in the immigrant population in Catania (Sicily Region, Southern Italy).

Background: the Coronavirus disease 2019 (COVID-19) pandemic may have aggravated existing social and healthcare inequalities among particular population groups, such as ethnic minorities, who showed increased susceptibility to SARS-CoV-2 infection.

Objectives: to characterize risk profiles or determinants of delayed healthcare access, as well as knowledge, risk perception, behaviour, and social stigma concerning SARS-CoV-2 infection in the immigrant population in the city of Catania (Sicily Region, Southern Italy).

Design: pilot, descriptive study.

[Reducing the impact of COVID-19 in immigrants: a systematic review of the efficacy of interventions].

Background: the spread of SARS-CoV-2 in the population has amplified the effects of health inequalities, particularly in the most vulnerable groups such as immigrants and refugees. An assessment of the intervention to contain the COVID-19 in these population groups was essential to define new strategies for more equitable, inclusive, and effective health policies to on health.

Objectives: to provide a systematic synopsis of the impact of interventions to contain the spread of SARS-CoV-2 in immigrants.

[Impact of COVID-19 on foreign population resident in urban areas of Italy: selection of indicators, data sources, and definition of geographical stratification levels].

Objectives: to describe indicators, data sources, and levels of geographical stratification used within the framework of the CCM project "Epidemiological Surveillance and Control of COVID-19 in Metropolitan Urban Areas and for the containment of SARS-CoV-2 circulation in the immigrant population in Italy".

Design: population-based observational study based on data from the Integrated Covid-19 Surveillance System and the archive of hospital discharge records.

Setting And Participants: interregional collaborative project.

[Cryptorchidism: An update of advances in its diagnosis and treatment].

The absence of one or both testicles in the scrotal position is defined as cryptorchidism. It occurs in 1 - 8 % of full-term newborns and up to 45 % of preterm newborns. Its detection is of great importance due to its association with fertility disorders and the risk of malignancy.

Surgically assisted rapid maxillary expansion: current concepts of minimally invasive approaches.

Studies have consistently shown an association of the Le Fort I osteotomy with undesirable adverse events in the nasolabial region, including lengthening and thinning of the upper lip, a reduction in upper vermilion exposure, and nasal base enlargement. Various minimally invasive techniques have been developed based on knowledge collected over recent decades on the aetiopathogenesis of these aesthetic impairments. The common scope of these techniques is to reduce the damage to the facial soft tissues and achieve a sound and spontaneous healing process, avoiding those procedures that are commonly used to counteract undesirable aesthetic changes.
