Death Rate Research Articles

Prone positioning in awake patients without ventilatory support does not alter major clinical outcomes in severe COVID-19: results from a retrospective observational cohort study, systematic review and meta-analysis.

During the Coronavirus disease (COVID-19) pandemic, clinicians recommended awake-prone positioning (APP) to avoid the worst outcomes. The objectives of this study were to investigate if APP reduces intubation, death rates and hospital length of stay (HLOS) in acute COVID-19. We performed a retrospective cohort with non-mechanically ventilated patients hospitalized in a reference center in Manaus, Brazil, 2020. Participants were stratified into APP and awake-not-prone positioning (ANPP) groups. Also, we conducted a systematic review and performed a meta-analysis to understand if this intervention had different outcomes in resource-limited settings (PROSPERO CRD42023422452). A total of 115 participants were allocated into the groups. There was no statistical difference between both groups regarding time to intubation (HR: 0.861; 95 CI: 0.474-1.1562; p = 0.622) and time to death (HR: 1.666; 95 CI: 0.939-2.951; p = 0.081). APP was not significantly associated with reduced HLOS. A total of 86 articles were included in the systematic review, of which 76 (88,3%) show similar findings after APP. Also, low/middle, and high-income countries were similar regarding such outcomes. APP in COVID-19 does not present clinical improvement that affects mortality, intubation rate and HLOS. The lack of a prone position protocol, obtained through a controlled study is necessary. After 3 years, APP benefits are still inconclusive.

[Chinese expert consensus on treatment of osteoporotic fractures with teriparatide (2024 edition)].

Osteoporotic fracture is the most serious complication of osteoporosis, which is a special type of pathologic fracture of the skeleton that occurs because of osteoporosis. It is characterized by delayed fracture healing, high risk of re-fracture, high rate of disability and death, difficulty in treatment and long treatment time, and re-fracture has a"cascade effect". Guidelines in different countries recommend that patients with osteoporotic fractures and those at very high risk of fracture should consider anabolic agents as first treatment choice. Teriparatide is the only anabolic agent approved by National Medical Products Administration (NMPA), and it has the clinical efficacy of improving fracture healing, reducing the risk of re-fracture, and improving bone microstructure in the treatment of osteoporotic fracture. Due to deficiencies in the current standardization of clinical use of teriparatide, Committee of Accelerated Rehabilitation After Osteoporotic Fractures of China Association of Rehabilitation Technology Transformation and Promotion, Bone and Joint Group of Chinese Society of Osteoporosis and Bone Mineral Research and Osteoporosis Working Committee of Chinese Association of Orthopedic Surgeons developed this consensus. The development of this consensus follows the modified Delphi method and forms 8 evidence-based medical recommendations, aiming to propose methods and precautions for standardizing the application of teriparatide, and to emphasize the importance of teriparatide application for the treatment of patients with osteoporotic fracture.

Design, Rationale and Initial Findings From HERA-FIB on 10 222 Patients With Atrial Fibrillation Presenting to an Emergency Department Over An 11-Year Period.

For the majority of patients with atrial fibrillation (AF), disease management has improved in recent years. However, there are still populations underrepresented or excluded in current registries and randomized controlled trials. HERA-FIB (Heidelberg Registry of Atrial Fibrillation) was planned to assess real-world evidence for the prevalence, demographic characteristics and management of patients with the diagnosis of AF presenting consecutively to a chest pain unit. HERA-FIB is a retrospective, observational, single-center study on patients with a diagnosis of AF presenting to a chest pain unit from June 2009 until March 2020. This article describes the structure, governance, outcome assessment, quality and data collection processes of the registry. Additionally, characteristics of populations of special interest are described. The study consecutively enrolled 10 222 patients presenting with AF to the chest pain unit of the University Hospital of Heidelberg. Clinical parameters and patient characteristics were assessed retrospectively. Outcome parameters included rates for all-cause death, stroke, myocardial infarction and major bleedings. We were able to investigate patient cohorts of special interest such as advanced chronic kidney disease, octogenarians, and those with acute coronary syndrome who are often underrepresented in current studies and randomized controlled trials. HERA-FIB is one of the largest real-world single-center retrospective registries on patients with AF, which captures the era of transition from vitamin K antagonists to non-vitamin K oral anticoagulation regimens in clinical practice and offers the possibility to investigate patient populations usually underrepresented or excluded in current available randomized controlled trials and registries.

How do new crises impact HIV risk behaviour – exploring HIV risk behaviour according to COVID-19-related orphanhood status in South Africa?

