"Hunting Otherwise" : Women's Hunting in Two Contemporary Forager-Horticulturalist Societies.

Although subsistence hunting is cross-culturally an activity led and practiced mostly by men, a rich body of literature shows that in many small-scale societies women also engage in hunting in varied and often inconspicuous ways. Using data collected among two contemporary forager-horticulturalist societies facing rapid change (the Tsimane' of Bolivia and the Baka of Cameroon), we compare the technological and social characteristics of hunting trips led by women and men and analyze the specific socioeconomic characteristics that facilitate or constrain women's engagement in hunting. Results from interviews on daily activities with 121 Tsimane' (63 women and 58 men) and 159 Baka (83 women and 76 men) show that Tsimane' and Baka women participate in subsistence hunting, albeit using different techniques and in different social contexts than men. We also found differences in the individual and household socioeconomic profiles of Tsimane' and Baka women who hunt and those who do not hunt. Moreover, the characteristics that differentiate hunter and non-hunter women vary from one society to the other, suggesting that gender roles in relation to hunting are fluid and likely to change, not only across societies, but also as societies change.

Multidrug-resistant patients receiving treatment in Niger who are infected with M. tuberculosis Cameroon family convert faster in smear and culture than those with M. tuberculosis Ghana family.

In this study, we analyzed the M. tuberculosis complex (MTBc) population structure among multidrug-resistant TB (MDR-TB) patients in Niger and tested whether the Cameroon family displayed a slower response to MDR-TB treatment. We genotyped baseline clinical isolates that had been collected from pulmonary MDR-TB patients recruited consecutively between 2008 and 2016 in Niger. Spoligotyping was used to analyze the genetic diversity of mycobacterial lineages, and Kaplan Meier's analysis to compare treatment outcomes. A total of 222 MTBc isolates were genotyped; 204 (91,9%) were identified as the Euro-American L4 lineage, with the Ghana family (106, 47,4%) and the Cameroon family (63, 28,4%) being predominant. Patients infected by Cameroon family isolates 61(96,8%) showed faster conversion (log-rank p < 0.01) than those infected with Ghana family isolates (91,5%), and were more likely to experience favorable outcome (adjusted odds ratio [aOR] 4.4; 95%CI 1.1-17.9]; p = 0.015). We found no association between MTBc families and second-line drug resistance profiles (p > 0.05). Our findings show that MDR-TB in Niger is caused by major spoligotypes of the Euro-American L4; with more rapid smear and culture conversion in patients infected with the Cameroon family. These first insights may alert clinicians that slow conversion may be associated with the type of infecting strain.

Benign acute viral myositis in African migrants: A clinical, serological, and pathological study.

BACKGROUND: Several viruses have been described as causes of acquired inflammatory myopathies; however, the mechanisms by which they cause muscle disease are still unclear. The aim of this study was to describe the laboratory features of benign acute myositis in a small case series. METHODS: A detailed pathological and serological analysis was performed in five African migrants who developed an acute viral myositis complicated by rhabdomyolysis. RESULTS: Muscle biopsies clearly documented an inflammatory myopathy with histological features similar to polymyositis including CD8+ T cells surrounding and invading nonnecrotic muscle fibers, CD68+ macrophages and major histocompatibility complex class I antigen upregulation. In addition, positivity for myositis-specific antibodies (MSA), in particular anti-aminoacyl tRNA synthetases, was found in the serum of two patients. CONCLUSIONS: Our study demonstrated that T-cell mediated injury occurs in muscle of patients with acute viral myositis, and that MSA may be present in the serum of these patients.

Prevalence of post-traumatic stress disorder, depression and somatisation in recently arrived refugees in Germany: an epidemiological study.

