Primary Health Care by Vhembe women in the Limpopo province of South Africa: Knowledge and Practice
Child mortality has increased in South Africa since 1990, despite a national policy of free primary healthcare for pregnant women and children under the age of five years. A significant number of women and children die during childbirth and 40% of stillbirths happen during labour. Lack of sufficient knowledge about primary health care (PHC) is costing South Africa greatly because many of the deaths of mothers, babies and young children could be avoided. Teenagers conceal pregnancy and that adds to higher risk of death among themselves and their unborn babies. Almost a half of all new-born babies die during the first 24 hours of birth, and 75% die in their first week of life. This study looks at primary health care by women in Vhembe by identifying knowledge and skills they possess to deal with health care issues. A 3-stage sample survey was conducted covering all the municipalities in the district. About 2660 women aged between 13 and 50 years were interviewed using structured questionnaire. Applying various statistical methods including logistic and regression modelling, this study shows that majority of the respondents know about PHC and that age and education of women are important factors affecting child’s health and survival in the Vhembe district. If Limpopo wants to reduce childhood mortality, this study recommends that efforts be made to educate women, especially teenagers about primary health care, immunization, oral rehydration therapy and attendance at clinics for pre-natal medical check-ups during pregnancy
Different Crime Types in Western Cape Province: Principal Component Analysis
South Africa has a very high crime rate compared to most countries. Crime affects the society, business and psychology of the people. It compels people to move out or come into a particular area. It is most prevalent in the urban areas where poverty gap is conspicuous. Western Cape and Gauteng Provinces are the best developed provinces in the country and therefore have higher crime levels. But the question is: what types of crime are prevalent in the Western Cape Province? And what are the major causes of these crimes? The purpose of this paper is to identify the different types of crimes committed in the Western Cape Province which are prominent. Principal Component analysis (PCA) has been use in this study to gauge the patterns of crime and the distinct important factors affecting the level of crime. Secondary data from a website have been used in the analysis. The results show that violence and vehicle thefts are the most committed crimes in the province. The areas where crime occurs most frequently are Bellville, Cape Town Central, Gugulethu, Harare, Khayelisha, Mitchells Plain, Nyanga and Parow. Firearms have been identified as major means for committing crime. The paper recommends that attempts be made by the provincial government to clamp down unlicensed fire arm holders/dealers. Amnesty should be granted to encourage holders of unlicensed fire arms to surrender without punishment and the public should report to the police all those dealing in unlicensed firearms in order to root out crime in the province
African Stock Markets and Return Predictability
This article re-examines the return predictability of eight African stock markets. When returns of stocks are predictable, arbitrageurs make abnormal gains from analyzing prices. The study uses a non-parametric Generalised Spectral (GS) test in a rolling window approach. The rolling window approach tracts the periods of efficiency over time. The GS test is robust to conditional heteroscedasticity and it detects the presence of linear and nonlinear dependencies in a stationary time series. Our results support the Adaptive Market Hypothesis (AMH). This is because, indices whose returns were observed to be predictable by analyzing them in absolute form and therefore weak - form inefficient showed trends of unpredictability in a rolling window
Quality of life among cervical cancer patients undergoing radiotherapy.
IntroductionThere has been an increasing rate of the incidence and mortality of cervical cancer in Ghana. Cancer and the treatment's side effects have adverse effects on the patients and this affects patient's well-being and lifestyle during and after radiotherapy. The study sought to assess the impact of demographic and clinical characteristics on Quality of Life (QoL) among cervical cancer patients undergoing radiotherapy in Ghana.MethodsA cross sectional quantitative study design was carried out on 120 cervical cancer patients who were conveniently sampled from the study site. The data was collected between the months of December, 2017 and February, 2018. QoL was measured using the FACT-G questionnaire. The mean scores of QoL were determined, whiles the chi-square test was used to determine the impact of socio-demographic and clinical characteristics on the QoL of the patients.ResultsThe mean age of the patients was 56.8 years. Majority of the patients reported stable QoL. The social well-being of the older patients was more affected than other patients. The unmarried, widows and patients who underwent surgery with radiotherapy were emotionally affected. Majority (56%) of the participants had stable QoL whiles 22% each had poor and good QoL. Significant association was found among 35-39 age group with physical well-being and overall QoL (p=0.017 and 0.029) respectively.ConclusionThere is a need to embrace a QoL assessment instrument in the study site so as to help the oncology team in the identification and addressing of specific indicators that affect the QoL of cervical cancer patients