ABSTRACT The COVID-19 pandemic resulted in high death rates globally, and over 10.5 million children lost a parent or primary caregiver. Because HIV-related orphanhood has been associated with elevated HIV risk, we sought to examine HIV risk in children affected by COVID-19 orphanhood. Four hundred and twenty-one children and adolescents were interviewed, measuring seven HIV risk behaviours: condom use, age-disparate sex, transactional sex, multiple partners, sex associated with drugs/alcohol, mental health and social risks. Approximately 50% (211/421) experienced orphanhood due to COVID-19, 4.8% (20/421) reported living in an HIV-affected household, and 48.2% (203/421) did not know the HIV status of their household. The mean age of the sample was 12.7 years (SD:2.30), of whom 1.2% (5/421) were living with HIV. Eighty percent (337/421) reported at least one HIV risk behaviour. HIV sexual risk behaviours were more common among children living in HIV-affected households compared to those not living in HIV-affected households and those with unknown household status (35.0% vs. 13.6% vs.10.8%, X2 = 9.25, p = 0.01). Children living in HIV-affected households had poorer mental health and elevated substance use (70.0% vs. 48.5%, X2 = 6.21, p = 0.05; 35.0% vs. 19.9%, X2 = 4.02, p = 0.1306, respectively). HIV-affected households may require specific interventions to support the health and well-being of children and adolescents.

TRPV4 modulation participates in paraoxon-induced brain injury via NMDA and NLRP3 regulation.

Organophosphorus pesticide poisoning can lead to severe brain damage, but the specific mechanisms involved are not fully understood. Our research aims to elucidate the function of the TRPV4 ion channel in the development of brain injury induced by paraoxon (POX). In vivo, we examined the survival rate, behavioral seizures, histopathological alterations, NMDA receptor phosphorylation, as well as the expression of the NLRP3-ASC-caspase-1 complex and downstream inflammatory factors in the POX poisoning model following intervention with the TRPV4 antagonist GSK2193874. In vitro, we investigated the effects of GSK2193874 on NMDA-induced inward current, cell viability, cell death rate, and Ca2+ accumulation in primary hippocampal neurons. The treatment with the TRPV4 antagonist increased the survival rate, suppressed the status epilepticus, improved pathological damage, and reduced the phosphorylation level of NMDA receptors after POX exposure. Additionally, it inhibited the upregulation of NLRP3 inflammasome and inflammatory cytokines expression after POX exposure. Moreover, the TRPV4 antagonist corrected the NMDA-induced increase in inward current and cell death rate, decrease in cell viability, and Ca2+ accumulation. TRPV4 participates in the mechanisms of brain injury induced by POX exposure through NMDA-mediated excitotoxicity and NLRP3-mediated inflammatory response.

Global, regional, and national burden of atrial fibrillation/flutter related to metabolic risks over three decades: estimates from the global burden of disease study 2019.

Atrial fibrillation/atrial flutter (AF/AFL) remains a significant public health concern on a global scale, with metabolic risks playing an increasingly prominent role. This study aimed to investigate comprehensive epidemiological data and trends concerning the metabolic risks related-AF/AFL burden based on the data from the Global Burden of Disease (GBD) study 2019. The analysis of disease burden focused on numbers, age-standardized rates (ASR) of deaths, disability-adjusted life years (DALYs), and estimated annual percentage change (EAPC), while considering factors of age, sex, sociodemographic index (SDI), and locations. In 2019, there was a culmination of 137179 deaths and 4099146 DALYs caused by metabolic risks related-AF/AFL worldwide, with an increase of 162.95% and 120.30% respectively from 1990. High and high-middle SDI regions predominantly carried the burden of AF/AFL associated with metabolic risks, while a shift towards lower SDI regions had been occurring. Montenegro had the highest recorded death rate (7.6 per 100000) and DALYs rate (146.3 per 100000). An asymmetrically inverted V-shaped correlation was found between SDI and deaths/DALYs rates. Moreover, females and the elderly exhibited higher AF/AFL burdens, and young adults (over 40 years old) also experienced an annual increase. The global AF/AFL burden related to metabolic risks has significantly increased over past three decades, with considerable spatiotemporal, gender-based, and age-related heterogeneity. These findings shed valuable light on the trends in the burden of metabolic risks related-AF/AFL, and offered insights into corresponding strategies.

The Impact of COVID-19 on Mortality and Clinical Characteristics in Hospitalized Patients With Peripheral Artery Disease in the Year 2020 in Germany.

