Web-Based Asynchronous Tool to Facilitate Communication Between Primary Care Providers and Cancer Specialists: Pragmatic Randomized Controlled Trial.

BACKGROUND: Cancer poses a significant global health burden. With advances in screening and treatment, there are now a growing number of cancer survivors with complex needs, requiring the involvement of multiple health care providers. Previous studies have identified problems related to communication and care coordination between primary care providers (PCPs) and cancer specialists. OBJECTIVE: This study aimed to examine whether a web- and text-based asynchronous system (eOncoNote) could facilitate communication between PCPs and cancer specialists (oncologists and oncology nurses) to improve patient-reported continuity of care among patients receiving treatment or posttreatment survivorship care. METHODS: In this pragmatic randomized controlled trial, a total of 173 patients were randomly assigned to either the intervention group (eOncoNote plus usual methods of communication between PCPs and cancer specialists) or a control group (usual communication only), including 104 (60.1%) patients in the survivorship phase (breast and colorectal cancer) and 69 (39.9%) patients in the treatment phase (breast and prostate cancer). The primary outcome was patient-reported team and cross-boundary continuity (Nijmegen Continuity Questionnaire). Secondary outcome measures included the Generalized Anxiety Disorder Screener (GAD-7), Patient Health Questionnaire on Major Depression, and Picker Patient Experience Questionnaire. Patients completed the questionnaires at baseline and at 2 points following randomization. Patients in the treatment phase completed follow-up questionnaires at 1 month and at either 4 months (patients with prostate cancer) or 6 months following randomization (patients with breast cancer). Patients in the survivorship phase completed follow-up questionnaires at 6 months and at 12 months following randomization. RESULTS: The results did not show an intervention effect on the primary outcome of team and cross-boundary continuity of care or on the secondary outcomes of depression and patient experience with their health care. However, there was an intervention effect on anxiety. In the treatment phase, there was a statistically significant difference in the change score from baseline to the 1-month follow-up for GAD-7 (mean difference -2.3; P=.03). In the survivorship phase, there was a statistically significant difference in the change score for GAD-7 between baseline and the 6-month follow-up (mean difference -1.7; P=.03) and between baseline and the 12-month follow-up (mean difference -2.4; P=.004). CONCLUSIONS: PCPs' and cancer specialists' access to eOncoNote is not significantly associated with patient-reported continuity of care. However, PCPs' and cancer specialists' access to the eOncoNote intervention may be a factor in reducing patient anxiety.

Cancer specialist perspectives on implementing an online communication system with primary care providers.

Context: The Canadian Team to Improve Community-Based Cancer Care along the Continuum (CanIMPACT) is a group of researchers, primary care providers (PCPs), cancer specialists, patients and caregivers working to improve cancer care coordination between PCPs and cancer specialists. Previous research by CanIMPACT and others has identified problems related to communication, coordination, and continuity of care. Objective: Describe findings from qualitative interviews with cancer specialists on implementation of an online communication system with PCPs. Study Design: Hybrid type I effectiveness-implementation study that included a qualitative research component and a pragmatic RCT. Setting: Ottawa Hospital Cancer Program and primary care practices in the Champlain region. Population Studied: Cancer specialists (nurses, medical and radiation oncologists, program administrators). Interviews conducted with 12 cancer specialists. Intervention: Cancer-specific adaptation of Champlain BASE™ eConsult, an online communication system for PCPs and cancer specialists called "eOncoNote". For patients receiving treatment for prostate or breast cancer, cancer specialists had an opportunity to participate in eOncoNote discussion with PCP for 4-6 months; for breast and colorectal cancer survivors, the eOncoNote discussion lasted for 1 year post discharge to the patient's PCP. Results: Cancer specialists described limited PCP involvement in cancer care while patients received active treatment, with one-way communication and notes being "sent into a vacuum". There was more communication with PCPs regarding patients with metastatic disease, comorbid conditions, after patients have completed treatment, or during palliative care. Patients and caregivers play a critical role in coordinating cancer care, helping to facilitate coordination. Lack of access to the same electronic medical record (EMR) among healthcare providers poses a barrier to cancer care coordination. eOncoNote had the potential to be useful tool but it was not used extensively. Conclusions: Accessing eOncoNote as a separate system was challenging to incorporate into the workflow, and cancer specialists highlighted the need for integration with their EMR. eOncoNote did not affect information sharing with PCPs, as there was limited uptake within primary care.

