Accelerating Progress to Reduce the Cancer Burden through Prevention and Control in the US.

Improvements in cancer prevention and control are poised to be main contributors in reducing the burden of cancer in the US. We quantify top opportunities to accelerate progress using projected life years gained (LYG) and deaths averted as measures. We project that over the next 25 years, realistic gains from tobacco control can contribute 0.4 to 17 million additional LYG per intervention and 8.4 million additional LYG from improving uptake of screening programs over the lifetime of 25 annual cohorts. Additional opportunities include addressing modifiable risk factors (excess weight, alcohol consumption), improving methods to prevent or treat oncogenic infections, and reducing cancer health disparities. Investment is needed in the pipeline of new preventive agents and technologies for early detection to continue progress. There is also a need for additional research to improve the access to and uptake of existing and emerging interventions for cancer prevention and control and to address health disparities. These gains are undeniably within our power to realize for the US population.

The impact of knowledge to optimize attitude and behaviour about infertility: Perspectives from students in Morocco.

The aim of this study is to explore knowledge, attitude and behaviour about infertility among young people, to prevent risk factors which should threaten fertility of young people.455 non-medical and medical students participated to this study, by a simple random sampling method. Knowledge state of non-medical group about infertility management was lower than medical group. Participants of non-medical group (p = 0,041) had low knowledge about definition and causes than participants of medical group. 11,5% of female and 10,9% of male of non-medical group opted for Traditional-healer as first solution if treatment fails , none of medical group suggested this option. The first advice of respondents of non-medical was polygamy, adoption and divorce (P= 0,001). Respondents of medical (p= 0,038) had proposed to try fertility treatments more than once time if treatment fails. Government should increase efforts to improve knowledge about infertility for all scholar programs.

Le but de cette étude est d'explorer les connaissances, les attitudes et les comportements concernant l'infertilité chez les jeunes, afin de prévenir les facteurs de risque qui pourraient menacer la fertilité des jeunes. 455 étudiants non-médecins et en médecine ont participé à cette étude, par une simple méthode d'échantillonnage aléatoire. L'état des connaissances du groupe non médical sur la gestion de l'infertilité était inférieur à celui du groupe médical. Les participants du groupe non médical (p = 0,041) avaient une faible connaissance de la définition et des causes par rapport aux participants du groupe médical. 11,5% des femmes et 10,9% des hommes du groupe non médical ont opté pour le guérisseur traditionnel comme première solution en cas d'échec du traitement, aucun membre du groupe médical n'a suggéré cette option. Le premier conseil des répondants non médicaux était la polygamie, l'adoption et le divorce (P= 0,001). Les répondants médicaux (p= 0,038) avaient proposé d'essayer des traitements de fertilité plus d'une fois en cas d'échec du traitement. Le gouvernement devrait redoubler d'efforts pour améliorer les connaissances sur l'infertilité pour tous les programmes universitaires.

Assessment of the effect of unfractionated heparin administered either by intravenous infusion vs. subcutaneous injection on heparin-binding protein, and plasminogen activator inhibitor-1 in critically ill septic patients: a randomized controlled trial.

OBJECTIVE: The study compared the impact of unfractionated heparin (UFH) administered via two routes (infusion and subcutaneous injection) on heparin-binding protein (HBP) and plasminogen activator inhibitor-1 (PAI-1) levels in critically ill sepsis patients. PATIENTS AND METHODS: Forty critically ill sepsis patients were randomly assigned to receive either a low-dose intravenous infusion of UFH (500 units/hour) or subcutaneous UFH (5,000 units/8 hours) for seven days. HBP and PAI-1 were measured at baseline and on days one, two, and seven. RESULTS: Intravenous administration of UFH showed a significant reduction in percentage change of HBP compared to subcutaneous administration on days one [(-35% vs. -13%, p = 0.03*) (*indicates a significant result *p < 0.05, relative to the subcutaneous group)] and seven (-62% vs. -39%, p = 0.02*). Also, the percentage change of PAI-1 was significantly reduced in the infusion group compared to the subcutaneous group on days one (-28% vs. -3%, p = 0.008*), two (-42% vs. -3%, p = 0.001*), and seven (-62% vs. 27%, p = 0.001*), respectively. Furthermore, a significant improvement in the 14-day survival was observed in the infusion group compared to the subcutaneous group (p = 0.008*). CONCLUSIONS: Intravenous infusion was the route of choice for UFH administration in critically ill septic patients, with a promising effect on HBP, PAI-1, and survival.

