Background: Cervical cancer (CC), mostly associated with high-risk human papillomaviruses (hrHPV) infection, is the most common cancer that disproportionately affects women in developing countries, including Ethiopia. Early detection of CC and initiation of treatment are key to positive health outcomes. Identifying factors associated with delayed CC diagnosis is essential for effective prevention and control efforts. This study assessed the stage at diagnosis and examined associated clinical and sociodemographic factors. Methods: An institution-based cross-sectional study was conducted among 284 women newly diagnosed with CC who attended Tibebe Ghion Specialized Hospital (TGSH) between 1st January 2021 and 31st December 2022. A structured questionnaire was used to collect data on the participants' demographic, reproductive, and gynaecologic history, and clinical profiles. The CC stage at diagnosis was categorised as early (stage I-IIA) or late (stage IIB-IV). Logistic regression models (unadjusted and adjusted) were used to examine associations of sociodemographic or clinical factors with stage at CC diagnosis. Results: The mean age ({+/-}standard deviation) at presentation was 53.2 {+/-} 11.3 years, with an age range of 18 - 80 years. Most of the patients (73.6%) were from rural areas, and three-fifths (58.1%) had no medical insurance. Among participants, 74.6% (95% CI: 69.4, 79.6%) had late-stage CC. The odds of late-stage CC diagnosis were higher for women from rural areas (AOR: 2.21; 95% CI:1.18, 4.12; p<0.013), and those with anaemia (defined as <12 mg/dl haemoglobin) (AOR: 3.42; 95% CI: 1.88, 6.23; p<0.001). On the other hand, the odds of late-stage CC diagnosis were lower in HIV positive women (AOR:0.41; 95%CI:0.19, 0.88; p<0.021). Conclusion: The proportion of late-stage diagnosis among CC patients was high. Residential area, anaemia status, and HIV serostatus were factors associated with stage at CC diagnosis. These findings can inform screening efforts of CC and call for expanding of the screening services to the rural setting in order to reduce the burden of late-stage CC diagnosis.

Background In Kenya, stroke is one of the top five causes of mortality, with a high rate of inpatient mortality. The American Heart Association (AHA) and American Stroke Association (ASA) translated scientific evidence into evidence-based clinical practice guidelines aimed at reducing inpatient mortality and improving the quality of care for stroke patients. Despite the proven benefits of the ASA stroke guidelines in improving stroke care, translation of the guidelines in various settings remains a key challenge. This study aimed to quantify the gap between evidence-based recommendations and current stroke care practices in a peri-urban referral facility in Kiambu, Kenya. The study was conducted at xxxxxxxxxx Hospital, a peri-urban referral facility in Kiambu County, Kenya. Methods: We reviewed records of stroke patients attending xxxxxxxxxxx from January 1, 2020, to December 31, 2023. The study evaluated acute stroke management practices and secondary prevention against the 2019 American Heart Association/American Stroke Association (AHA/ASA) Guidelines for the Early Management of Acute Ischemic Stroke. Results: The median distance travelled by stroke patients to the facility was 47.8 kilometres; further, the median onset-to-presentation time was 24 hours. The study evaluated eight clinical practices against the ASA guidelines. The facility lacked a dedicated stroke unit. Remarkably, patients arriving within the therapeutic window for intravenous alteplase and thrombectomy did not receive these treatments. Secondary prevention measures, including discharge on an antiplatelet regimen, were moderately adhered to; among the 86 eligible ischemic stroke patients, 67 (77.9%) were correctly discharged on aspirin. Similarly, 84/123 (68.3%) of the patients were discharged on statin therapy. Conclusion: Evidence-based stroke care recommendations were minimally adhered to at this peri-urban referral facility in Kiambu, Kenya. Contribution: This study quantifies the gap between evidence-based stroke care recommendations and current clinical practice in a peri-urban referral facility in Kenya, providing context-specific evidence to inform quality improvement initiatives and guideline implementation efforts in similar resource-constrained settings.

