Uric acid-lowering effects of sodium-glucose cotransporter 2 inhibitors for preventing cardiovascular events and mortality: A systematic review and meta-analysis.

BACKGROUND: To evaluate the effect of a 1 mg/dl reduction in uric acid (UA) on cardiovascular events and mortality in patients treated with sodium-glucose cotransporter 2 (SGLT2) inhibitors. RESEARCH DESIGN AND METHODS: We performed a systematic review of the MEDLINE and EMBASE databases searched up to 30 June 2023 (PROSPERO, CRD42022355479) to identify large-scale SGLT2 inhibitor trials. Random-effects meta-analyses were used to pool the estimates. RESULTS: In total, five SGLT2 inhibitor trials (31 535 patients, 54% with heart failure) were analysed. Over a median follow-up of 2.2 years, the mean reduction in UA was -0.79 mg/dl (95% confidence interval (CI), -1.03 to -0.54). Every 1 mg/dl reduction in UA was associated with a significantly lower risk of a composite of cardiovascular death and hospitalization for heart failure [hazard ratio, 0.64 (95% CI, 0.46-0.88)] and hospitalization for heart failure (0.68; 95% CI, 0.62-0.74), with a similar risk of mortality. CONCLUSIONS: SGLT2 inhibitors reduced UA levels and cardiovascular events independently of heart failure status.

Multidisciplinary estimates of connectivity and population structure suggest the use of multiple units for the conservation and management of meagre, Argyrosomus regius.

Information on population structure and connectivity of targeted species is key for proper implementation of spatial conservation measures. We used a combination of genomics, biophysical modelling, and biotelemetry to infer the population structure and connectivity of Atlantic meagre, an important fisheries resource throughout its distribution. Genetic samples from previously identified Atlantic spawning locations (Gironde, Tejo, Guadalquivir, Banc d'Arguin) and two additional regions (Algarve and Senegal) were analysed using genome-wide SNP-genotyping and mitochondrial DNA analyses. Biophysical models were conducted to investigate larval dispersal and connectivity from the known Atlantic spawning locations. Additionally, thirteen fish were double-tagged with biotelemetry transmitters off the Algarve (Portugal) to assess movement patterns and connectivity of adult individuals. This multidisciplinary approach provided a robust overview of meagre population structure and connectivity in the Atlantic. Nuclear SNP-genotyping showed a clear differentiation between the European and African populations, with significant isolation of the few known Atlantic spawning sites. The limited level of connectivity between these subpopulations is potentially driven by adults, capable of wide-ranging movements and connecting sites 500 km apart, as evidenced by tagging studies, whilst larval dispersal inferred by modelling is much more limited (average of 52 km; 95% of connectivity events up to 174 km). Our results show sufficient evidence of population structure, particularly between Africa and Europe but also within Europe, for the meagre to be managed as separate stocks. Additionally, considering the low degree of larvae connectivity, the implementation of marine protected areas in key spawning sites could be crucial towards species sustainability.

Ischemic strokes revealing neurosyphilis: Study of six (6) observations at the neurology Department of the University Hospital of Conakry.

Introduction: In sub-Saharan Africa (SSA), stroke is a major public health problem and the etiological aspects are poorly studied and documented because of under-medicalization; the syphilitic etiology is rarely mentioned. Patients and methods: We performed a retrospective study of 472 patients hospitalized for ischemic stroke between 2016 and 2021 in the Neurology Department of the University Hospital of Conakry, confirmed by neuroradiological explorations (brain CT, MRI-Angio) and a biological workup including VDRL-TPHA serological reactions in blood and CSF. Results: Syphilitic etiology was retained for six (6) patients (4 men and 2 women) with a mean age of 43 years (extremes 36 and 49 years). The clinical picture was dominated by carotid syndromes: superficial and deep sylvian syndrome, anterior cerebral artery syndrome and vertebro-basilar syndromes and one case of lacunar syndrome.The diagnosis was based on the positivity of serological reactions (VDRL-TPHA) in blood and cerebrospinal fluid (CSF) and the presence of a predominantly lymphocytic hypercellularity and a hyperproteinorachy in the CSF in the absence of any other etiology. Conclusion: These neurological vascular syndromes consecutive to a cerebral treponematous attack are often the result of a still poorly conducted management of primary and secondary syphilis in our country.

