Objective: The aim of this study was to identify the procedures adopted by Brazilian orthodontists in the following situations: extraction space closure, anchorage control in case of necessary anchorage for group A and frequency of skeletal anchorage use, especially in the upper jaw.
Methods: A questionnaire was sent to the e-mail address of all dentists registered in the Brazilian Federal Council of Dentistry.
Results: The results showed that most Brazilian orthodontists usually perform extraction space closure by means of sliding mechanics. The use of palatal bar, inclusion of second molars in the archwire and space closure performed in two phases are the most used techniques for anchorage control in the upper jaw. The skeletal anchorage is referenced by 36.5% of specialists as a routine practice for the upper arch anchorage.
Conclusions: There is a wide variety of procedures adopted by Brazilian orthodontists for orthodontic space closure and anchorage control.

Uncontrolled reentries of space objects create a collision risk with aircraft in flight. While the probability of a strike is low, the consequences could be catastrophic. Moreover, the risk is rising due to increases in both reentries and flights.

The purpose of this study was to quantitatively assess the alveolar bone support of teeth adjacent to the cleft site in individuals with nonsyndromic cleft lip and palate (CLP) who have undergone either orthodontic space closure or space opening for missing lateral incisors. A cross-sectional retrospective study. University orthodontic clinic serving individuals with CLP.

Background: Prone transpsoas lumbar interbody fusion (PTP) is a newer technique to treat various spinal disc pathologies. PTP is a variation of lateral lumbar interbody fusion (LLIF) that is performed with the patient prone rather than in the lateral decubitus position. This approach offers similar benefits of lateral spinal surgery, which include less blood loss, shorter hospital stay, and quicker recovery compared with traditional open spine surgery.

Background: During the COVID-19 pandemic, atypical respiratory syncytial virus (RSV) circulation patterns emerged, with the occurrence of RSV activity outside the typical winter season. This study investigates the impact of COVID-19 and associated non-pharmaceutical interventions (NPIs) on RSV seasonality.
Methods: The onset, offset and peak of RSV epidemics from 2018 to 2022 across 12 European countries were determined using the 3% positivity threshold method.

Purpose: Acute hand infections (AHIs) remain a challenge for hand surgeons and represent a condition for which clinical outcomes are considerably affected by social barriers. We previously described the looped Penrose drainage technique, where a drain is sutured to itself in a loop and the outflow tract of egress is maintained, thus obviating the need for large incisions, wound closure, or repeat packing, thereby reducing the follow-up burden. In the face of escalating numbers of socioeconomically vulnerable patients, especially in urban settings, we aimed to characterize the clinical features and outcomes of this technique in an urban population of patients with AHI.
