Elucidating the Roles of Maternal Overcontrol and Warmth in the Development of Childhood Anxiety and Depression: A Moderated Mediation Framework.

Studies have linked childhood anxiety and depression with parenting characterized by high control and low warmth. However, few studies have examined how control and warmth may work together to influence internalizing symptoms in children. Therefore, the goal of this study was to examine the moderating effect of warmth on the relationship between overcontrol and anxiety and depressive symptoms, as well as whether negative thoughts serve as a mediator of these pathways. A total of 182 fourth and fifth grade children completed measures of maternal parenting behavior, negative thoughts, and anxiety and depressive symptoms. Results showed an interaction between overcontrol and warmth for depressive but not anxiety symptoms. Furthermore, low warmth increased the strength of the mediating relationship between overcontrol and depression via thoughts of personal failure. Findings may signal a need for early interventions to address parenting behaviors, such as controlling behaviors, in parents of children at risk for internalizing difficulties.

Resistance of New Zealand Provenance Leptospermum scoparium, Kunzea robusta, Kunzea linearis, and Metrosideros excelsa to Austropuccinia psidii.

Resistance to the pandemic strain of Austropuccinia psidii was identified in New Zealand provenance Leptospermum scoparium, Kunzea robusta, and K. linearis plants. Only 1 Metrosideros excelsa-resistant plant was found (of the 570 tested) and no resistant plants of either Lophomyrtus bullata or L. obcordata were found. Three types of resistance were identified in Leptospermum scoparium. The first two, a putative immune response and a hypersensitive response, are leaf resistance mechanisms found in other myrtaceous species while on the lateral and main stems a putative immune stem resistance was also observed. Both leaf and stem infection were found on K. robusta and K. linearis plants as well as branch tip dieback that developed on almost 50% of the plants. L. scoparium, K. robusta, and K. linearis are the first myrtaceous species where consistent infection of stems has been observed in artificial inoculation trials. This new finding and the first observation of significant branch tip dieback of plants of the two Kunzea spp. resulted in the development of two new myrtle rust disease severity assessment scales. Significant seed family and provenance effects were found in L. scoparium, K. robusta, and K. linearis: some families produced significantly more plants with leaf, stem, and (in Kunzea spp.) branch tip dieback resistance, and provenances provided different percentages of resistant families and plants. The distribution of the disease symptoms on plants from the same seed family, and between plants from different seed families, suggested that the leaf, stem, and branch tip dieback resistances were the result of independent disease resistance mechanisms.

Who's who? Championing the '#TheatreCapChallenge'.

Our Developing Perioperative Practice service improvement project, sponsored by the Royal Bournemouth Hospital, addressed whether the remarkably simple idea of putting names and roles on hats in theatre would improve communication and patient care. We were inspired by our own experiences as a group of student Operating Department Practitioners: unfamiliarity with members of the team, wanting to feel included in the work but not out of our depth, and by social media campaigns such as the '#TheatreCapChallenge' and '#hellomynameis', aiming to humanise care and increase patient safety. Researching, clinically trialling and presenting this project gave us a systematic approach to improving the quality of care within the theatre environment.

Do Social Threat Cognitions Decrease With School-Based CBT and Predict Treatment Outcome in Adolescents With Social Anxiety Disorder?

Evidence suggests that Social Anxiety Disorder (SAD) is less responsive to cognitive behavioral treatment (CBT) compared to other anxiety disorders. Therefore, exploring what might facilitate clinical benefit is essential. Social threat cognitions, characterized by exaggerated perceptions of negative evaluation by others, may be one important avenue to examine. The current study investigated whether youths' social threat cognitions decreased with Skills for Academic and Social Success (SASS), a group, school-based CBT designed for SAD, and whether decreases predicted SAD severity and treatment response. Participants included 138 high school students with SAD randomly assigned to SASS, or a nonspecific school counseling intervention. SASS participants showed significantly decreased social threat cognitions at 5-month follow-up. Treatment responders had significantly greater reductions in social threat cognitions compared to nonresponders at post-intervention and follow-up. These findings suggest that social threat cognitions may be important to assess and monitor when treating youth with SAD.

