In Cameroon, the maternal mortality rate remains high, and the scarcity of data on abortions leads to a lack of solid evidence to advocate on the extent of the abortions related complications. Our objective was to evaluate the unsafe abortions related complications, and to assess the difficulties of accessing safe abortions in our setting. Methods: We carried out a meta-analytic and systematic review in the biomedical databases MEDLINE (Pubmed), Google Scholar and African Journal Online concerning unsafe abortions and/or difficulties in accessing safe abortions in Cameroon. The keywords used for the search are seen in table I. Selection of studies was simultaneously done by two authors. Data were extracted through a form designed on Google Form. We used a random-effect model for proportion estimation, and The I<sup>2</sup> and Q statistics to assess the extent of heterogeneity. Results: A total of 430 studies were identified, from which 28 were included and analysed. About 5% (95% CI: 3 - 7) of unsafe abortions leads to death. The contribution of unsafe abortions in maternal deaths was 23% (95% CI: 20 - 27). The rate of severe bleeding and/or anemia were 40% (95% CI: 18 - 63) and the rate of infection was 17% (95% CI: 7 - 28), dominated by pelvic infections, pelviperitonitis, severe sepsis, and septic shock. Case reports described uterine perforations, uterine rupture during the following pregnancy. Abortion was performed in the practitioner’s or patient’s home in 41.4% of cases, in a health center in 35.1% of cases, in a private clinic in 21.2% of cases, drugs selling places and in traditional healer clinics. The restriction of abortion laws, the stigma surrounding abortion and its consequences at any level of the society, lead to the underreporting of unsafe abortions and a deep reluctance to advocate for safe abortion services. Conclusion: The strengthening of awareness campaigns for provider behavior change communication, family planning, the de-stigmatization of abortions, the training of health personnel in post-abortion care, a multidisciplinary and multicentric action would contribute to the reduction in morbidity and mortality due to abortions.展开更多

The precise prevalence of G6PD is unknown in Burkina Faso. The objective of the study was to describe the difficulties to diagnose this disease at the Souro Sanou University hospital (CHUSS) in Bobo-Dioulasso. It involved five patients comprising one child with homozygous SS sickle cell disease, one adolescent screened following a family investigation, and three adults including a man and two women. Blood smear stained with May Grunwald Giemsa was performed to look for specific signs of G6PD-deficient red blood cell and brilliant cresyl Blue for Heinz Bodies. A microscope Olympus BX53 equipped with a Camera (XC10) and connected to a computer was used to read blood smears and capture images. Genes sequencing by Sanger method were performed in a specialized laboratory in molecular genetics. For each analysis, the protocol and instructions of the equipment and reagent manufacturer were applied. Of the five patients, three had anemia and only one had hyperreticulocytosis. Two patients had biological signs of hemolysis and one patient had an elevated CRP. Blood smear stained with MGG and cresyl blue showed specific signs of G6PD-deficient red blood cells and Heinz bodies in all patients. Biochemical analysis and molecular typing confirmed G6PD deficiency. The presence of G6PD-deficient red blood cells in the blood smear guides the diagnosis of G6PD deficiency. The diagnosis is biochemical and is based on the combined measurement of G6PD plus pyruvate kinase and/or hexokinase.展开更多

Ten nurses who worked at emergency and critical care centers in Japan were directly involved in nursing patients were selected by purposive sampling and underwent semi-structured interviews regarding the difficulties they experienced in trauma nursing. The nurses were specialists in critical care nursing or were certified emergency nurses. The interview responses were analyzed by the qualitative descriptive method. The following six categories of difficulties associated with the direct care of trauma patients and their family members encountered in trauma nursing practice were identified: [Initial handling of highly urgent trauma patients], [Understanding and observing the condition of patients who are in the treatment stage], [Judging when to transition to end-stage care for patients difficult to save], [Mitigating suffering and expanding safe activities of daily living for trauma patients], [Transitional care with a long-term perspective for trauma patients], and [Relationships with the family members of patients who died]. Three categories of difficulties related to the role of the expert nurse in trauma nursing practice were identified: [Person-to-person coordination and cooperation for a trauma patient], [Playing an educational role for the nursing staff], and [Pursuing expertise in trauma nursing and gaining empirical knowledge]. The findings suggested a need to establish systems for training and consultative support and opportunities to create meaning by reflecting on fulfillment and nursing practice.展开更多

