OBJECTIVE: Despite the implementation of a short-term direct observation treatment programme, HIV coinfection is one of the main determinants of tuberculosis (TB) treatment success. This meta-analysis was conducted to report the impact of HIV on TB treatment outcomes using inconsistent and variable study findings.
METHODS: Systematic review and meta-analysis was performed.
METHODS: The PubMed/Medline, Web of Science and Google Scholar databases were used to access the articles. The Joanna Briggs Institute (JBI) Meta-Analysis of Statistics Assessment and Review Instrument was used for the critical appraisal.
METHODS: All observational studies conducted in Ethiopia and reporting TB treatment outcomes in relation to HIV coinfection were included in the final analysis.
METHODS: Two independent reviewers extracted the data using a standardised data extraction format. The JBI critical appraisal tool was used to assess the quality of primary studies. Stata V.14 was used for the data analysis. Cochran\'s Q statistic with inverse variance (I2) and funnel plot are used to assess the presence of heterogeneity (I2=94.4%, p<0.001) and publication bias, respectively. A random effect model was used to estimate TB treatment outcomes with a 95% CI.
RESULTS: The overall success rate of TB treatment was 69.9% (95% CI 64% to 75%). The cure rate of TB among patients living with HIV was 19.3%. Furthermore, the odds of unsuccessful treatment among TB-HIV coinfected patients were 2.6 times greater than those among HIV nonreactive patients (OR 2.65; 95% CI 2.1 to 3.3).
CONCLUSIONS: The success of TB treatment among patients living with HIV in Ethiopia was lower than the WHO standard threshold (85%). HIV coinfection hurts TB treatment success. Therefore, collaborative measurements and management, such as early treatment initiation, follow-up and the management of complications, are important.

OBJECTIVE: To assess healthcare workers\' (HCWs) confidence level in diagnosing and managing mpox disease and its associated factors in hospitals in the Amhara Region.
METHODS: Institution-based cross-sectional study.
METHODS: Hospitals in the Amhara Region, Northwest Ethiopia.
METHODS: A total of 640 HCWs, with a response rate of 96.9%, participated from 1 October to 30 December 2022. A multistage stratified random sampling technique with proportional allocation was used to recruit study participants. Data were collected using the KoboCollect toolbox and exported to STATA V.17 for analysis. Descriptive statistics were used to describe data. Ordinal logistic regression analysis was used to identify predictors of confidence level to diagnose and manage mpox at p<0.05.
METHODS: HCWs\' confidence level in diagnosing and managing mpox disease and its associated factors.
RESULTS: The overall proportion of HCWs who had high confidence level in diagnosing and managing mpox disease was found to be 31.5% (95% CI: 27.9%, 35.2%). Similarly, 26.8% (95% CI: 23.2%, 30.3%) and 41.8% (95% CI: 38.1%, 45.4%) of HCWs expressed medium and low confidence level to diagnose and manage the disease, respectively. The odds of higher confidence versus lower or medium confidence level in diagnosing and managing mpox were greater for HCWs who regularly visit amenable websites (adjusted OR (AOR)=1.59, 95% CI: 1.16, 2.2), were physicians (AOR=1.9, 95% CI: 1.32, 2.73), were aged 30-35 years old (AOR=1.64, 95% CI: 1.12, 2.39), had got public health emergency epidemic disease management training (AOR=2.8, 95% CI: 1.94, 4.04) and had positive attitudes (AOR=1.72, 95% CI: 1.26, 2.36) compared with their counterparts.
CONCLUSIONS: The overall confidence level of HCWs in diagnosing and managing mpox disease in the study area was low. Therefore, the HCWs should be regularly updated about mpox disease through morning sessions and training in the diagnosis and clinical management of mpox disease including infection prevention and control.

Granulicatella adiacens is a gram-positive coccus that is normally found in the human oral cavity and gastrointestinal and urogenital tracts but can rarely cause infection. When it does cause infection, Granulicatella adiacens has been most associated with bacteremia and endovascular infection, but to our knowledge, there are no previously documented cases of arteriovenous graft (AVG) infection. We present a case of Granulicatella adiacens bacteremia with associated AVG infection.

