Chicory supplementation improves growth performance in juvenile ostriches potentially by attenuating enteritis.

Introduction: Enteritis and dysbiosis are the major causes of high morbidity and mortality of juvenile ostriches. Chicory (CC) has been proven to have excellent antioxidant, anti-inflammatory, and antibacterial activities. However, it's unclear whether CC could improve the survival rate of juvenile ostriches by relieving enteritis and correcting dysbiosis. Materials and methods: South African ostrich hatchlings (Struthio camelus domesticus) were fed with and without a CC-supplemented diet, and the body weight gain and mortality were compared over 4 months of age. Fresh fecal samples of clinically healthy ostriches were collected, and 16S DNAs were analyzed. Moreover, ostrich chicks with LPS-induced enteritis were fed with different dosages (0, 20, 40, and 80 mg/kg) of chicoric acid (CA), a major bioactive component of CC, for five consecutive days. The expression levels of tight junction (TJ)-related proteins and inflammatory mediators in the ilea were detected with western blot and immunofluorescence. Results: The ostrich chicks fed on the CC-supplemented diet began to increase in weight at the 1st month of age and became remarkably heavier at the fourth month (p < 0.01) compared with those fed on the non-CC-supplemented diet. Additionally, the mortality percentage was lower in the chicks fed on the CC-supplemented diet than those fed on the non-CC-supplemented diet (19% vs. 36%, respectively). The diet with the CC supplementation significantly increased the abundance of Phascolactobacteria (linear discriminant analysis; LDA >4) and Bacteroidota (26.7% vs. 17.7%, respectively) as well as decreased the enrichment of Clostridium (5.0% vs. 9.1%, respectively) in the ostrich ilea compared to the diet without CC. The supplementation of CA at a dose of 80 mg/kg significantly increased the expression level of ZO-1 and claudin-3 (p < 0.0001) and suppressed the levels of IL-1ß, IL-6, and TNF-α (p < 0.0001) in ostriches with LPS-induced ileitis. Conclusion: Our results substantiate that CC or CA supplementation in a diet could effectively improve growth performance and reduce mortality in juvenile ostriches via modulating the gut microbiota and attenuating enteritis.

Air pollutants and primary liver cancer mortality: a cohort study in crop-burning activities and forest fires area.

Introduction: Northern Thailand experiences high levels of air pollution in the dry season due to agricultural waste burning and forest fires. Some air pollutants can enter the bloodstream, and the liver has the role of detoxifying these along with other harmful substances. In this study, we assessed the effects of long-term exposure to air pollutants on liver cancer mortality in this area. Methods: A cohort of 10,859 primary liver cancer patients diagnosed between 2003 and 2018 and followed up to the end of 2020 were included in the study. Extended time-varying covariates of the annually averaged pollutant concentrations updated each year were utilized. The associations between air pollutants and mortality risk were examined by using a Cox proportional hazard model. Results: Metastatic cancer stage had the highest adjusted hazard ratio (aHR) of 3.57 (95% confidence interval (CI):3.23-3.95). Being male (aHR = 1.10; 95% CI: 1.04-1.15), over 60 years old (aHR = 1.16; 95% CI: 1.11-1.21), having a history of smoking (aHR = 1.16; 95%CI: 1.11-1.22), and being exposed to a time-updated local concentration of PM2.5 of 40 µg/m3 (aHR = 1.10; 95% CI: 1.05-1.15) increased the mortality risk. Conclusion: We found that air pollution is one of several detrimental factors on the mortality risk of liver cancer.

Temporal Trends in Racial and Gender Disparities of Early Onset Colorectal Cancer in the United States: An Analysis of the CDC WONDER Database.

