RESUMEN

The data presented here are from the Offinso North District Farm Health Study (ONFAHS), a population-based cross-sectional study among vegetable farmers in Ghana. The paper addresses knowledge, pesticide handling practices, and protective measures related to pesticide use by self-reported symptoms for 310 adult farmers who completed a comprehensive questionnaire on pesticide management practices and health. In addition, an inventory was prepared using information supplied by pesticide sellers/dealers in this district. We report that cough and wheezing (but not breathlessness) are positively associated with stirring pesticide preparations with bare hands/drinking water while mixing/applying pesticides, and stirring pesticide preparations with bare hands/drinking water/smoking cigarettes while mixing/applying pesticides. There is a significant exposure-response association between the number of precautionary measures practiced while handling pesticides and cough and wheezing but not with breathlessness. We also found unsafe practices to be associated with sexual dysfunction, nervousness, and lack of concentration. The results also suggest a negative association between practice of any precautionary measure when mixing/applying pesticides and sexual dysfunction, nervousness, and lack of concentration. We found that in spite of the fact that farmers have adequate knowledge about the environment and health effects of pesticides, several unhygienic practices are in widespread use, indicating that knowledge is not necessarily always translated in action. Further action is necessary to promote the safe use of pesticides and to replace existing poor management practices among these and other farmers in Ghana.

RESUMEN

BACKGROUND: Indiscriminate use of pesticides is a common practice amongst farmers in Low and Middle Income Countries (LMIC) across the globe. However, there is little evidence defining whether pesticide use is associated with respiratory symptoms. OBJECTIVES: This cross-sectional study was conducted with 300 vegetable farmers in southern Ghana (Akumadan). Data on pesticide use was collected with an interviewed-administered questionnaire. The concentration of seven organochlorine pesticides and 3 pyrethroid pesticides was assayed in urine collected from a sub-population of 100 vegetable farmers by a gas chromatograph equipped with an electron capture detector (GC-ECD). RESULTS: A statistically significant exposure-response relationship of years per day spent mixing/applying fumigant with wheezing [30-60 days/year: prevalence ratio (PR)=1.80 (95% CI 1.30, 2.50); >60days/year: 3.25 (1.70-6.33), p for trend=0.003] and hours per day spent mixing/applying fumigant with wheezing [1-2h/day: 1.20 (1.02-1.41), 3-5h/day: 1.45 (1.05-1.99), >5h/day: 1.74 (1.07-2.81), p for trend=0.0225]; days per year spent mixing/applying fungicide with wheezing [30-60 days/year: 2.04 (1.31-3.17); >60days/year: 4.16 (1.72-10.08), p for trend=0.0017] and h per day spent mixing/applying fungicide with phlegm production [1-2h/day: 1.25 (1.05-1.47), 3-5h/day: 1.55 (1.11-2.17), >5h/day: 1.93 (1.17-3.19), p for trend=0.0028] and with wheezing [1-2h/day: 1.10 (1.00-1.50), 3-5h/day: 1.20 (1.11-1.72), >5h/day: 1.32 (1.09-2.53), p for trend=0.0088]; h per day spent mixing/applying insecticide with phlegm production [1-2h/day: 1.23 (1.09-1.62), 3-5h/day: 1.51 (1.20-2.58), >5h/day: 1.85 (1.31-4.15), p for trend=0.0387] and wheezing [1-2h/day: 1.22 (1.02-1.46), 3-5h/day: 1.49 (1.04-2.12), >5h/day: 1.81 (1.07-3.08), p for trend=0.0185] were observed. Statistically significant exposure-response association was also observed for a combination of activities that exposes farmers to pesticide with all 3 respiratory symptoms. Furthermore, significant exposure-response associations for 3 organochlorine insecticides: beta-HCH, heptachlor and endosulfan sulfate were noted. CONCLUSIONS: In conclusion, vegetable farmers in Ghana may be at increased risk for respiratory symptoms as a result of exposure to pesticides.

