Evaluation of a workplace educational intervention on menopause: A quasi-experimental study.

OBJECTIVE: To evaluate the effects of a workplace educational intervention on menopause on self-efficacy regarding working during the climacteric. METHODS: Quasi-experimental design, with one intervention and one control group. Women aged 40 to 67, working in one of the two participating departments of a large municipality in the Netherlands, were recruited to participate in the study. The allocation of participants to intervention or control group was done at the departmental level. The main component of the multifaceted intervention consisted of educational workshops on menopause and work. The primary outcome was score on the Self-Efficacy to Manage Symptoms Scale. Secondary outcomes were scores on other self-efficacy scales, knowledge about the menopausal transition, menopausal symptoms, beliefs and behaviours and work-related variables. Differences between groups were analysed with Pearson's chi-square, Student's t-test or Mann-Whitney U. Analysis of covariance (ANCOVA) was used to correct for baseline and potential confounders. RESULTS: Data from 54 women were analysed, 25 in the intervention group and 29 in the control group. After 12 weeks of follow-up, the mean score on the Self-Efficacy to Manage Symptoms Scale was higher in the intervention group than in the control group: 6.52 (SD 1.45) versus 5.84 (SD 1.51), respectively, adjusted mean difference 0.75 (95 % CI 0.03-1.46, p = 0.040). The educational intervention increased self-reported knowledge (scored on the range 1-10) (adjusted mean difference 0.7, 95 % CI 0.26-1.15, p = 0.002) and resulted in a lower level of presenteeism (i.e., less impaired work performance) due to menopausal symptoms, measured by the Dutch Stanford Presenteeism Scale (adjusted mean difference 2.15, 95 % CI 0.13-4.18, p = 0.038), compared to the control group. CONCLUSIONS: This educational workplace intervention study shows promising positive effects on self-efficacy regarding working during the climacteric, knowledge about the menopausal transition and presenteeism due to menopausal symptoms. This is especially true for women already experiencing menopausal symptoms, while premenopausal women were harder to engage in the intervention. A larger study, with longer follow-up, preferably a randomized controlled trial, is needed to investigate the clinical relevance of these findings.

Attitude, confidence and social norm of Dutch occupational physicians regarding menopause in a work context.

OBJECTIVE: To explore the attitudes, confidence and social norm of Dutch occupational physicians (OPs) regarding menopause in a work context. STUDY DESIGN: A nationwide cross-sectional exploratory design. An invitation to participate in an online survey was sent to all OPs registered at the Dutch occupational physicians' society (n = 1663). This survey collected data about attitudes, confidence, social norm and current practice of OPs regarding menopause and work. Descriptive statistics and post hoc logistic multivariate analyses were used to evaluate the data. MAIN OUTCOME MEASURES: Attitudes, confidence and social norms in relation to menopause and work. RESULTS: Data from 267 OPs were analysed. Most OPs do recognize a role for menopause in presenteeism and sickness absence. However, 48% stated that women with bothersome menopausal symptoms are 'not sick' and 'just experiencing symptoms of a normal physiological process'. Over 56% of OPs find it difficult to assess the relationship between menopausal symptoms and work ability, and 63% to report menopause as a diagnosis in the context of a sick leave certification. Over 56% of OPs acknowledge that talking about menopause in the workplace is a taboo. A positive attitude towards menopause (OR 1.11, 95% CI 1.02-1.20) and greater confidence (OR 1.22, 95% CI 1.14-1.31) were associated with significantly higher levels of diagnosing menopause in sick leave certification. CONCLUSIONS: Dutch OPs generally have a positive attitude towards menopause, but perceive a lack of knowledge and a taboo culture around menopause in a work context. They indicate a need for education and a guideline on menopause and work.

Antigen-based diagnosis of Schistosoma infection in travellers: a prospective study.