Abstract Background Health-related quality of life (HRQoL) is an important outcome in patients with chronic kidney disease (CKD) receiving kidney replacement therapy (KRT), but the relationship between comprehensive metabolic control and the Symptoms/Problems domain of kidney diseasespecific HRQoL remains uncertain. Objective To evaluate the association between composite metabolic control and the Symptoms/Problems domain of the Kidney Disease Quality of Life-36 (KDQOL-36) in patients with stage 5 CKD receiving KRT, and to explore the relationship between individual metabolic parameters and the continuous Symptoms/Problems score. Materials and Methods We conducted an observational, cross-sectional, analytical study of 177 adults receiving hemodialysis or peritoneal dialysis at a nephrology unit in Chihuahua, Mexico. Metabolic control included blood pressure, glycated hemoglobin (HbA1c), total cholesterol, and triglycerides. Adequate control was defined as achievement of at least three of four studydefined operational thresholds. The KDQOL-36 Symptoms/Problems score was analyze as a continuous variable and categorized as low, moderate, or high according to the study protocol. Group comparisons, Spearman correlations, Pearson chi-square tests, and ordinal logistic regression were performed. Results Adequate metabolic control was present in 106 patients (59.9%). No, statistically significant association was observed between achievement of at least three of four study-defined operational thresholds and Symptoms/Problems score category (x2=3.983; p=0.137; Cramers V=0.150). None of the individual metabolic parameters differed significantly across Symptoms/Problems score categories or showed significant correlations with the continuous score. In ordinal logistic regression, adequate metabolic control yielded an odds ratio of 1.81 (95% CI: 0.98-3.35; p=0.057) after adjustment for age, sex, time receiving KRT, and KRT modality. Conclusions No, statistically significant association was identified between the operational definition of metabolic control used in this study and the KDQOL-36 Symptoms/Problems domain in patients with stage 5 CKD receiving KRT. The findings support evaluating HRQoL multidimensionally and warrant confirmation in larger longitudinal studies.

Background/Aims: In medical practice, the rising prevalence of infections in kidney transplant recipients (KTRs) is a notable concern. However, understanding the incidence and risk factors associated with infections in KTRs remains limited. This study aims to assess the incidence and factors associated infection among KTRs. Additionally, we also investigate the median time of each infection among KTRs. Methods: A retrospective cohort study was conducted from 1 January 2018- 31 December 2022 at Thailand's tertiary hospital. We performed univariable and multivariable logistic regression analyses to identify potential risk factors related infection and investigated for the incidence and median time of each infection among KTRs. Results: A total of 179 participants were included in this study. Our findings reveal the kidney from living donor was protective factor for infection among KTRs (aOR 0.063, 95% CI 0.005-0.792; p = 0.032). Urinary tract infections (UTIs)showed as the predominant pathogenic manifestation among KTRs (43%). The median time of UTIs, cytomegalovirus (CMV) infection and pneumocystis pneumonia (PCP) were 16, 57 and 94.5 days, respectively. Conclusions: Our study establishes that receiving a kidney from a living donor is a protective factor against post-kidney transplant infections. Particularly urinary tract infections were most common of infection. Monitoring urinary tract infections post-transplantation is recommended. Moreover, awareness of UTI, CMV infection and PCP should be concerned during 2-3 months after transplantation. However, due to a small sample size; we recommend to increase the number of particular participants in further investigations.

Background: HIV and stroke are major contributors to disability in sub-Saharan Africa, yet their combined impact on cognitive and motor functioning remains poorly understood. Botswana has a high prevalence of HIV and rising stroke incidence, underscoring the need to characterize impairment to inform neurorehabilitation. Objective: To examine differences in cognitive performance, motor function, and activities of daily living between adults living with HIV only and those living with both HIV and stroke in Botswana. Methods: Thirty-three adults (19 HIV only; 14 HIV/ stroke) completed standardized cognitive (e.g. MoCA and Digit Symbol Coding [DSC]), and motor assessments (such as Box and Block Test [BBT], Grooved Pegboard [GPB], Grip Strength [GS], 10-Meter Walk Test [10MWT], Timed Up and Go [TUG]), and ADL measures (such as Barthel Index, Lawton IADL). Group comparisons used Wilcoxon rank-sum tests. Impairment was determined using both international z-score norms and Botswana-specific cutoffs from a prior cohort study. Results: Cognitive impairment was evident in both groups, but DSC z-scores were worse in the HIV/stroke vs HIV only group (median= -2.71 vs -1.34, p=0.015). Gross motor function showed deficits in the HIV/stroke group, including lower dominant-hand BBT performance (median z-score -2.79 vs. -1.75; p=0.008). Fine motor dexterity was markedly reduced in the HIV/stroke group, with GPB dominant-hand median z-scores of -4.26 vs. -1.40 (p=0.038) and non-dominant-hand impairment rates of 100% vs. 63.2% (p=0.043). Non-dominant GS was weaker in the HIV/stroke group (100% impaired vs. 47.4%; p=0.0014). Lower-limb performance was substantially worse, including TUG (median z-score -3.63 vs. 0.10; p=0.0001) and 10MWT (median z-score -5.36 vs. -2.47; p=0.0025). ADL scores were also lower in the HIV/stroke group compared to both Barthel and Lawton (p=0.002). Conclusions: HIV alone is associated with cognitive and motor impairment, with the addition of stroke producing significantly greater deficits across all motor domains. These findings demonstrate the need to integrate structured neurorehabilitation into HIV clinical care in Botswana.

