Impact of post-COVID-19 condition on health status and activities of daily living: the PRIME post-COVID study.

OBJECTIVE: To assess health and activities of daily living (ADL) in SARS-CoV-2-positive adults with and without post-COVID-19 condition (PCC) and compare this with negative tested individuals. Furthermore, different PCC case definitions were compared with SARS-CoV-2-negative individuals. METHODS: All adults tested PCR positive for SARS-CoV-2 at the Public Health Service South Limburg (Netherlands) between June 2020 and November 2021 (n=41 780) and matched PCR negative individuals (2:1, on age, sex, year-quarter test, municipality; n=19 875) were invited by email. Health (five-level EuroQol five-dimension (EQ5D) index and EuroQol visual analogue scale (EQVAS)) and ADL impairment were assessed. PCC classification was done using the WHO case definition and five other common definitions. RESULTS: In total, 8409 individuals (6381 SARS-CoV-2 positive; 53±15 years; 57% female; 9 (7-11) months since test) were included. 39.4% of positives had PCC by the WHO case definition (EQVAS: 71±20; EQ5D index: 0.800±0.191; ADL impairment: 30 (10-70)%) and perceived worse health and more ADL impairment than negatives, that is, difference of -8.50 points (95% CI -9.71 to -7.29; p<0.001) for EQVAS, which decreased by 1.49 points (95% CI 0.86 to 2.12; p<0.001) in individuals with PCC for each comorbidity present, and differences of -0.065 points (95% CI -0.074 to -0.056; p<0.001) for EQ5D index, and +16.72% (95% CI 15.01 to 18.43; p<0.001) for ADL impairment. Health and ADL impairment were similar in negatives and positives without PCC. Replacing the WHO case definition with other PCC definitions yielded comparable results. CONCLUSIONS: Individuals with PCC have substantially worse health and more ADL impairment than negative controls, irrespective of the case definition. Authorities should inform the public about the associated burden of PCC and enable adequate support.

Differences in STI/HIV Burden and Sexual Health Care-Seeking Behavior Among First- and Second-Generation Migrant and Western-Born Male Sex Workers Who Have Sex With Men in the Netherlands: A Retrospective Cohort Study.

BACKGROUND: Globally, migrant sex workers have a higher burden of sexually transmitted infections (STI)/human immunodeficiency virus (HIV). This large study aimed to assess demographics, STI/HIV burden, and sexual health care-seeking behavior of first-generation migrant and second-generation migrant male sex workers who have sex with men (MSW-MSM) versus Western-born MSW-MSM. METHODS: Coded STI clinic consultations (n = 6970) from 3116 individual MSW-MSM attending any Dutch STI clinic between 2016 and 2021 were included. First-generation migrant: born outside of northern/central/southern/western Europe/North America/Oceania. Second-generation migrant: ≥1parent born outside of northern/central/southern/western Europe/North America/Oceania. Multivariable logistic regression analysis assessed associations between MSW-MSM groups and STI in first consultation in the data. A Cox proportional hazard regression compared the incidence of a first repeat consultation between migration groups, stratified by STI in first consultation. All analyses were adjusted for age and urbanity of STI clinic region. RESULTS: First-generation migrant MSW-MSM (n = 1085) were mostly born in Latin America (50%), whereas second-generation migrant MSW-MSM (n = 368) mostly originated from North Africa (30.4%). The proportion of STI diagnoses differed (33.2%, 29.3%, 23.3%; P < 0.001) between the first-generation migrant, second-generation migrant, and Western-born MSW-MSM. First-generation migrant MSW-MSM versus Western-born had an adjusted odds ratio of 1.6 (95% confidence interval, 1.3-1.9) of STI diagnosis in the first consultation. First-generation migrant MSW-MSM versus Western-born had an adjusted hazard ratio of 1.5 (95% confidence interval, 1.3-1.8) of having a first repeat consultation at any time, when stratified for no STI in the first consultation. CONCLUSIONS: The STI/HIV burden is high among all 3 MSW-MSM groups. First-generation migrants have higher odds of STI, but retention in care seems similar. Results highlight the importance of low-threshold STI testing and care for (migrant) MSW-MSM.

