RESUMO

The impact of conflict and crisis on maternal and child health underscores the need for reliable research in vulnerable populations. Lebanon, amidst ongoing economic collapse, political instability, and healthcare system strain, offers a case study for exploring these impacts, particularly on preterm babies and their development. This study aims to assess the feasibility of establishing a prospective cohort of mothers and their full-term and preterm babies in Lebanon, examining the association between social determinants, preterm birth, and developmental outcomes amidst the nation's multifaceted crises. The planned cohort involves 50 full-term and 50 preterm mother-baby pairs recruited at birth and followed up to 9-12 months post-birth. Data collection spans social determinants, perceived stress, social support, quality of life, and developmental assessments. Challenges in recruitment, follow-up, and data collection in the context of Lebanon's socio-political and economic turmoil are evaluated, alongside ethical considerations for research in vulnerable populations. Preliminary findings highlight substantial recruitment and follow-up challenges, notably due to population mobility, economic instability, and healthcare access issues. Despite these obstacles, 113 mother-baby pairs have been recruited. Early analysis reveals significant stress and reduced quality of life among mothers, particularly those with preterm infants, against a backdrop of declining birth rates and healthcare worker exodus. Conducting research in crisis settings like Lebanon presents unique methodological and ethical challenges but remains crucial for understanding and improving health outcomes in vulnerable populations. The study underscores the importance of adaptable research designs and ethical diligence in crisis research, highlighting the need for interventions tailored to these contexts. Establishing a mother and child cohort in Lebanon's crisis-ridden setting is faced with many challenges but is essential for guiding future interventions. Research in such contexts is needed to address health disparities and supporting vulnerable populations, emphasizing the need for dedicated funding and innovative research approaches in times of crisis.

RESUMO

BACKGROUND: High resilience increases nurses' ability to cope with job-related stressors and enhances job satisfaction and, consequently, their retention. The study aims to identify resilience predictors and perceptions of transformational leadership in a convenience sample of registered nurses in Lebanon. METHODS: An anonymous cross-sectional survey of a convenience sample of 240 registered nurses working for more than a year at three private hospitals in an underserved area in South Lebanon was used. The survey instrument included demographic questions, the True Resilience Scale ©, and the Global Transformational Leadership Scale. Multiple linear regression was used to assess the predictors of resilience after a descriptive analysis of the study variables. RESULTS: The survey response rate was 85%. The nurses' mean resilience score was 119.4 (SD 15.3), and their perception of transformational leadership score was M = 25.0, SD = 6.8. Compared to bedside nurses, nurse managers, nurses with more than five years of experience, and nurses in critical nursing units had statistically significant higher resilience scores (p < 0.05). Resilience scores and perception of global transformational leadership were moderately correlated (r = 0.53, p < 0.05). In the final multiple linear regression model, 30% of the variation in resilience scores was explained by designation (p < 0.05) and perception of Global Transformational Leadership (p < 0.01). Perception of global transformational leadership scores explained 29% of the variance in resilience scores. Designation and perception of global transformational leadership predicted resilience in this sample. CONCLUSIONS: A national survey of the Lebanese nursing workforce is needed to achieve an improved predictive model and support policy developments to increase resilience among bedside nurses and retain them in the nursing workforce. Nurse administrators can help by strengthening their transformational leadership behaviors. Consistent use of transformational leadership styles will strengthen bedside nurses' resilience, increase nurse retention, and help sustain the Lebanese nursing workforce.

