RESUMO
BACKGROUND: The intestinal protozoan parasite Cryptosporidium is an important cause of diarrheal disease worldwide. A national microbiological surveillance programme was implemented in Sweden in 2018 in order to increase knowledge of the molecular epidemiology of human cryptosporidiosis to better understand transmission patterns and potential zoonotic sources. This article summarises the results of the first five years of the surveillance programme. METHODS: Cryptosporidium-positive faecal and DNA samples from domestically acquired infections were collected from clinical microbiological laboratories in Sweden. Species and subtype determination was performed using 60 kDa glycoprotein and/or small subunit ribosomal RNA gene analysis. RESULTS: Between 2018 and 2022, 1654 samples were analysed and 11 different species were identified: C. parvum (n = 1412), C. mortiferum (n = 59), C. hominis (n = 56), C. erinacei (n = 11), C. cuniculus (n = 5), C. meleagridis (n = 3), C. equi (n = 2), C. ubiquitum (n = 2), and one each of C. canis, C. ditrichi and C. felis. Subtyping revealed seven subtype families of C. parvum (new subtype families IIy and IIz) and 69 different subtypes (11 new subtypes). The most common C. parvum subtypes were IIdA22G1c, IIdA24G1, IIdA15G2R1 and IIaA16G1R1b. For C. hominis, four different subtype families and nine different subtypes (two new subtypes) were identified. For additional species, two new subtype families (IIIk and VId) and nine new subtypes were identified. All successfully subtyped C. mortiferum cases were subtype XIVaA20G2T1, confirming previous findings in Sweden. Several outbreaks were identified of which the majority were foodborne and a few were due to direct contact with infected animals. CONCLUSION: Infection with C. parvum is the leading cause of human cryptosporidiosis acquired in Sweden, where more than 90% of domestic cases are caused by this zoonotic species and only a small proportion of cases are due to infection with other species. The rodent-associated C. mortiferum is considered an emerging zoonotic species in Sweden and the number of domestically acquired human cases has surpassed that of infection with C. hominis. A high diversity of species and subtypes, as well as diversity within the same subtype, was detected. Also, cryptosporidiosis appears to affect adults to a great extent in Sweden.

BACKGROUND: Pregnancy-related venous thromboembolism is a leading cause of maternal morbidity and mortality, and thromboprophylaxis is indicated in pregnant and post-partum women with a history of venous thromboembolism. The optimal dose of low-molecular-weight heparin to prevent recurrent venous thromboembolism in pregnancy and the post-partum period is uncertain. METHODS: In this open-label, randomised, controlled trial (Highlow), pregnant women with a history of venous thromboembolism were recruited from 70 hospitals in nine countries (the Netherlands, France, Ireland, Belgium, Norway, Denmark, Canada, the USA, and Russia). Women were eligible if they were aged 18 years or older with a history of objectively confirmed venous thromboembolism, and with a gestational age of 14 weeks or less. Eligible women were randomly assigned (1:1), before 14 weeks of gestational age, using a web-based system and permuted block randomisation (block size of six), stratified by centre, to either weight-adjusted intermediate-dose or fixed low-dose low-molecular-weight heparin subcutaneously once daily until 6 weeks post partum. The primary efficacy outcome was objectively confirmed venous thromboembolism (ie, deep-vein thrombosis, pulmonary embolism, or unusual site venous thrombosis), as determined by an independent central adjudication committee, in the intention-to-treat (ITT) population (ie, all women randomly assigned to treatment). The primary safety outcome was major bleeding which included antepartum, early post-partum (within 24 h after delivery), and late post-partum major bleeding (24 h or longer after delivery until 6 weeks post partum), assessed in all women who received at least one dose of assigned treatment and had a known end of treatment date. This study is registered with ClinicalTrials.gov, NCT01828697, and is now complete. FINDINGS: Between April 24, 2013, and Oct 31, 2020, 1339 pregnant women were screened for eligibility, of whom 1110 were randomly assigned to weight-adjusted intermediate-dose (n=555) or fixed low-dose (n=555) low-molecular-weight heparin (ITT population). Venous thromboembolism occurred in 11 (2%) of 555 women in the weight-adjusted intermediate-dose group and in 16 (3%) of 555 in the fixed low-dose group (relative risk [RR] 0·69 [95% CI 0·32-1·47]; p=0·33). Venous thromboembolism occurred antepartum in five (1%) women in the intermediate-dose group and in five (1%) women in the low-dose group, and post partum in six (1%) women and 11 (2%) women. On-treatment major bleeding in the safety population (N=1045) occurred in 23 (4%) of 520 women in the intermediate-dose group and in 20 (4%) of 525 in the low-dose group (RR 1·16 [95% CI 0·65-2·09]). INTERPRETATION: In women with a history of venous thromboembolism, weight-adjusted intermediate-dose low-molecular-weight heparin during the combined antepartum and post-partum periods was not associated with a lower risk of recurrence than fixed low-dose low-molecular-weight heparin. These results indicate that low-dose low-molecular-weight heparin for thromboprophylaxis during pregnancy is the appropriate dose for the prevention of pregnancy-related recurrent venous thromboembolism.