What determines mpox vaccination uptake? Assessing the effect of intent-to-vaccinate versus other determinants among men who have sex with men.

BACKGROUND: In response to the mpox outbreak, vaccination was offered in the Netherlands to men who have sex with men (MSM) at increased risk for mpox. Successful vaccination campaigns are leveraged by high intent-to-vaccinate, yet intent might not always lead to uptake. Therefore, we assessed the impact of intent-to-vaccinate and other factors on vaccination uptake among participants of the Amsterdam Cohort Studies (ACS). METHOD: In July 2022, prior to the mpox vaccination campaign, we distributed an online survey regarding mpox intent-to-vaccinate, as well as e.g. beliefs, attitude, subjective norms, and perception of risk among ACS participants (all MSM). Vaccination uptake was self-reported during study visits after August 2022. The association between vaccination intent and uptake, and determinants of intent, was jointly assessed using a structural equation model (SEM) based on components of the Theory of Planned Behavior (TPB). In a second SEM, determinants of intent were allowed to have a direct effect on vaccination uptake. RESULTS: 492 MSM (median age = 46 years) were included in analyses. 380 (77%) had high intent-to-vaccinate and 238 (48%) received at least one vaccine dose. In the first model with a direct relation between intent and uptake only, TBP components predicted intent as expected, and high intent-to-vaccinate was significantly associated with getting vaccinated (ß = 1.1, 95%CI = 0.6-1.5). However, 175/380 (46%) participants with high intent-to-vaccinate did not get vaccinated. The second model had an improved model fit compared to the first model. The effect of intent on uptake was non-significant, and only perceiving to be at higher risk of infection significantly increased vaccination uptake later on (ß = 0.42, 95%CI = 0.26-0.59). Having a steady relationship decreased the probability of vaccination (ß = -0.59, 95%CI = -1.0- -0.18). CONCLUSIONS: While intent-to-vaccinate for mpox was high among MSM, high intent did not necessarily result in vaccine uptake. Mpox risk perception might have played a more pivotal role in getting vaccinated, which may be related to the evolution of vaccination eligibility criteria and accessibility to the vaccine.

Using a theoretical framework of Intervention Mapping to inform public health communication messages designed to increase vaccination uptake; the example of mpox in the Netherlands.

INTRODUCTION: During an infectious disease outbreak, primary preventive pre-exposure vaccination (PPV) could substantially increase the potential for its control, if uptake is sufficiently high. An important tool to increase PPV uptake, are communication strategies, with tailored messages targeted to modify determinants for PPV uptake. Here, we take the example of the 2022 mpox multicountry outbreak, as we inform the development of communication strategies by applying a theoretical framework for selecting effective communication strategies. METHODS: The theoretical framework Intervention Mapping (IM) was applied during the outbreak to inform communications [program]. Steps included: 1. Creating a logic model of the problem [not accepting PPV] by reviewing available literature, conducting an online survey among people at risk of mpox exposure, and consulting community-members, healthcare-and communication professionals; 2. Creating a matrix of change [from lower to higher PPV acceptance]; and 3. Selecting theory-based methods and practical applications for communication messages to achieve the intended behaviour change (getting vaccinated). RESULTS: The program objective was to promote PPV uptake in people at risk of mpox exposure. Important changeable determinants identified included perceived risk and severity of mpox, importance to protect against mpox [attitude], experienced effectiveness of vaccination and side-effects [response efficacy], and social norm. Theory-based communication methods for optimizing these determinants include provision of facts [increasing knowledge], personalized risk and scenario-based risk information [addressing risk perception/severity], elaboration, arguments [stimulating a positive attitude], gain framing [increasing perceived response efficacy], guided practice [increasing skills/self-efficacy in overcoming barriers] and social norm approach [demonstrating positive norm]. Other key important factors include that communication delivery is uniform (across channels), clear, accessible, and with stigma-free messaging, and that is well-timed and repeated. CONCLUSION: IM provided a valuable tool in selecting communication methods to promote mpox vaccination uptake. These methods can be used to (more quickly) produce and implement a communication program in the context of possible future, vaccine-preventable, infectious disease outbreaks.

