Polymeric pH-Responsive Metal-Supramolecular Nanoparticles for Synergistic Chemo-Photothermal Therapy.

Stimuli-responsive drug delivery carriers, particularly those exhibiting pH sensitivity, have attracted significant scholarly interest due to their promising potential in anticancer therapeutic applications. This phenomenon can primarily be ascribed to the inherently acidic nature of tumor microenvironments. However, pH-responsive carriers frequently require the incorporation of functional groups or materials sensitive to pH changes. Given the pH-sensitive characteristics of metal coordination with natural small-molecule drugs, organometallic supramolecules present a facile and effective strategy for integrating pH-responsive behavior into these systems. Meanwhile, utilizing the natural compound luteolin in conjunction with iron ions (Fe3+) through the advanced engineering technique of flash nanoprecipitation (FNP) results in the synthesis of stable, highly loaded nanoparticles (NPs) exhibiting a supramolecular photothermal effect. Our experimental findings substantiate that the photothermal effect persists over time, even after the pH-responsive release phase has ended. Consequently, these polymeric pH-responsive metallic supramolecular nanoparticles integrate chemotherapy and photothermal therapy, creating a synergistic approach to cancer treatment. This bifunctional platform, which exhibits both pH-responsive and photothermal properties, presents a highly promising avenue for biomedical applications, particularly in the area of tumor therapies. Its dual function offers a potentially efficacious approach to tumor treatment.

Protection of neutrophils by bone marrow mesenchymal stromal cells is enhanced by tumor-associated inflammatory cytokines.

Mesenchymal stromal/stem cells (MSCs), which are distributed in many tissues including bone marrow, have been reported to play a critical role in tumor development. While bone marrow, the primary site for hematopoiesis, is important for establishing the immune system, whether MSCs in the bone marrow can promote tumor growth via influencing hematopoiesis remains unclear. We observed that the numbers of MSCs and neutrophils were increased in bone marrow in tumor-bearing mice. Moreover, co-culture assay showed that MSCs strongly protected neutrophils from apoptosis and induced their maturation. G-CSF and GM-CSF have been well-documented to be associated with neutrophil formation. We found a remarkably increased level of G-CSF, but not GM-CSF, in the supernatant of MSCs and the serum of tumor-bearing mice. The G-CSF expression can be enhanced with inflammatory cytokines (IFNγ and TNFα) stimulation. Furthermore, we found that IFNγ and TNFα-treated MSCs enhanced their capability of promoting neutrophil survival and maturation. Our results indicate that MSCs display robustly protective effects on neutrophils to contribute to tumor growth in bone niches.

Health-related social needs, medical financial hardship, and mortality risk among cancer survivors.

BACKGROUND: Cancer survivors may face challenges affording food, housing, and other living necessities, which are known as health-related social needs (HRSNs). However, little is known about the associations of HRSNs and mortality risk among adult cancer survivors. METHODS: Adult cancer survivors were identified from the 2013-2018 National Health Interview Survey (NHIS) and linked with the NHIS Mortality File with vital status through December 31, 2019. HRSNs, measured by food insecurity, and nonmedical financial worries (e.g., housing costs), was categorized as severe, moderate, and minor/none. Medical financial hardship, including material, psychological, and behavioral domains, was categorized as 2-3, 1, or 0 domains. Using age as the time scale, the associations of HRSNs and medical financial hardship and mortality risk were assessed with weighted adjusted Cox proportional hazards models. RESULTS: Among cancer survivors 18-64 years old (n = 5855), 25.5% and 18.3% reported moderate and severe levels of HRSNs, respectively; among survivors 65-79 years old (n = 5918), 15.6% and 6.6% reported moderate and severe levels of HRSNs, respectively. Among cancer survivors 18-64 years old, severe HRSNs was associated with increased mortality risk (hazards ratio [HR], 2.00; 95% confidence interval [CI], 1.36-2.93, p < .001; reference = minor/none) in adjusted analyses. Among cancer survivors 65-79 years old, 2-3 domains of medical financial hardship was associated with increased mortality risk (HR, 1.58; 95% CI, 1.13-2.20, p = .007; reference = 0 domain). CONCLUSIONS: HSRNs and financial hardship are associated with increased mortality risk among cancer survivors; comprehensive assessment of HRSN and financial hardship connecting patients with relevant services can inform efforts to mitigate adverse consequences of cancer.

