The effect of COVID-19 on cancer incidences in the U.S.

Fundamental data analysis assists in the evaluation of critical questions to discern essential facts and elicit formerly invisible evidence. In this article, we provide clarity into a subtle phenomenon observed in cancer incidences throughout the time of the COVID-19 pandemic. We analyzed the cancer incidence data from the American Cancer Society [1]. We partitioned the data into three groups: the pre-COVID-19 years (2017, 2018), during the COVID-19 years (2019, 2020, 2021), and the post-COVID-19 years (2022, 2023). In a novel manner, we applied principal components analysis (PCA), computed the angles between the cancer incidence vectors, and then added lognormal probability concepts in our analysis. Our analytic results revealed that the cancer incidences shifted within each era (pre, during, and post), with a meaningful change in the cancer incidences occurring in 2020, the peak of the COVID-19 era. We defined, computed, and interpreted the exceedance probability for a cancer type to have 1000 incidences in a future year among the breast, cervical, colorectal, uterine corpus, leukemia, lung & bronchus, melanoma, Hodgkin's lymphoma, prostate, and urinary cancers. We also defined, estimated, and illustrated indices for other cancer diagnoses from the vantage point of breast cancer in pre, during, and post-COVID-19 eras. The angle vectors post the COVID-19 were 72% less than pre-pandemic and 28% less than during the pandemic. The movement of cancer vectors was dynamic between these eras, and movement greatly differed by type of cancer. A trend chart of cervical cancer showed statistical anomalies in the years 2019 and 2021. Based on our findings, a few future research directions are pointed out.

Patient Co-Creation Initiatives in the Ambulatory Care Setting during COVID-19: A Systematic Review.

Background and Objectives: The COVID-19 pandemic has led to significant changes in ambulatory care to meet new healthcare demands. Materials and Methods: A review of 21 articles focusing on patient co-creation initiatives during the pandemic shows that integrating patient feedback was crucial in transforming care delivery. Results: Joint efforts between healthcare professionals and patients led to new patient-focused telemedicine platforms, more efficient appointment systems, and improved safety measures. These adaptations overcame care barriers and maintained continuity of care. Key themes identified include monitoring community health standards, combining technology with patient-provider communication, and enhancing patient participation in health research. Conclusions: These co-creation efforts not only boosted patient satisfaction and outcomes but also demonstrated the potential for long-term healthcare innovations beyond the pandemic. The review further illuminates that co-creation in healthcare, particularly in tracking community health trends, is a practical strategy that involves diverse stakeholders in shaping healthcare delivery. The widespread adoption of co-creation in outpatient care during the pandemic highlights its role in driving patient-centered behavioral changes through innovative methods like crowdsourcing and dialogue conferencing. The review also recognizes that co-creation has been instrumental in responding to demographic changes, enhancing resources, creativity, and problem-solving in municipal-volunteer collaborations. Additionally, the evolution of technology in patient-provider communication, from initial resistance in the 1990s to its current critical role, particularly during the COVID-19 pandemic, underscores its importance in enhancing healthcare service delivery and patient data communication. The review also emphasizes the need for ethically and accessibly designed technology, especially for vulnerable groups, and highlights the significance of patient involvement in healthcare research, advocating for user-centered design and shared decision-making to create truly patient-centric interventions.

The Health Status of the US Veterans: A Longitudinal Analysis of Surveillance Data Prior to and during the COVID-19 Pandemic.

Chronic diseases affect a disproportionate number of United States (US) veterans, causing significant long-term health issues and affecting entitlement spending. This longitudinal study examined the health status of US veterans as compared to non-veterans pre- and post-COVID-19, utilizing the annual Center for Disease Control and Prevention (CDC) behavioral risk factor surveillance system (BRFSS) survey data. Age-adjusted descriptive point estimates were generated independently for 2003 through 2021, while complex weighted panel data were generated from 2011 and onward. General linear modeling revealed that the average US veteran reports a higher prevalence of disease conditions except for mental health disorders when compared to a non-veteran. These findings were consistent with both pre- and post-COVID-19; however, both groups reported a higher prevalence of mental health issues during the pandemic years. The findings suggest that there have been no improvements in reducing veteran comorbidities to non-veteran levels and that COVID-19 adversely affected the mental health of both populations.