[Gunshot wounds of low urinary tract in period of security crisis at the Sominé Dolo Hospital of Mopti (Mali): Epidemiological and diagnostic aspects]. / Blessures par arme à feu du bas appareil urinaire en période de crise sécuritaire à l'hôpital Sominé Dolo de Mopti (Mali) : aspects épidémiologiques et diagnostiques.

INTRODUCTION: Firearm injuries to the lower urinary tract are injuries resulting from an energy transfer from a projectile fired by a firearm or a blast from a firearm, to the bladder, prostate, urethra and terminal ureter. Our objective was to describe the epidemiological and diagnostic aspects in the context of a security crisis. PATIENTS AND METHOD: This was a descriptive cross-sectional study of lower urinary tract firearm injuries at Sominé Dolo Hospital in Mopti from January 2017 to December 2021. RESULTS: In five years, 29 traumas of the lower urinary tract have been collected, about 6 cases per year. The mean age of patients was 27.48 years, the sex ratio was 13.5/1. The main circumstances of occurrence were intercommunal violence 51.72 %, war wounds 31.03 %. Injuries were inflicted by rifles in 62.1 % and improvised explosive devices in 37.9 %. The main modes of discovery were acute urine retention, hematuria and penoscrotal wounds respectively in 31.03 %, 20.69 %, 17.24 %. The organs affected were the urethra in 58.62 %, the bladder, 37.93 %, the prostate 3.45 %. Associated non-urological lesions present in 68.96 % (n=20) were dominated by intestinal lesions and pelvic fractures. CONCLUSION: Firearm injuries to the lower urinary tract are rare despite the context of the security crisis. They affect young men, are mostly linked to intercommunal violence, and are dominated by urethral and bladder injuries.

EPILEPTIC SEIZURES REVEALING STURGE WEBER'S DISEASE IN A TROPICAL ENVIRONMENT: STUDY OF EIGHT CASES.

In sub-Saharan Africa (SSA), the etiological factors of epilepsy are multiple and phacomatoses, in particular Sturge weber's disease, are rarely reported due to under-medicalization and insufficient multidisciplinary care. We carried out a retrospective study of 216 patients hospitalized for recurrent epileptic seizures between 2015 and 2022 in the neurology and pediatrics department of the University Hospital Center of Conakry, among whom eight (8) patients were identified for Sturge Weber's disease in order to reassess this pathology from a clinical and paraclinical point of view in a tropical environment. Sturge Weber's disease was retained in eight (8) on the presence of symptomatic partial epileptic seizures (age 6 months to 14 years) with frequency of status epilepticus, homonymous lateral hemiparesis linked to occipital involvement, piriform calcifications on imaging and ocular disorders. The delay in consultation and medical care revealed severe mental deterioration in our patients. This study shows a stereotyped clinical picture in a context of aggravation of signs related to a delay in multidisciplinary management. These results are important for the diagnostic, therapeutic and prognostic discussion.

GAYET WERNICKE'S ENCEPHALOPATHY AFTER COVID-19 IN ELDERLY SUBJECTS IN TROPICAL ENVIRONMENTS: STUDY OF SIX (6) OBSERVATIONS IN CONAKRY.

In sub-Saharan Africa, the COVID-19 pandemic has caused severe malnutrition in elderly populations with the appearance of vitamin deficiencies, in particular thiamine responsible for Gayet Wernicke's encephalopathy (EGW). We present a series of six (6) patients hospitalized in the Neurology Department of the CHU Ignace Deen for the management of a brain syndrome with vigilance disorders after recovery from COVID-19, including oculomotor disorders, motor incoordination on a course of severe weight loss. The six patients underwent an evaluation of malnutrition by determining the WHO body mass index, the Detsky index, the serum albumin assay, the thiamine assay and a neuroradiological assessment (MRI) and an electroencephalogram (EEG) examination although this does not seem necessary for diagnosis. Study of nutritional status: weight loss greater than 5%, patients in Desky group B and C, plasma albumin<30 g/l, lowered thiamine and MRI neuroradiological data: by the existence of hypersignals in certain regions of the neocortex, certain gray nuclei, the mammillary bodies the thalamic nuclei close to the wall of the 3rd ventricle and the regions bordering the 4th ventricle sign Gayet Wernicke's encephalopathy syndrome. This study shows a stereotyped clinical, biological, neuroradiological and evolutionary profile of Gayet Wernicke's encephalopathy in elderly subjects recovered from Covid-19 with proven malnutrition. These results are useful for the therapeutic and prognostic discussion.

