Implementing and evaluating integrated care models for non-communicable diseases in fragile and humanitarian settings

In this commentary, we advocate for the wider implementation of integrated care models for NCDs within humanitarian preparedness, response, and resilience efforts. Since experience and evidence on integrated NCD care in humanitarian settings is limited, we discuss potential benefits, key lessons learned from other settings, and lessons from the integration of other conditions that may be useful for stakeholders considering an integrated model of NCD care. We also introduce our ongoing project in North Lebanon as a case example currently undergoing parallel tracks of program implementation and process evaluation that aims to strengthen the evidence base on implementing an integrated NCD care model in a crisis setting.

Neuroimaging findings in children with COVID-19 infection: a systematic review and meta-analysis

The COVID-19 pandemic has impacted individuals differently, and there's been a growing body of evidence pointing to neurological complications caused by the virus. However, our understanding of the range of neurological issues linked to SARS-CoV-2 infection in children is limited. This systematic review and meta-analysis aimed to assess the abnormal neuroimaging findings in pediatric COVID-19 patients, shedding light on this crucial aspect of the disease's impact on children. We conducted an extensive search in the PubMed, Medline, and ScienceDirect databases for observational studies reporting neuroimaging findings of the brain and spinal cord in children with COVID-19 between December 1, 2019, and October 30, 2021. Grey literature sources, including medRxiv and Google Scholar, were also explored. Pooled proportions of abnormal neuroimaging findings, categorized into neurovascular findings, ADEM-like lesions, encephalitic pattern, myelitis, transient splenial lesions, and other anomalies, were calculated using a random-effects model. Between-study heterogeneity was assessed using the χ2 statistic for pooled proportions and the inconsistency index I2. The Quality of the studies was evaluated using the NIH Quality Assessment Tool and the adapted Newcastle-Ottawa Scale. Our search yielded 9,605 articles, with 96 studies (involving 327 pediatric patients) included in the qualitative analysis. Of these, five reports (encompassing 111 patients) underwent quantitative analysis. The pooled proportion of pediatric COVID-19 patients with neurological symptoms and exhibiting abnormal neuroimaging findings was 43.74%. These findings were further categorized into neurovascular findings (8.22%), ADEM-like lesions (7.69%), encephalitic pattern (13.95%), myelitis (4.60%), transient splenial lesions (16.26%), and other abnormalities (12.03%). Insignificant between-study heterogeneity was observed in all categories, and our analysis did not reveal significant publication bias. In conclusion, a substantial proportion of pediatric COVID-19 patients with neurological symptoms have abnormal neuroimaging findings, underscoring the need for vigilant monitoring of neurological complications in this vulnerable population. Standardized reporting and long-term follow-up studies are essential to fully understand the implications of these findings. Collaborative research efforts will deepen our understanding of COVID-19's neurological dimensions in children and enhance clinical care for this population.

Arterial spin labeling (ASL-MRI) versus fluorodeoxyglucose-PET (FDG-PET) in diagnosing dementia: a systematic review and meta-analysis

BACKGROUND

Dementia is generally caused by neurodegenerative diseases affecting the brain, which leads to a progressive neurocognitive decline characterized by inability to perform major higher functioning tasks. Fluorodeoxyglucose-positron emission tomography (FDG-PET) scan is one of the main imaging tests performed for diagnostic purposes. However, with FDG-PET being quite expensive and not widely available, an attempt to find an alternative is set. Arterial-spin-labelling magnetic resonance imaging (ASL-MRI) is an increasingly investigated substitute to FDG-PET for the diagnosis of dementia. Thereby, the main purpose of this systematic review and meta-analysis is to compare the diagnostic ability of FDG-PET and ASL-MRI in detecting dementia.

METHODS

PRISMA checklist for diagnostic test accuracy was employed in outlining this paper. A literature search was done using several search engines including PubMed, Core, and Cochrane. Two researchers (HH and SH) extracted the essential information from all included articles. Risk of bias was evaluated by the Quality Assessment of Diagnostic Accuracy Studies tool, version 2 (QUADAS-2). A qualitative analysis and summary of studies' results were provided. In addition, a meta-analysis was executed based on the studies which involved sensitivity and specificity measures of diagnostic accuracy.

