Family contributions to sport performance and their utility in predicting appropriate referrals to mental health optimization programmes

ABSTRACT Limited research has examined the contributions of sport-specific family relationship problems to athlete mental health. In the current study we examined the extent to which collegiate athletes’ family problems (as measured by the Student Athlete Relationship Instrument factors, SARI) predict athletes’ general mental health distress and specific mental health symptoms that are relatively common in athletes (i.e. depression, anxiety, and drug and alcohol use). The study included 85 collegiate athletes (intramural, n = 26; club sport, n = 12; NCAA Division I, n = 47). We hypothesized that both general mental health distress and commonly evidenced mental health symptoms would be predicted by athletes’ responses to the SARI factors (Poor Relationship and Lack of Support, General Pressure, Pressure to Quit or Continue Unsafely, Embarrassing Comments, and Negative Attitude). Results indicated that all of the aforementioned SARI factors predicted athletes’ ratings of depression and general mental health distress levels. Only the General Pressure SARI factor predicted athletes’ anxiety and drug use. Alcohol use was not predicted by any of the SARI factors. Receiver operating characteristic (ROC) analyses indicated that sport-specific problems in family relationships provided a good classification of athletes at risk for general mental health distress, depression, and anxiety. Practice implications are discussed in light of the results.
Factory and construction work is associated with an increased risk of severe lumbar spinal stenosis on MRI: A case control analysis within the wakayama spine study

Background To explore the association of MRI‐diagnosed severe lumbar spinal stenosis with occupation. Methods Occupational data were collected by questionnaire and all participants underwent spine MRI scans using the same protocol. Central lumbar spinal stenosis (LSS) was graded qualitatively. Those with severe LSS (>two‐thirds narrowing) were compared with the controls with lesser degrees of stenosis or no stenosis. Results Data were available for 722 subjects, mean age 70.1 years. 239 (33%) cases with severe LSS were identified. Factory/construction workers had an almost four‐fold increased risk of severe LSS after adjustment for age, sex, smoking, and walking speed amongst those aged <75 years (OR 3.97, 95%CI 1.46‐10.85). Severe LSS was also associated with squatting ≥1 h/day (OR 1.76, 95%CI 1.01‐3.07) but this association became non‐significant after adjustment. Conclusion Further research is needed but this study adds more evidence that occupational factors are associated with an increased risk and/or severity of degenerative disease of the lumbar spine.
Caregivers of individuals with schizophrenia: who are they and what are their challenges?

Purpose of review To better understand the overall burden of schizophrenia, we aimed to explore informal caregivers’ experiences by evaluating the current evidence on caregiver and patient characteristics, the type of care provided by caregivers, and the impacts of caregiving on caregivers’ lives. Recent findings Caregivers provide direct care, assistance with activities of daily living, and emotional, social, and financial support to individuals with schizophrenia. Increased duration of illness and of care, severe or persistent schizophrenia symptoms, criticism of the care recipient, financial burden, and patient disability intensify caregiver burden. Caregivers of individuals with persistent symptoms often feel overwhelmed, stressed, drained, burdened, frustrated, or angry. Financial impacts of caregiving include treatment costs for care recipients, providing financial support, and lost productivity and income. Depression and anxiety are common health impacts for caregivers, who also have increased physical healthcare resource use relative to healthy controls. Caregiver burden is reduced by formal support programs to improve caregivers’ stress management and coping skills and informal sources of social support. Summary Targeted efforts to improve access to care and provide additional support for caregivers are needed to alleviate caregiver burden and improve outcomes for individuals with schizophrenia.
The working set model for program behavior

an adequate model for program behavior. In this paper a new model, the "working set model," is developed. The working set of pages associated with a process, defined to be the collection of its most recently used pages, provides knowledge vital to the dynamic management of paged memories. "Process" and "working set" are shown to be manifestations of the same ongoing computational activity; then "processor demand" and "memory demand" are defined; and resource allocation is formulated as the problem of balancing demands against available equipment.
Effect of radiologists' diagnostic work-up volume on interpretive performance.