AIMS: Despite recent worldwide migratory movements, there are only a few studies available that report robust epidemiological data on the mental health in recent refugee populations. In the present study, post-traumatic stress disorder (PTSD), depression and somatisation were assessed using an epidemiological approach in refugees who have recently arrived in Germany from different countries. METHODS: The study was conducted in a reception facility for asylum-seekers in Leipzig, Germany. A total of 1316 adult individuals arrived at the facility during the survey period (May 2017-June 2018), 569 of whom took part in the study (N = 67 pilot study and N = 502 study sample; response rate 43.2%). The questionnaire (11 different languages) included sociodemographic and flight-related questions as well as standardised instruments for assessing PTSD (PCL-5), depression (PHQ-9) and somatisation (SSS-8). Unweighted and weighted prevalence rates of PTSD, depression and somatisation were presented stratified by sex and age groups. RESULTS: According to established cut-off scores, 49.7% of the respondents screened positive for at least one of the mental disorders investigated, with 31% suffering from somatisation, 21.7% from depression and 34.9% from PTSD; prevalence rates of major depression, other depressive syndromes and PTSD were calculated according to the DSM-5, which indicated rates of 10.3, 17.6 and 28.2%, respectively. CONCLUSIONS: The findings underline the dramatic mental health burden present among refugees and provide important information for health care planning. They also provide important information for health care systems and political authorities in receiving countries and strongly indicate the necessity of establishing early psychosocial support for refugees suffering from psychological distress.

Social Networks and Knowledge Transmission Strategies among Baka Children, Southeastern Cameroon.

The dynamics of knowledge transmission and acquisition, or how different aspects of culture are passed from one individual to another and how they are acquired and embodied by individuals, are central to understanding cultural evolution. In small-scale societies, cultural knowledge is largely acquired early in life through observation, imitation, and other forms of social learning embedded in daily experiences. However, little is known about the pathways through which such knowledge is transmitted, especially during middle childhood and adolescence. This study presents new empirical data on cultural knowledge transmission during childhood. Data were collected among the Baka, a forager-farmer society in southeastern Cameroon. We conducted structured interviews with children between 5 and 16 years of age (n = 58 children; 177 interviews, with children being interviewed 1-6 times) about group composition during subsistence activities. Children's groups were generally diverse, although children tended to perform subsistence activities primarily without adults and with same-sex companions. Group composition varied from one subsistence activity to another, which suggests that the flow of knowledge might also vary according to the activity performed. Analysis of the social composition of children's subsistence groups shows that vertical and oblique transmission of subsistence-related knowledge might not be predominant during middle childhood and adolescence. Rather, horizontal transmission appears to be the most common knowledge transmission strategy used by Baka children during middle childhood and adolescence, highlighting the importance of other children in the transmission of knowledge.

Waiting for the Second Treat: Developing Culture-Specific Modes of Self-Regulation.

The development of self-regulation has been studied primarily in Western middle-class contexts and has, therefore, neglected what is known about culturally varying self-concepts and socialization strategies. The research reported here compared the self-regulatory competencies of German middle-class (N = 125) and rural Cameroonian Nso preschoolers (N = 76) using the Marshmallow test (Mischel, 2014). Study 1 revealed that 4-year-old Nso children showed better delay-of-gratification performance than their German peers. Study 2 revealed that culture-specific maternal socialization goals and interaction behaviors were related to delay-of-gratification performance. Nso mothers' focus on hierarchical relational socialization goals and responsive control seems to support children's delay-of-gratification performance more than German middle-class mothers' emphasis on psychological autonomous socialization goals and sensitive, child-centered parenting.

Relationship Between Subjectively Evaluated Health and Fear of Death Among Elderly in Three Cultural Contexts.

It is often argued that declining health in elderly people makes death more salient and threatening. However, we argue that health, optimism, and social support interact to predict fear of death in samples from Cameroon, the Czech Republic, and Germany. Low health was associated with enhanced fear of death for participants who received only little social support. As the measure of optimism did not comply with psychometric requirements in the Cameroonian sample, the three-way interaction was tested only in the Czech and German samples. It was found that the two-way interaction was further qualified by optimism in that low health was associated with enhanced fear of death for participants with little social support unless they reported pronounced optimism. Thus, internal and external resources, respectively, can serve to buffer the effect of declining health on the fear of death in the elderly.