The Genetic Basis of Strokes in Pediatric Populations and Insight into New Therapeutic Options.

Strokes within pediatric populations are considered to be the 10th leading cause of death in the United States of America, with over half of such events occurring in children younger than one year of life. The multifactorial etiopathology that has an influence on stroke development and occurrence signify the importance of the timely recognition of both modifiable and non-modifiable factors for adequate diagnostic and treatment approaches. The early recognition of a stroke and stroke risk in children has the potential to advance the application of neuroprotective, thrombolytic, and antithrombotic interventions and rehabilitation strategies to the earliest possible timepoints after the onset of a stroke, improving the outcomes and quality of life for affected children and their families. The recent development of molecular genetic methods has greatly facilitated the analysis and diagnosis of single-gene disorders. In this review, the most significant single gene disorders associated with pediatric stroke are presented, along with specific therapeutic options whenever they exist. Besides monogenic disorders that may present with stroke as a first symptom, genetic polymorphisms may contribute to the risk of pediatric and perinatal stroke. The most frequently studied genetic risk factors are several common polymorphisms in genes associated with thrombophilia; these genes code for proteins that are part of the coagulation cascade, fibrolysis, homocystein metabolism, lipid metabolism, or platelets. Single polymorphism frequencies may not be sufficient to completely explain the stroke causality and an analysis of several genotype combinations is a more promising approach. The recent steps forward in our understanding of the disorders underlying strokes has given us a next generation of therapeutics and therapeutic targets by which to improve stroke survival, protect or rebuild neuronal connections in the brain, and enhance neural function. Advances in DNA sequencing and the development of new tools to correct human gene mutations have brought genetic analysis and gene therapy into the focus of investigations for new therapeutic options for stroke patients.

Genetic Aspects of Inflammation and Immune Response in Stroke.

Genetic determinants play important role in the complex processes of inflammation and immune response in stroke and could be studied in different ways. Inflammation and immunomodulation are associated with repair processes in ischemic stroke, and together with the concept of preconditioning are promising modes of stroke treatment. One of the important aspects to be considered in the recovery of patients after the stroke is a genetic predisposition, which has been studied extensively. Polymorphisms in a number of candidate genes, such as IL-6, BDNF, COX2, CYPC19, and GPIIIa could be associated with stroke outcome and recovery. Recent GWAS studies pointed to the variant in genesPATJ and LOC as new genetic markers of long term outcome. Epigenetic regulation of immune response in stroke is also important, with mechanisms of histone modifications, DNA methylation, and activity of non-coding RNAs. These complex processes are changing from acute phase over the repair to establishing homeostasis or to provoke exaggerated reaction and death. Pharmacogenetics and pharmacogenomics of stroke cures might also be evaluated in the context of immuno-inflammation and brain plasticity. Potential novel genetic treatment modalities are challenged but still in the early phase of the investigation.

Audit of community pharmacists' prescribing interventions: Quality assessment of a newly reimbursed service.

