Among older patients undergoing hip fracture surgery, previous studies have shown a seasonal variation of in-hospital surgical complications. However, little is known about seasonal effects on mortality and systemic complications after hip fracture surgery. In the present study, we evaluated whether mortality and in-hospital systemic complications are influenced by seasonal differences.

We enrolled patients from a nationwide database who underwent hip fracture surgery between 2010 and 2018. The primary outcome was in-hospital mortality. The secondary outcomes were in-hospital systemic complications. The association between the seasonality and in-hospital outcomes was investigated using multivariable Cox, logistic regression and causal mediation analysis.

With 425 856 patients (mean age 83.5 years; 79% women), overall in-hospital mortality was 5324 (1.2%). Fall and winter were associated with a higher mortality than spring (hazard ratio [HR] 1.16; P < 0.001; HR 1.14; P = 0.001, respectively). Across all the seasons, there were 36 834 overall systemic complications (8.6%), with respiratory infection being the most frequent (18 637 [4.4%]). Among these complications, only respiratory infection showed seasonal variation, with a higher prevalence in fall and winter. The mediated effect of respiratory infection on mortality was significantly higher in fall and winter compared with spring (fall, HR 1.06, proportion mediated 36.7%; winter, HR 1.14, proportion mediated 55.0%; all P < 0.001).

We found a significantly higher mortality in fall and winter after hip fracture surgery. Specifically, in winter, the increased in-hospital death was largely attributed to the increased incidence of respiratory infection. Geriatr Gerontol Int 2021; 21 398-403.

Therefore, it is challenging to study the dedicated temperature signalling pathways that orchestrate thermomorphogenesis, a suite of elongation growth-based adaptations that enhance leaf-cooling capacity. We screened a chemical library for compounds that restored hypocotyl elongation in the pif4-2-deficient mutant background at warm temperature conditions in Arabidopsis thaliana to identify modulators of thermomorphogenesis. The small aromatic compound 'Heatin', containing 1-iminomethyl-2-naphthol as a pharmacophore, was selected as an enhancer of elongation growth. We show that ARABIDOPSIS ALDEHYDE OXIDASES redundantly contribute to Heatin-mediated hypocotyl elongation. Following a chemical proteomics approach, the members of the NITRILASE1-subfamily of auxin biosynthesis enzymes were identified among the molecular targets of Heatin. Our data reveal that nitrilases are involved in promotion of hypocotyl elongation in response to high temperature and Heatin-mediated hypocotyl elongation requires the NITRILASE1-subfamily members, NIT1 and NIT2. Heatin inhibits NIT1-subfamily enzymatic activity in vitro and the application of Heatin accordingly results in the accumulation of NIT1-subfamily substrate indole-3-acetonitrile in vivo. However, levels of the NIT1-subfamily product, bioactive auxin (indole-3-acetic acid), were also significantly increased. It is likely that the stimulation of hypocotyl elongation by Heatin might be independent of its observed interaction with NITRILASE1-subfamily members. However, nitrilases may contribute to the Heatin response by stimulating indole-3-acetic acid biosynthesis in an indirect way. Danicamtiv Heatin and its functional analogues present novel chemical entities for studying auxin biology.

Despite international recommendations, less than one-third of Australian women exclusively breastfeed for 6 months. The aims of this study were to prospectively determine rates and factors associated with the type and duration of breastfeeding in the first year and examine the effect of minimal supplementation.

We conducted a sub-study of a randomised controlled trial in Sydney, Australia, which included 635 women with uncomplicated term births who intended to breastfeed. Data were collected daily for 56 days, and then at 2, 6 and 12 months post-partum.

Breastfeeding outcomes were evaluated for 553 (87%), 480 (76%) and 392 (62%) women at 2, 6 and 12 months. Exclusive breastfeeding was 81% at 2 months and 8% at 6 months. Partial breastfeeding was 75% at 6 months and 54% at 12 months. Factors associated with breastfeeding cessation included caesarean birth, low milk supply, problems latching, increased time to breastfeed, use of formula >7 days in the first 2 months, return to work and early introductiy leave and workplace incentives could be effective in prolonging breastfeeding.Macrophages exhibit distinct phenotypes in response to environmental signals. The polarization of M1 macrophages plays an essential role in the inflammatory response. However, the specific molecular mechanisms regulating the inflammatory response during M1 macrophage polarization remain to be further understood. Here, we found that the histone acetyltransferase P300/CBP-associated factor (PCAF) was a potential negative regulator of the M1 macrophage inflammatory response. During M1 macrophage polarization, the inflammatory response gradually reduced, but PCAF expression increased. Furthermore, the overexpression of PCAF significantly inhibited the expression of the M1 macrophage-related pro-inflammatory genes TNF-α, IL-6 and CXCL10, while PCAF deficiency enhanced the expression of these genes. Furthermore, we found that PCAF overexpression suppressed the NF-κB signaling pathway and promoted the expression of the Krüppel-like factors (KLF) KLF2 and KLF4 through regulating their transcriptional levels. In addition, KLF2 and KLF4 deficiency reversed the PCAF-induced inhibition of the expression of pro-inflammatory genes in M1 macrophages. Collectively, the present results demonstrate a potential negative regulatory mechanism of the inflammatory response during M1 macrophage polarization and propose a novel mechanism of inflammation resolution for maintaining homeostasis.

