From hearth to hard drive: well-being benefits of online Irish traditional singing sessions during COVID-19.

This article explores the impact of online Irish traditional singing sessions on health and well-being during the COVID-19 pandemic. Singing sessions are unique facets of Ireland's music tradition that saw dramatic closure, interruption and digital transition in response to COVID-19 social distancing measures. This study highlights a gap in health promotion literature with regard to traditional singing sessions as a group singing activity and examines the potential for online group singing activities to have positive impacts on the health and well-being of participants. While traditional singing sessions foreground solo performances, they are quintessentially group activities, and include community engagement and active participation from singers and listeners alike. Through an online survey (n = 108), and ethnographic interviews (n = 3), this study explores potential health and well-being implications of online traditional singing sessions, and reveals four main areas of impact: social connection, enjoyment, cognitive motivation and timekeeping. The study suggests that online traditional singing sessions can promote health and well-being in participants, particularly during times of isolation.

This article explores the impact of online Irish traditional singing sessions on health and well-being during the COVID-19 pandemic. Singing sessions are unique facets of Ireland's music tradition which were forced to move online due to COVID-19 restrictions. This study used an online survey (n = 108), and interviews (n = 3), to explore the impact of these online sessions on the well-being of their participants. Findings showed the impacts to be overwhelmingly positive, particularly in four main areas: social connection, enjoyment, cognitive motivation, and timekeeping. This study highlights the value of traditional singing sessions as group singing activities for the purposes of health and well-being promotion, and suggests that online group singing activities can be beneficial, particularly during times of isolation.

Mucosal trafficking of vector-specific CD4+ T lymphocytes following vaccination of rhesus monkeys with adenovirus serotype 5.

Post hoc analysis of the phase 2b Step study evaluating a recombinant adenovirus serotype 5 (rAd5)-based HIV-1 vaccine candidate suggested a potential increased risk of HIV-1 acquisition in subjects who were baseline Ad5 seropositive and uncircumcised. These concerns had a profound impact on the HIV-1 vaccine development field, although the mechanism underlying this observation remains unknown. It has been hypothesized that rAd5 vaccination of baseline Ad5-seropositive individuals may have resulted in anamnestic, vector-specific CD4(+) T lymphocytes that could have trafficked to mucosal sites and served as increased targets for HIV-1 infection. Here we show that Ad5-specific CD4(+) T lymphocyte responses at mucosal sites following rAd5-Gag/Pol/Nef vaccination were comparable in rhesus monkeys with and without baseline Ad5 immunity. Moreover, the total cellular inflammatory infiltrates and the CD3(+), CD4(+), HLA-DR(+), Ki67(+), and langerin(+) cellular subpopulations in colorectal and foreskin mucosa were similar in both groups. Thus, no greater trafficking of Ad5-specific CD4(+) T lymphocytes to mucosal target sites was observed following rAd5 vaccination of rhesus monkeys with baseline Ad5 immunity. These findings from this nonhuman primate model provide evidence against the hypothesis that recruitment of vector-specific target cells to mucosal sites led to increased HIV-1 acquisition in Ad5-seropositive, uncircumcised vaccinees in the Step study.

Contributions of Mamu-A*01 status and TRIM5 allele expression, but not CCL3L copy number variation, to the control of SIVmac251 replication in Indian-origin rhesus monkeys.

CCL3 is a ligand for the HIV-1 co-receptor CCR5. There have recently been conflicting reports in the literature concerning whether CCL3-like gene (CCL3L) copy number variation (CNV) is associated with resistance to HIV-1 acquisition and with both viral load and disease progression following infection with HIV-1. An association has also been reported between CCL3L CNV and clinical sequelae of the simian immunodeficiency virus (SIV) infection in vivo in rhesus monkeys. The present study was initiated to explore the possibility of an association of CCL3L CNV with the control of virus replication and AIDS progression in a carefully defined cohort of SIVmac251-infected, Indian-origin rhesus monkeys. Although we demonstrated extensive variation in copy number of CCL3L in this cohort of monkeys, CCL3L CNV was not significantly associated with either peak or set-point plasma SIV RNA levels in these monkeys when MHC class I allele Mamu-A*01 was included in the models or progression to AIDS in these monkeys. With 66 monkeys in the study, there was adequate power for these tests if the correlation of CCL3L and either peak or set-point plasma SIV RNA levels was 0.34 or 0.36, respectively. These findings call into question the premise that CCL3L CNV is important in HIV/SIV pathogenesis.

