RESUMO

AbstractMycetoma is a chronic soft tissue infection caused by fungal or bacterial pathogens, and is endemic in tropical and subtropical regions. Cases in developed countries outside the mycetoma belt are rare and usually imported by immigrants. Sporadic cases have been reported in Israel. Unpublished cases in the participating medical centers are reported. In addition, a systematic review of the literature was performed. All published mycetoma cases diagnosed in Israel were included with relevant variables collected. Twenty-one cases of mycetoma were diagnosed in Israel between 1942 and 2015, including four unpublished cases and 17 published cases. The mean age at diagnosis was 42 years (range 23-73), and 16 of the patients were male. The foot was the primary involved organ. Fifteen patients were immigrants from Yemen, Ethiopia, and Sudan. Five cases were autochthonous. One case was travel related. Among patients who developed symptoms after immigration, the mean time from exposure to symptom onset was 5.6 years (range 1-10 years). The mean time from symptom onset to diagnosis was 6.6 years (range 0.2-35 years). The autochthonous cases demonstrate that Israel is endemic of mycetoma. The immigrant population represents two distinct waves of immigration to Israel in the past century. Two unpublished cases of Ethiopian immigrants are the first reported cases of mycetoma acquired in Ethiopia. The diagnostic and therapeutic challenges along with the epidemiological data emphasize the need of raising the awareness of physicians to this devastating condition even in developed countries.

RESUMO

BACKGROUND: Fragile and conflict-affected situations (FCS) in Asia and the Middle-East contribute significantly to global maternal and neonatal deaths. This systematic review explored maternal and neonatal health (MNH) services usage and determinants in FCS in Asia and the Middle-East to inform policy on health service provision in these challenging settings. METHODS: This systematic review was conducted using a standardised protocol. Pubmed, Embase, Web of Science, and selected development agency websites were searched for studies meeting inclusion criteria. Studies were assessed for methodological quality using an adapted evaluation tool. Qualitative and quantitative data were synthesized and pooled odds ratios generated for meta-analysis of service-usage determinants. RESULTS: Of 18 eligible peer-reviewed studies, eight were from Nepal, four from Afghanistan, and two each from Iraq, Yemen, and the Palestinian Territories. Fragile situations provide limited evidence on emergency obstetric care, postnatal care, and newborn services. Usage of MNH services was low in all FCS, irrespective of economic growth level. Demand-side determinants of service-usage were transportation, female education, autonomy, health awareness, and ability-to-pay. Supply-side determinants included service availability and quality, existence of community health-workers, costs, and informal payments in health facilities. Evidence is particularly sparse on MNH in acute crises, and remains limited in fragile situations generally. CONCLUSIONS: Findings emphasize that poor MNH status in FCS is a leading contributor to the burden of maternal and neonatal ill-health in Asia and the Middle-East. Essential services for skilled birth attendance and emergency obstetric, newborn, and postnatal care require improvement in FCS. FCS require additional resources and policy attention to address the barriers to appropriate MNH care. Authors discuss the 'targeted policy approach for vulnerable groups' as a means of addressing MNH service usage inequities.

RESUMO

Lifestyle changes occurring with urbanization increase the prevalence of both type 2 diabetes mellitus (T2DM) and hypertension (HTN). Yemenites who have immigrated to Israel have demonstrated a dramatic increase in T2DM but the prevalence of HTN in diabetic Yemenites is unclear. In a cross-sectional study, the authors evaluated the prevalence of HTN and lifestyle patterns in Israelis with T2DM of Yemenite (Y-DM) and non-Yemenite (NY-DM) origin. Y-DM (n=63) and NY-DM (n=120) had similar age (63±7 vs 64±7 years, P=.5), diabetes duration, diet adherence, and exercise patterns. Y-DM had a lower prevalence of HTN (63%) than NY-DM (83%) (P<.01). Furthermore, Yemenite origin was independently associated with lower prevalence of HTN (odds ratio, 0.3; 95% confidence interval, 0.12-0.71). Blood pressure was well controlled with fewer antihypertensive medications in Y-DM than NY-DM (P<.01). Even though lifestyle patterns were similar in the two groups, Y-DM had a lower prevalence of HTN compared with NY-DM and required fewer antihypertensive medications.