OBJECTIVES: To evaluate community pharmacists' reimbursed prescribing interventions (called pharmaceutical opinions/POs in Canada) by determining the types of drug-related problems (DRPs) identified; the type, quality, and clinical impact of recommendations made; and variation in recommendation quality across regions, pharmacy ownership type, and pharmacy size. DESIGN: Retrospective audit of randomly sampled service documentation records. SETTING: Community pharmacies in Ontario, Canada, 3 years after implementation of a government program that reimburses pharmacies for providing DRP-based POs to physicians. PARTICIPANTS: Thirty-six community pharmacies in 4 regions of Ontario. MAIN OUTCOME MEASURES: For each PO, 2 experienced clinical pharmacists independently, and then by consensus, determined the primary drug implicated and its therapeutic category, the type of DRP, and the type of prescriber recommendation. Each PO recommendation was assessed for clinical impact, evidence base, and overall quality. Chi-square analyses assessed the relationship between PO quality and pharmacy characteristics. RESULTS: Of 563 POs, 261 (46%) met reimbursement criteria for stating a DRP and prescriber recommendation. Among these eligible POs, systemic antiinfective (22%), alimentary tract and metabolism (19%), nervous system (15%), and cardiovascular (15%) drugs were most commonly identified in the DRP. Adverse drug reactions (which included drug interactions) were the most common type of DRP (42.5%), followed by "dose too high" (16%) and "needs additional therapy" (14%). Top recommendations were to change the drug (41%) and to decrease the dose (20%). The quality of the pharmacist's recommendation was judged to be good to excellent in 70% of the 261 eligible POs; quality was associated with region and ownership type. CONCLUSION: PO quality was suboptimal: the primary issue was failure to state a prescriber recommendation. Collaborative efforts are needed from community pharmacy stakeholders (schools of pharmacy, regulatory colleges, and continuing education providers) to help pharmacists enhance the quality of their POs, beginning with their clinical documentation skills.

Anxiety-related behavior in hyperhomocysteinemia induced by methionine nutritional overload in rats: role of the brain oxidative stress.

The aim of this study was to examine the effects of a methionine-enriched diet on anxiety-related behavior in rats and to determine the role of the brain oxidative status in these alterations. Adult male Wistar rats were fed from the 30th to 60th postnatal day with standard or methionine-enriched diet (double content comparing with standard diet: 7.7 g/kg). Rats were tested in open field and light-dark tests and afterwards oxidative status in the different brain regions were determined. Hyperhomocysteinemia induced by methionine-enriched diet in this study decreased the number of rearings, as well as the time that these animals spent in the center of the open field, but increased index of thigmotaxy. Oxidative status was selectively altered in the examined regions. Lipid peroxidation was significantly increased in the cortex and nc. caudatus of rats developing hyperhomocysteinemia, but unaltered in the hippocampus and thalamus. Based on the results of this research, it could be concluded that hyperhomocysteinemia induced by methionine nutritional overload increased anxiety-related behavior in rats. These proanxiogenic effects could be, at least in part, a consequence of oxidative stress in the rat brain.

The likelihood of detecting abnormal karyotypes in fetuses with a single major anomaly or "soft" marker on ultrasonographic scanning.

OBJECTIVE: Fetuses with abnormal karyotypes often exhibit distinctive ultrasonographic markers, including major anomalies and "soft" markers, indicating potential chromosomal issues. A crucial consideration arises when a single fetal anomaly is detected, raising the question of whether karyotyping is warranted, given the associated procedural risks. Our objective was to establish correlations between single fetal anomalies identified through ultrasound and chromosomal abnormalities. METHODS: A cross-sectional study analyzed the karyotype of 1493 fetuses and detected a single ultrasonographic anomaly over a 16-year period. Karyotyping was performed using the standard karyotype technique. Moreover, data regarding the type of anomaly detected ultrasonographically, karyotype results, and outcomes following interventions were collected. Among other methods, the use of positive likelihood ratios (LR+) was used to evaluate the diagnostic accuracy of ultrasound compared to karyotyping. RESULTS: In total, an aberrant karyotype was identified in 99 fetuses (6.6%). This was most commonly observed in cases involving a "soft" marker, occurring in 27 out of 218 fetuses (12.4%). The most frequently detected aberrant karyotype resulted from aneuploidies (80.6% of cases), notably trisomy 21 (50.5%). "Soft" markers predicted chromosomal issues (LR+ = 1.9; OR = 2.4), and isolated polyhydramnios (LR+ = 1.54; OR = 1.6) showed significance in predicting fetal chromosomal aberrations. CONCLUSION: When assessing the necessity for karyotyping in fetuses with single major anomalies or "soft" markers, it is crucial to consider individual risks for chromosomopathies, including the LR+ of the detected marker. In cases where fetuses exhibit isolated anomalies with a normal karyotype, additional diagnostic measures, such as molecular cytogenetic and molecular genetics techniques, may become necessary.

miRNAs as a Potential Biomarker in the COVID-19 Infection and Complications Course, Severity, and Outcome.

