Emerging Pandemic Diseases: How We Got to COVID-19.

Infectious diseases prevalent in humans and animals are caused by pathogens that once emerged from other animal hosts. In addition to these established infections, new infectious diseases periodically emerge. In extreme cases they may cause pandemics such as COVID-19; in other cases, dead-end infections or smaller epidemics result. Established diseases may also re-emerge, for example by extending geographically or by becoming more transmissible or more pathogenic. Disease emergence reflects dynamic balances and imbalances, within complex globally distributed ecosystems comprising humans, animals, pathogens, and the environment. Understanding these variables is a necessary step in controlling future devastating disease emergences.

Role of Polyunsaturated Fat in Modifying Cardiovascular Risk Associated With Family History of Cardiovascular Disease: Pooled De Novo Results From 15 Observational Studies.

BACKGROUND: It is unknown whether dietary intake of polyunsaturated fatty acids (PUFA) modifies the cardiovascular disease (CVD) risk associated with a family history of CVD. We assessed interactions between biomarkers of low PUFA intake and a family history in relation to long-term CVD risk in a large consortium. METHODS: Blood and tissue PUFA data from 40 885 CVD-free adults were assessed. PUFA levels ≤25th percentile were considered to reflect low intake of linoleic, alpha-linolenic, and eicosapentaenoic/docosahexaenoic acids (EPA/DHA). Family history was defined as having ≥1 first-degree relative who experienced a CVD event. Relative risks with 95% CI of CVD were estimated using Cox regression and meta-analyzed. Interactions were assessed by analyzing product terms and calculating relative excess risk due to interaction. RESULTS: After multivariable adjustments, a significant interaction between low EPA/DHA and family history was observed (product term pooled RR, 1.09 [95% CI, 1.02-1.16]; P=0.01). The pooled relative risk of CVD associated with the combined exposure to low EPA/DHA, and family history was 1.41 (95% CI, 1.30-1.54), whereas it was 1.25 (95% CI, 1.16-1.33) for family history alone and 1.06 (95% CI, 0.98-1.14) for EPA/DHA alone, compared with those with neither exposure. The relative excess risk due to interaction results indicated no interactions. CONCLUSIONS: A significant interaction between biomarkers of low EPA/DHA intake, but not the other PUFA, and a family history was observed. This novel finding might suggest a need to emphasize the benefit of consuming oily fish for individuals with a family history of CVD.

Optimised stacked machine learning algorithms for genomics and genetics disorder detection in the healthcare industry.

With recent advances in precision medicine and healthcare computing, there is an enormous demand for developing machine learning algorithms in genomics to enhance the rapid analysis of disease disorders. Technological advancement in genomics and imaging provides clinicians with enormous amounts of data, but prediction is still mostly subjective, resulting in problematic medical treatment. Machine learning is being employed in several domains of the healthcare sector, encompassing clinical research, early disease identification, and medicinal innovation with a historical perspective. The main objective of this study is to detect patients who, based on several medical standards, are more susceptible to having a genetic disorder. A genetic disease prediction algorithm was employed, leveraging the patient's health history to evaluate the probability of diagnosing a genetic disorder. We developed a computationally efficient machine learning approach to predict the overall lifespan of patients with a genomics disorder and to classify and predict patients with a genetic disease. The SVM, RF, and ETC are stacked using two-layer meta-estimators to develop the proposed model. The first layer comprises all the baseline models employed to predict the outcomes based on the dataset. The second layer comprises a component known as a meta-classifier. Results from the experiment indicate that the model achieved an accuracy of 90.45% and a recall score of 90.19%. The area under the curve (AUC) for mitochondrial diseases is 98.1%; for multifactorial diseases, it is 97.5%; and for single-gene inheritance, it is 98.8%. The proposed approach presents a novel method for predicting patient prognosis in a manner that is unbiased, accurate, and comprehensive. The proposed approach outperforms human professionals using the current clinical standard for genetic disease classification in terms of identification accuracy. The implementation of stacked will significantly improve the field of biomedical research by improving the anticipation of genetic diseases.