Introduction: Acute gastroenteritis (AGE) is a global public health problem and a major cause of mortality in low- and lower-middle-income countries. Human bocavirus (HBoV) is among the viral agents associated with this condition. Therefore, investigating the presence of HBoV in cases of AGE in Salvador, Bahia, as well as its prevalence and circulating strains, is important. Objective: To investigate the occurrence of HBoV infection during an AGE outbreak in Salvador. Methods: A total of 178 samples were analyzed for HBoV using nested polymerase chain reaction (nested PCR), and the amplification products were visualized by agarose gel electrophoresis. HBoV was detected in 5.7% of the samples analyzed. Conclusion: This study contributes to the understanding of HBoV epidemiology as a secondary agent associated with acute gastroenteritis during a norovirus outbreak in Salvador. Continued investigation and identification of the etiological agents involved in outbreaks are essential for evaluating the causes of AGE. These findings also highlight the need for broader diagnostic approaches and the importance of phylogenetic analysis for monitoring and controlling viral infections.

Background. In the era of successful antiretroviral therapy (ART), mood disturbance remains highly prevalent in people with HIV (PWH). In the present study, we investigated the long-term legacy effects of long delay in ART initiation and low nadir CD4 count on mood symptoms in adults with HIV. The impacts of demographic and other HIV clinical factors were also examined. Methods. A total of 109 PWH (disease duration: 24.6{+/-}9.3 years) and 42 demographically matched healthy participants (people without HIV, or PWoH) participated in a cross-sectional study (41-70 years old (55.6{+/-}6.8), 62.9% African Americans, 27.2% female, 14.3{+/-}2.9 years of education). Mood symptoms were assessed with the Beck Depression Inventory-II (BDI-II) and the Profile of Mood States (POMS). A comprehensive neuropsychological test battery was administered to assess neurocognitive function. Results. Despite largely comparable neurocognitive performance between PWH and PWoH , PWH had worse mood symptoms than PWoH, including higher total BDI-II (p<.001) and total POMS scores (p=.002), as well as higher score in all POMS sub-scores (p<.007), except Vigor (p=.724). Within the PWH group, longer delays in ART initiation, lower nadir CD4 count, and lower educational attainment were associated with worse mood symptoms. By contrast, current plasma CD4+ cell count, plasma detectable viral load, and HIV disease duration were not associated with either BDI-II or POMS score. Conclusion. Mood disturbance is highly prevalent in PWH on ART. The long-term legacy effects of delay in ART initiation and low nadir CD4 count on mood management reinforce the necessity of early ART initiation in clinical practice.

Background: Stroke imposes substantial mortality and socioeconomic burden in India, particularly among younger adults. However, prospective evidence on the prognostic value of baseline clinical and radiomics features for mortality prediction remains limited. Objective: To assess mortality at 28, 90, 180, and 365 days after stroke; characterize survival patterns across stroke subtypes and vascular territories; and identify baseline demographic, clinical, and radiomics predictors of mortality. Methods: This prospective cohort study recruited consecutive patients with stroke admitted to a tertiary care hospital in Mangalore, India. Demographic, clinical, laboratory, and radiomics features were collected at admission, and mortality was assessed at 28, 90, 180, and 365 days. Kaplan Meier analysis was used to compare survival across stroke subtypes and vascular territories, while Cox proportional hazards regression was used to identify independent baseline predictors of mortality. Results: Among 63 confirmed stroke cases, 38 (60%) had ischemic stroke (IS) and 25 (40%) had haemorrhagic stroke (HS). Within the middle cerebral artery (MCA) territory, HS patients demonstrated better survival than IS patients due to a greater burden of adverse baseline characteristics such as previous stroke, atrial fibrillation, and higher lesion volume in the IS-MCA subgroup. The combined clinical-radiomics model demonstrated superior prognostic performance than individual models, with higher concordance indices and consistently lower Akaike Information Criterion values. In the combined model, stroke severity (aHR = 2.35, 3.0, 2.93, 2.41) and DWI texture heterogeneity of lesion (aHR = 2.35, 2.11, 2.24, 2.10) were the strongest predictors of mortality across all time points. The CT attenuation heterogeneity (aHR = 1.81, 28 days; 1.76, 90 days; 1.80, 180 days) of lesion and age (aHR = 1.48, 365 days) were also significant predictors. Conclusion: The radiomics features provide critical complementary information to clinical parameters for predicting 28-day mortality, unlike during mid- to long-term follow-up where their incremental contribution appears to be limited. Our results may have important implications in resource-constrained settings for supporting personalized post-stroke management and rehabilitation.