PURPOSE: Existing evidence estimates a twofold risk of venous thromboembolisms (VTEs) if tourniquet is applied during total knee arthroplasties (TKAs). However, this estimate relies on multiple trials with a low number of patients analyzing VTEs as a secondary outcome. We hypothesized that tourniquet-use increases the risk of symptomatic VTE within 90 days of contemporary primary TKA and aimed to use the extensive Danish healthcare registries to quantify this risk. METHODS: Prospectively collected registry data from Danish patients receiving primary TKAs between 2014 and 2018 were included in the study. Patients were divided by tourniquet-use during surgery. By merging information from four nationwide registries, the study included 44 baseline characteristics with the potential to confound the association between tourniquet-use and VTE. Incidence rate and odds ratios were used to compare the risk of VTE within 90 days of surgery. RESULTS: 19,804 patients of whom 10,111 (51%) were operated with tourniquet and 9693 (49%) without were included. The mean age (SD) was 70 (9) in both groups and 62% were females in the tourniquet group compared with 61% in the no tourniquet group. The groups were similarly comparable across all other baseline characteristics except type of post-operative thromboprophylaxis, type of anaesthesia, implant fixation, and year of surgery. The 90-days incidence of VTE was 0.77% (95% CI 0.60-0.94) in the tourniquet group compared with 1.10% (95% CI 0.90-1.31) in the no tourniquet group. Following adjustment for the unbalanced confounders, the odds ratio for VTE was 0.77 (95% CI 0.54-1.10) associated with tourniquet-use. CONCLUSION: In contemporary TKAs the rate of VTE within 90 days is low and not significant altered by tourniquet-use. Thus, tourniquet can safely be applied during primary TKA-surgery without jeopardizing the risk of postoperative VTE. LEVEL OF EVIDENCE: II-prospective cohort study.

Functional antibody deficiency is clinically assessed from antibody responses to vaccination. However, diagnostic vaccination is complex and may fail in practice. We hypothesized that the levels of naturally occurring antibodies against galactose-α-1,3-galactose (αGal) may represent alternative markers of functional antibody capacity. We included data from 229 patients with suspected primary immunodeficiency in a retrospective study. Antibody levels against αGal and twelve pneumococcal serotypes were determined with solid-phase immunoassays. Pneumococcal vaccinations and treatment with normal human immunoglobulin were assessed from medical records. Anti-αGal antibody levels correlated positively with anti-pneumococcal antibody levels measured before and after pneumococcal vaccination. Contrary to the anti-pneumococcal antibody levels, the anti-αGal antibody level showed potential for predicting subsequent immunoglobulin treatment - a marker of disease severity. Naturally occurring antibodies may reflect the functional capacity tested by diagnostic vaccination but add more useful clinical data. The clinical utility of this easy test should be evaluated in prospective studies.

