AbstractMalaria is a complex parasitic disease, caused by Plasmodium spp. More than a century after the discovery of malaria parasites, this disease continues to pose a global public health problem and the pathogenesis of the severe forms of malaria remains incompletely understood. Extracellular vesicles (EVs), including exosomes and microvesicles, have been increasingly researched in the field of malaria in a bid to fill these knowledge gaps. EVs released from Plasmodium-infected red blood cells and other host cells during malaria infection are now believed to play key roles in disease pathogenesis and are suggested as vital components of the biology of Plasmodium spp. Malaria-derived EVs have been identified as potential disease biomarkers and therapeutic tools. In this review, key findings of malaria EV studies over the last 20 years are summarized and critically analysed. Outstanding areas of research into EV biology are identified. Unexplored EV research foci for the future that will contribute to consolidating the potential for EVs as agents in malaria prevention and control are proposed.

Abstract Ligands and receptors of the tumor necrosis factor (TNF) superfamily regulate immune responses and homeostatic functions with potential diagnostic and therapeutic implications. Kidney disease represents a global public health problem, whose prevalence is rising worldwide, due to the aging of the population and the increasing prevalence of diabetes, hypertension, obesity, and immune disorders. In addition, chronic kidney disease is an independent risk factor for the development of cardiovascular disease, which further increases kidney-related morbidity and mortality. Recently, it has been shown that some TNF superfamily members are actively implicated in renal pathophysiology. These members include TNF-related apoptosis-inducing ligand (TRAIL), its decoy receptor osteoprotegerin (OPG), and TNF-like weaker inducer of apoptosis (TWEAK). All of them have shown the ability to activate crucial pathways involved in kidney disease development and progression (e.g. canonical and non-canonical pathways of the transcription factor nuclear factor-kappa B), as well as the ability to regulate cell proliferation, differentiation, apoptosis, necrosis, inflammation, angiogenesis, and fibrosis with double-edged effects depending on the type and stage of kidney injury. Here we will review the actions of TRAIL, OPG, and TWEAK on diabetic and non-diabetic kidney disease, in order to provide insights into their full clinical potential as biomarkers and/or therapeutic options against kidney disease.

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.

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

  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.

AbstractCOVID-19 is the present global public health problem. This respiratory viral infection can manifest atypical presentation including neurological presentations. An important neurological problem in COVID-19 is neurovascular thrombosis. The basic pathogenesis of thrombosis in neurological system is explainable by the basic principle of thrombohemostasis. A hypercoagulability is a possible problem seen in some COVID-19 cases. In this brief review, the authors summarize venous and arterial thrombosis of neurovascular system as a complication of COVID-19. The updated pathophysiology of COVID-associated blood coagulation disorder is discussed. In addition, consideration regarding new COVID-19 vaccine related thrombotic adverse event is also raised.

Pandu Roga is one of the diseases mentioned in Ayurveda characterized by the changes in the skin colour to white (Shweta), yellowish (Peeta), greenish (Harita) etc. which is one of the “Varnopalakshita Roga" i.e., a disease characterized by the change in the colour. The clinical condition of Pandu in Ayurveda can be co-related with Anaemia described in Modern Medical Science, due to the resemblance in the clinical signs and symptoms. In Modern Medicine, Pandu is a pale appearance which may be due to the decreased blood supply to the skin or de- creased visibility of oxyhemoglobin. Anaemia is a major global public health problem and the most prevalent nu- tritional deficiency disorder in the world. This article presents the Ayurvedic concept of Pandu Roga (Anaemia). Keywords: Pandu, Vyadhi, Srotas, Anaemia, Pallor,
