Non-verbal nurse-parturient communication in labor in Portuguese-speaking countries*

Objective: to analyze nonverbal communication between nurse and parturient during the active phase of labor in two Portuguese-speaking countries. Method: a quantitative and analytical study, whose sample consisted of 709 interactions that used the nonverbal communication of nurses and parturients. The analyzed variables were: distance; posture; axis; contact; emblematic gestures; illustrator gestures and regulatory gestures. For the analysis of the data, the Chi-Square and Likelihood Ratio tests were used. Results: the intimate distance between nurse and parturient in both countries (p = 0.005) prevailed. In both, touch was the most commonly used form of contact (p <0.0001). In both countries, the parturient remained lying down (p <0.0001). In relation to the established contact (p <0.0001), the parturient did not use contact. The face-to-face axis predominated in the interactions in both countries between nurse-parturient (p <0.0001) and parturient-nurse (p <0.0001). Conclusion: similarities were observed in non-verbal communication between nurses and parturients in both countries. However, there are differences such as the established contact between Brazilian and Cape Verdean nurses to parturients.
Intracellular metabolism and potential cardiotoxicity of a β-D-2’-C-methyl-2,6-diaminopurine ribonucleoside phosphoramidate that inhibits hepatitis C virus replication

Abstract β-D-2’-C-Methyl-2,6-diaminopurine ribonucleoside (2’-C-Me-DAPN) phosphoramidate prodrug (DAPN-PD) is a selective hepatitis C virus inhibitor that is metabolized intracellularly into two active metabolites: 2’-C-Methyl-DAPN triphosphate (2’-C-Me-DAPN-TP) and 2’-C-methyl-guanosine 5’-triphosphate (2’-C-Me-GTP). BMS-986094 and IDX-184 are also bioconverted to 2’-C-Me-GTP. A phase IIb clinical trial with BMS-986094 was abruptly halted due to adverse cardiac and renal effects. Herein, we developed an efficient large scale synthesis of DAPN-PD and determined intracellular pharmacology of DAPN-PD in comparison with BMS-986094 and IDX-184, versus Huh-7, HepG2 and interspecies primary hepatocytes and human cardiomyocytes. Imaging data of drug treated human cardiomyocytes was found to be most useful in determining toxicity potential as no obvious beating rate change was observed for IDX-184 up to 50 µM up at 48 h. However, with BMS-986094 and DAPN-PD at 10 µM changes to both beat rate and rhythm were noted.
Neuronal ER–plasma membrane junctions organized by Kv2–VAP pairing recruit Nir proteins and affect phosphoinositide homeostasis

The association of plasma membrane (PM)-localized voltage-gated potassium (Kv2) channels with endoplasmic reticulum (ER)-localized vesicle-associated membrane protein-associated proteins VAPA and VAPB defines ER–PM junctions in mammalian brain neurons. Here, we used proteomics to identify proteins associated with Kv2/VAP-containing ER–PM junctions. We found that the VAP-interacting membrane-associated phosphatidylinositol (PtdIns) transfer proteins PYK2 N-terminal domain-interacting receptor 2 (Nir2) and Nir3 specifically associate with Kv2.1 complexes. When coexpressed with Kv2.1 and VAPA in HEK293T cells, Nir2 colocalized with cell-surface–conducting and -nonconducting Kv2.1 isoforms. This was enhanced by muscarinic-mediated PtdIns(4,5)P2 hydrolysis, leading to dynamic recruitment of Nir2 to Kv2.1 clusters. In cultured rat hippocampal neurons, exogenously expressed Nir2 did not strongly colocalize with Kv2.1, unless exogenous VAPA was also expressed, supporting the notion that VAPA mediates the spatial association of Kv2.1 and Nir2. Immunolabeling signals of endogenous Kv2.1, Nir2, and VAP puncta were spatially correlated in cultured neurons. Fluorescence-recovery-after-photobleaching experiments revealed that Kv2.1, VAPA, and Nir2 have comparable turnover rates at ER–PM junctions, suggesting that they form complexes at these sites. Exogenous Kv2.1 expression in HEK293T cells resulted in significant differences in the kinetics of PtdIns(4,5)P2 recovery following repetitive muscarinic stimulation, with no apparent impact on resting PtdIns(4,5)P2 or PtdIns(4)P levels. Finally, the brains of Kv2.1-knockout mice had altered composition of PtdIns lipids, suggesting a crucial role for native Kv2.1-containing ER–PM junctions in regulating PtdIns lipid metabolism in brain neurons. These results suggest that ER–PM junctions formed by Kv2 channel–VAP pairing regulate PtdIns lipid homeostasis via VAP-associated PtdIns transfer proteins.
Reliability and validation of Swedish translation of Beliefs about Medication Specific (BMQ-Specific) and Brief Illness Perception Questionnaire (B-IPQ) for use in adolescents with attention-deficit hyperactivity disorder

