Polygenic Prediction of Weight and Obesity Trajectories from Birth to Adulthood.

Severe obesity is a rapidly growing global health threat. Although often attributed to unhealthy lifestyle choices or environmental factors, obesity is known to be heritable and highly polygenic; the majority of inherited susceptibility is related to the cumulative effect of many common DNA variants. Here we derive and validate a new polygenic predictor comprised of 2.1 million common variants to quantify this susceptibility and test this predictor in more than 300,000 individuals ranging from middle age to birth. Among middle-aged adults, we observe a 13-kg gradient in weight and a 25-fold gradient in risk of severe obesity across polygenic score deciles. In a longitudinal birth cohort, we note minimal differences in birthweight across score deciles, but a significant gradient emerged in early childhood and reached 12 kg by 18 years of age. This new approach to quantify inherited susceptibility to obesity affords new opportunities for clinical prevention and mechanistic assessment.

Association Between Marijuana Use and Clinical Outcomes After Coronary Artery Bypass Grafting.

INTRODUCTION: Though marijuana use has been linked to an increase in heart failure admissions, no prior study has explored the association between its use and outcomes after coronary artery bypass grafting (CABG). This study examines the relationship between marijuana use and postoperative outcomes in CABG patients. METHODS: We utilized data from the National Inpatient Sample database from 2008 to 2018 for CABG patients ≥18 y old. Patients were divided into two groups based on marijuana use (abuse/dependency versus nonuse). Primary outcomes include in-hospital mortality, favorable discharge, and length of stay (LOS). Secondary outcomes include acute kidney injury (AKI), acute myocardial infarction (AMI), and transient ischemic attack (TIA)/stroke. A multivariable model, adjusted for confounding variables, was utilized for each outcome. RESULTS: A total of 343,796 patients met inclusion criteria for the study, 590 of which were marijuana users. In both marijuana user and nonuser groups, most patients were male and White with an average age of 56.0 and 66.3 y, respectively. There was a nonsignificant decreased odds of in-hospital mortality among marijuana users (odds ratio [OR] = 0.41, [0.141-1.124]). Marijuana users exhibited significantly decreased odds of home discharge (OR = 1.50, [1.24-1.81]), and increased odds of longer LOS (mean 10.4 d versus 9.8 d; OR = 1.14, [1.09-1.20]), AKI (OR = 1.40, [1.11-1.78]), AMI (OR = 1.56, [1.32-1.84]), and TIA/stroke (OR = 1.64, [1.21-2.22]). CONCLUSIONS: Marijuana use and dependency are associated with increased nonhome discharge, AKI, AMI, TIA/stroke, and longer LOS. Further studies are needed to delineate the pathophysiologic derangements that contribute to these unfavorable post-CABG outcomes.

Highly Selective C-N and C-S Dual Functionalization of 1,3-Dicarbonyl Derivatives Using TBHP as an Oxidant.

A direct electrosynthesis/photocatalyst-free, atom-economical, and efficient method for the selective synthesis of (E)-3-amino-2-thiocyanato-α,ß-unsaturated carbonyl compounds is described through a given protocol. The present approach features the use of inexpensive ammonium thiocyanate to achieve dual functionalization of 1,3-dicarbonyl compounds using TBHP as an oxidant, providing a rapid and practical route to the selective formation of both C-N and C-S bonds via a radical process. This method offers a broad substrate scope with excellent yield and allows for further exploration of the products to construct heterocyclic compounds and other functionalities.

Reactions to serum eye drops-New Zealand experience and review of the literature.

BACKGROUND: Serum eye drops (SED) are used to treat ocular surface disease. Reactions to SED are poorly documented. METHODS: We present our experience of self-reported reactions in New Zealand to SED (25%; autologous, allogeneic, or both) between 2003 and 2023, and a focused review of the literature. RESULTS: In total, 1067 patients received SED treatment (562 autologous, 318 allogeneic, and 187 both). Three (0.5% of those treated with allogeneic SED) reported reactions. All appeared to be allergic. All were associated with allogeneic SED. We have information on two patients: one had an eye reaction; in the other, the gastrointestinal tract was involved. The literature contains few reports of reactions to SED. They have involved both autologous and allogeneic SED, and various SED concentrations. None appears to have been severe. Notably, no eye or systemic infections have been reported. CONCLUSIONS: Information on the types and frequencies of reactions to SED is poor. This may be due to: serum being less likely to cause reactions; eyes being resistant to reactions; reactions being rare, and insufficient use of SED having occurred; under-reporting related to SED use at home and reactions being mild. More robust monitoring for reactions to SED is needed.

