Background: The COVID-19 pandemic constitutes a global health threat and poses a major burden on the African continent. We assessed the real-world burden of COVID-19 infection in African Union (AU) member states to determine the distributional patterns of epidemiological measures during the first 1 year of the pandemic. Methods: This retrospective cross-sectional study utilized COVID-19 data from publicly available data repositories of the African Center for Disease Control and Prevention and Our World in Data for the period February 2020 to January 2021. AU member states were classified into low, medium, and high burdens based on COVID-19 morbidity. We conducted descriptive and inferential analyses of COVID-19-reported cases, deaths, recoveries, active cases, COVID-19 tests, and epidemiological measures that included morbidity and mortality rates, case fatality rate (CFR), and case ratios. Results: A total of 3.21 million cases were reported during the 1-year period, with 2.6 million recoveries, 536,784 cases remaining active, and 77,486 deaths. Most countries (49.1%, n = 26) in AU experienced a low burden of COVID-19 infection compared to 28.3% (n = 15) with medium burden and 22.6% (n = 12) with high burden. AU nations with a high burden of the disease were mainly in the northern and southern regions. South Africa recorded the highest number of cases (1.31 million), followed by Morocco with 457,625 and Tunisia with 175,065 cases. Correspondently, death tolls for these countries were 36,467, 7888, and 5528 deaths, respectively. Of the total COVID-19 tests performed (83.8 million) during the first 1 year, 62.43% were from high-burden countries. The least testing occurred in the medium-burden (18.42%) countries. The overall CFR of AU was 2.21%. A morbidity rate of 327.52/105 population and mortality rate of 5.96/105 population were recorded during the first 1-year period with significant variations (p < 0.0001) across burden levels. Continental morbidity and mortality rates of 17,359/105 and 315.933/105 populations were recorded with significant correlation (r = 0.863, p < 0.0001) between them and variations across selected epidemiological measures by COVID-19 burden levels. Conclusion: Understanding the true burden of the disease in AU countries is important for establishing the impact of the pandemic in the African continent and for intervention planning, preparedness, and deployment of resources during COVID-19 surges and future pandemics.

government measures to contain the COVID-19 pandemic cannot be effective without widespread compliance by the public. A greater understanding of citizens' perceptions of these measures can help government agencies adapt their strategies to boost compliance. We examined citizens' perceptions of government's measures to contain the COVID-19 pandemic and its implications on compliance using data from Onitsha city, Anambra State Nigeria. data was obtained through in-person interviews of 140 consenting adults in March 2020. Descriptive and inferential statistics were used to summarize the data. most participants (84.7%) doubted government's ability to manage the COVID-19 outbreak, raising concerns about ineffective governance (25.7%) and inadequate health facilities (20.7%). However, participants expressed a favorable perception of school closures (92.3%) and a ban on large gatherings (83.9%), driven mostly by the need to contain the COVID-19 and avoid its spread. But, they were generally indifferent about the closure of the markets and workplaces due to concerns for food insecurity and lack of government's relief programs. Participants who had a positive perception of the ban on large gatherings were more likely to have high knowledge and to adopt good COVID-19 preventive practices. the study showed a lack of public's confidence in the government's ability to manage the pandemic. This provides an opportunity for the city government and the public to reflect on the existing relationships, build mutual trust, and devise collaborative engagement that will boost compliance and help contain the devastating impact of COVID-19 pandemic.

Background The utilization of modern-immunotherapies, notably immune checkpoint inhibitors (ICIs), has increased markedly in patients with metastatic melanoma over the past decade and are recommended as standard treatment. Given their increasing adoption in routine care for melanoma, understanding patient access to immunotherapy and patterns of its use in Texas is crucial as it remains one of the few states without Medicaid expansion and with high rates of the uninsured population. The objectives of this study were to examine the trend in the utilization of immunotherapy and to determine factors associated with immunotherapy utilization among patients with metastatic melanoma in the era of ICIs in Texas. Methods A retrospective cohort study was conducted using the Texas Cancer Registry (TCR) database. The cohort comprised of adult (≥ 18 years) patients with metastatic melanoma diagnosed between June 2011 and December 2018. The trend in immunotherapy utilization was assessed by determining the proportion of patients receiving immunotherapy each year. The Average Annual Percent Change (AAPC) in immunotherapy utilization was assessed using joinpoint regression, while multivariable logistic regression was used to determine the association between patient characteristics and immunotherapy receipt. Results A total of 1,795 adult patients with metastatic melanoma were identified from the TCR. Immunotherapy utilization was higher among younger patients, those with no comorbidities, and patients with private insurance. Multivariable analysis showed that the likelihood of receipt of immunotherapy decreased with older age [(adjusted Odds Ratio (aOR), 0.92; 95% CI, 0.89– 0.93, p  = 0.001], living in high poverty neighborhood (aOR, 0.52; 95% CI, 0.44 – 0.66, p  < 0.0001), having Medicaid (aOR, 0.58; 95% CI, 0.44 – 0.73, p  = 0.02), being uninsured (aOR, 0.49; 95% CI, 0.31 – 0.64, p  = 0.01), and having comorbidities (CCI score 1: aOR, 0.48; 95% CI, 0.34 – 0.71, p  = 0.003; CCI score ≥ 2: aOR, 0.32; 95% CI, 0.16 – 0.56, p  < 0.0001). Conclusions and relevance This cohort study identified sociodemographic and socioeconomic disparities in access to immunotherapy in Texas, highlighting the need for policies such as Medicaid expansion that would increase equitable access to this innovative therapy.

