Attitudes toward genetic testing, family planning and preimplantation genetic testing in families with a germline CDKN2A pathogenic variant.

Individuals with a germline CDKN2A pathogenic variant (PV) have a highly increased life time risk of melanoma and pancreatic cancer. This cross-sectional study assessed the attitudes among toward genetic testing, family planning, and preimplantation genetic testing (PGT) in confirmed CDKN2A PV carriers and individuals with a 50% risk of the PV (at-risk carriers) using of a one-time questionnaire.A total of 537 individuals were screened for eligibility, of whom 208 of 366 (57%) confirmed carriers (56% female, median age 54 years [IQR 46-63]) and 39 of 171 (23%) at-risk carriers (59% female, median age of 26 years [IQR 22-32]) participated in the study. Primary motivations for genetic testing were to gain control over their personal and children's cancer risk, as well as increasing cancer surveillance practices. In contrast, concerns about obtaining a mortgage and life insurance were frequently cited as reasons for postponing genetic testing. Family planning decisions remained largely unaffected in both confirmed and at-risk carriers; however, the majority of confirmed carriers were still unaware of their familial or personal cancer risk when starting a family. More than 60% of the participants were unfamiliar with PGT and only a minority (19% of confirmed carriers and 10% of at-risk carriers) would be open to considering PGT as a reproductive option. This study found different attitudes toward genetic testing, family planning, and PGT among individuals affected by the CDKN2A PV. Understanding these different attitudes can help clinicians to address the complexities surrounding these issues, especially for younger individuals facing difficult decisions about the timing of genetic testing, family planning, and the potential use of assisted reproductive options.

Sociodemographic inequality in children aged 0-19 years with and without parents diagnosed with heart disease: a Danish nationwide register-based study.

OBJECTIVES: This study aimed to estimate the prevalence of children aged 0-19 years who have a parent with a history of heart disease and investigate their sociodemographic characteristics. STUDY DESIGN: A national register-based study. METHODS: From the Danish Fertility Register and the Danish National Patient Register information on children of parents with ischemic heart disease, arrhythmia, heart failure and heart valve disease in the period 1981-2018 were obtained. Statistical analyses including descriptive statistics, logistic and linear regression were used to illuminate associations between parental heart disease and sociodemographic characteristics. RESULTS: The study population consisted of 142,480 children aged 0-19 years with at least one parent diagnosed with heart disease, corresponding to every 9th child in Denmark in 2018. The number increased from 4.5% in 2002 to 11.1% in 2018. In the study population most had a father with heart disease (57.8%) and 4.6% had two parents with heart disease. Parents with heart disease had significantly higher odds of being out of work (OR 1.68, 95% CI 1.64; 1.72), in a single-parent household (OR 1.09, 95% CI 1.07; 1.11), divorced or widowed (OR: 1.10, 95% CI 1.08; 1.12), having a lower educational level (OR 1.35, 95% CI 1.33; 1.37), and a lower family income (-42,410 DKR, 95% CI -50,306; -34,514, P < 0.0001) compared to those without heart disease. CONCLUSION: Children affected by parental heart disease comprise a substantial part of the Danish population. These have significantly different sociodemographic characteristics than children in families without parental heart disease, which might affect social heritage and parental capacity.

The Double Antibody Drug Conjugate (DAD) phase I trial: sacituzumab govitecan plus enfortumab vedotin for metastatic urothelial carcinoma.

