RESUMO
Insomnia is a common feature of depression; however, depression treatment guidelines provide limited recommendations regarding hypnotic drugs. Few studies have thoroughly investigated the use of hypnotic drugs in depression. In this cohort study using national Swedish registers, we included all patients ≥18 years with incident unipolar depression during 2007-2017. Patients were followed for 3 years, noting the annual and quarterly prevalence of hypnotic drug use from prescription fills. Prevalence ratios (PR) comparing 2017 to 2007 were calculated with 95% confidence intervals (CI). A total of 222,077 patients with depression were included (mean age 41 years, 59% women). In the year following diagnosis, 44.1% used any hypnotic drug in 2017, compared with 46.7% in 2007 (PR 0.94, 95% CI 0.92-0.97). The most commonly used drugs were Z-drugs (zopiclone, zolpidem, and zaleplon) with a prevalence of 27.6% in 2017 and 35.6% in 2007 (PR 0.78, 95% CI 0.75-0.80). Melatonin use increased sharply to 12.0% in 2017 from 0.4% in 2007 (PR 28.9, 95% CI 23.5-35.7). Hypnotic drug use was most prevalent in the first two quarters after diagnosis; however, after 3 years, the quarterly prevalence was still 19.2%. Hypnotics were more common among women, older patients, those with somatic comorbidities, more severe depression, or a history of suicide attempt. Evidence from this large register-based study demonstrates that hypnotics were used to a large extent in depression in Sweden 2007-2017. Z-drugs use declined and melatonin use increased dramatically. Hypnotic drug use remained high even 3 years after diagnosis.
RESUMO
Meralgia paraesthetica (MP) is the consequence of an entrapment or stretch injury of the lateral femoral cutaneous nerve at the crossing region with the inguinal ligament where the nerve exits the pelvis. It results in temporary or permanent sensory loss, paraesthesia and pain in the anterolateral region of the thigh. Idiopathic forms are known for example as seat belt syndrome or jeans syndrome. An MP can also occur as a complication of surgical or intensive care patient positioning. In focus are the lithotomy position, prone position and beach chair position.We analyzed 21 complaints about MP occurring for the first time postoperatively, which had been submitted to the expert committee for medical treatment errors at the North Rhine Medical Association over the past 10 years. Among these, six cases could be identified as positioning damage after a lithotomy position. In three cases MP occurred after supine positioning but the etiology could not be clarified with certainty. In 12 cases MP was recognized as a direct surgical complication.The pathophysiology, incidence and course as well as legal implications of position-related MP are discussed. Pressure damage to the nerve at its intersection with the inguinal ligament is assumed to be the main pathomechanism. Although all the cases presented here occurred after lithotomy positioning, the complication also appears to occur with other types of positioning according to the literature data, the most common being prone positioning. This also explains the increasingly published case reports of MP after prone positioning in COVID-19 patients for respiratory treatment. Safe avoidance of the positioning-related complication does not appear to be possible due to the anatomical variability of the course of the nerve and the unclear pathomechanisms.

