Risk Issue

Background: Depression and hypertension are medical problems both with clearly restricted pharmacotherapies, along with a high prevalence around the world. In fact, an intensive discussion in the field is that a dysregulation of the intracellular Ca2+ homeostasis (e.g. excess of intracellular Ca2+) contributes to the pathogenesis of both hypertension and depression. Furthermore, depression rises the risk of hypertension incidence. Indeed, several data support the concept that depression is an independent risk issue for hypertension. Conclusion: Then, which are the possible cellular mechanisms involved in this link between depression and hypertension? Considering our previous reports about the Ca2+ and cAMP signalling pathways (Ca2+/cAMP signalling), in this review I have discussed the virtual involvement of the Ca2+/cAMP signalling in this link (between depression and hypertension). Then, it is important to consider depression into account during the process of prevention, and treatment, of hypertension.

The Relationship

Limitations on the pharmacotherapy and a high prevalence worldwide are critical issues related to depression and cancer. It has been discussed that a dysregulation of intracellular Ca2+ homeostasis is involved in the pathogenesis of both these diseases. In addition, depression raises the risk of cancer incidence. Consistent data support the concept that depression is an independent risk issue for cancer. However, the cellular mechanisms involved in this link between depression and cancer remain uncertain. Considering our previous reports about Ca2+ and cAMP signalling pathways (Ca2+/cAMP signalling), I herein discussed the putative contribution of Ca2+/cAMP signalling in this link between depression and cancer. Moreover, it is important to take depression into account during the process of prevention and treatment of cancer.

Background: The interactions between Alzheimer´s disease (AD) and major depression can be translated into clinical data showing that depressive patients have had an enhanced risk for developing AD (later in life). The cellular mechanisms involved in these interactions remain under intensive debate in literature. In addition, the role of a Ca2+ homeostasis dysregulation in the pathogenesis of neurodegenerative diseases, like AD, and major depression has been under intensive discussion. Objective: Thus, revealing the interplay between AD and major depression may provide novel insights into the pathogenesis of these diseases. Methods: Publications involving Ca2+ signalling pathways, AD and major depression (alone or combined) were collected by searching multiple databases to find the maximum number of relevant citations (using a search strategy with a high sensitivity for studies of etiology). Results: Ca2+ channel blockers (CCBs), classically prescribed for hypertensive patients, have been demonstrating neuroprotective effects, such as decreasing the incidence of AD in hypertensive patients, including alleviating major depression symptoms. A mechanism under debate is focused on the restoration of the Ca2+ homeostasis. Indeed, previous studies of our own have correlated Ca2+ and cAMP signalling pathways (Ca2+/cAMP signalling) in controlling both the neurotransmitter release and neuronal death. These studies also observed that CCBs can affect Ca2+/cAMP signalling. Conclusion: This review discussed the plausible role of Ca2+/cAMP signalling in the neuroprotective effects of CCBs, including the participation of Ca2+/cAMP signalling in the interactions between major depression and AD. Considering both AD and major depression have become high prevalent medical problems in the world, the comprehension of the interactions between these diseases could improve the drug development.

Malaria, caused by apicomplexan parasite, is an old disease and continues to be a major public health threat in many countries. This article aims to present different aspects of malaria including causes, pathogenesis, prevention, and treatment in an articulate and comprehensive manner. Six Plasmodium species are recognized as the etiology of human malaria, of which Plasmodium falciparum is popular in East and Southern Africa. Malaria is transmitted mainly through Anopheles gambiae and Anopheles funestus, the two most effective malaria vectors in the world. Half of the world’s population is at risk for malaria infection. Globally, the morbidity and mortality rates of malaria have become decreased even though few reports in Ethiopia showed high prevalence of malaria. The malaria parasite has a complex life cycle that takes place both inside the mosquito and human beings. Generally, diagnosis of malaria is classified into clinical and parasitological diagnoses. Lack of clear understanding on the overall biology of Plasmodium has created a challenge in an effort to develop new drugs, vaccines, and preventive methods against malaria. However, three types of vaccines and a lot of novel compounds are under perclinical and clinical studies that are triggered by the occurrence of resistance among commonly used drugs and insecticides. Antiadhesion adjunctive therapies are also under investigation in the laboratory. In addition to previously known targets for diagnostic tool, vaccine and drug discovery scientists from all corner of the world are in search of new targets and chemical entities.