BACKGROUND: The antibody-drug conjugates sacituzumab govitecan (SG) and enfortumab vedotin (EV) are standard monotherapies for metastatic urothelial carcinoma (mUC). Given the different targets and payloads, we evaluated the safety and efficacy of SG + EV in a phase I trial in mUC (NCT04724018). PATIENTS AND METHODS: Patients with mUC and Eastern Cooperative Oncology Group performance status ≤1 who had progressed on platinum and/or immunotherapy were enrolled. SG + EV were administered on days 1 + 8 of a 21-day cycle until progression or unacceptable toxicity. Primary endpoint was the incidence of dose-limiting toxicities during cycle 1. The number of patients treated at each of four pre-specified dose levels (DLs) and the maximum tolerated doses in combination (MTD) were determined using a Bayesian Optimal Interval design. Objective response, progression-free survival, and overall survival were secondary endpoints. RESULTS: Between May 2021 and April 2023, 24 patients were enrolled; 1 patient never started therapy and was excluded from the analysis. Median age was 70 years (range 41-88 years); 11 patients received ≥3 lines of therapy. Seventy-eight percent (18/23) of patients experienced grade ≥3 adverse event (AE) regardless of attribution at any DL, with one grade 5 AE (pneumonitis possibly related to EV). The recommended phase II doses are SG 8 mg/kg with EV 1.25 mg/kg with granulocyte colony-stimulating factor support; MTDs are SG 10 mg/kg with EV 1.25 mg/kg. The objective response rate was 70% (16/23, 95% confidence interval 47% to 87%) with three complete responses; three patients had progressive disease as best response. With a median follow-up of 14 months, 9/23 patients have ongoing response including 6 responses lasting over 12 months. CONCLUSIONS: The combination of SG + EV was assessed at different DLs and a safe dose for phase II was identified. The combination had encouraging activity in patients with mUC with high response rates, including clinically significant complete responses. Additional study of this combination is warranted.

Prevalence and risk factors of Brachyspira spp. in pig herds with a history of diarrhoea in six European countries.

Swine dysentery and porcine intestinal spirochaetosis caused by Brachyspira (B.) hyodysenteriae and B. pilosicoli, respectively, are important diseases in swine production worldwide. The aim of this study was to assess the prevalence of both pathogens in farms with a history of diarrhoea within the last 12 months in Denmark, France, Germany, the Netherlands, Spain, and United Kingdom. In addition, risk factors for their prevalence and correlations between presence of different Brachyspira spp. and Lawsonia intracellularis were investigated. Therefore, faecal samples of 6355 nursery to finishing pigs out of 144 herds were sampled in 2017/2018 during a prevalence study on Lawsonia intracellularis, followed by polymerase chain reaction analysis for Brachyspira spp. detection. Herd prevalence differed significantly between countries, from 4.2% to 45.8% for B. hyodysenteriae and 8.3-87.5% for B. pilosicoli, respectively (p < 0.01). For the within-herd prevalence (in positive herds), these values ranged from 2.2% to 27.0% for B. hyodysenteriae and 3.3-50.8% for B. pilosicoli. Mixed infections occurred in 34.1% and 58.7% of B. hyodysenteriae positive samples with Lawsonia intracellularis or B. pilosicoli, respectively. In 43.2% of B. pilosicoli positive samples, Lawsonia intracellularis was detected simultaneously. Overall, nursery pigs were significantly less often positive for one of the pathogens than growing or finishing pigs (p < 0.001). The absence of gastrointestinal problems like diarrhoea, routine use of antimicrobials and well performed biosecurity measures were some of the factors associated with lower detection rate of Brachyspira spp. Surprisingly, deworming of different age categories also showed associations with the detection of Brachyspira spp. which, however, were not always equally directed, and therefore require further investigations. The only risk factor significant for both Brachyspira spp. was the median number of ≥ 30 nursery pigs per pen after weaning, compared to smaller group sizes. Both pathogens were detected with varying frequency between the six European countries. This should be considered in the probability of disease and in case of transnational transport, to prevent spread of pathogens. In addition, the frequent presence of mixed infections in some countries should be taken into account in diagnostics. The most important protective factors against Brachyspira spp. presence on farm are biosecurity measures, while potential new factors such as deworming still require further investigation.

Reference ranges of anti-Müllerian hormone and interaction with placental biomarkers in early pregnancy: the Generation R Study, a population-based prospective cohort study.

