Time Trends in Causes of Death in People with HIV: Insights from the Swiss HIV Cohort Study.

BACKGROUND: Advancements in access to antiretroviral therapy (ART) and human immunodeficiency virus (HIV) care have led to a decline in acquired immunodeficiency syndrome (AIDS)-related deaths among people with HIV (PWH) in Switzerland. However, data on the ongoing changes in causes of death among PWH over the past 15 years is scarce. METHODS: We investigated all reported deaths in the Swiss HIV Cohort Study between 2005-2022. Causes of death were categorized using the Coding Causes of Death in HIV protocol. The statistical analysis included demographic stratification to identify time trends and logistic regression models to determine associated factors for the underlying cause of death. RESULTS: In total, 1630 deaths were reported, with 23.7% of individuals assigned female at birth. Out of these deaths, 147 (9.0%) were HIV/AIDS-related, 373 (22.9%) due to non-AIDS, non-hepatic (NANH) cancers, 166 (10.2%) liver-related, and 158 (9.7%) cardiovascular-related. The median age at death increased from 45.0 [40.0,53.0] years in 2005-2007 to 61.0 [56.0,69.5] years in 2020-2022. HIV/AIDS and liver-related causes of death decreased, whereas deaths from NANH cancers increased, and cardiovascular-related deaths remained relatively stable. CONCLUSION: The proportionally decreasing HIV/AIDS and liver-related deaths showcase the effectiveness of ART, comprehensive HIV patient care, and interventions targeting hepatitis C virus co-infection. Future research should focus on managing cancer and cardiovascular-related conditions as the new leading causes of death among PWH. Comprehensive healthcare strategies focusing on non-AIDS-related comorbidities, cancer management, and sustaining liver and cardiovascular health are needed to bridge the ongoing health disparities between PWH and the general population.

Corpse or not? Two peculiar cases of misidentification.

Irrespective of whether they are intended for collectors or for the fetish market, dolls are being produced to look more and more realistic with such a degree of life-like detail that they can be mistaken for a real person. This paper reports two cases of misidentification due to this increasing similarity: In the first case, a sex doll was mistaken for a corpse; in the second case, a corpse was mistaken for a doll. While in the latter case, only medical laypersons were at the discovery site, in the first case, an emergency doctor had issued a medical certificate of death for the purported corpse. The medicolegal examiner who was subsequently called to the scene could still rectify the misconception on-site. Mistakes of this nature are likely rare phenomena. It, however, remains to be seen if the increasingly life-like appearance of dolls on the one hand, and the increasingly doll-like appearance of some people, e.g., through cosmetic surgery, will lead to a rise in such cases. To avoid misidentification as in the first reported case, it is essential to prepare medical students well for the task of performing a primary external postmortem examination; it is equally important that fully-trained doctors regularly refresh their expertise in this respect.

Fast, High-Fidelity Addressed Single-Qubit Gates Using Efficient Composite Pulse Sequences.

We use electronic microwave control methods to implement addressed single-qubit gates with high speed and fidelity, for ^{43}Ca^{+} hyperfine "atomic clock" qubits in a cryogenic (100 K) surface trap. For a single qubit, we benchmark an error of 1.5×10^{-6} per Clifford gate (implemented using 600 ns π/2 pulses). For 2 qubits in the same trap zone (ion separation 5 µm), we use a spatial microwave field gradient, combined with an efficient four-pulse scheme, to implement independent addressed gates. Parallel randomized benchmarking on both qubits yields an average error 3.4×10^{-5} per addressed π/2 gate. The scheme scales theoretically to larger numbers of qubits in a single register.

Robust Quantum Memory in a Trapped-Ion Quantum Network Node.

We integrate a long-lived memory qubit into a mixed-species trapped-ion quantum network node. Ion-photon entanglement first generated with a network qubit in ^{88}Sr^{+} is transferred to ^{43}Ca^{+} with 0.977(7) fidelity, and mapped to a robust memory qubit. We then entangle the network qubit with a second photon, without affecting the memory qubit. We perform quantum state tomography to show that the fidelity of ion-photon entanglement decays ∼70 times slower on the memory qubit. Dynamical decoupling further extends the storage duration; we measure an ion-photon entanglement fidelity of 0.81(4) after 10 s.

