IntroductionCoronavirus disease 2019 (COVID-19) can lead to cardiovascular complications. We aimed to understand the trends in admission for COVID-19 and the incidence of various cardiovascular events.Material and methodsThe 2020 and 2021 National Inpatient Sample (NIS) was studied for cases of COVID-19 between April 2020 and December 2021 in the United States. Linear-by-linear association helped us understand the trends of various events.ResultsThe number of cases of COVID-19 was highest in January 2021 (261,469 patients). The incidence of acute pulmonary embolism rose from 2.08% in April 2020 to 4.82% in November 2021, while deep vein thrombosis cases rose from 1.74% in April 2020 to 2.63% in December 2021. The incidence of cardiac arrest varied, with a maximum of 3.00% in August 2021. Similarly, acute ischemic stroke cases experienced their highest incidence in January 2021 (0.91%). The incidence of myocarditis was highest in April and May 2020 (0.42% each). Peak takotsubo cases were seen between October and December 2021. The highest overall all-cause mortality among COVID-19 cases was seen in April 2020 (16.74%).ConclusionsThroughout the 21 months of our analysis, various trends in COVID-19 cases and incidence of cardiac events were noticed. This could relate to the different variants of COVID-19, their direct and indirect impact on coagulation pathways and the myocardial tissues, and the protective roles of the vaccines.

Implications of AI in land management
Authors: Kiptoch William Ndiema 
Published: April 2024

This study sought to find out implications of Artificial Intelligence (AI) in land management. Artificial Intelligence (AI) offers significant benefits for land development and decision-making, ethical concerns regarding data privacy, bias, and social impact necessitate frameworks to ensure its responsible application. The increasing use of AI models in land management raises ethical concerns about data ownership, privacy, algorithmic bias, environmental impact, and social displacement. Traditional research ethics frameworks may not be sufficient for AI-driven land management practices. This paper examines critical issues arising from data governance, algorithmic transparency, and environmental and social impact assessment. It proposes frameworks that consider established research ethics principles and advocate for community engagement. The paper highlights the potential for AI to contribute to sustainable and equitable land management. However, it also identifies potential negative consequences such as job losses, unequal access to technology, and exacerbation of existing social divides. The paper emphasizes the need for collaboration between researchers, policymakers, communities, and developers to construct ethical frameworks that ensure AI contributes to sustainable land management practices. These frameworks should address data governance, algorithmic transparency, environmental and social impact assessments, and community engagement.
A Prioritised Automatic Switching Algorithm for Load Shedding Using Labview
Authors: Annan John Kojo , Dassah Vitalis 
Published: April 2024

Load shedding is employed at the Ghana Grid Company (GRIDCo) Tarkwa power substation to ensure a balance between power demand and available power. This involves taking off loads from the power transmission network when demand exceeds available power. Such loads are later reintroduced when available power is adequate to supply applied loads. The traditional technique of load shedding employed at the GRIDCo power substation in Tarkwa requires dropping electrical loads based on frequency variations. This may lead to dropping load of entire sections without consideration of essential loads. Research into prioritised load shedding algorithm using semi adaptive load shedding approach can continuously monitor and switch loads at the study area which is a transmission substation located in the Western Region of Ghana. Electrical Transient Analysis Program (ETAP) software version 2019 was used to simulate the single line system of the GRIDCo substation to determine the rate of change of frequency against varying loads. The implementation of the proposed technique was achieved with Laboratory Virtual Instrument Engineering Workbench (LabVIEW) software version 2019. Using typical load shedding data from the GRIDCo Tarkwa power substation, the proposed design was tested and found to be effective in carrying out load shedding.

Published: April 2024

Objectives: Percutaneous intervention to aortoiliac occlusive disease (AIOD) is an approved choice of treatment instead of open surgery. However, despite improvement stent technology, in-stent restenosis (ISR) still remains a potential problem, especially in long-term follow-up of these patients. CHADS2 score is mainly a risk stratification tool for atrial fibrillation; however, it is found to be associated with the severity of atherosclerosis and worse outcome of percutaneous interventions. Thus, we aimed to interrogate the relationship between CHADS2 score and ISR in patients with stent implantation for AIOD.
Methods: This was a retrospective, observational study that included 419 consecutive patients who had successful common iliac artery (CIA) and external iliac artery stent implantation. Post-procedural ISR is evaluated by either ultrasonography or angiography for each patient in the follow-up period. Patients were then divided into two groups ISR (+) and ISR (–). CHADS2 score was calculated for every patient.
Results: ISR was detected in 47 out of 419 patients. Patients who had ISR had smaller stent diameter (8.4±0.9 vs. 7.2±2.8, p=0.005) and longer stent length (80 [59–120] mm vs. 59 [39–100] mm, p<0.001) than those without ISR. CHADS2 score was significantly found increased in patients with ISR than those without ISR (2.04 ± 0.98 vs. 1.45±0.93, p<0.001). Chronic obstructive pulmonary disease (COPD) (hazard ratios [HR]: 2.85, 95% confidence interval [CI]: 1.535–5.293, p=0.001), CHADS2 score (HR: 1.571, 95% CI: 1.186–2.081, p=0.002), and decreased stent diameter (HR: 0.582, 95% CI: 0.366–0.926, p=0.022) were found to be independently associated with ISR.
Conclusion: Our study demonstrated that COPD, CHADS2 score, and stent diameter were associated with ISR for patients who had successful iliac artery stent implantation. According to our study, this simple and applicable scoring system can be used to predict patients at high risk for ISR.

