Objective Nonmelanoma skin cancer (NMSC) is one of the most diagnosed cancers in the world, with the number of new occurrences rising every year. Most patients with facial skin cancer experience cancer-related worry. Yet, little is known about their worry during the period after cancer treatment. This study aimed to assess the long-term change of cancer worry after surgical treatment in patients with NMSC. Methods Patients undergoing surgery for facial NMSC between December 2017 and March 2020 were asked to complete the FACE-Q Skin Cancer-Cancer Worry scale before (baseline), 3-month, and 1-year post-surgery. Results A total of 151 patients completed the baseline and 3-month, and 99 (65.6%) the 1-year post-operative survey. A significant decrease in cancer worry score was seen between baseline and 3-month post-surgery (p < 0.001). No difference was found between the 3-month and 1-year post-surgery scores (p = 0.78). Less improvement in cancer worry was seen for patients who had one facial skin cancer in their medical history (p = 0.001) and patients who had a history of facial surgery (p < 0.001). Conclusion Post-surgery patients still experience cancer worry. Therefore, targeted counseling might be of value when coping with cancer-related concerns. Patients with a history of facial NMSC and patients with a history of facial surgery might benefit from additional counseling.

BACKGROUND CONTEXT: Lumbar interbody fusion is an effective treatment for unstable spinal segments. However, the time needed to establish a solid bony interbody fusion between the two vertebrae may be longer than twelve months after surgery. During this time window, the instrumented spinal segment is assumed to be at increased risk for instability related complications such as cage migration or subsidence. It is hypothesized that the design of new interbody cages that enable direct osseointegration of the cage at the vertebral endplates, without requiring full bony fusion between the two vertebral endplates, might shorten the time window that the instrumented spinal segment is susceptible to failure.PURPOSE: To quantify the bone ingrowth and resulting segmental stability during consolidation of lumbar interbody fusion using two different cage types.STUDY DESIGN: Preclinical ovine model.METHODS: Seven skeletally mature sheep underwent bi-segmental lumbar interbody fusion surgery with one conventional polyether ether ketone (PEEK) cage, and one newly developed trussed titanium (TT) cage. After a postoperative time period of 13 weeks, non-destructive range of motion testing and histological analysis were performed. Additionally, sample specific finite element (FE) analysis was performed to predict the stability of the interbody fusion region alone.RESULTS: Physiological movement of complete spinal motion segments did not reveal significant differences between the segments operated with PEEK and TT cages. The onset of creeping substitution within the cage seemed to be sooner for PEEK cages, which led to significantly higher bone volume over total volume (BV/TV) compared to the TT cages. TT cages showed significantly more direct bone to implant contact (BIC). Although the mean stability of the interbody fusion region alone was not statistically different between the PEEK and TT cages, the variation within the cage types illustrated an all-or-nothing response for the PEEK cages while a more gradual increase in stability was found for the TT cages.CONCLUSIONS: Spinal segments operated with conventional PEEK cages were not different from those operated with newly developed TT cages in terms of segmental stability but did show a different mechanism of bone ingrowth and attachment. Based on the differences in development of bony fusion, we hypothesize that TT cages might facilitate increased early segmental stability by direct osseointegration of the cage at the vertebral endplates without requiring complete bony bridging through the cage.CLINICAL SIGNIFICANCE: Interbody cage type affects the consolidation process of spinal interbody fusion. Whether different consolidation processes of spinal interbody fusion result in clinically significant differences requires further investigation.

Supplemental digital content is available in the text., Objective In this systematic review, we evaluate 2 of the most used trigger tools according to the criteria of the World Health Organization for evaluating methods. Methods We searched Embase, PubMed, and Cochrane databases for studies (2000–2017). Studies were included if medical record review (MRR) was performed with either the Global Trigger Tool or the Harvard Medical Practice Study in a hospital population. Quality assessment was performed in duplicate. Fifty studies were included, and results were reported for every criterion separately. Results Medical record review reveals more adverse events (AEs) than any other method. However, at the same time, it detects different AEs. The costs of an AE were on average €4296. Considerable efforts have been made worldwide in health care to improve safety and to reduce errors. These have resulted in some positive effects. The literature showed that MRR is focused on several domains of quality of care and seems suitable for both small and large cohorts. Furthermore, we found a moderate to substantial agreement for the presence of a trigger and a moderate to good agreement for the presence of an AE. Conclusions Medical record review with a trigger tool is a reasonably well-researched method for the evaluation of the medical records for AEs. However, looking at the World Health Organization criteria, much research is still lacking or of moderate quality. Especially for the cost of detecting AEs, valuable information is missing. Moreover, knowledge of how MRR changes quality and safety of care should be evaluated.

PURPOSE OF REVIEW To review the recent literature on the epidemiology of anorexia nervosa and bulimia nervosa in terms of incidence, prevalence and mortality. RECENT FINDINGS Although the overall incidence rate of anorexia nervosa is considerably stable over the past decades, the incidence among younger persons (aged

Background and purpose — Periprosthetic joint infection (PJI) is a devastating complication and more information on risk factors for PJI is required to find measures to prevent infections. Therefore, we assessed risk factors for PJI after primary total hip arthroplasty (THA) in a large patient cohort. Patients and methods — We analyzed 33,337 primary THAs performed between May 2014 and January 2018 based on the Finnish Arthroplasty Register (FAR). Cox proportional hazards regression was used to estimate hazard ratios with 95% confidence intervals (CI) for first PJI revision operation using 25 potential patient- and surgical-related risk factors as covariates. Results — 350 primary THAs were revised for the first time due to PJI during the study period. The hazard ratios for PJI revision in multivariable analysis were 2.0 (CI 1.3–3.2) for ASA class II and 3.2 (2.0–5.1) for ASA class III–IV compared with ASA class I, 1.4 (1.1–1.7) for bleeding > 500 mL compared with < 500 mL, 0.4 (0.2–0.7) for ceramic-on-ceramic bearing couple compared with metal-on-polyethylene and for the first 3 postoperative weeks, 3.0 (1.6–5.6) for operation time of > 120 minutes compared with 45–59 minutes, and 2.6 (1.4–4.9) for simultaneous bilateral operation. In the univariable analysis, hazard ratios for PJI revision were 2.3 (1.7–3.3) for BMI of 31–35 and 5.0 (3.5–7.1) for BMI of > 35 compared with patients with BMI of 21–25. Interpretation — We found several modifiable risk factors associated with increased PJI revision risk after THA to which special attention should be paid preoperatively. In particular, high BMI may be an even more prominent risk factor for PJI than previously assessed. publishedVersion

PURPOSE: The Kyleena® Satisfaction Study (KYSS) aimed to assess satisfaction and continuation with levonorgestrel-releasing intrauterine system (LNG-IUS) 12 (Kyleena®) in routine clinical practice and to evaluate factors that influence satisfaction. MATERIALS AND METHODS: This prospective, observational, multicentre, single-arm cohort study, with 1-year follow-up, was conducted in Belgium, Canada, Germany, Mexico, Norway, Sweden, Spain and the United States from 2017 to 2018. During routine counselling, women who independently selected to use LNG-IUS 12 were invited to participate in the study. KYSS assessed LNG-IUS 12 satisfaction, continuation and safety. RESULTS: Overall, there were 1126 successful LNG-IUS 12 placements, with insertion attempted in 1129 women. Most participants (833/968, 86.1%, 95% CI 83.7-88.2%, with satisfaction outcome data available) reported satisfaction with LNG-IUS 12 at 12 months (or at the final visit if the device was discontinued prematurely). Satisfaction was not associated with age, parity or motivation for choosing LNG-IUS 12. The majority of women (919/1129, 81.4%) chose to continue after 12 months. Discontinuation was not correlated with age or parity. Overall, 191 women (16.9%) reported a treatment-emergent adverse event. CONCLUSIONS: Results from KYSS provide the first real-world evidence assessing LNG-IUS 12, and demonstrate high satisfaction and continuation rates irrespective of age or parity.

