Prevalence of Asymptomatic Malaria Parasitemia among Blood Donors in Cape Coast, Ghana: A Cross-Sectional Study.

Background: Malaria is an important transfusion-associated infection in many parts of the world, particularly in sub-Saharan Africa, where it is endemic. We studied the prevalence of malaria parasites among blood donors in the Cape Coast Metropolitan Area. Methods: A malaria parasite examination was added to the blood donor screening protocol for 240 voluntary and replacement blood donors (224 males and 16 females) between December 2020 and July 2021. Results: Overall, 2.5% (6/240) had Plasmodium falciparum trophozoites detected in their blood sample. The remaining had no parasites detected. Four of the 148 who passed the blood donor screening tests were infected. The remaining two with malaria parasites failed one screening test. These included one donor with "hepatitis B + P. falciparum" and another with "syphilis + P. falciparum" parasite coinfection. All blood donors who had malaria parasites detected in their blood were males. Most donors, 45.8% (110/240), were in the 26-35 age group, with the highest prevalence of 1.3% (3/240). Blood group O was predominant (75.0%, 180/240), followed by B (12.9%, 31/240), A (11.3%, 27/240), and AB (0.8%, 2/240). All malaria parasites detected were among individuals with blood group O. Moreover, 96.3% (231/240) were rhesus-positive and had the highest prevalence of 2.1% (5/240). Conclusions: Screening of blood donors in Ghana does not include malaria, although there is the potential for transmission through blood products. Malaria transmission via blood transfusion remains an issue of public health concern, as indicated in the results of this current study. We recommend studies on malaria prevention, pretransfusion and posttransfusion, and pathogen reduction technology.

Implicit Racial Bias, Health Care Provider Attitudes, and Perceptions of Health Care Quality Among African American College Students in Georgia, USA.

OBJECTIVE: Due to racism, over 20% of African Americans, including college students in Georgia, receive poor quality health care. Consequently, most students are reluctant to utilize health care services in the state. This study examined biased racial attitudes of health care providers in Georgia, and African American Georgia State University (GSU) School of Public Health (SPH) students' perceptions of the quality of health care they receive from providers, the effects of such care, and student recommendations for the way forward. DESIGN: A mixed-methods cross-sectional design was used to collect data from 63 students across six domains using Qualtrics. RESULTS: Provider brushes off patient concerns when providing medical care (29.9%), stereotyping (26.9%), and the lack of communication during medical care (25.4%) were the three main implicit racial attitudes identified by GSU SPH students. Owing to the poor quality of care they receive from their health care providers, some students (28.4%) are reluctant to utilize health care services, distrust doctors that are not from their race (34.3%), do not adhere to treatment (19.4%), and prefer to use home remedies (28.4%) when ill. Students recommended cultural competency training, holding health care providers accountable for their actions, and increasing African American health care providers in Georgia as ways to address health care provider attitudes and quality of care. CONCLUSION: Negative provider attitudes impact the health and health-seeking behavior of African American college students in Georgia. These attitudes must be eliminated so barriers to clinical participation are removed, and student health outcomes optimized.

Voluntary Counseling and Testing, Antiretroviral Therapy Access, and HIV-Related Stigma: Global Progress and Challenges.

To date, about 37 million people are living with the human immunodeficiency virus (HIV) and an estimated 680,000 people have died from acquired immune deficiency syndrome (AIDS) related illnesses globally. While all countries have been impacted by HIV, some have been significantly more impacted than others, particularly countries in sub-Saharan Africa. The purpose of this paper was to identify progress made in HIV prevention globally, particularly in the areas of voluntary counseling and testing (VCT) uptake, access to antiretroviral therapy (ART), and HIV-related stigma. With the development of ART, a cocktail of medications for the treatment of HIV, VCT uptake increased, as it became apparent that the medication would only be prescribed after an HIV diagnosis through testing. Widely considered a critical gateway to HIV prevention and treatment, VCT is being implemented in many countries, and as a result, about 38 million people living with HIV in 2018 had access to ART. Regardless of this success, major challenges still remain. We did an electronic search of 135 articles in English related to global HIV progress and challenges indexed in PubMed, ResearchGate, Google, and other search engines from 1998 to 2021. Sixty articles met the inclusion criteria for this paper. Data on trends in ART coverage were obtained from the Joint United Nations Programme on HIV/AIDS (UNAIDS) website. These data were used to show ART coverage globally in World Health Organization (WHO) regions. It was found that while global successes have been chalked in the areas of VCT uptake and ART coverage, HIV-related stigma has impeded greater success. This paper summarizes and discusses global successes and challenges in HIV prevention efforts in the past four decades with a focus on VCT, ART, and HIV-related stigma.

