The objective of this study was to evaluate the prevalence of digestive parasitosis in children of this population in the Hauts-Bassins region. Material and methods: This was a prospective cross-sectional study from November to December 2020, in which stool samples were collected from internally displaced children from the Sinfra reception site in Banzon and from Poya in Karangasso Vigué. The stool samples were stored at room temperature, protected from dust and insects, in a cooler and then sent to the laboratory of the CHUSS in Bobo-Dioulasso where the parasitological analyses were performed. Results: The mean age was 5.8 ± 2.4 years. The most represented age group was 5 to 10 years (75.31%). The sex ratio is 1.61. The overall prevalence of intestinal parasite infection was 53.09%. The prevalence was statistically higher among those who consumed well water than those consuming tap water (p = 0.01). Monoparasitism by protozoa and helminths represented 74.42% and 6.68% respectively. The polyparasitism rate was 9.31%. The species identified in monoparasite patients were protozoa with Entamoeba coli (37.21%), Giardia lamblia (25.58%), Endolimax nanus (6.98%) and Entamoeba histolytica/dispar (4.65%). Biparasitism was identified with combinations, such as E. coli + E. histolytica/dispar (11.63%). Conclusion: There is a high prevalence of digestive parasitosis among IDPs in the Sinfra and Poya reception site. Educational sessions on hand washing before meals, use of drinking water, etc. should emphasize preventive measures in these IDP camps.展开更多

Remarkably, the initial DTS, an example of a mixed state, still remains mixed and thermal. At long times, they finally decay to a highly classical thermal field only related to the laser parameters κ and g. The normal ordering product of density operator of the DTS in the laser channel leads to obtaining the analytical time-evolution expressions of the photon number, Wigner function, and von Neumann entropy. Also, some interesting results are presented via numerically investigating these explicit time-dependent expressions.展开更多

METHODS Following an agreed interdepartmental protocol, fractures of the radius and ulna(moderately to severely displaced) in children between the age of 2 and 16 years old, presenting within a specified 4 mo period, were manipulated in our paediatric emergency department. Verbal and written consent was obtained prior to procedural sedation to ensure parents were informed and satisfied to have ketamine. A single attempt at manipulation was performed. Pre and postmanipulation radiographs were requested and assessed to ensure adequacy of reduction. Parental satisfaction surveys were collected after the procedure to assess the perceived quality of treatment. After closed reduction and cast immobilisation, patients were then followed-up in the paediatric outpatient fracture clinic and functional outcomes measured prospectively. A cost analysis compared to more formal manipulation under a general anaesthetic was also undertaken.RESULTS During the 4 mo period of study, 10 closed, moderate to severely displaced fractures were identified and treated in the paediatric emergency department using our ketamine sedation protocol. These included fractures of the growth plate(3), fractures of both radius and ulna(6) and a single isolated proximal radius fracture. The mean time from administration of ketamine until completion of the moulded plaster was 20 min. The mean time interval from sedation to full recovery was 74 min. We had no cases of unacceptable fracture reduction and no patients required any further manipulation, either in fracture clinic or under a more formal general anaesthetic. There were no serious adverse events in relation to the use of ketamine. Parents, patients and clinicians reported extremely favourable outcomes using this technique. Furthermore, compared to using a manipulation under general anaesthesia, each case performed under ketamine sedation was associated with a saving of ￡1470, the overall study saving being ￡14700. CONCLUSION Ketamine procedural sedation in the paediatric population is a safe and cost effective method for the treatment of displaced fractures of the radius and ulna, with high parent satisfaction rates.展开更多

Indeed, just a simple comparison has been performed between the standard coherent state and nonlinear coherent state for the formation of NDNSs. In the present paper, after expressing enough physical motivation of our procedure, four distinct classes of NDNSs are presented by applying algebraic and group treatments. To achieve this purpose, by considering the DNSs and recalling the nonlinear coherent states formalism, the NDNSs are logically defined through an algebraic consideration. In addition, by using a particular class of Gilmore-Perelomov-type of SU（1,1） and a class of SU（2） coherent states, the NDNSs are introduced via group-theoretical approach. Then, in order to examine the nonclassical behavior of these states, sub-Poissonian statistics by evaluating Mandel parameter and Wigner quasi-probability distribution function associated with the obtained NDNSs are discussed, in detail.展开更多

