RESUMO
BACKGROUND: Before April 2022, monkeypox virus infection in humans was seldom reported outside African regions where it is endemic. Currently, cases are occurring worldwide. Transmission, risk factors, clinical presentation, and outcomes of infection are poorly defined. METHODS: We formed an international collaborative group of clinicians who contributed to an international case series to describe the presentation, clinical course, and outcomes of polymerase-chain-reaction-confirmed monkeypox virus infections. RESULTS: We report 528 infections diagnosed between April 27 and June 24, 2022, at 43 sites in 16 countries. Overall, 98% of the persons with infection were gay or bisexual men, 75% were White, and 41% had human immunodeficiency virus infection; the median age was 38 years. Transmission was suspected to have occurred through sexual activity in 95% of the persons with infection. In this case series, 95% of the persons presented with a rash (with 64% having ≤10 lesions), 73% had anogenital lesions, and 41% had mucosal lesions (with 54 having a single genital lesion). Common systemic features preceding the rash included fever (62%), lethargy (41%), myalgia (31%), and headache (27%); lymphadenopathy was also common (reported in 56%). Concomitant sexually transmitted infections were reported in 109 of 377 persons (29%) who were tested. Among the 23 persons with a clear exposure history, the median incubation period was 7 days (range, 3 to 20). Monkeypox virus DNA was detected in 29 of the 32 persons in whom seminal fluid was analyzed. Antiviral treatment was given to 5% of the persons overall, and 70 (13%) were hospitalized; the reasons for hospitalization were pain management, mostly for severe anorectal pain (21 persons); soft-tissue superinfection (18); pharyngitis limiting oral intake (5); eye lesions (2); acute kidney injury (2); myocarditis (2); and infection-control purposes (13). No deaths were reported. CONCLUSIONS: In this case series, monkeypox manifested with a variety of dermatologic and systemic clinical findings. The simultaneous identification of cases outside areas where monkeypox has traditionally been endemic highlights the need for rapid identification and diagnosis of cases to contain further community spread.

This study aims to understand the impact of early antiretroviral therapy (ART) on HIV-specific T-cell responses measured after treatment interruption may inform strategies to deliver ART-free immune-mediated viral suppression. HIV-specific T-cell immunity was analysed using gamma interferon enzyme-linked immunospot assays in two studies. SPARTAC included individuals with primary HIV infection randomised to 48 weeks of ART (n = 24) or no immediate therapy (n = 37). The PITCH (n = 7) cohort started antiretroviral therapy in primary infection for at least one year, followed by TI. In SPARTAC, participants treated in PHI for 48 weeks followed by TI for 12 weeks, and those who remained untreated for 60 weeks made similar HIV Gag-directed responses (both magnitude and breadth) at week 60. However, the treated group made a greater proportion of novel HIV Gag-directed responses by Week 60, suggestive of a greater reserve to produce new potentially protective responses. In the more intensively followed PITCH study, 6/7 participants showed dominant Gag and/or Pol-specific responses post-TI compared with pre-TI. Although early ART in PHI was not associated with major differences in HIV-specific immunity following TI compared with untreated participants, the potential to make more new Gag-directed responses warrants further investigation as this may inform strategies to achieve ART-free control.
RESUMO
BACKGROUND: The COVID-19 pandemic prompted an unprecedented surge in virtual services, necessitating a rapid shift to digital healthcare approaches. This review focuses on evaluating the evidence of virtual care (VC) in delivering HIV care, considering the complex nature of HIV and the need for tailored-approaches, especially for marginalized populations. METHODS: A mixed-methods systematic review was performed with searches on five databases, covering studies from January 1946 to May 2022. Inclusion criteria involved two-way virtual consultations between healthcare workers and people living with HIV (PLHIV), with detailed descriptions and outcomes. Qualitative and quantitative studies were included, and the risk of bias was assessed using the Newcastle-Ottawa score and Stenfors' framework. RESULTS: Among 4143 identified records, 26 studies met the criteria, with various models of care described. The majority of studies were observational, and videoconferencing was the primary mode of virtual consultation employed. Quantitative analysis revealed PLHIV generally accept VC, with high attendance rates (87%). Mean acceptability and satisfaction rates were 80% and 85%, respectively, while 87% achieved HIV viral suppression. The setting and models of VC implementation varied, with some introduced in response to COVID-19 while others were as part of trials. CONCLUSIONS: VC for PLHIV is deemed an acceptable and effective approach and is associated with good virological outcomes. Data on other health outcomes is lacking. The review underscores the importance of diverse models of care, patient choice and comprehensive training initiatives for both staff and patients. Establishing a 'gold standard' for VC models is crucial for ensuring appropriate and effective reviews of PLHIV in virtual settings.
RESUMO
Persistent inflammation is described in people with HIV (PWH) on antiretroviral treatment (ART). Early ART initiation is associated with reduced inflammation. We aimed to evaluate neuroinflammation, using translocator protein (TSPO) [11C]PBR28 PET neuroimaging in PWH who initiated ART during acute HIV (aPWH) versus chronic HIV infection (cPWH) versus a control population. This was a cross-sectional, observational study. All participants underwent [11C]PBR28 PET-CT neuroimaging. Using a two-tissue compartment model, total volume of distribution (VT) and distribution volume ratios (DVR) using cortical grey matter as a pseudo-reference region at 20 regions of interest (ROIs) were calculated. Differences in VT and DVR were compared between groups using the Kruskall-Wallis test. Seventeen neuro-asymptomatic male PWH on ART (9 aPWH, 8 cPWH) and 8 male control participants (CPs) were included. Median (interquartile range, IQR) age was 40 (30, 46), 44 (41, 47) and 21 (20, 25) years in aPWH, cPWH and CPs, respectively. Median (IQR) CD4 (cells/µL) and CD4:CD8 were 687 (652, 1014) and 1.37 (1.24, 1.42), and 700 (500, 720) and 0.67 (0.64, 0.82) in aPWH and cPWH, respectively. Overall, no significant difference in VT and DVR were observed between the three groups at any ROIs. cPWH demonstrated a trend towards higher mean VT compared with aPWH and CPs at most ROIs. No significant differences in neuroinflammation, using [11C]PBR28 binding as a proxy, were identified between cPWH, aPWH and CPs. A trend towards lower absolute [11C]PBR28 binding was seen amongst aPWH and CPs, suggesting early ART may mitigate neuroinflammation.

