Hemoglobin C and hemoglobin O-Arab variants can be diagnosed using the Bio-Rad Variant II high-performance liquid chromatography system without further confirmatory tests.

CONTEXT: Current standards for laboratory accreditation from the College of American Pathologists state that when high-performance liquid chromatography (HPLC) is used as a screening test, all non-A, non-S abnormal hemoglobin (Hb) variants must be confirmed by an alternative method, including alkaline and acid electrophoresis. OBJECTIVE: To determine whether confirmation of Hb C and Hb O-Arab variants by an alternative method is required when using the Bio-Rad Variant II HPLC system. DESIGN: We reviewed 48 478 consecutive hemoglobin identification test results performed on the Bio-Rad Variant II HPLC system during the period November 15, 2000 to January 15, 2003. SETTING: Special Hematology Laboratory, Department of Pathology, Bellevue Hospital Center, New York, NY. MAIN OUTCOME MEASURES: The chromatogram patterns and retention times (RTs) for specimens containing Hb C and Hb O-Arab were analyzed. We compared the results by the HPLC method with those by the confirmatory tests (alkaline and acid electrophoresis) for both variants. RESULTS: We identified 3668 cases of abnormal hemoglobin variants, including 660 cases of Hb C trait (17%), 5 cases of Hb O-Arab trait (0.1%), and 1 case of Hb SO-Arab (0.03%). A unique pattern of separation on the chromatogram for Hb O-Arab was revealed, presenting as 2 distinct peaks in 2 different manufacturer-defined RT windows, namely, D and C. The chromatogram for Hb C did not show the D window in any of the reviewed cases. The RT in the C window (C-RT) revealed a statistically significant difference for Hb C and Hb O-Arab (5.18 +/- 0.01 minutes and 4.91 +/- 0.01 minutes, respectively; P <.001). CONCLUSION: According to our review, the identification of Hb C and Hb O-Arab is accurate using HPLC methodology, as performed by the Bio-Rad Variant II HPLC system. This method can be both confirmatory and diagnostic at the same time.

Translating medical journals into Arabic. JAMA Middle East as an example.

JAMA Middle East has distributed monthly 25,000 issues into 14 Arab countries since 1991. Translating the original articles into Arabic was considered as the license permits translation. The number of Arab physicians exceeds 250,000, but those who studied medicine in Arabic are very few. Adequate translators and other publishing staff are lacking. Advertisers will not invest in journals without readership. The other 13 international editions of JAMA publish in their national languages, so do their medical schools. Teaching medicine in a foreign language did not bring leadership to Arab medicine. It is just another indicator of Arab underdevelopment. There is growing support to shift the language of medical teaching into Arabic, but the only practical step has been the Unified Medical Dictionary.

[Pharmacy and the great contribution of Arab-Islamic science to its development].

The differentiation and separation of two scientific disciplines, medicine and pharmacy begins during the 12th century. Each differentiation by itself brings certain improvement and upgrading but at any level, this happens only when proper conditions are met. Therefore, in order for pharmacy to appear as a profession and to promoted to the level of science, certain conditions had to be met, namely the society and cultural forces had matured to the level of differentiation of these two disciplines, which have begun existing as completely independent disciplines in that time. For the history of pharmacy, it is very important to note the fact that we find the first beginnings of professional pharmacy among Arabic population. The first drug stores in the world were established in Arabic world (Baghdad 754). Considering the fact that Arabs had brought a great deal to pharmaceutical science and the fact that their search included some 2.000 substances, the goal of this work was formulated and medicinal herbs used in the treatment listed. The forms used that period are still used in the therapy and some formulations of drugs can be found in pharmacopeas even today. If we add to these reports the fact that most of the literature appearing in the field was also of Arabic origin and that many editions and translations of the pharmaceutical works from Arabic to Latin had been published ever since, the obvious contribution of Arabic science in the development of pharmacy becomes even more obvious.

A community study on emotional distress among Arab and Jewish Israelis over the age of 60.