Several kinds of displaced orbits for geocentric and martian cases were discussed. First, the relative motion was linearized around the displaced orbits. Then, two seminatural control laws were investigated for each kind of orbit and the stable regions were obtained for each case. One of the two control laws is the passive control law that is very attractive for engineering practice. However, the two control laws are not very suitable for the Martian mission. Another special semi-natural control law is designed based on the requirement of the Martian mission. The results show that large stable regions exist for the control law.展开更多

We derive new generating function formulas and binomial formula involving twovariable Hermite polynomials to reach this result. The photon number average in this new optical field is m＋｜α｜^2e^-2κt,which indicates that controlling the photon number can be realized by adjusting the value of m or ｜α｜2 or κ. The time evolution law of displaced Fock state in a thermo reservoir is thus revealed.展开更多

Three-dimensional co...Coupled trajectory and attitude stability of displaced solar orbits is studied by using sailcraft with a kind of two-folding construction with two unequal rectangular plates forming a right angle. Three-dimensional coupled trajectory and attitude equations are developed for the coupled dynamical system, and the results show that all three types of displaced solar orbits widely referenced can be achieved through selecting an appropriate size of the two-folding sail. An anal- ysis of the corresponding linear stability of the trajectory and attitude coupled system is carried out, and both trajectory and attitude linearly stable orbits are found to exist in a small range of parameters, whose non-linear stability is then examined via numerical simulations. Finally, passively stable orbits are found to have weak stability, and such passive means of station-keeping are attractive and useful in practice because of its simplicity.展开更多

METHODS： Literature search was performed of PubMed and Cochrane Library by two independent authors to identify randomized controlled trials （RCTs） comparing operative vs nonoperative treatment of DIACF from inception to December 31st, 2013. RCT quality was evaluated by the modified Jadad scale. Dichotomous variables were pooled using risk ratios by review manager 5.3 software. Fixed-effects or random-effects models were adopted with P 〉 0.05 or P ≤ 0.05 for heterogeneity tests, respectively.RESULTS： Eight RCTs comprising 767 cases met inclusion criteria. Results revealed that more surgically treated patients could resume pre-injury job （P = 0.006）. No statistical differences were found between the two groups in residual pain （P = 0.33）, shoe fitting problems （P = 0.07）, limited walking distance （P = 0.56） or secondary late arthrodesis （P = 0.38）. However, operative treatment was associated with a higher complication rate （P = 0.003）. Subgroup analyses of specific complications revealed that except for a higher risk of superficial wound problems （P 〈 0.0001） in operative group, the two groups had similar complication rate in deep wound infection （ P = 0.34）,CONCLUSION： Current evidence demonstrates that compared with operative treatment, conservative treatment of DIACF lead to similar clinical outcomes regarding residual pain, shoe fitting, walking distance and secondary subtalar arthrodesis but a significantly lower complication rate.展开更多

We investigated accessibility to and availability of health care services for the internally displaced persons in Kitgum and Pader districts, northern Uganda. Methods: This was a cross-sectional study conducted in Kitgum and Pader districts, northern Uganda. We interviewed a total of 1383 respondents comprising 968 (70%) adults and 415 (30%) adolescents;60% were females and 40% males, randomly selected from 35 of 67 (52.2%) internally displaced persons (IDP) camps. We held 27 key informant interviews and 52 focus group discussions. Data were entered in EPI data version 3.02 and analysed using SPSS version 12.00 statistical packages. Findings: Two thirds of the respondents 67.5% lived within 5 km distance of a health facility. The majority 62.9% of respondents mentioned that health related information was readily provided. 43.5% of health providers were always available in a health facility. A quarter 25.1% of health facilities always had drugs available, while 56.9% of the drugs prescribed were always available. Two thirds of the respondents 65.9% were satisfied with the health care services provided. The main reasons for the choice of a health facility were proximity 29.6%, provision of free treatment 24.7% and availability of drugs 17.2%. Main barriers to health care access were due to the lack of financial resources, trained personnel, and inadequate drugs and supplies in the health facilities. Conclusions and Recommendations: The majority of IDPs lived in close proximity to health facilities and obtained health care services from public health facilities. Access to health care was determined mainly by proximity and availability of free services and drugs. Although geographic accessibility to health services was high, lack of finances, information and decision power hindered access to health care services.展开更多

