Risk-Reducing Measures for Cancer Prevention.

Cancer, or malignancy, continues to be one of the most serious health problems in the world, leading to death and disability. Unlike in previous years, where new cases of cancer were predominant in developed nations, the number of cases of cancer and the resultant deaths are increasing in low- and middle-income countries. This is partially attributable to the current trend of adopting a Western lifestyle, substantial urbanization, and the rise in infections, such as the human papillomavirus (HPV) and hepatitis B virus (HBV), which together account for over 30% of cancer cases in underdeveloped and developing nations. The deleterious impact of cancer, as cases multiply worldwide, is multi-dimensional. Cancer exerts serious physical, psychological, and monetary burdens, not only on cancer patients but also on their family members, close friends, health care systems, and society at large. Importantly, over half of all cancer types can be prevented globally by mitigating the risk and causative factors as well as prompt adherence to scientifically recommended prevention measures. This review provides various scientifically based and people-centered strategies that every individual could adopt to reduce their risk of developing cancer in the future. It is recommended that, for these cancer prevention strategies to be effective, there should be a strong political will from the governments of individual countries to enact specific laws and implement policies that will significantly reduce sedentary lifestyles and unhealthy eating among the general public. Likewise, HPV and HBV vaccines, as well as cancer screenings, should be made available, affordable, and accessible on a timely basis for those who are eligible to take them. Finally, intensified campaigns and numerous informative and educational programs that promote cancer prevention should be initiated globally.

Diabetes Prevention and Measures to Ensuring a Healthy Lifestyle during COVID-19 Pandemic and after.

The incidence of diabetes mellitus (DM) is increasing exponentially globally, with 90% of the confirmed cases being type 2 DM. The global incidence of DM is expected to increase by 48% during 2017-2045. The coronavirus disease 2019 (COVID-19) pandemic continues to have a massive impact on human health, causing sudden lifestyle changes through quarantine measures, such as lockdown, social distancing, various curfews, and isolation at home. This in turn might increase the risk of developing numerous chronic diseases, such as DM, obesity, and cardiovascular diseases, which increase the severity of COVID-19. To this end, we performed a comprehensive review to determine viable measures for the prevention of DM and its subsequent upsurge globally. Additionally, we have determined strategies that should be adopted globally to ensure a healthy lifestyle during the COVID-19 pandemic and later.

Mental Health amid COVID-19 Pandemic: Appropriate Coping Strategies.

COVID-19 is a global public health crisis, and is turning to be a major mental health problem. This review provides a broad overview of mental health situations during COVID-19 pandemic in Africa and globally, while some preventive methods to improve mental health conditions during the pandemic were provided. In the Africa context, various government authorities must ensure the provision and accessibility to mental health care services such as routine preventive information, mental health counseling and self help measures, and social supports such as palliatives, basic needs and special financial assistance to the public during the pandemic. Generally, coping strategies such as personal care-based measures (adequate nutrition, personal hygiene, adequate sleep and rest) activity-based measures (regular physical exercise, learning new tasks and engaging in novel adventures and mindfulness meditation) and behavioral-based measures (avoidance of psychoactive substances, taking breaks from COVID-19-related information, social connectedness and showing supports to others, setting achievable targets, help seeking measures and psychiatrist's visitations, adherence to all COVID-19 preventive measures and uptake of the COVID-19 vaccines) are all viable preventive methods against mental health conditions during the pandemic globally. It is recommended that researchers should conduct more studies on the impacts of COVID-19 on mental health status in Africa populations to ensure a valid basis for proper interventions during and post pandemic era. Also, African countries should seek supports and routine guidance from appropriate international health organizations to ensure an updated and frequent mental health care delivery to the public.

Preventive Measures against the Development of Dementia in Old Age.

Dementia is a neurological condition characterized by numerous types of central nervous system diseases, which gradually deteriorates an individual's reasoning, rational thinking, and judgment abilities. As a serious public health concern that currently affects more than 50 million older adults, dementia is one of the most significant causes of incapacity, disability, and dependency among older adults. As new cases are expected to increase exponentially in the next three decades, dementia, which is not a normal feature of healthy aging despite the fact that it generally affects older adults disproportionately, requires enormous management and care efforts due to its associated socioeconomic, psychological, and physical burdens that involve the patient, their caregivers, guardians, family members, and society at large. Presently, there is no cure for dementia; however, this condition could be prevented. This narrative review aimed to provide a broad overview of studies detailing the alternative lifestyle modification-centered preventive measures against dementia. A comprehensive search of key databases to find articles related to this topic revealed that participating in regular physical activities, healthy eating and dieting, avoiding all forms of smoking, avoiding air pollutants, halting or reducing alcohol consumption, exercising the mind and being socially dynamic, getting enough rest and establishing good sleeping habits, infection prevention, stress prevention, avoidance of injuries, preventing the effects of social isolation and lockdowns, continuing education, and depression prevention are protective measures against the development of dementia.

The challenges to a successful COVID-19 vaccination programme in Africa.

