To determine the clinical characteristics of and risk factors for suspected reinfection with coronavirus 2019 (COVID-19). This was a retrospective cohort study using population-based notification records of residents in Kyoto City (1.4 M) with laboratory-confirmed COVID-19 infection between 1 March 2020 and 15 April 2022. Reinfection was defined by two or more positive COVID-19 test results ≧ 90 days apart. Demographic characteristics, the route and timing of infection and history of vaccination were analysed to identify risk factors for reinfection. Among the cohort of 107, 475 patients, reinfection was identified in 0.66% (n = 709). The age group with the highest reinfection rate was 18-39 years (1.06%), followed by 40-59 years (0.58%). Compared to the medical and nursing professionals, individuals who worked in the construction and manufacturing industry (odds ratio [OR]: 2.86; 95% confidence interval [CI]: 1.66-4.92) and hospitality industry (OR: 2.05; 95% CI: 1.28-.31) were more likely to be reinfected. Symptomatic cases at initial infection, receiving more than 2 doses of vaccination and risk factors for severe infection at initial infection were protective factors against reinfection. Of the reinfected individuals, the reinfection route was unknown in 65%. Reinfection with COVID-19 is uncommon, with suspected reinfections more likely in adults, those with high exposure and unvaccinated individuals; the reinfection route was unknown in the majority of cases. This study confirmed the need to continue with self-protection efforts and to implement vaccination programs in high-risk populations.

Background: Comorbid disease may increase mortality in persons with schizophrenia, but how specific diseases are associated with natural and unnatural death in different age groups is unclear. Aims: To investigate the association between eight major comorbid diseases and death from natural and unnatural causes in different age groups in persons with schizophrenia. Method: Retrospective register-based cohort study in 77,794 persons with schizophrenia in Denmark, 1977–2015. Using Cox regression in matched cohorts, we estimated hazard ratios for natural and unnatural death in three age groups (

Purpose Many studies report about risk factors associated with adverse changes in mental health during the COVID-19 pandemic while few studies report about protective and buffering factors, especially in older adults. We present an observational study to assess protective and buffering factors against COVID-19 related adverse mental health changes in older adults. Methods 899 older adults (55 +) in the Netherlands were followed from 2018/19 to two pandemic time points (June–October 2020 and March–August 2021). Questionnaires included exposure to pandemic-related adversities (“COVID-19 exposure”), depressive and anxiety symptoms, loneliness, and pre-pandemic functioning. Linear regression analyses estimated main effects of COVID-19 exposure and protective factors on mental health changes; interaction effects were tested to identify buffering factors. Results Compared to pre-pandemic, anxiety symptoms, depression symptoms and loneliness increased. A higher score on the COVID-19 adversity index was associated with stronger negative mental health changes. Main effects: internet use and high mastery decreased depressive symptoms; a larger network decreased anxiety symptoms; female gender, larger network size and praying decreased loneliness. COVID-19 vaccination buffered against COVID-19 exposure-induced anxiety and loneliness, a partner buffered against COVID-19 exposure induced loneliness. Conclusion Exposure to COVID-19 adversity had a cumulative negative impact on mental health. Improving coping, finding meaning, stimulating existing religious and spiritual resources, network interventions and stimulating internet use may enable older adults to maintain mental health during events with large societal impact, yet these factors appear protective regardless of exposure to specific adversities. COVID-19 vaccination had a positive effect on mental health.

