Factor structure and reliability of the Arabic adaptation of the Hypomania Check List-32, second revision (HCL-32-R2).

OBJECTIVE: To assess the psychometric properties of the Arabic adaptation of the Hypomania-Check-List 32-item, second revision (HCL-32-R2) for the detection of bipolarity in major depressive disorder (MDD) inpatients suffering a current major depressive episode (MDE). METHOD: The "Bipolar Disorders: Improving Diagnosis, Guidance, and Education" Arabic module of the HCL-32-R2 was administered to mother-tongue Arabic MDE inpatients between March 2013 and October 2014. Diagnostic and Statistical Manual Fourth edition (DSM-IV) diagnoses were made adopting the mini-international neuropsychiatric interview, using bipolar disorder (BD) patients as controls. RESULTS: In our sample (n=500, of whom, BD-I=329; BD-II=70; MDD=101), using a cut-off of 17 allowed the HCL-32-R2 to discriminate DSM-IV-defined MDD patients between "true unipolar" (HCL-32-R2(-)) and "sub-threshold bipolar depression" (HCL-32-R2(+)) with sensitivity=82% and specificity=77%. Area under the curve was .883; positive and negative predictive values were 93.44% and 73.23% respectively. Owing to clinical interpretability considerations and consistency with previous adaptations of the HCL-32, a two-factor solution (F1="hyperactive/elated" vs. F2="irritable/distractible/impulsive") was preferred using exploratory and confirmatory factors analyses. Item n.33 ("I gamble more") and n.34 ("I eat more") introduced in the R2 version of the HCL-32 loaded onto F1, though very slightly. Cronbach's alphas were F1=.86 and F2=.60. LIMITATIONS: No cross-validation with any additional validated screening tool. Inpatients only sample; recall bias; no systematic evaluation of eventual medical/psychiatric comorbidities, current/lifetime pharmacological history, or record of severity of current MDE. CONCLUSIONS: In our sample, the HCL-32 fairly discriminated between MDD and BD-I but not BD-II, therefore soliciting for replication studies for use in Arabic-speaking depressed inpatients.

Prevalence of ischemic and hemorrhagic strokes in Qena Governorate, Egypt: community-based study.

BACKGROUND: Stroke is a major health problem in developing countries. In a previous survey, the prevalence rate of stroke in the Nile Valley governorate of Assiut was significantly higher than other Arabic countries. In view of this, we carried out a follow-up study in a second Nile Valley governorate (Qena). METHODS: A community-based, three-phase, door-to-door study with random sampling of 10 areas in Qena governorate (first phase), involving 8027 inhabitant with 4172 males (51.97%) and 3855 females (48.03%). There were 4427 urban residents (55.15%) and 3600 residents (44.85%) from the rural community. In the second phase, participants were screened using the questionnaire for stroke, whereas the third phase involved neurologic evaluation of all suspected cases, with diagnosis of stroke confirmed by evaluation of computed tomography (CT) scans. The Mini Mental State Examination and National Institute of Health Stroke Scale were evaluated for each patient. RESULTS: Of the 8027 participants, 74 were identified as positive cases with a crude prevalence rate 922 of 100,000, an age-adjusted local prevalence rate of 777 of 100,000 and an age-adjusted prevalence rate of Egyptian population 566.6 of 100,000. The highest age-specific prevalence rates were recorded among subjects 70 years of age or older (8,392 of 100,000). The crude prevalence rate of ischemic stroke was significantly higher than that of hemorrhagic stroke (797 vs 125 of 100,000). Illiterate participants had a significantly higher crude prevalence rate than those who were literate (3567 vs 704 of 100,000). There was no significant difference in the prevalence rate between rural and urban areas or between males and females. Fifty patients (67.57%) had 1 or more risk factors of stroke, with hypertension being the most common (62.16%), followed by diabetes mellitus (36.49%). CONCLUSIONS: The overall prevalence rate of stroke is nearly the same as in other Egyptian governorates and is higher than other Arabic countries.

Prevalence of mild cognitive impairment and dementia among the elderly population of Qena Governorate, Upper Egypt: a community-based study.

BACKGROUND: There are only a few reports which provide prevalence rates of mild cognitive impairment (MCI) and dementia specifically in Arabic countries. OBJECTIVE: This study is aimed at estimating the prevalence of MCI and dementia among subjects aged ≥60 years using door-to-door survey in Qena Governorate/Egypt. METHODS: We conducted a door-to-door survey with multistage probability random sampling. Screening of all subjects aged ≥60 years (n = 691) employed a simple questionnaire including changes in memory, behavior, and daily activity, Memory and Executive Screening test (MES)as well as the Mini-Mental State Examination. Suspected cases were referred to the hospital for full clinical examination, DSM-IV diagnostic criteria, Hachinski Ischemic Score, neuroimaging, and laboratory investigations if indicated. RESULTS: Of the 691 participants, 12 cases had MCI, giving a crude prevalence rate (CPR) of 1.74/100 and 35 were identified as positive for dementia with a CPR of 5.07/100. The highest age-specific prevalence rates were recorded among subjects ≥85 years old (100/100). The CPRs were significantly higher in urban than rural areas (7.1 versus 3.27/100, respectively; p = 0.03), in industrial areas than non-industrial areas (13.23 versus 1.99; p = 0.00001), and in illiterate than literate participants (10.12 versus 2.25/100; p = 0.00001). CONCLUSION: Overall, the prevalence rate of MCI and dementia were lower in Qena/Egypt than in other countries. Advanced age, illiteracy, and living in an industrial area were found to be associated with dementia.

Prevalence of Parkinsonism and Parkinson's disease in Qena governorate/Egypt: a cross-sectional community-based survey.

BACKGROUND AND PURPOSE: In a previous study we found a high crude prevalence rate (CPR) for Parkinson's disease (PD) in Assiut governorate/Egypt. We therefore surveyed a second Nile valley governorate (Qena) to provide confirmatory evidence for the high prevalence rate of PD in Egypt. SUBJECTS AND METHODS: 10 areas in Qena governorate were selected by random sampling to recruit 8027 inhabitants. Positive cases were identified using a modified screening questionnaire, the unified Parkinson disease rating scale (UPDRS), mini-mental state examination (MMSE) and the non-motor symptoms scale (NMSS) for PD. RESULTS: Forty-four patients were identified with Parkinsonism, giving a CPR of 548/10(5) inhabitants. Among them, 35 patients were diagnosed as PD with CPR of 436/10(5); three cases were diagnosed as drug-induced Parkinsonism with CPR 37/10(5); two cases had atherosclerotic Parkinsonism with CPR 25/10(5).Age-specific CPR of PD among population aged ≥ 50 years old was 2534/10(5).The highest age-specific CPR was recorded among subjects ≥ 75 years old. The CPR showed a tendency to be higher in males than females, urban than rural areas and industrial than non-industrial areas (503 vs 363/10(5), 474 vs 389/10(5) and 655 vs 312/10(5), respectively). There was a significantly higher CPR among illiterate than literate persons (1982 vs 299/10(5) with P = 0.00001). About one quarter of patients had cognitive impairment. All cases had positive symptoms in at least one or more NMS Domains. CONCLUSION: The overall prevalence of PD disease is high in Nile valley governorates of Upper Egypt compared to other Arabic countries.