Abstract Objectives: The purpose of this study was to assess the reliability and validity of Swedish translations of the Beliefs about Medicines Questionnaire-Specific (BMQ-Specific) and Brief Illness Perception Questionnaire (B-IPQ) for use in adolescents with ADHD. Methods: Forward and backward translations of the BMQ-Specific and B-IPQ scales to Swedish were conducted and reviewed by adolescents with ADHD and professionals. The validity and reliability of both questionnaires were investigated in a cross-sectional study of 101 adolescents (13–17 years) on a long-term prescription of ADHD medication recruited from two child and adolescent psychiatric outpatient clinics in Sweden. Results: Regarding the BMQ-Specific, principal component analysis (PCA) loadings confirmed the previously defined components of Specific-Necessity and Specific-Concern. The PCA for B-IPQ revealed two components, the first one, B-IPQ Consequences, captured questions regarding perceptions of the implication of having ADHD (items 1, 2, 5, 6 and 8) and the second one, B-IPQ-Control, the perceptions of the capability to manage the ADHD disorder (items 3, 4 and 7). The Cronbach alpha coefficients for BMQ-Specific-Necessity scale was α = 0.80, for BMQ-Specific-Concern scale α = 0.75, B-IPQ Consequences α = 0.74 and for B-IPQ-Control α = 0.44. Conclusions: The present results prove the Swedish translation of BMQ-Specific and B-IPQ to be valid and reliable for utilization in adolescents with ADHD. The PCA confirmed the original components for BMQ-Specific and the recent findings of two main B-IPQ components describing emotional and cognitive implications versus the capability for self-care maintenance of ADHD.
Family history of cancer and subsequent risk of cancer: A large‐scale population‐based prospective study in Japan

Family history (FH) of cancer is an important factor of increased risk of several cancers. Although the association between FH of cancer and concordant cancer risk has been reported in many previous epidemiological studies, no comprehensive prospective study with adjustment for lifestyle habits has evaluated the association of FH of cancer and concordant cancer risk. We investigated the association between FH of cancer and concordant cancer risk in a Japanese population‐based prospective study, initiated in 1990 for cohort I and in 1993 for cohort II. We analyzed data on 103,707 eligible subjects without a history of cancer who responded to a self‐administered questionnaire including FH of cancer at baseline. Study subjects were followed through 2012 and analyzed using multivariable‐adjusted Cox proportional hazards regression models. During 1,802,581 person‐years of follow‐up, a total of 16,336 newly diagnosed cancers were identified. Any site (Hazard ratios = 1.11 (95% confidence interval = 1.07–1.15]), esophagus (2.11 [1.00–4.45]), stomach (1.36 [1.19–1.55]), liver (1.69 [1.10–2.61]), pancreas (2.63 [1.45–4.79]), lung (1.51 [1.14–2.00]), uterus (1.93 [1.06–3.51]) and bladder cancers (6.06 [2.49–14.74]) with FH of the concordant cancer were associated with an increased risk compared to those without FH. Our findings suggest that having FH of cancer is associated with an increased risk of several concordant cancer incidences in an Asian population. Enquiring about FH of several types of cancer may be important in identifying groups at high‐risk of those cancers.
Various presentations of preeclampsia at tertiary care hospital of Sindh: A Cross-Sectional Study.