Objective: The primary objective of this study is to establish maternal reference values of anti-Müllerian hormone (AMH) in a fertile multi-ethnic urban pregnant population and to evaluate the effect of gestational age. The secondary objective of this study is to explore the association between AMH and placental biomarkers. Design: This study was embedded in the Generation R Study, an ongoing population-based prospective cohort study from early pregnancy onwards. Setting: City of Rotterdam, the Netherlands, out of hospital setting. Patients: In 5806 women, serum AMH levels were determined in early pregnancy (median 13.5 weeks; 95% range 10.5-17.2). Intervention(s): None. Main outcome measures: Maternal AMH levels in early pregnancy and its association with placental biomarkers, including human chorionic gonadotrophin (hCG), soluble fms-like tyrosine kinase-1 (sFLT), and placental growth factor (PLGF). Results: A nomogram of AMH in early pregnancy was developed. Serum AMH levels showed a decline with advancing gestational age. Higher AMH levels were associated with a higher level of the placental biomarkers hCG and sFLT in early pregnancy. This last association was predominantly mediated by hCG. AMH levels were negatively associated with PLGF levels. Conclusion: In this large study, we show that AMH levels in early pregnancy decrease with advancing gestational age. The association between AMH and the placental biomarkers hCG, sFLT, and PLGF suggests a better placental development with lower vascular resistance in mothers with higher AMH levels. Hence, AMH might be useful in predicting adverse pregnancy outcomes due to impaired placental development.

Compliance with a novel hand hygiene protocol tailored to non-sterile healthcare workers in the operating theatre.

BACKGROUND: Observing hand hygiene compliance (HHC) among non-sterile healthcare workers (HCWs) in the operating theatre (OT) is challenging as there are no tailored protocols or observation tools. AIM: To develop and test a hand hygiene protocol tailored to non-sterile HCWs in the OT. METHODS: In this prospective observational study, nine hospitals in the Rotterdam-Rijnmond region provided input on a draft protocol on hand hygiene in the OT, resulting in a new consensus protocol for the region. An observation tool based on the protocol was developed and tested. HHC rates with 95% confidence intervals (CI) were calculated by type of hospital and type of HCW. FINDINGS: The protocol has three sections: (1) written general hand hygiene rules; (2) written hand hygiene rules specific for anaesthesia and surgery; and (3) visual representation of the OT, divided into four hand hygiene areas. Hand hygiene should be applied when changing area. Average HHC of 48.0% (95% CI 45.2-61.2%) was observed in OTs across all hospitals. HHC was highest in the two specialized hospitals (64.0%, 95% CI 30.6-89.8%; 76.7%, 95% CI 62.8-84.5%) and lowest in the academic teaching hospital (23.1%, 95% CI 0.0-45.8%). In terms of type of HCW, HHC was lowest among anaesthesiologists (31.6%, 95% CI 19.2-62.4%) and highest among OT assistants (57.4%, 95% CI 50.1-78.2%). CONCLUSION: This uniform way of observing HHC in the OT enables evaluation of the effectiveness of interventions in the OT and facilitates friendly competition. In the Rotterdam-Rijnmond region, HHC in the OT was below 50%; this needs to be addressed, particularly in teaching hospitals and among physicians.

Severe multisystem inflammatory syndrome (MIS-C/A) after confirmed SARS-CoV-2 infection: a report of four adult cases.

BACKGROUND: Multisystem inflammatory syndrome (MIS) triggered by a recent SARS-Cov-2 infection has been recognised worldwide. Although predominantly affecting children (MIS-C), similar presentations have been reported among adults (MIS-A). METHOD: A retrospective case series describing four critically ill patients with MIS-C/A diagnosed between January and April 2021 at Sahlgrenska University Hospital, Gothenburg, Sweden. Clinical presentation, laboratory and radiological findings, treatment and outcome are reported. RESULTS: Cases occurred in previously healthy patients with a history of laboratory-confirmed mild SARS-CoV-2 infection four to seven weeks earlier. The median age was 24 years (range 19-43) and 3/4 were male. All fulfilled suggested MIS-C/A criteria according to the US Centre for Disease Control and all required care at an intensive care unit. Treatment was initiated with intravenous immunoglobulin, interleukin-1-receptor antagonists, and pulse steroids in 3/4 cases which resulted in rapid clinical improvement. No severe complications were noticed in any case during a three-month follow-up period. CONCLUSION: MIS-C/A should be considered, irrespective of age, in patients with fever, hyperinflammation and multiple organ system involvements emerging weeks after COVID-19. Previously suggested treatment regimens for MIS-C seem to be applicable also for MIS-A.

COVID-19 vaccination and breakthrough infections in patients with cancer.