The COVID-19 pandemic developed its full destructive capacity in 2020. This retrospective study aimed to examine the effects of COVID-19 on the mortality and the clinical characteristics in PAD patients with COVID-19 compared to PAD patients without COVID-19. Data derived from a German nationwide register of the year 2020 which encompassed all hospitalized patients with PAD (n = 173.075); N = 2553 also suffered from a COVID-19 infection and had significantly higher mortality rates of 11.2%. PAD + COVID-19 patients presented more clinical complications like major amputations (11.59%), myocardial infarction (2.08%), cardiogenic shock (2.98%), chronic kidney failure with GFR<= 15mL/min (5.33%) and prolonged ventilation time >48 h (3.37%). Rates of pulmonary thromboembolism (0.24%), myocardial infarction (2.08%), and stroke (1.02%) were low in patients with PAD + COVID-19. Adjusted regression analyses for risk differences revealed possible causes of higher mortality rates, such as prolonged ventilation time, pneumonia, major amputations, multiple organ system failure, and length of hospital stay in patients with severe PAD (Rutherford 5-6) + COVID-19. Pneumonia and major amputations were associated with high mortality rates in PAD + COVID-19 in 2020. However, we could not detect a relevant influence of pulmonary thromboembolism, myocardial infarction or stroke on higher death rates of PAD + COVID-19.

Long-Term Comparative Efficacy and Safety of Risdiplam and Nusinersen in Children with Type1 Spinal Muscular Atrophy.

Spinal muscular atrophy (SMA) is a severe genetic neuromuscular disease characterized by a loss of motor neurons and progressive muscle weakness. Children with untreated type1 SMA never sit independently and require increasing levels of ventilatory support as the disease progresses. Without intervention, and lacking ventilatory support, death typically occurs before the age of 2years. There are currently no head-to-head trials comparing available treatments in SMA. Indirect treatment comparisons are therefore needed to provide information on the relative efficacy and safety of SMA treatments for healthcare decision-making. The long-term efficacy and safety of risdiplam versus nusinersen in children with type1 SMA was evaluated using indirect treatment comparison methodology to adjust for differences between population baseline characteristics, to reduce any potential bias in the comparative analysis. An unanchored matching-adjusted indirect comparison was conducted using risdiplam data from 58 children in FIREFISH (NCT02913482) and published aggregate nusinersen data from 81 children obtained from the ENDEAR (NCT02193074) and SHINE (NCT02594124) clinical trials with at least 36months of follow-up. Children with type1 SMA treated with risdiplam had a 78% reduction in the rate of death, an 81% reduction in the rate of death or permanent ventilation, and a 57% reduction in the rate of serious adverse events compared with children treated with nusinersen. Children treated with risdiplam also had a 45% higher rate of achieving a Hammersmith Infant Neurological Examination, Module2 motor milestone response and a 186% higher rate of achieving a ≥ 4-point improvement in Children's Hospital of Philadelphia Infant Test of Neuromuscular Disorders compared with children treated with nusinersen. Long-term data supported risdiplam as a superior alternative to nusinersen in children with type1 SMA. Video abstract available for this article. Video abstract (MP4 184542 KB).

Outcomes of Pregnancies in Women with Congenital Heart Disease: A Study in a Tertiary Care Hospital in Bangladesh

Background: Pregnancies in individuals with congenital heart disease (CHD) frequently pose complex challenges. The presence of CHD elevates the risks not only for the expectant mother but also for the well-being of the developing fetus. Additionally, careful monitoring and specialized medical care are crucial throughout the pregnancy to ensure the best possible outcomes for both. Objective: This study was aimed to assess the outcomes of pregnancies in women with congenital heart disease. Methods: This was a cross-sectional observational study that was conducted in the Combined Military Hospital (CMH), Dhaka, Bangladesh from January 2020 to December 2021. A total 30 pregnant women with congenital heart disease were enrolled through purposive sampling. All the demographic and clinical information was recorded. Data were processed, analyzed, and disseminated by using MS Office tools. Results: Among participants, Lower Segment Cesarean Section (LSCS) was the most common delivery (43.3%), followed by vaginal delivery (36.7%). Instrumental delivery, specifically through outlet forceps, was found in 6.7% of cases. Pregnancy termination occurred in 6.7% due to inevitable abortion and 3.3% for medical reasons, resulting in one maternal death (3.3%). Perinatal outcomes included 90% live births and 81.5% with Apgar scores ≥9. Neonatal Intensive Care Unit (NICU) admission was required for 33.3%, with a 3.3% perinatal death rate. Conclusions: In pregnant women with congenital heart diseases, common delivery modes are Lower Segment Cesarean Section (LSCS) and vaginal delivery. Termination and maternal fatality rates are low. Perinatal outcomes are generally positive, with most births resulting in live infants with Apgar scores ≥9 and high newborn survival rates, although some require Neonatal Intensive Care Unit (NICU) admission.