BACKGROUND: Between May and November, 2022, global outbreaks of human monkeypox virus infection have been reported in more than 78 000 people worldwide, predominantly in men who have sex with men. We describe the epidemiological and clinical characteristics of monkeypox virus infection in cisgender (cis) and transgender (trans) women and non-binary individuals assigned female sex at birth to improve identification and understanding of risk factors. METHODS: International collaborators in geographical locations with high numbers of diagnoses of monkeypox virus infection were approached and invited to contribute data on women and non-binary individuals with confirmed monkeypox virus infection. Contributing centres completed deidentified structured case-report spreadsheets, adapted and developed by participating clinicians, to include variables of interest relevant to women and non-binary individuals assigned female at birth. We describe the epidemiology and clinical course observed in the reported infections. FINDINGS: Collaborators reported data for a total of 136 individuals with monkeypox virus infection who presented between May 11 and Oct 4, 2022, across 15 countries. Overall median age was 34 years (IQR 28-40; range 19-84). The cohort comprised 62 trans women, 69 cis women, and five non-binary individuals (who were, because of small numbers, grouped with cis women to form a category of people assigned female at birth for the purpose of comparison). 121 (89%) of 136 individuals reported sex with men. 37 (27%) of all individuals were living with HIV, with a higher proportion among trans women (31 [50%] of 62) than among cis women and non-binary individuals (six [8%] of 74). Sexual transmission was suspected in 55 (89%) trans women (with the remainder having an unknown route of transmission) and 45 (61%) cis women and non-binary individuals; non-sexual routes of transmission (including household and occupational exposures) were reported only in cis women and non-binary individuals. 25 (34%) of 74 cis women and non-binary individuals submitted to the case series were initially misdiagnosed. Overall, among individuals with available data, rash was described in 124 (93%) of 134 individuals and described as anogenital in 95 (74%) of 129 and as vesiculopustular in 105 (87%) of 121. Median number of lesions was ten (IQR 5-24; range 1-200). Mucosal lesions involving the vagina, anus, or oropharynx or eye occurred in 65 (55%) of 119 individuals with available data. Vaginal and anal sex were associated with lesions at those sites. Monkeypox virus DNA was detected by PCR from vaginal swab samples in all 14 samples tested. 17 (13%) individuals were hospitalised, predominantly for bacterial superinfection of lesions and pain management. 33 (24%) individuals were treated with tecovirimat and six (4%) received post-exposure vaccinations. No deaths were reported. INTERPRETATION: The clinical features of monkeypox in women and non-binary individuals were similar to those described in men, including the presence of anal and genital lesions with prominent mucosal involvement. Anatomically, anogenital lesions were reflective of sexual practices: vulvovaginal lesions predominated in cis women and non-binary individuals and anorectal features predominated in trans women. The prevalence of HIV co-infection in the cohort was high. FUNDING: None.