Cancer diagnosis and treatment in working-age adults: Implications for employment, health insurance coverage, and financial hardship in the United States.

The rising costs of cancer care and subsequent medical financial hardship for cancer survivors and families are well documented in the United States. Less attention has been paid to employment disruptions and loss of household income after a cancer diagnosis and during treatment, potentially resulting in lasting financial hardship, particularly for working-age adults not yet age-eligible for Medicare coverage and their families. In this article, the authors use a composite patient case to illustrate the adverse consequences of cancer diagnosis and treatment for employment, health insurance coverage, household income, and other aspects of financial hardship. They summarize existing research and provide nationally representative estimates of multiple aspects of financial hardship and health insurance coverage, benefit design, and employee benefits, such as paid sick leave, among working-age adults with a history of cancer and compare them with estimates among working-age adults without a history of cancer from the most recently available years of the National Health Interview Survey (2019-2021). Then, the authors identify opportunities for addressing employment and health insurance coverage challenges at multiple levels, including federal, state, and local policies; employers; cancer care delivery organizations; and nonprofit organizations. These efforts, when informed by research to identify best practices, can potentially help mitigate the financial hardship associated with cancer.

Effects of Acupuncture Combined with Yi Qi Yang Yin and Blood Activating Formula on Blood Glucose and Renal Function in Early Diabetic Nephropathy: A Randomized Controlled Trial.

Objective: To study the effects of acupuncture combined with the formula of Yi Qi Yang Yin and blood activating (A-YBF) on blood glucose levels and renal function in patients with early diabetic nephropathy. Methods: 96 patients with early diabetic nephropathy treated in our hospital from April 2021 to April 2022 were included in the study and divided into the control group (conventional medical treatment) and the study group (A-YBF), with 48 cases in each group. The efficacy and adverse effects were recorded by comparing the Chinese medicine symptom points, blood glucose level, renal function, and inflammatory factor level between the two groups before and after the treatment. Results: The clinical efficacy of the study group was significantly higher than that of the control group (P < .05). Before treatment, no difference was found between the primary and secondary symptom scores of the two groups (P > .05); after treatment, the primary and secondary symptom scores of the study group were lower than those of the control group (P < .05). Before treatment, there was no difference in fasting blood glucose (FPG) and 2h postprandial glucose (2hPG) levels; 24h urine protein quantification, cystatin C (Cys-C), urinary albumin excretion rate (UAER), and estimated glomerular filtration rate (eGFR) levels; and growth differentiation factor-15 (GDF-15), interleukin-1ß (IL-1ß), interleukin-17 (IL-17), and serum amyloid A (SAA) levels between the two groups (P > .05). After treatment, FPG and 2hPG levels; 24h urine protein quantification, Cys-C and UAER levels; and GDF-15, IL-1ß, IL-17, and SAA levels were lower in the study group than in the control group, while eGFR levels were higher than those in the control group (P < .05). Conclusion: A-YBF can effectively reduce blood glucose levels and improve renal function in patients with early diabetic nephropathy and can be promoted in clinical application.

Quantitative assessment whole-rock iron content in magnetite protolith based on terahertz time-domain spectroscopy.

Terahertz time-domain spectroscopy was first used to establish a correlation with the whole-rock iron (TFe) content in different depths of the Bayan Obo protolith. Compared with element content obtained by the traditional method of X-ray fluorescence spectroscopy (XRF), a similar tendency of the absorption coefficient and refractive index is presented. Furthermore, three machine learning algorithms, namely, partial least squares regression (PLSR), random forest (RF), and multi-layer perceptron (MLP), were used to develop a quantitative analytical model for TFe content of the protolith minerals. Among the three algorithms, MLP has the highest detection accuracy, with a model coefficient of determination R 2 reaching up to 0.945. These findings demonstrate that terahertz time-domain spectroscopy can be used to rapidly quantify the TFe elemental content of protolith, providing a method of detecting the content of mineral components.

Associations of Medical Debt With Health Status, Premature Death, and Mortality in the US.