BACKGROUND: The time interval from first symptom and sign until a cancer diagnosis significantly affects the prognosis. Therefore, recognising and acting on signs of cancer, such as anaemia, is essential. Evidence is sparse on the overall risk of cancer and the risk of specific cancer types in persons with new-onset anaemia detected in an unselected general practice population. We aimed to assess the risk of cancer in persons with new-onset anaemia detected in general practice, both overall and for selected cancer types. METHODS: This observational population-based cohort study used individually linked electronic data from laboratory information systems and nationwide healthcare registries in Denmark. We included persons aged 40-90 years without a prior history of cancer and with new-onset anaemia (no anaemia during the previous 15 months) detected in general practice in 2014-2018. We measured the incidence proportion and standardised incidence ratios of a new cancer diagnosis (all cancers except for non-melanoma skin cancers) during 12 months follow-up. RESULTS: A total of 48,925 persons (median [interquartile interval] age, 69 [55-78] years; 55.5% men) were included in the study. In total, 7.9% (95% confidence interval (CI): 7.6 to 8.2) of men and 5.2% (CI: 4.9 to 5.5) of women were diagnosed with cancer during 12 months. Across selected anaemia types, the highest cancer incidence proportion was seen in women with 'anaemia of inflammation' (15.3%, CI: 13.1 to 17.5) (ferritin > 100 ng/mL and increased C-reactive protein (CRP)) and in men with 'combined inflammatory iron deficiency anaemia' (19.3%, CI: 14.5 to 24.1) (ferritin < 100 ng/mL and increased CRP). For these two anaemia types, the cancer incidence across cancer types was 10- to 30-fold higher compared to the general population. CONCLUSIONS: Persons with new-onset anaemia detected in general practice have a high cancer risk; and markedly high for 'combined inflammatory iron deficiency anaemia' and 'anaemia of inflammation'. Anaemia is a sign of cancer that calls for increased awareness and action. There is a need for research on how to improve the initial pathway for new-onset anaemia in general practice.

In autumn 2019, the Public Health Agency of Sweden identified a cluster of Salmonella Newport cases by whole genome sequencing (WGS). Cases' distribution in place and time indicated a nation-wide ongoing outbreak. An investigation was initiated to identify the source and prevent further cases. We conducted a case-case study based on notified salmonellosis cases and a Salmonella trawling questionnaire, comparing 20 outbreak cases and 139 control cases. Food exposures were compared by adjusted odds ratios (aOR) with 95% confidence interval (CI) using logistic regression. Implicated foods were sampled. Outbreak cases were more likely to have consumed crayfish (aOR = 26; 95% CI: 6.3-105). One specific brand of imported frozen, pre-cooked whole crayfish in dill brine was identified as the source. Salmonella Newport was later detected in different batches from retail and in one sample from border control. Isolates from food samples clustered with the human outbreak strain by WGS. Although the retailer made a complete recall, two more cases were identified long afterwards. This investigation demonstrated the successful use of a case-case study and targeted microbiological testing to identify the source. The immediate action taken by the retailer was important to confirm the source and stop the outbreak.

BackgroundVibriosis cases in Northern European countries and countries bordering the Baltic Sea increased during heatwaves in 2014 and 2018.AimWe describe the epidemiology of vibriosis and the genetic diversity of Vibrio spp. isolates from Norway, Sweden, Denmark, Finland, Poland and Estonia in 2018, a year with an exceptionally warm summer.MethodsIn a retrospective study, we analysed demographics, geographical distribution, seasonality, causative species and severity of non-travel-related vibriosis cases in 2018. Data sources included surveillance systems, national laboratory notification databases and/or nationwide surveys to public health microbiology laboratories. Moreover, we performed whole genome sequencing and multilocus sequence typing of available isolates from 2014 to 2018 to map their genetic diversity.ResultsIn 2018, we identified 445 non-travel-related vibriosis cases in the study countries, considerably more than the median of 126 cases between 2014 and 2017 (range: 87-272). The main reported mode of transmission was exposure to seawater. We observed a species-specific geographical disparity of vibriosis cases across the Nordic-Baltic region. Severe vibriosis was associated with infections caused by Vibrio vulnificus (adjOR: 17.2; 95% CI: 3.3-90.5) or Vibrio parahaemolyticus (adjOR: 2.1; 95% CI: 1.0-4.5), age ≥ 65 years (65-79 years: adjOR: 3.9; 95% CI: 1.7-8.7; ≥â¯80 years: adjOR: 15.5; 95% CI: 4.4-54.3) or acquiring infections during summer (adjOR: 5.1; 95% CI: 2.4-10.9). Although phylogenetic analysis revealed diversity between Vibrio spp. isolates, two V. vulnificus clusters were identified.ConclusionShared sentinel surveillance for vibriosis during summer may be valuable to monitor this emerging public health issue.