Spinal metastases of bronchopulmonary cancer: Role of spinal surgery and value of prognostic scores (Modified Tokuhashi and Tomita).

INTRODUCTION: Bone metastasis is frequent in bronchopulmonary cancer. We report a series of 52 patients, and analyze indications and the efficacy of surgery. MATERIALS AND METHODS: We retrospectively studied the records of 52 patients operated on for spinal metastases of bronchopulmonary cancer over a 6-year period from January 2009 to December 2014 in the neurosurgery department of the North Hospital of Marseille, France. RESULTS: Mean age was 63.6years; with a sex ratio of 3:1 (M:F). Spinal pain associated with vertebral fracture and spinal cord compression was the most frequent clinical presentation (59.6%). SINS score was≥7 in 78.9% of cases. Karnofski Performance Status was average in 67.4% of cases. Predicted survival beyond 12months was zero according to the modified Tokuhashi score. The surgical indication was essentially palliative. Evolution showed regression of pain in 84.6% of cases, and stabilization and improvement in motor deficit in 80.6%. Median postoperative survival was 16months. CONCLUSION: Our results highlight the interest of surgery for pain relief, spinal stabilization and improvement in neurological function in patients with spinal metastases of bronchopulmonary cancer, and the unreliability of predictive survival scores.

Hypnosis reduces food impulsivity in patients with obesity and high levels of disinhibition: HYPNODIET randomized controlled clinical trial.

BACKGROUND: The obesogenic environment of Western countries raises questions about its current management. Some clinical studies have explored hypnosis, although the current state of knowledge does not lead to definitive conclusions about its efficacy. OBJECTIVES: We assessed the impact of Ericksonian hypnosis and self-hypnosis on disinhibition of eating in adults with obesity and high food impulsivity levels, compared with standard nutritional education. METHODS: From September 2014 to July 2015, adults with BMI (in kg/m2) of 30-40 and a high disinhibition score [>8 on the Three Factor Eating Questionnaire (TFEQ-51)] were included in a randomized controlled trial. The control and hypnosis groups received the same standard nutrition education in 8 workshops. In the hypnosis group, subjects had 8 sessions of hypnosis combined with training in self-hypnosis. Disinhibition (primary outcome) and other scores from the TFEQ-51 as well as anthropometric, food intake, cardiometabolic, and physical activity variables were collected at inclusion and at 8 mo. RESULTS: Of 82 randomly assigned adults, 70 participated in all sessions; 80 participated in ≥1 session and were included in the main analysis (hypnosis group, n = 41; control group, n = 39). After 8 mo of follow-up, disinhibition scores adjusted for baseline values were lower in the hypnosis group, with a mean between-group difference of 4.2 (95% CI: 2.8, 5.5; P < 0.001); 67.7% of adults in the hypnosis group had normalized their disinhibition (compared with 11.1% in control; P < 0.0001). Differences for weight (1.8 kg; 95% CI: -0.1, 3.7 kg; P = 0.052), BMI (0.8; 95% CI: 0.1, 1.4; P = 0.028), susceptibility to hunger score (2.2; 95% CI: 1.0, 3.3; P < 0.001), and its 2 subscales also favored the hypnosis group. CONCLUSIONS: In the management of adults with obesity and a high disinhibition score, hypnosis and self-hypnosis can significantly improve the deep mechanisms of eating behaviors and seem to have a beneficial effect on weight loss.This trial was registered at clinicaltrials.gov as NCT02292108.

