The administrative management of skills on both qualitative and quantitative levels is one of the essential functions of a health system. To better implement policies of fight against High Blood Pressure (HBP) and other chronic diseases, it is important to establish strategies to retain health personnel. This loyalty requires favorable working conditions and consideration of the contribution-reward couple. Good working conditions are likely to reduce the phenomenon of medical nomadism;conversely, poor HR management can contribute to their exodus towards exotic “green pastures”, thus leading to an additional crisis in the Cameroonian health system. The fight against HBP is a complex, multifaceted and multifactorial reality that requires appropriate management model for all types of resources mainly HR. The main objective of this research is to show the impact of poor management of human resources in Cameroon health system on medical nomadism and the ineffectiveness of the fight against High Blood Pressure. Method: A cross-sectional descriptive survey among five hundred (500) health facilities in the center region of Cameroon has been conducted. A stratified probabilistic technique has been used, and the number of health facilities to be surveyed has been determined using the “sample size estimation table” of Depelteau. The physical questionnaires have been printed and then distributed to data collectors. After data collection, the latter were grouped during processing in Excel sheets. The Chi-square test was used for data with a qualitative value and that of Kolmogorov-Sminorf for data with a quantitative value to assess the normality and reliability of data. The Crochach’s Alpha reliability test allowed us to have a summary of the means and variances and then to search for intragroup correlations between variables. Descriptive analysis was possible with the XLSTAT 2016 software. Results: 43.60% of Health Facilities (HF) managers were unqualified. 82.20% of HF managers have staff in a situation of professional insecurity. They are mainly contractual (49.00), decision-making agents (24.40%), casual agents (08.80). The proportion of unstable personnel is average of 22.00% and very unstable, 12.00%.展开更多

The subsistence strategy is arguably an effective proxy for the integration of various groups of people(e.g. farmers and nomads). In this paper, we have reported new stable isotope data from the Huangwan tombs dated to the Han dynasty in middle Gansu, which was the key juncture between the Han and Xiongnu empire, in order to fill the gap and further understand the substance strategies employed by the local people. According to the results of plant remains and stable isotopic data, millet farming, the typical agricultural activities for the Han Chinese in the Central Plains, was also the primary lifestyle for the Huangwan people in the mid Gansu. More importantly, this shows fundamentally remarkable difference from the agricultural practices in the Bronze Age Gansu Corridor, which were based on a variety of crops, including wheat, barley and millet. This major shift in the subsistence production at Huangwan can be correlated to a wider historical background in which the Han empire showed increasing political and military presence in the Gansu Corridor, indicating that local indigenous nomads followed the lifestyle of Han Chinese(e.g., millet farming), and/or the Han immigrates maintained millet farming.展开更多

All of these areas are close to become conflict zones. However, no data about the Tubu's health and sanitary status are currently available, which would be of major concern if humanitarian interventions would become required.Methods: In 1970, the "Mission Anthropologique Belge au Niger"(MABN) investigated a Tubu tribe named Broaya that lived at Seguedine and Djado on the northeastern rim of the Tenere desert. One hundred fifty-one adult volunteers answered an oral questionnaire and underwent a medical examination, followed by the collection of blood thin films and samples of urine and stool. The environmental fauna of medical importance was also studied.Results: Albeit 43 year-old, these results have not been previously published. The estimated age of death for fathers was approximately 56 years, and that for mothers was 60 years. On average, each married woman had had 4.7 children. The overall perinatal mortality rate was 232 ‰, the overall infant mortality rate was 153 ‰, and the overall child mortality rate was 99 ‰. The mean height was 164.1 cm and 157.4 cm, the mean weight was 50.1 kg and 47.9kg, and the mean blood pressure was 131/78 mm Hg and 127/75 mm Hg for males and females, respectively. The physical examination found 6 cases of blindness(4.0%). Five subjects presented with an elevated blood pressure(3.3%), and 5(3.3%) displayed an abnormal thoracic auscultation evocative of tuberculosis or of an acute lung infection. The abdominal examination and renal palpation found 5 large masses(3.3%), and 2 subjects had a palpable enlarged spleen(1.3%). The blood thin films were fixed in methanol and subsequently examined in Toulouse. The search for blood parasites was negative. The urine samples were centrifuged and then microscopically examined in the field. No blood-fluke eggs were found. The stool samples were mixed with a preservative MIF solution and then stored to be examined later in Toulouse. Three subjects(2%) passed E. histolytica/E. dispar cysts in stools, 16(10.6%) were parasitized with Giardia sp. and 4(2.65%) were parasitized with Hymelepis nana. Two specimens of scorpions captured in the camp were subsequently identified as belonging to the harmful genus Androctonus or Leiurus. An investigation into the freshwater fauna was conducted in the marshy ponds surrounding the ghost city of Djado, and no intermediate snail hosts for schistosomiasis haematobium were found. Numerous nymphs of Ceratopogonidae, which are possible vectors for arboviruses of veterinarian importance, were collected, as were larvae and nymphs from two anopheline species, Anopheles hispaniola and An. multicolor, which are not efficient vectors for malaria.Conclusions: Infection-related blindness and trachoma, along with acute pulmonary infections and probably tuberculosis were the major health burden in this tribe. The harsh dry and hot climate may explain the low prevalence of soil-transmitted protozoan diseases or helminthiases.展开更多

The disease is common in most developing countries, the human mortality rate is about 2%, and the disease causes severe rheumatism, infertility in males, spontaneous abortion and also results in wastage of resources through prolonged treatment. Brucella organisms are also potential biological weapon which could be cheaper to produce but more devastating than chemical weapons. About 5 mililitres of blood was drawn from 228 subjects using sterile vacutainers and analyzed by using standard tube agglutination tests: (SAT3 160) and ELISA (IgG, IgM) kits specific for Brucella abortus and Brucella melitensis antibodies. Semi structured questionnaire was administered to collect data. In the study, overall sero prevalence was 70 (30.8%). More male participated in the study with a frequency of 24.6% of whom 7.92% falls within the age group of 20 to 30, followed by 31 - 35 years with 5.72% and 3.52% within 36 - 45 years. Least affected were those in the age groups above 46 years (2.20%). Approximately, 21.54% of the subjects had formal education either at Quranic, primary and secondary or tertiary level. Majority acquired Quranic education (9.68%), 7.48% primary and 0.88% had tertiary training. A total of 21 (9.24%) never acquired any form of education. Headache, muscle aches, malaise, chills and fatigue were the most common clinical signs and symptoms experienced by about 30% among the participants. In the distribution of Brucella antibodies, ELISA diagnostic kits showed high sensitivity with the prevalence rate of 18.04% (n = 41) followed by SAT 12.76% (n = 29). The sensitivity and specificity of RDPT kits were 37 % and 69%, with a positive and negative predictive value of 18% and 86% respectively. Unprocessed milk from the market and consumption of unboiled milk were associated with brucellosis. Therefore, patients with brucellosis should be treated to prevent the devastating effect of the disease and the accompanying sequelae, public health education programs should explain modes of transmission and Brucella febrile diagnostic kit should be used at the health facilities.展开更多

The above conditions contribute to the types and nomadic features of traditional Mongolian furniture. Most traditional Mongolian furniture has a box-like structure, and the nomadic features are reflected in the following aspects: made of local materials; small size for the application in Mongolian yurt; demountable and foldable for the convenience of transportation,because Mongolians have to move to different grasslands for grazing; the furniture parts is bulky for frequent transportation; and colored drawing and carved furniture enrich the life color.展开更多
