Persistence and misuse of antibiotics eventually give rise to the progression of resistance development in bacteria. Consequently, accurate, fast and cost-effective sensing devices are required to govern the presence of drugs. Herein, we design a microfluidic paper-based device (μPAD) for the detection of Rifampicin. We selected this analyte because of its persistent overuse for the treatment of tuberculosis, among the major causes of death around the world. In this work, we have integrated Fe-reinforced ZnS nanoparticles supported with rifampicin (RIF) imprinted material on the exterior of Whatman filter paper for the fabrication of paper-based microfluidic device (μPAD). In this fabricated μPAD colorimetric detection was performed, and the synergistic effect of Fe and ZnS was recorded as compared to individual nanomaterials. A distinct color indicator was used to quantify the concentration of the targeted substance by the naked eye. The fabricated paper-based sensor possessed high sensitivity for rifampicin detection, recorded linear calibration curve representing 0.1 µM LOD and excellent selectivity, in comparison to other inferring agents present in real samples. The practical application of this designed μPAD was validated by applying a real sample. [ABSTRACT FROM AUTHOR]

Organ donation following circulatory determination of death (DCDD) has contributed significantly to the donor pool in several countries, without compromising the outcomes of transplantation or the number of donations following brain death (BD). In India, majority of deceased donations happen following BD. While existing legislation allows for DCDD, there have been only a few reports of kidney transplantation following DCDD from the country. This document, prepared by a multi-disciplinary group of experts, reviews the international best practices in DCDD and outlines the path for furthering the same in India. The ethical, medical, legal, economic, procedural, and logistic challenges unique to India for all types of DCDD based on the Modified Maastricht Criteria have been addressed. India follows an opt-in system for organ donation that does not allow much scope for uncontrolled DCDD categories I and II. The practice of withdrawal of life-sustaining treatment (WLST) in India is in its infancy. The process of WLST, laid down by the Supreme Court of India, is considered time-consuming, possible only in patients in a permanent vegetative state, and considered too cumbersome for day-to-day practice. In patients where continued medical care is determined to be futile following detailed and repeated assessment, the procedure for WLST, as laid down and published by Vidhi Centre for Legal Policy in conjunction with leading medical experts is described. In controlled DCDD (category-III), the decision for WLST is independent of and delinked from the subsequent possibility of organ donation. Once families are inclined toward organ donation, they are explained the procedure including the timing and location of WLST, consent for antemortem measures, no-touch period, and the possibility of stand down and return to the intensive care unit without donation. While donation following neurologic determination of death (DNDD) is being increasingly practiced in the country, there are instances where the cardiac arrest occurs during the process of declaration of BD, before organ retrieval has been done. Protocol for DCDD category-IV deals with such situations and is described in detail. In DCDD category V, organ donation may be possible following unsuccessful cardiopulmonary resuscitation of cardiac arrest in the intensive care. An outline of organ-specific requisites for kidney, liver, heart, and lung transplantation following DCDD and the use of techniques such as normothermic regional perfusion and ex vivo machine perfusion has been provided. With increasing experience, the outcomes of transplantation following DCDD are comparable to those following DBDD or living donor transplantation. Documents and checklists necessary for the successful execution of DCDD in India are described. [ABSTRACT FROM AUTHOR]

Background The Medical Certificate of Stillbirth (MCS) records data about a baby's death after 24 weeks of gestation but before birth. Major errors that could alter interpretation of the MCS were widespread in two UK-based regional studies. Methods A multicentre evaluation was conducted, examining MCS issued 1 January 2018 to 31 December 2018 in 76 UK obstetric units. A systematic case-note review of stillbirths was conducted by Obstetric and Gynaecology trainees, generating individual 'ideal MCSs' and comparing these to the actual MCS issued. Anonymized central data analysis described rates and types of error, agreement and factors associated with major errors. Results There were 1120 MCSs suitable for assessment, with 126 additional submitted data sets unsuitable for accuracy analysis (total 1246 cases). Gestational age demonstrated 'substantial' agreement [K = 0.73 (95% CI 0.70–0.76)]. Primary cause of death (COD) showed 'fair' agreement [K = 0.26 (95% CI 0.24–0.29)]. Major errors [696/1120; 62.1% (95% CI 59.3–64.9%)] included certificates issued for fetal demise at <24 weeks' gestation [23/696; 3.3% (95% CI 2.2–4.9%)] or neonatal death [2/696; 0.3% (95% CI 0.1–1.1%)] or incorrect primary COD [667/696; 95.8% (95% CI 94.1–97.1%)]. Of 540/1246 [43.3% (95% CI 40.6–46.1%)] 'unexplained' stillbirths, only 119/540 [22.0% (95% CI 18.8–25.7%)] remained unexplained; the majority were redesignated as either fetal growth restriction [FGR: 195/540; 36.1% (95% CI 32.2–40.3%)] or placental insufficiency [184/540; 34.1% (95% CI 30.2–38.2)]. Overall, FGR [306/1246; 24.6% (95% CI 22.3–27.0%)] was the leading primary COD after review, yet only 53/306 [17.3% (95% CI 13.5–22.1%)] FGR cases were originally attributed correctly. Conclusion This study demonstrates widespread major errors in MCS completion across the UK. MCS should only be completed following structured case-note review, with particular attention on the fetal growth trajectory. [ABSTRACT FROM AUTHOR]

Stroke, a vascular disease of the brain, is the #1 cause of disability and a major cause of death worldwide. Stroke has a major negative impact on the life of stroke-affected individuals, their families and the society. A significant proportion of stroke victims indicate that would have preferred death over their after-stroke quality of life. Mechanical thrombectomy (MT), opening the occluded artery using mechanical aspiration or a thrombus-entrapment device, is a guideline-mandated (class I, level of evidence A) treatment modality in patients with large vessel occlusion stroke. MT clinical benefit magnitude indicates that a universal access to this treatment strategy should be the standard of care. Today there is a substantial geographic variation in MT deliverability, with large-scale disparities in MT implementation. In many countries effective access to MT remains severely limited. In addition, many of the MT-treated patients are treated too late for a good functional outcome because of logistic delays that include transportations to remotely located, scarce, comprehensive stroke centres. Position Paper from the European Society of Cardiology Council on Stroke and European Association for Percutaneous Cardiovascular Interventions on interdisciplinary management of acute ischaemic stroke, developed with the support of the European Board of Neurointervention fills an important gap in systematically enabling interventional cardiologists to support stroke intervention in the geographic areas of unmet needs in particular. We review strengths and weaknesses of the document, and suggest directions for the next steps that are swiftly needed to deliver MT to stroke patients more effectively. [ABSTRACT FROM AUTHOR]