This was a cross sectional study of Lusaka school children (n = 420) aged 11-15 years using the self-report SDQ-Y and a demographic questionnaire. It was found that compared to a UK normative sample, Zambian adolescents were almost twice as likely to have total difficulties scores in the abnormal range (O.R. 1.9). It was found that there was a significant difference in the total SDQ scores (Z = -2.67, P = 0.008) with children reporting health problems having significantly higher scores. Children reporting health problems also had significantly more emotional problems (Z = -2.78, P = 0.005). There was a trend for children with health problems to score higher on the hyperactivity scale (Z = -1.9 P = 0.053). The internal consistency of SDQ subscales ranged from low to moderate. It can be concluded that SDQ is a useful instrument for use with Zambian adolescents, in particular, the total difficulties score and the emotional difficulties score performed well in this sample and could potentially be used to screen for mental health problems or to examine the impact of interventions.展开更多

Their repercussions are functional, aesthetic and psychological. The initial emergency or secondary management of facial damage is difficult. The objective is to report, through the clinical observation of three patients, the results of the management of complex facial dislocations in a context of limited technical resources. Patients and methods: Three complex post-traumatic facial dislocations were managed between May 2006 and June 2017. Results: Primary treatment and secondary repair were established on a case-by-case basis. Local autoplasty was the indication of choice. Multidisciplinary management resulted in satisfactory functional and cosmetic outcomes. Two of the patients were lost to follow-up before the end of treatment. Discussion: The complete management of facial dislocations remains difficult and complex, in an extreme exercise situation. In an emergency, the priority is to save the life of the injured person. Several factors are involved in the therapeutic decision: the choice of the maxillofacial reconstruction technique, the availability of the technical platform, the financial capacity and the psychological state of the patient and his entourage. Sequential and multidisciplinary treatment gives satisfactory results in terms of morphology, function and aesthetics, despite the limited technical resources available. Psychological support is an essential complement for successful socio-professional and family reintegration.展开更多

Aims/Objectives: To evaluate the causes of male sexual or coital difficulties among couples attending the infertility clinic at BSUTH, Makurdi over a 2 year period. Methodology: This was a cross-sectional study involving all males attending the infertility clinic at Benue State University Teaching Hospital (BSUTH) who consent to participate in the study. A pretested structured questionnaire was administered and analyzed with statistical package for social sciences (version 23.0) and the results were presented in simple proportions. Results: There were several factors responsible for male coital difficulties. The most common was male erectile dysfunction 33 (32.4%), vaginismus 11 (10.8%), penile pain 14 (13.7%), poor response from the female partner 8 (7.8%) and severe dyspareunia 18 (17.1%). Conclusion: Coital difficulties resulting to low frequency of sexual exposure constitutes a major cause of infertility among males attending the infertility clinic at BSUTH, Makurdi. Therefore efforts should be made to evaluate these factors while assessing infertility couples in order to mitigate the effect.展开更多

The objective of present study was to investigate the difference on task performance, brain activation and subjective assessment in relation to the difficulty levels of the tasks. Subjects were asked to buy specific 2 items in Task 1, 4 items in Task 2, and 6 items in Task 3 at a virtual mall. The tasks and questionnaires were conducted on 10 convalescent brain-damaged patients and 6 healthy young adults. Hemodynamic changes in the prefrontal cortex (PFC) during activation due to the tasks were examined using functional near-infrared spectroscopy. As the result, the mean total time was significantly longer for the patients than for healthy subjects. PFC showed a greater response for related Task 2 than Task 1 in shopping and moving phase in patient group. The patients evaluated Tasks 1 and 2 are more difficult and bring more psychological load than healthy adults subjectively. That is, although the healthy adults did not show large difference in their task performances as well as PFC responses, they can evaluate the differences between three task levels, subjectively, while which could not be for the patients means that patients could not distinguish the difference of the tasks, subjectively. The results suggest that 4-item shopping task might be enough difficulty level that causes brain activation for the brain-damaged patients.展开更多

