    Background: Spices have a long history of both culinary use and health benefits. Ethnic spices are spices specific to a particular geographic location. In Ghana, there are varying perceptions and uses of ethnic spices which are mostly not documented. Objective: To assess the use and perceived health benefits of ethnic spices among women in Accra, Ghana. Methods: A cross-sectional study was conducted among 370 women in randomly selected churches in Accra, Ghana. A semi-structured questionnaire was used to obtain sociodemographic data and information on ethnic spice use. Chi-square test was used to determine the association between socio-demographic characteristics of participants and perceived health benefits of ethnic spice usage. Results: The most commonly consumed spices out of the 19 spices explored in this study were onion (98.4%), garlic (97.6%), ginger (96.8%) and chili pepper (84.1%). Majority of the participants perceived ginger (74.6%) and garlic (73.8%) as having health benefits. Age (p=.001) and self-reported health status (p=0.010) were significantly associated with perceived health benefits of the spices. Conclusion: Onion, garlic, ginger and chili pepper were the four most commonly consumed ethnic spices. Age and self-reported health status of participants influenced perceived health benefits of ethnic spice usage. Keywords: Spices; health benefits; perception; flavour

    Malnutrition is highly prevalent in developing countries. Children are at high nutritional risk of being malnourished because of their physiological demands at this age. However, the nutritional status of school age children is poorly documented in Ghana. The aim of this study was to assess and compare the nutritional status of boarding and non-boarding pupils aged 8 to 10 years in the Accra Metropolis, Ghana. A cross-sectional study was conducted among 124 children in three private schools which have boarding facilities (optional) in the Accra Metropolis, Ghana. Dietary intakes of children between the ages of 8 and 10 years were assessed using a two-day 24 hour recall.  Weight and height measurements were taken. WHO Anthroplus software was used to determine WAZ, HAZ and BAZ. Ghanaian food composition tables were used to calculate the nutritional components of foods eaten by subjects. T-tests were used to analyse differences between variables. The prevalence of stunting, underweight, overweight and obesity among the children were 0.8%, 0.8%, 12.1% and 11.3% respectively. The total energy and nutrient intake of calcium among children (both boarders and non-boarders) was inadequate. There was no significant difference in the nutritional status and mean nutrient intake between boarding and non-boarding children. Nutritional status between boarders and non boarders were found to be similar. Key words: School children, boarders, non-boarders, Ghanaian, nutritional statu

    Single-agent MOR208 salvage and maintenance therapy in a patient with refractory/relapsing diffuse large B-cell lymphoma : a case report

    Get PDF
    Background: Diffuse large B-cell lymphoma is the most common subtype of non-Hodgkin’s lymphoma. Standard first-line treatment for this aggressive subtype comprises the anti-CD20 antibody rituximab combined with cyclophosphamide, doxorubicin, vincristine, and prednisone. If patients receiving such treatment have an early relapse, or their disease is initially refractory to such treatment, standard salvage regimens may not be effective. There is therefore a high unmet clinical need for new targeted agents that might improve the outcome for such patients. CD19 is a B-lymphocyte lineage-specific cell surface antigen that is expressed by most B-cell non-Hodgkin's lymphomas. MOR208 is an fragment-crystallizable engineered humanized monoclonal antibody with enhanced antitumor activity that targets CD19 and that may consequently have clinical utility in this setting. Case presentation: We describe the case of a 33-year-old Caucasian man who presented with a 3-month history of general symptoms and who was admitted to our pulmonology ward with dyspnea due to pneumonia and severe anemia. A histopathological examination of an enlarged right suprasternal lymph node confirmed a diagnosis of T-cell/ histiocyte-rich large B-cell lymphoma, an uncommon morphological variant of diffuse large B-cell lymphoma. Our patient had a complete response to first-line rituximab combined with cyclophosphamide, doxorubicin, vincristine, and prednisone, but had an early relapse 5 months after the end of treatment. After intensive salvage therapy consolidated with an autologous stem-cell transplant, our patient again had an early relapse and was subsequently enrolled in a phase IIa trial of single-agent MOR208. Following a scheduled 3 months of weekly treatment, a partial response was confirmed and MOR208 was continued as maintenance therapy, with administration every second week. Positron emission tomography-computed tomography confirmed a complete response 9 months later. This response is ongoing, with a duration of 24 months. MOR208 was well-tolerated by our patient and his quality of life and performance status remain high. No hospitalizations were required and our patient engaged in full-time work and physical activities. Conclusion: Third-line single-agent therapy with the CD19 antibody MOR208 was highly effective in this patient, despite a history of early relapse after standard first-line and second-line treatment regimens. These data provide support for future randomized studies of MOR208