Two randomized controlled trials (RCTs) in Brazil and Peru demonstrated the effectiveness of CONEMO, a digital intervention supported by trained nurses or nurse assistants (NAs), to reduce depressive symptoms in people with diabetes and/or hypertension. This paper extends the RCTs findings by reflecting on the conditions needed for its wider implementation in routine care services. A qualitative study using semi-structured interviews and content analysis was conducted with nurses/NAs, clinicians, healthcare administrators, and policymakers. Informants reported that CONEMO would be feasible to implement in their health services, but some conditions could be improved before its scale-up: reducing workloads of healthcare workers; raising mental health awareness among clinicians and administrators; being able to inform, deliver and accompany the intervention; assuring appropriate training and supervision of nurses/NAs; and supporting the use of technology in public health services and by patients, especially older ones. We discuss some suggestions on how to overcome these challenges.
RESUMO
Because of a painful right-sided coxarthrosis a 57-year-old female patient underwent a cementless total arthroplasty under general anesthesia. Except for Asperger's syndrome and an occlusion of a vein in her left eye she stated no other diseases or complaints, especially no cardiac problems. Postoperatively she developed neurological symptoms of left-sided hemiparesis and hemihypesthesia. A cranial computer tomography was performed and a right-sided infarction of the thalamic region was found. A patent foramen ovale (PFO) and atrial septal aneurysm were detected 5 days later. The incidence of a PFO is given as 25% of the population. A paradoxical air embolism in the presence of a PFO is a feared complication in neurosurgical interventions in a semi-sitting or sitting position. Corpuscular emboli, such as bone, cement, fat or wound debris may be the reason for paradoxical embolisms in combination especially with partial or total hip replacement. The kind of embolism in the case described could not be clarified. Deep vein thrombosis or cardiac arrhythmia could be excluded. Therefore, it can be considered most likely that the operation site was the source of the embolism. The trigger for a paradoxical embolism is a reversal of the pressure difference between the right and left atria: normally the left atrial pressure exceeds the right atrial pressure by ca. 2-4â¯mmâ¯Hg, resulting possibly in a small clinically irrelevant left-to-right shunt. If the pulmonary arterial circulation is compromised and pulmonary vascular resistance increases, the pressure gradient between the left and right atria reverses and a right-to-left shunt can occur causing a paradoxical embolism. Positive end-expiratory pressure (PEEP) ventilation during anesthesia could be an important reason for a shunt reversal between the right and left atria and therefore favoring a paradoxical embolism but the pathophysiological role of PEEP has not yet been finally clarified.

A 61-year-old woman underwent a tension-free vaginal tape (TVT) operation due to stress incontinence. After technically difficult spinal anesthesia with two attempts the patient developed symptoms of nerve irritation, complained about neckache and headache and showed signs of agitation. The regimen was shifted to general anesthesia and surgery was performed. Because of postoperatively persistent headache and sensory disturbances an MRI scan of the lumbar spine was performed on the first postoperative day without pathological findings. The patient was able to leave the hospital after 1 week with significant relief of symptoms but 3 weeks later she developed neurocognitive impairment with memory deficits. A second MRI scan of the head now showed signs of disturbance of CSF circulation with hydrocephalus. Treatment was performed with drainage and ventriculoperitoneal shunt. Further evaluation showed a severe, multisegmental arachnoiditis and the patient developed a progressive paraparesis. The patient presented her case for assessment to a commission on medical malpractice 13 months after anesthesia. The commission detected no treatment errors. In connection to the case report a literature review of characteristics and etiologies of chronic adhesive arachnoiditis is given, which is a known but very rare complication of spinal anesthesia or similar procedures.

BACKGROUND: Impairments of social cognition are considered core features of schizophrenia and are established predictors of social functioning. However, affective aspects of social cognition including empathy have far less been studied than its cognitive dimensions. The role of empathy in the development of schizophrenia remains largely elusive. METHODS: Emotional and cognitive empathy were investigated in large sample of 120 individuals at Clinical High Risk of Psychosis (CHR-P) and compared with 50 patients with schizophrenia and 50 healthy controls. A behavioral empathy assessment, the Multifaceted Empathy Test, was implemented, and associations of empathy with cognition, social functioning, and symptoms were determined. RESULTS: Our findings demonstrated significant reductions of emotional empathy in individuals at CHR-P, while cognitive empathy appeared intact. Only individuals with schizophrenia showed significantly reduced scores of cognitive empathy compared to healthy controls and individuals at CHR-P. Individuals at CHR-P were characterized by significantly lower scores of emotional empathy and unspecific arousal for both positive and negative affective valences compared to matched healthy controls and patients with schizophrenia. Results also indicated a correlation of lower scores of emotional empathy and arousal with higher scores of prodromal symptoms. CONCLUSION: Findings suggest that the tendency to 'feel with' an interaction partner is reduced in individuals at CHR-P. Altered emotional reactivity may represent an additional, early vulnerability marker, even if cognitive mentalizing is grossly unimpaired in the prodromal stage. Different mechanisms might contribute to reductions of cognitive and emotional empathy in different stages of non-affective psychotic disorders and should be further explored.