Objectives: To evaluate the incidence of numerical chromosomal abnormalities in the patients with early pregnancy loss (EPL) following in vitro fertilization, and evaluate the role of different confounders of the risk of chromosomal abnormality-related pregnancy loss. Material and methods: A retrospective chart review of all patients from our in vitro fertilization (IVF) center who conceived using assisted reproduction techniques between April 2017 and 2019, who experienced a subsequent early pregnancy loss, and whose abortus materials were successfully karyotyped were included. Results: Of the 243 patients experienced an early loss, the overall rate of chromosomal abnormality was 46.75%. The overall rate of aneuploidy in our patient group was 88.8% (64/72), whereas 6.94% (5/72) of the abnormal karyotypes were polyploid. The most common type of trisomy was Trisomy 16 (20.0%; 11/55) followed by Trisomy 15 (14.5%; 8/55). Univariate and multivariate analyses showed that maternal age (< 35 years) and the total number of retrieved oocytes per cycle (≥ 5) were risk factors for a chromosomal abnormality (< 0.001; < 0.05, respectively). The adjusted OR of karyotypic abnormalities was 0.45 for the antagonist cycle type (p < 0.05), and 0.58 for frozen embryo transfer (p < 0.05). Conclusions: Karyotypic abnormality is one of the main reasons for pregnancy loss following an IVF procedure. Although the pregnancy rates increased as a result of novel technologies, the ratio of EPL is still high. The implementation of preimplantation genetic screening techniques might lower the incidence of EPL due to chromosomal abnormalities, thus decreasing the burden on the physicians and the patients.

The aim of this nationwide population-based case–control study was to assess the incidence of inguinal hernia (IH) among patients with congenital abdominal wall defects. All infants born with congenital abdominal wall defects between Jan 1, 1998, and Dec 31, 2014, were identified in the Finnish Register of Congenital Malformations. Six controls matched for gestational age, sex, and year of birth were selected for each case in the Medical Birth Register. The Finnish Hospital Discharge Register was searched for relevant diagnosis codes for IH, and hernia incidence was compared between cases and controls. We identified 178 infants with gastroschisis and 150 with omphalocele and selected randomly 1968 matched, healthy controls for comparison. Incidence of IH was significantly higher in gastroschisis girls than in matched controls, relative risk (RR) 7.20 (95% confidence interval [CI] 2.25–23.07). In boys with gastroschisis, no statistically significant difference was observed, RR 1.60 (95% CI 0.75–3.38). Omphalocele was associated with higher risk of IH compared to matched controls, RR 6.46 (95% CI 3.90–10.71), and the risk was equally elevated in male and female patients.Conclusion: Risk of IH is significantly higher among patients with congenital abdominal wall defects than in healthy controls supporting hypothesis that elevated intra-abdominal pressure could prevent natural closure of processus vaginalis. Parents should be informed of this elevated hernia risk to avoid delays in seeking care. We also recommend careful follow-up during the first months of life as most of these hernias are diagnosed early in life.What is Known:• Inguinal hernia is one of the most common disorders encountered by a pediatric surgeon.• Prematurity increases the risk of inguinal hernia.What is New:• Children with congenital abdominal wall defects have a significantly higher risk of inguinal hernia than general population.• Families should be informed of this elevated hernia risk to avoid delays in seeking care.

Background There are few data comparing the relative effectiveness of the individual β-lactams. Objectives To quantify the reduced effectiveness, defined as switching to a different antibiotic being prescribed for the same indication, among new users of β-lactam antibiotics in primary care. Methods A retrospective cohort study was conducted using the Health Search Database, an Italian primary care data source. Patients newly prescribed with β-lactams for a specific indication between 1 January 2013 and 31 December 2017 were identified. A switch to a different antibiotic for the same indication occurring during a 30day follow-up was the study outcome. Cox regression was adopted to assess the risk of switching between the different β-lactams. Results Among 178 256 patients newly treated with β-lactam antibiotics, 1172 (0.65%) switched to a different antibiotic. Amoxicillin/clavulanate (co-amoxiclav: n = 104 891) and amoxicillin (n = 21 699) were the most frequently prescribed β-lactams. The other antibiotics showed significantly higher risk of switching when compared with co-amoxiclav for lower respiratory tract [e.g. ceftriaxone, hazard ratio (HR): 1.6, 95% CI: 1.2–2.0], dental [e.g. amoxicillin, HR: 4.2, 95% CI: 2.9–5.9], and middle ear infections [e.g. amoxicillin, HR: 1.8, 95% CI: 1.1–2.7]. The same results were gathered when parenteral formulations were excluded. Conclusions The prevalence of reduced effectiveness of newly prescribed β-lactam antibiotics was lower than 1%. Specifically, the rate of switch to another antibiotic, when it was prescribed to treat low respiratory tract, dental, and middle ear infections, was lower among users of co-amoxiclav than those prescribed with other β-lactams.

Background Depressive and anxiety disorders are often associated with suicide ideation (SI) and attempt (SA). However, analyses of prevalence, course, and more specific risk mechanisms are needed to improve knowledge and detection of high risk individuals with depressive and anxiety disorders. Previous studies often lacked statistical power, assessment of detailed determinants and follow-up measurements. Methods The Netherlands Study of Depression and Anxiety (NESDA), a large cohort study, overcomes some earlier limitations. Scale for Suicide Ideation and Compositive Interview Diagnostic Instrument data were analyzed to report on prevalence of SI and SA. Additionally, important sociodemographic, clinical, psychological, environmental, and neurobiological determinants and course of SI and SA identified in depressive and/or anxiety disorder respondents in 16 NESDA articles were summarized. Results Within respondents with 12-month diagnosis (n=1,783), SI and 12-month SA prevalence ranged from 17.1-20.1% and 0.8-3.0% respectively across 5 waves during 9-year follow-up and SI was highly recurrent. Both SI and SA were especially associated with comorbid depression and anxiety, higher clinical severity, sleep dysfunctions, higher aggression and hopelessness, and childhood trauma. In the (neuro)biological domain, SI was linked with immune dysregulation and SA with abnormal brain activity during emotion processing and genetic risk. Limitations Most articles were cross-sectional in nature, preventing causal inferences and no conclusions could be drawn about the overall magnitude of results. Conclusion SI and SA are multifactorial phenomena and especially prevalent amongst comorbid depressive and anxiety respondents. Considering many overlapping SI and SA determinants, more neurobiological determinants and use of innovative methodological techniques are desirable.

