RESUMEN

People living with HIV (PLWH) are at higher risk of reactivation of Chagas disease, a neglected tropical disease, caused by Trypanosoma cruzi. There are no data from UK HIV clinics on the prevalence of T. cruzi. We implemented T. cruzi screening at our clinic as part of routine care for PLWH with epidemiological risk factors. Among 86 patients screened, none had positive serology: one seropositive patient was identified due to increased clinician awareness. Implementing T. cruzi screening as part of routine clinical care was feasible, though labour intensive and identified at-risk individuals.

RESUMEN

Comprehensive sexual education (CSE) is an important approach for health promotion dissemination in schools, particularly when delivered in participatory ways that are sport based, peer or near-peer led, and include concepts of gender and power dynamics. Sufficient attendance at CSE sessions is critical to ensure content exposure and build potential for impact. This article details implementation lessons from the delivery of an after-school, near-peer-led CSE program called SKILLZ during a cluster randomized controlled trial among 40 secondary schools in Cape Town, South Africa. SKILLZ is an evidence-based program previously implemented in similar contexts. Attendance in this study was suboptimal (less than 50%) despite qualitative indications of high acceptability and extensive efforts to adapt implementation and boost attendance. Qualitative and quantitative data gathered during anonymous surveys, in-depth interviews, and focus group discussions with participants with high and low attendance records, near-peer coaches, and school staff from both cohorts indicated that poor attendance could be attributed to several factors. Program adaptations, such as delivering difficult-to-access health services before participants attended the SKILLZ program rather than after, may have reduced the incentive for young people to attend the program. Practical barriers to attendance were identified, including security concerns, competing priorities, and unfamiliarity with after-school programming culture in this setting. Community engagement and acceptability of sexual education programs for adolescents alone may be insufficient to ensure program uptake and engagement.

RESUMEN

South African secondary schools do not deliver school-based healthcare services despite high rates of human immunodeficiency virus (HIV) infection, sexually transmitted infections, and unplanned pregnancies among adolescents, ongoing sub-optimal uptake of healthcare services from public healthcare facilities by adolescents, and national policy support for such services. A pilot school health nursing programme (SHNP) was offered to 44 secondary schools in a single health sub-district within the Western Cape, South Africa. The programme included fortnightly nurse visits that offered a standard package of healthcare services, including sexual and reproductive health services tailored according to school preference.Of the 44 schools, 42 gave permission for the SHNP to operate, with the majority of schools selecting the full comprehensive package of services. Programme implementation was truncated such that delivery only occurred over two school terms (20 weeks); however, 344 students attended the service. The majority of service users were female with a median age of 16 years, and over a half attended the service for sexual and reproductive health services.Contribution: A key challenge to school-based health service delivery arose from inadequate stakeholder support and differential views of adolescent healthcare needs among government officials, parents, guardians, school staff and governing bodies. These findings motivate for ongoing multi-level stakeholder engagement around the reality of adolescent healthcare needs and further opportunities to deliver school health services for longer time periods such that their feasibility, acceptability, and potential to impact healthcare outcomes can be assessed in this setting.

