RESUMO

BACKGROUND: In high-resource settings, structured diabetes self-management education is associated with improved outcomes but the evidence from low-resource settings is limited and inconclusive. AIM: To compare, structured diabetes self-management education to usual care, in adults with type 2 diabetes, in low-resource settings. DESIGN: Single-blind randomised parallel comparator controlled multi-centre trial. Adults (> 18 years) with type 2 diabetes from two hospitals in urban Ghana were randomised 1:1 to usual care only, or usual care plus a structured diabetes self-management education program. Randomisation codes were computer-generated, and allotment concealed in opaque numbered envelopes. The intervention effect was assessed with linear mixed models. MAIN OUTCOME: Change in HbA1c after 3-month follow-up. Primary analysis involved all participants. CLINICALTRIAL: gov identifier:NCT04780425, retrospectively registered on 03/03/2021. RESULTS: Recruitment: 22nd until 29th January 2021. We randomised 206 participants (69% female, median age 58 years [IQR: 49-64], baseline HbA1c median 64 mmol/mol [IQR: 45-88 mmol/mol],7.9%[IQR: 6.4-10.2]). Primary outcome data was available for 79 and 80 participants in the intervention and control groups, respectively. Reasons for loss to follow-up were death (n = 1), stroke(n = 1) and unreachable or unavailable (n = 47). A reduction in HbA1c was found in both groups; -9 mmol/mol [95% CI: -13 to -5 mmol/mol], -0·9% [95% CI: -1·2% to -0·51%] in the intervention group and -3 mmol/mol [95% CI -6 to 1 mmol/mol], -0·3% [95% CI: -0·6% to 0.0%] in the control group. The intervention effect was 1 mmol/mol [95%CI:-5 TO 8 p = 0.726]; 0.1% [95% CI: -0.5, 0.7], p = 0·724], adjusted for site, age, and duration of diabetes. No significant harms were observed. CONCLUSION: In low-resource settings, diabetes self-management education might not be associated with glycaemic control. Clinician's expectations from diabetes self-management education must therefore be guarded.

RESUMO

BACKGROUND: Biobanking and genomic research requires collection and storage of human tissue from study participants. From participants' perspectives within the African context, this can be associated with fears and misgivings due to a myriad of factors including myths and mistrust of researchers. From the researchers angle ethical dilemmas may arise especially with consenting and sample reuse during storage. The aim of this paper was to explore these ethical considerations in the establishment and conduct of biobanking and genomic studies in Africa. METHODS: We conducted a narrative synthesis following a comprehensive search of nine (9) databases and grey literature. All primary research study designs were eligible for inclusion as well as both quantitative and qualitative evidence from peer reviewed journals, spanning a maximum of 20 years (2000-2020). It focused on research work conducted in Africa, even if data was stored or analysed outside the region. RESULTS: Of 2,663 title and abstracts screened, 94 full texts were retrieved and reviewed for eligibility. We included 12 studies (7 qualitative; 4 quantitative and one mixed methods). Ethical issues described in these papers related to community knowledge and understanding of biobanking and genomic research, regulation, and governance of same by research ethics committees, enrolment of participants, types of informed consents, data collection, storage, usage and sharing as well as material transfer, returning results and benefit sharing. ca. Biospecimen collection and storage is given in trust and participants expect confidentially of data and results generated. Most participants are comfortable with broad consent due to trust in researchers, though a few would like to be contacted for reconsenting in future studies, and this would depend on whether the new research is for good cause. Sharing data with external partners is welcome in some contexts but some research participants did not trust foreign researchers. CONCLUSION: Biobanking and genomic studies are a real need in Africa. Linked to this are ethical considerations related to setting up and participation in biobanks as well as data storage, export, use and sharing. There is emerging or pre-existing consensus around the acceptability of broad consent as a suitable model of consent, the need for Africans to take the lead in international collaborative studies, with deliberate efforts to build capacity in local storage and analysis of samples and employ processes of sample collection and use that build trust of communities and potential study participants. Research ethics committees, researchers and communities need to work together to work together to adapt and use clearly defined ethical frameworks, guidelines, and policy documents to harmonize the establishment and running of biobanking and genomic research in Africa.

