    Background Pneumonia, diarrhoea, and malaria are among the leading causes of death in children. These deaths are largely preventable if appropriate care is sought early. This review aimed to determine the percentage of caregivers in low- and middle-income countries (LMICs) with a child less than 5 years who were able to recognise illness in their child and subsequently sought care from different types of healthcare providers. Methods and Findings We conducted a systematic literature review of studies that reported recognition of, and/or care seeking for episodes of diarrhoea, pneumonia or malaria in LMICs. The review is registered with PROSPERO (registration number: CRD42011001654). Ninety-one studies met the inclusion criteria. Eighteen studies reported data on caregiver recognition of disease and seventy-seven studies on care seeking. The median sensitivity of recognition of diarrhoea, malaria and pneumonia was low (36.0%, 37.4%, and 45.8%, respectively). A median of 73.0% of caregivers sought care outside the home. Care seeking from community health workers (median: 5.4% for diarrhoea, 4.2% for pneumonia, and 1.3% for malaria) and the use of oral rehydration therapy (median: 34%) was low. Conclusions Given the importance of this topic to child survival programmes there are few published studies. Recognition of diarrhoea, malaria and pneumonia by caregivers is generally poor and represents a key factor to address in attempts to improve health care utilisation. In addition, considering that oral rehydration therapy has been widely recommended for over forty years, its use remains disappointingly low. Similarly, the reported levels of care seeking from community health workers in the included studies are low even though global action plans to address these illnesses promote community case management. Giving greater priority to research on care seeking could provide crucial evidence to inform child mortality programmes. PMID:24718483

    The prevalence of breast cancer has been increasing in sub-Saharan Africa over the last few years. Patients often present with late stage disease, resulting in a high mortality rate. This study aims to estimate the prevalence of breast -related symptoms in the female population of Burkina Faso. The findings can be used to advise on adequate diagnostic health services for breast symptoms to ensure early detection and down-staging of breast cancer. A cross-sectional, population based study of 996 women was conducted to investigate the proportion of women with breast-related symptoms. A semi-structured questionnaire was used to collect sociodemographic data, information about breast cancer knowledge and details about breast-related symptoms, health care seeking and medical care. Breast-related symptoms were categorised as currently present/not currently present to estimate the current prevalence of women requiring a diagnostic service. Among the 996 women, 120 reported having had a breast-related symptom in their life. Only 36 women sought medical advice and eight women had diagnostic confirmation by histological or imaging techniques. Current breast-related symptoms were reported by 33 women (3.3% of the sample). An extrapolation to Burkina Faso's female population suggests that 184,562 women are in current need of diagnostic services due to any breast-related symptoms. Imaging techniques at the community and referral level are needed in order to triage women with breast-related symptoms. Specialised services need to be strengthened to ensure appropriate diagnosis and treatment of breast diseases. Education campaigns among the general population and among health care professionals are required to increase awareness of breast cancer and improve prompt health care seeking and referral.

    Pneumonia is the main cause of child mortality world-wide and most of these deaths occur in sub-Saharan Africa (SSA). Treatment with effective antibiotics is crucial to prevent these deaths; nevertheless only 2 out of 5 children with symptoms of pneumonia are taken to an appropriate care provider in SSA. While various factors associated with care seeking have been identified, the relationship between caregivers' knowledge of pneumonia symptoms and actual care seeking for their child with symptoms of pneumonia is not well researched. Based on data from Multiple Indicator Cluster Surveys, we assessed the association between caregivers' knowledge of symptoms related to pneumonia - namely fast or difficulty breathing - and care seeking behaviour for these symptoms. We analysed data of 4,163 children with symptoms of pneumonia and their caregivers. A Chi-square tests and multivariable logistic regression was performed to assess the association between care seeking and knowledge of at least one symptom (i.e., fast or difficulty breathing). Across all 6 countries only around 30% of caregivers were aware of at least one of the two symptoms of pneumonia (i.e., fast or difficulty breathing). Our study shows that in the Democratic Republic of the Congo and Nigeria there was a positive association between knowledge and care seeking (P ≤ 0.01), even after adjusting for key variables (including wealth, residence, education). We found no association between caregivers' knowledge of pneumonia symptoms and actual care seeking for their child with symptoms of pneumonia in Central African Republic, Chad, Malawi, and Sierra Leone. These findings reveal an urgent need to increase community awareness of pneumonia symptoms, while simultaneously designing context specific strategies to address the fundamental challenges associated with timely care seeking.

    Full Text Available Abstract Background Social understandings of sexually transmitted infections and associated symptoms and care-seeking behaviour continue to lag behind advancements in biomedical diagnostics and treatment, perpetuating the burden of disease. There is a lack of research linking perceptions, experiences and care-seeking for sexual health issues, especially research conducted outside of medical settings. We aim to explore lay perceptions of STIs and how these influence experiences of genito-urinary symptoms and associated care-seeking behaviour, in women and men in Britain. Methods and design This study adopts a participant-selection variant of the explanatory sequential mixed methods design to incorporate quantitative and qualitative strands. We use data from Britain’s third National Survey of Sexual Attitudes and Lifestyles (n = 15,162 to analyse national patterns of symptom experience and care-seeking, and to identify a purposive qualitative sample. Semi-structured interviews (n = 27 following up with survey participants include a novel flash card activity providing qualitative data about infection perceptions, symptom experiences and decisions about healthcare. Quantitative and qualitative data are analysed separately using complex survey analyses and principles of Interpretative Phenomenological Analysis respectively. Data are then integrated in a subsequent phase of analysis using matrices to compare, contrast and identify silences from each method. Discussion This is an ongoing mixed methods study collecting, analysing and synthesising linked data from a national survey and follow-up semi-structured interviews. It adds explanatory potential to existing national survey data and is likely to inform future surveys about sexual health. Given the current uncertainty around service provision in Britain, this study provides timely data about symptom experiences and care-seeking behaviour which may inform future commissioning of sexual

Despite this, Japanese women are likely to hesitate seeking a specialist's medical help for their menstrual symptoms. Purpose: To study subject parameters including symptom severity, gynecological disorders, and treatments in medical care-seeking women (outpatient and women opting for self-care (nonvisit, to identify reasons why Japanese women do not see a gynecologist, and to document the benefit of gynecologist visits by assessing the impact on women's daily lives. Methods: Two online surveys were conducted among women aged 15–49 years. Sampling was structured to approximate the age and geographic distribution in Japan. Results of the first survey and part of the second survey on the overall current burden of menstrual symptoms are reported in a separate publication. Further outcomes from the second survey reported in this paper included data from the outpatient (n=274 and nonvisit (n=500 groups on symptom severity, gynecological disorders, medical treatment use, reasons for not seeking medical care, and the improvement of daily life. Results: The outpatient group tended to have greater symptom severity compared to the nonvisit group. Uterine fibroids, dysmenorrhea

    Early tuberculosis (TB) case finding and adequate chemotherapy are essential for interrupting disease transmission and preventing complications due to delayed care seeking. This study was undertaken in order to provide insights into the magnitude and determinants of patient delay. The study was conducted in rural Seru district, employing a population based unmatched case-control study design. The WHO standardized TB screening tool was used to identify presumptive TB cases among the district population ages > 15 years. Presumptive TB cases who sought care in a health facility more than 14 days after the onset of symptoms were considered cases while those who sought care within the first 14 days were classified as controls. A structured interview questionnaire was used to capture socio demographic characteristics and health care service utilization related data from the study participants. A multiple binary logistic regression model was used to identify any factor associated with patient care seeking delay. A total of 9,782 individuals were screened, of which 980 (10%, 95% CI; 9.4-10.5%) presumptive TB cases were identified. From these cases 358 (76%, 95% CI; 75.6%-76.4%) sought care within the first 14 days of the onset of symptoms with a median patient delay of 15 days, IQR (5-30 days). The most common TB suggestive symptom mentioned by the participants was night sweat 754 (76.4%) while the least common was a history of contact with a confirmed TB case in the past one year 207 (21.1%). Individuals in the 45-54 age range had lower odds of delay (AOR 0.31, 95%CI 0.15, 0.61) as compared to those 15-24 years old. First TB treatment episode (AOR16.2, 95% CI 9.94, 26.26) and limited access to either traditional or modern modes of transportation (AOR 2.62, 95% CI 1.25, 5.49) were independently associated with patient care delay. Increasing community awareness about the risks of delayed care seeking and the importance of accessing health services close to the community can

    Pneumonia is among the leading causes of avoidable deaths for young children globally. The main burden of mortality falls on children from poor and rural families who are less likely to obtain the treatment they need, highlighting inequities in access to effective care and treatment. Caretakers' illness perceptions and care-seeking practices are of major importance for children with pneumonia to receive adequate care. This study qualitatively explores the caretaker concepts of childhood pneumonia in relation to treatment seeking behaviour and health worker management in Moshi urban district, Tanzania. In May - July 2013 data was gathered through different qualitative data collection techniques including five focus group discussions (FGDs) with mothers of children under-five years of age. The FGDs involved free listing of pneumonia symptoms and video presentations of children with respiratory symptoms done, these were triangulated with ten case narratives with mothers of children admitted with pneumonia and eleven in-depth interviews with hospital health workers. Transcripts were coded and analysed using qualitative content analysis. Mothers demonstrated good awareness of common childhood illnesses including pneumonia, which was often associated with symptoms such as cough, flu, chest tightness, fever, and difficulty in breathing. Mothers had mixed views on causative factors and treatments options but generally preferred modern medicine for persisting and severe symptoms. However, all respondent reported access to health facilities as a barrier to care, associated with transport, personal safety and economic constraints. Local illness concepts and traditional treatment options did not constitute barriers to care for pneumonia symptoms. Poor access to health facilities was the main barrier. Decentralisation of care through community health workers may improve access to care but needs to be combined with strengthened referral systems and accessible hospital care for

    Men's healthcare-seeking delay results in higher mortality while on HIV or tuberculosis (TB) treatment, and implies contribution to ongoing community-level TB transmission before initiating treatment. We investigated masculinity's role in healthcare-seeking delay for men with TB-suggestive symptoms, with a view to developing potential interventions for men. Data were collected during March 2011- March 2012 in three high-density suburbs in urban Blantyre. Ten focus group discussions were carried out of which eight (mixed sex = two; female only = three; male only = three) were with 74 ordinary community members, and two (both mixed sex) were with 20 health workers. Individual interviews were done with 20 TB patients (female =14) and 20 un-investigated chronic coughers (female = eight), and a three-day workshop was held with 27 health stakeholder representatives. An expectation to provide for and lead their families, and to control various aspects of their lives while facing limited employment opportunities and small incomes leaves men feeling inadequate, devoid of control, and anxious about being marginalised as men. Men were fearful about being looked at as less than men, and about their wives engaging in extramarital sex without ability to detect or monitor them. Control was a key defining feature of adequate manhood, and efforts to achieve it also led men into side-lining their health. Articulate and consistent concepts of men's bodily strength or appropriate illness responses were absent from the accounts. Facilitating men to seek care early is an urgent public health imperative, given the contexts of high HIV/AIDS prevalence but increasingly available treatment, and the role of care-seeking delay in TB transmission. Men's struggles trying to achieve ideal images seem to influence their engagement with their health. Ambiguous views regarding some key masculinity representations and the embrace of less harmful masculinities raise questions about some common

    This study represents the first examination of adolescent anxiety in relation to peer emotion recognition, rather than adult emotion recognition. Additionally, we examine potential mechanisms for the development of Social Anxiety in females. Facial emotion recognition (FER) is important for accurate social cognition, which is impaired in individuals with various disorders, including anxiety disorders. Social anxiety often onsets during adolescence, is observed more commonly in females, and is often associated with FER difficulties. Given the importance of peer interaction during adolescence, and some evidence that FER may differ as a function of the stimuli (adolescent or adult faces), we sought to study FER in relation to social anxiety symptoms using stimuli portraying adolescent faces. Male and female adolescents (N=64) completed an online survey in which they rated 257 child and adolescent emotional faces and completed a self-report measure of social anxiety symptoms. We examined differences in emotion recognition (e.g., fear, anger, sadness) between individuals with high and low levels of social anxiety symptoms. Adolescents with high social anxiety symptoms were more likely to have problems correctly identifying fearful expressions (90.55% accuracy) compared to adolescents with low social anxiety symptoms (96.00% accuracy; t = 2.375, p = .021, d = 0.594), and this effect was observed exclusively in female adolescents. The observed sex difference in accurate identification of fearful faces in relation to social anxiety could suggest a potential mechanism for social anxiety development in adolescent females.

    Full Text Available Abstract Background Post-treatment follow-up visits for gynecological cancer survivors should provide opportunities for management of adverse physical/psychological effects of therapy and early recurrence detection. However, the adequacy of such visits in Japan is poorly documented. We qualitatively explored care-seeking experiences of Japanese gynecological cancer survivors and deduced factors influencing care-seeking behaviors and treatment access. Methods We conducted 4 semi-structured focus groups comprising altogether 28 Japanese gynecological cancer survivors to collect a variety of participants’ post-treatment care-seeking behaviors through active interaction with participants. Factors influencing access to treatment for adverse effects were analyzed qualitatively. Results Survivors sought care through specialty clinic visits when regular post-treatment gynecological follow-ups were inadequate or when symptoms seemed to be non-treatment related. Information provided by hospital staff during initial treatment influenced patients’ understanding and response to adverse effects. Lack of knowledge and inaccurate symptom interpretation delayed help-seeking, exacerbating symptoms. Gynecologists’ attitudes during follow-ups frequently led survivors to cope with symptoms on their own. Information from mass media, Internet, and support groups helped patients understand symptoms and facilitated care seeking. Conclusions Post-treatment adverse effects are often untreated during follow-up visits. Awareness of possible post-treatment adverse effects is important for gynecological cancer survivors in order to obtain appropriate care if the need arises. Consultation during the follow-up visit is essential for continuity in care.

    2015-01-01

    Full Text Available Background. Efforts to reduce child mortality especially in Africa must as a necessity aim to decrease mortality due to pneumonia. To achieve this, preventive strategies such as expanding vaccination coverage are key. However once a child develops pneumonia prompt treatment which is essential to survival is dependent on mothers and caregiver recognition of the symptoms and danger signs of pneumonia. Methods. This community based cross-sectional study enrolled four hundred and sixty-six caregivers in Enugu state. It aimed to determine knowledge of caregivers about danger signs of pneumonia and the sociodemographic factors that influence knowledge and care seeking behaviour of caregivers. Results. There is poor knowledge of the aetiology and danger signs of pneumonia among caregivers. Higher maternal educational attainment and residence in semiurban area were significantly associated with knowledge of aetiology, danger signs, and vaccination of their children against pneumonia. Fast breathing and difficulty in breathing were the commonest known and experienced WHO recognized danger signs while fever was the commonest perceived danger sign among caregivers. Conclusion. Knowledge of danger signs and health seeking behaviour among caregivers is inadequate. There is need for intensified public and hospital based interventions targeted at mothers to improve their knowledge about pneumonia.

    Full Text Available Background: Appropriate and timely care seeking reduces mortality for childhood illnesses including pneumonia. Despite over 90 000 Lady Health Workers (LHWs deployed in Pakistan, whose tasks included management of pneumonia, only 16% of care takers sought care from them for respiratory infections. As part of a community case management trial for childhood pneumonia, community mobilization interventions were implemented to improve care seeking from LHWs in Haripur district, Pakistan. The objective of the study was to increase the number of children receiving treatment for pneumonia and severe pneumonia by Lady Health Workers (LHWs through community mobilization approaches for prompt recognition and care seeking in 2 to 59 month–old children. Methods: To assess pneumonia care seeking practices, pre and post– intervention household surveys were conducted in 28 target Union Councils. Formative research to improve existing LHW training materials, job aids and other materials was carried out. Advocacy events were organized, LHWs and male health promoters were trained in community mobilization, non–functional women and male health committees were revitalized and LHWs and male health promoters conducted community awareness sessions. Results: The community mobilization interventions were implemented from April 2008 – December 2009. Project and LHW program staff organized 113 sensitization meetings for opinion leaders, which were attended by 2262 males and 3288 females. The 511 trained LHWs organized 6132 community awareness sessions attended by 50 056 women and 511 male promoters conducted 523 sessions attended by 7845 males. In one year period, the number of LHWs treating pneumonia increased from 11 in April 2008 to 505 in March 2009. The care seeking from LHWs for suspected pneumonia increased from 0.7% in pre–intervention survey to 49.2% in post–intervention survey. Conclusion: The increase in care seeking from LHWs benefited the community

  20. Acute ischemic stroke--from symptom recognition to thrombolysis.

    2013-01-01

    The understanding of stroke has changed in the recent years from rehabilitation to an emergency approach. We review existing data from symptom recognition to thrombolysis and identify challenges in the different phases of patient treatment. Implementation of treatment in dedicated stroke units with a multidisciplinary team exclusively treating stroke patients has led to significant reduction of stroke morbidity and mortality. Yet, first the introduction of treatment with intravenous rtPA (IVT) has led to the 'time is brain' concept where stroke is conceived as an emergency. As neuronal death in stroke is time dependent, all effort should be laid on immediate symptom recognition, rapid transport to the nearest hospital with a stroke treatment facility and diagnosis and treatment as soon as possible. The main cause of prehospital delay is that patients do not recognize that they suffered a stroke or out of other reasons do not call the Emergency Medical Services immediately. Educational stroke awareness campaigns may have an impact in increasing the number of patients eligible for rtPA treatment and can decrease the prehospital times if they are directed both to the public and to the medical divisions treating stroke. Stroke transport times can be shortened by the use of helicopter and a stroke mobile--an ambulance equipped with a CT scanner--may be helpful to decrease time from onset to treatment start in the future. Yet, IVT has several limitations such as a narrow time window and a weak effect in ischemic strokes caused by large vessel occlusions. In these cases, interventional procedures and the concept of bridging therapy, a combined approach of IVT and intraarterial thrombolysis or mechanical thrombectomy, might improve recanalization rates and patient outcome. As neuronal death in stroke patients occurs in a time-dependent fashion, all effort should be made to decrease time from symptom onset to treatment start with rtPA: major challenges are stroke

    Full Text Available Abstract Background Though non-communicable diseases contribute to an increasing share of the disease burden in South Asia, health systems in most rural communities are ill-equipped to deal with chronic illness. This analysis seeks to describe care-seeking behavior among women of reproductive age who died from fatal non-communicable diseases as recorded in northwest rural Bangladesh between 2001 and 2007. Methods This analysis utilized data from a large population-based cohort trial in northwest rural Bangladesh. To conduct verbal autopsies of women who died while under study surveillance, physicians interviewed family members to elicit the biomedical symptoms that the women experienced as well as a narrative of the events leading to deaths. We performed qualitative textual analysis of verbal autopsy narratives for 250 women of reproductive age who died from non-communicable diseases between 2001 and 2007. Results The majority of women (94% sought at least one provider for their illnesses. Approximately 71% of women first visited non-certified providers such as village doctors and traditional healers, while 23% first sought care from medically certified providers. After the first point of care, women appeared to switch to medically certified practitioners when treatment from non-certified providers failed to resolve their illness. Conclusions This study suggests that treatment seeking patterns for non-communicable diseases are affected by many of the sociocultural factors that influence care seeking for pregnancy-related illnesses. Families in northwest rural Bangladesh typically delayed seeking treatment from medically certified providers for NCDs due to the cost of services, distance to facilities, established relationships with non-certified providers, and lack of recognition of the severity of illnesses. Most women did not realize initially that they were suffering from a chronic illness. Since women typically reached medically certified

    Globally, around 16% of under-five children die due to pneumonia. Childhood pneumonia, if identified early is a readily treatable through low-cost antibiotics. Access to timely and appropriate care is a key action to control pneumonia. The aim of the study was to understand the caregiver's care-seeking behavior for the management of childhood pneumonia among rural and urban poor communities in Lucknow. Rural areas and urban slums of Lucknow district, from September 2014 to August 2015. A community-based cross-sectional study. Total of 1065 under-five children were selected by multistage random sampling method. Caregivers of children (care at onset of illness. Appearance of chest indrawing in the child was identified by caregivers as a serious condition and sought treatment from outside. The mean time taken from onset of illness to the seeking care from health facility was around 2½ days (2.39 ± 0.75). Qualified private practitioners (70.5%) were the preferred choice and majority (87.0%) of the children received antibiotic for pneumonia. However, even after perception of seriousness of the illness, 26.8% and 11.1% caregivers in urban slums and rural areas, respectively sought inappropriate care at the first consultation. Caregivers were unable to perceive the severity of fast breathing leading to the delayed initiation of the appropriate treatment. There is a need of community mobilization through behavior change communication interventions to promote early symptom recognition and appropriate care seeking for pneumonia.

    This cross-sectional study assessed the health-care-seeking behaviour, barriers to accessing care and associated factors among a sample of 543 Lebanese students at Saint-Joseph University. Data were collected on health-care-seeking behaviour for health issues in the previous 12 months using an anonymous questionnaire. Health-care-seeking behaviour was categorized as: formal (professional help sought); informal relational (help sought from friends/family); informal personal (self-help). The health issues examined were: physical, psychological, social and relational, sexual, drug, alcohol and smoking. When facing health-related issues, the students tended to seek informal health care. Formal health-care-seeking behaviour was almost non-existent for psychological issues (3.3%), relational and social issues (1.8%), and issues related to substance use (5.1%). The barriers to seeking formal health care fell into 2 categories: accessibility and relational. To encourage young people to access formal health care, specific health services should be provided for them where they are assured of confidentiality and understanding.

    Once malaria occurs, deaths can be prevented by prompt treatment with relatively affordable and efficacious drugs. Yet this goal is elusive in Africa. The paradox of a continuing but easily preventable cause of high mortality raises important questions for policy makers concerning care-seeking and access to health systems. Although patterns of care-seeking during uncomplicated malaria episodes are well known, studies in cases of fatal malaria are rare. Care-seeking behaviours may differ between these groups. This study documents care-seeking events in 320 children less than five years of age with fatal malaria seen between 1999 and 2001 during over 240,000 person-years of follow-up in a stable perennial malaria transmission setting in southern Tanzania. Accounts of care-seeking recorded in verbal autopsy histories were analysed to determine providers attended and the sequence of choices made as the patients' condition deteriorated. As first resort to care, 78.7% of malaria-attributable deaths used modern biomedical care in the form of antimalarial pharmaceuticals from shops or government or non-governmental heath facilities, 9.4% used initial traditional care at home or from traditional practitioners and 11.9% sought no care of any kind. There were no differences in patterns of choice by sex of the child, sex of the head of the household, socioeconomic status of the household or presence or absence of convulsions. In malaria deaths of all ages who sought care more than once, modern care was included in the first or second resort to care in 90.0% and 99.4% with and without convulsions respectively. In this study of fatal malaria in southern Tanzania, biomedical care is the preferred choice of an overwhelming majority of suspected malaria cases, even those complicated by convulsions. Traditional care is no longer a significant delaying factor. To reduce mortality further will require greater emphasis on recognizing danger signs at home, prompter care-seeking

    Child undernutrition affects millions of children globally, but little is known about the ability of adults to detect different types of child undernutrition in low-income countries. We used focused ethnographic methods to understand how Malawian parents and grandparents describe the characteristics they use to identify good and poor child growth, their actual or preferred patterns of health seeking for undernourished children, and the perceived importance of child undernutrition symptoms in relation to other childhood illnesses. Malawians value adiposity rather than stature in assessing child growth. Symptoms of malnutrition, including wasting and edema, were considered the least severe childhood illness symptoms. Parents delayed health care seeking when a child was ill. When they sought care, it was for symptoms such as diarrhea or fever, and they did not recognize malnutrition as the underlying cause. These findings can be used to tailor strategies for preventing and treating growth faltering in Malawian children. © The Author(s) 2015.

    Cross-cultural studies have demonstrated universal similarity in the recognition and expression of basic emotions in facial expressions. The so-called mood congruency effect, observed primarily in clinical populations, implies that subjects with depressed mood tend to judge positive emotions as neutral and neutral faces as negative. The objective was to investigate whether a mood congruency effect can be detected in case of mild impairments among healthy subjects. First, it was hypothesized that subjects with mild psychiatric symptom distress have poorer performance in affective facial recognition in general. Second, it was also hypothesized that these subjects have poorer functioning in neutral face recognition and that they are prone to attribute negative emotions, for example, sadness and fear to neutral faces. Third, it was also assumed that people with mild psychiatric symptom distress have poor performance in recognizing positive emotions. Pictures representing the basic emotions were used to examine the recognition of facial emotions; the Symptom Checklist-90 was obtained to quantify overall psychological distress and the severity of psychiatric symptoms on 9 primary symptom dimensions, including somatization, obsessive-compulsive, interpersonal sensitivity, depression, anxiety, hostility, phobic anxiety, paranoid ideation, and psychoticism. One hundred seventeen healthy volunteers were recruited for the purpose of the study. Consistent with the first hypothesis, results indicated a significant negative association between the overall recognition rate of facial expressions and the level of psychiatric symptoms in a healthy population. Consistent with the second hypothesis, the level of psychiatric symptoms was related inversely with the neutral facial expression recognition and directly with the negative bias in neutral facial expressions. However, our data did not support the assumption that people with mild psychiatric symptom distress would have a poorer

    Full Text Available Pneumonia is the leading cause of childhood mortality in sub-Saharan Africa (SSA. Because effective antibiotic treatment exists, timely recognition of pneumonia and subsequent care seeking for treatment can prevent deaths. For six high pneumonia mortality countries in SSA we examined if children with suspected pneumonia were taken for care, and if so, from which type of care providers, using national survey data of 76530 children. We also assessed factors independently associated with care seeking from health providers, also known as 'appropriate' providers. We report important differences in care seeking patterns across these countries. In Tanzania 85% of children with suspected pneumonia were taken for care, whereas this was only 30% in Ethiopia. Most of the children living in these six countries were taken to a primary health care facility; 86, 68 and 59% in Ethiopia, Tanzania and Burkina Faso respectively. In Uganda, hospital care was sought for 60% of children. 16-18% of children were taken to a private pharmacy in Democratic Republic of Congo (DRC, Tanzania and Nigeria. In Tanzania, children from the richest households were 9.5 times (CI 2.3-39.3 more likely to be brought for care than children from the poorest households, after controlling for the child's age, sex, caregiver's education and urban-rural residence. The influence of the age of a child, when controlling for sex, urban-rural residence, education and wealth, shows that the youngest children (<2 years were more likely to be brought to a care provider in Nigeria, Ethiopia and DRC. Urban-rural residence was not significantly associated with care seeking, after controlling for the age and sex of the child, caregivers education and wealth. The study suggests that it is crucial to understand country-specific care seeking patterns for children with suspected pneumonia and related determinants using available data prior to planning programmatic responses.

    To assess the accuracy of oncology nurses' recognition of supportive care needs and symptoms of their patients undergoing chemotherapy. The participants comprised randomly selected cancer outpatients receiving chemotherapy in an ambulatory setting and 17 oncology nurses working in two chemotherapy units in Japan. For assessment of the patients' supportive care needs and symptoms, the patients were asked to respond to a validated self-administered questionnaire. The oncology nurses completed a survey in which they indicated their perception of the level of the same set of needs or symptoms. The two data sets obtained from the patients and nurses were compared statistically to assess the accuracy of the oncology nurses' recognition of their patients' needs and symptoms. Complete data sets were available for 439 patients. The most common primary cancers were breast cancer (36.0%), followed by colorectal (24.4%) and lung (12.3%) cancers. Nurses' awareness of their patients' supportive care needs and physical and psychological symptoms were less than optimal in routine care. In particular, psychological symptoms and support needs for these symptoms were markedly under-recognized. Physical symptoms associated with chemotherapy, such as hair loss, appetite loss and fatigue, were better recognized than symptoms not specific to chemotherapy, such as constipation, insomnia, dyspnea and pain. Oncology nurses' recognition may not accurately reflect their patients' supportive care needs and symptoms in routine practice. In clinical practice, it may be beneficial to conduct routine screening of patients' perceived needs and symptoms comprehensively using self-administered questionnaires.

    Delay by men in seeking healthcare results in their higher mortality while on HIV or tuberculosis (TB) treatment and contributes to ongoing community-level disease transmission before going on treatment. To understand masculinity's role in delay in healthcare seeking for men, with a focus on TB-suggestive symptoms. Data were collected between March 2011 and March 2012 in low-income suburbs in urban Blantyre using focus group discussions with community members (n=8) and health workers (n=2), in-depth interviews with 20 TB patients (female=14) and 20 uninvestigated chronic coughers (female=8), and a 3-day participatory workshop with 27 health stakeholder representatives. The research process drew to a large extent on grounded theory principles in the manner of Strauss and Corbin (1998) and also Charmaz (1995). Role descriptions by both men and women in the study universally assigned men as primary material providers for their immediate family, that is, the ones earning and bringing livelihood and additional material needs. In a context where collectivism was valued, men were also expected to lead the provision of support to wider kin. Successful role enactment was considered key to achieving recognition as an adequate man; at the same time, job scarcity and insecurity, and low earnings gravely impeded men. Pressures to generate continuing income then meant constantly looking for jobs, or working continuously to retain insecure jobs or to raise money through self-employment. All this led men to relegate their health considerations. Early engagement with formal healthcare is critical to dealing with TB and HIV. However, role constructions as portrayed for men in this study, along with the opportunity costs of acknowledging illness seem, in conditions of vulnerability, important barriers to care-seeking. There is a need to address hidden care-seeking costs and to consider more complex interventions, including reducing precarity, in efforts to improve men's engagement

    Cardiovascular diseases are the number one cause of death and a source of chronic disability. To assess recognition of and reaction to symptoms of heart attack and stroke, and how recognition is related to the frequency of consulting physicians and other information sources. Face-to-face computer-assisted personal interviews. Representative sample of 10,228 persons in Austria, France, Germany, Italy, the Netherlands, Poland, Russia, Spain and UK, aged 14-98. Recognition of heart attack and stroke symptoms and proper reaction to symptoms. Chest pain was the only heart attack symptom recognized by more than 50% of participants. Eight percent knew no symptoms. Of 14 stroke symptoms, none was recognized by more than 50% of participants; 19% could not identify any symptom. For both heart attack and stroke, Germans and Austrians recognized the largest number of symptoms. Persons in Italy, Poland, Russia and Spain knew only about half as many symptoms as in Germany or Austria. Only 51% of Europeans would call an ambulance when someone suffers a stroke, the fewest (33 and 34%) in Germany and Austria. In most countries, people who consulted their physician more frequently had no better recognition of heart attack or stroke symptoms. The majority of persons in nine European countries recognize few heart attack and stroke symptoms; many do not know how to react. This low level of knowledge constitutes a major health risk and likely leads to delay in treatment, contributing to the high mortality and morbidity from these diseases. © 2012 John Wiley & Sons Ltd.

Less consistent data are available on the emotion recognition in adolescents with externalization problems. The aim of the present study was to assess the relation between the recognition of emotions and conduct symptoms in adolescent boys with externalization problems. Methods. Adolescent boys with externalization problems referred to Vadaskert Child Psychiatry Hospital participated in the study after informed consent (N=114, 11–17 years, mean = 13.4. The conduct problems scale of the strengths and difficulties questionnaire (parent and self-report was used. The performance in a facial emotion recognition test was assessed. Results. Conduct problems score (parent and self-report was inversely correlated with the overall emotion recognition. In the self-report, conduct problems score was inversely correlated with the recognition of anger, fear, and sadness. Adolescents with high conduct problems scores were significantly worse in the recognition of fear, sadness, and overall recognition than adolescents with low conduct scores, irrespective of age and IQ. Conclusions. Our results suggest that impaired emotion recognition is dimensionally related to conduct problems and might have importance in the development of antisocial behavior.

    In 2014, USAID and University Research Co., LLC, initiated a new project under the broader Translating Research into Action portfolio of projects. This new project was entitled Systematic Documentation of Illness Recognition and Appropriate Care Seeking for Maternal and Newborn Complications. This project used a common protocol involving descriptive mixed-methods case studies of community projects in six low- and middle-income countries, including Ethiopia. In this paper, we present the Maternal and Newborn Health in Ethiopia Partnership (MaNHEP) case study. Methods included secondary analysis of data from MaNHEP's 2010 baseline and 2012 end line surveys, health program inventory and facility mapping to contextualize care-seeking, and illness narratives to identify factors influencing illness recognition and care-seeking. Analyses used descriptive statistics, bivariate tests, multivariate logistic regression, and thematic content analysis. Maternal illness awareness increased between 2010 and 2012 for major obstetric complications. In 2012, 45% of women who experienced a major complication sought biomedical care. Factors associated with care-seeking were MaNHEP CMNH Family Meetings, health facility birth, birth with a skilled provider, or health extension worker. Between 2012 and 2014, the Ministry of Health introduced nationwide initiatives including performance review, ambulance service, increased posting of midwives, pregnant women's conferences, user-friendly services, and maternal death surveillance. By 2014, most facilities were able to provide emergency obstetric and newborn care. Yet in 2014, biomedical care-seeking for perceived maternal illness occurred more often compared with care-seeking for newborn illness-a difference notable in cases in which the mother or newborn died. Most families sought care within 1 day of illness recognition. Facilitating factors were health extension worker advice and ability to refer upward, and health facility proximity

Men with GUD (n = 615) were recruited from primary health care clinics in Gauteng province, South Africa for a randomized controlled trial of episodic acyclovir therapy. We used baseline survey and sexually transmitted infection/HIV-testing data to examine delay in health care seeking (defined as time from ulcer recognition to baseline study visit). Median delay in health care seeking for GUD was 5 days, and one-quarter of men had previously sought care for the current ulcer. Previous care seekers were older, had more episodes of ulceration in the past year, and were more likely to test seropositive for HIV-1 and HSV-2. Delay in health care seeking was significantly associated with age, education level, and sex during the ulceration episode. Delays in care seeking were related to poorer HIV-1 outcomes; these findings were valid after controlling for advanced HIV. Interventions to help shorten the duration between ulcer recognition and health care seeking for men with GUD are needed.

