The impact of the COVID-19 pandemic and the free vaccination policy on seasonal influenza vaccination uptake among older adults in Ningbo, Eastern China.

In 2020-21, during the COVID-19 pandemic, a free influenza vaccination program was initiated among the elderly residents in Ningbo, China. The impact of the COVID-19 pandemic and free vaccination policy on influenza vaccine uptake needs to be evaluated. The influenza vaccine uptake among individuals born before 31 December, 1962 from 2017-18 to 2022-23 season in Ningbo was analyzed. Multivariate logistic regressions were used to estimate the impact of the COVID-19 pandemic and free vaccination policy. Our analysis included an average of 1,856,565 individuals each year. Influenza vaccination coverage increased from 1.14% in 2017-18 to 33.41% in 2022-23. The vaccination coverage among the free policy target population was 50.03% in 2022-23. Multivariate analysis showed that free vaccination policy increased influenza vaccine uptake most (OR = 11.99, 95%CI: 11.87-12.11). The initial phase of the pandemic was associated with a positive effect on influenza vaccination (OR = 2.09, 95%CI: 2.07-2.12), but followed by a negative effect in the subsequent two seasons(2021-22: OR = 0.75, 95%CI: 0.73-0.76; 2022-23: OR = 0.40, 95%CI: 0.39-0.40). COVID-19 vaccination in the current season was a positive predictor of influenza vaccine uptake while not completing booster COVID-19 vaccination before was negative predictor in 2022-23. Having influenza vaccine history and having ILI medical history during the last season were also positive predictors of influenza vaccine uptake. Free vaccination policies have enhanced influenza vaccination coverage among elderly population. The COVID-19 pandemic plays different roles in different seasons. Our study highlights the need for how to implement free vaccination policies targeting vulnerable groups with low vaccination coverage.

Tagging large CNV blocks in wheat boosts digitalization of germplasm resources by ultra-low-coverage sequencing.

BACKGROUND: The massive structural variations and frequent introgression highly contribute to the genetic diversity of wheat, while the huge and complex genome of polyploid wheat hinders efficient genotyping of abundant varieties towards accurate identification, management, and exploitation of germplasm resources. RESULTS: We develop a novel workflow that identifies 1240 high-quality large copy number variation blocks (CNVb) in wheat at the pan-genome level, demonstrating that CNVb can serve as an ideal DNA fingerprinting marker for discriminating massive varieties, with the accuracy validated by PCR assay. We then construct a digitalized genotyping CNVb map across 1599 global wheat accessions. Key CNVb markers are linked with trait-associated introgressions, such as the 1RS·1BL translocation and 2NvS translocation, and the beneficial alleles, such as the end-use quality allele Glu-D1d (Dx5 + Dy10) and the semi-dwarf r-e-z allele. Furthermore, we demonstrate that these tagged CNVb markers promote a stable and cost-effective strategy for evaluating wheat germplasm resources with ultra-low-coverage sequencing data, competing with SNP array for applications such as evaluating new varieties, efficient management of collections in gene banks, and describing wheat germplasm resources in a digitalized manner. We also develop a user-friendly interactive platform, WheatCNVb ( http://wheat.cau.edu.cn/WheatCNVb/ ), for exploring the CNVb profiles over ever-increasing wheat accessions, and also propose a QR-code-like representation of individual digital CNVb fingerprint. This platform also allows uploading new CNVb profiles for comparison with stored varieties. CONCLUSIONS: The CNVb-based approach provides a low-cost and high-throughput genotyping strategy for enabling digitalized wheat germplasm management and modern breeding with precise and practical decision-making.

Design and implementation of multi-band reflectarray metasurface for 5G millimeter wave coverage enhancement.

