All-cause mortality in males with sleep apnoea syndrome: declining mortality rates with age

The objective of this study was to assess whether an increasing severity of sleep apnoea is associated with increased all-cause mortality hazards and to assess whether the syndrome is associated with excess mortality, in comparison with the general population. Participants included 14,589 adult males, aged 20–93 yrs, referred to the sleep clinics with suspected sleep apnoea or diagnosed with sleep apnoea. Altogether, 372 deaths were recorded after a median follow-up of 4.6 yrs. The crude all-cause mortality rate was 5.55/1,000 patient yrs, increasing with apnoea severity. Cox proportional analysis revealed that both respiratory disturbance index (RDI) and body mass index significantly influenced all-cause mortality hazard but there was no interaction between them. Males with respiratory disturbance index >30 had a significantly higher mortality hazard rate than the reference group of males with RDI ≤10. Comparing mortality rates of males with moderate/severe sleep apnoea to the general population revealed that only males aged <50 yrs showed an excess mortality rate. The hazard of mortality in sleep apnoea increases with apnoea severity as indexed by respiratory disturbance index. Moderate and severe levels of sleep apnoea are moderately associated with an increased risk of all-cause mortality, in comparison with the general population, particularly in males aged <50 yrs. The lack of information about possible confounders and treatment effects should be taken into consideration in the interpretation of these results.
Down with odds ratios!

As described in an earlier EBM note (1) and in our glossary, this journal reports the results of individual randomised trials in terms of relative risk reductions (RRRs), calculated by dividing the absolute difference in event rates between the control (control event rate [CER]) and experimental (experimental event rate [EER]) patients by the event rate for the controls: (CER – EER)/CER = RRR. From these same values, we also report the number of patients that would need to be treated (NNT) to prevent 1 additional event—1/(CER–EER)—or by its alternative calculation–1/(RRR × CER). Thus, in the example shown in Table 1, the RRR is 89% and the NNT is 4 (2).

The efficacy of cold-gel packing for relieving episiotomy pain – a quasi-randomised control trial

Purposes: This study evaluated the effectiveness of cold-gel packing on episiotomy pain among postpartum women who had normal spontaneous deliveries. Methods: A quasi-randomised control trial was conducted in a maternity ward of a regional teaching hospital in northern Taiwan. Seventy postpartum women were recruited, choosing to be in either the experimental or control group (35 women per group). Subjects in the experimental group received at least six interventions of cold-gel packing applied to the perineal wound and were provided oral analgesics routinely. The subjects in the control group received oral analgesics routinely. Findings: Pain intensity, pain interference on daily activities and satisfaction levels with pain management were assessed using Brief Pain Inventory (BPI) and pain management questionnaire, respectively. The results showed that women in the experimental group reported significantly lower mean pain intensity score, pain interference on daily activities scores at 48 hours post-delivery, and higher level of satisfaction with pain management at 24 and 48 hours post-delivery than the control group after adjusting for demographic and obstetric data. Conclusions: Cold-gel packing on the perineum is a cost-effective, convenient, easy-to-deploy and non-pharmacologic approach to pain reduction, with an overall positive impact on postpartum recovery for parturients.
Scaling of xylem and phloem transport capacity and resource usage with tree size

Xylem and phloem need to maintain steady transport rates of water and carbohydrates to match the exchange rates of these compounds at the leaves. A major proportion of the carbon and nitrogen assimilated by a tree is allocated to the construction and maintenance of the xylem and phloem long distance transport tissues. This proportion can be expected to increase with increasing tree size due to the growing transport distances between the assimilating tissues, i.e., leaves and fine roots, at the expense of their growth. We formulated whole tree level scaling relations to estimate how xylem and phloem volume, nitrogen content and hydraulic conductance scale with tree size, and how these properties are distributed along a tree height. Xylem and phloem thicknesses and nitrogen contents were measured within varying positions in four tree species from Southern Finland. Phloem volume, nitrogen amount and hydraulic conductance were found to be concentrated toward the branch and stem apices, in contrast to the xylem where these properties were more concentrated toward the tree base. All of the species under study demonstrated very similar trends. Total nitrogen amount allocated to xylem and phloem was predicted to be comparable to the nitrogen amount allocated to the leaves in small and medium size trees, and to increase significantly above the nitrogen content of the leaves in larger trees. Total volume, hydraulic conductance and nitrogen content of the xylem were predicted to increase faster than that of the phloem with increasing tree height in small trees (<~10 m in height). In larger trees, xylem sapwood turnover to heartwood, if present, would maintain phloem conductance at the same level with xylem conductance with further increases in tree height. Further simulations with a previously published xylem-phloem transport model demonstrated that the Münch pressure flow hypothesis could explain phloem transport with increasing tree height even for the tallest trees.
Health and Quality of Life Outcomes

