The role of gut microbiota on cognitive development in rodents: a meta-analysis.

Cognitive function includes learning, remembering and using acquired information. Emerging studies indicate the correlation between microbiota and cognitive function. Higher abundance of a specific gut microbiota, such as Bacteroidetes may improve cognitive abilities. However, another study reported different result. These results suggest that further systematic analysis is required to determine the effect of the gut microbiota abundance on cognitive development. The aim of this study is to summarize the abundance of the specific gut microbiota and cognitive development using meta-analysis. PubMed, ScienceDirect, and Clinical-Key were used as data bases to perform the literature search. Phylum Bacteroidetes, and family Lactobacillaceae were more abundant in cognitive-behavioral enhancement (CBE), whereas Firmicutes, Proteobacteria, Actinobacteria, and family Ruminococcaceae were less abundant in CBE. Differences in gut microbiota abundance are influenced by differences in stage of cognitive dysfunction, intervention, and strain of gut microbiota.

Electronic Media Use and Sleep Disorders among Adolescents during the COVID-19 Pandemic.

BACKGROUND: One of the negative impacts of electronic media use is the occurrence of sleep disturbances. Due to the COVID-19 pandemic, the use of electronic media in families, including in adolescents, has been increasing. OBJECTIVE: This study was aimed at describing the association between electronic media use and sleep disturbances in adolescents in Palembang. METHODS: A cross-sectional study was conducted in January to February 2021. Participants were 14-17-year-old high school students who completed a questionnaire to assess electronic media use and a Sleep Disturbance Scale for Children (SDSC) questionnaire to assess sleep disturbances. RESULTS: One hundred and fifty-seven participants enrolled in this study. The majority of the participants were 16 years old or older (56.7%) and used smartphones (93%) with a median of media use of 10 hours a day. None of the participants' characteristic variables showed statistically significant correlations. Similarly, none of the electronic media use variables showed statistically significant correlations. CONCLUSION: Most of adolescents in this study have used electronic media for more than 6 years, with median use of 10 hours per day, for noneducative purposes. Despite findings that most of them experience sleep disturbances, there was no statistically significant association between electronic media use and sleep disturbances in adolescents.

Irritable bowel syndrome in Indonesian adolescents

Abstract Objective: Irritable bowel syndrome is a frequent functional gastrointestinal disorder. The aims of this study were to investigate its epidemiology, focusing on the role of intestinal mucosal integrity and to evaluate the impact on the quality of life. Methods: A community-based survey applying a comparative cross sectional approach was conducted in six high schools in Palembang. Subjects were recruited using multistage random sampling divided in two groups. Rome III criteria were used to establish a diagnosis of IBS in combination with a questionnaire to determine risk factors. Determination of fecal alpha-1-antitrypsin and calprotectin levels was performed to determine impaired intestinal mucosal integrity. A questionnaire was used to evaluate how quality of life was affected by irritable bowel syndrome. Results: The survey was performed in 454 14−18 years old adolescents, of whom 30.2% fulfilled the Rome III criteria for IBS, with the following subtypes: 36.5% diarrhea, 18.9% constipation, 21.9% mixed, and 22.6% unclassified. Major risk factors were female gender, bullying, age 14-16 years, history of constipation and diarrhea, eating nuts, and drinking coffee, tea, and soft drinks. There was a significant association with intestinal inflammation (p = 0.013). A significantly impaired quality of life was found (p = 0.001). Conclusions: The prevalence of irritable bowel syndrome in adolescents was high, with bullying, female gender, age 14-16 years, constipation and diarrhea, and dietary consumption of soft drinks, coffee, and tea as risk factors. A significant association with intestinal inflammation was found.

Association Between Irritable Bowel Syndrome and Sleep Disturbance in Adolescents.

INTRODUCTION: Sleep disorder in adolescents is a problem that is rarely considered by both parents and healthcare professionals. Ignorance of sleep disorders is likely caused by the very rare occurrence of associated sporadic or emergency cases. Irritable bowel syndrome (IBS) is a functional gastrointestinal disorder characterized by abdominal pain and changes in the defecation pattern. Previous research has demonstrated IBS as one of the many causes of sleep disorders. Difficulty sleeping, frequent awakening, and difficulty returning to sleep after awakening are the symptoms often experienced by adolescents with IBS. The high incidence of IBS in adolescents and the large proportion of sleep disorders in IBS affect the quality of life and disrupt physical development, behaviour, and learning achievement. The relationship between IBS and sleep disorders in adolescents needs to be studied. This study aims to determine the relationship between sleep disorders and IBS in high school adolescents in Palembang. METHODS: This is a cross-sectional study conducted on 294 high school adolescents in Palembang in June 2018. Random sampling method was used and the presence of IBS and sleep disturbances were assessed using a questionnaire. RESULTS: Among all subjects, we found 113 subjects (38.4%) with IBS. Of these 113 subjects with IBS, only 60 subjects (53.1%) experienced sleep disorders. CONCLUSION: No correlation found between sleep disorders and IBS in adolescents.

Blastocystis ST-1 is associated with Irritable Bowel Syndrome-diarrhoea (IBS-D) in Indonesian adolescences.

OBJECTIVE: IBS is a functional gastrointestinal disorder and commonly presents in children and adolescences, presented as diarrhoea, constipation or mixed type. Blastocystis is a common intestinal protozoa found worldwide, which pathogenicity is still controversial. This study aimed to identify the risk factors of IBS, the association between IBS types with Blastocystis subtypes and analyse Blastocystis pathogenicity. DESIGN: A comparative cross-sectional study was conducted among senior high school students. Rome III Criteria for IBS diagnosis, questionnaires on the risk factors of IBS and types of IBS were recorded. Students were further selected and classified into IBS and non-IBS groups to analyse the association between IBS, IBS types with Blastocystis infection and its subtypes. Direct microscopic stool examination to identify single Blastocystis infection was performed, followed by culture in Jones' medium, PCR, sequencing of 18S rRNA and phylogenetic analysis to determine Blastocystis subtype. Data was analysed using SPSS v22.0 and P value <0.05 was considered statistically significant (95% confidence intervals). RESULTS: IBS was found in 30.2% of 454 students, consisted of 33.3% IBS Diarrhoea, 27.7% IBS Mixed, 27.7% IBS Unclassified and 11.1% IBS Constipation. Major risk factors to IBS consisted of family history of recurrent abdominal pain, abuse, bullying and female gender in respective order (OR 3.6-2.1). Blastocystis ST-1 was significantly associated to IBS-D with 2.9 times risk factor. CONCLUSIONS: Blastocystis infection is a risk factor to develop IBS-D type in adolescence; Blastocystis ST-1 can be regarded as a pathogenic subtype.
