ABSTRACT

In the article, the authors review antibiotic treatment options for both acute uncomplicated UTI and complicated UTI. In addition, they review alternative regimens which are needed in the setting of drug-resistant pathogens including vancomycin-resistant Enterococcus, -extended-spectrum beta-lactamase-producing Enterobacterales (ESBL-E), carbapenem-resistant Enterobacterales, and carbapenem-resistant Pseudomonas, which are encountered with more frequency.

ABSTRACT

Immune responses to COVID-19 vaccination are attenuated in adult solid organ transplant recipients (SOTRs) and additional vaccine doses are recommended for this population. However, whether COVID-19 mRNA vaccine responses are limited in pediatric SOTRs (pSOTRs) compared to immunocompetent children is unknown. Due to SARS-CoV-2 evolution and mutations that evade neutralizing antibodies, T cells may provide important defense in SOTRs who mount poor humoral responses. Therefore, we assessed anti-SARS-CoV-2 IgG titers, surrogate neutralization, and spike (S)-specific T-cell responses to COVID-19 mRNA vaccines in pSOTRs and their healthy siblings (pHCs) before and after the bivalent vaccine dose. Despite immunosuppression, pSOTRs demonstrated humoral responses to both ancestral strain and Omicron subvariants following the primary ancestral strain monovalent mRNA COVID-19 series and multiple booster doses. These responses were not significantly different from those observed in pHCs and significantly higher six months after vaccination than responses in adult SOTRs two weeks post-vaccination. However, pSOTRs mounted limited S-specific CD8+ T-cell responses and qualitatively distinct CD4+ T-cell responses, primarily producing IL-2 and TNF with less IFN-γ production compared to pHCs. Bivalent vaccination enhanced humoral responses in some pSOTRs but did not shift the CD4+ T-cell responses toward increased IFN-γ production. Our findings indicate that S-specific CD4+ T cells in pSOTRs have distinct qualities with unknown protective capacity, yet vaccination produces cross-reactive antibodies not significantly different from responses in pHCs. Given altered T-cell responses, additional vaccine doses in pSOTRs to maintain high titer cross-reactive antibodies may be important in ensuring protection against SARS-CoV-2.

ABSTRACT

BACKGROUND: Adolescent solid organ transplant recipients (aSOTRs) who received three doses of the COVID-19 mRNA vaccine experience high seroconversion rates and antibody persistence for up to 3 months. Long-term antibody durability beyond this timeframe following three doses of the SARS-CoV-2 mRNA vaccine remains unknown. We describe antibody responses 6 months following the third vaccine dose (D3) of the BNT162b2 mRNA vaccination among aSOTRs. METHODS: Participants in a multi-center, observational cohort who received the third dose of the vaccine were analyzed for antibodies to the SARS-CoV-2 spike protein receptor-binding domain (Roche Elecsys anti-SARS-CoV-2-S positive: ≥0.8, maximum: >2500 U/mL). Samples were collected at 1-, 3-, and 6-months post-D3. Participants were surveyed at each timepoint and at 12-months post-D3. RESULTS: All 34 participants had positive anti-RBD antibody titers 6 months post-D3. Variations in titers occurred between 3 and 6 months post-D3, with 8/28 (29%) having decreased antibody levels at 6 months compared to 3 months and 2/28 (7%) reporting increased titers at 6 months. The remaining 18/28 (64%) had unchanged antibody titers compared to 3-month post-D3 levels. A total of 4/34 (12%) reported breakthrough infection within 6 months and 3/32 (9%) reported infection after 6-12 months following the third dose of the SARS-CoV-2 mRNA vaccine. CONCLUSIONS: The results suggest that antibody durability persists up to 6 months following three doses of the SARS-CoV-2 mRNA in aSOTRs. Demography and transplant characteristics did not differ for those who experienced antibody weaning. Breakthrough infections did occur, reflecting immune-evasive nature of novel variants such as Omicron.

ABSTRACT

AIM: This qualitative systematic review aimed to synthesise existing qualitative research on HCPs' perceptions and experiences of obesity and its management in primary care settings. BACKGROUND: Healthcare professionals (HCPs), particularly those in primary care, play a key role in policy implementation around weight management. Overweight and obese individuals are subject to weight stigma which has negative health consequences and reduces the likelihood of healthcare service usage. An understanding of HCPs' perceptions of obesity and weight management in primary care is necessary for the development and delivery of effective initiatives. METHODS: A search strategy developed using the SPIDER framework was applied to Medline and CINAHL databases. Inclusion criteria were applied, and quality assessment was undertaken using the CASP framework. Fifteen papers meeting the inclusion criteria were analysed thematically. FINDINGS: Four themes were identified: conflicting discourses surrounding obesity, medicalisation of obesity, organisational factors, and lack of patient knowledge and motivation. Conflicting discourses around obesity refers to the differing views of HCPs regarding what it means to have and treat obesity. Medicalisation of obesity considers whether obesity should be treated as a medical condition. Organisational factors were identified as knowledge, resources and time that affected HCPs' ability to provide care to overweight or obese. Finally, the review discovered that patients required their own knowledge and motivation to lose weight. This review has highlighted the need to provide safe, non-judgemental spaces for HCPs and patients to discuss weight and weight loss. This is essential to the therapeutic relationship and the provision of effective obesity management.