Using the Lagrange Interpolation Polynomial Method to calculate the prevalence of coronavirus disease 2019 (COVID-19) in Turkey

The goal of this paper is to look into a numerical approximation for the spread of the coronavirus disease 2019 (COVID-19) in Turkey. From March 11th to November 30th, all data is examined one by one for this purpose. The Lagrange interpolation method does not require evenly spaced x values. On the other hand, it is usually preferable to look for the closest value in the table and then use the lowest-order interpolation that is consistent with the functional form of the data. Using this method, a function for monthly and general data on the number of COVID-19 disease deaths and cases infected with the disease is obtained. Matlab programming is used to obtain Lagrange interpolation polynomials. Simulations for month by month and general data are obtained using Lagrange interpolation polynomial. The rate of spread of disease and death numbers is obtained by taking the first derivative of this function. Monthly and general tables are constructed for this propagation rate data.  Peak point of the disease and different change values ​​are determined from the information in these simulations. The rates of death and spread of the disease by months are compared. As a result of this comparison, it can be seen in which months the rate of spread of disease and death increases and decreases. Monthly increase and decrease values ​​can be seen from the Figure 3-Figure 6. For example, a relative decrease can be observed in April and May

Comparisons of energy metabolism and personality traits before and after angling in crucian carp (Carassius auratus)

Catch and release has become a very popular fish conservation strategy and fisheries management tool. The physiological and behavioral changes in individuals who experience catch and release may be adaptive. These individuals may exhibit more cautious bait use or hook avoidance behavior when faced with lures again. Here, our study was conducted on crucian carp (Carassius auratus) to compare energy metabolism and personality (e.g. activity) before and after angling for three bouts of repeated angling. Our study showed that the standard metabolic rate, maximum metabolic rate, aerobic scope and factorial aerobic scope were all lower after three bouts of repeated angling, and the metabolic rates were greater before angling than after angling in the first two bouts of angling. In addition, the total magnitude of excess postexercise oxygen consumption after repeated angling also showed a decreasing trend as the number of angled bouts increased. The percentage of time spent moving increased after three bouts of repeated angling, but there were no changes in either individual swimming speed or total distance traveled. Our results suggest that repeated angling causes a high death rate and decreases the aerobic/anaerobic metabolic capacity of crucian carp, which may reduce their metabolic potential for other physiological functions, such as locomotion, growth and digestion. Future studies should continue to focus on the effects of fishing on the physiology, behavior, and population dynamics of fish.

Abstract PO2-23-12: Innovative Metastatic Breast Cancer Therapy, CBT300, Reverses Drug and Immune Resistance

Abstract For many patients with metastatic breast cancer (MBC), their disease is treatable but incurable. Although the rate of death from MBC has significantly decreased over the last 10 years due to early detection and new treatment options, MBC still accounts for over 40,000 deaths each year in the US that has been consistent for the past 30 years. Recently, it is estimated that 90% of those deaths were due to drug resistant recurrent disease. Nearly 45% of MBC deaths can be attributed to a subpopulation of patients with metastatic triple negative breast cancer (mTNBC). Despite MBC’s initial sensitivity to chemotherapy, it often recurs at greater than 40% in stage I-III patients and greater than 80% in stage IV patients which have a dismal 5-year survival of 12%. African American women have a 40% greater incidence of death from MBC despite a 4% lower risk of diagnosis. Unfortunately, current therapies do little to reduce drug resistance and death for recurrent drug resistant MBC. Currently, the only therapies approved by the FDA for recurrent TNBC patients are Keytruda plus chemotherapy and an Antibody Drug Conjugate (ADC) called Sacituzumab Govitecan. Keytruda (anti-PD-L1) is an immune checkpoint inhibitor(ICI) given with chemotherapy (nab-paclitaxel, paclitaxel, or gemcitabine plus carboplatin). The second recently approved therapy, Sacituzumab Govitecan (SG), is composed of an antibody to human trophoblast cell-surface antigen 2 (Trpo-2) coupled to SN-38 (topoisomerase I inhibitor). Although these results are very encouraging, the 80% of TNBC patients that either do not have high positive PD-L1 tumors, or don’t respond to these therapies and become drug resistant suggests that most patients with TNBC will have recurrent disease with little or no hope for survival. For contrast, our novel MBC therapy, CBT300, targets cell surface GRP78 that has been found in over 95% of MBC and in 93% of TNBC tumors. We can now show that inhibition of cell surface GRP78 can a) induce apoptosis of drug resistant TNBC cells in vitro and in vivo, b) eliminate drug resistance showing synergistic effects with chemotherapy in vitro and in vivo, c) decrease amount of chemotherapy in combination with CBT300 and d) reduce immune suppression. Recent publications show that GRP78 is found on many types of tumor cell surfaces but not on normal cell surfaces. In fact, tumor cell surface GRP78 (csGRP78) is important for many aspects of MBC development, including cell survival, proliferation, chemoresistance, angiogenesis, metastasis formation, immune suppression, and stem cell formation. Recently, it has been shown that increased cell surface GRP78 expression in TNBC patients was significantly associated with later stage, increased distant metastasis, increased aggressiveness, shorter disease-free survival, and decreased overall survival. In studies to help understand how cell surface GRP78 causes MBC progression and drug resistance, we discovered a novel GRP78 binding transmembrane protein on TNBC cells called Receptor Tyrosine Kinase Orphan Receptor-1 (ROR1). Using the GRP78 binding domain from ROR1 and a human Fc IgG1 domain, we created a biologic fusion protein that is a potent and cell surface specific GRP78 inhibitor, CBT300. We now show that CBT300’s elimination of cell surface GRP78 destabilizes and removes oncofetal proteins ROR1, Cripto-1, and checkpoint protein PD-L1 from tumor cell surfaces resulting in reversal of chemoresistance, reduction in immune suppression, inhibition of stem cell phenotype and increased tumor cell apoptosis. Since ROR1, Cripto-1 and PD-L1 are three of the major redundant pathways for tumor drug resistance, immune suppression and stem cell formation, the ability to inhibit all these pathways with CBT300, a single safe and very efficacious therapy, is very innovative and could be a significant advance for the treatment of MBC.