Infants' Social Experiences in Three African Sociocultural Contexts.

This study introduces a peri-urban context of poverty to the study of child development in Africa in contrast to the more typical assessments in middle-class and rural contexts. Spot observations were used to assess universal caregiving behaviors toward seventy-six 3-month-old infants. Results show that middle-class infants experienced distal parenting behaviors instantiated by mothers, whereas rural children experienced proximal parenting practices in interactions with others. Infants growing up in poverty had mothers and other caretakers involved at mostly low levels. They experienced low levels of body contact, body stimulation, and object stimulation, and high levels of face-to-face positions. The study indicates that caregiving in the context of poverty does not necessarily follow familiar pathways and needs to be contextualized accordingly.

Sexual Abuse in Cameroon: A Four-Year-Old Girl Victim of Rape in Buea Case Study.

A young girl was brought to the emergency unit after suffering sexual abuse by an older male. Additional abuses against women and girls include physical beating, forced marriage, female genital mutilation, breast ironing, widow's rites, psychological abuse, and discrimination in education, finance, employment, and legal access. Cameroon has adopted strategies aimed at eliminating violence against women, including ratification of international policies, penal codes, and support of local and international efforts that promote women; however, many of the laws remain in name only and are rarely enforced, given women's lack of financial access to quality lawyers and an unsympathetic male-dominated police force. Underreporting and culturally accepted abuses remain a challenge, too, as the country seeks to understand the extent of abuses and how to effectively fight against them. A complete paradigm shift in cultural attitude toward the female gender is required for abuses to cease.

Children's Family Drawings as Expressions of Attachment Representations Across Cultures: Possibilities and Limitations.

The present study explored the cross-cultural appropriateness of children's family drawings as a measure for attachment quality. The sample consisted of 63 children aged 6 years from two diverse ecosocial contexts: middle-class families from Berlin, Germany (n = 32) and rural farming families from small villages around Kumbo, Cameroon (n = 31). The analysis of drawings with two classical attachment procedures, the Checklist of Drawing Signs (Kaplan & Main, 1986) and the Global Rating Scales (Fury, 1996), revealed substantial cultural differences. The results thus substantiated children's drawings as important cultural documents. Implications of the findings, however, are discussed in consideration of culture-specific conceptions of attachment relationships as indicated by cultural variations in mother's socialization goals.

Implicit Racial Biases in Preschool Children and Adults From Asia and Africa.

This research used an Implicit Racial Bias Test to investigate implicit racial biases among 3- to 5-year-olds and adult participants in China (N = 213) and Cameroon (N = 257). In both cultures, participants displayed high levels of racial biases that remained stable between 3 and 5 years of age. Unlike adults, young children's implicit racial biases were unaffected by the social status of the other-race groups. Also, unlike adults, young children displayed overt explicit racial biases, and these biases were dissociated from their implicit biases. The results provide strong evidence for the early emergence of implicit racial biases and point to the need to reduce them in early childhood.

Is Perceptual Priming Affected by Culture? A Study With German Middle-Class and Cameroonian Nso Farmer Children.

The authors explored priming in children from different cultural environments with the aim to provide further evidence for the robustness of the priming effect. Perceptual priming was assessed by a picture fragment completion task in 3-year-old German middle-class and Cameroonian Nso farmer children. As expected, 3-year-olds from both highly diverging cultural contexts under study showed a priming effect, and, moreover, the effect was of comparable size in both cultural contexts. Hence, the children profited similarly from priming, which was supported by the nonsignificant interaction between cultural background and identification performance as well as the analysis of absolute difference scores. However, a culture-specific difference regarding the level of picture identification was found in that German middle-class children identified target as well as control pictures with less perceptual information than children in the Nso sample. Explanations for the cross-cultural demonstration of the priming effect as well as for the culturally diverging levels on which priming occurs are discussed.