BACKGROUND: The mortality rates of early-onset colorectal cancer (EOCRC) have surged globally over the past two decades. While the underlying reasons remain largely unknown, understanding its epidemiology is crucial to address this escalating trend. This study aimed to identify disparities potentially influencing these rates, enhancing risk assessment tools, and highlighting areas necessitating further research. METHODS: Using the CDC Wide-Ranging Online Data for Epidemiologic Research (WONDER) database, this study assessed EOCRC mortality data from 2012 to 2020. Individuals under 50 years who succumbed to EOCRC were identified through the International Classification of Diseases, Tenth Revision (ICD-10) codes. Data interpretation and representation were performed using R 4.2.2 software. RESULTS: Between 2012 and 2020, EOCRC mortality rates fluctuated marginally between 1.7 and 1.8 per 100,000. Male mortality rates increased from 1.9 to 2.0 per 100,000, while female rates varied between 1.5 and 1.6 per 100,000. Significant variations were observed across age groups, with the 40-49 years category experiencing an increase from 6.34 (2012) to 6.94 (2020) per 100,000. Racial category-based data revealed the highest mortality rates among African Americans. Geographically, Mississippi and Alabama exhibited elevated mortality rates. Age-adjusted mortality rate (AAMR) assessments indicated a marked decline for both genders from 2012 to 2020, with consistently higher rates for men. CONCLUSION: The findings highlight the evolving landscape of EOCRC mortality, revealing significant gender, age, and racial disparities. These results underscore the urgent need for tailored health strategies and intensified research efforts targeting these disparities.

Changes in early HIV/AIDS mortality rates in people initiating antiretroviral treatment between 2013 and 2023: A 10-year multicenter survival study in Senegal.

BACKGROUND: HIV/AIDS-related early mortality has long been a significant challenge. Subsequent to recent policy changes and treatment advancements, we aimed to assess changes in early mortality rates in 2017-19 and 2020-23 compared to 2013-16. METHODS: This is a 10-year multicenter survival study in people living with human immunodeficiency virus having initiated ART between 2013 and 2023. We used frailty-based competing risk models to estimate adjusted early (6-month and one-year) mortality hazard ratios (HRs) in people living with HIV (PwHIV) having initiated ART in 2013-16 (comparator), 2017-19, and 2020-23. RESULTS: We enrolled 4006 persons of whom 2281 (56.9 %) were female; median age was 40 years (IQR: 31-50); 635 (15.9 %) were at WHO clinical stage IV and 934 (23.3 %) had a CD4 count <200 cells/mm3. Median follow-up was 80.4 months (IQR: 48.6-106.7). All in all, 463 participants died (4.37 deaths per 100 person-years), including 296 at one year of follow-up (7.4 % [95 % CI: 6.6-8.2]). ART initiation in 2016-19 and 2020-23 was associated with 27 % (adjusted HR [aHR]: 0.73; 95 % CI: 0.55-0.98) and 63 % (aHR: 0.37; 95 % CI: 0.25-0.56) reductions in one-year mortality rates, respectively, compared to the 2013-16 period. CONCLUSION: Early mortality risk has significantly decreased over time in Senegal. However, the proportion of PwHIV with AIDS-defining conditions remains concerning. Continued efforts to ensure early diagnosis and prompt linkage to care are needed for more impact.

Impact of different mating ratios of broiler breeder on reproductive performance during post moult phase.

Studies comparing mating ratio after forced molting are important for improving the efficiency of broiler breeder flocks. This study examined the effect of mating ratios on Egg production, chick weight, fertility, hatchability and embryonic mortality rate in Arbor Acres Plus broiler breeders post-moult phase. A total of 195 birds (62 weeks old), consisting of 15 cocks and 180 hens were randomly allocated with uniform body weight in a Completely Randomized Design into three groups based on the mating ratio (cock to hen). The groups included ratios of 1:10, 1:12, and 1:14, with each group replicated 5 times. Eggs were collected twice a day, and stored for 7 days at room temperature before placing them in the incubator. Results showed that mating ratios 1:10 and 1:12 had a positive effect on fertility rate and total hatchability compared to the 1:14 ratio. However, mating ratios did not affect laying rate, egg weight, egg mass, chick weight, hatchability of fertile eggs, and embryonic mortality rate. In conclusion, to reduce the cost of raising and caring cocks, a mating ratio of one cock to every twelve hens can be used for broiler breeders after forced molting to obtain the best fertility and hatching results.