RESULTS

Fourteen total studies were included in the given review. Qualitative analysis of the articles showed that nine studies demonstrated an overlap between metabolic and perfused brain maps as derived by FDG-PET and ASL-MRI respectively, while the remaining five studies registered significant differences across both modalities, with superiority to FDG-PET. As for the meta-analysis implemented, summary ROC-curve analysis revealed that FDG-PET performed better than ASL-MRI, with pooled sensitivity being significantly higher for FDG-PET.

CONCLUSIONS

Comparing the diagnostic value of FDG-PET and ASL-MRI, the results of this systematic review and meta-analysis indicate that FDG-PET still has an advantage over ASL-MRI. Such implication could be related to the technical differences relating to both modalities, with ASL-MRI having lower temporal resolution. It's worth mentioning that specificity was rather quite similar among both modalities and some studies found an overridden metabolic and perfused images. These findings call for future research to focus their scope of investigation while exploring the diagnostic value of ASL-MRI.

Has the COVID-19 pandemic changed the utilization and provision of essential health care services from 2019 to 2020 in the primary health care network in Lebanon? Results from a nationwide representative cross-sectional survey

There is limited research soliciting the patient and staff perspectives on the overall effects of COVID-19 on the utilization and provision of primary care in Lebanon. The present study was part of a larger study on the overall effect of COVID-19 on both utilization and provision of essential health care services within the Lebanese primary health care network (PHCN). Here, we present the patient and staff perspectives on continuity of service provision, adherence to infection prevention and control measures, and the role of the PHCN in epidemic preparedness and response. We conducted a cross-sectional survey between June and July 2021 among patients who had received a health care service in 2019 or 2020 from registered primary healthcare centers (PHCs) in the network and among the respective PHC staff working during the same period. A total of 763 patients and 198 staff completed the surveys. Services were reported as interrupted by 15% of the total patients who used services either in 2020 only or in both 2019 and 2020. Access to chronic (67%) and acute medications (40%) were reported as the main interrupted services. Immunization also emerged as a foregone service in 2020. Among the staff, one third (33%) reported interruptions in the provision of services. Financial barriers rather than fear of COVID-19 were reported as main reasons for interruption. Both groups considered that the facilities implemented adequate infection prevention and control measures. They perceived that the PHCN maintained some essential healthcare services and that it should have played a bigger role in the response to the pandemic. There was a continuity in utilization and provision of services in the PHCN that was higher than expected, with non-communicable diseases and immunizations suffering more than other services.

Association between Periodontal Disease and Cognitive Impairment in Adults

INTRODUCTION

Periodontitis is a severe oral infection that can contribute to systemic inflammation. A large body of evidence suggests a role for systemic inflammation in the initiation of neurodegenerative disease. This systematic review synthesized data from observational studies to investigate the association between periodontitis and neuroinflammation in adults.

METHODS AND MATERIALS

A systematic literature search of PubMed, Web of Science, and Cumulative Index to Nursing and Allied Health Literature (CINAHL) was performed for studies published from the date of inception up to September 2021. Search terms for the exposure "oral disease" and outcome "dementia", "neuroinflammation" and "cognitive decline" were used. Study selection and data extraction were independently undertaken by two reviewers. The final eligible articles were included only if the exposure is periodontitis and the outcome is cognitive impairment or dementia or a topic related to this condition, and if the study was conducted in an adult population. The quality and risk of bias were assessed by Newcastle Ottawa Scale (NOS). Qualitative synthesis was used to narratively synthesize the results. Six cohort studies, three cross-sectional studies, and two case-control studies met the inclusion criteria. These eleven studies were only narratively synthesized. Meta-analysis was not performed due to the methodological heterogeneity of the studies.

RESULTS

The results of included studies show that chronic periodontitis patients with at least eight years of exposure are at higher risk of developing cognitive decline and dementia. Oral health measures such as gingival inflammation, attachment loss, probing depth, bleeding on probing, and alveolar bone loss are associated with cognitive impairment. The reduction of epidermal growth factor (EGF), interleukin 8 (IL-8), interferon γ-induced protein 10 (IP-10), and monocyte chemoattractant protein-1 (MCP-1) in addition to over expression of interleukin 1-β (IL-1β) are significant in patients suffering from cognitive decline with pre-existing severe periodontitis.

CONCLUSIONS

All the included studies show evidence of an association between periodontitis and cognitive impairment or dementia and Alzheimer's disease pathology. Nonetheless, the mechanisms responsible for the association between periodontitis and dementia are still unclear and warrant further investigation.

