Purpose

This article presents a systematic review of the prevalence of violence against adolescents in the 22 countries of the Arab League.

Comparison between a laser fluorescence device and visual examination in the detection of occlusal caries in children

Occlusal surfaces of molars are especially susceptible to the development of caries due to the features, such as pits and deep fissures, of their anatomical structure.AimTo evaluate the efficiency of DIAGNOdent laser fluorescence measurements in comparison with visual examination for occlusal caries detection for first permanent molars in children.MethodsThe study involved 156 permanent molar teeth in 40 children aged 7–12 years. A relatively new technology, the fluorescence laser DIAGNOdent pen, was used for detecting and diagnosing caries on the occlusal surfaces of molars. The visual examination of fissures was based on the Ekstrand classification system.ResultsThe results showed a strong relationship between examination with the DIAGNOdent and visual inspection. DIAGNOdent’s sensitivity and specificity were 97% and 52%, respectively, indicating that the laser fluorescence DIAGNOdent pen is a reproducible and accurate diagnostic tool that may be very helpful in conjunction with visual examination in the detection of occlusal caries in permanent molars in children.     

Multifactorial pharmacogenetic analysis in colorectal cancer patients receiving 5-fluorouracil-based therapy together with cetuximab-irinotecan

AIM

To examine the predictive value of gene polymorphisms potentially linked to toxicity, clinical response, time to progression and overall survival, following cetuximab–tegafur-uracil (UFT)–irinotecan therapy.

METHODS

Fifty-two patients with advanced colorectal cancer were enrolled in an ancillary pharmacogenetic study of the phase II CETUFTIRI trial. Treatment consisted of 21 day cycles of cetuximab (day 1–day 8–day 15, 250 mg m⁻² week⁻¹ following a 400 mg m⁻² initial dose) together with irinotecan (day 1, 250 mg m⁻²) and UFT–folinic acid (days 1–14, 250 mg m⁻² day⁻¹ UFT, 90 mg day⁻¹ folinic acid). Analysed gene polymorphisms (blood DNA) were as follows: EGFR (CA repeats in intron 1, −216G>T, −191C>A), EGF (61A>G), FCGR2A (131Arg>His), FCGR3A (158Phe>Val), UDP-glycosyltransferase1-polypeptide A1 (TA repeats), TYMS (28 bp repeats, including the G>C mutation on the 3R allele, 6 bp deletion in 3′ UTR) and MTHFR (677C>T, 1298A>C).

RESULTS

Maximum toxicity grade was linked to EGFR−191C>A polymorphism, with 71.1% grade 3–4 toxicity in CC patients vs. 28.6% in other patients (P = 0.010). A tendency to a better response was observed in patients bearing the TYMS 3RG allele (P = 0.029) and those bearing the FCGR3A 158Val genotype (P = 0.020). The greater the score of favourable TYMS and FCGR3A genotypes, the better the response rate (P = 0.009) and the longer the overall survival (P = 0.007). In multivariate analysis, the score of favourable genotypes was a stronger survival predictor than the performance status.

CONCLUSIONS

Present data suggest the importance of FCGR3A 158Phe>Val and TYMS 5′ UTR polymorphisms in responsiveness and survival of patients receiving cetuximab–fluoropyrimidine-based therapy.     

The safety and quality of childbirth in the context of health systems: mapping maternal health provision in Lebanon

Objective

to provide basic information on the distribution (public/private and geographically) and the nature of maternity health provision in Lebanon, including relevant health outcome data at the hospital level in order to compare key features of provision with maternal/neonatal health outcomes.

Design

a self-completion questionnaire was sent to private hospitals by the Syndicate of Private Hospitals in collaboration with the study team and to all public hospitals in Lebanon with a functioning maternity ward by the study team in cooperation with the Ministry of Public Health.

Setting

childbirth in an institutional setting by a trained attendant is almost universal in Lebanon and the predominant model of care is obstetrician-led rather than midwife-led. Yet due to a 15-year-old civil war and a highly privatised health sector, Lebanon lacks systematic or publically available data on the organisation, distribution and quality of maternal health services. An accreditation system for private hospitals was recently initiated to regulate the quality of hospital care in Lebanon.

Participants

in total, 58 (out of 125 eligible) hospitals responded to the survey (46% total response rate). Only hospital-level aggregate data were collected.

Measurements

the survey addressed the volume of services, mode of payment for deliveries, number of health providers, number of labour and childbirth units, availability of neonatal intensive care units, fetal monitors and infusion rate regulation pumps for oxytocin, as well as health outcome data related to childbirth care and stillbirths for the year 2008.