RESUMEN

BACKGROUND: Modified Release (MR) orally administered drugs products [Extended-Release (ER) and Delayed-Release (DR)] differ from Immediate-Release (IR) drug products in their drug release site and/or rate to offer therapeutic advantages. It is important to understand the biopharmaceutics factors that determine how a drug works in the gastrointestinal tract and the various pharmacokinetic properties that determine a drug's rate of absorption and release in the human body. To better understand the biopharmaceutics characteristics of ER and DR drug products, this study retrospectively analyzed submissions approved by the US Food and Drug Administration (FDA), from 2001 to 2021, and their corresponding review documents. This review work is expected to enhance the readers' understanding regarding the biopharmaceutics properties that supported approval of these products' ER claims, as per 21 CFR 320.25(f), and DR claims. METHODS: A comprehensive search was conducted using the FDA's internal New Drug Application (NDA) database for ER and DR oral drug products approved between 2001 and 2021. The search yielded 87 ER applications (23 ER capsules and 64 ER tablets) and 21 DR applications (10 DR capsules, 11 DR tablets) for which electronic records were accessible. These products were analyzed for overall drug product design, dosing frequency compared to the reference (if applicable), degree of fluctuation, dissolution method, and alcohol dose-dumping. RESULTS: Out of 87 total applications for ER drug products that were assessed, 62% of the ER tablets contained a polymer matrix formulation, and hypromellose (HPMC) was used in 50% of these products. 52% of the ER capsules consisted of polymer beads while about half of the DR drug products contained a non-bead formulation with a combination of polymers. The majority of ER drug products were found to have a reduction in dosing frequency and a decrease in the degree of fluctuation when compared to the IR reference product. The 13 ER drug products that exhibited an increase in degree of fluctuation exhibited general and pharmacodynamic benefits, such as reduced dosing frequency and reduced pill burden. The majority of DR formulations were developed to prevent drug degradation in the stomach, followed by to decrease potential stomach irritation, and lastly for localized release in the colon. The majority of ER drug products had 1:1 ratios of dissolution duration compared to dosing frequency (i.e., the majority of ER drug products had a dissolution duration of 24 h and were dosed every 24 h while those with a dissolution duration of 12 h were dosed every 12 h). The majority of ER applications had single-stage dissolution methods while most DR drug products used biphasic dissolution methods. All of the DR dissolution methods incorporated an acid stage of 2 h and a buffer stage with various timeframes. 53% the DR drug products had a ratio of dissolution duration to dosing frequency of 1:4 (e.g. a dissolution duration of 2 h to a dosing frequency of 8 h) or 1:8 (e.g. a dissolution duration of 2 h to a dosing frequency of 16 h). Of the ER tablets and DR drug products, 72% exhibited no alcohol dose-dumping under in vitro testing conditions. ER capsules, however, did not yield similar results-most of which exhibited alcohol induced dose-dumping. Alcohol dose dumping was mitigated by either in vivo studies or warnings on the drug product label. CONCLUSION: The results of this study help the reader understand the design, characteristics, and pharmacological advantages of the ER and DR drug products for patient benefit; as well as the regulations governing the FDA's assessment of ER claims.

RESUMEN

BACKGROUND: HIV remains a leading contributor to the disease burden in sub-Saharan Africa, with adolescents and young people disproportionately affected. Optimising pre-exposure prophylaxis (PrEP) uptake has predominantly focused on women and adult men who have sex with men. We explore adolescent boys and young men's PrEP uptake preferences in South Africa, Uganda, and Zimbabwe. METHODS: A cross-sectional sequential exploratory mixed-methods study amongst males aged 13-24 years was conducted between April and September 2019 as part of the CHAPS trial. Group discussions (GDs) and In-Depth Interviews (IDIs) focused on motivations and hindrances for HIV testing, PrEP preference, and reasons for the uptake of PrEP. A thematic approach was used to analyse the qualitative data. A quantitative survey following the qualitative work covered questions on demographics, HIV risk and PrEP preferences (on-demand vs. daily). For quantitative analysis, we fitted logistic regression models to determine factors associated with on-demand vs daily PrEP preference. RESULTS: Overall, 647 adolescent boys and young men (median age 20, IQR: 17-22) were enrolled. Of these, 422 (65.22%) preferred on-demand PrEP (South Africa 45.45%, Uganda 76.80%, Zimbabwe 70.35%; p<0.001). Factors independently associated with on-demand PrEP included country (South Africa, adjusted odds ratio (aOR) = 0.19 [95%CI:0.1-0.3] compared to Uganda) and advanced planning of sex [>24 hours in advance aOR = 1.4 (0.9-2.3) compared to <2 hours]. Qualitatively, participants commonly believed they were not at risk of HIV acquisition most of the time and thought that on-demand PrEP would be suitable as they tend to plan sexual activity in advance. CONCLUSION: Preference for on-demand PrEP is high in young males. The qualitative data support a preference for on-demand PrEP in those who plan sex in advance. HIV intervention programs should offer both on-demand and daily PrEP to engage more adolescent boys and young men in HIV prevention practices.

RESUMEN

Limited information is available regarding the efficacy of antiretrovirals in people with HIV-1 and high or very high Body Mass Index (BMI). This is especially the case for the alafenamide salt of tenofovir as clinical trials have only enrolled patients with BMI ≤30 kg/m2. Lower concentrations of some antiretrovirals are expected in patients with BMI >30 kg/m2 due to potential changes in clearance and distribution of medication. This report describes an individual taking tenofovir alafenamide, emtricitabine and efavirenz in whom HIV-1 viral load was consistently undetectable (<50 copies/ml) over a 2.5 year period. During this period the patient's BMI ranged between 59.8 and 68.1 kg/m2. Further data is required to support the efficacy of antiretrovirals in individuals with high and very high BMI.

