Trends in malnutrition among children under 5 in Niger: a retrospective analysis of demographic and nutrition surveys comparing 2008-2014 with 2015-2021.

OBJECTIVES: For decades, Niger, a Sahelian country in Africa, has faced serious food and nutrition crises. Policies and strategies have been implemented by the Government, with the support of its partners, to address this public health problem. The current study was conducted to assess trends in malnutrition among children under 5 years of age. By comparing results from 2008 to 2014 with results from 2015 to 2021, this study aimed to check the efficacy of strategies and policies that were implemented to combat malnutrition. STUDY DESIGN: Retrospective study. METHODS: Data from the annual nutrition survey Standardized Monitoring and Assessment of Relief and Transitions and the Demographic and Health and Multiple Indicator Surveys were used. Meta-analyses were performed on the data as a whole and in each age group by time period. For analysis of age groups, the 95% confidence interval (CI) data were missing, thus an estimate was made from the 'design effect' calculated based on existing CIs. RESULTS: Institutional arrangements had not changed from 2008 to 2014 to 2015-2021, and there were very few changes to existing strategies and policies. The prevalence of Global Acute Malnutrition and Global Chronic Malnutrition (GCM) both remained above critical thresholds for each year in both periods. GCM was above the emergency threshold for both periods, indicating that all regions of the country were affected by malnutrition. The most populated regions (40%) of Maradi and Zinder were the most affected by malnutrition. These two regions also had highest incidence of poverty and the least health service coverage. CONCLUSIONS: Despite the implementation of various policies and strategies, the nutritional status of children under 5 remains an important public health problem.

Persistence of the cholera epidemic in the Tillabery district (Niger): epidemiological analysis of determining factors.

To analyze the determinants of the persistence of the cholera epidemic in Tillabery to obtain a durable solution. Case-control study conducted in three health centers in June 2013 in Tillabery. Cholera cases were confirmed by laboratory testing or epidemiologically linked with a confirmed index case. Controls were individuals with no history of diarrhea, of the same sex, from the same village and with an age difference that did not exceed five years. A logistic regression model was used to analyze the appearance of cholera according to the determining factors. The analysis showed significant association between the occurrence of cholera and variables related to behavior. The adjusted OR confirm higher risks of cholera for persons in households with more than five inhabitants (crude OR = 1.55 95 % CI (1.06 to 2.28) and adjusted OR 95 % CI 2.68 (1.79 to 4.56)), or in contact with a person with diarrhea (crude OR = 1.86 95% CI (1.26 to 2.75) and adjusted OR = 1.61 95% CI (1.5 to 2.68)), and who report not washing their hands after defecation (crude OR = 3.44 95% CI (2.20 to 5.41) and adjusted OR = 2.76 95% CI (1.73 to 3.79)). This study concludes that the Tillabery cholera victims are primarily those with hazardous hygienic practices. Niger must define operational recommendations to limit the continuance of cholera in certain river areas, particularly in the Tillabery.

Intensive dietary intervention promoting the Mediterranean diet in people with high cardiometabolic risk: a non-randomized study.

AIMS: Mediterranean diet (MD) is acknowledged to exert a number of beneficial health effects. We assessed the efficacy and the durability of a 3-month intensive dietary intervention aimed at implementing the MD on body weight and cardiometabolic risk factors in subjects at high risk. METHODS: One hundred and sixteen subjects participated in the study (71 assigned to the intensive intervention and 45 to the conventional intervention). The intensive intervention consisted of 12 weekly group educational meetings and a free-of-charge supply of meals prepared according to the MD model. The conventional intervention consisted of an individual education session along with monthly reinforcements of nutritional messages by the general practitioner. All participants were followed up for 9 months. RESULTS: The two groups had similar pre-intervention characteristics. After the intervention, mean body weight decreased significantly in both groups (p < 0.001). However, the intervention group lost more weight (6.8 ± 4.0 vs. 0.7 ± 1.3, p < 0.0001) and showed a greater reduction in plasma glucose, triglycerides, blood pressure and an increase in HDL cholesterol than the control group (p < 0.01-p < 0.002). In the subgroup of participants with type 2 diabetes, there was a significant reduction in HbA1c level following the intensive (p < 0.0001) but not the conventional intervention. At follow-up, weight loss still persisted in the intervention group (p < 0.0001), while it was lost in the control group. Both interventions significantly reduced blood pressure in the long term (p < 0.001). A significant reduction in daily total energy intake was observed in both groups with a greater reduction in saturated fat and a higher increase in fibre intake in the intervention than in the control group (p < 0.009 and p < 0.001, respectively). CONCLUSIONS: A 3-month intensive dietary intervention inspired to the traditional MD produced greater and more durable weight loss and improvement in cardiometabolic risk profile than the conventional intervention.

[Medical fault or professional negligence? Case studies in two recovery nutrition centers in Niger]. / Faute médicale ou négligence professionnelle ? Étude de cas dans deux centres de récupération nutritionnelle au Niger.

In developing countries such as Niger, the risk of medical malpractice is ubiquitous in health, jeopardizing patient safety. The aim of this work was to contribute to patients' safety and respect of code of ethics and conduct in the exercise of the medical profession. The reported cases involved two children under 5 years who were admitted to nutrition rehabilitation centers, died as a result of medical malpractice. In Niger, there are no statistics on this phenomenon and a few cases found have always been considered "accident" or "fate." The establishment of an observatory collections of such information should improve their frequency, consequences and propose a prevention plan.

A simple and cheap system to speed up and to control the tumescent technique procedure: the Tedde's system.