Field-Tunable Berezinskii-Kosterlitz-Thouless Correlations in a Heisenberg Magnet.

We report the manifestation of field-induced Berezinskii-Kosterlitz-Thouless (BKT) correlations in the weakly coupled spin-1/2 Heisenberg layers of the molecular-based bulk material [Cu(pz)_{2}(2-HOpy)_{2}](PF_{6})_{2}. At zero field, a transition to long-range order occurs at 1.38 K, caused by a weak intrinsic easy-plane anisotropy and an interlayer exchange of J^{'}/k_{B}≈1 mK. Because of the moderate intralayer exchange coupling of J/k_{B}=6.8 K, the application of laboratory magnetic fields induces a substantial XY anisotropy of the spin correlations. Crucially, this provides a significant BKT regime, as the tiny interlayer exchange J^{'} only induces 3D correlations upon close approach to the BKT transition with its exponential growth in the spin-correlation length. We employ nuclear magnetic resonance measurements to probe the spin correlations that determine the critical temperatures of the BKT transition as well as that of the onset of long-range order. Further, we perform stochastic series expansion quantum Monte Carlo simulations based on the experimentally determined model parameters. Finite-size scaling of the in-plane spin stiffness yields excellent agreement of critical temperatures between theory and experiment, providing clear evidence that the nonmonotonic magnetic phase diagram of [Cu(pz)_{2}(2-HOpy)_{2}](PF_{6})_{2} is determined by the field-tuned XY anisotropy and the concomitant BKT physics.

PET/CT-identified atrial hypermetabolism is an index of atrial inflammation in patients with atrial fibrillation.

BACKGROUND: Although atrial inflammation has been implicated in the pathophysiology of atrial fibrillation (AF), the identification of atrial inflammation remains challenging. We aimed to establish a positron emission tomography/computed tomography (PET/CT) protocol with 18Fluor-labeled fluorodeoxyglucose (18F-FDG) for the detection of atrial hypermetabolism as surrogate for inflammation in AF. METHODS: We included n = 75 AF and n = 75 non-AF patients undergoing three common PET/CT protocols (n = 25 per group) optimized for the detection of (a) inflammation and (b) malignancy in predefined fasting protocols, and (c) cardiac viability allowing for maximized glucose uptake. 18F-FDG-uptake was analyzed in predefined loci. RESULTS: Differences of visual atrial uptake in AF vs non-AF patients were observed in fasting (inflammation [13/25 vs 0/25] and malignancy [10/25 vs 0/25]) protocols while viability protocols showed non-specific uptake in both the groups. In the inflammation protocol, AF patients showed higher uptake in the right atrium [(SUVmax: 2.5 ± .7 vs 2.0 ± .7, P = .01), atrial appendage (SUVmax: 2.4 ± .7 vs 2.0 ± .6, P = .03), and epicardial adipose tissue (SUVmax: 1.4 ± .5 vs 1.1 ± .4, P = .04)]. Malignancy and viability protocols failed to differentiate between AF and non-AF. CONCLUSION: Glucose uptake suppression protocols appear suitable in detecting differential atrial 18F-FDG uptake between AF and non-AF patients. Imaging-based assessment of inflammation might help to stratify AF patients offering individualized therapeutic approaches.

Femur development in fetal growth restriction as observed on prenatal magnetic resonance imaging.