RESUMEN

DNA glycosylases protect genetic fidelity during DNA replication by removing potentially mutagenic chemically damaged DNA bases. Bacterial Lhr proteins are well-characterized DNA repair helicases that are fused to additional 600-700 amino acids of unknown function, but with structural homology to SecB chaperones and AlkZ DNA glycosylases. Here, we identify that Escherichia coli Lhr is a uracil-DNA glycosylase (UDG) that depends on an active site aspartic acid residue. We show that the Lhr DNA helicase activity is functionally independent of the UDG activity, but that the helicase domains are required for fully active UDG activity. Consistent with UDG activity, deletion of lhr from the E. coli chromosome sensitized cells to oxidative stress that triggers cytosine deamination to uracil. The ability of Lhr to translocate single-stranded DNA and remove uracil bases suggests a surveillance role to seek and remove potentially mutagenic base changes during replication stress.

RESUMEN

BACKGROUND: Adolescents in sub-Saharan Africa (SSA) remain vulnerable to HIV infection. While pre-exposure prophylaxis (PrEP) is highly effective in preventing HIV transmission as a daily or on-demand regimen, tailored approaches are necessary. The Combined HIV Adolescent PrEP and Prevention Study (CHAPS) is a mixed-methods research program investigating the acceptability and feasibility of implementing daily and on-demand PrEP among young people in SSA. It also aims to determine an on-demand dosing schedule for insertive sex. For this paper, we explored preferences for daily versus on-demand PrEP amongst adolescents as part of CHAPS. METHODS: Purposive sampling was used to recruit participants from Soweto and Cape Town (South Africa), Wakiso district (Uganda) and Chitungwiza (Zimbabwe). At the time of the study in 2018/2019, Uganda had not rolled out PrEP to the general population; in Zimbabwe, PrEP for young people was only available at selected sites with one located within the study recruitment area. In South Africa, PrEP was made available to selected high-risk groups. We conducted 60 in-depth interviews and 24 group discussions amongst young people aged 13-24 without HIV in South Africa, Uganda, and Zimbabwe. All in-depth interviews and group discussions were audio-recorded, transcribed verbatim and translated to English. Data were analysed using framework analysis. The main themes were centered around preferences for daily and on-demand PrEP. RESULTS: Reasons for on-demand preferences included stigma, pill fatigue, adherence and side effects. Reasons for daily PrEP preferences included factors related to sexual risk behaviour, continuous protection against incidents of unintentional exposure, and the increased efficacy of a daily dose. Participants at all sites preferring daily PrEP identified the same reasons, with more males than females citing inadvertent blood contact or perceived increased efficacy. Similarly, participants at all sites preferring on-demand PrEP gave the same reasons for their preferences for on-demand PrEP; the exception was South Africans who did not mention the hope of having fewer side effects by not taking daily PrEP. Additionally, more males than females cited intermittent sex as a reason for opting for on-demand PrEP. CONCLUSIONS: Our study is the first known to explore and describe youth preferences for daily versus on-demand PrEP. While the choice is clear-cut, the reasons cited in the different options provide invaluable insights into their decisions, and the actual and perceived facilitators and barriers to access to PrEP. Further education is needed amongst young people, not only about PrEP but also in other areas of comprehensive sexuality education. Exploring all options of HIV prevention is crucial to provide a tailored, one-size-does-not-fit-all approach to adolescent care in SSA to reduce and, the continued and increasing risk of this preventable infection.

RESUMEN

Engagement of adolescents and young adults (AYA) in HIV research is increasing in many settings. We organized a crowdsourcing open call to solicit examples of how AYA have been engaged in HIV research in Africa and to develop an engagement typology. We formed a steering committee, promoted the open call, organized judging and recognized finalists. We used a multi-methods approach to identify emerging themes and measure engagement. We received 95 entries from individuals in 15 countries; 74 met the eligibility criteria. More than three-quarters of entries were from AYA (55/74, 74%). Four themes characterized AYA engagement: (1) AYA were co-creators in the HIV research process. (2) AYA were involved in community-level capacity building. (3) AYA were co-leaders in minor risk research. (4) AYA used digital methods to enhance engagement. Our open call identified diverse methods of AYA engagement, which can enhance strategies used to reach AYA in African HIV studies.

