Hemiballismus from a parietal stroke in a Parkinson patient.

Stroke-induced hemiballismus (HB) has been reported to improve motor function in people with Parkinson's disease (PD). We report on a patient who developed HB from a parietal infarct. The HB was improved by very low-dose clozapine but the HB did not improve the parkinsonism. This suggests that HB itself, whether from a lesion in the subthalamic nucleus or elsewhere, is not what improves motor function in PD; instead, the physiological function of the damaged structure is the determining factor.     

Dental caries experience and related factors among a clustered random sample of students in occupied Palestinian territory: a cross-sectional study

Background

Dental caries is still the most prevalent chronic disease worldwide. In the occupied Palestinian territory, data about oral health status and its determinants are scarce. This study aimed to assess the prevalence of dental caries and associated factors among schoolchildren in a random sample of marginalised schools in the West Bank.

Safety and Efficacy of Intracoronary Thrombolysis as Adjunctive Therapy to Primary PCI in STEMI: A Systematic Review and Meta-analysis

BackgroundPrimary percutaneous coronary intervention (PPCI) is the preferred method of reperfusion in ST-elevation myocardial infarction. However, microvascular perfusion is often impaired due to distal embolization of thrombus. Intracoronary (IC) thrombolysis may attenuate thrombotic burden. We conducted a meta-analysis comparing the benefits and risks of IC thrombolytic therapy as an adjunct to PPCI.MethodsRandomized controlled trials (RCTs) were identified through search of Medline, EMBASE, Scopus, Web of Science, Cochrane Library (Cochrane Reviews and Cochrane Protocols), PROSPERO, and clinicaltrials.gov from 1946 to January 2019. Studies included patients with ST-elevation myocardial infarction undergoing primary PCI receiving IC thrombolytic agents. Both safety and efficacy outcomes were explored. Data were combined using a fixed-effects model.ResultsOf 1278 citations identified, 6 RCTs (890 patients; 519 IC thrombolytic and 371 IC placebo) were included. Post-PCI thrombolysis in myocardial infarction (TIMI) flow grade 2/3 occurred in 97.1% of the IC thrombolytic group vs 95.1% of the IC placebo group (odds ratio [OR], 0.57; 95% confidence interval [CI], 0.28-1.17; P = 0.13). Complete ST-segment resolution was more common with IC thrombolysis (OR, 0.29; 95% CI, 0.15-0.57; P = 0.0003). There was a strong trend favouring fewer in-hospital major adverse cardiac events with IC thrombolysis when compared with IC placebo (OR, 0.64; 95% CI, 0.41-1.01; P = 0.05). There was no difference in bleeding (TIMI major, TIMI minor, and Bleeding Academic Research Consortium [BARC] 3-5 bleeds) between the 2 groups (OR, 1.36; 95% CI, 0.38-3.54; P = 4.84).ConclusionsGiven the limited studies to date, our meta-analysis suggests that a targeted IC thrombolytic approach is safe and potentially effective to augment PPCI. However, these findings deserve confirmation in a larger RCT.     

Human resources for health in Palestine: a policy analysis. Part II. The process of policy formulation and implementation

This article is the presentation of part II of the analysis aiming at providing an insight and better understanding of human resources for health development within a conflicting and transitional context. This part focuses on the human resources for health (HRH) policy development in Palestine taking into consideration the critical elements in policy formulation and implementation, such as sound data based policy and planning, key stakeholders, role and implications of international cooperation. Moreover, it examines recent progress of HRH policy and constraints for implementation. Part I addresses the current situation and recent developments in HRH in Palestine.     

Organizing health care within political turmoil: the Palestinian case

Palestinians were given control over their own health services in late 1994. Since then they have been facing the challenge of reorganizing disordered health services into a cohesive, regulated and sustainable health care system. This paper focuses on the experience of organizing health care during political instability. It considers the ways that health care is currently provided and funded in the Palestinian Territories. The patterns of accessibility to health care services in terms of insurance coverage and provision (physical allocation) of services are discussed. Finally, the major health care policy changes in this transitional period are examined.     