OBJECTIVE: To investigate human femur development in fetal growth restriction (FGR) by analyzing femur morphometrics and distal epimetaphyseal features on prenatal magnetic resonance imaging (MRI). METHODS: This was a retrospective study of 111 fetuses (mean gestational age (GA), 27 + 2 weeks (range, 19-35 weeks)) with FGR associated with placental insufficiency without other major abnormalities and 111 GA-matched normal controls. On 1.5-Tesla echoplanar MRI, femur morphometrics, including diaphyseal length, epiphyseal length and epiphyseal width, were assessed. Using a previously reported grading system, epimetaphyseal features, including cartilaginous epiphyseal shape, metaphyseal shape and epiphyseal ossification, were analyzed qualitatively. To compare FGR cases and controls, the paired t-test was used to assess morphometrics, generalized estimating equations were used for epimetaphyseal features and time-to-event analysis was used to assess the visibility of epiphyseal ossification. RESULTS: There were significant differences in femur morphometrics between FGR cases and controls (all parameters, P < 0.001), with bone shortening observed in FGR. No significant differences were found in the distribution of epimetaphyseal features between FGR cases and controls (epiphyseal shape, P = 0.341; metaphyseal shape, P = 0.782; epiphyseal ossification, P = 0.85). Epiphyseal ossification was visible at a median of 33.6 weeks in FGR cases and at 32.1 weeks in controls (P = 0.008). CONCLUSIONS: On prenatal MRI, cases with FGR associated with placental insufficiency exhibit diaphyseal and epiphyseal shortening of the femur. However, FGR cases and normal controls share similarly graded distal epimetaphyseal features. Consequently, these features may not be appropriate MRI characteristics for the identification of FGR. © 2022 The Authors.

Prophylactic clipping using the over-the-scope clip (OTSC) system after complex ESD and EMR of large colon polyps.

BACKGROUND: Delayed bleeding is the most frequent complication after endoscopic submucosal dissection (ESD) and endoscopic mucosal resection (EMR) of large colon polyps. Today, prophylactic clipping with through-the-scope clips (TTSCs) is commonly used to reduce the risk of bleeding. However, the over-the-scope clip (OTSC) system might be superior to TTSCs in achieving hemostasis. This study aims to evaluate the efficacy and safety of prophylactic clipping using the OTSC system after ESD or EMR of large colon polyps. METHODS: This is a retrospective analysis of a prospective collected database from 2009 until 2021 of three endoscopic centers. Patients with large (≥ 20 mm) colon polyps were enrolled. All polyps were removed by either ESD or EMR. After the resection, OTSCs were prophylactically applied on parts of the mucosal defect with a high risk of delayed bleeding or/and perforation. The main outcome measurement was delayed bleeding. RESULTS: A total of 75 patients underwent ESD (67%, 50/75) or EMR (33%, 25/75) in the colorectum. The mean resected specimen diameter was 57 mm ± 24.1 (range 22-98 mm). The mean number of OTSCs placed on the mucosal defect was 2 (range 1-5). None of the mucosal defects were completely closed. Intraprocedural bleeding occurred in 5.3% (ESD 2.0% vs. EMR 12.0%; P = 0.105), and intraprocedural perforation occurred in 6.7% (ESD 8% vs. EMR 4%; P = 0.659) of the patients. Hemostasis was achieved in 100% of cases of intraprocedural bleeding, whereas two patients required surgical conversion due to intraprocedural perforation. Among the remaining 73 patients who received prosphylactic clipping, delayed bleeding occurred in 1.4% (ESD 0% vs. EMR 4.2%; P = 0.329), and delayed perforation occurred in 0%. CONCLUSIONS: The prophylactic partial closure of large post-ESD/EMR mucosal defects using OTSCs could serve as an effective strategy to reduce the risk of delayed bleeding and perforation. The prophylactic partial closure of large complex post-ESD/EMR mucosal defects using OTSCs could serve as an effective strategy to reduce the risk of delayed bleeding and perforation.

EANM procedure guideline for the treatment of liver cancer and liver metastases with intra-arterial radioactive compounds.