During the last three years, since the emergence of the COVID-19 pandemic, a significant number of scientific publications have focused on resolving susceptibility to the infection, as well as the course of the disease and potential long-term complications. COVID-19 is widely considered as a multisystem disease and a variety of socioeconomic, medical, and genetic/epigenetic factors may contribute to the disease severity and outcome. Furthermore, the SARS-COV-2 infection may trigger pathological processes and accelerate underlying conditions to clinical entities. The development of specific and sensitive biomarkers that are easy to obtain will allow for patient stratification, prevention, prognosis, and more individualized treatments for COVID-19. miRNAs are proposed as promising biomarkers for different aspects of COVID-19 disease (susceptibility, severity, complication course, outcome, and therapeutic possibilities). This review summarizes the most relevant findings concerning miRNA involvement in COVID-19 pathology. Additionally, the role of miRNAs in wide range of complications due to accompanied and/or underlying health conditions is discussed. The importance of understanding the functional relationships between different conditions, such as pregnancy, obesity, or neurological diseases, with COVID-19 is also highlighted.

Carcinogenic and human health risk assessment of children's and adults' exposure to toxic metal(oid)s from air PM10 in critical sites of the Republic of Serbia.

With global urbanization and industrialization, air pollution has become an inevitable problem. Among air pollutants, toxic metals bound to particulate matter (PM) have a high hazardous potential, contributing to the development of several diseases, including various types of cancer. Due to PM pollution, Serbia is considered to be among the most polluted countries in Europe. Therefore, the objective of the study was to assess and characterize the non-carcinogenic and carcinogenic risks of children's and adults' exposure to metal(oid)s (Pb, Cd, Ni, and As) bound to PM10 in five of the most polluted areas in the Republic of Serbia (Subotica, Smederevo, Bor, Valjevo, and Kraljevo). Non-carcinogenic (HQ and HI) and carcinogenic risk (CR) were calculated using USEPA methodology. Our results show that PM10 concentrations exceeded the annual limit of 40 µg/m3 at four out of five monitoring sites (ranging from 44.33 to 63.25 µg/m3). Results obtained from Bor monitoring station show that safe limits were exceeded for both children and adults, indicating an unacceptable risk (> 1) obtained for inhalation exposure to the As (HQ = 6.14) and Cd (HQ = 1.17), while total HI was 7.43, which characterized the risk as unacceptable. For the same station, the CR value was 1.44E-04 (> 1 × 10-4). In other sites, the risks were acceptable. The characterized risk from exposure to the toxic elements via PM10 in critical locations in Serbia contributes to improving air quality by requiring regulatory organs to take new actions and adopt new measures to reduce air pollution.

Implementation of a Web-Based Communication System for Primary Care Providers and Cancer Specialists.

Healthcare providers have reported challenges with coordinating care for patients with cancer. Digital technology tools have brought new possibilities for improving care coordination. A web- and text-based asynchronous system (eOncoNote) was implemented in Ottawa, Canada for cancer specialists and primary care providers (PCPs). This study aimed to examine PCPs' experiences of implementing eOncoNote and how access to the system influenced communication between PCPs and cancer specialists. As part of a larger study, we collected and analyzed system usage data and administered an end-of-discussion survey to understand the perceived value of using eOncoNote. eOncoNote data were analyzed for 76 shared patients (33 patients receiving treatment and 43 patients in the survivorship phase). Thirty-nine percent of the PCPs responded to the cancer specialist's initial eOncoNote message and nearly all of those sent only one message. Forty-five percent of the PCPs completed the survey. Most PCPs reported no additional benefits of using eOncoNote and emphasized the need for electronic medical record (EMR) integration. Over half of the PCPs indicated that eOncoNote could be a helpful service if they had questions about a patient. Future research should examine opportunities for EMR integration and whether additional interventions could support communication between PCPs and cancer specialists.

