Introduction: Adolescent idiopathic scoliosis (AIS) affects an estimated 200 million adolescents globally and curvatures exceeding 30° at skeletal maturity are associated with increased health risks in adulthood. The International Society for the Orthopedic and Rehabilitative Treatment of Scoliosis recommends specific therapeutic exercises to prevent the progression of AIS. However, studies have questioned the effects of specific and general therapeutic exercises on the progression of AIS.

The inclusion criteria were based on the PCC strategy (participants, concept, and context), as follows: population (adults and older adults), concept (ultrasound assessment), and context (swallowing assessment). The review included observational, experimental, descriptive, and analytical studies and excluded those that were not available in full, animal studies, in vitro studies, letters to the editor, errata, study protocols, and those that used ultrasound for purposes other than swallowing.

Methods: A forward-backward translation process was employed to produce a Brazilian Portuguese version of the Brace Questionnaire, followed by comprehensive cross-cultural adaptation stages. The measurements of internal consistency and test-retest reliability were assessed by Cronbach's a and intraclass correlation coefficient (ICC), respectively.
Objective: To evaluate smartphone addiction and postural alterations in the cervical region in adolescents.
Methods: A cross-sectional study with 281 adolescents (15 to 19 years old), attending the 1st to the 3rd grades of High School, carried out between September and October 2019 in the city of Fortaleza, Ceará, Brazil. Data collection took place in two stages.

Neonates have an immature immune system, which increases their vulnerability to infectious agents and inflammatory insults. The administration of the immunostimulatory agent lipopolysaccharide (LPS) has been shown to induce the expression of pro-inflammatory cytokines and cause behavior alterations in rodents at different ages. However, the effects of LPS administration during the neonatal period and its consequences during immune system maturation remain to be elucidated.

Methods: Observational study developed between October 2017 and June 2018 with a sample of 20 newborns and infants who attended a dental clinic and were diagnosed with ankyloglossia. Another 20 were excluded for meeting some of the following exclusion criteria: babies more than 6 months old, who were not on exclusive or mixed breastfeeding, who had other clinical impairments that interfered with breastfeeding, who had other foods introduced into their diet, who had neurological changes and/or craniofacial deformities, and/or who did not finish all the stages of the study.
Introduction: The field of workers' health within the scope of the Brazilian Unified Health System needs to revitalize its space in terms of coordinating care in primary health care based on social determinants of health.
Objectives: To contextualize and describe the health-related situational diagnosis of primary care workers from the metropolitan region of Fortaleza, state of Ceará, Brazil.
Methods: This was a descriptive, quantitative, and exploratory study conducted at a primary care unit in the metropolitan region of Fortaleza, Ceará, from January to March 2019.
The iboga alkaloids are promising antiaddictive and neuroregeneration candidates for medical treatment. There is a lack of studies for C20-epi iboga alkaloids due to the synthetic difficulties. Herein we report the shortest total synthesis of (+)-epiibogamine in seven steps from trimethyl orthobutyrate.

Background: Total hip arthroplasty (THA) is a widely used surgical procedure to reduce pain and improve function and quality of life in patients with hip disorders. The most common condition that leads to THA is osteoarthritis, with most surgeries being performed to treat severe osteoarthritis with pain and functional limitations. Despite the evident success of THA, the search for its improvement and better results, especially in the long term, continues, especially in older patients, for which there is still little scientific evidence.

The lack of knowledge by health professionals in the management of scoliosis can lead to an erroneous diagnosis. The aim of the current study was to understand the influence of length of professional experience on the knowledge of Brazilian physical therapists regarding international guidelines for the treatment of adolescent idiopathic scoliosis. The study was conducted using an online questionnaire consisting of 23 questions, divided into 8 questions on sociodemographic data and 15 questions based on information provided by the guidelines in the SOSORT 2016.

Here, we report the structure revision of nordine based on incongruities found for carbon chemical shifts in the originally proposed structure, in addition to formation of a diacetylated derivative. As expected, a single-crystal X-ray diffraction analysis unambiguously confirmed our proposal that the nordine () structure contains an ether-bridged bicyclic ring between C-10 and C-7 and hydroxy groups at C-2 and C-6.

Dramatic changes in diastereoselectivity and stereoselectivity were observed by choice of metal bases. The mechanistic understanding for the switch in diastereoselectivity was assisted by DFT computational modeling, which suggests the facial approach is governed by aza-enolate geometry.

Cytochrome P450 monooxygenase enzymes found in nature carry out a wide range of difficult chemical reactions, such as the oxidation of the monoterpene indole alkaloid (-)-tabersonine at the unreactive 16th position on the indoline benzene ring in the biosynthesis of biologically active natural products such as the bis-indole alkaloid (-)-melodinine K. Herein, we describe the first semisynthesis of (-)-melodinine K enabled by a biological gram scale route to the northern fragment, (-)-16-hydroxytabersonine, as well as a chemical route to the southern fragment, (-)-pachysiphine, both derived from (-)-tabersonine and subsequently coupled in only eight linear steps.

This panel of complex compounds enabled the exploration of indole modifications to optimize the indole alkaloids' anticancer activity, generating lead compounds (, with C15-hydroxy, C16-methoxy, and/or C17-methoxy derivatizations) that potently inhibit cancer cell line growth in the single-digit micromolar range. These results can help guide the development of terpenoid alkaloid therapeutics.

The superior biological activity of solithromycin against streptococci and other bacteria causative of community-acquired pneumonia pathogens, compared to telithromycin and other macrolides encouraged us to extensively explore this class of antibiotics. We, thus, present the design and synthesis of a novel series of solithromycin analogs.

This displacement measure has been analyzed with ultrasound images because this method does not expose the patient to radiation, has a good cost-benefit ratio, and is safe for the patient. However, there is no consensus on the reliability of this ultrasound measure.