A compact low-profile multi-band millimeter-wave (mm-wave) reflectarray metasurface design is presented for coverage enhancement in 5G and beyond cellular communication. The proposed single-layer metasurface exhibits a stable reflection response under oblique incidence angles of up to 60 ∘ at 24 and 38 GHz, and transmission response at 30 GHz, effectively covering the desired 5G mm-wave frequency bands. The proposed reflectarray metasurface is polarization insensitive and performs equally well under TE and TM polarized incident waves due to the symmetric pattern. In addition, the low profile of the proposed metasurface makes it appropriate for conformal applications. In comparison to the state-of-the-art, the proposed reflectarray metasurface unit cell design is not only compact (3.3  ×  3.3 mm 2 ) but also offers two reflections and one transmission band based on a single-layer structure. It is easy to reconfigure the proposed metasurface unit cell for any other frequency band by adjusting a few design parameters. To validate the concept of coverage enhancement, a 32  ×  x32 unit-cell prototype of the proposed reflectarray metasurface is fabricated and measured under different scenarios. The experimental results demonstrate that a promising signal enhancement of 20-25 dB is obtained over the entire 5G mm-wave n258, n259, and n260 frequency bands. The proposed reflectarray metasurface has a high potential for application in mm-wave 5G networks to improve coverage in dead zones or to overcome obstacles that prevent direct communication linkages.

Litigation in access to universal health coverage for children and adolescents in Brazil.

Background: Brazil's Unified Health System (SUS) ensures universal, equitable, and excellent quality health coverage for all. The broad right to health, supported by the Constitution, has led to excessive litigation in the public sector. This has negatively impacted the financial stability of SUS, created inequality in children and adolescents' access to healthcare, and affected communication between the healthcare system and the judiciary. The enactment of Law Number 13.655 on 25 April 2018, proposed significant changes in judicial decisions. This study aimed to investigate decision-making changes in health litigation involving children and adolescents following the implementation of the new normative model. Methods: The study is cross-sectional, analyzing 3753 national judgment documents from all State Courts of Brazil, available on their respective websites from 2014 to 2020. It compares regional legal decisions before and after the promulgation of Law Number 13.655/2018. Data tabulation, statistical analysis, textual analysis, coding, and counting of significant units in the collected documents were performed. The results of data cross-referencing are presented in tables and diagrams. Results: The majority (96.86%) of legal claims (3635 cases) received partial or total provision of what was prescribed by the physician. The Judiciary predominantly handled these cases individually. The analysis indicates that the decisions made did not adhere to the norms established in 2018. Conclusion: Regional heterogeneity in health litigation was observed, and there was no significant variability in decisions during the studied period, even after the implementation of the new normative paradigm in 2018. Technical-scientific support was undervalued by the magistrates. Prioritizing litigants undermines equity in access to Universal Health Coverage for children and adolescents.

Poor coverage of quality-adjusted antenatal care services: a population-level assessment by visit and source of antenatal care services in Bihar state of India.