    The authors report the highlights of a one-day symposium, "Academic Medicine and Managed Care: Seeking Common Ground," sponsored in early 1997 by Tulane University Medical Center. The meeting was held to foster better understanding of the gap between managed care organizations (MCOs) and academic health centers (AHCs) and to define their common ground. There were 62 participants, mainly executives froin AHCs and MCOs, plus government officials and policy researchers interested in the interface of academic medicine and managed care. The participants agreed that there are indeed some common areas in which the two types of organizations can develop programs and interests that serve the missions of both. These include (1) a commitment to high-quality health care, objectively measured by outcomes; (2) issues of "customer service"; (3) certain areas of research (e.g., examining outcomes of medical interventions; measuring cost and cost-effectiveness; measuring quality of care); and (4) preventive medicine, an area in which both AHCs and MCOs are still relatively weak. On the other hand, large elements of AHCs' basic missions of education and research are not seen by MCOs as areas for developing a common agenda. Participants agreed that AHCs must do their best to improve and demonstrate the quality of their care, address the challenges of the market (i.e., take "customer service" seriously), address the issue of how many specialists and how many generalists should be trained, and define the cost of each of their missions. On the other hand, managed care must acknowledge that the missions of AHCs greatly benefit patients and society. Participants agreed that all approaches to AHC-MCO interfaces must be flexible and local, that common ground does exist, and that understanding can grow between these two kinds of organizations if acrimonious exchanges are avoided and serious efforts are made to work together for solutions.

    South African infant and child mortality remains high, with many deaths occurring outside the formal health services. Delayed health care seeking represents a large proportion of these deaths. To generate knowledge about the role of, and influences on, caregivers with regard to decision-making about when and where to seek care for sick children. Two communities in KwaZulu-Natal. A qualitative, exploratory design employing participatory research techniques was used to undertake focus group discussions with community members. Health care seeking for a sick child was described as a complex process influenced by multiple carers using multiple providers. Decision-making about seeking health care for a sick child was not an individual effort, but was shared with others in the household and guided by how the symptoms were perceived, either a Western illness or African illness. A sick child could either be treated at home or be taken to a variety of places including clinics, private doctors, traditional healers, faith healers and hospitals. Traditional healers were associated with the treatment of illnesses perceived to be traditional. Few participants said that they would take their child back to the original health provider if the child remained ill, but would move from one provider to another until the child's health improved. The formal health system needs to ensure that sick children are identified and managed appropriately to reduce child deaths. Knowledge and understanding of health care seeking behaviour for sick children by carers is an important aspect. Interventions need to be designed with these contextual issues in mind.

    Timely diagnosis and treatment initiation are critical to reduce the chain of transmission of Tuberculosis (TB) in places like Mumbai, where almost 60% of the inhabitants reside in overcrowded slums. This study documents the pathway from the onset of symptoms suggestive of TB to initiation of TB treatment and examines factors responsible for delay among uncomplicated pulmonary TB patients in Mumbai. A population-based retrospective survey was conducted in the slums of 15 high TB burden administrative wards to identify 153 self-reported TB patients. Subsequently in-depth interviews of 76 consenting patients that fit the inclusion criteria were undertaken using an open-ended interview schedule. Mean total, first care seeking, diagnosis and treatment initiation duration and delays were computed for new and retreatment patients. Patients showing defined delays were divided into outliers and non-outliers for all three delays using the median values. The mean duration for the total pathway was 65 days with 29% of patients being outliers. Importantly the mean duration of first care seeking was similar in new (24 days) and retreatment patients (25 days). Diagnostic duration contributed to 55% of the total pathway largely in new patients. Treatment initiation was noted to be the least among the three durations with mean duration in retreatment patients twice that of new patients. Significantly more female patients experienced diagnostic delay. Major shift of patients from the private to public sector and non-allopaths to allopaths was observed, particularly for treatment initiation. Achieving positive behavioural changes in providers (especially non-allopaths) and patients needs to be considered in TB control strategies. Specific attention is required in counselling of TB patients so that timely care seeking is effected at the time of relapse. Prioritizing improvement of environmental health in vulnerable locations and provision of point of care diagnostics would be

    Malaria is a major cause of under-five mortality in Mali and many other developing countries. Malaria control programmes rely on households to identify sick children and either care for them in the home or seek treatment at a health facility in the case of severe illness. This study examines the involvement of mothers and other household members in identifying and treating severely ill children through case studies of 25 rural Malian households. A wide range of intra-household responses to severe illness were observed among household members, both exemplifying and contravening stated social norms about household roles. Given their close contact with children, mothers were frequently the first to identify illness symptoms. However, decisions about care-seeking were often taken by fathers and senior members of the household. As stewards of the family resources, fathers usually paid for care and thus significantly determined when and where treatment was sought. Grandparents were frequently involved in diagnosing illnesses and directing care towards traditional healers or health facilities. Relationships between household members during the illness episode were found to vary from highly collaborative to highly conflictive, with critical effects on how quickly and from where treatment for sick children was sought. These findings have implications for the design and targeting of malaria and child survival programming in the greater West African region.

    Impairments in facial emotion recognition (FER) have been detected in patients with Parkinson disease (PD). Presently, we aim at assessing differences in emotion recognition performance in PD patient groups with and without mild forms of cognitive impairment (MCI) compared to healthy controls. Performance on a concise emotion recognition test battery (VERT-K) of three groups of 97 PD patients was compared with an age-equivalent sample of 168 healthy controls. Patients were categorized into groups according to two well-established classifications of MCI according to Petersen's (cognitively intact vs. amnestic MCI, aMCI, vs. non-amnestic MCI, non-aMCI) and Litvan's (cognitively intact vs. single-domain MCI, sMCI, vs. multi-domain MCI, mMCI) criteria. Patients and controls underwent individual assessments using a comprehensive neuropsychological test battery examining attention, executive functioning, language, and memory (Neuropsychological Test Battery Vienna, NTBV), the Beck Depression Inventory, and a measure of premorbid IQ (WST). Cognitively intact PD patients and patients with MCI in PD (PD-MCI) showed significantly worse emotion recognition performance when compared to healthy controls. Between-groups effect sizes were substantial, showing non-trivial effects in all comparisons (Cohen's ds from 0.31 to 1.22). Moreover, emotion recognition performance was higher in women, positively associated with premorbid IQ and negatively associated with age. Depressive symptoms were not related to FER. The present investigation yields further evidence for impaired FER in PD. Interestingly, our data suggest FER deficits even in cognitively intact PD patients indicating FER dysfunction prior to the development of overt cognitive dysfunction. Age showed a negative association whereas IQ showed a positive association with FER.

    A major public health concern in India is the high morbidity and mortality rates of oral cancer because of late diagnosis. Among the several determinants of this late diagnosis, the most important is the healthcare-seeking behaviour of the oral cancer patients. The aim of this study was to explore the care-seeking behaviour and its determinants among oral cancer patients. A face-to-face in-depth interview was conducted among 70 oral cancer patients using a semi-structured questionnaire, and qualitative content analysis of the results was performed. All the patients had squamous-cell carcinoma and none had attended any screening programme. The most common site affected was the buccal mucosa with a non-healing wound. Most of the patients contacted a doctor available nearby; only 7% of patients consulted a dentist. Only one patient approached a traditional healer. The median patient delay was 30 (4-365) days and the professional delay was 40 (4-650) days. Enablers included determinants such as increasing symptoms (80%), influence of the society (74%), fear (10%), and social media (3%). The main barriers were lack of awareness (97%), hope that the lesion will heal spontaneously (90%), lack of perception of seriousness (64%), financial constraints (55%), provider switching (47%), and missed diagnosis (44%). The care-seeking path among oral cancer patients is complex, customised, and influenced by multiple patient-related and system-related factors. Copyright © 2018. Published by Elsevier Ltd.

Dementia was checked with the Mini Mental State Examination, Clinical Dementia Rating scale, and DSM IV. Recognition of emotional prosody was tested by asking subjects to listen to 12 recorded statements with neutral affective content that were read with a strong affective expression. Subjects had to recognize the correct emotion by one of four descriptors (angry, sad, cheerful, and neutral. The Beck Depression Inventory (BDI was employed to rate depressive symptoms with the cutoff 14.Results: Total ratings of emotions correctly recognized by participants below and above the BDI cutoff were similar among PD patients and normal individuals. PD patients who correctly identified neutral and anger inflections presented higher rates of depressive symptoms (p = 0.011 and 0.044, respectively. No significant differences were observed in the normal group.Conclusions: Depression may modify some modalities of emotional prosody perception in PD, by increasing the perception of non-pleasant emotions or lack of affection, such as anger or indifference.Keywords: emotional prosody, Parkinson’s disease, depression, emotion

    The ability to seek help or medical care for sexually transmitted infections (STIs) is vital for sexually active youth; yet, their needs are often unmet. We conducted a qualitative systematic review of studies to assess youth and provider views about the behaviors of young people in help seeking and care seeking for STI services in low- and middle-income countries. We searched peer-reviewed literature for studies published between 2001 and 2014 with a study population of youth (age, 10-24 years) and/or health service providers. Eighteen studies were identified for inclusion from 18 countries. Thematic analyses identified key themes across the studies. The majority of studies included discussion of youth not seeking treatment, resorting to self-treatment, or waiting to access care, suggesting that many youth still do not seek timely care for STIs. Youth desired more information on sexual health and cited barriers related to fear or taboos in obtaining help or information, especially from providers or parents. Many did not recognize symptoms or waited until symptoms worsened. However, many youth were able to identify a number of sources for STI related care including public and private clinics, pharmacies, alternative healers, and nongovernmental organizations. Youth's help seeking and care seeking preferences were frequently influenced by desires for confidentiality, friendliness, and cost. Youth in low- and middle-income countries experience significant barriers in help seeking for STIs and often do not seek or postpone medical care. Improving uptake may require efforts to address clinic systems, provider attitudes, confidentiality, and cultural norms related to youth sexuality.

    One of the most striking features of the ongoing conflict in the Democratic Republic of Congo (DRC) is the use of sexual violence. In spite of the brutality of these crimes, the experiences of women affected by sexual violence in Eastern DRC remain poorly characterized. This analysis aimed to (1) provide detailed demographics of sexual violence survivors presenting to Panzi Hospital; (2) examine how demographic factors might impact patterns of sexual violence; and (3) describe care-seeking behavior among sexual violence survivors. The demographics and care-seeking behavior of sexual violence survivors in South Kivu Province were described from a retrospective registry-based study of sexual violence survivors presenting to Panzi Hospital (2004-2008). A total of 4311 records were reviewed. The mean age of survivors was 35 years. Most women (53%) were married, self-identified with the Bashi tribe (65%), and reported agriculture as their livelihood (74%). The mean time delay between sexual assault and seeking care was 10.4 months. Five reasons were identified to help explain the lengthy delays to seeking care: waiting for physical symptoms to develop or worsen before seeking medical attention, lack of means to access medical care, concerns that family would find out about the sexual assault, stigma surrounding sexual violence, and being abducted into sexual slavery for prolonged periods of time. Many sexual assault survivors have very delayed presentations to medical attention. Promoting timely access of medical care may best be facilitated by reducing stigma and by educating women about the benefits of early medical care, even in the absence of injuries or symptoms.

    Well-known risk factors, such as smoking and alcohol consumption, easily denounce head and neck cancer patients as smokers, alcohol abusers, and persons who are socially excluded and have low socioeconomic status. To diagnose these patients as early as possible, we should not have a prejudiced assumption of their characteristics. We collected detailed data on patient characteristics and health behavior and explored whether these traits had any effect on seeking medical advice in a population-based cross-sectional study involving 85 patients with head and neck cancer diagnosed between January 2003 and December 2007, residing in two health care districts (population 1,600,000) in Finland. The data were gathered from patient charts and questionnaires. The questionnaire data were compared with the general population in Finland. We found these patients to be ordinary elderly people whose demographic and social features resembled those of the general population. They smoked more often, but otherwise had a rather healthy lifestyle. Only half were aware that smoking and alcohol consumption were risk factors of head and neck cancer. In a multivariate analysis, fear of physicians (adjusted odds ratio 11.0; 95% confidence interval 1.2-103), medical-care-seeking for symptoms other than pain (18.5; 2.2-156), and not suspecting cancer (11.2; 1.7-75.1) were independent risk factors for delayed consultation (combined appraisal and help-seeking interval over 3 months). Head and neck cancer patients deviated from the same-aged general population only in excessive smoking. Fear of doctors, having no pain, and no suspicion of cancer resulted in delayed medical-care-seeking. Copyright © 2014 Elsevier Ltd. All rights reserved.

    Canadians' health care-seeking behaviour for physical and mental health issues was examined using the international Quality and Cost of Primary Care (QUALICOPC) survey that was conducted in 2013 in Canada. This study used the cross-sectional Patient Experiences Survey collected from 7260 patients in 759 practices across 10 Canadian provinces as part of the QUALICOPC study. A Responsive Care Scale (RCS) was constructed to reflect the degree of health care-seeking behaviour across 11 health conditions. Using several patient characteristics as independent variables, four multiple regression analyses were conducted. Patients' self-reports indicated that there were gender differences in health care-seeking behaviour, with women reporting they visited their primary care provider to a greater extent than did men for both physical and mental health concerns. Overall, patients were less likely to seek care for mental health concerns in comparison to physical health concerns. For both women and men, the results of the regressions indicated that age, illness prevention, trust in physicians and chronic conditions were important factors when explaining health care-seeking behaviours for mental health concerns. This study confirms the gender differences in health care-seeking behaviour advances previous research by exploring in detail the variables predicting differences in health care-seeking behaviour for men and women. The variables were better predictors of health care-seeking behaviour in response to mental health concerns than physical health concerns, likely reflecting greater variation among those seeking mental health care. This study has implications for those working to improve barriers to health care access by identifying those more likely to engage in health care-seeking behaviours and the variables predicting health care-seeking. Consequently, those who are not accessing primary care can be targeted and policies can be developed and put in place to promote their

    Full Text Available Abstract Background Reproductive tract infections (RTI's are endemic in developing countries and entail a heavy toll on women. If untreated, RTI's can lead to adverse health outcomes such as infertility, ectopic pregnancy and increased vulnerability to transmission of the human immunodeficiency virus. It is also associated with adverse pregnancy outcomes. While RTI's and its sequelae abound in Nigeria, there is paucity of publications on the subject in the country. This study assessed the understandings and care seeking behavior with regards to RTI's among women of reproductive age in Lagos, Nigeria with the aim of improving awareness on the subject. Methods A descriptive cross sectional survey of women attending the gynaecological outpatient and family planning clinics of the Lagos State University Teaching Hospital was carried out between 1st June 2008 and 31st August 2008 using a pre-tested questionnaire. Data was analysed using the Epi-Info 3.5 statistical software of the Centre for Disease Control and Prevention, Atlanta U.S.A. Results Most of the respondents (77.2% had heard of RTI's. Toilet was the most perceived mode of contracting RTI's (44.6%, followed by sexual intercourse and poor hygiene. Vaginal discharge was the commonest symptom of RTI's named while inability to get pregnant was the commonest named complication. Majority of the respondent's demonstrated poor overall knowledge of symptoms and complications of RTI"s. 37.4% of the respondents had experienced symptoms of RTI's in the preceding six months. Vaginal discharge was the commonest symptom reported (21.8% and the majority of those who reported symptoms sought medical treatment. Government health centres were the most visited health facilities for treatment. Conclusion Even though most of the respondents have heard of RTI's and sought treatment when symptomatic, they demonstrated poor overall understanding of the subject. There is need to educate women on preventive

    Where access to facilities for childhood diarrhea and pneumonia is inadequate, community case management (CCM) is an effective way of improving access to care. In Pakistan, utilization of CCM for these diseases through the Lady Health Worker Program remains low. Challenges of access to facilities persist leading to delayed care and poor outcomes. Estimating caregiver knowledge, understanding their perceptions and practices, and recognizing how these are related to care seeking decisions about childhood diarrhea and pneumonia is crucial to bring about coherence between supply and demand-side practices. Data was collected from family caregivers to explore their knowledge, perceptions and practices regarding childhood diarrhea and pneumonia. Data from a household survey with 7025 caregivers, seven focus group discussion (FGDs), seven in-depth interviews (IDIs), and 20 detailed narrative interviews are used to explore caregiver knowledge, perceptions and practices. Household survey shows that most family caregivers recognize main signs and symptoms of diarrhea such as loose stools (76%). Fewer recognize signs and symptoms of pneumonia such as breathing problems (21%). Few caregivers (18%) have confidence in lady health workers' (LHWs) ability to treat childhood diarrhea and pneumonia. Care seeking from LHWs remains negligible (financial constraints, and low utilization of community based LHW services. Caregivers do not seek care from LHWs because of lack of trust and LHWs' inability to provide medicines. If finances allow, private doctors, who caregivers perceive as more responsive, are preferred over public sector doctors. Financial resources, availability of time, support for household chores by family and community determine whether, when, and from whom caregivers seek care. Many children do not receive recommended diarrhea and pneumonia treatment on time. Taking into consideration caregiver concerns, adequate supply of medicines to LHWs, improved facility level

    Full Text Available Abstract Background The focus of India’s National Malaria Programme witnessed a paradigm shift recently from health facility to community-based approaches. The current thrust is on diagnosing and treating malaria by community health workers and prevention through free provision of long-lasting insecticidal nets. However, appropriate community awareness and practice are inevitable for the effectiveness of such efforts. In this context, the study assessed community perceptions and practice on malaria and similar febrile illnesses. This evidence base is intended to direct the roll-out of the new strategies and improve community acceptance and utilization of services. Methods A qualitative study involving 26 focus group discussions and 40 key informant interviews was conducted in two districts of Odisha State in India. The key points of discussion were centred on community perceptions and practice regarding malaria prevention and treatment. Thematic analysis of data was performed. Results The 272 respondents consisted of 50% females, three-quarter scheduled tribe community and 30% students. A half of them were literates. Malaria was reported to be the most common disease in their settings with multiple modes of transmission by the FGD participants. Adoption of prevention methods was seasonal with perceived mosquito density. The reported use of bed nets was low and the utilization was determined by seasonality, affordability, intoxication and alternate uses of nets. Although respondents were aware of malaria-related symptoms, care-seeking from traditional healers and unqualified providers was prevalent. The respondents expressed lack of trust in the community health workers due to frequent drug stock-outs. The major determinants of health care seeking were socio-cultural beliefs, age, gender, faith in the service provider, proximity, poverty, and perceived effectiveness of available services. Conclusion Apart from the socio-cultural and behavioural

    The concept of facial emotion recognition is well established in various neuropsychiatric disorders. Although emotional disturbances are strongly associated with somatoform disorders, there are a restricted number of studies that have investigated facial emotion recognition in somatoform disorders. Furthermore, there have been no studies that have regarded this issue using the new diagnostic criteria for somatoform disorders as somatic symptoms and related disorders (SSD). In this study, we aimed to compare the factors of facial emotion recognition between patients with SSD and age- and sex-matched healthy controls (HC) and to retest and investigate the factors of facial emotion recognition using the new criteria for SSD. After applying the inclusion and exclusion criteria, 54 patients who were diagnosed with SSD according to the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) criteria and 46 age- and sex-matched HC were selected to participate in the present study. Facial emotion recognition, alexithymia, and the status of anxiety and depression were compared between the groups. Patients with SSD had significantly decreased scores of facial emotion for fear faces, disgust faces, and neutral faces compared with age- and sex-matched HC (t=-2.88, P=0.005; t=-2.86, P=0.005; and t=-2.56, P=0.009, respectively). After eliminating the effects of alexithymia and depressive and anxious states, the groups were found to be similar in terms of their responses to facial emotion and mean reaction time to facial emotions. Although there have been limited numbers of studies that have examined the recognition of facial emotion in patients with somatoform disorders, our study is the first to investigate facial recognition in patients with SSD diagnosed according to the DSM-5 criteria. Recognition of facial emotion was found to be disturbed in patients with SSD. However, our findings suggest that disturbances in facial recognition were significantly

    Cardiovascular disease was the leading cause of death among women in the United Arab Emirates (UAE) in 2010. Heart attacks usually happen in older women thus symptoms of heart disease may be masked by symptoms of chronic diseases, which could explain the delay in seeking health care and higher mortality following an ischaemic episode among women. This study seeks to a) highlight the awareness of heart diseases among Emirati women and b) to understand Emirati women's health care seeking behaviour in UAE. A cross sectional, descriptive study was conducted using a survey instrument adapted from the American Heart Association National survey. A convenience sample of 676 Emirati women between the ages of 18-55 years completed the questionnaire. The study showed low levels of awareness of heart disease and associated risk factors in Emirati women; only 19.4% participants were found to be aware of heart diseases. Awareness levels were highest in Dubai (OR 2.18, p seeking health care. Interestingly, just 49.1% Emirati women believed that good quality and affordable health care was available in the UAE. Only 28.8% of the participants believed there were sufficient female doctors to respond to health needs of women in UAE. Furthermore, only 36.7% Emirati women chose to be treated in the UAE over treatment in other countries. Emirati women clearly lack the knowledge on severity and vulnerability to heart disease in the region that is essential to improve cardiovascular related health outcomes. This study has identified the need for wider outreach that focuses on gender and age specific awareness on heart disease risks and symptoms. The study has also highlighted potential modifiable barriers in seeking health care that should be overcome to reduce morbidity and mortality due to heart disease among national women of UAE.

    There are currently more people displaced by conflict than at any time since World War II. The profile of displaced populations has evolved with displacement increasingly occurring in urban and middle-income settings. Consequently, an epidemiological shift away from communicable diseases that have historically characterized refugee populations has occurred. The high prevalence of non-communicable diseases (NCDs) poses a challenge to in terms of provision of appropriate secondary and tertiary services, continuity of care, access to medications, and costs. In light of the increasing burden of NCDs faced by refugees, we undertook this study to characterize the prevalence of NCDs and better understand issues related to care-seeking for NCDs among Syrian refugees in non-camp settings in Jordan. A cross-sectional survey of 1550 refugees was conducted using a multi-stage cluster design with probability proportional to size sampling to obtain a nationally representative sample of Syrian refugees outside of camps. To obtain information on chronic conditions, respondents were asked a series of questions about hypertension, cardiovascular disease, diabetes, chronic respiratory disease, and arthritis. Differences by care-seeking for these conditions were examined using chi-square and t-test methods and characteristics of interest were included in the adjusted logistic regression model. Among adults, hypertension prevalence was the highest (9.7%, CI: 8.8-10.6), followed by arthritis (6.8%, CI: 5.9-7.6), diabetes (5.3%, CI: 4.6-6.0), chronic respiratory diseases (3.1%, CI: 2.4-3.8), and cardiovascular disease (3.7%, CI: 3.2, 4.3). Of the 1363 NCD cases, 84.7% (CI: 81.6-87.3) received care in Jordan; of the five NCDs assessed, arthritis cases had the lowest rates of care seeking at 65%, (CI:0-88, p = 0.005). Individuals from households in which the head completed post-secondary and primary education, respectively, had 89% (CI: 22-98) and 88% (CI: 13-98) lower odds of seeking care

    This study explored patterns of abuse and care seeking among women victims of gender-based violence (GBV) in Afghanistan. Individual, semi-structured interviews were conducted with 22 Afghan women (M age = 19 years) living in a shelter for victims of GBV. Interviews were analyzed thematically. Participants reported experiencing multiple forms of abuse. The majority received medical treatment for abuse-related health concerns. However, less than half reported abuse to health care providers or were asked by health care providers about the context of their injuries. Strategies to improve health care responses to GBV are needed to ensure safety and support for Afghan women. © The Author(s) 2015.

    In Nigeria, adolescents are highly vulnerable to sexually transmitted infections (STIs) which have the potential of jeopardising their future reproductive lives if poorly treated. To determine the prevalence and health care seeking behaviour for STIs among secondary school adolescents in Ado, South-Western Nigeria. Male and female adolescents aged 10-19 years. The study employed a descriptive cross-sectional design. A pre-tested, self-administered, semi-structured questionnaire was used to elicit information from 560 adolescents selected from public and private secondary schools in Ado Local Government Area (LGA) of Ekiti State, using a multistage sampling technique. The data were analyzed using descriptive and inferential statistics. Analyzed data were presented in the form of tables and charts. Two hundred and fifty-one (47.1%) respondents had previous symptoms of STIs. The commonest symptoms among the males were penile discharge (30.5%), painful micturition (30.5%) and stomach pain with swollen testes (25.4%). The commonest symptoms among the females were genital itching (27.6%), genital sores (14.1%) and painful micturition (13.1%). Only 26.7% sought treatment from a health facility; 37.0% did nothing; 15.9% went to patent medicine stores, 10.0% used herbs; the rest did self-medication or prayed. The prevalence of STI symptoms among adolescents in Ado-Ekiti is high but their health care seeking behaviour is poor. Health education about the dangers of untreated STI and the importance of seeking treatment early, targeted at adolescents, should be intensified.

    Delirium is underrecognized by nurses, including those working in palliative care settings where the syndrome occurs frequently. Identifying contextual factors that support and/or hinder palliative care nurses' delirium recognition and assessment capabilities is crucial, to inform development of clinical practice and systems aimed at improving patients' delirium outcomes. The aim of the study was to identify nurses' perceptions of the barriers and enablers to recognizing and assessing delirium symptoms in palliative care inpatient settings. A series of semistructured interviews, guided by critical incident technique, were conducted with nurses working in Australian palliative care inpatient settings. A hypoactive delirium vignette prompted participants' recall of delirium and identification of the perceived factors (barriers and enablers) that impacted on their delirium recognition and assessment capabilities. Thematic content analysis was used to analyze the qualitative data. Thirty participants from nine palliative care services provided insights into the barriers and enablers of delirium recognition and assessment in the inpatient setting that were categorized as patient and family, health professional, and system level factors. Analysis revealed five themes, each reflecting both identified barriers and current and/or potential enablers: 1) value in listening to patients and engaging families, 2) assessment is integrated with care delivery, 3) respecting and integrating nurses' observations, 4) addressing nurses' delirium knowledge needs, and 5) integrating delirium recognition and assessment processes. Supporting the development of palliative care nursing delirium recognition and assessment practice requires attending to a range of barriers and enablers at the patient and family, health professional, and system levels.

    This study examined the factors affecting a women's initial intimate partner violence (IPV)-specific health care seeking event which refers to the first health care seeking as a result of IPV in a lifetime. Data were collected using the Life History Calendar method in the Tokyo metropolitan area from 101 women who had experienced IPV. Discrete-time survival analysis was used to assess the time to initial IPV-specific health care seeking. IPV-related injury was the most significant factor associated with increased likelihood of seeking IPV-specific health care seeking for the first time. In the presence of a strong effect of formal help seeking, physical and sexual IPV were no longer significantly related to initial IPV-specific health care seeking. The results suggest some victims of IPV may not seek health care unless they get injured. The timing of receiving health care would be important to ensure the health and safety of victims. © The Author(s) 2014.

    The aim of this study was to explore possible differences in health care seeking behaviour among a rural and urban African population. A cross sectional design was followed using the infrastructure of the PURE-SA study. Four rural and urban Setswana communities which represented different strata of urbanisation in the North West Province, South Africa, were selected. Structured interviews were held with 206 participants. Data on general demographic and socio-economic characteristics, health status, beliefs about health and (access to) health care was collected. The results clearly illustrated differences in socio-economic characteristics, health status, beliefs about health, and health care utilisation. In general, inhabitants of urban communities rated their health significantly better than rural participants. Although most urban and rural participants consider their access to health care as sufficient, they still experienced difficulties in receiving the requested care. The difference in employment rate between urban and rural communities in this study indicated that participants of urban communities were more likely to be employed. Consequently, participants from rural communities had a significantly lower available weekly budget, not only for health care itself, but also for transport to the health care facility. Urban participants were more than 5 times more likely to prefer a medical doctor in private practice (OR:5.29, 95% CI 2.83-988). Recommendations are formulated for infrastructure investments in rural communities, quality of health care and its perception, improvement of household socio-economical status and further research on the consequences of delay in health care seeking behaviour.

    Delirium is prevalent in palliative care inpatient settings and management is often challenging. Despite nurses' integral patient care role, little is known about palliative care nurses' capacity to recognise, assess and respond to patients' delirium symptoms. To explore the experiences, views and practices of inpatient palliative care nurses in delirium recognition and assessment. 30 nurses from nine Australian specialist palliative care inpatient services. Critical incident technique (CIT) guided a series of semi-structured interviews. Prior to interviews participants were given a vignette of a palliative care inpatient with an unrecognised hypoactive delirium, to prompt their recollection and recounting of a similar clinical incident. Clearly recalled and described incidents were analysed using thematic content analysis. 20 of 30 participants recalled and described 28 relevant delirium incidents. Two themes and six sub-themes provide a general description of participants' experiences, views and practice in delirium recognition and assessment. Participants experience distress related to caring for patients with delirium and express compassion and empathy for delirious patients. Enhancing their delirium knowledge, strengthening collaborative multidisciplinary team relationships and better communication are important supports. Some participants, usually those in advance practice roles, describe more comprehensive assessment capabilities that incorporate clinical expertise with whole person awareness, yet systematic and structured delirium screening and assessment processes and application of the delirium diagnosis criteria are largely missing. Use of ambiguous terminology to describe delirium symptoms contributes to ineffective practice. The findings of this study expands our understanding of how palliative care nurses' capacity to recognise and assess patients' delirium symptoms in the inpatient setting could be strengthened.

    Since 2013 the number of suspected adverse reactions to the quadrivalent human papillomavirus (HPV) vaccine reported to the Danish Medicines Agency (DMA) has increased. Due to the resulting public concerns about vaccine safety, the coverage of HPV vaccinations in the childhood vaccination programme has declined. The aim of the present study was to determine health care-seeking prior to the first HPV vaccination among females who suspected adverse reactions to HPV vaccine. In this registry-based case-control study, we included as cases vaccinated females with reports to the DMA of suspected severe adverse reactions. We selected controls without reports of adverse reactions from the Danish vaccination registry and matched by year of vaccination, age of vaccination, and municipality, and obtained from the Danish National Patient Registry and The National Health Insurance Service Register the history of health care usage two years prior to the first vaccine. We analysed the data by logistic regression while adjusting for the matching variables. The study included 316 cases who received first HPV vaccine between 2006 and 2014. Age range of cases was 11 to 52 years, with a peak at 12 years, corresponding to the recommended age at vaccination, and another peak at 19 to 28 years, corresponding to a catch-up programme targeting young women. Compared with 163,910 controls, cases had increased care-seeking in the two years before receiving the first HPV vaccine. A multivariable model showed higher use of telephone/email consultations (OR 1.9; 95% CI 1.2-3.2), physiotherapy (OR 2.1; 95% CI 1.6-2.8) and psychologist/psychiatrist (OR 1.9; 95% CI 1.3-2.7). Cases were more likely to have a diagnosis in the ICD-10 chapters of diseases of the digestive system (OR 1.6; 95% CI 1.0-2.4), of the musculoskeletal system (OR 1.6; 95% CI 1.1-2.2), symptoms or signs not classified elsewhere (OR 1.8; 95% CI 1.3-2.5) as well as injuries (OR 1.5; 95% CI 1.2-1.9).

    Hermanto, Nicola; Zuroff, David Charles

    2016-01-01

    The aim of this study was to test social mentality theory, which views self-compassion/reassurance as a form of intrapersonal relating in which the interpersonal mentalities of care-seeking and caregiving are activated. Self-report measures of motivations, cognitions, and behaviors related to seeking and receiving care from others were administered to 195 students. Self-compassion/reassurance was predicted by the interaction of care-seeking and caregiving, with the positive effect of care-seeking intensified at high caregiving. As hypothesized, the combination of high care-seeking and high caregiving predicted the highest level of self-compassion/reassurance. The lowest level of self-compassion/reassurance was predicted by the combination of low care-seeking and high caregiving consistent with the concept of compulsive caregiving. Findings suggest that fostering a kinder way of relating to oneself may be achieved through more effective care-seeking and caregiving with others.

