Is Cam Morphology Found in Ancient and Medieval Populations in Addition to Modern Populations?

BACKGROUND: Cam morphology is thought to originate near puberty and reflects a response of the peripheral aspect of the proximal femoral physis to increased local load. Participation in particular sports activities has been associated with cam morphology in contemporary patient populations; however, it is unclear whether cam is a recent phenomenon. There are limited data regarding the frequency of its occurrence and the general deviations in femoral anatomy in different historical populations. Such information may help to understand the possible influence of lifestyle and diet on cam morphology. QUESTIONS/PURPOSES: The purpose of this study was to evaluate femoral morphology in three historical populations. We asked: (1) Was cam morphology present in the three study populations, did those populations differ, and were there differences between sexes? (2) Were there differences in neck-shaft angle, version, or inclination between and among the examined populations? METHODS: We examined 204 adult femurs from the Neolithic population from Iran (n = 37, 3000 BC to 1631 BC), medieval population from Poland (n = 135, 10th to 13th centuries), and contemporary Australian aborigines (n = 32, early 20th century), provided by the Open Research Scan Archive, Museum of the First Piasts at Lednica and the University of Wroclaw, respectively. All three human populations represent different chronologic periods and lifestyles. All bones were scanned using CT and then measured on their three-dimensional (3-D) reconstructions in selected planes. Cam impingement was defined as an alpha angle > 55° measured on the inclination view. To evaluate the differences in anatomy between populations, we measured the true neck-shaft angle on the true AP view, apparent neck-shaft angle on the apparent AP view, the version angle on the version view, and the inclination angle on the inclination view. The prevalence of cam morphology and other anatomic parameters were compared among groups using chi-square test, one-way ANOVA with post hoc Tukey test, and paired t-test. RESULTS: Cam morphology was present in 5% of the Neolithic population from Iran, in 7% of the medieval population from Poland, and 3% of the contemporary Australian aborigine femurs (OR Neolithic population from Iran/the medieval population from Poland 0.7 [95% CI 0.2 to 3.4]; p = 0.67; OR Neolithic population from Iran/contemporary Australian aborigines 1.8 [95% CI 0.2 to 20.5]; p = 0.65; OR the medieval population from Poland/contemporary Australian aborigines 2.5 [95% CI 0.3 to 20.1]; p = 0.40). There were differences in the presence of cam morphology between the sexes in the medieval population from Poland with both femurs (females: 1% [1 of 76]; males: 15% [9 of 59]; p = 0.002). There was a difference in true neck-shaft angle between the Neolithic population from Iran (121° ± 6°) and contemporary Australian aborigines (131° ± 5°; mean difference 10° [95% CI 7° to 13°]; p < 0.001) and between the medieval population from Poland (124° ± 5°) and the contemporary Australian aborigines (mean difference 7° [95% CI 5° to 9°]; p < 0.001). Apparent neck-shaft angle differed between the Neolithic population from Iran (126° ± 6°) and the contemporary Australian aborigines (134° ± 5°; mean difference 8° [95% CI 6° to 11°]; p < 0.001), and between the medieval population from Poland (126° ± 6°) and the contemporary Australian aborigines (mean difference 9° [95% CI 7° to 11°]; p < 0.001). Moreover, we observed a difference in the version angle between the Neolithic population from Iran (19° ± 7°) and the medieval population from Poland (12° ± 9°; mean difference 7° [95% CI 4° to 10°]; p < 0.001] and in the inclination angle between aforementioned groups (18° ± 7° versus 11° ± 8°; mean difference 7° [95% CI 5° to 10°]; p < 0.001). CONCLUSION: This study found that cam morphology existed in historical populations at rates comparable with a contemporary population. CLINICAL RELEVANCE: The presence of cam morphology in historical populations suggests that cam morphology can develop outside of the intense sports activity seen in modern adolescents. Further study will help elucidate the etiology of cam morphology, which may be useful in the development of preventive strategies.