Clinical Interviewing: An Essential but Neglected Method of Medicine.

Clinical interviewing is the basic method to understand how a person feels and what are the presenting complaints, obtain medical history, evaluate personal attitudes and behavior related to health and disease, give the patient information about diagnosis, prognosis, and treatment, and establish a bond between patient and physician that is crucial for shared decision making and self-management. However, the value of this basic skill is threatened by time pressures and emphasis on technology. Current health care trends privilege expensive tests and procedures and tag the time devoted to interaction with the patient as lacking cost-effectiveness. Instead, the time spent to inquire about problems and life setting may actually help to avoid further testing, procedures, and referrals. Moreover, the dialogue between patient and physician is an essential instrument to increase patient's motivation to engage in healthy behavior. The aim of this paper was to provide an overview of clinical interviewing and its optimal use in relation to style, flow and hypothesis testing, clinical domains, modifications according to settings and goals, and teaching. This review points to the primacy of interviewing in the clinical process. The quality of interviewing determines the quality of data that are collected and, eventually, of assessment and treatment. Thus, interviewing deserves more attention in educational training and more space in clinical encounters than it is currently receiving.

Additive interaction of family medical history of diabetes with hypertension on the diagnosis of diabetes among older adults in India: longitudinal ageing study in India.

BACKGROUND: The present study aimed to estimate the additive interaction of family history of diabetes and hypertension on the diagnosis of diabetes among individuals aged 45 years and above in India. The coexistence of these two exposures may act synergistically on the risk of diabetes, leading to adverse health outcomes. METHODS: The study utilized the data from the Longitudinal Ageing Study in India (LASI) Wave 1 (2017-2018). The total sample size for the current study was 58,612 individuals aged 45 years and above. Multivariable logistic regression models were employed to determine the individual and joint effect of a family history of diabetes with hypertension on diabetes. An additive model was applied to assess the interaction effect of the family medical history of diabetes with hypertension on the diagnosis of diabetes by calculating three different measures of additive interaction such as the relative excess risk ratio (RERI), attribution proportion due to interaction (AP), and synergy index (S). RESULTS: The prevalence of diabetes was three times higher among individuals with family history of diabetes (27.8% vs. 9.2%) than those without family history. Individuals with family history of diabetes (AOR: 2.47, CI: 2.11 2.89) had 2.47 times higher odds of having diabetes than those without family history. The prevalence of diabetes was significantly higher among individuals with hypertension and family history of diabetes (46.6%, 95% CI: 39.7-53.6) than those without the coexistence of family history of diabetes and hypertension (9.9%, 95% CI: 9.5-10.4), individuals with hypertension and without a family history of diabetes (22.7%, 95% CI: 21.2-24.2), and individuals with family history of diabetes and without hypertension (16.5%, 95% CI: 14.5-18.7). Moreover, the adjusted odds ratio (AOR) of the joint effect between family medical history of diabetes and hypertension on diabetes was 9.28 (95% CI: 7.51-11.46). In the adjusted model, the RERI, AP, and S for diabetes were 3.5 (95% CI: 1.52-5.47), 37% (0.37; 95% CI: 0.22-0.51), and 1.69 (95% CI: 1.31-2.18) respectively, which indicates that there is a significant positive interaction between family history of diabetes and hypertension on the diagnosis of diabetes. The study findings on interaction effects further demonstrate consistent results for two models of hypertension (self-reported hypertension and hypertensive individuals receiving medication) even after adjustment with potential confounding factors on diabetes (self-reported diabetes and individuals with diabetes receiving medication). CONCLUSIONS: The study findings strongly suggest that the interaction of family history of diabetes with hypertension has a positive and significant effect on the risk of diabetes even after adjustment with potential confounding factors. Furthermore, the findings indicate a synergistic effect, emphasizing the importance of considering both family medical history of diabetes and hypertension when assessing diabetes risk and designing preventive strategies or interventions.

A computational clinical decision-supporting system to suggest effective anti-epileptic drugs for pediatric epilepsy patients based on deep learning models using patient's medical history.