    Full Text Available This paper examined care-seeking behaviour and its associated risk factors when a family member had diarrhoea. Data was obtained from a survey conducted in Chikwawa, a district in Southern Malawi. Chikwawa is faced with a number of environmental and socioeconomic problems and currently diarrhoea morbidity in the district is estimated at 24.4%, statistically higher than the national average of 17%. Using hierarchically built data from a survey of 1403 households nested within 33 communities, a series of two level binary logistic regression models with Bayesian estimation were used to determine predictors of care-seeking behaviour. The results show that 68% of mothers used oral rehydration solutions (ORS the last time a child in their family had diarrhoea. However, when asked on the action they take when a member of their household has diarrhoea two thirds of the mothers said they visit a health facility. Most respondents (73% mentioned distance and transport costs as the main obstacles to accessing their nearest health facility and the same proportion of respondents mentioned prolonged waiting time and absence of health workers as the main obstacles encountered at the health facilities. The main predictor variables when a member of the family had diarrhoea were maternal age, distance to the nearest health facility, school level, and relative wealth, household diarrhoea endemicity, and household size while the main predictor variables when a child had diarrhoea were existence of a village health committee (VHC, distance to the nearest health facility, and maternal age. Most households use ORS for the treatment of diarrhoea and village health committees and health surveillance assistants (HSAs are important factors in this choice of treatment. Health education messages on the use and efficacy of ORS to ensure proper and prescribed handling are important. There is need for a comprehensive concept addressing several dimensions of management and

    Full Text Available We start from the idea that occupational therapy client/patient struggles to run their daily life for many and varied reasons. Illness may be one of many different reasons leading subjects to experience restriction in daily activities or a daily routine merely related to the treatment, resulting from the loss of self-control in the world brought about by the new established situation. This paper presents a clinical case of a young woman with a diagnostic hypothesis of bipolar affective disorder and discusses how the non-recognition and unfamiliarity with the new contour arising from the illness open space for occupational therapy care. Moreover, we try to elucidate elements of clinical reasoning and procedures used by a student of occupational therapy during his fieldwork education on mental health. Our reflections are based on the Dynamics Occupational Therapy Method (DOTM whose proposal is to extend health spaces into the client/patient’s life so as to build/expand their daily life activities, based on the analysis of the triadic relationship dynamic (occupational therapist, subject and activities. This experience report is composed by the situational diagnosis of the case, the development of the therapeutic process and the reflections and analysis that the case raised during the fieldwork experience in occupational therapy in mental health.

    This study provides a comprehensive review of the care-seeking patterns and direct economic burden of injuries from the victims' perspective in rural Bangladesh using a 2013 household survey covering 1.17 million people. Descriptive statistics and bivariate analyses were used to derive rates and test the association between variables. An analytic model was used to estimate total injury out-of-pocket (OOP) payments and a multivariate probit regression model assessed the relationship between financial distress and injury type. Results show non-fatal injuries occur to 1 in 5 people in our sample per year. With average household size of 4.5 in Bangladesh--every household has an injury every year. Most non-fatally injured patients sought healthcare from drug sellers. Less than half of fatal injuries sought healthcare and half of those with care were hospitalized. Average OOP payments varied significantly (range: $8-$830) by injury type and outcome (fatal vs. non-fatal). Total injury OOP expenditure was $$355,795 and $5000 for non-fatal and fatal injuries, respectively, per 100,000 people. The majority of household heads with injuries reported financial distress. This study can inform injury prevention advocates on disparities in healthcare usage, OOP costs and financial distress. Reallocation of resources to the most at risk populations can accelerate reduction of preventable injuries and prevent injury related catastrophic payments and impoverishment.

    Full Text Available Cerebral malaria is a significant cause of childhood morbidity in our region. The challenges of effective management include time and quality of treatment. The study appraised the health care seeking behavior of caregivers of sick children who developed cerebral malaria, in Zaria, northwestern Nigeria. Caregivers indentified were parents 29 (87.9% and grandparents 4 (12.1%. Most of them were in the upper social classes. Health care options utilized before presentation at our facility were formal health facility 24 (72.7%, patent medicine seller 12 (36.4%, home treatment 10 (30.3%, and herbal concoction 6 (18.2% with majority 24 (72.7% using more than one option. Antimalarial therapy was instituted in 25 (75.6% of the cases. Mortality was significantly associated with the use of herbal concoction, treatment at a formal health facility and patent medicine seller, multiple convulsions, age less than 5 years, and noninstitution of antimalarial therapy before presentation. The study showed use of inappropriate health care options by caregivers and highlighted the need to pursue an awareness drive among caregivers on the use of health care options.

    Health effects and health care seeking were investigated among women in rural Vietnam exposed to physical and/or sexual violence from their partner in the past year. The study was conducted within the framework of the demographic surveillance site in Bavi District, Ha Tay Province in northern Vietnam. Face-to-face interviews based on a questionnaire developed by the WHO for use in violence research were conducted with 883 randomly selected women. Past-year violence and health effects were investigated in bi and multivariate analyses. The prevalence of past-year physical and/or sexual violence was 9.2% (n = 81). Women exposed to violence ran a considerably elevated risk of memory loss (OR 3.7; 1.8-7.5), pain or discomfort (OR 3.8; 2.3-6.3), sadness or depression (OR 4.5; 2.7-7.5) and having suicidal thoughts (OR 2.8; 1.04-7.3) compared with those with no violence experience in the past year, when adjusted for socio-demographic factors. Almost 50% (n = 40) of the women exposed to violence reported injuries and, of those, 58% had to seek health care. Physical and/or sexual violence are common occurrences in Vietnam, associated with pain, injuries and mental health problems in exposed women. These results point to the need for a reliable health surveillance system, along with health care and support activities for victimised women, and policy initiatives to prevent this violence.

    Health-care seeking behaviour is important as it determines acceptance of health care and outcomes of chronic conditions but it has been investigated to a limited extent among persons with diabetes in developing countries. The aim of the study was to explore health-care seeking behaviour among persons with type 2 diabetes to understand reasons for using therapies offered by traditional healers. Descriptive study using focus-group interviews. Three purposive focus-groups were conducted in 2011 of 10 women and 7 men aged 39-72 years in Uganda. Data were collected through semi-structured interviews and qualitatively analysed according to a method described for focus-groups. Reasons for seeking help from traditional healers were symptoms related to diabetes such as polydipsia, fatigue and decreased sensitivity in lower limbs. Failure of effect from western medicine was also reported. Treatment was described to be unknown extracts, of locally made products taken as herbs or food, and participants had sought help from different health facilities with the help of relatives and friends. The pattern of seeking care was inconsistent, with a switch between different health care providers under the influence of the popular and folk sectors. Despite beliefs in using different healthcare providers seeking complementary and alternative medicine, participants still experienced many physical health problems related to diabetes complications. Health professionals need to be aware of the risk of switches between different health care providers, and develop strategies to initiate health promotion interventions to include in the care actors of significance to the patient from the popular, folk and professional sectors, to maintain continuity of effective diabetes care.

    Malaria remains a major cause of morbidity and mortality in children under 5 years of age in Equatorial Guinea. Early appropriate treatment can reduce progression of the illness to severe stages, thus reducing of mortality, morbidity and onward transmission. The factors that contribute to malaria treatment delay have not been studied previously in Equatorial Guinea. The objective of this study was to assess the determinants of delay in seeking malaria treatment for children in the Bata district, in mainland Equatorial Guinea. A cross-sectional study was conducted in Bata district, in 2013, which involved 428 houses in 18 rural villages and 26 urban neighbourhoods. Household caregivers were identified in each house and asked about their knowledge of malaria and about the management of the last reported malaria episode in a child 15 years and younger under their care. Bivariate and multivariate statistical analyses were conducted to determine the relevance of socio-economic, geographical and behavioural factors on delays in care-seeking behaviour. Nearly half of the children sought treatment at least 24 h after the onset of the symptoms. The median delay in seeking care was 2.8 days. Children from households with the highest socio-economic status were less likely to be delayed in seeking care than those from households with the lowest socio-economic status (OR 0.37, 95% CI 0.19-0.72). Children that first received treatment at home, mainly paracetamol, were more than twice more likely to be delayed for seeking care, than children who did not first receive treatment at home (OR 2.36, 95% CI 1.45-3.83). Children living in a distance >3 km from the nearest health facility were almost two times more likely to be delayed in seeking care than those living closer to a facility but with non significant association once adjusted for other variables (OR 1.75, 95% CI 0.88-3.47). To decrease malaria morbidity and mortality in Bata district, efforts should be addressed to reduce

    In Nigeria, women too often suffer the consequences of serious obstetric complications that may lead to death. Delay in seeking care (phase I delay) is a recognized contributor to adverse pregnancy outcomes. This qualitative study aimed to describe the health care seeking practices in pregnancy, as well as the socio-cultural factors that influence these actions. The study was conducted in Ogun State, in south-western Nigeria. Data were collected through focus group discussions with pregnant women, recently pregnant mothers, male decision-makers, opinion leaders, traditional birth attendants, health workers, and health administrators. A thematic analysis approach was used with QSR NVivo version 10. Findings show that women utilized multiple care givers during pregnancy, with a preference for traditional providers. There was a strong sense of trust in traditional medicine, particularly that provided by traditional birth attendants who are long-term residents in the community. The patriarchal c influenced health-seeking behaviour in pregnancy. Economic factors contributed to the delay in access to appropriate services. There was a consistent concern regarding the cost barrier in accessing health services. The challenges of accessing services were well recognised and these were greater when referral was to a higher level of care which in most cases attracted unaffordable costs. While the high cost of care is a deterrent to health seeking behaviour, the cost of death of a woman or a child to the family and community is immeasurable. The use of innovative mechanisms for health care financing may be beneficial for women in these communities to reduce the barrier of high cost services. To reduce maternal deaths all stakeholders must be engaged in the process including policy makers, opinion leaders, health care consumers and providers. Underlying socio-cultural factors, such as structure of patriarchy, must also be addressed to sustainably improve maternal health. NCT

    People working in Ghana's informal sector have low rates of enrolment in the publicly funded National Health Insurance Scheme. Informal sector workers, including migrant girls and women from northern Ghana working as head porters (kayayei), report challenges obtaining insurance and seeking formal health care. This article analyses how health insurance status affects kayayei migrants' care-seeking behaviours. This mixed-methods study involved surveying 625 migrants using respondent-driven sampling and conducting in-depth interviews with a sub-sample of 48 migrants. Analyses explore health status and health seeking behaviours for recent illness/injury. Binary logistic regression modelled the effects of selected independent variables on whether or not a recently ill/injured participant (n = 239) sought health care. Although recently ill/injured participants (38.4%) desired health care, less than half (43.5%) sought care. Financial barriers overwhelmingly limit kayayei migrants from seeking health care, preventing them from registering with the National Health Insurance Scheme, renewing their expired health insurance policies, or taking time away from work. Both insured and uninsured migrants did not seek formal health services due to the unpredictable nature of out-of-pocket expenses. Catastrophic and impoverishing medical expenses also drove participants' migration in search of work to repay loans and hospital bills. Health insurance can help minimize these expenditures, but only 17.4% of currently insured participants (58.2%) reported holding a valid health insurance card in Accra. The others lost their cards or forgot them when migrating. Access to formal health care in Accra remains largely inaccessible to kayayei migrants who suffer from greater illness/injury than the general female population in Accra and who are hindered in their ability to receive insurance exemptions. With internal migration on the rise in many settings, health systems must recognize the

    It is widely held that decisions whether or when to attend health facilities for childbirth are not only influenced by risk awareness and household wealth, but also by factors such as autonomy or a woman’s ability to act upon her own preferences. How autonomy should be constructed and measured – namely, as an individual or cluster-level variable – has been less examined. We drew on household survey data from Zambia to study the effect of several autonomy dimensions (financial, relationship, freedom of movement, health care seeking and violence) on place of delivery for 3200 births across 203 rural clusters (villages). In multilevel logistic regression, two autonomy dimensions (relationship and health care seeking) were strongly associated with facility delivery when measured at the cluster level (OR 1.27 and 1.57, respectively), though not at the individual level. This suggests that power relations and gender norms at the community level may override an individual woman’s autonomy, and cluster-level measurement may prove critical to understanding the interplay between autonomy and care seeking in this and similar contexts.

    Health problems among travelers in developing countries are not uncommon. Little is known about the occurrence of health problems and their impacts among backpackers in Thailand. The objective of this study was to assess the health problems and the health seeking behavior among adult backpackers who visited Thailand. This was a cross-sectional questionnaire-based study. Data were collected from foreign adult backpackers in Khao San Road, Bangkok. They were asked about their demographic data, health problems (if any), and health-care seeking behavior if they became ill. During May to July 2015, 420 backpackers were enrolled in this study. Of these, 51.4 % were male with a median age of 26.4 years. Up to 66.9 % were of European origin, while 17.4 % were North American. Fifty-eight percent sought pre-travel consultation before traveling. In this study, 10.2 % (43/420) of the participants reported at least health problem during travel. Most of them (79.1 %) had single episode of illness. Of this, diarrhea was the most common health problem (30.4 %), followed by abdominal pain (14.3 %), skin problems (8.9 %), respiratory problems (8.9 %), accident-associated injury (7.1 %), and febrile illness (7.1 %). One third of backpackers with health problems spontaneously recovered without any treatment, while nearly a quarter treated themselves with standby medication, and one in five had to buy over the counter medication. Just over 9 % of backpackers with a health problem sought medical care at a hospital. Among travellers with health problems, 72.1 % reported that their health problems did not significantly impact to their trip, while 23.3 % had to delay or postpone their trip for at least 1 day, and 4.7 % had to cancel some trip and/or activity. Longer duration of stay was significantly related to higher occurrence of health problems while traveling. Approximately 10 % of adult backpackers experienced some health problems during their trip in Thailand

    Full Text Available The burden of maternal complications during antepartum and intrapartum periods is high and care seeking from a trained provider is low, particularly in low middle income countries of sub-Saharan Africa and South Asia. Identification of barriers to access to trained care and development of strategies to address them will contribute to improvements in maternal health. Using data from a community-based cohort of pregnant women, this study identified the prevalence of antepartum and intrapartum complications and determinants of care-seeking for these complications in rural Bangladesh.The study was conducted in 24,274 pregnant women between June 2011 and December 2013 in rural Sylhet district of Bangladesh. Women were interviewed during pregnancy to collect data on demographic and socioeconomic characteristics; prior miscarriages, stillbirths, live births, and neonatal deaths; as well as data on their ability to make decision to go to health center alone. They were interviewed within the first 7 days of child birth to collect data on self-reported antepartum and intrapartum complications and care seeking for those complications. Bivariate analysis was conducted to explore association between predisposing (socio-demographic, enabling (economic, perceived need, and service related factors with care-seeking for self-reported antepartum and intrapartum complications. Multivariable multinomial logistic regression was performed to examine the association of selected factors with care-seeking for self-reported antepartum and intrapartum complications adjusting for co-variates.Self-reported antepartum and intrapartum complications among women were 14.8% and 20.9% respectively. Among women with any antepartum complication, 58.9% sought care and of these 46.5% received care from a trained provider. Of the women with intrapartum complications, 61.4% sought care and of them 46.5% did so from a trained provider. Care-seeking for both antepartum and intrapartum

    We have developed a new paradigm that targets the recognition of facial expression of emotions. Here we report the protocol of a randomised controlled trial of the effects of emotion recognition training on mood in a sample of individuals with depressive symptoms over a 6-week follow-up period. We will recruit 190 adults from the general population who report high levels of depressive symptoms (defined as a score ≥ 14 on the Beck Depression Inventory-II). Participants will attend a screening session and will be randomised to intervention or control procedures, repeated five times over consecutive days (Monday to Friday). A follow-up session will take place at end-of -treatment, 2-weeks and 6-weeks after training. Our primary study outcome will be depressive symptoms, Beck Depression Inventory- II (rated over the past two weeks). Our secondary outcomes are: depressive symptoms, Hamilton Rating Scale for Depression; anxiety symptoms, Beck Anxiety Inventory (rated over the past month); positive affect, Positive and Negative Affect Schedule (rated as 'how you feel right now'); negative affect, Positive and Negative Affect Schedule (rated as 'how you feel right now'); emotion sensitivity, Emotion Recognition Task (test phase); approach motivation and persistence, the Fishing Game; and depressive interpretation bias, Scrambled Sentences Test. This study is of a novel cognitive bias modification technique that targets biases in emotional processing characteristic of depression, and can be delivered automatically via computer, Internet or Smartphone. It therefore has potential to be a valuable cost-effective adjunctive treatment for depression which may be used together with more traditional psychotherapy, cognitive-behavioural therapy and pharmacotherapy.

    Full Text Available Aim: We investigated the attitude of pets or livestock owning households in a university community to animal health care services and assessed the knowledge and awareness level of the residents on zoonoses. Materials and Methods: Structured questionnaire was used to obtain information on demography, pet or livestock ownership, animal health care seeking behavior, awareness and knowledge of zoonoses from 246 households. We did descriptive statistics and bivariate analysis to determine the level of association in discrete variables between owners and non-owners of pets or livestock at a significant level of p<0.05. Results: Of the 246 respondents, 80 (32.5% were either pet or livestock owners. The animal health care seeking behavior of the 80 pets or livestock owners in terms of treatment and vaccination was 70%. Of the 56 (70% who provided health care services for their animals, about 48 (85.7% engaged the services of a veterinarian. Dog owning households (42 had the highest frequency of treating their pets against endoparasites (97.6%; ectoparasites (81% and vaccination against diseases (73.8%. Of the 246 respondents, only 47 (19.1% have heard of the term zoonoses. Of the considered zoonoses; their awareness of rabies (79.3% was the highest, followed by Lassa fever (66.3%, the least was pasteurellosis with 18.7%. Having pets or livestock was significantly associated (p=0.04 with rabies awareness. However, there is no significant difference in the level of awareness of zoonoses; knowledge of zoonoses, knowledge of prevention of zoonoses and knowledge of risk of zoonoses between owners and non-owners of pets or livestock. Conclusion: The animal health care seeking behavior of households with pets or livestock is good and should be encouraged. Public education should be created for other zoonoses aside from rabies, Lassa fever, and avian influenza.

    Many pregnant women in resource-poor countries seek care only after developing severe complications during childbirth at home and often reach health facilities in moribund conditions. The objectives were to (i) investigate the association between care-seeking duration and fetal survival at admission; and (ii) assess the significance of care-seeking duration in relation to other determinants. Data were analysed for 266 women who were pregnant with a singleton and admitted in life-threatening conditions to the maternity ward of Herat Regional Hospital in Afghanistan from February 2007 to January 2008. Information about the women's care-seeking durations, social and financial resources, reproductive factors, household economic status and household types were collected during interviews with the women and their husbands. Information about fetal heartbeats at admission was extracted from the women's medical records. Fifty-four per cent of the women had a decision delay lasting 3 h or more; 69% had a transport delay lasting 3 h or more. Multivariable logistic regression analyses suggest that a decision delay lasting an hour or more increased the odds of fetal death by 6.6 (95% confidence interval [CI] 1.6, 26.3) compared with a delay less than 1 h. A woman's lack of financial autonomy and a distance from her natal home increased the odds of fetal death by 3.1 [95% CI 1.1, 8.4] and 2.5 [95% CI 1.0, 6.3] respectively. An integrated approach to improving fetal and maternal health from pre-pregnancy through childbirth (including increasing women's social and financial resources) is crucial particularly where senior family members act as gatekeepers to women's access to health care. © 2012 Blackwell Publishing Ltd.

We carried out a survey to study patient demographics, symptom prevalence, healthcare-seeking behavior, and patient satisfaction with available treatment options in women with chronic constipation.Methods: Responses were collected predominantly via a web-based survey from a panel representative of Singapore's women population. Eligibility was established using a nine-question screener.Results: A total of 1006 invited females took part in an online screener survey, of which 911 respondents did not meet the eligibility requirements for the chronic constipation survey. Of the total panelists consenting to participate (via both online and face-to-face interviews, 100 women met eligibility requirements and took the 22-question survey. Eligible respondents were skewed to younger patients but well mixed in terms of marital status. The majority of them were not keen on doing exercise and were working women, especially white collar females. The majority complained of straining and hard stools as the most common constipation symptoms (88% and 80% respectively and rated constipation symptoms as severe or moderate. On average, respondents experienced constipation symptoms for 6 to 7 months in the last year. In more than two-thirds of respondents, constipation symptoms were frequent (at least 1 in 3 times. Most of the patients had attempted to treat constipation themselves and 80% had tried laxatives before visiting the doctor. Satisfaction with fiber supplements and laxatives was average and many of the users were not satisfied with their effect. Ineffectiveness and prolonged time taken for the treatment to take effect were the most common reasons for dissatisfaction. Nearly all respondents

    The purpose of this study is to characterize the relationship between identity and health care experiences (including antiretroviral therapy utilization) among HIV-positive sexual minority males. This qualitative study used grounded theory with data collection occurring through focus groups and interviews. A questionnaire was used to complete a demographic profile. The study included 47 HIV positive participants from three minorities: gay men, bisexual men and transgendered persons, gender identifying as female and or living as women. Sessions elicited information on: (1) general experiences with health care, (2) experiences with HIV antiretroviral therapies and issues surrounding access, and (3) adherence to these therapies and identity in relation to health care. These textual data revealed three themes: (1) the importance of sexual identity and its social and cultural context, (2) the differences in the health concerns between the sexual minorities and (3) a wide spectrum of experiences with the health care system that provide information surrounding the access to and adequacy of health care. Successful health care providers are aware of different issues that may play a role in the provision of health care to these sexual minorities. Providers awareness of sexual and social identity and the related different cultural values, beliefs and custom enhance care seeking and therapeutic adherence. For sexual minorities, primary care remains the most important entry point into the health care system. Cultural competence of care providers can foster patient's care seeking and adherence to treatment.

    The purpose of the study was to investigate the consequences of recurrent non-specific low back pain in Zimbabwean adolescents. Recurrent non-specific low back pain is a common cause of adult disability in low-income countries. However, its impact in adolescents has been a matter of debate in the literature. A survey was conducted using a cluster sample of 544 school children between the ages of 13 and 19 years. The school children were randomly selected from government-administered secondary schools in Harare, Zimbabwe. Parental and students' response rate were 90.3 and 97.8 %, respectively. Almost a third (28.8 %) of school children reported recurrent symptoms (CI 27.8-31.6). However, the majority (84 %) of these cases were unknown to parents. Twenty-seven percent reported having sought medical treatment. On the nine-item Hanover Low Back Pain Disability Questionnaire, 71.2 % of school children had at least one activity of daily living compromised by recurrent NSLBP, especially sports participation. However, severe disability was reported in 28 % of the adolescents. Health-care seeking behaviour was not associated with the level of disability [χ (2)(1) = 0.36, p = 0.55]. Although most parents are unaware, recurrent NSLBP is common in Zimbabwean school children. However, treatment is rarely sought for the symptoms. A preponderance of adolescents with recurrent NSLBP experiences some degree of functional consequences, although severe disability is rare. There is need to raise awareness of the condition in schools and to parents. Spinal health educational programmes may need to be implemented to avert the functional consequences. Further studies are needed in the future to investigate the coping strategies for pain in adolescents.

    Malaria remains one of the leading causes of morbidity and mortality among children under five years old in many low- and middle-income countries. In this study, we examined how malaria-related ideational factors may influence care-seeking behavior among female caregivers of children under five with fever. Data came from population-based surveys conducted in 2014-2015 by U.S. Agency for International Development-funded surveys in Madagascar, Mali, and Nigeria. The outcome of interest was whether a child under five with fever within two weeks prior to the survey was brought to a formal health facility for care. Results show a wide variation in care-seeking practices for children under five with fever across countries. Seeking care for febrile children under five in the formal health sector is far from a norm in the study countries. Important ideational factors associated with care-seeking behavior included caregivers' perceived social norms regarding treatment of fever among children under five in Nigeria and Madagascar, and caregiver's knowledge of the cause of malaria in Mali. Findings indicate that messages aimed to increase malaria-related knowledge should be tailored to the specific country, and that interventions designed to influence social norms about care-seeking are likely to result in increased care-seeking behavior for fever in children under five.

    The aim of this study was to evaluate the impact of distance from residence to treatment center on access to care for female pelvic floor disorders at an academic institution. A retrospective cross-sectional study was conducted of women seen for pelvic floor disorders at an academic institution from 2008 to 2014. Patient characteristics were extracted from charts. Geographical and US census data was obtained from public records and used to calculate distance from patient residence to physician office. Statistical analysis was performed using R Software (Version 0.98.1102) and Microsoft Excel (Version 14.4.7). Statistical significance was defined as a 2-sided P value of less than 0.05, and the χ test was used to determine associations of categorical variables. A total of 3015 patients were included in the analysis. The mean distance traveled was 93 miles. Thirty percent of patients traveled more than 50 miles. Many patients (43%) reported having the symptoms for more than 2 years. Patients who traveled farther were significantly more likely to be white, English-speaking, and with pelvic organ prolapse as primary complaint. These patients were more likely to plan surgery at the first visit than patients who traveled less far (29% vs 14%). Patients who traveled farther were also more likely to live in counties with a low percentage of persons older than 65 years and low percentage of female inhabitants. Women who travel the farthest for treatment of pelvic floor disorders have experienced the symptoms for longer duration and are more willing to plan surgery at presentation. These women also come from counties with fewer elderly women, suggesting future outreach care should focus on similar geographic areas.

    In this study, the influence of culture and discrimination on care-seeking behavior of elderly African Americans was explored. This was a qualitative phenomenological study that involved in-depth interviews with 15 African American men and women aged 60 and older in Alabama. The sample size of 15 was adequate for the phenomenological method of this study. While this was a small exploratory study and was not intended for any generalizations, it did provide a unique opportunity to hear the voices, the concerns, and the stories of elderly African Americans, which have often been overlooked in the literature. The following themes emerged from the analysis of data: (1) perception of health as ability to be active, (2) reluctance toward prescription medicine use, (3) lack of trust in doctors, (4) avoidance of bad news, (5) race of doctors, (6) use of home remedies, and (7) importance of God and spirituality on health, illness, and healing.

    Compared with the traditional ways of gaining health-related information from newspapers, magazines, radio, and television, the Internet is inexpensive, accessible, and conveys diverse opinions. Several studies on how increasing Internet use affected outpatient clinic visits were inconclusive. The objective of this study was to examine the role of Internet use on ambulatory care-seeking behaviors as indicated by the number of outpatient clinic visits after adjusting for confounding variables. We conducted this study using a sample randomly selected from the general population in Taiwan. To handle the missing data, we built a multivariate logistic regression model for propensity score matching using age and sex as the independent variables. The questionnaires with no missing data were then included in a multivariate linear regression model for examining the association between Internet use and outpatient clinic visits. We included a sample of 293 participants who answered the questionnaire with no missing data in the multivariate linear regression model. We found that Internet use was significantly associated with more outpatient clinic visits (P=.04). The participants with chronic diseases tended to make more outpatient clinic visits (PInternet may be associated with patients' increasing need for interpreting and discussing the information with health care professionals, thus resulting in an increasing number of outpatient clinic visits. In addition, the media literacy of Web-based health-related information seekers may also affect their ambulatory care-seeking behaviors, such as outpatient clinic visits. ©Ronan Wenhan Hsieh, Likwang Chen, Tsung-Fu Chen, Jyh-Chong Liang, Tzu-Bin Lin, Yen-Yuan Chen, Chin-Chung Tsai.

    Full Text Available Abstract Background Infections affecting the middle ear are a common childhood occurrence. Some cases may present with ear discharge through a tympanic membrane perforation which may heal spontaneously. However, up to 5% or more cases of those affected have persistent ear discharge. A number of barriers contribute towards delayed presentation at health facilities for treatment of ear infections. We conducted a study to evaluate parents’ and caregivers’ knowledge and care seeking practices for ear infections in children under five in Gasabo district in Kigali, Rwanda. Methods Parents/guardians (n = 810 were interviewed using a structured questionnaire to elicit their knowledge of ear infections in children under five and their attitude to seeking care for their children. Results The mean age of the respondents was 31.27 years (SD = 7.88, range 17–83. Considering an average of knowledge parameters which included causes, symptoms, prevention, treatment and consequences of ear infections, we found that 76.6% (622 of respondents were knowledgeable about ear infections. We defined a positive practice as seeking medical treatment (community health workers or health facility and this was found in 89.1% (722 respondents. Correlating knowledge with choice of seeking treatment, respondents were 33% less likely to practice medical pluralism (OR = 0.33, CI 0.11–0.97, P = 0.043 if they were familiar with infections. Moreover, urban dweller were 1.7 times more likely to know ear infections compared to rural dwellers (OR = 1.70, CI 1.22–2.38, P = 0.002. Conclusion The majority of respondents had good knowledge and positive attitudes and practices about ear infection. However, medical pluralism was common. There is need to improve the community’s awareness and access to primary health care facilities for the care of ear infections especially in rural areas of Rwanda.

    Full Text Available Abstract Background Healthcare-seeking behaviour in patients with diabetes mellitus (DM has been investigated to a limited extent, and not in developing countries. Switches between different health sectors may interrupt glycaemic control, affecting health. The aim of the study was to explore healthcare-seeking behaviour, including use of complementary alternative medicine (CAM and traditional healers, in Ugandans diagnosed with DM. Further, to study whether gender influenced healthcare-seeking behaviour. Methods This is a descriptive study with a snowball sample from a community in Uganda. Semi-structured interviews were held with 16 women and 8 men, aged 25-70. Data were analysed by qualitative content analysis. Results Healthcare was mainly sought among doctors and nurses in the professional sector because of severe symptoms related to DM and/or glycaemic control. Females more often focused on follow-up of DM and chronic pain in joints, while males described fewer problems. Among those who felt that healthcare had failed, most had turned to traditional healers in the folk sector for prescription of herbs or food supplements, more so in women than men. Males more often turned to private for-profit clinics while females more often used free governmental institutions. Conclusions Healthcare was mainly sought from nurses and physicians in the professional sector and females used more free-of-charge governmental institutions. Perceived failure in health care to manage DM or related complications led many, particularly women, to seek alternative treatment from CAM practitioners in the folk sector. Living conditions, including healthcare organisation and gender, seemed to influence healthcare seeking, but further studies are needed.

    Full Text Available Introduction: Health care-seeking behavior of individuals determines how early they present for appropriate care. In patients with chronic kidney disease (CKD, late presentation to the nephrologist is associated with poor outcomes. This study aims to describe the health care-seeking behavior of patients with CKD attending the nephrology outpatient clinic of a teaching hospital located in Lagos, Nigeria. Materials and Methods: This was a cross-sectional survey conducted on 104 consecutive adult patients with CKD, presenting for the first time at the nephrology outpatient clinic of a teaching hospital located in Lagos, South West Nigeria. Information was retrieved from the study participants using a structured interviewer-administered questionnaire, entered into an Excel spreadsheet, and analyzed using Epi Info® statistical software version 7.0. Results: Overall, 74 (71.2% patients sought help, first from a trained health care provider, and their health care-seeking behavior was adjudged to be appropriate. Compared to patients with appropriate health care-seeking behavior, those with inappropriate health care-seeking behavior had a lower mean age (40.4 ± 13.7 years vs 47.3 ± 15.6 years;P = 0.03, were less likely to see their illness as a medical problem (46.7% vs 67.6%;P = 0.04, more likely to have a monthly income less than N25,000 ($150 (80.0% vs 59.5%;P = 0.04, and have received below tertiary level education (20.0% vs 48.6%; P < 0.01. They were also more likely to have consulted more than one health care provider before being referred to our clinic. The factors predicting inappropriate health care-seeking behavior were education below the tertiary level and age less than 45 years. Conclusion: Though health care-seeking behavior was appropriate in majority of our patients with CKD, there remains a need for improved public health awareness.

    Few existing studies have examined health and oral health needs and treatment-seeking behavior among the homeless and injection drug users (IDUs). This paper describes the prevalence and correlates of health and oral health care needs and treatment-seeking behaviors in homeless IDUs recruited in San Francisco, California, from 2003 to 2005 (N = 340). We examined sociodemographic characteristics, drug use patterns, HIV status via oral fluid testing, physical health using the Short Form 12 Physical Component Score, self-reported needs for physical and oral health care, and the self-reported frequency of seeking medical and oral health care. The sample had a lower health status as compared to the general population and reported a frequent need for physical and oral health care. In bivariate analysis, being in methadone treatment was associated with care-seeking behavior. In addition, being enrolled in Medi-Cal, California's state Medicaid program, was associated with greater odds of seeking physical and oral health care. Methamphetamine use was not associated with higher odds of needing oral health care as compared to people who reported using other illicit drugs. Homeless IDUs in San Francisco have a large burden of unmet health and oral health needs. Recent cuts in Medi-Cal's adult dental coverage may result in a greater burden of oral health care which will need to be provided by emergency departments and neighborhood dental clinics.

    Lack of appropriate health care seeking for ill mothers and neonates contributes to high mortality rates. A major challenge is the appropriate mix of strategies for creating demand as well as provision of services. Systematic review and meta-analysis of experimental studies (last search: Jan 2015) to assess the impact of different strategies to improve maternal and neonatal health care seeking in low- and middle-income countries (LMIC). Fifty-eight experimental [randomized controlled trials (RCTs), non-RCTs, and before-after studies] with 310,652 participants met the inclusion criteria. Meta-analyses from 29 RCTs with a range of different interventions (e.g. mobilization, home visitation) indicated significant improvement in health care seeking for neonatal illnesses when compared with standard/no care [risk ratio (RR) 1.40; 95 confidence interval (CI): 1.17-1.68, 9 studies, n=30,572], whereas, no impact was seen on health care seeking for maternal illnesses (RR 1.06; 95% CI: 0.92-1.22, 5 studies, n=15,828). These interventions had a significant impact on reducing stillbirths (RR 0.82; 95% CI: 0.73-0.93, 11 studies, n=176,683), perinatal deaths (RR 0.84; 95% CI: 0.77-0.90, 15 studies, n=279,618), and neonatal mortality (RR 0.80; 95% CI: 0.72-0.89, 20 studies, n=248,848). On GRADE approach, evidence was high quality except for the outcome of maternal health care seeking, which was moderate. Community-based interventions integrating strategies such as home visiting and counseling can help to reduce fetal and neonatal mortality in LMIC.