Mortality from the 1944–1945 famine in Java, Indonesia

AbstractThis article examines the human toll of the 1944–1945 famine in Java, Indonesia's main island. It estimates birth and death rates for the Indonesian population in Java during 1941–1951. Using the net population loss method, the article approximates a net loss of 3.3 million people during the 1942–1945 Japanese occupation period. This includes 1.8 million excess deaths; 0.7 million during 1944 and 1.1 million during 1945. The remainder are 1.4 million missing births in 1944 and 1945, associated with the malnutrition of women of childbearing ages and physical separation of wives from husbands recruited by Japanese authorities for forced labour.

The burden of alcohol-related cardiovascular complications in young and middle-aged adults: rising burden of atrial fibrillation and hypertensive heart disease

Background and Aims The burden of alcohol-related complications is high and rising. However, there are notable deficiencies in comprehensive epidemiological study focusing on cardiovascular complications from alcohol, especially among young and middle-aged adults. We thus aimed to determine the burden of these conditions in young and middle-aged adults globally. Methods and Results We used data from the Global Burden of Disease Study 2019 and analysed the mortality and disability-adjusted life years of alcohol-associated cardiovascular complications in young and middle-aged adults. The findings were classified by sex, region, country, and Sociodemographic Index (SDI). The highest age-standardized death rates (ASDR) were observed in stroke 0.84 (95% UI 0.60–1.09), followed by alcoholic cardiomyopathy 0.57 (95% UI 0.47–0.66) per 100,000 population. The overall burden of alcohol-associated cardiovascular complications decreased globally but increased in atrial fibrillation and hypertensive heart disease. Regionally, most regions underwent a decrease in ASDR, but an increase was observed in Southeast Asia (+2.82%), Western Pacific (+1.48%), low-middle (+1.81%), and middle SDI (+0.75%) countries. Nevertheless, the ASDR and ASDALYs were highest in Europe. Conclusions The impact of alcohol-associated atrial fibrillation and hypertensive heart disease has increased over the last decades. Regarding region, the burden in Europe and the rising burden in Asia, require immediate public health policy to lessen these cardiovascular complications from alcohol in young and middle-aged adults.

Abstract PO5-09-09: Incidence of Breast Cancer in Hispanic Women Across the US: A Focus on Texas