OBJECTIVEComplications after adult spinal deformity surgery are common, with implant-related complications occurring in up to 27.8% of cases. Sublaminar wire fixation strength is less affected by decreasing trabecular bone density in comparison to pedicle screw (PS) fixation due to the predominant cortical bone composition of the lamina. Sublaminar fixation may thus aid in decreasing implant-related complications. The goal of this study was to compare fixation characteristics of titanium sublaminar cables (SCs), ultra–high-molecular-weight polyethylene (UHMWPE) tape, PSs, and PSs augmented with UHMWPE tape in an ex vivo flexion–bending setup.METHODSThirty-six human cadaver vertebrae were stratified into 4 different fixation groups: UHMWPE sublaminar tape (ST), PS, metal SC, and PS augmented with ST (PS + ST). Individual vertebrae were embedded in resin, and a flexion–bending moment was applied that closely resembles the in vivo loading pattern at transitional levels of spinal instrumentation.RESULTSThe failure strength of PS + ST (4522 ± 2314 N) was significantly higher compared to the SC (2931 ± 751 N) and PS (2678 ± 827 N) groups, which had p values of 0.028 and 0.015, respectively (all values expressed as the mean ± SD). Construct stiffness was significantly higher for the PS groups compared to the stand-alone sublaminar wiring groups (p = 0.020). In contrast to SC, ST did not show any case of cortical breach.CONCLUSIONSThe higher failure strength of PS + ST compared to PS indicates that PS augmentation with ST may be an effective measure to reduce the incidence of screw pullout, even in osteoporotic vertebrae. Moreover, the lower stiffness of sublaminar fixation techniques and the absence of damage to the cortices in the ST group suggest that ST as a stand-alone fixation technique in adult spinal deformity surgery may also be clinically feasible and offer clinical benefits.

Background: To evaluate whether patients of varying ages and lung function with asthma or those with chronic obstructive pulmonary disease (COPD) can achieve sufficient inspiratory flows for effective use of the fixed-dose combination of salmeterol-fluticasone propionate and budesonide-formoterol dispensed with the Easyhaler (R) (EH) device-metered, multi-dose dry powder inhaler (DPI). Methods: A pooled analysis of two randomized, multicenter, crossover, open-label studies (NCT01424137; NCT009849061) was conducted to characterize inspiratory flow parameters across the EH, Seretide Diskus (DI) and Symbicort Turbuhaler (TH) inhalers in patients with asthma and/or COPD of varying severity. The primary endpoint was peak inspiratory flow (PIF) rate through the EH. Results: The intent-to-treat population comprised 397 patients; 383 patients were included in the per protocol (PP) population. The mean PIF (standard deviation) values through the EH in patients = 18 years of age with asthma and in those with COPD, were similar: 61.4 (11.5), 69.7 (13.5), and 61.9 (13.2) L/min, respectively. These flow rates correspond to pressure drops of 5.05 (1.80), 6.52 (2.34) and 5.19 (2.07) kPa, respectively. In total, 380 (99.2%) of patients in the PP population were able to generate a PIF rate through the EH of >= 30 L/min, which is required to enable consistent dose delivery from the DPI; there was a moderate direct association between age and PIF in younger patients with asthma, but this was inverse and less apparent in adult patients with asthma and/or those with COPD. Height and weight were also moderately correlated with PIF. Stronger associations with PIF were observed for some lung function parameters, particularly native PIF and forced inspiratory vital capacity. Conclusions: Over 99% of patients with asthma and/or COPD were able to inhale through the EH with an adequate PIF rate, irrespective of age, or severity of airway obstruction. This confirms that patients with asthma and/or COPD can achieve inspiratory flows via the EH DPI that are sufficient for its effective use.

Objectives Regulators of circadian rhythm, including melatonin, influence fundamental biological processes. Measuring the melatonin metabolite 6-sulfatoxymelatonin in urine can estimate melatonin production. 6-sulfatoxymelatonin is mainly analyzed by immunoassays, but these methods are hampered by cross-reactivity and poor reproducibility when used to analyze small molecules. Therefore, we validated a high-throughput liquid chromatography with tandem mass spectrometry (LC–MS/MS) method to quantify 6-sulfatoxymelatonin in urine. We evaluated age-dependent 24-h excretion of 6-sulfatoxymelatonin into urine and the biological variation of urinary excretion in healthy individuals. Methods The online solid phase extraction method combined with LC–MS/MS was validated according to international guidelines, and used to measure the excretion of 6-sulfatoxymelatonin into urine of 240 healthy individuals. Biological variation of 6-sulfatoxymelatonin excretion was examined in 10 healthy individuals. Results Urinary 6-sulfatoxymelatonin results were well within the validation criteria (interassay coefficient of variation: Conclusions This MS-based method enables straightforward, reproducible, and sensitive quantification of 6-sulfatoxymelatonin in urine. Urinary 6-sulfatoxymelatonin levels decreased with age. Biological variation of 6-sulfatoxymelatonin excretion into urine was high between subjects and lower within subjects, indicating that repeated measurements of 6-sulfatoxymelatonin in 24-h urine are needed in future studies.

BackgroundTreatment-resistant schizophrenia (TRS) is associated with high levels of functional impairment, healthcare usage and societal costs. Cross-sectional studies may overestimate TRS rates because of selection bias.AimsWe aimed to quantify TRS rates by using first-episode cohorts to improve resource allocation and clozapine access.MethodWe undertook a systematic review of TRS rates among people with first-episode psychosis and schizophrenia, with a minimum follow-up of 8 weeks. We searched PubMed, PsycINFO, EMBASE, CINAHL and the Cochrane Database of Systematic Reviews, and meta-analysed TRS rates from included studies.ResultsTwelve studies were included, totalling 11 958 participants; six studies were of high quality. The rate of TRS was 22.8% (95% CI 19.1–27.0%, P < 0.001) among all first-episode cohorts and 24.4% (95% CI 19.5–30.0%, P < 0.001) among first-episode schizophrenia cohorts. Subgroup sensitivity analyses by location of recruitment, TRS definition, study quality, time of data collection and retrospective versus prospective data collection did not lead to statistically significant differences in heterogeneity. In a meta-regression, duration of follow-up and percentage drop-out did not significantly affect the overall TRS rate. Men were 1.57 times more likely to develop TRS than women (95% CI 1.11–2.21, P = 0.010).ConclusionsAlmost a quarter of people with first-episode psychosis or schizophrenia will develop TRS in the early stages of treatment. When including people with schizophrenia who relapse despite initial response and continuous treatment, rates of TRS may be as high as a third. These high rates of TRS highlight the need for improved access to clozapine and psychosocial supports.

Objective: The study was aimed to elucidate risk factors identifiable from ward-derived data of thirty-day re-hospitalization among patients undergoing total hip and total knee arthroplasty. Methods: The study was designed as a cross-sectional and prospective study. The data of the study were collected through the Patient Sociodemographic Form, the Nurse Physical Assessment and Observation Form, the Charlson Comorbidity Index (CCI), and the Katz Activities of Daily Living (ADL) Scale. Results: Patients were scored using this CCI system and grouped as high (high CCI group >2, n = 49) and low CCI (low CCI group ≤2, n = 78) with a cut-off score of 2. The 30-day re-hospitalization rate was 14.2%, and the most common reason for re-hospitalization was a surgical infection. Surgical risk, Activities of daily living dependency, and comorbidities index scores of the patients were not significantly additive effects on rehospitalization (p> 0.05). The results indicate that surgical infection was often the cause of higher rates of re-hospitalization among patients with total knee and total hip arthroplasty. Conclusions: Conclusions: Orthopedic nurses should close observation of surgical site infection and design an effective discharge following-up order to the prevention of re-hospitalization in patients with“high risk”.