    The Genetic Basis of Moyamoya Disease

    Moyamoya disease (MMD) is a rare cerebrovascular disease characterized by progressive spontaneous bilateral occlusion of the intracranial internal cerebral arteries (ICA) and their major branches with compensatory capillary collaterals resembling a "puff of smoke" (Japanese: Moyamoya) on cerebral angiography. These pathological alterations of the vessels are called Moyamoya arteriopathy or vasculopathy and a further distinction is made between primary and secondary MMD. Clinical presentation depends on age and population, with hemorrhage and ischemic infarcts in particular leading to severe neurological dysfunction or even death. Although the diagnostic suspicion can be posed by MRA or CTA, cerebral angiography is mandatory for diagnostic confirmation. Since no therapy to limit the stenotic lesions or the development of a collateral network is available, the only treatment established so far is surgical revascularization. The pathophysiology still remains unknown. Due to the early age of onset, familial cases and the variable incidence rate between different ethnic groups, the focus was put on genetic aspects early on. Several genetic risk loci as well as individual risk genes have been reported; however, few of them could be replicated in independent series. Linkage studies revealed linkage to the 17q25 locus. Multiple studies on the association of SNPs and MMD have been conducted, mainly focussing on the endothelium, smooth muscle cells, cytokines and growth factors. A variant of the RNF213 gene was shown to be strongly associated with MMD with a founder effect in the East Asian population. Although it is unknown how mutations in the RNF213 gene, encoding for a ubiquitously expressed 591 kDa cytosolic protein, lead to clinical features of MMD, RNF213 has been confirmed as a susceptibility gene in several studies with a gene dosage-dependent clinical phenotype, allowing preventive screening and possibly the development of new therapeutic approaches. This review focuses on the genetic basis of primary MMD only

    Distinct Immune Profiles of Exhausted Effector and Memory CD8+ T Cells in Individuals With Filarial Lymphedema

    CD8+ T cells are crucial for the clearance of viral infections, and current research begins to highlight their importance in parasitic diseases too. In-depth research about characteristics of CD8+ T-cell subsets and exhaustion remains uncertain, especially during filariasis, a chronic helminth infection. Lymphatic filariasis, elicited by Wuchereria bancrofti, remains a serious health problem in endemic areas in Ghana, especially in those suffering from morbidity due to lymphedema (LE). In this observational study, the characteristics and profiles of CD8+ T cells were compared between asymptomatic Wuchereria bancrofti-infected individuals, uninfected endemic normals, and those with LE (grades 2–6). Focusing on exhausted memory (CD8+exmem: CD8+ T-betdimEomeshi) and effector (CD8+exeff: CD8+T-bethiEomesdim) CD8+ T-cell subsets, advanced flow cytometry revealed that LE individuals presented reduced frequencies of IFN-γ+CD8+exmem T cells expressing Tim-3 or LAG-3 which negatively correlated to the presence of LE. Moreover, the LE cohort further showed significantly higher frequencies of IL-10+CD8+exeff T cells expressing either Tim-3, LAG-3, CD39, KLRG-1, or PD-1, all associated markers of exhaustion, and that these frequencies positively correlated with the presence of LE. In summary, this study shows that distinct exhausted CD8+ T-cell subsets are prominent in individuals suffering from LE, suggesting that enhanced inflammation and constant immune activation might drive exhaustion of CD8+ T cells. Since T-cell exhaustion is known to be associated with insufficient control of persisting antigen, the data presented here reveals that these CD8+ T-cell exhaustion patterns in filarial LE should be taken into consideration for prevention and control management of LE

