Prolonged Life Expectancy Research Articles

Systemic anti-cancer therapy and anaesthesia: a narrative review.

Cancer research has revolutionised the treatment, quality of life and life expectancy of people living with cancer. Systemic anti-cancer treatments have expanded to involve not only cytotoxic drugs, but targeted drugs and immunotherapy. Although highly effective in many patients, these drugs can cause serious and sometimes life-threatening adverse reactions. As part of their treatment, many patients living with cancer will be offered both systemic anti-cancer therapy and surgery, and many patients will undergo recurrent episodes of both with the aims of cure, palliation or prolongation of life expectancy. It is important for anaesthetists to understand the effects of systemic anti-cancer therapy on their patients. An electronic literature search using was conducted in May 2024 for peer-reviewed articles in English. An initial search of the terms 'anaesthesia' and 'chemotherapy' revealed that existing review literature was tailored towards the neoadjuvant setting and prompted this review to include the complications of targeted therapies, emergency care and intra-operative administration of systemic anti-cancer therapy to reflect this evolving field. A narrative approach was taken to discuss common regimens and their complications. The review encompasses a wide range of sub-topics including pharmacology; physiology; peri-operative medicine; specialist surgery; adverse events; and safety. Data from multicentre trials that form the basis of current treatment regimens and practice were prioritised during the selection process. Smaller studies, case series and case reports were included to illustrate the rarer but clinically significant adverse effects of specific therapies. It is important for anaesthetists to have a comprehensive understanding of the effects of systemic anti-cancer therapies, including cytotoxic and immunotherapies. There are many potential toxicities and complications associated with these treatments, particularly in the context of emergency surgery and the administration of cytotoxic drugs within the operating theatre environment.

Diabetes mellitus in patients with myasthenia gravis: a systematic review and meta-analysis.

With the prolongation of life expectancy in patients with myasthenia gravis, the number of comorbidities is increasing. Diabetes mellitus is one of the main comorbidities faced by patients with myasthenia gravis. However, there is not enough epidemiological information on diabetes mellitus. Given these limitations, the purpose of this study was to review the prevalence of diabetes mellitus in patients with myasthenia gravis and whether the myasthenia gravis is associated with an increased risk of gestational diabetes mellitus. PubMed, Embase, and Web of Science were searched for articles published prior to February 2024. Endnote 21 software was used to manage all relevant records. Review Manager version 5.4 and Stata version 18.0 software were used for the statistical analysis. Funnel plots and Egger's test were used to assess publication bias. Twenty-four articles met the inclusion criteria and were included in the study. Among 23,516 myasthenia gravis patients, the prevalence of diabetes mellitus was 17% (95% CI 12~22%). In addition, the meta-analysis of the two studies showed that myasthenia gravis was significantly associated with an increased risk of gestational diabetes mellitus (OR = 1.56, 95% CI 1.26~1.93, p < 0.01). Among the comorbidities of myasthenia gravis patients, diabetes mellitus is common, and the risk of gestational diabetes mellitus is increased in myasthenia gravis patients. These findings remind us that diabetes mellitus seems to be an important issue in the clinical management of myasthenia gravis patients and requires more attention.

Evaluation of Infectious Agents in the Pediatric Palliative Care Unit

Aim: The use of broad-spectrum antibiotics, changes in patient profile, prolonged life expectancy, increased use of medical devices and technologies such as catheters, intravenous fluids, gastrostomy and tracheostomy have led to changes in the number and types of microorganisms isolated from infections and cultures. There are no data on infections seen in pediatric palliative care. The aim of this study was to determine the frequency of infections and the pathogens produced in culture, to identify the sites of growth and to review what should be done. Materials and Methods: This was planned as a cross-sectional, retrospective study between 11/18/2018 and 09/01/2023. Sociodemographic data, reason for hospitalization, number of hospitalizations, primary diagnoses, comorbid conditions, medical devices and technology used, time and place of culture, number of cultures, microorganisms grown and factors associated with culture growth were examined. Statistical analysis was performed with the SPSS 18.0 program. p