RESUMO

BACKGROUND: Tobacco use is one of the major public health threats globally. Community pharmacists are uniquely positioned to offer tobacco cessation services owing to their easy accessibility by the public. To prepare Qatar community pharmacists to develop the competencies and skills required to offer smoking cessation services, an intensive tobacco control education program was designed and implemented. The study aimed to assess the impact of the tobacco education program on the pharmacists' skills and competence. METHODS: A random sample of community pharmacists in Qatar was chosen for participation in the program. Consenting participants were randomly assigned to either intervention or control groups. The intervention group received an intensive education program on treatment of tobacco-use disorder, while a short didactic session on a non-tobacco-related topic was delivered to the control group. The pharmacists' tobacco cessation skills and competencies were assessed using an Objective Structured Clinical Examination (OSCE). RESULTS: A total of 54 and 32 community pharmacists in the intervention group and the control group, respectively, completed the OSCE. The intensive tobacco education group achieved significantly higher total scores than the control group in all the OSCE cases. Specifically, the mean total scores for the intervention group were 15.2, 15.3, 14.2, 14.6, 16.3, and 15.2 compared to 8.8, 6.2, 7.7, 9.2, 8.3, and 11.3 for the control group (p < 0.001) for cases one to six respectively. CONCLUSION: The study demonstrated that an intensive tobacco cessation education program can improve pharmacists' tobacco cessation skills and increase their tobacco cessation counseling abilities. TRIAL REGISTRATION: Clinical Trials NCT03518476 ( https://clinicaltrials.gov/ct2/show/NCT03518476 ) Registration date: May 8, 2018.

RESUMO

INTRODUCTION: Stroke in air travelers is being increasingly recognized. We report on stroke among passengers arriving at or transiting through a busy air travel hub. METHODS: The stroke database of the sole tertiary care center for stroke in a large busy international hub was interrogated. Demographic data of transit passengers, their stroke risk factors, stroke severity, National Institutes of Health Stroke Scale (NIHSS), acute stroke interventions, discharge status and outcome utilizing the Modified Raking scale (mRS) were retrieved and compared between passengers and non-passenger controls. RESULTS: Forty-three flight-related stroke patients were compared to 2564 non-passenger stroke patients. The mean age in the flight-related stroke group was 59.53±10.83 years, 30/43 (69.8%) were males. The stroke subtypes were ischemic in 30 (69.8%) patients, hemorrhagic in 9 (20.9%), and transient ischemic attack in 3 (7.0%), with one cerebral sinus venous thrombosis (2.3%). The mean NIHSS score was 7.79±6.44 in passengers, demonstrating moderate severity. Ten patients (23.3%) received thrombolysis, one (2.3%) received thrombectomy, and one (2.3%) received both thrombolysis and thrombectomy. Outcomes, 54.8% had a good outcome (mRS 0-2), and 45.2% had dependence/death (mRS 3-6). CONCLUSION: Air passengers with stroke were found to be older with more severe strokes and a higher probability of receiving acute stroke treatment compared to non-passengers. Increased awareness with appropriate and timely recognition and triaging of transit passengers with stroke is warranted.

RESUMO

BACKGROUND: Corneal confocal microscopy (CCM) is a noninvasive, reproducible ophthalmic technique to quantify corneal small nerve fiber degeneration. CCM demonstrates small nerve fiber damage in Parkinson's disease (PD), but its role as a longitudinal biomarker of PD progression has not been explored. OBJECTIVE: The aim of this study was to assess corneal nerve morphology using CCM in relation to disease progression in PD. METHODS: Sixty-four participants with PD were assessed at baseline and at 12-month follow-up. Participants underwent CCM with automated corneal nerve quantification and assessment of Movement Disorder Society Unified Parkinson's Disease Rating Scale, Hoehn and Yahr stage, and Montreal Cognitive Assessment. RESULTS: Corneal nerve fiber density (CNFD), corneal nerve branch density, corneal nerve fiber length, corneal total branch density, and corneal nerve fiber area were significantly lower in participants with PD compared with healthy control subjects. Worsening of Movement Disorder Society Unified Parkinson's Disease Rating Scale part III score over 12 months was significantly greater in participants with a CNFD in the lowest compared with the highest quartile at baseline (mean difference: 6.0; 95% CI: 1.0-10.9; P = 0.019). There were no significant changes in CNFD, corneal nerve branch density, corneal nerve fiber length, corneal total branch density, corneal nerve fiber area, or corneal nerve fiber width between baseline and 12-month follow-up. CONCLUSIONS: CCM identifies neurodegeneration in patients with PD, especially those who show the greatest progression in neurological disability. CCM may be a useful tool to help enrich clinical trials with those likely to exhibit more rapid progression and reduce required sample size and cost of studies. © 2021 The Authors.

