While mental health issues are increasingly gaining attention in Ghana, little is known about the situation among deaf people. This study assessed the mental health care needs of deaf people in Ghana. A descriptive design, consisting of interviews and focus group discussions, was used to collect data from 97 participants. Findings indicated that participants had limited knowledge on mental health issues. Mental health stigma, inaccessible mental health information and exclusion from mental health programmes were the major barriers hindering access to mental health care services. This study bridges the knowledge gap and provides evidence for the implementation of deaf-friendly services.

Background: Benign prostatic hyperplasia (BPH) is defined histologically as adenomyofromatous hyperplasia of the transitional zone of the prostate. It remains the most common benign tumour in men over the age of 50, and transurethral resection of the prostate (TURP) remains the surgical treatment of choice. Objectives: To determine the indications and present our results of transurethral resection of the prostate. Patients and Methods: After obtaining approval from the ethics committee of the private hospital and the university hospital of Bouaké (Côte d’Ivoire), we conducted a cross-sectional study of transurethral resection of the prostate (TURP) to treat benign prostatic hyperplasia (BPH) between January 2021 and April 2023. All patients and their families were informed beforehand and had signed an informed consent form. All patients with benign prostatic hyperplasia (BPH) with ultrasound weight of less than 80 grams were included. The following parameters were studied: age, reason for consultation, ultrasound prostate weight of benign prostatic hyperplasia, indication for TURP, duration of operation, blood loss, duration of post-PRT urinary drainage, length of hospital stay, morbidity and mortality, and outcome. Results: 39 patients with a mean age of 58.3 years (57-77 years) underwent transurethral resection of the prostate (TURP). TURP was indicated in 46.15% (n = 18) of cases of refractory acute urinary retention with failure of the urinary catheter removal test, 17.94% (n = 7) of cases of lower urinary tract disorders that were incapacitating despite treatment, 15.38% (n = 6) of cases of refractory or recurrent urinary tract infection, 10.25% (n = 4) of cases of failure of medical treatment and 10.25% (n = 4) of cases of iterative hematuria. The mean duration of TURP was 53.68 min (48-57), the mean weight of the resected prostate was 58.7 g (35 and 83 g), blood loss was minimal in 92.30% (n = 36), the mean duration of irrigation-washing was 2. 5 days (1-3 da

Background: bladder tumors rank 2nd among urological tumors in sub-Saharan Africa, particularly in Côte d’Ivoire. Objective: to report the results of transurethral resection of the bladder (TURB) for the treatment of non-muscle-infiltrating bladder tumors (NMIBT) in Bouaké. Patients and methods: we conducted a cross-sectional, descriptive study of transurethral resection of the bladder (TURB) for the treatment of non-muscle-infiltrating bladder tumors (NMIBT) between January 2022 and April 2023. All patients and their families were informed in advance and had signed an informed consent form. All patients with a non-muscle-invasive bladder tumor confirmed by an initial TURB were included, and patients with a bladder tumor infiltrating the bladder muscle were excluded. Diagnosis was based on cystoscopy and anatomopathological examination of resection shavings. Parameters studied were: age, sex, risk factors, reason for consultation, clinical signs, cystoscopy findings, stage, grade, Evolution. Results: 17 patients with a mean age of 53.7 years (22-73 years) underwent trans-ureteral bladder resection to treat a non-muscle-infiltrating bladder tumor (NMIBT). Male gender predominated with 88.23% (n = 15), the majority of patients came from the ME region with 47.05% (n = 8), farmers were the most numerous (52.94%;n = 9). The most frequent reason for consultation was macroscopic hematuria with 64.1% (n = 11), risk factors were dominated by urinary bilharziasis with 70.58% (n = 12), physical examination was normal in 47.05% (n = 8). Hemoglobin (HB) levels were between 7.5 and 8.5 g/dl in 52.94% (n = 9). On cystoscopy, the tumor was budding in 76.45% (n = 13), the localization was trigonal in 52.9% (n = 9) and the base of implantation was sessile in 70.52% (n = 12). On ultrasound, the tumor was 3 cm or larger in 70.52% (n = 12). Therapeutically, 82.35% (n = 14) of patients received a blood transfusion. TURB was complete in the majority of cases 88.23% (n = 15).

Background: Leprosy is known to cause disability that leads to severe outcomes like stigma, discrimination, mental health problems and participation restriction. Furthermore, in cases of infectious leprosy, longer delays increase the risk for the spread of the disease. Despite being preventable and curable, a significant proportion of new leprosy patients (39%) in 2019 had grade 2 (Described as Visible disability) at the time of diagnosis signifying late presentation. The aim of this study was to describe patient journeys from first symptoms suggestive of leprosy to a diagnosis and individual and community level factors associated with health seeking behavior of leprosy patients. Methods: This was a cross-sectional explorative study implemented in Kasese, Mayuge and Yumbe districts .A structured questionnaire was used to collect quantitative data. Qualitative assessment included patients, family members, health workers, voluntary health teams and the district health team. Descriptive statistics were presented in terms of percentages, frequency tables, pie Charts and graphs for easy interpretation and discussion. Results: The results indicate that 53% of the respondents identified as female. The median age of the respondents being 34 years, with a range of 1 to 76 years (Mean: 44.7, Mode: 65, Standard-Deviation: 19.6, Kurtosis: 0.6). The most common first symptom noticed by respondents was skin lesions (65%) followed by deformities (18%) (P value = 0.05%) occurring mostly in the feet (P-value = 0.48). Majority (52%) of the patients had taken more than 24 months (SD 18.72 OR 2.75) for a diagnosis to be made with a maximum delay of over 60 months. The most common cause of delay in seeking health care was lack of knowledge on leprosy (P value=Conclusions: There was a delay of 2 years in seeking health care for the majority of the patients. Key barriers to early diagnosis were lack of knowledge and infrastructure. Community sensitization and strengthening capacity buildi