Motivating people to learn cardiopulmonary resuscitation and use of automated external defibrillators.

The purpose of this study was to test the effect of a motivational message on the intention of laypersons to learn cardiopulmonary resuscitation (CPR) and automated external defibrillator (AED) use. A pretest-posttest, double-blind, randomized design was used with 220 community-dwelling adults. Participants were randomly assigned to the treatment group reading the CPR and AED pamphlet emphasizing learning CPR and AED use to save someone they love and the 3-minute window for response time; or to the comparison group reading the identical pamphlet without the 2 motivational statements. Intention to learn CPR and AED use and to look for AEDs in public areas was measured before and after reading the respective pamphlet. No significant difference emerged between the groups for the number of participants planning to learn CPR and AED use. A significant number of participants in both groups increased intention to learn CPR and AED use. Significantly more treatment participants than comparison participants planned to routinely look for AEDs in public areas after reading the pamphlet, however. Teaching critical facts such as the low survival rate for out-of-hospital cardiac arrest might encourage laypersons to learn CPR and AED use. Routinely teaching family members of people at risk for a cardiac arrest about the short window of time in which CPR and AED use must begin and encouraging them to learn about CPR and AEDs to save someone they love may encourage family members to identify the location of AEDs in public places.

Mosaic HIV-1 vaccines expand the breadth and depth of cellular immune responses in rhesus monkeys.

The worldwide diversity of HIV-1 presents an unprecedented challenge for vaccine development. Antigens derived from natural HIV-1 sequences have elicited only a limited breadth of cellular immune responses in nonhuman primate studies and clinical trials to date. Polyvalent 'mosaic' antigens, in contrast, are designed to optimize cellular immunologic coverage of global HIV-1 sequence diversity. Here we show that mosaic HIV-1 Gag, Pol and Env antigens expressed by recombinant, replication-incompetent adenovirus serotype 26 vectors markedly augmented both the breadth and depth without compromising the magnitude of antigen-specific T lymphocyte responses as compared with consensus or natural sequence HIV-1 antigens in rhesus monkeys. Polyvalent mosaic antigens therefore represent a promising strategy to expand cellular immunologic vaccine coverage for genetically diverse pathogens such as HIV-1.

Adenovirus-specific immunity after immunization with an Ad5 HIV-1 vaccine candidate in humans.

The immunologic basis for the potential enhanced HIV-1 acquisition in adenovirus serotype 5 (Ad5)-seropositive individuals who received the Merck recombinant Ad5 HIV-1 vaccine in the STEP study remains unclear. Here we show that baseline Ad5-specific neutralizing antibodies are not correlated with Ad5-specific T lymphocyte responses and that Ad5-seropositive subjects do not develop higher vector-specific cellular immune responses as compared with Ad5-seronegative subjects after vaccination. These findings challenge the hypothesis that activated Ad5-specific T lymphocytes were the cause of the potential enhanced HIV-1 susceptibility in the STEP study.

Protective efficacy of a single immunization of a chimeric adenovirus vector-based vaccine against simian immunodeficiency virus challenge in rhesus monkeys.

Rare serotype and chimeric recombinant adenovirus (rAd) vectors that evade anti-Ad5 immunity are currently being evaluated as potential vaccine vectors for human immunodeficiency virus type 1 and other pathogens. We have recently reported that a heterologous rAd prime-boost regimen expressing simian immunodeficiency virus (SIV) Gag afforded durable partial immune control of an SIV challenge in rhesus monkeys. However, single-shot immunization may ultimately be preferable for global vaccine delivery. We therefore evaluated the immunogenicity and protective efficacy of a single immunization of chimeric rAd5 hexon hypervariable region 48 (rAd5HVR48) vectors expressing SIV Gag, Pol, Nef, and Env against a homologous SIV challenge in rhesus monkeys. Inclusion of Env resulted in improved control of peak and set point SIV RNA levels following challenge. In contrast, DNA vaccine priming did not further improve the protective efficacy of rAd5HVR48 vectors in this system.

Attitudes of Kentucky women regarding mandatory reporting of intimate partner violence.