RESUMO

BACKGROUND: Anatomically, the subglottic area and the cricoid ring are the narrowest portions of the larynx. To limit the potential for damage related to mucosal pressure injuries from the presence of an endotracheal tube, the cuff should be placed below the cricoid in children. Previously, no clinical or imaging method has been used in real time to determine the exact location of the endotracheal tube cuff after endotracheal intubation. Point-of-care ultrasound may provide an option as a safe and rapid means of visualizing the endotracheal tube cuff and its relationship to the cricoid ring thereby achieving ideal endotracheal tube cuff positioning-below the cricoid. METHODS: In this prospective, nonrandomized trial, point-of-care ultrasound was used following endotracheal intubation in children to evaluate the position of the endotracheal tube cuff in relationship to the cricoid and tracheal rings. After anesthesia was induced and the trachea was intubated, the endotracheal tube cuff and its position in relation to the cricoid and tracheal rings were identified in the longitudinal plane using point-of-care ultrasound. With the patient's neck in a neutral position, the level of the proximal (cephalad) margin of the saline-filled cuff of the endotracheal tube was identified and recorded in relationship to the cricoid and tracheal rings. The ideal position is defined as the cephalad margin of the endotracheal tube cuff below the level of the cricoid. RESULTS: The study cohort included 80 patients, ranging in age from 1 to 78 months. In all patients, the cuff of the ETT, cricoid, and tracheal rings were identified. The cephalad end of the endotracheal tube cuff was found at the level of the cricoid in 16.3% of patients, at the first tracheal ring in 27.5% of patients, at the second tracheal ring in 23.8% of patients, at the third tracheal ring in 17.5% of patients, and at below the fourth tracheal ring in 15% of patients. Initial endotracheal tube cuff position had no significant association with age, height, weight, endotracheal tube size, and endotracheal tube type. CONCLUSION: Point-of-care ultrasound provides a rapid and effective means of identifying the position of the endotracheal tube cuff in relationship to the cricoid ring. The technique may have applications in the perioperative arena, emergency departments, and intensive care units.

RESUMO

AIMS: Diabetic neuropathy (DN) is a "Cinderella" complication, particularly in the Middle East. A high prevalence of undiagnosed DN and those at risk of diabetic foot ulceration (DFU) is a major concern. We have determined the prevalence of DN and its risk factors, DFU, and those at risk of DFU in patients with type 2 diabetes mellitus (T2DM) in secondary care in Qatar. MATERIALS AND METHODS: Adults with T2DM were randomly selected from the two National Diabetes Centers in Qatar. DN was defined by the presence of neuropathic symptoms and a vibration perception threshold (VPT) ≥ 15 V. Participants with a VPT ≥ 25 V were categorized as high risk for DFU. Painful DN was defined by a DN4 score ≥4. Logistic regression analysis was used to identify predictors of DN. RESULTS: In 1082 adults with T2DM (age 54 ± 11 years, duration of diabetes 10.0 ± 7.7 years, 60.6% males), the prevalence of DN was 23.0% (95% CI, 20.5%-25.5%) of whom 33.7% (95% CI, 27.9%-39.6%) were at high risk of DFU, and 6.3% had DFU; 82.0% of the patients with DN were previously undiagnosed. The prevalence of DN increased with age and duration of diabetes and was associated with poor glycaemic control (HbA1c ≥ 9%) AOR = 2.1 (95% CI, 1.3-3.2), hyperlipidaemia AOR = 2.7 (95% CI, 1.5-5.0), and hypertension AOR = 2.0 (95% CI, 1.2-3.4). CONCLUSIONS: Despite DN affecting 23% of adults with T2DM, 82% had not been previously diagnosed with one-third at high risk for DFU. This argues for annual screening and identification of patients with DN. Furthermore, we identify hyperglycaemia, hyperlipidaemia, and hypertension as predictors of DN.