Prevalence of Long-term Symptoms Varies When Using Different Post-COVID-19 Definitions in Positively and Negatively Tested Adults: The PRIME Post-COVID Study.

Background: Long-term symptoms after a severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection (ie, post-coronavirus disease 2019 [COVID-19] condition or long COVID) constitute a substantial public health problem. Yet, the prevalence remains currently unclear as different case definitions are used, and negatively tested controls are lacking. We aimed to estimate post-COVID-19 condition prevalence using 6 definitions. Methods: The Prevalence, Risk factors, and Impact Evaluation (PRIME) post-COVID-19 condition study is a population-based sample of COVID-19-tested adults. In 2021, 61 655 adults were invited to complete an online questionnaire, including 44 symptoms plus a severity score (0-10) per symptom. Prevalence was calculated in both positively and negatively tested adults, stratified by time since their COVID-19 test (3-5, 6-11, or ≥12 months ago). Results: In positive individuals (n = 7405, 75.6%), the prevalence of long-term symptoms was between 26.9% and 64.1% using the 6 definitions, while in negative individuals (n = 2392, 24.4%), the prevalence varied between 11.4% and 32.5%. The prevalence of long-term symptoms potentially attributable to COVID-19 ranged from 17.9% to 26.3%. Conclusions: There is a (substantial) variation in prevalence estimates when using different post-COVID-19 condition definitions, as is current practice; there is limited overlap between definitions, indicating that the essential post-COVID-19 condition criteria are still unclear. Including negatives is important to determine long-term symptoms attributable to COVID-19. Trial registration: ClinicalTrials.gov Identifier: NCT05128695.

Newly diagnosed HIV and use of HIV-PrEP among non-western born MSM attending STI clinics in the Netherlands: a large retrospective cohort study.

Introduction: The World Health Organization recommends HIV-PrEP for all people at risk for HIV infection, which includes men who have sex with men (MSM). Substantial part of new HIV diagnoses in the Netherlands are in non-western born MSM. This study evaluated new HIV diagnoses and reported PrEP use among non-western born MSM and compared it to western-born MSM. To inform public health efforts in the context of equitable PrEP access, we further assessed sociodemographic factors related to higher HIV risk and lower PrEP use among non-western born MSM. Methods: Surveillance data of consultations among MSM in all Dutch STI-clinics (2016-2021) were analyzed. STI-clinics provide PrEP via the national pilot-program since August 2019. In non-western born MSM (born in Eastern-Europe/Latin-America/Asia/Africa/Dutch-Antilles/Suriname), sociodemographic factors were evaluated for association with HIV (by multivariable generalized estimating equations) and reported PrEP use in the past 3 months (by multivariable logistic regression; restricted to an at-risk for HIV person-level data-subset from August 2019). Results: New HIV infections were diagnosed among 1.1% (493/44,394) of non-western born MSM-consultations (vs. 0.4% among western-born MSM, 742/210,450). Low education (aOR: 2.2, 95%CI: 1.7-2.7, vs. high education) and age under 25 years (aOR: 1.4, 95%CI: 1.1-1.8, vs. age above 35 years) were associated with new HIV diagnoses. PrEP use in the past 3 months was 40.7% in non-western born MSM (1,711/4,207; 34.9% among western-born MSM, 6,089/17,458). PrEP use was lower among non-western born MSM aged under 25 years (aOR: 0.3, 95%CI: 0.2-0.4), living in less urban areas (aOR: 0.7, 95%CI: 0.6-0.8), and having low education level (aOR: 0.6, 95%CI: 0.5-0.7). Conclusion: Our study confirmed that non-western born MSM are an important key population in HIV prevention. Access to HIV prevention, including HIV-PrEP, should be further optimized to all non-western born MSM at risk for HIV, and specifically to those who are younger, live in less urban areas, and have a low education level.

