Polyvascular Disease: A Narrative Review of Risk Factors, Clinical Outcomes and Treatment.

Polyvascular disease has a significant global burden and is associated with increased risk of major adverse cardiac events with each additional vascular territory involved. The purpose of this review is to highlight the risk factors, associated outcomes, emerging genetic markers, and evidence for screening and treatment of polyvascular disease. Polyvascular disease is the presence of atherosclerosis in two or more vascular beds. It has a significant global burden, with a prevalence of 30-70% in patients with known atherosclerosis. Patients with polyvascular disease experience elevated rates of cardiovascular death, myocardial infarction and stroke, especially among high-risk subgroups like those with type 2 diabetes mellitus and there is a step-wise increased risk of adverse outcomes with each additional vascular territory involved. Genetic analyses demonstrate that some individuals may carry a genetic predisposition, while others exhibit higher levels of atherogenic lipoproteins and inflammatory markers. Routine screening for asymptomatic disease is not currently recommended by major cardiovascular societies unless patients are high-risk. While there are no established protocols for escalating treatment, existing guidelines advocate for lipid-lowering therapy. Additionally, recent studies have demonstrated benefit from antithrombotic agents, such as P2Y12 inhibitors and low-dose anticoagulation, but the optimal timing and dosage of these agents has not been established, and the ischemic benefit must be balanced against the increased risk of bleeding in the polyvascular population. Due to the high prevalence and risks associated with polyvascular disease, early identification and treatment intensification are crucial to reduce disease progression. Future research is needed to develop screening protocols and determine the optimal timing and dosing of therapy to prevent ischemic events.

Transcatheter Mitral Valve Repair With the MitraClip Device for Prior Mitral Valve Repair Failure: Insights From the GIOTTO-FAILS Study.

Minimally invasive mitral valve repair has a favorable risk-benefit profile in patients with significant de novo mitral regurgitation. Its role in patients with prior mitral valve repair is uncertain. We aimed to appraise the outcome of patients undergoing transcatheter edge-to-edge repair (TEER) with prior transcatheter or surgical mitral valve repair (SMVR). We queried the Italian multicenter registry on TEER with MitraClip, distinguishing naïve patients from those with prior TEER or (SMVR). Inhospital and long-term clinical/echocardiographic outcomes were appraised. The primary outcome was the occurrence of death or rehospitalization for heart failure. A total of 2238 patients were included, with 2169 (96.9%) who were naïve to any mitral intervention, 29 (1.3%) with prior TEER, and 40 (1.8%) with prior SMVR. Several significant differences were found in baseline clinical and imaging features. Respectively, device success was obtained in 2120 (97.7%), 28 (96.6%), and 38 (95.0%, P=0.261) patients; procedural success in 2080 (95.9%), 25 (86.2%), and 38 (95.0%; P=0.047); and inhospital death in 61 (2.8%), 1 (3.5%), and no (P=0.558) patients. Clinical follow-up after a mean of 14 months showed similar rates of death, cardiac death, rehospitalization, rehospitalization for heart failure, and their composite (all P>0.05). Propensity score-adjusted analysis confirmed unadjusted analysis, with lower procedural success for the prior TEER group (odds ratio, 0.28 [95% CI, 0.09-0.81]; P=0.019) but similar odds ratios and hazard ratios for all other outcomes in the naïve, TEER, and SMVR groups (all P>0.05). In carefully selected patients, TEER can be performed using the MitraClip device even after prior TEER or SMVR.

Modelling the impact of wastewater flows and management practices on antimicrobial resistance in dairy farms

Dairy slurry is a major source of environmental contamination with antimicrobial resistant genes and bacteria. We developed mathematical models and conducted on-farm research to explore the impact of wastewater flows and management practices on antimicrobial resistance (AMR) in slurry. Temporal fluctuations in cephalosporin-resistant Escherichia coli were observed and attributed to farm activities, specifically the disposal of spent copper and zinc footbath into the slurry system. Our model revealed that resistance should be more frequently observed with relevant determinants encoded chromosomally rather than on plasmids, which was supported by reanalysis of sequenced genomes from the farm. Additionally, lower resistance levels were predicted in conditions with lower growth and higher death rates. The use of muck heap effluent for washing dirty channels did not explain the fluctuations in cephalosporin resistance. These results highlight farm-specific opportunities to reduce AMR pollution, beyond antibiotic use reduction, including careful disposal or recycling of waste antimicrobial metals.