Cardiovascular disease is the leading cause of death of women in the United States, yet cardiovascular research is disproportionately conducted using male human subjects and male animal models. This article deploys Katrina Hutchison's (2019) analysis of gender disparity in clinical trials as a moral aggregation problem to address the problem of underrepresentation of women in cardiovascular research. I identify cost concerns, convenience, pregnancy, and negligence as potential reasons for the underrepresentation of women in CVD research. Finally, I suggest that multilevel strategies will be needed to eliminate sex disparity in CVD research and improve patient care. [ABSTRACT FROM AUTHOR]

Sudden unexpected death of an individual with epilepsy can pose a challenge to death investigators, as most deaths are unwitnessed, and the individual is commonly found dead in bed. Anatomic findings (eg, tongue/lip bite) are commonly absent and of varying specificity, thereby limiting the evidence to implicate epilepsy as a cause of or contributor to death. Thus it is likely that death certificates significantly underrepresent the true number of deaths in which epilepsy was a factor. To address this, members of the National Association of Medical Examiners, North American SUDEP Registry, Epilepsy Foundation SUDEP Institute, American Epilepsy Society, and the Centers for Disease Control and Prevention constituted an expert panel to generate evidence-based recommendations for the practice of death investigation and autopsy, toxicological analysis, interpretation of autopsy and toxicology findings, and death certification to improve the precision of death certificate data available for public health surveillance of epilepsy-related deaths. The recommendations provided in this paper are intended to assist medical examiners, coroners, and death investigators when a sudden unexpected death in a person with epilepsy is encountered.

Antimicrobial resistance (AMR), the ability of a bacterial species to resist the action of an antimicrobial drug, has been on the rise due to the widespread use of antimicrobial agents. Per the World Health Organization, AMR has an estimated annual cost of USD 34 billion in the US and is predicted to be the number one cause of death worldwide by 2050. One way AMR bacteria can spread, and by which individuals can contract AMR infections, is through contaminated water. Monitoring AMR bacteria in the environment currently requires that samples be transported to a central laboratory for slow and labor intensive tests. We have developed an inexpensive assay using paper-based analytical devices (PADs) that can test for the presence of β-lactamase-mediated resistance. To demonstrate viability, the PAD was used to detect β-lactam resistance in wastewater and sewage and identified resistance in individual bacterial species isolated from environmental water sources.

The ongoing COVID‐19 pandemic caused by SARS‐CoV‐2 has caused widespread deaths, illnesses, and societal disruption. I describe here how I pivoted a discussion‐based senior biology capstone course to include a multiweek module surrounding one primary literature paper on the evolution of SARS‐CoV‐2 and the subsequent scientific discourse about the paper. Using a gradual reveal of the paper following the CREATE method (consider, read, elucidate, and think of the next experiment), I challenged students to learn new evolutionary principles and critically analyze the data surrounding the evolution and transmission of SARS‐CoV‐2 presented in the paper. I also provide general advice for implementing this module in future courses. [ABSTRACT FROM AUTHOR]

Background: Electronic death certification was established in France in 2007. A methodology based on intrinsic characteristics of death certificates was designed to compare the quality of electronic versus paper death certificates. Methods: All death certificates from the 2010 French mortality database were included. Three specific quality indicators were considered: (i) amount of information, measured by the number of causes of death coded on the death certificate; (ii) intrinsic consistency, explored by application of the International Classification of Disease (ICD) General Principle, using an international automatic coding system (Iris); (iii) imprecision, measured by proportion of death certificates where the selected underlying cause of death was imprecise. Multivariate models were considered: a truncated Poisson model for indicator (i) and binomial models for indicators (ii) and (iii). Adjustment variables were age, gender, and cause, place, and region of death. Results: 533,977death certificates were analyzed. After adjustment, electronic death certificates contained 19% [17%-20%] more codes than paper death certificates for people deceased under 65 years, and 12% [11%-13%] more codes for people deceased over 65 years. Regarding deceased under and over 65 respectively, the ICD General Principle could be applied 2% [0%-4%] and 6% [5%-7%] more to electronic than to paper death certificates. The proportion of imprecise death certificates was 51% [46%-56%] lower for electronic than for paper death certificates. Conclusion: The method proposed to evaluate the quality of death certificates is easily reproducible in countries using an automatic coding system. According to our criteria, electronic death certificates are better completed than paper death certificates. The transition to electronic death certificates is positive in many aspects and should be promoted. [ABSTRACT FROM AUTHOR]

Objective The aim of this research was to compare the risk of all-cause mortality and mortality from all cancers combined, lung cancer, respiratory diseases, cardiovascular diseases and diabetes mellitus between normal-weight smokers and overweight or obese ex-smokers. Methods Data were from 1997 to 2004 National Health Interview Survey (with response rates ranging from 70% to 80%) which were linked to records in the National Death Index. Mortality follow-up was through 31 December 2006. The sample was limited to normal-weight smokers and overweight/obese ex-smokers 25 years of age and older (n=52 819). HR from Cox regression was computed to represent mortality effect. Results Results showed that in both women and men, normal-weight smokers, relative to overweight or obese ex-smokers, had a higher risk of mortality from all causes combined, all cancers combined, lung cancer, cardiovascular and respiratory diseases. Among women, there was no difference in mortality risk from diabetes mellitus between normal-weight smokers and overweight or obese ex-smokers. Among men, there was some evidence that the risk of mortality was higher in obese ex-smokers than normal-weight smokers. Conclusions This article concludes that, overall, mortality risk is smaller in overweight or obese ex-smokers than normal-weight smokers. Smoking cessation interventions can tailor messages that highlight the greater reduction in mortality associated with quitting, compared with potential weight gain. [ABSTRACT FROM AUTHOR]

Cardiovascular diseases are the leading cause of death, globally. Stroke and heart attacks account for more than 80% of cardiovascular disease-related deaths. To prevent patient mismanagement and potentially save lives, effective screening at an early stage is needed. Diagnosis is typically made using an electrocardiogram (ECG) analysis. However, ECG recordings are often corrupted by different types of noise, degrading the quality of the recording and making diagnosis more difficult. This paper reviews research on automatic ECG quality assessment techniques used in studies published from 2012–2022. The CinC11 Dataset is most often used for training and testing algorithms. Only one study tested its algorithm on people in real-time, but it did not specify the demographic data of the subjects. Most of the reviewed papers evaluated the quality of the ECG recordings per single lead. The accuracy of the algorithms reviewed in this paper range from 85.75% to 97.15%. More clarity on the research methods used is needed to improve the quality of automatic ECG quality assessment techniques and implement them in a clinical setting. This paper discusses the possible shortcomings in current research and provides recommendations on how to advance the field of automatic ECG quality assessment. [ABSTRACT FROM AUTHOR]

