Ghanaian media coverage of violence against women and girls: implications for health promotion.

BACKGROUND: Violence against women and girls (VAWG) is an important public health issue. Framing studies indicate that how the news media cover public health issues is critical for designing effective health promotion interventions. Notwithstanding this, there is little research particularly in low-and middle-income country context examining how the news media frame VAWG. This paper examines news coverage of VAWG in Ghana, and the implications of this for health promotion. METHODS: This study used frame analysis as the methodological framework in examining how VAWG in Ghana is represented by the media. Qualitative content analysis approach to frame analysis was performed on 48 news articles which constituted the unit of analysis. RESULTS: The findings indicate that media framing of VAWG was episodic in nature as the acts of violence perpetrated against women and girls were presented as individual cases without reference to the wider social contexts within which they occurred. Similarly, victim blaming language was largely used in the news articles. In framing VAWG as an individual incident and women as helpless victims, the media fail to shape society's perception of VAWG as a social and public health issue. CONCLUSIONS: For the media in Ghana to contribute to the prevention of VAWG, there is the need for news coverage to focus on social construction of the issue, and also raise awareness about support services available to victims.

Improvement in Quality Metrics Outcomes and Patient and Family Satisfaction in a Neurosciences Intensive Care Unit after Creation of a Dedicated Neurocritical Care Team.

INTRODUCTION: Dedicated neurointensivists have been shown to improve outcome measurements in the neurosciences intensive care unit (NSICU). Quality outcome data in relation to patient and family satisfaction is lacking. This study evaluated the impact of newly appointed neurointensivists and creation of a neurocritical care team on quality outcome measures including patient satisfaction in a NSICU. METHODS: This is a retrospective study of data over 36 months from a 14-bed NSICU evaluating quality outcome measures and anonymous patient satisfaction questionnaires before and after neurointensivists appointment. RESULTS: After appointment of neurointensivists, patient acuity of the NSICU increased by 33.4% while LOS decreased by 3.5%. There was a decrease in neurosciences mortality (35.8%), catheter-associated urinary tract infection (50%), central line associated bloodstream infection (100%), and ventilator-associated pneumonia (50%). During the same time, patient satisfaction increased by 28.3% on physicians/nurses consistency (p = 0.025), by 69.5% in confidence/trust in physicians (p < 0.0001), by 78.3% on physicians treated me with courtesy/respect (p < 0.0001), and by 46.4% on physicians' attentiveness (p < 0.0001). Ultimately, patients recommending the hospital to others increased by 67.5% (p < 0.0001). CONCLUSION: Dedicated neurointensivists and the subsequent development of a neurocritical care team positively impacted quality outcome metrics, particularly significantly improving patient satisfaction.

Failure of the Platelet Function Assay (PFA)-100 to detect antiplatelet agents.

BACKGROUND: Antiplatelet therapy is a complicating factor in patients with traumatic brain injuries (TBI), as well as those with hemorrhagic cerebrovascular accidents (CVAs). Platelet Function Assay (PFA)-100 is a coagulation device that can detect platelet dysfunction caused by aspirin and adenosine diphosphate inhibition. Our retrospective study reviewed the effectiveness of PFA-100 in detecting platelet dysfunction caused by aspirin and clopidogrel and determined its clinical importance. METHODS: All patients with PFA-100 tests from January 2013 to February 2014 were collected. Diagnoses indicative of a TBI or CVA were chosen for analysis. Patients with a normal PFA-100 indicating no platelet dysfunction but with documented aspirin and/or clopidogrel use were selected. An extensive chart review was performed to determine the relevance to their clinical care. RESULTS: A total of 475 patients were evaluated with a PFA-100 from January 2013 to February 2014. PFA-100 detected platelet dysfunction as the result of pre-injury use of antiplatelet agents in TBI and CVA patients with a sensitivity of only 48.6% and a specificity of 74.8%. Had these antiplatelet medications been known during initial workup, these patients would have had a change in management that may have impacted their outcomes. CONCLUSION: Despite its common usage, the PFA-100 is an unreliable tool to assist in the management of TBI and CVA patients. Additional investigation into alternative methods for detecting platelet dysfunction is warranted.

Nucleosome dynamics: HMGB1 relaxes canonical nucleosome structure to facilitate estrogen receptor binding.

High mobility group protein 1 (HMGB1) interacts with DNA and chromatin to influence the regulation of transcription, DNA repair and recombination. We show that HMGB1 alters the structure and stability of the canonical nucleosome (N) in a nonenzymatic, ATP-independent manner. Although estrogen receptor (ER) does not bind to its consensus estrogen response element within a nucleosome, HMGB1 restructures the nucleosome to facilitate strong ER binding. The isolated HMGB1-restructured nucleosomes (N' and N″) remain stable and exhibit characteristics distinctly different from the canonical nucleosome. These findings complement previous studies that showed (i) HMGB1 stimulates in vivo transcriptional activation at estrogen response elements and (ii) knock down of HMGB1 expression by siRNA precipitously reduced transcriptional activation. The findings indicate that one aspect of the mechanism of HMGB1 action involves a restructuring of the nucleosome that appears to relax structural constraints within the nucleosome.

Incidence of cerebrospinal fluid leak following petrosectomy and analysis of avoidance techniques.

A cerebrospinal fluid (CSF) leak following skull base surgery can lead to meningitis, impaired wound healing, and often requires re-operation and/or CSF diversion. Thirty-two patients underwent a presigmoid, transpetrosal approach to skull base aneurysms and tumors. A vascularized temporalis muscle flap was utilized during the closure of the initial skull base reconstruction in 18 of the 32 patients. A temporary CSF diversion was utilized in 23 of the 32 patients. A permanent shunt was placed in eight patients. One patient developed a postoperative CSF leak from the contralateral ear due to a congenital abnormality in the middle ear. Another patient, who did not have a vascularized temporalis muscle flap reconstruction, developed a postoperative CSF leak in the context of an operation for recurrent tumor and prior radiation treatment. CSF diversion and vascularized temporalis muscle flaps are effective in preventing the development of postoperative CSF leaks following petrosectomy.

Frontiers in the surgical treatment of Parkinson's disease.

Despite the continued refinement of medical and surgical therapies, the treatment of Parkinson's disease (PD) remains challenging. Current treatment strategies are largely focused on managing the motor symptoms of the disease, either by dopamine-based medications or, in advanced stages, by the application of deep brain stimulation to more stably alter the function of the basal ganglia. Important advances have been made in the last decade, but unfortunately a number of the motor symptoms of late-stage PD remain poorly treated, and while currently available therapies address the symptoms of the disease, they fail to alter the course of the disease itself. This has spurred basic and clinical exploration on a number of fronts. Several centers have examined novel stimulation targets to treat refractory symptoms of gait difficulty and axial imbalance. Basic and clinical researchers are examining whether the use of deep brain stimulation might slow the progress of the disease and thus be a useful neuroprotective therapy if initiated earlier in the progression of the disease. An expanded understanding of the genetic and cellular events that underlie PD has led some researchers to explore the use of neurotrophic factors or genetic restoration to preserve threatened neuronal populations. Finally, there has been much research on the use of fetal mesencephalic or stem cell populations to restore dopaminergic function. In this report, we will examine each of these potential new surgical therapies and the promise they may hold for the future treatment of PD.