The Positive impact of Greenery on the Mental and Physical Health of the Elderly: A Case Study in the Design of a Hospital Garden

Abstract The positive effects of greenery on human health have been studied for centuries. Knowledge and application of these benefits can be used in hospitals and retirement homes. Residents of these facilities are often mentally or physically disabled; hence creating a suitable exterior area in accordance with the scientific findings of the health benefits of greenery could improve the mental and physical states of the elderly and improve overall living conditions. Nature has calming effects and soothes our minds by driving away attention from the stressful problems of everyday life. Green colour, sounds of birds, water, and leaves decrease levels of stress and contribute to mental well-being. Free access to nature or gardens decreases the bad tempers of the elderly and improves memory and the overall state of patients with dementia. It reduces anxiety and stress, which are precursors for cardiovascular diseases. It helps prevent fall-related injuries and improves mobility and cognitive function. Consequently, contact with nature improves the quality of life, decreases the need for taking medicine, and could prolong life expectancy. As a case study, we present a design of the revitalisation of a hospital garden for the elderly in Bratislava city district of Podunajské Biskupice. It puts the knowledge of these benefits and the needs of various types of patients to practice, so that the garden could be used as an effective healing tool and as a calming area for patients as well as the staff and visitors.

Comparing The Mediterranean and The Japanese Dietary Pattern in Relation to Longevity - A Narrative Review.

The Mediterranean dietary pattern (MDP) and Japanese dietary pattern (JDP) have received increasing attention from the scientific community and media, predominantly due to their association with increased longevity and health. Although similarities between the two dietary patterns are evident, a detailed comparison between them is still relatively unexplored. This narrative review aimed to explore the similarities and differences between the MDP and JDP in terms of longevity while also reflecting on the adoption of these diets by other populations outside their regions of origin. Both dietary patterns are plant-based, minimally processed, and sustainable for their respective regions and have been shown to significantly prolong life expectancy in different populations. Nevertheless, these dietary patterns also differ in terms of macronutrient ratios, food preparation and consumption and individual cultural characteristics of each population. Additionally, both dietary patterns are part of broader lifestyle patterns, which include other behaviors, such as abstaining from smoking, engaging in regular physical activity, having low stress levels and a sense of community, spirituality/religiousness and purpose. The promotion of these two dietary patterns should be implemented in other regions after considering cultural and socio-economical characteristics.

Non-AIDS defining cancers in HIV-infected individuals: a concise review

Non-acquired immunodeficiency syndrome (AIDS)-defining cancers (NADCs) present a growing concern in human immunodeficiency virus (HIV)-infected individuals, impacting morbidity and mortality rates. This paper synthesizes current epidemiological data and explores the multifaceted relationship between HIV infection and NADC risk. Epidemiological studies indicate a shifting landscape of cancer incidence among HIV-infected populations, with a notable rise in NADCs over recent decades. Factors such as prolonged life expectancy due to effective antiretroviral therapy (ART) and aging of the HIV-infected population contribute to this trend. Despite the overall decline in AIDS-defining cancers, NADCs have emerged as a significant cause of morbidity and mortality in HIV-infected individuals. Immunodeficiency, chronic inflammation, and oncogenic viral co-infections, such as human papillomavirus and hepatitis C virus, compound the risk of developing NADCs. Diagnostic challenges persist, with delayed detection and suboptimal management contributing to poor outcomes. Treatment modalities for NADCs in HIV-infected individuals require careful consideration, balancing cancer-directed therapy with potential interactions with ART and immune reconstitution. Prevention strategies, including cancer screening and lifestyle modifications, are crucial in mitigating the burden of NADCs in this population. As the landscape of HIV care continues to evolve, understanding the epidemiology and clinical characteristics of NADCs is imperative for optimizing clinical management and improving outcomes in HIV-infected individuals.

Personalized Stem Length Optimization in Hip Replacement: A Microscopic Perspective on Bone-Implant Interaction.