Evaluating neonatal mortality in Malta compared with other EU countries: Exploring the influence of congenital anomalies and maternal risk factors.

BACKGROUND: Globally, 240,000 babies die in the neonatal period annually due to congenital anomalies (CA). Malta reports the highest neonatal mortality rate (NMR) among EU (European Union) Countries, constituting a public health concern. OBJECTIVES: This study describes the contribution of CA to NMR in Malta, investigating possible associations with known maternal risk factors of maternal age, nationality, and education. Additionally, it provides an update on the contribution of CA to neonatal deaths in Malta and other EU countries. METHODS: Anonymous data for births and neonatal deaths were obtained for 2006-2020 from the National Obstetrics Information System (NOIS) in Malta. Regression analyses adjusting for maternal risk factors were run on this data to explore possible associations with NMR. NMRs published by EUROSTAT 2011-2020 were used to compare mortality by underlying cause of death (CA or non-CA causes) for Malta and other EU countries. RESULTS: Between 2006 and 2020, 63,890 live births with 283 neonatal deaths were registered in Malta, (NMR 4.4 per 1000 live births). CA accounted for 39.6% of neonatal deaths. No time trends were observed in either total NMR, NMR attributed to CA or mortality due to non-CA causes. Adjusted variables revealed associations for women hailing from non-EU, low-income countries. Malta registered high NMRs compared to EU countries, most marked for deaths attributed to CA. CONCLUSIONS: Between 2006 and 2020, Malta's NMR remained stable. Maternal Nationality, from non-EU low-income countries, was associated with higher neonatal mortality. The influx of such migrants may play a partial role in the high NMRs experienced. Malta's high NMR was primarily driven by early neonatal deaths, which included high proportions of deaths due to CA and is linked to the fact that termination of pregnancy is illegal in Malta.

Predicting fish spawning phenology for adaptive management: Integrating thermal drivers and fishery constraints.

Climate warming is causing shifts in reproductive phenology, a crucial life history trait determining offspring survival and population productivity. Evaluating these impacts on exploited marine resources is essential for implementing adaptive measures from an ecosystemic approach. This study introduces a statistical model designed to predict fish spawning phenology from sea surface temperature profiles, integrating mortality-corrected hatch-date distributions inferred from fishery-dependent samplings, along with the gonadosomatic index of adult individuals. When applied to different dolphinfish (Coryphaena hippurus) populations across a broad latitudinal range, the model reasonably predicts the spawning phenology across its extensive thermal ranges, elucidating a direct relationship between mean annual temperature and the breadth of the spawning season. Despite the varying thermal profiles, results show a consistent timing of spawning peaks approximately 49 days before the peak in temperature. Importantly, these findings account for the impact of fishery constraints, such as seasonal closures or different sampling schedules, offering a robust tool for adjusting management practices in response to inter-annual temperature variations. These insights are critical for both short-term fishery management, including the strategic planning of seasonal closures, and long-term projections of spawning phenology shifts under changing thermal regimes. By enhancing our ability to predict spawning times, this research contributes significantly to the sustainable management of fish populations and the adaptive response to environmental changes.

Association of depressive symptoms with incidence and mortality rates of COVID-19 over 2 years among healthcare workers in 20 countries: multi-country serial cross-sectional study.

BACKGROUND: Long-term deterioration in the mental health of healthcare workers (HCWs) has been reported during and after the COVID-19 pandemic. Determining the impact of COVID-19 incidence and mortality rates on the mental health of HCWs is essential to prepare for potential new pandemics. This study aimed to investigate the association of COVID-19 incidence and mortality rates with depressive symptoms over 2 years among HCWs in 20 countries during and after the COVID-19 pandemic. METHODS: This was a multi-country serial cross-sectional study using data from the first and second survey waves of the COVID-19 HEalth caRe wOrkErS (HEROES) global study. The HEROES study prospectively collected data from HCWs at various health facilities. The target population included HCWs with both clinical and non-clinical roles. In most countries, healthcare centers were recruited based on convenience sampling. As an independent variable, daily COVID-19 incidence and mortality rates were calculated using confirmed cases and deaths reported by Johns Hopkins University. These rates represent the average for the 7 days preceding the participants' response date. The primary outcome was depressive symptoms, assessed by the Patient Health Questionnaire-9. A multilevel linear mixed model (LMM) was conducted to investigate the association of depressive symptoms with the average incidence and mortality rates. RESULTS: A total of 32,223 responses from the participants who responded to all measures used in this study on either the first or second survey, and on both the first and second surveys in 20 countries were included in the analysis. The mean age was 40.1 (SD = 11.1), and 23,619 responses (73.3%) were from females. The 9323 responses (28.9%) were nurses and 9119 (28.3%) were physicians. LMM showed that the incidence rate was significantly and positively associated with depressive symptoms (coefficient = 0.008, standard error 0.003, p = 0.003). The mortality rate was significantly and positively associated with depressive symptoms (coefficient = 0.049, se = 0.020, p = 0.017). CONCLUSIONS: This is the first study to show an association between COVID-19 incidence and mortality rates with depressive symptoms among HCWs during the first 2 years of the outbreak in multiple countries. This study's findings indicate that additional mental health support for HCWs was needed when the COVID-19 incidence and mortality rates increase during and after the early phase of the pandemic, and these findings may apply to future pandemics. TRIAL REGISTRATION: Clinicaltrials.gov, NCT04352634.

HEART FAILURE MORTALITY IN CHRONIC KIDNEY DISEASE: THE FATAL CROSSOVER.

BACKGROUND: Real-world mortality data regarding heart failure in patients with comorbid chronic kidney disease remains limited, especially following the advent of advanced heart failure therapies. METHODS: Using the CDC WONDER database, we included patients ≥ 25 years old who died primarily from heart failure (2011-2020) with comorbid chronic kidney disease. We calculated age-adjusted mortality rates (AAMR) per 100,000 individuals. We determined the trends over time by estimating the annual percent change (APC) using the Joinpoint regression program. RESULTS: There were 82,454 heart failure deaths with comorbid chronic kidney disease. The AAMR increased from 2.34 (95% CI, 2.28- 2.41) in 2011 to 4.79 (95% CI, 4.71- 4.88) in 2020. During the study period, Heart failure deaths among patients with comorbid chronic kidney disease increased by 149.0% compared to 59.9% in those without. Men had higher AAMR than women (3.92 [95% CI, 3.88- 3.96] vs. 2.96 [95% CI, 2.93- 2.99]). African American patients had the highest AAMR (5.85 [95% CI, 5.75- 5.96]). The Midwest region had the highest AAMR (3.83 [95% CI, 3.78- 3.89]). The AAMR was higher in the rural areas than in the urban regions (3.77 [95% CI, 3.71- 3.83] vs. 3.23 [95% CI, 3.20- 3.25]). Most patients died in hospices or nursing homes (29,000, 35.2%). CONCLUSION: Our study showed a significant increase in heart failure AAMR in patients with comorbid chronic kidney disease in recent eras. Further effort is needed to optimize cardioprotective agents for this population and to address demographic discrepancies at the policy level.

Comparing NEWS2, TRISS, and RTS in predicting mortality rate in trauma patients based on prehospital data set: a diagnostic study.

