Global Public Health Problem

Foodborne safety has become a global public health problem in both developed and developing countries. The rapid and precise monitoring and detection of foodborne pathogens has generated a strong interest by researchers in order to control and prevent human foodborne infections. Traditional methods for the detection of foodborne pathogens are often time-consuming, laborious, expensive, and unable to satisfy the demands of rapid food testing. Owing to the advantages of simplicity, real-time analysis, high sensitivity, miniaturization, rapid detection time, and low cost, electrochemical biosensing technology is more and more widely used in determination of foodborne pathogens. Here, we summarize recent developments in electrochemical biosensing technologies used to detect common foodborne pathogens. Additionally, we discuss research challenges and future prospects for this field of study.

The multifaceted key roles of cytokines in immunity and inflammatory processes have led to a high clinical interest for the determination of these biomolecules to be used as a tool in the diagnosis, prognosis, monitoring and treatment of several diseases of great current relevance (autoimmune, neurodegenerative, cardiac, viral and cancer diseases, hypercholesterolemia and diabetes). Therefore, the rapid and accurate determination of cytokine biomarkers in body fluids, cells and tissues has attracted considerable attention. However, many currently available techniques used for this purpose, although sensitive and selective, require expensive equipment and advanced human skills and do not meet the demands of today’s clinic in terms of test time, simplicity and point-of-care applicability. In the course of ongoing pursuit of new analytical methodologies, electrochemical biosensing is steadily gaining ground as a strategy suitable to develop simple, low-cost methods, with the ability for multiplexed and multiomics determinations in a short time and requiring a small amount of sample. This review article puts forward electrochemical biosensing methods reported in the last five years for the determination of cytokines, summarizes recent developments and trends through a comprehensive discussion of selected strategies, and highlights the challenges to solve in this field. Considering the key role demonstrated in the last years by different materials (with nano or micrometric size and with or without magnetic properties), in the design of analytical performance-enhanced electrochemical biosensing strategies, special attention is paid to the methods exploiting these approaches.

Global Public Health Problem

This literature review discusses the most frequently used serodiagnostic methods for the determination of the humoral immune response to malarial parasites. The importance of malaria as a global public health problem is stressed in the light of the new discoveries leading to the future development of an anti-malarial vaccine suitable for use in humans. Serological techniques are expected to play an important role in the assessment of the relative efficacy of these candidate vaccines. A discussion of the different antigen preparation techniques is also presented.

With the development of nanomaterials and sensor technology, nanomaterials-based electrochemical immunosensors have been widely employed in various fields. Nanomaterials for electrode modification are emerging one after another in order to improve the performance of electrochemical immunosensors. When compared with traditional detection methods, electrochemical immunosensors have the advantages of simplicity, real-time analysis, high sensitivity, miniaturization, rapid detection time, and low cost. Here, we summarize recent developments in electrochemical immunosensors based on nanomaterials, including carbon nanomaterials, metal nanomaterials, and quantum dots. Additionally, we discuss research challenges and future prospects for this field of study.

Nowadays, tuberculosis (TB) is an important global public health problem, being responsible for millions of TB-related deaths worldwide. Due to the increased number of cases and resistance of Mycobacterium tuberculosis to all drugs used for the treatment of this disease, we desperately need new drugs and strategies that could reduce treatment time with fewer side effects, reduced cost and highly active drugs against resistant strains and latent disease. Considering that, 4H-1,3-benzothiazin-4-one is a promising class of antimycobacterial agents in special against TB-resistant strains being the aim of this review the discussion of different aspects of this chemical class such as synthesis, mechanism of action, medicinal chemistry and combination with other drugs.

Heart failure (HF) is a major global public health problem irrespective of its causes. It generates an enormous clinical, societal, and economic, health loss burden with an increase in its prevalence reaching an epidemic proportion. The morbidity and mortality associated with heart failure are increasing the health-related burdens worldwide, especially in low- and middle-income countries. This review highlights the trends in HF burden, the clinical spectrum of HF, and the importance of neurohormonal pathways and the evolution of angiotensin receptor neprilysin inhibition in HF with updated clinical practice guidelines.

Global Public Health Problem

Medication error is a major cause of morbidity and mortality in medical profession . There is an increasing recognition that medication errors are causing a substantial global public health problem, as many result in harm to patients and increased costs to health providers.Anaesthesia is now safe and routine, yet anaesthetists are not immune from making medication errors and the consequences of their mistakes may be more serious than those of doctors in other specialties. Steps are being taken to determine the extent of the problem of medication error in anaesthesia. In this review, incidence, types, risk factors and preventive measures of the medication errors are discussed in detail.Journal of Bangladesh Society of Anaesthesiologists 2014; 27(1): 31-35

Global Public Health Problem

  El embarazo en adolescentes es un problema de salud pública mundial que altera la salud física, emocional, la condición educativa y económica de los futuros padres; asimismo, frecuentemente se afecta también al producto de la gestación. La investigación fue de tipo retrospectiva, correlacional y cuantitativa. La muestra fue 461 embarazadas adolescentes atendidas en el Hospital “Verdi Cevallos Balda” de la ciudad de Portoviejo durante el 2016. Los resultados de este estudio mostraron que la mayor tasa de embarazo en adolescentes se produjo en primigestas (88,72 %) de 18 años. La desproporción céfalo-pélvica fue el factor materno-fetal que ocupó el primer lugar como causa de cesárea, seguida de factores fetales como distocia de presentación y ruptura prematura de membranas.   Palabras clave: Parto espontáneo, cesárea, pretérmino, postérmino, embarazo.   Abstract Teenage pregnancy is a global public health problem that alters the physical, emotional, educational and economic condition of future parents; likewise, the gestation product is frequently affected. The research was retrospective, correlational and quantitative. The sample was 461 adolescent pregnant women treated at the Hospital "Verdi Cevallos Balda" of the city of Portoviejo during 2016. The results of this study showed that the highest rate of adolescent pregnancy occurred in first-time pregnant women (88.72 %) of 18 years. Cephalopelvic disproportion was the maternal-fetal factor that ranked first as a cause of caesarean section, followed by fetal factors such as presenting dystocia and premature rupture of membranes.   Keywords: Spontaneous delivery, cesarean section, preterm, postterm, pregnancy.

COVID-19 infection increases the risk of death in patients with chronic conditions such as diabetes or obesity. The exact role of vitamin D in COVID-19 infection is unknown and controversial. Furthermore, the exact prevalence of vitamin D deficiency is still unknown but it affects individuals worldwide regardless of ethnicity and age. Herein, we give an overview of vitamin D deficiency as a global public health problem, the role of vitamin D in COVID-19 infection, and the proper approach to treating vitamin D deficiency.