Surgical outcomes and revision rates for velopharyngeal insufficiency (VPI) in syndromic and non-syndromic children: A systematic review and meta-analysis.

PURPOSE: To evaluate pre- and post-operative resonance, surgical technique, revision rate, and revision indication among syndromic and non-syndromic children with velopharyngeal insufficiency (VPI). MATERIALS AND METHODS: A systematic review was conducted through July 2022. Children surgically treated for VPI were included. A meta-analysis of single means, proportions, comparison of proportions, and mean differences with 95 % confidence interval [CI] was conducted. RESULTS: Twenty-three articles (n = 1437) were included in the analysis. The most common surgery was Sphincter Pharyngoplasty (SP), 62.6 % [31.3-88.9] for syndromic and 76.3 % [37.5-98.9] for non-syndromic children. Among all surgical techniques, for syndromic and non-syndromic children, 54.8 % [30.9-77.5] and 73.9 % [61.3-84.6] obtained normal resonance post-operatively, respectively. Syndromic patients obtained normal resonance post-operatively in 83.3 % [57.7-96.6] of Combined Furlow Palatoplasty and Sphincter Pharyngoplasty (CPSP), 72.6 % [54.5-87.5] of Pharyngeal Flap (PF), and 45.1 % [13.2-79.8] of Sphincter Pharyngoplasty (SP) surgeries. Non-syndromic patients obtained normal resonance post-operatively in 79.2 % [66.4-88.8] of PF and 75.2 % [61.8-86.5] of SP surgeries. The revision rate for syndromic and non-syndromic patients was 19.9 % [15.0-25.6] and 11.3 % [5.8-18.3], respectively. The difference was statistically significant, 8.6 % [2.9-15.0, p = 0.003]. Syndromic patients who underwent PF were least likely to undergo revision surgery as compared to SP and CPSP, 7.7 % [2.3-17.9] vs. 23.7 % [15.5-33.1] and 15.3 % [2.8-40.7], respectively. CONCLUSIONS: Syndromic children had higher revision rates and were significantly less likely to obtain normal resonance following primary surgery than non-syndromic patients. Among syndromic children, PF and CPSP have been shown to improve resonance and reduce revision rates more so than SP alone.

Cleft Lip and/or Palate Repair in Children With Hypopituitarism: Analysis of the Kids' Inpatient Database.

OBJECTIVE: Children with hypopituitarism (CwHP) can present with orofacial clefting, frequently in the setting of multiple midline anomalies. Hypopituitarism (HP) can complicate medical and surgical care; the perioperative risk in CwHP during the traditionally lower risk cleft lip and/or palate (CL/P) repair is not well described. The objective of this study is to examine the differences in complications and mortality of CL/P repair in CwHP compared to children without hypopituitarism (CwoHP). DESIGN: A retrospective cross-sectional analysis. SETTING: The 1997 to 2019 Kids' Inpatient Databases (KID). PATIENTS: Children 3 years old and younger who underwent CL/P repair. MAIN OUTCOME MEASURE(S): Complications and mortality. RESULTS: A total of 34 106 weighted cases were analyzed, with 86 having HP. CwHP had a longer length of stay (3.0 days [IQR 2.0-10.0] vs 1.0 day [IQR 1.0-2.0], P < .001) and higher rates of complications and mortality (12.8% vs 2.9%, P < .001) compared to CwoHP. Controlling for demographic factors, CwHP had 6.61 higher odds of complications and mortality than CwoHP (95% CI 3.38-12.94, P < .001). CONCLUSIONS: CwHP can present with a CL/P and other midline defects that can increase the complexity of their care. These data show a significant increase in length of stay, complications, and mortality in CwHP undergoing CL/P repair. Increased multidisciplinary attention and monitoring may be needed for these children peri- and postoperatively, especially if additional comorbidities are present. Further studies on perioperative management in this population are warranted to reduce morbidity and mortality.

