Spanish Translation and Cultural Adaptation of the Intensive Care Unit Delirium Playbook.

Background: A lack of high-quality provider education hinders the delivery of standard-of-care delirium detection and prevention practices in the intensive care unit (ICU). To fill this gap, we developed and validated an e-learning ICU Delirium Playbook consisting of eight videos and a 44-question knowledge assessment quiz. Given the increasing Spanish-speaking population worldwide, we translated and cross-culturally adapted the playbook from English into Spanish. Objective: To translate and culturally adapt the ICU Delirium Playbook into Spanish, the second most common native language worldwide. Methods: The translation and cross-cultural adaptation process included double forward and back translations and harmonization by a 14-person interdisciplinary team of ICU nurses and physicians, delirium experts, methodologists, medical interpreters, and bilingual professionals representing many Spanish-speaking global regions. After a preeducation quiz, a nurse focus group completed the playbook videos and posteducation quiz, followed by a semistructured interview. Results: The ICU Delirium Playbook: Spanish Version maintained conceptual equivalence to the English version. Focus group participants posted mean (standard deviation) pre- and post-playbook scores of 63% (10%) and 78% (12%), with a 15% (11%) pre-post improvement (P = 0.01). Participants reported improved perceived competency in performing the Confusion Assessment Method for the ICU and provided positive feedback regarding the playbook. Conclusion: After translation and cultural adaptation, the ICU Delirium Playbook: Spanish Version yielded significant knowledge assessment improvements and positive feedback. The Spanish playbook is now available for public dissemination.

Continuous ovarian stimulation: a proof-of-concept study exploring the uninterrupted use of corifollitropin α in DuoStim cycles for enhanced efficiency and patient convenience (Alicante protocol).

Objective: To explore the use of weekly continuous dosing of corifollitropin α in DuoStim cycles. Design: Pilot-matched case-control study. Setting: Private fertility center. Patients: Cases were defined as DuoStim cycles performed from November 2022 to May 2023 receiving weekly continuous dosing of corifollitropin α (n = 15). Controls were chosen from a database comprising DuoStim cycles conducted at our institution during the years 2021/2022. Matching was done on a 1-to-1 basis, based on antimüllerian hormone values (±0.4 pmol/L) and age (n = 15). Interventions: Injections of corifollitropin α once every 8 days, along with uninterrupted oral administration of micronized progesterone 200 mg/d (for luteinizing hormone surge prevention) throughout the follicular and luteal phases for ovarian stimulation. Oocyte retrieval. Main outcome measures: Total number of cumulus-oocyte complexes and metaphase II oocytes obtained in follicular + luteal phase stimulation. Secondary outcomes evaluated fertilization rates, number of blastocysts, days of stimulation, number of injectables required, and gonadotropin cost. Results: The study group achieved similar total oocyte and MII yield vs. daily follicle-stimulating hormone protocol (13.3 ± 6.9 vs. 11.8 ± 6.1 and 10.4 ± 6.3 vs. 9.2 ± 4.6, respectively). All secondary outcomes showed no significant differences. The study group experienced a significant reduction of injections to complete a DuoStim cycle (4.5 ± 1.4 vs. 35.2 ± 12.2; mean deviation -30.7; 95% confidence interval, -37.5- to -23.9)]. Conclusions: Corifollitropin α on a weekly basis throughout a DuoStim cycle yields an equivalent number of oocytes as standard daily follicle-stimulating hormone administration while drastically reducing the number of required injections. Trial registration number: NCT05815719. EudraCT: 2022-003177-32.

TREATMENT OF SEVERE HYPERTRIGLYCERIDEMIA THROUGH THERAPEUTIC PLASMA EXCHANGE IN PATIENTS WITH ACUTE PANCREATITIS OR AT RISK OF DEVELOPING IT. / TRATAMIENTO DE LA HIPERTRIGLICERIDEMIA GRAVE MEDIANTE RECAMBIO PLASMÁTICO TERAPÉUTICO EN PACIENTES CON PANCREATITIS AGUDA O EN RIESGO DE PADECERLA.