Optical Coherence Tomography Imaging for Diabetic Retinopathy and Macular Edema

Optical coherence tomography (OCT) is a noninvasive imaging modality that uses low-coherent interferometry to visualize an optical cross-section of biological tissues. Over the past two decades, the ability to perform OCT imaging of the neural retina has afforded clinicians and researchers a highly reproducible method of diagnosing and following diabetic macular edema (DME) that compares favorably to other methods of DME assessment such as clinical examination and fundus photography. Although central subfield mean thickness has been the OCT parameter most commonly used to evaluate DME in clinical research trials, OCT also allows evaluation of morphologic changes that occur in DME, including compact retinal thickening, intraretinal cystic changes, subretinal fluid, and vitreomacular traction. OCT parameters have been shown to be only moderately correlated with visual acuity. However, improvements in technology leading to higher resolution, faster acquisition speed, image registration, and three-dimensional imaging that are available with newer spectral domain OCT models may allow future identification of valid OCT-derived surrogate markers for visual function in patients with diabetes.     

Measuring safety culture in Palestinian neonatal intensive care units using the Safety Attitudes Questionnaire

Purpose

This study aimed to measure safety culture, examine variations among neonatal intensive care units (NICUs), and assess the associations with caregiver characteristics.

Materials and Methods

A cross-sectional design was used, utilizing the Arabic version of the Safety Attitudes Questionnaire, administered to all 305 nurses and physicians working in the 16 NICUs in the West Bank.

Results

There were 204 participants, comprising of mainly nurses (80.4%), women (63%), 30 years or younger (62.6%), holding a bachelor's degree or more (66.7%), and with at least 5 years of experience in the profession (60.3%). Safety Attitudes Questionnaire mean domain scores ranged from 71.22 for job satisfaction to 63 for stress recognition on a 100-point scale; the scores varied significantly among NICUs (P < .05). About 85% of the participants rated the safety grade either excellent or very good; 71.0% did not report any event in the past year.

Conclusions

We found large variations in safety culture within and between a comprehensive sample of Palestinian NICUs. The findings suggest the need for a customized approach that builds on existing strengths and targets areas of opportunities for improvement to optimize health care delivery to the most vulnerable of patients, sick newborns in the NICU setting.

Apoptosis Induction by SAHA in Cutaneous T-Cell Lymphoma Cells Is Related to Downregulation of c-FLIP and Enhanced TRAIL Signaling

Suberoylanilide hydroxamic acid (SAHA) has been approved for the treatment of cutaneous T-cell lymphoma (CTCL), but its mode of action remained largely elusive. As shown here in four CTCL cell lines, loss of cell viability correlated with significant time- and dose-dependent induction of apoptosis, whereas cytotoxicity was less pronounced. Both extrinsic and intrinsic apoptosis pathways were activated, as seen by processing of initiator caspases 8 and 9, loss of mitochondrial membrane potential, and cytochrome c release. Characteristically, antiapoptotic mediators such as Mcl-1, XIAP, survivin, and c-FLIP were downregulated. Consistent with its critical function, c-FLIP overexpression resulted in a significant decrease of SAHA-mediated apoptosis. Enhanced sensitivity to TRAIL (TNF-related apoptosis-inducing ligand) and enhanced TRAIL signaling was seen in CTCL cell lines with high sensitivity, whereas cell lines with moderate response were characterized by downregulation of TRAIL-R2 and weaker TRAIL expression. Comparable proapoptotic responses to SAHA and to the combination with TRAIL were seen in ex vivo tumor T cells of CTCL patients. Thus, activation of extrinsic apoptosis pathways, related to c-FLIP downregulation and enhanced TRAIL signaling, appeared as characteristic for CTCL cell responsiveness to SAHA. An improved understanding of the pathways may facilitate its targeted use and the selection of suitable combinations.     

Increase in invasive pneumococcal disease in children associated with shortage of heptavalent pneumococcal conjugate vaccine

The authors investigated the impact of heptavalent pneumococcal conjugate vaccine (PCV7) shortage on the rate of invasive pneumococcal disease (IPD). Vaccination status and number of doses delivered was determined. Regression analysis using an exponential decay model was used to predict the expected rate of IPD in the shortage period if IPD continued to decline at the same rate as in the availability period. The rate of IPD decreased from 15.5 to 6.5 with vaccine availability (P < .00001) and increased to 7.2 with shortage (P = .69). Based on the model, IPD rate would have been 3.6 if the decrease continued at the same rate when there was no shortage; this was statistically significant (95% prediction interval, 2.7-4.1). The rate of IPD correlated directly with the number of PCV7 doses delivered, r = -.98. Continuous availability of the PCV7 would have resulted in a statistically significant lower IPD rate compared to the measured IPD rate in the vaccine shortage period.