Next-generation precision medicine for suicidality prevention.

Suicidality remains a clear and present danger in society in general, and for mental health patients in particular. Lack of widespread use of objective and/or quantitative information has hampered treatment and prevention efforts. Suicidality is a spectrum of severity from vague thoughts that life is not worth living, to ideation, plans, attempts, and completion. Blood biomarkers that track suicidality risk provide a window into the biology of suicidality, as well as could help with assessment and treatment. Previous studies by us were positive. Here we describe new studies we conducted transdiagnostically in psychiatric patients, starting with the whole genome, to expand the identification, prioritization, validation and testing of blood gene expression biomarkers for suicidality, using a multiple independent cohorts design. We found new as well as previously known biomarkers that were predictive of high suicidality states, and of future psychiatric hospitalizations related to them, using cross-sectional and longitudinal approaches. The overall top increased in expression biomarker was SLC6A4, the serotonin transporter. The top decreased biomarker was TINF2, a gene whose mutations result in very short telomeres. The top biological pathways were related to apoptosis. The top upstream regulator was prednisolone. Taken together, our data supports the possibility that biologically, suicidality is an extreme stress-driven form of active aging/death. Consistent with that, the top subtypes of suicidality identified by us just based on clinical measures had high stress and high anxiety. Top therapeutic matches overall were lithium, clozapine and ketamine, with lithium stronger in females and clozapine stronger in males. Drug repurposing bioinformatic analyses identified the potential of renin-angiotensin system modulators and of cyclooxygenase inhibitors. Additionally, we show how patient reports for doctors would look based on blood biomarkers testing, personalized by gender. We also integrated with the blood biomarker testing social determinants and psychological measures (CFI-S, suicidal ideation), showing synergy. Lastly, we compared that to machine learning approaches, to optimize predictive ability and identify key features. We propose that our findings and comprehensive approach can have transformative clinical utility.

Reproductive tract complication risks following Chlamydia trachomatis infections: a long-term prospective cohort study from 2008 to 2022.

Background: The clinical and public health relevance of widespread testing for asymptomatic Chlamydia trachomatis (chlamydia) infections is under debate. To address uncertainties in screening programs, we estimate reproductive tract complication risks following asymptomatic and symptomatic chlamydia infections in a long-term prospective cohort. Methods: A cohort of 5704 reproductive-age women recruited from a chlamydia screening study was followed for up to 14 years. Chlamydia positivity was determined using screening polymerase chain reaction test results, self-reported diagnoses (with/without symptoms), and chlamydia Immunoglobulin G antibodies. Outcome data (pregnancies, pelvic inflammatory disease (PID), ectopic pregnancy, and tubal factor infertility) were collected through self-completed questionnaires. Cox regression calculated adjusted hazard ratios (aHR) with confidence intervals (CI) to compare outcomes between time-updated chlamydia groups since sexual debut. Findings: During 104,612 person-years, 2103 (36.9%) women were chlamydia-positive and 3692 women (64.7%) had been pregnant at least once. Risks for PID, ectopic pregnancy and tubal factor infertility were 1.62 (95% CI 1.20-2.17), 1.84 (95% CI 1.14-2.95) and 2.75 (95% CI 1.53-4.94), compared to chlamydia-negatives. aHRs for PID after symptomatic and asymptomatic infections were 2.29 (95% CI 1.62-3.25) and 1.06 (95% CI 0.66-1.69), respectively. Incidence of PID, ectopic pregnancy and tubal factor infertility after symptomatic chlamydia infection remained low with rates per 1000 person-years of 5.8, 1.9, and 1.8, respectively. Interpretation: We found a significantly higher risk of PID, ectopic pregnancy and tubal factor infertility in chlamydia-positive women compared to chlamydia-negative women, although the overall incidence rates of complications remained low. Symptomatic, but not asymptomatic, chlamydia infections were associated with PID risk, suggesting the largest disease burden of complications is in this group.

