Effect of chemical preservatives on shelf life of mushroom (Pleurotus ostreatus) cultivated on cassava peels

Short shelf life is a major impediment to the processing and distribution of mushroom. The effect of chemical preservatives on some quality attributes of mushroom during storage was investigated. Mushroom were soaked in four preservatives at two concentrations for 10 mins, packaged, stored at 4 °C for 30 days and analysed at intervals for their microbial population, colour, firmness and weight loss. Sodium benzoate (0.05%, 0.1%) lost its preservative effect on all the micro-organisms enumerated after 3 days, and samples treated with 0.1% potassium sorbate had the lowest microbial load at the end of the storage period. Change in colour of the potassium sorbate (0.1%)-treated sample was lower than and significantly different from the citric acid (2%, 4%)-treated samples. The values of the firmness of the 4% citric acid preserved mushroom were significantly different (P ≤ 0.05) from other samples throughout the storage period. There was a significant negative correlation (r = −0.807, P < 0.01) between the firmness and weight loss of the preserved mushroom. Potassium sorbate (0.1%) and citric acid (4%) extended the shelf life of mushroom for 24 days

Towards Ending the HIV Epidemic in the US: State of Human Immunodeficiency Virus Screening during Physician and Emergency Department Visits, 2009 -2014

Human immunodeficiency virus (HIV) testing is important for prevention and treatment. Ending the HIV epidemic is unattainable if significant proportions of people living with HIV remain undiagnosed, making HIV testing critical for prevention and treatment. The Centers for Disease Control and Prevention (CDC) recommends routine HIV testing for persons aged 13 to 64 years in all health care settings. This study builds on prior research by estimating the extent to which HIV testing occurs during physician office and emergency department (ED) post 2006 CDC recommendations. We performed an unweighted and weighted cross-sectional analysis using pooled data from 2 nationally representative surveys namely National Ambulatory Medical Care Survey and National Hospital Ambulatory Medical Care Survey from 2009 to 2014. We assessed routine HIV testing trends and predictive factors in physician offices and ED using multi-stage statistical survey procedures in SAS 9.4. HIV testing rates in physician offices increased by 105% (5.6–11.5 per 1000) over the study period. A steeper increase was observed in ED with a 191% (2.3–6.7 per 1000) increase. Odds ratio (OR) for HIV testing in physician offices were highest among ages 20 to 29 ([OR] 7.20, 99% confidence interval [CI: 4.37–11.85]), males (OR 1.34, [CI: 0.91–0.93]), African-Americans (OR 2.97, [CI: 2.05–4.31]), Hispanics (OR 1.80, [CI: 1.17–2.78]), and among visits occurring in the South (OR 2.06, [CI: 1.23–3.44]). In the ED, similar trends of higher testing odds persisted for African Americans (OR 3.44, 99% CI 2.50–4.73), Hispanics (OR 2.23, 99% CI 1.65–3.01), and Northeast (OR 2.24, 99% CI 1.10–4.54). While progress has been made in screening, HIV testing rates remains sub-optimal for ED visits. Populations visiting the ED for routine care may suffer missed opportunities for HIV testing, which delays their entry into HIV medical care. To end the epidemic, new approaches for increasing targeted routine HIV testing for populations attending health care settings is recommended

Factors Associated with HIV Discussion and Condom Use with Sexual Partners in an Underserved Community in South Africa

We examined factors associated with discussing HIV and condom use with a sexual partner. Two cross-sectional surveys were conducted in 2004 prior to the implementation of an HIV awareness campaign in a South African community and in 2008 after a three-year education program. Overall, the proportion of individuals who had discussed HIV with a sexual partner increased from 76% in 2004 to 89% in 2008 (p < .001). Among respondents who had sex six months before completing the surveys, condom use significantly increased from 64% in 2004 to 79% in 2008 (p < .05). Respondents who discussed HIV with a sexual partner were more likely to use condoms than respondents who had not discussed HIV with a sexual partner (OR=2.08, 95% CI=1.16, 3.72). These findings indicate the importance of interventions aimed at promoting HIV awareness and discussion of HIV in communities with individuals at risk of acquiring HIV

Attitudes Toward Intimate Partner Violence and Associations With Condom Use Among Men in Haiti: An Analysis of the Nationally Representative Demographic Health Survey