Background: Quality of life (QoL) outcomes are useful in the assessment of physical, mental and social well-being and for informed healthcare decision making. However, few studies have evaluated QoL issues among Asian children due largely to the lack of culturally valid and reliable QoL questionnaires. Hence, we aimed to report the psychometric properties, in particular factor structure, of KINDL (Singapore) questionnaires among school-going children. Methods: Students aged 8–16 years from participating schools were selected by convenience sampling. Subjects self-completed KINDL-Kid (Singapore) and KINDL-Kiddo (Singapore) questionnaires, which were cross-culturally adapted from KINDL (Germany English) for use in Singapore. We evaluated floor and ceiling effects, internal consistency and performed factor analysis. Results: A total of 328 respondents (mean (SD) age: 9.6 (1.31) years; 67% female; 75% Chinese, 16% Malays, 9% Indians and others) completed KINDL-Kid while 1,026 respondents (mean (SD) age: 14.0 (1.00) years; 82% female; 82% Chinese, 12% Malays; 6% Indians and others) completed KINDL-Kiddo. Mean (SD) TOTAL QoL score was 65.5 (12.76) and 56.6 (11.92) for KINDL-Kid and KINDL-Kiddo, respectively. Floor and ceiling effects were important in five of six KINDL-Kid and two of six KINDL-Kiddo subscales. Reliability coefficients ranged from 0.40 to 0.71 (KINDLKid) and 0.44 to 0.84 (KINDL-Kiddo). Factor analysis generated eight and seven factors in KINDLKid and KINDL-Kiddo, respectively. Conclusion: KINDL-Kiddo exhibited good psychometric properties and may be used to assess QoL in this multi-ethnic English-speaking Asian population. However, psychometric properties of KINDL-Kid may need to be improved either by developing new items or modifying existing items. Background Worldwide, there is an increasing interest in the measurement of quality of life (QoL) outcomes, which are useful in the assessment of physical, mental and social wellPublished: 19 January 2007 Health and Quality of Life Outcomes 2007, 5:4 doi:10.1186/1477-7525-5-4 Received: 27 September 2006 Accepted: 19 January 2007 This article is available from: http://www.hqlo. com/content/5/1/4 © 2007 Wee et al; licensee BioMed Central Ltd.

Affective states leak into movement execution: Automatic avoidance of threatening stimuli in fear of spider is visible in reach trajectories

Approach-like actions are initiated faster with stimuli of positive valence. Conversely, avoidance-like actions are initiated faster with threatening stimuli of negative valence. We went beyond reaction time measures and investigated whether threatening stimuli also affect the way in which an action is carried out. Participants moved their hand either away from the picture of a spider (avoidance) or they moved their hand toward the picture of a spider (approach). We compared spider-fearful participants to non-anxious participants. When reaching away from the threatening spider picture, spider-fearful participants moved more directly to the target than controls. When reaching toward the threatening spider, spider-fearful participants moved less directly to the target than controls. Some conditions that showed clear differences in movement trajectories between spider-fearful and control participants were devoid of differences in reaction time. The deviation away from threatening stimuli provides evidence for the claim that affective states like fear leak into movement programming and produce deviations away from threatening stimuli in movement execution. Avoidance of threatening stimuli is rapidly integrated into ongoing motor behaviour in order to increase the distance between the participant's body and the threatening stimulus.
Resilience and Depressive Symptoms in Midlife Women

RESILIENCE AND DEPRESSIVE SYMPTOMS IN MIDLIFE WOMEN By Keveme L. Lehman Rates of depression are increasing throughout the world, with women experiencing depression twice as often as men. This study utilized the Neuman Systems Model to examine the relationship in midlife women between depressive symptoms and resilience. Women ages 35-55, selected from four health care settings, completed written surveys on demographic information, life events, depression, and resilience. Results supported depressive symptoms as a health concern for mid-life women: 32% reporting current or previous treatment for depression, and 24% screening positive for depression. Resilience, measured by the Polk Resilience Patterns Scale, was related to education, perceived health, conflict in the living situation, and financial resources. It was inversely correlated with depressive symptoms. Depressive symptoms were related to perceived health, conflict in the living situation, financial resources, and sleep. Negative life events and the situational and philosophical resilience subscales contributed to 64% of the variance in the measure of depressive symptoms.

