ABSTRACT

OBJECTIVES: Long-term results after sinus venosus defect (SVD) closure are sparse and many studies lack a proper control cohort. This nationwide cohort evaluated the long-term outcome after SVD surgery. METHODS: The study enrolled every surgical SVD correction from the nationwide hospital discharge registry (FHDR) and surgical registries of two tertiary centers. Patients with more complex congenital heart defects were excluded. Surgeries were performed from 1969 to 2019. Five sex and birth-year-matched controls per SVD patient were gathered from the general population. RESULTS: In total, 182 surgical SVD corrections were performed during the study period. The median age at the time of surgery was 8.3 years (range 0.06-75.7), and the majority (77.5%, n = 141) were under 18 years old. The median follow-up period was 18 years (range 0.1-53). There was no significant difference in mortality during the follow-up (logrank p = 0.62, MRR 0.78, 95% CI: 0.30-2.0). However, SVD patients had elevated risk for new-onset atrial fibrillation (RR 4.9, 95% CI: 2.2-10.9), heart failure (RR 4.0, 95% CI: 1.2-13.2), ischemic heart disease (4.3, 95% CI, 1.5-11.7), migraine (RR 3.6, 95% CI: 1.5-9.1) and sick sinus syndrome, II- or III-degree AV-block or pacemaker implantation (RR 11.3, 95% CI: 2.9-43.8). CONCLUSION: Young patients with SVD have an excellent survival prognosis after the surgery. Risk for sick sinus syndrome or conduction disorders, atrial fibrillation, and heart failure remains elevated in the long-term follow-up.

ABSTRACT

OBJECTIVE: Coronavirus disease 2019 has highlighted the lack of knowledge on aerosol exposure during respiratory activity and aerosol-generating procedures. This study sought to determine the aerosol concentrations generated by coughing to better understand, and to set a standard for studying, aerosols generated in medical procedures. METHODS: Aerosol exposure during coughing was measured in 37 healthy volunteers in the operating theatre with an optical particle sizer, from 40 cm, 70 cm and 100 cm distances. RESULTS: Altogether, 306 volitional and 15 involuntary coughs were measured. No differences between groups were observed. CONCLUSION: Many medical procedures are expected to generate aerosols; it is unclear whether they are higher risk than normal respiratory activity. The measured aerosol exposure can be used to determine the risk for significant aerosol generation during medical procedures. Considerable variation of aerosol generation during cough was observed between individuals, but whether cough was volitional or involuntary made no difference to aerosol production.

ABSTRACT

Donor sperm is widely used in infertility treatments. The purpose of the study was to investigate, whether use of donor sperm in intrauterine insemination (IUI) or in vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI) treatments affect maternal and perinatal risks compared with spontaneously conceived pregnancies or use of partner sperm in IUI, IVF or ICSI. We provide a systematic review and meta-analyses on the most clinically relevant obstetric and perinatal outcomes after use of donor sperm compared with partner sperm: hypertensive disorders of pregnancy, preeclampsia, low birth weight, and preterm birth. Our meta-analyses showed an increased risk for preeclampsia (pooled adjusted odds ratio (aOR) 1.77, 95% CI 1.26-2.48) and hypertensive disorders of pregnancy (pooled aOR 1.55, 95%, CI 1.20-2.00) in pregnancies resulting from IUI with donor sperm compared with IUI with partner sperm. No increased risk was seen for low birth weight or preterm birth after the use of donor sperm in IUI compared with the use of partner sperm in IUI. Subgroup analysis for singletons only did not change these results. The meta-analysis on low birth weight showed a lower risk after in IVF with donor sperm compared with IVF with partner sperm (pooled aOR 0.89, 95% CI 0.83-0.94). For hypertensive disorders of pregnancy, preeclampsia and preterm birth, no difference was found between IVF with donor sperm vs. partner sperm. Patients need to be informed about the moderately increased risk of hypertensive disorders of pregnancy and preeclampsia in pregnancies after IUI with donor sperm.