Primary liver tumours (i.e. hepatocellular carcinoma (HCC) or intrahepatic cholangiocarcinoma (ICC)) are among the most frequent cancers worldwide. However, only 10-20% of patients are amenable to curative treatment, such as resection or transplant. Liver metastases are most frequently caused by colorectal cancer, which accounts for the second most cancer-related deaths in Europe. In both primary and secondary tumours, radioembolization has been shown to be a safe and effective treatment option. The vast potential of personalized dosimetry has also been shown, resulting in markedly increased response rates and overall survival. In a rapidly evolving therapeutic landscape, the role of radioembolization will be subject to changes. Therefore, the decision for radioembolization should be taken by a multidisciplinary tumour board in accordance with the current clinical guidelines. The purpose of this procedure guideline is to assist the nuclear medicine physician in treating and managing patients undergoing radioembolization treatment. PREAMBLE: The European Association of Nuclear Medicine (EANM) is a professional non-profit medical association that facilitates communication worldwide among individuals pursuing clinical and research excellence in nuclear medicine. The EANM was founded in 1985. These guidelines are intended to assist practitioners in providing appropriate nuclear medicine care for patients. They are not inflexible rules or requirements of practice and are not intended, nor should they be used, to establish a legal standard of care. The ultimate judgment regarding the propriety of any specific procedure or course of action must be made by medical professionals taking into account the unique circumstances of each case. Thus, there is no implication that an approach differing from the guidelines, standing alone, is below the standard of care. To the contrary, a conscientious practitioner may responsibly adopt a course of action different from that set out in the guidelines when, in the reasonable judgment of the practitioner, such course of action is indicated by the condition of the patient, limitations of available resources or advances in knowledge or technology subsequent to publication of the guidelines. The practice of medicine involves not only the science but also the art of dealing with the prevention, diagnosis, alleviation and treatment of disease. The variety and complexity of human conditions make it impossible to always reach the most appropriate diagnosis or to predict with certainty a particular response to treatment. Therefore, it should be recognised that adherence to these guidelines will not ensure an accurate diagnosis or a successful outcome. All that should be expected is that the practitioner will follow a reasonable course of action based on current knowledge, available resources and the needs of the patient to deliver effective and safe medical care. The sole purpose of these guidelines is to assist practitioners in achieving this objective.

Equivalent tumor detection for early and late FAPI-46 PET acquisition.

INTRODUCTION: Positron emission tomography (PET) using small ligands of the fibroblast activation protein (FAP) was recently introduced. However, optimal uptake time has not been defined yet. Here, we systematically compare early (~ 10 min p.i.) and late (~ 60 min p.i.) FAPI-46 imaging in patients with various types of cancer. METHODS: This is a retrospective single-institutional study. Imaging was performed at the Essen University Hospital, Germany. A total of 69 patients who underwent dual time-point imaging for either restaging (n = 52, 75%) or staging (n = 17, 25%) of cancer were included. Patients underwent PET with two acquisitions: early (mean 11 min, SD 4) and late (mean 66 min, SD 9). Mean injected activity was 148 MBq (SD 33). RESULTS: In total, 400 lesions were detected in 69 patients. Two of 400 (0.5%) lesions were only seen in early time-point imaging but not in late time-point imaging. On a per-patient level, there was no significant difference between SUVmax of hottest tumor lesions (Wilcoxon: P = 0.73). Organ uptake demonstrated significant early to late decrease in SUVmean (average ∆SUVmean: - 0.48, - 0.14, - 0.27 for gluteus, liver, and mediastinum, respectively; Wilcoxon: P < 0.001). On a per-lesion basis, a slight increase of SUVmax was observed (average ∆SUVmax: + 0.4, Wilcoxon: P = 0.03). CONCLUSION: In conclusion, early (~ 10 min p.i.) versus late (~ 60 min p.i.) FAPI-46 imaging resulted in equivalent lesion uptake and tumor detection. For improved feasibility and scan volume, we implement early FAPI-46 PET in future clinical and research protocols.

Use of Pre- and Intensified Postprocedural Physiotherapy in Patients with Symptomatic Aortic Stenosis Undergoing Transcatheter Aortic Valve Replacement Study (the 4P-TAVR Study).

