RESUMO
Parkinson's disease (PD) is a progressive and disabling neurodegenerative disease that rapidly worsens and results in premature mortality if left untreated. Although levodopa is the gold standard treatment for PD globally, its accessibility and affordability are severely limited in low- and middle-income countries worldwide. In this scenario, Mucuna pruriens (MP), a leguminous plant growing wild in tropical regions, emerges as a potential alternative or adjunct to levodopa-based medications due to its cost-effectiveness and global natural availability. Recent studies have demonstrated that MP can significantly ameliorate motor symptoms, although tolerability may vary. The proposition that MP could play a pivotal role in providing affordable and symptomatic relief for PD in low- and middle-income countries is grounded in its promising therapeutic profile, yet caution is warranted until more comprehensive data on the long-term safety and efficacy of MP become available. This manuscript summarizes the knowledge gained about MP by the authors, focusing on how to cultivate, store, and provide it to patients in the safest and most effective way in clinical trials. We aim to increase clinical trials investigating its safety and efficacy in PD, before promoting individual use of MP on a global scale, particularly in countries where availability and affordability of levodopa-based medications is still limited.

Many low-income countries still encounter high mortality rates. The use of maternal health care services is known to be a key intervention in reducing maternal death. Despite investment in the healthcare sector, in 2015 Ghana did not meet the Millennium Development Goal 5 of reducing maternal mortality (MM). The Volta Region registered the highest rate of MM, the lowest percentage of antenatal care (ANC) coverage and the lowest percentage of skilled delivery. This is a qualitative study that used focus group discussions and key-informant interviews to explore the views on pregnancy among rural communities in the Volta Region, identify the barriers in accessing ANC and skilled attendance birth and collect views on how to improve the access to maternal care services.Overall, the study argues that members of the community of the rural villages acknowledge the benefits of ANC and skilled delivery, and the potential risk related to home delivery. However, pregnant women in the Volta Region still encounter different kinds of obstacles that prevent them from seeking maternal health care. These obstacles are driven by social and economic constraints, and by the fact that women may still lack voice in the decision-making process, and by low males' participation.

The natural pattern of progression of Parkinson's disease is largely unknown because patients are conventionally followed on treatment. As Parkinson's disease progresses, the true magnitude of the long-duration response to levodopa remains unknown, because it can only be estimated indirectly in treated patients. We aimed to describe the natural course of motor symptoms by assessing the natural OFF in consecutive Parkinson's disease patients never exposed to treatment (drug-naïve), and to investigate the effects of daily levodopa on the progression of motor disability in the OFF medication state over a 2-year period. In this prospective naturalistic study in sub-Saharan Africa, 30 Parkinson's disease patients (age at onset 58 ± 14 years, disease duration 7 ± 4 years) began levodopa monotherapy and were prospectively assessed using the Unified Parkinson's disease Rating Scale (UPDRS). Data were collected at baseline, at 1-year and 2-years follow-up. First-ever levodopa intake induced a significant improvement in motor symptoms (natural OFF versus ON state UPDRS-III 41.9 ± 15.9 versus 26.8 ± 15.1, respectively; P < 0.001). At 1-year follow-up, OFF state UPDRS-III score after overnight withdrawal of levodopa was considerably lower than natural OFF (26.5 ± 14.9; P < 0 .001). This effect was not modified by disease duration. At the 2-year follow-up, motor signs after overnight OFF (30.2 ± 14.2) were still 30% milder than natural OFF (P = 0.001). The ON state UPDRS-III at the first-ever levodopa challenge was similar to the overnight OFF score at 1-year follow-up and the two conditions were correlated (r = 0.72, P < 0.001). Compared to the natural progression of motor disability, levodopa treatment resulted in a 31% lower annual decline in UPDRS-III scores in the OFF state (3.33 versus 2.30 points/year) with a lower model's variance explained by disease duration (67% versus 36%). Using the equation regressed on pretreatment data, we predicted the natural OFF at 1-year and 2-year follow-up visits and estimated that the magnitude of the long-duration response to levodopa ranged between 60% and 65% of total motor benefit provided by levodopa, independently of disease duration (P = 0.13). Although levodopa therapy was associated with motor fluctuations, overnight OFF disability during levodopa was invariably less severe than the natural course of the disease, independently of disease duration. The same applies to the yearly decline in UPDRS-III scores in the OFF state. Further research is needed to clarify the mechanisms underlying the long-duration response to levodopa in Parkinson's disease. Understanding the natural course of Parkinson's disease and the long-duration response to levodopa may help to develop therapeutic strategies increasing its magnitude to improve patient quality of life and to better interpret the outcome of randomized clinical trials on disease-modifying therapies that still rely on the overnight OFF to define Parkinson's disease progression.