Historical and modern research on propolis and its application in wound healing and other fields of medicine and contributions by Polish studies.

ETHNOPHARMACOLOGICAL RELEVANCE: The history of medical application of propolis (also known as bee glue) dates back to the times of ancient Greeks, Romans, Persians and Egyptians. Honey and other bee products, including propolis, occupy an important place in Polish folk medicine. Scientific research on propolis in Poland began in the early 1960s in Zabrze and continues until now. AIM OF THE REVIEW: The aim of this review is to provide an overview of information on Polish research on propolis and its medical application with particular emphasis on studies concerning wound healing. Consequently, our goal is also to shed a new light on therapeutic potential of Polish propolis in order to support future research in the field. MATERIALS AND METHODS: A systematic review of scientific literature on propolis and its medical application was performed by using the literature databases (PubMed, Web of Science, Google Scholar). We paid special attention to papers describing the effect of propolis on skin wound healing as well as to Polish contribution to research on propolis. RESULTS: Professor Stan Scheller was the first Polish scientist dealing with propolis and its medical potential. His legacy was continued by several research teams that studied the topic in various aspects. They analyzed propolis composition, its antioxidant, anti-inflammatory, antimicrobial, antiapoptotic and anticancer properties as well as its application in dentistry and wound treatment. Burn wound healing physiology after propolis administration was thoroughly studied on pig model, whereas research on patients proved the efficacy of propolis in chronic venous leg ulcer treatment. CONCLUSION: Polish scientists have made a significant contribution to the research on propolis, its biological properties and influence on wound healing. Propolis ointments can effectively accelerate the healing process and improve healing physiology, so they can be recommended as a promising topical medication for wound treatment in the future clinical and preclinical trials.

Talking about intimate partner violence in multi-cultural antenatal care: a qualitative study of pregnant women's advice for better communication in South-East Norway.

BACKGROUND: Intimate partner violence (IPV) against women constitutes a major public health problem. Antenatal care is considered a window of opportunity to disclose and to communicate about IPV. However, little is known about how women from different ethnic backgrounds wish to communicate about their experiences with IPV during pregnancy in antenatal care. The aim of the present study was to explore how women from different ethnic backgrounds experienced IPV and what their recommendations were about how midwives should communicate about IPV in antenatal care. METHODS: Qualitative individual interviews with eight women who had experienced IPV during pregnancy were conducted and analysed using thematic analysis. The participants were purposively recruited from three crisis shelters in South-East Norway. RESULTS: The participants either had immigrant backgrounds (n = 5) or were ethnic Norwegians (n = 3). All participants received antenatal care by a midwife. Although none of the participants were asked about IPV during antenatal care, they wished to talk about their experiences. Most participants felt that it would be important for the midwife to make them aware that they were victims of violence. Participants offered different suggestions on how and when midwives should talk about IPV. Facilitators to talk about IPV with the midwife were a good relationship with and the trustworthiness of the midwife, information about possible negative health outcomes for the newborn owing to IPV and knowing that the midwife could help them. The main barriers to talk about IPV with the midwife were that the participants were accompanied by their husbands during antenatal care, fear that the Child Welfare Service would take away their children after disclosure and cultural acceptance of violence. Participants with immigrant backgrounds also experienced difficulties in talking about IPV owing to their limited language skills. They thought that professionally trained interpreters with experience of IPV could overcome this barrier. CONCLUSION: Even though none of the participants were asked about IPV in antenatal care, they offered different suggestions on how and when midwives should talk about IPV. Participants irrespective of their ethnical backgrounds perceived antenatal care as a key area to facilitate disclosure of IPV. Midwives' communication and strategic skills to address IPV are crucial for help-seeking women. Training midwives' skills in culture-sensitive communication might help to overcome cultural barriers to talk about violence.

Medicinal Plant Diversity and Inter-Cultural Interactions between Indigenous Guarani, Criollos and Polish Migrants in the Subtropics of Argentina.