BACKGROUND: Physiotherapy prior to open-heart surgery lowers the rate of pneumonia and length of the hospital stay. Pneumonia is a major contributor to short-term mortality following transcatheter aortic valve replacement (TAVR). Hence, we hypothesized that pre- and intensified postprocedural physiotherapy in patients undergoing TAVR might impact the net functional and clinical outcome. METHODS AND RESULTS: The 4P-TAVR study was a prospective, monocentric, randomized trial. The study was designed to compare the efficacy and safety of intensified periprocedural physiotherapy including inspiratory muscle training versus standard postprocedural physiotherapy. Patients were randomized in a 1 : 1 fashion. 108 patients were included and followed up for 90 days after TAVR. While patients in group A (control group: 50 patients, age: 81.7 ± 5.0 years, 52% male) did not receive physiotherapy prior to TAVR, group B (intervention group: 58 patients, age: 82.2 ± 5.82 years, 47% male) participated in intensive physiotherapy. Compared to the control group, patients in the interventional group showed a lower incidence of postinterventional pneumonia (10 [20.0%] vs. 3 [5.1%], p=0.016) and had a 3-day shorter mean hospital stay (13.5 ± 6.1 days vs. 10.1 ± 4.7 days, p=0.02). The primary composite endpoint of mortality and rehospitalization was not different between the groups. CONCLUSION: Intensified physiotherapy is safe and has positive effects on clinical outcomes up to 90 days after TAVR but has no impact on the primary combined endpoint of mortality and rehospitalization. Longer follow-up, a multicenter design, and a higher number of subjects are needed to confirm these preliminary results. This trial is registered with DRKS00017239.

Intestinal anastomotic healing models during experimental colitis.

BACKGROUND: Anastomotic leakage represents a major complication following resections in colorectal surgery. Among others, intestinal inflammation such as in inflammatory bowel disease is a significant risk factor for disturbed anastomotic healing. Despite technical advancements and several decades of focused research, the underlying mechanisms remain incompletely understood. Animal experiments will remain the backbone of this research in the near future. Here, instructions on a standardized and reproducible murine model of preoperative colitis and colorectal anastomosis formation are provided to amplify research on anastomotic healing during inflammatory disease. METHODS: We demonstrate the combination of experimental colitis and colorectal anastomosis formation in a mouse model. The model allows for monitoring of anastomotic healing during inflammatory disease through functional outcomes, clinical scores, and endoscopy and histopathological examination, as well as molecular analysis. DISCUSSION: Postoperative weight loss is used as a parameter to monitor general recovery. Functional stability can be measured by recording bursting pressure and location. Anastomotic healing can be evaluated macroscopically from the luminal side by endoscopic scoring and from the extraluminal side by assessing adhesion and abscess formation or presence of dehiscence. Histologic examination allows for detailed evaluation of the healing process. CONCLUSION: The murine model presented in this paper combines adjustable levels of experimental colitis with a standardized method for colorectal anastomosis formation. Extensive options for sample analysis and evaluation of clinical outcomes allow for detailed research of the mechanisms behind defective anastomotic healing.

Improved neurodevelopmental prognostication in isolated corpus callosal agenesis: fetal magnetic resonance imaging-based scoring system.

OBJECTIVES: Corpus callosal agenesis (CCA) is one of the most common brain malformations and is generally associated with a good outcome when isolated. However, up to 25% of patients are at risk of neurodevelopmental delay, which currently available clinical and imaging parameters are inadequate to predict. The objectives of this study were to apply and validate a fetal magnetic resonance imaging (MRI) anatomical scoring system in a cohort of fetuses with isolated CCA and to evaluate the correlation with postnatal neurodevelopmental outcome. METHODS: This was a retrospective cohort study of cases of prenatally diagnosed isolated CCA (as determined on ultrasound and MRI), with normal karyotype and with known postnatal neurodevelopmental outcome assessed by standardized testing. A fetal brain MRI anatomical scoring system based on seven categories (gyration, opercularization, temporal lobe symmetry, lamination, hippocampal position, basal ganglia and ventricular size) was developed and applied to the cohort; a total score of 0-11 points could be given, with a score of 0 representing normal anatomy. Images were scored independently by two neuroradiologists blinded to the outcome. For the purpose of assessing the correlation between fetal MRI score and neurodevelopmental outcome, neurodevelopmental test results were scored as follows: 0, 'below average' (poor outcome); 1, 'average'; and 2, 'above average' (good outcome). Spearman's rank coefficient was used to assess correlation, and inter-rater agreement in the assessment of fetal MRI score was calculated. RESULTS: Twenty-one children (nine females (42.9%)) fulfilled the inclusion criteria. Thirty-seven fetal MRI examinations were evaluated. Mean gestational age was 28.3 ± 4.7 weeks (range, 20-38 weeks). All fetuses were delivered after 35 weeks' gestation with no perinatal complications. Fetal MRI scores ranged from 0 to 6 points, with a median of 3 points. Inter-rater agreement in fetal MRI score assessment was excellent (intraclass correlation coefficient, 0.959 (95% CI, 0.921-0.979)). Neurodevelopmental evaluation was performed on average at 2.6 ± 1.46 years (range, 0.5-5.8 years). There was a significant negative correlation between fetal MRI score and neurodevelopmental outcome score in the three areas tested: cognitive (ρ = -0.559, P < 0.0001); motor (ρ = -0.414, P = 0.012) and language (ρ = -0.565, P < 0.0001) skills. Using fetal MRI score cut-offs of ≤ 3 (good outcome) and ≥ 4 points (high risk for poor outcome), the correct prognosis could be determined in 20/21 (95.2% (95% CI, 77.3-99.2%)) cases. CONCLUSION: By assessing structural features of the fetal brain on MRI, it may be possible to better stratify prenatally the risk of poor neurodevelopmental outcome in CCA patients. © 2020 Authors.