A novel benzothiophene incorporated Schiff base acting as a "turn-on" sensor for the selective detection of Serine in organic medium.

A novel fluorogenic sensor N-benzo[b]thiophen-2-yl-methylene-4,5-dimethyl-benzene-1,2-diamine (BTMPD) was synthesized and characterized by using spectroscopic methods including UV-visible, FT-IR, 1H NMR, 13C NMR, and mass spectrometry. The designed fluorescent probe, owing to its remarkable properties, behaves as an efficient turn-on sensor for the sensing of amino acid Serine (Ser). Also, the strength of the probe enhances upon the addition of Ser via charge transfer, and the renowned properties of the fluorophore were duly found. The sensor BTMPD shows incredible execution potential with respect to key performance indicators such as high selectivity, sensitivity, and low detection limit. The concentration change was linear ranging from 5 × 10-8 M to 3 × 10-7 M, which is an indication of the low detection limit of 1.74 ± 0.02 nM under optimal reaction conditions. Interestingly, the Ser addition leads to an increased intensity of the probe at λ = 393 nm which other co-existing species did not. The information about the arrangement and the features of the system and the HOMO-LUMO energy levels was found out theoretically using DFT calculations which is fairly in good agreement with the experimental cyclic voltammetry results. The fluorescence sensing using the synthesized compound BTMPD reveals the practical applicability and its application in real sample analysis.

Racial and Ethnic Disparities in Primary Cleft Lip and Cleft Palate Repair.

OBJECTIVE: To examine the impact of race/ethnicity on timing and postoperative outcomes of primary cleft lip (CL) and cleft palate (CP) repair. DESIGN: Cross-sectional analysis of the National Surgical Quality Improvement Program Pediatric (NSQIP-P) database from 2013 to 2018. PATIENTS AND MAIN OUTCOME MEASURES: Patients under 2 years of age who underwent primary CL or CP repair were identified in the NSQIP-P. Outcomes were the timing of surgery and 30-day readmission and reoperation rates stratified by race and ethnicity. RESULTS: In total, 6021 children underwent CL and 6938 underwent CP repair. Adjusted rates of CL repair over time were 10% lower in Hispanic children (95%CI: 0.84-0.96) and 38% lower for Asian children (95%CI: 0.55-0.70) compared with White infants. CP repair rates over time were 13% lower in Black (95%CI: 0.79-0.95), 17% lower in Hispanic (95%CI: 0.77-0.89), and 53% lower in Asian children (95%CI: 0.43-0.53) than in White infants. Asian patients had the highest rates of delayed surgical repair, with 19.3% not meeting American Cleft Palate-Craniofacial Association (ACPA) guidelines for CL (P < .001) and 28.2% for CP repair (P< .001). Black and Hispanic children had 80% higher odds of readmission following primary CL repair (95%CI: 1.16-2.83 and 95%CI: 1.27-2.61, respectively). CONCLUSIONS: This study of a national database identified several racial/ethnic disparities in primary CL and CP, with reduced receipt of cleft repair over time for non-White children. Asian patients were significantly more likely to have delayed cleft repair per ACPA guidelines. These findings underscore the need to better understand disparities in cleft repair timing and postoperative outcomes.

The First Hybrid International Educational Comprehensive Cleft Care Workshop.