RESUMO

AIM: To determine the association between structured diabetes self-management education (DSME) and glycaemic control in persons living with diabetes (PLD) in low- and middle-income countries (LMICs). METHODS: PubMed, Embase and Cochrane databases were searched up to June 2020 for intervention studies on the effect of structured DSME on glycaemic control in PLD in LMICs (PROSPERO registration CRD42020164857). The primary outcome was reduction in glycated haemoglobin. Included studies were assessed for risk of bias (RoB) with the Cochrane RoB tool for randomised trials. Findings were summarized in a narrative synthesis. RESULTS: Out of 154 abstracts retrieved and screened for eligibility, nine studies with a total of 1389 participants were included in the review. The structured DSME interventions were culturally tailored and were delivered in-person. They were associated with reductions in glycated haemoglobin in all studies: mean/median reduction ranged between 0.5% and 2.6% relative to baseline. CONCLUSIONS: There is a dearth of literature on the association between structured DSME and glycaemic control among PLD in LMICs. The evidence available suggests that in LMICs; particularly in sub-Saharan Africa, structured DSME is associated with reduction in glycated haemoglobin. We recommend further intervention studies on the effects of structured DSME in LMICs.

RESUMO

Objective: Compare veterinary student success at urethral catheterization of small female cats and dogs using traditional and novel 2-catheter techniques. Animal: Healthy anesthetized female cats (n = 23) and dogs (n = 6) weighing < 10 kg undergoing elective ovariohysterectomy. Procedure: Two junior (Year 3) veterinary students with no previous urethral catheterization experience participated. Each pet was catheterized by 1 student using both the traditional blind technique and the novel 2-catheter method (placement of a large red rubber catheter into the vaginal canal prior to insertion of the conventional catheter). Technique order was randomized and attempts for each technique was allowed for up to 3 min. Time to successful catheterization and catheterization success within the allotted time were recorded. Results: Successful urethral catheterization was performed using the traditional blind and novel 2-catheter techniques in 56.3 and 87.5% of cases, respectively. Conclusion: Students had a higher rate of successful catheterization with the 2-catheter catheterization technique in this report. Clinical relevance: Urethral catheterization in small female cats and dogs is technically challenging, which is compounded by the inability to consistently and reliably palpate loco-regional anatomic landmarks due to the small sized vestibules. Data from this report will be used to design future studies to assess the utility of this novel urethral catheterization technique for teaching inexperienced students this challenging clinical skill.


Résumé. Objectif: Comparez le succès des étudiants vétérinaires lors du cathétérisme urétral de petites chattes et chiennes en utilisant des techniques traditionnelles et nouvelles à deux cathéters. Animal: Chattes (n = 23) et chiennes (n = 6) en bonne santé et anesthésiées pesant < 10 kg subissant une ovariohystérectomie élective. Procédure: Deux étudiants vétérinaires juniors (3e année) sans expérience préalable en cathétérisme urétral ont participé. Chaque animal a été cathétérisé par un étudiant en utilisant à la fois la technique traditionnelle à l'aveugle et la nouvelle méthode à deux cathéters (placement d'un gros cathéter en caoutchouc rouge dans le canal vaginal avant l'insertion du cathéter conventionnel). L'ordre des techniques a été randomisé et les tentatives pour chaque technique ont été autorisées jusqu'à 3 minutes. Le temps de cathétérisme réussi et le succès du cathétérisme dans le temps accordé ont été enregistrés. Résultats: Un cathétérisme urétral réussi a été réalisé en utilisant les techniques traditionnelles à l'aveugle et les nouvelles techniques à deux cathéters dans 56,3 et 87,5 % des cas, respectivement. Conclusion: Les étudiants avaient un taux plus élevé de cathétérisme réussi avec la technique de cathétérisme à deux cathéters dans ce rapport. Pertinence clinique: Le cathétérisme urétral chez les petites chattes et chiennes est techniquement difficile, ce qui est aggravé par l'incapacité de palper de manière cohérente et fiable les repères anatomiques loco-régionaux en raison des vestibules de petite taille. Les données de ce rapport seront utilisées pour concevoir de futures études afin d'évaluer l'utilité de cette nouvelle technique de cathétérisme urétral pour enseigner aux étudiants inexpérimentés cette habileté clinique difficile.(Traduit par Dr Serge Messier).