Parkinson's disease (PD) is a progressive, disabling, neurodegenerative disease that requires long term care and pharmaceutical treatment. Levodopa remains the gold standard treatment for PD globally, although it is largely unavailable and unaffordable for the majority of patients in many sub-Saharan African and other low-income countries (LICs). We suggest the potential for Mucuna pruriens (MP), a leguminous plant, to replace or supplement levodopa-based medicines in countries where levodopa is unaffordable and inaccessible due to its low costs of preparation and high natural availability. MP has been shown to induce a great improvement of motor symptoms with few adverse events in recent studies. However, caution is important until more robust data on the long-term safety of MP are available. We believe that MP could potentially be part of the answer to affordable, symptomatic treatment of PD in LICs worldwide.

Empanelment is a foundational strategy for building or improving primary health care systems and a critical pathway for achieving effective universal health coverage. However, there is little international guidance for defining empanelment or understanding how to implement empanelment systems in low- and middle-income countries. To fill this gap, a multi-country collaborative within the Joint Learning Network for Universal Health Coverage developed this empanelment overview, proposing a people-centered definition of empanelment that reflects the responsibility to proactively deliver primary care services to all individuals in a target population. This document, building on existing literature on empanelment and representing input from 10 countries, establishes standard concepts of empanelment and describes why and how empanelment is used. Finally, it identifies key domains that may influence effective empanelment and that must be considered in deciding how empanelment can be implemented. This document is designed to be a useful resource for health policymakers, planners and decision-makers in ministries of health, as well as front line providers of primary care service delivery who are working to ensure quality people-centered primary care to everyone everywhere.
RESUMO
BACKGROUND: There is little data on Trichomonas vaginalis infection in Ghana. This study evaluated the prevalence of trichomoniasis using different diagnostic methods and determined the risk factors for infection in patients. METHODS: A structured questionnaire was administered. Vaginal swabs, urethral swabs and urine specimens were obtained from consenting patients; and the samples processed following standard protocols. The presence of T. vaginalis was determined using wet mount microscopy and polymerase chain reaction (PCR) as gold standard. We also assessed the diagnostic performance the JD's Trichomonas V® rapid antigen test to inform clinical practice. RESULTS: The PCR assay detected T. vaginalis positivity in 64 of 150 patients (42.6, 95%CI:35.0, 50.6) including all positive samples of wet mount microscopy and JD's Trichomonas V® test. Wet mount microscopy showed low sensitivity (31.6%), high specificity (100%), moderate positive predictive value (75.0%), moderate positive likelihood ratio (3.0), and weak agreement (Cohen's kappa, 0.283) with PCR assay. The JD's Trichomonas V® test displayed lower sensitivity (25.0%), specificity (83.3%), and weaker measure of agreement (Cohen's kappa, 0.233) with PCR. In multivariate analysis, the strongest independent predictor for T. vaginalis was female gender [adjusted odds ratio (AOR), 24.89; 95% confidence interval (CI): 10.58, 51.21; P-value< 0.001]. Knowledge of STI showed a protective effect against infection with the parasite (AOR, 0.13; 95%CI: 0.07, 0.29; P-value< 0.017). CONCLUSION: The sensitivity of wet mount microscopy was low for T. vaginalis screening in our region. The JD's Trichomonas V® test should not be considered as an alternative test. We recommend mandatory PCR assay for confirmation of negative wet mount results.

