COVID-19 Outcomes among People Living with HIV in Colorado.

It is known that people who are immunocompromised or have a comorbidity are at an increased risk for acquiring COVID-19, having a longer duration of COVID-19 symptoms, and a greater likelihood of severe outcomes, including people living with HIV (PLHIV) (Centers for Disease Control and Prevention. (n.d.). Basics of covid-19. Centers for Disease Control and Prevention. Retrieved October 31. 2022, from https://www.cdc.gov/coronavirus/2019-ncov/your-health/about-covid-19/basics-covid-19.html ). However, treatment for PLHIV can greatly reduce the amount of HIV in a person's blood, known as viral suppression. This study compared the outcome of COVID-associated hospitalization among virally suppressed and unsuppressed PLHIV in Colorado. A retrospective cohort analysis was conducted including all known PLHIV in Colorado that were diagnosed with COVID-19 between March 2020 and September 2022. Relevant covariates were identified including race/ethnicity, age at time of diagnosis, region of diagnosis, and vaccination status. An initial univariate logistic regression was then built to test the statistical significance of the association between viral suppression and hospitalization. The final model included all associated covariates and crude and adjusted odds ratios were analyzed. When controlling for covariates, PLHIV who were not virally suppressed at the time of their COVID-19 diagnosis were 2.5 (OR 2.5, 95% CI 1.6-4.0) times as likely to be hospitalized at the time of their first COVID-19 diagnosis compared to those that were suppressed. These findings suggest that viral suppression among PLHIV is protective against poor COVID-19 outcomes. This study is an important first step in highlighting the importance of PLHIV being retained in care and achieving viral suppression in reducing hospitalizations due to COVID-19 in Colorado.

SARS-CoV-2 Prevalence among Outpatients during Community Transmission, Zambia, July 2020.

During the July 2020 first wave of severe acute respiratory syndrome coronavirus 2 in Zambia, PCR-measured prevalence was 13.4% among outpatients at health facilities, an absolute difference of 5.7% compared with prevalence among community members. This finding suggests that facility testing might be an effective strategy during high community transmission.

COVID-19 Severity and COVID-19-Associated Deaths Among Hospitalized Patients with HIV Infection - Zambia, March-December 2020.

The effect of HIV infection on COVID-19 outcomes is unclear. Studies in South Africa (1) and the United Kingdom (2) found an independent association between HIV infection and COVID-19 mortality; however, other studies have not found an association between poor COVID-19 outcomes and either HIV status among hospitalized patients (3-5) or HIV-associated factors such as CD4 count, viral load, or type of antiretroviral therapy (ART) (6). The effect of HIV infection on COVID-19 outcomes remains an urgent question in sub-Saharan Africa, where many countries are experiencing dual HIV and COVID-19 epidemics, and capacity to treat severe COVID-19 is limited. Using data from patients with probable or confirmed COVID-19 admitted to specialized treatment centers during March-December 2020 in Zambia, the Zambian Ministry of Health and CDC assessed the relationship between HIV infection and severe COVID-19 and COVID-19-associated death. Among 443 patients included in the study, 122 (28%) were HIV-positive, and of these, 91 (89%) were receiving ART at the time of hospitalization. HIV status alone was not significantly associated with severe COVID-19 at admission or during hospitalization or with COVID-19-associated death. However, among HIV-positive persons, those with severe HIV disease were more likely to develop severe COVID-19 and were at increased risk for COVID-19-associated death. Ensuring that persons maintain HIV disease control, including maintaining ART continuity and adherence, achieving viral suppression, and addressing and managing underlying medical conditions, could help reduce COVID-19-associated morbidity and mortality in sub-Saharan Africa.

Expanding access to HIV services during the COVID-19 pandemic-Nigeria, 2020.