RESUMO

BACKGROUND: Adequate sleep and physical activity have been linked to the overall well-being of both medical and psychiatric patients. Patients with schizophrenia have shown abnormal sleep patterns and decreased physical activity that were linked to their psychopathology and physical health. These phenomena are not studied yet in Arab patients with schizophrenia. The purpose of this study is to study the sleep and exercise patterns in Arab patients with schizophrenia compared with those of healthy controls. METHOD: A total of 99 patients with schizophrenia and 101 controls were recruited. Arabic versions of sleep, exercise, socio-demographic, and clinical questionnaires were administered as well as the validated scales to measure psychopathology, depression, and suicidality in these participants. RESULTS: The majority of patients with schizophrenia slept more than 8 h per day and exercised less when compared with controls. Sleep quality was worse in those with higher depression score and higher suicidality scores were seen in patients with lower sleep duration. Multinomial regression showed that patients with schizophrenia have higher odds of sleeping more than 8 h even after controlling for the intake of antipsychotics, age, gender, smoking status, and other confounding factors. CONCLUSION: Our results showed that Arab patients with schizophrenia are at increased risk of having longer sleep duration with inadequate physical activity, which are correlating with worsening of depressive symptoms and suicidality. Thus, more attention should be paid to the changes in sleep patterns and level of exercise when treating Arab patients with schizophrenia.

RESUMO

BACKGROUND: The widespread use of the internet and other digital resources has contributed to the escalation of plagiarism among medical students and students of other healthcare professions. Concerns were raised by faculty at Weill Cornell Medicine-Qatar (WCM-Q), a branch of Weill Cornell Medicine of Cornell University in New York, who had been observing plagiarism in students' assignments. METHODS: To identify the extent of plagiarism practices and their contributing factors, a two-phase mixed-method research study was conducted, comprising a survey administered in 2013, followed by longitudinal interventions, and a second survey in 2017 to measure the impact of the interventions. RESULTS: By Phase II, overall observed plagiarism incidents per year decreased from 44 to 28%, and the number of faculty who observed no plagiarism incidents increased significantly from 12 to 37%. The faculty concerned about student plagiarism decreased by 33% [53.1 to 20%] between Phase I and Phase II. CONCLUSION: When students are provided with information regarding what constitutes plagiarism and their institution's policy in response to plagiarism incidents, they are less likely to engage in such practices.

RESUMO

BACKGROUND: The aims of Evidence-Based medicine (EBM) are to promote critical thinking and produces better patients' outcome (Profetto-McGrath J, J Prof Nurs Off J Am Assoc Coll Nurs 21:364-371, 2005). Accreditation Council for Graduate Medical Education (ACGME) competencies require trainees to locate, appraise and apply clinical evidence to patients' care. Despite the emphasis that ACGME place on EBM, few organizations provide adequate training in EBM. This is even more critical in regions where medical trainees matriculate from diverse backgrounds of undergraduate medical education, where EBM may not be emphasized nor taught at all. EBM practice has a history of research in the West, however, EBM has not been widely studied in the Middle East. METHODS: Clinicians and trainees at Hamad Medical Corporation (HMC) matriculate from many countries in the Middle East and North Africa (MENA) and Asia. Because trainees in Graduate Medical Education (GME) come to HMC from a variety of geographic backgrounds, it is assumed that they also have a variety of experiences and aptitudes in EBM. To assess trainees EBM attitudes and knowledge in the internal medicine department at HMC in Doha, Qatar, the authors surveyed residents and fellows using a two-part survey. The first part was adapted from the evidence-based practice inventory by Kaper to assess trainees' attitudes and perceptions of EBM. Trainees were also asked to complete the Assessing Competency in Evidence Based Medicine (ACE) tool to evaluate their aptitude in different elements of EBM. The results from the two parts were analyzed. RESULTS: The average score on the ACE tool among the participants was 8.9 (±1.6). Most participants rated themselves as beginners or intermediate in their EBM capabilities. Higher ACE scores were observed from participants with educational background from South Asia, and among those with more favorable attitudes towards EBM. There was no clear pattern that early incorporation of EBM into practice will result in better ACE score. Participants also reported reasonable abilities in EBM tasks and a favorable work atmosphere for EBM implementation. Lack of knowledge, resources, and time were the most reported barriers to utilizing EBM. CONCLUSIONS: While it is clear that participants are enthusiastic about EBM and see it as a useful method for clinical decision making, their aptitude in EBM is not optimal and there are gaps and barriers for them to practice.