    The southern California wildfires in autumn 2007 resulted in widespread disruption and one of the largest evacuations in the state's history. This study aims to identify unmet medical needs and health care-seeking patterns as well as prevalence of acute and chronic disease among displaced people following the southern California wildfires. These data can be used to increase the accuracy, and therefore capacity, of the medical response. A team of emergency physicians, nurses, and epidemiologists conducted surveys of heads of households at shelters and local assistance centers in San Diego and Riverside counties for 3 days beginning 10 days postdisaster. All households present in shelters on the day of the survey were interviewed, and at the local assistance centers, a 2-stage sampling method was used that included selecting a sample size proportionate to the number of registered visits to that site compared with all sites followed by a convenience sampling of people who were not actively being aided by local assistance center personnel. The survey covered demographics; needs following the wildfires (shelter, food, water, and health care); acute health symptoms; chronic health conditions; access to health care; and access to prescription medications. Among the 175 households eligible, 161 (92.0%) households participated. Within the 47 households that reported a health care need since evacuation, 13 (27.7%) did not receive care that met their perceived need. Need for prescription medication was reported by 47 (29.2%) households, and 20 (42.6%) of those households did not feel that their need for prescription medication had been met. Mental health needs were reported by 14 (8.7%) households with 7 of these (50.0%) reporting unmet needs. At least 1 family member per household left prescription medication behind during evacuation in 46 households (28.6%), and 1 family member in 48 households (29.8%) saw a health care provider since their evacuation. Most people sought

    Full Text Available Background: Care for women and babies before, during, and after the time of birth is a sensitive measure of the functionality of any health system. Engaging communities in preventing newborn deaths is a promising strategy to achieve further progress in child survival in sub-Saharan Africa. Objective: To assess the effect of a home visit strategy combined with health facility strengthening on uptake of newborn care-seeking, practices and services, and to link the results to national policy and scale-up in Uganda. Design: The Uganda Newborn Study (UNEST was a two-arm cluster-randomised controlled trial in rural eastern Uganda. In intervention villages volunteer community health workers (CHWs were trained to identify pregnant women and make five home visits (two during pregnancy and three in the first week after birth to offer preventive and promotive care and counselling, with extra visits for sick and small newborns to assess and refer. Health facility strengthening was done in all facilities to improve quality of care. Primary outcomes were coverage of key essential newborn care behaviours (breastfeeding, thermal care, and cord care. Analyses were by intention to treat. This study is registered as a clinical trial, number ISRCTN50321130. Results: The intervention significantly improved essential newborn care practices, although many interventions saw major increases in both arms over the study period. Immediate breastfeeding after birth and exclusive breastfeeding were significantly higher in the intervention arm compared to the control arm (72.6% vs. 66.0%; p=0.016 and 81.8% vs. 75.9%, p=0.042, respectively. Skin-to-skin care immediately after birth and cord cutting with a clean instrument were marginally higher in the intervention arm versus the control arm (80.7% vs. 72.2%; p=0.071 and 88.1% vs. 84.4%; p=0.023, respectively. Half (49.6% of the mothers in the intervention arm waited more than 24 hours to bathe the baby, compared to 35.5% in

    We performed serial Health Care Utilization and Attitudes Surveys (HUASs) among caretakers of children ages 0-59 months randomly selected from demographically defined populations participating in the Global Enteric Multicenter Study (GEMS), a case-control study of moderate-to-severe diarrhea (MSD) in seven developing countries. The surveys aimed to estimate the proportion of children with MSD who would present to sentinel health centers (SHCs) where GEMS case recruitment would occur and provide a basis for adjusting disease incidence rates to include cases not seen at the SHCs. The proportion of children at each site reported to have had an incident episode of MSD during the 7 days preceding the survey ranged from 0.7% to 4.4% for infants (0-11 months of age), from 0.4% to 4.7% for toddlers (12-23 months of age), and from 0.3% to 2.4% for preschoolers (24-59 months of age). The proportion of MSD episodes at each site taken to an SHC within 7 days of diarrhea onset was 15-56%, 17-64%, and 7-33% in the three age strata, respectively. High cost of care and insufficient knowledge about danger signs were associated with lack of any care-seeking outside the home. Most children were not offered recommended fluids and continuing feeds at home. We have shown the utility of serial HUASs as a tool for optimizing operational and methodological issues related to the performance of a large case-control study and deriving population-based incidence rates of MSD. Moreover, the surveys suggest key targets for educational interventions that might improve the outcome of diarrheal diseases in low-resource settings.

    This study evaluated malaria care-seeking behaviour, as well as the prevalence of parasitaemia and anaemia among pregnant women attending antenatal clinics of two tertiary healthcare facilities in Edo State, Nigeria. Malaria was highly prevalent in the study group (20% by microscopy and estimated 25% by PCR), but parasitaemia and incidence decreased with increasing number of pregnancies. Although the level of education of the study participants was relatively high, antimalarial control measures during pregnancy were found to be poorly utilised by the women and malaria care-seeking was often delayed. A minority of the interviewed pregnant women said they had received sulphadoxine/pyrimethamine-based intermittent preventive therapy (IPT) during current pregnancy. Moreover, the use of inferior antimalaria treatment (e.g. chloroquine) was frequent. The majority of the pregnant women, mainly primigravidae, were anaemic. Efforts to improve antimalaria healthcare must be intensified, targeting pregnant women, particularly the primigravidae and secundigravidae and the healthcare providers.

    Full Text Available Abstract Background Diarrhea remains the second leading cause of death in children under 5 years of age in sub-Saharan Africa. Health care seeking behavior for diarrhea varies by context and has important implications for developing appropriate care strategies and estimating burden of disease. The objective of this study was to determine the proportion of children under five with diarrhea who consulted at a health structure in order to identify the appropriate health care levels to set up surveillance of severe diarrheal diseases. Methods A cluster survey was done on 35 clusters of 21 children under 5 years of age in each of four districts of the Maradi Region, Niger. Caretakers were asked about diarrhea of the child during the recall period and their health seeking behavior in case of diarrhea. A weighted cluster analysis was conducted to determine the prevalence of diarrhea, as well as the proportion of consultations and types of health structures consulted. Results In total, the period prevalence of diarrhea and severe diarrhea between April 24th and May 21st 2009 were 36.8% (95% CI: 33.7 - 40.0 and 3.4% (95% CI: 2.2-4.6, respectively. Of those reporting an episode of diarrhea during the recall period, 70.4% (95% CI: 66.6-74.1 reported seeking care at a health structure. The main health structures visited were health centers, followed by health posts both for simple or severe diarrhea. Less than 10% of the children were brought to the hospital. The proportion of consultations was not associated with the level of education of the caretaker, but increased with the number of children in the household. Conclusions The proportion of consultations for diarrhea cases in children under 5 years old was higher than those reported in previous surveys in Niger and elsewhere. Free health care for under 5 years old might have participated in this improvement. In this type of decentralized health systems, the WHO recommended hospital-based surveillance of

    Men who have sex with men (MSM) has become the group with the fastest growing HIV epidemic in China. Since many Chinese MSM are conducting HIV self-testing, we aimed to determine the rate of HIV care seeking after self-testing, examine characteristics of "seekers" compared to "non-seekers," and explore factors associated with HIV care-seeking behaviour. A cross-sectional study design was used and an online survey was conducted in Beijing, China in 2016, among users of a popular Chinese gay networking smart phone application. Chi-square test was used to compare characteristics of those who sought HIV care ("seekers") and those who did not ("non-seekers"). Univariate and multivariate logistic regression analyses were conducted to assess factors associated with HIV care seeking. Among 21,785 screened, 2383 participants (10.9%) were included in the study. A total of 380 participants (15.9%) reported seeking HIV care after HIV self-testing while 2003 (84.1%) did not. Lack of knowledge of the "window period" (adjusted odds ratio [AOR] = 0.68, 95% confidence interval [95% CI] = 0.47-0.97, P = 0.04) was associated with reduced odds of seeking HIV care, while lower monthly income (AOR = 1.29, 95% CI = 1.03-1.62, P = 0.03) and obtaining HIV self-testing kits from health facilities (AOR = 2.40, 95% CI = 1.81-3.17, P seeking HIV care. Among those who sought HIV care, a large majority (92.4%) had non-reactive HIV self-testing results. Only 29 out of 265 with reactive, uncertain, or unknown results sought HIV care. We found a very low rate of HIV care seeking among our sample of urban Chinese MSM. The observation that most with reactive, uncertain, or unknown results did not seek HIV care is a cause for concern. These people should be paid more attention and helped to enter the care cascade. Our findings highlight that interventions aimed at improving linkage to care after HIV self-testing are urgently needed. However, further study is required to inform the

    Local understandings of malaria and use of preventive measures-are critical factors in sustained control of malaria. This study assessed caretakers' knowledge on malaria, use of Long Lasting Insecticide Treated Nets (LLINs) and care-seeking behavior for their children's illness in different malaria transmission settings of Ethiopia. Data were collected from 709 caretakers of children of 2-9 years of age during in 2016. A standard questionnaire was used to assess caretakers' perceptions of malaria, use of LLIN and care seeking behavior for febrile illness of children aged 2-9 years. The caretakers recognized malaria mostly by chills (70.4%, 499/709), fever (45.7%, 324/709) and headache (39.8%, 282/709). Overall, only 66.4% (471) of the caretakers knew that mosquito bite caused malaria and that it was quite heterogeneous by localities (ranging from 26.1% to 89.4%) and altitude (p malaria. Overall knowledge on malaria (mean = 51.2%) was very low with significant variations by localities, altitude and levels of malaria transmission, being low in high altitude and low in transmission areas (p malaria related knowledge items, only knowledge of LLIN was associated with net use; non-use of LLN was higher among caretakers who did not know the role of LLIN (AOR = 0.47, 95%CI: 0.28-0.77, p = 0.003). Of course, attributing causation of malaria to stagnant water discouraged use of net (p = 0.021). Of febrile children (n = 122), only 50 (41.0%) sought care with only 17 (34.0%) seeking the care promptly. There was no significant link between knowledge of malaria and care seeking behavior (p > 0.05). However, knowledge of malaria had some level of influence on treatment source preference where caretakers with greater knowledge preferred pharmacy as source of care. The findings demonstrated that caretakers' understanding of malaria was unsatisfactory with marked heterogeneity by localities. The present evidence suggests that knowledge is not sufficient

    This study aims to evaluate condom use, sexually transmitted infection (STI) screening, and knowledge of STI symptoms among female sex workers in Peru associated with sex work venues and a community randomised trial of STI control. One component of the Peru PREVEN intervention conducted mobile-team outreach to female sex workers to reduce STIs and increase condom use and access to government clinics for STI screening and evaluation. Prevalence ratios were calculated using multivariate Poisson regression models with robust standard errors, clustering by city. As-treated analyses were conducted to assess outcomes associated with reported exposure to the intervention. Care-seeking was more frequent in intervention communities, but differences were not statistically significant. Female sex workers reporting exposure to the intervention had a significantly higher likelihood of condom use, STI screening at public health clinics, and symptom recognition compared to those not exposed. Compared with street- or bar-based female sex workers, brothel-based female sex workers reported significantly higher rates of condom use with last client, recent screening exams for STIs, and HIV testing. Brothel-based female sex workers also more often reported knowledge of STIs and recognition of STI symptoms in women and in men. Interventions to promote STI detection and prevention among female sex workers in Peru should consider structural or regulatory factors related to sex work venues. © The Author(s) 2015.

    To reduce the burden of disease from malaria, innovative approaches are needed to engender behavior change. One unobservable, but fundamental trait-preferences for risk-may influence individuals' willingness to adopt new health technologies. We explore the association of risk preferences with malaria care-seeking behavior and the acceptability of malaria rapid diagnostic tests (RDTs) to inform RDT scale-up plans. In Oyo State, Nigeria, adult customers purchasing anti-malarial medications at selected drug shops took surveys and received an RDT as they exited. After an initial risk preference assessment via a simple lottery game choice, individuals were given their RDT result and treatment advice, and called four days later to assess treatment adherence. We used bivariable and multivariable regression analysis to assess the association of risk game choices with malaria care-seeking behaviors and RDT acceptability. Of 448 respondents, 63.2% chose the lottery game with zero variance in expected payout, 27.9% chose the game with low variance, and 8.9% chose the game with high variance. Compared to participants who chose lower variance games, individuals choosing higher variance games were older, less educated, more likely to be male, and were more likely to patronize lower quality drug shops, seek care immediately, and report complete disability due to their illness. In contrast, individuals choosing lower variance games were more likely to follow the correct treatment directions and were more likely to report an increase in their willingness to pay for an RDT compared to other risk groups, our two measures of RDT acceptability. Differences in estimated associations between risk game choices and selected care-seeking behaviors remained after controlling sociodemographic confounders. The uptake of health diagnostic information in terms of translating the RDT experience into willingness to pay for an RDT and treatment adherence to test results may vary according to risk

    Full Text Available Introduction: Reproductive tract infections including sexually transmitted infections (RTI/STIs are problems of public health priority compromising the reproductive health of women especially in developing countries. The problem is compounded by the poor health care seeking behaviour among women due to lack of awareness and sociocultural factors. Objectives: This study is an attempt to assess the health care seeking behaviour of women reporting RTI symptoms in a rural area of Tamil Nadu state of India and to examine the association of background sociodemographic characteristics with Health care seeking behaviour. Methodology: This was a cross sectional, descriptive study conducted between March to November 2011, among married women aged 18-45 years in a rural area of Kancheepuram district, Tamil Nadu in India. The required sample size was chosen by simple random sampling. The participants were administered a standardized, semi-structured schedule. Results: 520 women participated in the study. 173 women (33.3% of women reported experiencing symptoms of RTI/STI in the past 12 months. Only 51.45% of those who had RTI/STI symptoms sought health care. Private health care facility was preferred by nearly two-thirds. The health care seeking behaviour showed significant association with age group of women, religion, occupational status, type of family and socioeconomic status. Conclusion: There is a need for increasing awareness among women regarding RTI/STIs and their sequelae. Targeted health education programmes should be necessary to improve health care seeking among women.

    We present qualitative research findings on care-seeking and treatment uptake for pneumonia, diarrhoea and malaria among children under 5 in Kenya, Nigeria and Niger. The study aimed to determine the barriers caregivers face in accessing treatment for these conditions; to identify local solutions that facilitate more timely access to treatment; and to present these findings as a platform from which to develop context-specific strategies to improve care-seeking for childhood illness. Kenya, Nigeria and Niger are three high burden countries with low rates of related treatment coverage, particularly in underserved areas. Data were collected in Homa Bay County in Nyanza Province, Kenya; in Kebbi and Cross River States, Nigeria; and in the Maradi and Tillabéri regions of Niger. Primary caregivers of children under 5 who did not regularly engage with health services or present their child at a health facility during illness episodes were purposively selected for interview. Data underwent rigorous thematic analysis. We organise the identified barriers and related solutions by theme: financial barriers; distance/location of health facilities; socio-cultural barriers and gender dynamics; knowledge and information barriers; and health facility deterrents. The relative importance of each differed by locality. Participant suggested solutions ranged from community-level actions to facility-level and more policy-oriented actions, plus actions to change underlying problems such as social perceptions and practices and gender dynamics. We discuss the feasibility and implications of these suggested solutions. Given the high burden of childhood morbidity and mortality due to pneumonia, diarrhoea and malaria in Kenya, Nigeria and Niger, this study provides important insights relating to demand-side barriers and locally proposed solutions. Significant advancements are possible when communities participate in both problem identification and resolution, and are engaged as important

    To better understand how stock-outs of the first line antimalarial, Artemisinin-based Combination Therapy (ACT) and other non-compliant health worker behaviour, influence household expenditures during care-seeking for fever in the Ulanga District in Tanzania. We combined weekly ACT stock data for the period 2009-2011 from six health facilities in the Ulanga District in Tanzania, together with household data from 333 respondents on the cost of fever care-seeking in Ulanga during the same time period to establish how health seeking behaviour and expenditure might vary depending on ACT availability in their nearest health facility. Irrespective of ACT stock-outs, more than half (58%) of respondents sought initial care in the public sector, the remainder seeking care in the private sector where expenditure was higher by 19%. Over half (54%) of respondents who went to the public sector reported incidences of non-compliant behaviour by the attending health worker (e.g. charging those who were eligible for free service or referring patients to the private sector despite ACT stock), which increased household expenditure per fever episode from USD0.14 to USD1.76. ACT stock-outs were considered to be the result of non-compliant behaviour of others in the health system and increased household expenditure by 21%; however we lacked sufficient statistical power to confirm this finding. System design and governance challenges in the Tanzanian health system have resulted in numerous ACT stock-outs and frequent non-compliant public sector health worker behaviour, both of which increase out-of-pocket health expenditure. Interventions are urgently needed to ensure a stable supply of ACT in the public sector and increase health worker accountability.

    Given the large burden of non-communicable diseases (NCDs) among both Syrian refugees and the host communities within which they are settled, humanitarian actors and the government of Lebanon face immense challenges in addressing health needs. This study assessed health status, unmet needs, and utilization of health services among Syrian refugees and host communities in Lebanon. A cross-sectional survey of Syrian refugees and host communities in Lebanon was conducted using a two-stage cluster survey design with probability proportional to size sampling. To obtain information on chronic NCDs, respondents were asked a series of questions about hypertension, cardiovascular disease, diabetes, chronic respiratory disease, and arthritis. Differences in household characteristics by care-seeking for these conditions were examined using chi-square, t-test, and adjusted logistic regression methods. Over half (50.4 %) of refugee and host community households (60.2 %) reported a member with one of the five NCDs. Host community prevalence rates were significantly higher than refugees for all conditions except chronic respiratory diseases ( p  = 0.08). Care-seeking for NCDs among refugees and host community households was high across all conditions with 82.9 and 97.8 %, respectively, having sought care in Lebanon for their condition. Refugees utilized primary health care centers (PHCC) (57.7 %) most often while host communities sought care most in private clinics (62.4 %). Overall, 69.7 % of refugees and 82.7 % of host community members reported an out-of-pocket consultation payment ( p  = 0.041) with an average payment of US$15 among refugees and US$42 for the host community ( p Syrian crisis and the burden on the Lebanese health system, implications for both individuals with NCDs and Lebanon's health system are immense. The burden of out of pocket expenses on persons with NCDs are also substantial, especially given the tenuous economic status of many refugees

    Full Text Available Abstract Background The main killer diseases of children all manifest as acute febrile illness, yet are curable with timely and adequate management. To avoid a fatal outcome, three essential steps must be completed: caretakers must recognize illness, decide to seek care and reach an appropriate source of care, and then receive appropriate treatment. In a fatal outcome some or all of these steps have failed and it remains to be elucidated to what extent these fatal outcomes are caused by local disease perceptions, inappropriate care-seeking or inadequate resources in the family or health system. This study explores caretakers' experiences of care-seeking for childhood febrile illness with fatal outcome in rural Uganda to elucidate the most influential barriers to adequate care. Methods A mixed methods approach using structured Verbal/Social autopsy interviews and in-depth interviews was employed with 26 caretakers living in Iganga/Mayuge Demographic Surveillance Site who had lost a child 1–59 months old due to acute febrile illness between March and June 2006. In-depth interviews were analysed using content analysis with deductive category application. Results Final categories of barriers to care were: 1 "Illness interpretation barriers" involving children who received delayed or inappropriate care due to caretakers' labelling of the illness, 2 "Barriers to seeking care" with gender roles and household financial constraints hindering adequate care and 3 "Barriers to receiving adequate treatment" revealing discontents with providers and possible deficiencies in quality of care. Resource constraints were identified as the underlying theme for adequate management, both at individual and at health system levels. Conclusion The management of severely ill children in this rural setting has several shortcomings. However, the majority of children were seen by an allopathic health care provider during the final illness. Improvements of basic health care

    The clinical knowledge of factors related to the spread of pain on the body has increased and understanding these factors is essential for effective pain treatment. This population-based study examines local (LP), regional (RP), and widespread pain (WSP) on the body regarding comorbidities, pain aspects, and impact of pain and elucidates how the spread of pain varies over time. A postal questionnaire that addressed pain aspects (intensity, frequency, duration and anatomical spreading on a body manikin), comorbidities and implications of pain (i.e., work situation, physical activity, consumption of health care and experience of hospitality and treatment of health care) was sent to 9000 adults living in southeastern Sweden. Of these, 4774 (53 %) completed and returned the questionnaire. After 9 weeks, a follow-up questionnaire was sent to the 2983 participants who reported pain in the first questionnaire (i.e. 62 % of 4774 subjects). Of these, 1940 completed and returned the questionnaire (i.e. 65 % of 2983 subjects). The follow-up questionnaire included the same items as the first questionnaire. This study found differences in intensity, frequency and duration of pain, comorbidities, aspects of daily functioning and health care seeking in three pain categories based on spreading of pain: LP, RP and WSP. Compared to the participants with RP and LP, the participants with WSP had lower education and worse overall health, including more frequent heart disease and hypertension. In addition, participants with WSP had more intense, frequent, and long-standing pain, required more medical consultations, and experienced more impact on work. The participants with RP constituted an intermediate group regarding frequency and intensity of pain, and impact on work. The participants with LP were the least affected group regarding these factors. A substantial transition to RP had occurred by the 9-week follow-up. This study shows an association between increased spread of pain

    This study was carried out to understand the role social determinants and health seeking behavior among rice farming and pastoral communities in Kilosa District in central Tanzania. The study involved four villages; two with rice farming communities while the other two with pastoral communities. In each village, heads of households or their spouses were interviewed to seek information on livelihoods activities, knowledge and practices on malaria and its preventions. A total of 471 individuals (males=38.9%; females=61.1%) were interviewed. Only 23.5% of the respondents had adequate knowledge on malaria. Fifty-six percent of the respondents could not associate any livelihood activity with malaria transmission. Majority (79%) of the respondents believed that most of fevers were due to malaria; this was higher among the pastoral (81.7%) than rice farming communities (76.1%) (p=0.038). Cases of fever were significantly higher in households with non-educated (31.2%) than educated respondents (21.5%). Women experienced significantly more episodes of fever than men (ppastoral than rice farming communities (ppastoral communities (p=0.05). In conclusion, education, sex, availability of health care facility and livelihood practices were the major social determinants that influence malaria acquisition and care seeking pattern in central Tanzania. Appropriate public health promotion should be designed to address the links of livelihoods and malaria transmission among rural farming communities in an ecohealth approach.

    Female genital mutilation (FGM) has become recognized worldwide as an extreme form of violation of the human rights of girls and women. Strategies have been employed to curb the practice. To conduct a systematic review of randomized and nonrandomized studies of the effects of providing educational interventions on the body image and care-seeking behavior of girls and women living with FGM with the view to ending the practice. CENTRAL, MEDLINE, and other databases were searched up to August 10, 2015 without any language restrictions. Studies that provided education to women and/or girls living with any type of FGM or residing in countries where FGM is predominantly practiced were included. Two authors independently screened and collected data. We summarized dichotomous outcomes using odds ratios and evidence was assessed using the GRADE system (Grading of Recommendations Assessment, Development, and Evaluation). Educational interventions resulted in fewer women recommending FGM for their daughters and also reduced the incidence of FGM cases among daughters of women who received the educational interventions. These findings need to be validated with large randomized trials. 42015024637. © 2017 International Federation of Gynecology and Obstetrics.

    Low-and middle-income (LMIC) countries account for 90% of all reported burns, nevertheless there is a paucity of providers to treat burns. Current studies on burns in LMICs have not evaluated the gap between care seeking and receiving. This study explores this gap across socioeconomically similar populations in a multi-country population based assessment to inform burn care strategies. The Surgeons OverSeas Assessment of Surgical Need (SOSAS) instrument is a cross sectional national, cluster random sampling survey administered in Nepal, Rwanda, Sierra Leone, and Uganda from 2011 to 2014. The survey identifies burn etiology, demographics, timing, disability, and barriers to receiving care. Among 13,763 individuals surveyed, 896 burns were identified. Rwanda had the highest proportion of individuals seeking and receiving care (91.6% vs 88.5%) while Sierra Leone reported the fewest (79.3% vs 70.3%). Rwanda reported the largest disability while Nepal reported the highest proportion with no disability (47.5% vs 76.2%). Lack of money, healthcare providers, and rural living reduce the odds of receiving care by 68% and 85% respectively. Despite similar country socioeconomic characteristics there was significant variability in burn demographics, timing, and disability. Nevertheless, being geographically and economically disadvantaged predict lack of access to burn care. Copyright © 2018 Elsevier Ltd and ISBI. All rights reserved.

    In the United States, considerable geographic variation in the rates of culture-confirmed Campylobacter infection has been consistently observed among sites participating in the Foodborne Diseases Active Surveillance Network (FoodNet). We used data from the FoodNet Population Surveys and a FoodNet case-control study of sporadic infection to examine whether differences in medical care seeking, medical practices, or risk factors contributed to geographic variation in incidence. We found differences across the FoodNet sites in the proportion of persons seeking medical care for an acute campylobacteriosis-like illness (range, 24.9%-43.5%) and in the proportion of ill persons who submitted a stool sample (range, 18.6%-40.7%), but these differences were not statistically significant. We found no evidence of geographic effect modification of previously identified risk factors for campylobacteriosis in the case-control study analysis. The prevalence of some exposures varied among control subjects in the FoodNet sites, including the proportion of controls reporting eating chicken at a commercial eating establishment (18.2%-46.1%); contact with animal stool (8.9%-30.9%); drinking water from a lake, river, or stream (0%-5.1%); and contact with a farm animal (2.1%-12.7%). However, these differences do not fully explain the geographic variation in campylobacteriosis. Future studies that quantify Campylobacter contamination in poultry or variation in host immunity may be useful in identifying sources of this geographic variation in incidence.

    To identify gaps in the use of HIV prevention and care services and commodities for female sex workers, we conducted a baseline cross-sectional survey in four cities, in the context of an implementation research project aiming to improve use of sexual and reproductive health services. Using respondent-driven sampling, 400 sex workers were recruited in Durban, 308 in Tete, 400 in Mombasa and 458 in Mysore and interviewed face-to-face. RDS-adjusted proportions were estimated by nonparametric bootstrapping and compared across cities using post hoc pairwise comparison. Condom use with last client ranged from 88.3% to 96.8%, ever female condom use from 1.6% to 37.9%, HIV testing within the past 6 months from 40.5% to 70.9%, receiving HIV treatment and care from 35.5% to 92.7%, care seeking for last STI from 74.4% to 87.6% and having had at least 10 contacts with a peer educator in the past year from 5.7% to 98.1%. Many of the differences between cities remained statistically significant (P < 0.05) after adjusting for differences in FSWs' socio-demographic characteristics. The use of HIV prevention and care by FSWs is often insufficient and differed greatly between cities. Differences could not be explained by variations in socio-demographic sex worker characteristics. Models to improve use of condoms and HIV prevention and care services should be tailored to the specific context of each site. Programmes at each site must focus on improving availability and uptake of those services that are currently least used. © 2016 John Wiley & Sons Ltd.

The Government of Pakistan has set the ambitious goal of zero deaths due to tuberculosis and universal access to tuberculosis care by 2020. Successfully reaching these goals is dependent on the country's capacity to diagnose and successfully treat an estimated 200000 unnotified or missing patients with tuberculosis. A patient-pathway analysis (PPA) was conducted at the national level, as well as for each of the 4 provinces, to assess the alignment between patient care seeking and the availability of tuberculosis diagnostic and treatment services. Almost 90% of patients initiated care in the private sector, which accounts for only 15% of facilities with the capacity for tuberculosis diagnosis and treatment. Across the country, nearly 50% of tuberculosis microscopy laboratories were located in public-sector-basic health units and regional health centers. However, very few patients initiated care in these facilities. Overall, tuberculosis case detection was high given the low likelihood of patients reaching facilities with the capacity for tuberculosis service delivery during their first visit. Improving the engagement of the informal sector and lower-level clinicians will improve the efficiency and timeliness of tuberculosis diagnosis for patients in Pakistan. Concurrently, the apparent strength of the referral networks connecting community-level workers and private clinicians to the public sector for tuberculosis diagnosis and treatment suggests that strengthening the capacity of the public sector could be valuable. © The Author 2017.

    Full Text Available The private medical care sector is expanding in urban cities in Sub-Saharan Africa (SSA. However, people's health-care-seeking behaviors in this new landscape remain poorly understood; furthermore, distinguishing between public and private providers and among various types of private providers is critical in this investigation. This study assessed, by type, the healthcare providers urban residents in Burkina Faso visit, and their choice determinants.We conducted a population-based survey of a representative sample of 1,600 households in Ouagadougou from July to November 2011, consisting of 5,820 adults. We assessed the types of providers people typically sought for severe and non-severe conditions. We applied generalized estimating equations in this study.Among those surveyed, 97.7% and 53.1% indicated that they seek a formal provider for treating severe and non-severe conditions, respectively. Among the formal provider seekers, 20.5% and 17.0% chose for-profit (FP providers for treating severe and non-severe conditions, respectively. Insurance coverage was held by 2.0% of those surveyed. Possessing insurance was the strongest predictor for seeking FP, for both severe (odds ratio [OR]  = 1.15, 95% confidence interval [CI] = 1.04-1.28, and non-severe conditions (OR = 1.22, 95% CI = 1.07-1.39. Other predictors included being a formal jobholder and holding a higher level education. By contrast, we observed no significant difference in predisposing, enabling, or need characteristics between not-for-profit (NFP provider seekers and public provider seekers. Proximity was the primary reason for choosing a provider.The results suggested that FP providers play a crucial role in the urban healthcare market in SSA. Socioeconomic status and insurance status are significant predictors of provider choice. The findings can serve as a crucial reference for policymakers in response to the emergence of FP providers in SSA.

    Performance-based financing (PBF) strategies are promoted as a supply-side, results-based financing mechanism to improve primary health care. This study estimated the effects of Rwanda's PBF program on less-incentivized child health services and examined the differential program impact by household poverty. Districts were allocated to intervention and comparison for PBF implementation in Rwanda. Using Demographic Health Survey data from 2005 to 2007-08, a community-level panel dataset of 5781 children less than 5 years of age from intervention and comparison districts was created. The impacts of PBF on reported childhood illness, facility care-seeking, and treatment received were estimated using a difference-in-differences model with community fixed effects. An interaction term between poverty and the program was estimated to identify the differential effect of PBF among children from poorer families. There was no measurable difference in estimated probability of reporting illness with diarrhea, fever or acute respiratory infections between the intervention and comparison groups. Seeking care at a facility for these illnesses increased over time, however no differential effect by PBF was seen. The estimated effect of PBF on receipt of treatment for poor children is 45 percentage points higher (p = 0.047) compared to the non-poor children seeking care for diarrhea or fever. PBF, a supply-side incentive program, improved the quality of treatment received by poor children conditional on patients seeking care, but it did not impact the propensity to seek care. These findings provide additional evidence that PBF incentivizes the critical role staff play in assuring quality services, but does little to influence consumer demand for these services. Efforts to improve child health need to address both supply and demand, with additional attention to barriers due to poverty if equity in service use is a concern.

    In remote rural areas of Pakistan, access to the maternal, newborn and child health (MNCH) care provided by a skilled health provider is quite difficult. There are many reasons such as women's restricted social mobility, lack of education, disenfranchised in decision making and poverty. To overcome these barriers and impediments in district Chitral, which is the largest territory in terms of geography in province Khyber Pakhtunkhwa, local women of reproductive age, were mobilized to form the Community Based Saving Groups (CBSGs) at the village level. In these CBSGs, they pool-in their money, and then provide soft loans to the expecting mothers to meet the expenses of delivery. Simultaneously, young literate women were identified from the local communities; they were trained as Community Midwives (CMWs), using national MNCH curriculum, and later deployed in their respective villages within the district. This study captured their perceptions about the formation of CBSGs to overcome the financial and social barriers, and subsequent use of CMW services. A qualitative enquiry was conducted with the delivered mothers and their husbands through gender specific separate focus group discussions, with CBSG members and with non-members in four different sites of District Chitral. CBSG member women were far more aware on health issues. Information sought from these forums brought a noticeable change in the health seeking practices. Seeking care from a trained birth attendant in the community became easier. Women associated with the CBSGs as members, expressed an increased access to money for utilizing the CMW services, better awareness on MNCH issues, and empowerment to decide for seeking care. CBSG have been an instrumental platform for social networking, helping each other in other household matters. Women have started using the services of CMW and the CBSGs have actually helped them overcome the financial barriers in health care seeking. Moreover, the CBSGs became a medium

    Our main objective was to analyze individual determinants that lead middle-aged women to seek medical care for urinary incontinence (UI). Observational longitudinal study among GAZEL cohort participants: 2,640 women aged 50-62 completed a self-administered questionnaire at baseline. Eight years later (2008) 2,273 (86%) responded to a follow-up questionnaire. Seeking care for UI was defined as any consultation for UI during the 8-year follow-up period. Individual determinants considered in the regression analysis were social and demographic characteristics, social relations, UI type and severity, and other health factors. Among 1,192 women reporting incontinence at baseline, 24.4% had visited a physician at least once for UI during the follow-up period (56.0% of those reporting severe UI). The care-seeking rate increased with age at baseline. Multivariate analysis showed that women who reported severe UI (OR = 4.1; 95% CI 2.6-6.5), mixed UI (2.0; 1.3-3.0), or neurologic disease (1.6; 1.1-2.6), had weak social support (1.4; 1.0-2.0), or talked about their UI with close friends or family (1.5; 1.0-2.1) were more likely to seek care for UI. A model including these factors had a 78% probability of correctly differentiating women with incontinence who chose to seek care from those who did not. Our analysis could not take factors related to the organization of health services into account. Women do not always seek care for UI, even when it is severe. Besides UI severity and type, consultation is associated with aging, weak social support, conversation about it with close friends and family, and neurologic disorders. © 2013 Wiley Periodicals, Inc.