Numerous studies highlight the importance of phytotherapy for indigenous and non-indigenous people in different parts of the world. In this work we analyze the richness (number of species), diversity (plant identity and the number of illnesses for which it is used) and similarity of plant species and illnesses treated with them, in order to contribute new data and insight into the importance of plant medicines to the local medical systems of people living in Misiones province, in the subtropics of Argentina. Three sympatric groups were compared: Guarani Indians, Criollos (mestizos) and Polish migrants. Quantitative scrutiny was focused on both primary and secondary sources. The similarity and diversity of medicinal plants and uses between groups was calculated by applying the Sørensen quantitative coefficient and the Shannon-Wiener index, respectively. In order to identify the characteristic plant species used by each group, the Cultural Importance and Prevalence Value (CIPV) was calculated based on the species Indicator Value (IndVal), which combines a species relative abundance with its relative frequency of occurrence in the various groups, and modified according to the type of the analyzed data. The important finding is a great variation in the number of species used by the study groups. Altogether, 509 botanical species were registered: Guarani (397), Criollos (243) and Polish migrants (137). For all groups, the use of native medicinal plants prevailed. The Guarani appear to be the local experts in use of medicinal plants. There is the significant difference in the number of treated illnesses by each taxon among three groups. Criollos and Polish migrants exhibit the greatest similarity in illnesses treated with medicinal plants. These groups share a corpus of knowledge related to illness nosology, and have a symptomatic approach to illness treatment. The Guarani have an etiological approach to illness diagnosis and healing, which may be viewed as a barrier to the exchange of knowledge about home medicine with other ethnic groups of Misiones.

Forms of medical pluralism among the Polish Community in Misiones, Argentina.

The paper addresses forms of medical pluralism, studied from the microsocial perspective, among the Polish community in Misiones, Argentina. It shows different attitudes to health treatment within the field of home medicine, local non-biomedical specialists and biomedicine. It points out the relationship between the diversity of offers of medical assistance and community members' negotiations between various medical approaches. It also identifies the factors influencing these choices. While prior research examines Indigenous and Mestizo medical ethnobotany in this region, there has not been research on medical pluralism and very little study of complementary and alternative medicine among the inhabitants of Misiones. The study group comprises Polish peasants who settled in northern Misiones between 1936 and 1938 and their descendants born in Argentina. Field research was based on semi-structured, in-depth and free-listing interviews. The analysis was carried out using both qualitative and quantitative approaches. The results show that Polish settlers tried to reconstruct bits and pieces of their familiar and traditional healing practices in the new environment. Phytotherapy plays the most important role among home therapies. It is at home that most treatments start. Members of the Polish community also treat folk illnesses at home and report them to local healers. The growing influence of biomedicine does not contribute to the elimination of home medicine or non-biomedical specialists in the study area. There has been a medicalization of childbirth and fractures, but folk experts such as curanderos, hueseros and naturistas are still very popular in the region.

Biomedical practices from a patient perspective. Experiences of Polish female migrants in Barcelona, Berlin and London.

This paper focuses on the diversity in patients' experience of bio-medicine and contrasts it with the normative view characteristic of health professionals. Ethnographic fieldwork among Polish migrant women in London, Barcelona and Berlin included interviews about their experiences with local healthcare and health professionals. Themes drawn from the narratives are differences between the cities in terms of communication between patients and health professionals, respect for patients' choices and dignity, attitudes to pregnancy and birth (different levels of medicalization), and paediatric care. It is argued that patients continuously negotiate among their own views and expectations based on previous experiences and knowledge from personal communication; internet forums and publications; and the offer of medical services in the countries of their settlement. Patients experience pluralism of therapeutic traditions within and outside bio-medicine. In turn, representatives of bio-medicine are rarely aware of other medical practices and beliefs and this leads to various misunderstandings. By highlighting the pluralism of medical practices in European countries and the increasing mobility of patients, this case study has useful implications for medical anthropologists and health professionals in a broader Western context, such as raising sensitivity to different communication strategies and a diversity of curing traditions and expectations.