Background: Although some studies have reported a decrease in preterm birth following the start of the COVID-19 pandemic, the findings are inconsistent. Objective: This study aimed to compare the incidences of preterm birth before and after the introduction of COVID-19 mitigation measures in Scandinavian countries using robust population-based registry data. Study Design: This was a registry-based difference-in-differences study using births from January 2014 through December 2020 in Norway, Sweden, and Denmark. The changes in the preterm birth (

Summary In Austria, data on vaccine hesitancy is scarce. Available studies suggest around 1-11% of parents refuse vaccination, while many more are hesitant and consider refraining from some but not all of the recommended vaccinations. However, the key drivers for vaccine hesitancy in Austria are largely unknown. To learn more about vaccination coverage, attitude towards and knowledge around immunization as well as views on mandatory vaccination, we conducted a survey in a rural Austrian lay population including adults and children. Two paper-based questionnaires, one for adults 16 years or older and one for children aged 6-15 years, were developed, then sent to all houses of a rural community in Austria as well as handed out at the local primary and middle school, respectively. Self-reported coverage rates of children and adults were found to be low. Within the surveyed population 3% of children had never been or do not get vaccinated. More than half (57%) of the survey participants had a positive attitude towards vaccines, 21% were without reserves, 16% were found skeptical and 5% had a generally negative attitude. Knowledge about immunization in general was poor. Younger adults and people with secondary education appear to be most skeptical and negative towards vaccination. Children’s attitudes were closely linked to those of their parents. The major concern around vaccination in adults was fear of side effects. In adults, 54.2% support mandatory vaccination for Health Care Workers and 20.7% are against it. 39% of adults and 37% of children wanted more information on vaccination, preferably provided by physicians. Knowledge about disease prevention by vaccination should be improved and children could also benefit from an early age-appropriate vaccine education to strengthen health literacy. Physicians are the most trusted source of health information. Medical doctors should be aware of their very important role in transmitting trusted health information. This should include an up-to-date education in communicable disease prevention and immunization during their whole medical career. Furthermore, the curricula of health-care workers may need to be improved and harmonized concerning prevention and vaccination.

Aims Unicompartmental knee arthroplasty (UKA) and bicompartmental knee arthroplasty (BCA) have been associated with improved functional outcomes compared to total knee arthroplasty (TKA) in suitable patients, although the reason is poorly understood. The aim of this study was to measure how the different arthroplasties affect knee extensor function. Methods Extensor function was measured for 16 cadaveric knees and then retested following the different arthroplasties. Eight knees underwent medial UKA then BCA, then posterior-cruciate retaining TKA, and eight underwent the lateral equivalents then TKA. Extensor efficiency was calculated for ranges of knee flexion associated with common activities of daily living. Data were analyzed with repeated measures analysis of variance (α = 0.05). Results Compared to native, there were no reductions in either extension moment or efficiency following UKA. Conversion to BCA resulted in a small decrease in extension moment between 70° and 90° flexion (p < 0.05), but when examined in the context of daily activity ranges of flexion, extensor efficiency was largely unaffected. Following TKA, large decreases in extension moment were measured at low knee flexion angles (p < 0.05), resulting in 12% to 43% reductions in extensor efficiency for the daily activity ranges. Conclusion This cadaveric study found that TKA resulted in inferior extensor function compared to UKA and BCA. This may, in part, help explain the reported differences in function and satisfaction differences between partial and total knee arthroplasty. Cite this article: Bone Joint Res 2021;10(1):1–9.

A previous chlamydia infection did not result in fewer pregnant women, but among women with a pregnancy intention, time to pregnancy was longer compared with women without a previous infection. Supplemental digital content is available in the text., Background A Chlamydia trachomatis infection (chlamydia) can result in tubal factor infertility in women. To assess if this association results in fewer pregnant women, we aimed to assess pregnancy incidences and time to pregnancy among women with a previous chlamydia infection compared with women without one and who were participating in the Netherlands Chlamydia Cohort Study (NECCST). Methods The NECCST is a cohort of women of reproductive age tested for chlamydia in a chlamydia screening trial between 2008 and 2011 and reinvited for NECCST in 2015 to 2016. Chlamydia status (positive/negative) was defined using chlamydia screening trial–nucleic acid amplification test results, chlamydia immunoglobulin G presence in serum, or self-reported chlamydia infections. Data on pregnancies were collected via questionnaires in 2015–2016 and 2017–2018. Overall pregnancies (i.e., planned and unplanned) and time to pregnancy (among women with a pregnancy intention) were compared between chlamydia-positive and chlamydia-negative women using Cox regressions. Results Of 5704 women enrolled, 1717 (30.1%; 95% confidence interval [CI], 28.9–31.3) women was chlamydia positive. Overall pregnancy proportions were similar in chlamydia-positive and chlamydia-negative women (49.0% [95% CI, 46.5–51.4] versus 50.5% [95% CI, 48.9–52.0]). Pregnancies per 1000 person-years were 53.2 (95% CI, 51.5–55.0) for chlamydia negatives and 83.0 (95% CI, 78.5–87.9) for chlamydia positives. Among women with a pregnancy intention, 12% of chlamydia-positive women had a time to pregnancy of >12 months compared with 8% of chlamydia negatives (P < 0.01). Conclusions Overall pregnancy rates were not lower in chlamydia-positive women compared with chlamydia-negative women, but among women with a pregnancy intention, time to pregnancy was longer and pregnancy rates were lower in chlamydia-positive women.

Contains fulltext : 229468.pdf (Publisher’s version ) (Closed access) BACKGROUND: Patients diagnosed with sarcoma are hypothesized to experience a prolonged route to a cancer diagnosis. This route, the total interval, can be divided into a patient interval (the time from the appearance of symptoms to physician consultation) and diagnostic interval (time from the first consultation to diagnosis). In the current study, the authors investigated these intervals among survivors of sarcoma and identified factors associated with prolonged intervals. METHODS: A cross-sectional study was conducted among adult patients with sarcoma 2 to 10 years after diagnosis. Patients completed a questionnaire regarding their total interval, which was linked to clinical data from the Netherlands Cancer Registry. Descriptive statistics were used to describe intervals. Based on Dutch clinical guidelines, a diagnostic interval ≥1 month was considered to be prolonged and an interval ≥3 months was considered as very long. Multivariable regression analyses investigated associations between patient and tumor characteristics and interval length. RESULTS: A total of 1099 participants were included (response rate, 58%); approximately 60% reported a patient interval ≥1 month and 36% reported a patient interval ≥3 months. Risk factors for a very long patient interval were sarcoma of the skin or pelvis, liposarcoma, or rhabdomyosarcoma. Stage III disease was associated with a shorter patient interval. The diagnostic interval length was ≥1 month in 55% of patients and ≥3 months in 28% of patients. Risk factors for a very long diagnostic interval were female sex, age

One of the main objectives of the European health policy framework is to ensure equitable access to high-quality health services across Europe. Here we examined country-specific kidney transplantation and graft failure rates in children and explore their country- and patient-level determinants. Patients under 20 years of age initiating kidney replacement therapy from January 2007 through December 2015 in 37 European countries participating in the ESPN/ERA-EDTA Registry were included in the analyses. Countries were categorized as low-, middle-, and high-income based on gross domestic product. At five-years of follow-up, 4326 of 6909 children on kidney replacement therapy received their first kidney transplant. Overall median time from kidney replacement therapy start to first kidney transplantation was 1.4 (inter quartile range 0.3-4.3) years. The five-year kidney transplantation probability was 48.8% (95% confidence interval: 45.9-51.7%) in low-income, 76.3% (72.8-79.5%) in middle-income and 92.3% (91.0-93.4%) in high-income countries and was strongly associated with macro-economic factors. Gross domestic product alone explained 66% of the international variation in transplantation rates. Compared with high-income countries, kidney transplantation was 76% less likely to be performed in low-income and 58% less likely in middle-income countries. Overall five-year graft survival in Europe was 88% and showed little variation across countries. Thus, despite large disparities transplantation access across Europe, graft failure rates were relatively similar. Hence, graft survival in low-risk transplant recipients from lower-income countries seems as good as graft survival among all (low, medium, and high risk) graft recipients from high-income countries.