PURPOSE OF REVIEW: The COVID-19 pandemic and public health response have directly and indirectly affected broader health outcomes, especially for those with existing chronic conditions, including HIV. We examine our current understanding of the global impact of COVID-19 on people with HIV (PWH). RECENT FINDINGS: The interaction between COVID-19 and HIV is complex, making it challenging to estimate its true impact on PWH. Evidence to date does not suggest that HIV confers a higher risk of acquiring SARS-CoV-2. However, once acquired, HIV increases the risk of severe COVID-19 and mortality, particularly in immunosuppressed viraemic individuals and in the context of traditional COVID-19 risk factors, including disparities in social determinants of health. In addition, COVID-19 vaccines may be less effective in the context of HIV infection with additional doses needed. The consequences of disruption of access to essential prevention and treatment services because of the pandemic are becoming evident and will likely adversely affect outcomes, risking decades of progress. SUMMARY: Given the increased mortality risk and reduced vaccine effectiveness seen in PWH, specific prevention and support measures are needed, including prioritization of vaccination and boosters, funding to mitigate the impact of pandemic and enabling integrated healthcare delivery during pandemics will be critical.

OBJECTIVES: Our objective was to examine the public response to public health and media messaging during the human monkeypox virus (MPXV) outbreak in the UK, focusing on at-risk communities. METHODS: A co-produced, cross-sectional survey was administered in June and July 2022 using community social media channels and the Grindr dating app. Basic descriptive statistics, logistic regression, and odds ratio p values are presented. RESULTS: Of 1932 survey respondents, 1750 identified as men, 88 as women, and 64 as gender non-conforming. Sexual identity was described as gay/lesbian/queer (80%), bisexual (12%), heterosexual (4%), and pansexual (2%); 39% were aged <40 years; 71% self-identified as White, 3% as Black, 8% as Asian, 2%as LatinX, and 11% as 'Mixed or Other' heritage groups. In total, 85% were employed and 79% had completed higher education. A total of 7% of respondents identified themselves as living with HIV. Overall, 34% reported limited understanding of public health information, 52% considered themselves at risk, 61% agreed that people with MPXV should isolate for 21 days, 49% reported they would first attend a sexual health clinic if symptomatic, 86% reported they would accept a vaccine, and 59% believed that MPXV originated from animals. The most trusted sources of information were healthcare professionals (37%), official health agencies (29%), and mainstream media (12%). CONCLUSIONS: Vaccine acceptability was very high, yet the understanding and acceptance of public health information varied. Social determinants of health inequalities already shaping the UK landscape risk were compounded in this new emergency. Engagement with structurally disadvantaged members of affected communities and better dissemination of public health messaging by trusted healthcare professionals are essential for the public health response.