Abstract Introduction Breast cancer (BC) is one of the most common cancers affecting the female population in the United States, particularly among the Hispanic community. According to the CDC, the incidence rate of new breast cancer cases in Hispanic women is 95.6 per 100,000 annually, and the mortality rate is 13.7 per 100,000 women annually. Texas is home to one of the largest Hispanic communities in the US. By analyzing the prevalence, mortality, and access to healthcare services in Texas, we can shed light on the unique aspects of breast cancer within the Hispanic population. Overall, this study will provide valuable insights and identify potential avenues for reducing disparities and improving healthcare outcomes for Hispanic women affected by breast cancer. Materials and methods This study used comparative data from State Cancer Profiles on the CDC and NIH databases. The database was used to generate an overall comparison of breast cancer in Hispanic women across different US states. Comparison factors analyzed include incidence, mortality, insurance, and screening efforts. Significant differences were noted especially in Texas. Graphs and quantitative data for comparison factors were generated. This data is from 2015-2019 unless noted. Results The incidence of breast cancer in Hispanic women in Texas (TX) is 93.5 (Age-Adjusted Incidence Rate-cases per 100,000) with a CI of (92.2-94.8). The incidence of BC in Hispanic women in the US averages 99.0 with a CI of 98.7-99.9. From the incidence data, Hispanic women in Texas have a lower overall incidence of BC compared to the rest of the Hispanic females in the US. When analyzing the mortality rate, Hispanic women in TX have an Age-Adjusted Death Rate (deaths per 100,000) of 15.2 (CI of 14.7-15.8). In the US, Hispanic women have an Age-Adjusted Death Rate (deaths per 100,000) of 13.0 (CI of 13.4-13.9). To analyze preventative measures, a graph reporting mammogram use in 2020 by state was gathered. In TX 2020, the estimated age-adjusted prevalence of mammograms among Hispanic females from 50-74 years old was 75.0% (CI of 67.0%-81.7%). Nationally, the age-adjusted prevalence among Hispanic females 50-74 years who reported mammogram screening in 2 years was 79.7% (CI of 76.6 – 82.4). As for Texas insurance rates in 2020, Hispanic women under 65 years old, 27.4 % reported being uninsured. In comparison, other ethnicities such as African American (non-Hispanic) women, 16.5% reported to be uninsured, and white (non-Hispanic) women in Texas 11.8 % reported to be uninsured. Additionally, to further analyze if the lack of preventative measures was causing women to have a higher mortality rate, the instance of late-stage diagnosis of BC in Texan Hispanic women was analyzed. The age-adjusted incidence rate of late-stage breast cancer in Hispanic women was reported to be 33.4 (CI of 32.6-34.2) and the national incidence of late-stage BC in Hispanic women is 35.0 (CI of 35.1-35.8). Conclusion Even with Texas having one of the largest Hispanic communities, Hispanic women with breast cancer in Texas are faced with obstacles that lead to an increase in their mortality rate. As seen in the results, Hispanic women have less incidence of BC (including late stage) than their equivalent across the US but Hispanic women in TX have higher mortality rates in comparison. This is additionally accompanied by a decrease in insured women and a decrease in the utilization of cancer screenings. Lack of access to affordable healthcare and lack of regulatory cancer screenings cause Hispanic women to meet their premature death. Further analysis of the effects of affordable health care or further molecular investigation of this population is encouraged to research to fully conclude the reason behind this population's disparities.

Abstract PO1-16-11: Real-world features and outcomes of young advanced breast cancer (ABC) patients (pts) from RegistEM (GEICAM/2014-03) study

Abstract Background: BC is the most incident cancer worldwide in &amp;lt; 40 years old (y) women. Increasing body mass index and changes in reproductive history contribute to the growing incidence of premenopausal BC. A higher proportion of luminal B-like and estrogen receptor negative (ER─) tumors, an increased risk of early relapse, and more unfavorable longer-term outcomes for young women with ER+ tumors when compared to older women, have been reported. In this analysis, we focus on age-specific BC characterization from a real-world population-based perspective. Methods: Pts were enrolled in the non-interventional and ambispective RegistEM study in ABC diagnosed between 2016 and 2019. We describe the features and outcomes of &amp;lt; 50 y pts at their initial BC diagnosis according to their BC subtype. BC subtypes were based on the most recent tumor tissue sample (distant metastasis, and in its absence, primary BC). Comparisons between &amp;lt; 40 and ≥ 50 y groups were performed. Results: Pts &amp;lt; 50 y represent 39% (n=685) of total pts with available data (n=1739, any age group) in the registry. By age, 12% (n=212) were &amp;lt; 40y, and 27% (n=473) 40-49y. At first BC diagnosis, 75% and 25% pts had early BC (EBC) and de novo metastatic BC (MBC), respectively. In EBC pts, stage II (50%) and III (28%) were the most frequent at diagnosis; invasive non-special type carcinoma was the predominant morphology, and grade 2 was the most common histological grade, but grade 3 was predominant in TN pts and HER2+ &amp;lt; 40y pts. The median time to recurrence was &amp;lt; 2y in TN pts, 3y in HER2+ pts, and 6y in luminal HER2─ pts. At ABC diagnosis, the median age was 47y, all pts were female but one, 98% white, and 60% premenopausal (94% were premenopausal at EBC diagnosis). A family history of BC and/or ovarian cancer was reported in 34% pts, and a hereditary-risk genetic test was performed in 39% (254 of 652) pts; 12% (n=30) had BRCA1/2 mutations, with a proportion higher in TN pts (9 of 33, 27%) vs. luminal HER2─ (21 of 183, 12%) and HER2+ (0 of 38) pts. Visceral disease was the most frequent in all subgroups, highlighting statistical differences (p=0.022) between age groups ( &amp;lt; 40y 55% vs. ≥50y 71%) only in TN pts. 60% had ≤ 2 locations involved, similarly in all subgroups. The presence of &amp;gt;2 metastatic locations was statistically higher in HER2+ pts ≥50y (54%) vs both &amp;lt; 40y (32%) and 40-49y (48%). Brain disease was more present at ABC diagnosis in TN (9%) and HER2+ (7%) than in luminal HER2─ (3%). Median no. of treatment lines (L) was 3 (range 0-11), and median follow-up 44 mo (95% CI: 41-44). 99% pts received 1L, the distribution of treatments by BC subtype within each age subgroup was similar; median duration of 1L was 21 months (mo) in luminal HER2─, 17 mo in HER2+, and 5 mo in TN pts. 68% of pts who received 1L, reached 2L. Duration of 2L dropped dramatically: 8 mo in luminal HER2─, 6 mo in HER2+, and 2 mo in TN pts. No differences between ≥50y and the rest of pts were observed in PFS for any treatment line. 49% pts had died at the database cut-off date (05-April-23), with no differences between age groups, but TN pts had the highest death rate (80%). Additional data according to BC subtypes and age groups are in the table. Conclusions: Luminal HER2─ was the predominant BC subtype in all age subgroups. Visceral disease was more prevalent in young TN pts compared to older pts. TNBC pts experienced a shorter median time to recurrence and the highest mortality rate regardless of age, compared to HER2+ and luminal HER2- pts, indicating the need for targeted interventions in this subgroup.