OBJECTIVE: Describe the first hybrid global simulation-based comprehensive cleft care workshop, evaluate impact on participants, and compare experiences based on in-person versus virtual attendance. DESIGN: Cross-sectional survey-based evaluation. SETTING: International comprehensive cleft care workshop. PARTICIPANTS: Total of 489 participants. INTERVENTIONS: Three-day simulation-based hybrid comprehensive cleft care workshop. MAIN OUTCOME MEASURES: Participant demographic data, perceived barriers and interventions needed for global comprehensive cleft care delivery, participant workshop satisfaction, and perceived short-term impact on practice stratified by in-person versus virtual attendance. RESULTS: The workshop included 489 participants from 5 continents. The response rate was 39.9%. Participants perceived financial factors (30.3%) the most significant barrier and improvement in training (39.8%) as the most important intervention to overcome barriers facing cleft care delivery in low to middle-income countries. All participants reported a high level of satisfaction with the workshop and a strong positive perceived short-term impact on their practice. Importantly, while this was true for both in-person and virtual attendees, in-person attendees reported a significantly higher satisfaction with the workshop (28.63 ± 3.08 vs 27.63 ± 3.93; P = .04) and perceived impact on their clinical practice (22.37 ± 3.42 vs 21.02 ± 3.45 P = .01). CONCLUSION: Hybrid simulation-based educational comprehensive cleft care workshops are overall well received by participants and have a positive perceived impact on their clinical practices. In-person attendance is associated with significantly higher satisfaction and perceived impact on practice. Considering that financial and health constraints may limit live meeting attendance, future efforts will focus on making in-person and virtual attendance more comparable.

Perioperative management of acetabular and pelvic fractures: evidence-based recommendations.

PURPOSE: The American Academy of Orthopaedic Surgeons does not currently provide clinical practice guidelines for management of PAF. Accordingly, this article aims to review and consolidate the relevant historical and recent literature in important topics pertaining to perioperative management of PAF. METHODS: A thorough literature review using PubMed, Cochrane and Embase databases was performed to assess preoperative, intraoperative and postoperative management of PAF fracture. Topics reviewed included: time from injury to definitive fixation, the role of inferior vena cava filters (IVCF), tranexamic acid (TXA) use, intraopoperative cell salvage, incisional negative pressure wound therapy (NPWT), intraoperative antibiotic powder use, heterotopic ossification prophylaxis, and pre- and postoperative venous thromboembolism (VTE) prophylaxis. RESULTS: A total of 126 articles pertaining to the preoperative, intraoperative and postoperative management of PAF were reviewed. Articles reviewed by topic include 13 articles pertaining to time to fixation, 23 on IVCF use, 14 on VTE prophylaxis, 20 on TXA use, 10 on cell salvage, 10 on iNPWT 14 on intraoperative antibiotic powder and 20 on HO prophylaxis. An additional eight articles were reviewed to describe background information. Five articles provided information for two or more treatment modalities and were therefore included in multiple categories when tabulating the number of articles reviewed per topic. CONCLUSION: The literature supports the use of radiation therapy for HO prophylaxis, early (< 5 days from injury) surgical intervention and the routine use of intraoperative TXA. The literature does not support the routine use of iNPWT or IVCF. There is inadequate information to make a recommendation regarding the use of cell salvage and wound infiltration with antibiotic powder. While the routine use of chemical VTE prophylaxis is recommended, there is insufficient evidence to recommend the optimal agent and duration of therapy.

SGLT2i as a First-line Antihyperglycemic in the Management of Type 2 Diabetes in the Context of Indians: A Systematic Review and Consensus.

BACKGROUND: Sodium-glucose cotransporter-2 inhibitors (SGLT2i) have been used for almost a decade and have proven to be effective not only in managing Type 2 diabetes (T2D), but their cardio and renal protective features make them very useful in managing patients with risk of multiple comorbidities. This systematic review was undertaken by the authors because there is no evidence currently available in India that has studied the suitability of SGLT2i as a first-line agent in patients newly diagnosed with T2D in India. MATERIALS AND METHODS: First, literature was searched to identify features that are considered important when deciding on a first-line agent for managing T2D. A total of 5 broad topics were identified-glycemic control, extra glycemic effects, antihyperglycemic combination therapy, safety, and cost-effectiveness. These domains had further subheadings, and a total of 16 domains were identified. Metformin is the drug of choice as a first-line agent in such situations and has been considered the gold standard for evaluating the effects of SGLT2i across these domains. A systematic literature review on each domain was conducted to compare SGLT2i with the gold standard in Indian patients newly diagnosed with T2D. Evidence was graded (levels of evidence (LoE)-A, B, and C), and recommendations (class of recommendation (CoR)-I, II, and III) were classified by the expert group as defined in the methodology. RESULTS: According to the systematic reviews conducted, 11 domains had Level A evidence, 2 domains (impact on lipids and gut microbiome) had Level B, and 3 domains had Level C (ß-cell function, renal protection, and glycemic variability) evidence. Based on evidence and expert opinion, the authors recommend SGLT2i as a first-line agent for managing newly diagnosed patients with T2D with a Class I recommendation for 13 domains and Class II for the remaining 3 (impact on lipids, gut microbiome, and ß-cell function). Although a poorer level of evidence (Level C) was available for the glycemic variability domain, the authors still reported this as Class I recommendations according to their expert opinion and consensus. CONCLUSION: This article advocates adopting SGLT2 inhibitors as the primary treatment choice for treating patients with newly diagnosed T2D in India.