At present,there are difficulties of putting a case on file,collecting evidence,judicial identification,and presumption of causal relationship in investigation of environmental pollution cases. In accordance with current situations,it came up following recommendations:(i) widely collecting case clues to solve the difficulty of putting a case on file;(ii) improving the ability of collecting evidence and standardizing the evidence collection,to solve the difficulty of evidence collection.(iii) including the environmental pollution judicial identification system,and unifying the identification standards,to solve the difficulty in identification. It is recommended to use the epidemiological causal relationship theory combined with enough high-quality evidences to solve the difficulty in presumption of causal relationship.展开更多

The aim of this study was to assess reliability and validity of the Greek version of the SDQ. A representative Greek sample of 1194 adolescents (aged 11 to 17 years) and their parents completed the SDQ along with other measures. Internal consistency reliability was determined by calculation of the Cronbach α coefficient. Varimax Orthogonal Transformation was conducted to test the factor structure of the questionnaire. Validity was further examined by investigating the correlation of the SDQ with the KIDSCREEN questionnaire and its association with demographic factors. The inter-rater agreement between parent and self-reports was analyzed with Pearson’s correlation coefficient. Intra-class correlation coefficients (ICCs) were computed to determine test-retest stability. For both parent and the self-report SDQ versions, most items loaded onto their predicted factors in consistency with the originally proposed five-factor structure. Internal consistency reliability was acceptable with a Cronbach α above 0.70 for all SDQ scales except for conduct and peer problems. Inter-rater correlations ranged from 0.33 to 0.45. Test-retest stability was good (ICCs > 0.60). Correlation coefficients between the SDQ and KIDSCREEN questionnaire were significant. Small effect sizes (d > 0.5) of the socioeconomic status were found for all of the SDQ scale mean scores. In conclusion, the SDQ was found to have satisfying psychometric properties and could be suitable for assessing emotional and behavioural problems in Greek adolescents.展开更多

Vigorously developing irrigation and water conservancy can promote high yield and stable yield of grain, effectively increase farmers' income, alleviate the impact of drought on agricultural production, be conducive to the adjustment of agricultural production structure, and promote county economic development. The difficulties of developing irrigation and water conservancy in new era are analyzed as follows: the subject of liabilities defaults seriously; it lacks effective input security system; the quality of project degenerates badly; the agricultural technological development is slow. Corresponding policy suggestions are put forward as follows: make the input subject of irrigation and water conservancy clear; form stable investment channels; strengthen the organizing and guiding functions of grass-roots government; reinforce the coordination and management of capital; strengthen the promotion of agricultural technology; quicken the pace of reform of irrigation and water conservancy.展开更多

The diagnosis mainly based on bacteriological and immunological evidence of mother-child couple is not always easy, as it is shown in our three clinical cases. Those three clinical observations demonstrate the difficulties encountered in the diagnosis of congenital syphilis in our country where only the TPHA (Treponema Pallidum Haemaglutination Assay) and VDRL (Venereal Disease Research Laboratory) tests are the only ones to be routinely carried out. Actually, these tests can be negative at the earliest stage of the syphilis or in case of zonal phenomenon. In addition, maternal antibodies could be found in child blood, even if the baby is in good health. At last, the child could have been contaminated belatedly while tests were negative at the third month of pregnancy. Congenital syphilis still exists in our developing countries and, in order to better manage this pathology, a proposition of an efficient algorithm is submitted.展开更多

