Measurement of intratesticular sex steroid concentrations in men informs both the development of male hormonal contraceptives and the understanding of male infertility. Given the challenges of using invasive techniques to measure testicular hormone physiology, our group has used a minimally-invasive fine-needle aspiration technique to measure intratesticular hormones in normal healthy men. Herein, we present a post-hoc analysis of the safety and efficacy of testicular fine-needle aspiration （FNA） completed as part of six clinical trials. From 2001 through 2011, a total of 404 procedures were conducted among 163 research volunteers, 85.9% of which were successful in obtaining sufficient fluid for the measurement of intratesticular steroid concentrations. Pain was the most common side effect, with 36.8% of procedures associated with moderate procedural pain and 4.7% with severe procedural pain. Postprocedural pain was uncommon and abated within a few days. Mild local bruising occurred with 14.9% of procedures. Two serious adverse events （0.5%） required surgical intervention. The risk of an adverse event was not associated with age, body mass index, testicular size, or the volume of fluid aspirated. Testicular FNA to obtain fluid for measurement of intratesticular steroid concentrations frequently causes mild to moderate procedural pain, but serious adverse events occur rarely. Testicular FNA has been instrumental for defining human intratesticular hormone physiology and is a minimally-invasive, safe, effective method for obtaining fluid for research on testicular physiology and pathology.

引用

Open Journal of Therapy and Rehabilitation 2024年第3期12卷 197-212页

作者： Karine Truflandier Kevin Albert jean-jacques Moraine Department of Cardio-Pulmonary Physiotherapy Hpital de La Tour Meyrin Switzerland Paediatric Intensive Care Unit Centre Hospitalier Universitaire Sainte-Justine Montral Canada Laboratoire des Sciences de la Motricit Universit Libre de Bruxelles Brussel Belgium

Background: The prolonged slow expiratory (PSE) technique can induce sigh breaths related to the Hering-Breuer reflex in *** is a specific chest physiotherapy technique often used in children to help with the clearance of secretions, reduce pulmonary obstruction and decrease ventilatory effort. Purpose: The main objective of this review was to synthesize and clarify the existing knowledge of the physiological mechanism behind the Hering-Breuer reflex and its utility in the PSE technique. The secondary objective was to provide an overview of PSE which is probably the main mechanical feature for mucus clearance in infants and to identify gaps and any further research required. Method: A comprehensive literature search was performed using PubMed/MEDLINE and Ovid EMBASE, from 1968 to January 2024, using search terms relating to “Interaction of Hering-Breuer reflex and chest physiotherapy therapy, sigh breath in infants and prolonged slow expiration technique” to create an overview of the advances and gaps in current knowledge of PSE. Result: The data obtained following treatment with PSE maneuvers in infants with histories of recurrent wheezing shows that the presence of sighs could be the main active principle of treatment. Conclusion: Changes in volume induced by PSE technique and, effects from crying may stimulate the Hering-Breuer deflation reflex and sighs in turn improving alveolar ventilation as well as lung volume in infants.

Uncovering the Challenges of Faecal Sludge Management in Benin’s Urban Hubs: The Cases of Abomey-Calavi and Natitingou

引用

Journal of Environmental Protection 2024年第7期15卷 767-780页

作者： Nikita Topanou Blaise Agbatchi Gouvidé jean Gbaguidi jacques Fatombi Fidèle Paul Tchobo Kaba Laboratory of Chemical Research and Application (LaKReCA) Department of Chemistry Faculty of Science and Technology of Natitingou University of Abomey Natitingou Bnin Laboratory of Study and Research in Applied Chemistry Polytechnic School of Abomey-Calavi University of Abomey-Calavi (LERCA/EPAC/UAC) Cotonou Bnin