BACKGROUND: The elderly constitute a vulnerable group for psychopathology, yet research on their mental health among both Arab and Jews in Israel remains limited. The same is the case in Arab countries. This paper reports on the contrasting distribution of the mean emotional distress (ED) scores and rates of suspected clinical cases, and their related risk factors, among community residents over the age of 60. METHODS: Several national agencies conducted a survey on 5,055 elderly individuals to investigate their health status, including ED. The interview included socio-demographic and behavioral health items, as well as a modified 12 item-GHQ as a measure of ED. Total ED scores and prevalence rates for suspected psychopathology were calculated. Their respective risk factors were examined using univariate and multivariate methods. RESULTS: The ED scores were highest among Muslim Arabs (4.9), followed by Christian Arabs (4.2), Jews (3.1) and Druzes (2.8). Their estimated prevalence rates were 43.4%, 37.0%, 21.4%, and 17.0%, respectively. The gradient of these results remained unchanged in the multivariate analysis for ED scores adjusting for confounding variables. In contrast, logistic regression analysis controlling for confounding variables did not find a differential risk for suspected psychopathology between Arabs and Jews. CONCLUSION: Conceivably, the higher demoralization scores among elderly Arabs are associated with their minority status affiliation, as well as with the rapid social changes that have taken place in their midst. A cultural response style may be entertained as a possible explanation. However, these factors do not impact the risk for suspected psychopathology where no differential risk was noted after adjustments for confounders.

Identification of intestinal bacteria responsible for fermentation of gum arabic in pig model.

Acacia spp. produce gum exudates, traditionally called gum arabic or gum acacia, which are widely used in the food industry such as emulsifiers, adhesives, and stabilizers. The traditional gum arabic is highly variable with average molecular weights varying from 300,000-800,000. For this reason a standardized sample was used for the present experiments, based on a specific species of gum arabic (Acacia(sen)SUPER GUMEM2). The literature indicates that gum arabic can be fermented by the intestinal bacteria to short chain fatty acid, particularly propionate. However, the bacteria responsible for the fermentation have not been determined. In this study, we used enrichment culture of pig cecal bacteria from the selected high molecular weight specific gum arabic of (M(W )1.77 x 10(6)). We found Prevotella ruminicola-like bacterium as a predominant bacterium that is most likely to be responsible for fermentation of the gum arabic used to propionate.

Arab Americans, African Americans, and infertility: barriers to reproduction and medical care.

OBJECTIVE: To compare barriers to infertility care among African Americans and Arab Americans. DESIGN: Qualitative study using semi-structured reproductive histories and open-ended ethnographic interviews. SETTING: Infertile volunteers in a private IVF clinic in Dearborn, Michigan, an Arab American ethnic enclave community in metropolitan Detroit. PATIENT(S): Arab American men presenting for infertility diagnosis and treatment, including assisted reproductive technologies. INTERVENTION(S): None. MAIN OUTCOME MEASURE(S): Perceived barriers to effective infertility care. RESULT(S): Arab Americans and African Americans living in metropolitan Detroit are at increased risk of infertility and share similar histories of poverty, racism, and cultural barriers to medical treatment. This study, which focused on infertile Arab American men living in or near Dearborn (an ethnic enclave community composed mainly of recent immigrants and war refugees), revealed significant barriers to effective infertility care, including economic constraints, linguistic and cultural barriers, and social marginalization in mainstream U.S. society, particularly after September 11, 2001. CONCLUSION(S): Arab Americans experience disparities in access to infertility care, largely because of poverty and social marginalization in post-September 11th America.

The healthcare experiences of Arab Israeli women in a reformed healthcare system.

UNLABELLED: Arab Israeli women are subject to unique social stresses deriving from their status as part of an ethno-political minority and from their position as women in a patriarchal community. Collectively, their health profiles rate poorly in comparison to Jewish Israeli women or to women in the vast majority of developed countries. OBJECTIVES: To examine the experiences of Arab Israeli women in the contemporary Israeli healthcare system, following implementation of the National Health Insurance Law (NHIL). METHODS: The study combined quantitative and qualitative research methodologies. A telephone survey utilizing a structured questionnaire was conducted during August-September 1998 among a random national sample of 849 women, with a response rate of 83%. Between the months of January and July of 2000, qualitative data was attained via participant-observation, long and short semi-structured interviews, and focus groups in one large Muslim Arab Israeli village. FINDINGS: Arab Israeli women in the national survey reported poorer self-assessed health, lower rates of care by a woman primary care physician, lower satisfaction ratings for primary care physicians and more frequently foregoing medical care than did native or immigrant Jewish Israeli women. Three major factors contributing to Arab Israeli women's healthcare experiences were elucidated by the qualitative study: (1) the threat of physical and social exposure (2) difficulties in communicating with male physicians and (3) the stifling effect of family politics and surveillance on healthcare. DISCUSSION: We discuss our findings in relation to structural changes associated with the recent reform of the Israeli health care system. We conclude by suggesting policy measures for better adapting primary care services to the needs of Arab Israeli women, and note the relevance to other systems that aim to provide service to cultural and ethno-political minorities, in which healthcare delivery is shaped by unique local circumstances.