Background: Despite the evidence on the poor quality of antenatal care (ANC) services, significant gap remains in the understanding of quality-adjusted coverage at the population-level for each ANC visit and by the source of ANC services, and in equity in this coverage. Methods: All births between July 2020 and June 2021 were listed from 261,124 households (91.5% participation) representative of the Bihar state. Mothers of all stillbirths and neonatal deaths, and of 25% random sample of livebirths who survived the neonatal period provided data on each ANC visit up to a maximum of first 4 ANC visits, including the source of ANC services and the services received (weight measurement, blood pressure checked, abdomen checked, urine sample taken, and blood sample taken). An ANC visit was deemed of quality if all of these services were received in that visit. We report the coverage of quality-adjusted ANC services (Q-ANC) for ANC visits 1-4 disaggregated by source of ANC services and wealth index (WI). Weighted proportions are reported to take into account the sampling design. Findings: A total of 30,412 births were reported by 29,517 women, and 7270 (82.1%) of the 8853 eligible women participated. Overall, 19,950 unique ANC visits from 6929 women were available for analysis, of which 41.7%, 13.8% and 44.5% were at Village Health and Nutrition Day (VNHD), public facility, and with a private provider, respectively. A total of 4409 (65.3%) of the 1st ANC visits were undertaken at VHND, with the proportion of private provider ANC visits increasing significantly from ANC visit 1 to ANC visit 4 (p < 0.001). Q-ANC coverage considering all ANC visits was 20.9% (95% CI 20.7-21.2); and was 0.9% (95% CI 0.8-1.0), 29.9% (95% CI 29.2-30.7) and 36.9% (95% CI 36.5-37.4) for ANC visits in VHND, public facilities, and with private provider, respectively. Q-ANC coverage in the public facility was significantly lower in the 4th ANC visit (25.1%; 95% CI 23.4-26.9) as compared with visits 1 to 3, whereas it was the highest for 1st ANC visit with private provider (50.2%; 95% CI 49.2-51.1) and then dropped for visits 2 to 4. Irrespective of the source of ANC services, Q-ANC coverage increased significantly with increasing WI quartile for ANC visits 1 and 2, with WI quartile 3 women having significantly less coverage for ANC visit 3 compared to the rest, and no significant difference seen in the coverage of ANC 4 visit. Varied pattern of Q-ANC coverage by WI for each ANC visit was seen for public facility and private provider visits. Interpretation: With only 2 of 10 ANC visits deemed of adequate quality, sustainable delivery of quality ANC services are needed for every pregnant woman through-out the pregnancy irrespective of gestation period, number of ANC visit, and source of ANC services. Funding: The funding was provided by the India office of the Bill & Melinda Gates Foundation, USA.

Disability, comorbidities and risk determinants at end of TB treatment in Kenya, Uganda, Zambia and Zimbabwe.

BACKGROUND: We examined the feasibility of assessing and referring adults successfully completing TB treatment for comorbidities, risk determinants and disability in health facilities in Kenya, Uganda, Zambia and Zimbabwe. METHODS: This was a cross-sectional study within national TB programmes. RESULTS: Health workers assessed 1,063 patients (78% of eligible) in a median of 22 min [IQR 16-35] and found it useful and feasible to accomplish in addition to other responsibilities. For comorbidities, 476 (44%) had HIV co-infection, 172 (16%) had high blood pressure (newly detected in 124), 43 (4%) had mental health disorders (newly detected in 33) and 36 (3%) had diabetes mellitus. The most common risk determinants were 'probable alcohol dependence' (15%) and malnutrition (14%). Disability, defined as walking <400 m in 6 min, was found in 151/882 (17%). Overall, 763 (72%) patients had at least one comorbidity, risk determinant and/or disability. At least two-thirds of eligible patients were referred for care, although 80% of those with disability needed referral outside their original health facility. CONCLUSIONS: Seven in 10 patients completing TB treatment had at least one comorbidity, risk determinant and/or disability. This emphasises the need for offering early patient-centred care, including pulmonary rehabilitation, to improve quality of life, reduce TB recurrence and increase long-term survival.

CONTEXTE: Nous avons examiné la faisabilité d'évaluer et de référer les adultes ayant terminé avec succès le traitement de la TB pour les comorbidités, les déterminants de risque et l'invalidité dans les établissements de santé au Kenya, en Ouganda, en Zambie et au Zimbabwe. MÉTHODES: Il s'agissait d'une étude transversale menée dans le cadre des programmes nationaux de lutte contre la TB. RÉSULTATS: Les agents de santé ont évalué 1 063 patients (78% des personnes éligibles) en médiane de 22 min (IQR 16­35) et ont jugé utile et réalisable d'accomplir cette tâche en plus de leurs autres responsabilités. Pour les comorbidités, 476 (44%) étaient co-infectés par le VIH, 172 (16%) souffraient d'hypertension artérielle (dont 124 nouvellement diagnostiqués), 43 (4%) présentaient des troubles de santé mentale (dont 33 nouvellement diagnostiqués) et 36 (3%) étaient diabétiques. Les déterminants de risque les plus courants étaient une « dépendance probable à l'alcool ¼ (15%) et la malnutrition (14%). L'invalidité, définie comme une marche <400 m en 6 min, a été observée chez 151/882 (17%) des patients. Dans l'ensemble, 763 (72%) des patients présentaient au moins une comorbidité, un déterminant de risque et/ou une invalidité. Au moins deux tiers des patients éligibles ont été référés pour des soins, bien que 80% de ceux souffrant d'invalidité aient besoin d'être référés en dehors de leur établissement de santé d'origine. CONCLUSIONS: Sept patients sur 10 ayant terminé le traitement de la TB présentaient au moins une comorbidité, un déterminant de risque et/ou une invalidité. Cela souligne la nécessité d'offrir des soins précoces centrés sur le patient, y compris une réadaptation pulmonaire, pour améliorer la qualité de vie, réduire la récurrence de la TB et augmenter la survie à long terme.