RESUMEN

In recent times, surface water resource in the Western Region of Ghana has been found to be inadequate in supply and polluted by various anthropogenic activities. As a result of these problems, the demand for groundwater by the human populations in the peri-urban communities for domestic, municipal and irrigation purposes has increased without prior knowledge of its water quality. Water samples were collected from 14 public hand-dug wells during the rainy season in 2013 and investigated for total coliforms, Escherichia coli, mercury (Hg), arsenic (As), cadmium (Cd) and physicochemical parameters. Multivariate statistical analysis of the dataset and a linear stoichiometric plot of major ions were applied to group the water samples and to identify the main factors and sources of contamination. Hierarchal cluster analysis revealed four clusters from the hydrochemical variables (R-mode) and three clusters in the case of water samples (Q-mode) after z score standardization. Principal component analysis after a varimax rotation of the dataset indicated that the four factors extracted explained 93.3 % of the total variance, which highlighted salinity, toxic elements and hardness pollution as the dominant factors affecting groundwater quality. Cation exchange, mineral dissolution and silicate weathering influenced groundwater quality. The ranking order of major ions was Na(+) > Ca(2+) > K(+) > Mg(2+) and Cl(-) > SO4 (2-) > HCO3 (-). Based on piper plot and the hydrogeology of the study area, sodium chloride (86 %), sodium hydrogen carbonate and sodium carbonate (14 %) water types were identified. Although E. coli were absent in the water samples, 36 % of the wells contained total coliforms (Enterobacter species) which exceeded the WHO guidelines limit of zero colony-forming unit (CFU)/100 mL of drinking water. With the exception of Hg, the concentration of As and Cd in 79 and 43 % of the water samples exceeded the WHO guideline limits of 10 and 3 µg/L for drinking water, respectively. Reported values in some areas in Nigeria, Malaysia and USA indicated that the maximum concentration of Cd was low and As was high in this study. Health risk assessment of Cd, As and Hg based on average daily dose, hazard quotient and cancer risk was determined. In conclusion, multiple natural processes and anthropogenic activities from non-point sources contributed significantly to groundwater salinization, hardness, toxic element and microbiological contamination of the study area. The outcome of this study can be used as a baseline data to prioritize areas for future sustainable development of public wells.

RESUMEN

Prostate cancer is the second most frequently diagnosed cancer among men worldwide, and it represents a substantial worldwide health issue, primarily impacting men as they grow older. Understanding its epidemiology and etiology is crucial for crafting efficient preventive measures and enhancing treatment results. The epidemiology of this disease provides valuable insights into its prevalence and distribution. Age is a critical factor, with the risk of prostate cancer increasing with advancing years. Incidence rates are notably higher in developed countries, suggesting a role for lifestyle and environmental factors. Furthermore, there are significant racial and geographical disparities in prostate cancer incidence, with African-American men experiencing both a higher incidence and more aggressive forms of the disease. On the other hand, hormones, especially testosterone and its conversion to dihydrotestosterone (DHT), contribute to prostate cell growth and, potentially, cancer. Genetics also plays a pivotal role, with certain gene mutations, like Breast Cancer gene 1 & 2 (BRCA1 and BRCA2), elevating risk. Dietary habits and lifestyle choices influence susceptibility, with diets low in fruits and vegetables and high in saturated fats linked to higher risk. Chronic inflammation, often tied to prostatitis, may further increase susceptibility to prostate cancer. This review article explores the complex realm of prostate cancer, providing insights into its occurrence, factors that elevate risks, and the fundamental factors that play a role in its emergence and how we can prevent it.