OBJECTIVES: We aimed to explore the experiences of people who initiated rapid antiretroviral therapy (ART) within 7 days of HIV diagnosis, as part of routine care in London. METHODS: Using purposive sampling, 18 in-depth, semistructured interviews were conducted between December 2020 and September 2021 with people who started rapid ART at Barts Health NHS Trust. Participants aged 22-69 years included 15 cisgender men and three cisgender women. Five identified as heterosexual and 13 as gay and bisexual and other men who have sex with men. Ethnic identities: six White Non-UK, five White UK, three Black Caribbean, two South Asian and two East Asian. Interviews explored feelings about the new HIV diagnosis, attitudes to rapid ART including barriers to and facilitators of starting. Thematic analysis of transcribed interviews was undertaken. RESULTS: Four themes were identified: (1) being offered rapid ART is acceptable; (2) it is a way of taking control of their health; (3) the need for information and support and (4) an individualised approach to care. Reasons for starting included getting well, staying well and reducing the likelihood of passing on HIV. Facilitators included being given comprehensive information about treatment and managing potential side-effects and a supportive clinical team. Support specified included a non-judgemental attitude, approachability, reassurance, encouragement and information about peer support. Most participants expressed they could not understand why people would not begin treatment, but suggested needing more time to decide and denial of diagnosis as possible barriers. CONCLUSIONS: To our knowledge, this is the first qualitative study exploring the experiences of people initiating rapid ART in the UK. It was deemed acceptable to an ethnically diverse, predominantly male sample of people newly diagnosed with HIV. Future research should include strategies to recruit a more gender diverse sample and those who declined or stopped rapid ART.

OBJECTIVES: Disruption to sexual health services during the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2; coronavirus disease 2019 [COVID-19]) pandemic may have adversely affected the provision of HIV post-exposure prophylaxis (PEP), possibly leading to increased HIV transmission. Globally, services have reported a reduction in the number of PEP prescriptions dispensed during lockdowns, although it is unclear why. Our primary objective was to describe the temporal change in weekly HIV PEP dispensed at six English sexual health clinics in 2020. METHODS: We performed a cross-sectional review of PEP prescriptions from six English centres during 2020. RESULTS: During 2020, 2884 PEP prescriptions were dispensed across the six centres studied, a fall of 34.5% from the 4403 PEP prescriptions in 2019. Before the COVID-related lockdown in 2020, the PEP dispensed was stable at 82.5 per week. Following the first lockdown, this fell to a nadir of 13 in week 14 (Figure 1). Prescriptions rose to a peak of 79 in week 37 and then declined to 32 prescriptions in the last week of 2020. There was no difference in the following characteristics of PEP recipients before and during the first lockdown: age, ethnicity, country of birth or the service the recipient attended. CONCLUSION: Whatever the reason for the fall in PEP seen in England over 2020, it is essential that HIV testing and access to HIV prevention is maintained for those in need.

BACKGROUND: The contribution of HIV to COVID-19 outcomes in hospitalized inpatients remains unclear. We conducted a multi-centre, retrospective matched cohort study of SARS-CoV-2 PCR-positive hospital inpatients analysed by HIV status. METHODS: HIV-negative patients were matched to people living with HIV (PLWH) admitted from 1 February 2020 to 31 May 2020 up to a 3:1 ratio by the following: hospital site, SARS-CoV-2 test date ± 7 days, age ± 5 years, gender, and index of multiple deprivation decile ± 1. The primary objective was clinical improvement (two-point improvement or better on a seven-point ordinal scale) or hospital discharge by day 28, whichever was earlier. RESULTS: A total of 68 PLWH and 181 HIV-negative comparators were included. In unadjusted analyses, PLWH had a reduced hazard of achieving clinical improvement or discharge [adjusted hazard ratio (aHR) = 0.57, 95% confidence interval (CI): 0.39-0.85, p = 0.005], but this association was ameliorated (aHR = 0.70, 95% CI: 0.43-1.17, p = 0.18) after additional adjustment for ethnicity, frailty, baseline hypoxaemia, duration of symptoms prior to baseline, body mass index (BMI) categories and comorbidities. Baseline frailty (aHR = 0.79, 95% CI: 0.65-0.95, p = 0.011), malignancy (aHR = 0.37, 95% CI 0.17, 0.82, p = 0.014) remained associated with poorer outcomes. The PLWH were more likely to be of black, Asian and minority ethnic background (75.0% vs 48.6%, p = 0.0002), higher median clinical frailty score [3 × interquartile range (IQR): 2-5 vs, 2 × IQR: 1-4, p = 0.0069), and to have a non-significantly higher proportion of active malignancy (14.4% vs 9.9%, p = 0.29). CONCLUSIONS: Adjusting for confounding comorbidities and demographics in a matched cohort ameliorated differences in outcomes of PLWH hospitalized with COVID-19, highlighting the importance of an appropriate comparison group when assessing outcomes of PLWH hospitalized with COVID-19.

