Studies of colonialism often associate indirect colonial rule with continuity of the precolonial institutions. Yet, we know less about how colonialism affected the distribution of power between precolonial domestic elites within nominally continuous institutions. We argue that colonial authorities will redistribute power toward elites that are the most congruent with the colonizer’s objectives. We test our theory on the British occupation of Egypt in 1882. Using an original dataset on members of the Egyptian parliament and a difference-in-differences empirical strategy, we show that the colonial authorities shifted parliamentary representation toward the (congruent) landed elite and away from the (oppositional) rural middle class. This shift was greater in cotton-producing provinces which were more exposed to colonial economic interest. Our results demonstrate that the colonial redistribution of power within precolonial institutions can reengineer the social-structural fabric of colonized societies.

I investigate the effects of trade on labor coercion under the dual-coercive institutions of slavery and state coercion. Employing novel data from Egypt, I document that the cotton boom in 1861–1865 increased both imported slaveholdings of the rural middle class and state coercion of local workers by the elite. As state coercion reduced wage employment, it reinforced the demand for slaves among the rural middle class. While the abolition of slavery in 1877 increased wages, it did not affect state coercion or wage employment. I discuss the political effects of the abolition as a potential explanation for these findings.

“The barbarism of the [U.S.] South, while destroying itself, [appeared] in the providence of God to be working out the regeneration of Egypt.”

Camel milk has been consumed for centuries due to its medicinal and healing properties. The present study aims to investigate the consumption patterns of camel milk and perceived benefits and risks among adults in the United Arab Emirates. A self-administered online questionnaire was developed in English and Arabic languages and was completed online by 852 adults. Socio-demographic characteristics, camel milk consumption patterns and perceived knowledge of the benefits and risks of camel milk were investigated. About 60 % of the participants have tried drinking camel milk, but only a quarter (25⋅1 %) were regular consumers. The most consumed camel milk products after fresh milk were yoghurt and flavoured milk. The most popular additions to camel milk were honey, turmeric and sugar. Most consumers had less than one cup of camel milk per day (57⋅0 %). Camel milk consumers preferred it over other types of milk due to its nutritional value (66⋅4 %) and medicinal properties (39⋅3 %). Among consumers, 58⋅4 % reported consuming unpasteurised camel milk. Reasons included the belief that it is fresher (87⋅2 %), better for the immune system (41⋅6 %), and higher in nutrients (39⋅2 %). Overall, participants had inadequate knowledge about the health benefits of camel milk (7⋅11 ± 5⋅3 out of 25). Males and camel milk consumers had a significantly higher knowledge about the health benefits of camel milk compared to females and non-consumers (P < 0⋅05). Although positive perceptions were common, misperceptions appear to be prevalent among non-consumers. Consuming unpasteurised camel milk is a major public health concern, thus national regulations are essential.

The transition of foods during toddlerhood and the suboptimal diets consumed in the Middle East make children susceptible to malnutrition and micronutrient deficiencies. Based on international recommendations, coupled with the merits of clinical studies on the application of young child formula (YCF), a group of fourteen experts from the Middle East reached a consensus on improving the nutritional status of toddlers. The recommendations put forth by the expert panel comprised twelve statements related to the relevance of YCF in young children; the impact of YCF on their nutritional parameters and functional outcomes; characteristics of the currently available YCF and its ideal composition; strategies to supply adequate nutrition in young children and educational needs of parents and healthcare professionals (HCPs). This consensus aims to serve as a guide to HCPs and parents, focusing on improving the nutritional balance in toddlers in the Middle Eastern region. The panellists considere YCF to be one of the potential solutions to improve the nutritional status of young children in the region. Other strategies to improve the nutritional status of young children include fortified cow's milk and cereals, vitamin and mineral supplements, early introduction of meat and fish, and the inclusion of diverse foods in children's diets.