Leveraging mHealth for the Treatment and Management of PLHIV.

Objective: The objective of this systematic review was to analyze published literature from the last five years to assess facilitators and barriers to the adoption of mHealth as interventions to treat and manage HIV for PLHIV (people living with HIV). The primary outcomes were physical and mental conditions. The secondary outcomes were behavior based (substance use, care engagement, and healthy habits). Methods: Four databases (PubMed, CINAHL, Web of Science, and ScienceDirect) were queried on 9/2/2022 for peer-reviewed studies on the treatment and management of PLHIV with mHealth as the intervention. The review was conducted in accordance with the Kruse Protocol and reported in accordance with PRISMA 2020. Results: Five mHealth interventions were identified across 32 studies that resulted in improvements in physical health, mental health, care engagement, and behavior change. mHealth interventions offer both convenience and privacy, meet a digital preference, increase health knowledge, decrease healthcare utilization, and increase quality of life. Barriers are cost of technology and incentives, training of staff, security concerns, digital literacy gap, distribution of technology, technical issues, usability, and visual cues are not available over the phone. Conclusion: mHealth offers interventions to improve physical health, mental health, care engagement, and behavior for PLHIV. There are many advantages to this intervention and very few barriers to its adoption. The barriers are strong, however, and should be addressed through policy. Further research should focus on specific apps for younger versus older PLHIV, based on preferences and the digital literacy gap.

Leveraging Telehealth for the Management of Breast Cancer: A Systematic Review.

BACKGROUND: Breast cancer affects 2.3 million women and kills 685,000 globally, making it the most prevalent cancer. The telemedicine modality has been used to treat the symptoms associated with breast cancer recovery. OBJECTIVES: To analyze the effectiveness of telemedicine to help women recover from the treatment-associated effects and promote overall recovery from breast cancer. METHODS: Four databases were queried for published literature from the last 10 years. The systematic literature review was conducted in accordance with the Kruse Protocol and reported in accordance with PRISMA 2020. RESULTS: Five interventions were identified in the literature, with the most dominant being eHealth and mHealth. The other interventions were telephone, video teleconference, and a combination of eHealth and mHealth. There were positive effects of these telemedicine interventions in 88% of the studies analyzed. Telemedicine is shown to positively affect physical and mental health, sleep outcomes, quality of life, and body image. The largest barriers to the adoption of telemedicine interventions are training, cost, workflow, time of providers, and low reimbursement. CONCLUSION: Telemedicine offers promise to both providers and breast cancer survivors to improve the physical and mental health detriments of both cancer and its associated treatments. It also helps women develop healthy habits to reduce the risk of reoccurrence.

Geospatial analysis as a tool to identify target areas for Chagas disease education for healthcare providers.

Chagas Disease (CD) is a neglected zoonotic disease of the Americas. It can be fatal if not diagnosed and treated in its early stages. Using geospatial and sensitivity analysis, this study focuses on understanding how to better allocate resources and educational information to areas in the United States, specifically Texas, that have the potential for increased risk of CD cases and the associated costs of addressing the disease. ICD-9 and 10 inpatient hospital diagnostic codes were used to illustrate the salience of potentially missed CD diagnoses (e.g., cardiomyopathic diagnoses) and where these are occurring with more frequency. Coding software along with GIS and Microsoft Excel 3D mapping were used to generate maps to illustrate where there may be a need for increased statewide surveillance and screening of populations at greater risk for CD. The CD cases reported to the Texas Department of State Healthcare Services (TxDSHS) are not homogenously dispersed throughout the state but rather, reveal that the incidences are in clusters and primarily in urban areas, where there is increased access to physician care, CD research and diagnostic capabilities.

HIV PrEP implementation: A multi-level systems approach.