It is one of the causes of maternal mortality in the world and particularly in developing countries. Despite the progress made, maternal mortality remains high in Cameroon. The scarcity and disparity of data on abortions lead to a lack of strong evidence to advocate to decision-makers on the extent of the problems associated with abortions in Cameroon. Our objective is to estimate the rates of mortalities and complications related to unsafe abortions, as well as the difficulties of accessing safe abortions in Cameroon. We will carry out a systematic and meta-analytical review in the biomedical databases MEDLINE (Pubmed), Google Scholar and African Journal Online (AJOL) concerning unsafe abortions and/or difficulties in accessing safe abortions in Cameroon, without date or language restriction. Gray literature will be also consulted. Two authors will simultaneously select the studies and data extraction will be done using a Google Form. Proportions will be estimated on a random-effect model. The I<sup>2</sup> and Q statistics will be used to assess the extent of heterogeneity across the studies. The outcome of both the quantitative and qualitative parts of the study will be commented. Death and morbidity due to abortions can be prevented. A concerted multidisciplinary and multicentric action would be essential.展开更多

文摘Estimated from family studies,the heritability of hypertension ranges from 31%to 68%.Linkage studies and candidate gene association studies were once widely used to investigate the genetic mechanisms of hypertension.However,results from these studies could only explain 1%-2%heritability.With the technological advances and subsequently the accomplishment of the Human Genome Project,genome-wide association studies(GWA studies)have been applied to find genome-wide significant signals for many common diseases.Current GWA studies of hypertension have identified dozens of hypertension or blood pressure associated variants.However,different GWA study identified different variants and the results could hardly be replicated in other studies.Therefore,a debate took place on whether GWA studies will unlock the genetic basis of hypertension and whether we shall continue throwing millions of dollars on GWA studies.This review gives a short introduction to the history of genetic study on hypertension and summarizes the current findings for GWA studies of hypertension or blood pressure.Finally,we will discuss that debate and try to find alternative strategies and technologies that may hold a greater chance to make progress in understanding the genetic risk factors of hypertension and blood pressure regulation.
文摘The study had the objective of exploring the feasibility of using the self-report SDQ-Y (youth version of strengths and difficulties questionnaire) to assess the emotional and behavioural well being of adolescents in Zambia. This was a cross sectional study of Lusaka school children (n = 420) aged 11-15 years using the self-report SDQ-Y and a demographic questionnaire. It was found that compared to a UK normative sample, Zambian adolescents were almost twice as likely to have total difficulties scores in the abnormal range (O.R. 1.9). It was found that there was a significant difference in the total SDQ scores (Z = -2.67, P = 0.008) with children reporting health problems having significantly higher scores. Children reporting health problems also had significantly more emotional problems (Z = -2.78, P = 0.005). There was a trend for children with health problems to score higher on the hyperactivity scale (Z = -1.9 P = 0.053). The internal consistency of SDQ subscales ranged from low to moderate. It can be concluded that SDQ is a useful instrument for use with Zambian adolescents, in particular, the total difficulties score and the emotional difficulties score performed well in this sample and could potentially be used to screen for mental health problems or to examine the impact of interventions.
文摘This paper is composed of three parts.The first part presents Gile’s effort model and memory mechanism in consecutive interpreting.In the second part and the third part,the author analyzes the psychological factors that cause memory difficulties and proposes corresponding strategies on the basis of the analysis.At last,the author draws a conclusion based on the discussion of the whole paper that sufficient preparation,appropriate pressure and perceived memory can avoid memory difficulties caused by psychological factors.
文摘Introduction: Complex post-traumatic facial disfigurements are caused by civilian or ballistic trauma. Their repercussions are functional, aesthetic and psychological. The initial emergency or secondary management of facial damage is difficult. The objective is to report, through the clinical observation of three patients, the results of the management of complex facial dislocations in a context of limited technical resources. Patients and methods: Three complex post-traumatic facial dislocations were managed between May 2006 and June 2017. Results: Primary treatment and secondary repair were established on a case-by-case basis. Local autoplasty was the indication of choice. Multidisciplinary management resulted in satisfactory functional and cosmetic outcomes. Two of the patients were lost to follow-up before the end of treatment. Discussion: The complete management of facial dislocations remains difficult and complex, in an extreme exercise situation. In an emergency, the priority is to save the life of the injured person. Several factors are involved in the therapeutic decision: the choice of the maxillofacial reconstruction technique, the availability of the technical platform, the financial capacity and the psychological state of the patient and his entourage. Sequential and multidisciplinary treatment gives satisfactory results in terms of morphology, function and aesthetics, despite the limited technical resources available. Psychological support is an essential complement for successful socio-professional and family reintegration.
文摘Background: Male sexual or coital difficulties are among the factors contributing to infertility in couples seeking fertility as this may result in low coital frequency. Aims/Objectives: To evaluate the causes of male sexual or coital difficulties among couples attending the infertility clinic at BSUTH, Makurdi over a 2 year period. Methodology: This was a cross-sectional study involving all males attending the infertility clinic at Benue State University Teaching Hospital (BSUTH) who consent to participate in the study. A pretested structured questionnaire was administered and analyzed with statistical package for social sciences (version 23.0) and the results were presented in simple proportions. Results: There were several factors responsible for male coital difficulties. The most common was male erectile dysfunction 33 (32.4%), vaginismus 11 (10.8%), penile pain 14 (13.7%), poor response from the female partner 8 (7.8%) and severe dyspareunia 18 (17.1%). Conclusion: Coital difficulties resulting to low frequency of sexual exposure constitutes a major cause of infertility among males attending the infertility clinic at BSUTH, Makurdi. Therefore efforts should be made to evaluate these factors while assessing infertility couples in order to mitigate the effect.

