RESUMO

(1) Background: There is growing concern in South Africa about risky sexual behaviour, sexual transmitted infections (STIs), and unplanned pregnancy among young people. Many sexually active students engage in several risky behaviours, including sex with multiple sexual partners, low condom use, and low contraceptive use. This paper qualitatively explores factors influencing non-use of sexual reproductive health services by students at Mangosuthu University of Technology in South Africa (MUT). (2) Methods: Data was collected through 20 in-depth interviews with MUT students and subjected to inductive thematic analysis. Informed consent was obtained before all data collection. (3) Results: The main themes identified were risky sexual behaviours translating to multiple intimate partners, perceived quality of condom use, perceived benefits of contraceptives, negotiating safer sex with partners, developing a greater sense of autonomy, alcohol and drug abuse, perceived benefits of health education provided by the MUT, and lack of open communication. (4) Conclusions: The findings suggest that university students need multi-faceted interventions designed to address challenges with risky sexual behaviours including knowledge and benefits of condom and contraceptive use to prevent STIs and unwanted pregnancies, as well as providing psychosocial interventions to support these students' autonomy.

RESUMO

Adolescents living with HIV (ALHIV) struggle to remain engaged in HIV-related care and adhere to antiretroviral treatment (ART) due to a myriad of physical, psychological and cognitive-developmental challenges. We report on the profile of ALHIV aged 10-19 years on ART and the clinical factors associated with their retention in care. A retrospective cohort analysis was conducted with 16,108 ALHIV, aged 10-19 years, who were enrolled in 136 ART clinics in the Ehlanzeni district. Anonymised data were obtained from electronic medical records (Tier.net). Trends in retention in care among adolescents on ART was described using Kaplan-Meier survival estimates. Cox proportional analysis was performed to identify factors associated with retention in care over 2 years. More than half (53%) were females, and median duration on ART was 8 months. Retention in care among adolescents at months 6, 12, 18 and 24 was 90.5%, 85.4%, 80.8% and 76.2%, respectively. After controlling for confounders, risk of dying or lost to follow up increased for female adolescents (aHR = 1.28, 95% CI 1.10-1.49); being initiated on ART while pregnant (aHR = 2.72, 95% CI 1.99-3.69); history of TB infection (aHR = 1.71, 95% CI 1.10-2.65); and started ART at age 10-14 years (aHR = 2.45, 95% CI 1.96-3.05), and 15-19 years (aHR = 9.67, 95% CI 7.25-12.89). Retention in care among adolescents on ART over two-year period was considerably lower than the UNAIDS 2030 target of 95%. Of particular concern for intervention is the lower rates of retention in care among females and pregnant adolescents and starting ART between the ages of 10 and 19 years. Family or caregivers and peer support groups centred interventions designed to promote early initiation and retention in care through early case identification are needed.

RESUMO

(1) Background: Psychosocial support (PSS) plays a significant role in persistent adherence to and retention in antiretroviral therapy (ART) for adolescents living with the human immunodeficiency virus (ALHIV). This paper qualitatively explores the experiences of ALHIV on ART, who participated in a PSS programme in five public primary healthcare facilities in Mpumalanga Province in South Africa during the COVID-19 pandemic. (2) Methods: Data were collected through 24 focus group discussions with 173 ALHIV on ART and subjected to inductive thematic analysis. Informed consent was obtained before all data collection. (3) Results: The PSS programme facilitated the process of full HIV disclosure to these adolescents with the support of parents/guardians while motivating adherence through peer support groups and health education for improved treatment literacy. Participants reported positive health systems experiences, improved healthcare provider-client relations, and prompt access to health services. (4) Conclusions: The PSS programme successfully kept ALHIV engaged in ART care despite the health service disruptions encountered during the COVID-19 pandemic. We recommend rigorous evaluation of the effects of the PSS intervention on adherence to and retention in ART among ALHIV in HIV-endemic settings.

RESUMO

Adolescents living with HIV (ALHIV) need support from family, peers and health workers to remain on antiretroviral therapy and achieve and sustain viral suppression. This paper qualitatively explores the implementation of a psychosocial support intervention (PSS) in five primary health care facilities in the Ehlanzeni district, South Africa. Data were collected through key informant interviews and focus group discussions with ALHIV on ART. Data analysis employed inductive thematic analysis. Informed consent was obtained prior to all data collection. The PSS intervention facilitated full disclosure of HIV status to adolescents, supported treatment adherence through health education, peer support, health care provider- and client relations, and quick access to health service delivery. However, COVID-19 restrictions and regulations challenged the implementation of the intervention. The PSS intervention showed promise to support adolescent's adherence and retention in care. We recommend innovative approaches to account for systemic disruptions, as evidenced by the COVID-19 pandemic.

RESUMO

In May 2022, monkeypox virus (MPXV) outbreak was confirmed amid the coronavirus disease 2019 (COVID-19) pandemic in many parts of the world including Africa. This is the largest outbreak since monkeypox (MPX) was first detected in humans in 1970. The MPX outbreak in Africa is an added burden to the fragile healthcare systems that are already overburdened with several reoccurring epidemics. Although several efforts are in place to effectively contained the outbreak. Several measures such as improved surveillance and diagnostic are necessary to contain the spread of the disease in Africa. This commentary highlights the challenges with the MPX outbreak in Africa and discusses the measures that can be taken to limit the spread of the disease, particularly in high-risk countries.