Stroke is a leading cause of mortality and disability in Uganda, with a prevalence of approximately 2.5% and a 25-30% 30-day mortality rate, exacerbated by limited access to predictive tools and advanced diagnostics. Machine learning (ML) offers potential for early stroke risk stratification, but its application in resource-constrained settings like Uganda requires tailored models and rigorous performance evaluation, as well as assessment of misclassification patterns. This study aimed to develop and internally validate an ML-based predictive model for stroke using clinical and socio-demographic characteristics among patients at Mulago National Referral Hospital (MNRH) and residents of Wakiso District, Uganda, identify key predictors and assess misclassification patterns to enhance targeted prevention. A retrospective case-control study utilized secondary data from 1,016 participants (254 stroke cases, 762 controls) across three prior studies conducted between 2006 and 2015. Eight ML algorithms were evaluated using 5-fold cross-validation, with performance metrics including accuracy, sensitivity, positive predictive value, F1-score, and area under receiver operator characteristics curve (AU-ROC). McNemars test compared model classification performance of the top 2 models. Feature importance identified key predictors, and misclassification patterns were analyzed using classification matrix and line graphs. The Random Forest (RF) model achieved the highest performance (95.18% accuracy, 90.10% F1-score, 97% AU-ROC). McNemars test confirmed RFs superior classification (p=0.01). Age, systolic blood pressure, total cholesterol, and waist-hip ratio were the top drivers of RF stroke predictions. RF misclassified 8.3% of stroke cases and 3.3% of non-stroke cases, due to overlaps in risk profiles (e.g., lower cholesterol, systolic blood pressure and age in false negatives). The RF model demonstrates strong potential for stroke risk prediction in Uganda, leveraging routine data to prioritize high-risk individuals. Misclassification analysis highlights areas for model refinement, supporting its potential for integration into clinical workflows for early intervention and stroke prevention in resource-limited settings. Future external validation across diverse populations is recommended.

Background and Objective: Adding belzutifan to adjuvant pembrolizumab improved disease-free survival (DFS) in LITESPARK-022, but its durability beyond the 1-year treatment is unknown. Methods: Following a registered plan, we reconstructed individual patient data from published Kaplan-Meier curves of ten phase 3 adjuvant renal cell carcinoma trials. Within each trial, we estimated restricted mean survival time differences ({Delta}RMST), hazard ratios (HRs) before and after planned treatment ended, and DFS differences. Key Findings and Limitations: In LITESPARK-022 (central review), the 24-month {Delta}RMST was 1.34 months (95% confidence interval 0.73-1.95), and the belzutifan arm remained ahead after month 12 ({Delta}RMST increment 0.74 months/yr, 0.32-1.19). The HR was 0.55 (0.43-0.71) before month 12 and 1.16 (0.87-1.54) afterwards (post/pre ratio 2.10); investigator assessment showed similar attenuation. Similar ratios occurred in KEYNOTE-564 at its first interim analysis (2.02), whose benefit persisted, and in SORCE and PROTECT (2.09, 2.59), whose benefit faded. From months 12 to 30 (post hoc), the DFS difference changed by -3.7 percentage points (-8.1 to 0.8) with central review and 0.6 (-4.0 to 5.0) with investigator assessment. Data were reconstructed, and follow-up was short. Conclusions and Clinical Implications: Relative hazard reductions with belzutifan were greater before month 12; durability of the absolute DFS advantage is uncertain and assessment-dependent, so single-HR projections should be avoided.