Objectives Urinary incontinence (UI) is highly prevalent peri-partum. To gain more understanding regarding the gap between the prevalence of UI and actual help seeking behaviour of peri-partum women, this study aims to understand, (1) how peri-partum women experience UI and which factors influence these experiences and (2) the perspective of health care professionals on UI during pregnancy, and the first year after childbirth. Methods A qualitative approach was used, using semi-structured interviews with adult pregnant and up to 1 year post-partum women and a focus group with health care professionals (HCP’s) involved in the care of pregnant and post-partum women. Thematic analysis was used to analyse the data. Results Six pregnant and seven post-partum women were included. Nearly all of these women expressed to be not, or only slightly bothered by their UI and accept it as a result of pregnancy and/or delivery. They were surprised because they were unaware that UI could be a problem. None of the HCP’s routinely asked about the presence of UI during pregnancy. At the post-natal check at 6 weeks post-partum, UI is still not a standard question for the majority of the gynecologists and registrars in contrast to the midwives. Conclusions for Practice The interviewed women with UI during pregnancy and the first year after childbirth were surprised but hardly bothered by their UI and accept it as part of being pregnant or as a result of the delivery. HCP’s do not routinely discuss UI during pregnancy or post-partum.

ObjectiveInflammatory bowel disease (IBD) is associated with anxiety and depression, but the magnitude and directionality of risk remains uncertain. This study quantifies the risk of anxiety or depression following a diagnosis of IBD, and the risk of IBD in individuals with anxiety or depression, using population representative data.MethodWe performed a systematic literature search using MEDLINE and Embase and included unselected cohort studies reporting risk of anxiety or depression in patients with IBD or risk of IBD in patients with anxiety or depression. We undertook Random Effect Model meta-analysis to calculate pooled Hazard Ratios (HR) for the risk of anxiety and depression in IBD and subgroup meta-analysis to calculate risk by IBD subtype and in pediatric-onset IBD.ResultsNine studies were included; seven of which examined incidence of anxiety or depression among a total of >150,000 IBD patients. Meta-analysis showed an increased risk of both anxiety (HR: 1.48, 95% CI: 1.29–1.70) and depression (HR: 1.55, 95% CI: 1.35–1.78) following IBD diagnosis. Two studies investigating >400,000 individuals with depression showed a 2-fold increased risk of IBD.ConclusionsThe bidirectional association between IBD and anxiety and depression is clinically relevant and could indicate shared or mutually dependent disease mechanisms.

Background Over the past decades, the therapeutic landscape has markedly changed for patients with metastatic solid cancer, yet few studies have evaluated its effect on population-based survival. The objective of this study was to evaluate the change in survival of patients with de novo metastatic solid cancers during the last 30 years. Methods For this retrospective study, data from almost 2 million patients diagnosed with a solid cancer between January 1, 1989, and December 31, 2018, were obtained from the Netherlands Cancer Registry, with follow-up until January 31, 2021. We classified patients as with or without de novo metastatic disease (M1 or M0, respectively) at diagnosis and determined the proportion with M1 disease over time. Changes in age-standardized net survival were calculated as the difference in the 1- and 5-year survival rates of patients diagnosed in 1989-1993 and 2014-2018. Results Different cancers showed divergent trends in the proportion of M1 disease and increases in net survival for M1 disease (approximately 0-50 percentage points at both 1 and 5 years). Patients with gastrointestinal stromal tumors saw the largest increases in 5-year survival, but we also observed substantial 5-year survival increases for patients with neuroendocrine tumors, melanoma, prostate cancer, and breast cancer. Conclusion Over 30 years, the survival of patients with de novo M1 disease modestly and unevenly increased among cancers. Metastatic cancer still remains a very lethal disease. Next to better treatment options, we call for better preventive measures and early detection to reduce the incidence of metastatic disease.