In 1588 Sebastian Weiß, the son of a miller, became the first Lutheran pastor of Dittersbach in Saxony. At home he had repeatedly witnessed successful resuscitation of drowned persons by means of simple measures by his parents. Missing appropriate recommendations in the medical literature, in 1620 as "Sebastianus Albinus" he published a booklet with measures for reviving apparently drowned persons. This Kurtze Bericht und Handgrieff (Brief report and handgrip) attracted great attention amongst physicians, especially the reprint of 1675 of which a few copies still exist. The first printed edition from 1620 was lost until, some years ago, the apparently only still existing copy was rediscovered in the Herzog August Library in Wolfenbüttel.

OBJECTIVES: Tobacco use and alcohol use have their origin in adolescence, and risky use of these substances is amongst the leading preventable causes of morbidity and mortality. Health literacy (HL) encompasses the skills that are decisive to make appropriate health decisions in this context. Given the paucity of evidence on the link between HL and adolescents' health behaviors, the present study examined overall HL and different components of HL and their associations with smoking and alcohol use among 13 to 17-year-old Austrian students. STUDY DESIGN: Data were obtained from a national survey carried out in Austria (N = 4219; 56% females) as part of the Health Behaviour in School-aged Children: World Health Organization (WHO) collaborative cross-national study. METHODS: We tested two structural equation models, one including the overall HL scale as the predictor and one with the three subscales of HL 'finding,' 'understanding and appraising,' and 'applying' health-related information as predictors of smoking and alcohol use. RESULTS: Although overall HL was related to all indicators of adolescents' smoking and drinking, the three HL components had differential effects on these behaviors. The easier it was for the participants to 'understand and appraise' and 'apply' health-related information, the less frequently they had smoked and drunk alcohol and the less was the amount of alcohol they had consumed. Contrarily, the easier it was for the participants to 'find' information, the more they had smoked and drunk alcohol. CONCLUSIONS: Our results indicate that availability of health-related information may be insufficient on its own to prevent or reduce risky substance use. This is of particular importance for the development and improvement of primary prevention programs targeting adolescent populations.

Rayleigh-Taylor (RT) fluid turbulence through a bed of rigid, finite-size spheres is investigated by means of high-resolution direct numerical simulations, fully coupling the fluid and the solid phase via a state-of-the-art immersed boundary method. The porous character of the medium reveals a totally different physics for the mixing process when compared to the well-known phenomenology of classical RT mixing. For sufficiently small porosity, the growth rate of the mixing layer is linear in time (instead of quadratical) and the velocity fluctuations tend to saturate to a constant value (instead of linearly growing). We propose an effective continuum model to fully explain these results where porosity originated by the finite-size spheres is parametrized by a friction coefficient.
RESUMO
AIM: To determine the pathological features of colonic ischaemia (CI) and their relationship to symptom duration, disease distribution and clinical outcome in a real-world, clinical setting. METHOD: A retrospective, multicentre chart review was performed in patients diagnosed with CI at Montefiore Medical Center (January 2005 to July 2015), and Yale-New Haven Hospital (January 2005 to June 2010). Patients were included if clinical presentation, colonoscopic findings and colonic pathology were all consistent with CI. RESULTS: Six hundred and sixteen patients with pathologically proven CI were included. Common pathological findings included inflammation (51.1%), ulceration (38.2%), fibrosis (26.0%) and necrosis (20.4%). Infarction and ghost cells were seen in 1.6% and 0.2% of cases, respectively. There was a significant relationship between symptom duration and hyalinization of the lamina propria (P = 0.05) and cryptitis/crypt abscesses (P = 0.01). Patients with isolated right CI (IRCI) were more likely than patients with isolated left CI (ILCI) to exhibit necrosis (P < 0.01), cryptitis/crypt abscess (P < 0.01) and inflammation (P = 0.03). Patients with poor outcomes were more likely to exhibit necrosis (P < 0.01) and capillary fibrin thrombi (P < 0.01) and less likely to exhibit fibrosis (P < 0.01) and epithelial changes (P < 0.01). CONCLUSION: CI is accompanied by a broad spectrum of pathological findings. The traditional pathognomonic findings of CI are rare and cannot be relied upon to exclude the diagnosis. Patients with IRCI and/or poor outcomes were more likely to have pathological findings of necrosis than patients who had ILCI and/or nonpoor outcomes.