Importance: Medical debt is increasingly common in the US. Little is known regarding its association with population health. Objective: To examine the associations of medical debt with health status, premature death, and mortality at the county level in the US. Design, Setting, and Participants: This cross-sectional study was conducted at the US county level using 2018 medical debt data from the Urban Institute Debt in America project linked with 2018 data on self-reported health status and premature death from the County Health Rankings & Roadmaps and with 2015 to 2019 mortality data from the National Center for Health Statistics. Data analysis was performed from August 2022 to May 2023. Exposure: Share of population with any medical debt in collections and median amount of medical debt. Main Outcomes and Measures: Health status was measured as (1) the mean number of physically and mentally unhealthy days in the past 30 days per 1000 people, (2) the mean number of premature deaths measured as years of life lost before age 75 years per 1000 people, and (3) age-adjusted all-cause and 18 cause-specific mortality rates (eg, malignant cancers, heart disease, and suicide) per 100 000 person-years. Multivariable linear models were fitted to estimate the associations between medical debt and health outcomes. Results: A total of 2943 counties were included in this analysis. The median percentage of the county population aged 65 years or older was 18.3% (IQR, 15.8%-20.9%). Across counties, a median 3.0% (IQR, 1.2%-11.9%) of the population were Black residents, 4.3% (IQR, 2.3%-9.7%) were Hispanic residents, and 84.5% (IQR, 65.7%-93.3%) were White residents. On average, 19.8% (range, 0%-53.6%) of the population had medical debt. After adjusting for county-level sociodemographic characteristics, a 1-percentage point increase in the population with medical debt was associated with 18.3 (95% CI, 16.3-20.2) more physically unhealthy days and 17.9 (95% CI, 16.1-19.8) more mentally unhealthy days per 1000 people during the past month, 1.12 (95% CI, 1.03-1.21) years of life lost per 1000 people, and an increase of 7.51 (95% CI, 6.99-8.04) per 100 000 person-years in age-adjusted all-cause mortality rate. Associations of medical debt and elevated mortality rates were consistent for all leading causes of death, including cancer (1.12 [95% CI, 1.02-1.22]), heart disease (1.39 [95% CI, 1.21-1.57]), and suicide (0.09 [95% CI, 0.06-0.11]) per 100 000 person-years. Similar patterns were observed for associations between the median amount of medical debt and the aforementioned health outcomes. Conclusions and Relevance: These findings suggest that medical debt is associated with worse health status, more premature deaths, and higher mortality rates at the county level in the US. Therefore, policies increasing access to affordable health care, such as expanding health insurance coverage, may improve population health.

Effects of alendronate on cartilage lesions and micro-architecture deterioration of subchondral bone in patellofemoral osteoarthritic ovariectomized rats with patella-baja.

BACKGROUND: Patellofemoral osteoarthritis (PFJOA) is a subtype of knee OA, which is one of the main causes of anterior knee pain. The current study found an increased prevalence of OA in postmenopausal women, called postmenopausal OA. Therefore, we designed the ovariectomized rat model of patella baja-induced PFJOA. Alendronate (ALN) inhibits osteoclast-mediated bone loss, and has been reported the favorable result of a potential intervention option of OA treatment. However, the potential effects of ALN treatment on PFJOA in the ovariectomized rat model are unknown and need further investigation prior to exploration in the clinical research setting. In this study, the effects of ALN on articular cartilage degradation and subchondral bone microstructure were assessed in the ovariectomized PFJOA rat model for 10 weeks. METHODS: Patella baja and estrogen withdrawal were induced by patellar ligament shortening (PLS) and bilateral ovariectmomy surgeries in 3-month-old female Sprague-Dawley rats, respectively. Rats were randomly divided into five groups (n = 8): Sham + V; OVX + V, Sham + PLS + V, OVX + PLS + V, OVX + PLS + ALN (ALN: 70 µg/kg/week). Radiography was performed to evaluate patellar height ratios, and the progression of PFJOA was assessed by macroscopic and microscopic analyses, immunohistochemistry and micro-computed tomography (micro-CT). RESULTS: Our results found that the patella baja model prepared by PLS can successfully cause degeneration of articular cartilage and subchondral bone, resulting in changes of PFJOA. OVX caused a decrease in estrogen levels in rats, which aggravated the joint degeneration caused by PFJOA. Early application of ALN can delay the degenerative changes of articular cartilage and subchondral bone microstructure in castrated PFJOA rat to a certain extent, improve and maintain the micrometabolism and structural changes of cartilage and subchondral bone. CONCLUSION: The early application of ALN can delay the destruction of articular cartilage and subchondral bone microstructure in castrated PFJOA rat to a certain extent.