RESUMO

Spinocerebellar ataxia type 3 is an autosomal dominant ataxia with various phenotypes affecting Jews of Yemenite origin in Israel. Clinical and family pedigrees data of 125 Yemenite Jewish patients were collected in our clinic. All examined patients underwent a detailed neurological and bedside vestibular examination. Cytosine-adenine-guanine repeats size in the Ataxin-3 gene was measured, and patients with expanded cytosine-adenine-guanine repeats >44 were diagnosed genetically as having spinocerebellar ataxia type 3. We estimated a disease prevalence rate of about 29/100,000 in Jew of Yemenite descendents living in Israel. We were able to group patients into 17 families. Mean age of onset was 44 years. 74 % of our population expressed neurological signs compatible with sub-phenotype III, i.e., ataxia and polyneuropathy. Vestibulo-ocular reflex deficit detected on bedside examination was found in 90 % of the patients. The mean number of cytosine-adenine-guanine repeats in the Ataxin-3 gene of the diseased allele was 67 (range 55-76). Age of onset was inversely correlated with the number of cytosine-adenine-guanine repeats (r = -0.7) and was significantly earlier among male patients. Though the mean number of cytosine-adenine-guanine repeats was not larger in the offspring, their age of onset was significantly earlier than that of their parents. In addition, paternal offspring expressed the disease significantly earlier than maternal offspring. Signs and stages of disease seem to progress slower during the first 10-15 years of the disease and faster afterward. A high disease prevalence rate in our Yemenite Jewish subpopulation is similar to that found in other isolated populations in other countries. Vestibulo-ocular reflex deficit detected on bedside examination should be added as part of the phenotype of Yemenite Jewish patients. Our clinical and genetic findings are in partial agreement with other spinocerebellar ataxia type 3 population studies and are relevant to patient management and the design of further studies.

RESUMO

AIMS: The aim of the current study was to characterize ß-cell function, insulin sensitivity and line of inheritance in patients with recent-onset type 2 diabetes of Yemenite and non-Yemenite Jewish origin. METHODS: A cohort study including 121 GAD negative diabetic patients, 59 of Yemenite and 62 of non-Yemenite origin, treated by diet ± oral antihyperglycemic monotherapy who underwent 180-min meal tolerance test (MMT). Based on MMT, indexes of insulin resistance and secretion were calculated. RESULTS: There were no significant differences in age, sex, diabetes duration, BMI, HbA1c and lipid profile. A significant difference was found in family history of diabetes: 63 % of patients of Yemenite origin had maternal inheritance versus 35 % in the non-Yemenite origin (p < 0.001). Both indexes of ß-cell function, the insulinogenic and the disposition indexes were significantly lower in patients of Yemenite origin compared with non-Yemenite origin (0.66 ± 0.4 vs. 0.93 ± 0.8, p = 0.04; 2.3 ± 1.8 vs. 3.3 ± 3.3, p = 0.04, respectively) with no difference in insulin sensitivity. When females and males were analyzed separately, the difference in maternal inheritance remained significant in both, but the difference in ß-cell function indexes was observed only in males (p = 0.03, p = 0.01, respectively). CONCLUSIONS: Males with recent-onset diabetes of Yemenite origin have a significant reduction of ß-cell function and reduced ability to compensate for insulin resistance compared with diabetic males of non-Yemenite origin. Both males and females of Yemenite origin have a significantly higher maternal inheritance of diabetes. These data suggest different underlying mechanisms leading to early loss of ß-cell in diabetic males of Yemenite origin.