This infection is contagious and mostly acquired during childhood through the fecal-oral and oral-oral route. A total of 1560 blood specimens were aseptically collected from Internally Displaced Persons comprising female and male from the warring communities of Bakassi Peninsular and Etim Ekpo Local Government Area in South Southern, Nigeria. The specimens were screened for H. pylori using Elisa kits following standard serological techniques. The overall prevalence rate was 464 (29.7%). There was significant difference (p H. pylori infection;its distribution varied between age group, educational status, habits or behaviors of the subjects with children within 5 to 14 years having the highest rate of 274 (17.6%), followed by 78 (4.99%) from adults (51 years and above) and 17 (1.08%) from active age range of 36 - 45 years old. Subjects with primary and quranic level of education showed a total of 274 (17.56%) positive cases to H. pylori. Analysis of sex-specific distribution revealed that females had the highest prevalence of 312 (20%). The helicobacter infection shows a significant difference at (p H. pylori infection. Crowding in camps and increasing household contact have been considered as risk factors of H. pylori infection. Adequate infrastructural provision and availability of portable water with good hygienic environment will drastically reduce the high rate spread of H. pylori bacterium in the IDPs communities in Nigeria.展开更多

This article aims at critically analyzing the tuberculosis risks among displaced people especially as there is an increase in the number of migrants globally and proliferation of man-made and natural disasters. Research conducted among displaced persons and most of the studies concluded that active surveillance and proper case follow-up are the best ways to ensure adequate tuberculosis case management. In conclusion, the application of diverse methods in tackling tuberculosis risks should be especially through a culturally, acceptable precise and feasible plans without compromising international standards.展开更多

文摘The paper investigates the relative motion around the planetary displaced orbit. Several kinds of displaced orbits for geocentric and martian cases were discussed. First, the relative motion was linearized around the displaced orbits. Then, two seminatural control laws were investigated for each kind of orbit and the stable regions were obtained for each case. One of the two control laws is the passive control law that is very attractive for engineering practice. However, the two control laws are not very suitable for the Martian mission. Another special semi-natural control law is designed based on the requirement of the Martian mission. The results show that large stable regions exist for the control law.

文摘We explore how a displaced chaotic light (DCL) behaves in an amplitude dissipation channel, and what is its time evolution formula of photon number distribution. With the use of the method of integration within ordered product product of operator (IWOP) and the new binomial theorem involving two-variable Hermite polynomials we obtain the evolution law of DCL in the channel.

文摘We propose a new optical field and show that such an optical field can be generated as an output of a displaced Fock state in an amplitude dissipative channel. We derive new generating function formulas and binomial formula involving twovariable Hermite polynomials to reach this result. The photon number average in this new optical field is m＋｜α｜^2e^-2κt,which indicates that controlling the photon number can be realized by adjusting the value of m or ｜α｜2 or κ. The time evolution law of displaced Fock state in a thermo reservoir is thus revealed.