    Introduction Newborn babies who require admission for specialist care can experience immediate and sometimes lasting impacts. For babies admitted to special care nurseries (SCN), there is no dataset comparable to that of the Australian and New Zealand Neonatal Network (ANZNN), which has helped improve the quality and consistency of neonatal intensive care through standardised data collection. Objectives We aim to establish a proof-of-concept, Victoria-wide registry of babies admitted to SCN, embedded within the whole-of-Victoria Generation Victoria (GenV) cohort. Methods This prototype registry is a depth sub-cohort nested within GenV, targeting all babies born in Victoria from Oct-2021 to Oct-2023. Infants admitted to SCN are eligible. The minimum dataset will be harmonised with ANZNN for common constructs but also include SCN-only items, and will cover maternal, antenatal, newborn, respiratory/respiratory support, cardiac, infection, nutrition, feeding, cerebral and other items. As well as the dataset, this protocol outlines the anticipated cohort, timeline for this registry, and how this will serve as a resource for longitudinal research through its integration with the GenV longitudinal cohort and linked datasets. Conclusion The registry will provide the opportunity to better understand the health and future outcomes of the large and growing cohort of children that require specialist care after birth. The data would generate translatable evidence and could lay the groundwork for a stand-alone ongoing clinical quality registry post-GenV

    Objectives To investigate the additional programme cost and cost-effectiveness of ‘right@home’ Nurse Home Visiting (NHV) programme in relation to improving maternal and child outcomes at child age 3 years compared with usual care. Design A cost–utility analysis from a government-as-payer perspective alongside a randomised trial of NHV over 3-year period. Costs and quality-adjusted lifeyears (QALYs) were discounted at 5%. Analysis used an intention-to-treat approach with multiple imputation. Setting The right@home was implemented from 2013 in Victoria and Tasmania states of Australia, as a primary care service for pregnant women, delivered until child age 2 years. Participants 722 pregnant Australian women experiencing adversity received NHV (n=363) or usual care (clinic visits) (n=359). Primary and secondary outcome measures First, a cost–consequences analysis to compare the additional costs of NHV over usual care, accounting for any reduced costs of service use, and impacts on all maternal and child outcomes assessed at 3 years. Second, cost–utility analysis from a government-as-payer perspective compared additional costs to maternal QALYs to express cost-effectiveness in terms of additional cost per additional QALY gained. Results When compared with usual care at child age 3 years, the right@home intervention cost A7685extraperwoman(95A7685 extra per woman (95%CI A7006 to A8364)andgenerated0.01moreQALYs(95A8364) and generated 0.01 more QALYs (95%CI −0.01 to 0.02). The probability of right@home being cost-effective by child age 3 years is less than 20%, at a willingness-to-pay threshold of A50 000 per QALY. Conclusions Benefits of NHV to parenting at 2 years and maternal health and well-being at 3 years translate into marginal maternal QALY gains. Like previous cost-effectiveness results for NHV programmes, right@home is not cost-effective at 3 years. Given the relatively high up-front costs of NHV, long-term follow-up is needed to assess the accrual of health and economic benefits over time

    Real-life experiences of letermovir prophylaxis for cytomegalovirus infection in patients after hematopoietic stem cell transplantation: Polish Acute Leukemia Group (PALG) analysis

    Get PDF
    Introduction: Letermovir (LMV) is a new, cytomegalovirus (CMV)-specific, antiviral drug, approved in 2018 for CMV prophylaxis in patients after allogeneic hematopoietic transplantation. The introduction of letermovir prophylaxis has changed the management of CMV infection: it has reduced the incidence of CMV infections and CMV-related complications, and also improved the overall survival in CMV seropositive patients. However, until recently, due to its high treatment cost, prophylaxis with letermovir has not beeen a standard of care in Poland. Material and methods: To confirm the effectiveness and safety of letermovir prophylaxis, we collected real-life data from eight Polish transplant centers, in which a total of 53 patients were treated with letermovir, including off-label use. Results: LMV is characterized by low toxicity and good tolerability. There were no reports of special adverse events caused by LMV. Conclusions: Our experiences confirm the effectiveness and safety of letermovir prophylaxis, and suggest that this prophylaxis should be started as soon as possible after the infusion of stem cells, preferably no later than day 14. Moreover, our findings indicate that some patients could benefit from extended letermovir prophylaxis beyond 100 days after transplant
