Introduction: Patella tendon rupture (PTR) is a cause of handicap in athletic patients. Surgery remains the actual therapeutic modality with a variety of techniques that permits a return to sport. Our objective was to evaluate the return to sporting activities after surgical repair of a PTR. Method: We conducted a retrospective cohort study over five years from January 2016 to April 2021. We included athletes from 18 to 65 years of operating for a PTR. We evaluated: the knee functional score, the level of satisfaction, Lysholm score, VISA-P questionnaire, and return to sports. Results: A total of twenty-one cases of PTR were identified. The median age was 36 years (18 - 63). After surgery, the median follow-up was 17 months (12 - 55). All patients were able to walk at 3 months. A total of 17 patients (85%) returned to sports. The median return to sports was 6 months (5 - 11). Patients who return to a similar sport with a similar initial level of sporting activity were 45% (9 patients). The median time to return to sports for patients at a similar level of sport was 7.5 months (6 - 13). Functional scores were satisfactory;with a VISA-P score of 90/100 (25 - 100) and a Lysholm score of 98/100 (40 - 100). Conclusion: Surgical repair of PTR in athletes offers good results regarding return to sports in terms of proportion and timing whatsoever the technique. The use of protection band wires is reserved for patients with relative satisfaction during suture repair.

Open Journal of Nephrology 2024年第2期14卷 196-215页

Introduction: Acute kidney injury (AKI) is defined as a sudden and reversible deterioration in renal function. It is a life-threatening condition in hospitalized patients. Our objectives were to determine the prevalence of AKI in a nephrology department, list the causes, describe the evolutionary profile and identify the factors associated with death. Patients and Methods: We reviewed the records of patients hospitalised between 1 January 2016 and 31 October 2020 in the nephrology department of Brazzaville University Hospital. We included patients aged at least 18 years whose discharge diagnosis included the item AKI. Study variables were socio-demographic data, clinical and paraclinical signs, stage and type of AKI, etiology and evolutionary profile. Results: Of the 1823 patients hospitalised, 244 (13.38%) were hospitalised for AKI. Of these, 60.2% were boys and 39.8% girls, with an average age of 47 19 years. The average consultation time was 10 6.5 days. AKI was stage 3 in 69.57% of cases. It was functional, organic and obstructive in the order of 55.28%, 36.02% and 8.69%. Dialysis was indicated in 62 patients (38.51%) and performed in 24 patients (14.9%). In-hospital mortality was 27.95%, with an average hospital stay of 9.6 5.8 days. Metabolic acidosis and anemia were the main causes of death in 14.28% and 4.35% of patients respectively. Factors associated with death were male sex, socioeconomic level, coma, indication for dialysis and absence of dialysis, with a p Conclusion: AKI is more common in young adult males. Mortality is relatively low. Improving prognosis requires early management and access to dialysis.

Primary Budd-Chiari syndrome (BCS) is a spontaneously fatal disease characterized by an obstruction of the hepatic venous outflow tract due to thrombosis or a primary disease of the venous wall. The primary form of BCS is extremely rare. This is a disease mainly affecting young adults of both sexes. Clinical manifestations are variable;they can be asymptomatic, acute, or subacute but mostly chronic. Several causes have been identified, such as myeloproliferative syndrome, antiphospholipid syndrome, paroxysmal nocturnal hemoglobinuria, and inherited thrombotic disorders. Data on primary BCS in Sub-Saharan Africa is rare as most publications available are case reports. In these reports, the causes are unknown with poor prognosis in most cases often leading to patient death. We herein present a case report of a male patient diagnosed with a primary BCS at Yaoundé General Hospital (Cameroon) caused by a Protein C deficiency who presented with ascites decompensating liver cirrhosis. Treatment was based on anticoagulants, diuretics and laxatives administration. Two years after the diagnosis, the patient is alive with clinical and paraclinical improvement.