Background: Cervical cancer remains a leading cause of cancer death among women in sub-Saharan Africa, with Ghana experiencing persistently high mortality linked to late diagnosis and constrained treatment access. Beyond its clinical burden, cervical cancer treatment is a socially demanding experience requiring women to mobilise financial, practical, informational, and emotional support over time. This study explored the social networks surrounding women during cervical cancer treatment and the social support exchanged within them at a tertiary referral facility in Ghana. Methods: A qualitative descriptive design, informed by an interpretivist epistemological orientation, was employed. Eight women receiving treatment at the National Centre for Radiotherapy, Oncology and Nuclear Medicine, Korle-Bu Teaching Hospital, Accra, were recruited using criterion-based purposive sampling and interviewed individually using a semi-structured guide until data saturation was reached. Interviews were audio-recorded, transcribed verbatim, and analysed using reflexive thematic analysis, supported by Atlas.ti version 7.5.7. Results: Five themes were generated. Disclosure functioned as a gatekeeping process through which women selectively determined who entered their support network, shaped by anticipated stigma. Despite valuing the support they received, women displayed marked reluctance to request it directly, relying on indirect strategies and expressing gratitude regardless of whether support met their actual needs. Support networks consistently narrowed around a single family member, most often a daughter or sibling, who provided the bulk of financial, practical, and informational assistance, while more peripheral relationships receded. Social support functioned not merely as emotional comfort but as a precondition for accessing and continuing treatment at all, particularly given widely inadequate insurance coverage. Finally, some women experienced discomfort reconciling their need for support with a prior identity as habitual providers of care to others. Conclusion: Social networks and support during cervical cancer treatment in Ghana are actively constructed through disclosure, constrained by reluctance to seek help, and concentrated around a single caregiver, functioning as a determinant of whether treatment can be accessed and sustained rather than merely a source of comfort. Formalizing support around, rather than in place of, these informal networks could strengthen both access to and continuity of cervical cancer care in similarly resourced settings.

Introduction: Acute gastroenteritis (AGE) is a cause of childhood morbidity and may be associated with human adenovirus (HAdV) infection. This study aimed to investigate the occurrence of HAdV in fecal samples from children with AGE in Salvador, Bahia, Brazil, as well as to molecularly characterize the identified strains and evaluate their cytopathic effects in cell culture. Methods: A total of 131 samples were analyzed using the nested polymerase chain reaction (Nested-PCR) technique. Molecular characterization was performed through Sanger sequencing and phylogenetic analysis, while Vero cell cultures were used to investigate the occurrence of cytopathic effects. Results: Of the samples analyzed, 13 (9.9%) tested positive for HAdV, while 118 (90.1%) were negative. The highest detection frequency was observed in children aged three years or younger, particularly those under one year of age. Phylogenetic analysis identified variants related to HAdV-F41 and HAdV-B3, revealing genetic differences and distinct clustering patterns compared with reference sequences. In cell culture, cytopathic effects were observed four days after inoculation, although further analyses are required to confirm productive viral replication. Conclusion: These findings demonstrate the presence of HAdV in the samples studied and contribute to understanding its genetic diversity and circulation in Salvador, highlighting the importance of epidemiological surveillance and further studies on its role in the etiology of childhood AGE.

Background: Cancer patients face a significantly elevated risk of severe COVID-19 outcomes. Although vaccination is a cornerstone of prevention, data on vaccination coverage and association with survival among Russian cancer patients remain scarce. We assessed COVID-19 vaccination coverage and its association with overall survival in a population-based cohort of cancer patients in Northwest Russia. Methods: This retrospective registry-based cohort study integrated data from the Population-Based Cancer Registry (PBCR) of the Arkhangelsk Region and the Nenets Autonomous Okrug, regional vaccination records, and an artificial intelligence (AI)-based analysis of chest computed tomography (CT) scans. The cohort consisted of 1,144 cancer patients who underwent CT between August 2020 and April 2021. Vaccination status was ascertained via data linkage. Overall survival (OS) was compared between vaccinated and unvaccinated patients using Kaplan-Meier analysis and multivariable Cox proportional hazards regression, adjusted for demographic, clinical, and AI-derived CT biomarkers. To mitigate immortal time bias, the primary analysis used a landmark approach restricted to patients alive on March1, 2021 (N=1,136). A sensitivity analysis used a November1, 2021 landmark (N=894). Vaccination status was defined as receipt of at least one dose before the landmark date. Results: Only 6.6% (n=76) of patients received at least one dose of a COVID-19 vaccine (Sputnik V or Sputnik Light). Vaccinated patients were more likely to have earlier-stage cancer and were less likely to be receiving active treatment. In the primary landmark analysis, vaccination was associated with a significantly higher 3-year OS (80.3% vs. 45.7%, p<0.001). In multivariable analysis, vaccination was independently associated with a 60% lower hazard of all-cause mortality (adjusted HR 0.40, 95% CI 0.25-0.64). AI-detected COVID-19 pneumonia on baseline CT was also an independent predictor of poorer survival (adjusted HR 1.32, 95% CI 1.09-1.59). In the sensitivity analysis (November1, 2021 landmark), the adjusted HR for vaccination was 0.56 (95% CI 0.34-0.92), showing a consistent but attenuated association. Conclusion: This study reveals critically low COVID-19 vaccination coverage among cancer patients in Northwest Russia. Nevertheless, vaccination was strongly associated with a substantial survival benefit, underscoring its importance as a potentially lifesaving intervention for this vulnerable population.