ABSTRACT

BACKGROUND: Recently, new non-alcohol-based hand disinfection formulae have come to the market. Although they have passed the EN1500 test, data on their clinical efficacy compared with alcohol-based hand rubs are scarce, mainly covering benzalkonium chloride (BAC). AIM: To test the efficacy of silver-polymer-based, lactic-acid-based and BAC-based hand disinfectant foams and an alcohol-based hand rub gel to reduce bacterial counts on the fingertips of healthcare workers working on hospital wards. METHODS: Each of the 84 participants tested one of the four products during their morning shift on a hospital ward using the 'fingertips on Petri dish' method before and after rubbing their hands with the product. After incubation, two independent readers assessed bacterial counts on the culture plates. FINDINGS: The alcohol-based hand rub efficiently reduced bacteria on testers' fingertips in the test situation, whereas the lactic-acid- and BAC-based disinfectants did not have any detectable efficacy. The silver-polymer-based formula had some effect but requires further study. CONCLUSION: Non-alcohol-based hand rubs require careful consideration and further study before they can be accepted for clinical use.

ABSTRACT

BACKGROUND: Isolation precautions are essential prevent spread of COVID-19 infection but may have a negative impact on inpatient care. The impact of these measures on non-COVID-19 patients remains largely unexplored. AIM: This study aimed to investigate diagnostic and treatment delays related to isolation precautions, the associated patient outcome, and the predisposing risk factors for delays. METHODS: This observational study was conducted in seven Helsinki region hospitals during the first wave of the COVID-19 pandemic in Finland. The study used data on all non-COVID-19 inpatients, who were initially isolated due to suspected COVID-19, to estimate whether isolation precautions resulted in diagnostic or treatment delays. RESULTS: Out of 683 non-COVID-19 patients, 33 (4.8%) had delays related to isolation precautions. Clinical condition deteriorated non-fatally in seven (1.0%) patients. The following events were associated with an increased risk of treatment or a diagnostic delay: more than three ward transfers (P = 0.025); referral to an incorrect speciality in the emergency department (P = 0.004); more than three SARS-CoV-2 RT-PCR tests performed (P = 0.022); and where cancer was the final diagnosis (P = 0.018). In contrast, lower respiratory tract symptoms (P = 0.013) decreased the risk. CONCLUSIONS: The use of isolation precautions for patients who did not have COVID-19 had minor negative effects on patient outcomes. The present study underlines the importance of targeting diagnostic efforts to patients with unspecified symptoms and to those with a negative SARS-CoV-2 test result. Thorough investigations to achieve an accurate diagnosis improves the prognosis of patients and facilitates appropriate targeting of hospital resources.

ABSTRACT

BACKGROUND: Wastewater-based monitoring represents a useful tool for antibiotic resistance surveillance. AIM: To investigate the prevalence and abundance of antibiotic resistance genes (ARGs) in hospital wastewater over time. METHODS: Wastewater from two hospitals in Finland (HUS1 and HUS2) was monitored weekly for nine weeks (weeks 25-33) in summer 2020. A high-throughput real-time polymerization chain reaction (HT-qPCR) system was used to detect and quantify 216 ARGs and genes associated with mobile genetic elements (MGEs), integrons, and bacteria causing hospital-acquired infections (HAIs), as well as the 16S rRNA gene. Data from HT-qPCR were analysed and visualized using a novel digital platform, ResistApp. Eight carbapenem resistance genes (blaGES, blaKPC, blaVIM, blaNDM, blaCMY, blaMOX, blaOXA48, and blaOXA51) and three genes associated with bacteria causing HAIs (Acinetobacter baumannii, Klebsiella pneumoniae, and Pseudomonas aeruginosa) were studied. FINDINGS: There was a significantly higher number of ARGs at both hospitals in weeks 27-30 (174-191 genes) compared to other sampling weeks (151-171 genes). Our analyses also indicated that the two hospitals, which used different amounts of antibiotics, had significantly different resistance gene profiles. Carbapenem resistance genes were more prevalent and abundant in HUS1 than HUS2. Across both hospitals, blaGES and blaVIM were the most prevalent and abundant. There was also a strong positive association between blaKPC and K. pneumoniae in HUS1 wastewater. CONCLUSION: Routine wastewater-based monitoring using ResistApp can provide valuable information on the prevalence and abundance of ARGs in hospitals. This helps hospitals understand the spread of antibiotic resistance in hospitals and identify potential areas for intervention.