PURPOSE: CO-PrIDE was a three-year Pre-Exposure Prophylaxis (PrEP) demonstration project to increase access to PrEP for men who have sex with men and transgender people in the Denver/Aurora Metropolitan Statistical Area. CO-PrIDE implemented a multi-level framework featuring collaboration between health systems and community organizations to link clients to PrEP prescribers and provide support services intended to help clients overcome socioeconomic barriers to PrEP uptake. These services included payment assistance, insurance navigation, and healthcare navigation. CO-PrIDE implemented a participatory mixed-methods evaluation to understand the services associated with PrEP uptake. RESULTS: From January 2016 to December 2018, navigators screened 10,129 clients for PrEP and offered supportive services. The results indicated that clients who received payment assistance were more likely to accept a PrEP prescription (aPR = 3.52, p < .0001). Additionally, clients were more likely to receive a PrEP prescription through a co-located health system model, meaning the clinical provider is located with the PrEP Navigator (aPR = 3.78, p < .001). CONCLUSIONS: The primary factors associated with increased PrEP uptake included co-location of navigation and clinical PrEP services and providing navigation to payment assistance programs. The evaluation results suggest that a multi-level framework that includes diverse support services is needed to implement a sustainable PrEP program.

Exploring Health Outcomes for U.S. Veterans Compared to Non-Veterans from 2003 to 2019.

The physical demands on U.S. service members have increased significantly over the past several decades as the number of military operations requiring overseas deployment have expanded in frequency, duration, and intensity. These elevated demands from military operations placed upon a small subset of the population may be resulting in a group of individuals more at-risk for a variety of debilitating health conditions. To better understand how the U.S Veterans health outcomes compared to non-Veterans, this study utilized the U.S. Centers for Disease Control and Prevention (CDC) Behavioral Risk Factor Surveillance System (BRFSS) dataset to examine 10 different self-reported morbidities. Yearly age-adjusted, population estimates from 2003 to 2019 were used for Veteran vs. non-Veteran. Complex weights were used to evaluate the panel series for each morbidity overweight/obesity, heart disease, stroke, skin cancer, cancer, COPD, arthritis, mental health, kidney disease, and diabetes. General linear models (GLM's) were created using 2019 data only to investigate any possible explanatory variables associated with these morbidities. The time series analysis showed that Veterans have disproportionately higher self-reported rates of each morbidity with the exception of mental health issues and heart disease. The GLM showed that when taking into account all the variables, Veterans disproportionately self-reported a higher amount of every morbidity with the exception of mental health. These data present an overall poor state of the health of the average U.S. Veteran. Our study findings suggest that when taken as a whole, these morbidities among Veterans could prompt the U.S. Department of Veteran Affairs (VA) to help develop more effective health interventions aimed at improving the overall health of the Veterans.

Assessing the effectiveness of Chagas disease education for healthcare providers in the United States.

BACKGROUND: Chagas disease is a zoonotic infection caused by the parasite Trypanosoma cruzi, which affects an estimated 8-11 million people globally. Chagas disease is almost always associated with poverty in rural areas and disproportionately impacts immigrants from Latin America living in the United States. Approximately 20-30% of people who are infected with Chagas disease will develop a chronic form of the infection that can be fatal if left untreated. Chagas disease is vastly underestimated in the United States, often goes undiagnosed and is not well understood by most U.S. healthcare providers. One of the most important ways at reducing barriers to improving diagnostics of Chagas disease in the U.S. is giving healthcare providers the most up-to-date information and access to leading experts. METHODS: An online webinar was conducted for healthcare providers, veterinarians and public health professionals using Chagas disease expert panelists. Pre and post tests were administered to participants (n = 57) to determine the efficacy in raising awareness and to determine key focus areas for improving knowledge. A Wilcoxon rank-sum was used for non-parametric variables equivalent and for questions that assessed knowledge the McNemar's Chi-Square test was used. RESULTS: There were statistically significant learning increases in multiple categories including transmission (p = <.001), clinical presentation (p = 0.016), diagnostics (p = <.001), and treatment (p = <.001). CONCLUSION: Providing easily accessible learning opportunities using validated testing and evaluations should be further developed for rural healthcare providers in the U.S. as well as healthcare providers serving under represented populations such as immigrants. There is a clear lack of knowledge and awareness surrounding Chagas disease in the United States and just by raising awareness and providing education on the topic, lives will be saved.

Obesity and Morbidity Risk in the U.S. Veteran.