Although men have substantial decision-making power regarding condom use, the majority of HIV knowledge and prevention studies in the general Haitian population have been conducted among youth and women. We investigated attitudes towards intimate partner violence, knowledge of and use of condoms among 9,493 men in Haiti using data from the 2012 nationally representative Demographic and Health Survey. Only 36% of HIV-negative and 44% of HIV-positive men reported using a condom the last time they had sex. Logistic regression revealed that believing it was justified for a man to hit or beat his wife if she refuses to have sex with him was associated with a lower odds of condom use. The odds of using a condom during last sex was higher among men who reported knowing condoms can prevent HIV and who had been tested for HIV. Given the low rate of condom use among men in Haiti, these findings suggest that interventions promoting HIV knowledge, HIV testing, and gender-violence prevention among men may also increase condom use

Preparing for Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) Self-Testing Implementation: Lessons Learned From HIV Self-Testing

The number of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) cases and associated death continue to rise globally. Widespread testing for SARS-CoV-2 infection is crucial in order to identify individuals who need to need to be isolated, thereby reducing their chances to infect others and allowing them to seek treatment earlier which can prevent further negative health outcomes and mortality. Currently, the most common testing method for SARS-CoV-2 diagnosis is Real-Time Polymerase Chain Reaction (RT-PCR) from nasopharyngeal, throat or saliva specimens. However, SARS-CoV-2 testing has been hampered in many countries due to inadequate test kits, uncomfortable testing procedures, shortages of personal protective equipment (PPE) for health care workers, and low demand among people to seek testing for SARS-CoV-2 at health facilities

Systematic review of mobile health behavioural interventions to improve uptake of HIV testing for vulnerable and key populations

This systematic narrative review examined the empirical evidence on the effectiveness of mobile health (mHealth) behavioral interventions designed to increase uptake of HIV testing among vulnerable and key populations

HIV testing barriers and intervention strategies among men, transgender women, female sex workers and incarcerated persons in the Caribbean: a systematic review

BACKGROUND: This systematic review summarises evidence on the HIV testing barriers and intervention strategies among Caribbean populations and provides pertinent implications for future research endeavours designed to increase rates of HIV testing in the region. METHODS: We used a systematic approach to survey all literature published between January 2008 and November 2018 using four electronic databases (MEDLINE/PubMed, Embase, Web of Science and Global Health). Only peer-reviewed articles published in English that examined HIV testing uptake and interventions in the Caribbean with men, men who have sex with men, female sex workers, transgender women and incarcerated individuals were included. RESULTS: Twenty-one studies met the inclusion criteria. Lack of confidentiality, access to testing sites, stigma, discrimination, poverty and low HIV risk perception were identified as key barriers to HIV testing. These barriers often contributed to late HIV testing and were associated with delayed treatment initiation and decreased survival rate. Intervention strategies to address these barriers included offering rapid HIV testing at clinics and HIV testing outreach by trained providers and peers. CONCLUSION: HIV testing rates remain unacceptably low across the Caribbean for several reasons, including stigma and discrimination. Future HIV testing interventions should target places where at-risk populations congregate, train laypersons to conduct rapid tests and consider using oral fluid HIV self-testing, which allows individuals to test at home

Effectiveness of Interventions Promoting HIV Serostatus Disclosure to Sexual Partners: A Systematic Review

Disclosure of HIV serostatus to sexual partners is mandated within certain states in the United States and other countries. Despite these laws implemented and public health efforts to increase disclosure, rates of disclosure to sexual partners among people living with HIV (PLWH) remain low, suggesting the need for interventions to assist PLWH with the disclosure process. We conducted a systematic review of studies testing whether HIV serostatus disclosure interventions increase disclosure to sexual partners. We searched six electronic databases and screened 484 records. Five studies published between 2005 and 2012 met inclusion criteria and were included in this review. Results showed that three of the HIV serostatus disclosure-related intervention studies were efficacious in promoting disclosure to sexual partners. Although all three studies were conducted in the United States the intervention content and measurements of disclosure across the studies varied, so broad conclusions are not possible. The findings suggest that more rigorous HIV serostatus disclosure-related intervention trials targeting different populations in the United States and abroad are needed to facilitate disclosure to sexual partners