Sexual (Risk) Behavior and Risk-Reduction Strategies of Home-Based Male Sex Workers Who Have Sex with Men (MSW-MSM) in The Netherlands: A Qualitative Study.

An understanding of sexual (risk) behavior is necessary to successfully develop prevention and care strategies for the sexually transmitted infections (STI) high-risk group of male sex workers who have sex with men (MSW-MSM). However, limited scientific knowledge is available on sexual (risk) behavior of (home-based) MSW-MSM. This study aimed to gain an understanding of sexual (risk) behavior, factors influencing sexual (risk) behavior, and applied risk-reduction strategies of home-based MSW-MSM. For this qualitative study, semi-structured individual interviews were conducted with 20 home-based MSW-MSM in the Netherlands. The interviews' recordings were transcribed verbatim and thematically analyzed with Atlas.ti 8. Condom use was reported to be high during anal sex, but low during oral sex and mostly determined by STI risk perception, trust in clients, and sexual pleasure. Many experienced condom failure, while few knew what to do after condom failure and were aware of post-exposure prophylaxis (PEP). Many MSW-MSM had chemsex in the past 6 months in order to loosen up and enhance sexual pleasure. Some were not vaccinated against hepatitis B virus (HBV), mainly due to the lack of information and awareness of HBV vaccination and low risk perception of HBV. The results of this study can be used to tailor future STI/HIV risk-reduction strategies for home-based MSW-MSM and to increase awareness and uptake of available STI/HIV prevention strategies such as P(r)EP and HBV vaccination.

Social networks and health behaviors during the COVID-19 pandemic: a qualitative study among older adults in the Netherlands.

Aim: Social networks, all social relationships that people have, may influence people's health behavior and well-being, which was evaluated in this qualitative study in older adults. Furthermore, we evaluated people's needs for strengthening social networks. Subject and methods: For this qualitative study, semi-structured interviews were conducted between May and July 2021 among 24 adults aged 60 years and older. Results: Respondents provided information on social network structure (number and types of relations) and function (social support). They received informational support from friends, emotional support from their partner/spouse, and all types of support (including practical support) from family. Respondents stated that their health behavior was mainly influenced by a partner/spouse. Family and friends were mostly for socializing. To strengthen networks, in-person bilateral or small group interactions were preferred. Conclusion: Family and friends were important social supporters and positively influenced health behaviors. This study emphasizes the importance of social networks in health promotion.

Refining Timely Diagnosis of Early Syphilis by Using Treponema pallidum PCR or IgM Immunoblotting Next to Conventional Serology for Syphilis.

Treponema pallidum subsp. pallidum is a fastidious spirochete and the etiologic agent of syphilis, a sexually transmitted infection (STI). Syphilis diagnoses and disease staging are based on clinical findings and serologic testing. Moreover, according to most international guidelines, PCR analysis of swab samples from genital ulcers is included in the screening algorithm where possible. It has been suggested that PCR might be omitted from the screening algorithm due to low added value. As an alternative to PCR, IgM serology might be used. In this study, we wanted to establish the added value of PCR and IgM serology for diagnosing primary syphilis. Added value was defined as finding more cases of syphilis, preventing overtreatment, or limiting the extent of partner notification to more recent partners. We found that both PCR and IgM immunoblotting could aid the timely diagnosis of early syphilis in ~24% to 27% of patients. PCR has the greatest sensitivity and can be applied to cases with an ulcer with suspected reinfection or primary infection. In the absence of lesions, the IgM immunoblot could be used. However, the IgM immunoblot has better performance in cases with suspected primary infection than in reinfections. The target population, testing algorithm, time pressures, and costs should determine whether either test provides sufficient value to be implemented in clinical practice.