BACKGROUND: Epilepsy, a chronic brain disorder characterized by abnormal brain activity that causes seizures and other symptoms, is typically treated using anti-epileptic drugs (AEDs) as the first-line therapy. However, due to the variations in their modes of action, identification of effective AEDs often relies on ad hoc trials, which is particularly challenging for pediatric patients. Thus, there is significant value in computational methods capable of assisting in the selection of AEDs, aiming to minimize unnecessary medication and improve treatment efficacy. RESULTS: In this study, we collected 7,507 medical records from 1,000 pediatric epilepsy patients and developed a computational clinical decision-supporting system for AED selection. This system leverages three multi-channel convolutional neural network (CNN) models tailored to three specific AEDs (vigabatrin, prednisolone, and clobazam). Each CNN model predicts whether a respective AED is effective on a given patient or not. The CNN models showed AUROCs of 0.90, 0.80, and 0.92 in 10-fold cross-validation, respectively. Evaluation on a hold-out test dataset further revealed positive predictive values (PPVs) of 0.92, 0.97, and 0.91 for the three respective CNN models, representing that suggested AEDs by our models would be effective in controlling epilepsy with a high accuracy and thereby reducing unnecessary medications for pediatric patients. CONCLUSION: Our CNN models in the system demonstrated high PPVs for the three AEDs, which signifies the potential of our approach to support the clinical decision-making by assisting doctors in recommending effective AEDs within the three AEDs for patients based on their medical history. This would result in a reduction in the number of unnecessary ad hoc attempts to find an effective AED for pediatric epilepsy patients.

Spotlight on El-Zahrawi, Father of Modern Surgery: Reflections on His Impact on Contemporary Medicine and the Need for Greater Medical Education on Pivotal Figures in Medicine.

Issue: For students in the preclinical years of medical school, it is easy to overlook the narrative component of medicine and become occupied with learning the vast sea of information about the human body. There are limited, if any, options to learn about historical figures in medicine and how they can inform our future in clinical medicine. Evidence: There is an apparent lack of education offered on pivotal figures in medicine across many institutions. The few instances that medical history has been incorporated into the curriculum are further discussed. Implications: In order to incorporate cultural competency in our delivery of care, it is important to consider the diversity of the population we will be serving and how we can prepare to help patients feel heard in their unique issues. In this paper, we propose learning about the true history of certain medical practices, rather than the "colonial" version often utilized in textbooks and lectures, as a means of diversifying students' perspectives of the origins of these practices as well as giving credit where it is due. The time period during which many of these medical practices were cultivated is referred to as the Islamic Golden Age, but scholars who made contributions belonged to many different faiths and cultural backgrounds. El-Zahrawi was a Muslim physician whose principal work, Kitab-at-Tasrif, contains topics on medicine, surgery, midwifery, pharmacology, therapeutics, diet, psychotherapy, and medical chemistry. He pioneered numerous techniques in surgery and invented surgical devices that are still used to this day.

Dick van Velzen and the Burnside warehouse organ scandal in Nova Scotia, Canada.

Dick van Velzen practiced as a pediatric pathologist at Alder Hey Children's Hospital in Liverpool, England from September 1988 until December 1995; he then relocated to the IWK-Grace Health Centre, a children's and maternity hospital in Halifax, Nova Scotia, Canada, where he practiced until he was fired for cause in January 1998. About a year and a half later, his practice in Liverpool came under increasing scrutiny, with the initial focus on the massive collection of post-mortem pediatric organs he had accumulated for planned future research on sudden infant death syndrome. Soon, a Parliamentary Inquiry began investigating the full scope of his Liverpool practice. During the Inquiry, another organ-hoarding scandal erupted; van Velzen, when leaving Halifax after his dismissal, had put his family's personal belongings into a storage facility at Burnside Industrial Park and then did not pay bills. As his belongings were being prepared for auction, formalin-fixed organs were found, and a Canada-wide arrest warrant for disrespect for human remains was issued by the Halifax Police. While the Alder Hey scandal resulted in a 535-page-long Parliamentary Report and the Human Tissue Act, van Velzen was never charged criminally in the UK. The largely unknown story of his second organ scandal in Halifax, is related here. Although he had obtained the body parts with the consent of the parents of the child to which they had belonged, his failure to properly identify and store them traumatized parents already impacted by his organ-hoarding in the UK, traumatized additional parents in Halifax, and resulted in significant waste of public resources in investigating the case. He pled guilty to "indignity to a human body" in Canada and was fined and placed on 12 months' probation.

