Understanding Baseline Concussion Testing: A Resource for School Nurses as Members of Concussion Management Teams.

Sports-related concussions (SRCs) are not uncommon among teen athletes. School nurses are in an ideal position to care for athletes affected with SRCs. However, evidence suggests there is a lack of knowledge regarding concussion management, use of baseline concussion testing, and active involvement on concussion management teams among school nurses. This article briefly examines the use of baseline concussion testing as a tool for assessing and managing the student athlete suffering from an SRC. The role of the school nurse on concussion management teams will also be explored. As active members of concussion management teams, working closely with athletic trainers, coaches, school administration, and local medical providers, school nurses have the opportunity to evaluate for return to learn and play, ultimately improving outcomes of student athletes suffering from SRCs.

Antibody Status, Disease History, and Incidence of SARS-CoV-2 Infection Among Patients on Chronic Dialysis.

BACKGROUND: Although reinfection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is rare among individuals with few coronavirus disease 2019 (COVID-19) risk factors, the ability of naturally acquired immunity to prevent reinfection among patients with ESKD is not known. METHODS: This prospective study was conducted among adults with ESKD treated with in-center hemodialysis (ICHD) in the United States. Exposure was ascribed on the basis of the presence or absence of IgG against SARS-CoV-2 at baseline, and separately, a history of documented COVID-19 before study entry. Outcomes were assessed after an infection-free period, and were any SARS-CoV-2 infection (i.e., detected by protocolized PCR tests or during routine clinical surveillance), and clinically manifest COVID-19 (consisting of only the latter). RESULTS: Of 2337 consented participants who met study inclusion criteria, 9.5% were anti-SARS-CoV-2 IgG positive at baseline; 3.6% had a history of COVID-19. Over 6679 patient-months of follow-up, 263 participants had evidence of any SARS-CoV-2 infection, including 141 who had clinically manifest COVID-19. Presence of anti-SARS-CoV-2 IgG (versus its absence) at baseline was associated with lower risk of any SARS-CoV-2 infection (incidence rate ratio, 0.55; 95% confidence interval, 0.32 to 0.95) and clinically manifest COVID-19 0.21 (95% confidence interval, 0.07 to 0.67). CONCLUSION: Among patients with ESKD, naturally acquired anti-SARS-CoV-2 IgG positivity is associated with a 45% lower risk of subsequent SARS-CoV-2 infection, and a 79% lower risk of clinically manifest COVID-19. Because natural immunity is incomplete, patients with ESKD should be prioritized for SARS-CoV-2 vaccination, independent of their COVID-19 disease history.

Effectiveness of a treadmill-based aerobic exercise intervention on pain, daily functioning, and quality of life in women with primary dysmenorrhea: A randomized controlled trial.

OBJECTIVE: To evaluate the effectiveness of a treadmill-based aerobic exercise intervention on pain and associated symptoms of primary dysmenorrhea. METHODS: Seventy women with primary dysmenorrhea were included in the study. The experimental group underwent supervised aerobic training for 4 weeks followed by unsupervised home exercise for the next 6 months. The control group continued usual care. The primary outcome was pain. Secondary outcomes included quality of life (QoL), daily functioning, and sleep. RESULTS: After the 4-week training, compared to the control group exercise significantly improved primary outcomes pain quality (mean difference (MD) -1.9, 95% CI 3.8 to -0.04, p < .05), and intensity (MD -4.7, 95% CI -9.3 to -0.09, p < .05), but not present pain. Significant effects were also reported for pain interference (MD -1.7, 95% CI -3.4 to -0.02, p < .05) at 4 weeks; the other outcomes did not significantly differ between groups at this time. During the follow-up period of 7-months, the effect on pain improved to 22 mm (95% CI 18 to 25). Significant benefits of exercise were maintained up to 7-months for present pain, QoL and daily functioning. CONCLUSION: Exercise has significant effects on primary dysmenorrhea-related pain, QoL and function. TRIAL REGISTRATION: ACTRN12613001195741.