Flagellar point mutation causes social aggregation in laboratory-adapted Bacillus subtilis under conditions that promote swimming.

Motility allows microbes to explore and maximize success in their environment; however, many laboratory bacterial strains have a reduced or altered capacity for motility. Swimming motility in Bacillus subtilis depends on peritrichous flagella and is carried out individually as cells move by biased random walks toward attractants. Previously, we adapted Bacillus subtilis strain 3610 to the laboratory for 300 generations in lysogeny broth (LB) batch culture and isolated lab-adapted strains. Strain SH2 is motility-defective and in broth culture forms large, frequently spherical aggregates of cells. A single point mutation in the flagellin gene hag that causes amino acid 259 to switch from A to T is necessary and sufficient to cause these social cell aggregates, and aggregation occurs between flagellated cells bearing this point mutation regardless of the strain background. Cells associate when bearing this mutation, but flagellar rotation is needed to pull associating cells into spherical aggregates. Using electron microscopy, we are able to show that the SH2 flagellar filament has limited polymorphism when compared to other flagellar structures. This limited polymorphism hinders the flagellum's ability to function as a motility apparatus but appears to alter its function to that of cell aggregation/adhesion. We speculate that the genotype-specific aggregation of cells producing HagA259T flagella could have increased representation in a batch-culture experiment by allowing similar cells to go through a transfer together and also that this mutation could serve as an early step to evolve sociality in the natural world.IMPORTANCEThe first life forms on this planet were prokaryotic, and the earliest environments were aquatic, and from these relatively simple starting conditions, complex communities of microbes and ultimately multicellular organisms were able to evolve. Usually, motile cells in aqueous environments swim as individuals but become social by giving up motility and secreting extracellular substances to become a biofilm. Here, we identify a single point mutation in the flagellum that is sufficient to allow cells containing this mutation to specifically form large, suspended groups of cells. The specific change in the flagellar filament protein subunits causes a unique change in the flagellar structure. This could represent a distinct way for closely related cells to associate as an early precursor to sociality.

Rapid differentiation of MOGAD and MS after a single optic neuritis.

BACKGROUND: Optic neuritis (ON) is a common manifestation of multiple sclerosis (MS) and myelin-oligodendrocyte-glycoprotein IgG-associated disease (MOGAD). This study evaluated the applicability of optical coherence tomography (OCT) for differentiating between both diseases in two independent cohorts. METHODS: One hundred sixty two patients from seven sites underwent standard OCT and high-contrast visual acuity (HCVA) testing at least 6 months after first ON. Of these, 100 patients (32 MOGAD, 68 MS) comprised the primary investigational cohort, while 62 patients (31 MOGAD, 31 MS) formed a validation cohort. A composite score distinguishing between MOGAD and MS was developed using multivariate logistic regression. RESULTS: Bilateral simultaneous ON occurred more frequently in MOGAD compared to MS (46.9 vs. 11.8%, p < 0.001). OCT revealed more peripapillary retinal nerve fiber layer (pRNFL) atrophy in all segments in MOGAD compared to predominantly temporal pRNFL atrophy in MS (p < 0.001). HCVA was better preserved in MS (p = 0.007). pRNFL thickness in all except for temporal segments was suitable for differentiating MOGAD and MS. Simultaneous bilateral ON and critical atrophy in nasal (< 58.5 µm) and temporal superior (< 105.5 µm) segments were included into the composite score as three independent predictors for MOGAD. The composite score distinguished MOGAD from MS with 75% sensitivity and 90% specificity in the investigational cohort, and 68% sensitivity and 87% specificity in the validation cohort. CONCLUSION: Following a single ON-episode, MOGAD exhibits more pronounced global pRNFL atrophy and lower visual acuity after ON compared to MS. The introduced OCT-based composite score enabled differentiation between the two entities across both cohorts.

Eczema in early childhood increases the risk of allergic multimorbidity.