We have devised a low cost system to quickly infiltrate tumescent solution: we call it the "Tedde's system". This low-cost system offers an improvement in quality and quantity of the infiltration because all the procedure depends on the operators, reducing also the time of the infiltration and consequently of the whole surgical procedure. Moreover, this system can be applied to other surgical procedure that requires large infiltration volumes.

A photonic wall pressure sensor for fluid mechanics applications.

In this paper, we demonstrate a micro-optical wall pressure sensor concept based on the optical modes of dielectric resonators. The sensing element is a spherical micro-resonator with a diameter of a few hundred micrometers. A latex membrane that is flush mounted on the wall transmits the normal pressure to the sensing element. Changes in the wall pressure perturb the sphere's morphology, leading to a shift in the optical modes. The wall pressure is measured by monitoring the shifts in the optical modes. Prototype sensors with polydimethylsiloxane micro-spheres are tested in a steady two-dimensional channel flow and in a plane wave acoustic tube. Results indicate sensor resolutions of ∼20 mPa and bandwidth of up to 2 kHz.

A locally aggressive solitary fibrous tumor of the leg: Case report and literature review.

INTRODUCTION: The solitary fibrous tumor (SFT) is a rare soft tissue tumor with a substantially benign clinical behavior. However, malignant neoplasms with local recurrence or distant metastases have been reported. PRESENTATION OF THE CASE: The authors present a case of an aggressive SFT of the leg, in a 55 years old Caucasian man. Radiological, histological and molecular findings are reported. The differential diagnosis, therapy and outcome of this rare tumor are also discussed. DISCUSSION: An extensive review of literature showed SFT's clinical behavior as substantially benign, anyway aggressive or malignant neoplasms have been described. The potential risk of local recurrence and distant metastasis thus suggests wide surgical resection and careful long-term follow-up. Differential diagnosis may be quite laborious as SFT can mimic a variety of benign and malignant mesenchymal tumors; immunohistochemical analysis for CD34, CD99, vimentin and bcl-2 is then mandatory. CONCLUSION: Our clinical experience confirmed that SFT may have an aggressive behavior, however, conservative surgical treatment may be successful in the long term.

Heterologous reconstruction and radiotherapy: the role of latissimus dorsi flap as a salvage.

AIM: The versatility and effectiveness of the latissimus dorsi flap as salvage in complicated heterologous reconstructions, especially with regards to radiotherapy, is examined in this retrospective review of our 10-year experience. METHOD: Twenty-eight patients with complicated heterologous reconstruction were divided into three groups: (1) 15 patients with mastectomy and immediately expander reconstruction and radiation; (2) 9 patients with previous QUART, salvage mastectomy and immediate expander reconstruction; (3) 4 patients with radical mastectomy without radiation. RESULTS: The most common complications were capsular contracture and radiodermitis in Group 1, cutaneous fistula in Group 2. Recipient site complications, after latissimus dorsi flap, were observed in seven patients (five smokers), five in Group 1, two in Group 2. Cosmetic result was scored excellent and good in 25 patients (89%). CONCLUSION: This study shows as a favourable and cosmetically satisfactory reconstruction can be achieved when combining an implant with a latissimus dorsi flap allowing the salvage of the entire heterologous reconstruction.

[Pygomelus: a surgical case report from Nigeria]. / La pygomélie: à propos d'un cas opéré au Niger.

We report a case of pygomelus, a malformation characterized by the presence of supernumerary limb. The patient was a 3-month-old girl born full term in the Zinder area of Niger. The mother had not attended prenatal visits. No drug had been administered during pregnancy and the family was not inbred. The malformation consisted of an almost fully developed third lower limb, attached to the lumbosacral spine, and of a small fleshy mass at the base of the limb resembling a penis. The appendage was removed surgically without complications and the child has been developing normally since the intervention.

[Usefulness of implantable loop recorder in the diagnosis of undetermined syncope. Report of a clinical case]. / Utilità del "loop recorder" impiantabile nella diagnosi della sincope di natura indeterminata. Descrizione di un caso clinico.

In this paper we describe the case of a 42-year-old man who presented with rather infrequent episodes of syncope. In view of this symptomatology, he had been repeatedly hospitalized and submitted to a complete diagnostic workup inclusive of brain computed tomography, head-up tilt test, repeated Holter monitoring, and electrophysiologic evaluation. Unfortunately, none of these tests allowed the formulation of a precise diagnosis. When, owing to further episodes of syncope, the patient came to our observation, after an inconclusive new series of noninvasive tests, we decided to implant an insertable loop recorder. This device revealed that a phase of severe bradycardia lasting 53 s, with 15 s of complete asystole, occurred during symptoms thus allowing us to diagnose the cause of syncope.

Failure of blood pressure to increase following erythropoietin therapy in the renoprival status.

Two anephric patients in the course of one year erythropoietin therapy improved their anemic status without changes in Mean Arterial Blood Pressure. The discordant time course behaviour of hematocrit and blood pressure points to the importance of residual renal tissue for blood pressure to develop during erythropoietin therapy in the renoprival status.

Toxicity in uremia. 1. Correlation between PTH levels and depressed cell proliferation.

Cell proliferation is significantly depressed in uremia; to assess the influence of PTH on it, normal lymphocytes were cultured in presence of uremic patients' serum with low or high plasma PTH levels (Group A; PTH less than 2.5 ng/ml; Group B: PTH greater than 12 ng/ml), and serum of normal subjects (Group C). Cell proliferation was lowered by serum from both groups (p A vs C less than 0.004; p B vs C less than 0.001). However, the depressing effect was more evident when group B serum was employed (p A vs B less than 0.002).