Dental implant considerations in patients with systemic diseases: An updated comprehensive review.

BACKGROUND: Various medical conditions and the drugs used to treat them have been shown to impede or complicate dental implant surgery. It is crucial to carefully monitor the medical status and potential post-operative complications of patients with systemic diseases, particularly elderly patients, to minimize the risk of health complications that may arise. AIM: The purpose of this study was to review the existing evidence on the viability of dental implants in patients with systemic diseases and to provide practical recommendations to achieve the best possible results in the corresponding patient population. METHODS: The information for our study was compiled using data from PubMed, Scopus, Web of Science and Google Scholar databases and searched separately for each systemic disease included in our work until October 2023. An additional manual search was also performed to increase the search sensitivity. Only English-language publications were included and assessed according to titles, abstracts and full texts. RESULTS: In total, 6784 studies were found. After checking for duplicates and full-text availability, screening for the inclusion criteria and manually searching reference lists, 570 articles remained to be considered in this study. CONCLUSION: In treating patients with systemic conditions, the cost-benefit analysis should consider the patient's quality of life and expected lifespan. The success of dental implants depends heavily on ensuring appropriate maintenance therapy, ideal oral hygiene standards, no smoking and avoiding other risk factors. Indications and contraindications for dental implants in cases of systemic diseases are yet to be more understood; broader and hardcore research needs to be done for a guideline foundation.

[Diagnostic workup for polyneuropathy]. / Diagnostische Abklärung bei Polyneuropathie.

Polyneuropathy is a disease of the peripheral nervous system that usually results in distally emphasized, often symmetrical sensory and motor stimulation and deficits. These are often extremely painful. They can be divided into hereditary and acquired causes; inflammatory and infectious causes should be further differentiated among the acquired causes. A careful diagnostic workup is essential. Clinical signs and distribution patterns of symptoms can often already provide clues to the underlying aetiology. This review describes this workup, which in addition to the medical history and clinical examination always includes thorough laboratory diagnostics, electrophysiological examination and cerebrospinal fluid diagnostics. In individual cases, further diagnostic steps may be necessary in order to make the correct diagnosis.

Pattern of bioterrorism in ancient times: lessons to be learned from the microbial and toxicological aspects.

The current research aimed to analyze the history of bioterrorism in antiquity and to adapt the data to modern medical knowledge. To this end, a thorough evaluation of the literature related to the ancient history of bioterrorism and modern data was done using the Web of Sciences, Science Direct, Scopus, PubMed, and Google Scholar. Results showed that knowledge of bioterrorism has existed since antiquity in different civilizations. Biological and toxicological agents were used as an instrument of legal execution, as a warfare tool in battles, or to eliminate political rivals across nations. Ancient people researched bioterrorism to apply it against enemies and at the same time provide countermeasures in favor of themselves and allies. Despite the existence of the principles of bioterrorism since ancient times, adaptation of the data to modern research can assist in planning countermeasure efforts, preventive actions, and treatments in the framework of modern counterterrorism medicine.

The "oldest and the newest of nurses": Nursing and the Professionalization of Obstetrics and Gynecology.

When in the late nineteenth century American physicians increasingly replaced midwives in the care of obstetrical and gynecological patients, they could do so only because they were aided by another emerging group of healthcare professionals: nurses. Nurses were instrumental in assisting physicians in the care of patients in labor and during recovery. They were also necessary for male physicians because the vast majority of nurses were women and their presence during gynecological and obstetrical treatments made it more socially acceptable for men to examine female patients. In hospital schools in the northeast and through long-distance nursing programs, physicians taught students about obstetrical nursing and instructed them to protect the modesty of female patients. They also tried to instill strict professional hierarchies between nurses and physicians, emphasizing that nurses should never attempt to deliver a patient without a physician. But as nursing emerged into a unique professional practice separate from that of physicians, nurses were able to negotiate better education in the care of laboring patients. In order to take over women's sexual and reproductive health care from traditional providers, physicians conceded to nurses' demands for more authority in patient care.