RESUMO

This case report details a previously undescribed malignancy of the tendon sheath in a golden retriever. This dog originally presented with lameness of the left forelimb, at which point radiographs revealed a monostotic, lytic lesion of the distal radius with overlying soft-tissue swelling. A fine-needle aspirate was performed, and cytology was compatible with a sarcoma, with the primary differential being an osteosarcoma. After amputation, the leg was submitted for histopathology, which revealed inconsistencies with a typical osteosarcoma lesion, including lack of osteoid deposition. Second opinion histopathology showed a fibrosarcoma that appeared to have originated in the tendon sheath of an extensor tendon and then secondarily invaded the radius. At the time of publication, ∼17 mo after amputation, the dog continues to do well without any evidence of recurrent or metastatic disease.

RESUMO

BACKGROUND: The aim of the study was to determine the coverage of intermittent preventive treatment of malaria in pregnancy (IPTp) and its relationship with delivery outcomes among obstetric referral cases at the district level of healthcare. METHODS: An implementation research within three districts of the Greater Accra region was conducted from May 2017 to February 2018, to assess the role of an enhanced inter-facility communication system on processes and outcomes of obstetric referrals. A cross-sectional analysis of the data on IPTp coverage as well as delivery outcomes for the period of study was conducted, for all the referrals ending up in deliveries. Primary outcomes were maternal and neonatal complications at delivery. IPTp coverage was determined as percentages and classified as adequate or inadequate. Associated factors were determined using Chi square. Odds ratios (OR, 95% CI) were estimated for predictors of adequate IPTp dose coverage for associations with delivery outcomes, with statistical significance set at p = 0.05. RESULTS: From a total of 460 obstetric referrals from 16 lower level facilities who delivered at the three district hospitals, only 223 (48.5%) received adequate (at least 3) doses of IPTp. The district, type of facility where ANC is attended, insurance status, marital status and number of antenatal clinic visits significantly affected IPTp doses received. Adjusted ORs show that adequate IPTp coverage was significantly associated with new-born complication [0.80 (0.65-0.98); p = 0.03], low birth weight [0.51 (0.38-0.68); p < 0.01], preterm delivery [0.71 (0.55-0.90); p = 0.01] and malaria as indication for referral [0.70 (0.56-0.87); p < 0.01]. Positive association with maternal complication at delivery was seen but was not significant. CONCLUSION: IPTp coverage remains low in the study setting and is affected by type of health facility that ANC is received at, access to health insurance and number of times a woman attends ANC during pregnancy. This study also confirmed earlier findings that, as an intervention IPTp prevents bad outcomes of pregnancy, even among women with obstetric referrals. It is important to facilitate IPTp service delivery to pregnant women across the country, improve coverage of required doses and maximize the benefits to both mothers and newborns.

RESUMO

BACKGROUND: This study assessed health workers' adherence to neonatal health protocols before and during the implementation of a mobile health (mHealth) clinical decision-making support system (mCDMSS) that sought to bridge access to neonatal health protocol gap in a low-resource setting. METHODS: We performed a cross-sectional document review within two purposively selected clusters (one poorly-resourced and one well-resourced), from each arm of a cluster-randomized trial at two different time points: before and during the trial. The total trial consisted of 16 clusters randomized into 8 intervention and 8 control clusters to assess the impact of an mCDMSS on neonatal mortality in Ghana. We evaluated health workers' adherence (expressed as percentages) to birth asphyxia, neonatal jaundice and cord sepsis protocols by reviewing medical records of neonatal in-patients using a checklist. Differences in adherence to neonatal health protocols within and between the study arms were assessed using Wilcoxon rank-sum and permutation tests for each morbidity type. In addition, we tracked concurrent neonatal health improvement activities in the clusters during the 18-month intervention period. RESULTS: In the intervention arm, mean adherence was 35.2% (SD = 5.8%) and 43.6% (SD = 27.5%) for asphyxia; 25.0% (SD = 14.8%) and 39.3% (SD = 27.7%) for jaundice; 52.0% (SD = 11.0%) and 75.0% (SD = 21.2%) for cord sepsis protocols in the pre-intervention and intervention periods respectively. In the control arm, mean adherence was 52.9% (SD = 16.4%) and 74.5% (SD = 14.7%) for asphyxia; 45.1% (SD = 12.8%) and 64.6% (SD = 8.2%) for jaundice; 53.8% (SD = 16.0%) and 60.8% (SD = 11.7%) for cord sepsis protocols in the pre-intervention and intervention periods respectively. We observed nonsignificant improvement in protocol adherence in the intervention clusters but significant improvement in protocol adherence in the control clusters. There were 2 concurrent neonatal health improvement activities in the intervention clusters and over 12 in the control clusters during the intervention period. CONCLUSION: Whether mHealth interventions can improve adherence to neonatal health protocols in low-resource settings cannot be ascertained by this study. Neonatal health improvement activities are however likely to improve protocol adherence. Future mHealth evaluations of protocol adherence must account for other concurrent interventions in study contexts.