Differences in non-positive intention to accept the COVID-19 booster vaccine between three countries in the cross-border region Meuse-Rhine Euroregion: The Netherlands, Belgium, and Germany.

COVID-19 booster vaccination has shown to add to the protection against infection with SARS-CoV2 and subsequent severe disease. This longitudinal cross-border study aimed to identify factors associated with COVID-19 booster vaccine intentions in an initially vaccinated adult population living in the Meuse-Rhine Euroregion (EMR; including the Netherlands, Belgium, and Germany) and differences between countries. Data collection took place in autumn of 2021 and consisted of online questionnaires sent to a random sample of the population based on governmental registries. Data from 3,319 fully and partially vaccinated adults were used to examine determinants of non-positive intention for a booster vaccination (i.e., uncertain or do not want), using multivariable logistic regression analyses weighted by age group, sex, and country. Compared to German residents, Dutch residents (OR = 2.4) and Belgian residents (OR = 1.4) were more likely to be uncertain or not want to receive a booster vaccine in September-October 2021. Factors independently associated with non-positive intention were female sex (OR = 1.6), absence of comorbidities (OR = 1.3), time since last vaccination less than 3 months ago for those fully vaccinated (OR = 1.6), being partially vaccinated (OR = 3.6), a negative experience with communication of COVID-19 measures (OR = 2.2), and regarding measures as ineffective (OR = 1.1). Results indicate that booster vaccine intentions differ between countries in the cross border Meuse-Rhine Euroregion. Non-positive intention for the booster vaccine is prevalent in all three countries of the EMR, but to a different extent, as shown in this study. Cross-border collaboration and sharing information and knowledge about vaccination strategies could play a role in limiting the impact of COVID-19.

Facility- and ward-level factors associated with SARS-CoV-2 outbreaks among residents in long-term care facilities: A retrospective cohort study.

OBJECTIVES: Long-term care facilities (LTCFs) have been disproportionately impacted by COVID-19. Yet, the reasons why certain LTCFs are affected more by outbreaks are poorly understood. This study aimed to identify the facility- and ward-level factors associated with SARS-CoV-2 outbreaks among LTCF residents. METHODS: We conducted a retrospective cohort study of multiple Dutch LTCFs (N = 60; with 298 wards providing care for ∼5600 residents) from September 2020 to June 2021. A dataset was constructed linking SARS-CoV-2 cases among LTCF residents to facility- and ward-level factors. Multilevel logistic regression analyses examined the associations between these factors and the likelihood of a SARS-CoV-2 outbreak among residents. RESULTS: During periods of the Classic variant, the mechanical recirculation of air was associated with significantly increased odds of a SARS-CoV-2 outbreak. During periods of the Alpha variant, the factors associated with significantly increased odds included large ward size (≥21 beds), wards providing psychogeriatric care, fewer restrictions on staff movement between wards and facilities, and a greater number of cases among staff (>10 cases). CONCLUSION: Policy and protocols on reducing resident density, staff movement, and mechanical recirculation of air in buildings are recommended to enhance outbreak preparedness in LTCFs. The implementation of low-threshold preventive measures among psychogeriatric residents is important because they appear as a particularly vulnerable group.

A systematic review of barriers and facilitators for hepatitis B and C screening among migrants in the EU/EEA region.