Utility values and its time to deterioration in breast cancer patients after diagnosis and during treatments

BACKGROUND

The potential effects of breast cancer (BC) on health-related quality of life (HRQoL) should be considered in clinical and policy decision-making, as the economic burden of BC management is currently assessed. In the last decades, time-to-HRQoL score deterioration (TTD) has been proposed as an approach to the analysis of longitudinal HRQoL in oncology. The main objectives of the current study were to investigate the evolution of the utility values in BC patients after diagnosis and during follow-ups and to evaluate the TTD in utility values among women in all stages of BC.

METHODS

Health-state utility values (HSUV) were assessed using the EuroQol 5-Dimension 3-Level at diagnosis, at the end of the first hospitalization and 3 and 6 months after the first hospitalization. For a given baseline score, HSUV was considered to have deteriorated if this score decreased by ≥ 0.08 points of the EQ-5D utility index score and ≥ 7 points of the EQ visual analogue scale. TTD curves were calculated using the Kaplan-Meier estimation method.

RESULTS

Overall 381 patients were enrolled between February 2006 and February 2008. The highest proportions of respondents at the baseline and all follow-ups reporting some and extreme problems were in pain discomfort and anxiety/depression dimensions; more than 80% of patients experienced a deterioration in EQ-5D utility index score and EQ VAS score with a median TTD of 3.15 months and 6.24 Months, respectively.

CONCLUSIONS

BC patients undergoing therapy need psychological support to cope with their discomfort, pain, depression, anxiety, and fear during the process of diagnosis and treatment to improve their QoL.

Cross-Cultural Adaptation and Validation of the Arabic Version of the Rating Anxiety in Dementia Scale

Objectives: This study aims to cross-culturally adapt the Rating Anxiety in Dementia (RAID) scale into Arabic language, evaluate its psychometric properties in a sample of Lebanese patients with dementia and determine the optimal cutoff for the identification of anxiety.Methods: A cross-sectional study was carried out with a sample of 136 patients with dementia aged 55 years and above. RAID-A was administered to a formal caregiver of the patient as well as a battery of psychological tools namely Hamilton anxiety scale (HAM-A) and Neuropsychiatric Inventory anxiety subscale (NPI-A). The Structured Clinical Interview for the Diagnostic and Statistical Manual of Mental Disorders, 5th Edition (DSM-5) was used to establish a clinical diagnosis of generalized anxiety disorder (GAD).Results: RAID-A scale demonstrated high internal consistency (Cronbach's a = 0.82) and test-retest reliability (Intraclass coefficient = 0.99). Significant correlations were found between RAID-A total score and both NPI-A (r = 0.43) and HAM-A (r = 0.88) suggesting good concurrent validity. Results from the receiver operating curve analysis identified a score of 11 as the optimal cutoff for the diagnosis of GAD with a sensitivity of 91% and a specificity of 82%.Conclusions: The Arabic version of the RAID scale exhibits good psychometric properties.Clinical Implications: RAID is a valid tool to measure anxiety in Arabic elder patients suffering from dementia.

Factors Associated with Health-Related Quality of Life in Women with Breast Cancer in the Middle East: A Systematic Review

Objectives: The aim of the present systematic review was to identify the factors that potentially influence health-related quality of life (HRQoL) in women with breast cancer (BC) in the Middle East. Methods: A systematic search of the PubMed, Ovid Medline, Cochrane, Embase, Cumulative Index to Nursing and Allied Health Literature (CINAHL), Scopus, and Ebscohost databases was conducted to identify all relevant articles published in peer-reviewed journals up to April 2018. The keywords were “Health related quality of life”, “Breast Cancer”, and “Middle East countries”. The Newcastle–Ottawa (NOS) scale was used to evaluate the methodological quality of the included studies. Due to the methodological heterogeneity of the identified studies, no statistical pooling of the individual effect estimates was carried out; instead, the results were summarized descriptively. Results: A total of 5668 articles were screened and 33 studies were retained. The vast majority of these studies were cross-sectional and only two were longitudinal prospective studies. Concerning the methodological quality, only 39% were of high quality. Our comprehensive literature review identified several modifiable and non-modifiable risk factors associated with HRQoL, including sociodemographic, clinical, and treatment-related factors as well as behavioral and psychosocial factors. Conclusion: This study has many implications for clinical practice and may provide a framework for establishing policy interventions to improve HRQoL among women with BC. Healthcare systems in the Middle East are encouraged to develop interventional programs targeting modifiable factors, particularly socio-demographic, behavioral, and psychosocial factors.