INTRODUCTION AND OBJECTIVES: TPE drastically reduces serum triglyceride (sTG), but its role in the treatment of hypertriglyceridemia-induced acute pancreatitis (HTG-AP) or at risk of developing it, is not well established. The objectives were to assess the effectiveness and safety of TPE in the treatment of severe HTG (sHTG), as well as to evaluate the severity of HTG-AP treated with TPE. MATERIALS AND METHODS: Observational-retrospective-single-center study, in which a descriptive analysis of sHTG treated with TPE was conducted, with the aim of treating HTG-AP or preventing its recurrence. TPE was performed if sTG≥ 1000 mg/dL after 24 hours of admission. RESULTS: 42 TPE were performed to treat 35 sHTG in 23 patients: 29 HTG-AP, and 6 sHTG with previous HTG-AP. Among the patients, 37% (13/55) were women, with 37±14 years-old, 74.3% had normal BMI (25/35), 34% (12/35) were drinking >40 g/alcohol/day and 54% (19/35) were diabetics. TPE significantly reduced the baseline sTG (4425±2782 mg/dL vs. 709±353 mg/dL, p<0.001) in a single session, achieving a mean percentage reduction of 79±13%; 20% (7/35) of sHTG cases required two TPE sessions to reduce sTG to <1000 mg/dL. Adverse effects were reported in 4/42 TPE sessions (9,5%). sHTG-AP was observed in 3% of cases (1/29), and there were no deaths. sTG at 24 hours of admission showed no relation with the severity of APs. CONCLUSION: The treatment of sHTG with TPE, with the aim of treating HTG-AP or preventing its recurrence, reduces sTG quickly and safety.

Assessment of performance and comparison of three commercial HDV RNA detection assays: implications for diagnosis and treatment monitoring.

Objectives: Precise HDV-RNA detection and quantification are pivotal for diagnosis and monitoring of response to newly approved treatment. We evaluate the performance of three HDV RNA detection and quantification assays. Methods: Hepatitis Delta RT-PCR system kit, EurobioPlex HDV assay, and RoboGene HDV RNA Quantification kit 2.0 were used for testing 151 HBsAg-positive samples, 90 HDV-RNA negative and 61 HDV-RNA positive. We also evaluated serial dilutions of the WHO international standard for HDV, PEI 7657/12. All HDV-RNA positive samples were genotyped using a next-generation sequencing strategy. Results: Qualitative results indicated a 100% concordance between tests. Quantitative results correlated well, r2 = 0.703 (Vircell-vs-Eurobio), r2 = 0.833 (Vircell-vs-RoboGene), r2 = 0.835 (Robogene-vs-Eurobio). Bias index was 2.083 (Vircell-vs-Eurobio), -1.283 (Vircell-vs-RoboGene), and -3.36 (Robogene-vs-Eurobio). Using the WHO IS, Vircell overestimated the viral load by 0.98 log IU/mL, Eurobio by 1.46 log IU/mL, and RoboGene underestimated it by 0.98 log IU/mL. Fifty-nine samples were successfully genotyped (Genotype 1, n=52; Genotype 5, n=7; Genotype 6, n=1), with similar results for correlation and bias. Conclusion: This study underscores the necessity of using reliable HDV-RNA detection and quantification assays, as evidenced by the high concordance rates in qualitative detection and the observed variability in quantitative results. These findings highlight the importance of consistent assay use in clinical practice to ensure accurate diagnosis and effective treatment monitoring of HDV infection.

Do Consumers Value Agri-Food Industries' Environmental Commitment? The Case of the Table Olive Industry.

An increasing number of food companies are voluntarily adopting environmental policies and sustainability initiatives to tackle climate change. The aims of this study were to analyse the presence of environmental labels on table olive products, to explore consumer perceptions of these companies' environmental commitment and initiatives, and to evaluate the influence of these messages on purchasing decisions. For this purpose, a market study was conducted in different hypermarkets and supermarkets in Spain, and an online survey was submitted to consumers (n = 227). The results show that environmental claims and/or certifications related to sustainability do not appear on table olive products, despite most of the companies that produce and/or market table olives having adopted environmental and sustainability policies and commitments (34.3% have their environmental policy published on their website). More than 85% of consumers positively value these companies' sustainability commitments and consider environmental initiatives to be very important. As a sector of consumers pays close attention to environmental commitments, it would be interesting for table olive companies to identify their sustainability policies on their products' labelling to, thus, facilitate pro-environmental consumer purchase choices. These results could help the food industry develop the best strategies to publicise their social and environmental policies and commitments.

Tackling obstructive sleep apnea with pharmacotherapeutics: expert guidance.