Total hip replacement (THR) surgery involves the removal of necrotic tissue and the replacement of the natural joint with an artificial hip joint. The demand for THR is increasing due to population aging and prolonged life expectancies. However, the uniform length and shape of artificial hip joints can cause stress shielding, leading to implant loosening and femoral fractures. These issues arise because these designs fail to account for the unique anatomical and biomechanical characteristics of individual patients. Therefore, this study proposes and validates a method to optimize stem length by considering bone microstructure and daily load. The results demonstrated that the optimal stem length varies with loading conditions and significantly reduces stress in the cortical bone while maintaining an appropriate strain energy in the cancellous bone, thereby preventing bone loss. These findings underscore the importance of patient-specific stem design for improving implant stability and clinical outcomes.

Pediatric Dental Care and Antibiotics: A Comprehensive Update

Abstract Antimicrobial agents, a foundational component of contemporary medical practice, have significantly transformed the management of microbial infections, effectively protecting human well-being and prolonging life expectancy. Nevertheless, this extraordinary advancement faces a mounting challenge in the form of antimicrobial resistance (AMR). The ongoing evolution of microorganisms to withstand the impact of these substances has led to a decline in the efficacy of formerly dependable treatments, thereby presenting a critical menace to medical progress and prompting an exigent need for action. This paper undertakes a comprehensive exploration of the utilisation and correct application of antimicrobials within the context of paediatric dental healthcare. By meticulously examining the intricate interplay between therapeutic efficacy and the emergence of AMR, the overview delves into the pivotal function these agents fulfil in both preventing and treating dental infections in young patients. In addition, this update sheds light on the potential repercussions stemming from improper prescription practices, unwarranted overutilisation and insufficient adherence to established guidelines.

The ageing of people living with cystic fibrosis: what to expect now?

The prognosis of people with cystic fibrosis (pwCF) has improved dramatically with the introduction of cystic fibrosis transmembrane conductance regulator (CFTR) modulators (CFTRm). The ageing of the cystic fibrosis (CF) population is changing the disease landscape with the emergence of different needs and increasing comorbidities related to both age and long-term exposure to multiple treatments including CFTRm. Although the number of pwCF eligible for this treatment is expected to increase, major disparities in care and outcomes still exist in this population. Moreover, the long-term impact of the use of CFTRm is still partly unknown due to the current short follow-up and experience with their use, thus generating some uncertainties. The future spread and initiation of these drugs at an earlier stage of the disease is expected to reduce the systemic burden of systemic inflammation and its consequences on health. However, the prolonged life expectancy is accompanied by an increasing burden of age-related comorbidities, especially in the context of chronic disease. The clinical manifestations of the comorbidities directly or indirectly associated with CFTR dysfunction are changing, along with the disease dynamics and outcomes. Current protocols used to monitor slow disease progression will need continuous updates, including the composition of the multidisciplinary team for CF care, with a greater focus on the needs of the adult population.

Potential roles of lipases and antioxidases on longevity under nutrient restriction in two Argopecten scallops with distinct lifespans

Nutrient restriction (NR) extends lifespan in many species. High latitudes are characterized by cold-water temperature and food limitations, where bivalves may mimic NR like vertebrates, which could result in a prolonged life expectancy. The long-lived Peruvian scallop (7–10 years) distributes naturally at relatively higher latitudes than the annual bay scallop. However, the relationship and the mechanism underlying the food availability and lifespan are unclear in bivalves. In this study, the genetic response to NR was first investigated in bivalves with distinct lifespans. Peruvian scallops persistently responded to NR mainly via metabolic pathways, but that began to play roles in bay scallops after 56 days. Significant down-regulated expression of long-chain saturated fatty acid synthetase in both two scallops and increased expression of SCD5 and LIPN2 in Peruvian scallops might contribute to MUFA accumulation under NR. SOD1 was more highly expressed in Peruvian scallops than in bay scallops under NR, and strong autophagy was detected only in Peruvian scallops. Peruvian scallops presented much lower MDA levels and higher SOD1 activities than bay scallops. These findings help us understanding the role of lipases and antioxidases in longevity of bivalves, and provide potential biomarkers for breeding long-lived larger scallops.