BACKGROUND: Vaccination is an important preventive health measure to protect against symptomatic and severe COVID-19. Impaired immunity secondary to an underlying malignancy or recent receipt of antineoplastic systemic therapies can result in less robust antibody titers following vaccination and possible risk of breakthrough infection. As clinical trials evaluating COVID-19 vaccines largely excluded patients with a history of cancer and those on active immunosuppression (including chemotherapy), limited evidence is available to inform the clinical efficacy of COVID-19 vaccination across the spectrum of patients with cancer. PATIENTS AND METHODS: We describe the clinical features of patients with cancer who developed symptomatic COVID-19 following vaccination and compare weighted outcomes with those of contemporary unvaccinated patients, after adjustment for confounders, using data from the multi-institutional COVID-19 and Cancer Consortium (CCC19). RESULTS: Patients with cancer who develop COVID-19 following vaccination have substantial comorbidities and can present with severe and even lethal infection. Patients harboring hematologic malignancies are over-represented among vaccinated patients with cancer who develop symptomatic COVID-19. CONCLUSIONS: Vaccination against COVID-19 remains an essential strategy in protecting vulnerable populations, including patients with cancer. Patients with cancer who develop breakthrough infection despite full vaccination, however, remain at risk of severe outcomes. A multilayered public health mitigation approach that includes vaccination of close contacts, boosters, social distancing, and mask-wearing should be continued for the foreseeable future.

Microbiological colonization of peripheral venous catheters: a prospective observational study in a Swedish county hospital.

BACKGROUND: Most peripheral venous catheters (PVCs) used in Scandinavia are fitted with an injection port, creating an open PVC system. This port is difficult to disinfect, which may lead to the introduction of micro-organisms upon use. AIM: To investigate the prevalence of microbiological colonization of the injection port and internal lumen of ported PVCs with a minimum dwell time of 48 h at sample collection. METHODS: Adult patients admitted to different medical and surgical departments and the intensive care unit were invited to participate in this prospective observational study. With the PVC in situ, the injection port and internal lumen were swabbed and cultured separately. Demographic and clinical data were collected to compare patients with colonized and non-colonized PVCs. FINDINGS: In total, 300 PVCs from 300 patients were analysed. Of these, 33 patients (11.0%) had at least one positive culture. The colonization locations were as follows: port only, 26 (8.7%); internal lumen only, 5 (1.7%); and port and internal lumen, 2 (0.7%). The colonization rate was significantly higher in the injection port than in the internal lumen (P<0.0001). A ported PVC inserted in the hand incurred a significant risk of colonization (P=0.03). The odds ratio for colonization among patients in the infectious diseases department was 0.1 (95% confidence interval 0.1-1; P<0.06) compared with patients in the medical department. CONCLUSION: This study showed that 11% of ported PVCs were colonized by micro-organisms, with the vast majority (8.7%) of colonization occurring in the injection port. CLINICAL TRIAL REGISTRATION: ClinicalTrials.gov; ID NCT03351725.

Acceptability, feasibility, and likelihood of stakeholders implementing the novel BPaL regimen to treat extensively drug-resistant tuberculosis patients.

BACKGROUND: BPaL, a 6 month oral regimen composed of bedaquiline, pretomanid, and linezolid for treating extensively drug-resistant tuberculosis (XDR-TB) is a potential alternative for at least 20 months of individualized treatment regimens (ITR). The ITR has low tolerability, treatment adherence, and success rates, and hence to limit patient burden, loss to follow-up and the emergence of resistance it is essential to implement new DR-TB regimens. The objective of this study was to assess the acceptability, feasibility, and likelihood of implementing BPaL in Indonesia, Kyrgyzstan, and Nigeria. METHODS: We conducted a concurrent mixed-methods study among a cross-section of health care workers, programmatic and laboratory stakeholders between May 2018 and May 2019. We conducted semi-structured interviews and focus group discussions to assess perceptions on acceptability and feasibility of implementing BPaL. We determined the proportions of a recoded 3-point Likert scale (acceptable; neutral; unacceptable), as well as the overall likelihood of implementing BPaL (likely; neutral; unlikely) that participants graded per regimen, pre-defined aspect and country. We analysed the qualitative results using a deductive framework analysis. RESULTS: In total 188 stakeholders participated in this study: 63 from Kyrgyzstan, 51 from Indonesia, and 74 from Nigeria The majority were health care workers (110). Overall, 88% (146/166) of the stakeholders would likely implement BPaL once available. Overall acceptability for BPaL was high, especially patient friendliness was often rated as acceptable (93%, 124/133). In contrast, patient friendliness of the ITR was rated as acceptable by 45%. Stakeholders appreciated that BPaL would reduce workload and financial burden on the health care system. However, several stakeholders expressed concerns regarding BPaL safety (monitoring), long-term efficacy, and national regulatory requirements regarding introduction of the regimen. Stakeholders stressed the importance of addressing current health systems constraints as well, especially in treatment and safety monitoring systems. CONCLUSIONS: Acceptability and feasibility of the BPaL regimen is high among TB stakeholders in Indonesia, Kyrgyzstan, and Nigeria. The majority is willing to start using BPaL as the standard of care for eligible patients despite country-specific health system constraints.