INTRODUCTION: The efficacy of non-pharmacotherapeutic treatment of obstructive sleep apnea, a highly prevalent condition with serious cardiometabolic and neurocognitive health consequences, is well established. Supplementing traditional treatment strategies with medications can improve symptoms and reduce side effects. Efforts to identify medications that target the causes of sleep apnea have met with mixed success. However, this remains a worthwhile objective for researchers to pursue, given the potential benefit pharmacotherapy could bring to those patients who reject or struggle to adhere to existing treatments. AREAS COVERED: This article presents the case for obstructive sleep apnea pharmacotherapy including drugs that reduce the occurrence of apnea events, such as weight loss agents, ventilation activators and muscle and nervous system stimulants, drugs that alleviate symptoms, such as wake-promoting agents for excessive daytime sleepiness, and drugs that improve adherence to existing treatments, such as hypnotics. Literature was accessed from PubMed between 1 March 2024 and 18 April 2024. EXPERT OPINION: Exciting recent advances in both our understanding of obstructive sleep apnea pathology and in the techniques used to identify therapeutic agents and their targets combine to embolden a positive outlook for the expanded use of drugs in tackling this consequential disease.

Thrombosis and infections associated with PICC in onco-hematological patients, what is their relevance?

PURPOSE: Peripherally inserted central venous catheters (PICC) in the onco-hematological patients may be associated with thrombosis or infections that may have short- to medium-term repercussions. MATERIAL AND METHODS: Single-centre retrospective analysis of a prospectively collected cohort. Primary objective was to establish the PICC-thrombosis and infections incidence. Secondary objectives were to analyze profile of patients suffering from these complications and variables associated with an increased likelihood of developing these events. RESULTS: 549 patients were recruited. 58.5% (n = 321) were oncology patients and 41.5% (n = 228) hematology patients. The incidence of PICC-associated thrombosis was 3.5% (n = 19). Thrombosis was associated with progression of the underlying malignant pathology in 10.6% (n = 2) of cases. No association was found between clinical variables analysed and development of thrombosis. Incidence of PICC-associated infections was 7.65% (n = 42). In the 30 days prior to PICC infection, 57.1% (n = 24) had a febrile syndrome of another focus, 73.8% (n = 11) had been hospitalized, 49.5% (n = 25) had a neutrophil count of 0-500 cells/mm3 and 47.6% (n = 20) had an episode of neutropenic fever. Variables significantly associated with the development of infection were hematological patients, high-flow PICC, 3-lm PICC or PICC insertion because of administration of vesicant therapy. CONCLUSIONS: Incidence of PICC-associated thrombosis is low and apparently less prognostically aggressive than other forms of thrombosis associated with cancer, without identify predictive factors. Infection was more prevalent and the identification of risk factors in our series could facilitate its prevention.

Uncover your inner power: Breaking leadership biases in global healthcare.

Women currently represent approximately 70% of the global healthcare workforce, 60.9% of the global dental workforce, 77.6% of the US healthcare workforce, and 36.7% of the US dental workforce. The American Dental Association states that the number of practicing women dentists in the United States has increased by 2.25 times since 2001, with a projected trajectory to level off by 2040. Despite having a major impact on the healthcare sector globally, women earn 24% less than men and only serve in 25% of senior leadership positions. In the US dental schools, only 14% of faculty serve in administrative roles, and as of April 2022, 28.6% of the US dental school deans were women, indicating gender underrepresentation in the highest roles of academic leadership. This corresponds to the data on gender parity still not being the norm in many societies and workplaces and can be attributed to public policies, stereotypical perceptions, and individual factors. Five key factors have been identified to be crucial for women's entry or advancement in global health leadership: a) public policy, b) community, c) institutional, d) interpersonal, and e) individual. Individual self-improvement and institutional practices may be used to overcome these barriers to women's leadership in healthcare and shift the power dynamics toward reinforcing gender equality. These transformative changes are measured through women's collective capacities and skills, relationship dynamics, community perceptions, and environmental practices. This article recognizes the present obstacles to women in healthcare leadership and proposes strategies to achieve gender equality both through individual and institutional practices.

Multi-center evaluation of the Research Use Only NeuMoDx monkeypox virus (MPXV) fully automated real-time PCR assay.