BACKGROUND: Trichomonas vaginalis (TV) infection is the most prevalent non-viral sexually transmitted pathogen worldwide. Among pregnant women, the infection may cause adverse birth outcomes such as premature rupture of membranes and premature labour. In view of the paucity of information relating to TV among Ghanaian pregnant women, this study investigated its prevalence and associated co-infections among pregnant women. METHODS: High vaginal swabs were obtained from 99 pregnant women using sterile cotton swab sticks. Wet preparation, Grams staining, culturing, coagulase and sensitivity testing were carried out to determine the presence of TV and associated microorganisms. RESULTS: The prevalence of TV among the pregnant women was found to be 20.2% (n = 20). Concurring with Trichomoniasis, 75% (n = 15) of participants had other infections such as Candida with prevalence of 53% (n = 8), Proteus infection - 20% (n = 3), Streptococcus infection - 13% (n = 2) and other GNRs and Gonococci having 7% each (n = 1). Moreover, there was 86.9% (n = 86) prevalence of Staphylococcus spp. among study participants. There was statistically significant correlation between TV and Gonococci infection at a correlation co-efficient of 0.107 (P < 0.05) as well as significant correlation between TV and Proteus spp. at a correlation co-efficient of 0.189 (P < 0.05). TV infection was high (60%) among the most sexually active age group (19 to 29 yrs). CONCLUSION: There was 20.2% prevalence of TV among the pregnant women presenting at the hospitals, with Gonococci and Proteus infections being statistically significant associated infections.

PURPOSE: To report the first case of ophthalmia due to contact with cobra venom in the Volta Region, Ghana. METHODS: An ointment containing vitamin A was applied to treat the patient's unilateral defects in the corneal epithelium and the consequent diminished visual acuity. RESULTS: Healing of the corneal epithelium and improvement of visual acuity were observed after only 1 day. CONCLUSIONS: This case suggests that consequences of cases of cobra venom spitting in the eyes can be minimal if immediate treatment is provided.
RESUMO
BACKGROUND: As part of malaria characterization study in the South-Tongu district of Ghana, the current study was conducted to explore relationships between malaria, schistosomiasis, soil transmitted helminths and malnutrition in riparian community settings that had hitherto encountered episodes of mass deworming exercises. METHODS: School-age children were enrolled in a cross-sectional study from April through July 2012. Stool and urine samples were examined respectively for helminths and Schistosoma haematobium. Blood samples were analyzed for malaria parasites and haemoglobin (Hb) concentrations, respectively. Anthropometric indices were measured. Relationships were determined using generalized linear models. RESULTS: The results show low numbers of asymptomatic Plasmodium falciparum (9.2%, n = 37/404) and S. haematobium (2.5%, n = 10/404) infections. The associations between significance terms in the multivariate analysis for P. falciparum infections were further assessed to test the significance of the product terms directly i.e., age in years [adjusted odds ratio (AOR), 3.1; 95% confidence interval (CI) 1.1-5.6], Hb concentration (AOR = 0.71; 95% CI 0.42-2.3), and stunted malnutrition (AOR, 8.72; 95% CI 4.8-25.1). The P. falciparum-associated decrease in mean Hb concentration was 2.82 g/dl (95% CI 1.63-4.1 g/dl; P = 0.001) in stunted children, and 0.75 g/dl (95% CI 1.59-0.085 g/dl; P = 0.076) in the non-stunted cohort. The anaemia-associated decrease in mean parasitaemia in stunted children was 3500 parasites/µl of blood (95% CI 262.46-6737.54 parasites/µl of blood; P = 0.036), and in non-stunted children 2127 parasites/µl of blood (95% CI -0.27 to 4.53; P = 0.085). Stunted malnutrition was the strongest predictor of S. haematobium infection (AOR = 11; 95% CI 3.1-33.6) but significant associations as described for P. falciparum infections were absent. The population attributable risk of anaemia due to P. falciparum was 6.3% (95% CI 2.5-9.3), 0.9% (95% CI 0.4-2.3) for S. haematobium, and 12.5% (95% CI 9.11-19.52) for stunted malnutrition. CONCLUSION: Plasmodium falciparum, S. haematobium, intestinal helminths and their co-infections were uncommon in our school-age children. Stunting exacerbated the extent to which malaria was associated with loss in Hb concentration.