PURPOSE To examine radiologists' screening performance in relation to the number of diagnostic work-ups performed after abnormal findings are discovered at screening mammography by the same radiologist or by different radiologists. MATERIALS AND METHODS In an institutional review board-approved HIPAA-compliant study, the authors linked 651 671 screening mammograms interpreted from 2002 to 2006 by 96 radiologists in the Breast Cancer Surveillance Consortium to cancer registries (standard of reference) to evaluate the performance of screening mammography (sensitivity, false-positive rate [ FPR false-positive rate ], and cancer detection rate [ CDR cancer detection rate ]). Logistic regression was used to assess the association between the volume of recalled screening mammograms ("own" mammograms, where the radiologist who interpreted the diagnostic image was the same radiologist who had interpreted the screening image, and "any" mammograms, where the radiologist who interpreted the diagnostic image may or may not have been the radiologist who interpreted the screening image) and screening performance and whether the association between total annual volume and performance differed according to the volume of diagnostic work-up. RESULTS Annually, 38% of radiologists performed the diagnostic work-up for 25 or fewer of their own recalled screening mammograms, 24% performed the work-up for 0-50, and 39% performed the work-up for more than 50. For the work-up of recalled screening mammograms from any radiologist, 24% of radiologists performed the work-up for 0-50 mammograms, 32% performed the work-up for 51-125, and 44% performed the work-up for more than 125. With increasing numbers of radiologist work-ups for their own recalled mammograms, the sensitivity (P = .039), FPR false-positive rate (P = .004), and CDR cancer detection rate (P < .001) of screening mammography increased, yielding a stepped increase in women recalled per cancer detected from 17.4 for 25 or fewer mammograms to 24.6 for more than 50 mammograms. Increases in work-ups for any radiologist yielded significant increases in FPR false-positive rate (P = .011) and CDR cancer detection rate (P = .001) and a nonsignificant increase in sensitivity (P = .15). Radiologists with a lower annual volume of any work-ups had consistently lower FPR false-positive rate , sensitivity, and CDR cancer detection rate at all annual interpretive volumes. CONCLUSION These findings support the hypothesis that radiologists may improve their screening performance by performing the diagnostic work-up for their own recalled screening mammograms and directly receiving feedback afforded by means of the outcomes associated with their initial decision to recall. Arranging for radiologists to work up a minimum number of their own recalled cases could improve screening performance but would need systems to facilitate this workflow.
Progesterone treatment in rats after severe global cerebral ischemia promotes hippocampal dentate gyrus neurogenesis and functional recovery

ABSTRACT Objective: Rats treated with progesterone (P4) after ischemia show an adequate functional performance despite a significant loss of hippocampal pyramidal neurons, suggesting that P4 could favour a permissive microenvironment for cerebral plasticity mechanisms. The possibility of P4 treatment promoting the survival of newly generated hippocampal neurons, in relation to the performance of ischemic rats in a spatial learning task, was assessed in this study. Methods: Adult male rats were subjected to a severe global cerebral ischemia episode (30 min) and treated with P4 or its vehicle at 15 min, 2, 6, 24, 48 and 72 h of reperfusion. From day 4 to 8 post-ischemia 5-bromo-2-deoxyuridine (BrdU) was administered to label proliferating cells. Twenty-one days post-ischemia, the rats were exposed to the Morris water maze to assess behavioral parameters of spatial learning and memory. Subsequently, the brain was perfusion-fixed and immunofluorescence procedures were performed to quantify the number of new mature neurons (BrdU+/NeuN+) in the dentate gyrus (DG) of the hippocampus. Results: Rats subjected to severe global cerebral ischemia and treated with P4 had a significantly better performance in spatial learning-memory tests, than those treated with vehicle, and a significantly higher number of new mature neurons (BrdU+/NeuN+) in the DG. Conclusion: These findings show that post-ischemia P4 treatment, following an episode of severe global cerebral ischemia, promotes the survival of newly generated hippocampal neurons in the DG, which may be one of the mechanisms of cerebral plasticity induced by the hormone, that underlie a successful functional performance in learning and memory tests.
Effect of fluoride dentifrices on white spot lesions during orthodontic treatment: A randomized trial.