The 11th Revision of the International Statistical Classification of Diseases, Injuries, and Causes of Death (ICD-11) will replace its predecessor as international standard for cause-of death-statistics. The digitization of healthcare is a main motivation for its introduction. In parallel, the replacement of the paper-based death certificate with an electronic format is under evaluation. At the moment, the death certificate is used in paper-based format with ICD-10 for coding in Germany. To be prepared for the switch to ICD-11, the compatibility between ICD-11 and the electronic certificate should be assured. Objectives were to check the appropriateness of diagnosis-related information found on death certificates for an ICD-11 coding and to describe enhancements to the certificate's structure needed to fully utilize the strengths of ICD-11. As part of an exploratory test of a respective application, information from 453 electronic death certificates were provided by one local health authority. From a sample of 200 certificates, 433 diagnosis texts were coded into the German version of ICD-11. The appropriateness of the results as well as the further requirements of ICD-11, particularly with regard to post-coordination, were checked. For 430 diagnosis texts, 649 ICD-11 codes were used. Three hundred and sixty two diagnosis texts were rated as appropriately represented through the coding result. Almost all certificates contained diagnosis texts that lacked details required by ICD-11 for a precise coding. The distribution of diseases was very similar between ICD-10 and ICD-11 coding. A few gaps in ICD-11 were identified. Information requested by ICD-11 for a mandatory post-coordination were almost entirely absent from the death certificates. The structure and content of the death certificate are currently not well prepared for an ICD-11 coding. Necessary information was frequently missing. The line-oriented structure of death certificates has to be supplemented with a more flexible approach. Then, the semantic knowledge base of ICD-11 should better guide the content related input fields of a future electronic death certificate. [ABSTRACT FROM AUTHOR]

Transmission of cytomegalovirus (CMV) to seronegative, immunocompromised recipients can cause serious and fatal complications. Although the seroprevalence of CMV is high, the risk of primary CMV infection among healthy blood donors has not yet been analysed in a large population. We developed an algorithm to determine the rate of CMV seroconversion in an overall cohort of 24 260 subjects who donated 176 474 blood units during an 11-year observation period. We detected CMV seroconversion in all relevant age groups (18–60 years) with an overall seroconversion rate of 0·55% per year. Both CMV seroconversion and seroprevalence occurred more frequently in female donors ( P = 0·02 and P < 0·001, respectively). We identified 30–35-year-old blood donors as the group with the highest rate of CMV seroconversion per year (1·33% vs. 0·46%; P < 0·0001). We conclude that the risk of primary CMV infection is a continuous lifelong event and correlates with age and female gender. [ABSTRACT FROM AUTHOR]

Background: Liver disease is a growing health concern and a major cause of death. It causes multiple symptoms, including financial, psychological and social issues. To address these challenges, palliative care can support people alongside active treatment, and towards the end of life, but little is known about the care experiences of individuals with liver disease in the United Kingdom. This review aimed to explore the palliative and end‐of‐life care experiences of people with liver disease in the United Kingdom. Method: A systematic review was conducted using a five‐stage process and following Preferred Reporting Items for Systematic Reviews and Meta Analyses guidelines. Searches were across Web of Science, Scopus, EBSCO and grey literature until 10 May 2023. The review was registered through International Prospective Register of Systematic Reviews (PROSPERO). NVivo 12.5 was used to facilitate data analysis (systematic review registration: PROSPERO CRD42022382649). Results: Of 6035 papers (excluding duplicates) found from searches, five met the inclusion criteria of primary research related to adults with liver disease receiving palliative and/or end‐of‐life care in the United Kingdom, published in English. Reflexive thematic analysis of the data was conducted. The themes identified were the experiences of people with liver disease of relating to healthcare professionals, using services, receiving support, and experiences of information and communication. These were connected by an overarching concept of disempowerment versus empowerment, with the notion of person‐centred care as an important feature. Conclusion: This review has found variations in the care experiences of people with advanced liver disease towards the end of life and an overall lack of access to specialist palliative care services. Where services are designed to be person‐centred, experiences are more empowering. Further research is needed but with recognition that it is often unclear when care for people with liver disease is palliative or end‐of‐life. Patient and Public Contribution: An online public involvement workshop was held on 18 April 2023 through Voice (2023). This included four people with liver disease and four carers to discuss the review findings and to design a qualitative research study to further explore the topic. [ABSTRACT FROM AUTHOR]

Simple Summary: Determining the time and cause of death in forensic investigations is challenging when remains are highly decomposed, making traditional toxicological samples unreliable. Entomotoxicology, a controversial and underinvestigated field in forensic science, uses insect specimens from cadavers as alternative toxicological samples. Research has shown that insects feeding on decomposing tissues can serve as substrate for toxicological analyses, which can detect drugs, toxins, and elements even at low concentrations. Nevertheless, the correlation of drug concentrations between insects and conventional matrices is controversial due to unknown factors affecting drug metabolism. This paper examines four real cases where human cadavers were in advanced decomposition, and toxicological analyses were performed on both insect samples and available matrices. The findings provide insights into the correlation between larvae and human specimen results, adding to the limited literature on entomotoxicology in real cases. Additionally, this paper offers guidelines for collecting and preserving entomological evidence at crime scenes and during autopsies for use in entomotoxicological analyses. This advancement shows promise in enhancing forensic investigations, particularly in cases where traditional methods are inapplicable or require additional validation. In forensic investigation, determining the time and cause of death becomes challenging, especially in cases where the remains are found in advanced decomposition, rendering traditional toxicological samples unavailable or unreliable. Entomotoxicology, an emerging methodology within forensic science, leverages insect specimens collected from cadavers as alternative toxicological samples. Several laboratory and field research studies have highlighted the efficacy in detecting various drugs, toxins, and elements absorbed by insects feeding on cadaveric tissues, even at low concentrations. However, correlation studies between drug concentrations in conventional matrices and insects remain controversial due to unknown factors influencing drug metabolism and larval feeding activity. This paper presents four real cases in which human cadavers were discovered in advanced stages of decomposition, and toxicological analyses were performed on both insect samples and available matrices. The results presented complement the scant literature currently available on the application of entomotoxicology in real cases, providing insights into the correlation between larvae and human specimen results. Furthermore, guidelines to collect and preserve entomological evidence at the crime scene and during the autopsy for use in entomotoxicological analyses are provided. This advancement holds promise in aiding forensic investigations, particularly in cases where traditional methods cannot be applied or require supporting data for further validation.