文摘Coupled trajectory and attitude stability of displaced solar orbits is studied by using sailcraft with a kind of two-folding construction with two unequal rectangular plates forming a right angle. Three-dimensional coupled trajectory and attitude equations are developed for the coupled dynamical system, and the results show that all three types of displaced solar orbits widely referenced can be achieved through selecting an appropriate size of the two-folding sail. An anal- ysis of the corresponding linear stability of the trajectory and attitude coupled system is carried out, and both trajectory and attitude linearly stable orbits are found to exist in a small range of parameters, whose non-linear stability is then examined via numerical simulations. Finally, passively stable orbits are found to have weak stability, and such passive means of station-keeping are attractive and useful in practice because of its simplicity.
文摘AIM:To estimate post-war burdens of trachomatous trichiasis(TT)and multi-level risk factors among displaced population in Raya Kobo districts,implication for urgent action.METHODS:A community-based cross-sectional study was conducted among 603 participants from randomly selected 14 displaced slums in the Raya Kobo district.The data was collected from February 16th to March 30th,2023.Study participants were selected using the multistage sampling technique.A structured questionnaire and ophthalmic loupe with×2.5 magnificence were used to collect from participants.Multi-level binary logistic regression was used to determine associated factors with TT infection.Adjusted odds ratio(AOR)with 95%confidence interval(CI)were claimed for the strength of association at P<0.05.RESULTS:We recruited 602(99.9%)participants for the final analysis.From the total,126(20.9%)and 98(16.3%,95%CI:13.5%-19.4%)participants were diagnosed with active trachoma&TT infection,respectively.Being age≥45y(AOR=7.9,95%CI:2.4-25.3),having multiple eye infections(AOR=2.73,95%CI:1.47-5.29),poor wealth index(AOR=9.2;95%CI:2.7-23.7)and twice face washing per day(AOR=0.082,95%CI:0.03-0.21)has identified as individual as factors for TT infection.Whereas,distance between clean water source≥10 km(AOR=6.5,95%CI:3.9-31.3),and latrine availability(AOR=0.35,95%CI:0.21-0.58)were the two community-level factors associated with TT infections.CONCLUSION:The high prevalence of TT infection post-war throughout the study districts indicates a need for urgent clinical intervention in addition to rapid scaling up surgery,antibiotics,facial cleanliness,and environmental improvement(SAFE)strategies,strategy for high-risk population.Age≥45y,distance from the clean water source,poor wealth indexes,and eye infection are identified to be risk factors for TT infection.Furthermore,community-level preventative factors for TT infection are found as latrine availability and face washing practice.
文摘AIM： To investigate clinical efficacy of displaced intra-articular calcaneal fracture （DIACF） following operation and nonoperation. METHODS： Literature search was performed of PubMed and Cochrane Library by two independent authors to identify randomized controlled trials （RCTs） comparing operative vs nonoperative treatment of DIACF from inception to December 31st, 2013. RCT quality was evaluated by the modified Jadad scale. Dichotomous variables were pooled using risk ratios by review manager 5.3 software. Fixed-effects or random-effects models were adopted with P 〉 0.05 or P ≤ 0.05 for heterogeneity tests, respectively.RESULTS： Eight RCTs comprising 767 cases met inclusion criteria. Results revealed that more surgically treated patients could resume pre-injury job （P = 0.006）. No statistical differences were found between the two groups in residual pain （P = 0.33）, shoe fitting problems （P = 0.07）, limited walking distance （P = 0.56） or secondary late arthrodesis （P = 0.38）. However, operative treatment was associated with a higher complication rate （P = 0.003）. Subgroup analyses of specific complications revealed that except for a higher risk of superficial wound problems （P 〈 0.0001） in operative group, the two groups had similar complication rate in deep wound infection （ P = 0.34）,CONCLUSION： Current evidence demonstrates that compared with operative treatment, conservative treatment of DIACF lead to similar clinical outcomes regarding residual pain, shoe fitting, walking distance and secondary subtalar arthrodesis but a significantly lower complication rate.
文摘Introduction: During 1986-2009, an estimated 1.6 million persons were internally displaced from northern and eastern regions of Uganda due to civil war. We investigated accessibility to and availability of health care services for the internally displaced persons in Kitgum and Pader districts, northern Uganda. Methods: This was a cross-sectional study conducted in Kitgum and Pader districts, northern Uganda. We interviewed a total of 1383 respondents comprising 968 (70%) adults and 415 (30%) adolescents;60% were females and 40% males, randomly selected from 35 of 67 (52.2%) internally displaced persons (IDP) camps. We held 27 key informant interviews and 52 focus group discussions. Data were entered in EPI data version 3.02 and analysed using SPSS version 12.00 statistical packages. Findings: Two thirds of the respondents 67.5% lived within 5 km distance of a health facility. The majority 62.9% of respondents mentioned that health related information was readily provided. 43.5% of health providers were always available in a health facility. A quarter 25.1% of health facilities always had drugs available, while 56.9% of the drugs prescribed were always available. Two thirds of the respondents 65.9% were satisfied with the health care services provided. The main reasons for the choice of a health facility were proximity 29.6%, provision of free treatment 24.7% and availability of drugs 17.2%. Main barriers to health care access were due to the lack of financial resources, trained personnel, and inadequate drugs and supplies in the health facilities. Conclusions and Recommendations: The majority of IDPs lived in close proximity to health facilities and obtained health care services from public health facilities. Access to health care was determined mainly by proximity and availability of free services and drugs. Although geographic accessibility to health services was high, lack of finances, information and decision power hindered access to health care services.