OBJECTIVES To determine the effect of Clinpro 5000, Clinpro Tooth Crème, and MI-Paste Plus on the formation of white spot lesions in patients undergoing orthodontic treatment. MATERIALS AND METHODS Three prospective groups with 40 patients undergoing orthodontic treatment in each group were evaluated (total recruitment = 120 subjects). The selected product was brushed on for 2 minutes twice daily for 4 months. Subjects were reviewed for 4 months on a monthly basis. The Enamel Decalcification Index (EDI) was used to determine the number of white spot lesions per surface at each visit. RESULTS 100 subjects (35 using Clinpro 5000, 32 using Clinpro Tooth Crème, and 33 using MI Paste Plus) completed the study. The data lend strong support for Clinpro 5000 providing superior protection against enamel decalcification when compared to Clinpro Crème, and mixed support when compared to MI Paste Plus. CONCLUSIONS The use of Clinpro 5000, Clinpro Crème, and MI paste Plus all have a reduction effect on white spot lesions when compared to studies reported previously. Clinpro 5000 has a marginally better effect than the two other test pastes. The results of this study can be used by clinicians when deciding the effectiveness of using fluoride dentifrice products to prevent white spot lesions in their orthodontic practice (ClinicalTrials.gov ID: NCT03440996).
A common SNP in the UNG gene decreases ovarian cancer risk in BRCA2 mutation carriers

Single nucleotide polymorphisms (SNPs) in DNA glycosylase genes involved in the base excision repair (BER) pathway can modify breast and ovarian cancer risk in BRCA1 and BRCA2 mutation carriers. We previously found that SNP rs34259 in the uracil‐DNA glycosylase gene (UNG) might decrease ovarian cancer risk in BRCA2 mutation carriers. In the present study, we validated this finding in a larger series of familial breast and ovarian cancer patients to gain insights into how this UNG variant exerts its protective effect. We found that rs34259 is associated with significant UNG downregulation and with lower levels of DNA damage at telomeres. In addition, we found that this SNP is associated with significantly lower oxidative stress susceptibility and lower uracil accumulation at telomeres in BRCA2 mutation carriers. Our findings help to explain the association of this variant with a lower cancer risk in BRCA2 mutation carriers and highlight the importance of genetic changes in BER pathway genes as modifiers of cancer susceptibility for BRCA1 and BRCA2 mutation carriers.
Impairment of pupation by RNA interference-aided knockdown of Broad-Complex gene in Leptinotarsa decemlineata (Say)

Abstract Dietary delivery of bacterially expressed double-stranded RNA (dsRNA) has a great potential for management of Leptinotarsa decemlineata. An important first step is to discover possible RNA-interference (RNAi)-target genes effective against larvae, especially the old larvae. In the present paper, five putative Broad-Complex (BrC) cDNAs (Z1-Z4, and Z6) were identified in L. decemlineata. The expression of the five LdBrC isoforms was suppressed by juvenile hormone signaling, whereas the transcription was upregulated by 20-hydroxyecdysone signaling at the fourth (final) instar larval stage. Feeding of bacterially expressed dsBrC (derived from a common fragment of the five LdBrC variants) in the third- and fourth-instar larvae successfully knocked down the target mRNAs. For the fourth-instar LdBrC RNAi hypomorphs, they had a higher larval mortality compared with the controls. Moreover, most dsBrC-fed beetles did not pupate normally. After removal of the apolysed larval cuticle, a miniature adult was found. The adult head, compound eyes, prothorax, mesothorax, metathorax were found on the dorsal view. Distinct adult cuticle pigmentation was seen on the prothorax. The mouthparts, forelegs, midlegs, and hindlegs could be observed on the ventral view of the miniature adults. For the third-instar LdBrC RNAi specimens, around 20% moribund beetles remained as prepupae and finally died. Therefore, LdBrC is among the most attractive candidate genes for RNAi to control the fourth-instar larvae in L. decemlineata.
Postoperative outcomes of patients with chronic obstructive pulmonary disease undergoing coronary artery bypass grafting surgery