ABSTRACT

Reports on real-world experience on efficacy of bezlotoxumab (BEZ) has been lacking thus far. We retrospectively studied the efficacy and safety of BEZ in preventing the recurrence of Clostridium difficile infection (CDI) in five university hospitals in Finland. Seventy-three percent of our 46 patients remained free of recurrence in the following 3 months and the performance remained as 71% effective also among immunocompromised patients. In severe CDI, BEZ prevented recurrence in 63% of cases. From our study patients, 78% had three or more known risk factors for recurrence of CDI. Eight of our patients were waiting for fecal microbiota transplantation but after stopping the antibiotics that were continued to prevent recurrence of CDI and after receiving BEZ, all remained free of recurrence and did not need the procedure. Success with BEZ as an adjunctive treatment in preventing recurrence of CDI in high-risk patients may be rated as high. Among a subgroup of our patients, those already evaluated to be in need of fecal microbiota transplantation, BEZ seems to be an alternative option.

ABSTRACT

STUDY QUESTION: What are the attitudes and expectations of past oocyte donors concerning contact with their donor offspring and contact between donor offspring and their own children? SUMMARY ANSWER: The large majority (95%) of open-identity oocyte donors, as well as voluntarily registered donors (registered before the Finnish 2007 ART law), expressed positive or neutral feelings towards contact with their donor offspring and mainly positive expectations towards contact between donor offspring and their own children. WHAT IS KNOWN ALREADY: Although there is a growing support for openness and identity-release programmes in gamete donation, there is not much knowledge on how donors feel about potential contact with their offspring. Most previous studies have investigated donor expectations with a relatively short follow-up time, using small samples or participants in voluntary donor linkage services. STUDY DESIGN, SIZE, DURATION: A retrospective cross-sectional survey of all women who had donated oocytes between 1990 and 2012 at three fertility clinics in Finland was carried out in 2013. A self-administered questionnaire was sent out to a total of 569 former oocyte donors. PARTICIPANTS/MATERIALS, SETTING, METHODS: In total, 428 former oocyte donors answered a questionnaire assessing experiences and attitudes related to donation (response rate 75.2%). In this study, 358 donors who were unknown to the recipient were included. The mean follow-up time after the donation was 11.2 years. Before 2008, donors were non-identifiable but could voluntarily consent to release their identifying information to their donor offspring. After 2008, persons born as a result of gamete donation can, from the age of 18, receive information identifying the donor. Altogether 290 respondents had participated in a donation programme in 1990-2007 (before the Finnish ART-law), and 68 participated after the enactment of the ART-law, enabling us to compare attitudes by type of legislation during donation. MAIN RESULTS AND THE ROLE OF CHANCE: Most voluntarily registered and open-identity donors welcomed or were neutral to potential contact with their donor offspring but were slightly more cautious towards contact between their own children and a donor-conceived child. Open-end comments revealed some ambiguity and uncertainty as to what to expect from such contact and feelings varied from neutral curiosity and interest to desire to meet the donor-conceived child. LIMITATIONS, REASON FOR CAUTION: It is not possible to assess whether the opinions of the study participants is representative of all donors in 1990-2012, as 25% of all contacted former donors did not respond to the survey. WIDER IMPLICATIONS OF THE FINDINGS: This study is one of only a few studies among oocyte donors to evaluate long-term psychosocial consequences of the donation and expectations towards contact with donor offspring, using a large sample. Results from this study show that persisting concerns about adverse outcomes of identity release policies are largely unwarranted, but there is a need to develop counselling practices and material for identity-release donors about how to prepare for and adjust to potential contact with donor offspring. STUDY FUNDING/COMPETING INTEREST(S): This study was supported by grants from the Medical Society Life and Health, and from the Otto A. Malm Foundation. The authors have no competing interests to report. TRIAL REGISTRATION NUMBER: N/A.