RESUMO

BACKGROUND: Worldwide, over half of the adolescent pregnancies recorded are unintended. The decision to continue the pregnancy to term or to opt for an abortion is a constant dilemma that is directly or indirectly influenced by stakeholders and also by the wider social environment. This study aimed at understanding the perceived decision-making preferences and determinants of early adolescent pregnancy in the Jamestown area of Accra in Ghana. METHODS: A vignette-based qualitative study design was used. Eight focus group discussions were carried among various purposively selected groups of participants: parents, teachers, adolescent students who had not been pregnant before, and adolescents who had had at least one pregnancy in the past. The vignette was a hypothetical case of a 15-year-old high school student who had not experienced her menses for the past 6 weeks. The data were analyzed using a thematic analysis approach. RESULTS: Lack of parent-daughter communication, the taboo on discussing sex-related issues in households and weak financial autonomy were considered to be the main contributing factors to the high early adolescent pregnancy rates in the community. Partner readiness to assume responsibility for the girl and the baby was a key consideration in either continuing the pregnancy to term or opting for an abortion. The father was overwhelmingly considered to be the one to take the final decision regarding the pregnancy outcome. Irrespective of the fact that the respondents were very religious, opting for an abortion was considered acceptable under special circumstances, especially if the pregnant adolescent was doing well in school. CONCLUSION: Inadequate and inappropriate communication practices around sexuality issues, as well as weak financial autonomy are the major predictors of early adolescent pregnancy in this community. The father is perceived to be the main decision maker regarding a young adolescent's pregnancy outcome. Policy-makers should carefully evaluate the implications of this overwhelming perceived desire for the father to be the final decision-maker regarding adolescent pregnancy outcomes in this community.

RESUMO

Objectives: Because medical, midwifery and law students in Ghana constitute the next generation of health care and legal practitioners, this study aimed to evaluate their attitudes towards abortion and their perceptions of the decision-making capacity of pregnant adolescents.Methods: We conducted a cross-sectional survey among 340 medical, midwifery and law students. A pretested and validated questionnaire was used to collect relevant data on respondents' sociodemographic characteristics, attitudes towards abortion and the perceived capacity and rationality of pregnant adolescents' decisions. The χ2 test of independency and Fischer's exact test were used where appropriate.Results: We retained 331 completed questionnaires for analysis. Respondents' mean age was 21.0 ± 2.9 years and the majority (95.5%) were of the Christian faith. Women made up 77.9% (n = 258) of the sample. Most students (70.1%) were strongly in favour of abortion if it was for health reasons. More than three-quarters (78.0%) of the students strongly disagreed on the use of abortion for the purposes of sex selection. Most respondents (89.0%) were not in favour of legislation to make abortion available on request for pregnant adolescents, with medical students expressing a more negative attitude compared with law and midwifery students (p < 0.001). Over half of the midwifery students (52.6%) believed that adolescents should have full decision-making capacity regarding their pregnancy outcome, compared with law and medical students (p < 0.001).Conclusion: Tensions between adolescent reproductive autonomy, the accepted culture of third party involvement (parents and partners), and the current abortion law may require keen reflection if an improvement in access to safe abortion services is envisioned.