Isogenic wild type yeast cells raised in controlled environments display a significant range of lifespan variation. Recent microfluidic studies suggest that differential growth or gene expression patterns may explain some of the heterogeneity of aging assays. Herein, we sought to complement this work by similarly examining a large set of replicative lifespan data from traditional plate assays. In so doing, we reproduced the finding that short-lived cells tend to arrest at senescence with a budded morphology. Further, we found that wild type cells born unusually small did not have an extended lifespan. However, large birth size and/or high inter-generational growth rates significantly correlated with a reduced lifespan. Finally, we found that SIR2 expression levels correlated with lifespan and intergenerational growth. SIR2 expression was significantly reduced in large cells and increased in small wild type cells. A moderate increase in SIR2 expression correlated with reduced growth, decreased proliferation and increased lifespan in plate aging assays. We conclude that cellular growth rates and SIR2 expression levels may contribute to lifespan variation in individual cells.

For hundreds of years, bamboo has been employed for a variety of applications ranging from load-bearing structures to textiles. Thanks to its hierarchical structure that is functionally graded and naturally optimised, bamboo displays a variation in properties across its stem that ensures exceptional flexural performance. Often, alkaline solutions are employed for the treatment of bamboo in order to alter its natural elastic behaviour and make it suitable for particular applications. In this work we study the effect of NaOH solutions of five different concentrations (up to 25%) on the elastic properties of bamboo. By exploiting the capabilities of modern experimental techniques such as in situ synchrotron X-ray scattering and Digital Image Correlation, we present detailed analysis of the deformation mechanisms taking place in the main constituents of bamboo, i.e. fibres and matrix (Parenchyma). The principal achievement of this study is the elucidation of the deformation mechanisms at the fibre scale, where the relative sliding of fibrils plays a crucial role in the property modification of the whole bamboo stem. Furthermore, we shed light on the parenchyma toughness variation as a consequence of alkali treatments. STATEMENT OF SIGNIFICANCE: Alkaline solutions are often employed for the treatment of bamboo in order to alter its natural elastic behaviour. In this work we study the effect of alkaline solutions on the elastic properties of bamboo. Using state of the art experimental techniques allowed shedding light on the deformation mechanisms occurring in the bamboo main constituents, i.e. fibres and matrix (parenchyma cells). Enhancement of fibre stiffness was experienced when up to 20% NaOH solution was employed, while for higher concentration a decay was observed. This effect was imputed to the modification of adhesion between fibrils induced by disruption of ligand elements (e.g. lignin). Modification of the matrix toughness was also experienced, that indicated an improved resistance to cracking when the concentration of NaOH is 25%, while reduction of toughness was revealed for lower concentrations.

It remains unclear whether hepatitis B virus (HBV) infection may modify the severity of viral steatosis in patients coinfected with chronic hepatitis C virus (HCV). We examined the influence of coinfection with HBV on prevalence of steatosis in chronic hepatitis C in a multi-centre cohort of HBV-HCV subjects, and by performing a systematic review and meta-analysis of the literature. We centrally and blindly assessed steatosis prevalence and severity in a cohort of HBV-HCV coinfected subjects compared to HCV and HBV monoinfected controls and we performed a systematic review of studies addressing the prevalence of steatosis in HBV-HCV subjects compared to HCV controls. In the clinical cohort, we included 85 HBV-HCV, 69 HBV and 112 HCV subjects from 16 international centres. There was no significant difference in steatosis prevalence between the HBV-HCV and the HCV groups (33% vs 45%, P = .11). In subgroup analysis, lean HBV-HCV subjects with detectable HBV DNA had less steatosis than lean HCV subjects matched for HCV viremia (15% vs 45%, P = .02). Our literature search identified 5 additional studies included in a systematic review. Overall, prevalence of steatosis > 5% was similar in HBV-HCV infection compared to HCV (pooled odds ratio [OR] 0.91, 95% CI 0.53-1.6) although there was significant heterogeneity (I2 69%, P = .007). In conclusion, although the prevalence of steatosis is similar in HBV-HCV compared to HCV subjects, our analysis suggests that there may be an inhibitory effect of HCV-induced steatogenesis by HBV in certain subgroups of patients.