Detection and Characterization of Salmonella spp. in Raw Commingled Bulk Tank Milk from Dairies in Pennsylvania.

A microbiological survey was conducted to determine the presence of Salmonella spp. in raw commingled bulk tank milk (BTM) collected from the Pennsylvania dairies intended for pasteurization. The survey found 8.1% (10/123) of samples positive for Salmonella. Salmonella Cerro was the predominant serovar and genetic analysis of the Salmonella Cerro showed the existence of diverse yet closely related genotypes. Antibiotic susceptibility testing conducted on all isolates showed pan-susceptible pattern against 15 drugs covering 9 drug classes. The study helped determine the presence of Salmonella spp. in the commingled BTM, antibiotic susceptibility patterns, and serovars along with genotypic diversity among the predominant serovar, Salmonella Cerro.

Detection of Brucella canis infection in dogs by blood culture and bacterial identification using matrix-assisted laser desorption/ionization time-of-flight mass spectrometry.

Brucella canis was recovered from dogs that were canine brucellosis suspect by blood culture using a modified lysis method. Organism identity was established by matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS). The instrument-provided security library identified the isolates as Brucella species. The isolates were further identified as B. canis with the help of phenotypic and genotypic characteristics. The mass spectral profiles from characterized B. canis isolates, when added to the MALDI-TOF MS standard reference library, allowed successful presumptive identification of B. canis.

Evaluation of Three Bacterial Identification Systems for Species Identification of Bacteria Isolated from Bovine Mastitis and Bulk Tank Milk Samples.

A study was conducted to evaluate Sensititre® Automated Reading and Incubation System 2x System (ARIS), API® (API), and Bruker MALDI-TOF MS (MALDI) bacterial species identification systems using 132 diverse bacterial isolates from bovine milk samples and bulk tank milk received at the Penn State Animal Diagnostic Laboratory. The results were compared with 16S rRNA gene sequence analysis, which served as the reference method for species identification. The ARIS, API, and MALDI identified 0%, 40%, and 33.4% of species classified as Gram-positive rod isolates belonging to genera Arthrobacter, Bacillus, Brachybacterium, Brevibacterium, and Corynebacterium, respectively. It was observed that 76.5%, 93.9%, and 96.9% of catalase-negative, Gram-positive cocci (n = 33; Aerococcus, Enterococcus, Lactococcus, Streptococcus) were correctly identified to the species level by ARIS, API, and MALDI, respectively, while 33.4%, 84.5%, and 97.7% of catalase-positive, Gram-positive cocci (n = 45; Kocuria, Staphylococcus) were correctly identified to their species by ARIS, API, and MALDI, respectively. A total of 48 isolates (Acinetobacter, Citrobacter, Enterobacter, Escherichia, Klebsiella, Pantoea, Pasteurella, Providencia, Pseduomonas, Serratia) of Gram-negative bacteria were examined, of which 85.4%, 93.7%, and 95.8% of the isolates were correctly identified to the species level by ARIS, API, and MALDI, respectively. In our laboratory, the MALDI had the least costs associated with consumables and reagents compared to ARIS, API, and 16S rRNA identification methods. Identification of bacterial species was accomplished in <2 h using MALDI and 24 h for ARIS, API, and 16S rRNA identification systems.

General Practitioners providing obstetric care in New Zealand. What differentiates GPs who continue to deliver babies?

AIM To identify factors that have enabled some New Zealand general practitioner obstetricians (GPOs) to continue providing maternity care and factors implicated in decisions to withdraw from maternity care. METHOD Semi-structured interviews and one focus group (n = 3) were conducted with 23 current and former GPOs. Interviews were transcribed and analysed thematically. RESULTS Current and former GPOs practiced maternity care because they enjoyed being involved in the birth process and delivery suite environment. Their maternity practice was framed by a philosophy of lifelong continuity of care for patients. CONCLUSION GPOs still practicing in New Zealand do so because they find maternity care highly rewarding despite their perceptions that the current maternity care model is incompatible with general practice. They have often developed local solutions that support their practice, particularly around shared care arrangements.