Normal human brainstem development in vivo: a quantitative fetal MRI study.

OBJECTIVES: To characterize spatiotemporal growth differences of prenatal brainstem substructures and cerebellum, using linear biometry and planimetry on fetal magnetic resonance imaging (MRI). METHODS: In this retrospective study, we included fetuses with normal brain and a precise midsagittal T2-weighted brain MRI sequence obtained between May 2003 and April 2019. The cross-sectional area, rostrocaudal diameter and anteroposterior diameter of the midbrain, pons (basis pontis and pontine tegmentum), medulla oblongata and cerebellar vermis, as well as the transverse cerebellar diameter, were quantified by a single observer. The diameters were also assessed by a second observer to test inter-rater variability. RESULTS: We included 161 fetuses with normal brain and a precise midsagittal MRI sequence, examined at a mean ± SD gestational age of 25.7 ± 5.4 (range, 14 + 0 to 39 + 2) weeks. All substructures of the fetal brainstem and the cerebellum could be measured consistently (mean ± SD interobserver intraclass correlation coefficient, 0.933 ± 0.065). We provide reference data for diameters and areas of the brainstem and cerebellum in the second and third trimesters. There was a significant quadratic relationship between vermian area and gestational age, and all other measured parameters showed a significant linear growth pattern within the observed period (P < 0.001). A significant change in the relative proportions of the brainstem substructures occurred between the beginning of the second trimester and the end of the third trimester, with an increase in the area of the pons (P < 0.001) and a decrease in that of the midbrain (P < 0.001), relative to the total brainstem area. CONCLUSIONS: The substructures of the fetal brainstem follow a distinct spatiotemporal growth pattern, characterized by a relative increase in the pons and decrease in the midbrain, between 15 and 40 weeks of gestation. Caution is needed when interpreting fetal brainstem appearance during the early second trimester, as the brainstem proportions differ significantly from the adult morphology. The reference data provided herein should help to increase diagnostic accuracy in detecting disorders of defective hindbrain segmentation. © 2020 The Authors.

A research primer for studies of cognitive changes across the menopause transition.

There has been a proliferation of studies demonstrating important sex differences in cognitive aging and dementia, and with this an increased interest in the role of menopause and sex steroid hormones in women's brain health. Foundational longitudinal studies of cognitive changes from the premenopause to perimenopause stage have shown reliable declines in verbal memory, with variable findings in processing speed, attention/working memory and verbal fluency. Continued research is needed to advance understanding of the range of cognitive domains affected, the duration of cognitive changes, the generalizability of these changes across cultures, the factors that account for such changes and the factors that can improve cognition at this time. In this article, we briefly review and draw on findings from large longitudinal studies of cognitive changes across the menopause transition to inform the design of future studies on this topic. We focus on key issues such as objective versus subjective cognitive measures; cognitive domains and tests; staging menopause; study design; mediators of cognitive effects (including hormones and menopause symptoms); and consideration of key covariates. We suggest that a more uniform and evidence-based approach to the investigation of these issues can advance the quality of the science in menopause and cognition.