Patient and Healthcare Provider Perspectives on the Implementation of a Web-Based Clinical Communication System for Cancer: A Qualitative Study.

Previous research has identified communication and care coordination problems for patients with cancer. Healthcare providers (HCPs) have reported communication issues due to the incompatibility of electronic medical records (EMR) software and not being consistently copied on patient reports. We evaluated an asynchronous web-based communication system ("eOncoNote") for primary care providers and cancer specialists to improve cancer care coordination. The objectives were to examine patients' perceptions of the role of eOncoNote in their healthcare, and HCPs' experiences of implementing eOncoNote. Qualitative interviews were conducted with patients with breast and prostate cancer, primary care providers, and cancer specialists. Eighteen patients and fourteen HCPs participated. Six themes were identified from the patient interviews focusing on HCP and patient roles related to care coordination and patient awareness of communication among their HCPs. Four themes were identified from HCP interviews related to the context of care coordination and experience with eOncoNote. Both patients and HCPs described the important role patients and caregivers play in care coordination. The results show that patients were often unaware of the communication between their HCPs and assumed they were communicating. HCPs encountered challenges incorporating eOncoNote into their workflow.

Early Changes in Nitrate Uptake and Assimilation Under Drought in Relation to Transpiration.

Soil drying combined with nitrogen (N) deficiency poses a grave threat to agricultural crop production. The rate at which nitrate (NO3 -) is taken up depends partly on the uptake and transpiration of water. Rapid changes in nitrate assimilation, in contrast to other N forms, may serve as a component of the plant stress response to drought because nitrate assimilation may lead to changes in xylem pH. The modulation of xylem sap pH may be relevant for stomata regulation via the delivery of abscisic acid (ABA) to guard cells. In several factorial experiments, we investigated the interactions between nitrate and water availability on nitrate fate in the plant, as well as their possible implications for the early drought-stress response. We monitored the short-term response (2-6 days) of nitrate in biomass, transport to shoot and reduction in Pisum sativum, Hordeum vulgare, Vicia faba, and Nicotiana tabacum and correlated this with sap pH and transpiration rates (TRs). Cultivation on inorganic substrate ensured control over nutrient and water supply and prevented nodulation in legume species. NO3 - content in biomass decreased in most of the species under drought indicating significant decline in NO3 - uptake. Hordeum vulgare had the highest NO3 - concentrations in all organs even under drought and low NO3 - treatment. This species can likely respond much better to the combined adverse effects of low NO3 - and water scarcity. Nitrate reductase activity (NRA) was reduced in both roots and leaves of water deficient (WD) plants in all species except H. vulgare, presumably due to its high NO3 - contents. Further, transient reduction in NO3 - availability had no effect on sap pH. Therefore, it seems unlikely that NRA shifts from shoot root leading to the supposed alkalization of sap. We also did not observe any interactive effects of NO3 - and water deficiency on transpiration. Hence, as long as leaf NO3 - content remains stable, NO3 - availability in soil is not linked to short-term modulation of transpiration.

Nonsteroidal antiinflammatory drugs and risk of gastrointestinal bleeding among patients on hemodialysis.