Association of clinical factors and recent anticancer therapy with COVID-19 severity among patients with cancer: a report from the COVID-19 and Cancer Consortium.

BACKGROUND: Patients with cancer may be at high risk of adverse outcomes from severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. We analyzed a cohort of patients with cancer and coronavirus 2019 (COVID-19) reported to the COVID-19 and Cancer Consortium (CCC19) to identify prognostic clinical factors, including laboratory measurements and anticancer therapies. PATIENTS AND METHODS: Patients with active or historical cancer and a laboratory-confirmed SARS-CoV-2 diagnosis recorded between 17 March and 18 November 2020 were included. The primary outcome was COVID-19 severity measured on an ordinal scale (uncomplicated, hospitalized, admitted to intensive care unit, mechanically ventilated, died within 30 days). Multivariable regression models included demographics, cancer status, anticancer therapy and timing, COVID-19-directed therapies, and laboratory measurements (among hospitalized patients). RESULTS: A total of 4966 patients were included (median age 66 years, 51% female, 50% non-Hispanic white); 2872 (58%) were hospitalized and 695 (14%) died; 61% had cancer that was present, diagnosed, or treated within the year prior to COVID-19 diagnosis. Older age, male sex, obesity, cardiovascular and pulmonary comorbidities, renal disease, diabetes mellitus, non-Hispanic black race, Hispanic ethnicity, worse Eastern Cooperative Oncology Group performance status, recent cytotoxic chemotherapy, and hematologic malignancy were associated with higher COVID-19 severity. Among hospitalized patients, low or high absolute lymphocyte count; high absolute neutrophil count; low platelet count; abnormal creatinine; troponin; lactate dehydrogenase; and C-reactive protein were associated with higher COVID-19 severity. Patients diagnosed early in the COVID-19 pandemic (January-April 2020) had worse outcomes than those diagnosed later. Specific anticancer therapies (e.g. R-CHOP, platinum combined with etoposide, and DNA methyltransferase inhibitors) were associated with high 30-day all-cause mortality. CONCLUSIONS: Clinical factors (e.g. older age, hematological malignancy, recent chemotherapy) and laboratory measurements were associated with poor outcomes among patients with cancer and COVID-19. Although further studies are needed, caution may be required in utilizing particular anticancer therapies. CLINICAL TRIAL IDENTIFIER: NCT04354701.

Dynamics and risk of transmission of bovine tuberculosis in the emerging dairy regions of Ethiopia.