ABSTRACT

SARS-CoV-2 infection during the Omicron period was frequent amongst a cohort of vaccinated pediatric solid organ transplant recipients (pSOTRs) despite robust anti-receptor-binding domain (anti-RBD) antibody response, suggesting poor neutralizing capacity against Omicron subvariants. Breakthrough infections among pSOTRs were overall limited in severity.

ABSTRACT

Children metabolize voriconazole faster than adults and require higher weight-based doses and more frequent administration to achieve therapeutic troughs. We report a case of a 4-year-old girl with disseminated fusariosis with persistently undetectable voriconazole troughs. Omeprazole was added as a CYP2C19-inhibitor to increase voriconazole concentrations. This case highlights the role of omeprazole for voriconazole boosting in a child.

ABSTRACT

BACKGROUND: Limited data are available to guide effective antibiotic durations for hospitalized patients with complicated urinary tract infections (cUTIs). METHODS: We conducted an observational study of patients ≥18 years at 24 US hospitals to identify the optimal treatment duration for patients with cUTI. To increase the likelihood patients experienced true infection, eligibility was limited to those with associated bacteremia. Propensity scores were generated for an inverse probability of treatment weighted analysis. The primary outcome was recurrent infection with the same species ≤30 days of completing therapy. RESULTS: 1099 patients met eligibility criteria and received 7 (n = 265), 10 (n = 382), or 14 (n = 452) days of therapy. There was no difference in the odds of recurrent infection for patients receiving 10 days and those receiving 14 days of therapy (aOR: .99; 95% CI: .52-1.87). Increased odds of recurrence was observed in patients receiving 7 days versus 14 days of treatment (aOR: 2.54; 95% CI: 1.40-4.60). When limiting the 7-day versus 14-day analysis to the 627 patients who remained on intravenous beta-lactam therapy or were transitioned to highly bioavailable oral agents, differences in outcomes no longer persisted (aOR: .76; 95% CI: .38-1.52). Of 76 patients with recurrent infections, 2 (11%), 2 (10%), and 10 (36%) in the 7-, 10-, and 14-day groups, respectively, had drug-resistant infections (P = .10). CONCLUSIONS: Seven days of antibiotics appears effective for hospitalized patients with cUTI when antibiotics with comparable intravenous and oral bioavailability are administered; 10 days may be needed for all other patients.

ABSTRACT

The ways in which health professionals (HPs) interact with individuals from sexual minorities can impact their perception of the health service and influence engagement. This systematic literature review aimed to identify and synthesize the qualitative literature exploring interactions between HPs and lesbian, gay and bisexual (LGB) patients in healthcare settings. A search strategy was developed and applied to CINAHL and Medline, inclusion criteria were then applied to results by two screeners with good agreement. Thematic analysis was carried out on papers meeting the inclusion criteria in three stages, beginning with coding the text line-by-line, developing descriptive themes and finally, analytical themes. Electronic searches identified 348 papers with 20 of these meeting the inclusion criteria. Thematic analysis found five themes; HPs' lack of knowledge regarding LGB specific issues, identification of sexual orientation, discomfort in interactions, LGB patients' experience of heteronormative attitudes and perceived judgment or other negative attitudes.

ABSTRACT

Citizen science is increasing in popularity but remains largely located in the disciplines of environmental and natural sciences. However, it has the potential to be a useful tool in other disciplines such as health. The aim of this study was to identify the factors for involvement (or non-involvement) in health-related citizen science projects using the Our Outdoors citizen science initiative as an example. Our Outdoors aims to understand how urban and rural shared outdoors spaces (e.g., parks, lakes, rivers, beaches) can affect human health and well-being (both positively and negatively). Understanding the motivations for involvement in such a program is likely to be useful for increasing participation rates and involvement. Qualitative research methods were used in this study in which semi-structured interviews were conducted with 12 participants from two community projects in Scotland, United Kingdom. A thematic analysis revealed five key themes pertaining to the factors that motivated engagement with health-related citizen science projects such as Our Outdoors. These include enhancing social connectedness; personal learning development; making a difference in the community; gaining health and well-being benefits; and finally, demotivating factors relating to time constraints and the term "citizen science". This study concludes that emphasising motivating factors in the promotional material for health-related citizen science projects may increase recruitment and the active involvement of participants. Similarly, reducing the presence of demotivating factors and considering the use of the term "citizen science" is likely to encourage participation.