The obesity epidemic in the United States has been well documented and serves as the basis for a number of health interventions across the nation. However, those who have served in the U.S. military (Veteran population) suffer from obesity in higher numbers and have an overall disproportionate poorer health status when compared to the health of the older non-Veteran population in the U.S. which may further compound their overall health risk. This study examined both the commonalities and the differences in obesity rates and the associated co-morbidities among the U.S. Veteran population, utilizing data from the 2018 Behavioral Risk Factor Surveillance System (BRFSS). These data are considered by the Centers for Disease Control and Prevention (CDC) to be the nation's best source for health-related survey data, and the 2018 version includes 437,467 observations. Study findings show not only a significantly higher risk of obesity in the U.S. Veteran population, but also a significantly higher level (higher odds ratio) of the associated co-morbidities when compared to non-Veterans, including coronary heart disease (CHD) or angina (odds ratio (OR) = 2.63); stroke (OR = 1.86); skin cancer (OR = 2.18); other cancers (OR = 1.73); chronic obstructive pulmonary disease (COPD) (OR = 1.52), emphysema, or chronic bronchitis; arthritis (OR = 1.52), rheumatoid arthritis, gout, lupus, or fibromyalgia; depressive disorders (OR = 0.84), and diabetes (OR = 1.61) at the 0.95 confidence interval level.

Causes of Death in Military Working Dogs During Operation Iraqi Freedom and Operation Enduring Freedom, 2001-2013.

BACKGROUND: Military working dogs (MWDs) are a major asset in the theater of operations. Their unique abilities make them ideal for tasks such as tracking, patrol, and scent detection. MWDs deployed to a war zone are exposed to harsh environments and battlefield dangers that increase their risk of disease, injuries, and death. Although canines have been used extensively in Operation Iraqi Freedom (OIF) and Operation Enduring Freedom (OEF), no published studies have reported detailed causes of death among MWDs deployed to these conflicts. MATERIALS AND METHODS: Potential cases were defined as U.S. military-owned MWDs that died while deployed in Iraq (OIF) or Afghanistan (OEF) from January 1, 2001 through December 31, 2013 and identified from both official sources and unofficial sources, that is, online searches. Cases included in this study were limited to MWDs with data on cause of death obtained by abstraction from official veterinary treatment records (VTRs) from the Department of Defense Military Working Dog Veterinary Service, Joint Base San Antonio-Lackland Air Force Base, San Antonio, Texas, and Special Operations Forces units. RESULTS: We identified 92 MWDs that died while deployed to OEF/OIF from 2001 through 2013 and had cause of death information from official VTRs. For both OEF and OIF, the most common training program was Multi-Purpose Canine (36.5% and 51.7%, respectively), followed by Improvised Explosive Detector Dog for OEF (34.9%) and Patrol Explosive Detector Dog for OIF (34.5%). Injuries were the primary cause of death for 77.2% of the MWDs for which we had cause of death data. The most frequent external injuries were gunshot wounds (GSW) (31.5%), explosion or blast (26.1%), and heat stress (9.8%). The proportion of deaths due to GSW was similar for OEF and OIF (30.2% vs. and 34.5%, respectively). However, a greater proportion of MWDs died from explosions during OEF than during OIF (30.2% vs. 17.2%, respectively). Diseases were the cause of death in 23.0% of the MWDs. The most common diseases were gastric dilation and volvulus (GDV, n = 3), pleuritis (n = 2), and sepsis (n = 3). Two deaths were associated with anesthesia-related medical procedures. A total of 8.7% of cases were missing cause of death, 8.7% were missing age, 32.6% of cases were missing data on necropsy, and 14.1% were missing data on final disposition of the body. Other variables of interest including number of deployments and duration of training had a very high proportion of missing values and thus could not be analyzed. CONCLUSIONS: Our study is the most comprehensive to date that reports causes of death of MWDs deployed to OIF and OEF. However, limitations in the available data lessen the potential of our results to inform improvements in training and point of injury medical care. Better documentation in VTRs and systematic data collection into an official MWD trauma registry could lead to improved training and facilitate further development and evaluation of guidelines to improve care of wounded MWDs in future conflicts.

Brain radiation-related black dots on susceptibility-weighted imaging.