HIV PrEP Coverage Among Black Adults: A Concept Analysis of the Inequities, Disparities, and Implications.

Background: Significant racial disparities exist in HIV pre-exposure prophylaxis (PrEP) coverage in the United States (U.S), with Black individuals experiencing seven times higher new HIV infection rates compared to their White counterparts. Despite being the highest priority population at risk for HIV, Black adults have the lowest PrEP coverage, impacting the overall progress toward meeting the ending the HIV epidemic (EHE) goals in the U.S. Methods: Utilizing the Walker and Avant method, this concept analysis examined existing literature and U.S. Centers for Disease Control and Prevention resources to explore HIV PrEP coverage. Results: Findings highlighted a lack of clarity in the concept, resulting in four operational definitions. To address this ambiguity, a conceptual definition of HIV PrEP coverage was proposed, focusing on equitable access to PrEP medication among sexually active individuals aged 18-64 years, particularly those traditionally underserved and would benefit from PrEP. This inclusive definition aims to align with the dynamics of sexual behavior in racial minority groups. Key attributes of this conceptual definition include estimates of PrEP use, access, need, cost, side effects, frequency of HIV testing, and self-efficacy. Antecedents entail HIV status, testing behaviors, transmission risks, and communication with health care providers. Consequences involve perceptions of risk, screening routines, provider biases, stigma, and potential HIV transmission reduction. Conclusion: Analyzing HIV PrEP coverage offers useful insights into social and structural factors exacerbating health inequities in the field of HIV prevention and control. This concept analysis underscores the importance of unified sexual health communication, diverse approaches to PrEP access for racial minorities, and improved sexual health policies for Black adults. Moreover, understanding and advocating for equity in HIV PrEP coverage is crucial for addressing the existing racial disparities and achieving the EHE objectives in the U.S.

SMS-based interventions for improving child and adolescent vaccine coverage and timeliness: a systematic review.

BACKGROUND: The aim of this review was to investigate the impact of short message service (SMS)-based interventions on childhood and adolescent vaccine coverage and timeliness. METHODS: A pre-defined search strategy was used to identify all relevant publications up until July 2022 from electronic databases. Reports of randomised trials written in English and involving children and adolescents less than 18 years old were included. The review was conducted in accordance with PRISMA guidelines. RESULTS: Thirty randomised trials were identified. Most trials were conducted in high-income countries. There was marked heterogeneity between studies. SMS-based interventions were associated with small to moderate improvements in vaccine coverage and timeliness compared to no SMS reminder. Reminders with embedded education or which were combined with monetary incentives performed better than simple reminders in some settings. CONCLUSION: Some SMS-based interventions appear effective for improving child vaccine coverage and timeliness in some settings. Future studies should focus on identifying which features of SMS-based strategies, including the message content and timing, are determinants of effectiveness.

Hydrogel-based photobioreactor for Solid-State cultivation of Chlorella vulgaris.