OBJECTIVE: To assess the ability of ultrasound to predict successful tapering and successful discontinuation of biological DMARDs (bDMARDs) at the 2-year follow-up in RA patients in sustained remission. METHODS: Patients in sustained remission (DAS28-CRP ≤ 2.6) and with no radiographic progression the previous year tapered bDMARDs according to a standardized regime. A total of 119 of these patients were included in this ultrasound substudy. At baseline, clinical assessment, MRI, X-ray and ultrasound of 24 joints were performed. Ultrasound-detected synovitis was defined and scored 0-3 using the OMERACT scoring system at the joint level for both grey-scale and Doppler activity. Sum scores for each ultrasound modality were calculated for 24 joints at the patient level. The final state of treatment was assessed after 2 years. The predictive value of ultrasound measures for successful tapering and discontinuation at the 2-year follow-up was assessed via logistic regression analyses. RESULTS: Negative IgM-RF [odds ratio (OR) = 0.29, 95% CI: 0.10-0.85; P = 0.024] and lower Doppler sum score of 24 joints (OR = 0.44, 95% CI: 0.15, 0.87; P = 0.014) were independent predictors for successful discontinuation of bDMARDs at the 2-year follow-up. The predictive value of the Doppler sum score was independent of MRI findings. Previous numbers of bDMARDs were predictive of successful tapering (OR = 0.58, 95% CI: 0.35, 0.91; P = 0.018), whereas ultrasound was not. Clinical parameters were not predictive of successful tapering/discontinuation. CONCLUSION: Doppler sum score was an independent predictor for successful discontinuation of bDMARDs at the 2-year follow-up-the odds for achieving successful discontinuation decreased by 56% per one-unit increase in Doppler sum score. Ultrasound could not predict successful tapering.

BACKGROUND: Anaemia is associated with adverse outcomes, including increased morbidity and all-cause mortality. Diagnostic workup of patients with anaemia is essential to detect underlying disease, especially undiagnosed malignancy. OBJECTIVE: To describe the cancer-relevant diagnostic workup in patients with new-onset anaemia detected in general practice. An additional aim was to analyse associations between patient characteristics and the diagnostic workup. DESIGN: Observational population-based cohort study using electronic laboratory and register data. SETTING: Danish general practice. SUBJECTS: Patients aged 40-90 years with new-onset anaemia (no anaemia in the preceding 15 months) detected in general practice. Patients were identified in Danish laboratory information systems and nationwide registries in 2014-2018. MAIN OUTCOME MEASURES: We measured the proportion of patients receiving predefined diagnostic investigations, that is, cancer patient pathway, colonoscopy, gastroscopy, computerised tomography (CT) scan, faecal test for haemoglobin, and bone marrow examination within three months of the anaemia index date. RESULTS: We included 59,993 patients, and around half of the patients with 'iron deficiency anaemia', 'anaemia of inflammation', or 'combined inflammatory iron deficiency anaemia' had no cancer-relevant diagnostic investigations performed. Patients aged 60-79 years and patients with severe anaemia were more likely to have investigations performed, while patients with comorbidity were less likely to have investigations performed. CONCLUSION: Around half of the patients with anaemia subtypes that may indicate underlying cancer had no cancer-relevant diagnostic investigations performed. This may represent missed diagnostic opportunities. Future interventions are needed to improve the diagnostic workup of cancer in patients with anaemia, for example, laboratory alert systems and clinical decision support.KEY POINTSThe general practitioners are often the first to detect anaemia and its underlying disease (e.g. undiagnosed malignancy).Large-scale studies are needed on the diagnostic workup of patients with anaemia in general practice in relation to an underlying malignancy.This study shows that the majority of patients with anaemia had no cancer-relevant diagnostic investigations performed, which may cause diagnostic delay.Interventions seems needed to improve the diagnostic workup of cancer in these patients to ensure timely diagnosis.