In the purpose to design novel antituberculosis (anti-TB) drugs agents against Mycobacterium tuberculosis (Mtb), we have built a molecular library around 42 Halimane Diterpenoids isolated from natural sources. Two Mtb enzymes drug targets (Mtb Mycothiol S-transferase and Mtb Homoserine transacetylase) have been adopted. The pharmacological potential was investigated through molecular docking, molecular dynamics simulation, density functional theory (gas phase and water) and ADMET analysis. Our results indicate that (2R,5R,6S)-1,2,3,4,5,6,7,8-octahydro-5-((E)-5-hydroxy-3-methylpent-3-enyl)-1,1,5,6-tetramethylnaphtha-lene-2-ol (compound 20) has displays higher docking score with each of the selected drug targets. In addition, this molecule exhibits a satisfactory drug potential activity and a good chemical reactivity. Its improved kinetic stability in the Mtb Mycothiol S-transferase enzyme reflects its suitability as a novel inhibitor of Mtb growth. This molecule has displayed a good absorption potential. Our results also show that its passive passage of the intestinal permeability barrier is more effective than that of first-line treatments (ethambutol, isoniazid). In the same way, this anti-TB druglikeness has shown to be able to cross the blood brain barrier.

本论文讨论了中国与撒哈拉以南非洲地区贸易合作的影响和证据:特别关注喀麦隆。该研究呼吁采用定性和定量方法的混合方法。观察和公开访谈作为调查工具,对中国和喀麦隆的1010家经济运营商进行了调查。考虑到研究的目标,发出了27份关于1010份样本的调查问卷。该研究的结果表明,covid-19对喀麦隆人口的就业产生了影响,并且由于covid-19的出现,自然贸易对某些部门有利而不对其他部门有利可图。还应该看到,中喀双方都将从合作中获益。这种关系不是慈善关系。在喀麦隆方面,它带来了基础设施的发展和出口收入的增加,为增长增加了一个积极的指数。另一方面,中国将从喀麦隆的自然资源中获取原材料。不仅如此,中国还扩大了与世界其他地区尤其是非洲的贸易联系。喀麦隆和中国之间的贸易政策必须修改,以提高喀麦隆的经济实力。在人力资源方面,喀麦隆应该加强或依赖其人力资本,而不是依靠进口专家在本国开展发展项目。这可以通过训练来实现。

Dear Editor,The development of reversible photochromic materials combining efficient writing/erasing properties, low-cost and environmentally friendly compositions is a breakthrough challenge and a subject of many research works in the last decades. In this perspective, transparent oxide glasses are promising since their production is ensured by a simple melt-quenching technique and a proper laser writing setup is able to give rise to a localized photochromic effect, opening opportunities for 3D optical data storage.

Research Progress on the Relationship between Coronary Artery Calcification and Chronic Renal Failure

引用

Chinese Medical Journal 2018年第5期131卷 608-614页

作者： Jun Lai gael Akindavyi Qiang Fu Zhi-Liang Li Hui-Min Wang Li-Hua Wen Department of Cardiology Zhujiang Hospital Southern Medical University Guangzhou Guangdong 510280 China

Objective： Coronary artery calcification （CAC） is thought to be a controlled metabolic process that is very similar to the formation of new bone. In patients with chronic renal failure （CRF）, CAC is very common, and CAC severity correlates with the deterioration of renal lilnction. We summarized the current understanding and emerging findings of the relationship between CAC and CRF. Data Sources： All studies were identified by systematically searching PubMed, Embase, and CNKI databases for the terms ＂coronary calcification＂, ＂＇chronic renal failure＂, ＇~vascular smooth muscle cell＂, and their synonyms until September 2017. Study Selection： We examined the titles and abstracts of all studies that met our search strategy thoroughly. The full text of relevant studies was evaluated. Reference lists of retrieved articles were also scrutinized for the additional relevant studies. Results： CRF can accelerate CAC progression. CRF increases the expression of pro-inflamrnatory factors, electrolyte imbalance （e.g., of calcium, phosphorus）, parathyroid hon^none, and uremic toxins and their ability to promote calcification. These factors, through the relevant signaling pathways, trigger vascular smooth muscle cells to transtbrm into osteoblast-like cells while inhibiting the reduction of vascular calcification factors, thus inducing further CAC. Conclusions： Coronary heart disease in patients with CRF is due to multiple factors. Understanding the mechanism of CAC can help interventionists to protect the myocardium and reduce the prevalence of coronary heart disease and mortality.