RESUMO

OBJECTIVES: To evaluate for any association between time of admission to the PICU and mortality. DESIGN: Retrospective cohort study of admissions to PICUs in the Virtual Pediatric Systems (VPS, LLC, Los Angeles, CA) database from 2009 to 2014. SETTING: One hundred and twenty-nine PICUs in the United States. PATIENTS: Patients less than 18 years old admitted to participating PICUs; excluding those post cardiac bypass. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: A total of 391,779 admissions were included with an observed PICU mortality of 2.31%. Overall mortality was highest for patients admitted from 07:00 to 07:59 (3.32%) and lowest for patients admitted from 14:00 to 14:59 (1.99%). The highest mortality on weekdays occurred for admissions from 08:00 to 08:59 (3.30%) and on weekends for admissions from 09:00 to 09:59 (4.66%). In multivariable regression, admission during the morning 06:00-09:59 and midday 10:00-13:59 were independently associated with PICU death when compared with the afternoon time period 14:00-17:59 (morning odds ratio, 1.15; 95% CI, 1.04-1.26; p = 0.006 and midday odds ratio, 1.09; 95% CI; 1.01-1.18; p = 0.03). When separated into weekday versus weekend admissions, only morning admissions were associated with increased odds of death on weekdays (odds ratio, 1.13; 95% CI, 1.01-1.27; p = 0.03), whereas weekend admissions during the morning (odds ratio, 1.33; 95% CI, 1.14-1.55; p = 0.004), midday (odds ratio, 1.27; 95% CI, 1.11-1.45; p = 0.0006), and afternoon (odds ratio, 1.17; 95% CI, 1.03-1.32; p = 0.01) were associated with increased risk of death when compared with weekday afternoons. CONCLUSIONS: Admission to the PICU during the morning period from 06:00 to 09:59 on weekdays and admission throughout the day on weekends (06:00-17:59) were independently associated with PICU death as compared to admission during weekday afternoons. Potential contributing factors deserving further study include handoffs of care, rounds, delays related to resource availability, or unrecognized patient deterioration prior to transfer.

RESUMO

BACKGROUND: Guideline utilization aims at improvement in quality of care and better health outcomes. The objective of the current study was to determine the effect of provider complete adherence to the first antenatal care guidelines on the risk of maternal and neonatal complications in a low resource setting. METHODS: Women delivering in 11 health facilities in the Greater Accra region of Ghana were recruited into a cohort study. Their first antenatal visit records were reviewed to assess providers' adherence to the guidelines, using a thirteen-point checklist. Information on their socio-demographic characteristics and previous pregnancy history was collected. Participants were followed up for 6 weeks post-partum to complete data collection on outcomes. The incidence of maternal and neonatal complications was estimated. The effects of complete adherence on risk of maternal and neonatal complications were estimated and expressed as relative risks (RRs) with their 95% confidence intervals (CI) adjusted for a potential clustering effect of health facilities. RESULTS: Overall, 926 women were followed up to 6 weeks post-partum. Mean age (SD) of participants was 28.2 (5.4) years. Complete adherence to guidelines pertained to the care of 48.5% of women. Incidence of preterm deliveries, low birth weight, stillbirths and neonatal mortality were 5.3, 6.1, 0.4 and 1.4% respectively. Complete adherence to the guidelines decreased risk of any neonatal complication [0.72 (0.65-0.93); p = 0.01] and delivery complication [0.66 (0.44-0.99), p = 0.04]. CONCLUSION: Complete provider adherence to antenatal care guidelines at first antenatal visit influences delivery and neonatal outcomes. While there is the need to explore and understand explanatory mechanisms for these observations, programs that promote complete adherence to guidelines will improve the pregnancy outcomes.

RESUMO

BACKGROUND: Stillbirth is a major contributor to perinatal mortality and it is particularly common in low- and middle-income countries, where annually about three million stillbirths occur in the third trimester. This study aims to develop a prediction model for early detection of pregnancies at high risk of stillbirth. METHODS: This retrospective cohort study examined 6,573 pregnant women who delivered at Federal Medical Centre Bida, a tertiary level of healthcare in Nigeria from January 2010 to December 2013. Descriptive statistics were performed and missing data imputed. Multivariable logistic regression was applied to examine the associations between selected candidate predictors and stillbirth. Discrimination and calibration were used to assess the model's performance. The prediction model was validated internally and over-optimism was corrected. RESULTS: We developed a prediction model for stillbirth that comprised maternal comorbidity, place of residence, maternal occupation, parity, bleeding in pregnancy, and fetal presentation. As a secondary analysis, we extended the model by including fetal growth rate as a predictor, to examine how beneficial ultrasound parameters would be for the predictive performance of the model. After internal validation, both calibration and discriminative performance of both the basic and extended model were excellent (i.e. C-statistic basic model = 0.80 (95 % CI 0.78-0.83) and extended model = 0.82 (95 % CI 0.80-0.83)). CONCLUSION: We developed a simple but informative prediction model for early detection of pregnancies with a high risk of stillbirth for early intervention in a low resource setting. Future research should focus on external validation of the performance of this promising model.