The Ethiopian government has several initiatives to expand and intensify the dairy industry; however, the risk of bovine tuberculosis (bTB) spread is a challenge. To assess the rate of expansion and risk factors for transmission of bTB within-herds, we carried out a repeated cross-sectional survey at two time points, 2016/17 and 2018, in three regional cities, namely, Gondar, Hawassa and Mekelle, representing the emerging dairy belts of Ethiopia. The total number of herds involved was 128, comprising an average of 2303 cattle in each round. The Single Intradermal Comparative Cervical Tuberculin (SICCT) test was used to identify reactor status and data on herd-level risk factors were collected using a structured questionnaire. In the first survey, the apparent prevalence of bTB, as measured by the SICCT test, was 4.5% (95% CI 3.7-5.4%) at the individual animal-level and 24% (95% CI 17.5-32%) at the herd-level. There was no statistically significant change in the overall apparent prevalence or regional distribution at the second survey, consistent with the infection being endemic. The incidence rate was estimated at 3.6 (95% CI 2.8-4.5) and 6.6 (95% CI 3.0-12.6) cases/100 cattle (or herd)-years at the animal- and herd-levels, respectively. Risk factors significantly associated with the within-herd transmission of bTB were age group and within-herd apparent prevalence at the start of the observation period. We noted that farmers voluntarily took steps to remove reactor cattle from their herds as a consequence of the information shared after the first survey. Removal of reactors between surveys was associated with a reduced risk of transmission within these herds. However, with no regulatory barriers to the sale of reactor animals, such actions could potentially lead to further spread between herds. We therefore advocate the importance of setting up regulations and then establishing a systematic bTB surveillance programme to monitor the impact prior to implementing any control measures in Ethiopia.

Higher Dosing of Rifamycins Does Not Increase Activity against Mycobacterium tuberculosis in the Hollow-Fiber Infection Model.

Improvements in the translational value of preclinical models can allow more-successful and more-focused research on shortening the duration of tuberculosis treatment. Although the hollow-fiber infection model (HFIM) is considered a valuable addition to the drug development pipeline, its exact role has not been fully determined yet. Since the strategy of increasing the dose of rifamycins is being evaluated for its treatment-shortening potential, additional in vitro modeling is important. Therefore, we assessed increased dosing of rifampin and rifapentine in our HFIM in order to gain more insight into the place of the HFIM in the drug development pipeline. Total and free-fraction concentrations corresponding to daily dosing of 2.7, 10, and 50 mg of rifampin/kg of body weight, as well as 600 mg and 1,500 mg rifapentine, were assessed in our HFIM using the Mycobacterium tuberculosis H37Rv strain. Drug activity and the emergence of drug resistance were assessed by CFU counting and subsequent mathematical modeling over 14 days, and pharmacokinetic exposures were checked. We found that increasing rifampin exposure above what is expected with the standard dose did not result in higher antimycobacterial activity. For rifapentine, only the highest concentration showed increased activity, but the clinical relevance of this observation is questionable. Moreover, for both drugs, the emergence of resistance was unrelated to exposure. In conclusion, in the simplest experimental setup, the results of the HFIM did not fully correspond to preexisting clinical data. The inclusion of additional parameters and readouts in this preclinical model could be of interest for proper assessment of the translational value of the HFIM.

Transthyretin amyloid deposits in lumbar spinal stenosis and assessment of signs of systemic amyloidosis.

BACKGROUND: Wild-type transthyretin (ATTRwt) amyloidosis is the most common systemic amyloidosis in Western countries and manifests mainly as progressive restrictive cardiomyopathy. OBJECTIVE: To study the prevalence of ATTR deposits in ligament tissue in patients undergoing surgery for lumbar spinal stenosis and to assess whether these deposits are associated with cardiac amyloidosis. MATERIALS AND METHODS: A total of 250 patients, aged 50-89 (57% women), none with known cardiovascular disease, were included. Ligaments were investigated microscopically for amyloid. ATTR type was determined by immunohistochemistry and fibril type by Western blot. The amount of amyloid was graded 0-4. All patients with grade 3-4 ATTR deposits were offered cardiac investigation including ECG, cardiac ultrasound, plasma NT-proBNP and cardiac magnetic resonance (CMR), including modern tissue characterization. RESULTS: Amyloid was identified in 221 of the samples (88.4%). ATTR appeared in 93 samples (37%) of whom 42 (17 women and 25 men) were graded 3-4; all had fibril type A (mixture of full-length TTR and fragmented TTR). Twenty-nine of 42 patients with grade 3-4 ATTR deposits accepted cardiovascular investigations; none of them had definite signs of cardiac amyloidosis, but five men had a history of carpal tunnel syndrome. CONCLUSIONS: The prevalence of ATTR deposits in ligamentum flavum in patients with lumbar spinal stenosis was high but not associated with manifest ATTR cardiac amyloidosis. However, the findings of fibril type A, the prevalence of previous carpal tunnel syndrome and ATTR amyloid in surrounding adipose and vascular tissue indicate that amyloid deposits in ligamentum flavum may be an early manifestation of systemic ATTR disease.