BACKGROUND: In the recent years, National Early Warning Score2 (NEWS2) is utilized to predict early on, the worsening of clinical status in patients. To this date the predictive accuracy of National Early Warning Score (NEWS2), Revised Trauma Score (RTS), and Trauma and injury severity score (TRISS) regarding the trauma patients' mortality rate have not been compared. Therefore, the objective of this study is comparing NEWS2, TRISS, and RTS in predicting mortality rate in trauma patients based on prehospital data set. METHODS: This cross-sectional retrospective diagnostic study performed on 6905 trauma patients, of which 4191 were found eligible, referred to the largest trauma center in southern Iran, Shiraz, during 2022-2023 based on their prehospital data set in order to compare the prognostic power of NEWS2, RTS, and TRISS in predicting in-hospital mortality rate. Patients are divided into deceased and survived groups. Demographic data, vital signs, and GCS were obtained from the patients and scoring systems were calculated and compared between the two groups. TRISS and ISS are calculated with in-hospital data set; others are based on prehospital data set. RESULTS: A total of 129 patients have deceased. Age, cause of injury, length of hospital stay, SBP, RR, HR, temperature, SpO2, and GCS were associated with mortality (p-value < 0.001). TRISS and RTS had the highest sensitivity and specificity respectively (77.52, CI 95% [69.3-84.4] and 93.99, CI 95% [93.2-94.7]). TRISS had the highest area under the ROC curve (0.934) followed by NEWS2 (0.879), GCS (0.815), RTS (0.812), and ISS (0.774). TRISS and NEWS were superior to RTS, GCS, and ISS (p-value < 0.0001). CONCLUSION: This novel study compares the accuracy of NEWS2, TRISS, and RTS scoring systems in predicting mortality rate based on prehospital data. The findings suggest that all the scoring systems can predict mortality, with TRISS being the most accurate of them, followed by NEWS2. Considering the time consumption and ease of use, NEWS2 seems to be accurate and quick in predicting mortality based on prehospital data set.

Pulmonary Embolism Post-Femoral Neck Fracture Surgery: A Critical Predictor of Five-Year Mortality.

Objectives: This study examines the impact of pulmonary embolism (PE) on mortality among patients with femoral neck fractures, exploring the predictive value of preoperative PE for postoperative occurrences and associated mortality over a 5-year follow-up period. Methods: We analyzed 2256 patients over 60 years old admitted with femoral neck fractures, focusing on those who developed DVT or PE postoperatively. Surgical intervention aimed within 48 hours without pharmacological thromboprophylaxis, utilizing mechanical prophylaxis instead. Postoperative management included Enoxaparin administration. Data analysis employed SPSS 21, with chi-squared tests, T-tests, and multivariate logistic regression to explore mortality and PE incidence. Results: PE was diagnosed in 1.4% of patients, with a notable mortality contrast between patients with PE (87%) and those without (59.7%) over 5 years. A history of preoperative PE emerged as a significant risk factor for postoperative PE. Despite surgical variations, no significant correlation was found between surgery type and PE incidence. Early postoperative weight-bearing and institutional rehabilitation did not significantly alter PE incidence rates. Conclusions: The study underscores the significant mortality risk associated with preoperative PE in femoral neck fracture patients. It highlights the necessity for vigilant PE risk assessment and management, challenging assumptions about the protective role of early mobility and rehabilitation in PE incidence. Further research is essential to refine patient care strategies and improve outcomes.

Fluoride Exposure from Drinking Water Increases the Risk of Stroke: An Ecological Study in Changwu Town, China.

BACKGROUND: Stroke is a major cause of death globally and the leading cause in China. Excessive fluoride exposure has been linked to cardiovascular conditions related to stroke risk factors such as hypertension, atherosclerosis, dyslipidemia, and cardiomyopathy. However, evidence supporting the association between fluoride exposure and stroke risk is limited. METHODS: We constructed an ecological study in Changwu Town, Heilongjiang Province, China, a typical endemic fluorosis area caused by excessive fluoride exposure from drinking water. We collected demographic data, stroke prevalence, and mortality information from 2017 to 2021. Fluoride exposure data were obtained from the national monitoring project on endemic fluorosis. Water fluoride concentrations were measured using the standardized methods. Trend changes in stroke rates were assessed using annual percentage change (APC). Differences in stroke rates among fluoride exposure groups were analyzed using chi-square tests. RESULTS: From 2017 to 2021, the all-ages and age-standardized stroke prevalence rates of permanent residents in Changwu Town increased year by year, while the all-ages and age-standardized mortality rates did not change significantly. The prevalence rates of stroke were significantly higher in endemic fluorosis areas compared to non-endemic areas (p < 0.001). Stratifying the population into tertile groups based on the water fluoride cumulative exposure index (WFCEI) revealed statistically significant differences in stroke prevalence rates (p < 0.001), showing a dose-response relationship with the WFCEI. However, the all-ages and age-standardized mortality rates of stroke were not found to be related to fluoride exposure. CONCLUSIONS: Long-term excessive fluoride exposure from drinking water may increase the risk of stroke prevalence, indicating fluoride overexposure as a potential risk factor for stroke.