ABSTRACT

Difficulties in social communication are part of the phenotypic overlap between autism spectrum disorders (ASD) and schizophrenia. Both conditions follow, however, distinct developmental patterns. Symptoms of ASD typically occur during early childhood, whereas most symptoms characteristic of schizophrenia do not appear before early adulthood. We investigated whether overlap in common genetic influences between these clinical conditions and impairments in social communication depends on the developmental stage of the assessed trait. Social communication difficulties were measured in typically-developing youth (Avon Longitudinal Study of Parents and Children, N⩽5553, longitudinal assessments at 8, 11, 14 and 17 years) using the Social Communication Disorder Checklist. Data on clinical ASD (PGC-ASD: 5305 cases, 5305 pseudo-controls; iPSYCH-ASD: 7783 cases, 11 359 controls) and schizophrenia (PGC-SCZ2: 34 241 cases, 45 604 controls, 1235 trios) were either obtained through the Psychiatric Genomics Consortium (PGC) or the Danish iPSYCH project. Overlap in genetic influences between ASD and social communication difficulties during development decreased with age, both in the PGC-ASD and the iPSYCH-ASD sample. Genetic overlap between schizophrenia and social communication difficulties, by contrast, persisted across age, as observed within two independent PGC-SCZ2 subsamples, and showed an increase in magnitude for traits assessed during later adolescence. ASD- and schizophrenia-related polygenic effects were unrelated to each other and changes in trait-disorder links reflect the heterogeneity of genetic factors influencing social communication difficulties during childhood versus later adolescence. Thus, both clinical ASD and schizophrenia share some genetic influences with impairments in social communication, but reveal distinct developmental profiles in their genetic links, consistent with the onset of clinical symptoms.

ABSTRACT

OBJECTIVES: To assess the clinical use of panfungal PCR for diagnosis of invasive fungal diseases (IFDs). We focused on the deep tissue samples. METHODS: We first described the design of panfungal PCR, which is in clinical use at Helsinki University Hospital. Next we retrospectively evaluated the results of 307 fungal PCR tests performed from 2013 to 2015. Samples were taken from normally sterile tissues and fluids. The patient population was nonselected. We classified the likelihood of IFD according to the criteria of the European Organization for Research and Treatment of Cancer/Invasive Fungal Infections Cooperative Group and the National Institute of Allergy and Infectious Diseases Mycoses Study Group (EORTC/MSG), comparing the fungal PCR results to the likelihood of IFD along with culture and microscopy results. RESULTS: There were 48 positive (16%) and 259 negative (84%) PCR results. The sensitivity and specificity of PCR for diagnosing IFDs were 60.5% and 91.7%, respectively, while the negative predictive value and positive predictive value were 93.4% and 54.2%, respectively. The concordance between the PCR and the culture results was 86% and 87% between PCR and microscopy, respectively. Of the 48 patients with positive PCR results, 23 had a proven or probable IFD. CONCLUSIONS: Fungal PCR can be useful for diagnosing IFDs in deep tissue samples. It is beneficial to combine fungal PCR with culture and microscopy.

ABSTRACT

BACKGROUND: Faecal microbiota transplantation (FMT) is an effective treatment for recurrent Clostridium difficile infection. In short-term the treatment has been shown to be safe, however, there are no large, long-term follow-up studies looking into the potential adverse effects. AIM: To analyse the long-term effect of FMT treatment in patients with recurrent C. difficile infection and to compare the outcome to antibiotic treated patients. METHODS: Altogether 84 patients of which 45 received a FMT treatment and 39 served as controls receiving antibiotics for the infection were followed on average for 3.8 years. Their recovery and medical status was evaluated using a retrospective questionnaire, determining their quality of life, gastrointestinal symptoms and new diseases potentially related to the FMT. RESULTS: There was no difference in the incidence of severe diseases (inflammatory bowel disease, cancer, autoimmune disease, allergy, neurological diseases) between the patient groups. In addition, weight gain did not differ between treatment groups. The FMT treated patients reported that their bowel habits improved significantly faster, they had less irregular bowel function and less symptoms of upper GI-tract when compared to the patients treated with antibiotics. Significantly more patients in FMT-group reported that their mental health improved after the treatment. The willingness to receive FMT treatment for potential new C. difficile infection was significantly higher in both treatment groups compared to other treatment options. CONCLUSION: Our study highlights that FMT is a durable, safe and acceptable treatment option for patients with recurrent C. difficile infection also in long term, and it shows potential benefits over antimicrobial treatment.