    Menstrual morbidity plays a significant role in adolescent females' lives. There are no studies to date reporting such data from menstrual health education programs in schools. The aim of our study was to report results from an audit of a menstrual health and endometriosis education program in secondary schools and observe age patterns of young women presenting for menstrual morbidity care. Audit data from education in secondary schools and audit data of patients from an Endometriosis and Pelvic Pain Coaching clinic operating in a private endometriosis specialised centre are reported. In a region of consistent delivery of the education program, student awareness of endometriosis was 32% in 2015. Overall in 2015, 13% of students experienced distressing menstrual symptoms and 27% of students sometimes or always missed school due to menstrual symptoms. Further, in one region of consistent delivery of the menstrual health education program, data show an increase in younger patients attending for specialised endometriosis care. There is strong suggestive evidence that consistent delivery of a menstrual health education program in schools increases adolescent student awareness of endometriosis. In addition, there is suggestive evidence that in a geographical area of consistent delivery of the program, a shift in earlier presentation of young women to a specialised health service is observed. © 2017 The Royal Australian and New Zealand College of Obstetricians and Gynaecologists.

    Full Text Available This paper presents a method of speech recognition by pattern recognition techniques. Learning consists in determining the unique characteristics of a word (cepstral coefficients by eliminating those characteristics that are different from one word to another. For learning and recognition, the system will build a dictionary of words by determining the characteristics of each word to be used in the recognition. Determining the characteristics of an audio signal consists in the following steps: noise removal, sampling it, applying Hamming window, switching to frequency domain through Fourier transform, calculating the magnitude spectrum, filtering data, determining cepstral coefficients.

    During the summer of 2014, ISIS overran Nineveh governorate in Northern Iraq. Yazidis and other religious minorities were subjected to brutal attacks and forced to seek refuge into the neighbouring Kurdistan Region, where they remain living in local communities or in camps. This survey provides a population-based assessment of the health needs and care seeking behaviours of Yazidis and other groups currently residing in camps. The survey covered 13 camps managed by the Kurdish Board of Relief and Humanitarian Affairs. A systematic random sample of 1,300 households with a total of 8,360 members were interviewed between November and December 2015. Participants were asked if any household members had needed care for a health condition in the two weeks preceding the survey, and whether care was obtained from the camp primary health care centre, an outside public hospital or a private clinic. If care was received, the out-of-pocket payment was recorded; otherwise, the reason for not seeking care was queried. In 33.9% (CI: 31.0-37.0) of households one or more members had needed care for a health condition in the two weeks preceding the survey. The most likely to have needed care were older persons (18.5%; CI: 13.6-24.6) and infants (18.0%; CI: 11.6-26.8). The reported health conditions revealed a complex picture of communicable and non-communicable diseases as well as mental health problems and physical injuries. Care was primarily sought from private clinics (41.8%; CI: 36.4-47.4) or public hospitals (27.3%; CI: 22.6-32.7) rather than from the camp primary health care clinics (23.6%; CI: 19.5-28.2). The mean out-of-pocket payment for care received was nearly 3 times higher in public hospitals than in the camp primary health care clinics and nearly 11 times higher in private clinics. Cost was the main perceived barrier to obtaining health services. Demand for health services was high among Yazidis and other minorities living in camps. Private services were preferred in

    The interpretation of sensations and the recognition of symptoms of a sickness, as well as the movement to seek treatment, have long been recognised in medical anthropology as inherently social processes. Based on cases of HIV and trauma (PTSD) in Uganda, we show that even the first signs...... and sensations of sickness can be radically social. The sensing body can be a ‘social body’ – a family, a couple, a network – a unit that transcends the individual body. In this article, we focus on four aspects of the sociality of sensations and symptoms: mode of transmission, the shared experience...... of sensations/symptoms, differential recognition of symptoms, and the embodied sociality of treatment....

    Fox, Philip C

    2008-01-01

    Awareness and recognition of xerostomia are essential in order to help patients minimize dryness symptoms, to institute preventive measures and to limit oral complications. The dental professional has the opportunity to ask every patient if they are experiencing dry mouth. In particular, complaints of dryness while eating, or difficulty swallowing dry foods, or the necessity of using liquids to ease swallowing are important clues that salivary function may be impaired. As part of a routine oral examination, one should examine the oral cavity carefully for signs of salivary gland dysfunction. Findings such as an increase in caries activity, mucosal alterations, infection or salivary gland enlargement may indicate salivary dysfunction. Evaluation should be conducted proactively at each patient visit. Early recognition will minimize damage and dysfunction and allow appropriate management to begin. Although the salivary dysfunction may be irreversible, preventive measures and conservative treatments can avoid or limit mucosal breakdown, infections and permanent damage to teeth. Adequate symptomatic relief is possible with local palliative and systemic measures in many patients. Appropriate management of symptoms and increasing saliva output may help patients feel more comfortable and improve their quality of life.

    A population-based case referent study. To determine whether current and past physical and psychosocial occupational factors are associated with care-seeking for low back pain in working men and women. The importance of physical and psychosocial workloads as causal factors of low back pain has mostly been investigated in special occupational groups and with a cross-sectional design, which makes generalizability and interpretations more difficult. The study comprised 2118 working men and women 20 to 59 years old (695 cases, and 1423 referents). Cases were defined as persons seeking care by any caregiver for low back pain. The exposure assessments were made through questionnaires and interviews about current and past physical and psychosocial loads during work and leisure time. In a logistic regression analysis, physical load from forward bending in men (RR = 1.8) and high physical load, in general, in women (RR = 2.0) showed increased relative risks. Psychosocial factors alone seemed to be of less importance in women, but "poor job satisfaction" and "mostly routine work without possibilities of learning" increased the risk in men. Combined current and past exposures further increased the risks. A combination of high physical and psychosocial loads increased the risk substantially, but few were exposed to such loads. Adjustment for lifestyle and other loads outside work did not change the results. Current and past physical and psychosocial occupational factors, both separately and combined, seem to be gender-specific, and to have a moderate impact on care-seeking for low back pain in a general working population.

    Reducing patient delay for patients afflicted by an acute myocardial infarction is a task of great complexity, which might be alleviated if more factors that influence this delay could be identified. Although a number of self-reported instruments associated with patient delay exist, none of these taps the content of the appraisal process related to patients' subjective emotions. The aim of this study was to develop and validate a questionnaire aimed at assessing patients' appraisal, emotions and action tendencies when afflicted by an acute myocardial infarction. An item pool was generated based on themes conceptualized in a recent qualitative study of acute myocardial infarction patients' thoughts, feelings and actions preceding the decision to seek medical care. The 'Think-Aloud Protocol' and test-retest analysis at item level were performed. The modified item pool was administered to 96 patients when treated for acute myocardial infarction. Explorative factor analysis and principal component analysis with the non-linear iterative partial least squares algorithm were performed to examine the underlying factor structure of the items. The findings indicated three core dimensions corresponding to three subscales, namely, 'symptom appraisal'; 'perceived inability to act'; 'autonomy preservation'. The results demonstrated acceptable measures of reliability and validity Conclusions: The PA-AMI questionnaire demonstrated satisfactory psychometric properties. Assessment of the included core dimensions may contribute to greater understanding of the appraisal processes for patients afflicted by an acute myocardial infarction.

    Single molecules in a tunnel junction can now be interrogated reliably using chemically functionalized electrodes. Monitoring stochastic bonding fluctuations between a ligand bound to one electrode and its target bound to a second electrode ('tethered molecule-pair' configuration) gives insight into the nature of the intermolecular bonding at a single molecule-pair level, and defines the requirements for reproducible tunneling data. Simulations show that there is an instability in the tunnel gap at large currents, and this results in a multiplicity of contacts with a corresponding spread in the measured currents. At small currents (i.e. large gaps) the gap is stable, and functionalizing a pair of electrodes with recognition reagents (the 'free-analyte' configuration) can generate a distinct tunneling signal when an analyte molecule is trapped in the gap. This opens up a new interface between chemistry and electronics with immediate implications for rapid sequencing of single DNA molecules. (topical review)

    This study aimed to compare the effectiveness of a high-intensity model (HIM) and a low-intensity model (LIM) of behaviour change communication interventions in Bihar and Jharkhand states of India designed to improve women's knowledge and usage of safe abortion services, as well as the dose effect of intervention exposure. We conducted two cross-sectional household surveys among married women aged 15-49 years in intervention and comparison districts. Difference-in-difference models were used to assess the efficacy of the intervention, adjusting for sociodemographic characteristics. Although both intervention types improved abortion knowledge, the HIM intervention was more effective in improving comprehensive knowledge about abortion. In particular, there were improvements in knowledge on legality of abortion (AOR=2.2; 95% CI 1.6 to 2.9) and nearby sources of safe abortion care (AOR=1.7; 95% CI 1.2 to 1.3). Higher level of exposure to abortion-related messages was related to more accurate knowledge about abortion within both intervention groups. Evidence was mixed on changes in abortion care-seeking behaviour. More work is needed to ensure that women seek safe abortion services in lieu of informal services that may be more likely to lead to postabortion complications.

    Breast cancer survival rates in lower-income countries like Bangladesh are approximately 50%, versus over 80% in high income countries. Anecdotal reports suggest that, beyond economic and health system barriers, sociocultural factors may influence a woman's care-seeking behavior and resultant early stage diagnoses. To understand these barriers, we conducted 63 interviews (43 women with breast cancer symptoms and 20 men) in Khulna, Bangladesh. We identified socio-cultural barriers like neglect and indifference toward women, women's lack of power to use resources, and reduced support from family due to stigma. Interventions must address these barriers and improve the status of women in Bangladesh.

  3. Professional care seeking for mental health problems among women and men in Europe: the role of socioeconomic, family-related and mental health status factors in explaining gender differences.

    This comparative study examines cross-national variation in gender differences in primary and specialized mental health care use in Europe. We investigate to what extent socioeconomic, family-related, and mental health factors explain the gender difference, and how the impact of these groups of determinants on gender differences in mental health care use varies between countries. Data from the Eurobarometer 248 (2005-2006) for 29 European countries is used and country-specific logistic regression analyses are performed. Gender differences in professional care seeking are largely need based. In almost one-third of the countries examined, the gender difference is mainly attributable to women's poorer mental health status. However, in some countries, family and socioeconomic characteristics also have an independent contribution to the gender difference in mental health care use. Women's higher likelihood of a lower socioeconomic position, might partly explain their higher primary care use, while in some countries, it restricts their specialized care use. In addition, some social conditions, as having children and being widowed, seem to function in a few countries as suppressors of women's care use. Our study has shown that the gender difference in mental health care use, with women having a higher care use, is not a consistent European phenomenon and is dependent on the type of care provider, with greater gender inequity in the use of primary health care. The social roles adopted by men and women have in some countries on top of the mental health status a relevant influence on the greater tendency among women to contact a care provider. How the socioeconomic and family characteristics moderate the relation between gender and mental health care use is not straightforward and country dependent.

    Qualified decision-making for the improved management of sexually transmitted infections (STIs) requires various sources of information. We aimed to estimate the STI-associated symptom prevalence and care-seeking patterns in the general population of Iran. In 2014, using a street-based survey with a standard gender-specific questionnaire on STI-associated symptoms and willingness to seek treatment, we interviewed 9166 Iranian participants, who were selected from among the 18-60-year-old population using multistage sampling. Data were analysed via generalised estimating equation and survey analysis, taking into account a 95% confidence coefficient. About 67.3% of participants, mean age 33 years, were 'assumed sexually active' and were therefore eligible for inclusion. Approximately 39.9% (95% CI 28.4% to 51.4%) of women and 17.6% (95% CI 13.9% to 21.6%) of men reported at least one STI-associated symptom in the current week. The occurrence of symptoms decreased with an increase in age in both genders (pSTI-associated symptoms in Iranian adults is considerable. The results emphasise the need for appropriate and timely STI care and more attention to sexual health promotion to mitigate onward and future infections. Attention to the care-seeking pattern is fundamental to policymaking and planning. Published by the BMJ Publishing Group Limited.

    , proprioperception which can be assessed with many evaluation tools: PAS, TDI, BSABS, SPI-A. The German school points to the fact that patients experimenting such changes could potentially be aware of their state. On the other hand, the Anglo-Saxon school refers to the detection of an "at risk" population. The Anglo-Saxons no longer refer to "prodromal symptoms" but rather to a "prodromal period" that extends to about one Year. This period would begin with the patient's first behavioral changes and extend until the first psychotic episode. Both schools agree that, at this stage, neither the recognition nor the description of the period preceding psychosis allows to effectively predict it. As a result, some Authors continue to refer to psychological changes forming a risk factor for the development of subsequent psychosis, rather than clear predictors of inevitable illness. As for relapses, prodromal signs and symptoms found in schizophrenic patients are both specific and non-specific. In most cases, patients experiment perceptions and behavioral changes before psychosis exacerbation. It is not uncommon for a substantial increase in prodromal symptoms to be followed by degradation in psychotic symptoms. On the other hand, many such increases in psychotic symptoms were not preceded by increases in possible prodromal symptoms; hence their importance in identifying the timing of an intervention, but many relapses will occur regardless of the detection of said symptoms.

  12. Multimodal eye recognition

    Zhou, Zhi; Du, Yingzi; Thomas, N. L.; Delp, Edward J., III

    2010-04-01

    Multimodal biometrics use more than one means of biometric identification to achieve higher recognition accuracy, since sometimes a unimodal biometric is not good enough used to do identification and classification. In this paper, we proposed a multimodal eye recognition system, which can obtain both iris and sclera patterns from one color eye image. Gabor filter and 1-D Log-Gabor filter algorithms have been applied as the iris recognition algorithms. In sclera recognition, we introduced automatic sclera segmentation, sclera pattern enhancement, sclera pattern template generation, and sclera pattern matching. We applied kernelbased matching score fusion to improve the performance of the eye recognition system. The experimental results show that the proposed eye recognition method can achieve better performance compared to unimodal biometric identification, and the accuracy of our proposed kernel-based matching score fusion method is higher than two classic linear matching score fusion methods: Principal Component Analysis (PCA) and Linear Discriminant Analysis (LDA).

    2011-06-01

    Ocular recognition is a new area of biometric investigation targeted at overcoming the limitations of iris recognition performance in the presence of non-ideal data. There are several advantages for increasing the area beyond the iris, yet there are also key issues that must be addressed such as size of the ocular region, factors affecting performance, and appropriate corpora to study these factors in isolation. In this paper, we explore and identify some of these issues with the goal of better defining parameters for ocular recognition. An empirical study is performed where iris recognition methods are contrasted with texture and point operators on existing iris and face datasets. The experimental results show a dramatic recognition performance gain when additional features are considered in the presence of poor quality iris data, offering strong evidence for extending interest beyond the iris. The experiments also highlight the need for the direct collection of additional ocular imagery.

    The complexities of the meanings of “to recognize” and “recognition” are important in their roles in the realm of justice. I include in the concept of justice, the judiciary, both civil and criminal; distributive justice; and, social and political justice. For each one of these, there are multiple meanings of recognition that are important to understanding their foundation and their scope. There are meanings of recognition that are relevant to other aspects of social justice as the recognition of marginal, oppressed, devalued, groups as deserving of being treated as equals. The structure of my paper is to go through the various meanings and categories of meanings of “to recognize” and “recognition.” I give an account of each of the types of justice and show how various kinds of recognition are relevant to each kind of justice.

  20. Recognition of handwriting from electromyography.

    Directory of Open Access Journals (Sweden)

    Michael Linderman

    Full Text Available Handwriting--one of the most important developments in human culture--is also a methodological tool in several scientific disciplines, most importantly handwriting recognition methods, graphology and medical diagnostics. Previous studies have relied largely on the analyses of handwritten traces or kinematic analysis of handwriting; whereas electromyographic (EMG signals associated with handwriting have received little attention. Here we show for the first time, a method in which EMG signals generated by hand and forearm muscles during handwriting activity are reliably translated into both algorithm-generated handwriting traces and font characters using decoding algorithms. Our results demonstrate the feasibility of recreating handwriting solely from EMG signals - the finding that can be utilized in computer peripherals and myoelectric prosthetic devices. Moreover, this approach may provide a rapid and sensitive method for diagnosing a variety of neurogenerative diseases before other symptoms become clear.

    People with Huntington's disease (HD) experience poor social quality of life, relationship breakdown, and social withdrawal, which are mediated to some extent by socially debilitating neuropsychiatric symptoms, such as apathy and disinhibition. Social cognitive symptoms, such as impaired emotion recognition, also occur in HD, however, the extent of their association with these socially debilitating neuropsychiatric symptoms is unknown. Our study examined the relationship between emotion recognition and symptom ratings of apathy and disinhibition in HD. Thirty-two people with premanifest or symptomatic-HD completed Part 1 of The Awareness of Social Inference Test (TASIT), which is a facial emotion recognition task. In addition, we obtained severity ratings for apathy and disinhibition on the Frontal Systems Behavior Scale (FrSBe) from a close family member. Our analyses used motor symptom severity as a proxy for disease progression. Emotion recognition performance was significantly associated with family-ratings of apathy, above and beyond their shared association with disease severity. We found a similar pattern for disinhibition ratings, which fell short of statistical significance. As expected, worse emotion recognition performance was correlated with higher severity in FrSBe symptom ratings. Our findings suggest that emotion recognition abilities relate to key socially debilitating neuropsychiatric symptoms in HD. Our results help to understand the functional significance of emotion recognition impairments in HD, and may have implications for the development of remediation programs aimed at improving patients' social quality of life.

    2018-03-01

    Nowadays, Named Entity Recognition (NER) system is used in medical texts to obtain important medical information, like diseases, symptoms, and drugs. While most NER systems are applied to formal medical texts, informal ones like those from social media (also called semi-formal texts) are starting to get recognition as a gold mine for medical information. We propose a theoretical Named Entity Recognition (NER) model for semi-formal medical texts in our medical knowledge management system by comparing two kinds of word representations: cluster-based word representation and distributed representation.

    Full Text Available The Recognition Heuristic (Gigerenzer and Goldstein, 1996; Goldstein and Gigerenzer, 2002 makes the counter-intuitive prediction that a decision maker utilizing less information may do as well as, or outperform, an idealized decision maker utilizing more information. We lay a theoretical foundation for the use of single-variable heuristics such as the Recognition Heuristic as an optimal decision strategy within a linear modeling framework. We identify conditions under which over-weighting a single predictor is a mini-max strategy among a class of a priori chosen weights based on decision heuristics with respect to a measure of statistical lack of fit we call ``risk''. These strategies, in turn, outperform standard multiple regression as long as the amount of data available is limited. We also show that, under related conditions, weighting only one variable and ignoring all others produces the same risk as ignoring the single variable and weighting all others. This approach has the advantage of generalizing beyond the original environment of the Recognition Heuristic to situations with more than two choice options, binary or continuous representations of recognition, and to other single variable heuristics. We analyze the structure of data used in some prior recognition tasks and find that it matches the sufficient conditions for optimality in our results. Rather than being a poor or adequate substitute for a compensatory model, the Recognition Heuristic closely approximates an optimal strategy when a decision maker has finite data about the world.

    2010-10-01

    Music has the potential to evoke strong emotions and plays a significant role in the lives of many people. Music might therefore be an ideal medium to assess emotion recognition. We investigated emotion recognition in music in 20 patients with idiopathic Parkinson's disease (PD) and 20 matched healthy volunteers. The role of cognitive dysfunction and other disease characteristics in emotion recognition was also evaluated. We used 32 musical excerpts that expressed happiness, sadness, fear or anger. PD patients were impaired in recognizing fear and anger in music. Fear recognition was associated with executive functions in PD patients and in healthy controls, but the emotion recognition impairments of PD patients persisted after adjusting for executive functioning. We found no differences in the recognition of happy or sad music. Emotion recognition was not related to depressive symptoms, disease duration or severity of motor symptoms. We conclude that PD patients are impaired in recognizing complex emotions in music. Although this impairment is related to executive dysfunction, our findings most likely reflect an additional primary deficit in emotional processing. 2010 Elsevier Inc. All rights reserved.

    Depressed patients are both characterized by social reality distorting maladaptive schemas and facial expression recognition impairments. The aim of the present study was to identify specific associations among symptom severity of depression, early maladaptive schemas and recognition patterns of facially expressed emotions. The subjects were inpatients, diagnosed with depression. We used 2 virtual humans for presenting the basic emotions to assess emotion recognition. The Symptom Check List 90 (SCL-90) was used as a self-report measure of psychiatric symptoms and the Beck Depression Inventory (BDI) was applied to assess symptoms of depression. The Young Schema Questionnaire Long Form (YSQ-L) was used to assess the presence of early maladaptive schemas. The recognition rate for happiness showed significant associations with both the BDI and the depression subscale of the SCL-90. After performing the second order factor analysis of the YSQ-L, we found statistically significant associations between the recognition indices of specific emotions and the main factors of the YSQ-L. In this study we found correlations between maladaptive schemas and emotion recognition impairments. While both domains likely contribute to the symptoms of depression, we believe that the results will help us to better understand the social cognitive deficits of depressed patients at the schema level and at the emotion recognition level.

    Miller, Larry

    1989-07-01

    No milestone has proven as elusive as the always-approaching "year of the LAN," but the "year of the scanner" might claim the silver medal. Desktop scanners have been around almost as long as personal computers. And everyone thinks they are used for obvious desktop-publishing and business tasks like scanning business documents, magazine articles and other pages, and translating those words into files your computer understands. But, until now, the reality fell far short of the promise. Because it's true that scanners deliver an accurate image of the page to your computer, but the software to recognize this text has been woefully disappointing. Old optical-character recognition (OCR) software recognized such a limited range of pages as to be virtually useless to real users. (For example, one OCR vendor specified 12-point Courier font from an IBM Selectric typewriter: the same font in 10-point, or from a Diablo printer, was unrecognizable!) Computer dealers have told me the chasm between OCR expectations and reality is so broad and deep that nine out of ten prospects leave their stores in disgust when they learn the limitations. And this is a very important, very unfortunate gap. Because the promise of recognition -- what people want it to do -- carries with it tremendous improvements in our productivity and ability to get tons of written documents into our computers where we can do real work with it. The good news is that a revolutionary new development effort has led to the new technology of "page recognition," which actually does deliver the promise we've always wanted from OCR. I'm sure every reader appreciates the breakthrough represented by the laser printer and page-makeup software, a combination so powerful it created new reasons for buying a computer. A similar breakthrough is happening right now in page recognition: the Macintosh (and, I must admit, other personal computers) equipped with a moderately priced scanner and OmniPage software (from Caere

    2016-12-01

    Indonesia has the highest human mortality from highly pathogenic avian influenza (HPAI) A (H5N1) virus infection in the world. A survey of households (N=2520) measured treatment sources and beliefs among symptomatic household members. A survey of physicians (N=554) in various types of health care facilities measured knowledge, assessment and testing behaviors, and perceived clinical capacity. Households reported confidence in health care system capacity but infrequently sought treatment for potential HPAI H5N1 signs/symptoms. More clinicians were confident in their knowledge of diagnosis and treatment than in the adequacy of related equipment and resources at their facilities. Physicians expressed awareness of the HPAI H5N1 suspect case definition, yet expressed only moderate knowledge in questioning symptomatic patients about exposures. Self-reported likelihood of testing for HPAI H5N1 virus was high after learning of certain exposures. Knowledge of antiviral treatment was moderate, but it was higher among clinicians in puskesmas. Physicians in private outpatient clinics, the most heavily used facilities, reported the lowest confidence in their diagnostic and treatment capabilities. Educational campaigns can encourage recall of possible poultry exposure when patients are experiencing signs/symptoms and can raise awareness of the effectiveness of antivirals to drive people to seek health care. Clinicians may benefit from training regarding exposure assessment and referral procedures, particularly in private clinics. (Disaster Med Public Health Preparedness. 2016;10:838-847).

  1. Tolerance and recognition

    Directory of Open Access Journals (Sweden)

    Hans Marius Hansteen

    2014-12-01

    Full Text Available Even though “toleration” and “recognition” designate opposing attitudes (to tolerate something, implies a negative stance towards it, whereas recognition seems to imply a positive one, the concepts do not constitute mutually exclusive alternatives. However, “toleration” is often associated with liberal universalism, focusing on individual rights, whereas “recognition” often connotes communitarian perspectives, focusing on relations and identity. This paper argues that toleration may be founded on recognition, and that recognition may imply toleration. In outlining a differentiated understanding of the relationship between toleration and recognition, it seems apt to avoid an all-to-general dichotomy between universalism and particularism or, in other words, to reach beyond the debate between liberalism and communitarianism in political philosophy.The paper takes as its starting point the view that the discussion on toleration and diversity in intercultural communication is one of the contexts where it seems important to get beyond the liberal/communitarian dichotomy. Some basic features of Rainer Forst’s theory of toleration and Axel Honneth’s theory of the struggle for recognition are presented, in order to develop a more substantial understanding of the relationship between the concepts of toleration and recognition. One lesson from Forst is that toleration is a normatively dependent concept, i.e., that it is impossible to deduce principles for toleration and its limits from a theory of toleration as such. A central lesson from Honneth is that recognition – understood as a basic human need – is always conflictual and therefore dynamic.Accordingly, a main point in the paper is that the theory of struggles for and about recognition (where struggles for designates struggles within an established order of recognition, and struggles about designates struggles that challenge established orders of recognition may clarify what

  11. Factors associated with consultation behaviour for primary symptoms potentially indicating colorectal cancer: A cross-sectional study on response to symptoms

    Science.gov (United States)

    2012-01-01

    Background Little data exists on the factors associated with health care seeking behaviour for primary symptoms of colorectal cancer (CRC). This study aimed to identify individual, provider and psychosocial factors associated with (i) ever seeking medical advice and (ii) seeking early medical advice for primary symptoms of colorectal cancer (CRC). Methods 1592 persons aged 56–88 years randomly selected from the Hunter Community Study (HCS) were sent a questionnaire. Results Males and those who had received screening advice from a doctor were at significantly higher odds of ever seeking medical advice for rectal bleeding. Persons who had private health coverage, consulted a doctor because the ‘symptom was serious’, or who did not wait to consult a doctor for another reason were at significantly higher odds of seeking early medical advice (seeking medical advice. Persons frequenting their GP less often and seeing their doctor because the symptom persisted were at significantly higher odds of seeking early medical advice (health messages to at-risk persons. This study identified modifiable factors, both individual and provider-related to consultation behaviour. Effective health promotion efforts must heed these factors and target sub-groups less likely to seek early medical advice. PMID:22862960

    Gambone, Elisabeth A.

    2018-01-01

    Spacecraft control algorithms must know the expected vehicle response to any command to the available control effectors, such as reaction thrusters or torque devices. Spacecraft control system design approaches have traditionally relied on the estimated vehicle mass properties to determine the desired force and moment, as well as knowledge of the effector performance to efficiently control the spacecraft. A pattern recognition approach was used to investigate the relationship between the control effector commands and spacecraft responses. Instead of supplying the approximated vehicle properties and the thruster performance characteristics, a database of information relating the thruster ring commands and the desired vehicle response was used for closed-loop control. A Monte Carlo simulation data set of the spacecraft dynamic response to effector commands was analyzed to establish the influence a command has on the behavior of the spacecraft. A tool developed at NASA Johnson Space Center to analyze flight dynamics Monte Carlo data sets through pattern recognition methods was used to perform this analysis. Once a comprehensive data set relating spacecraft responses with commands was established, it was used in place of traditional control methods and gains set. This pattern recognition approach was compared with traditional control algorithms to determine the potential benefits and uses.

    Combining different modalities for pattern recognition task is a very promising field. Basically, human always fuse information from different modalities to recognize object and perform inference, etc. Audio-Visual gender recognition is one of the most common task in human social communication. Human can identify the gender by facial appearance, by speech and also by body gait. Indeed, human gender recognition is a multi-modal data acquisition and processing procedure. However, computational multimodal gender recognition has not been extensively investigated in the literature. In this paper, speech and facial image are fused to perform a mutli-modal gender recognition for exploring the improvement of combining different modalities.

    Vision-based surveillance and monitoring is a potential alternative for early detection of respiratory disease outbreaks in urban areas complementing molecular diagnostics and hospital and doctor visit-based alert systems. Visible actions representing typical flu-like symptoms include sneeze and cough that are associated with changing patterns of hand to head distances, among others. The technical difficulties lie in the high complexity and large variation of those actions as well as numerous similar background actions such as scratching head, cell phone use, eating, drinking and so on. In this paper, we make a first attempt at the challenging problem of recognizing flu-like symptoms from videos. Since there was no related dataset available, we created a new public health dataset for action recognition that includes two major flu-like symptom related actions (sneeze and cough) and a number of background actions. We also developed a suitable novel algorithm by introducing two types of Action Matching Kernels, where both types aim to integrate two aspects of local features, namely the space-time layout and the Bag-of-Words representations. In particular, we show that the Pyramid Match Kernel and Spatial Pyramid Matching are both special cases of our proposed kernels. Besides experimenting on standard testbed, the proposed algorithm is evaluated also on the new sneeze and cough set. Empirically, we observe that our approach achieves competitive performance compared to the state-of-the-arts, while recognition on the new public health dataset is shown to be a non-trivial task even with simple single person unobstructed view. Our sneeze and cough video dataset and newly developed action recognition algorithm is the first of its kind and aims to kick-start the field of action recognition of flu-like symptoms from videos. It will be challenging but necessary in future developments to consider more complex real-life scenario of detecting these actions simultaneously from

    2017-05-01

    Emotion recognition, a social cognition domain, is impaired in people with schizophrenia and contributes to social dysfunction. Whether impaired emotion recognition emerges as a manifestation of illness or predates symptoms is unclear. Findings from studies of emotion recognition impairments in first-degree relatives of people with schizophrenia are mixed and, to our knowledge, no studies have investigated the link between emotion recognition and social functioning in that population. This study examined facial affect recognition and social skills in 16 offspring of parents with schizophrenia (familial high-risk/FHR) compared to 34 age- and sex-matched healthy controls (HC), ages 7-19. As hypothesised, FHR children exhibited impaired overall accuracy, accuracy in identifying fearful faces, and overall recognition speed relative to controls. Age-adjusted facial affect recognition accuracy scores predicted parent's overall rating of their child's social skills for both groups. This study supports the presence of facial affect recognition deficits in FHR children. Importantly, as the first known study to suggest the presence of these deficits in young, asymptomatic FHR children, it extends findings to a developmental stage predating symptoms. Further, findings point to a relationship between early emotion recognition and social skills. Improved characterisation of deficits in FHR children could inform early intervention.

    Body image disturbances and massive weight loss are major clinical symptoms of anorexia nervosa (AN). The aim of the present study was to examine the influence of body changes and eating attitudes on self-face recognition ability in AN. Twenty-seven subjects suffering from AN and 27 control participants performed a self-face recognition task (SFRT). During the task, digital morphs between their own face and a gender-matched unfamiliar face were presented in a random sequence. Participants' self-face recognition failures, cognitive flexibility, body concern and eating habits were assessed with the Self-Face Recognition Questionnaire (SFRQ), Trail Making Test (TMT), Body Shape Questionnaire (BSQ) and Eating Disorder Inventory-2 (EDI-2), respectively. Subjects suffering from AN exhibited significantly greater difficulties than control participants in identifying their own face (p = 0.028). No significant difference was observed between the two groups for TMT (all p > 0.1, non-significant). Regarding predictors of self-face recognition skills, there was a negative correlation between SFRT and body mass index (p = 0.01) and a positive correlation between SFRQ and EDI-2 (p recognition.

  2. ALGORITHM OF OBJECT RECOGNITION

    Full Text Available The second important problem to be resolved to the algorithm and its software, that comprises an automatic design of a complex closed circuit television system, represents object recognition, by virtue of which an image is transmitted by the video camera. Since imaging of almost any object is dependent on many factors, including its orientation in respect of the camera, lighting conditions, parameters of the registering system, static and dynamic parameters of the object itself, it is quite difficult to formalize the image and represent it in the form of a certain mathematical model. Therefore, methods of computer-aided visualization depend substantially on the problems to be solved. They can be rarely generalized. The majority of these methods are non-linear; therefore, there is a need to increase the computing power and complexity of algorithms to be able to process the image. This paper covers the research of visual object recognition and implementation of the algorithm in the view of the software application that operates in the real-time mode

    Fitzgerald, William A.; Firby, R. James

    2009-01-01

    Complex Event Recognition Architecture (CERA) is the name of a computational architecture, and software that implements the architecture, for recognizing complex event patterns that may be spread across multiple streams of input data. One of the main components of CERA is an intuitive event pattern language that simplifies what would otherwise be the complex, difficult tasks of creating logical descriptions of combinations of temporal events and defining rules for combining information from different sources over time. In this language, recognition patterns are defined in simple, declarative statements that combine point events from given input streams with those from other streams, using conjunction, disjunction, and negation. Patterns can be built on one another recursively to describe very rich, temporally extended combinations of events. Thereafter, a run-time matching algorithm in CERA efficiently matches these patterns against input data and signals when patterns are recognized. CERA can be used to monitor complex systems and to signal operators or initiate corrective actions when anomalous conditions are recognized. CERA can be run as a stand-alone monitoring system, or it can be integrated into a larger system to automatically trigger responses to changing environments or problematic situations.