BACKGROUND: To accelerate progress toward the UNAIDS 90-90-90 targets, US Centers for Disease Control and Prevention Nigeria country office (CDC Nigeria) initiated an Antiretroviral Treatment (ART) Surge in 2019 to identify and link 340,000 people living with HIV/AIDS (PLHIV) to ART. Coronavirus disease 2019 (COVID-19) threatened to interrupt ART Surge progress following the detection of the first case in Nigeria in February 2020. To overcome this disruption, CDC Nigeria designed and implemented adapted ART Surge strategies during February-September 2020. METHODS: Adapted ART Surge strategies focused on continuing expansion of HIV services while mitigating COVID-19 transmission. Key strategies included an intensified focus on community-based, rather than facility-based, HIV case-finding; immediate initiation of newly-diagnosed PLHIV on 3-month ART starter packs (first ART dispense of 3 months of ART); expansion of ART distribution through community refill sites; and broadened access to multi-month dispensing (MMD) (3-6 months ART) among PLHIV established in care. State-level weekly data reporting through an Excel-based dashboard and individual PLHIV-level data from the Nigeria National Data Repository facilitated program monitoring. RESULTS: During February-September 2020, the reported number of PLHIV initiating ART per month increased from 11,407 to 25,560, with the proportion found in the community increasing from 59 to 75%. The percentage of newly-identified PLHIV initiating ART with a 3-month ART starter pack increased from 60 to 98%. The percentage of on-time ART refill pick-ups increased from 89 to 100%. The percentage of PLHIV established in care receiving at least 3-month MMD increased from 77 to 93%. Among PLHIV initiating ART, 6-month retention increased from 74 to 92%. CONCLUSIONS: A rapid and flexible HIV program response, focused on reducing facility-based interactions while ensuring delivery of lifesaving ART, was critical in overcoming COVID-19-related service disruptions to expand access to HIV services in Nigeria during the first eight months of the pandemic. High retention on ART among PLHIV initiating treatment indicates immediate MMD in this population may be a sustainable practice. HIV program infrastructure can be leveraged and adapted to respond to the COVID-19 pandemic.

Increase in Antiretroviral Therapy Enrollment Among Persons with HIV Infection During the Lusaka HIV Treatment Surge - Lusaka Province, Zambia, January 2018-June 2019.

Within Zambia, a landlocked country in southern-central Africa, the highest prevalence of human immunodeficiency virus (HIV) infection is in Lusaka Province (population 3.2 million), where approximately 340,000 persons are estimated to be infected (1). The 2016 Zambia Population-based HIV Impact Assessment (ZAMPHIA) estimated the adult HIV prevalence in Lusaka Province to be 15.7%, with a 62.7% viral load suppression rate (HIV-1 RNA <1,000 copies/mL) (2). ZAMPHIA results highlighted remaining treatment gaps in Zambia overall and by subpopulation. In January 2018, Zambia launched the Lusaka Province HIV Treatment Surge (Surge project) to increase enrollment of persons with HIV infection onto antiretroviral therapy (ART). The Zambia Ministry of Health (MoH), CDC, and partners analyzed the U.S. President's Emergency Plan for AIDS Relief (PEPFAR) Monitoring and Evaluation Reporting data set to assess the effectiveness of the first 18 months of the Surge project (January 2018-June 2019). During this period, approximately 100,000 persons with positive test results for HIV began ART. These new ART clients were more likely to be persons aged 15-24 years. In addition, the number of persons with documented viral load suppression doubled from 66,109 to 134,046. Lessons learned from the Surge project, including collaborative leadership, efforts to improve facility-level performance, and innovative strategies to disseminate successful practices, could increase HIV treatment rates in other high-prevalence settings.

Sex Differences in HIV Testing - 20 PEPFAR-Supported Sub-Saharan African Countries, 2019.

Despite progress toward controlling the human immunodeficiency virus (HIV) epidemic, testing gaps remain, particularly among men and young persons in sub-Saharan Africa (1). This observational study used routinely collected programmatic data from 20 African countries reported to the U.S. President's Emergency Plan for AIDS Relief (PEPFAR) from October 2018 to September 2019 to assess HIV testing coverage and case finding among adults (defined as persons aged ≥15 years). Indicators included number of HIV tests conducted, number of HIV-positive test results, and percentage positivity rate. Overall, the majority of countries reported higher HIV case finding among women than among men. However, a slightly higher percentage positivity was recorded among men (4.7%) than among women (4.1%). Provider-initiated counseling and testing (PITC) in health facilities identified approximately two thirds of all new cases, but index testing had the highest percentage positivity in all countries among both sexes. Yields from voluntary counseling and testing (VCT) and mobile testing varied by sex and by country. These findings highlight the need to identify and implement the most efficient strategies for HIV case finding in these countries to close coverage gaps. Strategies might need to be tailored for men who remain underrepresented in the majority of HIV testing programs.