Introduction: Hepatitis B and C are a threat to public health. Screening of high-risk groups, such as migrants from high-endemic areas, enables early identification and treatment initiation. This systematic review identified barriers and facilitators for hepatitis B and C screening among migrants in the European Union/European Economic Area (EU/EEA). Methods: Following PRISMA guidelines, databases PubMed, Embase via Ovid, and Cochrane were searched for English articles published between 1 July 2015 and 24 February 2022. Articles were included, not restricted to a specific study design, if they elaborated on HBV or HCV screening in migrant populations from countries outside Western Europe, North America, and Oceania, and residing in EU/EEA countries. Excluded were studies with solely an epidemiological or microbiological focus, including only general populations or non-migrant subgroups, or conducted outside the EU/EEA, without qualitative, quantitative, or mixed methods. Data appraisal, extraction, and quality assessment were conducted and assessed by two reviewers. Barriers and facilitators were categorized into seven levels based on multiple theoretical frameworks and included factors related to guidelines, the individual health professional, the migrant and community, interaction, the organization and economics, the political and legal level, and innovations. Results: The search strategy yielded 2,115 unique articles of which 68 were included. Major identified barriers and facilitators to the success of screening related to the migrant (knowledge and awareness) and community level (culture, religion, support) and the organizational and economic level (capacity, resources, coordinated structures). Given possible language barriers, language support and migrant sensitivity are indispensable for facilitating interaction. Rapid point-of-care-testing is a promising strategy to lower screening barriers. Discussion: The inclusion of multiple study designs provided extensive insight into barriers, strategies to lower these barriers, and facilitators to maximize the success of screening. A great variety of factors were revealed on multiple levels, therefore there is no one-size-fits-all approach for screening, and initiatives should be adopted for the targeted group(s), including tailoring to cultural and religious beliefs. We provide a checklist of facilitators and barriers to inform adapted interventions to allow for optimal screening impact.

Chlamydia trachomatis Coinfection Does Not Influence Mycoplasma genitalium Bacterial Load in Urogenital Samples.

BACKGROUND: Mycoplasma genitalium (MG) is associated with urethritis in men and weakly associated with pelvic inflammatory disease in women. Mycoplasma genitalium coinfections with Neisseria gonorrhoeae (NG) and Chlamydia trachomatis (CT) are commonly reported; however, little is known about their interaction. One study suggested that MG/NG coinfections might increase the bacterial load of NG, which has been shown to have a higher transmission potential. As even less is known about the impact of a simultaneous MG/CT infection, we assessed whether patients with urogenital MG/CT coinfections have a higher bacterial load than patients with a single infection. METHODS: There were 1673 urogenital samples from patients from a population-based chlamydia study, and our sexually transmitted infection clinic tested for both CT and MG. When positive, the load was quantified. Nonparametric tests compared the CT and MG load, and linear regression analyses tested the association of the CT and MG load within a patient. RESULTS: In 60 MG-positive patients, MG load ranged from 1.7 to 6.0 log10 copies/ml, similar to the CT load distribution. Only 6 patients were MG-positive and CT-negative, but the MG load distribution was similar to that of CT-positive patients (n.s.). The MG and CT load was unrelated in coinfected persons (n.s.). CONCLUSIONS: We found no correlation between the CT and MG load in urogenital samples, and the MG load distribution was similar in CT-positive and CT-negative patients. These results could have implications for the transmission risk of these infections.

Alcohol and drug use during sex and its association with sexually transmitted infections: a retrospective cohort study among young people aged under 25 years visiting Dutch STI clinics.