Self-reported health as a cultural health determinant in Arab and Jewish Israelis MABAT--National Health and Nutrition Survey 1999-2001.

Subjective health (SH) status serves as a measure of health in many studies of health-related issues as it is a good predictor of mortality, morbidity, and use of health services. The measure is used in many population groups. However, the degree to which it measures the same condition in different ethnic groups is not clear. Within Israel's first National Health and Nutrition Survey (MABAT) conducted during 1999-2001, face-to-face interviews were held with 3222 Israeli interviewees, 2379 Jews and 843 Arabs, aged between 25-64 years. Respondents reported their SH, co-morbidity, and other socioeconomic characteristics. Arabs reported higher levels of SH than Jews. In logistic regression analysis, co-morbidity was a much stronger correlate of poorer SH in the Arab than in the Jewish population. The association between socioeconomic variables depended on ethnic group and sex. The findings indicate that SH in Jews and Arabs does not necessarily have the same meaning in relation to objective measures of health, and caution should be exercised in the use of this measure in different population groups with different cultures. Arabs tend to evaluate health better than Jews even though life expectancy is lower and morbidity and mortality are higher in the former population group. Yet diagnosis of a disease increases the frequency of reporting lower SH, more in Arabs than in Jews.

Affinity chromatography of two sets of isomeric antibodies having specificity for different oligosaccharide units of gum arabic.

Two sets of antibodies directed against different carbohydrate units of gum arabic were isolated from the sera of rabbits immunized intramuscularly with gum arabic and Freund's complete adjuvant. The isolation was effected by affinity chromatography on two columns attached in series and containing an absorbent of AH-Sepharose 4B with ligands of partially hydrolyzed gun arabic in the first column and an adsorbent of AH-Sepharose 4B with ligands of native gum arabic in the second column. The two populations of anti-gum arabic antibodies were obtained and have been designated as Set 1 and Set 2 on the basis of their mobilities on agar diffusion. The antibodies of Set 1 consisted of 4 isomeric antibodies and those of Set 2 consisted of 11 isomeric antibodies. Native gum arabic samples were oxidized with periodate or reduced with sodium borohydride and carbodiimide under standard conditions and the modified samples were totally inactive in the precipitin test. On the basis of methylation data and immunological results it was concluded that terminal disaccharide moieties of the gum having the structure beta-D-glucosyluronic acid-(1----6)-D-galactose and alpha-L-arabinofuranosyl-(1----4)-D-glucuronic acid were the immunodeterminant groups for Set 1 and Set 2 antibodies, respectively.

Juvenile ECG pattern in adult black Arabs.

A juvenile electrocardiographic (ECG) pattern is compatible with T wave inversion in the precordial leads V1 and V2 or in additional precordial leads to the left of V2. Electrocardiographic studies were performed in 48 Semitic Arabs, including 26 men and 22 women, and in 50 black Arabs (negroid Bedouins), including 22 men and 28 women. The subjects ranged in age from 20 to 46 years. The juvenile ECG pattern was found in 6 of the 28 black Arab women (21%), but it was not detected in the 22 black Arab men or in any Semitic Arabs of either sex. The difference between the two female groups was significant (P < .05). Careful interpretation of ECG recordings in black Arab women is recommended in order to prevent a misdiagnosis of myocardial ischemia or a misreading of T wave inversions related to a previous coronary event.

Nursing care of Arab children: consideration of cultural factors.

As the number of Arabs living in the United States increases, so does the number of children of Arab descent seeking medical attention. However, despite the sizable and ever increasing number of American Arabs, their health beliefs and practices remain relatively unexplored. When cultural differences exist with regard to beliefs about health and illness, health practices, and health-seeking behavior, the process of health-related interaction becomes difficult and often detrimental to health outcomes. Among Arab immigrants, their children tend to be the least visible population. This article describes the beliefs and practices, both cultural and health-related, of Arab families, with an emphasis on child care and rearing. Nursing considerations, which take these cultural factors into account, are discussed that will accommodate the needs of Arab children receiving professional Western medical treatment.

Effect of partial replacement of gum arabic with carbohydrates on its microencapsulation properties.