BACKGROUND: Eczema in early childhood is associated with the development of subsequent allergic diseases, including food allergy (FA), asthma and hay fever. However, eczema has a heterogenous presentation regarding onset age and persistence, which may lead to different allergic outcomes during childhood/adolescence. Recently, sub-phenotypes of eczema have been suggested as predictors of allergic multimorbidity. Thus, we aimed to identify associations of eczema phenotypes with FA, asthma and hay fever during childhood/adolescence. Additionally, we described the trajectories of eczema, asthma and hay fever stratified by FA presence. METHODS: TRACKER (Trajectories of Allergy in Children in Real Life Databases) is a population-based cohort study of 6852 children/adolescents from the Lifelines cohort. We investigated the associations of seven eczema phenotypes, based on onset age and persistence, with FA, asthma and hay fever using logistic regression, adjusted for appropriate covariates. Disease trajectories were determined by calculating prevalence at different ages. RESULTS: Participants who suffered from eczema throughout childhood showed higher risks of developing FA, hay fever and asthma. "Very early onset-persistent" eczema showed the strongest associations with FA, asthma and hay fever. The prevalence of eczema, asthma and hay fever at all ages was significantly higher in participants with FA, compared to those without. CONCLUSION: One of the largest cohort studies on this topic to date shows that (very) early onset and persistent eczema increases the risk of allergic multimorbidity. Identification of infants at risk for developing (very) early onset eczema is of utmost importance to prevent allergic multimorbidity.

Standardized intermittent shoreline boat electrofishing for slow-flowing rivers in Sweden.

Electrofishing is a common method for sampling fish in rivers. In Sweden, electrofishing has a long history, dating back to the 1950s, but the vast majority of surveys have been conducted by wading in shallow river stretches, leaving a data gap for non-wadable rivers. Boat electrofishing allows for surveys in deeper river sections, but limited numbers of operational electrofishing boats have led to standardisation of methods not being prioritized within Swedish water management. This method protocol describes the first Swedish standardised method for boat electrofishing, based on intermittent shoreline sampling in larger slow-flowing rivers. The paper describes:•General methodology for boat electrofishing operation•Data collection protocols•Discussion of current caveats for the methodIn the future, the methodology will be amended to cover a wider array of river types (e.g. faster flowing river sections). Hence, readers are advised to look for updates to the protocol.

Escherichia coli ST117: exploring the zoonotic hypothesis.

Extraintestinal pathogenic Escherichia coli (ExPEC) can lead to severe infections, with additional risks of increasing antimicrobial resistance rates. Genotypic similarities between ExPEC and avian pathogenic E. coli (APEC) support a possible role for a poultry meat reservoir in human disease. Some genomic studies have been done on the ST117 lineage which contaminates poultry meat, carries multidrug resistance, can be found in the human intestinal microbiota, and causes human extraintestinal disease. This study analyzed the genomes of 61 E. coli from Brazilian poultry outbreaks focusing on ST117, to further define its possible zoonotic characteristics by genotypic and phylogenomic analyses, along with 1,699 worldwide ST117 isolates originating from human, animal, and environment sources. A predominance of ST117 was detected in the Brazilian isolates (n = 20/61) frequently carrying resistance to critical antibiotics (>86%) linked to IncFII, IncI1, or IncX4 replicons. High similarities were found between IncX4 from Brazilian outbreaks and those from E. coli recovered from imported Brazilian poultry meat and human clinical cases. The ST117 phylogeny showed non-specificity according to host and continent and an AMR index score indicated the highest resistance in Asia and South America, with the latter statistically more resistant and overrepresented with resistance to extended-spectrum beta-lactamases (ESBL). Most ST117 human isolates were predicted to have a poultry origin (93%, 138/148). In conclusion, poultry is a likely source for zoonotic ExPEC strains, particularly the ST117 lineage which can also serve as a reservoir for resistance determinants against critical antibiotics encoded on highly transmissible plasmids. IMPORTANCE: Certain extraintestinal pathogenic Escherichia coli (ExPEC) are particularly important as they affect humans and animals. Lineages, such as ST117, are predominant in poultry and frequent carriers of antibiotic resistance, presenting a risk to humans handling or ingesting poultry products. We analyzed ExPEC isolates causing outbreaks in Brazilian poultry, focusing on the ST117 as the most detected lineage. Genomic comparisons with international isolates from humans and animals were performed describing the potential zoonotic profile. The Brazilian ST117 isolates carried resistance determinants against critical antibiotics, mainly on plasmids, in some cases identical to those carried by international isolates. South American ST117 isolates from all sources generally exhibit more resistance, including to critical antibiotics, and worldwide, the vast majority of human isolates belonging to this lineage have a predicted poultry origin. As the world's largest poultry exporter, Brazil has an important role in developing strategies to prevent the dissemination of multidrug-resistant zoonotic ExPEC strains.