Financial toxicity of cancer care in low and middle-income countries: a systematic review and meta-analysis
Introduction: The costs associated with cancer diagnosis, treatment and care present enormous financial toxicity. However, evidence of financial toxicity associated with cancer in low and middle-income countries (LMICs) is scarce. Aim: To identify the extent of cancer-related financial toxicity and how it has been measured in LMICs. Methods: : Four electronic databases were searched to identify studies of any design that reported financial toxicity among cancer patients in LMICs. Random-effects meta-analysis was used to derive the pooled prevalence of financial toxicity. Sub-group analyses were performed according to: costs; and determinants of financial toxicity. Results: : A total of 31 studies were included in this systematic review and meta-analysis. The pooled prevalence of financial toxicity was 56.96% [95% CI, 30.51, 106.32]. In sub-group meta-analyses, the financial toxicity was higher among cancer patients with household size of more than four (1.17% [95% CI, 1.03, 1.32]; p = 0.02; I 2 = 0%), multiple cycles of chemotherapy (1.94% [95% CI, 1.00, 3.75]; p = 0.05; I 2 = 43%) and private health facilities (2.87% [95% CI, 1.89, 4.35]; p Conclusions: : This study indicates that cancer diagnosis, treatment and care impose high financial toxicity on cancer patients in LMICs. Further rigorous research on cancer-related financial toxicity is needed
Toxoplasma gondii-Induced Activation of EGFR Prevents Autophagy Protein-Mediated Killing of the Parasite
Toxoplasma gondii resides in an intracellular compartment (parasitophorous vacuole) that excludes transmembrane molecules required for endosome-lysosome recruitment. Thus, the parasite survives by avoiding lysosomal degradation. However, autophagy can re-route the parasitophorous vacuole to the lysosomes and cause parasite killing. This raises the possibility that T. gondii may deploy a strategy to prevent autophagic targeting to maintain the non-fusogenic nature of the vacuole. We report that T. gondii activated EGFR in endothelial cells, retinal pigment epithelial cells and microglia. Blockade of EGFR or its downstream molecule, Akt, caused targeting of the parasite by LC3(+) structures, vacuole-lysosomal fusion, lysosomal degradation and killing of the parasite that were dependent on the autophagy proteins Atg7 and Beclin 1. Disassembly of GPCR or inhibition of metalloproteinases did not prevent EGFR-Akt activation. T. gondii micronemal proteins (MICs) containing EGF domains (EGF-MICs; MIC3 and MIC6) appeared to promote EGFR activation. Parasites defective in EGF-MICs (MIC1 ko, deficient in MIC1 and secretion of MIC6; MIC3 ko, deficient in MIC3; and MIC1-3 ko, deficient in MIC1, MIC3 and secretion of MIC6) caused impaired EGFR-Akt activation and recombinant EGF-MICs (MIC3 and MIC6) caused EGFR-Akt activation. In cells treated with autophagy stimulators (CD154, rapamycin) EGFR signaling inhibited LC3 accumulation around the parasite. Moreover, increased LC3 accumulation and parasite killing were noted in CD154-activated cells infected with MIC1-3 ko parasites. Finally, recombinant MIC3 and MIC6 inhibited parasite killing triggered by CD154 particularly against MIC1-3 ko parasites. Thus, our findings identified EGFR activation as a strategy used by T. gondii to maintain the non-fusogenic nature of the parasitophorous vacuole and suggest that EGF-MICs have a novel role in affecting signaling in host cells to promote parasite survival
Notes for genera: basal clades of Fungi (including Aphelidiomycota, Basidiobolomycota, Blastocladiomycota, Calcarisporiellomycota, Caulochytriomycota, Chytridiomycota, Entomophthoromycota, Glomeromycota, Kickxellomycota, Monoblepharomycota, Mortierellomycota, Mucoromycota, Neocallimastigomycota, Olpidiomycota, Rozellomycota and Zoopagomycota)
Compared to the higher fungi (Dikarya), taxonomic and evolutionary studies on the basal clades of fungi are fewer in number. Thus, the generic boundaries and higher ranks in the basal clades of fungi are poorly known. Recent DNA based taxonomic studies have provided reliable and accurate information. It is therefore necessary to compile all available information since basal clades genera lack updated checklists or outlines. Recently, Tedersoo et al. (MycoKeys 13:1--20, 2016) accepted Aphelidiomycota and Rozellomycota in Fungal clade. Thus, we regard both these phyla as members in Kingdom Fungi. We accept 16 phyla in basal clades viz. Aphelidiomycota, Basidiobolomycota, Blastocladiomycota, Calcarisporiellomycota, Caulochytriomycota, Chytridiomycota, Entomophthoromycota, Glomeromycota, Kickxellomycota, Monoblepharomycota, Mortierellomycota, Mucoromycota, Neocallimastigomycota, Olpidiomycota, Rozellomycota and Zoopagomycota. Thus, 611 genera in 153 families, 43 orders and 18 classes are provided with details of classification, synonyms, life modes, distribution, recent literature and genomic data. Moreover, Catenariaceae Couch is proposed to be conserved, Cladochytriales Mozl.-Standr. is emended and the family Nephridiophagaceae is introduced
Pain assessment: The role of the radiation therapist
Purpose The focus of this study was to explore the possibility of extending the role of radiation therapists in Ghana to include pain assessment
of the patients they are in daily contact with. The study was carried out at the radiation oncology department of a large teaching hospital
where the circumstances demand the exploration of ways to maximise the effectiveness of the multidisciplinary team in the holistic care of
cancer patients.