A joinpoint analysis examining trends in firearm injuries at six us trauma centers from 2016 to 2022

BackgroundThere is an epidemic of firearm injuries in the United States since the mid-2000s. Thus, we sought to examine whether hospitalization from firearm injuries have increased over time, and to examine temporal changes in patient demographics, firearm injury intent, and injury severity.MethodsThis was a multicenter, retrospective, observational cohort study of patients hospitalized with a traumatic injury to six US level I trauma centers between 1/1/2016 and 6/30/2022. ICD-10-CM cause codes were used to identify and describe firearm injuries. Temporal trends were compared for demographics (age, sex, race, insured status), intent (assault, unintentional, self-harm, legal intervention, and undetermined), and severity (death, ICU admission, severe injury (injury severity score ≥ 16), receipt of blood transfusion, mechanical ventilation, and hospital and ICU LOS (days). Temporal trends were examined over 13 six-month intervals (H1, January–June; H2, July–December) using joinpoint regression and reported as semi-annual percent change (SPC); significance was p < 0.05.ResultsFirearm injuries accounted for 2.6% (1908 of 72,474) of trauma hospitalizations. The rate of firearm injuries initially declined from 2016-H1 to 2018-H2 (SPC = − 4.0%, p = 0.002), followed by increased rates from 2018-H2 to 2020-H1 (SPC = 9.0%, p = 0.005), before stabilizing from 2020-H1 to 2022-H1 (0.5%, p = 0.73). NH black patients had the greatest hospitalization rate from firearm injuries (14.0%) and were the only group to demonstrate a temporal increase (SPC = 6.3%, p < 0.001). The proportion of uninsured patients increased (SPC = 2.3%, p = 0.02) but there were no temporal changes by age or sex. ICU admission rates declined (SPC = − 2.2%, p < 0.001), but ICU LOS increased (SPC = 2.8%, p = 0.04). There were no significant changes over time in rates of death (SPC = 0.3%), severe injury (SPC = 1.6%), blood transfusion (SPC = 0.6%), and mechanical ventilation (SPC = 0.6%). When examined by intent, self-harm injuries declined over time (SPC = − 4.1%, p < 0.001), assaults declined through 2019-H2 (SPC = − 5.6%, p = 0.01) before increasing through 2022-H1 (SPC = 6.5%, p = 0.01), while undetermined injuries increased through 2019-H1 (SPC = 24.1%, p = 0.01) then stabilized (SPC = − 4.5%, p = 0.39); there were no temporal changes in unintentional injuries or legal intervention.ConclusionsHospitalizations from firearm injuries are increasing following a period of declines, driven by increases among NH Black patients. Trauma systems need to consider these changing trends to best address the needs of the injured population.

Simulation training on respectful emergency obstetric and neonatal care in north-western Madagascar: a mixed-methods evaluation of an innovative training program

