Exposure to war trauma and PTSD among parents and children in the Gaza strip

Objective Exposure to war trauma has been independently associated with posttraumatic stress (PTSD) and other emotional disorders in children and adults. The aim of this study was to establish the relationship between ongoing war traumatic experiences, PTSD and anxiety symptoms in children, accounting for their parents’ equivalent mental health responses. Methods The study was conducted in the Gaza Strip, in areas under ongoing shelling and other acts of military violence. The sample included 100 families, with 200 parents and 197 children aged 9–18 years. Parents and children completed measures of experience of traumatic events (Gaza Traumatic Checklist), PTSD (Children’s Revised Impact of Events Scale, PTSD Checklist for parents), and anxiety (Revised Children’s Manifest Anxiety Scale, and Taylor Manifest Anxiety Scale for parents). Results Both children and parents reported a high number of experienced traumatic events, and high rates of PTSD and anxiety scores above previously established cut-offs. Among children, trauma exposure was significantly associated with total and subscales PTSD scores, and with anxiety scores. In contrast, trauma exposure was significantly associated with PTSD intrusion symptoms in parents. Both war trauma and parents’ emotional responses were significantly associated with children’s PTSD and anxiety symptoms. Conclusions Exposure to war trauma impacts on both parents’ and children’s mental health, whose emotional responses are inter-related. Both universal and targeted interventions should preferably involve families. These could be provided by non-governmental organizations in the first instance.     

Musculoskeletal Training for Orthopaedists and Nonorthopaedists: Experiences in India

In India, health policies, services, health indices, and medical education are improving despite the country’s enormous population and limited resources. Orthopaedic training in India should be geared to serve the predominantly rural population (72% of total population) living in some 550,000 villages, but unless the basic amenities improve in villages and towns, orthopaedists will remain averse to serving in these areas. Traditional practitioners play an important role in musculoskeletal trauma care in villages and even some town and city areas, and hence cannot be ignored. We suggest a stratified system of orthopaedic training for medical graduates, postgraduates, and paramedics with a well-defined need-based curriculum, and a clear cut division of labor, terms, and conditions to suit the stratified social and demographic structure of India. This stratified system is intended to provide appropriate musculoskeletal trauma care services to the rural population, reduce neglected and mismanaged trauma, consequently avoiding subsequent orthopaedic disability, and reduce the financial burden of managing these cases. This system also intends to prevent overloading of teaching hospitals and apex institutes and ensure availability of subspecialized orthopaedic services in the country at designated centers. Traditional practitioners shall be periodically educated regarding safe orthopaedic practices, which are anticipated to yield improved trauma care services.

Response to treatment and survival of patients with non-small cell lung cancer undergoing somatic EGFR mutation testing

Somatic mutations in the epidermal growth factor receptor (EGFR) gene are associated with clinical response and prolonged survival in patients with non-small cell lung cancer (NSCLC) treated with EGFR tyrosine kinase inhibitors (TKIs). We began screening patients for somatic EGFR mutations by DNA sequencing as part of clinical care in 2004. We performed a retrospective cohort study of 278 patients with NSCLC referred for EGFR testing over a 10-month period. Tumor samples underwent direct DNA sequence analyses of EGFR exons 18 through 24. We determined the clinical characteristics and EGFR mutation status of the patients and analyzed their response to therapy and survival. EGFR somatic mutations were identified in 68 (24%) of patients. A minimal smoking history was the strongest clinical predictor of harboring a mutation. In multivariable analyses, each pack-year of smoking corresponded to a 5% decreased likelihood of having an EGFR mutation. Among 92 patients with unresectable disease undergoing subsequent systemic therapy, EGFR mutations were associated with an increased response rate to EGFR TKIs (p < .0001) but not chemotherapy. Overall survival was significantly prolonged in EGFR mutation-positive patients (p = .001), with a median survival of 3.1 years compared with 1.6 years in mutation-negative patients, after adjusting for age, gender, and stage at diagnosis. Integrating molecular profiling into clinical care is feasible in NSCLC patients and provides useful clinical information.     