INTRODUCTION: Alcohol use and drug use are common behaviours among young people. STI positivity is higher in young people than in people aged above 25 years. While there is an increasing amount of knowledge about drug use during sex among men who have sex with men (MSM), data on this behaviour among young women and heterosexual men are scarce. Therefore, this study aims to assess the proportion and characteristics of women and heterosexual men aged under 25 years reporting alcohol and/or drug use during sex and its association with STI positivity. METHODS: Surveillance data of heterosexual individuals younger than 25 years visiting two Dutch STI clinics between 2016 and 2019 were assessed (n=11 714). We used multivariable logistic regression analyses to assess associations between alcohol and drug use during sex and STI positivity (Chlamydia trachomatis and/or Neisseria gonorrhoeae diagnosis), adjusting for sociodemographic characteristics (sex, age, ethnicity, educational level, socioeconomic status and urbanisation) and sexual behaviour (condom use, number of sex partners). RESULTS: Alcohol use during sex was reported by 45.3% (5311/11 714; 49.5% in men vs 43.2% in women, p<0.001) and drug use during sex by 22.0% (2580/11 714; 30.7% in men vs 17.6% in women, p<0.001). The most reported drugs were cannabis (17.9%), ecstasy (XTC)/methylenedioxymethamphetamine (MDMA) (6.9%) and cocaine (4.7%). The use of at least one of the following drugs (XTC/MDMA, cocaine, speed, ketamine, gamma-hydroxybutyrate (GHB)/gamma-butyrolactone (GBL), heroin, crystal meth and/or designer drugs) was significantly associated with STI positivity after adjustment for sociodemographic characteristics (adjusted OR (aOR): 1.3, 95% CI 1.1 to 1.4), but this association did not remain significant after adjustment for sexual behaviour (aOR: 1.12, 95% CI 0.94 to 1.34). Significant associations between drug use during sex and inconsistent condom (aOR: 2.5, 95% CI 1.9 to 3.2) use and having four or more sex partners (aOR: 3.2, 95% CI 2.8 to 3.6) in the past 6 months were assessed. DISCUSSION: Alcohol and drug use during sex was highly prevalent among young women and heterosexual men visiting the STI clinic and drug use during sex was associated with an increased risk for STI, probably mediated by sexual behaviour. This indicates that a holistic health promotion strategy, addressing STI prevention and alcohol and drug use-related harm reduction, is important in this group. STI clinics should address this behaviour not only among MSM, but also among young women and heterosexual men.

High proportions of post-exertional malaise and orthostatic intolerance in people living with post-COVID-19 condition: the PRIME post-COVID study.

Background: Exercise-based treatments can worsen/exacerbate symptoms in people who were SARS-CoV-2 positive and living with post-COVID-19 condition (PL-PCC) and who have post-exertional malaise (PEM) or orthostatic intolerance (OI). Nevertheless, PEM and OI are not routinely assessed by clinicians. We estimated PEM and OI proportions in PL-PCC, as well as in people not living with PCC (PnL-PCC) and negatives (i.e., never reported a SARS-CoV-2 positive test), and identified associated factors. Methods: Participants from the Prevalence, Risk factors, and Impact Evaluation (PRIME) post-COVID-19 condition study were included. PEM and OI were assessed using validated questionnaires. PCC was defined as feeling unrecovered after SARS-CoV-2 infection. Multivariable regression analyses to study PEM and OI were stratified for sex. Results: Data from 3,783 participants were analyzed. In PL-PCC, the proportion of PEM was 48.1% and 41.2%, and the proportion of OI was 29.3% and 27.9% in women and men, respectively. Proportions were higher in PL-PCC than negatives, for PEM in women OR=4.38 [95%CI:3.01-6.38]; in men OR = 4.78 [95%CI:3.13-7.29]; for OI in women 3.06 [95%CI:1.97-4.76]; in men 2.71 [95%CI:1.75-4.21]. Associated factors were age ≤ 60 years, ≥1 comorbidities, and living alone. Conclusion: High proportions of PEM and OI are observed in PL-PCC. Standard screening for PEM and OI is recommended in PL-PCC to promote appropriate therapies.

Culture-Independent Genotyping Improves Surveillance of Neisseria gonorrhoeae, Especially in Oropharyngeal Samples, the Netherlands, 2017 to 2018.