BackgroundThe rates of maternal and neonatal deaths in Madagascar are among the highest in the world. In response to a request for additional training from obstetrical care providers at the Ambanja district hospital in north-eastern Madagascar, a partnership of institutions in Switzerland and Madagascar conducted innovative training on respectful emergency obstetric and newborn care using e-learning and simulation methodologies. The training focused on six topics: pre-eclampsia, physiological childbirth, obstetric maneuvers, postpartum hemorrhage, maternal sepsis, and newborn resuscitation. Cross-cutting themes were interprofessional communication and respectful patient care. Ten experienced trainers participated in an e-training-of-trainers course conducted by the Swiss partners. The newly-trained trainers and Swiss partners then jointly conducted the hybrid remote/in-person training for 11 obstetrical care providers in Ambanja.MethodsA mixed methods evaluation was conducted of the impact of the training on participants’ knowledge and practices. Trainees’ knowledge was tested before, immediately after, and 6 months after the training. Focus group discussions were conducted to elicit participants’ opinions about the training, including the content and pedagogical methods.ResultsTrainees’ knowledge of the six topics was higher at 6 months (with an average of 71% correct answers) compared to before the training (62%), although it was even higher (83%) immediately after the training. During the focus group discussions, participants highlighted their positive impressions of the training, including its impact on their sense of professional effectiveness. They reported that their interprofessional relationships and focus on respectful care had improved. Simulation, which was a new methodology for the participants native to Madagascar, was appreciated for its engaging and active format, and they enjoyed the hybrid delivery of the training. Participants (including the trainers) expressed a desire for follow-up engagement, including additional training, and improved access to more equipment.ConclusionThe evaluation showed improvements in trainees’ knowledge and capacity to provide respectful emergency care to pregnant women and newborns across all training topics. The hybrid simulation-based training method elicited strong enthusiasm. Significant opportunity exists to expand the use of hybrid onsite/remote simulation-based training to improve obstetrical care and health outcomes for women and newborns in Madagascar and elsewhere.

Bio-fabricated zinc oxide nanoparticles mediated by endophytic fungus Aspergillus sp. SA17 with antimicrobial and anticancer activities: in vitro supported by in silico studies

IntroductionIn recent years, the world’s attention has been drawn to antimicrobial resistance (AMR) because to the frightening prospect of growing death rates. Nanomaterials are being investigated due to their potential in a wide range of technical and biological applications.MethodsThe purpose of this study was to biosynthesis zinc oxide nanoparticles (ZnONPs) using Aspergillus sp. SA17 fungal extract, followed by characterization of the produced nanoparticles (NP) using electron microscopy (TEM and SEM), UV-analysis, X-ray diffraction (XRD), and Fourier-transform infrared spectroscopy (FT-IR).Results and DiscussionThe HR-TEM revealed spherical nanoparticles with an average size of 7.2 nm, and XRD validated the crystalline nature and crystal structure features of the generated ZnONPs, while the zeta potential was 18.16 mV, indicating that the particles’ surfaces are positively charged. The FT-IR was also used to identify the biomolecules involved in the synthesis of ZnONPs. The antibacterial and anticancer properties of both the crude fungal extract and its nano-form against several microbial strains and cancer cell lines were also investigated. Inhibition zone diameters against pathogenic bacteria ranged from 3 to 13 mm, while IC50 values against cancer cell lines ranged from 17.65 to 84.55 M. Additionally, 33 compounds, including flavonoids, phenolic acids, coumarins, organic acids, anthraquinones, and lignans, were discovered through chemical profiling of the extract using UPLC-QTOF-MS/MS. Some molecules, such pomiferin and glabrol, may be useful for antibacterial purposes, according to in silico study, while daidzein 4’-sulfate showed promise as an anti-cancer metabolite.

Unravelling the complex interplay: environmental mixtures and breast cancer risk

Background. Globally, breast cancer ranks as the fourth most frequent reason for mortality when it comes to fatalities from cancer. The worrisome increases in rates of occurrence and death observed during the previous thirty years or more can be linked to several factors, such as changes in risk factor profiles, advancements in cancer registration, and the development of more effective detection technology. A strong association exists between the progression of metastasis and the mortality rate in breast cancer, with environmental pollutants seemingly contributing to this phenomenon. This association prompts a significant inquiry into the mechanisms that regulate the formation of metastases due to environmental and chemical contaminants. The impact of pollutants and chemical substances on communication pathways, which are essential for the growth and spread of tumor cells, among the numerous possible risk factors is gaining increasing focus. Material and methods. scientific research on environmental variables and additional factors linked to breast carcinoma was located and reviewed using engines such as the PubMed database, the MEDLINE database the Scopus database, and Google Scholar, among others, with search terms like “Breast Cancer”, “Risk components”, “Chemical exposures”, “Environmental toxic exposure”, “Disease progression”, “Bisphenol-A”, “Heavy metallic materials”, and “Food preparations”. Results. This literature aimed to present a thorough overview of the existing data on the impact of environmental and chemical toxins on breast cancer and as a result, a significant relationship between these toxins and breast cancer and its metastatic potential was discovered in more depth. Conclusion. In conclusion, breast cancer's complexity demands a holistic approach encompassing genetic, environmental, and early detection strategies. advancements in stem cell biology and gene identification enhance our understanding. Yet, dissemination remains a key challenge. Environmental toxins play a significant role, necessitating further epidemiological and molecular investigations to mitigate breast cancer's global impact.