Polygenic Scores to Assess Atherosclerotic Cardiovascular Disease Risk: Clinical Perspectives and Basic Implications.

An individual's susceptibility to atherosclerotic cardiovascular disease is influenced by numerous clinical and lifestyle factors, motivating the multifaceted approaches currently endorsed for primary and secondary cardiovascular disease prevention. With growing knowledge of the genetic basis of atherosclerotic cardiovascular disease-in particular, coronary artery disease-and its contribution to disease pathogenesis, there is increased interest in understanding the potential clinical utility of a genetic predictor that might further refine the assessment and management of atherosclerotic cardiovascular disease risk. Rapid scientific and technological advances have enabled widespread genotyping efforts and dynamic research in the field of coronary artery disease genetic risk prediction. In this review, we describe how genomic analyses of coronary artery disease have been leveraged to create polygenic risk scores. We then discuss evaluations of the clinical utility of these scores, pertinent mechanistic insights gleaned, and practical considerations relevant to the implementation of polygenic risk scores in the health care setting.

Transfusion double whammy? Adrenaline-takotsubo-anaphylaxis-Kounis complex post transfusion?

BACKGROUND AND OBJECTIVES: The adrenaline-takotsubo-anaphylaxis-Kounis, or the ATAK complex, where there are clinical and pathophysiological overlaps between takotsubo and Kounis syndromes, in which histaminergic, adrenergic and other mediators may play roles, was recently described. The objective of this report was to describe three cases where the ATAK complex was suspected to have occurred after transfusion. MATERIALS AND METHODS: Three cases were recently reported to the New Zealand Blood Service haemovigilance programme that appeared to have features in common suggestive of the ATAK complex. RESULTS: All three patients had had a blood component transfused, an initial severe allergic reaction, treatment with adrenaline or a congener, subsequent acute left ventricular failure or transfusion-associated circulatory overload, and features suggestive of takotsubo cardiomyopathy. CONCLUSIONS: Although rarely described, transfusion-associated ATAK complex may be occurring more often than believed. Circumstances during a transfusion may predispose to it. It should be suspected if the sequence of events described above occur. Its characteristics need to be better understood. Risk factors for it may be modifiable.

Complete mitochondrial genome of freshwater pearl mussel Lamellidens marginalis (Lamarck, 1819) and its phylogenetic relation within unionidae family.

BACKGROUND: Freshwater mussels play a key role in ecology and are often considered as ecological indicators. Conversely, these molluscs are one of the most threatened groups due to several anthropogenic factors. Knowledge of phylogenetic diversity would assist in formulating effective management and conservation measures. Lamellidens marginalis is one of the most widely used freshwater mussel for pearl production in India. The genomic resources for investigating its evolutionary relationship within the Unionidae family are lacking. METHODS AND RESULTS: In this study, the f-type mitochondrial genome of L. marginalis was sequenced using the Illumina sequencing platform. The length of the mitochondrial genome was 15,732 bp consisting of 23 tRNAs, 2 rRNAs and 13 protein coding genes. The arrangement of genes was UF1 type and gene overlap was observed between trnG and nad1. Comparative analysis with other Unionidae species showed a high divergence rate in nad6 followed by nad2 atp8 and nad5. The phylogenetic tree supported monophyly of the Unioninae subfamily and L. marginalis (Parreysiinae) formed a sister branch to this subfamily. The divergence time of the Parreysiinae from its most recent common ancestor (MRCA) was placed in the Mesozoic era. CONCLUSION: This information will be useful for the understanding the evolutionary pattern of the species of Parreysiinae subfamily.