Cognitive profiles in perimenopause: hormonal and menopausal symptom correlates.

OBJECTIVE: Perimenopause is associated with declines in attention, working memory and verbal memory; however, there are significant individual differences. Further, the contributions of hormones and menopausal symptoms to domain-specific cognitive functions remain unknown. This longitudinal study aimed to determine whether there were distinct cognitive profiles in perimenopause and to identify factors associated with each profile. DESIGN: In a sample of 85 women evaluated over 400 bi-annual visits, we administered a comprehensive neuropsychological battery, assessed menopausal symptoms and measured 17ß-estradiol and follicle stimulating hormone. Multilevel latent profile analysis was used to identify cognitive profiles. Regressions were conducted to determine differences in hormones and symptoms by profile after adjusting for Stages of Reproductive Aging Workshop + 10 (STRAW + 10) stage and demographic factors. RESULTS: Perimenopausal cognitive profiles consisted of cognitively normal (Profile 1; n = 162), weaknesses in verbal learning and memory (Profile 2; n = 94), strengths in verbal learning and memory (Profile 3; n = 98) and strengths in attention and executive function (Profile 4; n = 61). Profile 2 was differentiated by less hormonal variability and more sleep disturbance than Profile 1 (p < 0.05). CONCLUSIONS: There is significant heterogeneity in cognition during perimenopause. While most women do not develop impairments, a significant minority experience weaknesses in verbal learning and memory. Profile analysis may identify at-risk populations and inform interventions.

[The anesthesiological questionnaire for patients in the outpatient context : Investigations on patient state of health after outpatient operations using the anesthesiological questionnaire for patients]. / Der Anästhesiologische Nachbefragungsbogen für Patienten im ambulanten Kontext : Untersuchungen zum Patientenbefinden nach ambulanten Operationen mithilfe des Anästhesiologischen Nachbefragungsbogen für Patienten.

BACKGROUND: The evaluation of German postanesthesia questionnaires is often restricted to inpatient medical care. The anesthesiological questionnaire for patients (ANP) has previously been validated only after medical care of inpatients. Therefore, the aim of the present study was to evaluate the validity of the ANP in the context of outpatient surgery and anesthesia. METHODS: Data from 4547 patients (mean age 18-89 years, sex: m/f, 55%/45%), scheduled for ambulatory orthopedic and trauma surgery, were analyzed. All patients received a standard induction of anesthesia with propofol, sufentanil and 4 mg dexamethasone. Maintenance of anesthesia was achieved with a balanced technique comprising volatile anesthesia (either sevoflurane or desflurane) and sufentanil. In addition, patients undergoing operations on the anterior cruciate ligament received a femoral nerve block with 12-15 ml 0.5% ropivacaine. Of the patients 13% remained in hospital overnight as a result of complex operations (combined anterior and posterior cruciate ligament repair, hip arthroscopy and 10% of those undergoing shoulder operations). Before discharge from the recovery room, patients were asked to answer questions with respect to postoperative symptoms 1h after anesthesia (ESNA 19 items), at the time of interview (ABZ 17 items) and about overall patient satisfaction (10 items). These results were matched with the type of procedure and time data from the patient administration system. All data were analyzed descriptively using parametrical tests. RESULTS: At both time points, pain in the area of the operation was the predominant symptom (ESNA: 77,1%; ABZ: 74,3%). Pain after shoulder arthroscopy was more severe compared to knee arthroscopy, both with and without repair of the anterior cruciate ligament. Most of the adverse symptoms decreased significantly (p ≤ 0.001) with time, demonstrating progressive recovery of the patient. Patient discomfort was more likely to occur in female than in male patients, and female patients were more likely to be dissatisfied with the progress of recovery. The risk of experiencing adverse symptoms after anesthesia was higher for female than for male patients; this was most apparent for feeling cold (odds ratio, OR 4.08) and nausea and vomiting (OR 3.45). Younger patients (18-40 years) were more likely to express discomfort than both groups of older patients (41-60 years and 61-89 years). Accordingly, younger patients had lower satisfaction levels with respect to both anesthesia and overall perioperative care, and the progress of recovery. Postoperative nausea and vomiting (PONV) were linked to younger age, female sex, and longer procedure times (>40 min). CONCLUSION: The individual analyses delivered plausible results, which support the validity of the ANP. The ANP may also be used for assessment of postoperative discomfort and patient satisfaction in the setting of outpatient surgery. In view of the short time interval between the two measurement points, the ANP for outpatients could in future be reduced to a single postoperative questionnaire.