AI DRIVEN BLOOD CELL ANALYSIS FOR MALARIA AND BLOOD CANCER SCREENING

Malaria and blood Cancer is one of the deadliest diseases cross the globe. This is caused by the bite of female Anopheles mosquito that transmits the Plasmodium parasites. Some current malaria detection techniques include manual microscopic examination and RDT. These approaches are vulnerable to human mistakes. Early detection of malaria can help in reducing the death rates across the globe.Deep Learning can emerge as a highly beneficial solution in the diagnosis of disease. This model gives a faster and cheaper method for detecting plasmodium parasites. It Was Designed to Identify Malaria Parasites and Cancerous Cell Presence in Blood Using Images of Blood Samples which got Tested with Giemsa-stain. Convolutional neural networks (CNNs) are then trained on these extracted features to accurately classify blood cell images into disease positive or disease-negative categories. The CNN detects malaria parasites in microscopic images by classifying them into parasitized and healthy cells, enabling the detection of malaria parasites. The proposed model consists of three convolutional layers and fully connected layers each. The neural network presented is a cascade of several convolutional layers having multiple filters present in layers, which yields the exceptionally good accuracy as per the available resources. The experiment results demonstrate a significant improvement in malaria parasite and blood cancer recognition. Compared to traditional manual microscopy, the proposed system is more accurate and faster. Finally, this study demonstrates the need to provide robust and efficient solutions by leveraging state-of-the-art technologies to combat malaria and blood cancer.

New York Heart Association functional class and implantable cardioverter-defibrillator in non-ischaemic heart failure with reduced ejection fraction: Extended follow-up of the DANISH trial.

Current guidelines recommend implantable cardioverter-defibrillator (ICD) therapy in patients with heart failure, a left ventricular ejection fraction of ≤35%, and New York Heart Association (NYHA) class II-III. However, the evidence regarding the benefit of primary prevention ICD is less consistent in patients with NYHA class III. We investigated the long-term effects of primary prevention ICD implantation according to NYHA class in an extended follow-up study of the DANISH trial. The DANISH trial randomized 1116 patients with non-ischaemic heart failure with reduced ejection fraction (HFrEF) to ICD implantation or usual care. Outcomes were analysed according to NYHA class at baseline (NYHA class II and III/IV). The primary outcome was all-cause mortality. Of the 1116 patients randomized in the DANISH trial, 597 (53.5%) were in NYHA class II at baseline, 505 (45.3%) in NYHA class III, and 14 (1.3%) in NYHA class IV. During a median follow-up of 9.5 years, NYHA class III/IV, compared with NYHA class II, were associated with a greater long-term rate of all-cause mortality (hazard ratio [HR] 1.52, 95% confidence interval [CI] 1.20-1.93) and cardiovascular death (HR 1.95 [1.47-2.60]). ICD implantation, compared with usual care, did not reduce the long-term rate of all-cause mortality (all participants: HR 0.89 [95% CI 0.74-1.08]; NYHA class II: HR 0.85 [0.64-1.13]; NYHA class III/IV: HR 0.89 [0.69-1.14]; pinteraction = 0.78) or cardiovascular death (all participants: HR 0.87 [95% CI 0.70-1.09]; NYHA class II: HR 0.78 [0.54-1.12]; NYHA class III/IV: HR 0.89 [0.67-1.19]; pinteraction = 0.58), irrespective of NYHA class. Similarly, NYHA class did not modify the beneficial effects of ICD implantation on sudden cardiovascular death (all participants: HR 0.60 [95% CI 0.40-0.92]; NYHA class II: HR 0.73 [0.40-1.36]; NYHA class III/IV: HR 0.52 [0.29-0.94]; pinteraction = 0.39). In patients with non-ischaemic HFrEF, ICD implantation, compared with usual care, did not reduce the overall mortality rate, but it did reduce sudden cardiovascular death, regardless of baseline NYHA class.