Cash incentives are widely used in clinical research to support recruitment and retention, yet their ethical implications, particularly in high-risk settings such as HIV cure-related studies, remain inadequately understood. This study examined how key stakeholders perceive participant payment relative to other study characteristics when deciding whether to participate in HIV cure research. Using a choice-based conjoint (CBC) experiment, we assessed preferences among people living with HIV (PLWH), HIV researchers, and Institutional Review Board (IRB) members/bioethicists. Participants (N=88) completed eight choice tasks involving hypothetical HIV cure study scenarios varying across six attributes: incentive amount, invasiveness, requirement to pause HIV medications, time commitment, first-in-human status, and cost reimbursement. Across all participants, payment amount emerged as the most influential attribute (29.3%), followed by procedure invasiveness (22.3%) and the requirement to pause HIV medication (17.6%). The highest hypothetical payment level ($200 per visit) was significantly preferred. However, subgroup analyses revealed important differences: PLWH prioritized payment most strongly, whereas researchers and IRB members/bioethicists placed greater emphasis on minimizing invasiveness. The requirement to pause HIV medication was a salient concern across groups, though relatively more influential for IRB members/bioethicists than for PLWH. Time commitment and ancillary cost reimbursement had comparatively lower impact on decision-making. These findings highlight the central role of financial incentives in shaping willingness to participate in HIV cure research, raising ethical considerations regarding potential undue influence, especially in higher-risk studies. At the same time, stakeholders value minimizing procedural risks and disruptions to treatment. This study underscores the need for clearer guidance on appropriate payment practices and for balancing incentives with ethical safeguards, particularly in trials involving antiretroviral therapy interruption.

To characterise temporal changes in antimicrobial resistance (AMR) among clinically important bacterial pathogens in Iraq during 2021-2024 and examine their implications for empirical antimicrobial therapy and stewardship. We conducted a retrospective longitudinal analysis of aggregated national AMR surveillance data for Escherichia coli, Klebsiella pneumoniae, Pseudomonas aeruginosa and Staphylococcus aureus. Annual resistance proportions were evaluated across clinically relevant antimicrobials. Temporal change was characterised using absolute percentage-point changes and exploratory linear regression. Resistance trajectories were interpreted in relation to empirical treatment options and antimicrobial stewardship. The analysis included 92,338 organism records: 40,496 (43.9%) E. coli, 24,621 (26.7%) S. aureus, 18,223 (19.7%) K. pneumoniae and 8,998 (9.7%) P. aeruginosa. In 2024, ceftriaxone resistance reached 82.9% in E. coli and 65.2% in K. pneumoniae, while ciprofloxacin resistance was 55.4% and 57.9%, respectively. Meropenem resistance reached 37.4% in K. pneumoniae and 62.3% in P. aeruginosa. Conversely, resistance declined for amoxicillin-clavulanate in E. coli (83.5% in 2021 to 57.2% in 2024) and piperacillin-tazobactam in P. aeruginosa (46.4% to 32.9%). Several pathogen-antimicrobial combinations showed marked year-to-year variation, and no temporal trend remained statistically significant after false discovery rate correction. Resistance to several agents central to empirical therapy remains high in Iraq, while substantial carbapenem resistance constrains reliance on carbapenem escalation when resistance to other {beta}-lactams is suspected. Heterogeneous trajectories indicate that empirical recommendations should not rely on single-year national antibiograms alone and support regular integration of national and local resistance surveillance into empirical treatment and antimicrobial stewardship strategies.