BACKGROUND: Anaemia can be a pointer of underlying severe disease, including undiagnosed malignancy. Subsequent blood tests are essential to classify the anaemia into subtypes and to facilitate targeted diagnostic investigation to ensure timely diagnosis of underlying disease. OBJECTIVE: We aimed to describe and classify anaemia based on laboratory tests from patients with new-onset anaemia detected in general practice. An additional aim was to analyse associations between patient characteristics and unclassified anaemia (not classifiable according to an algorithm). DESIGN: Population-based cross-sectional study. SETTING: Danish general practice. SUBJECTS: A total of 62,731 patients (age: 40-90 years) with new-onset anaemia were identified in Danish laboratory information systems and nationwide registries, and data were obtained for 2014-2018. MAIN OUTCOME MEASURES: We measured the proportion of patients classified into subtypes of anaemia based on blood tests requested by general practitioners within 31 days of the anaemia index date. RESULTS: Of the 62,731 patients with new-onset anaemia, we identified unclassified anaemia in 78.9% (95% confidence interval (CI): 77.3-80.5) of men and 65.1% (CI: 63.4-66.9) of women. The likelihood of unclassified anaemia increased with age, increasing comorbidity and decreasing severity of anaemia. CONCLUSION: The majority of patients with new-onset anaemia could not be classified through a simple algorithm due to missing blood tests, which highlights a potential missed opportunity for diagnosis. Standardised laboratory testing of patients with anaemia is warranted to ensure adequate follow-up and early detection of underlying severe disease.KEY POINTSAnaemia can be a sign of malignancy, and anaemia classification is an important step in the diagnosis of underlying disorders.The majority of patients with anaemia could not be classified according to a simple algorithm due to missing blood tests.Some patient characteristics were associated with a high risk of unclassified anaemia: high age, high comorbidity, and severe anaemia.Standardised laboratory testing in patients with anaemia is needed to inform targeted diagnostic investigation to ensure timely diagnosis.

Sweden is investigating an outbreak of monophasic Salmonella Typhimurium. Eighty-two nationally-distributed cases have been confirmed, with date of symptom onset between 28 August and 29 October. Cases were 51 years of age on average (range: 0-89) and the majority of cases were female (62%). A case-control study was conducted and suggested small tomatoes as source of the outbreak (adjusted odds ratio (OR): 10.8, 95% confidence interval (CI): 4.15-112.68, p valueâ¯<â¯0.001), and a trace-back investigation led to a single, non-Swedish producer in Europe. Both the Salmonella strain and the source of the outbreak are rarely encountered in Europe. Results from investigation at the producer are pending.

BACKGROUND: Meeting psychosocial needs is a significant component of quality dementia care. To enable persons with dementia to live at home for as long as possible, a community healthcare service offering care where physical, social, psychological, cultural and spiritual needs are met, is recommended. A comprehensive allocation process is required to allocate individually tailored healthcare services. However, the allocation process for older home-dwelling persons with dementia, specifically for services to safeguard psychosocial needs, remains largely unexplored. Accordingly, this study aims to explore purchasers' deliberations on psychosocial needs during the process of allocating healthcare services to older home-dwelling persons with dementia. METHODS: The study had a descriptive design with a qualitative approach. The primary data source was focus group interviews with purchasers who assess and allocate healthcare services. The interview data were supplemented by a review of administrative decisions made by the purchasers. Data from the focus group interviews were analysed using a descriptive and interpretive approach. Content analysis of the administrative decisions was conducted. RESULTS: The purchasers described the allocation process as challenging. The following four themes reflect the complexity of the allocation process: (i) an unfamiliar and unclear concept; (ii) a hierarchy of needs; (iii) an adjusting allocation process; (iv) a challenging documentation of administrative decisions. CONCLUSIONS: The purchasers viewed a comprehensive allocation process as important. However, a web of different interplaying aspects prevented the purchasers from conducting a comprehensive need-led allocation process. Insufficient assessment or allocation threatens the adequate safeguarding of the psychosocial needs of persons with dementia. Having varied and sufficient services to allocate is of great importance, but is not sufficient. Psychosocial needs must be better incorporated as a significant element throughout the entire allocation process.

In Denmark, biennial population screening for colorectal cancer was introduced in 2014 for all aged 50-74 years. Five laboratories representative for the regional division of Denmark perform the immunochemical testing of faecal occult blood in the screening samples (iFOBT, OC-Sensor (Eiken Chemical, cut-off 100 µg/L)). In July 2016, a new agreement on the public post-delivery entailed an increased lag time (five days) from the screening participant drops the screening sample into a mail-box until sample arrival at the laboratories. Previous work had reported that a lag time above five days led to more false negative iFOBT tests. We investigated if this was true also under Danish conditions. We performed two stability tests; one with sample storage at 30 °C for 14 days (N = 60), and another with sample storage at room temperature for 13 days (N = 10). We extracted data from our laboratory information system (LABKA) on all iFOBT tests performed in the entire Central Denmark Region (N = 104,328 patients) during the last six months for each calendar year 2014-16. For each year, we computed the distribution of iFOBT tests below and above cut-off. Our stability tests showed no positive samples switching to false negative after storage; however, some negative samples turned false positive, especially at 30 °C. The data showed no change in the distribution of iFOBT tests below and above cut-off after July 2016. We found no evidence that an enhanced lag time increased the number of false negative iFOBT tests in the Danish screening program for colorectal cancer.