BACKGROUND: Kentucky is one of only six states with laws mandating that intimate partner violence be reported to authorities. The purpose of this project was to understand the attitudes of women clinic patients in Kentucky regarding mandatory reporting of intimate partner violence and how these attitudes may differ by abuse status. METHODS: Women presenting to an internal medicine clinic in the summer of 2003 were asked to complete an anonymous 30-item questionnaire, including personal history of abuse and their opinions about mandatory reporting of intimate partner violence to the police. RESULTS: Surveys were completed by 238 women, of which 29% reported a history of intimate partner violence. Of abused women, 49% supported mandatory reporting of intimate partner violence to the police, compared to 61% of women without an abuse history (p = 0.05) CONCLUSION: Women with a history of abuse are more ambivalent about mandatory reporting of intimate partner violence to the police than women without a history of abuse.

Immune control of an SIV challenge by a T-cell-based vaccine in rhesus monkeys.

A recombinant adenovirus serotype 5 (rAd5) vector-based vaccine for HIV-1 has recently failed in a phase 2b efficacy study in humans. Consistent with these results, preclinical studies have demonstrated that rAd5 vectors expressing simian immunodeficiency virus (SIV) Gag failed to reduce peak or setpoint viral loads after SIV challenge of rhesus monkeys (Macaca mulatta) that lacked the protective MHC class I allele Mamu-A*01 (ref. 3). Here we show that an improved T-cell-based vaccine regimen using two serologically distinct adenovirus vectors afforded substantially improved protective efficacy in this challenge model. In particular, a heterologous rAd26 prime/rAd5 boost vaccine regimen expressing SIV Gag elicited cellular immune responses with augmented magnitude, breadth and polyfunctionality as compared with the homologous rAd5 regimen. After SIV(MAC251) challenge, monkeys vaccinated with the rAd26/rAd5 regimen showed a 1.4 log reduction of peak and a 2.4 log reduction of setpoint viral loads as well as decreased AIDS-related mortality as compared with control animals. These data demonstrate that durable partial immune control of a pathogenic SIV challenge for more than 500 days can be achieved by a T-cell-based vaccine in Mamu-A*01-negative rhesus monkeys in the absence of a homologous Env antigen. These findings have important implications for the development of next-generation T-cell-based vaccine candidates for HIV-1.

Comparative seroprevalence and immunogenicity of six rare serotype recombinant adenovirus vaccine vectors from subgroups B and D.

Recombinant adenovirus serotype 5 (rAd5) vector-based vaccines are currently being developed for both human immunodeficiency virus type 1 and other pathogens. The potential limitations associated with rAd5 vectors, however, have led to the construction of novel rAd vectors derived from rare Ad serotypes. Several rare serotype rAd vectors have already been described, but a detailed comparison of multiple rAd vectors from subgroups B and D has not previously been reported. Such a comparison is critical for selecting optimal rAd vectors for advancement into clinical trials. Here we describe the construction of three novel rAd vector systems from Ad26, Ad48, and Ad50. We report comparative seroprevalence and immunogenicity studies involving rAd11, rAd35, and rAd50 vectors from subgroup B; rAd26, rAd48, and rAd49 vectors from subgroup D; and rAd5 vectors from subgroup C. All six rAd vectors from subgroups B and D exhibited low seroprevalence in a cohort of 200 individuals from sub-Saharan Africa, and they elicited Gag-specific cellular immune responses in mice both with and without preexisting anti-Ad5 immunity. The rAd vectors from subgroup D were also evaluated using rhesus monkeys and were shown to be immunogenic after a single injection. The rAd26 vectors proved the most immunogenic among the rare serotype rAd vectors studied, although all rare serotype rAd vectors were still less potent than rAd5 vectors in the absence of anti-Ad5 immunity. These studies substantially expand the portfolio of rare serotype rAd vectors that may prove useful as vaccine vectors for the developing world.

Age dependence of adenovirus-specific neutralizing antibody titers in individuals from sub-Saharan Africa.

We assessed neutralizing antibody titers to adenovirus serotype 5 (Ad5) and six rare adenovirus serotypes, serotypes 11, 35, 50, 26, 48, and 49, in pediatric populations in sub-Saharan Africa. We observed a clear age dependence of Ad5-specific neutralizing antibody titers. These data will help to guide the development of Ad vector-based vaccines for human immunodeficiency virus type 1 and other pathogens.