BACKGROUND Preeclampsia is the multi-systemic hypertensive pregnancy disorder accompanied by proteinuria. OBJECTIVES To determine the frequency of different presentations of preeclampsia in tertiary care hospital and find out its risk factors. MATERIALS AND METHODS Present study was hospital based cross-sectional study and conducted from 1st August 2015 to 31st July 2016 in Gynaecology and Obstetrics department, Liaquat University of medical and health sciences (LUMHS), Hyderabad after ethical approval. A total of 112 pre-eclamptic women were enrolled during the study period by non-probability consecutive sampling. Patients were divided on the basis of their presentations into mild preeclampsia, severe preeclampsia, antepartum eclampsia, intrapartum eclampsia, HELLP syndrome, postpartum preeclampsia, postpartum eclampsia and atypical preeclampsia/eclampsia. All the socio-demographic factors and clinical variables were noted. Frequency and percentage were calculated for categorical variable and mean/standard deviation (SD) for continuous variables. RESULTS Of the 112 preeclamptic women, 54.5% admitted with antepartum eclampsia, 12.5% with severe preeclampsia, 8.9% with atypical preeclampsia/eclampsia, 8% with mild preeclampsia, 8% with postpartum eclampsia, 3.6% with HELLP syndrome, 2.7% with intrapartum eclampsia and 1.8% with postpartum preeclampsia. Over all, majority of the patients were primigravida (57%), had gestational age >34 weeks at presentation (58.9%) and <7 antenatal visits (88.3%) during their pregnancy. Over all 17.8% had previous bad obstetrical event, 11.6% had previous history of preeclampsia and 64.3% had consanguineous marriages. CONCLUSION Different presentations of preeclampsia may help obstetricians to rule out high risk pregnancies and provide antenatal care to patients earlier to prevent complications to both mother and fetus.
A Novel G Protein–Biased Agonist at the δ Opioid Receptor with Analgesic Efficacy in Models of Chronic Pain

Agonists at the δ opioid receptor are known to be potent antihyperalgesics in chronic pain models and effective in models of anxiety and depression. However, some δ opioid agonists have proconvulsant properties while tolerance to the therapeutic effects can develop. Previous evidence indicates that different agonists acting at the δ opioid receptor differentially engage signaling and regulatory pathways with significant effects on behavioral outcomes. As such, interest is now growing in the development of biased agonists as a potential means to target specific signaling pathways and potentially improve the therapeutic profile of δ opioid agonists. Here, we report on PN6047 (3-[[4-(dimethylcarbamoyl)phenyl]-[1-(thiazol-5-ylmethyl)-4-piperidylidene]methyl]benzamide), a novel G protein–biased and selective δ opioid agonist. In cell-based assays, PN6047 fully engages G protein signaling but is a partial agonist in both the arrestin recruitment and internalization assays. PN6047 is effective in rodent models of chronic pain but shows no detectable analgesic tolerance following prolonged treatment. In addition, PN6047 exhibited antidepressant-like activity in the forced swim test, and importantly, the drug had no effect on chemically induced seizures. PN6047 did not exhibit reward-like properties in the conditioned place preference test or induce respiratory depression. Thus, δ opioid ligands with limited arrestin signaling such as PN6047 may be therapeutically beneficial in the treatment of chronic pain states. SIGNIFICANCE STATEMENT PN6047 (3-[[4-(dimethylcarbamoyl)phenyl]-[1-(thiazol-5-ylmethyl)-4-piperidylidene]methyl]benzamide) is a selective, G protein–biased δ opioid agonist with efficacy in preclinical models of chronic pain. No analgesic tolerance was observed after prolonged treatment, and PN6047 does not display proconvulsant activity or other opioid-mediated adverse effects. Our data suggest that δ opioid ligands with limited arrestin signaling will be beneficial in the treatment of chronic pain.
Cerebrospinal Fluid Changes in the Renin-Angiotensin System in Alzheimer's Disease.