Solid-state cultivation is a promising technology for algal biomass production, achieving high productivities without the need for dewatering. However, such systems have suffered from high evaporation, and capital costs. Here is described a hydrogel photobioreactor (hPBR) with the aim of reducing water demand in solid-state cultivations. Two designs are described with "Design A" offering better humidity control overgrowth conditions. A biomass productivity of 2.41gm-2d-1, and 2.87gm-2d-1 when using physically crosslinked poly(vinyl alcohol) (pPVA) and chemically crosslinked PVA (cPVA) respectively were achieved with Chlorella vulgaris with a water demand around 0.44 kg g-1 of biomass. Over the 23 days of growth, the lipid content increased from 18.9 % to 56.6 % and 13.8 % to 43.2 % for pPVA and cPVA respectively, and the chlorophyll content decreased by more than 81 %. However, cell viability stayed high at over 98 % and surface coverage analysis showed good coverage of the gel surface.

Clinical Outcomes of Celiac Artery Coverage vs Preservation During Thoracic Endovascular Aortic Repair.

BACKGROUND: Adequate proximal and distal seal zones are necessary for successful Thoracic Endovascular Aortic Repair (TEVAR). Often, the achievement of an adequate distal seal zone requires celiac artery (CA) coverage by endograft with or without preservation of CA blood flow. The outcomes of CA coverage without its flow preservation were studied only in small case series. This study aims to determine the difference in outcomes between CA coverage with vs without preservation of CA blood flow during TEVAR using a multi-institutional national database. METHODS: Vascular Quality Initiative (VQI) was reviewed for all TEVAR patients distally landing in Zone 6. The cohort was divided into TEVAR with vs without CA flow preservation. Demographic, clinical, and perioperative characteristics, as well as post-operative mortality, morbidities, and complications, were compared between the groups. Univariate and multivariate regression analyses were performed. RESULTS: Out of 25,549 reviewed patients, 772 had a distal landing in zone 6, 212 of which (27.5%) had TEVAR without CA flow preservation, whereas 560 (72.5%) underwent TEVAR with CA flow preservation. Indications for TEVAR were: aneurysm in 431 (55.8%), dissection in 247 (32.0%), or other in 94 (12.2%) cases. Patients who underwent TEVAR without CA flow preservation had statistically significantly higher rates of 30-day mortality (11.3% vs 5.9%, p=0.010), 30-day disease/treatment-related mortality (8.0% vs 4.3%, p=0.039), as well as a tendency of increased intestinal ischemia requiring intervention (1.9% vs 0.5%, p=0.077). After adjusting for potential confounders, CA coverage without flow preservation was associated with more than a two-fold increase in the overall 30-day mortality (OR: 2.83, 95%CI: 1.35-5.92, p=0.006) and 30-day disease/treatment-related mortality (OR: 2.72, 95%CI: 1.11-6.72, p=0.029). In a sub-group analysis based on disease pathology, these results persisted only in the aneurysm group (30-day mortality (OR: 2.36, 95%CI: 1.01-5.48, p=0.047), 30-day disease/treatment-related mortality (OR: 2.88, 95%CI: 1.08-7.67, p=0.034)), whereas there was no significant association between CA flow preservation status and the endpoints in the dissection subgroup (30-day mortality (OR: 1.16, 95%CI: 0.22-6.05, p=0.856), 30-day disease/treatment-related mortality (OR: 0.90, 95%CI: 0.16-5.19, p=0.911)). CONCLUSIONS: CA coverage during TEVAR without preservation of its blood flow is associated with significantly higher mortality in patients with aortic aneurysm, but not dissection. In patients with aortic aneurysm CA flow should be preserved during TEVAR whenever feasible, whereas in patients with dissection, it may be safe to cover CA without preservation of its flow. Prospective studies should be done to confirm these findings and compare the open vs endovascular revascularization techniques on outcomes.

Compressive strain in Cu catalysts: Enhancing generation of C2+ products in electrochemical CO2 reduction.

