Penetrating abdominal injuries in adults seen at two teaching hospitals in Ghana

Background: The incidence of penetrating abdominal injuries (PAI) has increased in the West African sub-region.Objective: To determine the pattern and management outcome of penetrating abdominal injuries (PAI) in the two main teaching hospitals in Ghana.Study Design: A prospective and retrospective descriptive study.Setting: Komfo Anokye Teaching Hospital (KATH), Kumasi and Korle-Bu Teaching Hospital (KBTH), Accra.Methods: Relevant details of all adult patients admitted with penetrating abdominal injuries over a 11-year period were recorded at KATH and KBTH in Accra. The study in KATH was prospective pro forma based and that in the KBTH was a retrospective case review of all penetrating abdominal injuries.Results: There were 411 patients, mostly men (M: F-8:1). The peak age of patients was 20-29 years, 164 patients (39.9%). Abdominal stab wound injuries accounted for 251 (61.1%). Three hundred and thirty – one patients (80.5%) had an emergency laparotomy. Twelve patients required 16 emergency thoracotomies. The small bowel (23.2%), stomach (12.9%), colon (10.2%), the liver (10.0%), were the most commonly injured organs. In 92 patients (29.0%) no significant intra-abdominal injury was detected at laparotomyConclusion: Stab wounds are the main penetrating abdominal injuries seen mostly among young male adults in Ghana. Management was by a mandatory laparotomy after clinical assessment. The overall mortality was 4.4%. Selective non-operative management of abdominal stab wounds is possible

Implementing the Ahafo Benefit Agreements: Seeking Meaningful Community Participation at Newmont’s Ahafo Gold Mine in Ghana

In 2008, ten communities in the Brong Ahafo region of Ghana entered into agreements with Newmont Ghana to govern company-community relations, ensure local job creation, and share the benefits of the company’s mining operations. Ten years later, this report, co-authored by Canadian International Resources and Development Institute (CIRDI), African Center for Energy Policy (ACEP), CCSI, and ISP, looks at the communities’ experience of those agreements and suggests how the agreements might be improved. Though the agreements were celebrated for their attempts to include all stakeholders in decision-making, challenges remain around representation, consultation, and participation. New entities established to facilitate multi-stakeholder decision-making have led to the replication of existing power imbalances. And despite many improvements, the agreements have not fully stabilized company-community relations; tensions and grievances remain concerning employment, compensation, and resettlement, among other issues. The report makes research-informed recommendations for the communities, Newmont Ghana, and other stakeholders in the lead-up to the renegotiation of the agreements. While the negotiation of benefit agreements (sometimes called “Community Development Agreements”) have been the subject of wide-ranging research, academic literature on agreement implementation is still relatively sparse, and tends to focus on cases in Australia and Canada, with little information available from cases in low- or middle-income countries. This report therefore seeks to contribute to filling this gap, alongside other studies mentioned in the report. The report was published on July 25, 2018. On that day, ACEP presented the report and a Twi-translation of the executive summary to representatives and opinion leaders from the communities. ACEP also led a workshop both on the report and on benefit agreements more generally

Surveillance of viral haemorrhagic fevers in Ghana: entomological assessment of the risk of transmission in the northern regions

Objectives: To assess the risk of transmission of viral haemorrhagic fevers in northern Ghana. Design: A two-year cross-sectional entomological study was carried out in four communities in thenorthern part of Ghana. Standard WHO methods were used to collect adult and larvae of Aedes mosquitoes to estimate man-vector contact rates and larval indices. Results: A total of 2804 households were surveyed to estimate larval indices and man-vector contacts of potential vectors of viral haemorrhagic fevers such as Yellow fever and Dengue. Over 56% households in each study site were positivefor Aedes larvae. Relatively higher Breteaux index (BI) and Container index (CI) were estimated in Damongo (BI: 180 and CI: 44.8) and Jirapa (BI: 149.7 and CI: 41.5) compared to Tumu (BI: 76.1and CI: 19.5) and Bolgatanga (BI: 72.4 and CI: 20.6). Man-biting rates of 9.8 and 18.5 bites /man/hour were estimated for Damongo and Jiraparespectively whilst Bolgatanga recorded 10 B/M/H. Generally, man-vector contact rates in all the study sites were higher during the dry season than the wet season. Larval indices showed seasonalvariations and the dry season was identified as the high-risk period for transmission of viral haemorrhagic fevers and possible disease outbreaks. No flavivirus was detected in the 2034 Aedes mosquitoes from the study sites by RTPCR. Conclusions: Aedes mosquito larval densities and adult biting rates, in all the study areas were sufficientto promote outbreaks of viral haemorrhagic fevers

Targeted Selection of Stimulation Parameters for Restoration of Motor and Autonomic Function in Individuals With Spinal Cord Injury

Study Design: This is a report of methods and tools for selection of task and individual configurations targeted for voluntary movement, standing, stepping, blood pressure stabilization, and facilitation of bladder storage and emptying using tonic-interleaved excitation of the lumbosacral spinal cord. Objectives: This study aimed to present strategies used for selection of stimulation parameters for various motor and autonomic functions. Conclusions: Tonic-interleaved functionally focused neuromodulation targets a myriad of consequences from spinal cord injury with surgical implantation of the epidural electrode at a single location. This approach indicates the sophistication of the human spinal cord circuitry and its important role in the regulation of motor and autonomic functions in humans

In utero exposure to malaria is associated with metabolic traits in adolescence: The Agogo 2000 birth cohort study.