RESUMEN

Introduction YouTube, the world's largest video platform, hosts thousands of educational surgical videos that many trainees rely on to enhance their understanding and proficiency in various surgical procedures. Consequently, a crucial inquiry arises regarding the trustworthiness of these videos as a valuable resource for these trainees. In this article, we address this question by focusing on one of the most frequently performed surgical procedures in the field of urology and assessing the effectiveness of these videos as an educational tool for urology trainees (ST3+: Specialty Training Year 3 and above). Methodology We conducted a comprehensive search on YouTube for all videos related to 'Testicular Exploration'. After applying specific inclusion and exclusion criteria, we identified a total of nine eligible videos for analysis. These videos were assessed using the LAParoscopic Surgery Video Educational GuidelineS (LAP-VEGaS) scoring system, which categorized them into two distinct groups. The first group, known as the 'high-quality group', included videos that scored 11 points or higher according to the LAP-VEGaS scoring criteria. The second group, termed the 'low-quality group', consisted of videos that scored less than 11 points using the LAP-VEGaS scoring tool. Additionally, we collected data on various metrics, such as video view counts, duration, likes and dislikes counts, comments count, like ratio, view ratio, and power index, and performed a comparative analysis between the two aforementioned groups. Results  Between April 2013 and September 2023, the selected videos exhibited an average total view count of 95,546±138,000. The videos had an average duration of 6.35±2.26 minutes. Furthermore, the mean values for both likes and dislikes were 461.55±581 and 2.89±2.86, respectively. In contrast, the mean like ratio, view ratio, and power index were 0.98±0.0112, 176,00±13,100, and 173.80±131, respectively. The mean LAP-VEGaS scores for videos related to testicular exploration were 9.94±2.05. It is noteworthy that the first group had a statistically higher number of dislikes; however, the view count, comments count, likes count, and view ratio were statistically lower in the same group. Conclusion Videos related to testicular exploration on YouTube exhibit notably low quality and do not serve as a valuable resource for urology trainees. Key factors such as video duration, total view count, and viewer interactions (including likes, dislikes, and comments) should not be relied upon as indicators of educational video quality. Consequently, it is advisable for urology trainees to refrain from using YouTube as a primary source for learning about testicular exploration. Instead, they should seek guidance and support from experienced senior colleagues, educational supervisors, or consultants to explore more reliable sources of information for this surgical procedure.

RESUMEN

The objectives of this present study were to assess the level of organochlorine pesticide (OCP) residues in fruits and to determine the potential health risks associated with the exposure to these pesticides. A total of 120 fruits (watermelon, pineapple, and banana) were collected from five communities and a local market within the Mampong Municipality and analyzed for organochlorine pesticide residues. The results showed that the concentrations ranged from not detectable (ND)-48.22 ng/g for DDTs, ND-19.03 ng/g for HCHs, ND-4.10 ng/g for CHLs, ND-22.84 ng/g for Aldrin, and ND-11.53 ng/g for other OCPs. Levels of methoxychlor, Aldrin and gamma-hexachlorocyclohexane (HCH) exceeded the maximum residue limits in watermelon. Estimated health risk revealed that Aldrin in watermelon could pose potential toxicity to the consumer. Estimated average daily intake for Aldrin was above the acceptable average daily intake.

RESUMEN

An effective method for determination of indicator polychlorinated biphenyls (PCBs) has been validated using gas chromatography (GC) equipped with electron capture detector (ECD). The GC-ECD method was validated by determining the linear range (working range) for determination of the compounds, minimum detectable quantities (MDQ), the precision and accuracy of the method for the analysis of the compounds. MDQ obtained for the compounds ranges from 0.0005 to 0.002 ng. Indeed the method was found to be more sensitive as the number of chlorine atoms attached to the biphenyl increases. The precision and accuracy of the GC method validated ranges from 2.4% to 14.5% and -7.0% to 14.6% respectively. Coefficient of variation associated with the repeatability of the retention times and corresponding peak areas was found to be 0.0001-0.0007 for the retention times and 0.0014-0.059 for the peak areas. Percentage recoveries for the compounds were in the range of 95.7-101.0%. The validated method was then applied to determine levels of indicator PCBs in sediments sampled from eleven sampling points along the Lake Bosuntwi in Ghana and the highest PCB load of 19.17 ng g(-1) was recorded at Pipie No. 2. PCB 52 and PCB 101 were found to be the most ubiquitous indicator PCBs in the study area, both with 90.91% occurrence.