Published: April 2024

Objectives: The SYNergy between percutaneous coronary interventions with TAXUS and Cardiac Surgery (SYNTAX) score is a quantitative scoring system used to evaluate the severity and extent of the disease in patients with coronary artery disease. Hospital Anxiety and Depression Scale (HADS) is a scale that measures the anxiety and depression levels of patients. The relationship between psychosocial stress and atherosclerosis is well known. In this study, we aimed to examine the relationship between SYNTAX score and HADS in patients who performed percutaneous coronary intervention due to acute coronary syndrome (ACS).
Methods: A total of 130 subjects with ACS were included in our study. The SYNTAX score, which was calculated by two independent interventional cardiologists, was divided into three groups: 0–22, low; 23–32, moderate; 33 and above, high. In our study, patients’ anxiety and depression levels were evaluated with HADS 1 month after ACS.
Results: Of the total subjects, 68, 39, and 23 patients were determined in SYNTAX scores of 0–22, 23–32, and >33 groups, respectively. A significant relationship was observed between the high SYNTAX score and the HADS-depression and anxiety scale (p<0.001, p<0.001, respectively). In the correlation analysis found that, a moderate positive correlation between the SYNTAX score and depression level, and a weak positive correlation between the SYNTAX and anxiety level (r=0.642, r=0.538, respectively).
Conclusion: In our study, we found that HADS and SYNTAX scores were significantly correlated in ACS patients who performed percutaneous coronary intervention.

Authors: Genç Serhat Bahadır , Ulus Ahmet Tulga , Paç Mustafa 
Published: April 2024

Objectives: Although the mortality rate of primary ventricular septal defect (VSD) closure surgery has been reduced to <0.5% in many centers, low cardiac output syndrome and multi-organ failure syndrome development in the post-operative period are still the most common causes of mortality and morbidity. The use of biochemical markers in the early period can be used as effective predictors for reducing mortality and morbidity. In this study, the effect of post-operative serum lactate and cardiac troponin I (cTNI) levels on hospital mortality in patients who underwent primary closure of VSD was investigated retrospectively.
Methods: The effect of lactate and cTNI values on hospital mortality in 52 patients who underwent surgical repair for VSD was investigated. Serum lactate levels of all patients in the first 6 h after the operation; on the first post-operative day, cTNI values were examined retrospectively. Serum lactate levels exceeding 3.5 mmol/ lt and cTNI values exceeding 35 ng/mL were determined as the cut-off points.
Results: Serum lactate level and cTNI increase were found to be statistically different in the mortality group (p<0.05). It was shown that increased cTNI was associated with weight, left ventricular end-diastolic diameter, and cardiopulmonary bypass time (p<0.05). Serum lactate levels were 4.1±0.5 mmol/lt in the non-mortality group and 15.3±8.3 mmol/lt in the mortality group, and the difference was statistically significant (p<0.05). Hospital mortality was observed in 6 patients.
Conclusion: In patients undergoing VSD closure surgery, serum lactate levels measured in the first 6 h postoperatively and cTNI levels measured on the first post-operative day are associated with hospital mortality. Concomitant elevations of lactate and cTNI values in patients after VSD closure should suggest to take caution and early supportive treatments to reduce mortality.
The River Runner: a low-cost sensor prototype for continuous dissolved greenhouse gas measurements
Authors: Dalvai Ragnoli Martin , Singer Gabriel 
Published: April 2024