RESUMO

PURPOSE: The purpose of this study was to better understand barriers and facilitators of diabetes self-management education (DSME) among Arab American patients with diabetes. Little is known about the impact of Arab culture on DSME. METHODS: Arab American adults (N = 23) with medically managed diabetes participated in 1 of 3 focus groups. An Arabic-speaking, trained moderator conducted video-recorded sessions. Verbatim Arabic transcripts were translated into English. Transcripts underwent a qualitative content analysis approach. RESULTS: Arab American cultural traditions such as food sharing, religious beliefs, and gender roles both facilitated and at times impeded DSME. Patients also held conflicting views about their interactions with their providers; some participants praised the authoritative patient-physician relationship style while others perceived the gaps in communication to be a product of Arab culture. Participants expressed that lack of available educational and supportive resources are key barriers to DSME. CONCLUSION: Arab American culture affects DSM activities, and culturally sensitive educational resources are lacking. Development of DSME programs tailored to address relevant aspects of Arab culture might improve DSME outcomes in Arab American population.

RESUMO

BACKGROUND AND STUDY AIMS: Arab-Americans (ArA) in Michigan, USA had the lowest colorectal cancer screening (CRCS) in 2008 compared to the state's general population (45.6% vs. 60.8%). The adherence rate and barriers to CRCS have been identified in a previous study; however, these differences have been not examined among ArA from different countries of origin. PATIENTS AND METHODS: Community-based study through a survey filled by 130 Arab-Americans aged ⩾50years. Demographic information and information about CRC screening knowledge were obtained. Responses were compared between the two largest population groups (Lebanese and Yemenis). RESULTS: The majority of the participants (80%) were from Lebanon (52.3%) and Yemen (27.7%). Majority of the Yemenis group have never been screened for CRC (72.2% vs. 27.9%, p<0.001). Majority of the unscreened Yemenis were males (100% vs. 63.2%, p=0.002). Both unscreened groups had similar length of residence in U.S., citizenship status, education level, health insurance and access to primary care physicians. Unscreened Lebanese had a higher family history of CRCS (31.6% vs. 0%, p=0.002). The most common reported barrier for both groups was the misconception that CRCS is not necessary (62% for Yemenis & 42% for Lebanese, p=0.197). Unscreened Yemenis were more unaware about CRCS (46% vs. 11%, p=0.002). CONCLUSION: CRC screening rates vary among Arab-Americans from different countries of origin. Physicians should consider the country of origin when recommending CRC screening to Arab-Americans.

RESUMO

BACKGROUND: Although obesity has been associated with a higher risk for premature death, the sex and ethnic-origin specific body mass index (BMI) levels that are associated with increased mortality are controversial. We investigated the 40-year cumulative all-cause mortality, in relation to the BMI in adult life, among men and women originating from Yemen, Europe/America, Middle East and North Africa, using sex and ethnic-origin specific BMI cut points. METHODS: A random stratified cohort (n = 5710) was sampled from the central population registry and followed since 1969 for vital status. Weight, height and blood pressure were measured, and smoking status was recorded at baseline. BMI was analysed according to conventional categories and according to sex and ethnic-origin specific quintiles. RESULTS: Elevated and significant mortality hazard ratios (HRs) of 1.21 [95% confidence interval (CI) 1.00-1.45] for women and 1.22 (95%CI 1.03-1.44) for men were found for the highest origin-specific BMI quintile. In men, the lowest ethnic-origin specific quintile was also significantly associated with increased mortality (HR of 1.22 95% CI 1.03-1.45), adjusting for age, smoking and blood pressure. Obesity was associated with mortality in non-smokers (HR = 1.29, 95% CI 1.04-1.61 in men and HR = 1.46, 95% CI 1.19-1.79 in women), whereas leanness was associated with mortality only among smoking men (HR = 1.39, 95% CI 1.09-1.77). CONCLUSION: Refinement of BMI categories using country of origin specific quintiles demonstrated significantly increased mortality in the upper quintile in both sexes, while according to the conventional values this association did not prevail in men. We propose the establishment of sex and origin-specific BMI categories when setting goals for disease prevention.