Effects of cognitive behavioral therapy for insomnia and armodafinil on quality of life in cancer survivors: a randomized placebo-controlled trial.

PURPOSE: Cancer-related insomnia is associated with diminished quality of life (QOL), suggesting that improvement in insomnia may improve QOL in cancer survivors. Cognitive behavioral therapy for insomnia (CBT-I) has been shown to improve insomnia, but less is known regarding its effect on QOL and whether improvement in insomnia corresponds to improved QOL. The present analysis examines the effects of CBT-I, with and without armodafinil, on QOL both directly and indirectly through improvements of insomnia. METHODS: This is an analysis of 95 cancer survivors for a specified secondary aim of a four-arm randomized controlled trial assessing the combined and individual effects of CBT-I and armodafinil to improve insomnia. QOL and insomnia severity were assessed before, during the intervention, at post-intervention, and 3 months later by Functional Assessment of Cancer Therapy-General and Insomnia Severity Index, respectively. RESULTS: Mean change in QOL from pre- to post-intervention for CBT-I + placebo, CBT-I + armodafinil, armodafinil, and placebo was 9.6 (SE = 1.8; p < 0.0001), 11.6 (SE = 1.8; p < 0.0001), -0.2 (SE = 3.2; p = 0.964), and 3.3 (SE = 2.0; p = 0.124), respectively. ANCOVA controlling for pre-intervention scores showed that participants receiving CBT-I had significantly improved QOL at post-intervention compared to those not receiving CBT-I (p < 0.0001, effect size = 0.57), with benefits being maintained at the 3-month follow-up. Path analysis revealed that this improvement in QOL was due to improvement in insomnia severity (p = 0.002), and Pearson correlations showed that changes in QOL from pre- to post-intervention were significantly associated with concurrent changes in insomnia severity (r = -0.56; p < 0.0001). Armodafinil had no effect on QOL for those who did or did not receive it (p = 0.976; effect size = -0.004). CONCLUSION: In cancer survivors with insomnia, CBT-I resulted in clinically significant improvement in QOL via improvement in insomnia. This improvement in QOL remained stable even 3 months after completing CBT-I. IMPLICATIONS FOR CANCER SURVIVORS: Considering the high prevalence of insomnia and its detrimental impact on QOL in cancer survivors and the effectiveness of CBT-I in alleviating insomnia, it is important that evidence-based non-pharmacological sleep interventions such as CBT-I be provided as an integral part of cancer care.

Nausea and disturbed sleep as predictors of cancer-related fatigue in breast cancer patients: a multicenter NCORP study.

PURPOSE: Cancer-related fatigue (CRF) is a prevalent and distressing side effect of cancer and its treatment that remains inadequately understood and poorly managed. A better understanding of the factors contributing to CRF could result in more effective strategies for the prevention and treatment of CRF. The objectives of this study were to examine the prevalence, severity, and potential predictors for the early onset of CRF after chemotherapy cycle 1 in breast cancer patients. METHODS: We report on a secondary data analysis of 548 female breast cancer patients from a phase III multi-center randomized controlled trial examining antiemetic efficacy. CRF was assessed by the Brief Fatigue Inventory at pre- and post-chemotherapy cycle 1 as well as by the four-day diary. RESULTS: The prevalence of clinically relevant post-CRF was 75%. Linear regression showed that pre-treatment CRF, greater nausea, disturbed sleep, and younger age were significant risk factors for post-CRF (adjusted R2 = 0.39; P < 0.0001). Path modeling showed that nausea severity influenced post-CRF both directly and indirectly by influencing disturbed sleep. Similarly, pre-treatment CRF influenced post-CRF directly as well as indirectly through both nausea severity and disturbed sleep. Pearson correlations showed that changes in CRF over time were significantly correlated with concurrent changes in nausea severity (r = 0.41; P < 0.0001) and in disturbed sleep (r = 0.20; P < 0.0001). CONCLUSION: This study showed a high prevalence (75%) of clinically relevant CRF in breast cancer patients following their initial chemotherapy, and that nausea severity, disturbed sleep, pre-treatment CRF, and age were significant predictors of symptom.

Total-Body Irradiation Exacerbates Dissemination of Cutaneous Candida Albicans Infection.