RESUMEN

BACKGROUND: Monitoring oxygen saturation in shocked patients is a challenging nursing procedure. Shock syndrome alters peripheral tissue perfusion and hinders peripheral capillary oxygen saturation (SpO2) measurements. Our study aimed to find a solution to this problem. The pharynx is expected to be an accurate SpO2 measurement site in shocked patients. We clinically evaluated the pharyngeal SpO2 measurements against the arterial oxygen saturation (SaO2) measurements. METHODS: A prospective cohort research design was used. This study included 168 adult shocked patients. They were admitted to five intensive care units from March to December 2020 in an Egyptian hospital. A wrap oximeter sensor was attached to the posterior surface of an oropharyngeal airway (OPA) by adhesive tape. The optical component of the sensor adhered to the pharyngeal surface after the OPA insertion. Simultaneous pharyngeal peripheral capillary oxygen saturation (SpO2) and arterial oxygen saturation (SaO2) measurements were recorded. The pharyngeal SpO2 was clinically evaluated. Also, variables associated with the SpO2 bias were evaluated for their association with the pharyngeal SpO2 bias. RESULTS: The pharyngeal SpO2 bias was - 0.44% with - 1.65 to 0.78% limits of agreement. The precision was 0.62, and the accuracy was 0.05. The sensitivity to detect mild and severe hypoxemia was 100%, while specificity to minimize false alarm of hypoxemia was 100% for mild hypoxemia and 99.4% for severe hypoxemia. None of the studied variables were significantly associated with the pharyngeal SpO2 bias. CONCLUSION: The pharyngeal SpO2 has a clinically acceptable bias, which is less than 0.5% with high precision, which is less than 2%.

RESUMEN

Background and Objective: Sickle Cell Disease (SCD) is known to cause acute severe pain episodes known as vaso-occlusive crisis (VOC) mainly treated with opioid analgesics. Since the opioid epidemic there is an interest in determining the opioid misuse potential in these patients. Therefore, the primary objective of this study is to determine the rates of opioid misuse among patients with SCD by assessing the rate of unexpected drug screening results in a sickle cell disease clinic. Methods: This was a retrospective chart review study conducted at the outpatient sickle cell disease clinic. The primary independent variables were the prescribed opioid medications while the primary dependent variable was the collected opioid metabolite. Descriptive statistics, linear regression and multivariate logistic regression analysis were conducted using SPSS version 24. Results: A total of 100 participants were recruited from July 1, 2018, to June 30, 2020 with 71 included in the analysis. The total mean of morphine milligram equivalents (MME) for all participants was 71.1±104.9 with 71% of participants having a daily calculated MME of <90MME. The odds of misusing an opioid were 6.72 times higher (P<.02) if a participant used marijuana compared to a participant who didn't. In addition, the odds of misusing an opioid were 2.47 times higher (P<.04) if the patient was prescribed an opioid daily dose greater than 90 MME as opposed to a daily dose less than 90 MME. Conclusion: Participants who consumed greater than 90 MME's per day and utilized marijuana were more likely to misuse opioids.

RESUMEN

INTRODUCTION: Sub-Saharan Africa (SSA) carries the burden of the HIV epidemic, especially among adolescents and young people (AYP). Little is known about pre-exposure prophylaxis (PrEP) uptake and preferences among AYP in SSA. We describe preferences for daily and on-demand PrEP among AYP in South Africa, Uganda and Zimbabwe. METHODS: A cross-sectional survey was conducted in 2019 among 13- to 24-year olds, capturing socio-demographics, HIV risk behaviours and preferences for daily or on-demand PrEP. Logistic regression models were used to estimate odds ratios, adjusting for site, sex and age. RESULTS AND DISCUSSION: A total of 1330 participants from Cape Town (n = 239), Johannesburg (n = 200), Entebbe (n = 491) and Chitungwiza (n = 400) were enrolled; 673 (51%) were male, and the median age was 19 years (interquartile range 17-22 years). Of 1287 participants expressing a preference, 60% indicated a preference for on-demand PrEP with differences by site (p < 0.001), sex (p < 0.001) and age group (p = 0.003). On-demand PrEP was most preferred in Entebbe (75%), among males (65%) versus females (54%) and in older participants (62% in 18- to 24-year-olds vs. 47% in 13- to 15-year-olds). After adjusting for site, sex and age group, preference for on-demand PrEP decreased as sex frequency over the past month increased (p-trend = 0.004) and varied with the number of partners in the last 6 months, being least popular among those reporting four or more partners (p = 0.02). Participants knowing further in advance that they were likely to have sex were more likely to prefer on-demand PrEP (p-trend = 0.02). Participants having a larger age gap with their most recent partner and participants whose last partner was a transactional sex partner or client were both less likely to prefer on-demand compared to daily PrEP (p = 0.05 and p = 0.09, respectively). Participants who knew their most recent partner was living with HIV or who did not know the HIV status of their most recent partner were less likely to prefer on-demand PrEP (p = 0.05). CONCLUSIONS: Our data show that AYP in four SSA communities prefer on-demand over daily PrEP options, with differences seen by site, age and sex. PrEP demand creation needs to be reviewed, optimized and tailored to socio-demographic differences and designed in conjunction with AYP.