Detection of Typhoidal and Paratyphoidal Salmonella in Blood by Real-time Polymerase Chain Reaction.

BACKGROUND: The gold standard for diagnosis of enteric fever caused by Salmonella Typhi or Salmonella Paratyphi A or B is bone marrow culture. However, because bone marrow aspiration is highly invasive, many hospitals and large health centers perform blood culture instead. As blood culture has several limitations, there is a need for novel typhoid diagnostics with improved sensitivity and more rapid time to detection. METHODS: We developed a clyA-based real-time polymerase chain reaction (qPCR) method to detect Salmonella Typhi and Salmonella Paratyphi A simultaneously in blood. The sensitivity and specificity of this probeset was first evaluated in vitro in the laboratory and then in a typhoid-endemic population, in Karachi, Pakistan, and in healthy US volunteers. RESULTS: We optimized a DNA extraction and real-time PCR-based method that could reliably detect 1 colony-forming unit/mL of Salmonella Typhi. The probe set was able to detect clinical Salmonella Typhi and Salmonella Paratyphi A strains and also diarrheagenic Escherichia coli, but not invasive E. coli or other invasive bacteria. In the field, the clyA qPCR diagnostic was 40% as sensitive as blood culture. However, when qPCR-positive specimens were considered to be true positives, blood culture only exhibited 28.57% sensitivity. Specificity was ≥90% for all comparisons and in the healthy US volunteers. qPCR was significantly faster than blood culture in terms of detection of typhoid and paratyphoid. CONCLUSIONS: Based on lessons learned, we recommend that future field trials of this and other novel diagnostics that detect typhoidal and nontyphoidal Salmonella employ multiple methodologies to define a "positive" sample.

What Does a Performance Measurement System Tell Us About the National Comprehensive Cancer Control Program?

CONTEXT: The National Comprehensive Cancer Control Program (NCCCP) performance measurement system seeks to understand both the processes that funded programs undertake with their respective coalitions to implement the objectives of their cancer plans and the outcomes of those efforts. OBJECTIVE: To identify areas of achievement and technical assistance needs of NCCCP awardees. DESIGN: Program performance was assessed through surveys completed by program directors on performance indicators in 2009 and 2010 and queries from a Web-based management information system in 2011 and 2012. SETTING: Programs funded by the Centers for Disease Control and Prevention's NCCCP. PARTICIPANTS: Sixty-nine programs. MAIN OUTCOME MEASURE(S): The key performance measures assessed were inclusion of diverse partners and key sectors in cancer coalitions, partners' involvement in activities, receiving in-kind resources from partners, using evidence-based interventions and data for setting priorities, conducting program evaluation, using community- or organization-level strategies to address cancer control efforts, and demonstrating progress toward achieving health outcomes. RESULTS: Most programs reported having active coalitions that represent diverse organizational sectors. Nearly all programs routinely assess the burden of cancer. In-kind resources to implement activities peaked at $64 716 in the second year of a 5-year funding cycle and declined in subsequent project years. By year 3, more than 70% of programs reported having an evaluation plan. While programs reported that nearly two-thirds of their interventions were evidence-based, some programs implemented non-evidence-based interventions. A majority of programs successfully used at least 1 community- or organization-level change strategy. However, many programs did not incorporate objectives linked to health outcomes as they reported progress in implementing interventions. CONCLUSIONS: While NCCCP programs were strong at building and maintaining infrastructure, some programs may need additional technical assistance to increase the adoption of evidence-based interventions, develop solid and responsive evaluation plans, and better link efforts to population-based measures that demonstrate impact toward reducing the burden of cancer.

Role clarity and clinical governance: keeping irish hospitals efficient and effective.

The notion of role clarity, and its impact on clinical governance, has not been previously considered within academic literature. The purpose of this research article was to add to theoretical knowledge surrounding the clinical governance and the effect that role clarity has on governance operationally. The context of Irish health care and Irish hospital boards is used to explore this phenomenon. A mixed-methods approach was used to appreciate the central phenomenon. The doctoral dissertation this article was drawn from identified that the adoption of similar or consistent structures and processes between Irish acute care hospitals would aid efficiencies, both human and cost, on multiple levels. Ultimately, the article concludes that role clarity is a significant component in the determination of effective health care. Hospital boards and their individual members should be cognizant of the implications of role clarity and its impact on effective and efficient clinical governance.