The issue of faecal sludge management in developing countries remains a significant challenge due to the indiscriminate discharge of sludge into the environment. This practice generates more environmental problems than it solves. This study aims to assess the management of household faecal sludge in the communes of Abomey-Calavi and Natitingou, Benin, in order to optimise the best storage conditions for subsequent more effective treatment. To this end, a sociological survey was conducted among households in Abomey-Calavi and Natitingou, as well as among manual emptiers. The results of our studies revealed that two types of latrines are used in households. 20.55% of households use traditional latrines, while 59.83% use ordinary latrines. 7.97% of households use both types of latrine. Moreover, the depth of the latrines varies from 2.5 m to 7 m in Abomey-Calavi and from 2.5 m to 8 m in Natitingou. Among households with a latrine, 28.26% empty their pit at least once, while 71.74% have never emptied it. The emptying cost varies between 35,000 FCFA and 90,000 FCFA. The mixing of faecal sludge with solid waste, including plastic materials, makes emptying difficult due to the obstruction of the vacuum pump. The results obtained will serve as a reliable database to facilitate decision-making in the context of faecal sludge management.

Hydrogeochemical Characterization of Groundwater from Fissured Aquifers in the Angovia Mine Operating Permit Area (Central-West Côte d’Ivoire)

引用

Journal of Water Resource and Protection 2024年第1期16卷 83-101页

作者： Kouadio Michel Yao Tanina Drissa Soro Tanoh jean jacques Koua Akaie jean Fabrice Tchakray Yao Emile Desmond Konan Brou Dibi Laboratory of Sciences and Technologies of Environment University Jean Lorougnon Guede Daloa C&ocircte d’Ivoire

The main objective of this study is to determine the hydrogeochemical specificities of the groundwater of the Angovia mine operating permit, located in the Yaouré mountains in the center-west of Côte d’Ivoire. To do so, descriptive and multivariate statistical analysis methods with the SOM (Self Organizing Maps) algorithm were applied to the physicochemical parameters of 17 boreholes using the calcite (ISC) and dolomite (ISD) saturation indices. The results obtained have shown that the groundwater in the Angovia mine operating permit area has an average temperature of 27.52°C (long rainy season) and 27.87°C (long dry season) and has an average pH of 7.09 ± 0.35 during the main rainy season and 7.32 ± 0.35 during the main dry season. They are mineralized with an average electrical conductivity of 505.98 ± 302.85 μS/cm during the long rainy season and with 450.33 ± 233.74 μS/cm as average during the long dry season. The main phenomena at the origin of groundwater mineralization are water residence time, oxidation-reduction and surface inflow. The study of the relative age of the water shows that the groundwater in the Angovia mine operating permit area is mainly undersaturated with respect to calcite and dolomite. They are therefore very old in the aquifer with a slow circulation speed during the long rainy season and the long dry season.

导演的话《红鲱鱼》这个戏吸引我的是剧中那些犀利的、耐人寻味的,又让人捉摸不透的东西,它既荒诞又寓言。人类的悲欢并不相通,这个戏探讨了现代人的处境,人和人之间的对抗与疏离、困惑与矛盾。这些又何止发生在上个世纪末的巴黎?且看我们的身边。我们能否在坠入空虚的世界之际保持清醒?能否改变这一切?很多事情,戏剧也给不了答案,只是映照人类困境的一面古老镜子。某种意义上说,《红鲱鱼》文本即是“红鲱鱼”,剧作家有意无意地将你引入他设下的迷局。剧中遍布的似有非有、无法言说的模糊地带,给舞台创作带来了多种可能,我们畅游,窥视一二。