RESUMEN

In order to respond more effectively to the health of young people in South Africa, in 2017 the National Department of Health of South Africa released the National Adolescent & Youth Health Policy. The Policy focused on a range of health problems and recommended interventions for delivery through multiple settings and government departments. It also included specific recommendations to empower and involve young people in policy and programme implementation. Adaptation of a short course on adolescent health in lowand middle-income countries, organized annually by the London School of Hygiene and Tropical Medicine and the World Health Organization, was piloted in 2017 as one means of contributing to the implementation of the Policy. The Adolescent & Youth Health Policy short course was subsequently offered in 2018 and 2019, attracting 96 participants working on adolescent health in various organizations at national and provincial levels throughout the country. Most participants (75%) successfully completed the course, as assessed by the completion criteria that had been defined. The range of topics for the assignments selected by the participants over the 3 years reflected both the content and intent of the Policy. The evaluations of the short course indicate that it helped to create legitimacy and strengthen the capacity of various constituencies, both of which are important prerequisites for policy implementation.

RESUMEN

Pre-exposure prophylaxis (PrEP) is an HIV-prevention strategy recommended for those at high-risk of infection, including adolescents and young people (AYP). We explored how PrEP roll-out could influence sexual risk behaviour among AYP in East and southern Africa. Twenty-four group discussions and 60 in-depth interviews were conducted with AYP between 13 and 24 years old, recruited from community settings in Uganda, Zimbabwe and South Africa, from September 2018 to January 2019. Participants perceived that PrEP availability could change sexual behaviour among AYP, influencing: (1) condom use (increased preference for condomless sex, reduced need and decrease in use of condoms, relief from condom use discomfort, consistent condom use to curb sexually transmitted infections and pregnancies); (2) sexual activities (increase in sexual partners and sexual encounters, early sexual debut, sexual experimentation and peace of mind during risky sex, sexual violence and perversion); (3) HIV risk perception (neglect of other HIV prevention strategies, unknown sexual partner HIV status, adoption of PrEP). PrEP initiation may be associated with increased interest in sexual activities and risky sexual behaviour among AYP. PrEP should be included as part of a combination package of HIV prevention strategies for AYP with methods to prevent other sexually transmitted infections and unwanted pregnancies.

RESUMEN

OBJECTIVES: Disruption to sexual health services during the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2; coronavirus disease 2019 [COVID-19]) pandemic may have adversely affected the provision of HIV post-exposure prophylaxis (PEP), possibly leading to increased HIV transmission. Globally, services have reported a reduction in the number of PEP prescriptions dispensed during lockdowns, although it is unclear why. Our primary objective was to describe the temporal change in weekly HIV PEP dispensed at six English sexual health clinics in 2020. METHODS: We performed a cross-sectional review of PEP prescriptions from six English centres during 2020. RESULTS: During 2020, 2884 PEP prescriptions were dispensed across the six centres studied, a fall of 34.5% from the 4403 PEP prescriptions in 2019. Before the COVID-related lockdown in 2020, the PEP dispensed was stable at 82.5 per week. Following the first lockdown, this fell to a nadir of 13 in week 14 (Figure 1). Prescriptions rose to a peak of 79 in week 37 and then declined to 32 prescriptions in the last week of 2020. There was no difference in the following characteristics of PEP recipients before and during the first lockdown: age, ethnicity, country of birth or the service the recipient attended. CONCLUSION: Whatever the reason for the fall in PEP seen in England over 2020, it is essential that HIV testing and access to HIV prevention is maintained for those in need.