Clinicians tend to overestimate their ability to recognize feigning behavior in psychiatric patients, especially if it concerns patients who have been admitted for observation. Feigning can be either externally motivated (e.g., for financial compensation, known as malingering) or internally motivated (e.g., to assume the "sick role," known as factitious disorder). Persistent presentation of severe symptoms is usually associated with the factitious disorder. We present two patients with strong external incentives who consistently and convincingly feigned severe psychiatric symptoms during a protracted period of inpatient observation in a specialized center; both were engaged in a procedure for medical asylum. The first case presented with the clinical picture of a psychotic depression with severe motor symptoms, and the second case showed symptoms of a chronic post-traumatic stress disorder with secondary psychotic symptoms. Both cases were thoroughly investigated but feigning was overlooked, and unnecessary and harmful treatment interventions were given. To prevent iatrogenic damage, we recommend a critical attitude that takes malingering as an option into account in settings where patients are often involved in high stake legal procedures. A clinical sign that might indicate feigning is therapy-resistant symptoms. To rule out feigning a comprehensive, multimethod approach is required, but an active stance toward collateral information is essential. Specialized psychological tests may be useful for preliminary screening, but for their use in culturally diverse populations as in refugee mental health more research is needed.

Purpose To compare the long-term clinical results and complications of two revision strategies for patients with failed total disc replacements (TDRs). Methods In 19 patients, the TDR was removed and the intervertebral defect was filled with a femoral head bone strut graft. In addition, instrumented posterolateral fusion was performed (removal group). In 36 patients, only a posterolateral instrumented fusion was performed (fusion group). Visual analogue scale (VAS) for pain and Oswestry Disability Index (ODI) were completed pre- and post-revision surgery. Intra- and post-operative complications of both revision strategies were assessed. Results The median follow-up was 12.3 years (range 5.3–24.3). In both the removal and fusion group, a similar (p = 0.515 and p = 0419, respectively) but significant decrease in VAS- (p = 0.001 and p = 0.001, respectively) and ODI-score (p = 0.033 and p = 0.013, respectively) at post-revision surgery compared to pre-revision surgery was seen. A clinically relevant improvement in VAS- and ODI-score was found in 62.5% and 43.8% in the removal group and in 43.5% and 39.1% in the fusion group (p = 0.242 and p = 0.773, respectively). Removal of the TDR was associated with substantial intra-operative complications such as major vessel bleeding and ureter lesion. The percentage of late reoperations for complications such as pseudarthrosis was comparable for both revision strategies. Conclusions Revision of a failed TDR is clinically beneficial in about half of the patients. No clear benefits for additional TDR removal as compared to posterolateral instrumented fusion alone could be identified. Particularly, when considering the substantial risks and complications, great caution is warranted with removal of the TDR.

Background and Purpose: Cognitive impairment no dementia (CIND) and dementia are common stroke outcomes, with significant health and societal implications for aging populations. These outcomes are not included in current epidemiological models. We aimed to develop an epidemiological model to project incidence and prevalence of stroke, poststroke CIND and dementia, and life expectancy, in Ireland to 2035, informing policy and service planning. Methods: We developed a probabilistic Markov model (the StrokeCog model) applied to the Irish population aged 40 to 89 years to 2035. Data sources included official population and hospital-episode statistics, longitudinal cohort studies, and published estimates. Key assumptions were varied in sensitivity analysis. Results were externally validated against independent sources. The model tracks poststroke progression into health states characterized by no cognitive impairment, CIND, dementia, disability, stroke recurrence, and death. Results: We projected 69 051 people with prevalent stroke in Ireland in 2035 (22.0 per 1000 population [95% CI, 20.8–23.1]), with 25 274 (8.0 per 1000 population [95% CI, 7.1–9.0]) of those projected to have poststroke CIND, and 12 442 having poststroke dementia (4.0 per 1000 population [95% CI, 3.2–4.8]). We projected 8725 annual incident strokes in 2035 (2.8 per 1000 population [95% CI, 2.7–2.9]), with 3832 of these having CIND (1.2 per 1000 population [95% CI, 1.1–1.3]), and 1715 with dementia (0.5 per 1000 population [95% CI, 0.5–0.6]). Life expectancy for stroke survivors at age 50 was 23.4 years (95% CI, 22.3–24.5) for women and 20.7 (95% CI, 19.5–21.9) for men. Conclusions: This novel epidemiological model of stroke, poststroke CIND, and dementia draws on the best available evidence. Sensitivity analysis indicated that findings were robust to assumptions, and where there was uncertainty a conservative approach was taken. The StrokeCog model is a useful tool for service planning and cost-effectiveness analysis and is available for adaptation to other national contexts.

Background: Poststroke cognitive impairment is common, but the trajectory and magnitude of cognitive decline after stroke is unclear. We examined the course and determinants of cognitive change after stroke using individual participant data from the Stroke and Cognition Consortium. Methods: Nine longitudinal hospital-based cohorts from 7 countries were included. Neuropsychological test scores and normative data were used to calculate standardized scores for global cognition and 5 cognitive domains. One-step individual participant data meta-analysis was used to examine the rate of change in cognitive function and risk factors for cognitive decline after stroke. Stroke-free controls were included to examine rate differences. Based on the literature and our own data that showed short-term improvement in cognitive function after stroke, key analyses were restricted to the period beginning 1-year poststroke to focus on its long-term effects. Results: A total of 1488 patients (mean age, 66.3 years; SD, 11.1; 98% ischemic stroke) were followed for a median of 2.68 years (25th–75th percentile: 1.21–4.14 years). After an initial period of improvement through up to 1-year poststroke, decline was seen in global cognition and all domains except executive function after adjusting for age, sex, education, vascular risk factors, and stroke characteristics (−0.053 SD/year [95% CI, −0.073 to −0.033]; P P Conclusions: Patients with stroke experience cognitive decline that is faster than that of stroke-free controls from 1 to 3 years after onset. An increased rate of decline is associated with older age and recurrent stroke.

BACKGROUND: Perinatal mortality in foetuses/children with congenital anomalies remains high. Prenatal diagnosis, essential for risk assessment and organisation of perinatal/postnatal care, offers parents the opportunity to consider the termination of pregnancy. In times of quick changes in prenatal screening programmes, it is relevant to evaluate the effect of prenatal screening on perinatal mortality rates.OBJECTIVES: The objective of this study was to study trends in early foetal and perinatal mortality associated with congenital anomalies before/after the introduction of the Dutch prenatal screening programme.METHODS: This population-based cohort study included 8535 foetuses/neonates with congenital anomalies born in the Northern Netherlands between 2001 and 2017. Total deaths were defined as sum of early foetal (before 24 weeks' gestation) and perinatal deaths (from 24 weeks' gestation till day 7 post-partum). Foetal deaths were categorised into spontaneous or elective termination of pregnancy for foetal anomalies (TOPFA). Trends in total mortality as well as early foetal and perinatal mortality were studied. Joinpoint regression was used to calculate the average annual percentage chance (AAPC) and identify linear trends in mortality within subperiods.RESULTS: Total and perinatal mortality were 17% and 4%. Total mortality was higher in abnormal karyotype and central nervous system anomalies. We observed an increase in total mortality over time: 11.9% in 2001 versus 21.9% in 2017 (AAPC 2.6, 95% confidence interval [CI] 1.5, 3.7), caused by an increase in early foetal mortality from 5.5% to 19.2% (AAPC 8.7, 95% CI 4.7, 12.9) and a decrease in perinatal mortality from 6.4% to 2.7% (AAPC -5.6, 95% CI -10.0, -1.0). The increase in early foetal mortality reflects an increase in TOPFA from 3.6% to 16.9% (AAPC 8.3, 95% CI 4.2, 12.7), mostly occurring at 13-14 and 20-23 weeks' gestation.CONCLUSIONS: The introduction of the prenatal screening programme led to a decrease in perinatal mortality among foetuses and neonates with congenital anomalies and a marked increase in early foetal mortality before 24 weeks' gestation due to higher rates of TOPFA.