Trauma-informed care: keeping mental health settings safe for veterans.

Veterans, as military personnel returning from wars in Afghanistan and Iraq, are frequently coping with various mental health problems. These veterans are at high risk for posttraumatic stress disorder (PTSD) and associated behavioral consequences, including self-harm, verbal and physical aggression, and violence. In this article, we highlight the physiological, physical, and emotional consequences of trauma. We focus on the unique experiences that affect veterans' mental health and associated behaviors and advocate for veterans to receive evidenced-based treatment using trauma-informed and recovery-oriented care.

Mental health issues of women deployed to Iraq and Afghanistan.

The number of women serving in the military and deployed to active-duty is unprecedented in the history of the United States. When women became a permanent sector of the U.S. Armed Services in 1948, their involvement was restricted to comprise only 2% of the military population; today women constitute approximately 14.5% of the 1.4 million active component and 18% of the 850,000 reserve component. Yet, little attention has been paid to the mental health needs of women military members. This review article highlights the history of women in the military and then focuses on the impact of combat exposure and injuries, military sexual trauma, alcohol use, and family separations which are associated with PTSD, depression, suicide, difficulty with reintegration, and homelessness.

Reaching HIV epidemic control in Nigeria using a lower HIV viral load suppression cut-off.

BACKGROUND: Virologic suppression has been defined using a HIV viral load of less than 1000 copies/ml. Low-level viremia (51-999 copies/ml) is associated with an increased risk of virologic failure and HIV drug resistance. METHODS: Retrospective data from persons with HIV (PWH) who initiated ART between January 2016 and September 2022 in Nigeria were analyzed for virologic suppression at cut-off values less than 1000 copies/ml. RESULTS: In 2022, virologic suppression at less than 1000 copies/ml was 95.7%. Using cut-off values of less than 400, less than 200 and less than 50 copies/ml, virologic suppression was 94.2%, 92.5%, and 87%, respectively. DISCUSSION: Monitoring virologic suppression using lower cut-off values, alongside differentiated management of low-level viremia, may help Nigeria achieve HIV epidemic control targets.

Individual and household factors associated with non-disclosure of positive HIV status in a population-based HIV serosurvey.

OBJECTIVES: Non-disclosure of positive HIV status in population-based surveys causes underestimation of national HIV diagnosis and biases inferences about engagement in the care continuum. This study investigated individual and household factors associated with HIV non-disclosure to survey interviewers in Nigeria. DESIGN: Secondary analysis of a cross sectional population-based household HIV survey. METHODS: We analyzed data from adults aged 15-64 years who tested positive for HIV and had antiretroviral drugs (ARVs) in their blood from a nationally representative HIV sero-survey conducted in Nigeria in 2018. We considered ARV use as a proxy for knowledge of HIV diagnosis; thus, respondents who self-reported to be unaware of their HIV status were classified as non-disclosers. We estimated the associations between non-disclosure and various sociodemographic, clinical, and household characteristics using weighted logistic regression. RESULTS: Among 1266 respondents living with HIV who were taking ARVs, 503 (40%) did not disclose their HIV status to interviewers. In multivariable statistical analyses, the adjusted odds of non-disclosure were highest among respondents aged 15-24 years, those with less than a primary school education, and those who were the only person living with HIV in their household. CONCLUSIONS: Non-disclosure of positive HIV status to survey personnel is common among adults who are receiving treatment in Nigeria. These findings highlight the importance of validating self-reported HIV status in surveys using biomarkers of ARV use. Meanwhile, it is crucial to improve disclosure by strengthening interview procedures and tailoring strategies towards groups that are disproportionately likely to underreport HIV diagnoses.

Effect of Test and Treat on clinical outcomes in Nigeria: A national retrospective study.