Utilizing diffusion tensor imaging as an image biomarker in exploring the therapeutic efficacy of forniceal deep brain stimulation in a mice model of Alzheimer’s disease

Objective.With prolonged life expectancy, the incidence of memory deficits, especially in Alzheimer's disease (AD), has increased. Although multiple treatments have been evaluated, no promising treatment has been found to date. Deep brain stimulation (DBS) of the fornix area was explored as a possible treatment because the fornix is intimately connected to memory-related areas that are vulnerable in AD; however, a proper imaging biomarker for assessing the therapeutic efficiency of forniceal DBS in AD has not been established.Approach.This study assessed the efficacy and safety of DBS by estimating the optimal intersection volume between the volume of tissue activated and the fornix. Utilizing a gold-electroplating process, the microelectrode's surface area on the neural probe was increased, enhancing charge transfer performance within potential water window limits. Bilateral fornix implantation was conducted in triple-transgenic AD mice (3 × Tg-AD) and wild-type mice (strain: B6129SF1/J), with forniceal DBS administered exclusively to 3 × Tg-AD mice in the DBS-on group. Behavioral tasks, diffusion tensor imaging (DTI), and immunohistochemistry (IHC) were performed in all mice to assess the therapeutic efficacy of forniceal DBS.Main results.The results illustrated that memory deficits and increased anxiety-like behavior in 3 × Tg-AD mice were rescued by forniceal DBS. Furthermore, forniceal DBS positively altered DTI indices, such as increasing fractional anisotropy (FA) and decreasing mean diffusivity (MD), together with reducing microglial cell and astrocyte counts, suggesting a potential causal relationship between revised FA/MD and reduced cell counts in the anterior cingulate cortex, hippocampus, fornix, amygdala, and entorhinal cortex of 3 × Tg-AD mice following forniceal DBS.Significance.The efficacy of forniceal DBS in AD can be indicated by alterations in DTI-based biomarkers reflecting the decreased activation of glial cells, suggesting reduced neural inflammation as evidenced by improvements in memory and anxiety-like behavior.

A Cross-sectional Survey of Comorbidity Profile among Adult Human Immunodeficiency Virus-infected Patients Attending a Nigeria Medical University Teaching Hospital Campus Located in Akure, Ondo State

Abstract Background and Aim: Previous studies have shown that comorbid human immunodeficiency virus (HIV)-infected patients have a higher chance of dying from non-HIV comorbid disease conditions than due to HIV infection itself. This study was designed to determine the prevalent comorbid conditions among adult HIV-infected patients attending the antiretroviral clinic at a Nigeria Medical University Teaching Hospital campus in Akure, Ondo state. Materials and Methods: This prospective cross-sectional study was carried out for 6-month duration between October 2021 and April 2022. A structured, interviewer-administered questionnaire was used to collect data from a total of 252 adult HIV-infected patients who have been on a combination antiretroviral therapy (cART) for at least a year. The data obtained were analyzed using the measure of descriptive statistics integrated within the software of the Statistical Package for the Social Sciences (SPSS) version 17. Results: The prevalence of comorbidity and multimorbidity (polypathology) in the present study was 40.1% and 9.5%, respectively. The result revealed that bone diseases (28.17%) and hypertension (9.92%) accounted for the predominant comorbidities observed. Using the revised 11th edition of the International Classification of Diseases (ICD-11) to categorize the associated comorbid disease conditions, ICD Class 15 was the most predominant, followed by ICD Class 11, ICD Class 13, ICD Class 21, ICD Class 5, ICD Class 9, and ICD Class 12. Conclusion: Comorbidities have gradually become prevalent epidemics among people living with HIV infection due to their prolonged life expectancy and increased survival outcome over time with the chronic intake of cART.