The Validity of a Brief Risk Assessment Tool for Predicting Suicidal Behavior in Veterans Utilizing VHA Mental Health Care.

Suicide risk among military veterans is an important and ongoing concern. The Veterans Administration (VA) mandates suicide risk screening of all veterans seen for mental health issues, but little is known about the effectiveness of this screening. A retrospective chart review to examine all suicide risk screens at VA San Diego between October and December 2012 (n = 3,365) was conducted to assess whether results were associated with suicidal behavior over the subsequent 12 months. Patients judged to be at increased risk for suicide were 3 to 16 times more likely to attempt suicide and 7 to 25 times more likely to engage in self-directed violence over the next 12 months compared with others. The screening tool may be a useful addition to clinical practice.

Financial Concerns About Participation in Clinical Trials Among Patients With Cancer.

PURPOSE: The decision to enroll in a clinical trial is complex given the uncertain risks and benefits of new approaches. Many patients also have financial concerns. We sought to characterize the association between financial concerns and the quality of decision making about clinical trials. METHODS: We conducted a secondary data analysis of a randomized trial of a Web-based educational tool (Preparatory Education About Clinical Trials) designed to improve the preparation of patients with cancer for making decisions about clinical trial enrollment. Patients completed a baseline questionnaire that included three questions related to financial concerns (five-point Likert scales): "How much of a burden on you is the cost of your medical care?," "I'm afraid that my health insurance won't pay for a clinical trial," and "I'm worried that I wouldn't be able to afford the costs of treatment on a clinical trial." Results were summed, with higher scores indicating greater concerns. We used multiple linear regressions to measure the association between concerns and self-reported measures of self-efficacy, preparation for decision making, distress, and decisional conflict in separate models, controlling for sociodemographic characteristics. RESULTS: One thousand two hundred eleven patients completed at least one financial concern question. Of these, 27% were 65 years or older, 58% were female, and 24% had a high school education or less. Greater financial concern was associated with lower self-efficacy and preparation for decision making, as well as with greater decisional conflict and distress, even after adjustment for age, race, sex, education, employment, and hospital location (P < .001 for all models). CONCLUSION: Financial concerns are associated with several psychological constructs that may negatively influence decision quality regarding clinical trials. Greater attention to patients' financial needs and concerns may reduce distress and improve patient decision making.

Randomized Trial of a Web-Based Intervention to Address Barriers to Clinical Trials.

PURPOSE: Lack of knowledge and negative attitudes have been identified as barriers to participation in clinical trials by patients with cancer. We developed Preparatory Education About Clinical Trials (PRE-ACT), a theory-guided, Web-based, interactive computer program, to deliver tailored video educational content to patients in an effort to overcome barriers to considering clinical trials as a treatment option. PATIENTS AND METHODS: A prospective, randomized clinical trial compared PRE-ACT with a control condition that provided general clinical trials information produced by the National Cancer Institute (NCI) in text format. One thousand two hundred fifty-five patients with cancer were randomly allocated before their initial visit with an oncologist to PRE-ACT (n = 623) or control (n = 632). PRE-ACT had three main components: assessment of clinical trials knowledge and attitudinal barriers, values assessment with clarification back to patients, and provision of a video library tailored to address each patient's barriers. Outcomes included knowledge and attitudes and preparation for decision making about clinical trials. RESULTS: Both PRE-ACT and control interventions improved knowledge and attitudes (all P < .001) compared with baseline. Patients randomly allocated to PRE-ACT showed a significantly greater increase in knowledge (P < .001) and a significantly greater decrease in attitudinal barriers (P < .001) than did their control (text-only) counterparts. Participants in both arms significantly increased their preparedness to consider clinical trials (P < .001), and there was a trend favoring the PRE-ACT group (P < .09). PRE-ACT was also associated with greater patient satisfaction than was NCI text alone. CONCLUSION: These data show that patient education before the first oncologist visit improves knowledge, attitudes, and preparation for decision making about clinical trials. Both text and tailored video were effective. The PRE-ACT interactive video program was more effective than NCI text in improving knowledge and reducing attitudinal barriers.