  4. Radically enhanced molecular recognition

    2009-12-17

    The tendency for viologen radical cations to dimerize has been harnessed to establish a recognition motif based on their ability to form extremely strong inclusion complexes with cyclobis(paraquat-p-phenylene) in its diradical dicationic redox state. This previously unreported complex involving three bipyridinium cation radicals increases the versatility of host-guest chemistry, extending its practice beyond the traditional reliance on neutral and charged guests and hosts. In particular, transporting the concept of radical dimerization into the field of mechanically interlocked molecules introduces a higher level of control within molecular switches and machines. Herein, we report that bistable and tristable [2]rotaxanes can be switched by altering electrochemical potentials. In a tristable [2]rotaxane composed of a cyclobis(paraquat-p-phenylene) ring and a dumbbell with tetrathiafulvalene, dioxynaphthalene and bipyridinium recognition sites, the position of the ring can be switched. On oxidation, it moves from the tetrathiafulvalene to the dioxynaphthalene, and on reduction, to the bipyridinium radical cation, provided the ring is also reduced simultaneously to the diradical dication. © 2010 Macmillan Publishers Limited.

Iris recognition is one of the most secure and authentic among the other biometrics and this field demands more authentic, reliable and fast algorithms to implement these biometric systems in real time. In this paper, an efficient localization technique is presented to identify pupil and iris boundaries using histogram of the iris image. Two small portions of iris have been used for polar transformation to reduce computational time and to increase the efficiency of the system. Wavelet transform is used for feature vector generation. Rotation of iris is compensated without shifts in the iris code. System is tested on Multimedia University Iris Database and results show that proposed system has encouraging performance.

    Are simple strokes unique to the artist or designer who renders them? If so, can this idea be used to identify authorship or to classify artistic drawings? Also, could training methods be devised to develop particular styles? To answer these questions, we propose the Stroke Authorship Recognition (SAR) approach, a novel method that distinguishes the authorship of 2D digitized drawings. SAR converts a drawing into a histogram of stroke attributes that is discriminative of authorship. We provide extensive classification experiments on a large variety of data sets, which validate SAR\\'s ability to distinguish unique authorship of artists and designers. We also demonstrate the usefulness of SAR in several applications including the detection of fraudulent sketches, the training and monitoring of artists in learning a particular new style and the first quantitative way to measure the quality of automatic sketch synthesis tools. © 2015 The Eurographics Association and John Wiley & Sons Ltd.

    Population cohort studies are useful to study infectious diseases episodes not attended by health care services, but conventional paper diaries and questionnaires to capture cases are prone to noncompliance and recall bias. Use of smart technology in this setting may improve case finding. The objective of our study was to validate an interactive mobile app for monitoring occurrence of acute infectious diseases episodes in individuals, independent of health care seeking, using acute otitis media (AOM) symptom episodes in infants as a case study. We were interested in determining participant compliance and app performance in detecting and ascertaining (parent-reported) AOM symptom episodes with this novel tool compared with traditional methods used for monitoring study participants. We tested the InfectieApp research app to detect AOM symptom episodes. In 2013, we followed 155 children aged 0 to 3 years for 4 months. Parents recorded the presence of AOM symptoms in a paper diary for 4 consecutive months and completed additional disease questionnaires when AOM symptoms were present. In 2015 in a similar cohort of 69 children, parents used an AOM diary and questionnaire app instead. During conventional and app-based recording, 93.13% (17,244/18,516) and 94.56% (7438/7866) of symptom diaries were returned, respectively, and at least one symptom was recorded for 32.50% (n=5606) and 43.99% (n=3272) of diary days (Papp-based recording. The use of the study's smart diary app improved AOM case finding and disease questionnaire completeness. For common infectious diseases that often remain undetected by health care services, use of this technology can substantially improve the accurateness of disease burden estimates. ©Annemarijn C Prins-van Ginkel, Marieke LA de Hoog, C Uiterwaal, Henriette A Smit, Patricia CJ Bruijning-Verhagen.

    1994-09-01

    As the human immunodeficiency virus (HIV) epidemic affects more women, clinicians are increasingly observing pelvic inflammatory disease (PID) in HIV-infected women. The extent to which PID is a factor in the recognition of HIV or HIV is a factor in the recognition of PID is unknown. Even less is known about how HIV infection influences the development, clinical course, and microbiology of PID. The paucity of existing data largely results from difficulties in designing studies that are free of bias. Several biases may distort studies of the effect of HIV on the recognition, incidence, clinical presentation and course, and microbiology of PID. Selection bias, diagnostic bias, and confounding bias are the most likely causes of invalid conclusions in studies of the influence of HIV infection on these aspects of PID, for three major reasons: Factors that determine patients' health care seeking behavior may be related to HIV status; the diagnosis of PID tends to be imprecise; and extraneous factors that cause or prevent PID may be distributed differently in HIV-infected and HIV-uninfected women. Appropriate study design and analytic techniques can eliminate, reduce, or estimate the magnitude and direction of these biases, thereby yielding more valid conclusions. To interpret properly existing and future studies of the influence of HIV infection on PID, clinicians must consider several biases that may distort results.

  4. Recognition and Treatment of Nongonococcal Urethritis in Clinical Practice

    Nongonococcal urethritis is a relatively common disorder in sexually active individuals. The incidence is almost as high, if not higher, than gonorrhea. This syndrome may present with signs and symptoms indistinguishable from acute gonococcal urethritis. It is essential to differentiate the two diseases, as treatment protocols are different. Early recognition of nongonococcal urethritis and proper therapy will often lead to complete resolution and prevention of annoying complications. PMID:6999164

    A fundamental assumption underlying most current theories of amnesia is that memory impairments arise because previously studied information either is lost rapidly or is made inaccessible (i.e., the old information appears to be new). Recent studies in rodents have challenged this view, suggesting instead that under conditions of high interference, recognition memory impairments following medial temporal lobe damage arise because novel information appears as though it has been previously seen. Here, we developed a new object recognition memory paradigm that distinguished whether object recognition memory impairments were driven by previously viewed objects being treated as if they were novel or by novel objects falsely recognized as though they were previously seen. In this indirect, eyetracking-based passive viewing task, older adults at risk for mild cognitive impairment showed false recognition to high-interference novel items (with a significant degree of feature overlap with previously studied items) but normal novelty responses to low-interference novel items (with a lower degree of feature overlap). The indirect nature of the task minimized the effects of response bias and other memory-based decision processes, suggesting that these factors cannot solely account for false recognition. These findings support the counterintuitive notion that recognition memory impairments in this memory-impaired population are not characterized by forgetting but rather are driven by the failure to differentiate perceptually similar objects, leading to the false recognition of novel objects as having been seen before.

    Directory of Open Access Journals (Sweden)

    Angelo Vitório Cenci

    2015-01-01

    Full Text Available This paper addresses Honneth’s concept of autonomy from two dimensions of his work, distinct, though inseparable. The first one is suggested through the subject’s positive practical self-relation linked to the patterns of reciprocal recognition of love, right and social esteem; the second is formulated as non-centered autonomy opposed to the present-day criticism of the modern autonomous subject encompassing three levels, namely: the capacity of linguistic articulation, the narrative coherence of life and the complementation of being guided by principles with some criteria of moral sensitivity to the context. We defend the position that, by metaphysically anchoring the concept of autonomy onto the intersubjective assumptions of his/her theory of the subject, and exploring it linked to the subject’s positive practical self-relation and to a non-centered meaning, Honneth has managed to renew it, which allows drawing important consequences of such effort to the field of education.

    2017-06-01

    We present a new automated procedure that simultaneously derives the effective temperature Teff, surface gravity log g, metallicity [Fe/H], and equatorial projected rotational velocity ve sin i for stars. The procedure is inspired by the well-known PCA-based inversion of spectropolarimetric full-Stokes solar data, which was used both for Zeeman and Hanle effects. The efficiency and accuracy of this procedure have been proven for FGK, A, and late type dwarf stars of K and M spectral types. Learning databases are generated from the Elodie stellar spectra library using observed spectra for which fundamental parameters were already evaluated or with synthetic data. The synthetic spectra are calculated using ATLAS9 model atmospheres. This technique helped us to detect many peculiar stars such as Am, Ap, HgMn, SiEuCr and binaries. This fast and efficient technique could be used every time a pattern recognition is needed. One important application is the understanding of the physical properties of planetary surfaces by comparing aboard instrument data to synthetic ones.

    Human beings exploit emotions comprehensively for conveying messages and their resolution. Emotion detection and face recognition can provide an interface between the individuals and technologies. The most successful applications of recognition analysis are recognition of faces. Many different techniques have been used to recognize the facial expressions and emotion detection handle varying poses. In this paper, we approach an efficient method to recognize the facial expressions to track face points and distances. This can automatically identify observer face movements and face expression in image. This can capture different aspects of emotion and facial expressions.

    2017-11-07

    Iris recognition can be accomplished for a wide variety of eye images by using plenoptic imaging. Using plenoptic technology, it is possible to correct focus after image acquisition. One example technology reconstructs images having different focus depths and stitches them together, resulting in a fully focused image, even in an off-angle gaze scenario. Another example technology determines three-dimensional data for an eye and incorporates it into an eye model used for iris recognition processing. Another example technology detects contact lenses. Application of the technologies can result in improved iris recognition under a wide variety of scenarios.

    A fundamental problem with nearly all work in music genre recognition (MGR)is that evaluation lacks validity with respect to the principal goals of MGR. This problem also occurs in the evaluation of music emotion recognition (MER). Standard approaches to evaluation, though easy to implement, do not reliably differentiate between recognizing genre or emotion from music, or by virtue of confounding factors in signals (e.g., equalization). We demonstrate such problems for evaluating an MER syste...

  12. Trauma Symptoms in Abused Children

    Parvaneh Mohammadkhani

    2003-07-01

    Full Text Available Objective: There are many traumatic events (including natural disasters, physical, psychological and sexual abuse that may befall children and there is clear evidence that such experiences can produce a plethora of negative psychological effects. Children’s exposure to such traumas has been associated with a wide variety of negative mental health outcomes, including anxiety and depression, post-traumatic stress and dissociation and anger and aggression. It seems that the impacts of traumatic events are significantly related to type and intensity of trauma. Materials & Method: Through a systematized clustral sampling 3042 male and female students from junior high school who were participated in a survey study for investigating point prevalence of child abuse, completed Trauma Symptoms Checklist for Children-Alternate Version (TSCC-A and Child Abuse Self-report Scale (CASRS. After recognition of abused children, they were compared based on trauma symptoms. TSCC-A is a self-report measure of post-traumatic distress and related psychological symptomatology in male and female children aged 8-16 years. It is useful in the evaluation of children who have experienced traumatic events, including physical and sexual assault, victimization by peers, major losses, the witnessing of violence done to others and natural disasters. TSCC-A makes no reference to sexual issues. CASRS is a self-report scale to assess child abuse and neglect with 38 items and four subscales (psychological abuse, neglect, physical and sexual abuse. Results: Considering the type of traumatic experiences, the results showed that abused children significantly received higher scores in scales and subscales of TSCC-A than nonabused group. They specially reported more symptoms (depression, anxiety, post-traumatic stress, anger and dissociation comparing normal children. Conclusion: It is concluded that the type and rate of traumatic event is related to intensity of symptomatology.

  13. A reciprocal model of face recognition and autistic traits: evidence from an individual differences perspective.

    Drew W R Halliday

    Full Text Available Although not a core symptom of the disorder, individuals with autism often exhibit selective impairments in their face processing abilities. Importantly, the reciprocal connection between autistic traits and face perception has rarely been examined within the typically developing population. In this study, university participants from the social sciences, physical sciences, and humanities completed a battery of measures that assessed face, object and emotion recognition abilities, general perceptual-cognitive style, and sub-clinical autistic traits (the Autism Quotient (AQ. We employed separate hierarchical multiple regression analyses to evaluate which factors could predict face recognition scores and AQ scores. Gender, object recognition performance, and AQ scores predicted face recognition behaviour. Specifically, males, individuals with more autistic traits, and those with lower object recognition scores performed more poorly on the face recognition test. Conversely, university major, gender and face recognition performance reliably predicted AQ scores. Science majors, males, and individuals with poor face recognition skills showed more autistic-like traits. These results suggest that the broader autism phenotype is associated with lower face recognition abilities, even among typically developing individuals.

    2017-07-01

    With the progress of smartphones hardware, it is simple on smartphone using image recognition technique such as face detection. In addition, indoor navigation system development is much slower than outdoor navigation system. Hence, this research proves a usage of image recognition technique for navigation in indoor environment. In this paper, we introduced an indoor navigation application that uses the indoor environment features to locate user's location and a route calculating algorithm to generate an appropriate path for user. The application is implemented on Android smartphone rather than iPhone. Yet, the application design can also be applied on iOS because the design is implemented without using special features only for Android. We found that digital navigation system provides better and clearer location information than paper map. Also, the indoor environment is ideal for Image recognition processing. Hence, the results motivate us to design an indoor navigation system using image recognition.

  17. Similarity measures for face recognition

    CERN Document Server

    Vezzetti, Enrico

    2015-01-01

    Face recognition has several applications, including security, such as (authentication and identification of device users and criminal suspects), and in medicine (corrective surgery and diagnosis). Facial recognition programs rely on algorithms that can compare and compute the similarity between two sets of images. This eBook explains some of the similarity measures used in facial recognition systems in a single volume. Readers will learn about various measures including Minkowski distances, Mahalanobis distances, Hansdorff distances, cosine-based distances, among other methods. The book also summarizes errors that may occur in face recognition methods. Computer scientists "facing face" and looking to select and test different methods of computing similarities will benefit from this book. The book is also useful tool for students undertaking computer vision courses.

    Face recognition is one of the most important tasks in computer vision and pattern recognition. Face recognition is useful for security systems to provide safety. In some situations it is necessary to identify the person among many others. In this case this work presents new approach in data indexing, which provides fast retrieval in big image collections. Data indexing in this research consists of five steps. First, we detect the area containing face, second we align face, and then we detect areas containing eyes and eyebrows, nose, mouth. After that we find key points of each area using different descriptors and finally index these descriptors with help of quantization procedure. The experimental analysis of this method is performed. This paper shows that performing method has results at the level of state-of-the-art face recognition methods, but it is also gives results fast that is important for the systems that provide safety.

    Campeanu, Sandra; Craik, Fergus I M; Alain, Claude

    2013-01-01

    Behavioral studies of spoken word memory have shown that context congruency facilitates both word and source recognition, though the level at which context exerts its influence remains equivocal. We measured event-related potentials (ERPs) while participants performed both types of recognition task with words spoken in four voices. Two voice parameters (i.e., gender and accent) varied between speakers, with the possibility that none, one or two of these parameters was congruent between study and test. Results indicated that reinstating the study voice at test facilitated both word and source recognition, compared to similar or no context congruency at test. Behavioral effects were paralleled by two ERP modulations. First, in the word recognition test, the left parietal old/new effect showed a positive deflection reflective of context congruency between study and test words. Namely, the same speaker condition provided the most positive deflection of all correctly identified old words. In the source recognition test, a right frontal positivity was found for the same speaker condition compared to the different speaker conditions, regardless of response success. Taken together, the results of this study suggest that the benefit of context congruency is reflected behaviorally and in ERP modulations traditionally associated with recognition memory.

    Full Text Available Based on pattern recognition method, applied the nuclear radiation digital measurement and analysis system platform, through synthetically making use of the radioactive nuclide’s ray information, selected radiation characteristic information of the radioactive nuclide, established the characteristic arrays database of radioactive nuclides, the recognition method is designed and applied to the identification of radionuclide radiation while using middle or low-resolution detector in this paper. Verified by experiments, when the count value of the traditional low-resolution spectrometer system is not reach single full energy peak’s statistical lower limit value, the three kinds of mixed radioactive nuclides’ true discrimination rate reached more than 90 % in the digital measurement and analysis system using fast radionuclide recognition method. The results show that this method is obviously superior to the traditional methods, and effectively improve the rapid identification ability to radioactive nuclide.

    Objective: To determine the prodromal symptoms of schizophrenia in the pathways to help-seeking. Study Design: A cross-sectional study. Place and Duration of Study: The Department of Psychiatry, the Aga Khan University, Karachi, from 2008 to 2009. Methodology: A total of 93 patients were interviewed in the pathways to care of schizophrenia. The diagnosis was based on ICD-10 criteria. The pathways to care were assessed through a semi-structured questionnaire. The onset, course and symptoms of psychosis were assessed through Interview for Retrospective Assessment at Age at Onset of Psychosis (IROAS). Results: Fifty five (59%) participants were male while 41% (n=38%) were female. Using IROAS, 108 symptoms were identified as concerning behaviour. Alternatively, 60 (55%) concerning behaviours were reported in the open-ended inquiry of the reasons for help seeking as assessed by the pathways to care questionnaire with a statistically significant difference between most symptoms category. The difference was most pronounced (p < 0.001) for depressed mood (66%), worries (65%), tension (63%), withdrawal/mistrust (54%) and loss of self-confidence (53%). Thought withdrawal (22%) and passivity (15%) were elicited only through structured interview (IROAS). When symptoms were categorized together, about 83% of the subjects presented with affective and non-specific prodromal symptoms. Roughly, 10% of the subjects presented with positive symptoms and 3% presented with the negative symptoms of psychosis. The non-specific, affective symptoms appear to predominate the prodromal phase of the illness. Conclusion: Prodromal symptoms of schizophrenia include non-specific, affective symptoms. Attention needs to be paid on identifying the prodromal symptoms and change in social functioning in order to identify those who are at risk of long term psychosis. (author)

  9. State of the Science in Heart Failure Symptom Perception Research: An Integrative Review.

    Science.gov (United States)

    Lee, Solim; Riegel, Barbara

    Heart failure (HF) is a common condition requiring self-care to maintain physical stability, prevent hospitalization, and improve quality of life. Symptom perception, a domain of HF self-care newly added to the Situation-Specific Theory of HF Self-Care, is defined as a comprehensive process of monitoring and recognizing physical sensations and interpreting and labeling the meaning of the sensations. The purpose of this integrative review was to describe the research conducted on HF symptom perception to further understanding of this new concept. A literature search was conducted using 8 databases. The search term of HF was combined with symptom, plus symptom perception subconcepts of monitoring, somatic awareness, detection, recognition, interpretation, and appraisal. Only peer-reviewed original articles published in English with full-text availability were included. No historical limits were imposed. Study subjects were adults. Twenty-one studies met the inclusion criteria. Each study was categorized into either symptom monitoring or symptom recognition and interpretation. Although daily weighing and HF-related symptom-monitoring behaviors were insufficient in HF patients, use of a symptom diary improved HF self-care, symptom distress and functional class, and decreased mortality, hospital stay, and medical costs. Most HF patients had trouble recognizing an exacerbation of symptoms. Aging, comorbid conditions, and gradual symptom progression made it difficult to recognize and correctly interpret a symptom exacerbation. Living with others, higher education, higher uncertainty, shorter symptom duration, worse functional class, and an increased number of previous hospitalizations were positively associated with symptom recognition. Existing research fails to capture all of the elements in the theoretical definition of symptom perception.

  12. [Negative symptoms, emotion and cognition in schizophrenia].

    For a long time, treatment of schizophrenia has been essentially focussed on positive symptoms managing. Yet, even if these symptoms are the most noticeable, negative symptoms are more enduring, resistant to pharmacological treatment and associated with a worse prognosis. In the two last decades, attention has shift towards cognitive deficit, as this deficit is most robustly associated to functional outcome. But it appears that the modest improvement in cognition, obtained in schizophrenia through pharmacological treatment or, more purposely, by cognitive enhancement therapy, has only lead to limited amelioration of functional outcome. Authors have claimed that pure cognitive processes, such as those evaluated and trained in lots of these programs, may be too distant from real-life conditions, as the latter are largely based on social interactions. Consequently, the field of social cognition, at the interface of cognition and emotion, has emerged. In a first part of this article we examined the links, in schizophrenia, between negative symptoms, cognition and emotions from a therapeutic standpoint. Nonetheless, investigation of emotion in schizophrenia may also hold relevant premises for understanding the physiopathology of this disorder. In a second part, we propose to illustrate this research by relying on the heuristic value of an elementary marker of social cognition, facial affect recognition. Facial affect recognition has been repeatedly reported to be impaired in schizophrenia and some authors have argued that this deficit could constitute an endophenotype of the illness. We here examined how facial affect processing has been used to explore broader emotion dysfunction in schizophrenia, through behavioural and imaging studies. In particular, fMRI paradigms using facial affect have shown particular patterns of amygdala engagement in schizophrenia, suggesting an intact potential to elicit the limbic system which may however not be advantageous. Finally, we

    Face recognition is image processing technique which aims to identify human faces and found its use in various different fields for example in security. Throughout the years this field evolved and there are many approaches and many different algorithms which aim to make the face recognition as effective...... as possible. The use of different approaches such as neural networks and machine learning can lead to fast and efficient solutions however, these solutions are expensive in terms of hardware resources and power consumption. A possible solution to this problem can be use of approximate arithmetic. In many image...... processing applications the results do not need to be completely precise and use of the approximate arithmetic can lead to reduction in terms of delay, space and power consumption.

    Mandarin Chinese is the official language in China and Taiwan, it is the native language of a quarter of the world population. As the services enabled by speech recognition technology (e.g. telephone voice dialing, information query) become more popular in English, we would like to extend this capability to other languages. Mandarin is one of the major languages under research in our laboratory. This paper describes how we extend our work in English speech recognition into Mandarin. We will described the corpus: Voice Across Taiwan, the training of a complete set of Mandarin syllable models, preliminary performance results and error analysis. A fast prototyping system was built, where a user can write any context free grammar with no restriction of vocabulary, then the grammar can be compiled into recognition models. It enables user to quickly test the performance of a new vocabulary.

  4. Familiar Person Recognition: Is Autonoetic Consciousness More Likely to Accompany Face Recognition Than Voice Recognition?

    Science.gov (United States)

    Barsics, Catherine; Brédart, Serge

    2010-11-01

    Autonoetic consciousness is a fundamental property of human memory, enabling us to experience mental time travel, to recollect past events with a feeling of self-involvement, and to project ourselves in the future. Autonoetic consciousness is a characteristic of episodic memory. By contrast, awareness of the past associated with a mere feeling of familiarity or knowing relies on noetic consciousness, depending on semantic memory integrity. Present research was aimed at evaluating whether conscious recollection of episodic memories is more likely to occur following the recognition of a familiar face than following the recognition of a familiar voice. Recall of semantic information (biographical information) was also assessed. Previous studies that investigated the recall of biographical information following person recognition used faces and voices of famous people as stimuli. In this study, the participants were presented with personally familiar people's voices and faces, thus avoiding the presence of identity cues in the spoken extracts and allowing a stricter control of frequency exposure with both types of stimuli (voices and faces). In the present study, the rate of retrieved episodic memories, associated with autonoetic awareness, was significantly higher from familiar faces than familiar voices even though the level of overall recognition was similar for both these stimuli domains. The same pattern was observed regarding semantic information retrieval. These results and their implications for current Interactive Activation and Competition person recognition models are discussed.

    The recognition and management of transfusion reactions (TRs) are critical to ensure patient safety during and after a blood transfusion. Transfusion reactions are classified into acute transfusion reactions (ATRs) or delayed transfusion reactions, and each category includes different subtypes. Different ATRs share common signs and symptoms which can make categorisation difficult at the beginning of the reaction. Moreover, TRs are often under-recognised and under-reported. To ensure uniform practice and safety, it is necessary to implement a national haemovigilance system and a set of national guidelines establishing policies for blood transfusion and for the detection and management of TRs. In Oman, there are currently no local TR guidelines to guide physicians and hospital blood banks. This paper summarises the available literature and provides consensus guidelines to be used in the recognition, management and reporting of ATRs. PMID:25097764

  7. Alexithymia, not autism, predicts poor recognition of emotional facial expressions.

    Cook, Richard; Brewer, Rebecca; Shah, Punit; Bird, Geoffrey

    2013-05-01

    Despite considerable research into whether face perception is impaired in autistic individuals, clear answers have proved elusive. In the present study, we sought to determine whether co-occurring alexithymia (characterized by difficulties interpreting emotional states) may be responsible for face-perception deficits previously attributed to autism. Two experiments were conducted using psychophysical procedures to determine the relative contributions of alexithymia and autism to identity and expression recognition. Experiment 1 showed that alexithymia correlates strongly with the precision of expression attributions, whereas autism severity was unrelated to expression-recognition ability. Experiment 2 confirmed that alexithymia is not associated with impaired ability to detect expression variation; instead, results suggested that alexithymia is associated with difficulties interpreting intact sensory descriptions. Neither alexithymia nor autism was associated with biased or imprecise identity attributions. These findings accord with the hypothesis that the emotional symptoms of autism are in fact due to co-occurring alexithymia and that existing diagnostic criteria may need to be revised.

  8. Childhood constipation: recognition, management and the role of the nurse.

    2016-12-08

    Constipation is a common childhood condition that health professionals will encounter in many different settings. The majority of these cases of childhood constipation are idiopathic in nature. It is considered to exhibit the 'tip of the iceberg' phenomenon as a large number of cases remain undetected due to under-recognition by families, embarrassment regarding the condition, fear of receiving a negative response from health professionals, or parental belief there is actually something more seriously wrong and failure to accept the diagnosis. Prompt evaluation and management is likely to be associated with better outcomes. To ensure this, fast recognition of symptoms, with care taken to exclude any 'red flag' symptoms that could indicate an organic cause and subsequently a different treatment pathway, is essential. Nurses, given their regular contact with families in different settings, are suitably placed to detect these symptoms early and can play a vital role in successful management of the condition. Laxatives are the first line in management of constipation. Polyethylene glycol 3350 is the laxative that evidence-based guidelines from the National Institute for Health and Care Excellence (2010) recommend as the initial pharmacological management. Advice should also be given about supportive measures, including diet and lifestyle changes.

    2010-01-01

    Full Text Available Pain is a complex physiological phenomenon, it is hard to define in a satisfactory manner in human beings, and it is extremely difficult to recognize and interpret in animals. According to the International Association for the Study of Pain (IASP, pain is defined as an unpleasant sensory or emotional experience associated with actual or potential tissue damage. Pain is an important aspect of life and its prevention and decrease are important as a goal to achieve the well-being of animals. The task of scientists is to recognize the language of pain interpretation which animals use to seek help. For an objective evaluation of pain, it is essential to possess a good knowledge of physiology, etiology and clinical diagnosis. We are obliged to do this also because of the ethic principles to defend the well-being of animals and to eliminate any factor which can cause feelings of pain or suffering. The recognition of pain and its manifestation is especially important in cases of animal abuse, when it could be the only symptom. Animals can be quiet and instinctively hide the presence of pain, which makes the symptoms more subtle, but does not make their injuries any less painful. It is also important to have knowledge of manifestations of pain that appear during different surgical procedures performed by the veterinarinarian in spite of the applied dose of analgetic. Pain significantly contributes to the suffering of animals and in such cases it is important to collect relevant documents, in the form of video recordings or in photodocumentation form, because it is important information in the processing of cases of animal abuse. Veterinary experts have the responsibility to recognize, evaluate, and prevent pain and to relieve animals from the pain, which should be the fourth vital sign, following temperature, pulse and breathing, and participate in the evaluation of the condition of the animal during an examination. Due to all the above mentioned, it is

    2013-01-01

    Full Text Available This paper addresses the recognition of large-scale outdoor scenes on smartphones by fusing outputs of inertial sensors and computer vision techniques. The main contributions can be summarized as follows. Firstly, we propose an ORD (overlap region divide method to plot image position area, which is fast enough to find the nearest visiting area and can also reduce the search range compared with the traditional approaches. Secondly, the vocabulary tree-based approach is improved by introducing GAGCC (gravity-aligned geometric consistency constraint. Our method involves no operation in the high-dimensional feature space and does not assume a global transform between a pair of images. Thus, it substantially reduces the computational complexity and memory usage, which makes the city scale image recognition feasible on the smartphone. Experiments on a collected database including 0.16 million images show that the proposed method demonstrates excellent recognition performance, while maintaining the average recognition time about 1 s.

    Abaza, Ayman; Harrison, Mary Ann F.

    2013-05-01

    Ear Recognition has recently received significant attention in the literature. Even though current ear recognition systems have reached a certain level of maturity, their success is still limited. This paper presents an efficient complete ear-based biometric system that can process five frames/sec; Hence it can be used for surveillance applications. The ear detection is achieved using Haar features arranged in a cascaded Adaboost classifier. The feature extraction is based on dividing the ear image into several blocks from which Local Binary Pattern feature distributions are extracted. These feature distributions are then fused at the feature level to represent the original ear texture in the classification stage. The contribution of this paper is three fold: (i) Applying a new technique for ear feature extraction, and studying various optimization parameters for that technique; (ii) Presenting a practical ear recognition system and a detailed analysis about error propagation in that system; (iii) Studying the occlusion effect of several ear parts. Detailed experiments show that the proposed ear recognition system achieved better performance (94:34%) compared to other shape-based systems as Scale-invariant feature transform (67:92%). The proposed approach can also handle efficiently hair occlusion. Experimental results show that the proposed system can achieve about (78%) rank-1 identification, even in presence of 60% occlusion.

    An association between fibromyalgia and hepatitis C virus (HCV) has been previously described. However, the relationship between nonalcoholic steatohepatitis (NASH) and fibromyalgia symptoms has not been assessed, though they share several risk factors. We aimed to assess the factors associated with fibromyalgia symptoms across etiologies of liver disease. Patients with cirrhosis due to HCV, NASH, or alcohol were recruited from an outpatient hepatology clinic and administered the Hospital Anxiety and Depression Score, Pittsburgh Sleep Quality Index, and the modified 2010 American College of Rheumatology Diagnostic Criteria for Fibromyalgia. Serum inflammatory markers were measured with standard luminex assays. Of 193 participants, 53 (27 %) met criteria for fibromyalgia. Fibromyalgia symptoms were significantly associated with etiology of liver disease (HCV: 35 %, NASH: 30 %, alcohol-related liver disease: 12 %, p etiology of liver disease (NASH vs. HCV not different, alcohol vs. HCV OR 0.19, 95 % CI 0.05, 0.63) were associated with fibromyalgia symptoms. If abdominal pain was included in the model, etiology became nonsignificant, indicating that it may be central sensitization due to abdominal pain in patients with chronic liver disease that explains fibromyalgia symptoms rather than the etiology of liver disease or inflammation. Fibromyalgia symptoms were significantly associated with HCV and NASH cirrhosis and with psychiatric symptoms. Future work should focus on the underlying pathophysiology and management of widespread pain in patients with cirrhosis.

  8. Cocaine and Psychiatric Symptoms.

    Science.gov (United States)

    Morton, W Alexander

    1999-08-01

    BACKGROUND: Cocaine is an addictive drug that produces numerous psychiatric symptoms, syndromes, and disorders. The symptoms include agitation, paranoia, hallucinations, delusions, violence, as well as suicidal and homicidal thinking. They can be primary to the drug's effect or secondary to exacerbation of comorbid psychiatric disorders. DATA SOURCES: A computerized literature search was conducted using MEDLINE to identify reports of psychiatric symptoms secondary to cocaine use. Additional reports were found via bibliographies of various published reports. DATA SYNTHESIS: The use of cocaine in the "crack" form is often associated with more frequent and intense symptoms. Paranoia occurs in 68% to 84% of patients using cocaine. Cocaine-related violent behaviors occur in as many as 55% of patients with cocaine-induced psychiatric symptoms. Homicide has also been associated with cocaine use in as many as 31% of homicide victims. In suicide, cocaine has been found to be present in as high as 18% to 22% of cases. Many patients with cocaine dependence have also been found to have a comorbid psychiatric disorder. CONCLUSION: Cocaine can produce a spectrum of psychiatric symptoms with which primary care practitioners need to be familiar. Comorbid psychiatric disorders are frequent in patients with cocaine use disorders and can worsen with cocaine use. Nonaddictive medication may be necessary to treat comorbid conditions such as anxiety and depressive disorders. Primary care practitioners need to be familiar with the treatment programs for patients with cocaine use disorders so appropriate referral can easily take place and follow-up care can be understood and maintained.

  9. Recognition of human oncogenic viruses by host pattern recognition receptors

    Full Text Available Human oncogenic viruses include Epstein-Barr virus (EBV, hepatitis B virus (HBV, hepatitis C virus (HCV, human papilloma virus (HPV, human T-cell lymphotropic virus (HTLV-1, Kaposi’s associated sarcoma virus (KSHV, and Merkel cell polyomavirus (MCPyV. It would be expected that during virus-host interaction, the immune system would recognize these pathogens and eliminate them. However, through evolution, these viruses have developed a number of strategies to avoid such an outcome and successfully establish chronic infections. The persistent nature of the infection caused by these viruses is associated with their oncogenic potential. In this article, we will review the latest information on the interaction between oncogenic viruses and the innate immune system of the host. In particular, we will summarize the available knowledge on the recognition by host pattern-recognition receptors (PRRs of pathogen-associated molecular patterns (PAMPs present in the incoming viral particle or generated during the virus’ life cycle. We will also review the data on the recognition of cell-derived danger associated molecular patterns (DAMPs generated during the virus infection that may impact the outcome of the host-pathogen interaction and the development cancer.