BACKGROUND: The majority of persons with dementia are home-dwelling. To enable these persons to stay in their own homes as long as possible, a holistic, individual and flexible care is recommended. Despite a requirement for meeting psychological, social and physical needs, home care services seem to focus on patients' physical needs. Accordingly, the aim of this study was to explore how the psychosocial needs of home-dwelling, older persons with dementia were perceived, emphasized and met by home care services. METHODS: A descriptive, qualitative approach was used. Data were collected through semi-structured focus group interviews with 24 health care providers in home care services from four municipalities. Data were analysed using systematic text condensation. RESULTS: This study showed major differences in how health care providers perceived the psychosocial needs of older home-dwelling persons with dementia and how they perceived their responsibilities for meeting those psychosocial needs. The differences in the health care providers' perceptions seemed to significantly influence the provided care. Three co-existing logics of care were identified: the physical need-oriented logic, the renouncement logic and the integrated logic. CONCLUSIONS: The differences in how health care providers perceived the psychosocial needs of persons with dementia and their responsibilities for meeting those needs, influenced how the psychosocial needs were met. These differences indicates a need for a clarification of how psychosocial needs should be conceptualized and who should be responsible for meeting these needs. Further, increased competence and increased consciousness of psychosocial needs and how those needs can be met, are essential for delivering high-quality holistic care that enables persons with dementia to live in their own home for as long as possible.

BACKGROUND: In the winter and spring of 2011 a large outbreak of cryptosporidiosis occurred in Skellefteå municipality, Sweden. This study summarizes the outbreak investigation in terms of outbreak size, duration, clinical characteristics, possible source(s) and the potential for earlier detection using calls to a health advice line. METHODS: The investigation included two epidemiological questionnaires and microbial analysis of samples from patients, water and other environmental sources. In addition, a retrospective study based on phone calls to a health advice line was performed by comparing patterns of phone calls between different water distribution areas. RESULTS: Our analyses showed that approximately 18,500 individuals were affected by a waterborne outbreak of cryptosporidiosis in Skellefteå in 2011. This makes it the second largest outbreak of cryptosporidiosis in Europe to date. Cryptosporidium hominis oocysts of subtype IbA10G2 were found in patient and sewage samples, but not in raw water or in drinking water, and the initial contamination source could not be determined. The outbreak went unnoticed to authorities for several months. The analysis of the calls to the health advice line provides strong indications early in the outbreak that it was linked to a particular water treatment plant. CONCLUSIONS: We conclude that an earlier detection of the outbreak by linking calls to a health advice line to water distribution areas could have limited the outbreak substantially.

BACKGROUND: Although a large number of people are diagnosed with dementia each year, the syndrome is still perceived as a sensitive and tabooed topic. Communication about dementia to those living with the syndrome and their relatives is often experienced as challenging by health professionals. Failure to communicate clearly may threaten assessment and allocation of appropriate, effective healthcare services. Accordingly, the aim of this study was to explore how purchasers, assessing and allocating healthcare services to home-dwelling older people with dementia, described challenges in communicating about dementia with those with the syndrome and their relatives. Furthermore, the study aimed to explore the purchasers' justifications for their choice of words. METHODS: A qualitative study was conducted to investigate two data sources: focus group interviews with purchasers assessing need for healthcare services, and a review of administrative decisions written by those allocating services. Focus group data were explored using an interpretive approach and qualitative content analysis was carried out with the administrative decisions. RESULTS: The purchasers found it challenging to talk and write about dementia to those with the syndrome and their relatives when assessing and allocating services. The purchasers were flexible in their communication and aimed to be open when talking and writing about dementia. However, euphemisms and omission were used extensively. Four justifications for the chosen verbal and written language were identified: avoiding disclosure; protecting the person with dementia; protecting the relatives/avoiding conflict; and last, taboo and stigma. CONCLUSIONS: Despite purchasers experiencing difficulties in communicating about dementia to those with the syndrome and their relatives, they did manage to communicate in a conscious and flexible way. The purchasers had several justifications for their language choice. However, extensive use of euphemisms and omission might threaten appropriate identification of needs and provision of high quality healthcare services. The challenges experienced by the purchasers demonstrate the need to focus on appropriate and flexible strategies for individually-tailored communication about dementia with people living with the syndrome.