Introduction: Chronic obstructive pulmonary disease (COPD) is a frequent comorbid disease in patients undergoing coronary artery bypass grafting (CABG) surgery, with an incidence ranging from 4% to 20.5%. Conventionally, COPD was recognized as a surgical contraindication to CABG. Because of the recent improvements in surgical techniques, anesthesia, and postoperative management, CABG has been performed more commonly in patients with COPD. However, studies have shown the various effects of COPD on postoperative morbidity and mortality after CABG, and this remains to be well defined. Objectives: To compare the postoperative outcomes after CABG between patients with and those without COPD. Methods: A systematic search was conducted in the Cochrane Library, PubMed, EmBase, and Ovid databases (until May 10, 2018). Studies comparing perioperative results and mortality outcomes after CABG between patients with and those without COPD were evaluated independently by 2 reviewers to identify the potentially eligible studies. Review Manager and STATA software were used for statistical analyses. Results: No significant difference in the mortality rates were found between patients with and those without COPD. COPD was associated with a higher respiratory failure rate (odds ratio [OR] = 4.01; 95% CI: 1.19–13.51, P = .03; P <.001 for heterogeneity), higher pneumonia rate (OR = 2.92; 95% CI: 2.37–3.60, P <.00001; P = .73 for heterogeneity), higher stroke rate (OR = 2.91; 95% CI: 1.37–6.18, P = .005; P = .60 for heterogeneity), higher renal failure rate (OR = 1.60; 95% CI: 1.30–1.97, P <.00001; P = .19 for heterogeneity), and higher wound infection rate (OR = 2.16; 95% CI: 1.21–3.88, P = .01; P = .53 for heterogeneity) after CABG. Conclusions: Patients with COPD were at higher risks for developing postoperative morbidities, particularly pneumonia, respiratory failure, stroke, renal failure, and wound infection. Although COPD was not associated with a higher risk of mortality, caution should be taken when a patient with COPD is indicated for CABG, considering the higher odds of postoperative complications involving the respiratory system and others.
Temporally Distinct PD-L1 Expression by Tumor and Host Cells Contributes to Immune Escape

PD-L1 induction on tumor cells is IFNγ-dependent and transient, but becomes IFNγ-independent and long-lived on tumorassociated macrophages. Thus, assessing PD-L1 expression on both tumor and host cells may better stratify patients undergoing PD-1/PD-L1 blockade therapy. Antibody blockade of programmed death-1 (PD-1) or its ligand, PD-L1, has led to unprecedented therapeutic responses in certain tumor-bearing individuals, but PD-L1 expression's prognostic value in stratifying cancer patients for such treatment remains unclear. Reports conflict on the significance of correlations between PD-L1 on tumor cells and positive clinical outcomes to PD-1/PD-L1 blockade. We investigated this issue using genomically related, clonal subsets from the same methylcholanthrene-induced sarcoma: a highly immunogenic subset that is spontaneously eliminated in vivo by adaptive immunity and a less immunogenic subset that forms tumors in immunocompetent mice, but is sensitive to PD-1/PD-L1 blockade therapy. Using CRISPR/Cas9-induced loss-of-function approaches and overexpression gain-of-function techniques, we confirmed that PD-L1 on tumor cells is key to promoting tumor escape. In addition, the capacity of PD-L1 to suppress antitumor responses was inversely proportional to tumor cell antigenicity. PD-L1 expression on host cells, particularly tumor-associated macrophages (TAM), was also important for tumor immune escape. We demonstrated that induction of PD-L1 on tumor cells was IFNγ-dependent and transient, but PD-L1 induction on TAMs was of greater magnitude, only partially IFNγ dependent, and was stable over time. Thus, PD-L1 expression on either tumor cells or host immune cells could lead to tumor escape from immune control, indicating that total PD-L1 expression in the immediate tumor microenvironment may represent a more accurate biomarker for predicting response to PD-1/PD-L1 blockade therapy, compared with monitoring PD-L1 expression on tumor cells alone.