Background: Implant-based breast reconstructions contribute considerably to the quality of life of breast cancer patients. A knowledge gap exists concerning the potential role of silicone breast implants in the development of so-called “breast implant illness” (BII) and autoimmune diseases in breast cancer survivors with implant-based reconstructions. BII is a constellation of non-specific symptoms reported by a small group of women with silicone breast implants. Methods: The Areola study is a multicenter retrospective cohort study with prospective follow-up aiming to assess the risk of BII and autoimmune diseases in female breast cancer survivors with and without silicone breast implants. In this report, we set out the rationale, study design, and methodology of this cohort study. The cohort consists of breast cancer survivors who received surgical treatment with implant-based reconstruction in six major hospitals across the Netherlands in the period between 2000 and 2015. As a comparison group, a frequency-matched sample of breast cancer survivors without breast implants will be selected. An additional group of women who received breast augmentation surgery in the same years will be selected to compare their characteristics and health outcomes with those of breast cancer patients with implants. All women who are still alive will be invited to complete a web-based questionnaire covering health-related topics. The entire cohort including deceased women will be linked to population-based databases of Statistics Netherlands. These include a registry of hospital diagnostic codes, a medicines prescription registry, and a cause-of-death registry, through which diagnoses of autoimmune diseases will be identified. Outcomes of interest are the prevalence and incidence of BII and autoimmune diseases. In addition, risk factors for the development of BII and autoimmune disorders will be assessed among women with implants. Discussion: The Areola study will contribute to the availability of reliable information on the risks of BII and autoimmune diseases in Dutch breast cancer survivors with silicone breast implants. This will inform breast cancer survivors and aid future breast cancer patients and their treating physicians to make informed decisions about reconstructive strategies after mastectomy. Registration: This study is registered at ClinicalTrials.gov on June 2, 2022 (NCT05400954).

Background: Dietary prevention of cardiovascular risk factors is seldom implemented. Aim: We assessed the dietary changes made by subjects at high risk of cardiovascular disease (CVD). Design and setting: Cross-sectional, multicentre observational study (European Society of Cardiology-ESC EORP-EUROASPIRE V Primary Care) including 78 centres from 16 ESC countries. Methods: Participants aged 18-79 years, devoid of CVD but treated with antihypertensive and/or lipid-lowering and/or antidiabetic therapy were interviewed >6 months and = 60 years, 43.5% with obesity, 71.1% on antihypertensive, 29.2% on lipid-lowering and 31.5% on antidiabetic treatment). Among participants with obesity, 47.7% reported having received dietary advice to lose weight [range: 24.7% (Greece) to 71.8% (Lithuania)]. Among participants on antihypertensive drug therapy, 53.9% reported being on a blood pressure lowering diet [range: 5.6% (UK) to 90.4% (Greece)]; a reduction of salt intake in the last three years was reported by 71.4% [range: 12.5% (Sweden) to 89.7% (Egypt)]. Among participants on lipid-lowering therapy, 56.0% reported being on a lipid lowering diet [range: 7.1% (Sweden) to 90.3% (Egypt)]. Among participants with diabetes, 57.2% reported being on a diet [range: 21.6% (Romania) to 95.1% (Bosnia & Herzegovina)]; a reduction in sugar intake was reported by 80.8% [range: 56.5% (Sweden) to 96.7% (Russian Federation)]. Conclusions: In ESC countries, fewer than 60% of participants at high CVD risk report being on a specific diet, with wide differences between countries. (c) 2023 The Author(s).

Evidence-based intraoperative infection control measures can reduce Staphylococcus aureus transmission and infections. We aimed to determine whether transmitted S. aureus isolates were associated with increased risk of multidrug resistance and associated traits.S. aureus isolates obtained from intraoperative environmental, patient skin, and provider hand reservoirs among 274 operating room case pairs (1Transmitted isolates (N=58) were associated with increased risk of multi-drug antibiotic resistance [33% (19/58) transmitted vs. 10% (12/115) other isolates, risk ratio 3.14, 99% CI 1.34-7.38, P=0.0006]. Transmission was associated with a significant increase in resistance traits including mecA [40% transmitted isolates vs. 17% other isolates, risk ratio 2.28, P=0.0026] and ant (6)-Ia [26% transmitted isolates vs. 9% other isolates, risk ratio 2.97, P=0.0050]. Provider hands were a frequent reservoir of origin, between-case a common mode of transmission, and patient skin and provider hands frequent transmission locations for multidrug resistant pathogens.Intraoperative S. aureus transmission was associated with multidrug resistance and resistance traits. Proven infection control measures should be leveraged to target intraoperative transmission of multidrug resistant pathogens.