Coronavirus disease 2019 (COVID-19) has rapidly spread globally, forcing countries to apply lockdowns and strict social distancing measures. The aim of this study was to assess eating habits and lifestyle behaviours among residents of the Middle East and North Africa (MENA) region during the lockdown. A cross-sectional study among adult residents of the MENA region was conducted using an online questionnaire designed on Google Forms during April 2020. A total of 2970 participants from eighteen countries participated in the present study. During the pandemic, over 30 % reported weight gain, 6·2 % consumed five or more meals per d compared with 2·2 % before the pandemic (P < 0·001) and 48·8 % did not consume fruits on a daily basis. Moreover, 39·1 % did not engage in physical activity, and over 35 % spent more than 5 h/d on screens. A significant association between the frequency of training during the pandemic and the reported change in weight was found (P < 0·001). A significantly higher percentage of participants reported physical and emotional exhaustion, irritability and tension either all the time or a large part of the time during the pandemic (P < 0·001). Although a high percentage of participants reported sleeping more hours per night during the pandemic, 63 % had sleep disturbances. The study highlights that the lockdown due to the COVID-19 pandemic caused a variety of lifestyle changes, physical inactivity and psychological problems among adults in the MENA region.

The objective of this study was to describe the epidemiology of COVID-19 in Nigeria with a view of generating evidence to enhance planning and response strategies. A national surveillance dataset between 27 February and 6 June 2020 was retrospectively analysed, with confirmatory testing for COVID-19 done by real-time polymerase chain reaction (RT-PCR). The primary outcomes were cumulative incidence (CI) and case fatality (CF). A total of 40 926 persons (67% of total 60 839) had complete records of RT-PCR test across 35 states and the Federal Capital Territory, 12 289 (30.0%) of whom were confirmed COVID-19 cases. Of those confirmed cases, 3467 (28.2%) had complete records of clinical outcome (alive or dead), 342 (9.9%) of which died. The overall CI and CF were 5.6 per 100 000 population and 2.8%, respectively. The highest proportion of COVID-19 cases and deaths were recorded in persons aged 31–40 years (25.5%) and 61–70 years (26.6%), respectively; and males accounted for a higher proportion of confirmed cases (65.8%) and deaths (79.0%). Sixty-six per cent of confirmed COVID-19 cases were asymptomatic at diagnosis. In conclusion, this paper has provided an insight into the early epidemiology of COVID-19 in Nigeria, which could be useful for contextualising public health planning.

Self-selection of converts is an under-studied explanation of inter-religion socioeconomic status (SES) differences. Inspired by this conjecture, I trace the Coptic-Muslim SES gap in Egypt to self-selection-on-SES during Egypt’s conversion from Coptic Christianity to Islam. Selection was driven by a poll tax on non-Muslims, imposed from 641 until 1856, which induced poorer Copts to convert to Islam leading Copts to shrink into a better-off minority. Using novel data sources, I document that high-tax districts in 641–1100 had in 1848–1868 relatively fewer Copts, but greater SES differentials. Group restrictions on apprenticeships and schooling led the initial selection to perpetuate.

This work focuses on the syntheses of Zn-enriched PtZn nanoparticle electrocatalysts by solution combustion for ethanol oxidation reaction (EOR). Analytical techniques of x-ray diffraction, transmission electron microscopy (TEM), scanning electron microscopy, TEM/scanning TEM-energy dispersive x-ray spectroscopy, and x-ray photoelectron spectroscopy are used for the characterization of electrocatalysts. Cyclic voltammetry and chronoamperometry are applied for the electrocatalysis of C2H5OH and stability test in an alkaline medium, respectively. Electrochemical data show that PtZn/C has improved electrocatalytic activity by ~2.3 times compared with commercial Pt/C, in addition to having earlier onset potential and better stability for EOR. The variation of fuel amount in the synthesis has affected crystallite sizes, electronic, and electrochemical properties in electrocatalysts.