文摘Through in-depth interviews and questionnaires,we take Mianyang City,Aba Prefecture,and Suining City in Sichuan Province as the study object,to analyze the relationship between the basic situation of farmers and the supply mechanism implementation of rural public goods.The research results show that the younger the farmers,the higher the educational level,the higher the annual household income,and the higher the enthusiasm in participating the discussion of the supply of rural public goods.And the correlation between farmers'annual household income and participation in the supply of public goods is the highest.Finally corresponding countermeasures and proposals are put forth based on farmers' educational level and annual household income,the two difficulties in supply mechanism implementation of rural public goods.
文摘We developed a Virtual Shopping Test with three different task levels for assessment of daily cognitive function using virtual reality technology. The objective of present study was to investigate the difference on task performance, brain activation and subjective assessment in relation to the difficulty levels of the tasks. Subjects were asked to buy specific 2 items in Task 1, 4 items in Task 2, and 6 items in Task 3 at a virtual mall. The tasks and questionnaires were conducted on 10 convalescent brain-damaged patients and 6 healthy young adults. Hemodynamic changes in the prefrontal cortex (PFC) during activation due to the tasks were examined using functional near-infrared spectroscopy. As the result, the mean total time was significantly longer for the patients than for healthy subjects. PFC showed a greater response for related Task 2 than Task 1 in shopping and moving phase in patient group. The patients evaluated Tasks 1 and 2 are more difficult and bring more psychological load than healthy adults subjectively. That is, although the healthy adults did not show large difference in their task performances as well as PFC responses, they can evaluate the differences between three task levels, subjectively, while which could not be for the patients means that patients could not distinguish the difference of the tasks, subjectively. The results suggest that 4-item shopping task might be enough difficulty level that causes brain activation for the brain-damaged patients.
文摘Environmental pollution has caused wide social concern,and it demands immediate attention to striking at the crime in the environmental pollution. At present,there are difficulties of putting a case on file,collecting evidence,judicial identification,and presumption of causal relationship in investigation of environmental pollution cases. In accordance with current situations,it came up following recommendations:(i) widely collecting case clues to solve the difficulty of putting a case on file;(ii) improving the ability of collecting evidence and standardizing the evidence collection,to solve the difficulty of evidence collection.(iii) including the environmental pollution judicial identification system,and unifying the identification standards,to solve the difficulty in identification. It is recommended to use the epidemiological causal relationship theory combined with enough high-quality evidences to solve the difficulty in presumption of causal relationship.
文摘The Strengths and Difficulties Questionnaire (SDQ) is a brief screening measure of emotional and behavioural difficulties in children and adolescents. The aim of this study was to assess reliability and validity of the Greek version of the SDQ. A representative Greek sample of 1194 adolescents (aged 11 to 17 years) and their parents completed the SDQ along with other measures. Internal consistency reliability was determined by calculation of the Cronbach α coefficient. Varimax Orthogonal Transformation was conducted to test the factor structure of the questionnaire. Validity was further examined by investigating the correlation of the SDQ with the KIDSCREEN questionnaire and its association with demographic factors. The inter-rater agreement between parent and self-reports was analyzed with Pearson’s correlation coefficient. Intra-class correlation coefficients (ICCs) were computed to determine test-retest stability. For both parent and the self-report SDQ versions, most items loaded onto their predicted factors in consistency with the originally proposed five-factor structure. Internal consistency reliability was acceptable with a Cronbach α above 0.70 for all SDQ scales except for conduct and peer problems. Inter-rater correlations ranged from 0.33 to 0.45. Test-retest stability was good (ICCs > 0.60). Correlation coefficients between the SDQ and KIDSCREEN questionnaire were significant. Small effect sizes (d > 0.5) of the socioeconomic status were found for all of the SDQ scale mean scores. In conclusion, the SDQ was found to have satisfying psychometric properties and could be suitable for assessing emotional and behavioural problems in Greek adolescents.
文摘This paper expounds the great significance of irrigation and water conservancy for the agricultural development. Vigorously developing irrigation and water conservancy can promote high yield and stable yield of grain, effectively increase farmers' income, alleviate the impact of drought on agricultural production, be conducive to the adjustment of agricultural production structure, and promote county economic development. The difficulties of developing irrigation and water conservancy in new era are analyzed as follows: the subject of liabilities defaults seriously; it lacks effective input security system; the quality of project degenerates badly; the agricultural technological development is slow. Corresponding policy suggestions are put forward as follows: make the input subject of irrigation and water conservancy clear; form stable investment channels; strengthen the organizing and guiding functions of grass-roots government; reinforce the coordination and management of capital; strengthen the promotion of agricultural technology; quicken the pace of reform of irrigation and water conservancy.
文摘First described embryo fetopathy, congenital syphilis remains a public health problem mostly in developing countries. The diagnosis mainly based on bacteriological and immunological evidence of mother-child couple is not always easy, as it is shown in our three clinical cases. Those three clinical observations demonstrate the difficulties encountered in the diagnosis of congenital syphilis in our country where only the TPHA (Treponema Pallidum Haemaglutination Assay) and VDRL (Venereal Disease Research Laboratory) tests are the only ones to be routinely carried out. Actually, these tests can be negative at the earliest stage of the syphilis or in case of zonal phenomenon. In addition, maternal antibodies could be found in child blood, even if the baby is in good health. At last, the child could have been contaminated belatedly while tests were negative at the third month of pregnancy. Congenital syphilis still exists in our developing countries and, in order to better manage this pathology, a proposition of an efficient algorithm is submitted.
文摘Unsafe abortions constitute a public health problem. It is one of the causes of maternal mortality in the world and particularly in developing countries. Despite the progress made, maternal mortality remains high in Cameroon. The scarcity and disparity of data on abortions lead to a lack of strong evidence to advocate to decision-makers on the extent of the problems associated with abortions in Cameroon. Our objective is to estimate the rates of mortalities and complications related to unsafe abortions, as well as the difficulties of accessing safe abortions in Cameroon. We will carry out a systematic and meta-analytical review in the biomedical databases MEDLINE (Pubmed), Google Scholar and African Journal Online (AJOL) concerning unsafe abortions and/or difficulties in accessing safe abortions in Cameroon, without date or language restriction. Gray literature will be also consulted. Two authors will simultaneously select the studies and data extraction will be done using a Google Form. Proportions will be estimated on a random-effect model. The I<sup>2</sup> and Q statistics will be used to assess the extent of heterogeneity across the studies. The outcome of both the quantitative and qualitative parts of the study will be commented. Death and morbidity due to abortions can be prevented. A concerted multidisciplinary and multicentric action would be essential.
