Probiotic potential of lactic acid bacteria present in home made curd in southern India

Background & objectives: The human gut microbiota play a significant role in nutritional processes. The concept of probiotics has led to widespread consumption of food preparations containing probiotic microbes such as curd and yogurt. Curd prepared at home is consumed every day in most homes in southern India. In this study the home-made curd was evaluated for lactic acid bacteria (LAB) with probiotic potential. Methods: Fifteen LAB (12 lactobacilli, 1 l0 actococcus , 2 Leuconostoc) and one yeast isolated from home-made curd were evaluated for resistance to acid, pepsin, pancreatin and bile salts; antimicrobial resistance; intrinsic antimicrobial activity; adherence to Caco-2 epithelial cells; ability to block pathogen adherence to Caco-2 cells; ability to inhibit interleukin (IL)-8 secretion from HT-29 epithelial cells in response to Vibrio cholerae; and ability to induce anti-inflammatory cytokine expression in THP-1 monocyte cells. Results: Lactobacillus abundance in fermenting curd peaked sharply at 12 h. Nine of the strains survived exposure to acid (pH 3.0) for at least one hour, and all strains survived in the presence of pancreatin or bile salts for 3 h. None showed haemolytic activity. All were resistant to most antimicrobials tested, but were sensitive to imipenem. Most strains inhibited the growth of Salmonella Typhimurium while five inhibited growth of V. cholerae O139. Seven strains showed adherence to Caco-2 cells ranging from 20-104 per cent of adherence of an adherent strain of Escherichia coli, but all inhibited V. cholerae adherence to Caco-2 cells by 20-100 per cent. They inhibited interleukin-8 secretion from HT-29 cells, in response to V. cholerae, by 50-80 per cent. Two strains induced IL-10 and IL-12 messenger ribonucleic acid (mRNA) expression in THP-1 cells. Interpretation & conclusions: LAB in curd had properties consistent with probiotic potential, but these were not consistent across species. LAB abundance in curd increased rapidly at 12 h of fermentation at room temperature and declined thereafter

Pharmacological interventions for self-harm in adults

This is a protocol for a Cochrane Review (intervention). The objectives are as follows: To assess the effects of pharmacological agents or natural products for self‐harm (SH) compared to comparison types of treatment (e.g. placebo or alternative pharmacological treatment) for adults (aged 18 years or older) who engage in SH

Acceptability and Potential Impact of the #chatsafe Suicide Postvention Response Among Young People Who Have Been Exposed to Suicide: Pilot Study

BackgroundYoung people are more likely to be affected by suicide contagion, and there are concerns about the role social media plays in the development and maintenance of suicide clusters or in facilitating imitative suicidal behavior. However, social media also presents an opportunity to provide real-time and age-appropriate suicide prevention information, which could be an important component of suicide postvention activities. ObjectiveThis study aimed to test an intervention designed to equip young people to communicate safely online about suicide (#chatsafe) with a sample of young people who had recently been exposed to a suicide or suicide attempt, with a view to determining the role social media can play as part of a postvention response. MethodsA sample of 266 young people from Australia, aged 16 to 25 years, were recruited to participate in the study. They were eligible if they had been exposed to a suicide or knew of a suicide attempt in the past 2 years. All participants received the #chatsafe intervention, which comprised 6 pieces of social media content that were sent to them weekly via direct message through Instagram, Facebook, or Snapchat. Participants were assessed on a range of outcome measures (social media use, willingness to intervene against suicide, internet self-efficacy, confidence, and safety when communicating about suicide on social media platforms) at baseline, immediately after the intervention, and at 4-week follow-up. ResultsAfter the 6-week #chatsafe intervention, participants reported substantial improvements in their willingness to intervene against suicide online, their internet self-efficacy, and their perceived confidence and safety when communicating about suicide online. Overall, the participants reported that it was appropriate to receive the #chatsafe intervention via social media, and no iatrogenic effects were recorded. ConclusionsThe findings suggest that it is safe and acceptable to disseminate suicide prevention information entirely via social media among young people who have recently been exposed to a suicide or suicide attempt. Interventions such as #chatsafe could potentially mitigate the risk of distress and future suicidal behavior in young people by improving the quality and safety of online communication about suicide and, as such, can be an important component of delivering a postvention response to young people

Characteristics of self-harm presentations to the emergency department of the Royal Melbourne Hospital, 2012-2019 : data from the self-harm monitoring system for Victoria