BACKGROUND: Despite universal access to government-funded direct-acting antivirals (DAAs) in 2016, the rate of hepatitis C treatment uptake in Australia has declined substantially. Most hepatitis C is related to injecting drug use; reducing the hepatitis C burden among people who inject drugs (PWID) is, therefore, paramount to reach hepatitis C elimination targets. Increasing DAA uptake by PWID is important for interrupting transmission and reducing incidence, as well as reducing morbidity and mortality and improving quality of life of PWID and meeting Australia\'s hepatitis C elimination targets.
METHODS: A cluster randomised cross-over trial will be conducted with three intervention arms and a control arm. Arm A will receive rapid hepatitis C virus (HCV) antibody testing; arm B will receive rapid HCV antibody and rapid RNA testing; arm C will receive rapid HCV antibody testing and same-day treatment initiation for HCV antibody-positive participants; the control arm will receive standard of care. The primary outcomes will be (a) the proportion of participants with HCV commencing treatment and (b) the proportion of participants with HCV achieving cure. Analyses will be conducted on an intention-to-treat basis with mixed-effects logistic regression models.
BACKGROUND: The study has been approved by the Alfred Ethics Committee (number HREC/64731/Alfred-2020-217547). Each participant will provide written informed consent. Reportable adverse events will be reported to the reviewing ethics committee. The findings will be presented at scientific conferences and published in peer-reviewed journals.
BACKGROUND: NCT05016609.
UNASSIGNED: The study commenced recruitment on 9 March 2022 and is expected to complete recruitment in December 2024.

OBJECTIVE: The objective of the study was to assess the clinical predictive value of the dynamics of absolute lymphocyte count (ALC) for 90-day all-cause mortality in sepsis patients in intensive care unit (ICU).
METHODS: Retrospective cohort study using big data.
METHODS: This study was conducted using the Medical Information Mart for Intensive Care IV database V.2.0 database.
METHODS: The primary outcome was 90-day all-cause mortality.
METHODS: Patients were included if they were diagnosed with sepsis on the first day of ICU admission. Exclusion criteria were ICU stay under 24 hours; the absence of lymphocyte count on the first day; extremely high lymphocyte count (>10×109/L); history of haematolymphatic tumours, bone marrow or solid organ transplants; survival time under 72 hours and previous ICU admissions. The analysis ultimately included 17 329 sepsis patients.
RESULTS: The ALC in the non-survivors group was lower on days 1, 3, 5 and 7 after admission (p<0.001). The ALC on day 7 had the highest area under the curve (AUC) value for predicting 90-day mortality. The cut-off value of ALC on day 7 was 1.0×109/L. In the restricted cubic spline plot, after multivariate adjustments, patients with higher lymphocyte counts had a better prognosis. After correction, in the subgroups with Sequential Organ Failure Assessment score ≥6 or age ≥60 years, ALC on day 7 had the lowest HR value (0.79 and 0.81, respectively). On the training and testing set, adding the ALC on day 7 improved all prediction models\' AUC and average precision values.
CONCLUSIONS: Dynamic changes of ALC are closely associated with 90-day all-cause mortality in sepsis patients. Furthermore, the ALC on day 7 after admission is a better independent predictor of 90-day mortality in sepsis patients, especially in severely ill or young sepsis patients.

A woman in her 40s known to have systemic lupus erythematosus presented with a maculopapular rash on her face, neck and chest following measles exposure. She had received a single-dose measles vaccine as a child in the 1970s and was therefore presumed to be immune, and thus not infectious. As a result, she was initially managed in an open bay. Measles virus IgM antibody in serum was undetectable; however, measles virus RNA was subsequently detected in throat swab by PCR, which is consistent with current infection. Measles is one of the most transmissible diseases in the world and cases are rising both in the UK and globally. Our case and literature review highlight the risk of vaccine failure in measles, especially in people who have not received two doses of the measles, mumps and rubella vaccine. It also highlights the challenges in diagnosing measles in previously vaccinated individuals.