Abstract. Freshwater ecosystems are sources of the two most relevant greenhouse gases (GHGs): CO2 and CH4. Understanding the importance of freshwater ecosystems in the global carbon cycle and their role in global warming trends requires the accurate quantification of gas fluxes from the water phase to the atmosphere. These fluxes depend on the gas exchange velocity and the concentration gradient between the phases, which both cause high spatio-temporal variability in fluxes. On a global scale, the estimation of fluxes is limited by the lack of cheap and accurate methods to measure dissolved gas concentrations. Low-cost sensors, as an alternative to expensive gas analysers, are available; however, to date, the in situ performance of such sensors has been poorly examined. Here, we present an inexpensive data-logging sensor prototype that provides continuous measurements of dissolved CO2 and CH4 in submerged environments. Gas measurements are done in a confined gas space, which is rapidly equilibrated with the water phase through a single-layer polytetrafluoroethylene (PTFE) membrane, by a miniature non-dispersive infrared (NDIR) sensor for CO2 (Sunrise sensor, Senseair, Sweden) and a cheap metal oxide sensor for CH4 (TGS2611-E, Figaro Engineering Inc., Japan). Pressure, temperature and humidity are measured to correct raw sensor readings. For freshwater, the dissolved gas concentration is directly obtained from the measured molar fraction and temperature and pressure readings. In air, we measured the molar fraction of CO2 in a range from 400 to 10 000 ppm and the molar fraction of CH4 in a range from 2 to 50 ppm with an accuracy of ± 58 and ± 3 ppm respectively. We successfully used our prototype to measure diurnal variations in dissolved CO2 in a natural stream. We further calibrated the CH4 sensor for in situ use at concentrations ranging from 0.01 to 0.3 µmol L−1. Underwater, we were able to measure the molar fraction of CH4 in the prototype head with an accuracy of ± 13 ppm in the range from 2 to 172 ppm. The underwater measurement error of CH4 is always higher than for the same concentration range in air, and CH4 is highly overestimated below 10 ppm. At low CH4, humidity was the most important influence on the TGS2611-E sensor output in air, whereas temperature became the predominant factor underwater. We describe the response behaviour of low-cost sensors in submerged environments and report calibration methods to correct for temperature and humidity influence on the sensor signal if used underwater. Furthermore, we provide do-it-yourself instructions to build a sensor for submerged continuous measurements of dissolved CO2 and CH4. Our prototype does not rely on an external power source, and we anticipate that such robust low-cost sensors will be useful for future studies of GHG emissions from freshwater environments.

It is an unhappy truth that regardless of being almost fully preventable through human papillomavirus(HPV) vaccination and screening, cervical cancers remains the fourth most common cancers to have an effect on women. High risk HPV infection (hrHPV) is the number one etiological element for cervical cancer. Upto 70% of instances are via HPV types 16 and 18, with many different hrHPV related to the rest of cases. Modern-day trendy- of- care treatments consist of radiotherapy, chemotherapy, and/ or surgical resection. still, they have got good sized side effects and limited efficacy against advanced disease. there are few treatment choices for recurrent or metastatic cases. Immunotherapy gives new stopgap, as demonstrated with the aid of the current blessing of PD1 blocking antibody for recurrent or metastatic disease. This might be augmented by way of mixture with antigen-specific immunotherapy tactics, comparable as vaccines or adoptive cellular transfer, to enhance the host cell immune response targeting HPV-positive cancer cells. As cervical cancers progresses, it is able to foster an immunosuppressive medium and counteract host anticancer immunity. therefore, procedures to reverse suppressive susceptible surroundings and bolster effector T cellular functioning are probable to enhance the success of comparable cervical cancers immunotherapy. The success of non-specific immunostimulants like imiquimod against genital warts additionally propose the possibility of exercising those immunotherapeutic strategies in cervical cancer prevention to deal with precursor lesions(cervical intraepithelial neoplasia) and affected person hrHPV infections against which the licensed prophylactic HPV vaccines haven't any efficacy. We assessed the progress and demanding situations inside the development of immunotherapeutic processes for the prevention and treatment of cervical cancer.

L'anémie constitue un problème majeur de la santé publique à travers le monde malgré l'amélioration remarquable des conditions de vie. Elle est classée par l'OMS comme l'un des dix problèmes les plus sérieux du monde et sa prévalence est plus élevée en Afrique dans le pays envoi de développement (OMS, 2019). Notre objectif est de décrire les profils épidémiologique et étiologique des cas d'anémies prises en charge dans la Zone de Santé de Lemba. Il s'agit d'une étude rétrospective menée durant 1 an, allant de Janvier 2019 à décembre 2019 et portant sur 797 patients. La prévalence de l’anémie au sein de la Zone de Santé de Lemba est de 38,1%. Le poids moyen suivi de l’écart-type de nos patients est de 57,6±8,6 kg. Les patients appartenant au groupe d’âge de 20-24 ans sont le plus touchés, soit (31%). Le ménage avec 2 à 3 enfants développe plus l’anémie, soit (28%). Les patients habitant le milieu périphérique de la zone de santé souffrent plus de l’anémie que les autres, soit (31%). 68% de patient souffrant de l’anémie ont un niveau d’étude primaire. La survenue d'une anémie chez l'adulte peut représenter un véritable défit diagnostique pour l'interniste et cela parfois dans un contexte d'urgence. Le recours à des examens spécialisés peut s'imposer.