Background: There is increasing interest in using verbal autopsy to produce nationally representative populationlevel estimates of causes of death. However, the burden of processing a large quantity of surveys collected with paper and pencil has been a barrier to scaling up verbal autopsy surveillance. Direct electronic data capture has been used in other large-scale surveys and can be used in verbal autopsy as well, to reduce time and cost of going from collected data to actionable information. Methods: We collected verbal autopsy interviews using paper and pencil and using electronic tablets at two sites, and measured the cost and time required to process the surveys for analysis. From these cost and time data, we extrapolated costs associated with conducting large-scale surveillance with verbal autopsy. Results: We found that the median time between data collection and data entry for surveys collected on paper and pencil was approximately 3 months. For surveys collected on electronic tablets, this was less than 2 days. For small-scale surveys, we found that the upfront costs of purchasing electronic tablets was the primary cost and resulted in a higher total cost. For large-scale surveys, the costs associated with data entry exceeded the cost of the tablets, so electronic data capture provides both a quicker and cheaper method of data collection. Conclusions: As countries increase verbal autopsy surveillance, it is important to consider the best way to design sustainable systems for data collection. Electronic data capture has the potential to greatly reduce the time and costs associated with data collection. For long-term, large-scale surveillance required by national vital statistical systems, electronic data capture reduces costs and allows data to be available sooner. [ABSTRACT FROM AUTHOR]

Introduction Drowning is a leading cause of unintentional death. Rivers are a common location for drowning. Unlike other location-specific prevention efforts (home swimming pools and beaches), little is known about prevention targeting river drowning deaths. Methods A systematic literature review was undertaken using English language papers published between 1980 and 2014, exploring gaps in the literature, with a focus on epidemiology, risk factors and prevention strategies for river drowning. Results Twenty-nine papers were deemed relevant to the study design including 21 (72.4%) on epidemiology, 18 (62.1%) on risk factors and 10 (34.5%) that proposed strategies for prevention. Risk factors identified included age, falls into water, swimming, using watercraft, sex and alcohol. Discussion Gaps were identified in the published literature. These included a lack of an agreed definition for rivers, rates for fatal river drowning (however, crude rates were calculated for 12 papers, ranging from 0.20 to 1.89 per 100 000 people per annum), and consensus around risk factors, especially age. There was only one paper that explored a prevention programme; the remaining nine outlined proposed prevention activities. There is a need for studies into exposure patterns for rivers and an agreed definition (with consistent coding). Conclusions This systematic review has identified that river drowning deaths are an issue in many regions and countries around the world. Further work to address gaps in the published research to date would benefit prevention efforts. [ABSTRACT FROM AUTHOR]

Most of the cases (80.79%) were accidental in nature. [ABSTRACT FROM AUTHOR]

Sepsis is a dysregulated immune response to an infection that leads to organ dysfunction. Sepsis-associated organ dysfunction involves multiple inflammatory mechanisms and complex metabolic reprogramming of cellular function. These mechanisms cooperate through multiple organs and systems according to a complex set of long-distance communications mediated by cellular pathways, solutes, and neurohormonal actions. In sepsis, the concept of organ crosstalk involves the dysregulation of one system, which triggers compensatory mechanisms in other systems that can induce further damage. Despite the abundance of studies published on ​​organ crosstalk in the last decade, there is a need to formulate a more comprehensive framework involving all organs to create a more detailed picture of sepsis. In this paper, we review the literature published on organ crosstalk in the last 10 years and explore how these relationships affect the progression of organ failure in patients with septic shock. We explored these relationships in terms of the heart–kidney–lung, gut-microbiome–liver–brain, and adipose tissue–muscle–bone crosstalk in sepsis patients. A deep connection exists among these organs based on crosstalk. We also review how multiple therapeutic interventions administered in intensive care units, such as mechanical ventilation, antibiotics, anesthesia, nutrition, and proton pump inhibitors, affect these systems and must be carefully considered when managing septic patients. The progression to multiple organ dysfunction syndrome in sepsis patients is still one of the most frequent causes of death in critically ill patients. A better understanding and monitoring of the mechanics of organ crosstalk will enable the anticipation of organ damage and the development of individualized therapeutic strategies.

BACKGROUND: One of the main illnesses in the globe that causes impairment and death in people is stroke. In the globe today, it ranks as the second leading cause of death and the leading cause of death in China. OBJECTIVE: This paper analyses into the critical role of risk perception in developing individual awareness of stroke risk and encouraging proactive preventive health behaviors, essential for effective primary stroke prevention strategies and reduced stroke incidence. It discusses the concept of risk perception, the content and dimensions of global stroke assessment tools, and their application status, aiming to provide insights for their development and intervention research. METHODS: Risk perception encompasses subjective assessments of stroke likelihood and severity, influenced by personal experiences, knowledge of risk factors, beliefs about prevention effectiveness, and emotional responses. Global stroke assessment tools, like the Framingham Stroke Risk Score and CHA2DS2-VASc Score, evaluate stroke risk based on factors such as age, gender, blood pressure, and cholesterol levels. In order to improve risk perception and proactive health management and lower the burden of strokes, the paper assesses the advantages and disadvantages of these tools and makes recommendations for improving accessibility, customizing interventions, running educational campaigns, promoting multidisciplinary collaboration, and integrating technology. RESULTS: By combining the research tools of stroke risk perception, it is found that the evaluation tools are mostly single-dimensional evaluation tools centered on the two dimensions of onset possibility and susceptibility. CONCLUSION: Some scholars have developed multi-dimensional evaluation tools, but the evaluation population is relatively limited, and the evaluation system lacks comprehensiveness and systematization.

Labelled 'the shadow pandemic' by UN Women, violence against women received considerable global public attention during 2020–21. Underpinning this moment of public concern, there lies a substantial history of efforts to document the nature of, and campaign against, the extent of violence against women globally. This is also the case in relation to femicide. Whilst we recognise that this is a contested term, for the purposes of this paper we use femicide to refer to the killing of women and girls because they are female by male violence. Femicide, as a death to be specifically counted in law only exists in a small number of jurisdictions. Where it is so recognised, primarily in South American countries as feminicidio, such deaths represent only the tip of the iceberg of such killings globally. This paper, in drawing on empirical data from a range of different sources (including administrative data, media analysis, and Femicide Observatory data) gathered throughout 2020, considers: what it means to call a death femicide, what implications might follow if all the deaths of women at the hands of men were counted as femicide, and the extent to which extraordinary times have any bearing on this kind of ordinary death.