COVID-19 vaccination, infection, and symptoms among cancer survivors in the United States.

The experiences of cancer survivors with the COVID-19 pandemic in the United States during 2021 and 2022, when vaccinations became widely available, are largely undocumented. Using nationally representative survey data in 2021 and 2022, we found that compared with adults without a cancer history, cancer survivors were more likely to have at least 2 COVID-19 vaccines (2021: 66.6% vs 62.3%, P = .003; 2022: 77.0% vs 72.4%, P < .001) and as likely to have a COVID-19 infection history (2021: 14.1% vs 14.2%, P = .93; 2022: 39.9% vs 39.3%, P = .55) but, once infected, were more likely to develop moderate to severe symptoms (2021: 62.5% vs 54.2%, P = .02; 54.5% vs 61.3%; P = .13). Among cancer survivors, younger age, lower educational attainment, lack of health insurance, and more comorbidities were statistically significantly associated with lower vaccination rates (P < .001). Among infected cancer survivors, being female and younger were associated with higher likelihood of developing moderate to severe symptoms (P < .001). Our findings suggest tailored efforts to prevent and control COVID-19 infections for cancer survivors.

SOD2 promotes the immunosuppressive function of mesenchymal stem cells at the expense of adipocyte differentiation.

The potent immunomodulatory function of mesenchymal stem/stromal cells (MSCs) elicited by proinflammatory cytokines IFN-γ and TNF-α (IT) is critical to resolve inflammation and promote tissue repair. However, little is known about how the immunomodulatory capability of MSCs is related to their differentiation competency in the inflammatory microenvironment. In this study, we demonstrate that the adipocyte differentiation and immunomodulatory function of human adipose tissue-derived MSCs (MSC(AD)s) are mutually exclusive. Mitochondrial reactive oxygen species (mtROS), which promote adipocyte differentiation, were decreased in MSC(AD)s due to IT-induced upregulation of superoxide dismutase 2 (SOD2). Furthermore, knockdown of SOD2 led to enhanced adipogenic differentiation but reduced immunosuppression capability of MSC(AD)s. Interestingly, the adipogenic differentiation was associated with increased mitochondrial biogenesis and upregulation of peroxisome proliferator-activated receptor gamma coactivator-1 alpha (PPARGC1A/PGC-1α) expression. IT inhibited PGC-1α expression and decreased mitochondrial mass but promoted glycolysis in an SOD2-dependent manner. MSC(AD)s lacking SOD2 were compromised in their therapeutic efficacy in DSS-induced colitis in mice. Taken together, these findings indicate that the adipogenic differentiation and immunomodulation of MSC(AD)s may compete for resources in fulfilling the respective biosynthetic needs. Blocking of adipogenic differentiation by mitochondrial antioxidant may represent a novel strategy to enhance the immunosuppressive activity of MSCs in the inflammatory microenvironment.

Incarceration History and Access to and Receipt of Health Care in the US.