Introduction: According to the World Health Organization, globally one in six people experience infertility in their lifetime. Infertility is considered as a major and global public health issue. In most cases, women bear the burden of infertility to protect the male ego. Although men and women are equally likely to have fertility problems. The aim of this study was to identify the causes of infertility of couples residing in Libreville. Patients and Methods: This was a retrospective descriptive study performed over 2 years, from 1st January 2021 to 31st December 2022. Data was obtained from 162 couples attending the assisted reproduction department of the mother and child hospitals in Libreville. Statistical analysis was done using IBM SPSS Statistics version 22.0 software. Results: During the study period, 28.5% of couples could afford IVF treatment. The average for woman age was 39.1 ± 4.06 while the average age for male patients was 41.53 ± 7.08 years with minimum and maximum age of 34 et 66 years. More than half (58.6%) of female partners were employed in the public sector. Half of the male partners (50%) were employed in the private sector. The median duration of infertility was 6 years. Approximately 49.4% of couples were diagnosed with primary infertility. The most common causes of infertility in female patients were Fallopian tubes obstruction (53.2%), uterine factors (24.2%) and hormonal problems (19.6%). With regards to male factors infertility, testicular causes were predominant (53.6%). Oligoasthenoteratozoospermia were the major semen abnormalities (55.7%) found after semen evaluation. Both male and female partners were sub-fertile in 47.5% of cases. Unexplained infertility was found in 11% of couples. Conclusion: This study showed that the diagnostic of infertility faced by couples residing in Libreville should involve both male and female partner.

Background: Spontaneous ascites fluid infection (SAFI) is an extremely serious and frequently encountered complication in cirrhotic patients. We aimed to determine the prevalence of SAFI and the factors associated with it in the largest hospital in Cotonou. Methods: This was a retrospective descriptive and analytical study conducted from January 2013 to July 2019, at the National and University Hospital Hubert Koutoukou Maga (CNHU-HKM) in Cotonou, Benin. All patients followed in the University Clinic of Hepato-Gastroenterology and diagnosed with SAFI were included. Results: Eighty-two patients were included, predominantly males (69.5%), with a mean age of 51.5 ± 14.5 years. Among them, 32 had SAFI, i.e., a prevalence of 39%. Of the 32 cases of SAFI, the culture of ascites fluid was positive in 6 cases (18.7%). The most frequent germ found in SAFI was Escherichia coli (5 patients, 83.3%). The factors associated with SAFI in this study were: abdominal pain (p = 0.004), increased bilirubinemia (p = 0.009), decreased prothrombin level 20 (p = 0.001). Conclusion: SAFI was common in cirrhotic patients in the department. Certain clinical and paraclinical factors were associated with it, as was the severity of cirrhosis. Early diagnosis and aetiological management of cirrhosis could reduce its frequency.

Introduction The distribution of congenital heart disease (CHD) in sub-Saharan Africa is highly imprecise and varies from one region to another due to the inequality of diagnostic facilities. The aim of this study was to determine the in-hospital prevalence of congenital heart disease in children at the Mother-Child hospital of Bingerville (HME) by specifying the diagnostic, therapeutic and evolutionary aspects. Materials and methods We conducted a retrospective, descriptive, cross-sectional study at HME of Bingerville from January 2021 to December 2022. All newborns with congenital heart disease confirmed by echocardiography were included in the study. Results Of 656 admissions to the neonatology department over the study period, congenital heart disease accounted for 14.9% (98/656) of cases. In our series, 76.7% were diagnosed before the 1st week of life, with a mean chronological age of 5.18 days and extremes of 0 and 46 days. There were as many male patients (50%) as female (50%), i.e. a sex ratio of 1. These newborns were premature in 60.2% of cases, with a mean and median gestational age of 34 weeks’ amenorrhea. Most were left-right shunts (90.8%). Persistent ductus arteriosus (PDA) (48.9%) predominated, followed by atrial septal defect (38.7%), ventricular septal defect (13.3%), common trunk artery (CTA) (3.1%) and open septal pulmonary atresia (OSPA) (1%) as the primary cyanogenic heart disease. Pulmonary arterial hypertension (PAH) (50%) was primary in 38.8% and secondary (61.2%). The mortality rate was 30.6%, and all CTA patients died (100%), with a significant statistical relationship (p = 0.027). Progression under treatment was marked by clinical stabilization (68/98) in 69.4% of cases. Conclusion: Congenital heart disease is relatively common at the Bingerville HME. Access to echocardiography should be facilitated in neonatology departments for rapid diagnosis and optimal management of congenital heart disease in newborns.