Purpose: More than 20 years ago we reported an analysis of a case series of elderly critically ill patients with acute kidney injury (AKI)--then termed acute renal failure. At that time, AKI was regarded as a "simple" complication, but has since undergone a fundamental change and actually has become one of the central syndromes in the critically ill patient.Methods: We have analyzed elderly patients above 65 years of age with an AKI defined as serum creatinine above 3 mg/dl corresponding to modern KDIGO stage 3, most of them requiring renal replacement therapy (RRT). Using an extremely complete data set the diagnosis differentiated the underlying disease entity, the dominant cause of AKI, acute and chronic risk factors (comorbidities). Special aspects such as severity of disease, early AKI at admission versus late AKI, early versus later start of RRT, AKI not treated by RRT in spite of indication for RRT, various measures of short-term and long-term prognosis, renal outcome, patients dying with resolved AKI, and causes of death were evaluated.Results: Crude mortality was 61% which corresponds to modern studies with gross variation among the different subgroups. Age per se was not a determinant of survival either within the group of elderly patients or as compared to younger age groups. Despite an increase in mean age and disease severity during the observation period prognosis improved. A total of 17% of patients developed a chronic kidney disease. Long-term survival as compared to the general population was low.Conclusions: A look back at the last two decades illustrates a remarkable evolution or rather metamorphosis of a syndrome. AKI has evolved as a central syndrome in intensive care patients, a systemic disease process associated with multiple systemic sequels and extra-renal organ injury and exerting a pronounced effect on the course of disease and short- and long-term prognosis not only of the patient but also of the kidney. Moreover, the "non-renal-naïve" elderly patient with multiple comorbidities has become the most frequent ICU patient in industrialized nations. [ABSTRACT FROM AUTHOR]

The annual incidence of stroke has continued to rise, establishing it as the leading cause of mortality and permanent disability globally. The quality improvement of discharge planning is essential throughout the development of discharge planning, which guarantees a seamless transition of care for stroke patients and family preparedness. This systematic review aimed to analyze the development of discharge planning and its impact on stroke patients and their families. The research was conducted and reported in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Eligible pieces of literature were compiled from seven electronic databases, i.e., ScienceDirect, Scopus, PubMed, EBSCOhost, ProQuest, SAGE Journals, and Google Scholar. The literature search was performed using predetermined search terms, with specific criteria that included papers exclusively published in English and studies conducted in 2018–2022. This study included eleven eligible papers, from which we identified three distinct approaches to the development of discharge planning. Firstly, seven articles recommended a conventional approach, which involved specific educational intervention with interactive learning methods through booklets, textbooks, and PowerPoint presentations. Secondly, two articles supported the use of a technology-based approach through audiovisual media or applications to deliver health information. Thirdly, two articles endorsed a family-centered nursing approach that focused on empowering families to deliver health information to the patient. The development of discharge planning showed a significant impact on stroke patients, as it could influence various aspects of their quality of life. This included improvements in physiological function, enhanced cognitive knowledge, increased satisfaction and self-efficacy, reduced stress levels and care burden, and the opportunity for families to adequately prepare for home-based patient care. This study concluded that integrating conventional with technology-based media is effective for developing discharge plans for stroke patients. The implementation of this novel approach in a health system can improve patient outcomes, family preparedness when providing care, and the quality of hospital care. [ABSTRACT FROM AUTHOR]

Purpose: Nowadays, systematic literature reviews (SLRs) and meta-analyses are often placed at the top of the study hierarchy of evidence. The main objective of this paper is to evaluate the trends in SLRs of randomized controlled trials (RCTs) throughout the years. Methods: Medline database was searched, using a highly focused search strategy. Each paper was coded according to a specific ICD-10 code; the number of RCTs included in each evaluated SLR was also retrieved. All SLRs analyzing RCTs were included. Protocols, commentaries, or errata were excluded. No restrictions were applied. Results: A total of 7,465 titles and abstracts were analyzed, from which 6,892 were included for further analyses. There was a gradual increase in the number of annual published SLRs, with a significant increase in published articles during the last several years. Overall, the most frequently analyzed areas were diseases of the circulatory system (n = 750) and endocrine, nutritional, and metabolic diseases (n = 734). The majority of SLRs included between 11 and 50 RCTs each. Conclusions: The recognition of SLRs' usefulness is growing at an increasing speed, which is reflected by the growing number of published studies. The most frequently evaluated diseases are in alignment with leading causes of death and disability worldwide. [ABSTRACT FROM AUTHOR]

When a cervicocerebral dissection syndrome (CDS) is amongst the potential causes of death, investigation of the arteries is required. Whilst the proximal common carotid arteries (CCA) are relatively easy to interrogate at post-mortem (PM), assessment of the vertebral arteries (VA) is more challenging. Post-mortem selective cervical angiography (PM-SCA) provides a method to visualise these arteries to replace or guide further dissection. Our institution does not have dedicated radiological facilities; we are reliant on availability in the general hospital of both equipment and staffing. In addition, there is an expectation of the release of the body within 24 h. Therefore, our methods have to be time-efficient, flexible and suitable for available staff. The current paper aims to describe the indications for the procedure, the method as completed in our institution, imaging findings and problem solving. [ABSTRACT FROM AUTHOR]

Background: The Curamericas/Guatemala Maternal and Child Health Project, 2011–2015, implemented the Census-Based, Impact-Oriented Approach, the Care Group Approach, and the Community Birthing Center Approach. Together, this expanded set of approaches is known as CBIO+. This is the fifth of 10 papers in our supplement describing the Project and the effectiveness of the CBIO+ Approach. This paper assesses causes, levels, and risk factors for mortality along with changes in mortality. Methods: The Project maintained Vital Events Registers and conducted verbal autopsies for all deaths of women of reproductive age and under-5 children. Mortality rates and causes of death were derived from these data. To increase the robustness of our findings, we also indirectly estimated mortality decline using the Lives Saved Tool (LiST). Findings: The leading causes of maternal and under-5 mortality were postpartum hemorrhage and pneumonia, respectively. Home births were associated with an eight-fold increased risk of both maternal (p = 0.01) and neonatal (p = 0.00) mortality. The analysis of vital events data indicated that maternal mortality declined from 632 deaths per 100,000 live births in Years 1 and 2 to 257 deaths per 100,000 live birth in Years 3 and 4, a decline of 59.1%. The vital events data revealed no observable decline in neonatal or under-5 mortality. However, the 12–59-month mortality rate declined from 9 deaths per 1000 live births in the first three years of the Project to 2 deaths per 1000 live births in the final year. The LiST model estimated a net decline of 12, 5, and 22% for maternal, neonatal and under-5 mortality, respectively. Conclusion: The baseline maternal mortality ratio is one of the highest in the Western hemisphere. There is strong evidence of a decline in maternal mortality in the Project Area. The evidence of a decline in neonatal and under-5 mortality is less robust. Childhood pneumonia and neonatal conditions were the leading causes of under-5 mortality. Expanding access to evidence-based community-based interventions for (1) prevention of postpartum hemorrhage, (2) home-based neonatal care, and (3) management of childhood pneumonia could help further reduce mortality in the Project Area and in similar areas of Guatemala and beyond.