During the past decade, a number of large drug trials suggested that the initiation of levodopa therapy should be delayed to reduce the risk of motor complications in patients with Parkinson's disease. However, the relative contribution of the cumulative exposure to levodopa and of disease progression to the pathophysiology of motor fluctuations and dyskinesias is still poorly understood. In this 4-year multicentre study, we investigated a large cohort of patients with Parkinson's disease in a sub-Saharan African country (Ghana), where access to medication is limited and the initiation of levodopa therapy often occurs many years after onset. The primary objective was to investigate whether the occurrence of motor complications is primarily related to the duration of levodopa therapy or to disease-related factors. Study design included a cross-sectional case-control analysis of data collected between December 2008 and November 2012, and a prospective study of patients followed-up for at least 6 months after the initiation of levodopa therapy. Ninety-one patients fulfilled criteria for clinical diagnosis of idiopathic Parkinson's disease (58 males, mean age at onset 60.6 ± 11.3 years). Demographic data were compared to those of 2282 consecutive Italian patients recruited during the same period, whereas nested matched subgroups were used to compare clinical variables. Demographic features, frequency and severity of motor and non-motor symptoms were comparable between the two populations, with the only exception of more frequent tremor-dominant presentation in Ghana. At baseline, the proportion of Ghanaian patients with motor fluctuations and dyskinesias was 56% and 14%, respectively. Although levodopa therapy was introduced later in Ghana (mean disease duration 4.2 ± 2.8 versus 2.4 ± 2.1 years, P < 0.001), disease duration at the occurrence of motor fluctuations and dyskinesias was similar in the two populations. In multivariate analysis, disease duration and levodopa daily dose (mg/kg of body weight) were associated with motor complications, while the disease duration at the initiation of levodopa was not. Prospective follow-up for a mean of 2.6 ± 1.3 years of a subgroup of 21 patients who were drug-naïve at baseline [median disease duration 4.5 (interquartile range, 2.3-5) years] revealed that the median time to development of motor fluctuations and dyskinesias after initiation of levodopa therapy was 6 months. We conclude that motor fluctuations and dyskinesias are not associated with the duration of levodopa therapy, but rather with longer disease duration and higher levodopa daily dose. Hence, the practice to withhold levodopa therapy with the objective of delaying the occurrence of motor complications is not justified.

OBJECTIVE: Dietary treatment is important for the management of Parkinson's disease (PD). Our objective was to describe the dietary habits and assess the nutritional status of Ghanaian patients with PD. This study is part of a larger project, for which Ghana has been selected as a pilot country. METHODS: Fifty-five Ghanaian patients with PD and 12 healthy Ghanaian controls were recruited. We assessed nutritional status, investigated dietary habits, and assessed the prevalence of the nutritional complications of PD (e.g., constipation and dysphagia). RESULTS: The mean daily caloric intake was about 1200 kcal/d in patients with PD and in controls. The typical diet was based on semisolid foods, usually vegetable soups accompanied by cereal flour or root starch or sometimes chicken or fish. The intake of milk and its derivatives was low. The prevalences of constipation and dysphagia in patients with PD were 49% and 21%, respectively. CONCLUSION: This study has yielded information that could be useful for the study of the management of PD and for the assessment of response to therapy.
