Épuisement des réserves et conflits fonciers inter-collectivités dans l’ouest de la région des savanes au nord-togo

L’émergence des territoires et l’épuisement des saltus stimulent des questions foncières longtemps restées en veilleuse. Au T ogo en général et spécifiquement dans l’Ouest de la Région des Savanes, la terre est une propriété privée des lignages. Le droit foncier y repose sur la prééminence du droit du premier occupant et matérialisé par une divinité appelée Tingban. L’insuffisance des preuves de prééminence et l’authenticité des fétiches, source de droit, opposent souvent les collectivités. La présente étude décrit l’épuisement des ressources foncières et analyse les conflits fonciers qui opposent les collectivités dans l’Ouest de la Région des Savanes. La méthodologie adoptée repose sur l’observation participante, la recherche documentaire et les entretiens. Les résultats révèlent de nombreuses disputes socio-foncières qui opposent les lignages, les villages et les cantons. Les collectivités contestent entre elles, les droits de paternité sur les terres dans 74% des cas alors que 26% des querelles foncières sont dus aux remises en cause des limites des propriétés collectives. Ces contestations plongent leurs racines dans la complexité du droit foncier coutumier fondé sur la prééminence du droit du premier occupant. Elles sont aussi liées à la non maîtrise des limites des domaines fonciers lignagers et des territoires cantonaux respectivement par les descendants, les chefs de villages et les chefs de cantons.

Spinal brucellosis without apparent risk factors: a case-based diagnostic approach and literature review

Brucellosis is a zoonotic infection often linked to direct or indirect exposure to animals or unpasteurized dairy products. Atypical presentations in patients without classical risk factors pose significant diagnostic and management challenges. A 68-year-old woman presented with a 2-month history of burning pain involving cervical and lumbar regions, associated with weight loss, decreased appetite, and subjective fever. Examination revealed paravertebral tenderness and left knee swelling with effusion. Previous MRI showed multifocal marrow edema and soft tissue thickening in the lumbar spine, suggesting infection or inflammation. The patient denies exposure to unpasteurized dairy products, raw meat, or animals. Brucella serology revealed positive IgG with Brucella melitensis titer 1:160, later confirmed by blood cultures. PET imaging demonstrated multifocal metabolically active arthritic changes involving the spine, shoulders, and knees. Arthrocentesis confirmed inflammatory arthritis due to brucellosis. The patient was started on doxycycline, rifampin, and a 14-day course of intravenous gentamicin. During hospitalization, management was complicated by persistent knee pain and swelling requiring multimodal analgesia. Spinal brucellosis in the absence of classical risk factors is an odd presentation, emphasizing the importance of maintaining a high index of suspicion in endemic regions. Advanced imaging and microbiological confirmation are pivotal procedures in diagnosis. Early recognition of atypical brucellosis is critical to prevent complications and improve outcomes.

A study to assess the effectiveness of aerobic training on exercise tolerance and functional independence in patients with multiple sclerosis – a quasi experimental study

Multiple Sclerosis (MS) is a chronic neurological condition characterized by an interruption of action potentials in the brain and spinal cord due to areas of inflammation, demyelination and axonal degeneration. Most people with Multiple Sclerosis (PWMS) complain of physical activity limitations due to fatigue and reduced Exercise Tolerance that leads to reduction in Functional Independence. Till date, there is a limited published evidence of the efficacy of aerobic training on Exercise Tolerance and Functional Independence in individuals with Multiple Sclerosis, although some studies that incorporate aerobic training into rehabilitation programs report positive outcomes with no harmful effects. This was an effort to study the effect of aerobic training on exercise tolerance and functional independence in patients with Multiple Sclerosis. 12 Subjects were selected for the study on the basis of convenient Sampling method. Subjects who were independently mobile with Kurtzke Expanded Disability Status Scale (EDSS) score between 2 and 6.5 and medically stable were included for the study. The parameters of Exercise Tolerance and Functional Independence were assessed with six min walk test distance (6MWTD) and FIMTM+FAM respectively as Pre test measurement. All the subjects were given Aerobic training(AT) with Elliptical trainer and the intensity of the exercise was individualized according to their tolerance with initial stage incline of 0 (no incline) and a resistance of 1 (lowest possible resistance) was fixed. Training was done in a well ventilated training setup and subject was provided with cool water to minimize the effect of heat on activity. Subjects were monitored during the exercise training via heart rate monitor fixed to the machine; heart rate was taken every 3 minutes. The subjects were advised to perform the exercise in their own pace throughout training session for 30 min with breaks as many as they require. Progression of exercise intensity was achieved by increasing the resistance level of the Elliptical machine and/or by increasing the subject's steps per minute (stepping speed was controlled by the subject and not the elliptical machine).To ensure the progress of exercise protocol, the exercise intensity increased every 3 to 4 sessions. Totally 15 sessions were given in 6 weeks period. After 15 session of training Post test measurement for Exercise Tolerance and Functional Independence were taken. The Significance of the Pre test Post test difference were analyzed statistically using student paired “t‟ test . After 6 weeks (15 sessions) of Aerobic training with Elliptical trainer the subjects improved in Exercise Tolerance and level of Functional Independence as compared with the base line conditions. This was indicated by the changes in the Distance covered in 6 MWT and the FIMTM+ FAM score with P value <0.001. In all the subjects who were participated in this study showed greater improvement in the 6 Minute walk test distance and FIMTM+FAM scores. It implies that Aerobic training by Elliptical Trainer is effective for improving Exercise Tolerance and Functional Independence in PWMS.