Small blood vessel injury is a feature of post irradiation brain. Susceptibility weighted imaging (SWI) is a technique that exploits the magnetic properties of tissues, such as blood and iron content and is thus sensitive to hemorrhage as a marker of small vessel injury. Our purpose was to assess post irradiation brain findings using SWI. We evaluated 12 patients with follow-up MRI studies who underwent cranial irradiation for primary or metastatic tumors. From their clinical records, the latency interval, type of radiation, and total dose were established. The number and the distribution of "black dots" on SWI were analyzed. We also compared the findings on SWI with those seen on other MRI sequences. In all patients, black dots were clearly identified on SWI, while on conventional MRI (T2 and FLAIR) none were visible. Two patients with glial tumors received radiation with fields conforming to tumor beds, while all other patients received whole brain irradiation or craniospinal radiation. The total radiation doses ranged from 45-54 Gy. Latency interval between the time of irradiation and time of detection of the black dots was four to 60 months (mean, 31 months). In ten patients diffuse black dots were observed and in two patients these were located in the irradiated field. Black dots occurred in the cerebrum, cerebellum, and choroid plexuses. None of these dots showed enhancement. Follow-up in four patients showed that the numbers of these black dots had increased. Black dots were not present before radiation in any patient. Radiation-related black dots are an effect of cranial irradiation and may be related to small vessel damage. SWI is a sensitive technique for evaluation of these black dots.

Two common bean genotypes with contrasting response to phosphorus deficiency show variations in the microRNA 399-mediated PvPHO2 regulation within the PvPHR1 signaling pathway.

Crop production of the important legume, the common bean (Phaseolus vulgaris), is often limited by low phosphorus (P) in the soil. The genotypes, BAT477 and DOR364, of the common bean have contrasting responses to P starvation. Plants from the BAT477 P deficiency tolerant genotype showed higher phosphate content and root biomass as compared to the DOR364 plants under P starvation. The PvPHR1 transcription factor-signaling pathway plays an essential role in the response to P starvation. PvPHO2, a negative regulator of this pathway, encodes an ubiquitin E2 conjugase that promotes degradation of P-responsive proteins and is the target gene of PvmiR399. PvPHO2 is downregulated in BAT477 plants under P deficiency, while such a response is not observed in P-starved DOR364 plants. Five putative PvmiR399 binding sites were identified in the 5' UTR region in both genotypes. While four sites showed an identical DNA sequence, the fifth (binding site of PvPHO2 one) showed three base changes and higher complementarity scores in DOR364 as compared to BAT477. Modified 5'RACE experiments indicated that PvmiR399 binding and/or processing was affected in DOR364 P-starved plants. We propose that a less efficient cleavage of the PvPHO2 mRNA directed by PvmiR399 would result in a higher PvPHO2-mediated degradation of P-responsive proteins in the DOR364 genotype with decreased P deficiency tolerance.

Neuronal mitochondrial amelioration by feeding acetyl-L-carnitine and lipoic acid to aged rats.

Brain function declines with age and is associated with diminishing mitochondrial integrity. The neuronal mitochondrial ultrastructural changes of young (4 months) and old (21 months) F344 rats supplemented with two mitochondrial metabolites, acetyl-L-carnitine (ALCAR, 0.2%[wt/vol] in the drinking water) and R-alpha-lipoic acid (LA, 0.1%[wt/wt] in the chow), were analysed using qualitative and quantitative electron microscopy techniques. Two independent morphologists blinded to sample identity examined and scored all electron micrographs. Mitochondria were examined in each micrograph, and each structure was scored according to the degree of injury. Controls displayed an age-associated significant decrease in the number of intact mitochondria (P = 0.026) as well as an increase in mitochondria with broken cristae (P < 0.001) in the hippocampus as demonstrated by electron microscopic observations. Neuronal mitochondrial damage was associated with damage in vessel wall cells, especially vascular endothelial cells. Dietary supplementation of young and aged animals increased the proliferation of intact mitochondria and reduced the density of mitochondria associated with vacuoles and lipofuscin. Feeding old rats ALCAR and LA significantly reduced the number of severely damaged mitochondria (P = 0.02) and increased the number of intact mitochondria (P < 0.001) in the hippocampus. These results suggest that feeding ALCAR with LA may ameliorate age-associated mitochondrial ultrastructural decay and are consistent with previous studies showing improved brain function.