BACKGROUND: Travellers infected with Schistosoma spp. might be pauci- or even asymptomatic on first presentation. Therefore, schistosomiasis may remain undiagnosed in this population. Active infection, as evidenced by the presence of the tissue-dwelling worm, can be demonstrated via the detection of adult worm-derived circulating anodic antigen (CAA) utilising a robust well-described lateral flow-(LF) based test applying background-free up-converting reporter particles (UCP). In this prospective study, we assessed the diagnostic value of serum and urine UCP-LF CAA test in comparison with two Schistosoma-specific serological assays detecting antibodies against adult worm antigen-immuno fluorescence assay (AWA-IFA) and against soluble egg antigen-enzyme-linked immunosorbent assay (SEA-ELISA) antigens in travellers. METHODS: Samples were collected from 106 Dutch travellers who reported freshwater contact in sub-Saharan Africa and who were recruited up to 2 years after return. Subjects were asked to complete a detailed questionnaire on travel history, water contact, signs and symptoms compatible with schistosomiasis. RESULTS: Two travellers were positive by serum CAA and an additional one by urine CAA. A total of 22/106 (21%) samples were antibody positive by AWA-IFA and 9/106 (9%) by SEA-ELISA. At follow-up 6 weeks and 6 months after praziquantel treatment, all seropositives remained antibody positive whereas CAA was cleared. Seropositivity could not be predicted by the type of fresh water-related activity, country visited or symptoms reported. CONCLUSION: The low number of UCP-LF CAA positives suggests that in travellers, active infections often do not establish or have very low worm burden. Based on our high seroconversion rates, we conclude that the AWA-IFA assay is the most sensitive test to detect schistosome exposure. Given the lack of predictive symptoms or risk factors, we recommend schistosomiasis screening at least by serology in all travellers with reported freshwater contact in high-endemic areas.

Immunogenicity of the Currently Recommended Pneumococcal Vaccination Schedule in Patients With Inflammatory Bowel Disease.

BACKGROUND: Patients with inflammatory bowel disease (IBD) are at increased risk of invasive pneumococcal infections. Therefore, vaccination with the 13-valent pneumococcal conjugate vaccine (PCV13) followed by 23-valent pneumococcal polysaccharide vaccine (PPSV23) 2 months later is recommended. However, the level of immunogenicity induced by this vaccination schedule in IBD patients with and without immunosuppressive medication remains unclear. METHODS: We prospectively assessed the immunogenicity of PCV13 followed by PPSV23 in IBD patients by measuring serotype-specific pneumococcal immunoglobulin G antibody concentrations at baseline and 4-8 weeks postvaccination. Response to vaccination was defined as a postvaccination antibody concentration ≥1.3 µg/mL for 70% of the measured serotypes. We analyzed the immunogenic effect of 4 different medication regimens: (1) conventional immunomodulators (ie, oral prednisolone >10 mg/day, thiopurines, methotrexate); (2) anti-tumor necrosis factor agents; (3) combination therapy; and (4) no treatment with immunosuppressive agents (control group). RESULTS: One hundred forty-one IBD patients were included, of whom 37 were controls. Adequate response to vaccination was 59% (61/104) in patients using immunosuppressive agents (groups 1-3) vs 81% (30/37) in controls (odds ratio, 0.33 [95% confidence interval, .13-.82]). A combination of different immunosuppressive drugs most severely impaired the immune response to pneumococcal vaccination (response, 52% [15/29]). CONCLUSIONS: Although the sequential vaccination schedule of PCV13 followed by PPSV23 is safe, immunogenic, and thus beneficial in the majority of IBD patients, those receiving immunosuppressive agents, and especially those receiving combination therapy, have an impaired immune response compared to controls. Therefore, preferably, vaccinations should be administered before the initiation of immunosuppressive therapy. CLINICAL TRIALS REGISTRATION: Dutch trial register #6315.

Improvement of menopausal symptoms and the impact on work ability: A retrospective cohort pilot study.