It is important i to monitor the transmission and antimicrobial resistance of Neisseria gonorrhoeae (NG). Current surveillance relies on culturing, which frequently fails. Previously, a culture-independent genotyping method was developed based on NG multi-antigen sequence typing (NG-MAST). To determine whether crucial sequence types (STs) are missed during culture-dependent surveillance, NG-positive NAAT samples were genotyped, and the results of the culture-positive and culture-negative samples were compared. In total, 196 NG-positive NAAT samples, from January 2017 until August 2018, which were also routinely cultured, were retrospectively included. Genotyping was successful in 152 NAAT samples (77.0%), 33 NAAT samples failed, and 11 NAAT samples showed possible mixed strain infections. Oropharyngeal samples (n = 16) showed the largest increase in typing rate from 6.3% (1/16) success in culture-dependent genotyping to 81.3% (13/16) in culture-independent genotyping. Nine genogroups (n ≥ 5 samples) were found; all included both culture-positive and culture-negative NG. However, culture-independent surveillance revealed 14 additional STs in the culture-negative samples. Overall, culture-dependent surveillance could detect all genogroups, indicating that major trends could be identified with culture-dependent surveillance. However, culture-independent surveillance provides more STs, mixed infections and more oropharyngeal samples, giving a more detailed view and could result in an earlier detection of outbreaks and transmission.

Evaluation of symptomatology and viral load among residents and healthcare staff in long-term care facilities: A coronavirus disease 2019 retrospective case-cohort study.

OBJECTIVES: We evaluated COVID-19 symptoms, case fatality rate (CFR), and viral load among all Long-Term Care Facility (LTCF) residents and staff in South Limburg, the Netherlands (February 2020-June 2020, wildtype SARS-CoV-2 Wuhan strain). METHODS: Patient information was gathered via regular channels used to notify the public health services. Ct-values were obtained from the Maastricht University Medical Centre laboratory. Logistic regression analyses were performed to assess associations between COVID-19, symptoms, CFR, and viral load. RESULTS: Of 1,457 staff and 1,540 residents, 35.1% and 45.2% tested positive for COVID-19. Symptoms associated with COVID-19 for female staff were fever, cough, muscle ache and loss of taste and smell. Associated symptoms for men were cough, and loss of taste and smell. Associated symptoms for residents were subfebrility, fatigue, and fever for male residents only. LTCF residents had a higher mean viral load compared to staff. Male residents had a higher CFR (35.8%) compared to women (22.5%). Female residents with Ct-values 31 or less had increased odds of mortality. CONCLUSIONS: Subfebrility and fatigue seem to be associated with COVID-19 in LTCF residents. Therefore, physicians should also consider testing residents who (only) show aspecific symptoms whenever available resources prohibit testing of all residents. Viral load was higher in residents compared to staff, and higher in male residents compared to female residents. All COVID-19 positive male residents, as well as female residents with a medium to high viral load (Ct-values 31 or lower) should be monitored closely, as these groups have an overall increased risk of mortality.

Intention to use and acceptability of home-based sexual health care among men who have sex with men who previously attended clinic-based sexual health care.

The COVID-19 pandemic has temporarily disrupted access to clinic-based sexual health care for men who have sex with men (MSM) in the Netherlands. The importance of home-based sexual health care has been underpinned as an extension of clinic-based care. This paper aims to assess intention to use, and acceptability of home-based sexual health care among MSM who previously attended clinic-based sexual health care. In November 2020, 424 MSM who had attended an STI clinic pre-pandemic were invited to participate in an online survey; 154 MSM completed the survey (response 36%). Intention to use self-sampling STI/HIV tests was assessed (median; scale 0-100) and compared across sociodemographic and sexual behavior characteristics by Kruskal-Wallis H tests. Descriptive analyses provided insights in acceptability of home-based sexual health care. Of participants (median age 47), 60.4% (93/154) tested for STI/HIV in the past 6 months, most of them attended a clinic. The median score on intention to use self-sampling tests was 86.5 (SD = 33.4) and did not differ by sociodemographic or sexual behavioral characteristics (all p-values > 0.1). Participants were positive toward online sexual health counseling (median attitude = 75.0, SD = 29.6) and their main preferred topics were PrEP use and STI/HIV testing. MSM who attended clinic-based care expressed intention to use self-sampling tests and a positive attitude toward online sexual health counseling. Home-based sexual health care elements are not currently integrated within Dutch clinic-based sexual health care and should be considered an addition for continued provision of care and extended reach of MSM.