Observations in autopsied brain tissue indicate that overactivation of the classical renin-angiotensin system (cRAS) and underactivity within regulatory RAS pathways (rRAS) are associated with pathology in Alzheimer's disease (AD). The primary aim of this study was to investigate whether cerebrospinal fluid (CSF) markers of RAS are altered in AD in relation to established CSF markers of disease pathology (lower Aβ42 and elevated tau) and CSF markers of capillary dysfunction. We studied 40 controls and 40 AD cases grouped according to a biomarker profile (i.e., AD cases t-tau>400 pg/mL, pTau >60 pg/mL, and Aβ42 <550 pg/mL). Angiotensin-II converting enyme-1 (ACE1) and ACE2 enzyme activity was measured using fluorogenic peptide substrates; sPDGFRβ and albumin level by sandwich ELISA and angiotensin-I (Ang-I), Ang-II, and Ang-(1-7) by direct ELISA. CSF Aβ42, total, and phosphorylated tau levels were previously measured by INNOTEST sandwich ELISA. CSF ACE1 activity was significantly elevated in AD (p = 0.008) and positively correlated with ACE2 in AD (r = 0.420, p = 0.007). CSF ACE1 weakly correlated with t-tau (r = 0.294, p = 0.066) and p-tau (r = 0.329, p = 0.038) but not with Aβ42 in the controls but not in AD. ACE1 correlated positively with sPDGFRβ (r = 0.426, p = 0.007), a marker of pericyte injury, and ACE2 correlated positively with albumin (r = 0.422, p = 0.008), a marker of blood-brain barrier integrity. CSF Ang-I, Ang-II, and Ang-(1-7) levels were unchanged in AD. This cross-sectional CSF study indicates RAS dysfunction in relation to capillary damage in AD.
Effects of platelet-rich plasma on the clinical outcomes and cartilage thickness in patients with knee osteoarthritis.

BACKGROUND The interest in biological treatments that have the potential to modify cartilage biology has gradually increased in recent years. OBJECTIVE The aim of our study was to investigate the effects of intra-articular platelet-rich plasma (IA-PRP) injections on the femoral cartilage thickness, pain, functional status, and quality of life of patients with knee osteoarthritis. METHODS A total of 71 patients (109 knees) with knee osteoarthritis who were administered IA-PRP injections twice with two-week intervals were included in this study. The resting and activity pain values measured using a Visual Analogue Scale (VAS), the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), and the Lequesne index and the quality of life scores measured using Short Form-36 (SF-36) were recorded at the baseline and 1-month, 3-month, and 6-month follow ups. The femoral cartilage thickness was measured via ultrasonography before treatment, and at 3-month and 6-month follow ups. Obtained results were analyzed by the Wilcoxon signed rank test. RESULTS The mean age of the patients was 47.4 ± 10.4 years old. The resting and activity pain scores were significantly decreased at 1-month, 3-month and 6-month follow ups when compared to the pre-injection values (p< 0.05). Significant reductions were found in the Lequesne index and WOMAC pain, stiffness, and function scores at 1, 3, and 6 months (p< 0.05), while a significant increase was detected in the third month scores when compared to the first month. Significant improvements were determined in the physical functioning, physical role, pain, general health, and emotional role sub-scores during the 6-month period (p< 0.05). However, there was no significant difference with regard to the cartilage thickness at the follow ups (p> 0.05). CONCLUSIONS The results of our study indicated that the IA-PRP injections improved the pain, stiffness, physical functioning, and quality of life of knee osteoarthritis patients; however, they did not seem to affect the cartilage thickness during the 6-month follow up period.
Device and method matter: A critical evaluation of eccentric hamstring muscle strength assessments

Equivocal findings exist on isokinetic and Nordic hamstring exercise testing of eccentric hamstring strength capacity. Here, we propose a critical comparison of the mechanical output of hamstring muscles as assessed with either a dynamometer (IKD) or a Nordic hamstring device (NHD). Twenty‐five volunteers (26 ± 3 years) took part in a counterbalanced repeated‐measures protocol on both devices. Eccentric peak torque, work, angle of peak torque, bilateral strength ratios, and electromyography activity of the biceps femoris long head, semitendinosus and gastrocnemius muscles were assessed. There was a very poor correlation in eccentric peak torque between the devices (r < 0.58), with a systematic and proportional bias toward lower torque values on the IKD (~28%) and a high typical error (~19%) in IKD and NHD measurements comparison. Furthermore, participants performed a higher total eccentric work on IKD, reached peak torques at greater knee extension angles, and showed a greater side‐to‐side strength difference compared to the Nordic hamstring exercise. Gastrocnemius muscle activity was lower during the Nordic hamstring exercise. Reliability was low for work on NHD and for angle of peak torque and bilateral strength ratios on either device. We conclude that the evaluation of eccentric knee flexor strength depends on the testing conditions and even under standardized procedures, the IKD and NHD measure a different trait. Both tests have limitations in terms of assessing strength differences within an individual, and measurements of the angle of peak torque or side‐to‐side differences in eccentric knee flexor strength revealed low reliability and should be considered with caution.
Economic Status, Family Dependence, and Health Outcomes of Older People in Western Rural China