Exposure to radiation, particularly a large or total-body dose, weakens the immune system through loss of bone marrow precursor cells, as well as diminished populations of circulating and tissue-resident immune cells. One such population is the skin-resident immune cells. Changes in the skin environment can be of particular importance as the skin is also host to a number of commensal organisms, including Candida albicans , a species of fungus that causes opportunistic infections in immunocompromised patients. In a previous study, we found that a 6 Gy sublethal dose of radiation in mice caused a reduction of cutaneous dendritic cells, indicating that the skin may have a poorer response to infection after irradiation. In this study, the same 6 Gy sublethal radiation dose led to a weakened response to a C. ablicans cutaneous infection, which resulted in systemic dissemination from the ear skin to the kidneys. However, this impaired response was mitigated through the use of interleukin-12 (IL-12) administered to the skin after irradiation. Concomitantly with this loss of local control of infection, we also observed a reduction of CD4+ and CD8+ T cells in the skin, as well as the reduced expression of IFN-γ, CXCL9 and IL-9, which influence T-cell infiltration and function in infected skin. These changes suggest a mechanism by which an impaired immune environment in the skin after a sublethal dose of radiation increases susceptibility to an opportunistic fungal infection. Thus, in the event of radiation exposure, it is important to include antifungal agents, or possibly IL-12, in the treatment regimen, particularly if wounds are involved that result in loss of the skin's physical barrier function.

Distribution, prevalence, and pathology of a microsporidian infecting freshwater sculpins.

Microsporidian infections are common in many fish species, yet detailed studies of these parasites in ecologically important wild populations are rare. Phylogenetic analysis using rDNA sequence data and parasite morphology indicate that mottled sculpin Cottus bairdii and slimy sculpin C. cognatus are hosts for Glugea sp. microsporidia in the northern USA. Glugea sp. is common in the Michigan populations sampled for this study, and prevalence was ≥ 70% in 4 of 6 infected populations (range -4 to 80%). Glugea sp. infection causes the formation of xenomas associated with the body wall, fat body, gonads, and kidneys. Infections range from mild to very heavy, with variable xenoma numbers and sizes. Female sculpin experience heavier infections and more frequent infection of the gonads relative to males. Glugea sp. is transmitted horizontally between hosts through ingestion of spores. Vertical transmission may also be possible, either by spores infecting eggs directly or by spores contaminating the surface of eggs in the ovary or in the nest. The frequency and route of vertical transmission requires further study, but if it occurs, it may partly explain the high prevalence of infection. Our study combined with previous research suggests that additional molecular data and cross-infection experiments should be conducted to clarify species designations in the genus Glugea.

Can school counselors deliver cognitive-behavioral treatment for social anxiety effectively? A randomized controlled trial.

BACKGROUND: Social anxiety disorder (SAD) typically onsets in adolescence and is associated with multiple impairments. Despite promising clinical interventions, most socially anxious adolescents remain untreated. To address this clinical neglect, we developed a school-based, 12-week group intervention for youth with SAD, Skills for Academic and Social Success (SASS). When implemented by psychologists, SASS has been found effective. To promote dissemination and optimize treatment access, we tested whether school counselors could be effective treatment providers. METHOD: We randomized 138, ninth through 11th graders with SAD to one of three conditions: (a) SASS delivered by school counselors (C-SASS), (b) SASS delivered by psychologists (P-SASS), or (c) a control condition, Skills for Life (SFL), a nonspecific counseling program. Blind, independent, evaluations were conducted with parents and adolescents at baseline, post-intervention, and 5 months beyond treatment completion. We hypothesized that C-SASS and P-SASS would be superior to the control, immediately after treatment and at follow-up. No prediction was made about the relative efficacy of C-SASS and P-SASS. RESULTS: Compared to controls, adolescents treated with C-SASS or P-SASS experienced significantly greater improvement and reductions of anxiety at the end of treatment and follow-up. There were no significant differences between SASS delivered by school counselors and psychologists. CONCLUSION: With training, school counselors are effective treatment providers to adolescents with social anxiety, yielding benefits comparable to those obtained by specialized psychologists. Questions remain regarding means to maintain counselors' practice standards without external support.