Background Studies of period changes in educational inequalities in mortality have shown important changes over time. It is unknown whether a birth cohort perspective paints the same picture. We compared changes in inequalities in mortality between a period and cohort perspective and explored mortality trends among low-educated and high-educated birth cohorts.Data and methods In 14 European countries, we collected and harmonised all-cause and cause-specific mortality data by education for adults aged 30–79 years in the period 1971–2015. Data reordered by birth cohort cover persons born between 1902 and 1976. Using direct standardisation, we calculated comparative mortality figures and resulting absolute and relative inequalities in mortality between low educated and high educated by birth cohort, sex and period.Results Using a period perspective, absolute educational inequalities in mortality were generally stable or declining, and relative inequalities were mostly increasing. Using a cohort perspective, both absolute and relative inequalities increased in recent birth cohorts in several countries, especially among women. Mortality generally decreased across successive birth cohorts among the high educated, driven by mortality decreases from all causes, with the strongest reductions for cardiovascular disease mortality. Among the low educated, mortality stabilised or increased in cohorts born since the 1930s in particular for mortality from cardiovascular diseases, lung cancer, chronic obstructive pulmonary disease and alcohol-related causes.Conclusions Trends in mortality inequalities by birth cohort are less favourable than by calendar period. In many European countries, trends among more recently born generations are worrying. If current trends among younger birth cohorts persist, educational inequalities in mortality may further widen.

External ventricular drain (EVD)-associated infections have a negative impact on healthcare cost and patient outcomes. Practice variation in EVD management may place patients at increased risk for EVD-associated infection. This project aimed to evaluate the impact of implementing an interprofessional evidence-based EVD bundle of care on reduction of EVD-related ventriculitis rates.An interprofessional team developed an evidence based EVD care bundle and order set to eliminate practice inconsistencies. Standardization of EVD equipment and optimization of the electronic health record occurred. Education and competency validation were completed with neurosurgical providers and nurses. Interprofessional rounds occur weekly for observation, recognition, and in-the-moment education.A pre/post intervention design was used to show that the rate of EVD-associated ventriculitis decreased from 8.8 per reported EVD days in 2019 to 0 per reported EVD days in 2021 after implementation of the EVD care bundle.Through an interprofessional team approach, reduction in EVD-associated infection rates is feasible with implementation of an evidence based EVD care bundle.

Some costs for anesthesia supplies to reduce intraoperative infections depend on the procedure and duration of the case. For regular anesthesia supplies and medications, costs are linearly related to American Society of Anesthesiologists' Relative Value Guide units, known for nearly all cases in the United States of America. We hypothesized linear association between costs of infection control items and anesthesia units.A prospective observational study of 38 surgical cases was performed. Usage of anesthesia infection control supplies was recorded: alcohol hand dispensers, microfiber cloths for machine disinfection, and disinfecting and cleaning caps for syringe tips, Luer connectors, and stopcocks. Cost per case was calculated using 2022 US dollar payments for those items.Using least squares linear regression to associate the anesthesia units (base + time) with supply costs, in addition to intercept and linear slope, none of 5 potential extra non-linear terms were significant (all P ≥ .46). Further assessment showed lack of fit to a quadratic model. Pearson linear correlation coefficient between cost and units was 0.88. An example was created showing how to forecast annual infection control supply costs for anesthesia based on the linear model.For purposes of predicting intraoperative anesthesia supplies to reduce bacterial transmission in the anesthesia workspace, a valid approach is to assume a linear association with the total anesthesia units, a predictor generally known for all anesthetics.