Preventable Premature Deaths from the Five Leading Causes of Death in Nonmetropolitan and Metropolitan Counties, United States, 2010-2022.

A 2019 report quantified the higher percentage of potentially excess (preventable) deaths in U.S. nonmetropolitan areas compared with metropolitan areas during 2010-2017. In that report, CDC compared national, regional, and state estimates of preventable premature deaths from the five leading causes of death in nonmetropolitan and metropolitan counties during 2010-2017. This report provides estimates of preventable premature deaths for additional years (2010-2022). 2010-2022. Mortality data for U.S. residents from the National Vital Statistics System were used to calculate preventable premature deaths from the five leading causes of death among persons aged <80 years. CDC's National Center for Health Statistics urban-rural classification scheme for counties was used to categorize the deaths according to the urban-rural county classification level of the decedent's county of residence (1: large central metropolitan [most urban], 2: large fringe metropolitan, 3: medium metropolitan, 4: small metropolitan, 5: micropolitan, and 6: noncore [most rural]). Preventable premature deaths were defined as deaths among persons aged <80 years that exceeded the number expected if the death rates for each cause in all states were equivalent to those in the benchmark states (i.e., the three states with the lowest rates). Preventable premature deaths were calculated separately for the six urban-rural county categories nationally, the 10 U.S. Department of Health and Human Services public health regions, and the 50 states and the District of Columbia. During 2010-2022, the percentage of preventable premature deaths among persons aged <80 years in the United States increased for unintentional injury (e.g., unintentional poisoning including drug overdose, unintentional motor vehicle traffic crash, unintentional drowning, and unintentional fall) and stroke, decreased for cancer and chronic lower respiratory disease (CLRD), and remained stable for heart disease. The percentages of preventable premature deaths from the five leading causes of death were higher in rural counties in all years during 2010-2022. When assessed by the six urban-rural county classifications, percentages of preventable premature deaths in the most rural counties (noncore) were consistently higher than in the most urban counties (large central metropolitan and fringe metropolitan) for the five leading causes of death during the study period.During 2010-2022, preventable premature deaths from heart disease increased most in noncore (+9.5%) and micropolitan counties (+9.1%) and decreased most in large central metropolitan counties (-10.2%). Preventable premature deaths from cancer decreased in all county categories, with the largest decreases in large central metropolitan and large fringe metropolitan counties (-100.0%; benchmark achieved in both county categories in 2019). In all county categories, preventable premature deaths from unintentional injury increased, with the largest increases occurring in large central metropolitan (+147.5%) and large fringe metropolitan (+97.5%) counties. Preventable premature deaths from CLRD decreased most in large central metropolitan counties where the benchmark was achieved in 2019 and increased slightly in noncore counties (+0.8%). In all county categories, preventable premature deaths from stroke decreased from 2010 to 2013, remained constant from 2013 to 2019, and then increased in 2020 at the start of the COVID-19 pandemic. Percentages of preventable premature deaths varied across states by urban-rural county classification during 2010-2022. During 2010-2022, nonmetropolitan counties had higher percentages of preventable premature deaths from the five leading causes of death than did metropolitan counties nationwide, across public health regions, and in most states. The gap between the most rural and most urban counties for preventable premature deaths increased during 2010-2022 for four causes of death (cancer, heart disease, CLRD, and stroke) and decreased for unintentional injury. Urban and suburban counties (large central metropolitan, large fringe metropolitan, medium metropolitan, and small metropolitan) experienced increases in preventable premature deaths from unintentional injury during 2010-2022, leading to a narrower gap between the already high (approximately 69% in 2022) percentage of preventable premature deaths in noncore and micropolitan counties. Sharp increases in preventable premature deaths from unintentional injury, heart disease, and stroke were observed in 2020, whereas preventable premature deaths from CLRD and cancer continued to decline. CLRD deaths decreased during 2017-2020 but increased in 2022. An increase in the percentage of preventable premature deaths for multiple leading causes of death was observed in 2020 and was likely associated with COVID-19-related conditions that contributed to increased mortality from heart disease and stroke. Routine tracking of preventable premature deaths based on urban-rural county classification might enable public health departments to identify and monitor geographic disparities in health outcomes. These disparities might be related to different levels of access to health care, social determinants of health, and other risk factors. Identifying areas with a high prevalence of potentially preventable mortality might be informative for interventions.