Introduction Today, it is widespread practice to postpone frozen embryo transfer (FET) in a modified natural cycle (mNC) for at least one menstrual cycle after oocyte retrieval and failed fresh embryo transfer or freeze-all. The rationale behind this practice is the concern that suboptimal ovarian, endometrial or endocrinological conditions following ovarian stimulation may have a negative impact on endometrial receptivity and implantation. However, two recent systematic reviews and meta-analyses based on retrospective data did not support this practice. As unnecessary delay in time to transfer and pregnancy should be avoided, the aim of this study is to investigate if immediate single blastocyst transfer in mNC-FET is non-inferior to standard postponed single blastocyst transfer in mNC-FET in terms of live birth rate. Methods and analysis Multicentre randomised controlled non-blinded trial including 464 normo-ovulatory women aged 18–40 years undergoing single blastocyst mNC-FET after a failed fresh or freeze-all cycle. Participants are randomised 1:1 to either FET in the first menstrual cycle following the stimulated cycle (immediate FET) or FET in the second or subsequent cycle following the stimulated cycle (postponed FET). The study is designed as a non-inferiority trial and primary analyses will be performed as intention to treat and per protocol. Ethics and dissemination Ethical approval has been granted by the Scientific Ethical Committee of the Capital Region of Denmark (J-nr.: H-19086300). Data will be handled according to Danish law on personal data protection in accordance with the general data protection regulation. Participants will complete written consent forms regarding participation in the study and storage of blood samples in a biobank for future research. The study will be monitored by a Good Clinical Practice (GCP)-trained study nurse not otherwise involved in the study. The results of this study will be disseminated by publication in international peer-reviewed scientific journals. Trial registration number NCT04748874; Pre-results.

Objective:Performance and symptom validity tests (PVTs and SVTs) measure the credibility of the assessment results. Cognitive impairment and apathy potentially interfere with validity test performance and may thus lead to an incorrect (i.e., false-positive) classification of the patient’s scores as non-credible. The study aimed at examining the false-positive rate of three validity tests in patients with cognitive impairment and apathy.Methods:A cross-sectional, comparative study was performed in 56 patients with dementia, 41 patients with mild cognitive impairment, and 41 patients with Parkinson’s disease. Two PVTs – the Test of Memory Malingering (TOMM) and the Dot Counting Test (DCT) – and one SVT – the Structured Inventory of Malingered Symptomatology (SIMS) – were administered. Apathy was measured with the Apathy Evaluation Scale, and severity of cognitive impairment with the Mini Mental State Examination.Results:The failure rate was 13.7% for the TOMM, 23.8% for the DCT, and 12.5% for the SIMS. Of the patients with data on all three tests (n = 105), 13.5% failed one test, 2.9% failed two tests, and none failed all three. Failing the PVTs was associated with cognitive impairment, but not with apathy. Failing the SVT was related to apathy, but not to cognitive impairment.Conclusions:In patients with cognitive impairment or apathy, failing one validity test is not uncommon. Validity tests are differentially sensitive to cognitive impairment and apathy. However, the rule that at least two validity tests should be failed to identify non-credibility seemed to ensure a high percentage of correct classification of credibility.

Aim: Data on the real-world use of hyaluronidase-facilitated subcutaneous 10% immunoglobulin (fSCIG; HyQvia (R)) in elderly patients with primary or secondary immunodeficiencies (PID or SID) are unreported. This study determined real-world patterns from one administration of fSCIG. Materials & methods: In this retrospective, multicenter study, medical records of patients aged >= 65 years with PID or SID were reviewed. Results: The majority of patients (mean age: 69.9 years) with PID (n = 10) or SID (n = 6) self-administered fSCIG (200-350 ml) at home every 3-4 weeks using a single infusion site by infusion pump at rates up to 300 ml/h. Conclusion: This study provides initial real-world evidence supporting home-based, self-administration of large volumes of fSCIG in elderly patients with PID or SID.Lay abstract: Elderly patients may have physical difficulties and medical conditions that could challenge or limit the use of immunoglobulin therapy. Recombinant human hyaluronidase-facilitated subcutaneous 10% immunoglobulin (fSCIG) is a treatment that can reduce infections in people who have immunodeficiencies. fSCIG allows for self-administration of a large quantity of IgG, every 3-4 weeks, in the comfort of the patient's home. We report on 16 elderly patients with impaired immune systems who have received at least one treatment of fSCIG. We found that, similar to younger patients, older patients with impaired immune systems could be safely treated with fSCIG at home.Graphical abstract:[GRAPHICS].

Objective Autopsy rates have been declining worldwide. The present study reports the outcome of a retrospective analysis of all non-forensic autopsies in the Netherlands over a course of 25 years, and compares these with the most recent Dutch study.Method Retrospectively, 25 years of data on clinical autopsies from the Nationwide Network and Registry of Histo- and Cytopathology in the Netherlands (PALGA) was paired with the mortality registry ( Statistics Netherlands).Results The crude prevalence of autopsies declined from 7.07% in 1991 to 2.73% in 2015. After adjusting for age at death, there was no difference in autopsy rate between males and females. An increasing age significantly decreased the autopsy rate.Conclusion In the Netherlands, clinical autopsies have been declining over the last quarter century. Age at death, but not sex, was associated with the autopsy rate. These different results stress the importance of correct collection and analysis methods of data.

Background: Hypospadias is a common male birth defect that has shown widespread variation in reported prevalence estimates. Many countries have reported increasing trends over recent decades.Objective: To analyze the prevalence and trends of hypospadias for 27 international programs over a 31-yr period.Design, setting, and participants: The study population included live births, stillbirths, and elective terminations of pregnancy diagnosed with hypospadias during 1980-2010 from 27 surveillance programs around the world.Outcome measurements and statistical analysis: We used joinpoint regression to analyze changes over time in international total prevalence of hypospadias across programs, prevalence for each specific program, and prevalence across different degrees of severity of hypospadias.Results and limitations: The international total prevalence of hypospadias for all years was 20.9 (95% confidence interval: 19.2-22.6) per 10 000 births. The prevalence for each program ranged from 2.1 to 39.1 per 10 000 births. The international total prevalence increased 1.6 times during the study period, by 0.25 cases per 10 000 births per year (p Conclusions: Although there have been changes in clinical practice and registry ascertainment over time in some countries, the consistency in the observed increasing trends across many programs and by degrees of severity suggests that the total prevalence of hypospadias may be increasing in many countries. This observation is contrary to some previous reports that suggested that the total prevalence of hypospadias was no longer increasing in recent decades.Patient summary: We report on the prevalence and trends of hypospadias among 27 birth defect surveillance systems, which indicate that the prevalence of hypospadias continues to increase internationally.