In resource-limited settings plasma is usually transported to centralized laboratories for HIV RNA quantification; often by motor vehicles using dry ice. Any decay in plasma HIV RNA when near the threshold used to define virologic failure could impact clinical management. However, maintaining a cold chain during transport can be costly and limit the frequency of shipments, which can delay clinical assessments and also negatively impact patient care. Transporting plasma at ambient temperatures could facilitate timely measurements of plasma HIV RNA viral loads (VL). We conducted a stability study of HIV RNA in plasma held for 1, 3, 5, and 7 days at a range of temperatures (4{degrees}C, 30{degrees}C, and 37{degrees}C) to simulate the durations and temperatures specimens could experience during transport. Thirteen large volume plasma specimens with VL ranging from 2.7-5.53 log10 copies/mL were evaluated. Mean changes in VL between Day-0 to Day-1, Day-3, Day-5 or Day-7 were calculated, with decays >0.5 log10 c/mL considered clinically relevant. Compared to Day 0, the VL of plasma stored at 4{degrees}C and 30{degrees}C remained stable across the Days tested. The VL in plasma stored at 37{degrees}C had a progressive decline at Day-1, Day-3, Day-5 and Day-7 (means of -0.04, -0.19, -0.33. -0.34 log10 c/mL, respectively), with a decay of >0.5 log10 observed in 3/13 (23%) specimens at Day-7. A linear regression analysis showed that plasma specimens stored at 37{degrees}C significantly decayed over time (slope -0.054, 95% CI -0.079, -0.029; p=0.01). Any decay observed among specimens stored at 4{degrees}C and 30{degrees}C was not clinically relevant nor statistically significant. Our observations suggest that HIV RNA levels in plasma should remain stable if transported to centralized laboratories at ambient temperatures of [&le;]30{degrees}C or chilled by cold packs over a period [&le;]7 days. Transporting specimens with cold packs instead of dry ice could reduce costs and facilitate the timely monitoring of VL used to assess and guide antiretroviral therapy.

Since its inception in 2003, the United States President's Emergency Plan for AIDS Relief (PEPFAR) has played a central role in HIV/AIDS prevention and treatment across Sub-Saharan Africa. Following the January 2025 suspension of United States foreign aid, which includes PEPFAR funding, countries across Sub-Saharan Africa demonstrated varying governmental responses to the resulting HIV funding disruptions. This study evaluates whether national characteristics were associated with a country's ability to respond to this funding crisis. Countries in Sub-Saharan Africa receiving PEPFAR funding were classified into one of three response categories: Level 1 (minimal or no governmental response), Level 2 (government response without sufficient plans or resources to fully offset funding losses), or Level 3 (high governmental response with strategies to maintain HIV/AIDS prevention and treatment services). Response categories were compared with national Human Development Index (HDI), GDP per capita, HIV prevalence, total population living with HIV, annual HIV mortality, and historical PEPFAR funding. Univariable proportional-odds ordinal logistic regression was used to identify factors associated with response level. Five countries (17.2%) were classified as Level 1, 10 (34.5%) as Level 2, and 14 (48.3%) as Level 3. Higher HDI was significantly associated with stronger governmental response (OR = 4.05; 95% CI, 1.49-11.04; Holm-adjusted p = 0.0376). GDP per capita (OR = 2.35; 95% CI, 1.00-5.51; unadjusted p = 0.0489) and HIV prevalence (OR = 3.53; 95% CI, 1.03-12.11; unadjusted p = 0.0452) demonstrated positive associations before adjustment for multiple comparisons, but neither remained significant after Holm correction (adjusted p = 0.2261 for both). Historical PEPFAR funding, total population living with HIV, and annual HIV mortality were not significantly associated with response level after adjustment. Countries with higher levels of human development demonstrated stronger governmental responses to the 2025 PEPFAR funding disruptions. Several countries with minimal documented responses were also affected by active conflict or political instability, potentially compounding their vulnerability to treatment interruptions. These findings suggest that broader national development may play an important role in governmental responses to funding disruptions and highlight the need to strengthen resilient health systems, diversify HIV financing, and prioritize support for countries at greatest risk of future funding shocks.