Ethnobotanical survey of medicinal plants used for pregnant women׳s health conditions in Menoua division-West Cameroon.

ETHNOPHARMACOLOGICAL RELEVANCE: In Cameroon, most women use traditional medicine for the treatment of pregnancy and childbirth complaints. In order to identify some of the medicinal plants locally used to alleviate these complaints, an ethnobotanical survey was undertaken in five villages of Menoua Division (West-Cameroon). MATERIALS AND METHODS: Interviews were conducted through structured questionnaires among 24 traditional healers and 179 women living either in the town of Dschang or in 4 neighboring villages. After having recorded the interviewee personal information on issues related to medicinal plants utilization, a literature investigation on their therapeutic or pharmacological effects and phytochemical composition was conducted. RESULTS: A total of 88 medicinal plants species used to treat 24 conditions occurring during or after pregnancy and belonging to 70 genera or 34 families were recorded. Maximum medicinal uses of plants are reported for the treatment of the following ailments: swelling of legs and ankles (23%), facilitation of delivery (22%), cleaning of the baby (12%). Most herbal remedies are prepared with the leaves (30%), leaves+stems (28%) and whole plant (23%) as maceration (76%). The majority of women who used medicinal plants were very satisfied (75 %) and it is reported that most of these plants are used in the treatment of women health conditions. CONCLUSION: Many herbal remedies used for the treatment of pregnant women׳s health conditions in Menoua division-West Cameroon have been revealed. It would therefore be judicious for our government and research institution to evaluate the therapeutic and toxicological potentials of these plants in order to valorize their use.

Ritual tooth modification among the Baka pygmies in Cameroon.

INTRODUCTION: Ritual tooth mutilation is a relatively understudied human body mutilatory practices. The purpose of the study was to examine the effects of ritual tooth modification, teeth cleaning measures and herbal medications for their oral health problems among the Baka pygmies in Cameroon. MATERIALS AND METHODS: This cross-sectional study was conducted between January and March, 2012 using semi-structured questionnaire as the tool of data collection. Intra-oral examinations were carried out to determine the dental hard tissue loss using Smith and Knight Tooth Wear Index (TWI). RESULTS: Fifty-six pygmies with ritual tooth modification made of 34 males (60.7%) and 22 females (39.3%) with a mean age of 31 years were interviewed and had oral health examination. The reported age at which the tooth modification was done was between 10 and 15 years with mean age as 12 ± 1.66 years. More than half (58.9%) of the participants reported the tooth filing as painful and nearly two-thirds (64.3%) of the participants reported having persistent pain afterwards. The upper right central and lateral incisors were the most commonly modified teeth. A total of 42.9%, 12.5% and 7.1% of the participants had Smith and Knight TWI scores of 2, 3 and 4 respectively. All the participants reported cleaning their teeth at least once-daily with about two-thirds (66.1%) of them doing so with chewing stick. The majority (67.9%) of the participants reported cleaning their teeth for cosmetic reasons [to remove dirt' (60.7%) and 'to remove stains' (7.1%)]. The oral health problems among the participants in form of tooth sensitivity, toothache and dental abscess were treated with plant-based traditional medicines from Irvingia gabonensis, Ricinodendron heudoletti, Pterocarpus soyauxii, Alchornea cordifolia and Piptadeniastrum africanum. CONCLUSION: Ritual tooth modification is a painful mutilatory practice which is culturally significant for the Baka pygmies without health benefit. There is need for intervention to stop this harmful traditional practices among the pygmies. Further studies is recommended to elucidate the medicinal and pharmaceutical benefits of plants used for tooth sensitivity and other oral health problems by the pygmies.

Determinants of fructosamine levels in a multi-ethnic Sub-Saharan African population.