General practice registrars' views on maternity care in general practice in New Zealand.

INTRODUCTION: The number of general practitioners (GPs) providing maternity care in New Zealand has declined dramatically since legislative changes of the 1990s. The Ministry of Health wants GPs to provide maternity care again. AIM: To investigate New Zealand general practice registrars' perspectives on GPs' role in maternity care; specifically, whether maternity services should be provided by GPs, registrars' preparedness to provide such services, and training opportunities available or required to achieve this. METHODS: An anonymous online questionnaire was distributed to all registrars enrolled in The Royal New Zealand College of General Practitioners' (RNZCGP's) General Practice Education Programme (GPEP) in 2012, via their online learning platform OWL. RESULTS: 165 of the 643 general practice registrars responded (25.7% response rate). Most (95%) believe that GPs interested and trained in maternity care should consider providing antenatal, postnatal or shared care with midwives, and 95% believe women should be able to access maternity care from their general practice. When practising as a GP, 90% would consider providing antenatal and postnatal care, 47.3% shared care, and 4.3% full pregnancy care. Professional factors including training and adequate funding were most important when considering providing maternity care as a GP. DISCUSSION: Ninety-five percent of general practice registrars who responded to our survey believe that GPs should provide some maternity services, and about 90% would consider providing maternity care in their future practice. Addressing professional issues of training, support and funding are essential if more GPs are to participate in maternity care in New Zealand.

Menstrual pain and quality of life in women with primary dysmenorrhea: Rationale, design, and interventions of a randomized controlled trial of effects of a treadmill-based exercise intervention.

Dysmenorrhea in the absence of pelvic abnormality is termed primary dysmenorrhea (PD). The health burden and social and economic costs of PD are high as it is reported to be the leading cause of recurrent absenteeism from school or work in adolescent girls and young adults. The belief that exercise works for relieving symptoms in women with PD is based on anecdotal evidence and non-experimental studies. There is very limited evidence from randomized controlled trials (RCTs) to support the use of exercise to reduce the intensity of menstrual pain. The objective of this study is to evaluate the effectiveness of exercise to reduce intensity of pain and improve quality of life in women with PD. We describe the study design of a single-blind (assessor), prospective, two-arm RCT, and the participant characteristics of the 70 women recruited in the age-group 18 to 43 years. The primary outcome of the study is pain intensity. The secondary outcomes of the study are quality of life, functional limitation, sleep, global improvement with treatment, and protocol adherence. The outcomes assessments are done at first menstrual period (baseline, Week 0), 2nd menstrual period (Week 4) and at two additional time points (Week 16 and Week 28) during the trial. The results of the study will provide physiotherapists, medical practitioners, and researchers as well as the women who have PD with new insights, knowledge, and evidence about the use of exercise to manage pain in women with PD.

Vigorous exercises in the management of primary dysmenorrhea: a feasibility study.

PURPOSE: To examine the feasibility of using an exercise intervention for reducing menstrual pain associated with primary dysmenorrhea (PD) and to obtain preliminary results to estimate the sample size for a future randomized controlled trial (RCT). METHODS: A quasi-experimental design was applied. Ten women 18-45 years with PD were included. The participants underwent vigorous aerobic training at the School of Physiotherapy on a treadmill three times a week for up to 4 weeks followed by aerobic training at home for up to 4 weeks. The feasibility measures were adherence to the intervention programme and intervention prescription, retention and safety. The short form McGill pain questionnaire was used to measure pain at first (T1), second (T2) and third (T3) menstrual cycles following trial entry. RESULTS: Overall adherence was 98%, with 100% adherence to clinic-based intervention and intervention prescription and 96% for home exercise programme. Retention rate was 100%. With respect to pain a large effect size was identified at T2 and T3. No adverse events reported. CONCLUSIONS: Results demonstrated that the intervention is applicable and feasible. In addition, the preliminary results show evidence of positive changes after the intervention. The intervention programme's effectiveness will be studied further, in a future RCT. Implications for Rehabilitation There is a lack of available evidence from randomized controlled trials regarding the use of exercise in alleviating the symptoms associated with primary dysmenorrhea (PD). The preliminary results of this study shows that exercises may be effective in reducing the pain associated with PD indicated by a large effect size. The preliminary findings from this study could also contribute significantly to PD management and introduce new practice opportunities for physiotherapists working in women's health.