The study describes the HIV care providers' sociodemographic and medical practice characteristics and the health care services offered to patients during medical care encounters in Houston/Harris County, Texas. We used data from the pilot cycle of the Centers for Disease Control and Prevention Medical Monitoring Project Provider Survey conducted in June to September 2009. The average age and HIV care experience of the providers were 46.7 and 11.7 years, respectively, and they provided care to an average of 113 patients monthly. The average proportion of HIV-infected patients seen per month by race/ethnicity was 43.3% for blacks, 28.5% for whites, 26.6% for Hispanics, 1.3% for Asians, and 0.6% for other races. A total of 67% of providers offered HIV testing to all patients 13 to 64 years of age. Most HIV care providers (73.9%) reported that patients in their practices sought HIV care only after experiencing symptoms. Understanding the HIV care delivery system from providers' perspectives may help enhance support services, patients' ongoing care and retention, leading to improved health outcomes.

Background: The current US HIV treatment guidelines support initiation of antiretroviral therapy (ART) for persons with HIV for personal health benefits and prevention of HIV transmission. However, high levels of adherence to ART are critical to maximize individual and public health benefits. We examined the nonclinical barriers to ART initiation for clinically eligible individuals and the provider- and patient-related factors associated with these barriers among HIV-infected patients in Houston/Harris County, Texas. Methods: We analyzed data obtained from a probability sample of HIV medical care providers (HMCPs) in 13 outpatient facilities in Houston/Harris County, Texas surveyed between June and September 2009. We used an inductive thematic approach to code HMCP responses to an open-ended question that asked the main reasons why providers may delay initiating ART for clinically eligible patients. Results: The reasons cited by providers for delaying ART for clinically eligible patients were adherence (42.5%; 95% confidence interval [CI]: 28.5-57.8), acceptance (30%; 95% CI: 18.1-45.4), and structural concerns (27.5%; 95% CI: 16.1-42.8), with significant variations (P < .0001) noted across patients’ race/ethnicity and transmission category. HIV medical care providers with 6 to 10 years’ experience in HIV care and those providing medical care for more than 100 patients monthly were about 4 times (adjusted odds ratio [aOR]: 3.80; 95% CI: 1.20-5.92; P = .039) and 10 times (aOR: 10.36; 95% CI: 1.42-22.70; P = .019) more likely to state adherence and acceptance concerns, respectively, as reasons for delaying ART for clinically eligible patients. Conclusion: Our findings highlight the fact that clinical guidelines are only a starting point for medical decision-making process and that patients themselves play an important role. HMCP access to referrals for other medical issues, support services, and treatment education may help improve adherence and patient readiness for ART, thereby avoiding systemic delays.

In the United States, a considerable number of people diagnosed with HIV are not receiving HIV medical care due to some barriers. Using data from the Medical Monitoring Project survey of HIV medical care providers in Houston/Harris County, Texas, we assessed the HIV medical care providers’ perspectives of the system and patient barriers to HIV care experienced by people living with HIV/AIDS (PLWHA). The study findings indicate that of the 14 HIV care barriers identified, only 1 system barrier and 7 patient barriers were considered of significant (P ≤ .05) importance, with the proportion of HIV medical care providers’ agreement to these barriers ranging from 73.9% (cost of health care) to 100% (lack of social support systems and drug abuse problems). Providers’ perception of important system and patient barriers varied significantly (P ≤ .05) by profession, race/ethnicity, and years of experience in HIV care. To improve access to and for consistent engagement in HIV care, effective intervention programs are needed to address the barriers identified especially in the context of the new health care delivery system.

BackgroundSuboptimal adherence to direct oral anticoagulants (DOACs) among atrial fibrillation (AF) patients remains currently a major concern due to the increased risk of cardiac and thromboembolic events.AimTo identify longitudinal distinct trajectories of DOAC adherence and sociodemographic and clinical factors associated with each trajectory.MethodPatients with AF who were prescribed with DOAC from July 2016–December 2017 were identified among patients enrolled in the Medicare Advantage Plan. Patients were followed up for a year after the index date to calculate the monthly proportion of days covered (PDC). The monthly PDC was incorporated into the logistic group-based trajectory model to evaluate distinct patterns of adherence. A multinomial regression model was carried out to assess various predictors associated with each trajectory. Sub-group analysis was conducted among incident DOAC users.ResultsTotal of 1969 patients with AF, four distinct trajectories of adherence were selected: adherent 36.8%, gaps in adherence 9.3%, gradual decline in adherence 29.7%, and rapid decline in adherence 24.2%. Significant predictors associated with suboptimal adherence trajectories were age (75 years or older), gender (male vs female), low-income subsidy health plan, prevalent users, and presence of comorbidities. Among 933 incident users, three adherence trajectories were identified: adherent trajectory (31.8%), rapid decline in adherence (32.5%), and gradual decline in adherence (35.6%). The significant predictors among incident users were gender (male vs female), low-income subsidy health plan, HAS-BLED score ≥ 2, and presence of coronary artery disease.ConclusionAdherence to DOACs was suboptimal among the total population and incident users.