Importance: People with a history of incarceration may experience barriers in access to and receipt of health care in the US. Objective: To examine the associations of incarceration history and access to and receipt of care and the contribution of modifiable factors (educational attainment and health insurance coverage) to these associations. Design, Setting, and Participants: Individuals with and without incarceration history were identified from the 2008 to 2018 National Longitudinal Survey of Youth 1979 cohort. Analyses were conducted from October 2022 to December 2023. Main Measures and Outcomes: Access to and receipt of health care were measured as self-reported having usual source of care and preventive service use, including physical examination, influenza shot, blood pressure check, blood cholesterol level check, blood glucose level check, dental check, and colorectal, breast, and cervical cancer screenings across multiple panels. To account for the longitudinal study design, we used the inverse probability weighting method with generalized estimating equations to evaluate associations of incarceration history and access to care. Separate multivariable models examining associations between incarceration history and receipt of each preventive service adjusted for sociodemographic factors; sequential models further adjusted for educational attainment and health insurance coverage to examine their contribution to the associations of incarceration history and access to and receipt of health care. Results: A total of 7963 adults with 41 614 person-years of observation were included in this study; of these, 586 individuals (5.4%) had been incarcerated, with 2800 person-years of observation (4.9%). Compared with people without incarceration history, people with incarceration history had lower percentages of having a usual source of care or receiving preventive services, including physical examinations (69.6% vs 74.1%), blood pressure test (85.6% vs 91.6%), blood cholesterol level test (59.5% vs 72.2%), blood glucose level test (61.4% vs 69.4%), dental check up (51.1% vs 66.0%), and breast (55.0% vs 68.2%) and colorectal cancer screening (65.6% vs 70.3%). With additional adjustment for educational attainment and health insurance, the associations of incarceration history and access to care were attenuated for most measures and remained statistically significant for measures of having a usual source of care, blood cholesterol level test, and dental check up only. Conclusions and Relevance: The results of this survey study suggest that incarceration history was associated with worse access to and receipt of health care. Educational attainment and health insurance may contribute to these associations. Efforts to improve access to education and health insurance coverage for people with an incarceration history might mitigate disparities in care.

Importance of Patient Health Insurance Coverage and Out-of-Pocket Costs for Genomic Testing in Oncologists' Treatment Decisions.

PURPOSE: Use of genomic testing, especially multimarker panels, is increasing in the United States. Not all tests and related treatments are covered by health insurance, which can result in substantial patient out-of-pocket (OOP) costs. Little is known about oncologists' treatment decisions with respect to patient insurance coverage and OOP costs for genomic testing. METHODS: We identified 1,049 oncologists who used multimarker tumor panels from the 2017 National Survey of Precision Medicine in Cancer Treatment. Separate multivariable ordinal logistic regressions examined associations of oncologist-, practice-, and area-level characteristics and oncologists' ratings of importance (very, somewhat, or a little/not important) of insurance coverage and OOP costs for genomic testing in treatment decisions, adjusting for oncologist years of experience, sex, race and ethnicity, specialty, use of next-generation sequencing (NGS) tests, region, tumor boards, patient insurance mix, and area-level socioeconomic characteristics. RESULTS: Among oncologists, 47.3%, 32.7%, and 20.0% reported that patient insurance coverage for genomic testing was very, somewhat, or a little/not important, respectively, in treatment decisions. In addition, 56.9%, 28.0%, and 15.2% reported that OOP costs for testing were very, somewhat, or a little/not important, respectively. In adjusted analyses, oncologists who used NGS tests were more likely to report patient insurance and OOP costs as important (odds ratio [OR], 2.00 [95% CI, 1.16 to 3.45] and OR, 2.12 [95% CI, 1.22 to 3.68], respectively) in treatment decisions compared with oncologists who did not use these tests, as were oncologists who treated solid tumors, rather than only hematological cancers. More years of experience and higher percentages of Medicaid or self-paid/uninsured patients in the practice were associated with reporting insurance coverage (OR, 1.43 [95% CI, 1.09 to 1.89]) and OOP costs (OR, 1.51 [95% CI, 1.13 to 2.01]) as important. Oncologists in practices with molecular tumor boards for genomic tests were less likely to report coverage (OR, 0.63 [95% CI, 0.47 to 0.85]) and OOP costs (OR, 0.72 [95% CI, 0.53 to 0.97]) as important than their counterparts in practices without these tumor boards. CONCLUSION: Most oncologists rate patient health insurance and OOP costs for genomic tests as important considerations in subsequent treatment recommendations. Modifiable factors associated with these ratings can inform interventions to support patient-physician decision making about care.

Employment and workdays lost among spouses of cancer survivors: Intersection with gender across cancer treatment status.

