To overcome this challenge, a novel concept was recently published called "Barbell Technique." This technique has been used more commonly for horizontal bone augmentation.

Barbell Technique: A Novel Approach for Bidirectional Bone Augmentation: Clinical and Tomographic Study.

Horizontal bone augmentation is a common surgical procedure used in implant therapy to achieve adequate bone volume to permit dental implant placement. However, most current techniques are focused on unidirectional bone reconstruction (grafting only on the buccal side). This study was carried out to validate a new device that will permit bidirectional bone augmentation.

Children and adolescents continue to be exposed to early work in Brazil.

2 million children and adolescents between 11 and 19 years old have not yet finished basic education and had left school. The current Brazilian scenario reflects the reality in which these children and adolescents are inserted, without sufficient resources for the continuity of basic or elementary education, and often the parents' lack of income leads these young people to seek work, as can be seen in several capitals and inland cities: children selling food at traffic lights, bars, restaurants, and similar situations5. According to a study carried out by Abrinq Foundation (Fundação Abrinq), in the last quarter of 2021, there were about 2.

Horizontal Bone Augmentation With Autogenous and Collagenated Xenogeneic Bone Blocks: A Split-Mouth Prospective Clinical, Tomographic, and Histological Pilot Study.

The aim of this study was to compare the clinical, tomographic, and histological performance of collagenated xenogeneic bone blocks (CXBB) in horizontal bone augmentations for implant placement. Five patients with an absence of the 4 upper incisors and an HAC 3 horizontal bone defect, with a remaining of 3 to 5 mm, underwent a bone-grafting procedure with CXBB (test group [TG], n = 5) and autogenous graft (control group [CG], n = 5), with one type of graft used on the right side and other type on the left side. Changes in bone thickness and density (tomographic evaluation), levels of complications (clinically), and distribution pattern between mineralized and nonmineralized tissue (histomorphometrically) were analyzed.

Childhood leukemia: Brazilian reality in children under fifteen years.

Leukemia is among the most prevalent cancers in children and adolescents in Brazil, affecting about 75% of children's public, especially males. Therefore, the southeast region of Brazil has a higher prevalence of cases, in which from 2019 to 2022 there were 1710 leukemia cases. In addition, the average of general notifications had higher frequency in 2021 with 1761 diagnoses, with higher emphasis on the southeast region, presenting 495 cases this year.

Child malnutrition in Brazil: Public health issue that needs awareness.

In developing countries, child malnutrition is a serious public health problem. Brazil is a country that has several projects to combat hunger and malnutrition in early childhood, but 2021 was a year with the highest number of hospitalizations of children up to 60 months of life in the last 13 years. Factors such as social disparities and the Covid-19 pandemic contributed to this scenario.

Clinical and parasitological impact of short-term treatment using miltefosine and allopurinol monotherapy or combination therapy in canine visceral leishmaniasis.

Canine visceral leishmaniasis is an endemic zoonosis in Brazil. Dogs are the main hosts in urban environments. The treatment has gained popularity since the Brazilian government authorized miltefosine for canine treatment.

Stolen innocence: Dishonor and taint in times of war.

As soon as they are taken prisoner, children and adolescents in times of war are inserted into a spiral of cruelty that progresses to rape or other countless forms of physical and psychological torture using sex as a weapon. Were these children and adolescents war sex slaves? Oral sex and other sexual barbarities are part of spaces of abuse and humiliation. The damage to the personality structure of these children and adolescents is severe.

Vaccination for COVID-19 in children: Denialism or misinformation?

In the current pandemic scenario, vaccines for children have been scientifically approved; however, there is a challenge faced globally: parents' hesitation about vaccinating their children for COVID-19, which can hamper adherence to vaccine campaigns. This issue is due to the lack of information or access to fake news that affects the parents' power of judgment. The experience of the vaccine process with Pfizer's immunizer in several countries successfully reduced the number of hospitalized and prevented hundreds of child deaths from COVID-19.

Impact of COVID-19 and its variants on indigenous Brazilian children.

The indigenous population has suffered from the impacts caused by Covid-19 since the beginning of the pandemic. Especially children, who live in a reality of extreme poverty, low level of education and precarious health services close to their communities. Health professionals must look closely at indigenous children so that they can help them deal with the impact that the pandemic has brought with it.

"Between the cross and the sword": Brazilian children face an influenza epidemic while still dealing with the COVID-19 pandemic.

The Influenza activity remained at inter-seasonal levels; however, influenza A(H3N2) detections continue to increase in Brazil, Chile, Paraguay, and Uruguay. Most of the activity and rising trend of A(H3N2) detections are recorded in Brazil. A bulletin issued by the Oswaldo Cruz Foundation (Fiocruz) reported significant presence of the influenza A virus, both in children and in the adult population, among cases of SARS-Cov-2.

Horizontal Bone Reconstruction on sites with different amounts of native bone: a retrospective study.

The lack of guidelines for bone augmentation procedures might compromise decision making in implantology. The objective of this study was to perform a retrospective study to verify the outcomes of horizontal bone reconstruction in implant dentistry with different types of materials and amounts of native bone in the recipient bed to allow for a new guideline for horizontal bone reconstruction. One hundred preoperative CT scans were retrospectively evaluated and categorized in accordance to horizontal bone defects as presence (Group P) or absence (Group A) of cancellous bone in the recipient bed.

A Contrast-Based Computational Model of Surprise and Its Applications.

We review our work on a contrast-based computational model of surprise and its applications. The review is contextualized within related research from psychology, philosophy, and particularly artificial intelligence. Influenced by psychological theories of surprise, the model assumes that surprise-eliciting events initiate a series of cognitive processes that begin with the appraisal of the event as unexpected, continue with the interruption of ongoing activity and the focusing of attention on the unexpected event, and culminate in the analysis and evaluation of the event and the revision of beliefs.

The Cognitive Effects of Wearable Cameras in Mild Alzheimer Disease - An Experimental Study.

Background: Wearable cameras are a new type of intervention aimed at stimulating memory in Alzheimer's disease (AD). Such passive external memory aids have started to be considered as alternatives to both more active external aids (such as writing in diaries, journals, and timetables) and to internal cognitive strategies (such as spaced retrieval, errorless learning).

Objective: In order to understand the benefits of these innovative devices for memory compensation, the present experiment examined the effectiveness of two memory training strategies: SenseCam, a wearable camera, a passive external memory aid and a memory training programme (MEMO+) created from tasks known to stimulate memory, in comparison with a control condition, a personal written diary.