Application of best practice approaches for designing decision support tools: the preparatory education about clinical trials (PRE-ACT) study.

OBJECTIVE: This article describes the rigorous development process and initial feedback of the PRE-ACT (Preparatory Education About Clinical Trials) web-based- intervention designed to improve preparation for decision making in cancer clinical trials. METHODS: The multi-step process included stakeholder input, formative research, user testing and feedback. Diverse teams (researchers, advocates and developers) participated including content refinement, identification of actors, and development of video scripts. Patient feedback was provided in the final production period and through a vanguard group (N=100) from the randomized trial. RESULTS: Patients/advocates confirmed barriers to cancer clinical trial participation, including lack of awareness and knowledge, fear of side effects, logistical concerns, and mistrust. Patients indicated they liked the tool's user-friendly nature, the organized and comprehensive presentation of the subject matter, and the clarity of the videos. CONCLUSION: The development process serves as an example of operationalizing best practice approaches and highlights the value of a multi-disciplinary team to develop a theory-based, sophisticated tool that patients found useful in their decision making process. Practice implications Best practice approaches can be addressed and are important to ensure evidence-based tools that are of value to patients and supports the usefulness of a process map in the development of e-health tools.

Knowledge, attitudes, and self-efficacy as predictors of preparedness for oncology clinical trials: a mediational model.

OBJECTIVE: This study used the Ottawa Decision Support Framework to evaluate a model examining associations between clinical trial knowledge, attitudinal barriers to participating in clinical trials, clinical trial self-efficacy, and clinical trial preparedness among 1256 cancer patients seen for their first outpatient consultation at a cancer center. As an exploratory aim, moderator effects for gender, race/ethnicity, education, and metastatic status on associations in the model were evaluated. METHODS: . Patients completed measures of cancer clinical trial knowledge, attitudinal barriers, self-efficacy, and preparedness. Structural equation modeling (SEM) was conducted to evaluate whether self-efficacy mediated the association between knowledge and barriers with preparedness. RESULTS: . The SEM explained 26% of the variance in cancer clinical trial preparedness. Self-efficacy mediated the associations between attitudinal barriers and preparedness, but self-efficacy did not mediate the knowledge-preparedness relationship. CONCLUSIONS: . Findings partially support the Ottawa Decision Support Framework and suggest that assessing patients' level of self-efficacy may be just as important as evaluating their knowledge and attitudes about cancer clinical trials.

"Tossing out the baby with the bath water": New Zealand general practitioners on maternity care.

A rapid decline in the number of general practitioners practicing obstetrics followed legislative changes in New Zealand during the early 1990s that changed the maternity care landscape. The resulting repositioning of maternity care professions has seen medical dominance give way to midwifery dominance in the maternity marketplace. Drawing on our research, we suggest that current and former general practitioner obstetricians harbor grievances relating to (1) the loss of obstetrics from the 'cradle to grave' philosophy of general practice, and (2) policies encouraging competition between maternity care providers. We argue that these perspectives represent truth games that are generated by the disciplinary blocks of the maternity care professions, and reveal the moral nature of the political economy of maternity care.

GP obstetricians' views of the model of maternity care in New Zealand.