Are Modular Activations Altered in Lower Limb Muscles of Persons with Multiple Sclerosis during Walking? Evidence from Muscle Synergies and Biomechanical Analysis

Background: Persons with Multiple Sclerosis frequently have gait deficits that lead to diminished activities of daily living. Identification of motoneuron activity patterns may elucidate new insight into impaired locomotor coordination and underlying neural systems. The aim of the present study was to investigate muscle synergies, identified by motor modules and their activation profiles, in persons with Multiple Sclerosis (PwMS) during walking compared to those of healthy subjects (HS), as well as, exploring relationship of muscle synergies with walking ability of PwMS. Methods: Seventeen PwMS walked at their natural speed while 12 HS walked at slower than their natural speeds in order to provide normative gait values at matched speeds (spatio-temporal, kinematic, and kinetic parameters and electromyography signals). Non-negative matrix factorization was used to identify muscle synergies from eight muscles. Pearson's correlation coefficient was used to evaluate the similarity of motor modules between PwMS and HS. To assess differences in module activations, each module's activation timing was integrated over 100% of gait cycle and the activation percentage was computed in six phases. Results: Fifty-nine% of PwMS and 58% of HS had 4 modules while the remaining of both populations had 3 modules. Module 2 (related to soleus, medial, and lateral gastrocnemius primarily involved in mid and terminal stance) and Module 3 (related to tibialis anterior and rectus femoris primarily involved in early stance, and early and late swing) were comparable across all subjects regardless of synergies number. PwMS had shorter stride length, longer double support phase and push off deficit with respect to HS (p < 0.05). The alterations of activation timing profiles of specific modules in PwMS were associated with their walking deficits (e.g., the reduction of Module 2 activation percentage index in terminal stance, PwMS 35.55 ± 13.23 vs. HS 50.51 ± 9.13% p < 0.05, and the push off deficit, PwMS 0.181 ± 0.136 vs. HS 0.291 ± 0.062 w/kg p < 0.05). Conclusion: During gait PwMS have synergies numbers similar to healthy persons. Their neurological deficit alters modular control through modifications of the timing activation profiles rather than module composition. These changes were associated with their main walking impairment, muscle weakness, and prolonged double support.
Essential Functions of the Unique N-Terminal Region of the Varicella-Zoster Virus Glycoprotein E Ectodomain in Viral Replication and in the Pathogenesis of Skin Infection

ABSTRACT Varicella-zoster virus (VZV) glycoprotein E (gE) is a multifunctional protein important for cell-cell spread, envelopment, and possibly entry. In contrast to other alphaherpesviruses, gE is essential for VZV replication. Interestingly, the N-terminal region of gE, comprised of amino acids 1 to 188, was shown not to be conserved in the other alphaherpesviruses by bioinformatics analysis. Mutational analysis was performed to investigate the functions associated with this unique gE N-terminal region. Linker insertions, serine-to-alanine mutations, and deletions were introduced in the gE N-terminal region in the VZV genome, and the effects of these mutations on virus replication and cell-cell spread, gE trafficking and localization, virion formation, and replication in vivo in the skin were analyzed. In summary, mutagenesis of the gE N-terminal region identified a new functional region in the VZV gE ectodomain essential for cell-cell spread and the pathogenesis of VZV skin tropism and demonstrated that different subdomains of the unique N-terminal region had specific roles in viral replication, cell-cell spread, and secondary envelopment.
The pineal secretory product melatonin reduces hydrogen peroxide‐induced DNA damage in U‐937 cells

Abstract: Melatonin, the chief secretory product of the pineal gland, is a potent and efficient endogenous radical scavenger. Thus, melatonin was shown to protect different biomolecules, such as DNA, membrane lipids, and cytosolic proteins, from oxidative damage induced by oxygen‐derived free radicals. In order to study the protective role of melatonin in hydrogen peroxide (H2O2)‐induced DNA damage, U‐937 cells were treated with different concentrations of H2O2, either in the presence or absence of melatonin, and DNA damage was assessed using the cytokinesis‐block micronucleus technique. Melatonin diminished H2O2‐induced micronuclei production both in short and long treatments. Additionally, melatonin concentrations higher than 1 μM were capable of protecting cells from spontaneous micronuclei production. These data suggest that melatonin, an endogenous antioxidant and nontoxic compound, may have an important role in protecting cells from genetic damage due to free radicals, supporting the idea of this hormone as a possible therapeutic agent in preventing aging and age‐related diseases.
Dual HER2 Targeting Impedes Growth of HER2 Gene–Amplified Uterine Serous Carcinoma Xenografts