The mpox outbreak, caused by monkeypox virus (MPXV), accelerated the development of molecular diagnostics. In this study, we detail the evaluation of the Research Use Only (RUO) NeuMoDx MPXV assay by multiple European and US sites. The assay was designed and developed by Qiagen for the NeuMoDx Molecular Systems. Primers and probes were tested for specificity and inclusivity in silico. The analytical sensitivity of the assay was determined by testing dilutions of synthetic and genomic MPXV DNA. A total of 296 clinical samples were tested by three sites; the Johns Hopkins University (US), UZ Gent (Belgium, Europe), and Hospital Universitario San Cecilio (Spain, Europe). The analytical sensitivity of the assay was 50 copies/mL for both clades I and II. The assay showed 100% in silico identity for 80 clade I and 99.98% in silico identity for 5,162 clade II genomes. Clade II primers and probes showed 100% in silico specificity; however, identity of at least one of the two sets of clade I primers and probes with variola, cowpox, camelpox, and vaccinia viruses was noticed. The clinical validation showed sensitivity of 99.21% [95% confidence interval (CI): 95.66-99.98%] and specificity of 96.64% (95% CI: 91.62-99.08%) for lesion swab samples. The NeuMoDx MPXV Test shows acceptable analytical and clinical performance. The assay improves the laboratory's workflow as it consolidates nucleic acid extraction, PCR, data analysis, and interpretation and can be interfaced. The Test Strip can differentiate clades I and II, which has important laboratory safety implications. IMPORTANCE: In this manuscript, we provide detailed in silico analysis and clinical evaluation of the assay using a large cohort of clinical samples across three academic centers in Europe and the United States. Because the assay differentiates MPXV clades I and II, this manuscript is timely due to the current need to rule out the regulated clade I by diagnostic clinical laboratories. In December 2023, and due to first report of cases of sexually transmitted clade I infections in the Democratic Republic of the Congo, when generic assays that do not differentiate the clades are used, samples are considered regulated. The assay meets the need of full automation and has a marked positive impact on the laboratory workflow.

Green infant formula analysis: Optimizing headspace solid-phase microextraction of carbonyl compounds associated with lipid peroxidation using GC-MS and pentafluorophenylhydrazine derivatization.

The refinement and optimization of a method combining headspace solid-phase microextraction (HS-SPME) with gas chromatography-mass spectrometry (GC-MS) was successfully performed for the first time to determine seven carbonyl and dicarbonyl compounds, including glyoxal, methylglyoxal, dimethylglyoxal, and malondialdehyde in infant formulae, related to lipid peroxidation. HS-SPME was utilized for simultaneous extraction and derivatization with pentafluorophenylhydrazine (PFPH). Critical parameters such as temperature, pH, extractive phase, and salting-out were meticulously investigated and fine-tuned by an asymmetrical 2232//9 screening design to ensure the method's efficacy and reliability. Optimal conditions included a PFPH concentration of 5 g/L, pH 5.0, head-space extraction at 60 °C within 10 min, utilizing a DVB/CAR/PDMS coating, and a 20% w/w salting-out. The analytical validation of this method, compliant with FDA guidelines, demonstrated exceptional linearity, sensitivity, specificity, precision (RSD ≤13.8%), and accuracy (84.8% ≤ recovery ≤111.5%). The metric approach AGREEprep confirms its eco-friendliness, marking a significant step towards an environmentally conscious approach in infant formula analysis. An occurrence study conducted on 25 infant formula samples revealed widespread carbonyl and dicarbonyl compounds in both powdered and liquid variants. ANOVA results exhibited variations in compound concentrations among different sample groups. Clustering analyses delineated distinct groups based on carbonyl content, indicating the potential of these compounds as markers for lipid peroxidation and food quality assessment. This method serves as a valuable tool for evaluating infant formula quality, stability towards oxidation, and safety.

Molecular and phylogenetic characterization of the monkeypox outbreak in the South of Spain.

Background and Aim: Until the May 2022 Monkeypox (MPXV) outbreak, which spread rapidly to many non-endemic countries, the virus was considered a viral zoonosis limited to some African countries. The Andalusian circuit of genomic surveillance was rapidly applied to characterize the MPXV outbreak in the South of Spain. Methods: Whole genome sequencing was used to obtain the genomic profiles of samples collected across the south of Spain, representative of all the provinces of Andalusia. Phylogenetic analysis was used to study the relationship of the isolates and the available sequences of the 2022 outbreak. Results: Whole genome sequencing of a total of 160 MPXV viruses from the different provinces that reported cases were obtained. Interestingly, we report the sequences of MPXV viruses obtained from two patients who died. While one of the isolates bore no noteworthy mutations that explain a potential heightened virulence, in another patient the second consecutive genome sequence, performed after the administration of tecovirimat, uncovered a mutation within the A0A7H0DN30 gene, known to be a prime target for tecovirimat in its Vaccinia counterpart. In general, a low number of mutations were observed in the sequences reported, which were very similar to the reference of the 2022 outbreak (OX044336), as expected from a DNA virus. The samples likely correspond to several introductions of the circulating MPXV viruses from the last outbreak. The virus sequenced from one of the two patients that died presented a mutation in a gene that bears potential connections to drug resistance. This mutation was absent in the initial sequencing before treatment.

