We would like to thank to Dr Ludvigsson (1), who was the only critical commentary author to acknowledge the methodological problems inherent in the diagnosis of shaken baby syndrome, following the publication of our systematic review (2) in Acta Paediatrica. Dr Ludvigsson posed two questions regarding the two main conclusions, which deserve responses. This article is protected by copyright. All rights reserved.

Narang et al (1) maintain that the research question in our systematic review in Acta Paediatrica (2) was based on the findings of Guthkelch in 1971 (3), and that we presumed that Guthkelch introduced the shaken baby syndrome triad. That is not correct. We used the Guthkelch example in the introduction in order to illustrate when the discussion on shaken baby syndrome was initiated. As our research question was a reverse causality version of the Guthkelch hypothesis, it was not influenced by that hypothesis...

Complex glenoid deformities present the most difficult challenges in shoulder arthroplasty. These deformities may be caused by severe degenerative or congenital deformity, posttraumatic anatomy, tumor, or, in most cases, bone loss after glenoid failure in anatomical total shoulder arthroplasty. Methods of treating severe bone loss have included inlay and onlay bone-graft options with augmented fixation and, in severe cases, salvage hemiarthroplasty with limited goal expectations. Unfortunately, none of these methods has provided consistently satisfactory reproducible results...

A novel organocatalyzed direct aldol reaction of aldehydes to silyl glyoxylates is disclosed. This method provides an efficient route to α-hydroxysilanes with excellent enantioselectivities (up to 99% ee) and high diastereoselectivities (up to >20:1 dr). In the new activation model of silyl glyoxylates, the hydrogen bond is critical to the reaction. A carbonyl group directly attached to silicon in acylsilanes could be activated by coordination to the proton of hydroxyl and carboxylic acid via a hydrogen bond...

A novel approach to regioselectively substituted and stereoselectively α-trifluoromethylated tryptamines is reported based on the ene reaction of Boc-protected 3-methyleneindolines with optically pure (R)- or (S)-tert-butanesulfinyltrifluoroacetaldimine. Boc- and sulfinylamido-protected α-trifluoromethyltryptamines are obtained in 60-70% yield and 85/15 dr by just heating equimolar amounts of the two reaction partners at 80-90 °C for 2-3 h without a solvent. The absolute configuration of the amino α-carbon has been assigned based on the vibrational circular dichroism (VCD) spectral analysis...

Propensity score based statistical methods, such as matching, regression, stratification, inverse probability weighting (IPW), and doubly robust (DR) estimating equations, have become popular in estimating average treatment effect (ATE) and average treatment effect among treated (ATT) in observational studies. Propensity score is the conditional probability receiving a treatment assignment with given covariates, and propensity score is usually estimated by logistic regression. However, a misspecification of the propensity score model may result in biased estimates for ATT and ATE...

In the spirit of Dr. Haggerty's teachings, we present an overview of our work to improve care for children with asthma in the context of 3 lessons learned:(1) 1) The importance of providing integrated services across disciplinary boundaries for children with chronic illness, 2) The need to move from a care model focused only on the individual child to a model focused on the child, family, and community, and 3) The need to expand beyond the local community and take a broad perspective on improving health on a national level...

The common knowledge of a uniqueness of REM sleep as a privileged scenario of dreaming still persists, although consolidated empirical evidence shows that the assumption that dreaming is just an epiphenomenon of REM sleep is no longer tenable. However, the brain mechanisms underlying dream generation and its encoding in memory during NREM sleep are still mostly unknown. In fact, only few studies have investigated on the mechanisms of dream phenomenology related to NREM sleep. For this reason, our study is specifically aimed to elucidate the electrophysiological (EEG) correlates of dream recall (DR) upon NREM sleep awakenings...

REVIEW
Aimée Parker, Jim Kaufman
Almost all knowledge about the structure and function of MHC class II molecules outside of mammals comes from work with chickens. Most of the genes implicated in the class II system are present in chickens, so it is likely that the machinery of antigen processing and peptide-loading is similar to mammals. However, there is only one isotype (lineage) of classical class II genes, with one monomorphic DR-like BLA gene and two polymorphic BLB genes, located near one DMA and two DMB genes. The DMB2 and BLB2 genes are widely expressed at high levels, whereas the DMB1 and BLB1 genes are only expressed at highest levels in spleen and intestine, suggesting the possibility of two class II systems in chickens...

Diabetes duration, diabetic retinopathy (DR), and a diagnostic model have been proposed as clinical parameters favoring the presence of diabetic nephropathy (DN) in biopsied patients with diabetic kidney disease. DN, compared with non-diabetic renal disease, had poorer renal outcomes. We tested whether these clinical parameters favoring DN are associated with poorer renal outcomes in non-biopsied patients. In this study, 1330 patients with type 2 diabetes and chronic kidney disease stages 1-4 were included and divided according to diabetes mellitus (DM) duration >8 years, DR, or a diagnostic model for DN...

Natural killer (NK) cells have therapeutic potential for cancer due to their capacity for targeting tumor cells without prior sensitization. Our laboratory has developed an NK cell expansion protocol that generates large quantities of NK cells for therapeutic infusion that secret 20 times the amount of interferon gamma (IFNγ) than resting NK cells. IFNγ can upregulate major histocompatibility complex (MHC)-class I, an inhibitory ligand for NK cells, but can also upregulate intercellular adhesion molecule 1 (ICAM-1) which promotes NK:target cell interaction for an efficient lysis...

Rapid eye movement sleep (REMS) plays important role in maintenance of normal brain functions. Neurons containing various neurotransmitters in different brain regions interact to regulate this complex phenomenon in health and diseases. The number of neuronal projections, their firing rates and neurotransmitter levels vary in different brain regions under various conditions leading to normal or altered patho-physio-behavioral states. In this study using high performance liquid chromatography (HPLC) we quantified noradrenaline (NA) and gamma-amino butyric acid (GABA) levels in locus coeruleus (LC), dorsal raphe (DR), pedunculo-pontine tegmentum (PPT), frontal lobe (FL), cortex and hippocampus (Hippo) in control and after 96 h REMS deprivation (REMSD) rats...

Technical advancements have substantially extended the indications for surgery in diabetic retinopathy (DR) during the last 40 years, from the traditional indications including non-clearing vitreous hemorrhage, traction retinal detachment (RD), and traction-rhegmatogenous RD, to epiretinal membrane (ERM), vitreomacular traction, diffuse macular edema, neovascular glaucoma, and anterior hyaloid fibrovascular proliferation. The goals of vitreoretinal surgery in DR are multiple: clearing media opacities, release of traction (anteroposterior and/or tangential), segmentation and/or removal of traction bands, peeling of ERMs, hemostasis, laser photocoagulation, and tamponade of retinal breaks with gas or silicone oil...

Diabetic retinopathy (DR), a major microvascular complication of diabetes, has a significant impact on the world's health systems. Globally, the number of people with DR will grow from 126.6 million in 2010 to 191.0 million by 2030, and it is estimated that the number with vision-threatening diabetic retinopathy will increase from 37.3 million to 56.3 million if prompt action is not taken. Lack of early diagnosis and management is the leading cause of blindness in working-age populations The gap between demand and annual eye examinations has been a big challenge...