BACKGROUND: Cancer patients and survivors have high care needs, often provided by a spouse or partner. The purpose of this study was to elucidate how employment and work loss patterns differed across cancer history/treatment status and gender. METHODS: Using nationally representative data from the Medical Expenditure Panel Survey (2011, 2016, and 2017), the authors linked data across married participants and categorized them by spouses' cancer treatment status (no cancer history, on treatment for cancer, off treatment for cancer). Multivariable logistic and zero-inflated negative binomial regressions were used to assess the associations among cancer history/treatment status, gender, and employment outcomes (employment status and workdays lost to care for self or others). RESULTS: For men, employment did not differ significantly by cancer history/treatment status (on treatment: odds ratio [OR], 0.58; 95% confidence interval [CI], 0.33-1.02, off treatment: OR, 0.84; 95% CI, 0.62-1.14 vs. no cancer history). For women, employment was not significantly different when the spouse was on treatment for cancer compared to no cancer history (OR, 0.78; 95% CI, 0.33-1.86]) but was significantly increased for women whose spouse was off treatment (OR, 1.39; 95% CI, 1.05-1.84). Among employed participants, women whose spouse was on cancer treatment were nine times more likely to take days off work to provide care (OR, 9.52; 95% CI, 3.94-23.03) and took more than three times as many days off to care for others (OR, 3.21; 95% CI, 2.07-4.97) as men whose spouse had no cancer history. CONCLUSIONS: Wives of cancer survivors are at increased risk of work loss, with implications for their financial and psychological well-being. Employers, policymakers, and clinicians have opportunities to support working caregivers.

Financial hardship among siblings of long-term survivors of childhood cancer: A Childhood Cancer Survivor Study report.

BACKGROUND: Siblings of children with cancer may experience adverse household economic consequences, but their financial outcomes in adulthood are unknown. METHODS: A total of 880 siblings (aged 18-64 years) of adult-aged childhood cancer survivors were surveyed to estimate the prevalence of financial hardship by three established domains (behavioral, material, and psychological). For individual financial hardship items matching the contemporaneous National Health Interview Survey or Behavioral Risk Factor Surveillance System, siblings were compared with the general population by calculating adjusted prevalence odds ratios (ORs) to sample-weighted responses. Multivariable logistic regression models examined associations between sibling characteristics and each hardship domain and between sibling hardship and survivors' cancer/treatment characteristics. RESULTS: Behavioral, material, and psychological hardship was reported by 24%, 35%, and 28%, respectively. Compared with national survey respondents, siblings were more likely to report worries about medical bills (OR, 1.14; 95% confidence interval [CI], 1.06-1.22), difficulty affording nutritious foods (OR, 1.79; 95% CI, 1.54-2.07), and forgoing needed medical care (OR, 1.38; 95% CI, 1.10-1.73), prescription medications (OR, 2.52; 95% CI, 1.99-3.20), and dental care (OR, 1.34; 95% CI, 1.15-1.57) because of cost. Sibling characteristics associated with reporting financial hardship in one or more domains included female sex, older age, chronic health conditions, lower income, not having health insurance, high out-of-pocket medical expenditures, and nonmedical/nonhome debt. No survivor cancer/treatment characteristics were associated with sibling financial hardship. CONCLUSIONS: Adult siblings of childhood cancer survivors were more likely to experience financial hardship compared with the general population. Childhood cancer may adversely affect entire households, with potentially lasting implications.

Health-related quality of life among prostate cancer survivors with metastatic disease and non-metastatic disease and men without a cancer history in the USA.