Trends and risk factors analysis of aortic aneurysm mortality in China over thirty years: based on the global burden of disease 2019 data.

OBJECTIVES: This study aims to analyze the variation in mortality burden of aortic aneurysms (AA) and explore the associated risk factors based on Global Burden of Disease (GBD) 2019 data, investigating the mortality burden of AA in China. METHODS: Using GBD 2019 data, the mortality burden of AA in China from 1990 to 2019 was analyzed. The age-period-cohort model was utilized to analyze time trends, period, and cohort effects of 4 attributable risk factors of AA by age. RESULTS: In 2019, the total number of AA deaths in China increased by 136.1% compared to 1990, while the age-standardized mortality rate (ASMR) decreased by 6.8%. Male deaths and ASMR were higher than those of females, and ASMR increased with age. Whether viewed overall (Average Annual Percent Change (AAPC): -0.261, 95% Confidence Interval (CI): -0.383 to -0.138) or by sex (female AAPC: -0.812, 95% CI: -0.977 to -0.646; male AAPC: -0.011, 95% CI: -0.183 to 0.162), the ASMR for AA in China has shown a declining trend since 1990. Attributable risk factors such as high blood pressure, a diet high in sodium, smoking, and lead exposure increase AA mortality with age. Smoking mortality peaks between ages 80-85. The cyclical effect of high blood pressure on AA mortality significantly increases, while the cyclical effects of the other three risk factors decrease. For the population born after 1940, the cohort effect of high systolic blood pressure (SBP), a diet high in sodium, and smoking increased, while the cohort effect of lead exposure decreased. The local drift values of high SBP, a diet high in sodium, and smoking decreased, while the local drift value of lead exposure increased. High SBP was identified as the most significant attributable risk factor for AA mortality burden among both males and females, and smoking was another major attributable risk factor, particularly in males. CONCLUSION: From 1990 to 2019, fatality due to AA in China increased notably, but the ASMR showed a decreasing trend. The mortality rate of AA was influenced by age, sex, and attributable risk factors, with elderly male smokers carrying a heavy burden of death. Moreover, tobacco control and treatment of hypertension should be strengthened to reduce the burden and its impact on AA.

Global Suicide Mortality Rates (2000-2019): Clustering, Themes, and Causes Analyzed through Machine Learning and Bibliographic Data.

Suicide research is directed at understanding social, economic, and biological causes of suicide thoughts and behaviors. (1) Background: Worldwide, certain countries have high suicide mortality rates (SMRs) compared to others. Age-standardized suicide mortality rates (SMRs) published by the World Health Organization (WHO) plus numerous bibliographic records of the Web of Science (WoS) database provide resources to understand these disparities between countries and regions. (2) Methods: Hierarchical clustering was applied to age-standardized suicide mortality rates per 100,000 population from 2000-2019. Keywords of country-specific suicide-related publications collected from WoS were analyzed by network and association rule mining. Keyword embedding was carried out using a recurrent neural network. (3) Results: Countries with similar SMR trends formed naturally distinct groups of high, medium, and low suicide mortality rates. Major themes in suicide research worldwide are depression, mental disorders, youth suicide, euthanasia, hopelessness, loneliness, unemployment, and drugs. Prominent themes differentiating countries and regions include: alcohol in post-Soviet countries; HIV/AIDS in Sub-Saharan Africa, war veterans and PTSD in the Middle East, students in East Asia, and many others. (4) Conclusion: Countries naturally group into high, medium, and low SMR categories characterized by different keyword-informed themes. The compiled dataset and presented methodology enable enrichment of analytical results by bibliographic data where observed results are difficult to interpret.