T-FINDER: A highly sensitive, pan-HLA platform for functional T cell receptor and ligand discovery.

Effective, unbiased, high-throughput methods to functionally identify both class II and class I HLA-presented T cell epitopes and their cognate T cell receptors (TCRs) are essential for and prerequisite to diagnostic and therapeutic applications, yet remain underdeveloped. Here, we present T-FINDER [T cell Functional Identification and (Neo)-antigen Discovery of Epitopes and Receptors], a system to rapidly deconvolute CD4 and CD8 TCRs and targets physiologically processed and presented by an individual's unmanipulated, complete human leukocyte antigen (HLA) haplotype. Combining a highly sensitive TCR signaling reporter with an antigen processing system to overcome previously undescribed limitations to target expression, T-FINDER both robustly identifies unknown peptide:HLA ligands from antigen libraries and rapidly screens and functionally validates the specificity of large TCR libraries against known or predicted targets. To demonstrate its capabilities, we apply the platform to multiple TCR-based applications, including diffuse midline glioma, celiac disease, and rheumatoid arthritis, providing unique biological insights and showcasing T-FINDER's potency and versatility.

Prevalence and Phenotypic Susceptibility to Doravirine of the HIV-1 Reverse Transcriptase V106I Polymorphism in B and Non-B Subtypes.

BACKGROUND: Limited data are available regarding the susceptibility of the reverse transcriptase V106 polymorphism to doravirine. METHODS: Doravirine susceptibility was measured in site-directed mutants (SDMs) containing V106I, V106A, V106M, and Y188L mutations in subtype B (NL4-3, HXB2) and CRF02_AG background and in recombinant viruses with RT harboring V106I alone derived from 50 people with HIV. RESULTS: HIV-1 B subtype was detected in 1523 of 2705 cases. Prevalence of V106I was 3.2% in B and 2.5% in non-B subtypes, and was higher in subtype F (8.1%) and D (14.3%). Fold-changes (FC) in susceptibility for SDMs were below doravirine biological cutoff (3.0) for V106I, but not for V106A, V106M, and Y188L. Clinically derived viruses tested included 22 B (median FC, 1.2; interquartile range [IQR], 0.9-1.6) and 28 non-B subtypes (median FC, 1.8; IQR, 0.9-3.0). Nine (18%) viruses showed FC values equal or higher than the doravirine biological FC cutoff. CONCLUSIONS: The prevalence of the HIV-1 RT V106I polymorphism in MeditRes HIV consortium remains low, but significantly more prevalent in subtypes D and F. V106I minimally decreased the susceptibility to doravirine in SDMs and most clinical isolates. Reduced susceptibility seems to occur at increased frequency in subtype F1; however, the clinical impact remains to be investigated. CLINICAL TRIALS REGISTRATION: NCT04894357.

Targeted long-read sequencing identifies and characterizes structural variants in cases of inherited platelet disorders.