Oxidative stress-induced mitochondrial failure and vasoactive substances as key initiators of pathology favor the reclassification of Alzheimer Disease as a vasocognopathy: [revisión] / Falla mitocondrial oxidativa por estres y sustancias vasoactivas como los indicadores dominantes de la patología favorecen la reclasificación de la enfermedad de Alzheimer como una vasocognopatia: [review]

La enfermedad de Alzheimer y el accidente cerebrovascular son dos causas que conducen a la demencia relativa a la edad. El aumento de la evidencia apoya la idea de que la hipoperfusión crónica es sobre todo responsable de la patogénesis que es la base de ambos procesos de la enfermedad. La hipoperfusión se asocia al desequilibrio oxidativo, en gran parte debido a las especies reactivas del oxígeno, que se asocian a otros desórdenes degenerativos relativos a la edad. Evidencia reciente indica que un estímulo crónico de lesión induce la hipoperfusión vista en la microcirculación de las regiones vulnerables del cerebro. Esto conduce a la falta de energía, manifestada por daño a la ultraestructura mitocondrial. Los trastornos mitocondriales conducen a la formación de una gran cantidad de mitocondrias “hipoxicas” electrón-densas y causan la sobreproducción de deleciones en el ADN mitocondrial (mtADN), debidas muy probablemente a la ruptura de la doble hélice. Además, estas anormalidades mitocondriales coexisten con la actividad redox incrementada, peroxidación lipídica y la oxidación del ARN, que son características bien establecidas de la patología de Alzheimer, antes de la aparición de los depósitos del b-amiloide. En la enfermedad de Alzheimer, el estrés oxidativo ocurre dentro de los varios compartimientos celulares y dentro de ciertos tipos de células más que en otros, a saber el endotelio vascular, que se asocia a daño aterosclerótico, así como en las neuronas piramidales y glia. Es interesante que estas células vulnerables demuestran deleciones del mtADN y marcadores de estrés oxidativo solamente en las regiones que están cercanamente relacionadas a los vasos dañados. Esta evidencia sugiere fuertemente que la hipoperfusión crónica induce la acumulación de los productos del estrés oxidativo. Además, las lesiones de la pared vascular del cerebro se correlacionan linealmente con el grado de daño celular neuronal y glial. Por lo tanto, concluimos que la hipoperfusión crónica es un iniciador clave del estrés oxidativo en varias células parénquimales del cerebro, y las mitocondrias parecen ser blancos primarios para el daño de cerebro en la enfermedad de Alzheimer. En este trabajo, delineamos el papel de la acumulación continua de los productos del estrés oxidativo, tales como una abundancia de productos de óxido nítrico (vía la sobreexpresión de NO sintasa inducible y/o neuronal (iNOS y nNOS respectivamente) y de acumulación del peroxinitrito, como factores secundarios pero acelerantes que comprometen la barrera hematoencefálica. Si éste resulta ser el caso, las intervenciones farmacológicas que apuntan a la hipoperfusion crónica pudieran mejorar las características dominantes de la demencia neurodegenerativa.

Kernicterus by glucose-6-phosphate dehydrogenase deficiency: a case report and review of the literature.

INTRODUCTION: Glucose-6-phosphate dehydrogenase deficiency is an X-linked recessive disease that causes acute or chronic hemolytic anemia and potentially leads to severe jaundice in response to oxidative agents. This deficiency is the most common human innate error of metabolism, affecting more than 400 million people worldwide. CASE PRESENTATION: Here, we present the first documented case of kernicterus in Panama, in a glucose-6-phosphate dehydrogenase-deficient newborn clothed in naphthalene-impregnated garments, resulting in reduced psychomotor development, neurosensory hypoacousia, absence of speech and poor reflex of the pupil to light. CONCLUSION: Mutational analysis revealed the glucose-6-phosphate dehydrogenase Mediterranean polymorphic variant, which explained the development of kernicterus after exposition of naphthalene. As the use of naphthalene in stored clothes is a common practice, glucose-6-phosphate dehydrogenase testing in neonatal screening could prevent severe clinical consequences.