[A several-week history of inflammatory changes in the right foot and right hand of a 57-year-old male patient]. / Seit mehreren Wochen bestehende entzündliche Veränderungen an rechtem Fuß und rechter Hand bei einem 57-jährigen Patienten.

Metastatic fat necrosis due to inflammatory or neoplastic pancreatic diseases is rare. This phenomenon is attributed to systemic effects of pancreatic enzymes. Depending on the sites of fat necrosis, a number of different diseases may be mimicked, leading to incorrect diagnosis and therapies. Many case reports describe the phenomenon of skin, joint and bone manifestations of fat necrosis under the acronym PPP (pancreatic, panniculits, polyarthritis) syndrome. The management of "autodigestion" primarily consists of treating the underlying pancreatic disease.

Potential predictive value of axial T2 mapping at 3 Tesla MRI in patients with untreated patellar cartilage defects over a mean follow-up of four years.

OBJECTIVE: The objective was to demonstrate the potential of axial T2 mapping for quantification of untreated early-stage patellar cartilage lesions over time and to assess its capability as a potential predictive marker for future progression. STUDY DESIGN & METHODS: Thirty patients (mean age, 36.7 ± 11.1 years; 16 males), with early-stage patellar cartilage defects (≤ICRS grade 2) at baseline and no treatment during follow up (4.0 ± 1.6 years) were enrolled. Morphological cartilage changes over time were subdivided into a Progression, Non-Progression Group and Regression Group. Quantitative analysis of cartilage defects and healthy reference was performed by means of global and zonal T2 mapping (deep and superficial cartilage T2 values) at both time points. Statistical evaluation included analysis of variance (ANOVA), paired t Test's and ROC analysis. RESULTS: The Progression Group (N = 11) had significantly higher global T2 values at baseline (57.4 ± 7.8 ms) than patients without (N = 17) (40.6 ± 6.9 ms) (P < 0.01). Furthermore the Non-Progression Group showed only a minor increase in global T2 relaxation times to 43.1 ± 7.9 ms (P = 0.07) at follow up, whereas in the progression group global (68,7 ± 19 ms: P = 0.02) and superficial T2 values (65,8 ± 8.2-79.8 ± 24.4 ms; P = 0.03) increased significantly. T2 values for healthy reference cartilage remained stable. In 2 patients an improvement in ICRS grading was observed (Regression Group) with decreasing T2 values. The ROC analysis showed an area under the curve of 0.92 (95%CI 0.82-1.0). At a cut-off value of 47.15 ms, we found a sensitivity of 92% (false-positive rate of 18%) for future progression of cartilage defects. CONCLUSIONS: This study provides evidence regarding the possible potential of axial T2 mapping as a tool for quantification and prediction of patellar cartilage defect progression in untreated defects.

First Germanium-Based Constraints on Sub-MeV Dark Matter with the EDELWEISS Experiment.

We present the first Ge-based constraints on sub-MeV/c^{2} dark matter (DM) particles interacting with electrons using a 33.4 g Ge cryogenic detector with a 0.53 electron-hole pair (rms) resolution, operated underground at the Laboratoire Souterrain de Modane. Competitive constraints are set on the DM-electron scattering cross section, as well as on the kinetic mixing parameter of dark photons down to 1 eV/c^{2}. In particular, the most stringent limits are set for dark photon DM in the 6 to 9 eV/c^{2} range. These results demonstrate the high relevance of Ge cryogenic detectors for the search of DM-induced eV-scale electron signals.