OBJECTIVES: HIV outcomes centre primarily around clinical markers with limited focus on patient-reported outcomes. With a global trend towards capturing the outcomes that matter most to patients, there is agreement that standardizing the definition of value in HIV care is key to their incorporation. This study aims to address the lack of routine, standardized data in HIV care. METHODS: An international working group (WG) of 37 experts and patients, and a steering group (SG) of 18 experts were convened from 14 countries. The project team (PT) identified outcomes by conducting a literature review, screening 1979 articles and reviewing the full texts of 547 of these articles. Semi-structured interviews and advisory groups were performed with the WG, SG and people living with HIV to add to the list of potentially relevant outcomes. The WG voted via a modified Delphi process - informed by six Zoom calls - to establish a core set of outcomes for use in clinical practice. RESULTS: From 156 identified outcomes, consensus was reached to include three patient-reported outcomes, four clinician-reported measures and one administratively reported outcome; standardized measures were included. The WG also reached agreement to measure 22 risk-adjustment variables. This outcome set can be applied to any person living with HIV aged > 18 years. CONCLUSIONS: Adoption of the HIV360 outcome set will enable healthcare providers to record, compare and integrate standardized metrics across treatment sites to drive quality improvement in HIV care.

BACKGROUND: Antiretroviral therapy (ART) cannot cure HIV infection because of a persistent reservoir of latently infected cells. Approaches that force HIV transcription from these cells, making them susceptible to killing-termed kick and kill regimens-have been explored as a strategy towards an HIV cure. RIVER is the first randomised trial to determine the effect of ART-only versus ART plus kick and kill on markers of the HIV reservoir. METHODS: This phase 2, open-label, multicentre, randomised, controlled trial was undertaken at six clinical sites in the UK. Patients aged 18-60 years who were confirmed as HIV-positive within a maximum of the past 6 months and started ART within 1 month from confirmed diagnosis were randomly assigned by a computer generated randomisation list to receive ART-only (control) or ART plus the histone deacetylase inhibitor vorinostat (the kick) and replication-deficient viral vector T-cell inducing vaccines encoding conserved HIV sequences ChAdV63. HIVconsv-prime and MVA.HIVconsv-boost (the kill; ARTâ+âVâ+âV; intervention). The primary endpoint was total HIV DNA isolated from peripheral blood CD4+ T-cells at weeks 16 and 18 after randomisation. Analysis was by intention to treat. This trial is registered with ClinicalTrials.gov, NCT02336074. FINDINGS: Between June 14, 2015 and Jul 11, 2017, 60 men with HIV were randomly assigned to receive either an ART-only (n=30) or an ARTâ+âVâ+âV (n=30) regimen; all 60 participants completed the study, with no loss-to-follow-up. Mean total HIV DNA at weeks 16 and 18 after randomisation was 3·02 log10 copies HIV DNA per 106 CD4+ T-cells in the ART-only group versus 3·06 log10 copies HIV DNA per 106 CD4+ T-cells in ARTâ+âVâ+âV group, with no statistically significant difference between the two groups (mean difference of 0·04 log10 copies HIV DNA per 106 CD4+ T-cells [95% CI -0·03 to 0·11; p=0·26]). There were no intervention-related serious adverse events. INTERPRETATION: This kick and kill approach conferred no significant benefit compared with ART alone on measures of the HIV reservoir. Although this does not disprove the efficacy kick and kill strategy, for future trials enhancement of both kick and kill agents will be required. FUNDING: Medical Research Council (MR/L00528X/1).

PURPOSE OF REVIEW: There has been significant development of long-acting injectable therapy for the management of HIV in recent years that has the potential to revolutionise HIV care as we know it. This review summarises the data and outlines the potential challenges in the field of long-acting antiretroviral therapy (ART). RECENT FINDINGS: In recent years, monthly and two monthly long-acting injectable ART in the form of cabotegravir and rilpivirine has shown safety and efficacy in large-scale phase 3 randomised control trials. Also, agents with novel mechanisms of action, such as Lenacapavir, have been tested in early-phase studies and are currently being tested in phase 2-3 clinical trials; if successful, this may allow six-monthly dosing schedules. SUMMARY: However, despite evidence that suggests that these therapies are efficacious and acceptable to patients, the challenge of integrating these agents into our current healthcare infrastructure and making these novel agents cost-effective and available to the populations most likely to benefit remains. The next frontier for long-acting therapy will be to introduce these agents in a real-world setting ensuring that the groups most in need of long-acting therapy are not left behind.