Disruption of prepulse inhibition of the startle reflex by the preferential D<Subscript>3</Subscript> agonist ropinirole in healthy males

Rationale Emerging evidence from agonist–antagonist studies suggests a role for the dopamine D₃ receptor subtype in the regulation of PPI in animals, but such evidence is lacking for human subjects. Objectives This study examines the effect of the preferential D₃ agonist ropinirole on PPI in humans. Methods PPI was tested in 12 healthy men in three sessions associated with ropinirole 0.25 mg, ropinirole 0.5 mg, or placebo according to a balanced, crossover, double-blind design. Two prepulses (75- and 85-dB white noise bursts) and two lead intervals (50 and 80 ms) were employed. Results Ropinirole 0.5 mg significantly reduced prepulse inhibition (PPI) with both prepulses at the 80-ms lead intervals. There was no effect of treatment on startle amplitude and habituation. Conclusions These results suggest a role for the dopamine D₃ receptor in the mediation of human PPI, although a contribution from ropinirole’s agonistic activity at the D₂ receptor cannot be entirely excluded. Firm conclusions on the role of the D₃ receptor in the modulation of human PPI can only be drawn with the use of genetic approaches or more selective ligands for this receptor.

Norton, Waterlow and Braden scores: a review of the literature and a comparison between the scores and clinical judgement

Aims and objectives. To consider the validity and reliability of risk assessment scales for pressure ulcers. Background. Pressure ulcers are a major problem worldwide. They cause morbidity and lead to mortality. Risk assessment scales have been available for nearly 50 years, but there is insufficient evidence to state with any certainty that they are useful. Design. A literature review and commentary. Methods. Bibliographic databases were searched for relevant papers, a critical review was completed on relevant papers. Results. There is contradictory evidence concerning the validity of risk assesment scales. The interaction of education, clinical judgement and use of risk assessment sakes has not been fully explored. It is not known which of these is most important, nor whether combining them results in better patient care. Conclusions. There is a need for further work. A study exploring the complex interaction of risk assessment scales, clinical judgement and education and training is introduced. Relevance to clinical practice. Nurses may be wasting their time conducting risk assessment scoring if clinical judgement and/or education are sufficient to assess pressure ulcers risk.     

Recurrent responses to non-small cell lung cancer brain metastases with erlotinib

We report the case of a Caucasian female never smoker with erlotinib sensitive metastatic non-small cell lung cancer in the brain. Having progressed after receiving whole brain radiotherapy, her brain metastases responded both initially and on re-treatment with erlotinib. However, her extra-cranial disease remained erlotinib-resistant throughout. This case demonstrates that brain metastases may be sensitive to erlotinib and also highlights the oligoclonal nature of non-small cell lung cancer reflected by differential tyrosine kinase inhibitor tumour sensitivity. On the basis of this case we suggest that erlotinib should be considered in the treatment paradigm for patients with intra-cranial disease and propose further study into the continued use of this drug in the situation where there is a differential response.     

Is the Brazilian pharmaceutical policy ensuring population access to essential medicines?

Non-communicable diseases account for more than 50% of deaths in adults aged 15–59 years in most low income countries. Depression and diabetes carry an enormous public health burden, making the identification of risk factors for these disorders an important strategy. While socio-economic inequalities in chronic diseases and their risk factors have been studied extensively in high-income countries, very few studies have investigated social inequalities in chronic disease risk factors in low or middle-income countries. Documenting chronic disease risk factors is important for understanding disease burdens in poorer countries and for targeting specific populations for the most effective interventions. The aim of this review is to systematically map the evidence for the association of socio-economic status with diabetes and depression comorbidity in low and middle income countries. The objective is to identify whether there is any evidence on the direction of the relationship: do co-morbidities have an impact on socio-economic status or vice versa and whether the prevalence of diabetes combined with depression is associated with socio-economic status factors within the general population. To date no other study has reviewed the evidence for the extent and nature of this relationship. By systematically mapping the evidence in the broader sense we can identify the policy and interventions implications of existing research, highlight the gaps in knowledge and suggest future research. Only 14 studies were found to analyse the associations between depression and diabetes comorbidity and socio-economic status. Studies show some evidence that the occurrence of depression among people with diabetes is associated with lower socio-economic status. The small evidence base that considers diabetes and depression in low and middle income countries is out of step with the scale of the burden of disease.