  10. Embedded Face Detection and Recognition

    Directory of Open Access Journals (Sweden)

    2012-10-01

    Full Text Available The need to increase security in open or public spaces has in turn given rise to the requirement to monitor these spaces and analyse those images on-site and on-time. At this point, the use of smart cameras – of which the popularity has been increasing – is one step ahead. With sensors and Digital Signal Processors (DSPs, smart cameras generate ad hoc results by analysing the numeric images transmitted from the sensor by means of a variety of image-processing algorithms. Since the images are not transmitted to a distance processing unit but rather are processed inside the camera, it does not necessitate high-bandwidth networks or high processor powered systems; it can instantaneously decide on the required access. Nonetheless, on account of restricted memory, processing power and overall power, image processing algorithms need to be developed and optimized for embedded processors. Among these algorithms, one of the most important is for face detection and recognition. A number of face detection and recognition methods have been proposed recently and many of these methods have been tested on general-purpose processors. In smart cameras – which are real-life applications of such methods – the widest use is on DSPs. In the present study, the Viola-Jones face detection method – which was reported to run faster on PCs – was optimized for DSPs; the face recognition method was combined with the developed sub-region and mask-based DCT (Discrete Cosine Transform. As the employed DSP is a fixed-point processor, the processes were performed with integers insofar as it was possible. To enable face recognition, the image was divided into sub-regions and from each sub-region the robust coefficients against disruptive elements – like face expression, illumination, etc. – were selected as the features. The discrimination of the selected features was enhanced via LDA (Linear Discriminant Analysis and then employed for recognition. Thanks to its

  12. Physical model for recognition tunneling

    International Nuclear Information System (INIS)

    Krstić, Predrag; Ashcroft, Brian; Lindsay, Stuart

    2015-01-01

    Recognition tunneling (RT) identifies target molecules trapped between tunneling electrodes functionalized with recognition molecules that serve as specific chemical linkages between the metal electrodes and the trapped target molecule. Possible applications include single molecule DNA and protein sequencing. This paper addresses several fundamental aspects of RT by multiscale theory, applying both all-atom and coarse-grained DNA models: (1) we show that the magnitude of the observed currents are consistent with the results of non-equilibrium Green’s function calculations carried out on a solvated all-atom model. (2) Brownian fluctuations in hydrogen bond-lengths lead to current spikes that are similar to what is observed experimentally. (3) The frequency characteristics of these fluctuations can be used to identify the trapped molecules with a machine-learning algorithm, giving a theoretical underpinning to this new method of identifying single molecule signals.

    2017-12-01

    Molecular recognition is central to biological processes, function, and specificity. Proteins associate with ligands with a wide range of association rate constants, with maximal values matching the theoretical limit set by the rate of diffusional collision. As less is known about RNA association, we compiled association rate constants for all RNA/ligand complexes that we could find in the literature. Like proteins, RNAs exhibit a wide range of association rate constants. However, the fastest RNA association rates are considerably slower than those of the fastest protein associations and fall well below the diffusional limit. The apparently general observation of slow association with RNAs has implications for evolution and for modern-day biology. Our compilation highlights a quantitative molecular property that can contribute to biological understanding and underscores our need to develop a deeper physical understanding of molecular recognition events. © 2017 Gleitsman et al.; Published by Cold Spring Harbor Laboratory Press for the RNA Society.

    The increase in traffic accidents is becoming a serious social problem with the recent rapid traffic increase. In many cases, the driver"s carelessness is the primary factor of traffic accidents, and the driver assistance system is demanded for supporting driver"s safety. In this research, we propose the new method of automatic detection and recognition of road signs by image processing. The purpose of this research is to prevent accidents caused by driver"s carelessness, and call attention to a driver when the driver violates traffic a regulation. In this research, high accuracy and the efficient sign detecting method are realized by removing unnecessary information except for a road sign from an image, and detect a road sign using shape features. At first, the color information that is not used in road signs is removed from an image. Next, edges except for circular and triangle ones are removed to choose sign shape. In the recognition process, normalized cross correlation operation is carried out to the two-dimensional differentiation pattern of a sign, and the accurate and efficient method for detecting the road sign is realized. Moreover, the real-time operation in a software base was realized by holding down calculation cost, maintaining highly precise sign detection and recognition. Specifically, it becomes specifically possible to process by 0.1 sec(s)/frame using a general-purpose PC (CPU: Pentium4 1.7GHz). As a result of in-vehicle experimentation, our system could process on real time and has confirmed that detection and recognition of a sign could be performed correctly.

  18. Thermal to visible face recognition

    2012-06-01

    In low light conditions, visible light face identification is infeasible due to the lack of illumination. For nighttime surveillance, thermal imaging is commonly used because of the intrinsic emissivity of thermal radiation from the human body. However, matching thermal images of faces acquired at nighttime to the predominantly visible light face imagery in existing government databases and watch lists is a challenging task. The difficulty arises from the significant difference between the face's thermal signature and its visible signature (i.e. the modality gap). To match the thermal face to the visible face acquired by the two different modalities, we applied face recognition algorithms that reduce the modality gap in each step of face identification, from low-level analysis to machine learning techniques. Specifically, partial least squares-discriminant analysis (PLS-DA) based approaches were used to correlate the thermal face signatures to the visible face signatures, yielding a thermal-to-visible face identification rate of 49.9%. While this work makes progress for thermal-to-visible face recognition, more efforts need to be devoted to solving this difficult task. Successful development of a thermal-to-visible face recognition system would significantly enhance the Nation's nighttime surveillance capabilities.

    Full Text Available Faces are highly challenging and dynamic objects that are employed as biometrics evidence in identity verification. Recently, biometrics systems have proven to be an essential security tools, in which bulk matching of enrolled people and watch lists is performed every day. To facilitate this process, organizations with large computing facilities need to maintain these facilities. To minimize the burden of maintaining these costly facilities for enrollment and recognition, multinational companies can transfer this responsibility to third-party vendors who can maintain cloud computing infrastructures for recognition. In this paper, we showcase cloud computing-enabled face recognition, which utilizes PCA-characterized face instances and reduces the number of invariant SIFT points that are extracted from each face. To achieve high interclass and low intraclass variances, a set of six PCA-characterized face instances is computed on columns of each face image by varying the number of principal components. Extracted SIFT keypoints are fused using sum and max fusion rules. A novel cohort selection technique is applied to increase the total performance. The proposed protomodel is tested on BioID and FEI face databases, and the efficacy of the system is proven based on the obtained results. We also compare the proposed method with other well-known methods.

    The interaction of transcription factors with specific DNA sites is key for the regulation of gene expression. Despite the availability of a large body of structural data on protein-DNA complexes, we are still far from fully understanding the molecular and biophysical bases underlying such interactions. Therefore, the development of non-natural agents that can reproduce the DNA-recognition properties of natural transcription factors remains a major and challenging goal in chemical biology. In this review we summarize the basics of double-stranded DNA recognition by transcription factors, and describe recent developments in the design and preparation of synthetic DNA binders. We mainly focus on synthetic peptides that have been designed by following the DNA interaction of natural proteins, and we discuss how the tools of organic synthesis can be used to make artificial constructs equipped with functionalities that introduce additional properties to the recognition process, such as sensing and controllability.

    2011-06-01

    Finger Print Recognition is concerned with the difficult task of matching the images of finger print of a person with the finger print present in the database efficiently. Finger print Recognition is used in forensic science which helps in finding the criminals and also used in authentication of a particular person. Since, Finger print is the only thing which is unique among the people and changes from person to person. The present paper describes finger print recognition methods using various edge detection techniques and also how to detect correct finger print using a camera images. The present paper describes the method that does not require a special device but a simple camera can be used for its processes. Hence, the describe technique can also be using in a simple camera mobile phone. The various factors affecting the process will be poor illumination, noise disturbance, viewpoint-dependence, Climate factors, and Imaging conditions. The described factor has to be considered so we have to perform various image enhancement techniques so as to increase the quality and remove noise disturbance of image. The present paper describe the technique of using contour tracking on the finger print image then using edge detection on the contour and after that matching the edges inside the contour.

    2010-02-01

    In current study we examine how letter permutation affects in visual recognition of words for two orthographically dissimilar languages, Urdu and German. We present the hypothesis that recognition or reading of permuted and non-permuted words are two distinct mental level processes, and that people use different strategies in handling permuted words as compared to normal words. A comparison between reading behavior of people in these languages is also presented. We present our study in context of dual route theories of reading and it is observed that the dual-route theory is consistent with explanation of our hypothesis of distinction in underlying cognitive behavior for reading permuted and non-permuted words. We conducted three experiments in lexical decision tasks to analyze how reading is degraded or affected by letter permutation. We performed analysis of variance (ANOVA), distribution free rank test, and t-test to determine the significance differences in response time latencies for two classes of data. Results showed that the recognition accuracy for permuted words is decreased 31% in case of Urdu and 11% in case of German language. We also found a considerable difference in reading behavior for cursive and alphabetic languages and it is observed that reading of Urdu is comparatively slower than reading of German due to characteristics of cursive script.

    2004-02-01

    A relationship among air quality, respiratory health, and comfort in man and animal is widely shown. In general, a state of respiratory discomfort is prevailed by an increase in acoustic audible symptoms. The general concept of sound analysis as an objective contactless non-invasive biomarker for aerial pollution is studied on free-field cough sound of 12 Belgian Landrace piglets. A citric-acid-induced cough sound recognition algorithm with recognition rate of 95% is applied to cough sounds registered in the presence of distinct types of aerial pollutants: irritating gas (ammonia), respirable particles (dust), and temperature. The recognition performance for all aerial pollutants was >90% and maintained 94% on average. It is concluded that sound analysis allows an effective biomarker for all three types of aerial pollution. The generality of the biomarker is hypothesized to be due to the common mechanism involved in protective cough. As a consequence, it is suggested to use sound analysis as a biomarker for respiratory state in studies of exposure to air pollutants.

  4. Management of Menopausal Symptoms

    2015-01-01

    Most menopausal women experience vasomotor symptoms, with bothersome symptoms often lasting longer than one decade. Hormone therapy (HT) represents the most effective treatment for these symptoms, with oral and transdermal estrogen formulations having comparable efficacy. Findings from the Women’s Health Initiative and other recent randomized clinical trials have helped to clarify the benefits and risks of combination estrogen-progestin and estrogen-alone therapy. Absolute risks observed with HT tended to be small, especially in younger women. Neither regimen affected all-cause mortality rates. Given the lower rates of adverse events on HT among women close to menopause onset and at lower baseline risk of cardiovascular disease, risk stratification and personalized risk assessment appears to represent a sound strategy for optimizing the benefit: risk profile and safety of hormone therapy. Systemic HT should not be arbitrarily stopped at age 65; instead treatment duration should be individualized based on patients’ risk profiles and personal preferences. Genitourinary syndrome of menopause represents a common condition that adversely impacts the quality of life of many menopausal women. Without treatment, symptoms worsen over time. Low-dose vaginal estrogen represents highly effective treatment for this condition. Because custom-compounded hormones have not been tested for efficacy or safety, U.S. Food and Drug Administration (FDA)-approved HT is preferred. A low dose formulation of paroxetine mesylate currently represents the only nonhormonal medication FDA-approved to treat vasomotor symptoms. Gynecologists and other clinicians who remain abreast of data addressing the benefit: risk profile of hormonal and nonhormonal treatments can help menopausal women make sound choices regarding management of menopausal symptoms.

    2016-01-01

    Cognitive impairments associated with schizophrenia are very frequent. They concern both neurocognition and social cognition, including facial emotion recognition. These impairments have a negative impact on the daily functioning, in particular the social and vocational rehabilitation of people with schizophrenia. Previous studies in this area clearly demonstrated the interest of cognitive remediation to improve neurocognitive and social cognitive functioning in schizophrenia. They also established clear links between facial emotion recognition skills and attentional processes. The present study compares the GAÏA s-face program (GAÏA arm), which focuses on facial emotion recognition processes, with the RECOS program (RECOS arm), a neurocognitive remediation therapy focusing on selective attention. Forty people with schizophrenia were randomly distributed between each study arm and assessed pre- (T1) and post- (T2) therapy. The single-blind assessment focused on facial emotion recognition (the main criteria), symptoms, social and subjective functioning, and neurocognitive and social cognitive performance. Both programs were conducted by nurses after a 3-day training session. The study showed a significant improvement in facial emotion recognition performance in both groups, with a significantly larger effect in the GAÏA arm. Symptoms and social functioning also improved in the GAÏA arm, and certain neurocognitive and social cognitive processes improved in both study arms. Further studies are recommended, with larger population samples and a follow-up assessing the long-term preservation of these improvements.

    Full Text Available Objective: To analyze the recognition, identification, and discrimination of facial emotions in a sample of outpatients with bipolar disorder (BD. Methods: Forty-four outpatients with diagnosis of BD and 48 matched control subjects were selected. Both groups were assessed with tests for recognition (Emotion Recognition-40 - ER40, identification (Facial Emotion Identification Test - FEIT, and discrimination (Facial Emotion Discrimination Test - FEDT of facial emotions, as well as a theory of mind (ToM verbal test (Hinting Task. Differences between groups were analyzed, controlling the influence of mild depressive and manic symptoms. Results: Patients with BD scored significantly lower than controls on recognition (ER40, identification (FEIT, and discrimination (FEDT of emotions. Regarding the verbal measure of ToM, a lower score was also observed in patients compared to controls. Patients with mild syndromal depressive symptoms obtained outcomes similar to patients in euthymia. A significant correlation between FEDT scores and global functioning (measured by the Functioning Assessment Short Test, FAST was found. Conclusions: These results suggest that, even in euthymia, patients with BD experience deficits in recognition, identification, and discrimination of facial emotions, with potential functional implications.

    It is unknown what causes uraemic symptoms in renal disease. Chronic kidney disease (CKD) patients are known to have increased levels of urea, sodium, potassium and phosphate in their saliva compared with those without renal disease. The present cross-sectional study investigated associations between known genetic traits of taste and self-reported upper gastrointestinal (GI) symptoms experienced in CKD patients with the changes in saliva composition found in renal failure. Fifty-six CKD patients (35 males, 21 females, age 67±14 years), with stages 4 and 5 renal failure, selected from a tertiary hospital renal outpatient clinic participated in this study. Subjects answered a questionnaire to assess upper GI symptoms and tested for the genetic taste recognition thresholds of thiourea, phenylthiocarbamide and sodium benzoate. Saliva samples were collected to determine biochemical composition. Possible associations between genetic taste variations, saliva composition and upper GI symptoms were investigated. Of the 56 patients enroled, 29 (52%) reported major upper GI uraemic symptoms, whereas 27 (48%) had no symptoms or only minor complaints of dry mouth. There was a strong association between the symptomatic burden a patient experienced and the genetic ability to taste thiourea (Ptaste changes (Pgenetic ability to taste thiourea. This study provides evidence that the genetic ability to taste thiourea as bitter, in combination with the increase in active compounds found in CKD patient's saliva, impacts on the uraemic upper GI symptoms experienced.

    The aims of this cross-sectional study were to examine the association between significant ADHD symptoms and the four domains of anxiety symptoms on the Taiwanese version of Multidimensional Anxiety Scale for Children (MASC-T) and to examine the moderating effects of sociodemographic characteristics on this association among Taiwanese adolescents in the community. A total of 4,716 adolescents in Grades 7 through 12 in southern Taiwan completed the MASC-T, the ADHD Self-Rated Scale, the Mandarin Chinese version of the Center for Epidemiological Studies Depression Scale, the Rosenberg Self-Esteem Scale, and a questionnaire about sociodemographic characteristics. Multiple regression analysis was used to examine both the association of significant ADHD symptoms with four domains of anxiety symptoms on the MASC-T and the moderating effects of sociodemographic characteristics on this association. The adolescents with significant ADHD symptoms had more severe total anxiety symptoms, physical symptoms, social anxiety symptoms, and separation/panic symptoms for three domains of the MASC-T but less harm avoidance than did those without significant ADHD symptoms. Age, gender, and low self-esteem had moderating effects on the association between significant ADHD symptoms and anxiety symptoms for some domains of the MASC-T. The results of this study suggest a significant association between significant ADHD symptoms and the severity of anxiety symptoms in adolescents. Clinicians must evaluate anxiety symptoms among adolescents with ADHD and arrange comprehensive treatment programs. © 2012 SAGE Publications.

  14. Theodicies as Failures of Recognition

    Directory of Open Access Journals (Sweden)

    Sari Kivistö

    2017-11-01

    Full Text Available This paper examines the ethical failure of theodicies by integrating the perspectives of philosophical argumentation and literary reading and analysis. The paper consists of two main parts. In the first part, we propose an ethical critique of metaphysical realism by analyzing its inability to recognize the perspectival plurality and diversity of suffering. As theodicies seek to explain how an omnipotent, omniscient, and absolutely benevolent God could allow the world to contain evil and suffering, it can be argued that metaphysical realism—i.e., the thesis that the world possesses its own fundamental structure independently of human perspectives of conceptualization and inquiry—is a problematic starting point of theodicism. We examine the failure of recognition of others’ suffering inherent in theodicies as a failure based on the search for an overall reductive and objectifying picture (a “God’s-Eye View” that is constitutive of metaphysical realism. The second part of the paper shows why we should include insights from imaginative literature in our attempts to understand the recognition failures of theodicies. Emphasizing the literary, philosophical, and theological relevance of various modern rewritings of the Book of Job, which has been a crucially important sub-text for many later literary works in which the protagonists render a particular kind of human experience—unmerited suffering—we turn more closely to some literary examples, such as Joseph Roth’s novels Hiob and Die Rebellion. The tensions that are created around the moral controversy of the experiences of injustice and suffering and the human and religious reasoning and justification of violence are examined. The ambiguous ending of Hiob that adds an apparently hopeful and almost fairytale-like redemption to the story plays a crucial role in the interpretation provided in the paper. By analyzing some literary examples and their relation to the literary Job tradition

    Full Text Available An Elastic Bunch Graph Map (EBGM algorithm is being proposed in this research paper that successfully implements face recognition using Gabor filters. The proposed system applies 40 different Gabor filters on an image. As aresult of which 40 images with different angles and orientation are received. Next, maximum intensity points in each filtered image are calculated and mark them as Fiducial points. The system reduces these points in accordance to distance between them. The next step is calculating the distances between the reduced points using distance formula. At last, the distances are compared with database. If match occurs, it means that the image is recognized.

    Socio-emotional difficulties are thought to be important maintaining factors of eating disorders. Several studies point to deficits in facial affect recognition in anorexia nervosa (AN). However, the majority of these studies fail to control for comorbidity and its effect on emotional processing. This study aims to explore how patients with AN recognize happiness and sadness in human faces, controlling for different comorbidities, namely anxiety, depression, and obsessive-compulsive symptoms. Thirty patients with AN, and 40 healthy participants completed a facial emotion recognition task. This task measured discrimination accuracy, response bias and response time towards sad and happy faces presented at different durations (500 ms, 2000 ms). The associations between facial affect recognition and clinical symptoms and intelligence quotient were explored. Regression analysis showed that discrimination accuracy of sad faces presented for 500 ms was significantly associated with AN diagnosis, body mass index, and Obsessive-compulsive symptoms. However, the level of Obsessive-compulsive symptoms was the strongest predictor of a poor discrimination of briefly presented sad faces. Our results support previous studies that report emotional processing deficits in AN with obsessionality playing a pivotal role in this deficit.

    Document recognition advances have improved the lives of people with print disabilities, by providing accessible documents. This invited paper provides perspectives on the author's career progression from document recognition professional to social entrepreneur applying this technology to help people with disabilities. Starting with initial thoughts about optical character recognition in college, it continues with the creation of accurate omnifont character recognition that did not require training. It was difficult to make a reading machine for the blind in a commercial setting, which led to the creation of a nonprofit social enterprise to deliver these devices around the world. This network of people with disabilities scanning books drove the creation of Bookshare.org, an online library of scanned books. Looking forward, the needs for improved document recognition technology to further lower the barriers to reading are discussed. Document recognition professionals should be proud of the positive impact their work has had on some of society's most disadvantaged communities.

    Schulte-Körne, G; Deimel, W; Bartling, J; Remschmidt, H

    2004-07-01

    The neurobiological basis of learning word spellings and recognition of recently learned words was assessed in a learning experiment in 9 dyslexics and 9 controls male adolescents. In a recognition paradigm previously learned pseudowords and graphic symbols were presented 50 times each interspersed pseudo-randomly between 3 unlearned items which were repeated 50 times and 150 filler pseudowords. The electrophysiological correlate of recognition of learned pseudowords and graphic symbols was a positivity around 600 ms. For pseudowords the amplitude of this ERP component was significantly attenuated in the dyslexic group, no differences between the groups were found for recognition of graphic material. These data suggest that dyslexic children are able to learn the spelling of simple words, however, the neurophysiological correlate of recognition of these learned words is significantly attenuated. This result strengthens the view that dyslexic children are not generally impaired in recognition memory but specific for linguistic material like words.

    Mark Fišel

    2007-05-01

    Full Text Available This report addresses dialogue acts, their existing applications and techniques of automatically recognizing them, in Estonia as well as elsewhere. Three main applications are described: in dialogue systems to determine the intention of the speaker, in dialogue systems with machine translation to resolve ambiguities in the possible translation variants and in speech recognition to reduce word recognition error rate. Several recognition techniques are described on the surface level: how they work and how they are trained. A summary of the corresponding representation methods is provided for each technique. The paper also includes examples of applying the techniques to dialogue act recognition.The author comes to the conclusion that using the current evaluation metric it is impossible to compare dialogue act recognition techniques when these are applied to different dialogue act tag sets. Dialogue acts remain an open research area, with space and need for developing new recognition techniques and methods of evaluation.

    Handwriting recognition has been one of the active and challenging research areas in the field of pattern recognition. It has numerous applications which include, reading aid for blind, bank cheques and conversion of any hand written document into structural text form. As there is no sufficient number of works on Indian language character recognition especially Kannada script among 15 major scripts in India. In this paper an attempt is made to recognize handwritten Kannada characters using Feed Forward neural networks. A handwritten Kannada character is resized into 20x30 Pixel. The resized character is used for training the neural network. Once the training process is completed the same character is given as input to the neural network with different set of neurons in hidden layer and their recognition accuracy rate for different Kannada characters has been calculated and compared. The results show that the proposed system yields good recognition accuracy rates comparable to that of other handwritten character recognition systems.

  3. Dynamic Features for Iris Recognition.

    Science.gov (United States)

    da Costa, R M; Gonzaga, A

    2012-08-01

    The human eye is sensitive to visible light. Increasing illumination on the eye causes the pupil of the eye to contract, while decreasing illumination causes the pupil to dilate. Visible light causes specular reflections inside the iris ring. On the other hand, the human retina is less sensitive to near infra-red (NIR) radiation in the wavelength range from 800 nm to 1400 nm, but iris detail can still be imaged with NIR illumination. In order to measure the dynamic movement of the human pupil and iris while keeping the light-induced reflexes from affecting the quality of the digitalized image, this paper describes a device based on the consensual reflex. This biological phenomenon contracts and dilates the two pupils synchronously when illuminating one of the eyes by visible light. In this paper, we propose to capture images of the pupil of one eye using NIR illumination while illuminating the other eye using a visible-light pulse. This new approach extracts iris features called "dynamic features (DFs)." This innovative methodology proposes the extraction of information about the way the human eye reacts to light, and to use such information for biometric recognition purposes. The results demonstrate that these features are discriminating features, and, even using the Euclidean distance measure, an average accuracy of recognition of 99.1% was obtained. The proposed methodology has the potential to be "fraud-proof," because these DFs can only be extracted from living irises.

  4. Longitudinal study of fingerprint recognition.

    Human identification by fingerprints is based on the fundamental premise that ridge patterns from distinct fingers are different (uniqueness) and a fingerprint pattern does not change over time (persistence). Although the uniqueness of fingerprints has been investigated by developing statistical models to estimate the probability of error in comparing two random samples of fingerprints, the persistence of fingerprints has remained a general belief based on only a few case studies. In this study, fingerprint match (similarity) scores are analyzed by multilevel statistical models with covariates such as time interval between two fingerprints in comparison, subject's age, and fingerprint image quality. Longitudinal fingerprint records of 15,597 subjects are sampled from an operational fingerprint database such that each individual has at least five 10-print records over a minimum time span of 5 y. In regard to the persistence of fingerprints, the longitudinal analysis on a single (right index) finger demonstrates that (i) genuine match scores tend to significantly decrease when time interval between two fingerprints in comparison increases, whereas the change in impostor match scores is negligible; and (ii) fingerprint recognition accuracy at operational settings, nevertheless, tends to be stable as the time interval increases up to 12 y, the maximum time span in the dataset. However, the uncertainty of temporal stability of fingerprint recognition accuracy becomes substantially large if either of the two fingerprints being compared is of poor quality. The conclusions drawn from 10-finger fusion analysis coincide with the conclusions from single-finger analysis.

    Full Text Available In a system of speech recognition containing words, the recognition requires the comparison between the entry signal of the word and the various words of the dictionary. The problem can be solved efficiently by a dynamic comparison algorithm whose goal is to put in optimal correspondence the temporal scales of the two words. An algorithm of this type is Dynamic Time Warping. This paper presents two alternatives for implementation of the algorithm designed for recognition of the isolated words.

    A novel syntactic approach is introduced to treat particular problems in pattern recognition. The procedure is implemented by the use of optical correlation methods for identifying the various primitives that appear in the input pattern, and their importance is determined by fuzzy relational scoring. Robust pattern recognition with tolerance to normal variations is demonstrated, indicating an efficient new approach for optical pattern recognition. {copyright} {ital 1996 Optical Society of America.}

    2013-01-01

    Chiral recognition phenomena play an important role in nature as well as analytical separation sciences. In separation sciences such as chromatography and capillary electrophoresis, enantiospecific interactions between the enantiomers of an analyte and the chiral selector are required in order to observe enantioseparations. Due to the large structural variety of chiral selectors applied, different mechanisms and structural features contribute to the chiral recognition process. This chapter briefly illustrates the current models of the enantiospecific recognition on the structural basics of various chiral selectors.

    Facial emotion recognition impairments have been reported in Huntington's disease (HD). However, the nature of the impairments across the spectrum of HD remains unclear. We report on emotion recognition data from 344 participants comprising premanifest HD (PreHD) and early HD patients, and controls. In a test of recognition of facial emotions, we examined responses to six basic emotional expressions and neutral expressions. In addition, and within the early HD sample, we tested for differences on emotion recognition performance between those 'on' vs. 'off' neuroleptic or selective serotonin reuptake inhibitor (SSRI) medications. The PreHD groups showed significant (pfaces; whereas the early HD groups were significantly impaired across all emotions including neutral expressions. In early HD, neuroleptic use was associated with worse facial emotion recognition, whereas SSRI use was associated with better facial emotion recognition. The findings suggest that emotion recognition impairments exist across the HD spectrum, but are relatively more widespread in manifest HD than in the premanifest period. Commonly prescribed medications to treat HD-related symptoms also appear to affect emotion recognition. These findings have important implications for interpersonal communication and medication usage in HD. Copyright © 2012 Elsevier Ireland Ltd. All rights reserved.

  17. Unthinkability and psychosomatic symptoms.

    Science.gov (United States)

    Neri, C

    W. R. Bion (1952) has pointed out a connection between alterations in the development of the "apparatus for thinking thoughts" and psychosomatic symptoms. Many authors have used this insight, from their own points of view, as a basis for describing this deficiency in thought and in the capacity to formulate images related to the development of psychosomatic symptoms (Krystal & McDougall 1979; Segal, 1950, 1958). This paper applies this hypothesis to a clinical case in which special emphasis is given to the symbolic deficiency, its effect on transference-countertransference, and its relation to falsification, "hyposymbolization," and to a specific phenomenon that could be called "hypersymbolization," in which many meanings are embodied in the same symbol.

  20. Respiratory symptoms of megaesophagus

    Directory of Open Access Journals (Sweden)

    Fabio Di Stefano

    2013-03-01

    Full Text Available Megaesophagus as the end result of achalasia is the consequence of disordered peristalsis and the slow decompensation of the esophageal muscular layer. The main symptoms of achalasia are dysphagia, regurgitation, chest pain and weight loss, but respiratory symptoms, such as coughing, particularly when patients lie in a horizontal position, may also be common due to microaspiration. A 70-year old woman suffered from a nocturnal cough and shortness of breath with stridor. She reported difficulty in swallowing food over the past ten years, but had adapted by eating a semi-liquid diet. Chest X-ray showed right hemithorax patchy opacities projecting from the posterior mediastinum. Chest computed tomography scan showed a marked dilatation of the esophagus with abundant food residues. Endoscopy confirmed the diagnosis of megaesophagus due to esophageal achalasia, excluding other causes of obstruction, such as secondary esophagitis, polyps, leiomyoma or leiomyosarcoma. In the elderly population, swallowing difficulties due to esophageal achalasia are often underestimated and less troublesome than the respiratory symptoms that are caused by microaspiration. The diagnosis of esophageal achalasia, although uncommon, should be considered in patients with nocturnal chronic coughs and shortness of breath with stridor when concomitant swallowing difficulties are present.

  1. Neurobiology Underlying Fibromyalgia Symptoms

    Directory of Open Access Journals (Sweden)

    Marta Ceko

    2012-01-01

    Full Text Available Fibromyalgia is characterized by chronic widespread pain, clinical symptoms that include cognitive and sleep disturbances, and other abnormalities such as increased sensitivity to painful stimuli, increased sensitivity to multiple sensory modalities, and altered pain modulatory mechanisms. Here we relate experimental findings of fibromyalgia symptoms to anatomical and functional brain changes. Neuroimaging studies show augmented sensory processing in pain-related areas, which, together with gray matter decreases and neurochemical abnormalities in areas related to pain modulation, supports the psychophysical evidence of altered pain perception and inhibition. Gray matter decreases in areas related to emotional decision making and working memory suggest that cognitive disturbances could be related to brain alterations. Altered levels of neurotransmitters involved in sleep regulation link disordered sleep to neurochemical abnormalities. Thus, current evidence supports the view that at least some fibromyalgia symptoms are associated with brain dysfunctions or alterations, giving the long-held “it is all in your head” view of the disorder a new meaning.

    Bladder pain syndrome/interstitial cystitis is a poorly understood condition that can cause serious disability. We provide the first population based symptom prevalence estimate to our knowledge among United States adult females. We developed and validated 2 case definitions to identify bladder pain syndrome/interstitial cystitis symptoms. Beginning in August 2007 we telephoned United States households, seeking adult women with bladder symptoms or a bladder pain syndrome/interstitial cystitis diagnosis. Second stage screening identified those subjects who met case definition criteria. Each completed a 60-minute interview on the severity and impact of bladder symptoms, health care seeking and demographics. Data collection ended in April 2009. Using population and nonresponse weights we calculated prevalence estimates based on definitions spanning a range of sensitivity and specificity. We used United States Census counts to estimate the number of affected women in 2006. The random sample included 146,231 households, of which 131,691 included an adult female. Of these households 32,474 reported an adult female with bladder symptoms or diagnosis, of which 12,752 completed the questionnaire. Based on the high sensitivity definition 6.53% (95% CI 6.28, 6.79) of women met symptom criteria. Based on the high specificity definition 2.70% (95% CI 2.53, 2.86) of women met the criteria. These percentages translated into 3.3 to 7.9 million United States women 18 years old or older with bladder pain syndrome/interstitial cystitis symptoms. Symptom severity and impact were comparable to those of adult women with established diagnoses. However, only 9.7% of the women reported being assigned a bladder pain syndrome/interstitial cystitis diagnosis. Bladder pain syndrome/interstitial cystitis symptoms are widespread among United States women and associated with considerable disability. These results suggest bladder pain syndrome/interstitial cystitis may be underdiagnosed. Copyright

    Echolocating bats have excellent spatial memory and are able to navigate to salient locations using bio-sonar. Navigating and route-following require animals to recognize places. Currently, it is mostly unknown how bats recognize places using echolocation. In this paper, we propose template based place recognition might underlie sonar-based navigation in bats. Under this hypothesis, bats recognize places by remembering their echo signature - rather than their 3D layout. Using a large body of ensonification data collected in three different habitats, we test the viability of this hypothesis assessing two critical properties of the proposed echo signatures: (1) they can be uniquely classified and (2) they vary continuously across space. Based on the results presented, we conclude that the proposed echo signatures satisfy both criteria. We discuss how these two properties of the echo signatures can support navigation and building a cognitive map.

    1997-01-01

    Law enforcement agencies need to identify suspects as they travel around the world. Terrorists and others change all sorts of information about themselves but their faces remain the same. The first operational facial recognition system (face trace) was developed at the Central Intelligence Agency (CIA) in the late eighties. It combines image analysis technology with collateral information to create an 'electronic mug book.' Using some simple collateral information about a suspect (height, age and sex) and a photograph, the system gives users the ability to identify an unknown person with a reasonable probability. The system matches information extracted from the photographs with similar information extracted from a database of photographs of existing suspects. The technology was subsequently transferred to the Immigration and Naturalization Service (INS) for use by the Border Patrol.

  13. Differences in Facial Emotion Recognition between First Episode Psychosis, Borderline Personality Disorder and Healthy Controls.

    Directory of Open Access Journals (Sweden)

    Ana Catalan

    Full Text Available Facial emotion recognition (FER is essential to guide social functioning and behaviour for interpersonal communication. FER may be altered in severe mental illness such as in psychosis and in borderline personality disorder patients. However, it is unclear if these FER alterations are specifically related to psychosis. Awareness of FER alterations may be useful in clinical settings to improve treatment strategies. The aim of our study was to examine FER in patients with severe mental disorder and their relation with psychotic symptomatology.Socio-demographic and clinical variables were collected. Alterations on emotion recognition were assessed in 3 groups: patients with first episode psychosis (FEP (n = 64, borderline personality patients (BPD (n = 37 and healthy controls (n = 137, using the Degraded Facial Affect Recognition Task. The Positive and Negative Syndrome Scale, Structured Interview for Schizotypy Revised and Community Assessment of Psychic Experiences scales were used to assess positive psychotic symptoms. WAIS III subtests were used to assess IQ.Kruskal-Wallis analysis showed a significant difference between groups on the FER of neutral faces score between FEP, BPD patients and controls and between FEP patients and controls in angry face recognition. No significant differences were found between groups in the fear or happy conditions. There was a significant difference between groups in the attribution of negative emotion to happy faces. BPD and FEP groups had a much higher tendency to recognize happy faces as negatives. There was no association with the different symptom domains in either group.FEP and BPD patients have problems in recognizing neutral faces more frequently than controls. Moreover, patients tend to over-report negative emotions in recognition of happy faces. Although no relation between psychotic symptoms and FER alterations was found, these deficits could contribute to a patient's misinterpretations in daily life.