Purpose: Recent studies suggest that women are more susceptible to diuretic-induced hyponatremia resulting in hospital admission than men. The aim of this study was to confirm whether these sex differences in hyponatremia-related hospital admissions in diuretic users remain after adjusting for several confounding variables such as age, dose, and concurrent medication. Methods: In a case–control design nested in diuretic users, cases of hyponatremia associated hospital admissions between 2005 and 2017 were identified from the PHARMO Data Network. Cases were 1:10 matched to diuretic users as controls. Odds ratios (OR) with 95%CIs were calculated for women versus men and adjusted for potential confounders (age, number of diuretics, other hyponatremia-inducing drugs, chronic disease score) using unconditional logistic regression analysis. A subgroup analysis was performed for specific diuretic groups (thiazides, loop diuretics and aldosterone antagonists). Results: Women had a statistically significantly higher risk of a hospital admission associated with hyponatremia than men while using diuretics (OR 1.86, 95%CI 1.64–2.11). Adjusting for the potential confounders resulted in an increased risk for women compared to men (ORadj 2.65, 95% CI 2.31–3.04). This higher risk in women was also seen in the three subgroup analyses after adjustment. Conclusion: Our findings show a higher risk of hyponatremia-related hospital admission in women than men while using diuretics. Further research is needed to understand the underlying mechanism of this sex difference to be able to provide sex-specific recommendations.

Residents in nursing facilities (NFs) are at greater risk of developing urinary tract infections (UTIs) with higher hospitalizations and costs than people living in communities. These residents also have increased likelihood of uroseptic shock and death. The objective of the study was to prevent UTIs and to reduce UTI-associated costs among NF residents.Quality assurance performance improvement initiative conducted between April 1, 2018 and March 31, 2022 at a large skilled NF. Participants were 262 residents newly diagnosed with UTIs without indwelling catheters. The initiative consisted of (1) a 12-month baseline; (2) a 12-month intervention; and (3) a 24-month follow-up. A novel care bundle which included staff's hand hygiene monitoring, residents' hydration status, effective incontinence and perineal care, and in-house UTI treatment was implemented during the intervention. The plan-do-study-act cycle was used to gauge its effectiveness.Quarterly UTI rates decreased from 4.2% at baseline to 0.9% at follow-up, a 79% reduction (P.001). All 262 residents were treated in-house with no UTI-related hospitalizations. Antibiotic prescriptions fell from 373 at baseline down to 143 at follow-up, a 62% reduction. Facility costs decreased from $42,188 at baseline to $8,281 at follow-up (P0.001).This bundle was very effective in preventing UTIs and reducing UTI-associated costs. Its use in other NFs is encouraged to determine suitability elsewhere.

SARS-CoV-2 Omicron variant has a high transmission rate. In December 2021, Omicron became the dominant variant and quickly accounted for majority of infections in the United States. Drug shortages have led to prioritization of patients for COVID-19 treatment based on risk factors for severe disease.A retrospective analysis of hospitalized patients with COVID-19 infection at Veteran Affairs Healthcare System across the United States. The primary outcome was 14-day all-cause mortality after the first documented positive SARS-CoV-2 laboratory test. Odds ratios were generated from a multivariate logistic regression of significant factors.This study included 12,936 COVID-19 inpatients during a period of Omicron predominance. Age ≥ 65 years is a predictor of 14-day mortality among the vaccinated and unvaccinated population (OR 4.05, CI 3.06-5.45, P ≤ .0001). Triple vaccinated patients demonstrated a 52% decreased risk of death with COVID-19 infection (OR 0.48, CI 0.37-0.61, P ≤ .0001). Patients who were double vaccinated had a 39% decreased risk of death with COVID-19 infection (OR 0.61, CI 0.46-0.80, P = .003).Advanced age ≥ 65 is the greatest risk factor for mortality in hospitalized COVID-19 patients. COVID-19 vaccination, especially booster doses, was associated with a decreased risk of 14-day mortality compared to double vaccinated or non-vaccinated patients. Results of this study suggest that advanced age should be considered first for prioritization of COVID-19 treatments for Omicron.