OBJECTIVES: Malaria in pregnancy (MiP) contributes to fetal undernutrition and adverse birth outcomes, and may constitute a developmental origin of metabolic diseases in the offspring. In a Ghanaian birth cohort, we examined the relationships between MiP-exposure and metabolic traits in adolescence. METHODS: MiP at delivery was assessed in 155 mother-child pairs. Among the now teenaged children (mean age, 14.8 years; 53% male), we measured fasting plasma glucose (FPG), body mass index (BMI), and systolic and diastolic blood pressure (BP). Associations of MiP with the adolescents' FPG, BMI, and BP were examined by linear regression. RESULTS: At delivery, 45% were MiP-exposed, which increased FPG in adolescence, adjusted for mother's age at delivery, parity and familial socio-economic status (infected vs. uninfected: mean ΔFPG = 0.20 mmol/L; 95% confidence interval (CI): 0.01, 0.39; p = 0.049). As a trend,this was discernible for BP, particularly for microscopic infections (mean Δsystolic BP = 5.43 mmHg; 95% CI: 0.00, 10.88; p = 0.050; mean Δdiastolic BP = 3.67 mmHg; 95% CI: -0.81, 8.14; p = 0.107). These associations were largely independent of birth weight, gestational age and teenage BMI. Adolescent BMI was not related to MiP. CONCLUSIONS: In rural Ghana, exposure to malaria during fetal development contributes to metabolic conditions in young adulthood

Spinal Cord Imaging Markers and Recovery of Volitional Leg Movement With Spinal Cord Epidural Stimulation in Individuals With Clinically Motor Complete Spinal Cord Injury

Previous studies have shown that epidural stimulation of the lumbosacral spinal cord (scES) can re-enable lower limb volitional motor control in individuals with chronic, clinically motor complete spinal cord injury (SCI). This observation entails that residual supraspinal connectivity to the lumbosacral spinal circuitry still persisted after SCI, although it was non-detectable when scES was not provided. In the present study, we aimed at exploring further the mechanisms underlying scES-promoted recovery of volitional lower limb motor control by investigating neuroimaging markers at the spinal cord lesion site via magnetic resonance imaging (MRI). Spinal cord MRI was collected prior to epidural stimulator implantation in 13 individuals with chronic, clinically motor complete SCI, and the spared tissue of specific regions of the spinal cord (anterior, posterior, right, left, and total cord) was assessed. After epidural stimulator implantation, and prior to any training, volitional motor control was evaluated during left and right lower limb flexion and ankle dorsiflexion attempts. The ability to generate force exertion and movement was not correlated to any neuroimaging marker. On the other hand, spared tissue of specific cord regions significantly and importantly correlated with some aspects of motor control that include activation amplitude of antagonist (negative correlation) muscles during left ankle dorsiflexion, and electromyographic coordination patterns during right lower limb flexion. The fact that amount and location of spared spinal cord tissue at the lesion site were not related to the ability to generate volitional lower limb movements may suggest that supraspinal inputs through spared spinal cord regions that differ across individuals can result in the generation of lower limb volitional motor output prior to any training when epidural stimulation is provided

Paradoxical reactions in Buruli ulcer after initiation of antibiotic therapy: Relationship to bacterial load.

BACKGROUND: We investigated the relationship between bacterial load in Buruli ulcer (BU) lesions and the development of paradoxical reaction following initiation of antibiotic treatment. METHODS: This was a longitudinal study involving BU patients from June 2013 to June 2017. Fine needle aspirates (FNA) and swab samples were obtained to establish the diagnosis of BU by PCR. Additional samples were obtained at baseline, during and after treatment (if the lesion had not healed) for microscopy, culture and combined 16S rRNA reverse transcriptase/ IS2404 qPCR assay. Patients were followed up at regular intervals until complete healing. RESULTS: Forty-seven of 354 patients (13%) with PCR confirmed BU had a PR, occurring between 2 and 42 (median 6) weeks after treatment initiation. The bacterial load, the proportion of patients with positive M. ulcerans culture (15/34 (44%) vs 29/119 (24%), p = 0.025) and the proportion with positive microscopy results (19/31 (61%) vs 28/90 (31%), p = 0.003) before initiation of treatment were significantly higher in the PR compared to the no PR group. Plaques (OR 5.12; 95% CI 2.26-11.61; p<0.001), oedematous (OR 4.23; 95% CI 1.43-12.5; p = 0.009) and category II lesions (OR 2.26; 95% CI 1.14-4.48; p = 0.02) were strongly associated with the occurrence of PR. The median time to complete healing (28 vs 13 weeks, p <0.001) was significantly longer in the PR group. CONCLUSIONS: Buruli ulcer patients who develop PR are characterized by high bacterial load in lesion samples taken at baseline and a higher rate of positive M. ulcerans culture. Occurrence of a PR was associated with delayed healing. TRIAL REGISTRATION: ClinicalTrials.gov NCT02153034