Elastic strain in Cu catalysts enhances their selectivity for the electrochemical CO2 reduction reaction (eCO2RR), particularly toward the formation of multicarbon (C2+) products. However, the reasons for this selectivity and the effect of catalyst precursors have not yet been clarified. Hence, we employed a redox strategy to induce strain on the surface of Cu nanocrystals. Oxidative transformation was employed to convert Cu nanocrystals to CuxO nanocrystals; these were subsequently electrochemically reduced to form Cu catalysts, while maintaining their compressive strain. Using a flow cell configuration, a current density of 1 A/cm2 and Faradaic efficiency exceeding 80% were realized for the C2+ products. The selectivity ratio of C2+/C1 was also remarkable at 9.9, surpassing that observed for the Cu catalyst under tensile strain by approximately 7.6 times. In-situ Raman and infrared spectroscopy revealed a decrease in the coverage of K+ ion-hydrated water (K·H2O) on the compressively strained Cu catalysts, consistent with molecular dynamics simulations and density functional theory calculations. Finite element method simulations confirmed that reducing the coverage of coordinated K·H2O water increased the probability of intermediate reactants interacting with the surface, thereby promoting efficient C-C coupling and enhancing the yield of C2+ products. These findings provide valuable insights into targeted design strategies for Cu catalysts used in the eCO2RR.

Applying the Effective Programme Coverage framework to assess gaps in HIV prevention programmes for female sex workers and men who have sex with men in Nairobi, Kenya: findings from an expanded Polling Booth Survey.

INTRODUCTION: Measuring the coverage of HIV prevention services for key populations (KPs) has consistently been a challenge for national HIV programmes. The current frameworks and measurement methods lack emphasis on effective coverage, occur infrequently, lack timeliness and limit the participation of KPs. The Effective Programme Coverage framework, which utilizes a programme science approach, provides an opportunity to assess gaps in various coverage domains and explore the underlying reasons for these gaps, in order to develop targeted solutions. We have demonstrated the application of this framework in partnership with the KP community in Nairobi, Kenya, using an expanded Polling Booth Survey (ePBS) method. METHODS: Data were collected between April and May 2023 among female sex workers (FSWs) and men who have sex with men (MSM) using (a) PBS, (b) bio-behavioural survey and (c) focus group discussions. Data collection and analysis involved both KP community and non-community researchers. Descriptive analysis was performed, and proportions were used to assess the programme coverage gaps. The data were weighted to account for the sampling design and unequal selection probabilities. Thematic analysis was conducted on the qualitative data. RESULTS: The condom programme for FSW and MSM had low availability (60.2% and 50.9%), contact (68.8% and 65.9%) and utilization (52.1% and 43.9%) coverages. The pre-exposure prophylaxis (PrEP) programme had very low utilization coverage for FSW and MSM (4.4% and 2.8%), while antiretroviral therapy utilization coverage was higher (86.6% and 87.7%). Reasons for coverage gaps included a low peer educator-to-peer ratio, longer distance to the clinics, shortage of free condoms supplied by the government, experienced and anticipated side effects related to PrEP, and stigma and discrimination experienced in the facilities. CONCLUSIONS: The Effective Programme Coverage framework allows programmes to assess coverage gaps and develop solutions and a research agenda targeted at specific domains of coverage with large gaps. The ePBS method works well in collecting data to understand coverage gaps rapidly and allows for the engagement of the KP community.

The impact of the COVID-19 vaccination programme on symptomatic and severe SARS-CoV-2 infection during a period of Omicron variant dominance in Ireland, December 2021 to March 2023.