A rare localisation of intra-abdominal focal fat infarction: The falciform ligament. Contribution of imagery.

Pathological conditions of the falciform ligament are rare, one of which is the twisting of a fatty fringe that can lead to fatty infarction of the peritoneal fat. To our knowledge, only 21 cases with radiological documentation have been published in the literature. Ultrasound and computed tomography facilitated prompt diagnosis of this rare finding. The condition is best managed conservatively, but sometimes, a surgical intervention is necessary. We report herein a case of torsion of fatty falciform ligament appendage in a 73-year old female.

In-plane InGaAs/Ga(As)Sb nanowire based tunnel junctions grown by selective area molecular beam epitaxy.

In-plane InGaAs/Ga(As)Sb heterojunction tunnel diodes are fabricated by selective area molecular beam epitaxy with two different architectures: either radial InGaAs core/Ga(As)Sb shell nanowires or axial InGaAs/GaSb heterojunctions. In the former case, we unveil the impact of strain relaxation and alloy composition fluctuations at the nanoscale on the tunneling properties of the diodes, whereas in the latter case we demonstrate that template assisted molecular beam epitaxy can be used to achieve a very precise control of tunnel diodes dimensions at the nanoscale with a scalable process. In both cases, negative differential resistances with large peak current densities are achieved.

[Knee dislocation at chu Gabriel TOURE : therapeutic and evolutionary aspects]. / Luxations du genou au chu Gabriel TOURE : aspects therapeutiques et evolutifs.

INTRODUCTION: Dislocations of the knee are serious, involving the functional prognosis and sometimes the vital prognosis of the limb concerned. The aim of our work was to assess the functional results of our care. MATERIALS AND METHODS: This were a prospective study concerning patients with dislocation of the knee, treated and followed in the Department of Orthopedics-Traumatology at the CHU Gabriel TOURE from January 2015 to October 2018. RESULTS: We collected 30 patients with knee dislocation. The male sex predominated (60%) with a sex ratio of 1.5. The average age was 32.56 years. AVP was the main etiology with 83.3%. The mechanism was direct in 86.7%. Standard knee X-ray with front and side views was performed in all patients. Posterolateral dislocation was the most common type of pathology (20%). Associated lesions were observed in 56.6%. The response time was less than 6 hours in 100%. The treatment was orthopedic in 93.3%. Complications were dominated by knee laxity with 43%. At the average follow-up of 18.9 months, the functional results were good in 20%. CONCLUSION: Knee dislocations are the prerogative of the young subject. Accidents due to motorcycles are the main circumstances. Associated lesions are frequent. Orthopedic treatment is still relevant but the evolution is still unpredictable despite the early treatment.

CONCLUSION: les fractures de l'acétabulum touchent fréquemment l'adulte, surtout de sexe masculin. Les complications sont dominées par les douleurs mécaniques, la boiterie et la coxarthrose précoce. Les résultats anatomiques qui conditionnent les résultats fonctionnels sont moins bons avec le traitement orthopédique.

[Study of the prevalence of antibodies to some arboviruses in the population of the Republic of Guinea].

INTRODUCTION: Acute febrile diseases kill more than 250,000 people annually in West Africa. Malaria and typhoid fever traditionally occupy most of the total structure of registered fevers. However, these data do not fully reflect the true overall disease patterns in the West African region. This is due to the fact that diagnosis is mainly based on the clinical signs of the infectious process, suggesting that a certain number of diseases may be caused by arboviruses. The detection of specific antibodies (ABs) to infectious pathogens in the blood sera of residents of a particular area is a reliable indicator of the circulation of these pathogens in a particular territory.The aim of this study was to determine the prevalence of antibodies to a number of arboviruses: Dengue (DENV), West Nile (WNV) (family Flaviviridae), Crimean-Congo hemorrhagic fever (orthonairo)virus (CCHFV), Batai (Batai virus), Bhanja (BHAV) (order Bunyavirales), Chikungunya (CHIKV), and Sindbis (SINV) (family Togaviridae) in the population of the Republic of Guinea. MATERIAL AND METHODS: In total, a panel of 2,620 blood serum samples from people living in all landscape and geographical areas of Guinea was collected for the study. Detection of IgG antibodies was performed using an enzyme-linked immunoassay (ELISA). RESULTS: In total, ABs to Batai virus were detected in 144 samples (5.5%), BHAV in 58 (2.2%), WNV in 892 (34.0 %), DENV in 659 (25.2 %), CCHFV in 58 (2.2 %), CHIKV in 339 (12.9 %), and SINV in 52 samples (2.0 %). DISCUSSION: The obtained results indicate serological evidence of the spectrum of arboviruses in the population of all landscape and geographical zones of the Republic of Guinea, confirming their active circulation in this territory. CONCLUSION: Given the high epidemiological significance of arbovirus infectious diseases, it is an urgent task to continue studying its share in the structure of febrile diseases in the territory of the Republic of Guinea.