Sexualized behaviors in cohorts of children in the child welfare system.

The current retrospective archival study investigated the patterns of normative sexualized behavior (NSB), problematic sexualized behavior (PSB), and sexual perpetration for three age cohorts of boys and girls in a high-risk child welfare sample. All children in the present sample had exhibited some form of PSB in the past. We hypothesized that the incidence rates (IR) of NSBs would increase linearly from the early childhood cohort (Ages 2/3-7) to the middle childhood cohort (Ages 8-11) to the preadolescence/adolescence cohort (Ages 12-17), for girls and boys. Although the base rate of sexual behaviors generally increases as children age, children tend to hide sexual behaviors starting at an early age. We therefore hypothesized that a concave quadratic trend would be evident for most PSBs. We further predicted that older children would have a greater incidence of PSB, as well as more victims, compared with younger children. We found the predicted upward linear trend for NSB for both girls and boys, with minimal IR differences between the early childhood and middle childhood cohorts. IRs were remarkably high and comparable across age groups for both boys and girls, with respect to the same three PSBs. For the two perpetration history variables, there was a concave effect, with girls and boys in the middle childhood cohort exhibiting the lowest IR. Results are explained in the context of previously established patterns of sexualized behavior, as well as the reporting of such behaviors.

Identification of Social Anxiety in Schools: The Utility of a Two-Step Screening Process.

Social anxiety disorder (SAD) is highly prevalent yet largely undetected and untreated in adolescents despite the availability of effective treatments. Implementing interventions in schools enhances recognition and access to treatment for SAD. However, without reliable means to accurately identify youth in need of services, school-based interventions are not feasible. The purpose of this study is to evaluate the utility of a two-step, school-based screening approach to identify youth with SAD. Students at three public high schools were screened with self-report questionnaires or nominated by school personnel. Subsequently, a brief telephone assessment of student symptoms was completed with students' parents. Results showed that using both questionnaires and telephone assessments yielded acceptable detection rates, while school staff nominations were not beneficial. This study provides support for the use of a two-step screening procedure consisting of student self-reports followed by brief parent telephone interviews to identify youth with clinically impairing social anxiety. Implications for enhancing school-based detection of and intervention for socially anxious adolescents are discussed.

Interleukin-12 preserves the cutaneous physical and immunological barrier after radiation exposure.

The United States continues to be a prime target for attack by terrorist organizations in which nuclear detonation and dispersal of radiological material are legitimate threats. Such attacks could have devastating consequences to large populations, in the form of radiation injury to various human organ systems. One of these at risk organs is the cutaneous system, which forms both a physical and immunological barrier to the surrounding environment and is particularly sensitive to ionizing radiation. Therefore, increased efforts to develop medical countermeasures for treatment of the deleterious effects of cutaneous radiation exposure are essential. Interleukin-12 (IL-12) was shown to elicit protective effects against radiation injury on radiosensitive systems such as the bone marrow and gastrointestinal tract. In this article, we examined if IL-12 could protect the cutaneous system from a combined radiation injury in the form of sublethal total body irradiation and beta-radiation burn (ß-burn) directly to the skin. Combined radiation injury resulted in a breakdown in skin integrity as measured by transepidermal water loss, size of ß-burn lesion and an exacerbated loss of surveillant cutaneous dendritic cells. Interestingly, intradermal administration of IL-12 48 h postirradiation reduced transepidermal water loss and burn size, as well as retention of cutaneous dendritic cells. Our data identify IL-12 as a potential mitigator of radiation-induced skin injury and argue for the further development of this cytokine as a radiation countermeasure.

A phase III randomized, placebo-controlled study of topical amitriptyline and ketamine for chemotherapy-induced peripheral neuropathy (CIPN): a University of Rochester CCOP study of 462 cancer survivors.