BACKGROUND: Many patients are diagnosed with postoperative urine retention in the recovery room and treated with in-out catheterisation (IOC). OBJECTIVES: We hypothesised that the use of IOC could be reduced by mobilising patients to the toilet to pass urine instead of offering a bedpan or urinal. DESIGN: A randomised, controlled, nonblinded study with two groups. SETTING: University Hospital, October 2009 to June 2012. PATIENTS: One hundred and fifty-two patients scheduled for surgery for cervical or lumbar disc herniation. Inclusion criteria were a bladder volume more than 350âml and/or the need to pass urine in the recovery room. INTERVENTIONS: Participants were randomised in the recovery room for mobilisation to the toilet (Group I) or use of a bedpan or urinal in the bed (Group C). MAIN OUTCOME MEASURES: The number of IOC cases in the recovery room (primary outcome) and the duration of stay in the recovery room. RESULTS: Thirteen of 67 patients (19%) in Group I and 38 of 71 patients in Group C (54%) required IOC (Pâ<â0.001). The median (IQR) durations of stay in the RR were 125 (97 to 125) min in Group I and 157 (115 to 214) min in Group C (Pâ=â0.006). The median times from arrival to first general ward mobilisation were 85 (37 to 139) min in Group I and 180 (118 to 245) min in Group C (Pâ<â0.001). CONCLUSION: Patients were mobilised early after disc herniation intervention to permit toilet visits in the recovery room. This strategy decreased the number of IOCs, duration of stay in the recovery room and time from arrival to first mobilisation in the general ward.

In November 2010, ≈27,000 (≈45%) inhabitants of Östersund, Sweden, were affected by a waterborne outbreak of cryptosporidiosis. The outbreak was characterized by a rapid onset and high attack rate, especially among young and middle-aged persons. Young age, number of infected family members, amount of water consumed daily, and gluten intolerance were identified as risk factors for acquiring cryptosporidiosis. Also, chronic intestinal disease and young age were significantly associated with prolonged diarrhea. Identification of Cryptosporidium hominis subtype IbA10G2 in human and environmental samples and consistently low numbers of oocysts in drinking water confirmed insufficient reduction of parasites by the municipal water treatment plant. The current outbreak shows that use of inadequate microbial barriers at water treatment plants can have serious consequences for public health. This risk can be minimized by optimizing control of raw water quality and employing multiple barriers that remove or inactivate all groups of pathogens.

OBJECTIVE: To investigate copeptin as a biomarker for small-for-gestational-age. METHODS: We conducted a nested case-control study on maternal copeptin levels measured in gestational week 12 and 19 and risk of small-for-gestational age. Cases were defined as pregnant women who delivered a small-for-gestational-age infant. Small-for-gestational age was defined as a birth weight - 22% or less than expected according to gestational age (n = 39). Controls were pregnant women who delivered a normal-weight infant (n = 119). The copeptin ultrasensitive Kryptor kit (BRAHMS) was used to determine copeptin in maternal serum. We established reference ranges for copeptin by 95% prediction intervals with 90% confidence intervals. Paired and unpaired t-tests were performed to test the null-hypothesis of no difference in copeptin levels within and between the groups. RESULTS: The reference intervals for copeptin in normal pregnancies were 1.24-5.51 pmol/L (90% confidence intervals on upper and lower limit were 1.13-1.37 and 5.00-6.08 pmol/L) at gestational week 12, and 1.30-5.09 pmol/L (90% confidence intervals were 1.19-1.42 and 4.65-5.57 pmol/L) at gestational week 19. Copeptin levels decreased from week 12-19 in cases (p = 0.02), whereas no change was observed in controls (p = 0.61). We found no difference in copeptin levels in cases compared to controls in gestational week 12 (p = 0.10) and week 19 (p = 0.81). CONCLUSION: The present study could not demonstrate copeptin as a novel biomarker for small-for-gestational-age.