Low prevalence of peptic ulcer disease in hospitalized patients with cystic fibrosis: A national database study

BackgroundAlthough cystic fibrosis (CF) is widely considered a lung disease, the prevalence of CF-specific gastrointestinal symptoms and diseases has continued to rise. Peptic ulcer disease (PUD) has not been well-studied among people with CF (PwCF) and may be a common cause of abdominal symptoms. In PwCF, impaired bicarbonate secretion and unbuffered gastric acid production have been attributed to the development of ulcers, although ulcers remain uncommon. The objective of this study was to evaluate the prevalence of PUD in PwCF and assess for possible contributing factors. MethodsThis study utilized the National Inpatient Sample (NIS) database. All patients 18 years or older with CF were identified from 2014 to 2019. Relevant patient characteristics and procedures were identified using ICD-9 and ICD-10 codes. Linear trend, bivariate analyses, and multiple regression analysis were performed. The outcomes of interest were peptic ulcer disease, pancreatic insufficiency, and nonalcoholic steatohepatitis or NASH. All analyses accounted for complex sampling scheme of the NIS. ResultsThe total prevalence of PwCF in the National Inpatient Sample (NIS) database was 0.08 %, and the number was stable year to year from 2014 to 2019. Hispanic patients were more likely to be diagnosed with PUD than other white (aOR 1.802 [1.311,2.476]). Multiple regression analysis indicated that PUD in PwCF was strongly associated with a diagnosis of NASH (aOR 2.421[1.197, 4.898]). PUD patients were less likely to have pancreatic insufficiency compared to the non-PUD group (aOR 0.583 [0.455, 0.745]). ConclusionAlthough cystic fibrosis has been historically known as a disease of childhood, advancements in therapy have led to prolonged life expectancy and higher prevalence for cystic fibrosis-related digestive diseases. This study revealed a low prevalence of PUD in PwCF. Hispanics and those with NASH are more likely to develop peptic ulcers.

Non-Invasive Ventilation for Children Affected by Duchenne Muscular Dystrophy in Ukraine

Background: Duchenne Muscular Dystrophy (DMD) poses significant challenges, especially in Low- and Middle-Income Countries (LMIC) with limited access to Non-Invasive Mechanical Ventilation (NIV), which prolongs life expectancy. Two years after Stage 1 of the successfull “1500 years of survival” NIV programme commenced with 8 DMD boys in Ukraine in 2021, this study further explores the Stage 2 of the programme in 2023. Method: DMD patients underwent a 5-day training program at the National Children’s Clinical Hospital “Okhmatdyt” in Kyiv, Ukraine, utilizing donated second-hand bilevel intermittent positive presure ventilators. Indications for NIV included: sleep-related symptoms, high Apnea-Hypopnea Index (AHI&gt;10 events/hour), decreased Forced Vital Capacity (FVC=50%), low minimum saturation during sleep (SpO2&lt;88%), or age above 17 years. Parallel Masterclass on NIV was conducted for Ukrainian healthcare professionals and patients’ parents. Findings: Thirteen DMD inpatients, aged (mean ± standard deviation) 14.8±2.6 years and FVC of 1.8±0.4L (65.5±22.8% predicted value) were enrolled. Criteria for NIV initiation were: age&gt;17 years (n: 4), FVC% =50% (n :6), AHI&gt;10 (n :2) and SpO2&lt;88% (n :5). Follow-up phone calls were conducted to monitor progress. Three months post-hospitalization, all 13 patients consistently adhered to nocturnal ventilator treatment with a mean use of 7.5 hours per night. Conclusions: Despite the lack of equipment and system of reimbursement, the implementation of the comprehensive Stage 2 training programme supplying NIV for DMD patients in an LMIC such as in Ukraine, was a successful experience. The next steps in the home NIV programme will take place in the coming years.

Living longer and stronger: Are children and young adults with Down syndrome experiencing healthier and better lives?