PURPOSE: Chemotherapy-induced peripheral neuropathy (CIPN) occurs in as high as 70% of patients receiving certain types of chemotherapy agents. The FDA has yet to approve a therapy for CIPN. The aim of this multicenter, phase III, randomized, double-blind, placebo-controlled trial was to investigate the efficacy of 2% ketamine plus 4% amitriptyline (KA) cream for reducing CIPN. METHODS: Cancer survivors who completed chemotherapy at least 1 month prior and had CIPN (>4 out of 10) were enrolled (N=462). CIPN was assessed using average scores from a 7-day daily diary that asks patients to rate the average "pain, numbness, or tingling in [their] hands and feet over the past 24 h" on an 11-point numeric rating scale at baseline and 6 weeks post intervention. ANCOVA was used to measure differences in 6-week CIPN with effects including baseline CIPN, KA treatment arm, and previous taxane therapy (Y/N). RESULTS: The KA treatment showed no effect on 6-week CIPN scores (adjusted mean difference=-0.17, p=0.363). CONCLUSIONS: This study suggests that KA cream does not decrease CIPN symptoms in cancer survivors.

Bias Assessment of General Chemistry Analytes using Commutable Samples.

Harmonisation of reference intervals for routine general chemistry analytes has been a goal for many years. Analytical bias may prevent this harmonisation. To determine if analytical bias is present when comparing methods, the use of commutable samples, or samples that have the same properties as the clinical samples routinely analysed, should be used as reference samples to eliminate the possibility of matrix effect. The use of commutable samples has improved the identification of unacceptable analytical performance in the Netherlands and Spain. The International Federation of Clinical Chemistry and Laboratory Medicine (IFCC) has undertaken a pilot study using commutable samples in an attempt to determine not only country specific reference intervals but to make them comparable between countries. Australia and New Zealand, through the Australasian Association of Clinical Biochemists (AACB), have also undertaken an assessment of analytical bias using commutable samples and determined that of the 27 general chemistry analytes studied, 19 showed sufficiently small between method biases as to not prevent harmonisation of reference intervals. Application of evidence based approaches including the determination of analytical bias using commutable material is necessary when seeking to harmonise reference intervals.

Harmonising adult and paediatric reference intervals in australia and new zealand: an evidence-based approach for establishing a first panel of chemistry analytes.

Scientific evidence supports the use of common reference intervals (RIs) for many general chemistry analytes, in particular those with sound calibration and traceability in place. Already the Nordic countries and United Kingdom have largely achieved harmonised RIs. Following a series of workshops organised by the Australasian Association of Clinical Biochemists (AACB) between 2012 and 2014 at which an evidence-based approach for determination of common intervals was developed, pathology organisations in Australia and New Zealand have reached a scientific consensus on what adult and paediatric intervals we should use across Australasia. The aim of this report is to describe the processes that the AACB and the Royal College of Pathologists of Australasia have taken towards recommending the implementation of a first panel of common RIs for use in Australasia.

Evidence-based approach to harmonised reference intervals.

Although we are in the era of evidence-based medicine, there is still a substantial gap between theory and current practice with the application of reference intervals as decision making tools. Different laboratories may have different reference intervals for the same tests using the same analytical methods and platforms. These differences have the potential to confuse physicians making the assessment and monitoring of patients more difficult by providing discordant information. This paper attempts to demonstrate how to use evidence-based approach for harmonising reference intervals. In order to consider harmonisation we must first have an appreciation of the various factors that influence the determination of that reference interval such as the choice of individuals within the population studied, biological variability of the analyte studied, partitioning, sample collection, analytical aspects such as bias and statistical models. An a priori approach for determining reference intervals, whilst recommended, may be beyond the scope of most laboratories and consideration should be given to the use of a validated indirect a posteriori approach. Regardless of method used, the continuing application of an evidence-based approach in harmonised reference intervals to meet the quality expectations of physicians should be pursued.

18F-fluorodeoxyglucose positron emission tomography-computed tomography imaging in the management of Merkel cell carcinoma: a single-institution retrospective study.