OBJECTIVE: In this study we aimed to pilot test the hypothesis that in women who are severely bothered by their menopausal complaints, improvement of menopausal symptoms is associated with an improvement in self-perceived work ability. STUDY DESIGN: This retrospective cohort study assessed the work ability of first-time attendees (n = 31) of a menopause clinic at baseline (T0) and 3-9 months follow-up (T1). All patients received care as usual according to local protocol, no interventions were applied by the researchers. Self-reported questionnaire data assessing work ability (Work Ability Index; WAI) and menopausal symptoms (Greene Climacteric Scale; GCS) were used. MAIN OUTCOME MEASURES: Multiple linear regression was used in an exploratory analysis to examine the relationship between change in WAI score (ΔWAI) and change in menopausal symptoms (ΔGCS), after adjustment for potential confounders. Additional exploratory univariate linear regression analyses were performed to assess the associations of change in WAI score with change in the different GCS domains and with type of treatment. RESULTS: Twenty-seven out of 31 women reported improvement in work ability at follow-up (T1) (M = 30.73, SD = 6.42 respectively, M = 34.86, SD = 5.98). All women reported to be less bothered by their menopausal symptoms at T1 (M = 26.57, SD = 8.69 respectively, M = 14.73, SD = 6.36). Multivariate linear regression demonstrated a significant association between the WAI and GCS change scores after correction for confounders (beta ΔGCS = 0.283, p = 0.014). After additional adjustment for WAI at baseline, this association was no longer significant (beta ΔGCS = 0.172, p = 0.164). Change in GCS depression domain (ΔGCS depression) was significantly associated with ΔWAI, although after correction for WAI at baseline the effect of ΔGCS depression was no longer significant (beta = 0.855, p = 0.113). The WAI and GCS change scores were highly correlated, as a result their coefficients were not statistically significant separately. CONCLUSIONS: Treatment aimed at alleviating menopausal symptoms in symptomatic women could lead to improvement of menopausal symptoms along with improvement in work ability. Improvement of depressive symptoms seem particularly important for this outcome.

Long-term pneumococcal vaccine immunogenicity following allogeneic hematopoietic stem cell transplantation.

Infection with Streptococcus pneumoniae is a life-threatening, but vaccine preventable complication in patients with allogeneic hematopoietic stem cell transplantation (allo-HSCT). The international consensus on post allo-HSCT immunization schedules, starting 3-6 months after HSCT, focuses on short-term immunogenicity while long-term immunogenicity is not well characterized. The current Dutch immunization schedule, which starts at 12 months post allo-HSCT, was developed as a result of concerns on the coverage of long-term immunogenicity in international guidelines. We recently encountered two cases of allo-HSCT recipients who developed invasive pneumococcal disease (IPD) despite adequate revaccinations, which led us to question the immunogenicity of pneumococcal vaccinations in this patient group, and whether the currently existing vaccination schedules are appropriate. We included allo-HSCT recipients, vaccinated from one year after transplantation, and tested antibody responses to pneumococcal vaccination. We also performed a systematic review. Antibody concentrations were measured in 42 of 103 (41%) patients, with a response rate of 85% to PCV13 and 62% to PPSV23-unique serotypes. In six relevant studies, protection rates varied between 64 and 98%. Antibody responses in early and late vaccination schedules were similar, but adequate antibody responses were maintained better after late vaccination. Therefore, we propose a vaccination schedule that combines the advantages of early and late vaccination. This new schedule has been introduced since March 2018 in the two academic hospitals in Amsterdam, The Netherlands.

The effect of immunosuppressive agents on immunogenicity of pneumococcal vaccination: A systematic review and meta-analysis.

INTRODUCTION: Patients with a weakened immune system due to immunosuppressive treatment are at increased risk of infection with Streptococcus pneumoniae. Although pneumococcal vaccination is highly recommended for those patients, the effectiveness of pneumococcal vaccination in this population remains largely unknown. Therefore, the objective of this PROSPERO-registered systematic review and meta-analysis was to evaluate the effect of the most commonly prescribed immunosuppressive agents such as azathioprine, methotrexate, anti-Tumor Necrosis Factor α (TNFα), or rituximab, on the initial serologic response to pneumococcal vaccination in patients with auto-immune disease. METHODS: We included 22 articles comprising 2077 patients, of whom 1623 were treated with immunosuppressive agents, and 454 were controls. RESULTS AND DISCUSSION: The findings of our systematic review indicate that, in patients treated with immunosuppressive medication and compared to controls, the initial serologic response to pneumococcal conjugate vaccine (PCV) and pneumococcal polysaccharide vaccine (PPSV) are impaired. Moreover, this impaired response was more profound after PCV than after PPSV. We hypothesize that the immunosuppressive medication mainly compromises the cellular immunity, explaining the more severely reduced response rate to PCV (which induces a T-cell dependent immune response), compared to PPSV. Treatment with TNFα blocking agents was associated with a more favorable response, compared to patients treated with other immunosuppressive medication. Targeted research applying uniform correlates of protection is needed to bridge the knowledge gap in vaccination immunology in this patient group. PROSPERO registration: CRD42017058364.