Problem: Many communities refer to sorcery or witchcraft to explain misfortunes such as sickness, death and disability. The effects of these beliefs on public health service delivery have long been overlooked. Beliefs in sorcery and witchcraft are significant challenges for health-care workers to understand to deliver better health outcomes and avoid inadvertently triggering accusations of witchcraft that may lead to violence. Context: This paper examines the impacts of accusations of sorcery and related violence on the provision of health care in Papua New Guinea. Action: The discussion focuses on a workshop held in Papua New Guinea in September 2022 with health extension officers on the topic of health-care delivery and sorcery accusations. Lessons learned: The workshop confirmed the challenges that beliefs in sorcery and witchcraft present for health extension officers and suggested several strategies that could be used to navigate them. It identified several possible future measures that those on the front line of community health-care delivery considered most important in responding to the issue. These included educating health-care workers on how to effectively address sorcery beliefs when delivering health care and developing communication techniques on the causes of death and sickness that avoid triggering sorcery accusations. Discussion: This paper reviews the findings of the workshop in the broader context of the effects of beliefs in witchcraft on public health delivery globally. Because of the close connections between sorcery beliefs and health, equipping health-care workers and field epidemiologists with strategies to address these beliefs effectively is critical to delivering better health care, facilitating timely response to public health events, and helping to prevent violence related to sorcery accusations. This need exists in all countries where sorcery beliefs related to health, illness, disability and death are prevalent. [ABSTRACT FROM AUTHOR]

The US Environmental Protection Agency (EPA) bases its estimate of the value of statistical life (VSL) on 17 hedonic wage studies and five contingent valuation studies conducted between 1974 and 1991. We summarize advances in the mortality risk valuation literature since these papers were published, focusing on studies conducted in the United States that value risks to adults. We review hedonic wage, other revealed preference, and stated preference studies, identifying papers that satisfy appropriate validity criteria. We conclude that the recent literature is sufficiently rich to permit a revision of EPA's baseline estimate. Importantly, VSL estimates from both the averting behavior and stated preference studies we review reflect the preferences of a wider range of demographic groups than the current VSL, and newer studies better target causes of death relevant to EPA regulations.

Atherosclerosis is a common form of cardiovascular disease, which is one of the most prevalent causes of death worldwide, particularly among older individuals. Surgery is the mainstay of treatment for severe stenotic lesions, though the rate of restenosis remains relatively high. Current medication therapy for atherosclerosis has limited efficacy in reversing the formation of atherosclerotic plaques. The search for new drug treatment options is imminent. Some potent medications have shown surprising therapeutic benefits in inhibiting inflammation and endothelial proliferation in plaques. Unfortunately, their use is restricted due to notable dose-dependent systemic side effects or degradation. Nevertheless, with advances in nanotechnology, an increasing number of nano-related medical applications are emerging, such as nano-drug delivery, nano-imaging, nanorobots, and so forth, which allow for restrictions on the use of novel atherosclerotic drugs to be lifted. This paper reviews new perspectives on the targeted delivery of nanoparticles to blood vessels for the treatment of atherosclerosis in both systemic and local drug delivery. In systemic drug delivery, nanoparticles inhibit drug degradation and reduce systemic toxicity through passive and active pathways. To further enhance the precise release of drugs, the localized delivery of nanoparticles can also be accomplished through blood vessel wall injection or using endovascular interventional devices coated with nanoparticles. Overall, nanotechnology holds boundless potential for the diagnosis and treatment of atherosclerotic diseases in the future. [ABSTRACT FROM AUTHOR]

Simple Summary: Breast cancer is a significant cause of female cancer-related deaths in the US. Checking how severe the cancer is helps in planning treatment. Modern AI methods are good at grading cancer, but they are not used much in hospitals yet. We developed and utilized ensemble deep learning algorithms for addressing the tasks of classifying (1) breast cancer subtype and (2) breast cancer invasiveness from whole slide image (WSI) histopathology slides. The ensemble models used were based on convolutional neural networks (CNNs) known for extracting distinctive features crucial for accurate classification. In this paper, we provide a comprehensive analysis of these models and the used methodology for breast cancer diagnosis tasks. Cancer diagnosis and classification are pivotal for effective patient management and treatment planning. In this study, a comprehensive approach is presented utilizing ensemble deep learning techniques to analyze breast cancer histopathology images. Our datasets were based on two widely employed datasets from different centers for two different tasks: BACH and BreakHis. Within the BACH dataset, a proposed ensemble strategy was employed, incorporating VGG16 and ResNet50 architectures to achieve precise classification of breast cancer histopathology images. Introducing a novel image patching technique to preprocess a high-resolution image facilitated a focused analysis of localized regions of interest. The annotated BACH dataset encompassed 400 WSIs across four distinct classes: Normal, Benign, In Situ Carcinoma, and Invasive Carcinoma. In addition, the proposed ensemble was used on the BreakHis dataset, utilizing VGG16, ResNet34, and ResNet50 models to classify microscopic images into eight distinct categories (four benign and four malignant). For both datasets, a five-fold cross-validation approach was employed for rigorous training and testing. Preliminary experimental results indicated a patch classification accuracy of 95.31% (for the BACH dataset) and WSI image classification accuracy of 98.43% (BreakHis). This research significantly contributes to ongoing endeavors in harnessing artificial intelligence to advance breast cancer diagnosis, potentially fostering improved patient outcomes and alleviating healthcare burdens.