Initiation of antiretroviral therapy (ART) in early compared with chronic human immunodeficiency virus (HIV) infection is associated with a smaller HIV reservoir. This longitudinal analysis of 60 individuals who began ART during primary HIV infection (PHI) investigates which pre- and posttherapy factors best predict HIV DNA levels (a correlate of reservoir size) after treatment initiation during PHI. The best predictor of HIV DNA at 1 year was pre-ART HIV DNA, which was in turn significantly associated with CD8 memory T-cell differentiation (effector memory, naive, and T-bet-Eomes- subsets), CD8 T-cell activation (CD38 expression) and T-cell immunoglobulin and mucin-domain containing-3 (Tim-3) expression on memory T cells. No associations were found for any immunological variables after 1 year of ART. Levels of HIV DNA are determined around the time of ART initiation in individuals treated during PHI. CD8 T-cell activation and memory expansion are linked to HIV DNA levels, suggesting the importance of the initial host-viral interplay in eventual reservoir size.

OBJECTIVES: To determine the incidence of 'burnout' among UK and Irish urological consultants and non-consultant hospital doctors (NCHDs). The second objective was to identify possible causative factors and to investigate the impact of various vocational stressors that urologists face in their day-to-day work and to establish whether these correlate with burnout. The third objective was to develop a new questionnaire to complement the Maslach Burnout Inventory (MBI), more specific to urologists as distinct from other surgical/medical specialties, and to use this in addition to the MBI to determine if there is a requirement to develop effective preventative measures for stress in the work place, and develop targeted remedial measures when individuals are affected by burnout. SUBJECTS AND METHODS: A joint collaboration was carried out between the Irish Society of Urology (ISU) and the British Association of Urological Surgeons (BAUS). Anonymous voluntary questionnaires were sent to all current registered members of both governing bodies. The questionnaire comprised two parts: the first part encompassed sociodemographic data collection and identifying potential risk factors for burnout, and the second used the MBI to objectively assess for workplace burnout. To evaluate differences in burnout, 2 × 2 contingency tables and Fischer's exact probability tests were used. RESULTS: In all, 575 urologists responded to the online survey out of a total of 1380 invites, yielding a 42% response rate. All respondents were aged <75 years (median age 45 years), with men representing 87.5% of respondents. In all, 75% of respondents worked in England, followed by the Republic of Ireland (9%), Scotland (8%), Northern Ireland (4%), and Wales (3%). In all, 79% of respondents were consultants, with 13% representing training posts, and 40% of respondents held a professorship/clinical lead position. Respondents' countries of origin included England, Scotland, Ireland, India, Wales, Malaysia, Pakistan and Sri Lanka. Overall, the mean emotion exhaustion (EE) score was 23.5, representing a moderate level of EE. The mean depersonalisation (DP) score was 8.2, representing a moderate level of DP. The mean personal achievement (PA) score was 17.1, representing high levels of PA. In all, 86 respondents (15%) reported self-medication with non-prescription drugs or alcohol to combat signs and symptoms of burnout, while 46 (8%) sought professional help for symptoms of burnout. In all, 460 respondents (80%) felt that burnout should be evaluated amongst members of the ISU/BAUS, and 345 (60%) would avail of counselling if provided. CONCLUSIONS: This is the first study to address the issue of burnout across two separate health systems in the UK and Ireland. This study has shown previously undescribed high levels of burnout characterised by EE and DP, with associated significant levels of self-medication amongst a male-predominant cohort. Burnout was attributed to non-surgical administrative/institutional factors, with most respondents reporting support for staff evaluation and the provision of counselling services. This pilot study lends itself to the creation of risk stratification for urologists, and an opportunity to provide educational resources, training/development programmes, and collegial and administrative support pathways.