ABSTRACT There is a deficiency in empirical knowledge on the physical and mental health of lower-income older people with weak family support in western rural China. To address this research gap, this article uses the data from the 2014 China Longitudinal Aging Social Survey to analyze the disadvantaged situation of older people in western rural China through a regional comparative analysis. Our sample consisted of 7,138 older adults aged 60 or older in eastern and western, rural and urban China. We find that lower personal income is significantly associated with poor physical and mental health. Economic support from families means more for older people when they have a disability related to activities of daily living in western rural China. Fostering stronger family support networks might improve the mental health status of older people in western rural China. Our study suggests a broader scope for the state to play a greater role in economic empowerment and in the development of policies to effectively meet the present and future needs of older people in western rural China or other countries with an imbalance in the distribution of the aging population and welfare resources.
Positive Attitudes and Therapeutic Misconception Around Hypothetical Clinical Trial Participation in the Huntington’s Disease Community

Background: New therapies that could modify the disease course of Huntington’s disease (HD) are entering clinical trials. However, conceptions about clinical research from the HD community are unknown. This knowledge could help inform patient-clinician discussions surrounding clinical trial participation. Objective: The purpose of this study was to assess clinical trial attitudes and understanding in the HD community. Methods: We developed a survey incorporating two measures of trial understanding and attitudes and the impact of therapeutic route of administration on hypothetical trial participation. The survey was distributed via emails, flyers, and social media through HD-related organizations. Results: There were 73 responses. Individuals self-reported as clinically diagnosed with HD, gene positive but asymptomatic, or primary caregivers. Respondents viewed clinical trials positively and generally viewed trials as safe. Individuals with prior HD-related research experience were less likely to have negative expectations about trials than those without research experience (p = 0.002), and women had higher information needs than men (p = 0.001). Individuals with HD were more likely than the other groups to experience therapeutic misconception (p = 0.002). All respondents were able to appraise risks and benefits of research but exhibited optimism about trial outcomes. Willingness to participate was highest when the route of administration was minimally invasive. Conclusions: While the HD community views clinical trials positively, patients with HD are at high risk for therapeutic misconception and all groups are optimistic about trial outcomes. Limitations of this study include a small sample that may be inclined to view research positively given past trial participation and interest in participating in HD surveys. However, the findings from this study can be used to strengthen informed consent during HD clinical trial recruitment.
Motivations to Pursue Physical Therapy Residency Training: A Q-Methodology Study of Stakeholder Perspectives.

BACKGROUND Residency training is recognized as a valuable form of professional development and pathway to specialization. Currently residency is voluntary for physical therapists, with less than 12 percent of DPT students choosing to apply upon graduation. Motivations that drive the decision to pursue residency are currently unknown, as is the extent of similarity and difference in perspective among various stakeholders. OBJECTIVE The purpose of this study was to identify the dominant perspectives on motivations to pursue residency held by various stakeholders. DESIGN This study was conducted using Q Methodology, which incorporates aspects of quantitative and qualitative techniques to the examination of human subjectivity. METHODS Program directors, faculty, and current residents from all accredited physical therapy residency programs were invited to complete a forced-choice sorting activity where potential motivations for residency were sorted by perceived level of importance. Principal component analysis was used to identify dominant perspectives, which were interpreted based on emergent themes in the cluster of motivations identified as most important. RESULTS Four dominant perspectives were identified: (1) desire to provide better patient care, (2) preparation for specialty practice, (3) fast track to expert practice, and (4) career advancement. These perspectives provided context and utility to 2 broad meta-motivations, improved clinical reasoning and receiving mentoring. Both within- and between-group differences among stakeholders were identified. However, subsets from each role-group population were found to share similar perspectives. LIMITATIONS Results from this study may not apply to potential residents in all specialty areas and the implications of having a particular perspective are unknown. CONCLUSIONS Identification of the dominant perspective on motivations for pursuing residency may aid in promoting participation, program development, matching residents to programs and mentors, and future research.