Allergic sensitisation in South Africa: Exploring regional variation in sensitisation.

BACKGROUND: Allergy is a common health problem in South Africa (SA), and a rational approach to allergy testing is essential to ensure cost-effective as well as optimal patient diagnosis and management. OBJECTIVES: To review allergy testing data with respect to current national testing recommendations, and to explore the regional variations in sensitisation. METHODS: Retrospective data review on allergy testing from a private pathology provider in SA over a 2-year period. Data on skin-prick testing (SPT) and allergen-specific IgE testing originating from all the provinces of SA were collected and analysed with regards to allergen positivity rate and regional sensitisation patterns. RESULTS: Among the patients (N=45 0320) tested for a suspected inhalant allergy, 46% tested positive. Only 45% of these received additional testing for the nine recommended inhalant allergens included in the current national testing protocol. Among the patients (N=6 775) who received SPT for a suspected inhalant allergy, 59% yielded one or more positive results. The most frequent sensitising allergens were house dust mite (Dermatophagoides pteronyssinus) and grass pollen. The house dust mite, Blomia tropicalis, was a significant sensitiser in coastal regions. SPT identified two other important regional allergens which are not included in the current recommendations for inhalant allergen-specific IgE testing. CONCLUSIONS: The current diagnostic recommendations include allergens that demonstrate significant sensitisation in all regions of SA. Two additional allergens that show significant regional sensitisation in the South African population were identified. These findings may aid the recommendations for the most appropriate and cost-effective approach to allergy testing of symptomatic patients in SA.

[Don't be guided purely by numbers: false increased TSH values due to analytical interference]. / Vaar niet alleen op een getal.

BACKGROUND: Physicians are often guided by laboratory values. When a clinical presentation does not match laboratory values, one must consider the possibility that these values may be falsely increased or decreased. A common cause is analytical interference. CASE DESCRIPTION: A 57-year-old male, presenting with fatigue and palpitations, had high TSH and normal FT4 values. Although there were no fitting clinical symptoms for these values, the patient was treated with levothyroxine assuming he had subclinical hypothyroidism. TSH levels remained high, however, whereas FT4 levels increased and the patient developed thyrotoxicosis. Eventually, it was discovered that the TSH was falsely elevated. CONCLUSION: The patient turned out to have macro TSH, where TSH forms conjunctions with IgG into larger molecules. These conjugates cause a rarely occurring interference during laboratory analysis, resulting in a falsely increased TSH value.

Effects and moderators of coping skills training on symptoms of depression and anxiety in patients with cancer: Aggregate data and individual patient data meta-analyses.

PURPOSE: This study evaluated the effects of coping skills training (CST) on symptoms of depression and anxiety in cancer patients, and investigated moderators of the effects. METHODS: Overall effects and intervention-related moderators were studied in meta-analyses of pooled aggregate data from 38 randomized controlled trials (RCTs). Patient-related moderators were examined using linear mixed-effect models with interaction tests on pooled individual patient data (n = 1953) from 15 of the RCTs. RESULTS: CST had a statistically significant but small effect on depression (g = -0.31,95% confidence interval (CI) = -0.40;-0.22) and anxiety (g = -0.32,95%CI = -0.41;-0.24) symptoms. Effects on depression symptoms were significantly larger for interventions delivered face-to-face (p = .003), led by a psychologist (p = .02) and targeted to patients with psychological distress (p = .002). Significantly larger reductions in anxiety symptoms were found in younger patients (pinteraction < 0.025), with the largest reductions in patients <50 years (ß = -0.31,95%CI = -0.44;-0.18) and no significant effects in patients ≥70 years. Effects of CST on depression (ß = -0.16,95%CI = -0.25;-0.07) and anxiety (ß = -0.24,95%CI = -0.33;-0.14) symptoms were significant in patients who received chemotherapy but not in patients who did not (pinteraction < 0.05). CONCLUSIONS: CST significantly reduced symptoms of depression and anxiety in cancer patients, and particularly when delivered face-to-face, provided by a psychologist, targeted to patients with psychological distress, and given to patients who were younger and received chemotherapy.