Trivalent lanthanides provide stable emission sources at wavelengths spanning the ultraviolet through the near infrared with uses in telecommunications, lighting, and biological sensing and imaging. We describe a method for incorporating an organometallic lanthanide complex within polyelectrolyte multilayers, producing uniform, optically active thin films on a variety of substrates. These films demonstrate excellent emission with narrow linewidths, stable over a period of months, even when bound to metal substrates. Utilizing different lanthanides such as europium and terbium, we are able to easily tune the resulting wavelength of emission of the thin film. These results demonstrate the suitability of this platform as a thin film emitter source for a variety of photonic applications such as waveguides, optical cavities, and sensors.
RESUMO
BACKGROUND: Allergic reactions to the common house plant Hoya compacta (HC) have not previously been described. AIMS: To confirm HC as the cause of rhinoconjunctivitis in three horticultural workers. METHODS: Greenhouse working conditions were reproduced in our challenge chamber. RESULTS: All three cases developed rhinoconjunctivitis when working with HC plants. A control challenge was performed in two cases with iceberg lettuce causing no symptoms. Nasal volume measured by acoustic rhinometry (AR) fell after all three active challenges, but also after one of the control challenges. CONCLUSIONS: Our study confirms that HC may cause occupational rhinoconjunctivitis and asthma through a Type I hypersensitivity reaction. Specific inhalation challenges, nasal nitric oxide measurement and AR may be useful additional tools in supporting such diagnoses for occupational physicians to consider.

The surgeon Hans Killian was born on 5 August 1892 in Freiburg im Breisgau, Germany. Together with the pharmacologist Hellmut Weese and the surgeon Helmut Schmidt he was one of the nestors of modern German anesthesia. Early on during his scientific and clinical career, he addressed problems of surgical anesthesia and in 1928 he became one of the editors of the first German journal of anesthesia Narcosis and Anesthesia ("Narkose und Anästhesie"). In 1934 he published the textbook Anesthesia for Surgical Purposes ("Narkose zu operativen Zwecken"). Between World Wars I and II, he campaigned for anesthesia to become an independent medical discipline comparable to the situation in the Anglo-Saxon countries at that time. Because of his merits in the foundation of the German Society of Anesthesia on 10 April 1953 he became its first honorary member. Killian died on 7 March 1982 in Freiburg, Germany. Excerpts of his autobiography which he wrote a few years before his death and which were part of his inheritance are published here for the first time.

OBJECTIVE: There is some evidence that clozapine is significantly underutilised. Also, clozapine use is thought to vary by country, but so far no international study has assessed trends in clozapine prescribing. Therefore, this study aimed to assess clozapine use trends on an international scale, using standardised criteria for data analysis. METHOD: A repeated cross-sectional design was applied to data extracts (2005-2014) from 17 countries worldwide. RESULTS: In 2014, overall clozapine use prevalence was greatest in Finland (189.2/100 000 persons) and in New Zealand (116.3/100 000), and lowest in the Japanese cohort (0.6/100 000), and in the privately insured US cohort (14.0/100 000). From 2005 to 2014, clozapine use increased in almost all studied countries (relative increase: 7.8-197.2%). In most countries, clozapine use was highest in 40-59-year-olds (range: 0.6/100 000 (Japan) to 344.8/100 000 (Finland)). In youths (10-19 years), clozapine use was highest in Finland (24.7/100 000) and in the publicly insured US cohort (15.5/100 000). CONCLUSION: While clozapine use has increased in most studied countries over recent years, clozapine is still underutilised in many countries, with clozapine utilisation patterns differing significantly between countries. Future research should address the implementation of interventions designed to facilitate increased clozapine utilisation.

