There is a lack of detailed information on the epidemiology, prevention, and treatment of gambling disorder (GD) in Nigeria, a country that has the second-largest online sports gaming market in Africa. The objective of this review article was to emphasize the need for a nationwide epidemiological study on the GD caused by compulsive sports betting in Nigeria. The literature searches were carried out using the PubMed, Scopus, and Web of Science electronic databases regarding articles concerning sports betting, problem gambling, GD, and mental health in Nigeria using the following medical subject headings: Pathological Gambling AND Gamblings AND Federal Republic of Nigeria AND Social Epidemiology. A nationwide surveillance is necessary to determine the epidemiology, risk factors, and prevention and treatment measures for GD in Nigeria. To prevent negative public health consequences, sports gambling activities in Nigeria should be restricted and controlled. There is a need to set aside strict measures to control both legal and illegal online and offline sports betting activities in Nigeria. Moreover, the implementation of an effective mental health-care delivery policy to tackle gambling addiction and associated psychiatric comorbidities in Nigeria will enable efficient diagnosis and treatment of individuals with GD and improve relapse prevention. A well-funded and functional mental health-care system and research framework will facilitate effective mental health-care delivery among individuals at risk of GD and patients with GD in Nigeria. Expanding access to and use of mental health treatment services could substantially reduce the prevalence of GD and associated comorbidities in Nigeria. [ABSTRACT FROM AUTHOR]

Background The objectives of this study were to assess the knowledge, attitudes and control practices among the staff and students of Nnamdi Azikiwe University (NAU), Awka, Anambra State, Nigeria, regarding venomous arthropods. Methods The knowledge, attitudes and control practices regarding venomous arthropods were assessed in 350 participants. Results The respondents were aware of the presence of venomous arthropods at NAU and they had seen them on campus, with spiders (40.44%) being the most common and electric ants (1.39%) being the least common. The control practices applied to limit the activities of these arthropods included keeping the environment clean (40.80%), the use of insecticides (37.33%), the use of repellents (8.68%), spraying houses with kerosene (7.81%), spraying of fuel on the arthropods (3.47%), screening of houses (1.39%) and the use of bed nets (0.52%). Conclusions An assessment and determination of knowledge, attitudes and control practices regarding venomous arthropods among the staff and students of NAU is necessary in order to improve the preventive measures to reduce injuries caused by venomous arthropod encounters, which are some of the most underestimated health hazards in tropical regions, including southeastern Nigeria, affecting primarily rural communities. According to the findings of our study, students and staff at NAU are rarely involved in life-threatening incidents as a result of their encounters with venomous arthropods and most apply several globally accepted standard practices for the control of venomous arthropods.

Presently, there is a rise in the use of mobile phones, laptops, and wireless internet technologies such as Wi-Fi and 5G routers/modems across the globe; these devices emit a considerable amount of electromagnetic radiation (EMR) which could interact with the male reproductive system either by thermal or nonthermal mechanisms. The aim of this review was to examine the effects of mobile phone use on male fertility. Related studies that reported on the effects of EMR from mobile phones on male fertility from 2003 to 2020 were evaluated. PubMed database was used. The Medical Subject Heading system was used to extract relevant research studies from PubMed. Based on the outcomes of both human and animal studies analyzed in this review, animal and human spermatozoa exposed to EMR emitted by mobile phones had reduced motility, structural anomalies, and increased oxidative stress due to overproduction of reactive oxygen species. Scrotal hyperthermia and increased oxidative stress might be the key mechanisms through which EMR affects male fertility. However, these negative effects appear to be associated with the duration of mobile phone use. [ABSTRACT FROM AUTHOR]

Background: Sleep is a vital physiological process regulated by the circadian clock and homeostatic mechanisms. Shift work is necessary to ensure continuity of healthcare provision. Worldwide, nurses work night shifts on a rotational or permanent basis., Objective: To analyse the impact of circadian rhythm disruption due to night shift work on the mental wellbeing of nurses., Methods: The literature search was conducted using PubMed and Scopus electronic databases. Selection criteria include studies published in English between 1997 and 2021 that examined the impact of night-shift work on the mental health of nurses., Results: The searches generated a total of 22 records on the PubMed database, and 9 records on the Scopus database, and a total of 31 studies. 29 papers were identified after removal of duplicates. However, 29 articles were screened based on the review of titles and abstracts. 19 articles were identified for full-test review. Seven papers were included in this review., Conclusions: Disrupted circadian rhythms and poor sleep quality and quantity have been identified as two of the most significant elements in the long-term effects of night-shift work on nurses' mental health. Strategies and policies to promote workplace health may reduce the occurrence of mental health disorders among night-shift nurses, whether the shifts are rotational or permanent. Nursing supervisors and hospital administrators should consider developing new guidelines to minimize the negative impact of night shift rotations on mental health and the quality of life among nurses.