[Profile and quality of life of patients with rheumatoid arthritis in Guinea Conakry and Cameroon]. / Profil et qualité de vie de patients atteints de polyarthrite rhumatoïde en Guinée Conakry et au Cameroun.

INTRODUCTION: rheumatoid arthritis (RA) dramatically affects the quality of life of patients. The objective of our study was to study the link between the activity of the disease and the quality of life of Guinean (Conakry) and Cameroonian patients with RA. METHODS: pilot multicentric cross-sectional study (Ignace Dean National Hospital of Conakry in Guinea and Efoulan Yaoundé District Hospital in Cameroon) for 15 months (1st October 2016 to 30th January 2018). The diagnosis of RA was based on the criteria of the ACR/EULAR. Disease activity was assessed by DAS 28. The EMIR questionnaire and the Steinbrocker score were used to assess quality of life. RESULTS: fifty-two patients, 82% of whom were women. The total EMIR score was 5.06±0.50 as a relatively impaired quality of life. Alteration of quality of life was more marked on psychic components (6.78±0.99) and pain (5.37±0.99). The work component was the least affected (4.03±0.98). DAS28 was significantly related to psychic components (p=0.036, R=0.29), pain (p=0.076, R=0.25), physical (p=0.0029, R=0.41), and at the overall quality of life (total EMIR) (p=0.027, R=0.31). CONCLUSION: the most significant of RA on quality of life was related to pain (EVA-pain) and RA activity (DAS 28). The results of this pilot study will have to be confirmed by a largest study.

[Mosquitoes, Distribution and Specific Richness in Eight Countries of Africa: Cape Verde, Mauritania, Senegal, Gambia, Mali, Burkina Faso, Niger and Chad]. / Moustiques, Distribution et Richesse Spécifique dans Huit Pays D'afrique: Cap-Vert, Mauritanie, Sénégal, Gambie, Mali, Burkina Faso, Niger et Tchad.

Mosquitoes (Diptera, Culicidae) form a family of insects of considerable public health importance. Mention of their presence/absence was tackled in the literature and by specialized websites for eight African countries: Cape Verde, Mauritania, Senegal, Gambia, Mali, Burkina Faso, Niger and Chad. In total, 216 species have been recorded belonging to 13 genera: Anopheles (48 species), Aedeomyia (2), Aedes (62), Coquillettidia (6), Culex (54), Culiseta (1), Eretmapodites (7), Ficalbia (3), Lutzia (1), Mansonia (2), Mimomyia (7), Toxorhynchites (4) and Uranotaenia (19). The presence of these species in the study area is certain except for three species whose presence is doubtful. This specific richness represents 6% of the world's richness. The countries with the highest specific richness are Burkina Faso (162 species), Senegal (143) and Mali (110); the country with the lowest richness is Cape Verde (11). This richness is lower in the north in hyper-arid climate and higher in the south in sub-humid climate. Chad is the least well inventoried country. All species are considered native, with the exception of Ae. (Stegomyia ) albopictus (the Asian tiger mosquito) introduced in 2016 into Mali and possibly Ae. (Ochlerotatus ) caspius into Mauritania and Ae. (Stg. ) aegypti introduced into Nouakchott, Mauritania. This synthesis of the knowledge may be useful for vector control, public health, and future research.