RESUMO

Lactase persistence (LP), the state enabling the digestion of milk sugar in adulthood, occurs only in some human populations. The convergent and independent origin of this physiological ability in Europe and Africa is linked with animal domestication that either had started in both places independently or had spread from the Near East by acculturation. However, it has recently been shown that at least in its southern parts, the population of Arabia not only has a different LP-associated mutation profile than the rest of Africa and Europe but also had experienced an independent demographic expansion occurring before the Neolithic around the Pleistocene-Holocene boundary. In Arabia, LP is associated with mutation -13,915*G and not, as in Europe, with -13,910*T or, as in Africa, with -13,907*G and -14,010*C. We show here that, in Arabia, -13,915*G frequency conforms to a partial clinal pattern and that this specific mutation has likely been spread from Arabia to Africa only recently from the sixth century AD onward by nomadic Arabs (Bedouins) looking for new pastures. Arabic populations in Africa that still maintain a nomadic way of life also have more -13,915*G variants and fewer sub-Saharan L-type mitochondrial DNA haplogroups; this observation matches archaeological and historical records suggesting that the migration of Arabic pastoralists was accompanied by gradual sedentarization that allowed for admixture with the local African population.

RESUMO

This article describes strategies for using a postpartum depression screening tool with women from two immigrant minority populations (from Yemen and from the Punjab region of India). Techniques to maximize success while working with interpreters and with women's unique cultural considerations are presented. Two case studies provide examples of challenges presented and overcome by women from each of these populations.

RESUMO

ETHNOPHARMACOLOGICAL RELEVANCE: Khat is a natural psychostimulant that has pharmacological effects similar to that of amphetamine. The behaviour of khat chewing is embedded within a cultural context. Meanwhile khat chewing is associated with psychological and physiologically burden, as a 'dependence producing' substance. AIMS OF THE STUDY: To assess the applicability of the construct of substance dependence syndrome (DSM-IV, 1994) to khat chewing and to examine psychosocial and behavioural correlates of this syndrome including tobacco use. MATERIALS AND METHODS: A sample of 204 khat chewers was recruited during random visits to khat sale outlets. A face to face interview that assessed socio-demographic, psychosocial dependence, substance dependence syndrome and behavioural characteristics was conducted. Descriptive, exploratory psychometric and multivariate analyses were employed. RESULTS: Approximately a third (31%) of khat chewers reported symptoms consistent with dependence syndrome including increased khat chewing (13%) and cessation attempts (19%) while 17% reported withdrawal symptoms including depression (61%), increase in appetite (74%) and interrupted sleep (58%). Thirty-eight percent reported continued khat chewing despite impacts on their health. Psychometric assessment of the DSM-IV criteria for khat chewing dependence identified two factors; factor 1 consisted of bio-behavioural items and factor 2 withdrawal items, accounting for 67% of the variance and Cronbach's alpha coefficient at 0.78. In multivariate logistic regression modelling, there was an association between intensity of psychological khat dependence (SDS-Khat) and nicotine dependence with the likelihood of exhibiting khat chewing dependence syndrome (p=0.0005, OR=1.51, 95%CI=1.33-1.71; p=0.043, OR=2.87, 95%CI=1.03-7.98, respectively). CONCLUSIONS: The substance dependence syndrome criteria are applicable to khat chewing and associated with increased intensity of nicotine and psychological khat dependence. The applicability of khat dependence syndrome and exploration of its dimensions and associated factors should be extended in future research. Concurrent validation of these findings using specific objective measures for self-report khat chewing is also recommended.

RESUMO

BACKGROUND: The Fagerstrom Test for Cigarette Dependence (FTCD) (formally FTND) is widely used for measuring physical dependence on nicotine. OBJECTIVE: To explore the cross cultural validity and reliability of FTCD amongst Arabic speaker cigarette consumers who chew khat leaf, a stimulant green leaf. METHODS: The psychometric properties of the FTCD were assessed in a subsample (91 regular cigarette smokers) of purposively selected 204 UK-resident Yemeni khat chewers recruited during random visits to khat sale outlets. Data were collected via a structured face-to-face interview. Data analyses included descriptive tests and factor analysis. RESULTS: Two factors were obtained by a principle axis factor analysis and these were termed as urgency of restoring the level of nicotine after abstinence during sleeping and maintaining the level of nicotine during waking. The internal reliability (Cronbach's alpha coefficient) of the whole FTCD is low (.68) as well as for the two subscales (.60) and (.62) respectively. CONCLUSION: The psychometric properties of the Arabic version of the FTCD scale in this sample of Yemeni khat chewers who smoked regularly confirmed what has been established in other cultural settings. The findings of this study have yet to be cross validated amongst other appropriately representative sample of Arabic speakers.