Placebo and nocebo effects in transfusion medicine.

BACKGROUND: Our own observations suggested that placebo and nocebo effects may occur with transfusions. However these effects seem to have been poorly studied. OBJECTIVES: To examine published information on, and draw attention to the possibility of, placebo and nocebo effects with transfusion. METHODS: Focused literature review. RESULTS: There is some information on placebo effects with clotting factors and this effect appears modest at best. There is very little published information on this regarding other fresh blood components. Although unknown biologic effects cannot be ruled out, there are hints that placebo effects might operate - especially with red blood cell transfusions. There is practically no information on nocebo effects with transfusions. CONCLUSIONS: There are ways of surmounting the practical and ethical difficulties involved, and obtaining better information on both types of effects. Individualised, contextualised, informed consenting of transfusion recipients may help to enhance placebo, and reduce nocebo, effects. This may be supportable ethically, and desirable clinically, and financially.

Crystal structure, DFT studies, Hirshfeld surface and energy framework analysis of 4-(5-nitro-thiophen-2-yl)-pyrrolo [1, 2-a] quinoxaline: A potential SARS-CoV-2 main protease inhibitor.

The title compound 4-(5-nitro-thiophen-2-yl)-pyrrolo[1,2-a] quinoxaline (5NO2TAAPP) was obtained by a straightforward catalyst-free reaction of 5-nitro-2- thiophene carboxaldehyde and 1-(2-aminophenyl) pyrrole in methanol and was structurally characterized by FT IR, UV-Vis, NMR spectroscopic techniques and elemental analysis. The structure of the compound has been confirmed by the single-crystal X-ray diffraction technique. The compound crystallizes in a monoclinic crystal system with space group P21/c. Unit cell dimensions: a = 12.2009(17) A0, b = 8.3544(9) A0, c = 13.9179(17) A0 and ß = 104.980(5) A0. Hirshfeld surface analysis was carried out to understand the different intermolecular interactions. The two-dimensional fingerprint plot revealed the most prominent interactions in the compound. Theoretical calculations were executed using Density functional theory (DFT) by Gaussian09 software to develop optimized geometry and frontier molecular orbital analysis. Molecular docking studies revealed that the title compound is a potent inhibitor of Main protease 3CLpro with PDB ID: 6LU7, the viral protease which is responsible for the new Corona Virus Disease (COVID-19).

Association of Patient Factors and Follow-Up in an International Volunteer Cleft Lip and Palate Repair Clinic in El Salvador.

BACKGROUND: In countries which lack robust health care systems, congenital conditions such as cleft lip and/or palate deformities are often untreated in certain individuals. Many volunteer organizations have stepped in to fill this gap but certain factors, such as continuity of care, are yet to be studied for these clinics. METHODS: This is a retrospective cohort study of 167 pediatric patients with cleft lip and/or palate residing in El Salvador treated by a nongovernmental organizations between 2011 and 2020. This data was used in univariate and multivariable models to associate particular patient factors to their likelihood of following up to their annual clinic visits. RESULTS: Each 1-year increase in duration of follow-up was associated with a 27% decrease in the odds of attending a visit. In addition, 33.7% of cleft lip and 49.7% of cleft palate/cleft lip and palate patients returned at least once. Males had 36% higher odds of attending a return visit compared with females but this difference was not statistically significant. Time spent travelling to the clinic had no effect on follow-up rates. CONCLUSION: Nongovernmental organizations utilizing a diagonal care model should consider using more strategies to maximize continuity of care by increasing communication with patients and emphasizing the need of following up during clinic visits. Continued and increased collaboration with the local team is also of great importance.

Follow-Up Care Barriers for Patients with Orofacial Clefts.