RESUMO

Adolescents (10 to 19 years) living with HIV (ALHIV) experience disproportionately poor adherence to antiretroviral treatment (ART) compared to other age groups. Several barriers, including psychosocial challenges, contribute to this observation. Psychosocial support (PSS) interventions show promising results as a strategy to deal with the biological and psychosocial challenges faced by ALHIV. However, there is dearth of information on how psychosocial support interventions designed to improve treatment adherence and retention in care among ALHIV are effective. In this commentary, we used the biopsychosocial model to formulate hypotheses on how the components of a PSS intervention could improve adherence and retention in ART care. Psychological wellbeing, coping strategies, social support, self-efficacy, and disclosure are key components in the intervention designed to improve ART adherence and retention in care. The management of ALHIV for improved ART adherence and retention requires recognising and addressing the complex biological, psychological and social issues peculiar to them.

RESUMO

In August 2021, the Marburg virus disease (MVD) outbreak was confirmed amid the coronavirus disease 2019 (COVID-19) pandemic in the Republic of Guinea. This is the first time it is detected in Guinea and West Africa. Marburg virus is one of the world's most threatening diseases, causing severe haemorrhagic fever, with a case fatality rate of 90%. Currently, there are no vaccines and specific antiviral drugs for MVD. Technical teams and community health care workers that were set up as part of the recent Ebola virus disease (EVD) outbreak that was declared over on June 19, 2021, are now redeployed to support governments response activities of the MVD outbreak in the country. The MVD is an added burden to the fragile healthcare systems that are already overburdened with multiple reoccurring epidemics and the COVID-19 pandemic. Previous epidermic strategies are needed to contain the spread of the disease, amid the COVID-19 pandemic, so the health care systems are not overwhelmed. This commentary discusses the available evidence regarding the epidemic of MVD in Guinea amid the COVID-19 pandemic, and highlights the efforts, challenges to be prioritized, and provides evidence-based recommendations.

RESUMO

BACKGROUND: Achieving undetectable viral load is crucial for the reduction of HIV transmissions, AIDS-related illnesses and death. Adolescents (10 to19 years) living with HIV (ALHIV) on antiretroviral treatment (ART) have worse treatment adherence and lower viral suppression rates compared to adults. We report on the clinical factors associated with viral suppression among ALHIV in the Ehlanzeni district, Mpumalanga in South Africa. METHODS: A cross-sectional analysis was conducted with 9386 ALHIV, aged 10 to 19 years, who were enrolled in 136 ART clinics in the Ehlanzeni district. Clinical and immunological data were obtained from electronic medical records (Tier.net). ALHIV were categorised as having achieved viral suppression if their latest viral load count was < 1000 ribonucleic acid (RNA) copies/mL. Using a backward stepwise approach, a multivariate logistic regression analysis was performed to identify factors independently associated with viral suppression. RESULTS: The mean age of the participants was 14.75 years (SD = 2.9), and 55.43% were female. Mean duration on ART was 72.26 (SD = 42.3) months. Of the 9386 adolescents with viral load results recorded, 74% had achieved viral suppression. After adjusting for other covariates, the likelihood of achieving viral suppression remained significantly higher among ALHIV who were: female (AOR = 1.21, 95% CI 1.05-1.39), and had most recent CD4 count > 200 (AOR = 2.53, 95% CI 2.06-3.11). Furthermore, the likelihood of having viral suppression was lower among adolescents with CD4 count > 200 at baseline (AOR = 0.73, 95% CI 0.61-0.87), and who were switched to second line regimen (AOR = 0.41, 95% CI 0.34-0.49). CONCLUSIONS: Viral suppression amongst ALHIV at 74% is considerably lower than the WHO target of 95%. Of particular concern for intervention is the lower rates of viral suppression amongst male ALHIV. Greater emphasis should be placed to early enrolment of ALHIV on ART and keeping them engaged in care (beyond 6 months). Furthermore, improved and regular viral load monitoring will help to adequately identify and manage ALHIV with unsuppressed viral load and subsequently switching to second line treatment.

RESUMO

BACKGROUND: Cervical cancer is the fourth leading oncological cause of death in women. Variable trends in cervical cancer mortality have been observed across Europe, despite the widespread adoption of screening programs. This variability has previously been attributed to heterogeneity in the quality of screening programs. METHODS: Age-standardized cervical cancer death rates for European countries between 1985 and 2014 were analyzed using Joinpoint regression. Countries were dichotomized based on year of implementation and population invitational coverage of national population-based cervical cancer screening programs. National cervical cancer mortality trends during the study period were compared based on this classification. RESULTS: Decreasing trends in mortality were observed in all European countries with the specific exceptions of Bulgaria, Greece and Latvia. The highest rates of cervical cancer mortality throughout the study period were in Romania (16.0-14.9/100,000) and the lowest rates in Italy (1.4-1.2/100,000). The greatest percentage decline in mortality was observed in the United Kingdom and the greatest absolute reduction in mortality was seen in Hungary. European countries which implemented a national population-based cervical cancer screening program prior to 2009 demonstrated greater improvements in cervical cancer mortality outcomes compared to those that did not (p = 0.016). CONCLUSION: Cervical cancer mortality is improving in most European countries; however, substantial variation remains. Trends in mortality were associated with the time of implementation of national population-based cervical screening programs.

