Introduction: In low-income countries, severe anemia represents a significant risk of mortality. It is generally the consequence of a lack of correct community-based management of mild and moderate anemia and its etiologies. Our study aimed to evaluate the community practice in confronting anemia by mothers of children aged 0 - 5 years old before and during the COVID-19 period. Methods: We conducted a descriptive cross-sectional study in two phases at the pediatric ward of the regional hospital of Ngaoundere in Cameroon;before the period of the COVID-19 pandemic from December 2018 to May 2019 and during the pandemic period from December 2020 to May 2021. It was a volunteer sample. Were included in this study all mothers of children aged 0 - 5 years present in the pediatric ward at the time of the survey who agreed to freely answer our questionnaire. Results: Of the 152 mothers surveyed in the “Before COVID-19” group, 69% went to a health facility when they suspected their children were anemic, 20% gave grenadine juice (Red colored soda), 7% went to marabous, 2% bought street medicines and 2% used other home-made potions. Of the 92 mothers included in the “During COVID-19” group, the majority did not go to a health facility: 36% gave grenadine juice and other potions, 26% went to marabouts, 23% bought medicines from the street and only 13% went to a health facility;2% did nothing. The average Group rank is not statistically significantly different between the before and during the COVID-19 periods (p = 0.89). Conclusion: Community behavior and practice in confronting anemia deteriorated during the COVID-19 pandemic, with the majority of mothers resorting to non-effective out-of-hospital solutions. The consequence can be an increase in infant mortality. While waiting for the end of the pandemic, it is judicious and urgent to review the whole health system in Africa and especially in countries with limited resources. We propose developing multiple advanced strategies t

简介成像技术的进步极大改善了肝局灶性病变（FLLs）的非侵入性检测和成像。由于良性FLLs的发病率极高，因此病变成像极其重要。相对而言，包括原发性肝癌和转移癌在内的肝癌是最常见的肿瘤疾病。

以玉米整个生长期野外热红外辐射观测数据为基础,对两种组分亮温分类方法作了比较,并对玉米地组分亮温的变化特征展开了分析。结果表明,农田亮温组分的数目和数值随测量时间和日期改变。在整个测量期间,在当地时间中午前后,农田呈现出3个亮温组分植被、被阳光照到的亮土和植被阴影下的暗土。观测早期,植被亮温分布相对集中;随着农田植被覆盖率的增高,植被亮温分布逐步分散,组分间温差缩小,部分亮温值相互重叠。产生这些现象的原因将在以后的研究中加以探讨。

New sequencing technologies such as Illumina/Solexa, SOLiD/ABI, and 454/Roche, revolutionized the biological researches. In this context, the SOLiD platform has a particular sequencing type, known as multiplex run, which enables the sequencing of several samples in a single run. It implies in cost reduction and simplifies the analysis of related samples. Meanwhile, this sequencing type requires an additional filtering step to ensure the reliability of the results. Thus, we propose in this paper a probabilistic model which considers the intrinsic characteristics of each sequencing to characterize multiplex runs and filter low-quality data, increasing the data analysis reliability of multiplex sequencing performed on SOLiD. The results show that the proposed model proves to be satisfactory due to: 1) identification of faults in the sequencing process;2) adaptation and development of new protocols for sample preparation;3) the assignment of a degree of confidence to the data generated;and 4) guiding a filtering process, without discarding useful sequences in an arbitrary manner.

提出了一种基于感知模型的声辐射系统音质评价方法。采用此模型可应用Moore提出的参数以测试其是否适用于间接辐射扬声器的音质评价。对3种压缩式驱动器进行了测试,并且记录了它们在各种测试信号以及各种输入电压条件下的测试结果。基于上述实验结果,从不同的角度提出了解决该问题的方法:(a)考虑经典的音质评价参数,如粗糙度、尖锐度和音调;(b)应用由Moore建议的从感知模型获取的参数。此外,还进行了一项针对25人的心理声学实验,尽管实验结果只是初步的并极大依赖于参考信号,但仍然能够表明其与Rnonlin值的良好相关性。

Background: Chronic heart failure is a public health problem worldwide. It has a high mortality rate and is accompanied by a decreased functional capacity and alteration of the quality of life. Objective: This study aimed to assess the cardiovascular functional capacity of a group of patients suffering from heart failure using the 6-minute walk test (6 MWT). Methods: This was a cross-sectional study carried out in the cardiology unit of Douala’s general hospital for 4 months. We included all eligible patients aged 18 years or more who had stable chronic heart failure and gave informed consent. Those who had an acute coronary syndrome (≤1 month), tachycardia (HR ≥ 120 bpm), high blood pressure (SBP ≥ 180 mmHg and/or DBP ≥ 100 mmHg) and reduced mobility due to orthopaedic reasons were excluded. A 6 MWT was done according to the American Thoracic Society guidelines. The 6 MWT result was considered poor for - 450 m and good for >450 m. Results: We recruited a total of 81 patients (61.7% women) with a mean age of 65.9 ± 10.6 years. The most frequent risk factor for heart failure was high blood pressure (77.8%), alcohol consumption(69.1%) and a sedentary lifestyle (53.1%). The left ventricular ejection fraction was mostly preserved (42.0%) or mildly altered (46.9). The 6 MWT results were poor in 55.6% of cases, average in 19.8% of cases and good in only 24.7% of cases. More than half (59.3%) of the participants perceived the effort as being difficult. The cardiovascular functional capacity was significantly associated with age, heart failure stage and physical activity (p Conclusion: Most patients suffering from chronic stable heart failure in the general hospital of Douala have poor cardiovascular functional capacity.

Purpose. To report three cases of adenoviral keratoconjunctivitis in patients who have undergone photorefractive keratectomy and that just developed subepithe lial infiltrates. Methods. Description of patients that developed postoperative adenoviral keratoconjunctivitis after photorefractive keratectomy without influe nce in the final visual outcome. Results. All patients presented adenoviral kera toconjunctivitis 2-3 months after refractive surgery. They developed multiple p inpoint subepithelial infiltrates in six eyes, without haze development. The final uncorrected visual acuity was better or equal to 20/30. Conclusion. Although patients undergoing photorefractive ker atectomy might develop severe corneal scarring following ocular infections, such events may follow their natural evolution.