Management of medicinally useful plants by European migrants in South America.

ETHNOPHARMACOLOGICAL RELEVANCE: Using the example of Polish migrants living in the subtropics of Argentina, we attempt to expand knowledge about migrant strategies for retaining their agency in medicinal plant procurement. AIM OF THE STUDY: Is to state which environments play a pivotal role as a source of medicinal plants for the study community, and if a gradient of relevance exists in the exploitation of medicinally useful species between the most proximate and the most distant habitats. We particularly aim to answer the following questions: (1) if Polish migrants have changed their patterns of obtaining medicinal plants during the migratory process; and (2) if the choice of strategies for medicinal plants depends on: (a) the degree of floristic and environmental similarity between the home and host country; (b) the perception and usefulness of certain environments as a source of medicinal plants; (c) the degree of contact with the local population in the host country, and/or (d) the degree of contact between migrants and their homeland. MATERIAL AND METHODS: The analysis is grounded in data from different types of interviews and a homegarden inventory addressed to 72 study participants. Voucher specimens of species mentioned were gathered and identified. Two indices were used as proxy measures: (1) the number of species obtained from each habitat, and (2) the number of citations for both modes and places of obtaining medicinal plants. RESULTS: Due to different flora found in Argentina, Polish migrants could reconstruct only bits and pieces of their native pharmacopoeia. They could not acquire medicinal plants either from relatives in Poland or via importation. Therefore they had to develop new strategies for securing medicinal resources. During the migratory process, Poles in Misiones changed forms and places of obtaining medicinal plants. Cultivated species from homegardens play the most important role, while in the native country homegarden species were used sparsely. The second most important environment for medicinal plant procurement is the forest, whose exploitation was increased by contact with local mestizos and indigenous groups. CONCLUSIONS: This study clearly shows that traditional knowledge can be adaptive and resilient. New species have been selected and incorporated from mestizos, and indigenous people, and at the same time the use of some legacy plants has been preserved. The importance of home gardens as a venue for medicinal plants is another facet of this adaptive process. Traditional knowledge is resilient too, because despite the many changes that have occurred, Polish people have maintained phytotherapy as their preferred form of treating ailments, and managed to retain certain species brought from Europe as the most relevant.

Between the Baltic and Danubian Worlds: the genetic affinities of a Middle Neolithic population from central Poland.

For a long time, anthropological and genetic research on the Neolithic revolution in Europe was mainly concentrated on the mechanism of agricultural dispersal over different parts of the continent. Recently, attention has shifted towards population processes that occurred after the arrival of the first farmers, transforming the genetically very distinctive early Neolithic Linear Pottery Culture (LBK) and Mesolithic forager populations into present-day Central Europeans. The latest studies indicate that significant changes in this respect took place within the post-Linear Pottery cultures of the Early and Middle Neolithic which were a bridge between the allochthonous LBK and the first indigenous Neolithic culture of north-central Europe--the Funnel Beaker culture (TRB). The paper presents data on mtDNA haplotypes of a Middle Neolithic population dated to 4700/4600-4100/4000 BC belonging to the Brzesc Kujawski Group of the Lengyel culture (BKG) from the Kuyavia region in north-central Poland. BKG communities constituted the border of the "Danubian World" in this part of Europe for approx. seven centuries, neighboring foragers of the North European Plain and the southern Baltic basin. MtDNA haplogroups were determined in 11 individuals, and four mtDNA macrohaplogroups were found (H, U5, T, and HV0). The overall haplogroup pattern did not deviate from other post-Linear Pottery populations from central Europe, although a complete lack of N1a and the presence of U5a are noteworthy. Of greatest importance is the observed link between the BKG and the TRB horizon, confirmed by an independent analysis of the craniometric variation of Mesolithic and Neolithic populations inhabiting central Europe. Estimated phylogenetic pattern suggests significant contribution of the post-Linear BKG communities to the origin of the subsequent Middle Neolithic cultures, such as the TRB.