Greater exposure to PM2.5 and PM10 was associated with lower corneal nerve measures: the Maastricht study - a cross-sectional study.

BACKGROUND: Epidemiological and toxicological studies indicate that increased exposure to air pollutants can lead to neurodegenerative diseases. To further confirm this relationship, we evaluated the association between exposure to ambient air pollutants and corneal nerve measures as a surrogate for neurodegeneration, using corneal confocal microscopy. METHODS: We used population-based observational cross-sectional data from The Maastricht Study including N = 3635 participants (mean age 59.3 years, 51.6% were women, and 19.9% had type 2 diabetes) living in the Maastricht area. Using the Geoscience and hEalth Cohort COnsortium (GECCO) data we linked the yearly average exposure levels of ambient air pollutants at home address-level [particulate matter with diameters of ≤ 2.5 µm (PM2.5), and ≤ 10.0 µm (PM10), nitrogen dioxide (NO2), and elemental carbon (EC)]. We used linear regression analysis to study the associations between Z-score for ambient air pollutants concentrations (PM2.5, PM10, NO2, and EC) and Z-score for individual corneal nerve measures (corneal nerve bifurcation density, corneal nerve density, corneal nerve length, and fractal dimension). RESULTS: After adjustment for potential confounders (age, sex, level of education, glucose metabolism status, corneal confocal microscopy lag time, inclusion year of participants, smoking status, and alcohol consumption), higher Z-scores for PM2.5 and PM10 were associated with lower Z-scores for corneal nerve bifurcation density, nerve density, nerve length, and nerve fractal dimension [stß (95% CI): PM2.5 -0.10 (-0.14; -0.05), -0.04 (-0.09; 0.01), -0.11 (-0.16; -0.06), -0.20 (-0.24; -0.15); and PM10 -0.08 (-0.13; -0.03), -0.04 (-0.09; 0.01), -0.08 (-0.13; -0.04), -0.17 (-0.21; -0.12)], respectively. No associations were found between NO2 and EC and corneal nerve measures. CONCLUSIONS: Our population-based study demonstrated that exposure to higher levels of PM2.5 and PM10 are associated with higher levels of corneal neurodegeneration, estimated from lower corneal nerve measures. Our results suggest that air pollution may be a determinant for neurodegeneration assessed in the cornea and may impact the ocular surface health as well.

Omentum preservation versus complete omentectomy in gastrectomy for gastric cancer (OMEGA trial): study protocol for a randomized controlled trial.

BACKGROUND: Potentially curative therapy for locally advanced gastric cancer consists of gastrectomy, usually in combination with perioperative chemotherapy. An oncological resection includes a radical (R0) gastrectomy and modified D2 lymphadenectomy; generally, a total omentectomy is also performed, to ensure the removal of possible microscopic disease. However, the omentum functions as a regulator of regional immune responses to prevent infections and prevents adhesions which could lead to bowel obstructions. Evidence supporting a survival benefit of routine complete omentectomy during gastrectomy is lacking. METHODS: OMEGA is a randomized controlled, open, parallel, non-inferiority, multicenter trial. Eligible patients are operable (ASA < 4) and have resectable (≦ cT4aN3bM0) primary gastric cancer. Patients will be 1:1 randomized between (sub)total gastrectomy with omentum preservation distal of the gastroepiploic vessels versus complete omentectomy. For a power of 80%, the target sample size is 654 patients. The primary objective is to investigate whether omentum preservation in gastrectomy for cancer is non-inferior to complete omentectomy in terms of 3-year overall survival. Secondary endpoints include intra- and postoperative outcomes, such as blood loss, operative time, hospital stay, readmission rate, quality of life, disease-free survival, and cost-effectiveness. DISCUSSION: The OMEGA trial investigates if omentum preservation during gastrectomy for gastric cancer is non-inferior to complete omentectomy in terms of 3-year overall survival, with non-inferiority being determined based on results from both the intention-to-treat and the per-protocol analyses. The OMEGA trial will elucidate whether routine complete omentectomy could be omitted, potentially reducing overtreatment. TRIAL REGISTRATION: ClinicalTrials.gov NCT05180864.