Efficacy and Safety of Bufei Jiedu Granules in Treating Multidrug-Resistant Pulmonary Tuberculosis: A Multi-center, Double-Blinded and Randomized Controlled Trial.

To assess the efficacy and safety of Bufei Jiedu (BFJD) ranules as adjuvant therapy for patients with multidrug-resistant pulmonary tuberculosis (MDR-PTB). A large-scale, multi-center, double-blinded, and randomized controlled trial was conducted in 18 sentinel hospitals in China from December 2012 to December 2016. A total of 312 MDR-PTB patients were randomly assigned to BFJD Granules or placebo groups (1:1) using a stratified randomization method, which both received the long-course chemotherapy regimen for 18 months (6 Am-Lfx-P-Z-Pto, 12 Lfx-P-Z-Pto). Meanwhile, patients in both groups also received BFJD Granules or placebo twice a day for a total of 18 months, respectively. The primary outcome was cure rate. The secondary outcomes included time to sputum-culture conversion, changes in lung cavities and quality of life (QoL) of patients. Adverse reactions were monitored during and after the trial. A total of 216 cases completed the trial, 111 in the BFJD Granules group and 105 in the placebo group. BFJD Granules, as an adjuvant treatment, increased the cure rate by 13.6% at the end of treatment, compared with the placebo (58.4% vs. 44.8%, P=0.02), and accelerated the median time to sputum-culture conversion (5 months vs. 11 months). The cavity closure rate of the BFJD Granules group (50.6%, 43/85) was higher than that of the placebo group (32.1%, 26/81; P=0.02) in patients who completed the treatment. At the end of the intensive treatment, according to the 36-item Short Form, the BFJD Granules significantly improved physical functioning, general health, and vitality of patients relative to the placebo group (all P<0.01). Overall, the death rates in the two groups were not significantly different; 5.1% (8/156) in the BFJD Granules group and 2.6% (4/156) in the placebo group. Supplementing BFJD Granules with the long-course chemotherapy regimen significantly increased the cure rate and cavity closure rates, and rapidly improved QoL of patients with MDR-PTB (Registration No. ChiCTR-TRC-12002850).

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

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

Trends in the survival of patients with trisomy 13 from 1995 to 2021: A population study in Japan.

It remains unclear whether recent changes in the prognosis and management of patients with trisomy 13 impact patient survival. We investigated changes in survival of patients with trisomy 13 in Japan. Data from the Vital Statistics Database in Japan was retrieved to examine the association of sex, surgical history, and years of birth and death with changes in survival patterns in 1164 patients with trisomy 13 between 1995 and 2021. The rates of deaths due to trisomy 13 increased from 9.8% to 23.1% in those over 1 year of age and from 7.3% to 19.2% in those within 24 h of birth between 1995 and 2021. The median survival time was longer in 2009-2021 than in 1996-2008 (40 vs. 84 days, p < 0.001). The median survival time and the rate of patients with surgical history increased from 91 days and 16.0% in 1996-2008 to 179 days and 28.0% in 2009-2021, respectively. Median survival time among patients with trisomy 13 has increased over the last 26 years, with almost 1 in 3 patients currently surviving for more than 1 year. The increased surgical intervention rate might have contributed to this improvement.