RESUMO

BACKGROUND: The chewing of khat leaf with tobacco smoking amongst Yemenis, Somalis and Ethiopians is reported to impact oral and general health. The health status and particularly dental and medical care attendance of UK-khat chewers has not received attention. This study aimed to explore health status and dental and medical attendance and its associated factors in UK permanently resident Yemeni khat chewers. METHODS: A cross- sectional study with a purposively selected sample of 204 khat chewers was conducted. Data were collected through face to face interviews. Data analysis included descriptive, Chi-square tests and binary logistic regressions. RESULTS: The mean age for this study sample was 44.84 (SD = ±19.70) years and 35% were employed. Forty five percent reported symptomatic medical attendance for self reported health conditions in the last two weeks whilst 44% had symptomatic dental attendance. Higher khat chewing dependency levels associated positively with both symptomatic dental and medical attendance (p = 0.004, OR = 1.14, 95%CI = 1.04-1.25; p = 0.003; OR = 1.16, 95%CI = 1.05-1.29, respectively). Higher social participation levels associated negatively with symptomatic dental attendance (p = 0.034, OR = 0.98, 95%CI = 0.96-0.99) whilst increase in age and self-reported health conditions associated positively with symptomatic medical attendance (p = 0.030, OR = 1.03, 95%CI = 1.01-1.06; p = 0.001, OR = 4.51, 95%CI = 2.02-10.08, respectively). CONCLUSIONS: In this study of khat chewers, a significant proportion reported symptomatic dental and medical attendance. Demographic, psychosocial and self reported general health conditions were associated significantly with dental and medical attendance. Strategies to improve the dental and medical care attendance amongst this group should focus on these and other unexplored underlying factors.

RESUMO

This paper investigates the extent to which entrenched interests of stakeholder groups both maintain water use practice, and may be confronted. The focus is on the agricultural sectors of Yemen and Jordan, where water resource policymakers face resistance in their attempts to reduce water use to environmentally sustainable levels through implementation of water demand management (WDM) activities. Some farmers in both countries that have invested in irrigated production of high-value crops (such as qat and bananas) benefit from a political economy that encourages increased rather than reduced water consumption. The resultant over-exploitation of water resources affects groups in unequal measures. Stakeholder analysis demonstrates that the more 'powerful' groups (chiefly the large landowners and the political elites, as well as the ministries of irrigation over which they exert influence) are generally opposed to reform in water use, while the proponents of WDM (e.g. water resource managers, environmental ministries and NGOs, and the international donor community) are found to have minimal influence over water use policy and decisionmaking. Efforts and ideas attempted by this latter group to challenge the status quo are classified here as either (a) influencing or (b) challenging the power asymmetry, and the merits and limits of both approaches are discussed. The interpretation of evidence suggests current practice is likely to endure, but may be more effectively challenged if a long-term approach is taken with an awareness of opportunities generated by windows of opportunity and the participation of 'overlap groups'.

RESUMO

ETHNOPHARMACOLOGICAL RELEVANCE: Khat chewing amongst the UK communities originating from Yemen and the East African coast is suggested to create dependency through its main stimulant components (cathinone, norephedrine and norpseudoephedrine) on the central nervous system. AIMS OF THE STUDY: To validate self-reported khat chewing behaviours by measuring levels of cathinone, norephedrine and norpseudoephedrine in saliva and to explore their associations with self-reported khat chewing dependency. MATERIALS AND METHODS: Face-to-face interviews were conducted amongst 30 male UK-resident khat chewers. Saliva samples were collected from each participant and high-performance liquid chromatography (HPLC) employed to extract and quantify the levels of the biomarkers. RESULTS: The mean (SD) for cathinone and the composite norephedrine and norpseudoephedrine levels were 33.93 (±39.20) and 29.28 (±26.32)µg/mL respectively. These biomarkers were significantly associated (p≤0.05) with khat chewing dependency. CONCLUSIONS: Validation of self-reported khat chewing is possible. Khat chewing dependency correlates significantly with biomarker levels in saliva. Replication is required.