BackgroundAs Ireland prepared for an autumn 2023 COVID-19 vaccination booster campaign, there was concern that vaccine fatigue would affect uptake, which has been abating.AimThis study aimed to quantify the direct impact of the COVID-19 vaccination programme in Ireland on averted COVID-19-related outcomes including symptomatic presentations to primary care/community testing centres, emergency department (ED) presentations, hospitalisations, intensive care unit (ICU) admissions and deaths, in individuals aged ≥ 50 years, during Omicron dominance.MethodsWe conducted a retrospective observational COVID-19 vaccine impact study in December 2021-March 2023 in Ireland. We used national data on notified outcomes and vaccine coverage, as well as vaccine effectiveness (VE) estimates, sourced from the World Health Organization's live systematic review of VE, to estimate the count and prevented fraction of outcomes in ≥ 50-year-olds averted by the COVID-19 vaccination programme in this age group.ResultsThe COVID-19 vaccination programme averted 48,551 symptomatic COVID-19 presentations to primary care/community testing centres (36% of cases expected in the absence of vaccination), 9,517 ED presentations (53% of expected), 102,160 hospitalisations (81% of expected), 3,303 ICU admissions (89% of expected) and 15,985 deaths (87% of expected).ConclusionsWhen Omicron predominated, the COVID-19 vaccination programme averted symptomatic and severe COVID-19 cases, including deaths due to COVID-19. In line with other international vaccine impact studies, these findings emphasise the benefits of COVID-19 vaccination for population health and the healthcare system and are relevant for informing COVID-19 booster vaccination programmes, pandemic preparedness and communicating the reason for and importance of COVID-19 vaccination in Ireland and internationally.

[The comparative analysis of health care systems based on rating definition].

The comparative analysis of effectiveness and efficiency of health care systems functioning causes a number of difficulties due to different indicators applied in countries as assessment tools, different data collection mechanisms and differences in nature and dimension of determining indicators. To ensure comparability of absolute values of various indicators and possibility to compare activities of single medical organizations and effectiveness of health care system of both various Subjects of the Russian Federation and health care system as a whole, it is possible to apply different rating techniques. The article presents comprehensive comparative analysis of activities of health care systems based on construction of rating using integral indicators of public health: indicators of key functioning of health systems (financial support and infrastructure development), total mortality from non-communicable diseases, probability of dying at the age of 30 to 70 years from any of cardiovascular diseases, cancer, diabetes or chronic respiratory diseases, universal health coverage index, life expectancy (at birth and at the age of 60). The comprehensive comparative analysis of results permitted to to conclude that the greatest financial costs for health care and best level of infrastructural support (beds and medical personnel) in countries with health insurance system. At that, according to ranking results and all selected integral public health indicators, health insurance system took the first place.

Serotype distribution, antibiotic resistance, multilocus sequence typing, and virulence factors of invasive and non-invasive Streptococcus pneumoniae in Northeast China from 2000 to 2021.

Streptococcus pneumoniae infection is a major public health concern with high morbidity and mortality rates. This study aimed to evaluate the serotype distribution, antimicrobial resistance changes, clonal composition, and virulence factors of S. pneumoniae isolates causing pneumococcal disease in northeast China from 2000 to 2021. A total of 1,454 S. pneumoniae isolates were included, with 568 invasive strains and 886 non-invasive strains. The patients from whom the S. pneumoniae were isolated ranged in age from 26 days to 95 years, with those ≤ 5 years old comprising the largest group (67.19%). 19 F, 19 A, 23 F, 14, and 6B were the most common serotypes, of which 19 A and 19 F were the main serotypes of invasive and non-invasive S. pneumoniae, respectively. CC271 was the most common multilocus sequence type. Serotype 14 had the lowest expression of cbpA, rrgA, and psrP genes, but expression levels of 19 A and 19 F genes were similar. All isolates were sensitive to ertapenem, moxifloxacin, linezolid, and vancomycin but highly resistant to macrolides, tetracyclines, and cotrimoxazole. Simultaneous resistance to erythromycin, clindamycin, tetracyclines, and trimethoprim/sulfamethoxazole was common pattern among multidrug-resistant isolates. Non-invasive S. pneumoniae had higher resistance to ß-lactam antibiotics than invasive strains. 19 A and 19 F were the main strains of penicillin-resistant S. pneumoniae. The resistance rate of ß-lactam antibiotics decreased from 2017 to 2021 compared to previous periods. Including PCV13 in the national immunization program can reduce the morbidity and mortality rates of pneumococcal disease effectively.