BACKGROUND: In Nigeria, results from the pilot of the Test and Treat strategy showed higher loss to follow up (LTFU) among people living with HIV compared to before its implementation. The aim of this evaluation was to assess the effects of antiretroviral therapy (ART) initiation within 14 days on LTFU at 12 months and viral suppression. METHODS: We conducted a retrospective cohort study using routinely collected de-identified patient-level data hosted on the Nigeria National Data Repository from 1,007 facilities. The study population included people living with HIV age ≥15. We used multivariable Cox proportional frailty hazard models to assess time to LTFU comparing ART initiation strategy and multivariable log-binomial regression for viral suppression. RESULTS: Overall, 26,937 (38.13%) were LTFU at 12 months. Among individuals initiated within 14 days, 38.4% were LTFU by 12 months compared to 35.4% for individuals initiated >14 days (p<0.001). In the adjusted analysis, individuals who were initiated ≤14 days after HIV diagnosis had a higher hazard of being LTFU (aHR 1.15, 95% CI 1.10-1.20) than individuals initiated after 14 days of HIV diagnosis. Among individuals with viral load results, 86.2% were virally suppressed. The adjusted risk ratio for viral suppression among individuals who were initiated ≤14 days compared to >14 days was not statistically significant. CONCLUSION: LTFU was higher among individuals who were initiated within 14 days compared to greater than 14 days after HIV diagnosis. There was no difference for viral suppression. The provision of early tailored interventions to support newly diagnosed people living may contribute to reducing LTFU.

Assessment of safety and effectiveness of non-neurosurgical management for minimal traumatic brain injury (TBI).

BACKGROUND: Patients with mild traumatic brain injury (TBI) and intracranial hemorrhage often receive neurosurgical consultation. However, only a small proportion of patients require intervention. Our hypothesis is that low-risk minimal TBI patients managed without immediate neurosurgical consultation will have a reasonable safety and effectiveness outcome profile. METHODS: A non-neurosurgical management protocol for adult minimal TBI was implemented at a level I trauma center as an interdisciplinary quality-improvement initiative in November 2018. Minimal TBI was defined as Glasgow Coma Scale (GCS) of 15 secondary to blunt mechanism, without anticoagulant or antiplatelet therapy, and isolated pneumocephalus and/or traumatic subarachnoid hemorrhage on head CT imaging. Safety was assessed by in-hospital mortality, neurosurgical interventions, and ED revisits within two weeks of discharge. Effectiveness was assessed by neurosurgical consult rate and length of stay. Outcomes were compared 8-months pre- and post-protocol implementation. RESULTS: A total of 97 patients were included, of which 49 were pre-protocol and 48 were post-protocol There was no difference in rates of in-hospital mortality [0 (0%) vs 0 (0%)], neurosurgical procedure [1 (2.1%) vs 0 (0%)], operations [0 (0%) vs 0 (0%)], and ED revisits [1 (2.0%) vs 2 (4.2%), p = 0.985] between the periods. There was a significant reduction in neurosurgical consults post-protocol implementation (92% vs 29%, p<0.001). CONCLUSION: A protocol for minimal TBI patients effectively reduced neurosurgical consultation without changes in safety profile. Such an interdisciplinary management protocol for low-risk neurotrauma can effectively utilize the neurosurgery consult services by stratifying neurologically stable TBI patient.

From Paper Files to Web-Based Application for Data-Driven Monitoring of HIV Programs: Nigeria's Journey to a National Data Repository for Decision-Making and Patient Care.

BACKGROUND: Timely and reliable data are crucial for clinical, epidemiologic, and program management decision making. Electronic health information systems provide platforms for managing large longitudinal patient records. Nigeria implemented the National Data Repository (NDR) to create a central data warehouse of all people living with human immunodeficiency virus (PLHIV) while providing useful functionalities to aid decision making at different levels of program implementation. OBJECTIVE: We describe the Nigeria NDR and its development process, including its use for surveillance, research, and national HIV program monitoring toward achieving HIV epidemic control. METHODS: Stakeholder engagement meetings were held in 2013 to gather information on data elements and vocabulary standards for reporting patient-level information, technical infrastructure, human capacity requirements, and information flow. Findings from these meetings guided the development of the NDR. An implementation guide provided common terminologies and data reporting structures for data exchange between the NDR and the electronic medical record (EMR) systems. Data from the EMR were encoded in extensible markup language and sent to the NDR over secure hypertext transfer protocol after going through a series of validation processes. RESULTS: By June 30, 2021, the NDR had up-to-date records of 1,477,064 (94.4%) patients receiving HIV treatment across 1,985 health facilities, of which 1,266,512 (85.7%) patient records had fingerprint template data to support unique patient identification and record linkage to prevent registration of the same patient under different identities. Data from the NDR was used to support HIV program monitoring, case-based surveillance and production of products like the monthly lists of patients who have treatment interruptions and dashboards for monitoring HIV test and start. CONCLUSION: The NDR enabled the availability of reliable and timely data for surveillance, research, and HIV program monitoring to guide program improvements to accelerate progress toward epidemic control.