BACKGROUND: Few studies have comprehensively compared health-related quality of life (HRQoL) between metastatic prostate cancer survivors, survivors with non-metastatic disease, and men without a cancer history. METHODS: We used the Surveillance, Epidemiology, and End Results-Medicare Health Outcomes Survey (SEER-MHOS) data linkage to identify men aged ≥ 65 years enrolled in Medicare Advantage (MA) plans. Prostate cancer survivors were diagnosed between 1988 and 2017 and completed MHOS surveys between 1998 and 2019. We analyzed data from 752 metastatic prostate cancer survivors (1040 survey records), 19,583 localized or regional prostate cancer survivors (non-metastatic; 30,121 survey records), and 784,305 men aged ≥ 65 years without a cancer history in the same SEER regions (1.15 million survey records). We used clustered linear regressions to compare HRQoL measures at the person-level using the Veterans RAND 12 Item Health Survey (VR-12) T-scores for general health and physical and mental component summaries. RESULTS: Compared to men without a cancer history, prostate cancer survivors were older, more likely to be married, and had higher socioeconomic status. Compared to men without a cancer history, metastatic prostate cancer survivors reported lower general health (T-score differences [95% confidence interval]: - 6.26, [- 7.14, - 5.38], p < .001), physical health (- 4.33, [- 5.18, - 3.48], p < .001), and mental health (- 2.64, [- 3.40, - 1.88], p < .001) component summaries. Results were similar for other VR-12 T-scores. In contrast, non-metastatic prostate cancer survivors reported similar VR-12 T-scores as men without a cancer history. Further analyses comparing metastatic and non-metastatic prostate cancer survivors support these findings. CONCLUSION: Interventions to improve health-related quality of life for men diagnosed with metastatic prostate cancer merit additional investigation. IMPLICATIONS FOR CANCER SURVIVORS: Interventions to improve health-related quality of life for metastatic prostate cancer survivors merit additional investigation.

Association of Employment Disruptions and Financial Hardship Among Individuals Diagnosed with Cancer in the United States: Findings from a Nationally Representative Study.

Financial hardship (FH), defined as adverse patient effects due to cancer costs, is experienced by approximately half of individuals diagnosed with cancer. Many individuals diagnosed with cancer also experience disruptions with their employment. This study examines associations of employment disruptions and FH among a nationally representative sample of individuals diagnosed with cancer in the United States. We utilized 2016/2017 Medical Expenditure Panel Survey Experiences with Cancer data from individuals who worked for pay following cancer diagnosis. Employment disruption included taking extended paid time off work; switching to part-time/less demanding jobs; and/or retiring early due to cancer diagnosis/treatment. FH domains included: material (e.g., borrowing money/financial sacrifices); psychologic (e.g., worrying about medical bills/income); and behavioral (delaying/forgoing healthcare services because of cost). Multivariable logistic regression analyses determined associations of employment disruption and FH. Among 732 individuals with a cancer history, 47.4% experienced employment disruptions; 55.9% experienced any FH. Any FH was significantly more common among individuals with versus without employment disruptions across multiple measures and domains (68.7% vs. 44.5%; P value of difference <0.0001). Individuals with employment disruptions were more likely to have any FH [OR, 2.38; 95% confidence interval (CI), 1.62-3.52] and more FHs (OR, 2.76; 95% CI, 1.96-3.89]. This study highlights that employment disruptions are common and significantly associated with multiple domains of FH among individuals with a cancer history. Employer workplace accommodation, physician discussions regarding potential impacts of cancer care on employment, and other policies to minimize employment disruptions among individuals diagnosed with cancer may reduce FH in this vulnerable population. Significance: Individuals diagnosed with cancer may have employment disruptions; they may also develop FHs. People with cancer who have employment changes are more likely to also have FHs. Physicians and employers can help individuals with cancer through advancing planning, workplace assistance, and improved medical leave and insurance policies.

Hydrogen-Bonded Organic Frameworks Chelated Manganese for Precise Magnetic Resonance Imaging Diagnosis of Cancers.

Magnetic resonance imaging (MRI) is an important tool in the diagnosis of many cancers. However, clinical gadolinium (Gd)-based MRI contrast agents have limitations, such as large doses and potential side effects. To address these issues, we developed a hydrogen-bonded organic framework-based MRI contrast agent (PFC-73-Mn). Due to the hydrogen-bonded interaction of water molecules and the restricted rotation of manganese ions, PFC-73-Mn exhibits high longitudinal relaxation r1 (5.03 mM-1 s-1) under a 3.0 T clinical MRI scanner. A smaller intravenous dose (8 µmol of Mn/kg) of PFC-73-Mn can provide strong contrast and accurate diagnosis in multiple kinds of cancers, including breast tumor and ultrasmall orthotopic glioma. PFC-73-Mn represents a prospective new approach in tumor imaging, especially in early-stage cancer.

Investigation of the Therapeutic Effect and Mechanism of Holographic Meridian Scraping Therapy on Knee Osteoarthritis.