Objective: Asthma is correlated with a higher risk of manifesting other diseases, including hypertension, diabetes, obesity, psychiatric and neurological diseases, and cancer. Therefore, revealing this interplay between asthma and these illnesses may provide novel insights into their pathogenesis. Results: It is highly debated that dysregulation of Ca2+ homeostasis is involved in the pathogenesis of these maladies. Not surprisingly, calcium (Ca2+) channel blockers (CCBs), classically used as antihypertensive medicines, have been demonstrating off-label effects such as alleviating asthma symptoms, in addition to antidiabetic, antiobesity, anticancer and antineurodegenerative effects. Our studies about Ca2+/cAMP signalling may shed some new light on this field. Conclusion: Thus, considering that asthma and associated illnesses such as hypertension, diabetes, obesity, cancer and neurodegenerative diseases have become highly prevalent medical problems in the world, the comprehension of this interplay between asthma and other disorders could improve drug therapy.

The outbreak of COVID-19 due to SARS-CoV-2 originally emerged in Wuhan in December 2019. As of March 22, 2020, the disease spread to 186 countries, with at least 305,275 confirmed cases. Although there has been a decline in the spread of the disease in China, the prevalence of COVID-19 around the world remains serious despite containment efforts undertaken by national authorities and the international community. In this article, we systematically review the brief history of COVID-19 and its epidemic and clinical characteristics, highlighting the strategies used to control and prevent the disease in China, which may help other countries respond to the outbreak. This pandemic emphasizes the need to be constantly alert to shifts in both the global dynamics and the contexts of individual countries, making sure that all are aware of which approaches are successful for the prevention, containment and treatment of new diseases, and being flexible enough to adapt the responses accordingly.

Introduction: Diabetes mellitus is a metabolic disease characterized by high glycemic levels for long periods. This disease has a high prevalence in the world population, being currently observed an increase in its incidence. This fact is mainly due to the sedentary lifestyle and hypercaloric diets. Non-pharmacological interventions for glycemic control include exercise, which promotes changes in skeletal muscle and adipocytes. Thus, increased glucose uptake by skeletal muscle and decreased insulin resistance through modulating adipocytes are the main factors that improve glycemic control against diabetes. Conclusion: It was sought to elucidate mechanisms involved in the improvement of glycemic control in diabetics in front of the exercise.

Prevention And Treatment

Cervical cancer (CC) is the second leading cause of cancer death in women aged 20–39 years. Persistent infection with oncogenic types of human papillomavirus (HPV) represents the most important risk factor for the development of cervical cancer. Three HPVs vaccines are currently on the global market: bivalent, quadrivalent, and nonavalent. The nonavalent vaccine provides protection against almost 90% of HPV-related CC. Despite availability of primary and secondary prevention measures, CC persists as one of the most common cancers among women around the world. Although CC is a largely preventable disease, management of persistent or recurrent CC no longer amenable to control with surgery or radiation therapy has not improved significantly with the progress of modern chemotherapy and disseminated carcinoma of the cervix remains a discouraging clinical entity with a 1-year survival rate between 10% and 15%. Over the last few years, there has been increasing interest in immunotherapy as a strategy to fight tumors. This article focuses on recent discoveries about the HPV vaccine and immunotherapies in the prevention and treatment of CC, highlighting the future view.

AbstractInfanticide, like most other species of homicide, is probably coeval with the human race itself. In modern Western civilization, what were formerly the most powerful incentives to infanticide have virtually disappeared. As with other social problems that affluence has seemed to solve, however, infanticide has reappeared in a new form that seems to have been made possible by affluence itself. This "new infanticide" occurs in a place whose very existence is the result of a tremendously wealthy society's devotion to its most vulnerable and least “useful” members. The modern neonatal intensive care unit, which treats, and often saves, extremely ill newborn children, who during most of history would surely have died, has proven to be a setting where many of the age-old incentives for infanticide have begun to operate again. The “new infanticide” consists of withholding food or needed medical treatment from selected infants who suffer from one or more serious, though treatable, medical problems. The national government has now enacted legislation designed to curtail the practice of infanticide by the medical profession. This paper traces the genesis of that legislation, explores the problem to which it is addressed, and evaluates its prospects for success.