Plants used as food and medicine by Polish migrants in Misiones, Argentina.

In this article we discuss the importance of food plants, both introduced and native, in the pharmacopoeia of the Polish community in Misiones, Argentina. Food species constitute a relevant portion of all botanicals used by Polish settlers in home therapies (41%), while introduced food species prevail among the continued herbal remedies used by the study group. We explain this pattern of use by food plant availability, their versatility as reflected in the number of medicinal applications, and also their importance in cross-cultural relations. Finally, we conclude that several food plants used by Polish migrants (e.g., Allium sativum, Mentha xpiperita, and Camellia sinensis) may have served to "strengthen" migrants' identity within the host country.

Comparing of nutrients content and calorific value in the diets of Poles and Greeks living in Athens.

BACKGROUND: Diet is generally defined as a set of behaviors, on the choice of certain foods, their consumption, and it is conditioned by various factors. Each model is shaped feeding in a given place and time by repeated regularly eating and dietary habits. Polish migration to Greece contributed not only to change their place of residence, but also forced them to adapt to a new country. In the literature, foreign language is used for this purpose, the concept of acculturation, which can be distinguished in many aspects of life as well as on the diet. Acculturation related to a diet is called acculturation nutritional and can cause desirable or undesirable effects on nutrition. OBJECTIVE: To compare calorific intakes and core nutritional components in the daily diets of Poles and native Greeks, residing in Athens. Materials and methods. Three repeats of completing a 24-hour food questionnaire were performed for the study. Results were compared with known nutritional requirements and recommendations (according to weighted means). SUBJECTS: These were recruited at the turn of 2010/2011 in Athens and consisted of 66 persons aged 19-26, 31-50 and 51-65 years of whom 31 were Polish and 35 Greek. In the former, 18 (58%) were women and 13 (42%) men, whilst in the latter 19 were women (54%) and 16 men (46%). RESULTS: Daily dietary intakes of calories were 1832 kcal for the Poles but 1628 kcal for the Greeks. Significant differences were observed between the subject groups for daily dietary intakes of calories, total carbohydrate, fibre, saturated fatty acids (SFA) and poly-unsaturated fatty acids (PUFA). In women subjects, both Polish and Greek, these significant differences were seen in calorific and carbohydrate intakes, whereas for Polish and Greek men such differences were limited only to dietary fibre. CONCLUSIONS: The daily diets of Poles and Greek subjects living in Athens did not meet recommended standards of proper nourishment.

[Program for promoting social attachment among Poles in Australia in relation to their mental status]. / Program promocji wiezi spolecznych wsród polaków w Australii w odniesieniu do problemów psychicznych.

Among the Polish community in Sydney in 1989 there was a significantly higher percentage of men than women. Compared to the Australian population, there was also a high percentage of single people (especially men), a high rate of childlessness and a majority of incomplete families. The data on admission to psychiatric institutions in New South Wales indicate, that Polish-born persons (males) hospitalized with psychiatric disorders were 2.5 times more than the population of Australian-born. Sociologists pointed that because of lesser contacts with other members of their ethnic groups, people find themselves isolated. There were also limited family members or relatives who could provide support. From the South Western Sydney Area Health Service initiative a 2-year programme "Gazeta seniora". The strategic goal was to reduce number of isolated Polish-born older people through a number of regular initiatives: newspaper supplement, radio programmes, meeting groups, phone line. According to the information obtained from health and social services and from the respondents survey, letters and interviews, there was an increased access to medical services (15 percent), number of ethic meeting groups (40 percent). The programme has encouraged community leaders to provide personal contact and support for isolated people. After two years there were twice as many programme participants "satisfied with life" mainly because of "other peoples and the community's" involvement (from 7.0 to 21.4 percent). In the discussion part the authors stressed a holistic and long-term aspect of social and environmental support of any community based health promotion intervention related to psychic health improvement.