Objective: This study aimed to investigate the efficacy of holographic meridian scraping therapy on patients with knee osteoarthritis (KOA) and its impact on serum IL-1ß and TNF-α levels. Methods: A prospective study was conducted, enrolling seventy KOA patients admitted to the Hebei Provincial Hospital of Traditional Chinese Medicine between August 2021 and April 2022. The patients were divided into two groups using the random number table method: control group (n = 35) and treatment group (n = 35). The control group received oral celecoxib capsules (100 mg, twice daily), while the treatment group received an additional daily holographic meridian scraping session (20 minutes/day). Throughout the two-week study, the researchers continuously monitored the visual analogue scale (VAS) score, the Western Ontario and McMaster Universities Arthritis Index (WOMAC) score, and the changes in serum IL-1ß and TNF-α expression. Results: The treatment group demonstrated significantly better overall efficiency and efficacy compared to the control group (P < .05). Both groups exhibited decreased VAS and WOMAC scores after treatment in comparison to pre-treatment levels (P < .05), with the treatment group showing lower scores than the control group after treatment (P < .05). Furthermore, serum TNF-α and IL-1ß levels in both groups decreased after treatment compared to pre-treatment levels within the same group (P < .05). The treatment group had significantly lower serum TNF-α and IL-1ß levels than the control group after treatment (P < .05). Conclusions: Combining holographic meridian scraping therapy with celecoxib effectively treats KOA and significantly improves patient conditions, along with reductions in serum TNF-α and IL-1ß levels.

Parental Cancer History and Its Association With Minor Children's Unmet Food, Housing, and Transportation Economic Needs.

Importance: A cancer diagnosis is associated with substantial economic burden for patients and their families. Young adult cancer survivors with dependent children may be particularly vulnerable to financial hardship. Objective: To examine associations of parental cancer with their children's unmet economic needs. Design, Setting, and Participants: This cross-sectional study used data from the nationally representative 2013 to 2018 US National Health Interview Survey. Children aged 5 to 17 years living in families with and without parental cancer history were queried about recent 1-year experiences. Statistical analyses were conducted from January 2022 to April 2023. Exposure: Parental cancer history. Main Outcomes and Measures: The main outcomes were children's unmet economic needs, including family-level food insecurity, parent's financial worry about paying for monthly bills and housing costs, and delayed child medical care owing to lack of transportation. Multivariable logistic regressions adjusted for (1) child's characteristics (ie, age group, sex, and race and ethnicity), (2) parent's characteristics (ie, age group, sex, health insurance coverage, comorbid conditions, and obesity status), and (3) family's characteristics (ie, family structure [married or cohabiting parents vs single parent families], highest educational attainment in the family, and family income). Additional analyses focused on children with a parental cancer history to identify potentially modifiable characteristics associated with unmet economic needs. Results: In this cross-sectional study of 22 941 children with (812 children; weighted number, 860 488 children) and without (22 129 children; weighted number, 24 545 463 children) a parental cancer history, the majority of children were aged 5 to 11 years (12 022 children [52.4%]), male (11 920 children [52.0%]), and non-Hispanic White (11 863 children [51.7%]). In adjusted analyses, parental cancer history was associated with more severe family-level food insecurity, including worrying about food running out (odds ratio [OR], 1.97; 95% CI, 1.56-2.49; P < .001), food not lasting (OR, 2.01; 95% CI, 1.56-2.58; P < .001), and inability to afford balanced meals (OR, 1.38; 95% CI, 1.06-1.79; P = .02). Moreover, parental cancer history was associated with parent's worry about paying monthly bills (OR, 1.41; 95% CI, 1.15-1.74; P = .001) and housing-related costs (OR, 1.31; 95% CI, 1.07-1.60; P = .009) and delays in child medical care because of lack of transportation (OR, 2.31; 95% CI, 1.49-3.59; P < .001). Among children with parental cancer history, female children, non-Hispanic Black children, children whose parents had multiple comorbidities, and children living in low-income families were especially vulnerable to unmet economic needs. Conclusions and Relevance: Parental cancer is associated with greater likelihood of food insecurity, unaffordability of housing and other necessities, and transportation barriers to medical care for minor children. Strategies to identify such children and address their needs are warranted.