Skin protection products, formerly named as barrier creams, are being used as primary and secondary prevention measures against occupational dermatoses. Many of these cosmetic products are claimed by manufacturers to be efficacious against wet work-induced skin barrier impairment if applied prior to exposure. However, results of validated and standardized in vivo efficacy tests allowing the comparison of different products are lacking.

Efficacy of six skin protection products against sodium lauryl sulphate-induced irritant contact dermatitis was investigated in a double blind, randomized and controlled repetitive irritation study in healthy volunteers using skin physiological methods. Transepidermal water loss (TEWL) results were used to calculate an efficacy index of protection by mathematical/statistical means according to a protocol developed in a German Statutory Accident Insurance (DGUV) multicenter study (research project FP 275).

All tested products had a demonstrable, protective effect against SLS compared to controls, but their relative efficacy varied significantly. Differences were also seen upon evaluation of other parameters such as corneometry and clinical irritation score (visual score).

Product ranking as a result of the established differences allows improved selection of appropriate skin protection products based on objective parameters, as compared to heterogenous product claims.

Since 1936, the medical-objective obligation to refrain from risky work activities, which has been necessary for the recognition of this occupational disease, was intended to delimit trivial diseases, facilitate the determination of occupational causality and promote prevention. The abolition of the legal obligation to refrain from risky work activities as a criterion for the recognition of the occupational disease 5101 as of 01.01.2021 has significant effects on the occupational dermatological care and expert assessment of this occupational disease. For less severe occupational skin diseases, however, the preventive dermatologist's procedure established since 1972 will continue to apply.Biomarker signatures identified through minimally invasive procedures already at diagnosis of non-small-cell lung cancer (NSCLC) could help to guide treatment with immune checkpoint inhibitors (ICI). Here, we performed multiplex profiling of immune-related proteins in fine-needle aspirate (FNA) samples of thoracic lesions from patients with NSCLC to assess PD-L1 expression and identify related protein signatures. Transthoracic FNA samples from 14 patients were subjected to multiplex antibody-based profiling by proximity extension assay (PEA). PEA profiling employed protein panels relevant to immune and tumor signaling and was followed by Qlucore® Omics Explorer analysis. All lesions analyzed were NSCLC adenocarcinomas, and PEA profiles could be used to monitor 163 proteins in all but one sample. Multiple key immune signaling components (including CD73, granzyme A, and chemokines CCL3 and CCL23) were identified and expression of several of these proteins (e.g., CCL3 and CCL23) correlated to PD-L1 expression. We also found EphA2, a marker previously linked to inferior NSCLC prognosis, to correlate to PD-L1 expression. Our identified protein signatures related to stage included, among others, CXCL10 and IL12RB1. We conclude that transthoracic FNA allows for extensive immune and tumor protein profiling with assessment of putative biomarkers of important for ICI treatment selection in NSCLC.Cardiac hemangiomas are rare entities and very few cases have been reported where they originate from the main arteries of the heart. We present a case of hemangioma arising from the main pulmonary artery, which was completely resected with clear margins on the beating heart.

Evidence-based treatments in routine clinical practice often fail to achieve or sustain amelioration of severe behaviour problems in adolescents. Better understanding of mechanisms underlying such severe behaviour problems could improve treatments. Underlying schemata and schema modes may play an important role.

To compare early maladaptive schemata, schema modes and behaviour problems in adolescent boys showing disruptive and offending behaviours with those in typically developing boys. We hypothesised a relationship between disconnection and rejection schemata on the one hand and behaviour problems (including offending) on the other in adolescent boys with disruptive behaviour disorders. We also hypothesised that this offending group would differ significantly from typically developing boys on these measures and that schema modes would mediate relationships between schemata and overt behaviours.

In this cross-sectional study, fifty-five 12-19-year-old boys with disruptive behaviour disorders referred to an in- or out-patient clinic were matched to fifty-five typically developing boys from a previously generated school sample.