The budding yeast Saccharomyces cerevisiae and fission yeast Schizosaccharomyces pombe are amongst the simplest and most powerful model systems for studying the genetics of cell cycle control. Because yeast grows very rapidly in a simple and economical media, large numbers of cells can easily be obtained for genetic, molecular, and biochemical studies of the cell cycle. The use of synchronized cultures greatly aids in the ease and interpretation of cell cycle studies. In principle, there are two general methods for obtaining synchronized yeast populations. Block-and-release methods can be used to induce cell cycle synchrony. Alternatively, centrifugal elutriation can be used to select synchronous populations. Because each method has innate advantages and disadvantages, the use of multiple approaches helps in generalizing results. An overview of the most commonly used methods to generate synchronized yeast cultures is presented along with working Notes: a section that includes practical comments, experimental considerations and observations, and hints regarding the pros and cons innate to each approach.

UNLABELLED: The presence of an intrahepatic cholangiocarcinoma (iCCA) in a cirrhotic liver is a contraindication for liver transplantation in most centers worldwide. Recent investigations have shown that "very early" iCCA (single tumors ≤2 cm) may have acceptable results after liver transplantation. This study further evaluates this finding in a larger international multicenter cohort. The study group was composed of those patients who were transplanted for hepatocellular carcinoma or decompensated cirrhosis and found to have an iCCA at explant pathology. Patients were divided into those with "very early" iCCA and those with "advanced" disease (single tumor >2 cm or multifocal disease). Between January 2000 and December 2013, 81 patients were found to have an iCCA at explant; 33 had separate nodules of iCCA and hepatocellular carcinoma, and 48 had only iCCA (study group). Within the study group, 15/48 (31%) constituted the "very early" iCCA group and 33/48 (69%) the "advanced" group. There were no significant differences between groups in preoperative characteristics. At explant, the median size of the largest tumor was larger in the "advanced" group (3.1 [2.5-4.4] versus 1.6 [1.5-1.8]). After a median follow-up of 35 (13.5-76.4) months, the 1-year, 3-year, and 5-year cumulative risks of recurrence were, respectively, 7%, 18%, and 18% in the very early iCCA group versus 30%, 47%, and 61% in the advanced iCCA group, P = 0.01. The 1-year, 3-year, and 5-year actuarial survival rates were, respectively, 93%, 84%, and 65% in the very early iCCA group versus 79%, 50%, and 45% in the advanced iCCA group, P = 0.02. CONCLUSION: Patients with cirrhosis and very early iCCA may become candidates for liver transplantation; a prospective multicenter clinical trial is needed to further confirm these results.

OBJECTIVES: In adults, impaired fasting glycemia (IFG) increases the risk for type 2 diabetes mellitus (T2DM). This study aimed to investigate to which extent children with obesity develop T2DM during early adulthood, and to determine whether IFG and elevated hemoglobin A1c (HbA1c) in obese children are risk markers for early development of T2DM. METHODS: In this prospective cohort study, 1620 subjects from the Swedish Childhood Obesity Treatment Registry - BORIS who were ⩾18 years at follow-up and 8046 individuals in a population-based comparison group, matched on gender age and living area, were included. IFG was defined according to both ADA (cut-off 5.6 mmol l(-1)) and WHO (6.1 mmol l(-1)). Elevated HbA1c was defined according to ADA (cut-off 39 mmol l(-1)). Main outcome was T2DM medication, as a proxy for T2DM. Data on medications were retrieved from a national registry. RESULTS: The childhood obesity cohort were 24 times more likely to receive T2DM medications in early adulthood compared with the comparison group (95% confidence interval (CI): 12.52-46). WHO-defined IFG predicted future use of T2DM medication with an adjusted hazard ratio (HR) of 3.73 (95% CI: 1.87-7.45) compared with those who had fasting glucose levels <5.6 mmol l(-1). A fasting glucose level of 5.6-6.0 mmol l(-1), that is, the IFG-interval added by American Diabetes Association (ADA), did not increase the use of T2DM medication more than pediatric obesity itself, adjusted HR=1.72 (0.84-3.52). Elevated levels of HbA1c resulted in an adjusted HR=3.12 (1.50-6.52). More severe degree of obesity also increased the future T2DM risk. CONCLUSION: IFG according to WHO and elevated HbA1c (39-48 mmol l(-1)), but not the additional fasting glucose interval added by ADA (5.6-6.0 mmol l(-1)), can be considered as prediabetes in the obese pediatric population in Sweden.