This study evaluated the genetic and agronomic parameter estimates of maize under different nitrogen rates. The trial was established at the Njala Agricultural Research Centre experimental site during 2021 and 2022 in a split block design with three maize varieties (IWCD2, 2009EVDT, and DMR-ESR-yellow) and seven nitrogen (0, 30, 60, 90, 120, 150 and 180 kg∙N∙ha−1) rates. Findings showed that cob diameter and anthesis silking time (ASI) had intermediate heritability, ASI had high genetic advance, ASI and grain yield had high genotypic coefficient of variation (GCV), while traits with high phenotypic coefficient of variation (PCV) were plant height, ASI, grain yield, number of kernel per cob, number of kernel rows, ear length, and ear height. The PCV values were higher than GCV, indicating the influence of the environment in the studied traits. Nitrogen rates and variety significantly (p nd economic parameter estimates increased with increasing nitrogen rates, with the 30 and 180 kg∙N∙ha−1 plots exhibiting the lowest and highest grain yields of 1238 kg∙ha−1 and 2098 kg∙ha−1, respectively. Variety and nitrogen effects on partial factor productivity (PFPN), agronomic efficiency (AEN), net returns (NR), value cost ratio (VCR) and marginal return (MR) indicated that these parameters were significantly affected (p N (41.3 kg grain kg−1∙N) and AEN (29.4 kg grain kg−1∙N) were obtained in the 30 kg∙N∙ha−1 plots, while the highest VCR (2.8) and MR (SLL 1.8 SLL−1 spent on N) were obtained in the 180 kg∙N∙ha−1. The significant influence of variety and nitrogen on traits suggests that increasing yields and maximizing profits require use of appropriate nitrogen fe

中国是非洲的主要投资者，约占非洲大陆外国直接投资(FDI)流量的16%。中国在撒哈拉以南非洲的存在是学术和政治辩论的热点。长期以来，中国始终是该区域的可靠合作伙伴。作为区域成员，加纳和中国拥有历史悠久的双边关系，两国的贸易和投资关系使得彼此受益。但是，作为中国“一带一路”的成员国之一，一些西方国家不断提出质疑，认为中国以投资为陷阱，使得加纳这样的贫穷国家陷入债务危机。　　论文首先展开了文献综述，这包括对流入加纳的FDI的研究文献、中国对加纳投资的背景分析文献。然后阐释了研究方法：定性分析和定量分析。定量分析基于二手资料：IMF、GIPC以及世界银行等的有关文献、期刊和记录资料等。此外，论文也采用了问卷方法，调查了一些政府官员、经济研究专家和一些投资企业。在这些研究的基础上，论文也分析了中国FDI流入加纳面临的挑战和各种条件。研究发现，尽管中国FDI对于加纳经济发展至关重要，但是，也带来了环境和社会问题。　　对中国FDI是否将加纳拖入债务陷阱的探讨，研究证实债务陷阱不可能在加纳发生。加纳的生产、服务、贸易、农业、网络、基础建设等等都受益于来自中国的投资。中国与加纳的关系主要是经济上的，而是否允许中国FDI投资于加纳的公共领域，则完全取决于加纳的政府官员，而不是来自中国的胁迫。　　本文的研究表明，中国在非洲投资并不是西方及其盟国对中国所言的债务陷阱或其他有争议的观点。在此基础上，论文呼吁呼吁进一步加强中国和非洲之间的经济贸易往来。

Severe acute respiratory syndrome coronavirus-2 (SARS CoV-2) has been a global threat spreading in Sierra Leone, and many studies are being conducted using various Statistical models to predict the probable evolution of this pandemic. In this paper, we use the autoregressive integrated moving average (ARIMA) model with the aim of forecasting the cumulative confirmed cases of SARS CoV-2 in Sierra Leone. The Akaike Information Criterion (AIC) was applied to the training data as a criterion method to select the best model. In addition, the statistical measure RMSE and MAPE were utilized for testing this data, and the model with the minimum RMSE and MAPE was selected for future forecasting. ARIMA (3, 2, 1) was confirmed to be the optimal model based on the lowest AIC value. This model was then applied to study the trend of SARS CoV-2 from 1st February 2022 to 30th February 2022. The result shows that incidence of SARS CoV-2 from 1st February 2022 to 30th February 2022, increasing growth steep in Sierra Leone (7718.629, 95% confidence limit of 6785.985 - 8651.274).

Background: Globally, mental health is recognized as one of the major public health issues, and mental health stigma is one of the main barriers to mental healthcare. While several studies have been conducted on the stigma associated with mental health, very little is known about the mental health stigma experienced by deaf persons with mental health conditions in Ghana. This study examines the experiences of double stigmatization by deaf people with mental health conditions in Ghana. Methodology: A descriptive, mixed method data collection was used for seventy-nine (79) participants. The paper presents findings from the only qualitative component of the study. Results: The findings from the study showed that deaf people with mental illness experienced double stigma, namely being stigmatized for being deaf and for having mental illness. This hindered access to mental health services for deaf people with mental health condition. Conclusion: Deaf people with mental health conditions experience double stigmatization which discourages them from seeking professional psychiatric care. This implies that efforts to reduce mental health stigma and create awareness on deafness should be improved upon. It is recommended that, in view of the impact of stigma on the provision and use of mental health care services, strategies to improve access to mental health care, should seriously consider concerns about stigma.