RESUMO

Premenstrual dysphoric disorder (PMDD) is not well-studied in Arab populations. The goal of this study was to validate the Arabic version of the Premenstrual Symptoms Screening Tool (PSST) using the DSM diagnosis of PMDD as the gold standard. The PSST was translated and culturally adapted using back translation and the approval of the original author. We recruited 194 adult women (between October 2013 and March 2014) from two primary care centers in Doha, Qatar. A psychiatrist determined the diagnosis using the semi-structured Mini International Neuropsychiatric Interview, and another rater blinded to the diagnosis finalized the Arabic PSST and administered other clinical questionnaires. The data showed that premenstrual symptoms and PMDD were observed in about 37 percent and 15 percent, respectively, of the women enrolled. The mean age of the women with PMDD according to the PSST was about 30 years, and the majority had children. The Arabic PSST showed high specificity of 95.6 percent but low sensitivity of 26.7 percent. A factor analysis of the different items in Arabic PSST showed that the Arabic PSST could detect the cases with definite PMDD and thus can be a useful tool in primary care settings as this treatable disorder is underdiagnosed in the Arab populations.

RESUMO

PURPOSE: To compare diagnostic accuracy of CT-guided fine-needle aspiration biopsy (FNA-B) with positron emission tomography (PET)-CT for pulmonary nodules ≤ 8 mm. MATERIALS AND METHODS: A retrospective review of all CT-guided lung FNA-Bs performed between 2011 and 2014 at a single institution was undertaken to evaluate patients who had FNA-B and PET-CT imaging of nodules of ≤ 8 mm. Patients without surgical pathology or 2-year follow-up CT scans were excluded. Of 1,896 patients, 41 patients with 43 subcentimeter pulmonary nodules met study criteria. The McNemar test was used to compare FNA-B with PET-CT results. RESULTS: FNA-B had a sensitivity and diagnostic accuracy of 88.9% and 81.4%, respectively. PET-CT had an overall sensitivity and diagnostic accuracy of 38.9% and 46.5%, respectively. FNA-B had a significantly higher sensitivity and diagnostic accuracy for malignant nodules compared with PET-CT (P < .001). Pneumothorax rate after FNA-B was 13.9%, and chest tube insertion rate was 0%. CONCLUSIONS: FNA-B is a safe procedure with superior sensitivity and higher diagnostic accuracy compared with PET-CT in pulmonary nodules ≤ 8mm in size.

RESUMO

BACKGROUND: Metabolic abnormalities are common in patients maintained on antipsychotics. These abnormalities increase the risk of cardiovascular diseases and mortality in this population. The aim of this study is to assess the prevalence of metabolic syndrome (MetS) in subjects maintained on antipsychotics relative to controls in Qatar, and to assess the factors contributing to the development of MetS. METHODS: A cross sectional design was used to collect data and fasting blood samples from subjects maintained on antipsychotics for at least six months (n = 112) and from a control group (n = 114). The groups were compared in regard to prevalence of MetS, and multiple regression analysis was used to determine the risk factors in each group. RESULTS: The two groups (antipsychotics vs. control) were similar in regard to age (35.73 ± 10.28 vs. 35.73 ± 8.16 years) and gender ratio. The MetS was higher among the subjects on antipsychotics, but this difference did not reach statistical significance. Blood pressure (BP) was significantly higher in the antipsychotics group and BMI was the major risk factor to develop MetS in this group. CONCLUSIONS: The prevalence of MetS in both groups is high and mostly attributed to obesity and high BP. Public health interventions are needed to address this major health problem overall. Larger studies are needed to further assess the impact of antipsychotics and mental illness on the development of MetS.

