This study evaluated IL‐6 salivary levels as well as the +3954 polymorphism of IL‐1β in patients with burning mouth syndrome and healthy individuals, through case‐control studies. This systematic review and meta‐analysis followed the Preferred Reporting Items for Systematic Reviews and Meta‐Analyses guidelines. We conducted this research in PubMed/MEDLINE, Cochrane Library and Web of Science databases. The risk of bias was measured based in the Newcastle‐Ottawa Scale. Researches with a group of patients with burning mouth syndrome and a control group in which the presence of the +3954 polymorphism of IL‐1β and/ or IL‐6 salivary levels through non‐stimulated saliva were evaluated to detect if this interleukin concentrations are increased in patients and if the polymorphism is a risk factor for this syndrome. We identified seven studies with total of 440 participants, 229 patients with burning mouth syndrome and 211 healthy controls, ages 24‐84 years old. The female gender was predominant. Patients in the majority of studies did not present increased levels of IL‐6 and the +3954 polymorphism of IL‐1β is not a risk factor for this syndrome. A few studies researched biomarkers in this pathology and more investigations are required not only to identify salivary levels and the polymorphism evaluated, but also other interleukins and polymorphisms in order to clarify the etiopathogenesis of this syndrome as well as for propose new diagnostic methods and treatments.

Polymorphisms of the serotonin receptors genes in patients with bruxism: a systematic reviewThis study aimed to investigate if SNP rs6313, SNP rs2770304, SNP rs4941573, and SNP rs1923884 of the 5-HT2A receptor gene and SNP rs6295 of the 5-HT1A receptor gene are associated with bruxism etiology.Methodology: This systematic review was registered in PROSPERO (CRD42018094561). A search was conducted for articles published in or before May 2021. To qualify for eligibility in this review, the studies had to be case-controls, cohort or cross-sectional. The inclusion criteria were the articles with a group of patients with bruxism and a control group in which the presence of these SNPs was evaluated. The exclusion criteria were the investigations of other polymorphisms, the studies that did not consider a control group for comparison, case reports, and reviews. The NOS and JBI were used to evaluate the methodological quality of studies. Results:We conducted this study with databases, such as Web of Science, Scopus, Embase, PubMed/MEDLINE, and ProQuest. We considered four studies eligible. A total of 672 participants were included,187 with sleep bruxism, 105 with awake bruxism, 89 with sleep and awake bruxism, and 291 controls. One study found a strong association between the SNPs rs6313, rs2770304 and rs4941573 of the 5-HT2A receptor gene and sleep bruxism. In one study, we considered the C allele of the SNP rs2770304 a risk factor for sleep bruxism.We found no significant results of other SNPs in sleep bruxers compared to controls. We found no positive association concerning the SNPs and groups of awake bruxism and sleep and awake bruxism. Conclusion: The different results regarding the SNPs in sleep bruxers could be explained by the genetic distinction between Chilean, Mexican, Japanese, and Polish population. More clinical trials and prospective studies must be conducted with larger sample size and in different ethnicities to confirm the results of this review.

Globally around 34 million children present disabling hearing loss. If unaddressed, hearing loss can negatively impact several aspects such as communication, cognition, language, and speech. Most needy people with hearing impairment do not have access to treatments and it’s a national and international public health problem. Meningococcal disease is caused by the bacterium Neisseria meningitides, affects mainly children, can cause hearing loss, and is a global public health challenge. This study aimed to present the case report of a child who acquired meningococcal disease and bilateral profound sensorineural hearing loss in primary infancy. At the age of six months, the child acquired meningococcal meningitis and performed antibiotic therapeutics. Four years later, the audiometric evaluation detected hearing loss. At the age of seven years, the patient started speech language therapy sessions. At the age of nine years, hearing prostheses were provided by a hospital. At the age of ten, the child began to deny the use of hearing aids at home and school. Two years later, she started her studies at a special school where the deaf community is clearly present. At the age of fourteen, the patient became completely fluent in Sign language, stopping speech therapy sessions. The analyzed case demonstrated a lack of children’s surveillance by a multidisciplinary team and the relevance of following children’s guidance vaccination. It is required to provide adequate interventions for children with hearing loss, which can potentially aid them to develop their skills and to achieve a better quality of life.

This study aimed to describe a set of global health postgraduate programs profile, emphasizing the importance of promoting education and training in this field to meet global health challenges and ameliorate health outcomes. The present review is in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analysis Extension for Scoping Reviews (PRISMA-ScR) checklist and the Scoping Review Methods Manual proposed by the Joanna Briggs Institute. Eligibility criteria were a set of lato sensu or stricto sensu postgraduate educational programs of global health or lato sensu or stricto sensu postgraduate programs of public health that present a global health concentration area. The search yielded 707 studies: MEDLINE/PubMed, Web of Science, and LILACS. A total of 441 studies and their authors’ institutional affiliations were analyzed and 101 institutions that offer educational programs were identified. Most postgraduate programs in Global Health or Public health with a concentration area in Global health are master’s degrees, and many of them are taught online. The majority of educational programs are offered by institutions in Europe and North America.