RESUMO

BACKGROUND: Lack of resources has been identified as a reason for non-adherence to clinical guidelines. Our aim was to describe public health facility resource availability in relation to provider adherence to first antenatal visit guidelines. METHODS: A cross-sectional analysis of the baseline data of a prospective cohort study on adherence to first antenatal care visit guidelines was carried out in 11 facilities in the Greater Accra Region of Ghana. Provider adherence was studied in relation to health facility resource availability such as antenatal workload for clinical staffs, routine antenatal drugs, laboratory testing, protocols, ambulance and equipment. RESULTS: Eleven facilities comprising 6 hospitals (54.5 %), 4 polyclinics (36.4 %) and 1 health center were randomly sampled. Complete provider adherence to first antenatal guidelines for all the 946 participants was 48.1 % (95 % CI: 41.8-54.2 %), varying significantly amongst the types of facilities, with highest rate in the polyclinics. Average antenatal workload per month per clinical staff member was higher in polyclinics compared to the hospitals. All facility laboratories were able to conduct routine antenatal tests. Most routine antenatal drugs were available in all facilities except magnesium sulphate and sulphadoxine-pyrimethamine which were lacking in some. Antenatal service protocols and equipment were also available in all facilities. CONCLUSION: Although antenatal workload varies across different facility types in the Greater Accra region, other health facility resources that support implementation of first antenatal care guidelines are equally available in all the facilities. These factors therefore do not adequately account for the low and varying proportions of complete adherence to guidelines across facility types. Providers should be continually engaged for a better understanding of the barriers to their adherence to these guidelines.

RESUMO

BACKGROUND: Low- and middle-income countries (LMICs) face the highest burden of maternal and neonatal deaths. Concurrently, they have the lowest number of physicians. Innovative methods such as the exchange of health-related information using mobile devices (mHealth) may support health care workers in the provision of antenatal, delivery, and postnatal care to improve maternal and neonatal outcomes in LMICs. OBJECTIVE: We conducted a systematic review evaluating the effectiveness of mHealth interventions targeting health care workers to improve maternal and neonatal outcomes in LMIC. METHODS: The Cochrane Library, PubMed, EMBASE, Global Health Library, and Popline were searched using predetermined search and indexing terms. Quality assessment was performed using an adapted Cochrane Risk of Bias Tool. A strength, weakness, opportunity, and threat analysis was performed for each included paper. RESULTS: A total of 19 studies were included for this systematic review, 10 intervention and 9 descriptive studies. mHealth interventions were used as communication, data collection, or educational tool by health care providers primarily at the community level in the provision of antenatal, delivery, and postnatal care. Interventions were used to track pregnant women to improve antenatal and delivery care, as well as facilitate referrals. None of the studies directly assessed the effect of mHealth on maternal and neonatal mortality. Challenges of mHealth interventions to assist health care workers consisted mainly of technical problems, such as mobile network coverage, internet access, electricity access, and maintenance of mobile phones. CONCLUSIONS: mHealth interventions targeting health care workers have the potential to improve maternal and neonatal health services in LMICs. However, there is a gap in the knowledge whether mHealth interventions directly affect maternal and neonatal outcomes and future research should employ experimental designs with relevant outcome measures to address this gap.