Results from the Netherlands' 2018 Report Card and Report Card+ on physical activity for children and youth with and without chronic medical condition.

OBJECTIVE: The objective of this study was to summarize the results of the 2018 the Netherlands' Physical Activity Report Card (PARC) for children and youth as well as for children and youth with a chronic medical condition (CMC; PARC+). STUDY DESIGN: This study is a survey. METHODS: A total of 12 indicators were graded using the Active Healthy Kids Global Alliance PARC development process, which includes a synthesis of the best available research, surveillance, policy and practice findings and expert consensus. Grades were based on the best available evidence and ranged from grade A (>80% of the children succeed) to grade F (less than 20% succeed) or incomplete (INC). Sources included national surveys, peer-reviewed literature and grey literature such as government and non-government reports and online content. RESULTS: Grades assigned for PARC/PARC+ were as follows: Overall Physical Activity: C-/D+; Organized Sports Participation: B/B-; Active Play: D/D; Active Transportation: A-/B+; Sedentary Behaviour: D/D; Physical Fitness: INC /INC; Family and Peers: C/INC; School: C+/A-; Community and Environment: INC /INC; Government: INC /INC; Sleep: A-/B+ and Weight Status: A-/A-, respectively. CONCLUSIONS: The report shows that the Netherlands' youth scores well on (organized) participation in sports and active transport to and from school. However, they do not participate enough in overall physical activity. Despite the fact that outdoor play is the most important exercise activity for children, outdoor play scores an insufficient score for both healthy children and children with a CMC. Sports participation also contributed significantly to daily physical activity. However, sports participation alone is not enough to comply with the national activity guidelines.

Copeptin and mid-regional pro-atrial natriuretic peptide in women with suspected or confirmed pre-eclampsia: comparison with sFlt-1/PlGF ratio.

OBJECTIVES: Arginine vasopressin (AVP) and atrial natriuretic peptide (ANP) may contribute to the pathogenesis of pre-eclampsia (PE), but their role remains to be elucidated. Our aims were to evaluate the surrogates of AVP and ANP, C-terminal pro-AVP (copeptin) and mid-regional pro-ANP (MR-proANP), as biomarkers for the prediction of PE-related pregnancy complications and whether they are associated with angiogenic markers and/or clinical manifestations of PE. METHODS: This was a retrospective analysis of a prospective cohort study that enrolled pregnant women with suspected or confirmed PE, between December 2013 and April 2016. From each patient, a blood sample was obtained at study entry and serum levels of copeptin, MR-proANP, soluble fms-like tyrosine kinase-1 (sFlt-1) and placental growth factor (PlGF) were measured. We evaluated the ability of sFlt-1, PlGF, sFlt-1/PlGF ratio, copeptin and MR-proANP, assessed either alone or combined with traditional predictors (gestational age, parity, diastolic blood pressure and proteinuria), to predict maternal complications and fetal/neonatal complications. Models were compared using concordance statistic (C-index). RESULTS: A total of 526 women were evaluated in the study. Women with confirmed PE displayed elevated serum copeptin and MR-proANP levels in comparison to those with suspected PE but no hypertensive disease of pregnancy. When combined with traditional predictors, the sFlt-1/PlGF ratio displayed a higher C-index than copeptin and MR-proANP (0.76, 0.63 and 0.67, respectively, vs 0.60 for the traditional predictors alone) for the prediction of maternal complications. Similarly, for the prediction of fetal/neonatal complications, the sFlt-1/PlGF ratio displayed a higher C-index than copeptin and MR-proANP when added to the traditional model (0.83, 0.79 and 0.80, respectively, vs 0.79 for the traditional predictors alone). When subdividing women according to sFlt-1/PlGF ratio (≥ 85 vs < 85), no differences in copeptin levels were observed, while MR-proANP level was elevated in women with sFlt-1/PlGF ratio ≥ 85. Multiple regression analysis revealed that copeptin and MR-proANP were independent determinants of proteinuria. CONCLUSIONS: Copeptin and MR-proANP have limited value in predicting PE-related complications when compared with the sFlt-1/PlGF ratio. However, both copeptin and MR-proANP were associated with proteinuria, with copeptin exerting this effect independently of the sFlt-1/PlGF ratio. Copyright © 2020 ISUOG.