Background Influenza vaccines have seen many changes over recent years in terms of both policy recommendations and product types. Immune responses and vaccine effectiveness vary by vaccine strain composition and product type. This study aimed to explore this variation on a regional level through examining spatial and temporal autocorrelations of vaccine uptake of different product types within Michigan from 2017 to 2021. Methods Influenza vaccine administration data from the 2017/18 to 2021/22 seasons were obtained from the Michigan Care Improvement Registry. Population size estimates for 2017 and 2019 were obtained from the Michigan Department of Health and Human Services. Age-standardized and age-stratified vaccination rates were computed. Disparate county-level vaccine uptake clusters were constructed using spatial autocorrelation indicators and spatiotemporal clusters were identified using scan statistics. Linear mixed effect models were used to study the impact of social vulnerability and urbanicity level on seasonal influenza vaccination rate. Results Vaccination incidence rates for adjuvanted, recombinant, and nasal sprays vaccines and for any vaccines increased significantly through the study period. County-level spatiotemporal clusters of type-specific uptake rates were identified. Most notably, we identified an emerging cluster with high uptake of adjuvanted vaccine radiating from Ottawa County, located in suburban Grand Rapids, and the disappearance of high uptake cluster for high-dose vaccine uptake in the area. Vaccination rates by any product type were found to vary seasonally and showed weak negative association with more rural regions. The overall vaccination rates appear to be lower among counties with higher social vulnerability in certain urbanicity levels, but social vulnerability and urbanicity were not significantly associated with overall vaccination rate during the study period. Conclusions Vaccine type-specific uptake was spatially and temporally diverse in Michigan between 2017 and 2022. Mid and Northern Michigan had consistently relatively lower vaccination rate compared to other regions in Michigan.

Background: Hepatitis E virus (HEV) is highly endemic in several African countries with high mortality rate among pregnant women. The prevalence of HEV in Niger among pregnant women is unknown. We hereby aim to report the prevalence and risk factors of HEV among pregnant women in Niamey, Niger. Methods: Blood samples were collected from pregnant women attending antenatal consultation in three selected Health centers in Niamey. Data were collected for socio demographic characteristics using a structured questionnaire. Samples were tested using ELISA and qRT-PCR for anti- HEV IgM and RNA detection respectively. HEV associated risk factors were determined using multivariate logistic regression models. Results: A total of 491 pregnant women were enrolled with mean age of 26.5 years. The prevalence of anti-HEV IgM antibodies was 17.1%, while HEV RNA was detected in 3.46% of participants, indicating recent and active HEV infection. Anti-HEV IgM seropositivity was more frequent among women aged 26-30 years and those in the third trimester of pregnancy. Gravidity was significantly associated with HEV RNA positivity (p = 0.032). In multivariable analysis, the use of well water was independently associated with HEV infection (aOR = 75.70; 95% CI: 1.23-4643.20; p = 0.039). Conclusion: In view of the high seroprevalence of HEV among pregnant women, preventive measures including hygiene sensitization should be prioritized. Further studies should be conducted to assess the real impact of HEV infection on maternal and fetal health.

Introduction: Japan achieves high retention and viral suppression among people on antiretroviral therapy, yet treatment starts late. Most people obtain subsidised treatment through a physical disability certificate for HIV-related immune dysfunction, which requires two blood tests at least four weeks apart. We quantified the diagnosis-to-treatment cascade, identified who waits and tested whether the second test changes certification. Methods: Retrospective cohort of people newly diagnosed with HIV at 11 designated AIDS core hospitals in 2015 to 2024. We measured intervals from screening to hospital visit and to antiretroviral therapy, and emulated certification from the first test alone and from the two-test rule under every possible number of non-laboratory criteria (k = 0 to 8). Results: Of 1302 people (96% men; 68% with CD4 <350 cells/L or AIDS), 1036 (80%) followed the two-test pathway and 261 started treatment after one test, mostly because of AIDS or acute infection. People reached the hospital a median of 11 days after screening. Treatment then began a median of 70 days after the first visit in the two-test pathway and 11 days in the single-test pathway; 0.2% and 60.9% started within 14 days. Delay rose with CD4 count: 46 days when the mean count was [&le;]200 cells/L, 117 days when it was >500 with a laboratory criterion (16% of the two-test pathway) and 334 days when it was >500 without one (3%; adjusted hazard ratio 0.14, 95% confidence interval 0.09 to 0.23). Medians ranged from 35 to 96 days across facilities. The second test changed little: the first CD4 count agreed with the mean of two (intraclass correlation coefficient 0.959), HIV-RNA [&ge;]5000 copies/mL persisted in 97.6%, and certification status agreed in 99.0% for k [&ge;]1 (92.5% for k = 0), with discordance concentrated near 500 cells/L; the first test gave a milder grade in at most 2.9%. Conclusions: The statutory second test adds at least four weeks before antiretroviral therapy in Japan without changing who is certified, and delays most the people with the highest CD4 counts. Certification on a single test, with treatment separated from the subsidy procedure, would remove a delay that has no clinical or administrative justification.