Findings

the study provides the first data on maternal health provision from a survey of all eligible hospitals in Lebanon. More than three-quarters of deliveries occur in private hospitals, but the Ministry of Public Health is the single most important source of payment for childbirth. The reported hospital caesarean section rate is high at 40.8%. Essential equipment for safe maternal and newborn health care is widely available in Lebanon, but over half of the hospitals that responded lack a neonatal intensive care unit. The ratio of reported numbers of midwives to deliveries is three times that of obstetricians to deliveries.

Key conclusions and implications for practice

there is a need for greater interaction between maternal/neonatal health, health system specialists and policy makers on how the health system can support both the adoption of evidence-based interventions and, ultimately, better maternal and perinatal health outcomes.     

Modelling a preference-based index for EQ-5D using a non-parametric Bayesian method

Background

Conventionally, models used for health state valuation data have been parametric. Recently, a number of researchers have investigated the use of non-parametric Bayesian methods in this area.

Objectives

In this paper, we present a non-parametric Bayesian model to estimate a preference-based index for a five-dimensional health state classification, namely EQ-5D.

Methods

A sample of 2997 members of the UK general population valued 43 health states selected from a total of 243 health states defined by the EQ-5D using time trade-off technique. Findings from non-parametric modelling are reported in this paper and compared to previously used parametric estimations. The impact of respondent characteristics on health state valuations is also reported.

Results

The non-parametric models were found to be better at predicting scores in populations with different distributions of characteristics than observed in the survey sample. Additionally, non-parametric models were found to be better at allowing for the impact of respondent characteristics to vary by health state. The results show an important age effect with sex having some effect.

Conclusion

The non-parametric Bayesian models provide more realistic and better utility estimates from the EQ-5D than previously used parametric models have done. Furthermore, the model is more flexible in estimating the impact of covariates.

     

Predictors of complementary feeding practices among children aged 6–23 months in five countries in the Middle East and North Africa region

Ensuring diets of children aged 6–23 months meet recommended guidance is crucial for growth and development and for the prevention of malnutrition including stunting, wasting and micronutrient deficiencies. Despite some improvement, indicators related to undernutrition and overnutrition fall short of global targets in the Middle East and North Africa (MENA) region that consist of low‐ and middle‐income countries witnessing political and social changes and a nutrition transition. This research aims at reviewing the situation related to the diets of children aged 6–23 months in five selected countries in the MENA region, examining factors affecting complementary feeding and providing recommendations for guiding effective strategies to improve it. The study triangulated data on complementary feeding status and predictors from semistructured interviews with 30 key informants, and multivariable analysis of household surveys in Egypt, Jordan, Lebanon, State of Palestine and Sudan including data on refugees in Lebanon and Jordan. There remain considerable gaps in complementary feeding differing noticeably among geographic areas. Findings from qualitative and quantitative analyses showed that maternal factors, including maternal education and age, household level factors such as paternal education and wealth, community‐level factors (culture and geographic location), and utilization of health services, were associated with minimum dietary diversity (MDD), minimum meal frequency (MMF) and minimum acceptable diet (MAD) at varied levels in the five countries. Interventions to improve complementary feeding practices should include actions tailored to the needs of the population at multiple levels including at the caregiver''s level, household, service use, community and policy level.     

Long survival of patients with metastatic clear cell renal cell carcinoma. Results of real life study of 344 patients

The treatment landscape in metastatic renal cell carcinoma has changed fundamentally over the last decade by the development of antiangiogenic agents, mammalian target of rapamycin inhibitors and immunotherapy. Outside of the context of a clinical trial, the treatments are used sequentially. We describe results under real-life conditions of a sequential treatment strategy, before the era of immunotherapy. All patients were treated according to their prognostic score (either Memorial Sloan Kettering Cancer Center or International Metastatic Renal Cell Carcinoma Database Consortium) for advanced renal cell carcinoma. A treatment strategy involving 1 to 4 lines was determined including a rechallenge criterion for the repeat use of a treatment class. Three hundred forty-four patients were included over 3 years. Overall survival was 57 months in patients with good or intermediate prognosis and 19 months in patients with poor prognosis. In the former group, the proportions of patients treated with 2 to 4 treatment lines were 70%, 38% and 16%, respectively. The best objective response rates for lines 1 to 4 were 46%, 36%, 16% and 17%, respectively. Grade III/IV toxicity did not appear to be cumulative. The recommended strategy was followed in 68% of patients. A large proportion of patients with good or intermediate prognosis who progress after two lines of treatment still have a performance status good enough to receive a systemic treatment, which justifies such a strategy. Overall survival of patients with good and intermediate prognosis was long, suggesting a benefit from the applied approach. These results might be used as selection criterion for the treatment of patients in the era of immune checkpoint inhibitors.