BACKGROUND: The Lead Maternity Carer (LMC) model of maternity care, and independent midwifery practice, was introduced to New Zealand in the 1990s. The LMC midwife or general practitioner obstetrician (GPO) has clinical and budgetary responsibility for women's primary maternity care. AIMS: To determine views of practising GPOs and former GPOs about the LMC model of care, its impact on maternity care in general practice, and future of maternity care in general practice. METHODS: 10 GPOs and 13 former GPOs were interviewed: one focus group (n = 3), 20 semi-structured interviews. The qualitative data analysis program ATLAS.ti assisted thematic analysis. RESULTS: Participants thought the LMC model isolates the LMC - particularly concerning during intrapartum care, in rural practice, and covering 24-hour call; Is not compatible with or adequately funded for GP participation; Excludes the GP from caring for their pregnant patients. Participants would like a flexible, locally adaptable, adequately funded maternity model, supporting shared care. Some thought work-life balance and low GPO numbers could deter future GPs from maternity practice. Others felt with political will, support of universities, and Royal New Zealand College of General Practice and Royal Australian and New Zealand College of Obstetrics and Gynaecology, GPs could become more involved in maternity care again. CONCLUSIONS: Participants thought the LMC model isolates maternity practitioners, is incompatible with general practice and causes loss of continuity of general practice care. They support provision of maternity care in general practice; however, for more GPs to become involved, the LMC model needs review.

Prevalence of Salmonella cerro in laboratory-based submissions of cattle and comparison with human infections in Pennsylvania, 2005-2010.

The aim of this study was to identify Salmonella serotypes infecting cattle in Pennsylvania, to compare infection rates for the predominant serotype, Salmonella enterica serotype Cerro, with the infection rates for the same serotype in humans, and to study the clonal diversity and antimicrobial resistance for this serotype in cattle from 2005 to 2010. Clonal diversity among the selected isolates was studied using pulsed-field gel electrophoresis (PFGE) and repetitive (rep)-polymerase chain reaction (PCR). Salmonella Cerro showed the single largest increase as a cause of cattle infections over the study period. The proportional distribution of Salmonella Cerro serotype among laboratory-submitted Salmonella positive cases in cattle was 36.1% in the year 2010 compared to 14.3% in 2005. A simultaneous decrease in serotype Newport infections was also observed in cattle (25% in 2005, to 10.1% in 2010). Studies of clonal diversity for cattle and human isolates revealed a predominant PFGE type but showed some variability. All tested isolates (n = 60) were susceptible to sulfamethoxazole-trimethoprim, but 2% of cattle isolates (n = 1/50) and 20% of human isolates (n = 2/10) showed resistance to tetracycline and sulfisoxazole. One human isolate showed additional resistance to ampicillin and gentamicin. This study suggests an increase in Salmonella Cerro infections in the cattle population and a decrease in Salmonella Newport infections. The increase in Cerro infections appears to be restricted to the cattle population, but occasional human infections occur.

Final-year medical students' perceptions of maternity care in general practice.

AIMS: To investigate the perceptions of final year medical students' (known as trainee interns or TIs) at the University of Otago about maternity care in general practice, their possible future roles in general practice maternity care, and factors influencing this. METHODS: An anonymous questionnaire using the online programme SurveyMonkey was emailed to the 227 Otago University TIs. Results were analysed using SurveyMonkey statistical analysis. RESULTS: The response rate was 50.7%. About 90% of the TIs thought GPs should provide antenatal and postnatal care, 80.7% supported shared care and 55.7% thought GPs should provide full maternity care if interested and trained to do so. Almost 80% thought women should have access to full maternity care in general practice. If practicing as a GP 90% or more of respondents would consider providing prenatal, early pregnancy, antenatal, postnatal care, or shared care and 64.0% full maternity care. Of the 29 TIs (25.2%) who had seen a GP practicing full maternity care 82.8% would consider offering this level of care if practicing as a GP. And 68.3% of the 65 TIs interested in a rural general practice career would consider providing full maternity care. Issues of training, professional support, funding and continuity of care for patients were important factors in contemplating providing full maternity care. CONCLUSIONS: TIs are interested in providing a wide range of maternity services if practicing as a GP. Many professional and lifestyle issues could influence our future doctors when deciding whether to practice maternity care in general practice.