Down syndrome (DS) is the most common genetic cause of intellectual disability and is associated with multiple medical conditions affecting various organ systems, impacting the individual’s health, development and function.1 In Singapore, the life-birth prevalence of DS was 0.89 per 1000 births in the 1990s, a figure expected to decline further due to improved antenatal testing methods, despite the increasing trend in maternal age.2 Advances in medical technology, including surgery for complex congenital heart disease, have extended the life expectancy of individuals with DS to around 60 years.3 Although global life expectancy and disability-adjusted life years for individuals with DS have remained largely stable, the overall disease burden has increased due to longer years lived with disability. From 2010 to 2019, the estimated annual percentage increase in years lived with disability was 1.07 years.4 Therefore, it is essential for service providers to shift their focus from merely prolonging life expectancy to improving the quality of life (QOL) for individuals with DS, which is the focus of the study by Chan et al. published in this issue of the Annals.5

Timing of SMN replacement therapies in mouse models of spinal muscular atrophy: a systematic review and meta-analysis.

Mutations in the Survival of Motor Neuron 1 gene lead to a loss of survival motor neuron protein in patients with spinal muscular atrophy. Revolutionary advances in gene therapy have led to survival motor neuron-replacement therapies that significantly prolong life expectancy and improve neuromuscular function. However, accumulating evidence suggests that the timing of survival motor neuron-replacement therapies is a critical determinant of success. We performed a systematic review and meta-analysis of all pre-clinical studies testing survival motor neuron replacement therapies in mouse models of spinal muscular atrophy to assess the impact of timing of delivery on therapeutic effectiveness. We incorporated four databases in this pre-registered study (PROSPERO 2020 CRD42020200180): EMBASE, PubMed, Scopus and Web of Science. Inclusion criteria were; primary research article, a measure of survival analysis, use of survival motor neuron mouse model and evaluation of survival motor neuron-targeting therapy. Exclusion criteria included; use of therapies not known to directly target survival motor neuron, genetic manipulations and/or lack of appropriate controls. We screened papers using the SyRF platform. The main outcome we assessed was survival in treated groups compared to untreated groups. We performed meta-analysis of survival using median survival ratio and the random effects model and measured heterogeneity using the I 2 statistic. Subgroup analyses were performed to assess treatment efficacy based on timing of intervention (embryonic delivery, day of birth, postnatal day 2 and postnatal day 3 or later) and treatment type. If detailed in the studies, body weight compared to untreated spinal muscular atrophy models and motor neuron number were included as secondary outcomes for meta-analysis. 3469 studies were initially identified, with 78 ultimately included. Survival motor neuron-replacement therapies significantly affected survival in favour of treatment by a factor of 1.20 (95% CI 1.10-1.30, P < 0.001) with high heterogeneity (I 2 = 95%). Timing of treatment was a significant source of heterogeneity (P < 0.01), with earlier treatment having a greater impact on survival. When stratified by type of treatment, earlier treatment continued to have the strongest effect with viral vector replacement therapy and antisense oligonucleotide therapy. Secondary outcome measures of body weight and spinal motor neuron counts were also positively associated with early treatment. Earlier delivery of survival motor neuron replacement therapies is therefore a key determinant of treatment efficacy in spinal muscular atrophy.

The impact of widowhood on the quality of life of older adults: the mediating role of intergenerational support from children

BackgroundChina’s transition into an aging society is accelerated by the simultaneous decline in fertility rates and the prolonged life expectancy of older adults. The impact of widowhood, a significant stressor in old age, has emerged as a crucial factor affecting the quality of life among the elderly.MethodsThis study is based on data from the 2018 China Health and Aging Tracking Survey. Multiple linear regression models were employed to investigate the influence of widowhood on the quality of life of older adults in China. Additionally, Bootstrap mediation effects were utilized to assess the mediating role of intergenerational support, considering both financial and emotional support from children.ResultsThe findings indicate a substantial reduction in the quality of life index among older adults following widowhood. Moreover, the impact is more pronounced among older men compared to older women. Rural older adults experience a significant decline in quality of life post-widowhood, while the effect on urban counterparts is not statistically significant.ConclusionsIntergenerational financial support was identified as a partial mediator between widowhood and the quality of life among older adults. This underscores the importance of familial financial assistance in mitigating the adverse effects of widowhood on the well-being of the elderly. These results offer valuable insights into the nuanced impact of widowhood on the quality of life among older adults in China, emphasizing the need for targeted interventions, especially in rural areas.Clinical trialNot applicable.

