Quality by Design in continuous bioprocessing: Investigating the impact of critical process parameters of multi-column chromatography during steady-state and transient phases.

Given the complexities of continuous bioprocessing, it is critical to thoroughly investigate the process parameters unique to multi-column chromatography (MCC) and their potential impacts. However, existing studies have focused on either loading densities or residence time at steady states only, and their combined impact on critical quality attributes (CQAs) especially during transient phases were less known. In this study, we investigated the impact of critical process parameters during both steady-state and transient phases (start-up, close-down, and intermediate perturbation) through full factorial design.

Cultural contexts differentially shape parents' loneliness and wellbeing during the empty nest period.

The coming decades will see a substantial increase in the population of older adults, accompanied by significant demographic and family structure changes worldwide. As a result, the empty nest period-the postparental phase in parents' lives when their children have left home and they are no longer engaged in childrearing-is becoming an increasingly common experience in Western and Asian cultures. The current theoretical review examines the psychological consequences of the empty nest period on loneliness and well-being across cultures, emphasizing the impact of cultural factors on these experiences.

Cryo-EM analysis of Pseudomonas phage Pa193 structural components.

The World Health Organization has designated Pseudomonas aeruginosa as a critical pathogen for the development of new antimicrobials. Bacterial viruses, or bacteriophages, have been used in various clinical settings, commonly called phage therapy, to address this growing public health crisis. Here, we describe a high-resolution structural atlas of a therapeutic, contractile-tailed Pseudomonas phage, Pa193.

Advance Care Planning in Nursing Homes: Comparing Characteristics and Outcomes of Participants and Non-Participants.

Background: There is an increasing need to integrate Advance Care Planning (ACP) in nursing homes (NH) due to rapid aging and burden of multimorbidity. This study examines differences in the characteristics and outcomes of NH residents enrolled in a palliative care programme who have completed ACP and those who did not.

Method: We conducted a retrospective cohort analysis of 294 deceased residents enrolled into a palliative programme from 8 nursing homes in Singapore.

Eating concerns in youth with functional abdominal pain disorders.

Objectives: Adolescents with functional abdominal pain (FAP) often experience pain and other gastrointestinal symptoms in the context of eating, which may place them at risk for eating disorders. This study compared disordered eating and its sequalae in adolescents with FAP to those with chronic headache.

Methods: Participants in this retrospective chart review study were 270 adolescents and young adults (mean age 15.

Biomass specific perfusion rate as a control lever for the continuous manufacturing of biosimilar monoclonal antibodies from CHO cell cultures.

Continuous manufacturing enables high volumetric productivities of biologics such as monoclonal antibodies. However, it is challenging to maintain both high viable cell densities and productivities at the same time for long culture durations. One of the key controls in a perfusion process is the perfusion rate which determines the nutrient availability and potentially controls the cell metabolism.

Antibody glycan quality predicted from CHO cell culture media markers and machine learning.

N-glycosylation can have a profound effect on the quality of mAb therapeutics. In biomanufacturing, one of the ways to influence N-glycosylation patterns is by altering the media used to grow mAb cell expression systems. Here, we explore the potential of machine learning (ML) to forecast the abundances of N-glycan types based on variables related to the growth media.

Associations of Household and Neighborhood Contexts and Hair Cortisol Among Mexican-Origin Adolescents From Low-Income Immigrant Families.

Although neighborhood contexts serve as upstream determinants of health, it remains unclear how these contexts "get under the skin" of Mexican-origin youth, who are disproportionately concentrated in highly disadvantaged yet co-ethnic neighborhoods. The current study examines the associations between household and neighborhood socioeconomic status (SES), neighborhood racial-ethnic and immigrant composition, and hair cortisol concentration (HCC)-a physiological index of chronic stress response-among Mexican-origin adolescents from low-income immigrant families in the United States. A total of 297 (54.

Frailty-aware surgical care: Validation of Hospital Frailty Risk Score (HFRS) in older surgical patients.

Introduction: Frailty has an important impact on the health outcomes of older patients, and frailty screening is recommended as part of perioperative evaluation. The Hospital Frailty Risk Score (HFRS) is a validated tool that highlights frailty risk using 109 International Classification of Diseases, 10th revision (ICD-10) codes. In this study, we aim to compare HFRS to the Charlson Comorbidity Index (CCI) and validate HFRS as a predictor of adverse outcomes in Asian patients admitted to surgical services.

An alternative broad-specificity pathway for glycan breakdown in bacteria.

The vast majority of glycosidases characterized to date follow one of the variations of the 'Koshland' mechanisms to hydrolyse glycosidic bonds through substitution reactions. Here we describe a large-scale screen of a human gut microbiome metagenomic library using an assay that selectively identifies non-Koshland glycosidase activities. Using this, we identify a cluster of enzymes with extremely broad substrate specificities and thoroughly characterize these, mechanistically and structurally.

Body Size Perceptions Associated with Body Mass Index and Weight Loss Intentions Among Two Immigrant Populations.

Background: The rates of obesity among immigrant populations within the USA rise with increasing duration of residency. The aims of this study were to examine weight self-perception and body image discrepancy within a large community sample of Hispanic and Somali predominantly immigrant adults.

Methods: Utilizing a community-based participatory research (CBPR) approach to collect survey data from a sample of adults who self-identified as Hispanic, Latino, or Somali in Southeast Minnesota.

Heterogeneity in Treatment Effect in Posttraumatic Stress Syndrome Trials: A Meta-Regression Analysis.