Nanomaterials are becoming important tools for vaccine development owing to their tunable and adaptable nature. Unique properties of nanomaterials afford opportunities to modulate trafficking through various tissues, complement or augment adjuvant activities, and specify antigen valency and display. This versatility has enabled recent work designing nanomaterial vaccines for a broad range of diseases, including cancer, inflammatory diseases, and various infectious diseases. Recent successes of nanoparticle vaccines during the coronavirus disease 2019 (COVID-19) pandemic have fueled enthusiasm further. In this review, the most recent developments in nanovaccines for infectious disease, cancer, inflammatory diseases, allergic diseases, and nanoadjuvants are summarized. Additionally, challenges and opportunities for clinical translation of this unique class of materials are discussed.

Coinfection of Pseudomonas and Aspergillus has not been previously reported in patients with chronic obstructive pulmonary disease (COPD). A middle-aged, thinly built woman (Body Mass Index: 18.1 kg/m²) who smokes bidi (a type of tobacco) and has a history of exposure to open log fires for cooking, has been suffering from COPD for the last 4 years. She has been taking inhaled betamethasone and tiotropium. Additionally, she had uncontrolled diabetes for a few months. She presented with fever, productive cough, shortness of breath and chest pain for 5 days. She required non-invasive ventilation support for type-2 respiratory failure. Chest X-ray and CT confirmed pneumonia, cavities and abscesses in both lungs. Repeated sputum and bronchoalveolar lavage confirmed coinfections with Pseudomonas aeruginosa and Aspergillus fumigatus, respectively. Along with supportive therapy, she was treated with tablet levofloxacin and injection amikacin for 6 weeks based on culture sensitivity reports, and capsule itraconazole for 6 months. She recovered completely to her baseline COPD and diabetes status. This case study confirms that coinfections can occur in COPD and diabetes, highlighting the need for clinicians to be vigilant for the possibility of such symbiotic coinfections.

BACKGROUND: Critically ill patients are at risk of suboptimal beta-lactam antibiotic (beta-lactam) exposure due to the impact of altered physiology on pharmacokinetics. Suboptimal concentrations can lead to treatment failure or toxicity. Therapeutic drug monitoring (TDM) involves adjusting doses based on measured plasma concentrations and individualising dosing to improve the likelihood of improving exposure. Despite its potential benefits, its adoption has been slow, and data on implementation, dose adaptation and safety are sparse. The aim of this trial is to assess the feasibility and fidelity of implementing beta-lactam TDM-guided dosing in the intensive care unit setting.
METHODS: A beta-lactam antibiotic Dose AdaPtation feasibility randomised controlled Trial using Therapeutic Drug Monitoring (ADAPT-TDM) is a single-centre, unblinded, feasibility randomised controlled trial aiming to enroll up to 60 critically ill adult participants (≥18 years). TDM and dose adjustment will be performed daily in the intervention group; the standard of care group will undergo plasma sampling, but no dose adjustment. The main outcomes include: (1) feasibility of recruitment, defined as the number of participants who are recruited from a pool of eligible participants, and (2) fidelity of TDM, defined as the degree to which TDM as a test is delivered as intended, from accurate sample collection, sample processing to result availability. Secondary outcomes include target attainment, uptake of TDM-guided dosing and incidence of neurotoxicity, hepatotoxicity and nephrotoxicity.
BACKGROUND: This study has been approved by the Alfred Hospital human research ethics committee, Office of Ethics and Research Governance (reference: Project No. 565/22; date of approval: 22/11/2022). Prospective consent will be obtained and the study will be conducted in accordance with the Declaration of Helsinki. The finalised manuscript, including aggregate data, will be submitted for publication in a peer reviewed journal. ADAPT-TDM will determine whether beta-lactam TDM-guided dose adaptation is reproducible and feasible and provide important information required to implement this intervention in a phase III trial.