RESUMO

BACKGROUND: Neonatal mortality is a global challenge; identification of individual and community determinants associated with it are important for targeted interventions. However in most low and middle income countries (LMICs) including Ghana this problem has not been adequately investigated as the impact of contextual factors remains undetermined despite their significant influence on under-five mortality and morbidity. METHODS: Based on a modified conceptual framework for child survival, hierarchical modelling was deployed to examine about 6,900 women, aged 15 - 49 years (level 1), nested within 412 communities (level 2) in Ghana by analysing combined data of the 2003 and 2008 Ghana Demographic and Health Survey. The aim was to identify individual (maternal, paternal, neonatal, antenatal, delivery and postnatal) and community (socioeconomic disadvantage communities) determinants associated with neonatal mortality. RESULTS: The results showed both individual and community characteristics to be associated with neonatal mortality. Infants of multiple-gestation [OR 5.30; P-value < 0.001; 95% CI 2.81 - 10.00], neonates with inadequate birth spacing [OR 3.47; P-value < 0.01; 95% CI 1.60 - 7.57] and low birth weight [OR 2.01; P-value < 0.01; 95% CI 1.23 - 3.30] had a lower chance of surviving the neonatal period. Similarly, infants of grand multiparous mothers [OR 2.59; P-value < 0.05; 95% CI 1.03 - 6.49] and non-breastfed infants [OR 142.31; P-value < 0.001; 95% CI 80.19 - 252.54] were more likely to die during neonatal life, whereas adequate utilization of antenatal, delivery and postnatal health services [OR 0.25; P-value < 0.001; 95% CI 0.13 - 0.46] reduced the likelihood of neonatal mortality. Dwelling in a neighbourhood with high socioeconomic deprivation was associated with increased neonatal mortality [OR 3.38; P-value < 0.01; 95% CI 1.42 - 8.04]. CONCLUSION: Both individual and community characteristics show a marked impact on neonatal survival. Implementation of community-based interventions addressing basic education, poverty alleviation, women empowerment and infrastructural development and an increased focus on the continuum-of-care approach in healthcare service will improve neonatal survival.

RESUMO

BACKGROUND: Individual attitudes and more general attitudes in society can negatively influence the functioning of people with communication disorders according to the World Health Organisation's (WHO) International Classification of Functioning, Disability, and Health (ICF) (2002). Personal narratives have been recommended as the best means to convey and understand a person's life experience and have been investigated extensively. Investigations of personal narratives of communication impairment in mass media continue to be relatively rare in the literature. Published narratives can enrich understandings of clients' experiences by elucidating available representations of lived experiences of communication impairment. AIMS: To answer the following research questions: What types of personal narratives of communication impairments are currently being disseminated in Irish newspapers? How are experiences of communication impairments represented in these narratives? METHODS & PROCEDURES: The study was qualitative, deploying inductive analysis and drawing on Frank's (1995) typology of illness narratives to analyse narratives that were published in two Irish national newspapers over a 12-month period. OUTCOMES & RESULTS: The results illustrate the under-representation of communication impairments in Irish newspapers as ten out of 51 narratives in the corpus pertained to conditions that may have associated communication impairments. None of the narratives related the lived experience of a person with communication impairment in depth. A combination of quest and chaos narrative types was identified in six out of the ten narratives. Three out of the ten narratives featured a combination of chaos and restitution narrative types. One narrative was identified as being entirely a quest narrative. Three narratives contained elements of restitution. Inductive analysis revealed six main themes in the data (two for each narrative type) with one sub-theme identified for each main theme. The six main themes are: positive stances, re-evaluation of life, despair, fear, hope and support of others. CONCLUSIONS & IMPLICATIONS: The under-representation of the lived experience of people with communication impairments in Irish national newspapers may be seen as contributing to a general lack of understanding and awareness of communication impairments. This under-representation, coupled with a lack of awareness, may potentially affect the ability of people with communication impairments to re-engage with and reintegrate into their communities.

RESUMO

Toxoplasma gondii infection of swine is a potential public health concern because it can be acquired by humans through the handling and consumption of contaminated raw meat. Infections in immunocompromised individuals and fetuses are the most severe and these individuals are most likely to develop clinical toxoplasmosis. Since Mississippians consume a lot of pork, there was a significant need to know the extent to which it poses a health problem in the State. This study focused on the southwestern region of Mississippi. Between July 2003 and March 2004, blood samples were collected from slaughterhouses in southwestern Mississippi and the Alcorn State University swine farm in Churchill, Mississippi. The collected blood samples were centrifuged and the sera were collected, labeled, and stored in a freezer at -20 C. The modified agglutination test was performed at dilutions of 1:25, 1:50, and 1:500. A titer of 25 was considered seropositive. Of a total of 302 samples tested, 48 (16%) were positive at a titer of 25; 29 (10%) were positive at 50; 11 (4%) were positive at 500. The seroprevalence of T. gondii in pigs in southwestern Mississippi is not as high as previous studies done in Mississippi. This could be attributed to the sample size. However, the potential for infection still exists.