Patient and Clinician Sociodemographics and Sexual History Screening at a Multisite Federally Qualified Health Center: A Mixed Methods Study.

PURPOSE: In 2018, there were 68 million sexually transmitted infections in the United States. Sexual history screening is an evidence-based practice endorsed by guidelines to identify risk of these infections and adverse sexual health outcomes. In this mixed methods study, we investigated patient- and clinician-level characteristics associated with receipt of sexual history screening, and contextualized these differences in more depth. METHODS: We collected sociodemographics of patients from the electronic health record and sociodemographics of their primary care clinicians via a census survey. Semistructured interviews were conducted with key practice staff. We conducted multilevel crossed random effects logistic regression analysis and thematic analysis on quantitative and qualitative data, respectively. RESULTS: A total of 53,246 patients and 56 clinicians from 13 clinical sites participated. Less than one-half (42.4%) of the patients had any sexual history screening documented in their health record. Patients had significantly higher odds of documented screening if they were gay or lesbian (OR = 1.23), were cisgender women (OR = 1.10), or had clinicians who were cisgender women (OR = 1.80). Conversely, patients' odds of documented screening fell significantly with age (OR per year = 0.99) and with the number of patients their clinicians had on their panels (OR per patient = 0.99), and their odds were significantly lower if their primary language was not English (OR = 0.91). In interviews, key staff expressed discomfort discussing sexual health and noted assumptions about patients who are older, in long-term relationships, or from other cultures. Discordance of patient-clinician gender and patients' sexual orientation were also noted as barriers. CONCLUSIONS: Interventions are needed to address the interplay between the social and contextual factors identified in this study, especially those that elicited discomfort, and the implementation of sexual history screening.

Non-standard diagnostic assessment reliability in psychiatry: a study in a Brazilian outpatient setting using Kappa.

The use of Structured Diagnostic Assessments (SDAs) is a solution for unreliability in psychiatry and the gold standard for diagnosis. However, except for studies between the 50 s and 70 s, reliability without the use of Non-SDAs (NSDA) is seldom tested, especially in non-Western, Educated, Industrialized, Rich, and Democratic (WEIRD) countries. We aim to measure reliability between examiners with NSDAs for psychiatric disorders. We compared diagnostic agreement after clinician change, in an outpatient academic setting. We used inter-rater Kappa measuring 8 diagnostic groups: Depression (DD: F32, F33), Anxiety Related Disorders (ARD: F40-F49, F50-F59), Personality Disorders (PD: F60-F69), Bipolar Disorder (BD: F30, F31, F34.0, F38.1), Organic Mental Disorders (Org: F00-F09), Neurodevelopment Disorders (ND: F70-F99) and Schizophrenia Spectrum Disorders (SSD: F20-F29). Cohen's Kappa measured agreement between groups, and Baphkar's test assessed if any diagnostic group have a higher tendency to change after a new diagnostic assessment. We analyzed 739 reevaluation pairs, from 99 subjects who attended IPUB's outpatient clinic. Overall inter-rater Kappa was moderate, and none of the groups had a different tendency to change. NSDA evaluation was moderately reliable, but the lack of some prevalent hypothesis inside the pairs raised concerns about NSDA sensitivity to some diagnoses. Diagnostic momentum bias (that is, a tendency to keep the last diagnosis observed) may have inflated the observed agreement. This research was approved by IPUB's ethical committee, registered under the CAAE33603220.1.0000.5263, and the UTN-U1111-1260-1212.

Fiftieth Anniversary of Uncovering the Tuskegee Syphilis Study: The Story and Timeless Lessons.