Incidence of invasive pneumococcal disease in immunocompromised patients: A systematic review and meta-analysis.

BACKGROUND: Invasive pneumococcal disease (IPD) is associated with high morbidity and mortality, with immunocompromised patients (ICPs) at particular risk. Therefore, guidelines recommend pneumococcal vaccination for these patients. However, guidelines are scarcely underpinned with references to incidence studies of IPD in this population. This, potentially results in unawareness of the importance of vaccination and low vaccination rates. The objective of this systematic review and meta-analysis was to assess the incidence of IPD in ICPs. METHODS: We systematically searched PubMed and Embase to identify studies in English published before December 6th, 2017 that included terms related to 'incidence', 'rate', 'pneumococcal', 'pneumoniae', 'meningitis', 'septicemia', or 'bacteremia'. We focused on patients with HIV, transplantation and chronic inflammatory diseases. RESULTS: We included 45 studies in the systematic review reporting an incidence or rate of IPD, defined as isolation of Streptococcus pneumoniae from a normally sterile site. Random effects meta-analysis of 38 studies showed a pooled IPD incidence of 331/100,000 person years in patients with HIV in the late-antiretroviral treatment era in non-African countries, and 318/100,000 in African countries; 696 and 812/100,000 in patients who underwent an autologous or allogeneic stem cell transplantation, respectively; 465/100,000 in patients with a solid organ transplantation; and 65/100,000 in patients with chronic inflammatory diseases. In healthy control cohorts, the pooled incidence was 10/100,000. DISCUSSION: ICPs are at increased risk of contracting IPD, especially those with HIV, and those who underwent transplantation. Based on our findings, we recommend pneumococcal vaccination in immunocompromised patients. PROSPERO REGISTRATION: ID: CRD42016048438.

Travel-related health problems in the immunocompromised traveller: An exploratory study.

BACKGROUND: Immunocompromised travellers (ICTs) are at increased risk of travel-related health problems. Therefore, they are advised to attend specialised pre-travel clinics for advice on vaccination, malaria chemoprophylaxis and on-demand antibiotics. However, studies yield conflicting data regarding travel-related health problems encountered by ICTs; questioning the rationale for certain advices, and particularly the advice of on-demand antibiotics. OBJECTIVE: To evaluate self-reported travel-related health problems, antibiotic use, medical visits and risk behaviours in ICTs and controls. METHODS: We conducted a questionnaire-based observational study with pilot character. We recruited participants from a (medical) pre-travel clinic. Telephone interviews were conducted 2-4 weeks post-travelling, applying a structured questionnaire. RESULTS: We included 30 ICTs and 30 controls. More ICTs than controls reported travel-related health problems, antibiotic use and medical visits, although not statistically significant. Travellers' diarrhoea appeared to be more severe in ICTs. Furthermore one ICT was hospitalized post-travel due to pneumonia. Of ICTs, 2/30 (7%) used on demand antibiotics while not indicated (according to the protocol of the Dutch national coordinating centre for travel advice or prescribed by a physician). Reversely, 6/30 (20%) did not use on demand antibiotics while actually indicated according to this protocol. DISCUSSION: Our findings substantiate the recommendation of on demand antibiotics. However, ICTs did often not use on demand antibiotics correctly; they therefore need very careful instructions.

Pre-travel care for immunocompromised and chronically ill travellers: A retrospective study.

BACKGROUND: Immunocompromised and chronically ill travellers (ICCITs) are susceptible to travel related diseases. In ICCITs, pre-travel care regarding vaccinations and prophylactics is complex. We evaluated the protection level by preventive measures in ICCITs by analysing rates of vaccination protection, antibody titres, and the prescription of standby antibiotics. METHODS: We analysed, and reported according to STROBE guidelines, pre-travel care data for ICCITs visiting the medical pre-travel clinic at the Academic Medical Centre, The Netherlands from 2011 to 2016. RESULTS: We analysed 2104 visits of 1826 ICCITs. Mean age was 46.6 years and mean travel duration 34.5 days. ICCITs on immunosuppressive treatment (29.7%), HIV (17.2%) or diabetes mellitus (10.2%) comprised the largest groups. Most frequently visited countries were Suriname, Indonesia, and Ghana. Most vaccination rates were >90%. Of travellers in high need of hepatitis A and B protection, 56.6 and 75.7%, underwent titre assessments, respectively. Of ICCITs with a respective indication, 50.6% received a prescription for standby antibiotics. CONCLUSION: Vaccination rates in our study population were overall comparable to those of healthy travellers studied previously in our centre. However, regarding antibody titre assessments and prescription of standby antibiotics, this study demonstrates that uniform pre-travel guidelines for ICCITs are highly needed.