BACKGROUND: The prevalence of urinary tract infections (UTIs) caused by extended-spectrum ß-lactamase (ESBL)-producing Enterobacteriaceae is increasing and the therapeutic options are limited, especially in primary care. Recent indications have suggested pivmecillinam to be a suitable option. This pilot study aimed to assess the viability of pivmecillinam as a therapeutic option in a Dublin cohort of mixed community and healthcare origin. METHODS: A prospective measurement of mean and fractional inhibitory concentrations of antibiotic use in 95 patients diagnosed with UTI caused by ESBL-producing Enterobacteriaceae was carried out. 36 % patients were from general practice, 40 % were admitted to hospital within south Dublin, and 25 % samples arose from nursing homes. EUCAST breakpoints were used to determine if an isolate was sensitive or resistant to antibiotic agents. RESULTS: Sixty-nine percent of patients (N = 66) with urinary ESBL isolates were female. The mean age of females was 66 years compared with a mean age of 74 years for males. Thirty-six percent of isolates originated from primary care, hospital inpatients (26 %), and nursing homes (24 %). The vast majority of ESBL isolates were E. coli (80 %). The E tests for mecillinam and co-amoxiclav had concentration ranges from 0.16 mg/L up to 256 mg/L. The mean inhibitory concentration (MIC) of mecillinam ranged from 0.25 to 256 mg/L, while co-amoxiclav MICs ranged from 6 to 256 mg/L. The percentage of isolates resistant to mecillinam and co-amoxiclav was found to be 5.26 and 94.74 % respectively. CONCLUSIONS: This is the first study exploring the use of pivmecillinam in an Irish cohort and has demonstrated that its use in conjunction with or without co-amoxiclav is an appropriate and useful treatment for urinary tract infections caused by ESBL-producing organisms.

PURPOSE OF REVIEW: To explore how ethical considerations, improved diagnostics and data from clinical trials might see the lowering of some of the barriers blocking a cure for HIV infection over the next 5 years. RECENT FINDINGS: Despite the recent well publicized but eventually disappointing case reports, there remains only one successful HIV cure, the 'Berlin patient'. We will review the data suggesting that more potent agents might achieve in-vivo viral activation and explore the tantalizing phenomenon of 'posttreatment control' following treatment in primary HIV infection. We will also explore how new assays and novel interventions might move the field forward. SUMMARY: There is a need for new agents that can be safely tested to impact the viral reservoir, a more meaningful understanding of how to assay patient samples, and research into mechanisms behind how the reservoir is established and impacted by therapy. With HIV+ve individuals responding so well to antiretroviral therapy, new trials must be tested hand-in-hand with guidance from patient representatives, especially with respect to determining the acceptable risk. The road to a cure is going to be difficult, but it is vital that inevitable disappointments do not detract from the final goal, which remains worth striving for.

PURPOSE: We investigated urethral diametric strain and threshold maximum inflation pressure for rupture during inadvertent inflation of a catheter anchoring balloon in the urethra. In addition, we evaluated a novel safety device to prevent trauma based on these parameters. MATERIALS AND METHODS: Inflation of a urethral catheter anchoring balloon was performed in the bulbar urethra of 21 ex vivo porcine models using 16Fr catheters. Urethral trauma was assessed with retrograde urethrography. Urethral rupture was correlated with internal urethral diametric strain and maximal urethral pressure threshold values in kPa. Urethral catheters were then inflated in the bulbar urethras of 7 fresh male cadavers using a standard syringe and a prototype syringe. The plunger of the standard syringe was depressed until opposing resistance pressure generated by the urethra prevented further inflation of the anchoring balloon. The plunger of the prototype safety syringe was depressed until sterile water in the syringe decanted through an activated safety threshold pressure valve. RESULTS: Retrograde urethrography demonstrated that porcine urethral rupture consistently occurred at an internal urethral diametric strain greater than 40% and a maximum inflation pressure greater than 150 kPa. The mean ± SD maximum human urethral threshold inflation pressure required to activate the safety prototype syringe pressure valve was 153 ± 3 kPa. In comparison, maximum inflation pressure was significantly greater using the standard syringe than the activated prototype syringe (mean 452 ± 188 kPa, p <0.001). CONCLUSIONS: Internal urethral diametric strain and threshold maximum inflation pressures are important parameters for designing a safer urethral catheter system with lower intrinsic threshold inflation pressures.
