Impact of Nonmedical Switches From Reference Infliximab to Biosimilars on Disease Control Within a Rheumatology Practice.

Infliximab is an anti-tumor necrosis factor agent used to treat rheumatologic disease. Evidence on the safety of switching to biosimilars and the associated risk factors for flares/loss of disease control within rheumatology is limited. The primary objective is to evaluate nonmedical switches from reference infliximab to biosimilars in rheumatology on risks and level of disease control.

Interbreeding area movement of an adult humpback whale between the east Pacific Ocean and southwest Indian Ocean.

Humpback whales undertake one of the longest known migrations of any mammal. While their migration route generally extends between latitudes, the breeding stocks are longitudinally separated and display high site fidelity to their feeding grounds. While there is an indication of certain breeding stocks overlapping with each other, the current information on the migration routes of humpback whales within the Southern Hemisphere limits our understanding of the extent of this exchange.

Diverse Multinuclear Alkali Metallated (Li, Na, K, Rb, Cs) Family of the 1,3,5-tris-2-aminopyridyl-2,4,6-triethylbenzene Framework.

Literature on Group One organoelement chemistry is dominated by lithium, though sodium and potassium also feature prominently, whereas rubidium and caesium are rarely mentioned. With recent breakthroughs hinting that organoelement compounds of these two heavier metals can perform better than their lighter congeners in particular applications, important advantages could be missed unless complete sets of alkali metals are included in studies. Here, we report the synthesis and characterisation of a complete set of multi-alkali-metallated molecular compounds of the 1,3,5-tris[(4,6-dimethylpyridin-2-yl)aminomethyl]-2,4,6-triethylbenzene framework.

Nephrology providers' perspective and use of mortality prognostic tools in dialysis patients.

Background: Mortality prognostic tools exist to aid in shared decision making with kidney failure patients but are underutilized. This study aimed to elucidate nephrology providers' practice patterns and understand barriers to prognostic tool use.

Methods: Nephrology providers (8 physicians and 2 nurse practitioners) at an academic medical center underwent semi-structured interviews regarding their experience and perspective on the utility of mortality prognostic tools.

Salcaprozate-based ionic liquids for GLP-1 gastric delivery: A mechanistic understanding of in vivo performance.

Oral delivery of peptides requires formulations with high concentrations of permeation enhancer (PE) to promote absorption, and often necessitates fasting time between dosing and food ingestion. Improved formulations promoting a more rapid absorption would increase convenience of use but requires a faster onset of action. We have developed a salcaprozate-based ionic liquid (IL) formulation, namely choline salcaprozate (CHONAC), for oral delivery of a glucagon-like peptide-1 (GLP-1) analogue via gastric absorption.

Through Their Eyes: Using Photovoice to Capture the Capacity-Building Journey of Long Covid Patient Experts.

Background: Long Covid, characterised by persistent symptoms following the coronavirus disease 2019 (COVID-19) infection, significantly impacts the quality of life. Engaging patients in research and care through participatory methods can enhance a shared understanding of illness and improve the relevance of research.

Objective: We define Patient Experts (PEs) as persons (including patients, caregivers and providers) who have completed a series of training sessions on team building, research methods and communication at the Patient Engagement Studio, University of South Carolina (PES USC).

Expediting treatments in the 21st century: orphan drugs and accelerated approvals.

Background: In response to activated patient communities' catalyzation, two significant efforts by the FDA to expedite treatments have now been in place for multiple decades. In 1983, the United States Congress passed the Orphan Drug Act to provide financial incentives for development of drugs for rare diseases. In 1992, partly in response to the HIV epidemic, the FDA implemented Accelerated Approval (AA) to expedite access to promising new therapies to treat serious conditions with unmet medical need based on surrogate marker efficacy while additional clinical data is confirmed.

Toward On-Demand Polymorphic Transitions of Organic Crystals via Side Chain and Lattice Dynamics Engineering.

Controlling polymorphism, namely, the occurrence of multiple crystal forms for a given compound, is still an open technological challenge that needs to be addressed for the reliable manufacturing of crystalline functional materials. Here, we devised a series of 13 organic crystals engineered to embody molecular fragments undergoing specific nanoscale motion anticipated to drive cooperative order-disorder phase transitions. By combining polarized optical microscopy coupled with a heating/cooling stage, differential scanning calorimetry, X-ray diffraction, low-frequency Raman spectroscopy, and calculations (density functional theory and molecular dynamics), we proved the occurrence of cooperative transitions in all the crystalline systems, and we demonstrated how both the molecular structure and lattice dynamics play crucial roles in these peculiar solid-to-solid transformations.

Evaluating acute medical service performance against assessment time metrics: the Society for Acute Medicine Benchmarking Audit 2023 (SAMBA23).