Purpose: Uterine serous carcinoma (USC) is an aggressive subtype of endometrial cancer that commonly harbors HER2 gene amplification. We investigated the effectiveness of HER2 inhibition using lapatinib and trastuzumab in vitro and in xenografts derived from USC cell lines and USC patient-derived xenografts. Experimental Design: Immunohistochemistry and FISH were performed to assess HER2 expression in 42 primary USC specimens. ARK1, ARK2, and SPEC2 cell lines were treated with trastuzumab or lapatinib. Cohorts of mice harboring xenografts derived from ARK2 and SPEC2 cell lines and EnCa1 and EnCa2 primary human USC samples were treated with either vehicle, trastuzumab, lapatinib, or the combination of trastuzumab and lapatinib. Acute and chronic posttreatment tumor samples were assessed for downstream signaling alterations and examined for apoptosis and proliferation. Results: HER2 gene amplification (24%) correlated significantly with HER2 protein overexpression (55%). All models were impervious to single-agent trastuzumab treatment. Lapatinib decreased in vitro proliferation of all cell lines and in vivo growth of HER2-amplified xenografts (ARK2, EnCa1). In addition, dual therapy with trastuzumab and lapatinib resulted in significant antitumor activity only in ARK2 and EnCa1 tumors. Dual HER2 therapy induced on target alteration of downstream MAPK and PI3K pathway mediators only in HER2-amplified models, and was associated with increased apoptosis and decreased proliferation. Conclusions: Although trastuzumab alone did not impact USC growth, dual anti-HER2 therapy with lapatinib led to improved inhibition of tumor growth in HER2-amplified USC and may be a promising avenue for future investigation.

A Member of the p38 Mitogen-Activated Protein Kinase Family Is Responsible for Transcriptional Induction of Dopa decarboxylase in the Epidermis of Drosophila melanogaster during the Innate Immune Response

ABSTRACT Drosophila innate immunity is controlled primarily by the activation of IMD (immune deficiency) or Toll signaling leading to the production of antimicrobial peptides (AMPs). IMD signaling also activates the JUN N-terminal kinase (JNK) cascade, which is responsible for immune induction of non-antimicrobial peptide immune gene transcription though the transcription factor AP-1. Transcription of the Dopa decarboxylase (Ddc) gene is induced in response to gram-negative and gram-positive septic injury, but not aseptic wounding. Transcription is induced throughout the epidermis and not specifically at the site of infection. Ddc transcripts are detectible within 2 h and remain high for several hours following infection with either gram-negative or gram-positive bacteria. Using Ddc-green fluorescent protein (GFP) reporter gene constructs, we show that a conserved consensus AP-1 binding site upstream of the Ddc transcription start site is required for induction. However, neither the Toll, IMD, nor JNK pathway is involved. Rather, Ddc transcription depends on a previously uncharacterized member of the p38 mitogen-activated protein kinase family, p38c. We propose that the involvement of DDC in a new pathway involved in Drosophila immunity increases the levels of dopamine, which is metabolized to produce reactive quinones that exert an antimicrobial effect on invading bacteria.
A Rank Statistics Approach to the Consistency of a General Bootstrap

A general notion of a bootstrapped mean constructed by exchangeably weighting sample points is introduced. Consistency of this generalized bootstrapped mean, which includes proposals of Efron and Rubin among others, is proved by classical linear rank statistics theory. The consistency of generalized bootstrapped empirical and quantile processes is also established.
Prognostic value of receptor conversion after neoadjuvant chemotherapy in breast cancer patients: a prospective observational study

The hormone receptor (HR) status and human epidermal growth hormone receptor 2 (HER2) status of patients with breast cancer may change following neoadjuvant chemotherapy (NCT). This prospective observational study aimed to evaluate the prognostic impact of receptor conversion in breast cancer patients treated with NCT.Of the 423 consecutive patients who had residual disease in the breast after NCT, 55 (13.0%) changed from HR (+) to HR (−), 23 (5.4%) changed from HR (−) to HR (+), 27 (6.4%) changed from HER2 (+) to HER2 (−), and 13 (3.1%) changed from HER2 (−) to HER2 (+). A total of 54 (12.8%) changed to the triple-negative (TN) tumor phenotype. The loss of HR positivity was an independent prognostic factor for worse disease-free survival (DFS) and worse overall survival (OS) in multivariate survival analysis. Furthermore, the switch to the TN phenotype after NCT was another independent prognostic factor for worse survival for both DFS and OS. In conclusion, patients with breast cancer may experience changes in HR status, HER2 status and tumor phenotype after NCT. The loss of HR positivity and the switch to the TN phenotype after NCT were associated with a worse patient outcome.
GLP‐1 signals via ERK in peripheral nerve and prevents nerve dysfunction in diabetic mice

Aim: Glucagon‐like peptide‐1 (GLP‐1) is an incretin hormone that induces glucose‐dependent insulin secretion and may have neurotrophic properties. Our aim was to identify the presence and activity of GLP‐1 receptors (GLP‐1Rs) in peripheral nerve and to assess the impact of GLP‐1R agonists on diabetes‐induced nerve disorders.
