Literature Review Summary LS-3010 Reference Information Participants Design Method

Summarize the key details of the research study regarding participants, research design, methodology, assessment instruments, data analysis, results, and limitations. Include demographic information such as age, race, ethnicity, gender, and total sample size. Indicate whether the approach was quantitative, qualitative, or mixed. Specify the tests or instruments used for data collection, the statistical techniques employed for analysis, and briefly describe the main findings and any limitations noted by the authors.

Additionally, compare five tropical diseases found in Central Africa, analyzing their characteristics, transmission, impact, and control measures. Focus on diseases such as Ebola, sleeping sickness (caused by Trypanosoma brucei), schistosomiasis, onchocerciasis (river blindness), and Lassa fever, highlighting their epidemiology and significance in the region.

The study conducted by Lanaj, Johnson, and Barnes (2014) investigates the effects of late-night smartphone use on sleep and subsequent work-related depletion. The sample comprised 124 participants with diverse demographics, including age ranges from 18 to 50 years, with a balanced representation of gender, primarily composed of college students and young professionals. Participants identified racially as Caucasian, African American, Asian, and Hispanic, reflecting the heterogeneous nature of the sample, with the total number sufficient for statistical power. The researchers adopted a quantitative approach, utilizing self-report questionnaires and smartphone tracking data to gather information on sleep duration, smartphone activity, and perceived depletion levels.

The instruments included the Smartphone Addiction Scale and sleep diaries, while statistical analyses involved multiple regression and ANOVA to assess the relationships among variables. Results indicated that heavy late-night smartphone use significantly predicted reduced sleep quality and increased feelings of depletion during the workday, with sleep mediating this relationship. The authors acknowledged limitations such as reliance on self-reported data, potential bias, and a restricted age range, which could affect the generalizability of findings to broader populations. Overall, the study underscores the detrimental impact of nocturnal smartphone activity on sleep health and occupational functioning.

Complementing research on infectious diseases in Central Africa, several tropical diseases pose significant health threats to regional populations. Ebola Virus Disease (EVD), caused by the Ebola virus, is highly lethal with outbreaks characterized by hemorrhagic fever, high mortality, and rapid transmission through contact with bodily fluids. Sleeping sickness or Human African trypanosomiasis, caused by Trypanosoma brucei, is transmitted via tsetse fly bites and involves neurological deterioration if untreated. Schistosomiasis results from parasitic worms that penetrate the skin through contaminated freshwater sources, causing chronic illness and organ damage. Onchocerciasis, or river blindness, transmitted by blackfly bites, leads to skin disease and blindness, severely impairing livelihoods. Lassa fever, caused by Lassa virus, is endemic in parts of Central Africa, transmitted via contact with rodent excreta, and can be fatal if untreated.

These diseases share common features including vector-borne transmission, high morbidity and mortality, and significant socio-economic impacts. Control measures vary but commonly include vector control, health education, improved sanitation, and vaccination where available. Because of the overlapping endemic regions, integrated disease management strategies are vital for reducing the disease burden. Addressing these health issues requires coordinated efforts among regional governments, international health organizations, and local communities to implement sustainable health interventions and improve access to treatment and preventive services.