Utilization of Rapid Diagnostic Testing in sub-Saharan Africa: Challenges and Effects on HIV Prevention.

The human immunodeficiency virus (HIV) remains a global threat to health. To prevent and control the disease caused by the virus, developed and developing countries continue to invest heavily in research and equipment so as to accurately detect the virus. The utilization of highly sensitive and effective rapid diagnostic tests (RDTs) have the potential to detect HIV in high-burden countries, especially those in sub-Saharan Africa (SSA). Yet, in SSA, challenges associated with HIV-RDT result inaccuracy, HIV misdiagnosis, poor tester capacity, and the improper storage of HIV-RDT kits have negatively impacted the benefits, and threaten to undermine HIV prevention. This paper focuses on the utilization of RDTs in HIV diagnosis in SSA, HIV-RDT challenges, and the effects of HIV-RDT challenges on HIV prevention. Subsequent to reviewing available literature, the authors found that although HIV-RDTs can negatively impact HIV-prevention efforts in SSA due to the likelihood of false positive HIV diagnoses, they generally provide quick results for people in resource poor settings, and do not require them to return to the testing sites to obtain their results. Obtaining accurate rapid HIV results means people who test positive can immediately seek care and take steps to prevent future transmission of the virus.

An Evaluation of Treatment Outcomes in a Cohort of Clients on the DOTS Strategy, 2012-2016.

We present, for the first time, an evaluation of treatment outcomes in a cohort at a TB referral centre in the Central Region of Ghana. Of the 213 clients placed on DOTS, 59.2% (126/213) were sputum smear-positive. An overall cure rate of 90.2% (51.6% cured + 37.6% completed) and a death rate of 8.5% (18/213) were estimated. Of the number of clients who died, 5.7% (12/213) were males (χ2 = 2.891, p = 0.699; LR = 3.004, p = 0.699). Deaths were only recorded among clients who were > 19 years old (χ2 = 40.319, p = 0.099; LR = 41.244, p = 0.083). Also, 0.9% (2/213) was lost to follow-up, while 1.4% (3/213) had treatment failure. In total, 13.6% (7.0%, 15/213 males, and 6.6%, 14/213 females) of clients who were placed on DOTS were HIV seropositive. Ages of 40-49 years had the highest number, 13/213 (6.1%), infected with HIV, though the difference among the remaining age groups was not statistically significant (χ2 = 9.621, p = 0.142). Furthermore, 7.0% (15/213) had TB/HIV coinfection. Out of them, 9 were cured and 5 died at home, while 1 had treatment failure. Tuberculosis/HIV infection prevention advocacy and interventions that address sociodemographic determinants of unfavourable treatment outcomes are urgently required to augment national efforts towards control.

Discordant HIV Test Results: Implications on Perinatal and Haemotransfusion Screening for HIV Infection, Cape Coast, Ghana.

Screening results of 488 pregnant women aged 15-44 years whose blood samples had been tested on-site, using First Response® HIV 1/2, and confirmed with INNO-LIA™ HIV I/II Score were used. Of this total, 178 were reactive (HIV I, 154; HIV II, 2; and HIV I and HIV II, 22). Of the 154 HIV I-reactive samples, 104 were confirmed to be HIV I-positive and 2 were confirmed to be HIV II-positive, while 48 were confirmed to be negative [false positive rate = 17.44% (13.56-21.32)]. The two HIV II samples submitted were confirmed to be negative with the confirmatory test. For the 22 HIV I and HIV II samples, 7 were confirmed to be HIV I-positive and 1 was confirmed to be HIV I- and HIV II-positive, while 14 were confirmed to be negative. Of the 310 nonreactive samples, 6 were confirmed to be HIV I-positive and 1 was confirmed to be HIV II-positive [false negative rate = 5.79% (1.63-8.38)], while 303 were negative. False negative outcomes will remain unconfirmed, with no management options for the client. False negative rate of 5.79% requires attention, as its resultant implications on control of HIV/AIDS could be dire.