文摘It is established in the psychological literature that pre-displacement stressors,PTSD symptoms,and psycholo-gical distress are associated among internally displaced persons.However,existing studies have not demonstrated the mechanism underlying these associations.This study compared two explanatory models;one with PTSD symptoms severity explaining the indirect association between pre-displacement stressors and psychological dis-tress,and the other with psychological distress explaining the indirect relationship between pre-displacement stressors and PTSD symptoms severity.In a cross-sectional design,631 women(Mean age=31.18±8.59)were conveniently and purposely selected from the displaced women harboured in two camps in Borno State,Nigeria,due to the Boko-Haram insurgency.Data were collected utilizing structured questionnaires and subjected to path analyses.Results demonstrated that PTSD symptoms severity and psychological distress indirectly explained their respective and independent association with pre-displacement stressors.However,PTSD symptoms had a statis-tically larger standardized indirect effect size,greater indirect effect percentage,and bigger kappa-squared(k2)effect size than psychological distress.PTSD symptoms and psychological distress may have a reciprocal influence on each other from pre-displacement stressors.However,PTSD symptoms can better explain the association between pre-displacement stressors and psychological distress than the other way around.These outcomes have important implications for the psychological treatment of displaced persons.
文摘Helicobacter pylori (H. pylori), is an important global infection with a worldwide prevalence of about 40 percent. This infection is contagious and mostly acquired during childhood through the fecal-oral and oral-oral route. A total of 1560 blood specimens were aseptically collected from Internally Displaced Persons comprising female and male from the warring communities of Bakassi Peninsular and Etim Ekpo Local Government Area in South Southern, Nigeria. The specimens were screened for H. pylori using Elisa kits following standard serological techniques. The overall prevalence rate was 464 (29.7%). There was significant difference (p H. pylori infection;its distribution varied between age group, educational status, habits or behaviors of the subjects with children within 5 to 14 years having the highest rate of 274 (17.6%), followed by 78 (4.99%) from adults (51 years and above) and 17 (1.08%) from active age range of 36 - 45 years old. Subjects with primary and quranic level of education showed a total of 274 (17.56%) positive cases to H. pylori. Analysis of sex-specific distribution revealed that females had the highest prevalence of 312 (20%). The helicobacter infection shows a significant difference at (p H. pylori infection. Crowding in camps and increasing household contact have been considered as risk factors of H. pylori infection. Adequate infrastructural provision and availability of portable water with good hygienic environment will drastically reduce the high rate spread of H. pylori bacterium in the IDPs communities in Nigeria.

文摘We show that chaotic state can be produced as an output of vacuum state evolving in diffusion channel,while displaced chaotic state is output of a coherent state evolving in diffusion channel.We also introduce the thermo vaccum state for the displaced chaotic state and evaluate the average photon number.The displaced chaotic state may be used exhibiting quantum controlling.
文摘The UNHCR 2017 report stated that about 44,400 people are displaced from their homes daily and about 68.5 million people are currently displaced globally. This article aims at critically analyzing the tuberculosis risks among displaced people especially as there is an increase in the number of migrants globally and proliferation of man-made and natural disasters. Research conducted among displaced persons and most of the studies concluded that active surveillance and proper case follow-up are the best ways to ensure adequate tuberculosis case management. In conclusion, the application of diverse methods in tackling tuberculosis risks should be especially through a culturally, acceptable precise and feasible plans without compromising international standards.
