There has been a growing interest over the past few years in the impact of male nutrition on fertility. Infertility has been linked to male overweight or obesity, and conventional semen parameter values seem to be altered in case of high body mass index （BMI）. A few studies assessing the impact of BMI on sperm DNA integrity have been published, but they did not lead to a strong consensus. Our objective was to explore further the relationship between sperm DNA integrity and BMI, through a 3-year multicentre study. Three hundred and thirty male partners in subfertile couples were included. Using the terminal uridine nick-end labelling （TUNEL） assay, we observed an increased rate of sDerm DNA damage in obese men （odds ratio （95% confidence interval）： 2.5 （1.2-5.1））.

Science Bulletin 2024年第19期69卷 2959-2960页

作者： patrice Simon Université Toulouse Ⅲ Paul Sabatier Laboratoire CIRIMAT (UMR CNRS 5085)

High volumetric energy density energy storage devices are needed for many applications ranging from miniaturized electronics to electric vehicles[1,2].Two-dimensional (2D) nanosheets,such as graphene,MoS2,and MXene are great candidates for assembling compact sheets[1–5],as their horizontal stacking can achieve interlayer distances close to the diameter of electrolyte ions[1,6].The electrolyte ions confined between interlayers of those materials significantly improve the pore and porous volume utilization,thus achieving compact energy storage realized by ion desolvation[1].

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).

Open Journal of Urology 2024年第2期14卷 27-38页

作者： Kouassi patrice Avion N’diamoi Akassimadou Venance Alloka Sadia Kamara Koffi Dje Urology Department Bouaké University Hospital Bouaké C&#244te d’Ivoire

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

Accumulation of Heavy Metals in Maga-Pouss Rice Fields (Far-North Region, Cameroon) and Transfer to Rice Grains

引用

Agricultural Sciences 2024年第3期15卷 311-326页

作者： Diane Madomguia Gilbert Bello Basokdou Kalieu W. Appoline Isabelle patrice Kuitekam Dongo Edouard Nya Serge Hubert Zebaze Togouet Department of Hydraulics and Water Management National Advanced School of Engineering University of Maroua Maroua Cameroon Research Center of Global Studies with Multidisciplinary Units (CREGUM) Maroua Cameroon National Laboratory of Analysis of Agricultural Inputs and Products Ministry of Agriculture and Rural Development Messa-Yaoundé Cameroon Department of Animal Physiology and Biology Faculty of Sciences University of Yaoundé I Yaoundé Cameroon

Monitoring of heavy metals contamination of agricultural products and their transfer and bioaccumulation in crops like rice has become a hot topic worldwide over the last two decades. The present study was carried out to determine the accumulation of heavy metals in rice fields and their transfer to rice grains. Soil, irrigation water and rice grains samples were gathered in Maga-Pouss, Far-North, Cameroon. Concentrations of six heavy metals (lead, cadmium, zinc, copper, iron and mercury) were evaluated by Atomic Absorption Spectrophotometer (AAS). Mercury was not detected in this study. Average concentrations of metals were in this order (in mg/kg): Fe (188.60 ± 97.06) > Pb (63.63 ± 7.11) > Cd (2.59 ± 0.29) > Zn (1.10 ± 1.05) > Cu (0.80 ± 0.73) in water and Pb (105.50 ± 31.11) > Fe (105.50 ± 31.11) > Cu (45.93 ± 14.39) > Zn (22.52 ± 6.40) > Cd (3.15 ± 0.49) in soil. Water in Maga-Pouss rice fields appears to be more harmful than the soil, notably for lead, cadmium and copper. In rice grains, heavy metals were found in this order (mg/kg): Fe (188.01 ± 82.62) > Cu (27.20 ± 0.00) > Zn (23.61 ± 12.42) > Pb (19.50 ± 19.91) > Cd (2.02 ± 1.05). The mean bioconcentration factor (BCF) of metals from soil to rice grains was in the following order: Fe (2.60) > Zn (1.05) > Cd (0.64) > Cu (0.59) > Pb (0.18). From water to rice grains, the order is: Cu (37.26) > Zn (22.49) > Cd (6.97) > Pb (2.74) > Fe (1.94). Rice field pH and electrical conductivity favored the uptake of lead, copper and cadmium by rice grains. The findings of this study will be good documentation for risk assessment, and decision-making by environmental managers in this region.

Background: Maxillofacial trauma affects young adults more. The injury assessment is difficult to establish in low-income countries because of the imaging means, particularly the scanner, which is poorly available and less financially accessible. The aim of this study is to describe the epidemiological profile and the various tomodensitometric aspects of traumatic lesions of the face in patients received in the Radiology department of Kira Hospital. Patients and methods: This is a descriptive retrospective study involving 104 patients of all ages over a period of 2 years from December 2018 to November 2019 in the medical imaging department of KIRA HOSPITAL. We included in our study any patient having undergone a CT scan of the head and presenting at least one lesion of the facial mass, whether associated with other cranioencephalic lesions. Results: Among the 384 patients received for head trauma, 104 patients (27.1% of cases) presented facial damage. The average age of our patients was 32.02 years with extremes of 8 months and 79 years. In our study, 87 of the patients (83.6%) were male. The road accident was the circumstance in which facial trauma occurred in 79 patients (76% of cases). These injuries were accompanied by at least one bone fracture in 97 patients (93.3%). Patients with fractures of more than 3 facial bones accounted for 40.2% of cases and those with fractures of 2 to 3 bones accounted for 44.6% of cases. The midface was the site of the fracture in 85 patients (87.6% of cases). Orbital wall fractures were noted in 57 patients (58.8% of cases) and the jawbone was the site of a fracture in 50 patients (51.5% of cases). In the vault, the fractures involved the extra-facial frontal bone (36.1% of cases) and temporal bone (18.6% of cases). Cerebral contusion was noted in 41.2% of patients and pneumoencephaly in 15.5% of patients. Extradural hematoma was present in 16 patients and subdural hematoma affected 13 patients.

Introduction: Pesticides are currently an essential component of agricultural production techniques for controlling pests and weeds. In Burkina Faso, non-compliance with good practice in the use of pesticides poses a real health problem for the population. This study examines the health risks associated with pesticide management in rice-growing areas. Material and Methods: A field survey was conducted in Bama, involving farmers, focusing on their socio-demographic characteristics, pesticide usage, and health effects. Cholinesterase levels were measured in subsample of farmers using a portable device. Data were analysed using Microsoft Excel, calculating means and percentages for various practices. Health consultations, protection methods, and pesticide management were studied. Erythrocyte acetylcholinesterase activity was compared before and after treatment. Data were categorised into classes based on inhibition levels, and correlation analyses determined relationships between variables such as age, years of experience, and cholinesterase activity. Results: The results indicate that rice cultivation is mainly carried out by a fairly young population, with nearly 63% being under the age of 50. Common poor practices in pesticide use include improper storage and reuse of leftover pesticides. Seven types of pesticides were identified, including organophosphates such as glyphosate, which was used in 26.7% of cases. This organophosphate has resulted in class B poisoning, causing a 30% - 50% reduction in erythrocyte cholinesterase activity. The health effects of pesticide use are felt by agricultural farmers through various symptoms of poisoning. Conclusion: To reduce the occurrence of pesticide poisoning, it is essential to launch information and awareness campaigns among the population and farmers to promote safe practices in pesticide use in Bama, Burkina Faso.