    Biometrics refers to unique human characteristics. Each unique characteristic may be used to label and describe individuals and for automatic recognition of a person based on physiological or behavioural properties. One of the most natural and the most popular biometric trait is a face. The most common research methods on face recognition are based on visible light. State-of-the-art face recognition systems operating in the visible light spectrum achieve very high level of recognition accuracy under controlled environmental conditions. Thermal infrared imagery seems to be a promising alternative or complement to visible range imaging due to its relatively high resistance to illumination changes. A thermal infrared image of the human face presents its unique heat-signature and can be used for recognition. The characteristics of thermal images maintain advantages over visible light images, and can be used to improve algorithms of human face recognition in several aspects. Mid-wavelength or far-wavelength infrared also referred to as thermal infrared seems to be promising alternatives. We present the study on 1:1 recognition in thermal infrared domain. The two approaches we are considering are stand-off face verification of non-moving person as well as stop-less face verification on-the-move. The paper presents methodology of our studies and challenges for face recognition systems in the thermal infrared domain.

  3. Physiological arousal in processing recognition information

    Directory of Open Access Journals (Sweden)

    Guy Hochman

    2010-07-01

    Full Text Available The recognition heuristic (RH; Goldstein and Gigerenzer, 2002 suggests that, when applicable, probabilistic inferences are based on a noncompensatory examination of whether an object is recognized or not. The overall findings on the processes that underlie this fast and frugal heuristic are somewhat mixed, and many studies have expressed the need for considering a more compensatory integration of recognition information. Regardless of the mechanism involved, it is clear that recognition has a strong influence on choices, and this finding might be explained by the fact that recognition cues arouse affect and thus receive more attention than cognitive cues. To test this assumption, we investigated whether recognition results in a direct affective signal by measuring physiological arousal (i.e., peripheral arterial tone in the established city-size task. We found that recognition of cities does not directly result in increased physiological arousal. Moreover, the results show that physiological arousal increased with increasing inconsistency between recognition information and additional cue information. These findings support predictions derived by a compensatory Parallel Constraint Satisfaction model rather than predictions of noncompensatory models. Additional results concerning confidence ratings, response times, and choice proportions further demonstrated that recognition information and other cognitive cues are integrated in a compensatory manner.

    Right or bilateral anterior temporal damage can impair face recognition, but whether this is an associative variant of prosopagnosia or part of a multimodal disorder of person recognition is an unsettled question, with implications for cognitive and neuroanatomic models of person recognition. We assessed voice perception and short-term recognition of recently heard voices in 10 subjects with impaired face recognition acquired after cerebral lesions. All 4 subjects with apperceptive prosopagnosia due to lesions limited to fusiform cortex had intact voice discrimination and recognition. One subject with bilateral fusiform and anterior temporal lesions had a combined apperceptive prosopagnosia and apperceptive phonagnosia, the first such described case. Deficits indicating a multimodal syndrome of person recognition were found only in 2 subjects with bilateral anterior temporal lesions. All 3 subjects with right anterior temporal lesions had normal voice perception and recognition, 2 of whom performed normally on perceptual discrimination of faces. This confirms that such lesions can cause a modality-specific associative prosopagnosia. PMID:25349193

    2008-09-01

    Interpreting facial emotion is a requisite skill that enables us to navigate our social environment. Autism spectrum disorder is characterized by shortcomings in socio-cognitive abilities in general, and in emotion recognition in particular, and much has been written on this subject. Less research, however, has been conducted on individuals with intellectual disabilities. This review discusses recent emotion recognition research in this population. Facial emotion recognition research in individuals with intellectual disabilities can be divided into two broad categories: studies on the causes of emotion recognition deficits (i.e. primary deficits or secondary phenomena) and studies on the effects of emotion recognition deficits (behavioral implications). Recent research on causes has not yet produced definitive conclusions and current research on specific effects has been limited to aggression and self-reported anger. Some evidence exists that individuals with intellectual disability of heterogeneous etiology (excluding autism) have facial affect recognition deficits that cannot be fully accounted for by cognitive-intellectual abilities. In addition, cognitive processing strategies and genetic syndrome-specific differences in facial affect recognition have been discovered but further research is needed. We found no evidence that emotion recognition deficits contribute to the emergence of later antisocial behavior.

    2012-01-01

    Over the past few decades, face recognition has become a rapidly growing research topic due to the increasing demands in many applications of our daily life such as airport surveillance, personal identification in law enforcement, surveillance systems, information safety, securing financial transactions, and computer security. The objective of this thesis is to develop a face recognition system capable of recognizing persons with a high recognition capability, low processing time, and under different illumination conditions, and different facial expressions. The thesis presents a study for the performance of the face recognition system using two techniques; the Principal Component Analysis (PCA), and the Zernike Moments (ZM). The performance of the recognition system is evaluated according to several aspects including the recognition rate, and the processing time. Face recognition systems that use visual images are sensitive to variations in the lighting conditions and facial expressions. The performance of these systems may be degraded under poor illumination conditions or for subjects of various skin colors. Several solutions have been proposed to overcome these limitations. One of these solutions is to work in the Infrared (IR) spectrum. IR images have been suggested as an alternative source of information for detection and recognition of faces, when there is little or no control over lighting conditions. This arises from the fact that these images are formed due to thermal emissions from skin, which is an intrinsic property because these emissions depend on the distribution of blood vessels under the skin. On the other hand IR face recognition systems still have limitations with temperature variations and recognition of persons wearing eye glasses. In this thesis we will fuse IR images with visible images to enhance the performance of face recognition systems. Images are fused using the wavelet transform. Simulation results show that the fusion of visible and

    2017-08-01

    Human activity recognition is one of the most important research topics in the era of Internet of Things. To separate different activities given sensory data, we utilize a Minimal Distinguishing Subsequence (MDS) mining approach to efficiently find distinguishing patterns among different activities. We first transform the sensory data into a series of sensor triggering events and operate the MDS mining procedure afterwards. The gap constraints are also considered in the MDS mining. Given the multi-class nature of most activity recognition tasks, we modify the MDS mining approach from a binary case to a multi-class one to fit the need for multiple activity recognition. We also study how to select the best parameter set including the minimal and the maximal support thresholds in finding the MDSs for effective activity recognition. Overall, the prediction accuracy is 86.59% on the van Kasteren dataset which consists of four different activities for recognition.

    2018-02-01

    Full Text Available Most motion recognition research has required tight-fitting suits for precise sensing. However, tight-suit systems have difficulty adapting to real applications, because people normally wear loose clothes. In this paper, we propose a gait recognition system with flexible piezoelectric sensors in loose clothing. The gait recognition system does not directly sense lower-body angles. It does, however, detect the transition between standing and walking. Specifically, we use the signals from the flexible sensors attached to the knee and hip parts on loose pants. We detect the periodic motion component using the discrete time Fourier series from the signal during walking. We adapt the gait detection method to a real-time patient motion and posture monitoring system. In the monitoring system, the gait recognition operates well. Finally, we test the gait recognition system with 10 subjects, for which the proposed system successfully detects walking with a success rate over 93 %.

The letters are divided into 9 groups based on the form and structure of their main bodies. After feature extraction, grouping is performed using a decision tree. Final recognition of letters is carried out in each group by delayed strokes. The proposed method is a rapid method in character recognition because time-consuming methods have not been used. Our proposed method was tested on TMU-OFS dataset, and a recognition rate of 94% and 92% was achieved for character grouping and recognition, respectively. The mean processing time for recognizing a letter was 3ms.

    The problems of digitalization and transformation of musical scores into machine-readable format are necessary to be solved since they help people to enjoy music, to learn music, to conserve music sheets, and even to assist music composers. However, the results of existing methods still require improvements for higher accuracy. Therefore, the authors propose lightweight algorithms for Optical Music Recognition to help people to recognize and automatically play musical scores. In our proposal, after removing staff lines and extracting symbols, each music symbol is represented as a grid of identical M ∗ N cells, and the features are extracted and classified with multiple lightweight SVM classifiers. Through experiments, the authors find that the size of 10 ∗ 12 cells yields the highest precision value. Experimental results on the dataset consisting of 4929 music symbols taken from 18 modern music sheets in the Synthetic Score Database show that our proposed method is able to classify printed musical scores with accuracy up to 99.56%.

    Health anxiety (HA) is an overlooked area in paediatric research. Little is known about the occurrence of HA symptoms in a child and adolescent psychiatric setting, and there are no age-appropriate diagnostic criteria and only limited number of assessment tools. It is therefore likely that HA is seen as part of obsessive-compulsive disorder (OCD) due to construct overlap and the diagnostic uncertainty of HA in this age group. In the present study, the extent of HA symptoms was investigated in 94 children and adolescents with a primary ICD-10 diagnosis of OCD. Self-reported HA symptoms were assessed using the Childhood Illness Attitude Scales. Clinician-rated OCD symptoms and severity were measured using the Children's Yale Brown Obsessive Compulsive Scale. Information on socio-demographics was obtained from the child's/adolescent's medical record. The distribution of HA symptoms resembled a normal curve shifted to the right compared with a normal population of Danish children, and 30 % presented with high HA symptoms. Chi-squared tests were used to examine the proportion of children and adolescents with high HA symptoms in relation to various clinical characteristics. Clinician-rated illness worries and comorbid anxiety disorder were associated with high self-reported HA symptoms. The results contribute to the understanding of how HA and OCD overlap conceptually in young patients and bring attention to the need for improved recognition of OCD patients dominated by illness worries. Further research in the description of childhood HA is important in order to understand whether HA is a distinct disorder early in life.

    This study aimed to evaluate the ability to decode emotion in the auditory and audiovisual modality in a group of patients with schizophrenia, and to explore the role of cognition and psychopathology in affecting these emotion recognition abilities. Ninety-four outpatients in a stable phase and 51 healthy subjects were recruited. Patients were assessed through a psychiatric evaluation and a wide neuropsychological battery. All subjects completed the comprehensive affect testing system (CATS), a group of computerized tests designed to evaluate emotion perception abilities. With respect to the controls, patients were not impaired in the CATS tasks involving discrimination of nonemotional prosody, naming of emotional stimuli expressed by voice and judging the emotional content of a sentence, whereas they showed a specific impairment in decoding emotion in a conflicting auditory condition and in the multichannel modality. Prosody impairment was affected by executive functions, attention and negative symptoms, while deficit in multisensory emotion recognition was affected by executive functions and negative symptoms. These emotion recognition deficits, rather than being associated purely with emotion perception disturbances in schizophrenia, are affected by core symptoms of the illness.

    2017-04-01

    Full Text Available Physical symptoms without any identifiable structural or biochemical abnormalities on detailed clinical examination and investigations, are common in children. Some children may have persistent physical discomfort which can lead to debilitating impact on their academic and social functioning. These children seek repeated medical consultations and are usually subjected to unnecessary invasive diagnostic procedures. It is extremely important to understand that emotional factors can contribute to the development as well as maintenance of impairing physical symptoms. There is scientific evidence for the association of anxiety and functional somatic symptoms in children. The diagnostic category which was previously called somatoform disorders is now included in somatic symptom disorders. The main feature of the somatic symptom disorders is the excessive concern with somatic symptoms. Detailed clinical examination and investigations will not reveal any abnormalities to explain the symptoms. The somatic symptom disorders are common in childhood. Cognitive behavioural therapy by experts in child guidance, will relieve the somatic symptoms related to anxiety and stress. If not intervened at the earliest, the persistent physical symptoms associated with emotional stress will cause significant functional disability in childhood. Unnecessary invasive medical interventions cause more agony to the child. These children also have high risk for developing anxiety disorders and depressive disorders in young adulthood. Hence, early intervention using cognitive behavioural techniques should be provided to all children with somatic symptom disorders, which will definitely improve their quality of life.

    In spite of the fact that the good mental health is indispensable condition of the development of sound personality, in the past years the somatic and mental state of our children did not improve. The author ascertains that there are several obstacles in the recognition, treatment and prevention of child-depression that causes a serious public health problem. He stresses the neurologic, neuropsychiatric, psychopathological and diagnostic deficiencies, and the low number of Child and Youth Dispensaries. He describes the situation of Hungarian Child and Youth Dispensaries network, and states positively that today the child-psychiatric services are not able to provide optimal provision for every depressive child. In the brief historical introduction he refers the earlier excellent child-psychiatric initiative. He emphasises the huge number of somatic and psychiatric signs and symptoms among the children. He devotes a separate chapter to the causes of child-depression, the prevention, recognition, creation of diagnosis and treatment. According to the literature data and own examination he demonstrates that the depressive and other psychopathological symptoms among children are not really interested the parents, health-workers and teachers. There are several depressive symptoms among the children without mental disorders. The new revisions of BNO and DSM are unable to help the diagnostic of child-depression. He summarizes the most important tasks for the prevention and treatment of child-depression. In the near future a great deal more should be done for prevention and treatment of child-depression than what we have accomplished so far in order to ensure every child the development of sound personality and becoming healthy adult. The deep, ramified, complicated roots of self-destructive behaviour are originated from the early mental abnormalities, primarily from the Conduct, Depressive and Anxiety Disorders. The prevention and treatment of child-depression are

    Public health threats from intentional releases of chemicals into the environment (ie, chemical terrorism) are an increasing concern in the United States. Recent situations of deliberate contamination of food and beverages with chemicals highlight the need for health care providers and public health officials to be alert for adult and pediatric patients in their communities who have signs and symptoms consistent with chemical exposures. In an effort to increase knowledge of surveillance and preparedness for illness related to potential chemical releases, we provide guidance to health care providers and public health personnel for recognizing illnesses or patterns of illnesses that might be associated with the intentional, covert release of chemical agents. In this article, we will discuss 5 examples of outbreaks of illnesses after a covert chemical release, obstacles to recognition of these illnesses, clues (ie, epidemiological patterns and syndromic presentations) that might enhance the recognition of illnesses from a covert chemical release, and public health strategies to enhance the rapid identification of a chemical terrorism event.

    Mental Health Literacy (MHL), namely recognition, and beliefs about treatment concerning Anorexia Nervosa (AN) were examined in a community sample of male and female (n = 983) aged 15-94 years. A vignette describing a women suffering from the symptoms of AN was presented, followed by a respondent-based structured interview concerning recognition of the problem and treatment beliefs. The majority of participants could identify the problem as that of an eating disorder, although only 16.1% could specifically identify it as AN. Many also believed the problem was primarily one of low self-esteem (32.5%). General practitioners and psychiatrists or psychologists were considered the most helpful treatment providers, while obtaining information about the problem and available services, followed by family therapy, were considered the most helpful treatments. Less than one-third of participants believed complete recovery was possible. Better AN MHL was found in younger, higher educated, and metropolitan domiciled females. This study offers encouraging results in regard to AN MHL. In particular, there was moderate regard for the use of mental health specialists in the treatment of the disorder. However, there appears to be a misconception that AN is largely the manifestation of low self-esteem and confusion concerning the distinction between AN and bulimia nervosa. AN MHL was poorer in males and those with higher social and health disadvantage. Copyright © 2010 Wiley Periodicals, Inc.

    The growing interest in affective computing (AC) brings a lot of valuable research topics that can meet different application demands in enterprise systems. The present study explores a sub area of AC techniques - textual emotion recognition for enhancing enterprise computing. Multi-label emotion recognition in text is able to provide a more comprehensive understanding of emotions than single label emotion recognition. A representation of 'emotion state in text' is proposed to encompass the multidimensional emotions in text. It ensures the description in a formal way of the configurations of basic emotions as well as of the relations between them. Our method allows recognition of the emotions for the words bear indirect emotions, emotion ambiguity and multiple emotions. We further investigate the effect of word order for emotional expression by comparing the performances of bag-of-words model and sequence model for multi-label sentence emotion recognition. The experiments show that the classification results under sequence model are better than under bag-of-words model. And homogeneous Markov model showed promising results of multi-label sentence emotion recognition. This emotion recognition system is able to provide a convenient way to acquire valuable emotion information and to improve enterprise competitive ability in many aspects.

  12. Automatic Door Access System Using Face Recognition

    Full Text Available Abstract Most doors are controlled by persons with the use of keys security cards password or pattern to open the door. Theaim of this paper is to help users forimprovement of the door security of sensitive locations by using face detection and recognition. Face is a complex multidimensional structure and needs good computing techniques for detection and recognition. This paper is comprised mainly of three subsystems namely face detection face recognition and automatic door access control. Face detection is the process of detecting the region of face in an image. The face is detected by using the viola jones method and face recognition is implemented by using the Principal Component Analysis PCA. Face Recognition based on PCA is generally referred to as the use of Eigenfaces.If a face is recognized it is known else it is unknown. The door will open automatically for the known person due to the command of the microcontroller. On the other hand alarm will ring for the unknown person. Since PCA reduces the dimensions of face images without losing important features facial images for many persons can be stored in the database. Although many training images are used computational efficiency cannot be decreased significantly. Therefore face recognition using PCA can be more useful for door security system than other face recognition schemes.

  13. Window Size Impact in Human Activity Recognition

    Oresti Banos

    2014-04-01

    Full Text Available Signal segmentation is a crucial stage in the activity recognition process; however, this has been rarely and vaguely characterized so far. Windowing approaches are normally used for segmentation, but no clear consensus exists on which window size should be preferably employed. In fact, most designs normally rely on figures used in previous works, but with no strict studies that support them. Intuitively, decreasing the window size allows for a faster activity detection, as well as reduced resources and energy needs. On the contrary, large data windows are normally considered for the recognition of complex activities. In this work, we present an extensive study to fairly characterize the windowing procedure, to determine its impact within the activity recognition process and to help clarify some of the habitual assumptions made during the recognition system design. To that end, some of the most widely used activity recognition procedures are evaluated for a wide range of window sizes and activities. From the evaluation, the interval 1–2 s proves to provide the best trade-off between recognition speed and accuracy. The study, specifically intended for on-body activity recognition systems, further provides designers with a set of guidelines devised to facilitate the system definition and configuration according to the particular application requirements and target activities.

  14. Efficient Interaction Recognition through Positive Action Representation

    Directory of Open Access Journals (Sweden)

    Tao Hu

    2013-01-01

    Full Text Available This paper proposes a novel approach to decompose two-person interaction into a Positive Action and a Negative Action for more efficient behavior recognition. A Positive Action plays the decisive role in a two-person exchange. Thus, interaction recognition can be simplified to Positive Action-based recognition, focusing on an action representation of just one person. Recently, a new depth sensor has become widely available, the Microsoft Kinect camera, which provides RGB-D data with 3D spatial information for quantitative analysis. However, there are few publicly accessible test datasets using this camera, to assess two-person interaction recognition approaches. Therefore, we created a new dataset with six types of complex human interactions (i.e., named K3HI, including kicking, pointing, punching, pushing, exchanging an object, and shaking hands. Three types of features were extracted for each Positive Action: joint, plane, and velocity features. We used continuous Hidden Markov Models (HMMs to evaluate the Positive Action-based interaction recognition method and the traditional two-person interaction recognition approach with our test dataset. Experimental results showed that the proposed recognition technique is more accurate than the traditional method, shortens the sample training time, and therefore achieves comprehensive superiority.

    2007-04-01

    This paper presents a novel iris coding method based on differences of discrete cosine transform (DCT) coefficients of overlapped angular patches from normalized iris images. The feature extraction capabilities of the DCT are optimized on the two largest publicly available iris image data sets, 2,156 images of 308 eyes from the CASIA database and 2,955 images of 150 eyes from the Bath database. On this data, we achieve 100 percent Correct Recognition Rate (CRR) and perfect Receiver-Operating Characteristic (ROC) Curves with no registered false accepts or rejects. Individual feature bit and patch position parameters are optimized for matching through a product-of-sum approach to Hamming distance calculation. For verification, a variable threshold is applied to the distance metric and the False Acceptance Rate (FAR) and False Rejection Rate (FRR) are recorded. A new worst-case metric is proposed for predicting practical system performance in the absence of matching failures, and the worst case theoretical Equal Error Rate (EER) is predicted to be as low as 2.59 x 10(-4) on the available data sets.

    1986-01-01

    1 - Description of program or function: PATTER is an interactive program with extensive facilities for modeling analytical processes and solving complex data analysis problems using statistical methods, spectral analysis, and pattern recognition techniques. PATTER addresses the type of problem generally stated as follows: given a set of objects and a list of measurements made on these objects, is it possible to find or predict a property of the objects which is not directly measurable but is known to define some unknown relationship? When employed intelligently, PATTER will act upon a data set in such a way it becomes apparent if useful information, beyond that already discerned, is contained in the data. 2 - Method of solution: In order to solve the general problem, PATTER contains preprocessing techniques to produce new variables that are related to the values of the measurements which may reduce the number of variables and/or reveal useful information about the 'obscure' property; display techniques to represent the variable space in some way that can be easily projected onto a two- or three-dimensional plot for human observation to see if any significant clustering of points occurs; and learning techniques based on both unsupervised and supervised methods, to extract as much information from the data as possible so that the optimum solution can be found

    The authors examined the prevalence of respiratory symptoms and determined whether respiratory symptoms were associated with prevalence of chest pain and number of acute painful episodes in children and adolescents with sickle cell disease. Participants (N = 93; 44 females, 49 males; mean age 9.8 +/- 4.3 years) reported coughing in the morning (21.5%), at night (31.2%), and during exercise (30.1%). Wheezing occurred both when they had a cold or infection (29.0%) and when they did not have (23.7%) a cold or infection. Sleep was disturbed by wheezing in 20.4%. Among the 76 patients who were school-age (>5 years), 19.7% of patients missed more than 4 days of school because of respiratory symptoms. The majority of patients reported having acute painful episodes (82.8%), and most (66.7%) reported having chest pain during acute painful episodes in the previous 12 months. Participants with acute pain episodes greater than 3 during the previous 12 months had significantly higher reports of breathing difficulties (P = .01) and chest pain (P = .002). The high number of respiratory symptoms (cough and wheeze) among patients with sickle cell disease may trigger acute painful episodes. Early screening and recognition, ongoing monitoring, and proactive management of respiratory symptoms may minimize the number of acute painful episodes.

    2011-10-26

    Most people with Parkinson's disease (PD) have some non-motor symptoms such as sleep disturbance. Some will have impulse control disorders manifested as pathological gambling, hypersexuality, binge eating or compulsive shopping. Others show lack of initiative, indifference and lack of emotional response. This apathy, which is distinct from depression, has been reported to be present in 70 per cent of people with PD. This study examined 99 non-demented people with PD and found that quality of life was reduced in those with either of these impulse control disorders. The behavioural changes put a strain on relationships, and apathy resulted in a withdrawal from relationships and hobbies. The authors emphasise the need to diagnose and manage complications in a timely manner.

    Computer model-building procedures using stereochemical principles together with theoretical energy calculations appear to be, at this stage, the most promising route toward the elucidation of DNA-protein binding schemes and recognition principles. A review of models and bonding principles is conducted and approaches to modeling are considered, taking into account possible di-hydrogen-bonding schemes between a peptide and a base (or a base pair) of a double-stranded nucleic acid in the major groove, aspects of computer graphic modeling, and a search for isogeometric helices. The energetics of recognition complexes is discussed and several models for peptide DNA recognition are presented.

    This paper briefly reviews recent developments regarding the brain mechanisms of visual self-recognition. A special cognitive mechanism for visual self-recognition has been postulated based on behavioral and neuropsychological evidence, but its neural substrate remains controversial. Recent functional imaging studies suggest that multiple cortical mechanisms play self-specific roles during visual self-recognition, reconciling the existing controversy. Respective roles for the left occipitotemporal, right parietal, and frontal cortices in symbolic, visuospatial, and conceptual aspects of self-representation have been proposed. (author)

    This report describes a combination of statistical and syntactical pattern recongition methods. The hierarchically structured recognition system consists of a conventional statistical classifier, a structural classifier analysing the topological composition of the patterns, a stage reducing the number of hypotheses made by the first two stages, and a mixed stage based on a search for maximum similarity between syntactically generated prototypes and patterns. The stages work on different principles to avoid mistakes made in one stage in the other stages. This concept is applied to the recognition of numerals written without constraints. If no samples are rejected, a recognition rate of 99,5% is obtained. (orig.) [de

    We propose an alternative way to study the problem of visual recognition which is closer to the spirit emerging from Brooks' work on building robots than to Marr's reconstructive approach. Our theory is purposive in the sense that recognition is considered in the context of an agent performing it in an environment, along with the agent's intentions that translate into a set of behaviors; it is qualitative in the sense that only partial recovery is needed; it is active in the sense that various partial recovery tasks need for recognition are achieved through active vision; and it is opportunistic in the sense that every available cue is used.

    2011-01-01

    Advanced presentation of breast cancer and the problem of late diagnosis is well documented. Patient delay beyond three months has been shown to reduce survival. This paper aims to explore the experience of Malaysian women presenting with advanced breast cancer with regards to their interpretation of breast symptoms. Purposive sampling of 19 breast cancer patients presenting with delayed treatment and/ or advanced cancer diagnosed within two years at the University Malaya Medical Centre, Kuala Lumpur were carried out. In-depth interviews were conducted using a self-devised interview guide. The interview guide covered the journey of the patient from discovering of symptoms to their present state. The audiotaped interviews were transcribed verbatim. NVivo 8 qualitative software was utilised for data management. Grounded theory with thematic analysis was utilised. Nine women delayed seeking diagnosis although recognizing the symptom, five did not recognize symptom, three delayed treatment and two did not delay health attention. Themes that emerged with regards to triggering help seeking behavior were: a) poor symptom knowledge and recognition; b) importance of knowledge of the disease and its' outcomes; c) role of coping mechanisms and affect; and lastly d) role of significant others in appraising a breast symptom. Symptom recognition remains an important public health issue in Malaysia. Educating women, their significant others and primary health and primary care providers in detecting early staged breast cancer are needed. Supporting and sanctioning women with breast symptoms are important. The psycho-social-cultural model of symptom appraisal may serve as an important addition to the fight against cancer in countries that do not have the resources for population based screening mammogram programmes.

    To investigate the reliability, validity and utility of DSM-5 illness anxiety disorder (IAD) and somatic symptom disorder (SSD), and explore their overlap with DSM-IV Hypochondriasis in a health anxious sample. Treatment-seeking patients with health anxiety (N=118) completed structured diagnostic interviews to assess DSM-IV Hypochondriasis, DSM-5 IAD, SSD, and comorbid mental disorders, and completed self-report measures of health anxiety, comorbid symptoms, cognitions and behaviours, and service utilization. IAD and SSD were more reliable diagnoses than Hypochondriasis (kappa estimates: IAD: 0.80, SSD: 0.92, Hypochondriasis: 0.60). 45% of patients were diagnosed with SSD, 47% with IAD, and 8% with comorbid IAD/SSD. Most patients with IAD fluctuated between seeking and avoiding care (61%), whereas care-seeking (25%) and care-avoidant subtypes were less common (14%). Half the sample met criteria for DSM-IV Hypochondriasis; of those, 56% met criteria for SSD criteria, 36% for IAD, and 8% for comorbid IAD/SSD. Compared to IAD, SSD was characterized by more severe health anxiety, somatic symptoms, depression, and higher health service use, and higher rates of major depressive disorder, panic disorder and agoraphobia. DSM-5 IAD and SSD classifications reliably detect more cases of clinically significant health anxiety than DSM-IV Hypochondriasis. The differences between IAD and SSD appear to be due to severity. Future research should explore the generalizability of these findings to other samples, and whether diagnostic status predicts treatment response and long-term outcome. Copyright © 2017 Elsevier Inc.

    Spontaneous transmural rupture of the esophagus (Boerhaave's syndrome) is a life-threatening emergency. Prompt diagnosis is essential to a better prognosis, successful operative outcome and patient survival. The chest roentgenogram and the contrast esophagograms to follow are the most helpful diagnostic tests. The clinical manifestations are variable and may be misleading and thus delay accurate recognition. In our case report the major clinical features and radiological signs of Boerhaave's syndrome are described. The pathogenesis, characteristic clinical symptoms and the signs and radiological evaluation are reviewed. (orig.) [de

    Wild mushroom poisoning is often reported to cause acute liver or renal failure. However, acute rhabdomyolysis caused by wild mushroom poisoning has rarely been reported. We describe 7 patients of 1 family with Russula subnigricans Hongo poisoning. Their clinical manifestations varied from gastrointestinal symptoms to rhabdomyolysis, with 1 fatality. Our report provides supporting evidence that rhabdomyolysis may result from ingestion of R subnigricans mushrooms. A key to survival for patients with rhabdomyolysis caused by R subnigricans poisoning may be early recognition and intensive supportive care. Copyright © 2015 Wilderness Medical Society.

    Prompt utilization of health services on detecting breast symptoms can improve breast cancer (BC) survival. Little is known about Chinese women's help-seeking behaviour. Our aim was to determine patterns of self-referral among Hong Kong Chinese women with self-detected breast symptoms. We recruited 37 women awaiting their first consultation at public hospitals for breast symptoms. Interviews were transcribed and analysed based on the grounded theory approaches. A two-stage help-seeking model provided the best interpretation of the data. Symptom recognition was triggered by symptom interpretation, symptom progression and social messages. Painful lumps were seen as symptomatic, but atypical symptoms were often dismissed as benign as they responded to dietary change. Symptom intensification and discussions with someone who had faced BC prompted consultation. Service utilization involved fear of consequences, confirmation need, symptom distress, lay referral, media prompts and opportunistic presentation. Fearing cancer as incurable delayed consultation. Utilization barriers included cost, uncertainty about referral pathways, competing priorities and embarrassment. Atypical and painless presentation was more common among women delaying presentation. Barriers included cost, access, time and embarrassment. Education should emphasize atypical symptoms, the high-cure rate and the need for early presentation. Reduced cost and improved access to clinics would enhance early consultation.

    Novel Techniques for Dialectal Arabic Speech describes approaches to improve automatic speech recognition for dialectal Arabic. Since speech resources for dialectal Arabic speech recognition are very sparse, the authors describe how existing Modern Standard Arabic (MSA) speech data can be applied to dialectal Arabic speech recognition, while assuming that MSA is always a second language for all Arabic speakers. In this book, Egyptian Colloquial Arabic (ECA) has been chosen as a typical Arabic dialect. ECA is the first ranked Arabic dialect in terms of number of speakers, and a high quality ECA speech corpus with accurate phonetic transcription has been collected. MSA acoustic models were trained using news broadcast speech. In order to cross-lingually use MSA in dialectal Arabic speech recognition, the authors have normalized the phoneme sets for MSA and ECA. After this normalization, they have applied state-of-the-art acoustic model adaptation techniques like Maximum Likelihood Linear Regression (MLLR) and M...

    Facial expressions are a key index of emotion and the interpretation of such expressions of emotion is critical to everyday social functioning. In this paper, we present an efficient video analysis technique for recognition of a specific expression, pain, from human faces. We employ an automatic face detector which detects face from the stored video frame using skin color modeling technique. For pain recognition, location and shape features of the detected faces are computed. These features are then used as inputs to a support vector machine (SVM) for classification. We compare the results with neural network based and eigenimage based automatic pain recognition systems. The experiment results indicate that using support vector machine as classifier can certainly improve the performance of automatic pain recognition system.

    Full Text Available We present a gesture recognition method derived from particle swarm movement for free-air hand gesture recognition. Online gesture recognition remains a difficult problem due to uncertainty in vision-based gesture boundary detection methods. We suggest an automated process of segmenting meaningful gesture trajectories based on particle swarm movement. A subgesture detection and reasoning method is incorporated in the proposed recognizer to avoid premature gesture spotting. Evaluation of the proposed method shows promising recognition results: 97.6% on preisolated gestures, 94.9% on stream gestures with assistive boundary indicators, and 94.2% for blind gesture spotting on digit gesture vocabulary. The proposed recognizer requires fewer computation resources; thus it is a good candidate for real-time applications.

    behaviour is thought to be rare in one of the classic examples of cooperation--social insect colonies--because the colony-level costs of individual selfishness select against cues that would allow workers to recognize their closest relatives. In accord with this, previous studies of wasps and ants have...... found little or no kin information in recognition cues. Here, we test the hypothesis that social insects do not have kin-informative recognition cues by investigating the recognition cues and relatedness of workers from four colonies of the ant Acromyrmex octospinosus. Contrary to the theoretical...... prediction, we show that the cuticular hydrocarbons of ant workers in all four colonies are informative enough to allow full-sisters to be distinguished from half-sisters with a high accuracy. These results contradict the hypothesis of non-heritable recognition cues and suggest that there is more potential...

    As the main objects, imagoes have been researched in quarantine pest recognition in these days. However, pests in their larval stage are latent, and the larvae spread abroad much easily with the circulation of agricultural and forest products. It is presented in this paper that, as the new research objects, larvae are recognized by means of machine vision, image processing and pattern recognition. More visional information is reserved and the recognition rate is improved as color image segmentation is applied to images of larvae. Along with the characteristics of affine invariance, perspective invariance and brightness invariance, scale invariant feature transform (SIFT) is adopted for the feature extraction. The neural network algorithm is utilized for pattern recognition, and the automatic identification of larvae images is successfully achieved with satisfactory results.