Antimicrobial resistance is an emerging global threat that must be addressed using a multidisciplinary approach. This study aimed to raise awareness of high-level antimicrobial-resistant (AMR) pathogens in Japan by comparing their recent prevalences among prefectures, particularly Okayama. Data for the isolation proportions of meropenem-resistant Pseudomonas aeruginosa, methicillin-resistant Staphylococcus aureus, vancomycin-resistant Enterococcus faecium, cefotaxime-resistant Escherichia coli and Klebsiella pneumoniae, and levofloxacin-resistant E. coli and K. pneumoniae were collected from the Japan Nosocomial Infections Surveillance, a national database sponsored by the Japanese Ministry of Health, Labour, and Welfare, between 2018 and 2021. The average isolated proportions of the seven AMR pathogens were higher in Okayama compared to other prefectures: the worst (19.9%) was meropenem-resistant P. aeruginosa, the sixth worst (57.2%) was methicillin-resistant S. aureus, the eighth worst (3.3%) was vancomycin-resistant E. faecium, the second (37.8%) and fifth worst (17.6%) were cefotaxime-resistant E. coli and K. pneumoniae, respectively, and the fourth (49.9%) and third worst (8.7%) were levofloxacin-resistant E. coli and K. pneumoniae, respectively. Our study highlights the notably high prevalences of representative AMR pathogens in Okayama, suggesting the need for fundamental infection prevention and control by healthcare professionals, promoting antimicrobial stewardship, and educating undergraduates and postgraduates in Okayama.

Dietary patterns in childhood have been associated with child neurodevelopment and cognitive performance, while the underlying neurobiological pathway is unclear. We aimed to examine associations of dietary patterns in infancy and mid-childhood with pre-adolescent brain morphology, and whether diet-related differences in brain morphology mediate the relation with cognition. We included 1888 and 2326 children with dietary data at age one or eight years, respectively, and structural neuroimaging at age 10 years in the Generation R Study. Measures of brain morphology were obtained using magnetic resonance imaging. Dietary intake was assessed using food-frequency questionnaires, from which we derived diet quality scores based on dietary guidelines and dietary patterns using principal component analyses. Full scale IQ was estimated using the Wechsler Intelligence Scale for Children-Fifth Edition at age 13 years. Children with higher adherence to a dietary pattern labeled as ‘Snack, processed foods and sugar’ at age one year had smaller cerebral white matter volume at age 10 (B = -4.3, 95%CI -6.9, -1.7). At age eight years, higher adherence to a ‘Whole grains, soft fats and dairy’ pattern was associated with a larger total brain (B = 8.9, 95%CI 4.5, 13.3), and larger cerebral gray matter volumes at age 10 (B = 5.2, 95%CI 2.9, 7.5). Children with higher diet quality and better adherence to a ‘Whole grains, soft fats and dairy’ dietary pattern at age eight showed greater brain gyrification and larger surface area, clustered primarily in the dorsolateral prefrontal cortex. These observed differences in brain morphology mediated associations between dietary patterns and IQ. In conclusion, dietary patterns in early- and mid-childhood are associated with differences in brain morphology which may explain the relation between dietary patterns and neurodevelopment in children.

Maintenance hemodialysis (HD) patients are at increased risk of bloodstream infections (BSI). We investigated a cluster of Delftia acidovorans infections among patients undergoing HD at an outpatient unit (Facility A).A case was defined as a Facility A HD patient with ≥1 culture positive for D acidovorans between February 1 and April 30, 2018. An investigation included review of patient records, facility policies, practice observations, and environmental cultures.The cluster included 2 patients with confirmed D acidovorans BSI. Both patients had recently been dialyzed at Station #2, where a wall box culture yielded D acidovorans. One patient also had a BSI due to Enterobacter asburiae, which was recovered from several other wall boxes and saline prime buckets (SPB). Observations revealed leakage of wastewater from wall boxes onto the floor, and that SPBs were not always disinfected and dried appropriately before reuse. Multiple deficiencies in hand hygiene and station disinfection were observed. No deficiencies in water treatment practices were identified, and water cultures were negative for the observed pathogens.The cluster of D acidovorans infections was most likely due to indirect exposures to contaminated wall boxes and possibly SPBs due to poor hand hygiene and station disinfection.