ABSTRACT

BACKGROUND: Influenza A(H1N1) causes serious complications in immunocompromised patients. The efficacy of seasonal vaccination in these patients has been questioned. AIM: To describe two outbreaks of influenza A(H1N1) in immunocompromised patients. METHODS: Two outbreaks of influenza A(H1N1) occurred in our institution: on the kidney transplant ward in 2014 including patients early after kidney or simultaneous pancreas-kidney transplantation, and on the oncology ward in 2016 including patients receiving chemotherapy for malignant tumours. Factors leading to these outbreaks and the clinical efficacy of seasonal influenza vaccination were analysed. FINDINGS: Altogether 86 patients were exposed to influenza A(H1N1) during the outbreaks, among whom the seasonal influenza vaccination status was unknown in 10. Only three out of 38 vaccinated patients were infected with influenza A(H1N1), compared with 20 out of 38 unvaccinated patients (P = 0.02). The death of one out of 38 vaccinated patients was associated with influenza, compared with seven out of 38 unvaccinated patients (P = 0.06). Shared factors behind the two outbreaks included outdated facilities not designed for the treatment of immunosuppressed patients. Vaccination coverage among patients was low, between 40% and 70% despite vaccination being offered to all patients free of charge. Vaccination coverage of healthcare workers on the transplant ward was low (46%), but, despite high coverage on the oncology ward (92%), the outbreak occurred. CONCLUSION: Seasonal influenza vaccination was clinically effective with both a reduced risk of influenza infection and a trend towards reduced mortality in these immunocompromised patients. Several possible causes were identified behind these two outbreaks, requiring continuous awareness in healthcare professionals to prevent further outbreaks.

ABSTRACT

BACKGROUND: Approximately 50 000 oocyte donation (OD) treatment cycles are now performed annually in Europe and the US. OBJECTIVES: To ascertain whether the risk of adverse obstetric and perinatal/neonatal outcomes is higher in pregnancies conceived by OD than in pregnancies conceived by conventional in-vitro fertilisation (IVF)/intracytoplasmic sperm injection (ICSI) or spontaneously. SEARCH STRATEGY: A systematic search was performed in the PubMed, Cochrane and Embase databases from 1982-2016. Primary outcomes were hypertensive disorders of pregnancy, pre-eclampsia (PE), gestational diabetes mellitus, postpartum haemorrhage, caesarean section, preterm birth, low birthweight and small for gestational age. SELECTION CRITERIA: Inclusion criteria were original studies including at least five OD pregnancies with a control group of pregnancies conceived by conventional IVF/ICSI or spontaneous conception, and case series with >500 cases reporting one or more of the selected complications. Studies not adjusting for plurality were excluded. DATA COLLECTION AND ANALYSIS: Thirty-five studies met the inclusion criteria. A random-effects model was used for the meta-analyses. MAIN RESULTS: For OD pregnancies versus conventional IVF/ICSI pregnancies the risk of PE was adjusted odds ratio (AOR) 2.11 (95% CI, 1.42-3.15) in singleton and AOR 3.31 (95% CI, 1.61-6.80) in multiple pregnancies. The risks of preterm birth and low birthweight in singletons were AOR 1.75 (95% CI, 1.39-2.20) and 1.53 (95% CI, 1.16-2.01), respectively. CONCLUSIONS: OD conceptions are associated with adverse obstetric and neonatal outcomes. To avoid the additional increase in risk from multiplicity, single-embryo transfer should be the choice of option in OD cycles. TWEETABLE ABSTRACT: Oocyte donation pregnancies have increased risk of a range of obstetric and neonatal complications.