RESUMO

Globally, the incidence of hypertensive disorders of pregnancy, especially preeclampsia, remains high, particularly in low- and middle-income countries. The burden of adverse maternal and perinatal outcomes is particularly high for women who develop a hypertensive disorder remote from term (<34 weeks). In parallel, many women have a suboptimal experience of care. To improve the quality of care in terms of provision and experience, there is a need to support the communication of risks and making of treatment decision in ways that promote respectful maternity care. Our study objective is to co-create a tool(kit) to support clinical decision-making, communication of risks and shared decision-making in preeclampsia with relevant stakeholders, incorporating respectful maternity care, justice, and equity principles. This qualitative study detailing the exploratory phase of co-creation takes place over 17 months (Nov 2021-March 2024) in the Greater Accra and Eastern Regions of Ghana. Informed by ethnographic observations of care interactions, in-depth interviews and focus group and group discussions, the tool(kit) will be developed with survivors and women with hypertensive disorders of pregnancy and their families, health professionals, policy makers, and researchers. The tool(kit) will consist of three components: quantitative predicted risk (based on external validated risk models or absolute risk of adverse outcomes), risk communication, and shared decision-making support. We expect to co-create a user-friendly tool(kit) to improve the quality of care for women with preeclampsia remote from term which will contribute to better maternal and perinatal health outcomes as well as better maternity care experience for women in Ghana.


Adverse maternal and perinatal outcomes is high for women who develop preeclampsia remote from term (<34 weeks). To improve the quality of provision and experience of care, there is a need to support communication of risks and treatment decisions that promotes respectful maternity care.This article describes the methodology deployed to cocreate a user-friendly tool(kit) to support risk communication and shared decision-making in the context of severe preeclampsia in a low resource setting.

RESUMO

Autism spectrum disorders (ASD) are characterized by impairments in reciprocal social communication, and repetitive, stereotyped verbal and non-verbal behaviors. Genetic studies have provided a relatively large number of genes that constitute a comprehensive framework to better understand this complex and heterogeneous syndrome. Based on the most robust findings, three observations can be made. First, genetic contributions to ASD are highly heterogeneous and most probably involve a combination of alleles with low and high penetrance. Second, the majority of the mutations apparently affect a single allele, suggesting a key role for gene dosage in susceptibility to ASD. Finally, the broad expression and function of the causative genes suggest that alteration of synaptic homeostasis could be a common biological process associated with ASD. Understanding the mechanisms that regulate synaptic homeostasis should shed new light on the causes of ASD and could provide a means to modulate the severity of the symptoms.

RESUMO

BACKGROUND: Widespread abnormalities in white matter development are frequently reported in cases of autism spectrum disorders (ASD) and could be involved in the disconnectivity suggested in these disorders. Homozygous mutations in the gene coding for fatty-acid 2-hydroxylase (FA2H), an enzyme involved in myelin synthesis, are associated with complex leukodystrophies, but little is known about the functional impact of heterozygous FA2H mutations. We hypothesized that rare deleterious heterozygous mutations of FA2H might constitute risk factors for ASD. METHODS: We searched deleterious mutations affecting FA2H, by genotyping 1256 independent patients with ASD genotyped using Genome Wide SNP arrays, and also by sequencing in independent set of 186 subjects with ASD and 353 controls. We then explored the impact of the identified mutations by measuring FA2H enzymatic activity and expression, in transfected COS7 cells. RESULTS: One heterozygous deletion within 16q22.3-q23.1 including FA2H was observed in two siblings who share symptoms of autism and severe cognitive impairment, axial T2-FLAIR weighted MRI posterior periventricular white matter lesions. Also, two rare non-synonymous mutations (R113W and R113Q) were reported. Although predictive models suggested that R113W should be a deleterious, we did not find that FA2H activity was affected by expression of the R113W mutation in cultured COS cells. CONCLUSIONS: While our results do not support a major role for FA2H coding variants in ASD, a screening of other genes related to myelin synthesis would allow us to better understand the role of non-neuronal elements in ASD susceptibility.