Clinical and genetic analysis of a case of O'Donnell-Luria-Rodan syndrome manifesting as growth retardation. / 以生长发育迟缓为表现的1例O'Donnell-Luria-Rodanç»¼åˆå¾ä¸´åºŠä¸Žé—ä¼ å­¦ç‰¹å¾åˆ†æž.

O'Donnell-Luria-Rodan (ODLURO) syndrome is an autosomal dominant genetic disorder caused by mutations in the KMT2E (lysine methyltransferase 2E) gene. The Third Xiangya Hospital of Central South University admitted a 12-year and 9-month-old male patient who presented with growth retardation, intellectual disability, and distinctive facial features. Peripheral blood was collected from the patient, and DNA was extracted for genetic testing. Chromosome karyotyping showed 46XY. Whole-exome sequencing and low-coverage massively parallel copy number variation sequencing (CNV-seq) revealed a 506 kb heterozygous deletion in the 7q22.3 region, which includes 6 genes, including KMT2E. The patient was diagnosed with ODLURO syndrome. Both the patient's parents and younger brother had normal clinical phenotypes and genetic test results, indicating that this deletion was a de novo mutation. The clinical and genetic characteristics of this case can help increase clinicians' awareness of ODLURO syndrome.

AFITbin: a metagenomic contig binning method using aggregate l-mer frequency based on initial and terminal nucleotides.

BACKGROUND: Using next-generation sequencing technologies, scientists can sequence complex microbial communities directly from the environment. Significant insights into the structure, diversity, and ecology of microbial communities have resulted from the study of metagenomics. The assembly of reads into longer contigs, which are then binned into groups of contigs that correspond to different species in the metagenomic sample, is a crucial step in the analysis of metagenomics. It is necessary to organize these contigs into operational taxonomic units (OTUs) for further taxonomic profiling and functional analysis. For binning, which is synonymous with the clustering of OTUs, the tetra-nucleotide frequency (TNF) is typically utilized as a compositional feature for each OTU. RESULTS: In this paper, we present AFIT, a new l-mer statistic vector for each contig, and AFITBin, a novel method for metagenomic binning based on AFIT and a matrix factorization method. To evaluate the performance of the AFIT vector, the t-SNE algorithm is used to compare species clustering based on AFIT and TNF information. In addition, the efficacy of AFITBin is demonstrated on both simulated and real datasets in comparison to state-of-the-art binning methods such as MetaBAT 2, MaxBin 2.0, CONCOT, MetaCon, SolidBin, BusyBee Web, and MetaBinner. To further analyze the performance of the purposed AFIT vector, we compare the barcodes of the AFIT vector and the TNF vector. CONCLUSION: The results demonstrate that AFITBin shows superior performance in taxonomic identification compared to existing methods, leveraging the AFIT vector for improved results in metagenomic binning.

Universal health coverage in Pakistan: exploring the landscape of the health system, health seeking behaviours, and utilization of health services.

The attainment of the noble objective of Universal Health Coverage (UHC)- 'leaving no one behind' necessitates sufficient financial resources, an ample supply of skilled healthcare professionals, and the availability of essential services as part of a basic package This paper presents an analysis of the health system, health seeking behaviours and health service utilization en route to UHC in Pakistan. We have used the UHC 14 tracer indicators of service coverage to see where Pakistan stands, what are the gaps and what needs to be done. Pakistan clearly is lagging behind its neighboring countries. The country's health system ought to work on health seeking behaviours and broader determinants of health. The pursuit of UHC demands a shared responsibility and collective action, with stakeholders from different sectors uniting their efforts and expertise. Together, they can establish robust systems, design comprehensive policies, allocate adequate resources, and implement interventions that transcend disciplinary boundaries.