According to data from the World Health Organization (WHO), cancer is considered to be one of the leading causes of death worldwide, and new therapeutic approaches, especially improved novel cancer treatment regimens, are in high demand. Considering that many chemotherapeutic drugs tend to have poor pharmacokinetic profiles, including rapid clearance and limited on-site accumulation, a combined approach with tumor-homing peptide (THP)-functionalized magnetic nanoparticles could lead to remarkable improvements. This is confirmed by an increasing number of papers in this field, showing that the on-target peptide functionalization of magnetic nanoparticles improves their penetration properties and ensures tumor-specific binding, which results in an increased clinical response. This review aims to highlight the potential applications of THPs in combination with magnetic carriers across various fields, including a pharmacoeconomic perspective. [ABSTRACT FROM AUTHOR]

This study was retrospectively registered with the OSF Registries on the 14 March 2024. [ABSTRACT FROM AUTHOR]

This paper aims to extend the Besag model, a widely used Bayesian spatial model in disease mapping, to a non-stationary spatial model for irregular lattice-type data. The goal is to improve the model's ability to capture complex spatial dependence patterns and increase interpretability. The proposed model uses multiple precision parameters, accounting for different intensities of spatial dependence in different sub-regions. We derive a joint penalized complexity prior to the flexible local precision parameters to prevent overfitting and ensure contraction to the stationary model at a user-defined rate. The proposed methodology can be used as a basis for the development of various other non-stationary effects over other domains such as time. An accompanying R package fbesag equips the reader with the necessary tools for immediate use and application. We illustrate the novelty of the proposal by modeling the risk of dengue in Brazil, where the stationary spatial assumption fails and interesting risk profiles are estimated when accounting for spatial non-stationary. Additionally, we model different causes of death in Brazil, where we use the new model to investigate the spatial stationarity of these causes. [ABSTRACT FROM AUTHOR]

Cerebral infarction is a common neurological disease with high rates of morbidity, mortality, and recurrence, posing a great threat to human life and health. Cerebral infarction is the second leading cause of death in the world and the leading cause of long-term disability in humans. The results of the third national retrospective sampling survey on causes of death in 2008 showed that cerebral infarction has become the leading cause of death in China and its mortality rate is 4–5 times that of European and American countries. Therefore, this article proposed a study on the predictive value of Cmmi-MHR combined with thromboelastography parameters that was performed for acute cerebral infarction. This paper mainly proposed a high frame rate imaging technology and analyzed its algorithm. In this article, in the experimental part, an in-depth analysis of the predictive value of the Monocyte-to-high-density lipoprotein cholesterol ratio (MHR) combined with thromboelastography parameters was performed for acute cerebral infarction. The final experimental results showed that HDL (OR = 1.695%, P-trend = 0.049) had a probability of death within 90 days of hospitalization (OR = 0.81, 95% CI = 1.06–3.11, P-trend = 0.523). There were no significant differences in mortality rate after 90 days. Regardless of adjusting for confounders such as age, gender, and NIHSS score, there was no significant difference in the risk of MHR or monocyte count within 90 days of hospitalization. The conclusion indicates that the combination of Cmmi-MHR and thromboelastography parameters provides a new perspective and method for the diagnosis and treatment of cerebral infarction, and provides important support for personalized treatment and management of cerebral infarction.

Evidence of an insulin overdose is very complicated in the medico-legal field. The analysis and subsequent interpretation of results is complex, especially when treating postmortem blood samples. The instability of insulin, the special pre-analytical conditions and the absence of specific analytical methods has led most laboratories not to analyze insulin in their routine with a consequent underestimation of cases. This paper aims to assess the difficulties associated with the analytical characterization of insulin by describing a case that typically represents most of the inconveniences encountered following a suspected insulin overdose. The case concerns a man found dead at home by his brother. After an external examination, which did not reveal a specific cause of death, toxicological analysis was requested which did not reveal any substance of toxicological interest. Only 9 months later, it was reported to the toxicologist that the subject was diabetic, on insulin lispro treatment and that three empty syringes were found next to his body. Following analysis by LC-high-resolution mass spectrometry, the presence of insulin lispro at a concentration of 1.1 ng/mL, a therapeutic concentration, was evidenced. Despite the low concentration found, overdose cannot be excluded and this paper will describe the criteria evaluated to reach this conclusion. This case highlights that the interpretation of a postmortem insulin concentration is very complex and requires the evaluation of various elements including the circumstances of death, the subject's medical history, the interval between death and sampling and the sample storage.

Metastases are complications of primary tumors due to prolonged cancer survival and have become an important issue for oncological patients and the most frequent cause of death and disability. Bone metastases occur at a later stage of cancer disease, and the spine is the most frequent site. To date, the aim of the treatment of metastases remains to be the control of disease and provide a satisfactory quality of life. The decision making of treatment is influenced by several factors such as the status of the primary disease, the number of metastases, site involvement, and the performance status of the patients. For this reason, the treatment of metastases is challenging and undergoes constant development. Therefore, alternative techniques with respect to surgery, which is the first option but not always practicable, and radiochemotherapy are attractive. Lately, electrochemotherapy has emerged as an innovative method for treating various primary and metastatic solid tumors, showing promising outcomes in terms of inducing tumor tissue necrosis and alleviating symptoms. This technique uses electric pulses to increase the uptake of chemotherapy by tumor cells. Despite the initial enthusiasm and good results in the treatment of bone tumors, relatively few papers have described its use in spine metastases. Therefore, we conducted a systemic review of this intriguing topic while also reporting our experience in the use of electrochemotherapy for the treatment of spine metastases. [ABSTRACT FROM AUTHOR]

Purpose: In England and Wales, Domestic Homicide Reviews (DHRs) are conducted into domestic abuse-related killings. In 2016, deaths by suicide were brought into the scope of this review system and, to distinguish them from reviews into domestic homicides, we describe these as 'Suicide Domestic Abuse-Related Death Reviews' (S-DARDR). To date, S-DARDRs have been little considered and, in response, this empirical paper seeks to unpack this process. Method: In a larger study, 40 DHR participants were interviewed, and a reflexive thematic analysis was undertaken. 18 participants discussed S-DARDRs. These interviews were re-read, with relevant extracts identified and re-analysed thematically. Through a shared critical reflection, we drew on our practice experience to interrogate the themes generated from the interviews and offer insight into the underlying challenges. Results: From the interviews, we generated four themes relating to commissioning and delivery; the involvement of stakeholders; intersections with other statutory processes; and purpose. Based on our shared critical reflection, we identified the underlying challenges as an under conceptualisation of S-DARDRs, alongside their de-mooring from the criminal justice system. Taken together, these challenges have implications for the conduct of S-DARDRs. We identify recommendations for policy and practice to address these challenges. Conclusion: The development of S-DARDRs has been little considered and challenges arise around when and how they should be undertaken. A shared understanding of key concepts and expectations around delivery is necessary if S-DARDRs are to enable robust learning and be a driver for systems change while also being accessible and understood by all stakeholders.