ABSTRACT

Parainfluenza virus (PIV) can cause serious infections after hematopoietic stem cell or lung transplantation. Limited data exist about PIV infections after kidney transplantation. We describe an outbreak of PIV-3 in a transplant unit. During the outbreak, 45 patients were treated on the ward for postoperative care after kidney or simultaneous pancreas-kidney (SPK) transplantation. Overall, 29 patients were tested for respiratory viruses (12 patients with respiratory symptoms, 17 asymptomatic exposed patients) from nasopharyngeal swabs using polymerase chain reaction. PIV-3 infection was confirmed in 12 patients. One patient remained asymptomatic. In others, symptoms were mostly mild upper respiratory tract symptoms and subsided within a few days with symptomatic treatment. Two patients suffered from lower respiratory tract symptoms (dyspnea, hypoxemia, pulmonary infiltrates in chest computed tomography) and required supplemental oxygen. Four of six SPK patients and eight of 39 of kidney transplant patients were infected with PIV (p = 0.04). In patients with follow-up tests, PIV-3 shedding was still detected 11-16 days after diagnosis. Despite rapid isolation of symptomatic patients, PIV-3 findings were diagnosed within 24 days, and the outbreak ceased only after closing the transplant ward temporarily. In conclusion, PIV-3 infections early after kidney or SPK transplantation were mostly mild. PIV-3 easily infected immunosuppressed transplant recipients, with prolonged viral shedding.

ABSTRACT

BACKGROUND: The most severe manifestations of prostate biopsy complications are bacteremic infections. These complications are increasing alarmingly. METHODS: A retrospective cohort study of 17 183 transrectal prostate biopsies performed at the Helsinki and Uusimaa hospital district in southern Finland during 2005-2013. Biopsies were linked to a database of positive blood cultures, yielding 111 bacteremic cases, and yearly bacteremia rates were determined. By multiple regression analysis, demographic risk factors of the whole biopsy cohort for developing bacteremia or fluoroquinolone (FQ)-resistant bacteremia were studied. Clinical risk factors for bacteremia caused by an FQ-resistant organism and for serious bacteremic outcomes were studied by univariate and multivariate analyzes. RESULTS: The average bacteremia rate was 0.7% (111 of 17 183 biopsies) and an increase was observed from 0.5% in 2005 (95% confidence interval (CI): 0.3-0.9) to 1.2% in 2012 (95% CI 0.8-1.8); 53.2% were caused by an FQ-resistant organism. In univariate regression analysis, previous biopsy sessions and increasing calendar year of biopsy associated with the risk of developing bacteremia (odds ratio (OR) 1.232, 95% CI: 1.020-1.488, P=0.030 and OR 1.164, 95% CI: 1.079-1.255, P<0.001, respectively), but only increasing calendar year of biopsy remained statistically significant (OR 1.155, 95% CI: 1.070-1.247, P<0.001) in multivariate analysis. Foreign travel within 3 months was associated with FQ resistance in multivariate analysis (OR 7.158, 95% CI: 1.042 to infinite, P=0.045). The study failed to show any significant clinical risk factors for serious bacteremic outcomes (requiring intensive care, developing deep infection foci or death). CONCLUSIONS: The postbiopsy bacteremia rate doubled during the study period and half of the cases were caused by FQ-resistant organisms. Recent foreign travel increased the risk for FQ resistance. Future research efforts should be aimed at better identifying risk factors, targeted prophylaxis and reducing the need for biopsies.