Angiopoietin-2 Inhibition Rescues Arteriovenous Malformation in a Smad4 Hereditary Hemorrhagic Telangiectasia Mouse Model

Background: Hereditary hemorrhagic telangiectasia is an autosomal dominant vascular disorder caused by heterozygous, loss-of-function mutations in 4 transforming growth factor beta (TGF&bgr;) pathway members, including the central transcriptional mediator of the TGF&bgr; pathway, Smad4. Loss of Smad4 causes the formation of inappropriate, fragile connections between arteries and veins called arteriovenous malformations (AVMs), which can hemorrhage leading to stroke, aneurysm, or death. Unfortunately, the molecular mechanisms underlying AVM pathogenesis remain poorly understood, and the TGF&bgr; downstream effectors responsible for hereditary hemorrhagic telangiectasia–associated AVM formation are currently unknown. Methods: To identify potential biological targets of the TGF&bgr; pathway involved in AVM formation, we performed RNA- and chromatin immunoprecipitation–sequencing experiments on BMP9 (bone morphogenetic protein 9)-stimulated endothelial cells (ECs) and isolated ECs from a Smad4-inducible, EC-specific knockout (Smad4-iECKO) mouse model that develops retinal AVMs. These sequencing studies identified the angiopoietin-Tek signaling pathway as a downstream target of SMAD4. We used monoclonal blocking antibodies to target a specific component in this pathway and assess its effects on AVM development. Results: Sequencing studies uncovered 212 potential biological targets involved in AVM formation, including the EC surface receptor, TEK (TEK receptor tyrosine kinase) and its antagonistic ligand, ANGPT2 (angiopoietin-2). In Smad4-iECKO mice, Angpt2 expression is robustly increased, whereas Tek levels are decreased, resulting in an overall reduction in angiopoietin-Tek signaling. We provide evidence that SMAD4 directly represses Angpt2 transcription in ECs. Inhibition of ANGPT2 function in Smad4-deficient mice, either before or after AVMs form, prevents and alleviates AVM formation and normalizes vessel diameters. These rescue effects are attributed to a reversion in EC morphological changes, such as cell size and shape that are altered in the absence of Smad4. Conclusions: Our studies provide a novel mechanism whereby the loss of Smad4 causes increased Angpt2 transcription in ECs leading to AVM formation, increased blood vessel calibers, and changes in EC morphology in the retina. Blockade of ANGPT2 function in an in vivo Smad4 model of hereditary hemorrhagic telangiectasia alleviated these vascular phenotypes, further implicating ANGPT2 as an important TGF&bgr; downstream mediator of AVM formation. Therefore, alternative approaches that target ANGPT2 function may have therapeutic value for the alleviation of hereditary hemorrhagic telangiectasia symptoms, such as AVMs.
“HIV is not an easily acceptable disease”: the role of HIV-related stigma in obtaining cervical cancer screening in India

ABSTRACT Women living with HIV (WLWH) are at high risk for cervical cancer (CC); however, many WLWH in India do not obtain regular CC screening. Little is known about facilitators and barriers of CC screening in this population. This qualitative study examined the relation of HIV-related stigma to obtaining CC screening among women in Surat, India. Semi-structured individual in-depth interviews were conducted between April 2015 and July 2015 with 25 WLWH at the New Civil Hospital Anti-Retroviral Centre and 15 stakeholders providing health care to WLWH. HIV-related stigma emerged as a considerable barrier to gynecologic care and CC screening among WLWH. Two major subthemes were identified: (1) perceptions of HIV-related normative stigma and enacted discrimination; and (2) HIV status disclosure in the context of health care and CC screening. Stakeholders described a general awareness of HIV-related stigma as a barrier to care for WLWH, while WLWH focused on experiences of enacted discrimination. Both patients and stakeholders described that concerns about disclosure and fear of stigma hinder WLWH in India from obtaining health care and CC screening. Findings suggest that interventions to increase cancer screening among WLWH in India should address the role of HIV-related stigma to be maximally effective.