Objective: To evaluate the heterogeneity in treatment effect in posttraumatic stress disorder (PTSD) trials.

Patients And Methods: We downloaded data from a publicly available repository that captured PTSD trials published from January 1988 through February 2023. We applied restricted maximum-likelihood random-effect meta-analyses and meta-regression to explore potential moderators of treatment effect including methodologic study features (risk of bias domains and control group response rate), characteristics of the population, and intervention features following the theme, intensity, and platform framework.

The Contribution of Psychological Symptoms to Cognitive Difficulties in Youth With Postural Orthostatic Tachycardia Syndrome and Chronic Pain.

Introduction: Subjectively experienced cognitive difficulties are common in youth with postural orthostatic tachycardia syndrome. The pathophysiological and psychological contributions of these cognitive impairments remain unclear.

Method: Participants were 96 adolescents and young adults diagnosed with postural orthostatic tachycardia syndrome and admitted to an intensive pain treatment program.

Screening for eating disorders in adolescents with chronic pain: the Eating Attitudes Test-16-Chronic Pain.

Background: Few measures have been validated to screen for eating disorders (ED) in youth with chronic pain. We conducted confirmatory (CFA) of two established factor structures of the Eating Attitudes Test-26 (EAT-26) in a sample of youth with chronic pain attending an intensive interdisciplinary pain treatment (IIPT) program and examined the validity of the best-fitting model in predicting ED diagnoses in this sample.

Methods: Participants were 880 adolescents (M age = 16.

Mexican-origin adolescents' cumulative strengths predict baseline and longitudinal changes in self-growth outcomes.

This study adopts a cultural ecological perspective to examine how cumulative effects of external transcultural and cultural strengths are related to baseline and changes in three markers of Mexican-origin adolescents' self-growth (i.e., resilience, life meaning, and discipline).

Integrated photocatalysis adsorption processes for oxytetracycline removal: using volborthite and its composite with g-CN.

The photocatalytic-adsorption performance of the composites of volborthite (CuVA) and graphitic carbon nitride (g-CN) was studied in this work using oxytetracycline (OTC) as model pollutant under LED light irradiation. CuVA at different weight percentages (10, 30, 50), namely, C10, C30, and C50, were loaded onto graphitic carbon nitride using wet chemical method. The physical, chemical, and optical properties were evaluated via various analytical techniques.

Differentiating anorexia nervosa and atypical anorexia nervosa with absolute weight cut-offs results in a skewed distribution for premorbid weight among youth.

Objective: Anorexia nervosa (AN) and atypical AN are conceptualized as distinct illnesses, despite similar characteristics and sequelae. Whereas DSM-5 differentiates youth with AN and atypical AN by the presence of clinical 'underweight' (i.e.

Characteristics and outcomes of youth with functional seizures attending intensive interdisciplinary pain treatment.

Functional seizures (FS) can be debilitating and negatively impact quality of life. Yet intervention research for FS is limited, especially for youth. This study examined clinical characteristics and outcomes of youth with FS (13-23 years) presenting to a pediatric intensive interdisciplinary pain treatment (IIPT) program in the midwestern United States.

Feasibility of wearable activity tracking devices to measure physical activity and sleep change among adolescents with chronic pain-a pilot nonrandomized treatment study.

Purpose: Personal informatics devices are being used to measure engagement in health behaviors in adults with chronic pain and may be appropriate for adolescent use. The aim of this study was to evaluate the utilization of a wearable activity tracking device to measure physical activity and sleep among adolescents attending a three-week, intensive interdisciplinary pain treatment (IIPT) program. We also assessed changes in physical activity and sleep from baseline to the treatment phase.

Optimizing treatment environments for trait sensitivity in eating disorders.

Research has identified trait sensitivity as a potential risk factor and treatment target of eating disorders. Conceptualizations of trait sensitivity have depicted individuals with high and low trait sensitivity metaphorically as and , highlighting their responsiveness to environmental conditions and associated outcomes. While require careful tending to survive, with such care, they emerge extraordinary.

Gender Diversity Among Youth Attending an Intensive Interdisciplinary Pain Treatment Program.

Transgender and gender diverse (TGD) youth with chronic pain may be at unique risk for psychological distress and associated functional impairment, yet research on the intersection of chronic pain and gender identity is lacking. In a retrospective chart review of 491 participants admitted to a pediatric intensive interdisciplinary pain treatment (IIPT) program in the midwestern United States over an approximately 4-year period, 6.11% were TGD.

Does embedding pediatric eating disorder treatment in primary care bridge the access gap?

Given the numerous barriers to accessing child and adolescent eating disorder treatment, there is a need for innovation in how this care is delivered. Primary care-based eating disorder treatment has established proof-of-concept, yet it is unclear whether this model can bridge the treatment-access gap. This retrospective chart review study compared demographic and illness characteristics of 106 adolescents (M age = 15.

Disparities in Medical Assessment Practices for Adolescents at Risk for Eating Disorders.

Purpose: The United States Preventative Services Task Force found insufficient evidence to support universal screening for eating disorders (EDs) but did recommend assessing high-risk adolescents through laboratory tests, close follow-up, and referrals to other specialties. Yet, it is unclear whether youth at high risk for EDs receive such assessment and whether patient characteristics influence such practices.

Methods: Using the Rochester Epidemiological Project, we identified adolescents (13-18 years) at risk for EDs (i.