OBJECTIVE: The aim of this study was to evaluate whether a patient with a cleft's age, associated syndrome, cleft phenotype or travel distance affects their follow-up rate. DESIGN: This study is a retrospective review of patients with CL/P treated by a craniofacial clinic. SETTING: The setting was a craniofacial clinic at a tertiary care university hospital. PATIENTS, PARTICIPANTS: Candidates were patients seen by the craniofacial clinic between January 2007 and December 2019. An initial pool of 589 patients was then reduced to 440 due to exclusion criteria. INTERVENTIONS: None. MAIN OUTCOME MEASURE(S): The outcome measure was actual patient attendance to the craniofacial team compared to the team goal expectation of annual return visits. RESULTS: The mean age of participants at the end of the study was 9.0 ± 5.4 years with a mean follow-up period (total possible follow-up period length based on patient age at presentation and study window) of 5.5 ± 3.6 years. There was no association between cleft phenotype, type of syndrome, or distance to the clinic with attendance. Children with syndromes had an 11% decrease in the odds of attending follow-up visits with each 1-year increase in age compared to a 4% decrease in children without syndromes. CONCLUSIONS: The only significant factors determining patient attendance were the presence of a syndrome and increasing age.

Methylene blue removal using raw and modified biomass Plumeria alba (white frangipani) in batch mode: isotherm, kinetics, and thermodynamic studies.

Hazardous dyes used in textile industries are considered high-risk pollutants to the environment. The raw as well as acid-treated Plumeria alba (white frangipani) leaf powder (WFLP and SWFLP) were used for the adsorption of methylene blue (MB) that is available in industrial wastewaters following the batch adsorption technique. The characterizations of adsorbents were done by FTIR, SEM, EDX, TGA, and zeta potential parameters. The adsorption was considered for the effects of temperature, initial dye concentration, solution pH, adsorbent dosage, and contact time. The experimental results obtained in the adsorption of MB were examined by nonlinear error functions like chi-square (χ2), ARE, and MPSD for three isotherm models: Langmuir, Freundlich, and Temkin. The maximum monolayer adsorption capacity, qmax (mg/g), was 45.45 mg/g for raw WFLP and 250 mg/g for SWFLP. The adsorbents fitted to the pseudo-second-order kinetic model (R2 = 0.99) using the experimental data of batch adsorption. The thermodynamic studies explained the spontaneity and nature of adsorption for raw and acid-treated adsorbents. The batch experimental results and characterizations of the adsorbents revealed that the selected adsorbents would be the best adsorbents for the removal of MB from the wastewater solution.

Genetic Association of Albuminuria with Cardiometabolic Disease and Blood Pressure.

Excretion of albumin in urine, or albuminuria, is associated with the development of multiple cardiovascular and metabolic diseases. However, whether pathways leading to albuminuria are causal for cardiometabolic diseases is unclear. We addressed this question using a Mendelian randomization framework in the UK Biobank, a large population-based cohort. We first performed a genome-wide association study for albuminuria in 382,500 individuals and identified 32 new albuminuria loci. We constructed albuminuria genetic risk scores and tested for association with cardiometabolic diseases. Genetically elevated albuminuria was strongly associated with increased risk of hypertension (1.38 OR; 95% CI, 1.27-1.50 per 1 SD predicted increase in albuminuria, p = 7.01 × 10-14). We then examined bidirectional associations of albuminuria with blood pressure which suggested that genetically elevated albuminuria led to higher blood pressure (2.16 mmHg systolic blood pressure; 95% CI, 1.51-2.82 per 1 SD predicted increase in albuminuria, p = 1.22 × 10-10) and that genetically elevated blood pressure led to more albuminuria (0.005 SD; 95% CI 0.004-0.006 per 1 mmHg predicted increase in systolic blood pressure, p = 2.45 × 10-13). These results support the existence of a feed-forward loop between albuminuria and blood pressure and imply that albuminuria could increase risk of cardiovascular disease through blood pressure. Moreover, they suggest therapies that target albuminuria-increasing processes could have antihypertensive effects that are amplified through inhibition of this feed-forward loop.