The COVID-19 vaccination campaign is an ongoing worldwide effort to vaccinate large numbers of people against COVID-19 in order to ensure protection from the disease, control the rate of infection, reduce severe outcomes, and get back to normal life. Most African countries had a delay in the initiation of their COVID-19 vaccine national rollout compared to other regions in the world, and the goal of the immunization exercise in the continent is to vaccinate over 60% of the African population to attain herd immunity. Over the years, vaccination programmes are usually faced with challenges in Africa because of numerous factors. So far, some of the major challenges threatening the success of the COVID-19 vaccination rollout in most African countries includes the slow onset of the vaccination exercise, limited funds, concerns around vaccine safety and uncertainties, storage requirements and regulatory hurdles for vaccines, limited shelf life of COVID-19 vaccines, inability to access vulnerable communities in a timely fashion, problems around the use of different vaccines, and wars and conflicts. The solutions and other imperative recommendations to these challenges were provided so as to optimize the vaccination programme and to achieve an appreciable success in the COVID-19 vaccination programme on the continent. In conclusion, a holistic and timely planning, fast execution of plans, rigorous community involvement, and a robust multi-sectoral partnership will ensure a successful COVID-19 vaccination campaign in Africa.

COVID-19 (SARS-CoV-2) pandemic: fears, facts and preventive measures.

The aim of this review is to give a synopsis on the coronavirus disease 2019 (COVID-19) pandemic, with major focus on the preventive measures. Ever since the influenza pandemic of 1918, and the second world war of (1939-1945), the world has not been faced with a common problem in recent memory like the COVID-19 pandemic. The unprecedented COVID-19 pandemic is caused by infection with a viral pathogen, the nascent severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), and is characterized by respiratory failure in severe cases. The communicability period of COVID-19 varies, but it is usually between 2-14 days, and the major signs and symptoms of COVID-19 are high temperature (fever), severe and consistent cough, and serious breathing problems in severe cases, however, complications result in the serious inflammation of the lungs, and organ malfunction occurs in patients with comorbidities and health conditions especially diabetes, heart disease and obesity. With high virulence and contagious nature of SARS-CoV-2, over 11.4 million confirmed cases and over 533,780 deaths have occurred as a result of COVID-19 globally, with over 6.1 million recoveries as of 6th July 2020. Presently, there is no known cure for COVID-19, however, remdesivir has been approved for emergency use for the treatment of COVID-19 patients by the Food and Drug Administration, a United States federal regulatory body (FDA), while various clinical trial treatments and vaccines are being tried globally. The world is faced with containing the spread of the infection, and this review revealed that thorough hand washing with antiseptic soap and running water and usage of alcohol hand sanitizer, frequent surfaces cleaning, strict adherence to social distancing, regular respiratory hygiene, wearing of protective face masks, frequent testing, self-isolation, quarantine and rigorous contact tracing will help to prevent further spread, and control the transmission of the viral pathogen. It is however strongly recommended that only the strict compliance to the mitigative and preventive measures provided above will yield the desired results in the prevention, management and control of the COVID-19 pandemic.

COVID-19: An International Public Health Concern.

This review presents a synopsis on the current COVID-19 pandemic, with focus on preventive measures. COVID-19 is a new viral infection, and is in form of a positive-sense, single-stranded RNA Coronavirus which belongs to an expanded group of viruses which were identified six decades ago. Importantly, the new COVID-19 belongs to the group of SARS-CoV, and it originated in bats but infected humans through smuggled pangolins. At first, the mode of transmission of infection was animal-to-person, but person-to-person and community transmission of the virus has been confirmed in many parts of the world. With an incubation period of between two-fourteen days, signs and symptoms of infection are mild to high respiratory illness; characterized with cough, breathing problems (shortness of breath), high temperature (Fever), tiredness (Fatigue) and nausea. Presently, no vaccines or specific treatment is available for COVID-19, in light of the aforementioned; prevention is the only substantial and less expensive option. With the envisaged explosive community transmission of COVID-19 in the coming weeks in places with limited daily testing, especially in African countries, it is recommended among many that social distancing which includes avoiding any form of contact with people; either through greetings, hugging or shaking of hands and large gatherings, avoid contact with animal items, dead or alive animals, sick and dead people from areas experiencing COVID-19 epidemic, and basic hygienic practices like thorough washing of hands with clean water and antiseptic soap for the duration of at least twenty seconds should be practiced always. However, in the absence of the aforementioned, an alcohol-based hand gel should be used on the hands frequently. Furthermore, health care workers should adhere strictly to the standard preventive measures in areas of heightened COVID-19 epidemic.

Contemporary Nigerian public health problem: prevention and surveillance are key to combating cholera.

Cholera is a public health problem around the world, and it is endemic in Africa, parts of Asia, the Middle East as well as South and Central America. This review characterizes an cholera outbreak in Nigeria in 2017/2018. On the basis of own experiences and the analysis of historical outbreaks, the Vibrio cholera strains, mode of transmission, signs and symptoms, and most important the prevention and control measures are identified. Untreated, the lethality of cholera is up to 70%. Therefore, a multifaceted approach including public policy, surveillance, water purification and hygiene, community sensitization, and the use of oral cholera vaccination (OVC) is vital to prevent, control, and reduce the cholera mortality rate. It is recommended that the government pass legislation to implement preventive and surveillance measures, e.g., invest in drinking water systems, sanitation systems and sewage treatment, and promote public education on basic hygiene. The latter includes boiling and treating water before drinking, washing hands frequently with soap and clean water, thoroughly cooking food before consumption, avoiding open defecation, disposing of wastes properly, and immediately taking anyone with signs and symptoms of cholera such as watery diarrhea to the hospital for treatment.