Few studies have estimated complete antiretroviral therapy (ART) adherence following HIV infection since the advent of the new ART guidelines in 2012. This study determined the prevalence and influence of sociodemographic, behavioral, and clinical factors on complete ART adherence among people living with HIV (PLWH) receiving medical care in Houston/Harris County, Texas. Data from the Houston Medical Monitoring Project survey collected from 2009 to 2014 among 1073 participants were used in this study. The primary outcome evaluated was combined adherence, defined as complete, partial, and incomplete combined adherence based on three ART adherence types-dose, schedule, and instruction adherence. The duration living since initial HIV diagnosis was classified as <5, 5-10 and >10 years. Rao-Scott Chi-square test and multivariable proportional-odds cumulative logit regression models were employed to identify the sociodemographic, behavioral, and clinical characteristics of complete combined adherence among the three groups of PLWH living with HIV infection. More than one-half (54.4%) of PLWH had complete, 37.4% had partial, and 8.3% had incomplete combined adherence. Among these PLWH, 52.2% had been infected with HIV for >10 years, and 26.5% and 21.4% were infected for <5 years and 5-10 years, respectively. PLWH who were diagnosed <5 and 5-10 years were two times (aOR=1.71, 95% CI=1.13-2.57; aOR=1.69, 95% CI=1.10-2.59; respectively) more likely to experience complete combined adherence than those with >10 years of infection. Multiple sociodemographic, behavioral, and clinical characteristics were significantly associated with complete adherence and varied by the duration of HIV infection. Measures of adherence should include all adherence types (dose, schedule, instruction), as utilizing a single adherence type will overestimate adherence level in PLWH receiving medical care. Intervention efforts to maintain adherence should target recently infected PLWH, while those aimed at improving adherence should focus on longer infected PLWH.

Background: Sex workers, like others, are facing economic hardships and anxiety about their health and safety due to coronavirus disease-2019 (COVID-19), an infectious disease caused by a novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Universally, most sex work has largely reduced, moved online, or undertaken covertly because of lockdown measures and need for social distancing to break the transmission of SARS-CoV-2. However, the ability of sex workers to protect themselves against COVID-19 depends on their individual and interpersonal behaviors and work environment. In this study, we sought to determine the relationships between COVID-19 knowledge, awareness and prevention practice (KAP) among female commercial sex workers (FCSW) in the Niger Delta region of Nigeria to inform the development of prevention interventions for this vulnerable population. Methods: Data used in this study were obtained from a cross-sectional survey of 604 FCSW operating in the Niger Delta region of Nigeria. We used descriptive and inferential statistics to assess their socio-demographic characteristics and COVID-19 KAP adopted against the novel coronavirus. Latent class analysis was used to systematically classify participants' attributes and behaviors into the most likely distinct clusters or risk groups. Results: The majority of the FCSW were singles (86.8%) of childbearing ages, 21-35 years (86.2%), with almost three quarters (73.2%) of them having sex with 3-4 clients per day during the COVID-19 pandemic. Overall, almost three quarters of the participants had both good knowledge and awareness about COVID-19 but less than half of them (41.1%) implemented good practice to prevent the spread of the disease. However, a highly significant and positive relationship was recorded between COVID-19 knowledge (r=0.90, p<0.0001) and awareness (r=0.65, p<0.0001), and preventive practice of FCSW, respectively. About 89.1% of the participants were not very familiar with the symptoms of COVID-19 (p<0.0001). Only 10.9% of the FCSW indicated that they wear facemask at all times, while 45.2% of them do not wear facemask during sexual intercourse with their clients (p<0.0001). Based on the FCSW attributes and behaviors, we identified three distinct clusters or risk groups (p<0.0001), namely, low-risk takers (Cluster 1), high-risk takers (Cluster 2) and very high-risk takers (Cluster 3) with latent class prevalence rates ([[gamma].sub.c]) of 41.13% (95% CI: 37.26-45.10), 33.17% (95% CI: 29.53-37.02) and 25.71% (95% CI: 22.38-29.34), respectively. Conclusion: Sex work has high transmission potentials for SARS-CoV-2 because of its operational nature, which does not permit social distancing, and thus, renders certain preventive measures practically ineffective. This is a major challenge in the fight against COVID-19 in this high-risk group and calls for the development of operational guidelines and targeted intervention strategies to help reduce the spread of COVID-19 in the Niger Delta region.