COVID-19 increases mortality in hemodialysis patients: exploring links with inflammation and telomere attrition.

BACKGROUND AND OBJECTIVE: An increased risk of mortality and hospitalization was consistently demonstrated in hemodialysis (HD) patients affected by pandemic coronavirus infection (COVID-19). In this study, we analyzed parameters that may impact mortality in COVID-19 HD patients, including neutrophil-to-lymphocyte ratio (NLR), lactate dehydrogenase (LDH), C-reactive protein (CRP), COVID-19 disease status and telomere length in peripheral blood cells (TL). MATERIALS AND METHODS: A total of 130 chronic hemodialysis patients were enrolled and followed up for 18 months. Patients were categorized into groups based on their COVID-19 disease history and subsequent data about their survival status at the end of the study. Routine laboratory parameters were assessed using standard automated methods and TL was determined using the modified Cawthon method. Survival predictors were analyzed using Kaplan-Meier analysis. RESULTS: Deceased patients (30%) were older with higher body mass index (BMI), higher levels of LDH, NLR index, CRP and lower TL and lymphocytes count compared to survivors. Kaplan-Meier survival analysis showed six parameters were significant mortality predictors in the following order of significance: COVID-19 history, 2-years cardiovascular mortality risk score, NLR, TL, CRP, LDH. Using binary logistic regression analysis Summary risk score, a combination of these six parameters revealed as the best predictor of patient's survival in this group of parameters (log rank 25.4, p < 0.001). CONCLUSION: Compared to the general population, the mortality rate among HD patients persists at a higher level despite advancements in HD technology and patient care. The situation has been exacerbated by COVID-19, by significant increase in mortality rate among these patients.

The Specificity of Epizootic and Epidemiological Processes in Natural Foci of Hemorrhagic Fever with Renal Syndrome and Tick-Borne Encephalitis in Russia, as the Basis for the Prospects of Creating a Combined Vaccine for the Prevention of These Infections.

Hemorrhagic fever with renal syndrome (HFRS) and tick-borne encephalitis (TBE) are the most common viral diseases in Russia. HFRS is caused by six different types of hantaviruses: Hantaan, Amur, Seoul, Puumala, Kurkino, and Sochi, which are transmitted to humans through small mammals of the Muridae and Cricetidae families. TBE is caused by viruses belonging to five different phylogenetic subtypes. The similarities in the ecology of HFRS and TBE pathogens is presented here. Hantavirus-infected small mammals can transmit the virus to uninfected animals, and ticks can also transmit hantavirus to other ticks and mammals. Hantavirus transmission from ticks to humans is possible only hypothetically based on indirect data. Over the past 23 years, 164,582 cases of HFRS (4.9 per 105 people) and 71,579 cases of TBE (2.5 per 105 people) were registered in Russia. The mortality rate was 0.4% (668 cases) in HFRS and 1.6% deaths (1136 cases) in TBE. There were 4030 HFRS (2.5%) and 9414 TBE (13%) cases in children under 14 years old. HFRS and TBE cases were registered in 42 out of 85 Russian regions; in 18-only HFRS, in 13-only TBE, and 12 had no reported cases. The prospects of applying a combined vaccine for HFRS and TBE prevention are shown in this paper.

Analysis of the causes of neonatal death and genetic variations in congenital anomalies: a multi-center study.