Background: Rates of self-harm and suicide are increasing world-wide, particularly in young females. Emergency departments (EDs) are a common first point-of-contact for young people who self-harm. We examined age- and sex-related differences in: (1) rates of self-harm over an eight-year period; (2) changes in demographic, presentation, and treatment characteristics over this period, and; (3) rates of, and time to, self-harm re-presentation. Methods: This was a retrospective observational study of all self-harm presentations in persons aged nine years and older to the Royal Melbourne Hospital ED over an eight-year period, 1 January 2012–31 December 2019. The Royal Melbourne Hospital is one of the largest and busiest public EDs in Melbourne, Australia and serves a primary catchment area of approximately 1.5 million people. Results: There were 551,692 presentations to the Royal Melbourne Hospital ED over this period (57.6 % by females). Of these, 7736 (1.4 %) were self-harm related. These self-harm presentations involved 5428 individuals (54.8 % female), giving an overall repetition event-rate of 11.2 %. Self-harm related presentations increased by 5 % per year (Incidence Rate Ratio [IRR 1.05, 95 % CI 1.02–1.08); a 44 % increase over the eight-year period (IRR 1.44, 95 % CI 1.15–1.80). This increase was more pronounced for young people aged< 25 years. The most common method was self-poisoning, primarily by anxiolytics or analgesics. The proportion of presentations involving self-poisoning alone declined modestly over time, whilst the proportion involving self-injury alone increased. For just over half of all presentations the person was seen by ED mental health staff. The median time to first re-presentation was 4.5 months (Inter-Quartile Range [IQR] 0.7–13.2 months). Conclusions: Rates of hospital presenting self-harm may be increasing, particularly amongst young people, whilst most self-harm presentations occurred outside office hours; so appropriate ED staffing, training and clinical care models are needed. Around half of those with a repeat episode of self-harm repeated within three months of their index (i.e., first recorded) presentation. Efforts to establish appropriate aftercare services, including alternatives to ED services with service availability 24 h a day 7 days a week, aimed at reducing repetition rates, should be prioritised

Testing the Impact of the #chatsafe Intervention on Young People’s Ability to Communicate Safely About Suicide on Social Media: Protocol for a Randomized Controlled Trial

Background: Suicide is the leading cause of death among Australians. One commonly cited explanation is the impact of social media, in particular, the ways in which young people use social media to communicate about their own experiences and their exposure to suicide-related content posted by others. Guidelines designed to assist mainstream media to safely report about suicide are widespread. Until recently, no guidelines existed that targeted social media or young people. In response, we developed the #chatsafe guidelines and a supporting social media campaign, which together make up the #chatsafe intervention. The intervention was tested in a pilot study with positive results. However, the study was limited by the lack of a control group. Objective: The aim of this study is to assess the impact of the #chatsafe social media intervention on young people’s safety and confidence when communicating on the web about suicide. Methods: The study employs a pragmatic, parallel, superiority randomized controlled design. It will be conducted in accordance with the Consolidated Standards of Reporting Trials statement over 18 months. Participants will be 400 young people aged 16-25 years (200 per arm). Participants will be recruited via social media advertising and assessed at 3 time points: time 1—baseline; time 2—8-week postintervention commencement; and time 3—4-week postintervention. They will be asked to complete a weekly survey to monitor safety and evaluate each piece of social media content. The intervention comprises an 8-week social media campaign including social media posts shared on public Instagram profiles. The intervention group will receive the #chatsafe suicide prevention content and the control group will receive sexual health content. Both groups will receive 24 pieces of content delivered to their mobile phones via text message. The primary outcome is safety when communicating on the web about suicide, as measured via the purpose-designed #chatsafe online safety questionnaire. Additional outcomes include willingness to intervene against suicide, internet self-efficacy, safety, and acceptability. Results: The study was funded in November 2020, approved by the University of Melbourne Human Research Ethics Committee on October 7, 2022, and prospectively registered with the Australian New Zealand Clinical Trials registry. Trial recruitment began in November 2022 and study completion is anticipated by June 2024. Conclusions: This will be the first randomized controlled trial internationally to test the impact of a social media intervention designed to equip young people to communicate safely on the web about suicide. Given the rising rates of youth suicide in Australia and the acceptability of social media among young people, incorporating social media–based interventions into the suicide prevention landscape is an obvious next step. This intervention, if effective, could also be extended internationally, thereby improving web-based safety for young people not just in Australia but globally