Trail Making Test: normative data for the Lebanese adult population

OBJECTIVE

Trail Making Test (TMT) is a widespread neuropsychological test used to detect cognitive impairment in diverse neuropsychological conditions. Several studies have shown that TMT performance is influenced by different demographic factors. Thus, the present study aims to explore the effect of gender, age, and education on TMT basic and derived scores and to provide normative data for the Lebanese adult population.

METHOD

A total of 225 healthy Lebanese adults (aged between 18 and 64) were recruited. The two parts of the TMT were administered to the participants. Regression based strategy was applied to generate normative data.

RESULTS

The results showed statistically significant effect of age and level of education on the TMT-A, TMT-B as well as the difference score TMT B -A. However, the ratio score was affected only by the age. Gender did not have any effect on TMT performance. An interactive calculator was created to calculate estimated Z-scores based on corresponding predictions of linear regression model. The calculator provides also percentile ranks.

CONCLUSIONS

The present study provides the first normative data for the TMT among the Lebanese population. Neuropsychologists in Lebanon will benefit from this outcome in order to improve the accurate detection of visual scanning/processing speed and executive function deficits in clinical settings for the adult population.

Assessment of neuropsychiatric symptoms in dementia: validity and reliability of the Lebanese version of the neuropsychiatric inventory questionnaire

This study aims to examine the psychometric properties of an Arabic version of the Neuropsychiatric Inventory Questionnaire (NPI-Q) that evaluates neuropsychiatric symptoms in patients with dementia. A cross-sectional study was carried out with a sample of 136 Lebanese demented patients aged 63-98 years. NPI-Q was completed by the patients' primary caregiver and standard NPI was administered through personal interview by an experienced research assistant to the same caregiver. The internal consistencies of the Arabic NPI-Q total and distress scale were 0.680 and 0.684 respectively. One week test-retest reliability of the total NPI-Q and distress scores were 0.991 and 0.988 respectively (p-value <0.0001 for both). The NPI-Q correlated significantly with the standard NPI in individual and total symptom scores as well as caregiver distress scores. Exploratory factor analysis extracted five factors that explained 64.7% of variances. The prevalence of analogous symptoms reported on the NPI and NPI-Q differed on average by 3% while moderate or severe symptom ratings differed on average by 1%. The Arabic version of the NPI-Q showed evidence of good psychometric properties indicating that it is a suitable tool for the routine assessment of neuropsychiatric symptoms for Lebanese patients with dementia in clinical settings.

Modified Wisconsin Card Sorting Test (M-WCST): Normative Data for the Lebanese Adult Population

The aim of this study was to generate normative data on the M-WCST in a Lebanese adult population and to examine the relationship between performance on this task and demographic variables. The sample consisted of 220 healthy adults aged between 18 and 64 years. Regression-based strategy was applied to generate normative data. The results showed a statistically significant effect of age and level of education on the M-WCST measures, whereas gender was not significant. Demographically calibrated percentiles and scaled scores were created. Finally, this study was the first to provide normative-adjusted tables for the M-WCST scores in Lebanon.

Outdoor particulate matter (PM) and associated cardiovascular diseases in the Middle East

Air pollution is a widespread environmental concern. Considerable epidemiological evidence indicates air pollution, particularly particulate matter (PM), as a major risk factor for cardiovascular diseases (CVD) in the developed countries. The main objective of our review is to assess the levels and sources of PM across the Middle East area and to search evidence for the relationship between PM exposure and CVD. An extensive review of the published literature pertaining to the subject (2000-2013) was conducted using PubMed, Medline and Google Scholar databases. We reveal that low utilization of public transport, ageing vehicle fleet and the increasing number of personal cars in the developing countries all contribute to the traffic congestion and aggravate the pollution problem. The annual average values of PM pollutants in the Middle East region are much higher than the World Health Organization 2006 guidelines (PM2.5 = 10 μg/m(3), PM10 = 20 μg/m(3)). We uncover evidence on the association between PM and CVD in 4 Middle East countries: Iran, Kingdom of Saudi Arabia, Qatar and the United Arab Emirates. The findings are in light of the international figures. Ambient PM pollution is considered a potential risk factor for platelet activation and atherosclerosis and has been found to be linked with an increased risk for mortality and hospital admissions due to CVD. This review highlights the importance of developing a strategy to improve air quality and reduce outdoor air pollution in the developing countries, particularly in the Middle East. Future studies should weigh the potential impact of PM on the overall burden of cardiac diseases.