RESUMO

PURPOSE: To study the benefit of intravitreal dexamethasone implant in the management of neovascular age-related macular degeneration resistant to bevacizumab and ranibizumab. METHODS: Patients with persistent macular fluid on optical coherence tomography despite monthly treatment with at least three consecutive bevacizumab injections followed by at least three ranibizumab injections were prospectively enrolled. A single dexamethasone implant was administered followed by intravitreal ranibizumab 1 week later. Ranibizumab was continued afterward on an as-needed basis. Main outcomes were improvement in central retinal thickness and best-corrected visual acuity. RESULTS: Nineteen patients (19 eyes) were enrolled. There was no significant change in best-corrected visual acuity over 6 months. Greatest reduction in mean central retinal thickness, from 295.2 µm to 236.2 µm, occurred 1 month after dexamethasone implant (P < 0.0001). By Month 6, mean central retinal thickness was 287.3 µm (P = 0.16). Eyes with only intraretinal fluid (13 eyes) achieved a fluid-free macula. Eyes with predominantly subretinal fluid (6 eyes) did not improve central retinal thickness and continued monthly ranibizumab. Mean baseline intraocular pressure was 13.2 mmHg, which peaked at 15.6 mmHg by Month 2 (P = 0.004). CONCLUSION: Intravitreal dexamethasone implant improved only macular intraretinal fluid in eyes with neovascular age-related macular degeneration resistant to bevacizumab and ranibizumab. However, this treatment had a limited duration.

RESUMO

BACKGROUND: Cigarette smoking is one of the major preventable causes of death and diseases in Qatar. The study objective was to test the effect of a structured smoking cessation program delivered by trained pharmacists on smoking cessation rates in Qatar. METHODS: A prospective randomized controlled trial was conducted in eight ambulatory pharmacies in Qatar. Eligible participants were smokers 18 years and older who smoked one or more cigarettes daily for 7 days, were motivated to quit, able to communicate in Arabic or English, and attend the program sessions. Intervention group participants met with the pharmacists four times at 2 to 4 week intervals. Participants in the control group received unstructured brief smoking cessation counseling. The primary study outcome was self-reported continuous abstinence at 12 months. Analysis was made utilizing data from only those who responded and also using intent-to-treat principle. A multinomial logistic regression model was fitted to assess the predictors of smoking at 12 months. Analysis was conducted using IBM-SPSS® version 23 and STATA® version 12. RESULTS: A total of 314 smokers were randomized into two groups: intervention (n = 167) and control (n = 147). Smoking cessation rates were higher in the intervention group at 12 months; however this difference was not statistically significant (23.9% vs. 16.9% p = 0.257). Similar results were observed but with smaller differences in the intent to treat analysis (12.6% vs. 9.5%, p = 0.391). Nevertheless, the daily number of cigarettes smoked for those who relapsed was significantly lower (by 4.7 and 5.6 cigarettes at 3 and 6 months respectively) in the intervention group as compared to the control group (p = 0.041 and p = 0.018 respectively). At 12 months, the difference was 3.2 cigarettes in favor of the intervention group but was not statistically significant (p = 0.246). Years of smoking and daily number of cigarettes were the only predictors of smoking as opposed to quitting at 12 months (p = 0.005; p = 0.027 respectively). CONCLUSIONS: There was no statistically significant difference in the smoking cessation rate at 12 months between the groups. However, the smoking cessation program led to higher (albeit non-significant) smoking cessation rates compared with usual care. More research should be conducted to identify factors that might improve abstinence. TRIAL REGISTRATION: Clinical Trials NCT02123329 . Registration date 20 April 2014.