Bile acids (BAs) are present in ovarian follicular fluid (FF) and are linked to embryo development. However, information on the source of ovarian BA is scarce. Therefore, we aimed to explore local ovarian synthesis and BA transport from blood into FF. BA levels were determined in matching FF and serum from women undergoing in vitro fertilization. In vitro BA production by human mural granulosa cells (MGCs) and cumulus granulosa cells (CGCs) was measured by mass spectrometry. Gene and protein expression were quantified in MGC and CGC and in human ovarian tissue by quantitative PCR and Western blot/immunohistochemistry, respectively. BA levels in blood and FF were significantly correlated (r(s) = 0.186, P = 0.027) but were almost twofold higher in FF (P

OBJECTIVE. Local ablation of hepatocellular carcinoma (HCC) before liver transplant has important advantages, such as preventing disease progression, tumor downstaging, and offering a test of time. However, it might render liver transplant more technically demanding Thus far, its potential effect on liver transplant outcomes is still unknown, and, therefore, the current study was performed.MATERIALS AND METHODS. Patients who underwent liver transplant for HCC at a single tertiary referral center between 2008 and 2016 were included and retrospectively analyzed. Patients who underwent liver resection and local ablation before liver transplant were excluded. Patients treated with local ablation before liver transplant were compared with those not treated with local ablation, both before and after propensity score matching In addition, the local ablation group was compared with patients who underwent primary resection before liver transplant. Posttreatment mortality and morbidity were determined, and overall and disease-free survival rates were calculated.RESULTS. In total, 182 patients were included. Twenty-six patients underwent resection but not local ablation before liver transplant. Of the remaining 156 patients, 66 (42%) underwent local ablation before liver transplant and 90 (58%) did not. Perioperative mortality and morbidity were similar in both groups before and after propensity score matching (8% and 74% in the local ablation group vs 10% and 83% in the non-local ablation group, p = 0.60 and 0.17, respectively). In addition, no significant differences in long-term outcomes were observed between the groups before and after propensity score matching Also, no differences were observed in outcomes in the local ablation group versus the liver resection group.CONCLUSION. Local ablation before liver transplant does not have a negative effect on outcomes after liver transplant for HCC.

Complete tumor removal during breast-conserving surgery remains challenging due to the lack of optimal intraoperative margin assessment techniques. Here, we use hyperspectral imaging for tumor detection in fresh breast tissue. We evaluated different wavelength ranges and two classification algorithms; a pixel-wise classification algorithm and a convolutional neural network that combines spectral and spatial information. The highest classification performance was obtained using the full wavelength range (450-1650nm). Adding spatial information mainly improved the differentiation of tissue classes within the malignant and healthy classes. High sensitivity and specificity were accomplished, which offers potential for hyperspectral imaging as a margin assessment technique to improve surgical outcome.

Background Vascular surgery has one of the highest unplanned 30‐day readmission rates of all surgical specialties. The degree to which these may be avoidable and the optimal strategies to reduce their occurrence are unknown. The aim of this study was to identify and classify avoidable 30‐day readmissions in patients undergoing vascular surgery in order to plan targeted interventions to reduce their occurrence, improve outcomes and reduce cost. Methods A retrospective analysis of discharges over a 12‐month period from a single tertiary vascular unit was performed. A multidisciplinary panel conducted a manual case‐note review to identify and classify those 30‐day unplanned emergency readmissions deemed avoidable. Results An unplanned 30‐day readmission occurred in 72 of 885 admissions (8·1 per cent). These unplanned readmissions were deemed avoidable in 36 (50 per cent) of these 72 patients, and were most frequently due to unresolved medical issues (19 of 36, 53 per cent) and inappropriate admission with the potential for outpatient management (7 of 36, 19 per cent). A smaller number were due to inadequate social care provision (4 of 36, 11 per cent) and the occurrence of other avoidable adverse events (4 of 36, 11 per cent). Conclusion Half of all 30‐day readmissions following vascular surgery are potentially avoidable. Multidisciplinary coordination of inpatient care and the transition from hospital to community care after discharge need to be improved., Fifty per cent of all unplanned 30‐day readmissions in patients undergoing vascular surgery are potentially avoidable. To reduce this burden, there is a need to take a multidisciplinary approach to optimizing medical care, support the transition from hospital to community care effectively, and develop targeted strategies to patients deemed to be at high risk. Many readmissions avoidable

Parenteral products must be compounded using an aseptic technique to ensure sterility of the medicine. We compared the effect of three clinical environments as compounding areas as well as different aseptic techniques on the sterility of the compounded parenteral product. Clinical pharmacists and pediatric nurses compounded 220 samples in total in three clinical environments: a patient room, a medicine room and biological safety cabinet. The study combined four methods: observation, environmental monitoring (settle plates), monitoring of personnel (finger dab plates) and sterility testing (membrane filtration). Of the compounded samples, 99% were sterile and no significant differences emerged between the clinical environments. Based on the settle plates, the biological safety cabinet was the only area that fulfilled the requirements for eliminating microbial contamination. Most of the steps on the observation form for aseptic techniques were followed. All participants disinfected their hands, wore gloves and disinfected the septum of the vial. Non-contaminated finger dab plates were mostly detected after compounding in the biological safety cabinet. Aseptic techniques were followed relatively well in all environments. However, these results emphasize the importance of good aseptic techniques and support the recommendation of compounding parenteral products in biological safety cabinets in clinical environments.

Background Clostridioides difficile infection (CDI) frequently complicates allogeneic hematopoietic stem cell (allo-HCT) and solid organ transplantation (SOT). Methods We retrospectively analyzed risk factors and outcomes of CDI occurring within 30 days of transplant. Results Between March 2010 and June 2015, 466 allo-HCT and 1454 SOT were performed. The CDI cumulative incidence (95% CI) was 10% (8-13) and 4% (3-5), following allo-HCT and SOT, respectively (p < .01), occurring at a median (range) 7.5 days (1-30) and 11 (1-30), respectively (p = .18). In multivariate analysis, fluoroquinolones use within 14 days pre-transplantation was a risk factor for CDI following allo-HCT (HR 4.06 [95% CI 1.31-12.63], p = .02), and thoracic organ(s) transplantation was a risk factor for CDI following SOT (HR 3.03 [95% CI 1.31-6.98]) for lung and 3.90 (1.58-9.63) for heart and heart/kidney transplant, p = .02. Compared with no-CDI patients, the length of stay (LOS) was prolonged in both allo-HCT (35 days [19-141] vs. 29 [13-164], p < .01) and SOT with CDI (16.5 [4-101] vs. 7 [0-159], p < .01), though not directly attributed to CDI. In allo-HCT, severe acute graft-versus-host disease (aGVHD) occurred more frequently in patients with CDI (33.3% vs. 15.8% without CDI, p = .01) and most aGVHD (87.5%) followed CDI. Non-relapse mortality or overall survival, not attributed to CDI, were also similar in both allo-HCT and SOT. Conclusions Early post-transplant CDI is frequent, associated with fluoroquinolones use in allo-HCT and the transplanted organ in SOT, and is associated with longer LOS in both the groups without difference in survival but with increased aGVHD in allo-HCT.