ASSESSMENT OF TREATMENT OUTCOMES AND SOME RISK FACTORS FOR MORTALITY OF COMMUNITY-ACQUIRED PNEUMONIA CAUSED BY STAPHYLOCOCCUS AUREUS IN THE ELDERLY POPULATION

Objectives: Community-acquired pneumonia is a notable contributor to mortality from infectious diseases on a worldwide scale, especially in the older population. Staphylococcus aureus is a prevalent infection known to cause severe pneumonia, often leading to a high incidence of complications and fatality. The study's objective was to assess the treatment outcomes and some factors associated with mortality rates of Staphylococcus aureus pneumonia in older people. Subjects and method: A cross-sectional study was conducted with 93 patients diagnosed with Staphylococcus aureus pneumonia admitted to Can Tho Central General Hospital from April 2021 to May 2023. Results: The research results showed clinical outcomes including 30-day all-cause death rates and pneumonia-related complications were slightly higher in the age group over 60 compared to those aged 60 and under, but the difference was not statistically significant. After performing multivariate analysis, it was found that heart failure (OR = 5.68, 95% CI: 1.01-32.1, p = 0.049) and central nervous system disease (OR = 5.26, 95% CI: 1.32-20.9, p = 0.018) were found to be independent factors that increased the mortality rate in individuals aged over 60. Conclusion: Clinical practitioners should evaluate and manage comorbidities regarding heart failure and central nervous system diseases during treatment of Staphylococcus aureus pneumonia due to its elevated fatality rate, especially in old patients.

How do we understand the value of drug checking as a component of harm reduction services? A qualitative exploration of client and provider perspectives

BackgroundMortality related to opioid overdose in the U.S. has risen sharply in the past decade. In California, opioid overdose death rates more than tripled from 2018 to 2021, and deaths from synthetic opioids such as fentanyl increased more than seven times in those three years alone. Heightened attention to this crisis has attracted funding and programming opportunities for prevention and harm reduction interventions. Drug checking services offer people who use drugs the opportunity to test the chemical content of their own supply, but are not widely used in North America. We report on qualitative data from providers and clients of harm reduction and drug checking services, to explore how these services are used, experienced, and considered.MethodsWe conducted in-depth semi-structured key informant interviews across two samples of drug checking stakeholders: “clients” (individuals who use drugs and receive harm reduction services) and “providers” (subject matter experts and those providing clinical and harm reduction services to people who use drugs). Provider interviews were conducted via Zoom from June-November, 2022. Client interviews were conducted in person in San Francisco over a one-week period in November 2022. Data were analyzed following the tenets of thematic analysis.ResultsWe found that the value of drug checking includes but extends well beyond overdose prevention. Participants discussed ways that drug checking can fill a regulatory vacuum, serve as a tool of informal market regulation at the community level, and empower public health surveillance systems and clinical response. We present our findings within three key themes: (1) the role of drug checking in overdose prevention; (2) benefits to the overall agency, health, and wellbeing of people who use drugs; and (3) impacts of drug checking services at the community and systems levels.ConclusionThis study contributes to growing evidence of the effectiveness of drug checking services in mitigating risks associated with substance use, including overdose, through enabling people who use and sell drugs to test their own supply. It further contributes to discussions around the utility of drug checking and harm reduction, in order to inform legislation and funding allocation.

Global trends in pharmacovigilance-related events: a 30-year analysis from the 2019 global burden of disease study.

Establishing effective pharmacovigilance systems globally is challenging due to the need for comprehensive epidemiological data on pharmacovigilance-related events, particularly in countries at different stages of development. This study aimed to determine magnitude and drivers of change in the global and regional burden of pharmacovigilance-related events from 1990 to 2019, analyzing variations between age groups and sex, providing data support for policymakers to adjust their pharmacovigilance policies. Pharmacovigilance-related events were defined as Adverse Effects of Medical Treatment (AEMT) and Drug Use Disorders (DUD) in the Global Burden of Diseases, Injuries, and Risk Factors Study 2019. Time trend analysis utilized joinpoint regression, age-period-cohort model, and decomposition method. Disease burden was measured in incidence, deaths, and disability-adjusted life years (DALYs). The global burden of pharmacovigilance-related events remained high, driven predominantly by population growth. Children and older adults were identified as particularly susceptible groups. Across various regions and periods of the socio-demographic index (SDI), the risk of death from AEMT showed a decreasing trend. In contrast, the incidence of AEMT and both the incidence and death rates from DUD showed a stable or worsening trend. Significant regional disparities in the burden of these diseases were noted between different SDI levels. The study underscores the critical need for robust pharmacovigilance systems worldwide. The observed trends in the burden of pharmacovigilance-related events offer a clear direction for countries to refine and strengthen their pharmacovigilance policies and practices.