Gum arabic solutions (10% w/v) were emulsified with soy oil at oil/gum ratios of 0.25-5.0. At oil/gum ratios <1.0, it was established that gum arabic could be partially replaced with a nonsurfactant carbohydrate. To assess different carbohydrates as replacers for gum arabic, emulsions and spray-dried emulsions of soy oil and mixed solutions (10% w/v) of gum arabic and a range of carbohydrate wall materials (oil/gum = 0.5) were prepared and analyzed. Maize starch and glucose were ineffective as partial replacers of gum arabic, but maltodextrins of various dextrose equivalence values (5.5-38) successfully replaced 50% of the gum arabic. The microencapsulation efficiency of the gum arabic/maltodextrin stabilized powders was further increased by increasing total solids of the feed to the dryer and by increasing the atomizer nozzle diameter.

The development of immunoassays to identify and quantify species source of gum arabic.

Gum arabic from Acacia senegal is commonly used as an additive in foodstuffs. Adulteration of gum arabic by other gums is a potential problem for reasons of safety and quality. This study aimed to develop and evaluate the use of enzyme-linked immunosorbent assays (ELISAs) for the detection of potential adulterants of gum arabic. Indirect competitive ELISAs (IC-ELISAs) were developed using the monoclonal antibodies SY CC7 (A. senegal), SY HH3 (Acacia seyal), and SY J1A1 (Combretum erythrophyllum). All IC-ELISAs had a working range of 0.005-10 mg/mL. The antibodies used were tested using the IC-ELISAs for cross-reactivity with other Acacia species and other gums. The antibodies were very specific for their respective antigens. Significant cross-reactivity was found for SY CC7 (between A. senegal and A. melliferae) and SY J1A1 (between C. erythrophyllum and A. seyal). The IC-ELISA was adapted further to test confectionery samples for the presence of gum arabic, which was successful, although recovery rates were reduced. Both IC- and plate trapped antigen ELISA (PTA-ELISA) formats were able to distinguish an adulterated sample of gum arabic when blended with either A. seyal or C. erythrophyllum. The PTA-ELISA was more sensitive for A. seyal than the IC-ELISA, but both were equally sensitive for C. erythrophyllum. The results suggest that the antibodies SY CC7, SY HH3, and SY J1A1 could be used in combination with each other for the detection of potential adulterants of A. senegal and the detection of gum arabic in foodstuffs.

Substance abuse studies and prevention efforts among Arabs in the 1990s in Israel, Jordan and the Palestinian Authority--a literature review.

This paper is the result of a collaborative project of Israeli, Jordanian and Palestinian scientists gathered to reveal the current extent of substance abuse and efforts at prevention among Arabs in Israel, Jordan and the Palestinian Authority territories, in order to identify needs and suggest future collaborative activities and directions for regional cooperation. The article provides data and covers the current state of substance abuse prevention and research among Moslems, Christians and Druze in the trilateral region in the 1990s by reviewing prevention materials and studies published in the professional literature, as well as in reports and Doctoral and Master's theses in Arabic, which have been located in academic libraries and other institutions, in the framework of a comprehensive search. This manuscript is the first to summarize Jordanian and Palestinian findings in the substance abuse domain. The review shows that most of the Israeli research in the Arab sector deals with alcohol use among youth, that the majority of Jordanian studies focus on illicit drug use, that the research among Palestinians is in its infancy, and that comprehensive prevention programs are lacking in the trilateral region. It describes the key results of most of the 12 Israeli studies among Arabs, 11 Jordanian studies and four Palestinian studies. It reveals that drug abuse among Israeli Arab students is probably more prevalent than among Jewish adolescents, that the typical Jordanian drug addict has a higher level of education than the typical Palestinian drug addict, and that the Palestinian is more likely to be a multiple drug user. Recommendations for future activities include organization of a regional collaborative workshop in order to establish data collection systems for basic statistics relevant to drug abuse and development of comprehensive prevention programs, as well as studies in the substance abuse domain concerning knowledge, attitudes and behavior among the general Arab population.

Gum arabic (Acacia senegal): unambiguous identification by 13C-NMR spectroscopy as an adjunct to the Revised JECFA Specification, and the application of 13C-NMR spectra for regulatory/legislative purposes.