Identifying as a Survivor Versus a Victim After Sexual Violence Predicts Divergent Posttrauma Pathways.

The present study investigated social identification with "survivors" versus "victims" following sexual violence and the degree to which this predicted posttraumatic growth versus posttraumatic stress. Participants (N = 290) were adult women who had experienced sexual violence. As predicted, cumulative sexual trauma was positively associated with symptoms of both posttraumatic stress and posttraumatic growth. Further, people who had experienced more cumulative sexual trauma were more likely to identify with victims, which in turn predicted posttraumatic stress. Similarly, people who had experienced more cumulative sexual trauma were also more likely to identify with survivors, and this in turn predicted posttraumatic growth.

Can written prompts help medical residents to accurately monitor their own communication skills and those of others?

In healthcare, effective communication in complex situations such as end of life conversations is critical for delivering high quality care. Whether residents learn from communication training with actors depends on whether they are able to select appropriate information or 'predictive cues' from that learning situation that accurately reflect their or their peers' performance and whether they use those cues for ensuing judgement. This study aimed to explore whether prompts can help medical residents improving use of predictive cues and judgement of communication skills. First and third year Kenyan residents (N = 41) from 8 different specialties were randomly assigned to one of two experimental groups during a mock OSCE assessing advanced communication skills. Residents in the intervention arm received paper predictive cue prompts while residents in the control arm received paper regular prompts for self-judgement. In a pre- and post- test, residents' use of predictive cues and the appropriateness of peer-judgements were evaluated against a pre-rated video of another resident. The intervention improved both the use of predictive cues in self-judgement and peer-judgement. Ensuing accuracy of peer-judgements in the pre- to post-test only partly improved: no effect from the intervention was found on overall appropriateness of judgements. However, when analyzing participants' completeness of judgements over the various themes within the consultation, a reduction in inappropriate judgments scores was seen in the intervention group. In conclusion, predictive cue prompts can help learners to concentrate on relevant cues when evaluating communication skills and partly improve monitoring accuracy. Future research should focus on offering prompts more frequently to evaluate whether this increases the effect on monitoring accuracy in communication skills.

Fungal Peptidomelanin: A Novel Biopolymer for the Chelation of Heavy Metals.

Melanin is an amorphous, highly heterogeneous polymer found across all kingdoms of life. Although the properties of melanin can greatly vary, most forms are insoluble and strongly absorb light, appearing dark brown to black. Here, we describe a water-soluble form of melanin (peptidomelanin) secreted by the spores of Aspergillus niger (strain: melanoliber) during germination. Peptidomelanin is composed of an insoluble L-DOPA core polymer that is solubilized via short, copolymerized heterogeneous peptide chains forming a "corona" with a mean amino acid length of 2.6 ± 2.3. Based on in vitro experiments, we propose a biochemical copolymerization mechanism involving the hydroxylation of tyrosynylated peptides. Peptidomelanin is capable of chelating heavy metals such as lead, mercury, and uranium (as uranyl) in large quantities. Preliminary data indicates that peptidomelanin may have applications for the remediation of heavy metals in situ, including in agricultural settings.

Safety and efficacy of the novel RNA interference therapies for hypertriglyceridemia and mixed hyperlipidemia management: a systematic review and meta-analysis.