RESUMEN

BACKGROUND: The global spread of SARS-CoV-2 has necessitated case isolation, with recommended isolation times based on mean time to viral clearance. CASE STUDY: We present a 28-year-old female living with vertically acquired HIV, undergoing chemotherapy for lymphoma who tested SARS-CoV-2-PCR positive for 164 days. The patient had a history of difficulty taking ARVs, with detectable HIV-RNA and CD4 count below 200 × 106 for the 8 years prior to presentation with symptoms. She stopped ARVs 10 months prior to experiencing fevers, night sweats and loose stool, with a viral load of 354,000 copies/ml and CD4 count of 30 × 106. Following no yield on basic investigations, positron emission tomography scan showed diffuse colonic and oesophageal avidity and a caecal biopsy showed diffuse large B-cell lymphoma. She re-started ARVs and underwent five cycles of R-CHOP chemotherapy. Her first positive SARS-CoV-2 PCR test was detected through routine asymptomatic screening. She self-isolated due to repeated positive tests on a further 8 swabs for a total of 164 days until a negative PCR test. She reported feeling low in mood and frustrated by repeated positive tests and the associated lack of social contact or ability to work. Her positive tests prevented in-person review by her HIV team, which impacted her ARV adherence leading to an unplanned break in therapy. CONCLUSIONS: Our case highlights the challenges to physical and mental health faced by patients with prolonged SARS-CoV-2 shedding and the need to develop surrogate markers for infectivity to enable prompt medical and psychological support and accurate advice about the need for isolation.

Brucella ceti infection is associated with a variety of disease outcomes in cetaceans globally. Multiple genotypes of B. ceti have been identified. This retrospective aimed to determine if specific lesions were associated with different B. ceti DNA sequence types (STs). Characterization of ST was performed on 163 samples from 88 free-ranging cetaceans, including common bottlenose dolphin Tursiops truncatus (T.t.; n = 73), common short-beaked dolphin Delphinus delphis (D.d.; n = 7), striped dolphin Stenella coeruleoalba (n = 3), Pacific white-sided dolphin Lagenorhynchus obliquidens (n = 2), sperm whale Physeter macrocephalus (n = 2), and harbour porpoise Phocoena phocoena (n = 1), that stranded along the coast of the US mainland and Hawaii. ST was determined using a previously described insertion sequence 711 quantitative PCR. Concordance with 9-locus multi-locus sequence typing was assessed in a subset of samples (n = 18). ST 26 was most commonly identified in adult dolphins along the US east coast with non-suppurative meningoencephalitis (p = 0.009). Animals infected with ST 27 were predominately perinates that were aborted or died shortly after birth with evidence of in utero pneumonia (p = 0.035). Reproductive tract inflammation and meningoencephalitis were also observed in adult T.t. and D.d. with ST 27, though low sample size limited interpretation. ST 23 infections can cause disease in cetacean families other than porpoises (Phocoenidae), including neurobrucellosis in D.d. In total, 11 animals were potentially infected with multiple STs. These data indicate differences in pathogenesis among B. ceti STs in free-ranging cetaceans, and infection with multiple STs is possible.

RESUMEN

BACKGROUND: Critical illness is often followed by mental and physical impairments. We aimed to assess the health-related quality of life (HRQoL), symptoms of anxiety and depression, and physical function in critically ill patients after discharge from the intensive care unit. METHODS: For this prospective cohort study we included all available adult patients admitted to the ICU for >24 h during a 12-month period. Home visits took place at 3 and 12 months after discharge from the hospital and included Short-Form Health Survey (SF-36), Hospital Anxiety and Depression Scale, and Chelsea Critical Care Assessment Too (CPAx). RESULTS: We visited 79 patients at 3 and 53 at 12 months. In patients with data from both visits the mental components SF-36 scores (median (IQR)) were 55 (43-63) at 3, and 58.5 (49.5-64) at 12 months; physical component SF-36 scores were 35 (28-45) at 3, and 36 (28-42) at 12 months. SF-36 subdomains of mental health, social functioning, and role emotional were close to normal. Vitality, bodily pain, general health, physical functioning, and role physical were severely affected. Incidences of anxiety and depression symptoms were 16%/8% at 3 and 13%/8% at 12 months) and physical function (CPAx) was 47 at both time points). CONCLUSION: We found no change in HRQoL, anxiety, and depression, or physical function from 3 months to 1 year. Physical health-related quality of life was impaired at both time points. Subdomain scores for physical health-related quality of life were affected more than mental domains at both time points.