Knowledge and attitudes towards stroke in semi-urban communities in north central nigeria

Stroke and its associated disabilities are a growing public health challenge in many developing countries where a combination of poor awareness and poor medical care is driving up mortality rates. The rising cases are attributed to the rising prevalence of uncontrolled hypertension, obesity, smoking, alcohol abuse, and diabetes mellitus within the population. The prevention of stroke through awareness, knowledge, and lifestyle modification is a common approach used in public health intervention programs. Awareness and knowledge of stroke vary widely between communities partly because of access to relevant health information. This study assessed awareness, knowledge of stroke risk factors, and attitude toward stroke prevention. This study was a community-based survey among adults ≥40 years old in semi-urban communities of two local government area councils of Benue State, North Central Nigeria. The sixteen-item questionnaire used in this study is subdivided into socio-demographic information, knowledge of risk factors, symptoms of stroke, current morbidity, and attitude toward stroke prevention. The survey was done using two adults per household selected using simple random method and completed questionnaires were retrieved for analysis. The Chi-square test was used to determine the association between demographic variables and knowledge of stroke. The result showed poor levels of stroke awareness (47.3%), knowledge (44.6%), symptoms (44.6%), risk factors (20.6%), and symptoms (44.6%). Awareness of stroke and its risk factors is significantly association with age, gender, marital status, educational status, occupation, and income. Many respondents had poor knowledge of stroke and its risk factors. There is a need for improvement in stroke awareness in underserved communities, particularly those with limited access to mass media.

Review on the cardioprotective role of pinocemrin in atherosclerosis, myocardial infarction and related vascular-myocardial remodeling

Cardiovascular diseases represent a formidable global health challenge, standing as the foremost cause of both mortality and morbidity. Atherosclerosis and myocardial infarction, as primary contributors to this epidemiological burden, underscore the urgent need for effective therapeutic interventions with minimal side effects. Natural compounds derived from plants have emerged as promising candidates, given their enhanced efficacy and reduced adverse effects. Phytochemicals, in particular, have garnered attention for their potential as alternative therapeutic agents. This review delves into the cardioprotective potential of pinocembrin (5,7-Dihydroxy flavanone), a compound extracted from various plants and honey. Renowned for its antioxidant and anti-inflammatory properties, pinocembrin demonstrates significant cardioprotective effects through the modulation of diverse signaling pathways. Atherosclerosis and myocardial infarction entail intricate cellular mechanisms involving oxidative stress, inflammatory responses, cellular remodeling, and programmed cell death. Pinocembrin, by targeting key factors within these pathways, exhibits cardioprotective actions. While existing research underscores its effectiveness, further investigations are warranted to elucidate the impact of pinocembrin on additional cardiovascular conditions and explore novel molecular targets, thus paving the way for future advancements in therapeutic interventions.

Deep learning-based detection system for heavy-construction vehicles and urban traffic monitoring

In this intelligent transportation systems era, traffic congestion analysis in terms of vehicle detection followed by tracking their speed is gaining tremendous attention due to its complicated intrinsic ingredients. Specifically, in the existing literature, vehicle detection on highway roads are studied extensively while, to the best of our knowledge the identification and tracking of heavy-construction vehicles such as rollers are not yet fully explored. More specifically, heavy- construction vehicles such as road rollers, trenchers and bulldozers significantly aggravate the congestion in urban roads during peak hours because of their deadly slow movement rates accompanied by their occupation of majority of road portions. Due to these reasons, promising frameworks are very much important, which can identify the heavy-construction vehicles moving in urban traffic-prone roads so that appropriate congestion evaluation strategies can be adopted to monitor traffic situations. To solve these issues, this article proposes a new deep-learning based detection framework, which employs Single Shot Detector (SSD)-based object detection system consisting of CNNs. The experimental evaluations extensively carried out on three different datasets including the benchmark ones MIO-TCD localization dataset, clearly demonstrate the enhanced performance of the proposed detection framework in terms of confidence scores and time efficiency when compared to the existing techniques.