Method A case study approach was used to gather text data through interviews (individual and focus group), participant observation and
field notes (radiation therapist and researcher).
Result By extending the role of the radiation therapist to include pain assessment; the quality of care to cancer patients improved, the workload
of the few available radiation oncologists was reduced and patient satisfaction increased.
Conclusion It is recommended that the role of the radiation therapists at the study site is extended to include pain assessment through the
application of a structured protocol
Financial toxicity of cancer care in low- and middle-income countries: a systematic review and meta-analysis.
INTRODUCTION: The costs associated with cancer diagnosis, treatment and care present enormous financial toxicity. However, evidence of financial toxicity associated with cancer in low- and middle-income countries (LMICs) is scarce. AIM: To determine the prevalence, determinants and how financial toxicity has been measured among cancer patients in LMICs. METHODS: Four electronic databases were searched to identify studies of any design that reported financial toxicity among cancer patients in LMICs. Random-effects meta-analysis was used to derive the pooled prevalence of financial toxicity. Sub-group analyses were performed according to costs and determinants of financial toxicity. RESULTS: A total of 31 studies were included in this systematic review and meta-analysis. The pooled prevalence of objective financial toxicity was 56.96% (95% CI, 30.51, 106.32). In sub-group meta-analyses, the objective financial toxicity was higher among cancer patients with household size of more than four (1.17% [95% CI, 1.03, 1.32]; p = 0.02; I2 = 0%), multiple cycles of chemotherapy (1.94% [95% CI, 1.00, 3.75]; p = 0.05; I2 = 43%) and private health facilities (2.87% [95% CI, 1.89, 4.35]; p < 0.00001; I2 = 26%). Included studies hardly focused primarily on subjective measures of financial toxicity, such as material, behavioural and psychosocial. One study reported that 35.4% (n = 152 of 429) of cancer patients experienced high subjective financial toxicity. CONCLUSIONS: This study indicates that cancer diagnosis, treatment and care impose high financial toxicity on cancer patients in LMICs. Further rigorous research on cancer-related financial toxicity is needed
Analysis of Plasmodium falciparum Rh2b deletion polymorphism across different transmission areas
Despite significant progress in controlling malaria, the disease remains a global health burden. The intricate interactions the parasite Plasmodium falciparum has with its host allows it to grow and multiply in human erythrocytes. The mechanism by which P. falciparum merozoites invade human erythrocytes is complex, involving merozoite proteins as well as erythrocyte surface proteins. Members of the P. falciparum reticulocyte binding-like protein homolog (PfRh) family of proteins play a pivotal role in merozoite invasion and hence are important targets of immune responses. Domains within the PfRh2b protein have been implicated in its ability to stimulate natural protective antibodies in patients. More specifically, a 0.58 kbp deletion, at the C-terminus has been reported in high frequencies in Senegalese and Southeast Asian parasite populations, suggesting a possible role in immune evasion. We analysed 1218 P. falciparum clinical isolates, and the results show that this deletion is present in Ghanaian parasite populations (48.5% of all isolates), with Kintampo (hyper-endemic, 53.2%), followed by Accra (Hypo-endemic, 50.3%), Cape Coast (meso-endemic, 47.9%) and Sogakope (meso-endemic, 43.15%). Further analysis of parasite genomes stored in the MalariaGEN database revealed that the deletion variant was common across transmission areas globally, with an overall frequency of about 27.1%. Interestingly, some parasite isolates possessed mixed PfRh2b deletion and full-length alleles. We further showed that levels of antibodies to the domain of PfRh2 protein were similar to antibody levels of PfRh5, indicating it is less recognized by the immune system