Performance within acute medicine services is impacted by ongoing pressures on acute care services. Data from the Society for Acute Medicine Benchmarking Audit 2023 (SAMBA23), was used to assess performance of acute medicine services compared to key clinical quality indicators, comparing performance by initial assessment location. Data was analysed for 8213 unplanned attendances across 161 hospitals.

The Context of Poverty and Cancer: Denying Human Potential.

Poverty is a carcinogen and a leading cause of cancer disparities and overall mortality in the United States. Poverty is often viewed as an individual failure for "being poor," but in fact, poverty is structurally driven, intergenerational, and place-based that socially deprives and denies human potential. Disparities in timely cancer prevention, diagnosis, treatment, survivorship, and survival disproportionally impact people living in poverty and especially in persistent poverty areas, an extreme form of place-based poverty that affects communities over multiple generations.

Cancer Epidemiology in Hispanic Populations: Needs and Opportunities.

This report provides a summary of the identified evidence gaps and a general discussion of the next steps to advance cancer epidemiology research in Hispanic/Latino (H/L) populations based partly on the workshop, "Cancer Epidemiology in Hispanic Populations," convened by the NCI in September 2021. The cancer burden among H/L populations varies greatly by nativity and country of origin, yet this variation is not often captured due to systemic challenges in how racial/ethnic data have been collected and often reported in aggregate for this heterogeneous population. Developing culturally relevant assessment tools, increasing the representation of H/L participants, and adopting appropriate methodologic approaches are critical to enhancing cancer research.

Characterizing Hematological Changes Following Repeated Exposure to Non-Targeted Low-Dose Ionizing Radiation in Prostate Cancer Patients.

The duration and magnitude of haematological changes following non-targeted low-dose radiation have not been well explored. We previously reported that low-dose radiation (150 mGy 2x/week for 5 consecutive weeks) was well tolerated by participants (n = 15) with minimal toxicities and no changes in quality of life. Leukocytes, platelets and erythrocytes decreased from baseline measurement 12 months following treatment, however changes were not clinically significant.

The role of emotion regulation in decreasing alcohol harm for veterans.

Using the socio-ecological model, this study aims to understand factors associated with alcohol misuse in veterans of the New Zealand Defence Forces, and identify approaches for reducing harm. Using interviews, veterans were asked to recount their relationship to alcohol, and provide a narrative of its use before, during and after military service. Seven themes were identified including bars and drinking as 1) social hubs; and 2) social lubrication; providing others with 3) duty of care; the military 4) consequences of harmful drinking; and use of alcohol as 5) emotion regulation strategies; with the impact of that on 6) Civvy street, and 7) family impacts.

Evidence-based recommendations regarding risk reduction practices for people at risk of or with breast cancer-related lymphedema: consensus from an expert panel.

Several recent studies have investigated the validity of precautionary practices for lymphedema risk reduction after breast cancer treatment, such as avoidance of blood pressure measurements, skin puncture, blood draws, and use of prophylactic compression during air travel. Other studies have elucidated risk factors for breast cancer-related lymphedema, such as axillary lymph node dissection and skin infection (cellulitis). Combining the current evidence base with the consensus opinion of lymphatic experts assembled at the American Cancer Society/Lymphology Association of North America Summit in October 2023, updated evidence-based risk reduction recommendations are presented for those with or at risk of breast cancer-related lymphedema.

ATR inhibition increases reliance on PARP-mediated DNA repair revealing an improved therapeutic strategy for cervical cancer.

Objective: Cervical cancer results from persistent infection with high-risk human papillomavirus (HR-HPV) and the expression of E6 and E7 oncoproteins. E6 and E7 compromise the activity of p53 and Rb, the G1-S cell cycle checkpoint, and ATM-mediated DNA damage repair (DDR), which in turn increases reliance on ATR- and PARP-mediated DDR at the G2 cell cycle checkpoint. This study aimed to determine the effects of an ATR inhibitor (ATRi, AZD6738) and a PARP-inhibitor (PARPi, AZD2281) on HR-HPV+ cervical cancer cell lines.

Understanding the Values, Qualities, and Preferences of Patients in Their Relationships With Obstetrics and Gynecology Providers: Cross-Sectional Survey With a Mixed Methods Approach.

Background: The patient-provider relationship in obstetrics and gynecology (OBGYN) is uniquely complex due to the sensitive nature of examinations and topics. Patients often prefer health care providers who share similar racial, ethnic, gender, or linguistic backgrounds, particularly in sensitive health care situations, to improve communication and comfort, though historically, specific gender preferences for OBGYNs have not been evident.

Objective: This study aims to describe the values, qualities, and preferences of patients in their relationships with OBGYN providers.