Ichthyophthirius multifiliis is a widespread, ciliated protozoan ectoparasite of fish. In the present study, we investigated the effects of metal nanoparticles on the reproduction and infectivity of free-living stages of I. multifiliis. We determined that ~50% of theronts could be killed within 30 min of exposure to either 20 ng mL−1 gold, 10 ng mL−1 silver or 5 ng mL−1 zinc oxide nanoparticles. Silver and zinc oxide nanoparticles at concentration of 10 and 5 ng mL−1 killed 100 and 97% of theronts, respectively and inhibited reproduction of tomonts after 2 h exposure. Gold nanoparticles at 20 ng mL killed 80 and 78% of tomonts and theronts 2 h post exposure, respectively. In vivo exposure studies using rainbow trout (Oncoryhnchus mykiss) demonstrated that theronts, which survived zinc oxide nanoparticles exposure, showed reduced infectivity compared with control theronts. No mortalities were recorded in the fish groups cohabited with theronts exposed to either nanoparticles compared with 100% mortality in the control group. On the basis of the results obtained from this study, metal nanoparticles particularly silver nanoparticles hold the best promise for the development of effective antiprotozoal agents useful in the management of ichthyophthiriosis in aquaculture.

Refugees have high rates of mental health morbidity as a result of conflict. However, their needs for mental healthcare and psychosocial support are often unmet, despite the efforts of professional and humanitarian organisations. The war refugee crisis is a global challenge that needs a global solution. We call on all governments, regional and international organisations to take responsible humanitarian actions to intervene and support people affected by these disasters and for all humanity to unite against the forces of injustice and degradation. The thematic papers in this issue report on the Syrian crisis from a variety of perspectives.

The recent influx of refugees and immigrants to Greece has coincided with the ongoing and deteriorating financial crisis. This situation does not allow the Greek authorities to provide help to the desired extent. Yet, the church, local communities, medical societies and non-governmental organisations are offering good psychosocial support. In parallel with support for refugees it is important to provide support for the citizens of the host country. The rich countries of northern Europe should help the poorer countries of southern Europe cope with the refugees. A number of important declarations on refugee mental health and related issues have been produced recently, including the Anti-war Declaration of Athens.

Public mass modern education was a major pillar of state-led development in the post-Colonial period. I examine the impact of Egypt's transformation in 1951–1953 of traditional elementary schools (kuttabs) into modern primary schools on the Christian-Muslim educational and occupational differentials, which were in favor of Christians. The reform granted kuttabs' graduates (where Muslim students were over-represented) access to higher stages of education that were previously confined to primary schools' graduates. Exploiting the variation in exposure to the reform across cohorts and districts of birth among males in 1986, I find that the reform benefited Muslims but not Christians.

We assessed parental attitudes towards congenital cardiovascular malformations in their children in a cross-sectional study in Egypt. Parents face many problems related to concerns about their child’s prognosis, but these associations with parental stress have never been evaluated in Egypt or examined in relation to religiosity in a predominantly Muslim society. Accordingly, we conducted interviews in Cairo with mothers of 99 sequential infants born with conotruncal heart malformations (cases) and 65 mothers of age-matched controls. The survey assessed healthcare access and usage, knowledge of congenital cardiovascular malformations, religiosity, the Locus of Control Scale, and the Parenting Stress Index. Results showed that 45% of the mothers of cases had correct knowledge about their child’s diagnosis; 85% were satisfied with the clinical care; and 79% reported that the cost of care was burdensome. Compared with parents of cases, parents of controls were more likely to report stress overall and all its subscales. Regarding belief about locus of control over health, God as a determining factor was given the highest endorsement. Mothers in the congenital cardiovascular malformations group reported a higher level of parental locus of control than did those in the control group. The correlations between stress and locus of control were stronger in the control than in the case group. Religiosity was related neither to stress nor to locus of control. Future studies can explore the roles that personal, familial, and societal factors play in exacerbating or reducing stress levels among parents of sick children, particularly in developing countries where economic pressures are acute.

In 1805–1882, Egypt embarked on one of the earliest state industrialization programs. Using a new data source, the Egyptian nineteenth-century population censuses, I examine the impact of the program on the long-standing inter-religious human capital differentials, which were in favor of Christians. I find that there were inter-religious differentials in reaping the benefits (or losses) of industrialization. The first state industrialization wave was “de-skilling” among Muslims but “up-skilling” among Christians, while the second wave was “up-skilling” for both groups. I interpret the results within Lawrence F. Katz and Robert A. Margo (2013) framework of technical change.