Long-term sequelae of chikungunya virus disease: A systematic review.

BACKGROUND: The acute phase of chikungunya is well documented; less so are its long-term effects. This systematic literature review provides an overview of the currently available data. METHODS: We performed an electronic search in PubMed/Medline and checked reference lists. We included studies in English on long-term sequelae of chikungunya in adults and on long-term sequelae of congenital infection from 2000 to 2016. Case reports, reviews and studies with a follow-up shorter than 6 weeks were excluded. RESULTS: In total, 37 studies were included; with follow-up periods ranging from 1.5 to 72 months. Most studies were questionnaire-based studies only, in which clinical diagnoses such as arthritis, alopecia and depression were mostly recorded without professional verification. Persisting arthralgia/arthritis (arthralgia/joint stiffness plus joint swelling) was the most frequent problem encountered. Further frequently mentioned sequelae were alopecia and depression. Quality of life was reduced in many for months to years after the acute phase of chikungunya. Female gender, older age, some co-morbidities and the severity of the acute phase were associated with persistent arthralgia. Congenital infection was associated with neurocognitive dysfunctioning in early childhood. CONCLUSION: Chikungunya leads to (self-perceived) long-term sequelae in a considerable proportion of patients, impacting significantly on quality of life. Long-term chikungunya sequelae must be taken into account when dealing with this disease because of its important effect on public and individual health. Prospective large-scale, long-term studies with objective assessment of signs and symptoms attributed to the disease are needed to optimally quantify and qualify these problems.

The impact of menopause on work ability in women with severe menopausal symptoms.

OBJECTIVE: To measure the impact of menopause on work ability in women with severe menopausal symptoms. STUDY DESIGN: This cross-sectional study compared the work ability of a sample of otherwise healthy employed Dutch women (n=205) with that of a sample of first-time attendees of a menopause clinic (n=60); both groups were aged 44-60 years. Self-reported questionnaire data assessing work ability (Work Ability Index; WAI) and menopausal symptoms (Greene Climacteric Scale; GCS) were used. MAIN OUTCOME MEASURES: Logistic regression analyses were used to examine whether women with severe menopausal symptoms were more likely to have low work ability (defined as a score <37.0 points on the WAI) than were women in the reference group, after adjustment for individual and lifestyle factors. RESULTS: Symptomatic women had significantly higher total GCS scores (mean 26.7 vs 14.2, t=10.8, P<0.001) and significantly lower WAI scores (median 32.0 vs 40.0, U=2380, P<0.001) than the reference group. They were 8.4 times more likely to report low work ability than their healthy counterparts: 76.7% versus 30.2% (OR 8.4, 95% CI 4.1-17.2). CONCLUSIONS: Over three-quarters of symptomatic menopausal women report serious problems in dealing with the physical and mental demands of their work (recorded here as low work ability); hence these women might be at risk of prolonged sickness absence from work.

The impact of menopausal symptoms on work ability.

OBJECTIVE: Menopause is an important life event that may have a negative influence on quality of life. Work ability, a concept widely used in occupational health, can predict both future impairment and duration of sickness absence. The aim of this study was to examine the impact of menopausal symptoms on work ability. METHODS: This was a cross-sectional study that used a sample of healthy working Dutch women aged 44 to 60 years. Work ability was measured using the Work Ability Index, and menopausal symptoms were measured using the Greene Climacteric Scale. Stepwise multiple linear regression models were used to examine the relationship between menopausal symptoms and work ability. RESULTS: A total of 208 women were included in this study. There was a significant negative correlation between total Greene Climacteric Scale score and Work Ability Index score. Total Greene Climacteric Scale score predicted 33.8% of the total variance in the Work Ability Index score. Only the psychological and somatic subscales of the Greene Climacteric Scale were significant predictors in multiple linear regression analysis. Together, they accounted for 36.5% of total variance in Work Ability Index score. CONCLUSIONS: Menopausal symptoms are negatively associated with work ability and may increase the risk of sickness absence.