RESUMO

BACKGROUND: The Positive and Negative Syndrome Scale (PANSS) is a widely used assessment for patients with schizophrenia across clinical and research settings. This scale allows the classification of the psychotic symptoms to better understand the psychopathology in patients with schizophrenia. There are no available data on the different components of psychopathology in Arab patients with schizophrenia. OBJECTIVES: This study examined the factor structure of the validated Arabic version of the PANSS in a sample of Arab patients with schizophrenia. METHODS: The Arabic version of the PANSS was administered to 101 patients with schizophrenia, and principal component analysis (PCA) was carried out after the cross-cultural adaptation and validation of this version. RESULTS: This sample had more males (66.3%) than females (33.7%) with a mean age of 35.03 years (SD = 9.99). PCA showed that 28 items loaded on 5 components: cognitive, negative, excited, depressed and positive. These factors explained 63.19% of variance. The 2 remaining items, grandiosity and somatic concerns, did not load well on any of these components. CONCLUSION: Our results support the common 5-dimension PANSS model shown in other cultures with different languages. Nevertheless, there were minor differences, which could reflect cultural or semantic differences.

RESUMO

BACKGROUND: In ovarian cancer, the increased rate of radical surgery comprising upper abdominal procedures has participated to improve overall survival (OS) in advanced stages by increasing the rate of complete cytoreductions. However, in the context of non-resectability, it is unclear whether radical surgery should be considered when it would lead to microscopic but visible disease (≤1 cm). We aimed to compare the survival outcomes among patients with incomplete cytoreduction according to the extent of surgery. METHODS: Overall, 148 patients presenting with advanced stage ovarian carcinomas were included in this retrospective study, regardless of treatment schedule. These patients were stratified according to the extent of surgery (standard or radical). Complete cytoreduction at the time of debulking surgery could not be carried out in all cases. RESULTS: Among our study population (n = 148), 96 patients underwent standard procedures (SPs) and 52 underwent radical surgeries (RP). Patients in the SP group had a lower Peritoneal Index Cancer (PCI) at baseline (12.6 vs. 14.9; p = 0.049). After PCI normalization, we observed similar OS in the SP and RP groups (39.7 vs. 43.1 months; p = 0.737), while patients in the SP group had a higher rate of residual disease >10 mm (p < 10(-3)). Patients in the RP group had an increased rate of relapse (p = 0.005) but no difference in disease-free survival compared with the SP group (22.2 for SP vs. 16.3 months; p = 0.333). Residual disease status did not impact survival outcomes. CONCLUSIONS: In the context of non-resectable, advanced stage ovarian cancer, standard surgery seems as beneficial as radical surgery regarding survival outcomes and should be considered to reduce surgery-associated morbidity.

RESUMO

OBJECTIVE: Qatar is a small country on the Eastern coast of the Arabian Peninsula. Its population is a unique mixture of native citizens and immigrants. We aimed to describe the features of epilepsy in Qatar as such information is virtually lacking from the current literature. METHODS: We summarized information retrospectively collected from 468 patients with epilepsy seen through the national health system adult neurology clinic. RESULTS: Epilepsy was classified as focal in 65.5% of the cases and generalized in 23%. Common causes of epilepsy were as follows: stroke (9%), hippocampal sclerosis (7%), infections (6%), and trauma (6%). Sixty-six percent of patients were receiving a single antiepileptic drug, with levetiracetam being the most frequently prescribed drug (41% of subjects). When the patients were divided by geographical background, remote infections caused the epilepsy in 15% of Asian patients (with neurocysticercosis accounting for 10%) but only in 1% of Qatari and 3% of Middle East/North African subjects (with no reported neurocysticercosis) (p<0.001). Cerebrovascular and neurodegenerative etiologies were the most prominent in Qataris, accounting for 14% (p=0.005) and 4% (p=0.03) of cases, respectively. The choice of antiepileptic drugs varied also according to the regional background, but the seizure freedom rate did not, averaging at 54% on the last clinic visit. SIGNIFICANCE: To our knowledge, this is the first detailed information about epilepsy in Qatar. The geographical origin of patients adds to the heterogeneity of this disorder. Neurocysticercosis should be in the etiological differential diagnosis of epilepsy in patients coming from Southeast Asian countries, despite the fact that it is not endemic to Qatar. The choice of antiepileptic drugs is influenced by the availability of individual agents in the patients' native countries but had no bearing on the final seizure outcome.