This paper utilises empirical data to explore the value of 'body work' performed by last responders charged with the duty of dead body management, with a focus on the Global South. While frontline staff work to save lives, little is known about the experiences and roles of those who care for the dead in global health in times of crises and even during normal times. This paper discusses ethical and socio-cultural challenges pathologists face in 'working on the bodies of others' while conducting any form of post-mortem procedures – necessary for ascertaining and recording the causes of death. Identifying and reporting the cause of death have significant public health benefits and provide closure for bereaved families. Despite the foregoing, the pathology field does not attract funding from governments or donors, and it is overlooked compared to other disciplines. Autopsy procedure bears social stigma – as it is associated with body mutilation and therefore disrespecting the dead; certain cultural beliefs or taboos about impurity and death persist, further raising some social and ethical tensions. As a result, the dearth of autopsy procedures contributes to the cause of death uncertainty in global health. [ABSTRACT FROM AUTHOR]

Alzheimer's disease (AD) is considered as one of the leading causes of death among people over the age of 70 that is characterized by memory degradation and language impairment. Due to language dysfunction observed in individuals with AD patients, the speech-based methods offer non-invasive, convenient, and cost-effective solutions for the automatic detection of AD. This paper systematically reviews the technologies to detect the onset of AD from spontaneous speech, including data collection, feature extraction and classification. First the paper formulates the task of automatic detection of AD and describes the process of data collection. Then, feature extractors fromspeech data and transcripts are reviewed, whichmainly contains acoustic features fromspeech and linguistic features from text. Especially, general handcrafted features and deep embedding features are organized from different modalities. Additionally, this paper summarizes optimization strategies for AD detection systems. Finally, the paper addresses challenges related to data size, model explainability, reliability and multimodality fusion, and discusses potential research directions based on these challenges.

This paper introduces an emotion-based BDI (Belief, desire, intention) methodology to model decision-making during fire evacuation simulations while considering human emotions. The methodology is designed to represent human decision-making processes in graphical representations, which can be simply translated for the implementation phase to simulate various case studies. The methodology utilizes the Belief, Desire, and Intention architecture and the OCEAN Openness, Conscientiousness, Extraversion, Agreeableness, and Neuroticism) personality behavior to represent decision-making processes graphically, making it easy to translate into a simulation. The methodology aims to create a more realistic simulation closer to real human behavior by incorporating emotions that affect decision-making. In this paper, we validate the emotion-based BDI methodology by replicating the bushfire Australia case study and benchmarking with the previous work on BDI fire evacuation. From the comparison, we found that both results share almost similar patterns. The results show "dead while still unaware" (0% vs. 0%), "dead while deciding what to do" (69% vs. 48%), "dead while defending" (6% vs. 8%), and "dead while preparing to defend" (6% vs 28%), "dead while preparing to escape" (4% vs 0%) and "dead while escaping" (15% vs 20%). The results show that in our Simulation, there is a death related to preparing to escape (4% vs 0%). However, the other causes of death have an almost similar percentage of death causes. Hence, based on the comparison, supporting and validating our emotion-oriented simulation model is considered adequate. Therefore, this emotion-based BDI methodology can systematically reproduce human cognition and emotion. [ABSTRACT FROM AUTHOR]

Cardiovascular disease is currently the top global cause of death, however, research into new therapies is in decline. Tissue engineering is a solution to this crisis and in combination with the use of carbon nanotubes (CNTs), which have drawn recent attention as a biomaterial, could facilitate the development of more dynamic and complex in vitro models. CNTs’ electrical conductivity and dimensional similarity to cardiac extracellular proteins provide a unique opportunity to deliver scaffolds with stimuli that mimic the native cardiac microenvironment in vitro more effectively. This systematic review aims to evaluate the use and efficacy of CNTs for cardiac tissue scaffolds and was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines. Three databases were searched: PubMed, Scopus, and Web of Science. Papers resulting from these searches were then subjected to analysis against pre-determined inclusion and quality appraisal criteria. From 249 results, 27 manuscripts met the criteria and were included in this review. Neonatal rat cardiomyocytes were most commonly used in the experiments, with multiwalled CNTs being most common in tissue scaffolds. Immunofluorescence was the experimental technique most frequently used, which was employed for the staining of cardiac-specific proteins relating to contractile and electrophysiological function.

Cancer is one of the leading causes of death worldwide, making the search for alternatives for its control a critical issue. In this context, exploring alternatives from natural sources, such as certain vegetables containing a variety of secondary metabolites with beneficial effects on the body and that play a crucial role in the fight against cancer, is essential. Among the compounds with the greatest efficacy in controlling this disease, those with antioxidant activity, particularly phenolic com-pounds, stand out. A remarkable example of this group is protocatechuic acid (PCA), which has been the subject of various revealing research on its activities in different areas. These studies sustain that protocatechuic acid has anti-inflammatory, antimutagenic, antidiabetic, antiulcer, antiviral, antifibrogenic, antiallergic, neuroprotective, antibacterial, anticancer, antiosteoporotic, anti-aging, and analgesic properties, in addition to offering protection against metabolic syndrome and con-tributing to the preservation of hepatic, renal, and reproductive functionality. Therefore, this paper aims to review the biological activities of PCA, focusing on its anticancer potential and its in-volvement in the control of various molecular pathways involved in tumor development, sup-porting its option as a promising alternative for cancer treatment.

Suicide is a serious issue around the world and is a leading cause of death in US. In the past 20 years, the suicide rate has seen a significant increase of 35%. With the rapid development of information technology, more and more people begin to use social media to share their inner feelings. It enables social media data to be widely used for research on suicide risk assessment. However, not all social media posts are suicide related. Previous research addressed this problem with post-level attention mechanism. However, post-level attention mechanism may not find relevant suicide posts. This problem becomes more serious in the feature-based post embeddings since each post is converted into a single vector to serve as the input of the model, resulting in the loss of word-level information during training. In this paper, we addressed this problem by introducing a novel word-level model including a post-selectin layer as a solution. Firstly, we utilize a suicide keyword dictionary to identify risky posts that may be missed by the post-level attention mechanism. We then convert the words in the risky posts into word embeddings and use self-attention to generate the post embeddings for the risky posts. Finally, we pass the post embeddings to a multilayer perceptron to classify the suicide risk. We also demonstrate that the FScore used in previous studies can be reduced to a function of accuracy, which does not reflect the model performance in predicting imbalanced datasets. Therefore, we additionally adopt macro F1 score as the evaluation function. Experiment results show that our model not only outperforms previous studies in FScore performance, but also achieves macro F1 Score a nearly 4% improvement compared to previous studies.