BACKGROUND: Merkel cell carcinoma (MCC) is among the deadliest of cutaneous malignancies. A lack of consensus evaluation and treatment guidelines has hindered management of this disease. The utility of simultaneous positron emission tomography and computed tomography (PET/CT) has been demonstrated for a variety of tumors yet remains underinvestigated for MCC. OBJECTIVES: To report the value of fluorodeoxyglucose PET/CT imaging in the initial staging and ongoing management of individuals with MCC and to determine whether any patient or tumor characteristics may predict when PET/CT is more likely to have greater influence on medical decision-making. MATERIALS AND METHODS: A single-institution retrospective chart review was conducted of all patients diagnosed with MCC who underwent FDG-PET/CT scanning from 2007 to 2010. The outcome of each of these studies was evaluated as to the influence on patient staging and management. Patient clinical information and information on gross and microscopic tumor characteristics were collected and analyzed. RESULTS: Twenty patients underwent 39 PET/CT scans. Results of PET/CT imaging revealed previously unknown information related to MCC in four (20%) patients, leading to changes in management in three of these four cases. Three previously unknown neoplasms were detected. CONCLUSION: Fluorodeoxyglucose-positron emission tomography and computed tomography is a valuable tool for initial staging and to assess response to therapy of patients diagnosed with MCC. Larger prospective studies would be required to establish the optimal timing for this imaging modality.

Curcumin for radiation dermatitis: a randomized, double-blind, placebo-controlled clinical trial of thirty breast cancer patients.

Radiation dermatitis occurs in approximately 95% of patients receiving radiotherapy (RT) for breast cancer. We conducted a randomized, double-blind, placebo-controlled clinical trial to assess the ability of curcumin to reduce radiation dermatitis severity in 30 breast cancer patients. Eligible patients were adult females with noninflammatory breast cancer or carcinoma in situ prescribed RT without concurrent chemotherapy. Randomized patients took 2.0 grams of curcumin or placebo orally three times per day (i.e., 6.0 grams daily) throughout their course of RT. Weekly assessments included Radiation Dermatitis Severity (RDS) score, presence of moist desquamation, redness measurement, McGill Pain Questionnaire-Short Form and Symptom Inventory questionnaire. The 30 evaluable patients were primarily white (90%) and had a mean age of 58.1 years. Standard pooled variances t test showed that curcumin reduced RDS at end of treatment compared to placebo (mean RDS = 2.6 vs. 3.4; P = 0.008). Fisher's exact test revealed that fewer curcumin-treated patients had moist desquamation (28.6% vs. 87.5%; P = 0.002). No significant differences were observed between arms for demographics, compliance, radiation skin dose, redness, pain or symptoms. In conclusion, oral curcumin, 6.0 g daily during radiotherapy, reduced the severity of radiation dermatitis in breast cancer patients.

Electrocardiograph changes, troponin levels and cardiac complications after orthopaedic surgery.

INTRODUCTION: The relationship between electrocardiograph (ECG) changes and troponin levels after the emergency orthopaedic surgery are not well characterised. The aim of this study was to determine the correlation between ECG changes (ischaemia or arrhythmia), troponin elevations perioperatively and cardiac complications. MATERIALS AND METHODS: One hundred and eighty-seven orthopaedic patients over 60 years of age were prospectively tested for troponin I and ECGs were performed on the fi rst 3 postoperative mornings or until discharge. RESULTS: The incidences of pre- and postoperative troponin elevation were 15.5% and 37.4% respectively, the majority were asymptomatically detected. Most of the patients who sustained a troponin rise did not have any concomitant ECG changes (51/70 or 72.9%). Postoperative ECG changes were noted in 18.4% (34/185) and of those with ECG changes, slightly more than half (55.9%) had a troponin elevation. Most ECG changes occurred on postoperative day 1 and were non-ST elevation in type. ECG changes occurred more frequently with higher troponin levels. Postoperative troponin elevation (P = 0.018) and not preoperative troponin level (P = 0.060) was associated with ECG changes on univariate analysis. Two premorbid factors were predictors of postoperative ECG changes using multivariate logistical regression; age [odds ratio (OR), 1.05; 95% CI, 1.005 to 1.100, P = 0.029) and sex OR, 2.4; 95% CI, 1.069 to 5.446, P = 0.034). Twenty patients sustained postoperative cardiac complications; 9 (45%) were associated with ECG changes and 16 (80%) with postoperative troponin elevation. Pre- or postoperative troponin elevation better predicted cardiac complications compared with preoperative ECG changes. CONCLUSION: Electrocardiograph changes do not necessarily accompany troponin elevations after the emergency orthopaedic surgery but are more likely to have higher troponin levels. The best predictor of postoperative cardiac complications is troponin elevation.