Extracorporeal life support after surgical repair for acute type a aortic dissection: A systematic review and meta-analysis.

The use of extracorporeal life support (ECLS) in patients after surgical repair for acute type A aortic dissection (ATAAD) has not been well documented. We performed a systematic review and meta-analysis to assess the outcomes of ECLS after surgery for ATAAD with data published by October 2023 in compliance with the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) and the Meta-analysis of Observational Studies in Epidemiology (MOOSE) reporting guidelines. The protocol was registered in PROSPERO (CRD42023479955). Twelve observational studies met our eligibility criteria, including 280 patients. Mean age was 55.0 years and women represented 25.3% of the overall population. Although the mean preoperative left ventricle ejection fraction was 59.8%, 60.8% of patients developed left ventricle failure and 34.0% developed biventricular failure. Coronary involvement and malperfusion were found in 37.1% and 25.6%, respectively. Concomitant coronary bypass surgery was performed in 38.5% of patients. Regarding ECLS, retrograde flow (femoral) was present in 39.9% and central cannulation was present in 35.4%. In-hospital mortality was 62.8% and pooled estimate of successful weaning was 50.8%. Neurological complications, bleeding and renal failure were found in 25.9%, 38.7%, and 65.5%, respectively. ECLS after surgical repair for ATAAD remains associated with high rates of in-hospital death and complications, but it still represents a chance of survival in critical situations. ECLS remains a salvage attempt and surgeons should not try to avoid ECLS at all costs after repairing an ATAAD case.

THE ROLE OF DOCETAXEL AS FIRST-LINE CHEMOTHERAPY ON PSA LEVEL AND QOL IN CRPC PATIENTS

Objective: Prostate cancer is the second most common cancer in men and the fifth leading cause of death worldwide. 10-20% of cases can progress to a more aggressive stage called castration-resistant prostate cancer (CRPC) with a higher death rate. Clinical guidelines recommend docetaxel as first-line chemotherapy and evaluated using the PSA test. This study aims to investigate the effect of docetaxel chemotherapy on PSA levels in CRPC. Material &amp; Methods: A retrospective study was conducted from January 2016 until August 2022 according to the medical records database Saiful Anwar Hospital. There were 16 patients who met the inclusion criteria, including male patients with a diagnosis of CRPC who received castration therapy and found an increase in PSA 3 times of nadir or found 2 or more bone metastatic lesions or soft tissue lesions &gt; 2 cm, received 6 series of docetaxel chemotherapy, and have a PSA data was performed before and after chemotherapy. Statistical analysis was performed using a differential T-test. Results: The results, obtained were significantly different (p&lt;0.05) on the average PSA (log) pre-post chemotherapy, visual analog scale (VAS), and quality of life, and not significantly different on BMI pre-post chemotherapy. Conclusion: 6 cycles of docetaxel chemotherapy resulted in a decrease in PSA levels of CRPC significantly. It showed an excellent response to docetaxel chemotherapy in managing CRPC patients. Limitations of this study were specifically the retrospective cohort study model and the ability to reduce PSA levels in assessing the prognosis of CRPC. Keywords: Castration-resistant prostate cancer, chemotherapy, docetaxel, prostate-specific antigen.