BACKGROUND: Venous thromboembolism (VTE) may be the first manifestation of occult cancer. Dementia has been linked to reduced cancer risk.OBJECTIVE: We examined the risk of cancer following VTE in people with dementia in comparison to the risk in the general population.METHODS: We conducted a population-based Danish registry-based cohort study following patients with a first-time VTE and a previous or concurrent diagnosis of dementia during the period 1 April 1996 -31 December 2017. We followed the study participants from date of VTE until diagnosis of cancer, death, emigration, or end of study period, whichever came first. The absolute risk of cancer within one year after VTE was computed, treating death as a competing risk. We calculated gender, age, and calendar-period standardized incidence ratios (SIRs) of cancer based on national cancer rates.RESULTS: We followed 3,552 people with dementia and VTE for a median of 1.3 years. Within the first year after VTE, they had a 90% increased risk of cancer in comparison with the general population [SIR: 1.9 (95% confidence interval: 1.6-2.4)]. During subsequent follow-up years, the SIR fell to 0.7 (95% confidence interval: 0.5-0.8). Findings for Alzheimer's disease and VTE were similar.CONCLUSION: People with dementia have an increased risk of a cancer diagnosis during the first year following VTE, perhaps related to increased surveillance, and a lower risk thereafter. Overall risk is similar to that of the general population.

Background Studying time-related changes in susceptible pathogens causing healthcare-associated infections (HAIs) is vital in improving local antimicrobial and infection control practices. Objectives Describe susceptibility patterns to several antimicrobials in gram-positive and gram-negative pathogens isolated from patients causing HAIs at three private tertiary care hospitals in Saudi Arabia over a 5-year period. Methods Data on trends of antimicrobial susceptibility among bacteria causing HAIs events in children and adults at three tertiary private hospitals located in Riyadh and Qassim, Saudi Arabia, were collected retrospectively between 2015 and 2019 using the surveillance data datasets. Results Over a 5-year period, 38,624 pathogens caused 17,539 HAI events in 17,566 patients. About 9450 (53.8%) of patients who suffered HAIs were females and the average age was 41.7 ± 14.3 years (78.1% were adults and 21.9% were children). Gram-negative pathogens were 2.3-times more likely to cause HAIs compared to gram-positive bacteria (71.9% vs. 28.1%). The ranking of causative pathogens in decreasing order was: Escherichia coli (38%), Klebsiella species (15.1%), and Staphylococcus aureus (12.6%). Gram-positive isolates were mostly susceptible to linezolid (91.8%) whereas they were resistant to ampicillin (52.6%), cefoxitin (54.2%), and doxycycline (55.9%). Gram-negative isolates were mostly sensitive to tigecycline (95%) whereas they were resistant to cefotaxime (49.5%) and cefixime (59.6%). During the 5 years, there were relatively stable susceptibility patterns to all tested antimicrobials, except for cefotaxime which shown a susceptibility reduction by 41.4%, among Escherichia coli and Klebsiella species. An increase in the susceptibility of Acinetobacter and Enterobacter and Citrobacter species to all studied antimicrobials was observed except for colistin that had a slight sensitivity reduction in 2019 by 4.3% against Acinetobacter species. However, we noted reduced sensitivity of MRSA, CoNS and Enterococcus species to gentamicin; and increased resistance of MRSA to linezolid and vancomycin. Conclusion The observed increase in susceptibility of gram-positive and gram-negative bacteria to studied antimicrobials is important; however, reduced sensitivity of MRSA, CoNS and Enterococcus species to gentamicin; and increased resistance of MRSA to linezolid and vancomycin is a serious threat and calls for effective antimicrobial stewardship programs.

© 2021 Taylor & Francis Group, LLC.Background: Immunosuppressive therapy has been a great concern during the pandemic. This study aimed to evaluate the pandemic's impact on psoriasis patients treated with immunosuppressive drugs. Material and Methods: The multicenter study was conducted in 14 tertiary dermatology centers. Demographic data, treatment status, disease course, and cases of COVID-19 were evaluated in patients with psoriasis using the immunosuppressive treatment. Results: Of 1827 patients included, the drug adherence rate was 68.2%. Those receiving anti-interleukin (anti-IL) drugs were more likely to continue treatment than patients receiving conventional drugs (OR = 1.50, 95% CI, 1.181–1.895, p =.001). Disease worsening rate was 24.2% and drug dose reduction increased this rate 3.26 and drug withdrawal 8.71 times. Receiving anti-TNF or anti-IL drugs was associated with less disease worsening compared to conventional drugs (p =.038, p =.032; respectively). Drug withdrawal causes were ‘unable to come’ (39.6%), ‘COVID concern’ (25.3%), and ‘physician’s and patient’s co-decision’ (17.4%). Four patients had COVID-19 infection with mild symptoms. The incidence was 0.0022% while it was 0.0025% in the general population. Conclusion: Our study shows that psoriasis patients using systemic immunosuppressive do not have a higher, but even lower COVID-19 risk than the general population, and treatment compliance with biological drugs is higher.

The objective of this retrospective, nationwide Finnish population-based cohort study was to determine whether there is an association between preterm caesarean breech delivery in the first pregnancy and maternal and neonatal morbidity in the subsequent pregnancy and delivery. We identified all singleton preterm breech birth in Finland from 2000 to 2017 (n = 1259) and constructed a data set of the first two deliveries for these women. We compared outcomes of the following pregnancy and delivery among women with a previous preterm caesarean breech section with the outcomes of women with one previous vaginal preterm breech birth. p Value, odds ratio, and adjusted odds ratio were calculated. Neonates of women with a previous caesarean preterm breech delivery had an increased risk for arterial umbilical cord pH below seven (1.2% versus 0%; p value .024) and a higher rate of neonatal intensive care unit admission [22.9% versus 15% adjusted OR 1.57 (1.13-2.18); p value

In non-alcoholic steatohepatitis (NASH), decreased nitric oxide and increased endothelin-1 (ET-1, also known as EDN1) released by sinusoidal endothelial cells (LSEC) induce hepatic stellate cell (HSC) contraction and contribute to portal hypertension (PH). Statins improve LSEC function, and ambrisentan is a selective endothelin-receptor-A antagonist. We aimed to analyse the combined effects of atorvastatin and ambrisentan on liver histopathology and hemodynamics, together with assessing the underlying mechanism in a rat NASH model. Diet-induced NASH rats were treated with atorvastatin (10 mg/kg/day), ambrisentan (30 mg/kg/day or 2 mg/kg/day) or a combination of both for 2 weeks. Hemodynamic parameters were registered and liver histology and serum biochemical determinations analysed. Expression of proteins were studied by immunoblotting. Conditioned media experiments were performed with LSEC. HSCs were characterized by RT-PCR, and a collagen lattice contraction assay was performed. Atorvastatin and ambrisentan act synergistically in combination to completely normalize liver hemodynamics and reverse histological NASH by 75%. Atorvastatin reversed the sinusoidal contractile phenotype, thus improving endothelial function, whereas ambrisentan prevented the contractile response in HSCs by blocking ET-1 response. Additionally, ambrisentan also increased eNOS (also known as Nos3) phosphorylation levels in LSEC, via facilitating the stimulation of endothelin-receptor-B in these cells. Furthermore, the serum alanine aminotransferase of the combined treatment group decreased to normal levels, and this group exhibited a restoration of the HSC quiescent phenotype. The combination of atorvastatin and ambrisentan remarkably improves liver histology and PH in a diet-induced NASH model. By recovering LSEC function, together with inhibiting the activation and contraction of HSC, this combined treatment may be an effective treatment for NASH patients., Summary: Combining atorvastatin with ambrisentan is safe and effective in reducing intrahepatic resistance and portal hypertension in an experimental model of NASH. This liver histology amelioration highlights a promising therapeutic strategy.