ABSTRACT

BACKGROUND: The importance of engaging stakeholders in the research process is well recognised. Whilst engagement is important, guidelines and practices vary for how stakeholders should be involved in research and how to facilitate effective collaborative relationships. METHODS: This study aimed to explore the perspectives and experiences of stakeholders involved in the policy and practice area of outdoor space and non-communicable disease prevention. Stakeholders interviewed included academics, practitioners, policy-makers, knowledge brokers and a funder. RESULTS: The findings suggest that stakeholders had positive experiences when engaged meaningfully in the research process, where research projects were carefully planned and managed with attention to context and culture, and where the research team was effective, respectful and communicative. These factors help to facilitate the translation of research into policy and practice. However, multiple challenges of collaborative research were identified which related to structural and systemic challenges, building and maintaining relationships, use and collection of data and information, cultural perceptions of research and research generation, and getting evidence into action. Participants felt that changing the funding system, exploring more collaborative research methodologies, improved research translation, and more effective collaborative relationships at all stages of the research process could address some of these challenges. CONCLUSIONS: The findings highlight that, whilst stakeholder engagement in research was considered important, structural, cultural and individual practices impacted how this worked in practice. Identifying and testing solutions to address these challenges could improve synergies between research, policy, and practice and lead to the production of impactful research that reduces wastage of public funding, improves implementation of findings and ultimately improves public health outcomes.

ABSTRACT

BACKGROUND: Data are limited on the burden of influenza and seasonal influenza vaccine effectiveness (VE) in children with sickle cell disease (SCD). METHODS: We used a prospectively collected clinical registry of SCD patients 6 months to 21 years of age to determine the influenza cases per 100 patient-years, vaccination rates, and a test-negative case-control study design to estimate influenza VE against medically attended laboratory-confirmed influenza infection. Influenza-positive cases were randomly matched to test-negative controls on age and influenza season in 1:1 ratio. We used adjusted logistic regression models to compare odds ratio (OR) of vaccination in cases to controls. We calculated VE as [100% × (1 - adjusted OR)] and computed 95% confidence intervals (CIs) around the estimate. RESULTS: There were 1037 children with SCD who were tested for influenza, 307 children (29.6%) had at least one influenza infection (338 infections, incidence rate 3.7 per 100 person-years; 95% CI, 3.4-4.1) and 56.2% of those tested received annual influenza vaccine. Overall VE pooled over five seasons was 22.3% (95% CI, -7.3% to 43.7%). Adjusted VE estimates ranged from 39.7% (95% CI, -70.1% to 78.6%) in 2015/2016 to -5.9% (95% CI, -88.4% to 40.4%) in the 2016/17 seasons. Influenza VE varied by age and was highest in children 1-5 years of age (66.6%; 95% CI, 30.3-84.0). Adjusted VE against acute chest syndrome during influenza infection was 39.4% (95% CI, -113.0 to 82.8%). CONCLUSIONS: Influenza VE in patients with SCD varies by season and age. Multicenter prospective studies are needed to better establish and monitor influenza VE among children with SCD.

ABSTRACT

Since the COVID-19 pandemic first hit Wuhan, China, in December 2019, scientists have been racing to develop and test novel vaccines to protect against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The speed of scientific discovery related to COVID-19 is unprecedented. With several vaccine candidates already being tested in clinical trials, we pose the question: what will the vaccine hesitant do in the face of this pandemic?

ABSTRACT

We report a cluster of pediatric cryptosporidiosis infections among solid organ transplant recipients at a summer camp in Georgia, USA. A retrospective cohort study was conducted to investigate the risk factors for infection. A total of 118 campers attended the camp during July 23-28, 2017. The overall attack rate among campers during the outbreak was 11% (13/118). Sanger-based amplicon sequencing of stool specimens from 7 (80%) campers identified Cryptosporidium hominis as the suspected etiologic agent. All infected campers were heart or kidney transplant recipients receiving immunosuppressive therapy. The median reported symptom duration was 12 days (range 6-18 days) and 9 (69.2%) were hospitalized for at least one night (median length of stay 5 days, range 2-16 days). There were no deaths or acute rejection events attributed to infection. The results of the epidemiologic and environmental investigation suggest a recreational pool as the presumed source, although there was no direct evidence to support this. Many long-term interventions were implemented, and there have been no further outbreaks at the camp in the following two years. This outbreak demonstrates that cryptosporidiosis may be associated with notable burden in pediatric transplant recipients, and illustrates the challenges associated with source identification and containment.

ABSTRACT

Homelessness adversely affects an individual's ability to access healthcare, opportunities for social interaction and recreational activities such as physical activity. This study aimed to evaluate the impact of a community-based physical activity and peer support intervention on the health and wellbeing of homeless participants. This study employed semi-structured interviews to investigate the perceived impact of the Street Fit Scotland intervention on the health and wellbeing of 10 homeless adults. Interviews were audio recorded and transcribed verbatim. A thematic analysis was conducted. Participants reported that their health and wellbeing had improved since attending the intervention. This was attributed to improvements in self-esteem, social interaction and mental wellbeing. Participants generally felt that their physical activity had increased since attending Street Fit Scotland, and a number of individuals reported that they were making healthier choices with regards to health behaviors. A theory of change logic model was developed that demonstrated how each component of the intervention influences the observed and intended outcomes. Attendance of Street Fit Scotland had positive effects on participant's health and wellbeing, particularly concerning self-esteem, health behaviors, social interaction, and physical activity. More efforts should be made to evaluate small-scale interventions that are reaching vulnerable population groups.