The JECFA Specification for gum arabic was revised in 1990 to reflect more closely the specification of the Test Article used in evaluations that led to its classification 'ADI not specified' in 1982/83. Some producers and traders have objected to the Revised Specification; in contrast, consumer-protection groups consider that it remains too lax to provide the degree of safety assurance expected. This paper presents analytical data that confirm the mean values previously established for nitrogen and the specific rotation of bulk commercial gum arabic from Acacia senegal. The data also establish that natural gum arabic imported into the USA and Europe in 1989/91 met the Revised Specification, but that a disturbingly high proportion of spray-dried, processed gums sold as 'gum arabic' did not. NMR spectroscopy has (a) indicated that some such samples are based on non-permitted gums and (b) confirmed that the 1983 Test Article represents not only typical 1990/91 shipments but also a wide range of reference gum arabic samples from other reputable sources. Details of a representative 13C-NMR spectrum, derived by averaging the relative intensities for the characteristic resonances of 35 gum arabic samples, are given for future regulatory/legislative purposes. Some limitations of the Revised Specification and its susceptibility to commercial exploitation are discussed.

A comparison of the physicochemical and immunological properties of the plant gum exudates of Acacia senegal (gum arabic) and Acacia seyal (gum tahla).

The physiochemical and immunological properties of three Sudanese gum arabic samples and four gum tahla samples (two Sudanese, one West African and one Tanzanian--Acacia seyal var. seyal) were compared. The optical rotation (ca -30 degrees) and rhamnose (12-14%), arabinose (24-29%), galactose (36-42%), glucuronic acid (16-17%), nitrogen (0.327-0.365%) and protein (2.16-2.41%) contents of the gum arabic samples were consistent with the FAO (1990) specification for Acacia gum. In contrast the gum tahla samples had positive [alpha]D values (+45 degrees to +54 degrees), lower rhamnose (3-4%) and higher arabinose (41-45%) contents and lower nitrogen (0.147-0.175%), and hence protein (0.97-1.15%), contents. All of the gum arabic samples precipitated with beta-glucosyl Yariv reagent and hence were shown to contain arabinogalactan-protein(s) (AGPs), whereas in all but one of the gum tahla samples AGPs were not detected. The strong interaction of gum tahla with a monoclonal antibody known to recognize arabinose residues present in AGPs and arabinogalactans (AGs) was consistent with the observed higher levels of arabinose present in the gum tahla samples relative to the gum arabic samples. The data presented confirm that there are a number of physicochemical and structural differences between gum arabic (A. senegal gum) and gum tahla (A. seyal gum), and that a quick and simple immunological technique (immunodot blots) using an antiAGP/AG monoclonal antibody (MAC 207) could be used to screen for the presence of gum tahla in gum arabic consignments.

Does gum Arabic have an antioxidant action in rat kidney?

Gum Arabic has recently been claimed to be effective in preventing gentamicin-induced acute renal failure in rats. The nephroprotection was suggested to be due to an anti-oxidant action by the gum Arabic. In the present work we tested whether treatment with gum Arabic has any effect on the concentrations of some free radical scavengers [reduced glutathione (GSH), ascorbic acid (AA), lipid peroxidation (LP), and superoxide dismutase (SOD)] in the kidneys and liver of healthy rats given gum Arabic in the drinking water at a concentration of 2.5, 5.0 or 10.0% w/v for eight consecutive days. Twenty-four hours after the last treatment, rats were killed and the above variables were measured in homogenates of kidney and liver by established spectrophotometric methods. The results indicated that the gum Arabic, at the three doses used, did not significantly affect any of the variables measured. It seems highly unlikely that gum Arabic has a palliative effect on renal failure through an antioxidant mechanism.

The Arab community in Israel coping with intellectual and developmental disability.

The Arab family in Israel is still embedded in the traditional society with extended family support systems, but we see a population in transition influenced by the surrounding society. This paper looks at the different religious attitudes toward the exceptional people in our society (i.e., the family reaction to a child born with intellectual or developmental disability), reviews recent studies on the Arab and Bedouin families in Israel, and presents data on the Arab population in residential care centers. Today, out of 57 residential care centers in Israel for persons with intellectual disability, 13 (22.8%) are providing service to the non-Jewish population. The Arab population constitutes 12-13% of the total residential care population, lower than the 19-20% in the total population. In residential care, the Arab population is characterized by younger children with severe and profound intellectual disability. The informal family support system is still a very important factor in the Arab family in Israel, a fact that we believe should be strengthened by implementing the British and Danish model of nurse home visitation.