This year marks the 50th anniversary of the uncovering of the Tuskegee syphilis study, when the public learned that the Public Health Service (precursor of the CDC) for 40 years intentionally withheld effective therapy against a life-threatening illness in 400 African American men. In 2010, we learned that the same research group had deliberately infected hundreds of Guatemalans with syphilis and gonorrhea in the 1940s, with the goal of developing better methods for preventing these infections. Despite 15 journal articles detailing the results, no physician published a letter criticizing the Tuskegee study. Informed consent was never sought; instead, Public Health Service researchers deceived the men into believing they were receiving expert medical care. The study is an especially powerful parable because readers can identify the key players in the narrative and recognize them as exemplars of people they encounter in daily life-these flesh-and-blood characters convey the principles of research ethics more vividly than a dry account in a textbook of bioethics. The study spurred reforms leading to fundamental changes in the infrastructure of research ethics. The reason people fail to take steps to halt behavior that in retrospect everyone judges reprehensible is complex. Lack of imagination, rationalization, and institutional constraints are formidable obstacles. The central lessons from the study are the need to pause and think, reflect, and examine one's conscience; the courage to speak; and above all the willpower to act. History, although about the past, is our best defense against future errors and transgressions.

Francis S. Morrison MD was among the early developers and promoters of the American Society for Apheresis (ASFA). His work was pivotal in creating a lasting institutional structure from which American apheresis medical practice would develop decades after his death. Francis Morrison is honored each year at the ASFA annual meeting as ASFA awards the Francis S. Morrison MD Memorial Award Lecture to an individual who stands out as among its most accomplished members. This tribute seeks to describe the person and the key accomplishments of Francis S. Morrison in the historical context of a time when the future of apheresis medicine was uncertain.

Dementia and the history of disease in older adults in community.

INTRODUCTION: Many studies have revealed the effect of medical history on dementia. The aim of this study was to explore the relationship between the history of disease and onset of dementia. METHODS: This was a multi-center, cross-sectional study, with 2595 older adults enrolled. The onset of dementia was evaluated with Revised Hasegawa Dementia Scale (HDS-R). The diagnosed diseases after the age of 40 of the participants were investigated, including respiratory system diseases, digestive system diseases, cardiovascular diseases, endocrine disorders, genitourinary system diseases, nervous system disease, sensory system diseases, dental/oral diseases, bone/joint diseases and mental illnesses. RESULTS: Data of 2458 older adults were analyzed. Univariate analysis showed that diabetes, thyroid disease, mental illness, hearing loss, stroke, dental/oral disease, Denture use, fracture/osteoporosis, kidney disease and number of diseases were risk factors for dementia. After controlling for demographic sociological variables, diabetes, dental/oral disease, and denture use were independent risk factors for dementia. Thyroid disease (P = 0.313), mental illnesses (P = 0.067), hearing loss (P = 0.595), stroke (P = 0.538), fractures/osteoporosis (P = 0.069), kidney disease (P = 0.168) were no longer significant to dementia. CONCLUSION: Diabetes, dental/oral disease and denture use were main risk factors for dementia.

Discovery of insulin 100 years on.

The discovery of insulin 100 years ago ranks among the greatest medical achievements ever. This sparked a revolution of scientific discovery and therapeutic intervention to treat people suffering with diabetes. A light was shone for other areas of medicine to illuminate what was possible with detailed scientific endeavour. There followed a range of firsts leading to the current time in which we now know more about this peptide hormone than almost any other protein in existence. This has allowed therapeutic advancement from a positon of knowledge leading to stunning innovation. This innovation is likely to lead to more physiological insulin replacement reducing the disease burden to individuals and society as whole.

Pain and its management: Dante's Divine Comedy.

Dante Alighieri died in 1321; therefore, 2021 is the 700th anniversary of his death. His best known work is the Divine Comedy, which explores Dante's journey through the three realms of the underworld. Each realm is associated with three different sensations: Inferno, bodily (pain); Purgatorio, acoustic (music); and Paradiso, visual (light). The progression of the painful experiences and the resolution through music and light mirror the modern understanding of pain and its management. Music has both direct and indirect benefits and can help with coping. Sunlight promotes well-being and self-awareness.
