ObJECTIVES To assess the extended feasibility of a telerehabilitation program and its effects on physical performance in older adults who have recently undergone transcatheter aortic valve implantation(TAVI).METHODS In this single-center feasibility study, patients underwent an eight-week telerehabilitation program, involving webbased home exercise training twice weekly, an activity tracker, access to an informative website, and one online session with a nurse, starting one-week postoperative. Data collection was performed before surgery and three months postoperative. The feasibility of the intervention was based on recruitment and adherence to the program. As a secondary outcome, we evaluated the change in six-minute walk distance from before surgery to three months *** Forty-one patients scheduled for TAVI were assessed for eligibility;15 patients(37%) were enrolled. Of these, eight were excluded after surgery due to tiredness(n = 2), non-cardiac related hospital readmission(n = 2), fluctuating health(n = 1),death during hospital stay(n = 1), and reduced cognition(n = 2). Seven patients completed the eight-week web-based intervention and were evaluated three months postoperative. Their median(IQR) age was 83 [81, 87] years, and the sample comprised three men and four women. Their walked distance improved from median(IQR) 262 [199, 463] before surgery, to 381 [267, 521]meters three months postoperative. No adverse events were *** Web-based telerehabilitation, including supervised exercise training, in older adults who have recently undergone TAVI was feasible for a small number of patients who completed the eight-week intervention. This was reflected in an improvement in their walked distance three months after the surgery. However, the low recruitment and retention rates do question the overall feasibility of this intervention in a frail, older population of post-TAVI patients.

Introduction: Also known as maternal burnout syndrome, maternal burnout is a state of physical, emotional and mental exhaustion generated by prolonged stress in the family environment. It is experienced by women in their role as mothers. Those affected can develop psychological disorders, sleep disturbances, etc., all of which impair their day-to-day lives, and thus their maternal role. The repercussions affect both the child and other family members. Objective: The aim of the present study was to investigate maternal burnout among female users of public and private health facilities in the commune of Parakou in 2023. Methods: Descriptive cross-sectional study was conducted from December 2022 to July 2023 among all mothers using public and private health facilities in the commune of Parakou. All healthy mothers with at least one biological or adoptive child fully dependent on them and living at home, who came for a consultation in one of the health facilities or for an appointment at the Expanded Program on Immunization (EPI) and gave their free and informed consent. Sampling was done for non-exhaustive convenience were included in the study. burnout was assessed using the Parental burnout Assessment (PbA) scale. Results: A total of 888 mothers meeting the inclusion criteria were surveyed. The prevalence of burnout calculated using the Parental burnout Assessment (PbA) scale was 6.19%. The risk factors for maternal burnout were poor relationships with family and friends (OR = 8.90;p = 0.045), moderate (OR = 11.71;p = 0.020) and severe depression (OR = 40.85;p = 0.001), followed by the presence of repeated nocturnal awakening (OR = 5.14;p = 0.014). Conclusion: This is a subject that is almost never discussed in African society, but whose reality is revealed by the present study, which provided statistical data on maternal burnout. From now on, the risk of burnout will no longer be discussed solely in the family context. It will also need to be explored within the fam

Introduction: Viral hepatitis b (VHL) is a public health problem, particularly in sub-Sahara Africa. The aim of this study was to assess vaccination coverage against HbV in children in brazzaville. Patients and Methods: This was a cross-sectional analytical study conducted in brazzaville health centres from January to September 2019. It involved children aged between six months and six years who received a vaccination against HbV. Sampling was exhaustive and based on stratified sampling. Results: The overall prevalence of children vaccinated against HbV in brazzaville was 96.2%. It was insufficient in the Talangai health district (79%). The pentavalent vaccine was administered to 97.7% of children, 85% of whom had received all three doses. The reasons for incomplete vaccination were parents’ ignorance of HVb (85.6%) and of vaccination (14.3%). Conclusion: Although the prevalence of vaccinated children is high in brazzaville, it is still insufficient in some health districts, particularly Talangai, because parents are unaware of the disease and of vaccination. Pentavalent is the only vaccine available in the national vaccination programme, which is why an effective national vaccination policy needs to be put in place. .