Background: Neonatal deaths often result from preventable conditions that can be addressed with appropriate interventions. This study aims to analyze the distribution of the causes of neonatal death and explore genetic variations that lead to congenital anomalies in Northwest China. Methods: This multi-center observational study was conducted across six medical centers in Shaanxi province, Northwest China. Clinical data were retrospectively collected from neonates admitted between 2016 and 2020. Kaplan-Meier analysis was utilized to estimate survival rates, while high-throughput sequencing platforms were employed to detect mutations causing congenital anomalies. Results: Among 73,967 neonates requiring hospital care, 424 neonatal deaths were recorded, leading to a neonatal mortality rate of 0.57%. The primary causes of death included neonatal respiratory distress syndrome (23.8%), birth asphyxia (19.8%), neonatal septicemia (19.3%), and congenital anomalies (13.6%). The leading causes of neonatal deaths due to congenital anomalies were congenital heart defects (38.6%), bronchopulmonary dysplasia (14.0%), and inherited metabolic disorders (10.5%). Genetic analysis identified 83 pathogenic or likely pathogenic variants in 23 genes among the neonates with congenital anomalies, including four novel mutations (c.4198+1G>T, c.1075delG, c.610-1G>A, c.7769C>T) in the ABCC8, CDKL5, PLA2G6, and NIPBL genes. Conclusion: Congenital anomalies represent a significant and preventable cause of neonatal deaths in Northwest China. Early detection of congenital anomalies through genetic testing and comprehensive prenatal care are crucial for reducing neonatal mortality rates and improving pregnancy outcomes.

Alzheimer's Disease Mortality Rate: Correlation with Socio-Economic and Environmental Factors.

The progressive increase in the number of deaths caused by Alzheimer's disease (AD) in Brazil and around the world between 2010 and 2020 raises questions in scientific society. At the same time, there is also an increase in life expectancy at birth (LEB). Thus, the aim of this study was, for the first time, to compare the increase in AD mortality rate (ADMR) in Brazilian regions over the years 2010 to 2020 with the increase in LEB, and investigate the possible correlation between these demographic transition phenomena and pesticide sales and exposure during this period. Data were extracted from the Brazilian Institute of Geography and Statistics (IBGE), from the Department of Informatics and Technology of the Brazilian Ministry of Health (DATASUS) and from the Brazilian Institute of the Environment and Renewable Natural Resources (IBAMA). There was a significant increase in life expectancy at birth and in ADMR over the years between 2010 and 2020 in all Brazilian regions, with the female population in the South region being the most affected. In conclusion, there is a strong positive correlation between the increase in ADMR and LEB; ADMR and Human Development Index (HDI) and ADMR and pesticide sales and exposure in Brazil over the years studied.

Influence of Breast Cancer Awareness Month on Public Interest of Breast Cancer in High-Income Countries Between 2012 and 2022: Google Trends Analysis.

BACKGROUND: Breast cancer is the most common cancer among women worldwide. High-income countries have a greater incidence and mortality rate of breast cancer than low-income countries. As a result, raising awareness about breast cancer is crucial in increasing the chances of early detection and treatment. Social media has evolved into an essential tool for Breast Cancer Awareness Month campaigns, allowing people to share their breast cancer stories and experiences while also providing a venue for education and support. OBJECTIVE: The aim of this study was to assess the level of public interest in searches linked to breast cancer among a sample of high-income nations with a sizable internet user base from 2012 to 2022. We also sought to compare the proportional search volume for breast cancer during Breast Cancer Awareness Month with that during other months of the year. METHODS: Google Trends was used to retrieve data on internet user search behaviors in the context of breast cancer from 2012 to 2022. Seven countries were evaluated in this study: Australia, Canada, Ireland, New Zealand, the United Kingdom, Saudi Arabia, and the United States, in addition to global data. Breast cancer relative search volume trends were analyzed annually, monthly, and weekly from 2012 to 2022. The annual percent change (APC) was calculated for each country and worldwide. Monthly and weekly data were used to identify potential trends. RESULTS: A fluctuating pattern in APC rates was observed, with a notable increase in 2018 and a significant decrease in 2020, particularly in Saudi Arabia. Monthly analysis revealed a consistent peak in search volume during October (Breast Cancer Awareness Month) each year. Weekly trends over a 20-year period indicated significant decreases in Australia, Canada, New Zealand, and the United States, while increases were noted in Ireland. Heatmap analysis further highlighted a consistent elevation in median search volume during October across all countries. CONCLUSIONS: These findings underscore the impact of Breast Cancer Awareness Month and suggest potential influences of governmental COVID-19 pandemic control measures in 2020 on internet search behavior.