BACKGROUND: Both use of nonsteroidal antiinflammatory drugs (NSAIDs) and chronic renal insufficiency are significant independent risk factors for gastrointestinal bleeding. OBJECTIVE: The aim of our study was to investigate whether regular use of NSAIDs further increases the risk of gastrointestinal bleeding among patients with end-stage renal insufficiency on hemodialysis. METHODS: This was a case-control study. Case and control patients were selected from the lists of patients on hemodialysis during the period of 4 months (n=650), at 3 secondary care general hospitals in Serbia. Cases (n=33) were chosen from the study population if they had experienced at least 1 episode of gastrointestinal bleeding during the last 3 years. For each case, at least 1 sex- and age-matched control patient (n=45) was randomly selected from the source population. RESULTS: Among patients on hemodialysis, NSAIDs users had approximately 3 times higher risk of developing gastrointestinal bleeding, than non-users (crude odds ratio = 3.29; 95% confidence interval [95% CI], 1.28-8.45). After adjustment for potential confounders (sex, age, use of erythropoietin or parenteral iron, frequency of NSAID use, smoking, drinking alcohol, heart failure, arterial hypertension, diabetes mellitus, chronic obstructive pulmonary disease, and use of anticoagulants, antiplatelet agents, beta-blockers, angiotensin-converting enzyme inhibitors or diuretics), the only significant association that remained was between gastrointestinal bleeding and use of NSAIDs (OR adjusted = 5.8; 95% CI, 1.3-26.9; p=0.024). CONCLUSION: There is a need for development of effective strategies to prevent gastrointestinal bleeding in patients on hemodialysis who use NSAIDs.

Prenatal Androgenization Induces Anxiety-Like Behavior in Female Rats, Associated with Reduction of Inhibitory Interneurons and Increased BDNF in Hippocampus and Cortex.

Anxiety is one of the most frequent psychiatric disorders. Despite the fact that most studies describe an anxiolytic effect of testosterone, hyperandrogenemia in mothers is assumed to be related to an increased risk of mood disorders in their offspring. An increasing body of scientific evidence suggests that an altered expression of interneuronal markers of the hippocampus may be the cause of anxiety. The aim of this study was to examine the influence of maternal hyperandrogenemia on behavioral parameters of anxiety-like behavior, neuropeptide Y (NPY) and parvalbumin (PV) expression in the hippocampus, and the level of the brain-derived neurotrophic factor (BDNF) in the hippocampus and cerebral cortex. Pregnant female Wistar albino rats were treated with testosterone undecanoate on the 20th day of gestation. Anxiety-like behavior in adult female offspring was evaluated by the elevated plus maze test and the open field. The number of PV and NPY immunoreactive cells in the hippocampus was determined immunohistochemically. The level of BDNF expression in the hippocampus and cerebral cortex was analyzed with the Western blot test. Prenatal hyperandrogenization increased anxiety-like behavior in female offspring and decreased expression of NPY+ and PV+ in the CA1 region of the hippocampus as compared to the control group. BDNF expression in the hippocampus and cerebral cortex of prenatally androgenized female offspring was significantly increased in comparison with the controls. Prenatal hyperandrogenization may be the cause of anxiety-like behavior in female offspring. Decrease in NPY and PV expression in the hippocampus may explain the possible mechanism of hyperandrogenization induced anxiety.

Contextual factors influencing the implementation of innovations in community-based primary health care: the experience of 12 Canadian research teams.

The objectives of this paper are to: (1) identify contextual factors such as policy that impacted the implementation of community-based primary health care (CBPHC) innovations among 12 Canadian research teams and (2) describe strategies used by the teams to address contextual factors influencing implementation of CBPHC innovations. In primary care settings, consideration of contextual factors when implementing change has been recognized as critically important to success. However, contextual factors are rarely recorded, analyzed or considered when implementing change. The lack of consideration of contextual factors has negative implications not only for successfully implementing primary health care (PHC) innovations, but also for their sustainability and scalability. For this evaluation, data collection was conducted using self-administered questionnaires and follow-up telephone interviews with team representatives. We used a combination of directed and conventional content analysis approaches to analyze the questionnaire and interview data. Representatives from all 12 teams completed the questionnaire and 11 teams participated in the interviews; 40 individuals participated in this evaluation. Four themes representing contextual factors that impacted the implementation of CBPHC innovations were identified: (I) diversity of jurisdictions (II) complexity of interactions and collaborations (III) policy, and (IV) the multifaceted nature of PHC. The teams used six strategies to address these contextual factors including: (1) conduct an environmental scan at the beginning (2) maintaining engagement among partners and stakeholders by encouraging open and inclusive communication; (3) contextualizing the innovation for different settings; (4) anticipating and addressing changes, delays, and the need for additional resources; (5) fostering a culture of research and innovation among partners and stakeholders; and (6) ensuring information about the innovation is widely available. Implementing CBPHC innovations across jurisdictions is complex and involves navigating through multiple contextual factors. Awareness of the dynamic nature of context should be considered when implementing innovations.