Public perception and behavior on the disposal of unused and expired drugs

Evidence demonstrates that inappropriate drug disposal creates a significant risk to global environmental safety. Study participants' knowledge, attitude and practice regarding the disposal of unwanted and expired medications were assessed. The study was carried out at Sebha city, in southwestern Libya, from October 2021 to April 2022. A self-administered questionnaire designed explicitly to be completed by a respondent without an interviewer's assistance was used. Out of 650, only 500 completed questionnaires was returned. The majority of the respondents admitted they have at least one medication stored at home (71.6%). Keeping expired drugs were reported by 28.2% of the respondents compared with unused medications in their house (51.2%). Almost half of the respondents (47.4%) declared that their medication were taking from the private pharmacies. “I’ll need it in the future” (48.8%), "Medicines change" (37.2%) and "Symptoms improve and recover" (32.6%) were the top three explanations given by participants. The majority of drugs reported were antibiotics (41.0%). This is followed by antipyretic and analgesic drugs, which were used by 29.8% and 27.8% of respondents, respectively. 52.2% of the respondents agreed that disposing of medicines in the garbage is the most appropriate method. Concordantly, the majority of them indicated they discarded unused or expired medicines whether they were solid (82.6%), liquid (58.4%), or semisolid (79.6%). The majority of participants indicated they were aware of the negative impact of drug waste on the environment (80.6%). More than three quarters of the participants said they had never been given instructions on how to properly dispose of medications and 60.8% thought a medical team would be the best source of knowledge. Despite acknowledging being aware of the harmful effects on the environment, the majority of participants admitted to keeping unneeded pharmaceuticals in their homes and throwing them out in the trash. The government should support the pharmacists' role in educating the public about how to properly dispose of their medications and establish the Return Unwanted Medicines Project in order to raise awareness and create cost-effective medication waste management programs.

N-gram-based machine learning approach for bot or human detection from text messages

Social bots are computer programs created for automating general human activities like the generation of messages. The rise of bots in social network platforms has led to malicious activities such as content pollution like spammers or malware dissemination of misinformation. Most of the researchers focused on detecting bot accounts in social media platforms to avoid the damages done to the opinions of users. In this work, n-gram based approach is proposed for a bot or human detection. The content-based features of character n-grams and word n-grams are used. The character and word n-grams are successfully proved in various authorship analysis tasks to improve accuracy. A huge number of n-grams is identified after applying different pre-processing techniques. The high dimensionality of features is reduced by using a feature selection technique of the Relevant Discrimination Criterion. The text is represented as vectors by using a reduced set of features. Different term weight measures are used in the experiment to compute the weight of n-grams features in the document vector representation. Two classification algorithms, Support Vector Machine, and Random Forest are used to train the model using document vectors. The proposed approach was applied to the dataset provided in PAN 2019 competition bot detection task. The Random Forest classifier obtained the best accuracy of 0.9456 for bot/human detection.

Efficacy of vilanterol-fluticasone furoate versus formoterol-budesonide combination therapy in stable asthma

The present study evaluates the efficacy of Vilanterol-Fluticasone Furoate (VI-FF) versus Formoterol-Budesonide (FM-BD) combination therapy in stable asthma. Both regimens led to significant improvements in asthma control, as evidenced by marked increases in FEV1 (% predicted) and ACT scores over time. The demographic characteristics, baseline respiratory symptoms, and treatment outcomes were similar between the groups, indicating that both strategies were equally effective for managing asthma. The findings indicate that both VI-FF once daily and FM-BD twice daily therapies enhance lung function and asthma control. Significant improvements in FEV1 (% predicted) and ACT scores were observed in both groups, as confirmed by intention-to-treat (ITT) and perprotocol (PPA) analyses. The equivalent efficacy of VI-FF and FM-BD, combined with the convenience of once-daily dosing, suggests that VI-FF may be preferable for patients who struggle with a twice-daily regimen. These findings highlight VI-FF as a convenient and reliable treatment, particularly can benefit patients with adherence challenges. In conclusion, our study's findings align well with other studies regarding demographic characteristics, baseline symptoms, exacerbation history, hospitalization history, and spirometry results. This consistency reinforces the validity and reliability of our results, suggesting that both VI-FF and FM-BD are effective options for stable asthma. The comparable efficacy supports flexibility in treatment choices, allowing for personalized asthma management. Future research should explore the long-term benefits and adherence patterns associated with these treatments to further optimize asthma management.