[Evolution of Uterine Ruptures at the Maternity of Ignace Deen National Hospital (Chu of Conakry)]. / Évolution des Ruptures Utérines à la Maternité de L'hôpital National Ignace Deen (Chu de Conakry).

Uterine rupture is a common obstetrical drama in our delivery rooms that has become exceptional in developed countries. In developing countries including Guinea, this tragedy is one of the major concerns of the obstetrician. The objectives of this work were: to evaluate the frequency of uterine rupture in the department, to describe the socio-demographic and clinical characteristics of the patients, to identify the factors favoring the occurrence of uterine rupture, to evaluate the maternal-fetal prognosis and propose a prevention strategy to reduce maternal and fetal morbidity and mortality by uterine rupture. This was a descriptive study with data collection in two phases, one retrospective lasting 18 months from July 1, 2017 to December 31, 2018 and the other prospective, lasting 18 months also from January 1, 2019 to June 30, 2020 both carried out at the maternity ward of the Ignace Deen National Hospital. We collected 84 cases of uterine rupture out of 18,790 deliveries, i.e. a frequency of 0.44%. During the same time 10,067 cesarean sections were realized, i.e. one laparotomy for uterine rupture for 120 cesarean sections. The average age of the patients was 28.14 years with a standard deviation of 2 years and the average profile is that of a housewife (51.8%), multiparous (44.6%), evacuated from peripheral maternity (85.5%) and having an insufficient number of antenatal consultations (82.6%). In 93.1% of cases, the uterine rupture had occurred in delivery centers, peripheral maternity hospitals and on the way, the uterine ruptures were mostly spontaneous (65.1%), and occurred in a healthy uterus (59.0%). Uterine rupture was more frequently complete (83.33%). Surgical treatment was more frequently conservative with hysterorrhaphy (88.1%). We recorded 12 maternal deaths, i.e. a case fatality rate of 14.6%. On admission, almost all of the women showed no signs of fetal life. To reduce the frequency of uterine ruptures, better organization of emergency obstetric and neonatal care and better screening for risk factors for obstructed labor during prenatal consultations should be encouraged.

[Socio-Anthropological Determinants of the High Prevalence of Obstetric Fistula in Guinea]. / Déterminants Socio-Anthropologiques de la Prévalence Élevée des Fistules Obstétricales en Guinée.

Objective: The purpose of this study was to analyse the socio-anthropological determinants (representations, beliefs, practices and perceptions of health services) of the high prevalence of obstetric fistulas in Guinea. Patients and methods: From January 15 to February 15, 2018, we carried out a qualitative study in three health centres (one urban and two rural). The study focused on biological mothers who attended the centres to get vaccinated their children. The data were collected by semi-structured individual interview. Results: None of the 42 respondents could link the occurrence of obstetric fistulas and obstructed labour. Participants at all three study sites believed that obstructed labour and obstetric fistula have a mystical origin. In Kissidougou, the respondents thought that obstructed labour and obstetric fistulas are caused either by soubaya, sorcery in Malinké or the evil spell korte in Malinké cast by an enemy, or the bad behaviour of the parturient which means either she practices adultery or if she behaves disrespectfully towards elders. In Dubréka, the respondents linked the occurrence of labour dystocia and obstetric fistula to witchcraft koromikhi in Sousou. In Labé, some respondents thought that obstructed labour and obstetric fistula are due to divine punishment in local dialect lette Allah when the woman does not respect her husband or has contracted the pregnancy out of the legal union. Others deemed that childbirth is difficult because of the narrowness of the delivery route in Fulani lawol ngol no faadhi in parturients who do not have sex during pregnancy or when the woman had not adequately had female circumcision, in local dialect o suuwaaki laabhi which means, part of the clitoris was left in place during the excision. The majority of respondents had a poor perception of health services (male staff, lack of privacy, poor hygiene, abuse). Several cultural practices (early wedlocks, genital mutilations, dietary restrictions, home deliveries) also induce obstetric fistulas. Conclusion: Respondents' cultural beliefs and practices regarding childbirth limit women's attendance at maternity hospitals during childbirth and favour obstetric fistulas.