ABSTRACT

Seasonal influenza vaccination is recommended for patients with end-stage renal disease (ESRD), despite suggested inferior efficacy among these patients. We characterize an outbreak of influenza A(H1N1) in a kidney transplant unit. Altogether 23 patients were treated on the ward for postoperative care after kidney transplantation during the outbreak. After the first positive case, all patients were tested with nasopharyngeal swab tests and 7 patients were diagnosed with influenza A(H1N1). Altogether 17/23 patients had received adequate seasonal influenza vaccination, of whom 2/17 tested positive for influenza (one asymptomatic, one with mild cough). Five of six unvaccinated patients were diagnosed with influenza A(H1N1); 3/5 suffered from severe respiratory failure and were treated with ventilator support in the ICU, but all died due to acute respiratory distress syndrome, whereas 2/5 suffered from mild viral pneumonitis and recovered fully. The risk of influenza infection and mortality was significantly increased in unvaccinated patients (odds ratio 37.5 [95% CI 2.7-507.5, p = 0.01] and 6.7 [95% CI 2.3-18.9, p = 0.003], respectively). Influenza A(H1N1) had a high mortality in our cohort of nonvaccinated immunosuppressed patients early after kidney transplantation. None of the vaccinated patients developed serious disease, supporting the role of vaccination also for ESRD patients.

ABSTRACT

BACKGROUND: Clostridium difficile infection (CDI) is the leading cause of infectious nosocomial diarrhoea in Europe. Despite increased focus, its incidence and severity are increasing in many European countries. AIM: We developed a series of consensus statements to identify unmet clinical needs in the recognition and management of CDI. METHODS: A consortium of European experts prepared a series of 29 statements representing their collective views on the diagnosis and management of CDI in Europe. The statements were grouped into the following six broad themes: diagnosis; definitions of severity; treatment failure, recurrence and its consequences; infection prevention and control interventions; education and antimicrobial stewardship; and National CDI clinical guidance and policy. These statements were reviewed using questionnaires by 1047 clinicians involved in managing CDI, who indicated their level of agreement with each statement. FINDINGS: Levels of agreement exceeded the 66% threshold for consensus for 27 out of 29 statements (93.1%), indicating strong support. Variance between countries and specialties was analysed and showed strong alignment with the overall consensus scores. CONCLUSION: Based on the consensus scores of the respondent group, recommendations are suggested for the further development of CDI services in order to reduce transmission and recurrence and to ensure that appropriate diagnosis and treatment strategies are applied across all healthcare settings.

ABSTRACT

INTRODUCTION: Chronic migraine (CM) is at the severe end of the clinical migraine spectrum, but its genetic background is unknown. Our study searched for evidence that genetic factors are involved in the chronification process. METHODS: We initially selected 144 single-nucleotide polymorphisms (SNPs) from 48 candidate genes, which we tested for association in two stages: The first stage encompassed 262 CM patients, the second investigated 226 patients with high-frequency migraine (HFM). Subsequently, SNPs with p values < 0.05 were forwarded to the replication stage containing 531 patients with CM or HFM. RESULTS: Eight SNPs were significantly associated with CM and HFM in the two-stage phase. None survived replication in the third stage. DISCUSSION: We present the first comprehensive genetic association study for migraine chronification. There were no significant findings. Future studies may benefit from larger, genome-wide data sets or should use other genetic approaches to identify genetic factors involved in migraine chronification.

ABSTRACT

The objective of this analysis was to examine the genetic architecture of diverse cognitive abilities in children and adolescents, including the magnitude of common genetic effects and patterns of shared and unique genetic influences. Subjects included 3689 members of the Philadelphia Neurodevelopmental Cohort, a general population sample comprising those aged 8-21 years who completed an extensive battery of cognitive tests. We used genome-wide complex trait analysis to estimate the SNP-based heritability of each domain, as well as the genetic correlation between all domains that showed significant genetic influence. Several of the individual domains suggested strong influence of common genetic variants (for example, reading ability, h(2)g=0.43, P=4e-06; emotion identification, h(2)g=0.36, P=1e-05; verbal memory, h(2)g=0.24, P=0.005). The genetic correlations highlighted trait domains that are candidates for joint interrogation in future genetic studies (for example, language reasoning and spatial reasoning, r(g)=0.72, P=0.007). These results can be used to structure future genetic and neuropsychiatric investigations of diverse cognitive abilities.