Peritonitis and technique failure caused by Roseomonas mucosa in an adolescent infected with HIV on continuous cycling peritoneal dialysis.

We report the first case of peritonitis caused by Roseomonas mucosa which led to technique failure in an adolescent patient with HIV receiving peritoneal dialysis. Identification of the causative organism by 16S rRNA gene sequencing and phylogenetic analysis is described.

Functional heterologous expression and purification of a mammalian methyl-CpG binding domain in suitable yield for DNA methylation profiling assays.

DNA methylation is a major epigenetic modification in mammalian cells, and patterns involving methylation of cytosine bases, known as CpG methylation, have been implicated in the development of many types of cancer. Methyl binding domains (MBDs) excised from larger mammalian methyl-CpG-binding proteins specifically recognize methyl-cytosine bases of CpG dinucleotides in duplex DNA. Previous molecular diagnostic studies involving MBDs have employed Escherichia coli for protein expression with either low soluble yields or the use of time-consuming denaturation-renaturation purification procedures to improve yields. Efficient MBD-based diagnostics require expression and purification methods that maximize protein yield and minimize time and resource expenditure. This study is a systematic optimization analysis of MBD expression using both SDS-PAGE and microscopy and it provides a comparison of protein yield from published procedures to that from the conditions found to be optimal in these experiments. Protein binding activity and specificity were verified using a DNA electrophoretic mobility shift assay, and final protein yield was improved from the starting conditions by a factor of 65 with a simple, single-step purification.

Redesigning a graduate research course for evidence-based competencies.

Nursing research is critical to establish the science for the discipline and to provide a foundation for evidence-based practice. All nurses need to understand the research process and engage in research at the level for which they were prepared. The American Association of Colleges of Nursing has clearly outlined essential learning outcomes for each level of nursing education, including the competent application of research findings to clinical problems. This article describes the evolution of a graduate-level research course to provide master's level students with a sound foundational understanding of the research process, the innovation undertaken to address identified learning needs, and the important lessons learned.

A national HIV clinical mentorship program: Enabling Zambia to accelerate control of the HIV epidemic.

Although Zambia has increased the proportion of people living with HIV (PLHIV) who are on antiretroviral therapy (ART) in recent years, progress toward HIV epidemic control remains inconsistent. Some districts are still failing to meet the UNAIDS 90/90/90 targets where 90% of PLHIV should know their status, 90% of those diagnosed should be on ART, and 90% of those on ART should achieve viral load suppression (VLS) by 2020. Providing consistently excellent HIV services at all ART health facilities is critical for achieving the UNAIDS 90/90/90 targets and controlling the HIV epidemic in Zambia. Zambia Ministry of Health, in collaboration with the U.S. Centers for Disease Control and Prevention (CDC), aimed to achieve these targets through establishing a national HIV clinical mentorship program in which government-employed mentors were assigned to specific facilities with a mandate to identify and ameliorate programmatic challenges. Mentors were hired, trained and deployed to individual facilities in four provinces to mentor staff on quality HIV clinical and program management. The pre-mentorship period was July 2018-September 2018 and the post-mentorship period was July 2019-September 2019. Review of key programmatic indicators from the pre and post-deployment periods revealed the proportion of people who had a positive HIV test result out of those tested increased from 4.2% to 6.8% (P <0.001) as fewer HIV tests were needed despite the number of PLHIV being identified and placed on ART increasing from 492,613 to 521,775, and VLS increased from 84.8% to 90.1% (p <0.001). Key considerations in the establishment of an HIV clinical mentorship program include having a government-led process of regular site level data review and continuous clinical mentorship underpinned by quality improvement methodology.