BACKGROUND AND PURPOSE: Fructosamine provides an estimate of diabetes control over a shorter period than HbA1c, and has been proposed as a suitable parameter to monitor glycemic control in low-income countries. The aim of this study was to investigate determinants of fructosamine levels in an urban non-diabetic population of Cameroon. METHODS: This was a cross-sectional study including 437 healthy adults with no known history of diabetes mellitus, aged 40 years and above, recruited from the ten administrative regions, representing major ethnic groups in the country. Plasma glucose and fructosamine were measured after an overnight fasting. Univariable and multivariable analyses were used to investigate the factors associated with fructosamine measurements. RESULTS: Fructosamine levels ranged from 68.2 to 940.8 µmol/l with a mean (standard deviation) of 294.4 (131.3) µmol/l. These levels varied significantly across regions and were higher in men than in women (p=0.001) and in those with screen-detected diabetes than in those with normoglycemia (p<0.0001). There was a negative correlation between fructosamine and body mass index (r=-0.15, p=0.009), and a positive correlation with fasting plasma glucose (FPG) (r=0.37, p<0.0001) and total bilirubinemia (r=0.21, p<0.0001). In multivariable model, sex, BMI, FPG, total bilirubine and screen-detected diabetes were no longer associated with fructosamine levels. CONCLUSION: Fructosamine was not independently associated with age, sex, ethnicity, and the glycemic status. Further studies need to be carried out to better elucidate all the factors determining the measurement of fructosamine in order to accurately interpret its values in diabetic populations.

"Passing children" and precarious pathways: on the contingency of reproductive life courses in Cameroon.

This article explores the implications of reproductive mishaps for the life courses of women in eastern Cameroon. Based on 15 months of anthropological fieldwork in a Gbigbil village, it describes local ideas about the expected unfolding of physical and social life trajectories, and the ways in which reproductive losses jeopardize these anticipated pathways. The life history of one informant shows that repeated child death can create a paradoxical situation in which a woman feels, at the same time, physically old and socially young, and that decisions for the future are informed by these contradictory sensations. The particular dynamics brought about by reproductive loss, then, challenge common views of the life course as a predefined pathway through consecutive and clearly defined life stages. Instead, they reveal that reproductive biographies are contingent and unpredictable, and that life stages may be paradoxically congruent rather than mutually exclusive. This, in turn, affects the way in which women give direction to their precarious reproductive pathways.

Epilepsy and cysticercosis in Northwest Cameroon: a serological study.

PURPOSE: The prevalence of epilepsy in Cameroon is higher than that of the industrialized world and other developing countries. Neurocysticercosis due to Taenia solium infestation has been reported as a major cause of epilepsy in some parts of Cameroon although there are some conflicting data. The prevalence of epilepsy is especially high in the Momo division of the North-West Province of Cameroon. We hypothesized that individuals with epilepsy in this region have a higher percentage of seropositivity to T. solium than matched controls. METHODS: We conducted a case-control study in the Momo subdivision of Ngie. Individuals with epilepsy were recruited from the health centers in Ngie. Control subjects were selected from 19 Ngie villages. Potential cases of people with epilepsy (PWE) were identified through a questionnaire applied by trained field workers, using history of epileptic seizures as a key indicator. Blood samples were taken from all consenting individuals by finger prick, stored in StabilZyme Select, and assayed for antibodies to T. solium in an Atlanta based reference laboratory. RESULTS: We accrued 249 patients with epilepsy, of whom 237 met the inclusion criteria, and 245 age-matched controls. There was no significant difference in seropositivity to T. solium between those individuals with epilepsy (5%) and controls (4.9%). CONCLUSIONS: Our data do not support the hypothesis that epilepsy is associated with seropositivity to T. solium. It is highly unlikely that cysticercosis plays a causative role in the high prevalence of epilepsy in this region of Cameroon.