BACKGROUND: Genetic diagnosis of inherited platelet disorders (IPDs) is mainly performed by high-throughput sequencing (HTS). These short-read-based sequencing methods sometimes fail to characterize the genetics of the disease. OBJECTIVES: To evaluate nanopore long-read DNA sequencing for characterization of structural variants (SVs) in patients with IPDs. METHODS: Four patients with a clinical and laboratory diagnosis of Glanzmann thrombasthenia (GT) (P1 and P2) and Hermansky-Pudlak syndrome (HPS) (P3 and P4) in whom HTS missed the underlying molecular cause were included. DNA was analyzed by both standard HTS and nanopore sequencing on a MinION device (Oxford Nanopore Technologies) after enrichment of DNA spanning regions covering GT and HPS genes. RESULTS: In patients with GT, HTS identified only 1 heterozygous ITGB3 splice variant c.2301+1G>C in P2. In patients with HPS, a homozygous deletion in HPS5 was suspected in P3, and 2 heterozygous HPS3 variants, c.2464C>T (p.Arg822∗) and a deletion affecting 2 exons, were reported in P4. Nanopore sequencing revealed a complex SV affecting exons 2 to 6 in ITGB3 (deletion-inversion-duplication) in homozygosity in P1 and compound heterozygosity with the splice variant in P2. In the 2 patients with HPS, nanopore defined the length of the SVs, which were characterized at nucleotide resolution. This allowed the identification of repetitive Alu elements at the breakpoints and the design of specific polymerase chain reactions for family screening. CONCLUSION: The nanopore technology overcomes the limitations of standard short-read sequencing techniques in SV characterization. Using nanopore, we characterized novel defects in ITGB3, HPS5, and HPS3, highlighting the utility of long-read sequencing as an additional diagnostic tool in IPDs.

Transmitted drug resistance to antiretroviral drugs in Spain during the period 2019-2021.

To evaluate the prevalence of transmitted drug resistance (TDR) to nucleoside and nonnucleoside reverse transcriptase inhibitors (NRTI, NNRTI), protease inhibitors (PI), and integrase strand transfer inhibitors (INSTI) in Spain during the period 2019-2021, as well as to evaluate transmitted clinically relevant resistance (TCRR) to antiretroviral drugs. Reverse transcriptase (RT), protease (Pro), and Integrase (IN) sequences from 1824 PLWH (people living with HIV) were studied. To evaluate TDR we investigated the prevalence of surveillance drug resistance mutations (SDRM). To evaluate TCRR (any resistance level ≥ 3), and for HIV subtyping we used the Stanford v.9.4.1 HIVDB Algorithm and an in-depth phylogenetic analysis. The prevalence of NRTI SDRMs was 3.8% (95% CI, 2.8%-4.6%), 6.1% (95% CI, 5.0%-7.3%) for NNRTI, 0.9% (95% CI, 0.5%-1.4%) for PI, and 0.2% (95% CI, 0.0%-0.9%) for INSTI. The prevalence of TCRR to NRTI was 2.1% (95% CI, 1.5%-2.9%), 11.8% for NNRTI, (95% CI, 10.3%-13.5%), 0.2% (95% CI, 0.1%-0.6%) for PI, and 2.5% (95% CI, 1.5%-4.1%) for INSTI. Most of the patients were infected by subtype B (79.8%), while the majority of non-Bs were CRF02_AG (n = 109, 6%). The prevalence of INSTI and PI resistance in Spain during the period 2019-2021 is low, while NRTI resistance is moderate, and NNRTI resistance is the highest. Our results support the use of integrase inhibitors as first-line treatment in Spain. Our findings highlight the importance of ongoing surveillance of TDR to antiretroviral drugs in PLWH particularly with regard to first-line antiretroviral therapy.

Evaluation of a combined detection of SARS-CoV-2 and its variants using real-time allele-specific PCR strategy: an advantage for clinical practice.

This study aimed to assess the ability of a real-time reverse transcription polymerase chain reaction (RT-PCR) with multiple targets to detect SARS-CoV-2 and its variants in a single test. Nasopharyngeal specimens were collected from patients in Granada, Spain, between January 2021 and December 2022. Five allele-specific RT-PCR kits were used sequentially, with each kit designed to detect a predominant variant at the time. When the Alpha variant was dominant, the kit included the HV69/70 deletion, E and N genes. When Delta replaced Alpha, the kit incorporated the L452R mutation in addition to E and N genes. When Omicron became dominant, L452R was replaced with the N679K mutation. Before incorporating each variant kit, a comparative analysis was carried out with SARS-CoV-2 whole genome sequencing (WGS). The results demonstrated that RT-PCR with multiple targets can provide rapid and effective detection of SARS-CoV-2 and its variants in a single test. A very high degree of agreement (96.2%) was obtained between the comparison of RT-PCR and WGS. Allele-specific RT-PCR assays make it easier to implement epidemiological surveillance systems for effective public health decision making.

Importance of the origin, organic production and other extrinsic parameters in fruit and vegetable choices.