Position paper on essential strategies for healthy aging: focus on preventing sarcopenia and cardiovascular diseases from the 38&lt;sup&gt;th&lt;/sup&gt; National Congress of the Italian Society of Geriatrics Hospital and Territory (SIGOT)

Italy’s demographic setting is rapidly evolving and is characterized by a substantial increase in the older population segment. This trend, driven by prolonged life expectancy and declining birth rates, positions Italy as a leader in global aging patterns. The 38th National Congress of the Società Italiana di Geriatria Ospedale e Territorio (SIGOT), held in Rome, underlined the importance of addressing the health needs of this aging population, particularly focusing on preventing sarcopenia and cardiovascular diseases. Recent data challenge the notion of functional decline as an inevitable consequence of aging, highlighting the interplay of genetic, environmental, and lifestyle factors in modulating health outcomes. Sarcopenia, a prevalent condition and biological substrate of frailty, significantly impacts physical function and mortality rates, necessitating behavioral interventions to mitigate its effects. Physical exercise emerges as a key strategy for maintaining cardiovascular health and reducing the risk of arrhythmias, prevalent in older age groups. However, the complex relationship between physical activity intensity, age, and cardiovascular risk underlines the importance of tailored interventions and preliminary screenings. Looking ahead, proactive measures such as enhanced screening, promoting lifelong healthy habits, research and innovation, robust community support systems, and adaptable policies are essential to address the multifaceted challenges posed by an aging population. With this consensus paper, we aimed to summarize the key messages from the three intensive days of the SIGOT National Congress.

The Role of Oxidative Stress in Hypertension: The Insight into Antihypertensive Properties of Vitamins A, C and E.

Hypertension stands as a pervasive global health challenge, contributing significantly to mortality rates worldwide. Various factors, including lifestyle choices and dietary habits, contribute to the development of hypertension. In recent years, oxidative stress has garnered significant attention as a factor influencing hypertension risk, prompting a shift in research focus towards exploring it as a potential target for prevention and treatment. Antioxidants found in our diet, such as vitamins C, E and carotenoids exhibit the ability to neutralize reactive oxygen species, thereby mitigating oxidative stress. In addition, Vitamin A has an antioxidant effect despite not being an antioxidant itself. Consequently, supplementation or increased intake of these antioxidants has been hypothesized to potentially lower blood pressure levels and aid in the management of hypertension, thereby potentially prolonging life expectancy. Research findings regarding this effect have been diverse. This paper examines the existing literature demonstrating favorable outcomes associated with antioxidant supplementation.

Recent Vaccines against Emerging and Tropical Infectious diseases

Emerging diseases, re-emerging diseases and tropical diseases are a slowly progressing problem globally. This may in part be the result of shifting population, growing poverty, inadequate distribution of resources, or even complacency against personal hygiene. As a result of the low income and low standards of health in developing countries, they provide the perfect breeding grounds for the pathogens and parasites that are the root cause of Neglected Tropical diseases (NTDs). In the case of emerging diseases, most are of zoonotic origin and the recent COVID-19 pandemic is a key example. However, it is not just new diseases but re-emerging diseases such as Influenza that highlight the relentless nature of these infections. Vaccines represent the ultimate safety net against these diseases by bolstering immune systems and lowering subsequent mortality and morbidity of these conditions. In fact, against diseases with high mortalities such as AIDS, Hepatitis, and Malaria, vaccine development has markedly reduced mortality and prolonged life expectancy of those afflicted with these conditions. However, this research highlights the importance of enhancing vaccine efficacy and response. The review further underscores the necessity of research, the timing of vaccine administration, effective resource management by governments, and the perception of the population. Therefore, the review offers valuable insights for the medical community and the pharmaceutical industry in improving research and management to maximize the potential of vaccines.