Assessment of scalability of evidence-based innovations in community-based primary health care: a cross-sectional study.

BACKGROUND: In 2013, the Canadian Institutes of Health Research funded 12 community-based primary health care research teams to develop evidence-based innovations. We aimed to explore the scalability of these innovations. METHODS: In this cross-sectional study, we invited the 12 teams to rate their evidence-based innovations for scalability. Based on a systematic review, we developed a self-administered questionnaire with 16 scalability assessment criteria grouped into 5 dimensions (theory, impact, coverage, setting and cost). Teams completed a questionnaire for each of their innovations. We analyzed the data using simple frequency counts and hierarchical cluster analysis. We calculated the mean number and standard deviation (SD) of innovations that met criteria within each dimension that included more than 1 criterion. The analysis unit was the innovation. RESULTS: The 11 responding teams evaluated 33 evidence-based innovations (median 3, range 1-8 per team). The innovations focused on access to care and chronic disease prevention and management, and varied from health interventions to methodological innovations. Most of the innovations were health interventions (n = 21), followed by analytical methods (n = 4), conceptual frameworks (n = 4), measures (n = 3) and strategies to build research capacity (n = 1). Most (29) met criteria in the theory dimension, followed by impact (mean 22.3 [SD 5.6] innovations per dimension), setting (mean 21.7 [SD 8.5]), cost (mean 17.5 [SD 2.1]) and coverage (mean 14.0 [SD 4.1]). On average, the innovations met 10 of the 16 criteria. Adoption was the least assessed criterion (n = 9). Most (20) of the innovations were highly ranked for scalability. INTERPRETATION: Scalability varied among innovations, which suggests that readiness for scale up was suboptimal for some innovations. Coverage remained largely unaddressed; further investigation of this critical dimension is necessary.

Resilience and resources among South Asian immigrant women as survivors of partner violence.

This study explored resilience among South Asian (SA) immigrant women who were survivors of intimate partner violence (IPV). Eleven women participated in in-depth interviews. Thematic analysis was conducted using constant comparison. We identified five cross-cutting themes: resources before and after the turning-point (i.e. decision to confront violence), transformations in self, modification of social networks, and being an immigrant. Women drew upon their individual cognitive abilities, social support, and professional assistance to move beyond victimization. All women modified their social networks purposefully. The changes in individual-self included an increased sense of autonomy, positive outlook, and keeping busy. The changes in collective-self occurred as women developed a stronger feeling of belonging to their adopted country. This hybrid identity created a loop of reciprocity and a desire to contribute to their community. Women were cognizant of their surmountable challenges as immigrants. SA immigrant women IPV survivors sought multiple resources at micro, meso and macro levels, signifying the need for socio-ecological approaches in programs and policies along with inter-sectoral coordination to foster resilience.

Asymptomatic perforation of large bowel and urinary bladder as a complication of ventriculoperitoneal shunt: report of two cases.

INTRODUCTION: Insertion of a ventriculoperitoneal (VP) shunt, the method of choice in the treatment of hydrocephalus, is often followed by various mechanical and/or infective complications. We present two children with asymptomatic perforation of the large bowel and urinary bladder, relatively rare and potentially severe complications of this surgical procedure. OUTLINE OF CASES: In both patients a VP shunt was implanted in the first month after birth; in a boy due to congenital hydrocephalus and in a girl due to the consequences of intracranial haemorrhage. Immediately after surgery, as well as during the further course, in both children growth and development were optimal and without any signs of infection or VP shunt malfunction. In the boy at age 6 months and in the girl at age 4 years, without any signs of complications, mothers noted the prominence of the VP shunt tip from the anus in the first case and from the urethral orifice in the second one. The VP shunts were immediately changed, so that both complications were resolved without any consequences. CONCLUSION: Insertion of a VP shunt represents the most frequent method of choice of the surgical treatment of hydrocephalus, but also potentially a highly risky procedure followed by various complications about which parents should be informed when patients are children. Owing to adequate approach in the follow-up of children with implanted VP shunt, large bowel and urinary bladder perforation, examples of severe and potentially fatal complications of this surgical intervention, could be disclosed on time and adequately resolved.