RESUMO

The SARS-CoV-2 infection, which causes the COVID-19 disease, has impacted every nation on the globe, albeit disproportionately. African countries have seen lower infection and mortality rates than most countries in the Americas Europe and Asia. In this commentary, we explore some of the factors purported to be responsible for the low COVID-19 infection and case fatality rates in Africa: low testing rate, poor documentation of cause of death, younger age population, good vitamin D status as a result of exposure to sunlight, cross-immunity from other viruses including coronaviruses, and lessons learnt from other infectious diseases such as HIV and Ebola. With the advent of a new variant of COVID-19 and inadequate roll-out of vaccines, an innovative and efficient response is needed to ramp up testing, contact tracing and accurate reporting of infection rates and cause of death in order to mitigate the spread of the infection.

RESUMO

BACKGROUND: Mental health disorders such as high levels of anxiety, isolation, depression and suicide ideation reported among young people living with HIV (10-24 years;YPLHIV) contribute significantly to poor medication adherence and retention in care. While there is evidence supporting the role of psychosocial support interventions in promoting adherence and retention in antiretroviral treatment (ART) among adults living with HIV, there is little evidence on the role of psychosocial support on medication adherence among YPLHIV. This scoping review was designed to identify and classify the types and effects of psychosocial support interventions designed to improve adherence and retention in ART among YPLHIV globally. METHOD: We searched six electronic databases (i.e., Scopus, Pubmed and EBSCOHost (Academic Search Premier, CINAHL, Psycarticles and Medline). Six relevant articles published between 2011 and 2019 met our inclusion criteria. We extracted information relevant to the nature and outcomes of the reported interventions using thematic content analysis informed by the Population, Intervention, comparison, outcome, and time (PICOT) framework. RESULTS: Four distinctive treatment modalities that focused on improving ART adherence and retention in care were identified: individual counselling, support groups, family-centered services, and treatment supporters. CONCLUSION: There is a dearth of psychosocial support interventions to improve adherence and retention in ART amongst adolescents and young adults living with HIV. Future research and programming should seek to address psychosocial support interventions or approaches specifically designed to address the needs of YPLHIV.

RESUMO

Literature suggests that psychosocial support programmes can improve wellbeing and mental health among learners. There is however limited documentation on methodologies and factors that shape integration of such programmes within the education sector. This qualitative study aimed to contribute towards addressing this knowledge gap by analysing the implementation process of the Mainstreaming of Psychosocial Support in the Education Sector programme in Zambia. The study showed that the programme contributed to improved school culture and learning involvement. This transformation led to reduction in school dropout, as well as improved students' wellbeing and performance. These positive results motivated Zambia and other countries to integrate psychosocial support into the education systems. Community engagement, outreach activities, group forums and partnerships were the key programme methodologies that facilitated the integration process. However, limited stakeholder involvement in developing the monitoring process complicated the integration process in the initial stages. In conclusion, effectively facilitating programme integration requires ensuring that the programme is credible, inclusive and has clear implementation guidelines.

RESUMO

Microglia are the resident macrophage and immune cell of the brain and are critically involved in combating disease and assaults on the brain. Virtually all brain pathologies are accompanied by acidosis of the interstitial fluid, meaning that microglia are exposed to an acidic environment. However, little is known about how extracellular acidosis impacts on microglial function. The activity of microglia is tightly controlled by 'on' and 'off' signals, the presence or absence of which results in generation of distinct phenotypes in microglia. Activation of G protein coupled purinergic (P2Y) receptors triggers a number of distinct behaviours in microglia, including activation, migration, and phagocytosis. Using pharmacological tools and fluorescence imaging of the murine cerebellar microglia cell line C8B4, we show that extracellular acidosis interferes with P2Y receptor-mediated Ca(2+) signalling in these cells. Distinct P2Y receptors give rise to signature intracellular Ca(2+) signals, and Ca(2+) release from stores and Ca(2+) influx are differentially affected by acidotic conditions: Ca(2+) release is virtually unaffected, whereas Ca(2+) influx, mediated at least in part by store-operated Ca(2+) channels, is profoundly inhibited. Furthermore, P2Y1 and P2Y6-mediated stimulation of migration is inhibited under conditions of extracellular acidosis, whereas basal migration independent of P2Y receptor activation is not. Taken together, our results demonstrate that an acidic microenvironment impacts on P2Y receptor-mediated Ca(2+) signalling, thereby influencing microglial responses and responsiveness to extracellular signals. This may result in altered behaviour of microglia under pathological conditions compared with microglial responses in healthy tissue.