外国研究表明,平均摄入低于建议水平的ω-3长链多不饱和脂肪酸(n-3LC-PUFA)、二十碳五烯酸(EPA)和二十二碳六烯酸(DHA)对健康有益,为此,试验就蛋鸡饲料中添加EPA含量丰富的的有机微藻对鸡蛋中n-3L-多不饱和脂肪酸含量的影响进行了研究。蛋鸡分成3组,对照组饲喂标准饲粮,试验组分别在标准饲粮中添加喷雾干燥微绿球藻5.0%和10.0%。研究结果表明,微藻中的EPA很难在蛋黄脂质中积累,但优先转化为DHA和卵黄磷脂沉积。微藻的n-3LC-PUFA沉积到鸡蛋中的效率很低,但试验组鸡蛋中的n-3LC-PUFA水平仍高于对照组。此外,蛋黄的颜色从黄色变至橙红色,这可能是由于微藻类胡萝卜素转移到蛋黄中。因此,无机微藻类是一种可用于生产富含DHA鸡蛋的饲料添加剂。

biased activity of soluble guanylyl cyclase:the Janus face of thymoquinone

Acta Pharmaceutica Sinica b 2017年第4期7卷 401-408页

The natural compound thymoquinone, extracted from Nigella sativa(black cumin), is widely used in humans for its anti-oxidative properties. Thymoquinone is known for its acute endotheliumindependent vasodilator effects in isolated rat aortae and pulmonary arteries, depending in part on activation of adenosine triphosphate-sensitive potassium channels and inhibition of voltage-dependent calcium channels. The compound also improves endothelial dysfunction in mesenteric arteries of ageing rodents and in aortae of rabbits treated with pyrogallol, by inhibiting oxidative stress. Serendipitously,thymoquinone was found to augment contractions in isolated arteries with endothelium of both rats and pigs. The endothelium-dependent augmentation it causes counterintuitively depends on biased activation of soluble guanylyl cyclase(sGC) producing inosine 3',5'-cyclic monophosphate(cyclic IMP) rather than guanosine 3',5'-cyclic monophosphate. This phenomenon shows a striking mechanistic similarity to the hypoxic augmentation previously observed in porcine coronary arteries. The cyclic IMP preferentially produced under thymoquinone exposure causes an increased contractility of arterial smooth muscle by interfering with calcium homeostasis. This brief review summarizes the vascular pharmacology of thymoquinone, focussing in particular on how the compound causes endothelium-dependent contractions by biasing the activity of sGC.

Antigen specificity and receptor diversity are hallmarks of b and T cells. Only 1%-5% of all T cells bear a γδ T-cell receptor （TCR）, and these cells have features of both innate and adaptive cells. While the antigen presentation process was long ago elucidated for αβ T cells, it has remained enigmatic for γδ T cells. In a recent study by Vavassori and co-workers,1 this major gap in know-ledge was addressed and dosed.

Introduction: Females with sickle cell disease (SCD), despite having a delayed pubertal development, are subject to many worries relating to their abilities to conceive, their capacity to maintain a maternofetal-risk-free pregnancy till term and give birth to healthy children without sickle cell disease. Knowing that unplanned pregnancies are more likely to increase maternofetal morbidity and mortality, we sought out to explore the pregnancy preferences in female patients with sickle cell disease to promote healthy conception and childbirth in this vulnerable population. Methodology: We conducted a cross-sectional study involving female patients of child-bearing age with sickle cell disease followed at Laquintinie Hospital Douala or who were members of a local sickle cell association. Pregnancy preferences were determined using the Desire to Avoid Pregnancy (DAP) scale. Factors associated with pregnancy preferences were determined using multivariable linear regression model. Threshold for significance was set at p Results: Seventy-seven patients were included with a mean age of 24.71 ± 5.53 years. Forty patients (51.95%) had one sexual partner and thirteen women (32.5%) used contraceptive methods. Most patients (46.0%) responded “Strongly Agree” or “Agree” to the statement “it would be a good thing for me if I became pregnant in the next 3 months”. The mean DAP score was 1.63 ± 0.91 [1.28 ± 0.82 in those who had a sexual partner and 1.99 ± 0.86 in those who had no sexual partner]. Factors that were positively associated with DAP score were students (b = 0.32, 95% CI [0.21, 0.95], p = 0.003), monthly income ≥ 100,000 FCFA (b = 0.24, 95% CI [0.07, 0.81], p = 0.022), and not having a sexual partner (b = 0.26, 95% CI [0.11, 0.85], p = 0.012). Conclusion: Most female patients with SCD have a low desire to avoid pregnancy. This is especially true for patients who are not students, have a partner and have a low monthly income.