Religion versus ethnicity as predictors of unprotected vaginal intercourse among young adults.

BACKGROUND: Young adults in North America are at increasing risk for contracting HIV and sexually transmissible infections (STI). Racial differences in HIV or STI risk are well documented, but other cultural and demographic factors contributing to HIV or STI risk are poorly understood. Although religion may play an important role in sexual behaviour, little research has explored its association with sexual attitudes, beliefs and practices. The present study examined how ethnicity, religion, HIV knowledge and attitudes, and other demographic factors are associated with engaging in unprotected vaginal intercourse (UVI) in a diverse sample of unmarried young adults. METHODS: A cross-sectional study of 666 unmarried university students was conducted from 2005 to 2007, with participants completing an anonymous questionnaire on sexual attitudes and health for course credit. RESULTS: Approximately 50% of the respondents had engaged in any vaginal intercourse and 32.2% had engaged in UVI in the past 6 months. Multivariable analyses showed that increasing age, being in a relationship for more than 6 months, greater HIV knowledge, stronger attitudes supporting the use of condoms, and religion (but not ethnicity) were associated with engaging in UVI. Among the sexually active subset of the sample (n=332), religion was the only predictor of engaging in UVI. CONCLUSION: Ethnicity, which is often considered an important variable in sexual health research, does not appear to be associated with UVI when taking into account other demographic variables, particularly religion. Consideration of religion may be important in devising HIV prevention interventions, in order to implement them in accordance with particular religious beliefs.

[Alterations of c-Myc and c-erbB-2 genes in ovarian tumours].

INTRODUCTION: According to clinical and epidemiological studies, ovarian cancer ranks fifth in cancer deaths among women. The causes of ovarian cancer remain largely unknown but various factors may increase the risk of developing it, such as age, family history of cancer, childbearing status etc. This cancer results from a succession of genetic alterations involving oncogenes and tumour suppressor genes, which have a critical role in normal cell growth regulation. Mutations and/or overexpression of three oncogenes, c-erbB-2, c-Myc and K-ras, and of the tumour suppressor gene p53, have been frequently observed in a sporadic ovarian cancer. OBJECTIVE: The aim of the present study was to analyse c-Myc and c-erbB-2 oncogene alterations, specifically amplification, as one of main mechanisms of their activation in ovarian cancers and to establish a possible association with the pathogenic process. METHODS: DNA was isolated from 15 samples of malignant and 5 benign ovarian tumours, using proteinase K digestion, followed by phenol-chloroform isoamyl extraction and ethanol precipitation. C-Myc and c-erbB-2 amplification were detected by differential PCR. The level of gene copy increase was measured using the Scion image software. RESULTS: The amplification of both c-Myc and c-erbB-2 was detected in 26.7% of ovarian epithelial carcinoma specimens. Only one tumour specimen concomitantly showed increased gene copy number for both studied genes. Interestingly, besides amplification, gene deletion was also detected (26.7% for c-erbB-2). Most of the ovarian carcinomas with alterations in c-Myc and c-erbB-2 belonged to advanced FIGO stages. CONCLUSION: The amplification of c-Myc and c-erbB-2 oncogenes in ovarian epithelial carcinomas is most probably a late event in the pathogenesis conferring these tumours a more aggressive biological behaviour. Similarly, gene deletions point to genomic instability in epithelial carcinomas in higher clinical stages as the result of clonal evolution and selection.