RESUMO

Although several studies analyzed p53 and mismatch repair (MMR) gene expression separately in oral squamous cell carcinoma (SCC), no reports of combined assessment of both proteins in this cancer. The aim of this study was to investigate the roles of p53 and hMSH2 proteins in oral SCC as well as in oral dysplastic lesions (DL) in Yemen. Immunohistochemistry was used to examine the pattern of expression of p53 and hmsh2 proteins in 70 oral SCC and 21 oral DL obtained from Yemeni patients. p53 Immunoexpression was detected in 24 of the 70 oral SCC (34.3%) and 3 of 21 DL (14.3%) with no significant difference between the two groups. On the other hand, reduced expression of hMSH2 was detected in 26 of the 70 oral SCC (37.1%) and 2 of 21 oral DL (9.5%) with a statistically significant difference (P=0.03). Both proteins were significantly related to the grade of tumor differentiation (P=0.007 and 0.02, respectively). There was an inverse correlation between the levels of p53 and hMSH2 immunoexpression in the oral SCC (r=0.42, P=0.01). This study suggested that p53 may play a role in the early stages of oral carcinogenesis, while hMSH2 may be altered in the late stages. More importantly, the roles of p53 and hMSH2 in oral carcinogenesis seem to be interrelated in the pathogenetic pathway of oral SCC. Such a relationship has not been published previously in this type of cancer and needs to be clarified in future studies.

RESUMO

INTRODUCTION: Khat chewing is often associated with tobacco use with impacts on health. This cross-sectional study aimed (a) to explore and validate aspects of self-reported tobacco smoking and whether objective measures of tobacco smoking differ in different situations among khat chewers who smoked and (b) to assess the social factors correlated with nicotine dependence among khat chewers who smoked regularly. METHODS: This study recruited a purposive sample of 204 U.K. resident Yemeni khat chewers during random visits to Khat sale outlets. Data were collected via a face-to-face scheduled interview. Data analyses included descriptive tests and a hierarchical linear multiple regression. RESULTS: Of 133 self-reported tobacco smokers, 68% were regular smokers with a mean (SD) carbon monoxide (CO) score (20.53 ± 12.12 ppm) and 32% were episodic smokers with a mean (SD) CO score (16 ± 15.66 ppm). Tobacco smoking as an enhancement of the impacts of khat chewing was reported by 65% and 69% of regular and episodic smokers, respectively. In both groups, higher CO scores were recorded during khat chewing. Hierarchical linear multiple regression modeling showed that increases in levels of severity of dependence on khat chewing were correlated positively with increase in levels of nicotine dependence (ß = .27, p = .006, 95% CI = 0.05, 0.29), whereas social participation was correlated inversely (ß = -.34, p = .001, 95% CI = -0.06, -0.02). CONCLUSIONS: In this study, smoking prevalence was high. Smoking increased during khat chewing. Nicotine dependence levels correlated positively with khat dependence levels, while higher social participation reduced nicotine dependence.

RESUMO

OBJECTIVE: To estimate the number of women with female genital mutilation (FGM) living in Belgium, the number of girls at risk, and the target population of medical and social services (MSSs) concerned. METHODS: Data about prevalence of FGM from the most recently published Demographic and Health Surveys and Multiple Indicator Cluster Surveys were applied to females living in Belgium who migrated from countries where excision or infibulation are being practised, and to their daughters. RESULTS: Amongst the 22,840 women and girls living in Belgium who are from a country concerned, 6,260 have 'most probably already undergone a FGM' (women born in the country of origin), and 1,975 are 'at risk' (second generation born in Belgium). The target population of MSSs comprises 1,190 girls less than five years old attending well-baby clinics, 1,690 girls aged 5-19 years attending preventive school health centres, 4,905 women 20-49 years old and 450 women over 50 years of age attending reproductive health services. The population of women concerned is unequally dispersed in Belgium and reflects the distribution of migrant settlement in the different provinces. CONCLUSION: FGM in Belgium requires a more concerted approach in terms of prevention, and medical and social care. Accurate information about the distribution of women concerned should permit better planning of competent services.