The aims of the present work were to evaluate consumers' perceptions and purchasing habits in relation to fruit and vegetables and to determine the importance of the production type, price and geographical origin of such products for consumers' purchasing decisions. For this purpose, an online consumer survey was conducted to determine Spanish people's opinions and consumption habits in relation to fruit and vegetables, especially those from organic farming. The survey also included a part to assess the importance that consumers attach to different extrinsic attributes in oranges and avocado pears (with a conjoint analysis), and a section to determine the participants' ethnocentrism. Consumers agree that organic food respects the environment more, contains fewer 'chemicals' and is more natural. Price is the first reason why many people do not buy organic food, followed by them thinking that they do not offer any added value and they are difficult to find. For the Spanish population, country of origin, local production, seasonality and price are much more important attributes for purchasing fruit and vegetables than them being organic. This study reflects a relatively high ethnocentrism level of the surveyed population, especially in older individuals. Given consumer preference for km 0/local and seasonal products, and the importance of these parameters for the environment, promoting the market of such products would help to achieve some Sustainable Development Goals. This study offers a vision of the trends of Spanish consumers in relation to fruit and vegetable preferences, which can help producers and distributors to design new strategies that focus on meeting consumer demands.

Molecular characterization of patients with chronic hepatitis C virus infection in Jordan: implications on response to direct-acting antiviral therapy.

OBJECTIVES: To investigate the molecular characteristics of Hepatitis C Virus (HCV) detected in patients with chronic HCV infection in Jordan. METHODS: The study included 48 Jordanian treatment-naïve patients with active chronic HCV recruited from seven governorates. HCV genotype and the resistance-associated substitutions (RAS) profile were investigated by next-generation sequencing of the NS5B, NS5A, and NS3 regions of HCV. RESULTS: "Unusual genotype 4 subtypes" were detected in four (8.3%) patients (4n-n = 1, 4o-n = 2, 4v-n = 1); one patient (2.1%) was co-infected by genotypes 1b+4a. Overall prevalence of NS5A RASs was 38.3% (3% cutoff); genotype 4a showed the highest NS5A RAS prevalence (n = 11, 55.0%). Overall prevalence of NS3 RASs was 21.8% (7/32), all genotype 1a-infected patients. CONCLUSIONS: We report, for the first time in Jordanian patients with chronic HCV infection, the detection of unusual genotype 4 subtypes 4n, 4o, and 4v. Baseline RASs in NS5A are frequent, with complex RASs patterns in some of the unusual subtypes. Our data support the need for sequencing surveillance programs in sub-Saharan Africa, Asia, and the Middle East and North African region to monitor response to treatment in these subtypes and to facilitate the World Health Organization's 2030 elimination strategy.

Influence of the starting day of luteal phase stimulation on double stimulation cycles.

Background: Double ovarian stimulation is one of the most used strategies in poor-prognosis patients. There is a high heterogeneity between the studies regarding the execution of this stimulation protocol. The aim of this study was to investigate whether the day on which luteal phase stimulation begins after the first oocyte retrieval affects ovarian response in DuoStim cycles. Methods: This observational and retrospective study included 541 DuoStim cycles between January 2018 and December 2021 in a private fertility clinic. Patients were assigned to 4 groups according to the timing of the onset of luteal phase stimulation after oocyte retrieval (0-2nd day, 3rd day, 4th day and 5th-6th day). The primary outcome was the number of oocytes retrieved in the luteal phase in each group. Results: No differences were found between groups in the number of oocytes collected (5.12 ± 3.56 vs. 5.39 ± 3.74 vs. 5.61 ± 3.94 vs. 5.89 ± 3.92; p=0,6), MII or number of follicles. An increase in the duration of stimulation was found when stimulation started on the 4th day (10.42 ± 2.31 vs. 10.68 ± 2.37 vs. 11.27 ± 2.40 vs. 10.65 ± 2.37 days, p=0,033). A lower number of fertilized oocytes was observed when stimulation began before the fourth day (3.36 ± 2.80 vs. 3.95 ± 2.53 vs. 4.03 ± 2.73 vs. 4.48 ± 3.11; p=0,036). The number of blastocysts was higher when the stimulation started 5-6 days after retrieval (1.82 ± 1.74 vs. 2.13 ± 1.61 vs. 2.33 ± 2.06 vs. 2.91 ± 2.39; p= 0,030). Discussion: The number of oocytes retrieved does not differ depending on the day that stimulation begins. However, oocytes competence in terms of fertilized oocytes and blastulation, appears to be lower when the second stimulation starts before the fourth day after oocyte retrieval.