A Comparative Study between Time Series and Machine Learning Technique to Predict Dengue Fever in Dhaka City

The dengue virus is the most dangerous one that mosquitoes may spread to people. Despite attempts by the government, dengue outbreaks are becoming increasingly common in Bangladesh. Interventions in public health rely heavily on KAP (knowledge, attitude, and practice) studies. The primary goal of this research is to forecast the occurrence of dengue disease in the city of Dhaka using methods from machine learning and time series analysis and then to compare the models in order to find the one with the lowest MAPE. From January 2016 through July 2021, monthly data were retrieved for this study from WHO and the Directorate General of Health and Services (DGHS). According to the findings of this research, neural networks outperform time series analysis when it comes to making predictions. The best-fitted neural network (NN) model was found in model 04 with 05 hidden layers which produced the minimum error model with the value of error 0.003032557, and the values of RMSE and MAPE are 7.588889e − 06 and 1.15273, respectively, for the prediction of the dengue fever in Dhaka city. In contrast, the original dengue data in the time series analysis is not stationary. Take the difference and run the unit root test by the augmented Dickey–Fuller (ADF) test to make it stationary. The dengue data series is stationary at the first-order difference, as evidenced by the ACF and PACF, which show no noticeable spike in the first-order difference. The ARIMA (6, 1, 1) model with the lowest AIC = −251.8, RMSE = 0.0310797, and MAPE = 15.2892 is the best choice model for predicting the dengue death rate. Therefore, from these two models, the NN model gives better prediction performance with the lowest value of MAPE. So, the neural network gives better prediction performance than time series analysis. The NN model forecasted 12-month death rates of dengue fever that suggest the death rate in dengue fever falling month by month. This study is more innovative than any other research because this research approach is different from any other research approach. The model selection criteria are based on the most effective performance metrics MAPE, indicating the lowest error and better prediction performance. Therefore, from this research, the author suggests machine learning gives better prediction performance than time series analysis for any other prediction performance.

The Scabbard of Excalibur: An Allegory on the Role of an Efficient and Effective Healthcare System under Universal Health Coverage during the Pandemic Response

During the COVID-19 pandemic, while some countries succeeded in reducing their rate of death after SARS-CoV-2 infection via vaccination by the end of 2021, some of them also faced hospital capacity strain, leading to social anxiety about delays in the diagnosis and treatment of patients with other diseases. This essay presents an allegory to explain the situation during the COVID-19 pandemic. Through an allegory and Le Morte d’Arthur (Arthur’s Death), this essay indicates that “the scabbard of Excalibur” that we are looking for is an efficient and effective healthcare system that can diagnose patients who might become severely ill due to COVID-19 and to treat them without hospital capacity strain. In Le Morte d’Arthur, the scabbard of Excalibur was lost, and we have not been able to find any alternatives to end the COVID-19 pandemic. We can choose a future in which “the scabbard of Excalibur” exists, providing a different ending for the next pandemic.

Persistent high mortality rates for Diabetes Mellitus and Hypertension after excluding deaths associated with COVID-19 in Brazil, 2020-2022.

The outbreak of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) posed a significant public health challenge globally, with Brazil being no exception. Excess mortality during this period reached alarming levels. Cardiovascular diseases (CVD), Systemic Hypertension (HTN), and Diabetes Mellitus (DM) were associated with increased mortality. However, the specific impact of DM and HTN on mortality during the pandemic remains poorly understood. This study analyzed mortality data from Brazil's mortality system, covering the period from 2015 to 2022. Data included all causes of death as listed on death certificates, categorized by International Classification of Diseases 10th edition (ICD-10) codes. Population data were obtained from the Brazilian Census. Mortality ratios (MRs) were calculated by comparing death rates in 2020, 2021, and 2022 to the average rates from 2015 to 2019. Adjusted MRs were calculated using Poisson models. Between 2015 and 2022, Brazil recorded a total of 11,423,288 deaths. Death rates remained relatively stable until 2019 but experienced a sharp increase in 2020 and 2021. In 2022, although a decrease was observed, it did not return to pre-pandemic levels. This trend persisted even when analyzing records mentioning DM, HTN, or CVD. Excluding death certificates mentioning COVID-19 codes, the trends still showed increases from 2020 through 2022, though less pronounced. This study highlights the persistent high mortality rates for DM and HTN in Brazil during the years 2020-2022, even after excluding deaths associated with COVID-19. These findings emphasize the need for continued attention to managing and preventing DM and HTN as part of public health strategies, both during and beyond the COVID-19 pandemic. There are complex interactions between these conditions and the pandemic's impact on mortality rates.