BACKGROUND: No meta-analysis has holistically analyzed and summarized the safety and therapeutic efficacy of the newer RNA interference (RNAi) therapies, olezarsen, plozasiran, and zodasiran, in managing conditions associated with hypertriglyceridemia (HTG). METHODS: Randomized controlled trials (RCTs) involving patients with HTG or mixed hyperlipidemia (MHL) receiving either olezarsen, plozasiran, or zodasiran in the intervention arm and a placebo in the control arm were searched through electronic databases. The primary outcome was the safety profile of the drugs studied; secondary outcomes included the percent change from baseline (CFB) in the lipid levels, including triglyceride (TG). RESULTS: Six RCTs with 334 participants were evaluated. Olezarsen, plozasiran, and zodasiran were well-tolerated with no higher risk of serious adverse events or injection-site reactions. After 24 weeks, plozasiran increased alanine aminotransferase and HbA1c more than placebo, although the difference was insignificant at 48 weeks. Plozasiran and zodasiran had little effect on hyperglycemia worsening. Olezarsen increased the likelihood of mild platelet count decreases without clinical harm. At their longest clinical trial follow-up, the highest doses of olezarsen, plozasiran, and zodasiran lowered TG by 55.2%, 50.57%, and 51.2% of baseline levels. All three drugs decreased non-HDL-C and remnant cholesterol. Olezarsen and plozasiran lowered ApoC-III and increased HDL-C, whereas zodasiran reduced HDL-C. Zodasiran decreased LDL-C, whereas olezarsen and plozasiran had no effects on LDL-C. Plozasiran and zodasiran lowered apolipoprotein B, but not olezarsen. CONCLUSION: The newer RNA interference (RNAi) therapies appear safe and have excellent TG-lowering efficacy in patients with HTG and MHL.

Predicting groundwater phosphate levels in coastal multi-aquifers: A geostatistical and data-driven approach.

The groundwater (GW) resource plays a central role in securing water supply in the coastal region of Bangladesh and therefore the future sustainability of this valuable resource is crucial for the area. However, there is limited research on the driving factors and prediction of phosphate concentration in groundwater. In this work, geostatistical modeling, self-organizing maps (SOM) and data-driven algorithms were combined to determine the driving factors and predict GW phosphate content in coastal multi-aquifers in southern Bangladesh. The SOM analysis identified three distinct spatial patterns: K+Na+pH, Ca2+Mg2+NO3-, and HCO3-SO42-PO43-F-. Four data-driven algorithms, including CatBoost, Gradient Boosting Machine (GBM), Long Short-Term Memory (LSTM), and Support Vector Regression (SVR) were used to predict phosphate concentration in GW using 380 samples and 15 prediction parameters. Forecasting accuracy was evaluated using RMSE, R2, RAE, CC, and MAE. Phosphate dissolution and saltwater intrusion, along with phosphorus fertilizers, increase PO43- content in GW. Using input parameters selected by multicollinearity and SOM, the CatBoost model showed exceptional performance in both training (RMSE = 0.002, MAE = 0.001, R2 = 0.999, RAE = 0.057, CC = 1.00) and testing (RMSE = 0.001, MAE = 0.002, R2 = 0.989, RAE = 0.057, CC = 0.998). Na+, K+, and Mg2+ significantly influenced prediction accuracy. The uncertainty study revealed a low standard error for the CatBoost model, indicating robustness and consistency. Semi-variogram models confirmed that the most influential attributes showed weak dependence, suggesting that agricultural runoff increases the heterogeneity of PO43- distribution in GW. These findings are crucial for developing conservation and strategic plans for sustainable utilization of coastal GW resources.

Use of Comparative Genomics To Resolve an Unusual Case of Aminoglycoside Susceptibility in the Melioidosis Pathogen Burkholderia pseudomallei in Bangladesh.

Melioidosis is an emerging tropical infectious disease with a rising global burden caused by the environmental bacterium Burkholderia pseudomallei. It is endemic in Southeast and South Asia, including Bangladesh. A rare aminoglycoside-susceptible B. pseudomallei isolate (Y2019) has recently been reported from a melioidosis patient in Dhaka, Bangladesh. To understand the geographical origins of Y2019, we subjected it and 10 other isolates from Bangladesh to whole-genome sequencing. In a phylogenetic tree with a global set of B. pseudomallei genomes, most Bangladeshi genomes clustered tightly within the Asian clade. In contrast, Y2019 was closely related to ST881 isolates from Sarawak, Malaysian Borneo, a gentamicin-sensitive sequence type, suggesting infection in Borneo. Y2019 also contained the same gentamicin sensitivity conferring nonsynonymous mutation in the drug efflux pump encoding the amrB gene. In the absence of a full travel history, whole-genome sequencing and bioinformatics tools have revealed the likely origin of this rare isolate.