The role of pre-onset hair hormone in predicting the prognosis of patients with severe pneumonia and acute COVID-19 outbreak

Numerous research works have investigated the potential impact of endocrine hormones on the severity of COVID-19-related pneumonia in individuals. However, there are few studies on the effect of pre-onset neuroendocrine hormones on the prognosis of COVID-19 patients. This study looked into the prognostic value of pre-onset hair hormone levels in COVID-19 infected individuals. This study included 27 patients with COVID-19 and collected patient information and laboratory indicators. The hormone levels in hair were determined by liquid chromatography-tandem mass spectrometry (LC-MS/MS). Within 28 days, 63% of the patients in this study passed away. With 28-day mortality as the outcome index, urea nitrogen, CURB-65 score and pneumonia severity score (PSI) of 2 groups were statistically significant (P<0.05). Among all hormone levels detected in hair, only progesterone level was substantially correlated negatively with COVID-19 patients' 28-day mortality(P<0.05). The level of progesterone in hair was substantially adversely connected with the death rate at 28 days of COVID-19 patients, according to correlation and logistic regression analysis(P<0.05). Among patients with COVID-19 pneumonia, hair progesterone levels were strongly associated with 28-day mortality, which emphasizes hair progesterone's importance as a prognostic factor.

Disaggregating Death Rates of Age-Groups Using Deep Learning Algorithms

Reliable estimates of age-specific vital rates are crucial in demographic studies, while ages are, in most cases, commonly grouped in bins of five years. Indeed, public health and national systems require single age-specific data to achieve accurate social planning. This paper introduces a deep learning approach for splitting the abridged death rates, providing a more comprehensive perspective on the indirect age-specific vital rates estimation from grouped data. Additionally, we contribute to the existing literature by introducing a multi-population (countries and genders) approach, providing reliable estimates considering the heterogeneity of longevity dynamics over age, years, and across populations. We also contribute to the state of the art in indirect estimation by introducing, for the first time, a multi-population indirect estimation leveraging subnational data. Our model accurately captures mortality dynamics by age over time and among different populations. We prove the model’s ability to estimate reliable predictions of age-specific mortality rates by also studying how the hyperparameters’ choice affects the model reliability and analyzing the age-specific relative differences between the real and the estimated mortality rates.

Prostate cancer, its implications and awareness in the South Asian population: a retrospective cross-sectional cohort analysis

Introduction: The second most frequent form of cancer in males and the main reason for cancer-related deaths worldwide is prostate cancer (PC). Despite being less common than in Western nations, PC incidence and death rates have been rising throughout South Asia. This study intends to evaluate how well-informed and knowledgeable the South Asian public is about PC, its symptoms, and screening procedures among men and women. Methods: From August to September of 2022, a cross-sectional survey was carried out throughout South Asia. Participants in the research had to be at least 24 years old, and it used a practical sampling approach. A self-created questionnaire with both closed- and open-ended questions was used to gather the data. SPSS was used to conduct statistical analysis, including χ 2 tests for relationships. Results: A total of 378 individuals, comprising 57.6% men and 41.8% women, were involved in the study. Only 45.0% of participants were aware of prostate specific antigen testing for early PC diagnosis, however, 81.7% of people recognized what the prostate gland was. Approximately 87% of individuals had never received a screening for PC. Compared to males, women showed a stronger understanding of PC and its screening techniques. Notably, 94.7% believed the likelihood of effective therapy was increased by early identification. Conclusion: While women demonstrated better levels of knowledge, the study’s findings show that the general population in South Asia suffers from a serious shortage of reliable knowledge concerning PC. To promote early identification, lower morbidity, and enhance treatment success, awareness-raising and educational initiatives are essential, with a focus on both sexes. This study establishes the foundation for future research and emphasizes the necessity for targeted educational programmes in the area.
